Description:
CNC HORIZONTAL MILLING MACHINE WITH TWO MOVABLE COLUMMS

The Related Art

The invention relates to CNC (Computer Numerical Control) counters used for giving geometric shape to certain surfaces of work parts made from any material by means of rasping.

The invention particularly relates to CNC machines which are capable to provide processing of opposite parallel surfaces of work parts by means of attaching to CNC lathes once.

Background of the Related Art

In today's manufacturing and sale concept, all auxiliary members used are structured constantly. For that reason, manufacturing method which is one of manufacturing method of CNC machines requires some new designs.

The most important problem encountered in operating principle of CNC machines called as former related art occurs in process of opposite parallel surfaces of work part. For instance, after one surface of the work part is processed, the other surface which is in opposite parallel direction of the said surface is to be demounted from the place where it is mounted and is to be reversed or rotated on a ground. The above mentioned problems occur at this point. One of them is waste of time. Manual reverse of the work part for each surface in opposite parallel direction is defined as waste of time. Because during this time period, no surface can be processed. The second problem is that after reversing the work part for processing other surface, the reference surface and positions of the part connected must be caught again by means of a special work. Otherwise, the surface matching desired to be achieved between two opposite parallel surfaces cannot be achieved. When the opposite parallel surfaces are desired to be processed symmetrically, achieving the desired result will be difficult. As a result, the operator must work with the same care while connecting and disconnecting the work part. Being subject to personal capabilities of the operator so as to achieve the desired surface quality and not to have manufacturing faults requires preparation of special connection fixtures. In addition, the operator has a too narrow and obstacle working area during changing the position of the work part for process of the different surfaces of the work part, which restricts intervention and therefore, fault percentage in adjustment of reference positions of the other surfaces to be processed is very high. Therefore, probable accident risks arise.

As movement of heavy parts is required n the related art, use of high quantity of power is required in the related art.

Purpose of the Invention

From the current status of the related art, the purpose of the invention is to eliminate the existing disadvantages in CNC machines used for achievement of desired geometry by means of rasping on the outer surface of opposite parallel surfaces of work part to be processed by help of development made therein.

Another purpose of the invention is to provide simultaneous process of opposite parallel surfaces of the work part by means of single connection to be made before start of process of work part. Thus occurrence of any size and position error between surfaces is prevented by means of same process of both opposite parallel surfaces. In other words, reference position deficits that might arise from dismantling and re-connection of the work part are eliminated. Also the process conducted on the said surfaces can be made on three axis.

A further purpose of the invention is to provide selection of cutting sets by the spindle on the column performing the process during process of parallel surfaces of the opposite direction on the work part.

Another purpose of the invention is to broaden the opportunity to reach the part even in position when the work part is connected to CNC machine. Intervention required to be made on the work part can be made easily. Thus the work accidents that are likely to occur are prevented.

A further purpose of the invention is to provide time saving of 60% in working period of the related art, which is considerably big percentage.

In the new technique, power saving is provided by means of moving light group whose load does not change, instead of moving heavy part, and processing speed also increases.

The structural and characteristics features of the invention and all advantages will be understood better in detailed descriptions with the figures given below and with reference to the figures, and therefore, the assessment should be made taking into account the said figures and detailed explanations.

To sum up the basic purpose, in order to process both surfaces facing opposite directions simultaneously by means of connecting work part to milling table, CNC horizontal milling used for process of work part made of any material aimed to have desired geometric form through rasping from parallel surface of opposite direction and consisting of a body parallel to the ground, lathe table containing an assembly located on the body and where the work part can be connected, cooling liquid tank to eliminate the high temperature occurring due to friction during rasping provides a new geometry by means of two columns through active use of three axis on both surface and set stockpiling body containing multiple number of cutting sets.

Detailed Description of the Invention

The embodiment of the invention indicated in figure 1 is a two column (4) CNC horizontal milling providing desired geometry to the work part by rasping from both surfaces parallel to each other at the same time.

