[0029] Reference Figure 1-Figure 4 According to an embodiment of the utility model, a multi-station ball cage polishing device includes a processing table 11, a vertical plate 12 is arranged on the processing table 11, and a clamping device 101 is arranged on the vertical plate 12;

[0030] The clamping device 101 includes a sleeve 13 rotatably connected to the vertical plate 12, a locking groove 14 opening to the right is provided in the sleeve 13, two clamping plates 15 distributed up and down are provided in the locking groove 14, and a driving component for making the two clamping plates 15 move toward each other so that the ball cage can be clamped and fixed is also provided in the sleeve 13, and a No. 1 motor 16 for driving the sleeve 13 to rotate is also provided on the vertical plate 12;

[0031] In addition, the processing table 11 is also provided with a polishing device 102 for grinding the ball cage located between the clamping plates 15 .

[0032] In this embodiment, the driving assembly includes two pressure plates 17 hinged on the outer curved surface of the sleeve 13, and the sides of the two clamping plates 15 that are away from each other are each provided with a sliding rod 18 that extends to the outside of the locking groove 14 and can be connected to the right end of the pressure plate 17. The outer curved surface of the sleeve 13 is also slidably connected to the left and right with a slip ring 19, and the outer diameter of the slip ring 19 gradually increases in the left direction. It also includes a clamping mechanism that drives the slip ring 19 to move left and right to control the angle of the pressure plate 17 clockwise.

[0033] In order to enable the multi-station ball cage polishing equipment to synchronously clamp multiple ball cages, the clamping device 101 is provided with several front and rear distributed ones. In this embodiment, the clamping mechanism is provided with a No. 1 cylinder 30 on the vertical plate 12, and the end of the No. 1 piston rod extending from the No. 1 cylinder 30 is equipped with a push plate 20, and the slip ring 19 is provided with a plurality of empty grooves for accommodating the sleeve 13, and the push plate 20 is connected to each of the slip rings 19 through a plane bearing 21, and the plane bearing 21 is located outside the empty groove, and the pressure plate 17 is also connected to the outer curved surface of the sleeve 13 through a spring.

[0034] Specific clamping and unlocking process:

[0035] First, the staff places the ball cage in the locking groove 14 and makes the end of the ball cage abut against the bottom of the locking groove 14. Then the staff controls the No. 1 cylinder 30 to make the push plate 20 move to the right. At this time, the plane bearing 21 and the slip ring 19 will move to the right. When the slip ring 19 moves to the right, it will lift the left end of the pressure plate 17 and make the right end of the pressure plate 17 move inward. At this time, the slide rod 18 will be pressed down by the pressure plate 17, so that the two clamps 15 in one locking groove 14 are close to each other and clamp the ball cage in the locking groove 14.

[0036] When the polishing device 102 completes polishing the clamped ball cage, the sleeve 13 is in a stationary state, and then the push plate 20, the plane bearing 21 and the slip ring 19 move to the left. At this time, the spring will drive the pressure plate 17 to reset and make its right end tilt up. At this time, the two clamping plates 15 are away from each other, and it is convenient for the staff to remove the ball cage located in the locking groove 14.

[0037] In this embodiment, the connection method between the pressure plate 17 and the sliding rod 18 is that a card slot is provided in the right end surface of the pressure plate 17, and a connecting column extending forward and backward is installed in the card slot, and a connecting slot for accommodating the connecting column is provided in the left side surface of the sliding rod 18. During the swinging process of the pressure plate 17, the connecting column will slide left and right in the connecting slot to support the sliding rod 18 to only move up and down.

[0038] In this embodiment, each of the sleeves 13 is connected by a synchronous belt 31 . With this arrangement, one motor 16 can drive all of the sleeves 13 to rotate.

[0039] The clamping plate 15 is provided with an arc surface so that it can better clamp the ball cage. In order to facilitate the clamping device 101 to clamp ball cages of different sizes, in the second embodiment of the polishing device 102, the clamping plate 15 includes a straight plate 22 and a curved plate 23. The side of the curved plate 23 away from the straight plate 22 connected thereto is an arc surface, and the curved plate 23 and the straight plate 22 are connected by bolts. The staff can replace the curved plate 23 to enable the clamping device 101 to clamp ball cages of different specifications.

[0040] The polishing device 102 includes a lifting plate 24 connected to the processing table 11 by sliding up and down through a clamp, a fixed plate 25 is provided at the upper end of the lifting plate 24, and a No. 3 motor 32 for controlling the lifting and lowering of the lifting plate 24 is provided on the processing table 11, a curved block 26 is installed on the lower side of the fixed plate 25, and a tool 27 capable of moving along the curved surface trajectory of the curved block 26 is installed in the lower curved surface of the curved block 26, the tool 27 includes a tool head extending to the lower side of the curved block 26 and a control block extending to the rear side of the curved block 26, a No. 2 cylinder 28 is provided on the fixed plate 24, a No. 2 piston rod extending from the No. 2 cylinder 28 is connected to a push-pull plate 29, and the control block is connected to the push-pull plate 29 by sliding up and down.

[0041] The specific polishing process is as follows: when the staff completes the clamping of the ball cage through the clamping device 101, the staff controls the No. 3 motor to make the lifting plate 24 descend until the tool head in the tool 27 is attached to the outer surface of the ball cage, and then the No. 2 cylinder 28 pulls the push-pull plate 29 to the right. During this process, the tool 27 will move along the trajectory and move upward relative to the push-pull plate 29, and polish the ball cage clamped by the clamping device 101.

[0042] In this embodiment, the arc surface blocks 26 and the cutters 27 can be arranged in a plurality of groups distributed front and back, and the push-pull plates 29 can be connected to each of the cutters 27, so as to perform synchronous processing on a plurality of ball cages.
