Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, and more specifically, the utility model relates to a fixing mechanism for bearing production. Background Art

[0002] A bearing is a mechanical element that restricts relative motion within the required range of motion and reduces friction between moving parts. The design of a bearing can provide free linear motion of moving parts or free rotation around a fixed axis, or prevent motion by controlling the vector of the normal force acting on the moving parts.

[0003] During the bearing production process, operators often use corresponding fixing mechanisms to fix the bearings. In the actual use of the existing fixing mechanisms, although they have basic fixing functions, general fixing mechanisms usually adopt the fixing method of bolts and nuts. This not only requires operators to use specific tools for disassembly and assembly operations, but also the steps of disassembly and assembly operations are relatively cumbersome. This not only reduces the fixing efficiency of the mechanism for bearings, but also increases the labor intensity of operators. Therefore, it needs to be improved. Summary of the Utility Model

The forward and backward movement of the moving block 4 will cause the first clamping plate 7 to move left and right.

[0029] When the pneumatic cylinder 3 starts to operate, it will cause the moving block 4 to move horizontally forward and cause the two inclined rods 5 to move. At this time, under the limiting effect of the rectangular groove 2, the two moving rods 6 will drive the two first clamping plates 7 to move horizontally away from each other.

[0030] Among them, a limiting groove 8 is opened on the right side of the top inside the mounting frame 1, a limiting block 9 is movably connected with the inside of the limiting groove 8, and the bottom of the limiting block 9 is fixedly connected with the top of the moving block 4.

[0032] Among them, a driving motor 10 is fixedly connected to the left side of the top inside the mounting frame 1, the other end of the output shaft of the driving motor 10 is fixedly sleeved with a rotating shaft 11, and the other end of the rotating shaft 11 is fixedly sleeved with a gear 12.

[0033] When the driving motor 10 is started, it will cause the rotating shaft 11 to drive the gear 12 to rotate.

[0034] Among them, the top and bottom of the outer surface of the gear 12 are respectively meshed and connected with a first toothed plate 13 and a second toothed plate 14, and the left side of the second toothed plate 14 is fixedly connected with a connecting rod 17.

[0035] When the gear 12 rotates, it will cause the first toothed plate 13 and the second toothed plate 14 to move towards each other.

[0036] Among them, mounting rods 15 are fixedly installed inside the mounting frame 1 on the left and right sides of the first toothed plate 13 and the second toothed plate 14 respectively, a limiting rod 16 is fixedly connected between the mounting rods 15, and the outer surface of the limiting rod 16 is movably sleeved with the inner surfaces of the first toothed plate 13, the second toothed plate 14 and the connecting rod 17 respectively.

[0042] The working principle and usage process of the present utility model:

[0043] First, place the bearing to be processed between the first clamping plate 7 and the second clamping plate 20. Then, start the air cylinder 3 first, which will cause the moving block 4 to drive the limiting block 9 to move horizontally forward under the limiting action of the limiting groove 8, and drive the two inclined rods 5 to move. At this time, under the limiting action of the rectangular groove 2, the two moving rods 6 will drive the two first clamping plates 7 to move horizontally away from each other, and finally the rapid fixing effect on the inner ring of the bearing will be achieved, improving the efficiency of the fixing operation of the device and reducing the labor intensity of the operator.

[0044] After the inner ring of the bearing is fixed, then start the driving motor 10, which will cause the rotating shaft 11 to drive the gear 12 to rotate. At this time, under the limiting action of the limiting rod 16, the first toothed plate 13, the second toothed plate 14 and the connecting rod 17 will move horizontally towards each other along the outer surface of the limiting rod 16, and drive the two vertical rods 18 and the second clamping plate 20 to move horizontally towards each other together under the limiting action of the sliding groove 19, thereby achieving the fixing effect on the outer ring of the bearing, realizing the fixing effect on both the inner ring and the outer ring of the bearing at the same time, and thus avoiding the situation that the bearing rotates during the subsequent processing, and further ensuring the subsequent processing accuracy.
