[0003] The bearing clamping fixture of the existing technology generally uses a screw to drive the moving block to move and the fixed block to fix both sides of the bearing. However, it is difficult for the moving block to move quickly when driven by the screw. At the same time, the clamping on both sides does not have high precision and cannot fully clamp the bearing, thereby reducing the efficiency of the bearing processing process.

[0004] Therefore, it is necessary to invent a high-precision bearing processing device to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a high-precision bearing processing device, which drives the turntable to rotate, so that the transmission shaft and the clamping block in the limit groove opened inside the turntable move, and the three groups of clamping blocks clamp the bearing. During the movement of the clamping block and the transmission shaft, the slider moves in the slide groove opened on the workbench surface, thereby improving the stability of the movement of the clamping block. Such a setting can not only clamp quickly, but also avoid vibration of the bearing during the polishing process, thereby affecting high-precision processing, so as to solve the problem that the bearing clamping fixture in the above-mentioned background technology generally drives the moving block to move and the fixed block to fix both sides of the bearing, but the moving block is difficult to move quickly by the lead screw, and the clamping on both sides does not have high precision, and the bearing cannot be fully clamped, thereby reducing the efficiency of the bearing processing process.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-5 A high-precision bearing processing device shown includes a base 1 for supporting the bearing processing device;

[0028] A workbench 2 is installed above the base 1 and is used to place bearings. A frame 3 is installed below the workbench 2. A bracket 5 is fixedly installed at the rear of the base 1. A first drive motor 6 is fixedly installed above the bracket 5. The output end of the first drive motor 6 is fixedly connected to a screw rod 7. The outside of the screw rod 7 is movably connected to a connecting seat 8. A second drive motor 9 is fixedly installed above the connecting seat 8. The output end of the second drive motor 9 is fixedly connected to a polishing wheel 10.

[0029] The clamping mechanism 4 is installed above the workbench 2 and is used to clamp the bearing. The clamping mechanism 4 includes a slide 401 and a turntable 403. The slide 401 is provided around the workbench 2. A slider 402 is movably connected inside the slide 401. A turntable 403 is movably installed above the workbench 2. The turntable 403 has a limiting groove 404 provided on its four sides. A transmission shaft 405 is slidably connected inside the limiting groove 404. A clamping block 406 is provided on the upper end of the transmission shaft 405.

[0030] The protective component 11 is installed under the connecting seat 8 and is used for protection. By driving the turntable 403 to rotate, the transmission shaft 405 and the clamping block 406 in the limiting groove 404 opened inside the turntable 403 are moved, and the three groups of clamping blocks 406 clamp the bearing. During the movement of the clamping block 406 and the transmission shaft 405, the slider 402 moves in the slide groove 401 opened on the surface of the workbench 2, thereby improving the stability of the movement of the clamping block 406. Such a setting can not only clamp quickly, but also avoid vibration of the bearing during the polishing process, thereby affecting high-precision processing.

[0031] like Figure 3 As shown, the center line of the transmission shaft 405 intersects with the center line of the slider 402, and the limiting groove 404 is set to an arc shape. The transmission shaft 405 moves in the limiting groove 404 inside the transmission shaft 405, so that the clamping blocks 406 are stable and move closer and farther away from each other, and the limiting groove 404 is set to an arc shape, in order to cooperate with the turntable 403 to pull the clamping blocks 406 to move towards each other during the rotation process.

[0032] like Figure 1 、 Figure 4 and Figure 5 As shown, the protective component 11 includes a protective cover 1101, which is installed below the connecting seat 8 and around the polishing wheel 10. During the processing of the polishing wheel 10, the protective cover 1101 prevents debris from flying around, thereby avoiding debris flying everywhere and causing physical harm to surrounding workers.

[0033] like Figure 5 As shown, a groove 1102 is provided on the lower surface of the protective cover 1101, and a spring 1103 is provided inside the groove 1102. A top block 1104 is fixedly connected below the spring 1103. The spring 1103 is provided between the protective cover 1101 and the top block 1104 to play a buffering role and avoid damage to the protective cover 1101 due to excessive force during movement.

[0034] The working principle of the utility model is as follows: first, the external power supply is connected, and then the bearing to be processed is placed in the middle of the turntable 403, and then the motor in the frame 3 is turned on to drive the turntable 403 to rotate. When the turntable 403 rotates, the transmission shaft 405 and the clamping block 406 in the limit groove 404 opened inside the turntable 403 move, and the three groups of clamping blocks 406 are clamped close to the bearing. During the movement of the clamping blocks 406 and the transmission shaft 405, the slider 402 under the transmission shaft 405 is moved in the slide groove 401 opened on the surface of the workbench 2, thereby improving the stability of the movement of the entire clamping block 406. Such a setting can not only clamp quickly, but also avoid vibration of the bearing during the polishing process. Then, the switch of the first drive motor 6 is turned on to drive the screw rod 7 to rotate, and the rotation of the screw rod 7 drives the connecting seat 8 and the connecting seat 8 below and the external protective cover 1101 to descend, and the protective cover 110 1 is selected as transparent. When the polishing wheel 10 contacts the bearing, the first drive motor 6 switch is turned off, and the spring 1103 inside the protective cover 1101 squeezes the top block 1104 on the workbench 2. This not only plays a buffering role, but also avoids damage to the protective cover 1101 caused by excessive force during movement. Next, the second drive motor 9 switch is turned on to drive the polishing wheel 10 to process the bearing surface. The debris generated by the processing will be blocked by the protective cover 1101 to avoid splashing out. When the bearing is processed, the second drive motor 9 switch is turned off, and the first drive motor 6 switch is turned on to drive the screw rod 7 to rotate counterclockwise, and the entire connecting seat 8 is returned to its initial position. Finally, the second drive motor 9 switch is turned off, and then the bearing is loosened through the steps just now to change the side to continue processing. When all processing is completed, the external power supply is cut off. In this way, the use process of the high-precision bearing processing device is completed.

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
