Description

Technical Field

[0001] The utility model relates to the technical field of clamping structures, and specifically, to a bearing clamping structure for bearing production and processing. Background Technique

[0002] A bearing is a component that plays a role in fixing and reducing the load friction coefficient during the mechanical transmission process. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. When a bearing is produced and processed, a clamping structure is required to clamp and limit the bearing for subsequent stable processing.

[0003] After retrieval, it is proposed in Chinese Patent Application No. CN202321660054.1 that a bearing fixture structure for bearing production and processing includes a mounting base. At the middle position of the top end of the mounting base, a support table is fixedly connected. On both sides of the top end of the mounting base, support plates are fixedly connected. On one side of the support plate, a first cylinder is installed. The output end of the first cylinder is installed with a first clamping plate. A collection box is placed inside the support table. A mesh plate is installed at the top end of the support table. The top end of the mesh plate is fixedly connected with a fixing plate. In the above prior art, when clamping a bearing, the support plates are pushed to move by the cylinders at both ends, so that the support plates squeeze and limit both sides of the bearing.

[0004] In the above prior art, although the bearing can be squeezed and clamped by the support plates pushed by the cylinders on both sides, in this clamping method, the worker needs to hold the bearing all the time during the clamping process and only release it after the bearing is clamped by the support plates on both sides. When the support plates clamp the bearing, since the support plates only limit the bearing in a straight line, when the bearing is subjected to a large external force in the vertical direction, it is easy for the bearing to fall off from the support plates, thereby affecting subsequent processing. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bearing clamping structure for bearing production and processing, which solves the problem that the clamping stability of the bearing clamping structure for bearing production and processing in the prior art is poor when clamping a bearing, thus affecting the subsequent processing efficiency.

One end of the positioning component is fixedly connected to a rotating component, and a moving component is inserted into one end of the rotating component. One end of the moving component is fixedly connected to a clamping component.

[0007] Preferably, as the above technical solution, the adjusting component includes a first motor fixedly connected to the outer side of one end of the base, and a double-headed threaded rod is fixedly connected to the output shaft of the first motor. The end of the double-headed threaded rod away from the first motor is rotatably connected in the base, and threaded plates are engaged with the outer sides of both ends of the double-headed threaded rod.

[0008] Preferably, as the above technical solution, the positioning component includes a connecting plate fixedly connected to the outer side of the upper end of the threaded plate, and a round plate is fixedly connected to the inner side of one end of the connecting plate.

The end of the rotating shaft away from the second motor passes through and is connected in the connecting plate and the round plate, and a turntable is fixedly connected to the end of the rotating shaft away from the second motor. A sliding groove is formed inside the end of the turntable away from the rotating shaft.

[0010] Preferably, as the above technical solution, the moving component includes a plug rod inserted into the sliding groove, and a limiting block is fixedly connected to the outer side of the middle end of the plug rod. The end of the limiting block away from the plug rod is inserted and slides in the round plate.

[0011] Preferably, as the above technical solution, the clamping component includes a clamping plate fixedly connected to the end of the plug rod away from the turntable, and a rubber pad is fixedly connected to the outer side of one end of the clamping plate.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] As Figure 1 - Figure 5 shown, the present invention provides a technical solution: a bearing clamping structure for bearing production and processing, including a base 1. An adjustment component is arranged in the middle of the base 1, and a positioning component is fixedly connected to the upper end of the adjustment component. One end of the positioning component is fixedly connected to a rotating component, and a moving component is inserted into one end of the rotating component. One end of the moving component is fixedly connected to a clamping component. When clamping a bearing, the adjustment component can be started first to drive the positioning component to move to a suitable position, then the bearing is placed in the clamping components on both sides, and then the adjustment component is started again to drive the positioning component to perform pre-positioning clamping on the bearing. Subsequently, the rotating component is started to drive the moving component to move, so that the moving component drives the clamping component to perform secondary clamping and fixing on the bearing, enabling the clamping structure to perform multi-directional clamping and restriction when clamping and fixing the bearing, thereby improving the stability after clamping.

[0022] As Figure 1 , 4 shown, the adjustment component includes a first motor 2 fixedly connected to the outer side of one end of the base 1, and the output shaft of the first motor 2 is fixedly connected to a double-headed threaded rod 21. The end of the double-headed threaded rod 21 away from the first motor 2 is rotatably connected in the base 1, and threaded plates 22 are engaged with the outer sides of both ends of the double-headed threaded rod 21. When the first motor 2 is started, the output shaft of the first motor 2 drives the double-headed threaded rod 21 to rotate. After the double-headed threaded rod 21 rotates, through the engagement with the threaded plates 22, the threaded plates 22 drive the positioning component and the like to move, facilitating the adjustment of the distance between the two positioning components, so as to perform pre-positioning clamping on the bearing by the positioning component.

