A ROTARY TABLE MECHANISM

Technical Field

The present invention relates to a rotary table mechanism which is grouped from one point by integrating the table and stations and where pick-and-place applications are used in fields like assembly line, supply systems etc. Prior Art

Movement system used in the state of art is provided by pneumatic, hydraulic or servo motors and this leads to the necessity of designing the rotary table separately from the movement system. In the applications where the movement system is mechanical cams are used. In both applications, the movement is limited and difficult manufacture of the rotary table systems, addition of new parts and adjustment difficulty lead to great disadvantages. Complex structure thereof causes the system maintenance to be difficult and expensive. As there are too many motor parts, there are more than one energy consumption points. Accordingly, energy consumption in the existing systems is too much. As the systems used are electrical and electronical, it makes providing startup and continuity of the system difficult.

In the invention of the utility model application No. TR200301654, a pneumatic rotary table is described. The invention relates to rotary tables capable of performing step wise stops at particular angle degrees. The system generally consists of two pistons operating in a synchronized way. When the system begins to operate, the table at the end of the bearing piston pushes the support slide forward. The ball-shaft on the rotary table enters into the channel on the table support slide. When the bearing piston is switched into open position, the bearing piston pushes the support slide forwardly. The rotary table rotates with the desired angle by the drive from outside. In the meantime, the table support slide crashes to the crash bumper.

In the invention of the utility model application No. TR200903985, a hydraulic jack with rotary table is described. The invention relates to a hydraulic jack with rotation mechanism used for lifting the parts down such as gearbox, differential motor etc. within motors and lifting them up for assembly. Said rotation mechanism consists of portable connection elements; a rotary table connected to the portable connection elements and rotating 360°; a fixed table comprising a table shaft, a fixed table gap through which the table shaft passes and a fixed table legs; a tapered bearing and a straight bearing overspread onto the table shaft; a bearing house into which the tapered bearing and the straight bearing are placed; a table shaft nut enabling compression by being placed under the fastening element and table shaft.

The rotary table mechanism (1 ) of the present invention used in pick-and-place applications in fields like assembly line, supply systems etc. comprises:

- at least one bush (2) which provides an upwards-downwards movement, - at least one fixed plate body (3) through which the bush (2) passes, - at least one rotating module (4) fixed onto the plate body (3),

- at least one shaft (5) transmitting the movement of the rotating module (4) and providing a rotating movement,

- at least one fixture mounting plate (6) which is located on the rotating module (4) and through which the shaft (5) passes,

- at least one fixed support table (7) which is located on the mounting plate (6) and through which the shaft (5) passes,

- more than one column shaft (8) which are connected to the support table (7) from one end thereof and which extend upwardly,

- at least one movable table (9) to which the other end of the column shaft (8) is connected,

- at least one main gear (10) which is located on the table (9) and which gets the rotation movement from the shaft (5) and more than one gear (1 1 ) around the main gear (10),

- at least one core with bearing (12) which can move forwardly and backwardly,

- at least one lever (13) between the gear (1 1 ) and the core with bearing (12), more than one connection hole (14) used for connecting the gears onto the rotating module, and

- at least one stroke adjustment channel (15) adjusting the connection point on the gear (1 1 ) of the lever (13) connected to the gear (1 1 ).

In the rotary table mechanism (1 ) of the present invention, the bush (2) moves the table (9) downwardly and upwardly. In a preferred embodiment, the shaft (5) receiving movement from the rotation module (4) is located within the bush (2). During the downward and upward movement of the bush (2), the shaft can transfer the rotation movement to the main gear (10).

In the rotary table mechanism (1 ), the plate body (3) is a fixed element through which a shaft (5) passes and onto which the rotation module (4) is connected.

In a preferred embodiment of the invention, the rotation module (4) is fastened onto the plate body (3) via connection elements.

In the rotary table mechanism (1 ) of the present invention, the shaft (5) is an element having a screw structure which can turn the main gear (10) on the table (9) to the left or right. The gears (1 1 ) on the main gear (10) get their movement from the main gear

(10) . The shaft (5) moves the table (9) upwards and downwards via the bush (2) used for performing upward and downward movements. The rotation movement transmitted from the shaft (5) provides the forward-backward movement of the core (12) by moving the main gear (10) and all of the gears ( 1 ) at the same time.

There is a connection table (6) and a support table (7) on the connection table (6) on the upper part of the rotation module (4) respectively. The connection table (6) is used for connecting the fixture elements and the support table (7) carries the column shaft (8), the table (9), the main gear (10), the gears (1 1 ), the core (12) and the lever (13).

In the rotary table mechanism (1 ) of the present invention, there is the main gear (10) on the upward-downward moving table (9) and there are connection holes by which the gears (1 1 ) located around the main gear (10) are connected.

In a preferred embodiment of the rotary table mechanism (1 ), the main gear (10) is arranged in the middle of the table (9) such that it can receive movement from the shaft (5). There is more than one gear (1 1 ) around the main gear (10). The levers (13) connected to the gears (1 1 ) transmit the movement from the main gear (10) to the core with bearing (12).

In a preferred embodiment, the core (12) moves the elements forwardly and backwardly at the end thereof which receive movement from the gear (1 1 ) by means of the lever (13). The levers (13) are distance-adjusted elements transmitting the centrifugal movement from the gears to the core (12). By the adjustment part located on the lever (13), the distance of the end part of the core (12) to the center can be adjusted. In a preferred embodiment, the core with bearing (12) transforms the circular movement to the linear movement. In a preferred embodiment of the invention, the connection hole (14) enables the gears

(1 1 ) to be placed onto the table (9) and does not prevent the gears (1 1 ) to rotate.

The channel (15) used for stroke adjustment can adjust the connection point on the gear (1 1 ) of the lever (13) connected to the gear (1 1 ). Thus, the distance of the forward-backward movement can be adjusted by utilizing the centrifugal feature. In the rotary table mechanism (1 ) of the present invention, the bush (2) moves the table (9) downwardly and upwardly by the movement and the levers (13) can be moved forwardly and backwardly thanks to the threaded shaft (5) within the center of the table (9). As the movements in the invention are mechanical, the possibility that the mechanisms damage each other is eliminated and a controlled operation can be performed.

In the frame of these basic concepts, a variety of modification can be performed relating to the rotary table mechanism (1 ) of the invention and the invention cannot be limited by the examples described herein and it is principally as is described in the claims.
