FIELD OF THE INVENTION

The invention relates to an apparatus that enables the surface to be sharpen by using sandpaper in order to make the drill bits suitable for reuse in case of wear.

The invention is related to an apparatus that ensures that the drill bits, which are defined as micro drill bits with small diameters such as 0.5 mm to 3 mm, that can no longer function due to the wear of the tip parts, controlled abrading of the tip parts by using at least one abrasive material to make the tip parts suitable for reuse.

PRIOR ART

Drill bits are generally used to drill products. Drill bits, which are generally called micro drill bits and whose diameter varies up to 0.5 mm (between 0.5-3 mm) are used especially in carving/engraving processes (jewelry, rosary, etc.) Mentioned drill bits are generally made of carbide material and are manufactured resistant to wear. However, considering that it is used to remove material from the surface during use, the tip parts wear out over time. Especially the excessively worn drill bit cannot fulfill its task completely. If the drill bit is worn, the product is discarded and a new drill bit must be used.

The condition of the drill bit with a diameter of 0.5-3mm which is used in many industrial areas where small holes or abrasion is needed directly affects the labor. In order to ensure the high quality of the products obtained, it is necessary to use a drill bit that has not a weared tip.

In a working/industrial area where continuous drilling/carving/machining is carried out, the biggest consumable expense is drill bits. The constant use of new drill bits increases the cost of production. In the prior art, a standard drill bit has at least two surfaces at an angle of 118° or less to each other at the tip, and these surfaces have cutting edges at their edges. The sharpness of the intersection edge and cutting edges is important for dril ling/machining performance.

When the drill bit becomes, blunt users may want to sharpen the same drill in case with the angle of the drill bit is abraded in a way that ensures re-sharpening bit instead of using a new bit. However, this process requires constant practice and while it is easy to apply in large drill bits, but it is not possible to perform it in micro drill bits. In addition, if the sharpening process is not done correctly, the drill bit cannot perform the material removal at the appropriate level.

In the LISPTO patent document with publication number US6676500B1 , an equipment that provides sharpening of drill bits is mentioned. The equipment in mentioned invention is complex and requires a costly investment for the end user. The related device has an electric motor and provides automatic sanding and sharpening of the drill bit.

As a result, all abovementioned problems have made it necessary to make an improvement in the relevant technical field.

AIM OF THE INVENTION

The present invention aims to eliminate the abovementioned problems and to make a development in the relevant technical field.

The main purpose of the invention is to reveal the apparatus structure for drill bits with diameters between 0.1 -5mm, especially micro drill bits, that enables sharpened by positioning them at suitable angles on an abrasive material.

Abrasion on the said movement elements (30) and the apparatus body (1) is prevented and only the drill bit (B) is eroded in a controlled manner for sharpening means with the rotation of at least one of the movement elements (30) on the sandpaper/sandstone,

Figure 4 shows the exploded view of the subject matter invention that is an apparatus (A) that enables the sharpening of the micro drill bits (B). The apparatus body (1) forming the said apparatus (A) preferably consists of an adjustable body part (10) and a fixed body part (20) that can be connected to the mentioned adjustable body part (10). Mentioned adjustable body part (10) and fixed body part (20) outer edges are conjugate with each other, and the apparatus body (1 ) is obtained when the two parts are mounted with each other, whose outer edges are evenly distributed with each other. At least one preferably two moving elements (30) that enable said apparatus body (1) to be moved on the sandpaper are positioned between said adjustable body part (10) and said fixed body part (20). Said movement element (30) is positioned on the movement element motion area (50) located on at least one of the fixed body part (20) or the adjustable body part (10), and preferably each movement element (30) is connected to the apparatus body (1 ) with movement element bearing means (31 ). In the preferred embodiment of the invention, said movement element motion area (50) consists of movement element motion recess (51 ) at the same depth with each other on the adjustable body part (10) and on the fixed body part (20). Said movement element motion recess (51 ) is at the same depth in both body parts. In this way, the movement element (30) is centered in the vertical section of the apparatus body (1 ) after the adjustable body part (10) and the fixed body part (20) are assembled with each other. In the alternative embodiment, mentioned depth may vary.