[0023] As Figure 1 , 4As shown, the positioning component includes a connecting plate 3 fixedly connected to the outer side of the upper end of the threaded plate 22. One end of the connecting plate 3 is fixedly connected with a circular plate 31 inside. After the first motor 2 starts, the output shaft drives the double-headed threaded rod 21 to continue rotating, so that the connecting plates 3 and circular plates 31 on both sides clamp and limit the two sides of the bearing, facilitating the pre-positioning and limiting of the bearing by the movement of the connecting plates 3 and circular plates 31 on both sides.

[0024] As Figure 1 , 4 shown, the rotating component includes a second motor 4 fixedly connected to the outer side of the end of the connecting plate 3 away from the circular plate 31. The output shaft of the second motor 4 is fixedly connected with a rotating shaft 41. One end of the rotating shaft 41 away from the second motor 4 passes through and is connected in the connecting plate 3 and the circular plate 31. One end of the rotating shaft 41 away from the second motor 4 is fixedly connected with a turntable 42. A chute 43 is opened inside one end of the turntable 42 away from the rotating shaft 41. After the second motor 4 starts, the output shaft drives the rotating shaft 41 and the turntable 42 to rotate. After the turntable 42 rotates, it moves with the assistance of the moving component through the rotation of the chute 43, facilitating the rotation of the output shaft of the second motor 4 to drive the rotating shaft 41 and the turntable 42, so that the chute 43 opened in the turntable 42 simultaneously pushes the four groups of moving components to move.

[0025] As Figure 1 , 4 shown, the moving component includes a plug rod 5 inserted into the chute 43. A limiting block 51 is fixedly connected to the outer side of the middle end of the plug rod 5. One end of the limiting block 51 away from the plug rod 5 is inserted and slides in the circular plate 31. The plug rod 5 drives the clamping component to move with the assistance of the limiting block 51 as the chute 43 is pushed, facilitating driving the four groups of clamping components to move simultaneously to clamp and limit the two ends of the bearing.

[0026] As Figure 1 , 4 shown, the clamping component includes a clamping plate 6 fixedly connected to one end of the plug rod 5 away from the turntable 42. A rubber pad 61 is fixedly connected to the outer side of one end of the clamping plate 6. When the plug rod 5 moves, it drives the clamping plate 6 and the rubber pad 61 to move, and the four groups of clamping plates 6 and rubber pads 61 are used to perform secondary clamping and fixing on the outer end of the bearing.

[0027] Working principle: When clamping and processing the bearing, first start the first motor 2. After the first motor 2 starts, the output shaft drives the double-headed threaded rod 21 to rotate. After the double-headed threaded rod 21 rotates, through meshing with the threaded plate 22, the threaded plate 22 drives the connecting plate 3, etc. to move. When the two groups of connecting plates 3 move to the appropriate positions, first turn off the first motor 2 at this time, then place the bearing between the two side clamping plates 6 and the rubber pads 61, and then start the first motor 2 again. After the first motor 2 starts, the output shaft drives the double-headed threaded rod 21 to continue rotating, so that the connecting plates 3 and the circular plates 31 on both sides clamp and limit the two sides of the bearing. Subsequently, start the second motor 4. After the second motor 4 starts, the output shaft drives the rotating shaft 41 and the turntable 42 to rotate. After the turntable 42 rotates, the insertion rod 5 moves with the assistance of the limiting block 51 through the rotation of the sliding groove 43. When the insertion rod 5 moves, it synchronously drives the clamping plate 6 and the rubber pad 61 to move, so that the clamping plate 6 and the rubber pad 61 perform secondary clamping on both ends of the bearing. After the clamping is completed, turn off the second motor 4 to process the bearing. After the processing is completed, first start the second motor 4 to make the output shaft of the second motor 4 rotate in the reverse direction, so that the clamping plates 6 and the rubber pads 61 at both ends return to their positions. Subsequently, start the first motor 2 to make the output shaft of the first motor 2 rotate in the reverse direction, so that the threaded plate 22 drives the two groups of connecting plates 3 and the circular plates 31 to return to their positions. Finally, take out the processed bearing.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