The body (1) containing columns (4) which are chipping members and lathe table (2) which is part connection organ and also functioning as skeleton of entire system is a fixed part. The said elements are mounted on the body (1). It contains lathe table (2) allowing rigid connection of work part and supporting the body (1). Horizontal sliding (3) connected to the body (1) provides linear traveling of column (4) along X axis without vibration.

Column (4) containing elements providing shaping by chipping on three axis on the work part and also containing auxiliary members providing traveling of the said elements is shown in figure 1 and figure 1a. It contains vertical sliding (6) allowing the said traveling in Z traveler (5) providing traveling of column (4) on vertical axis, that is, Z axis which is one of the three axis.

Serious heating occurs in cutting sets as a result of big friction forces generated during chipping on the work part. In order to prevent occurrence of bigger problems to be caused by such heating in cutting sets, cooling liquid is used and cooling liquid is * supplied from cooling liquid tank (7). The required electrical cables have been located in cable conveyor (8) so as to not prevent blocking during traveling. Power transmission organ (9) is needed for traveling of the columns (4) on horizontal sliding (3) in horizontal axis, in other words, x axis. The rack used in the related art can be used as the said power transmission organ (9). The need to change the cutting sets located in groups on the system according to structure of the surface where chipping is conducted or according to the desired shape is necessary during processing the work part. In order to meet this need, the column (4) contains set stockpiling member (11) connected thereon.

Travel of column (4) in Y axis, one of the three axis, in other words, travel of power transmission organ (9) perpendicular to rack is provided by means of Y traveler (12).

Although automatic tool change so called as ATC is known method, positioning of required tool stockpiling units (11) for both surfaces provides ergonomic feature and allows enhancement of processing speed.

The invention consists of two columns (4). The said columns (4) are positioned symmetric to each other. As seen in figure 1, lathe table (2) is located on both sides of the lathe table

(2) in a manner allowing process of both surfaces of work part parallel to each other and in opposite directions on the router table (2). Both columns (4) are specified reference points of work part connected onto the router table (2). The said reference points are starting point, in other words, zero points of each three axis. The path and distance of traveling of cutting tools on each of three axis as per the geometry to be made on the work part are commanded from control panel. The commands of both columns (4) must be programmed for each of two surfaces. In addition, another matter required to be paid attention during programming is that appropriate cutting tools should be selected for different processes. When the start button is pressed, both columns (4) start to move and parallel opposite surfaces are started to be processed simultaneously.

The invention provides a great amount of power and time saving when compared to related art as both columns (4) working mutually are capable to move on three axis. Movement of column (4) on horizontal plane in X axis, in other words parallel to counter table (2) is provided by means of rack which is power transmission organ (9). Pinion contacting the power transmission organ (9) is located in lower part of the column (4). Movement of pinion on power transmission organ (9) X axis provides forward movement on X axis. Pinion is driven by a servo engine located in the system. Movement of column (4) in vertical direction, in Z axis, in other words in direction perpendicular to counter table (2) is provided by a vertical sliding (6) and moved screw spindle as indicated in figure 1a. Here a screw spindle is connected to a servo engine and driven thereby. Movement of column (4) in Y axis, in other words in direction perpendicular to X axis is provided by spindle mounted onto the assembly.

As shown in Figure 1 , movement of columns (4), particularly linear movement on X axis can be provided along distance in respect to two other axis. For that reason, after processing the surfaces of the work part desired to be processed, moving away of the columns (4) from the work part in adequate amount can be provided. As a result thereof, the operator can easily make any operations such as position change, taking measurement on the work part. In other words, the operator is provided with a wide range of working field.

All members required for movement and functioning of a column (4) as described above are also true for other column (4). It provides same movement capabilities for both columns (4).

The invention cannot be limited to the illustrative embodiments given under this section. Alternative embodiments that can be developed by persons skilled in the related art on basis of basic factors covered under scope of protections indicated under claims shall mean violation of the invention.