In the preferred embodiment of the invention, the movement element (30) is connected to the relevant body part via the movement element contact area (52) preferably with the movement element bearing means (31 ). The adjustable body part (10) and the fixed body part (20) are connected with each other in such a way that the movement element (30) is centered between them by means of mentioned connection. In the preferred embodiment, the said moving element bearing means (31) is a bolt and it is fixed with a nut on the opposite side of the bearing means fixing element (311 ).

In a preferred embodiment of the invention, the movement element bearing means (31 ) is one-piece with the relevant body part in the movement element contact area (52) and the said movement element (30) can be positioned directly on the body.

In the preferred embodiment of the invention, there is at least one movement element nut clearance (13) of the adjustable body part (10) and/or the fixed body part (20) for each movement element contact area (52). The said moving element may contain a solid nut on the movement element nut clearance (13), as well as the one-piece apparatus body (1) structure with threads on it instead of the said nut.

In a preferred embodiment of the invention, the movement element (30) is positioned with the or the movement element bearing means (31), which is bolted to at least one of the fixed body part (20) or adjustable body part (10), and is fixed with the bearing means fixing element (311 ), which has at least one nut. It is fixed from the outside of the other body part with the bearing means fixing element (311 ) after said body part is positioned of the said movement element bearing means (31 ).

The views of the adjustable body part (10) are given in Figure 5C and Figure 5D. The adjustable body drill bit positioning opening (14) that enables the drill bit (B) to be positioned on the said adjustable body pard (10); and said adjustable body drill bit positioning opening (14) is preferably located on the apparatus body (1 ) with the side of the movement element (30). Said adjustable body part (10) includes a flexible and one-piece flexion section body (11 ). Said flexion section body (11) is partially separated from the adjustable body part (10) by the flexion clearance (12). Preferably, upside, includes a drill bit fixing protrusion (113) in the section following the adjustable body drill bit positioning opening (14). Said drill bit fixing protrusion (113) ensures that the drill bit (B) is fixed on the Drill bit positioning opening (40) formed by the said adjustable body drill bit positioning opening (14) and the fixed body drill bit positioning opening (21 ) on the fixed body part (20). In the preferred embodiment, the said drill bit fixing protrusion (113) settles into the recesses in the form of the drill bit (B) and/or provides the fixation of the said drill bit (B) by contacting the radial structure of the drill bit (B).

The adjustable body part (10) and the fixed body part (20) that are forming the apparatus body (1) of the invention are preferably connected to each other from the Movement element contact area (52) from two edge sides. From the middle part, it is fixed through the adjustment element clearance (110) that is located on the Flexion section body (11 ). The adjusting element (111) is located in the said region and adjusts the position of the flexion section body (11 ) in the direction of the fixed body part (20). In the preferred embodiment, at least one adjustment element screw (1111 ) is located in the said adjustment element clearance (110), and the adjustment element (111 ) tightens the said adjustment element screw (1111 ) with the flexion section body (11 ) tightens the drill bit (B) and it provides fixing position of the drill bit (B).

In the preferred embodiment of the invention, there is at least one adjustment element clearance (110) on the flexion section body (11). Preferably, at least one element that ensures equal distribution of the force on the surface is positioned in the said adjustment element clearance (110). In the preferred embodiment of the invention, the mentioned element is a washer. In the preferred embodiment of the invention, the adjustment element screw (1111 ) is positioned in the adjusting element bolt positioning opening (22) that is located on the fixed body part (20). The other end of the said adjustment element screw (1111 ) can be tightened with the adjustment element (111 ) that is located on the surface on the adjustment element recess (112) with passing through the adjustment element clearance (110) located on the flexion section body (11 ) of the adjustable body part (10).

With the said tightening action, the force exerted by the drill bit fixing protrusion (113) on the drill bit (B) can be controlled and thus the drill bit (B) is tightened and fixed. A representative drawing is given for the fixation mentioned in Figure 6A. The drill bit (B) is positioned in the drill bit positioning opening (40), and the drill bit fixing protrusion (113) exerts pressure on the channels of the drill bit (B) to make the fixation by squeezing the adjusting element (111 ). The cutting edges of the drill bit (B) are fixed in the same direction as the movement element (30), which enables the apparatus body (1 ) to move linearly, preferably parallel to the apparatus body (1 ).

The part of the drill bit (B) that comes out of the drill bit positioning opening (40) of the apparatus body (1) is positioned to be parallel to the ground (edge of the apparatus which is located between drill bit (B) and movement element (40)) when the apparatus

(A) is positioned on a flat surface.

The drill bit (B), which is positioned in accordance with the apparatus body (1 ) can be sharpening with the drill bit (B) located on the apparatus (A), and at least one movement element (30) are moved on the sandpaper. This positioning is given in Figure 6B. While the movement element (30) rotates on the sandpaper, the drill bit (B) is sharpened by rubbing/friction against the sandpaper surface. An edge of the drill bit

(B) is sharpened during contact with each movement element (30) sandpaper and edge of the drill bit (B). For this reason, the drill bit (B) is positioned on the apparatus (A) in such a way that its edge to be sharpened is in the same direction as the movement element (30). Figure 3 shows the sanding direction (S), which should be parallel to the sandpaper during the sanding/sharpening process.

In the preferred embodiment, the angle between the two cutting edges at the tip of the drill bits (B) to be sharpened is defined as the drill bit (B) angle and the said angle is 118°. In the preferred embodiment of the invention, the angle of the top section where the drill bit fixing protrusion (113) is located is 118°. At this point, the drill bit (B), which is positioned in accordance with the apparatus (A), the relevant edge can be sharpened by the edge of the drill bit (B) desired to be sharpened is rubbed on the sandpaper on the movement element (30) closest to the said edge. The second edge is also sharpened by rubbing on the other edge with the other movement element (30). The angle of each cutting edge on the vertical axis is defined as the cutting angle and it is determined by performing the sanding process by tilting the movement element (30) of the apparatus (A) angularly with respect to the axis in the direction of rotation. Figure 7A and Figure 7B give a drawing showing the adjustment of the cutting angle mentioned.

Each drill bits (B) has at least one said cutting angle of the drill bit (B), and the angular tilt must be at the angle determined for the respective drill bit (B) and must be repeated for both edges. One cutting angle is suitable for 0.5-1.0 mm drill bits (B), while two cutting angles should be applied for larger diameter drill bits (B).

During the use of the invention, it is necessary to repeat the movement on the same number of friction o at the same distance during the grinding process at an angle in both directions on the sandpaper. This operation is essential to maintain the angle in both directions.

In the preferred embodiment of the invention, the first cutting angle is varying from 5° to 15° preferably linearly, and the second cutting angle is varying from 25° to 40° preferably linearly. In Figure 7A, the usage of the invention that enables the determination of the mentioned cutting angle is shown. Sharpening is done by tilting it to the right and left at the prescribed angle in the same sanding direction (S), and then the same operations are repeated in the other sanding direction (S) for each cutting angles.

In alternative embodiments of the invention, there may be changes in the above- mentioned angles. The angle of the drill bit (B) can be determined by the distance from the surface of the apparatus (A) during the positioning of the drill bit (B) on the apparatus (A), and the cutting angle depends on the angular position of the apparatus (A), and it may change during rubbing of the apparatus (A) in the axially angled position. In a preferred embodiment of the invention, it is easier to determine the cutting angle with the guiding edge (15) on the apparatus body (1). The user can more easily determine the cutting angle with the position of said guiding edge (15) relative to the ground.
