After powering on the electric push rod 11, start it, and let the output end of the electric push rod 11 stretch. When the electric push rod 11 stretches, the pull rope 103 becomes slack, and the pull rope 103 no longer pulls the positioning block 102. The positioning block 102 moves towards the bearing by elastic stretching through the second spring 101, so that the positioning block 102 pushes and fixes the bearing.

The pulley 22 in contact with the middle of the bearing is elastically contracted through the second elastic telescopic rod 21 under the pressure of the bearing, so that the pulley 22 moves inward and retracts into the first groove 2. When the bearing is removed, the second elastic telescopic rod 21 resets the pulley 22 through elasticity. The pulley 22 can effectively reduce the internal friction generated when the bearing moves in the middle of the clamping plate 19, effectively reduce the problem of wear caused by friction between the inside of the bearing and the clamping plate 19, effectively reduce the friction so that the bearing slides smoothly on the clamping plate 19, and effectively reduce the problem of movement obstruction caused by friction, effectively reduce the damage to the bearing, and effectively maintain the quality and integrity of the bearing housing processing.

[0025] As Figure 3 shown, a second groove 3 is formed in the side wall of the positioning block 102; the second groove 3 is formed on the side close to the second spring 101; a wire wheel 31 is rotatably connected to the middle of the second groove 3; one end of the pulling rope 103 is fixedly connected to the middle of the wire wheel 31; during operation, when the electric push rod 11 moves and stretches to clamp the bearing with the positioning block 102, the pulling rope 103 is in a slack state, and at the same time, the wire wheel 31 winds the slack pulling rope 103. The wire wheel 31 can effectively reduce the problems of winding and knotting of the pulling rope 103 in a slack state, can conveniently and quickly wind up the pulling rope 103, effectively reduce the chaos of the pulling rope 103, can reduce the problem of processing downtime caused by the winding of the pulling rope 103 during use, and can effectively reduce the adjustment time, thereby improving the efficiency in the bearing processing process.

[0026] As Figure 1 and Figure 4As shown in the figure, a gas pump 4 is fixedly connected to the top of the fixed plate 1; a discharge pipe 41 is fixedly connected to the middle of the gas pump 4; a hinge shaft 42 is fixedly connected to the top of the baffle 12; the discharge pipe 41 is fixedly connected to the middle of the hinge shaft 42; during operation, after the bearing is fixed, the discharge pipe 41 is rotated through the hinge shaft 42 to adjust the angle of the end of the discharge pipe 41. After the gas pump 4 is powered on and opened, air flow enters the middle of the discharge pipe 41 and is then discharged to the designated position through the end of the discharge pipe 41. By blowing air at the bearing processing position, a large amount of heat generated during the bearing processing can be effectively reduced, the reduction of heat can prevent the performance of the bearing material from deteriorating, the heat can be effectively removed to reduce the problem of thermal deformation of the bearing caused by high temperature during processing, the temperature of the bearing processing area can be effectively reduced to maintain stability during the processing, and a large amount of chips can be blown away to reduce the reduction of precision caused by chip accumulation at the bearing processing position, effectively improving the precision of bearing processing.

[0027] As Figure 1 and Figure 4 As shown in the figure, a chute 5 is opened at the bottom of the baffle 12; a third spring 51 is fixedly connected to the top of the chute 5; a slide rod 52 slides in the middle of the chute 5; the other end of the third spring 51 is fixedly connected to one end of the slide rod 52; a support rod 53 is fixedly connected to the side wall of the slide rod 52; a plurality of groups of bristles 54 are fixedly connected to the top of the support rod 53; during operation, when the bearing is placed in the middle of the clamping plate 19 and fixed, the bristles 54 are in contact with the surface of the bearing. When the bearing is larger in size, pressure is applied to the plurality of groups of bristles 54. When the bristles 54 are under pressure, the slide rod 52 slides inside the chute 5 through the support rod 53, and at the same time, the third spring 51 undergoes elastic stretching. After the bearing processing is completed, the bearing is rotated, and the surface of the bearing is cleaned by the bristles 54. The flexibility of the bristles 54 can effectively remove impurities such as dust and chips attached to the surface of the bearing, and can timely clean the dust and chips to reduce the decline of bearing processing precision. And the slide rod 52 can be flexibly applied to bearings of different sizes, and the bristles 54 can effectively reduce scratches or damage to the surface of the bearing during cleaning.

[0028] As Figure 1 and Figure 2 As shown in the figure, two sponge blocks 6 are fixedly connected to the end of the second hollow rod 13; the two sponge blocks 6 are arranged oppositely; during operation, during the movement of the pull rope 103, the end of the second hollow rod 13 is in contact with the pull rope 103 through the sponge blocks 6. The soft and elastic characteristics of the sponge blocks 6 reduce the friction between the pull rope 103 and the second hollow rod 13, can effectively protect the pull rope 103 from wear, can reduce the problem of breakage of the pull rope 103 caused by wear during use, can effectively increase the integrity and reliability of the pull rope 103, make the pull rope 103 move more smoothly, and can effectively control the moving position of the pull rope 103 to keep the pull rope 103 stable and accurate during use.

[0029] As Figure 2 shown, an elastic pad 7 is fixedly connected to the side wall of the clamping plate 19; the elastic pad 7 is fixedly connected to the side away from the through hole 100; an elastic pad 7 is fixedly connected to the side wall of the positioning block 102; during operation, when the bearing is fixed, the elastic pad 7 is in contact with the surface of the bearing. The elastic pad 7 can effectively reduce the vibration generated during the machining of the bearing, effectively improve the stability and reliability of the bearing, effectively absorb the impact generated during the machining of the bearing, reduce the damage caused by the impact during the machining of the bearing, and can effectively reduce the noise generated during the machining of the bearing, effectively increasing the comfort of the working environment.

[0030] During operation, place the middle part of the bearing into one end of the second hollow rod 13, so that the bearing is in the middle of the two clamping plates 19. After energizing the electric push rod 11, turn it on to make the output end of the electric push rod 11 stretch. When the electric push rod 11 stretches, the pull rope 103 becomes slack, and the pull rope 103 no longer pulls the positioning block 102. The positioning block 102 moves towards the bearing position elastically through the second spring 101, so that the positioning block 102 pushes and fixes the bearing. When the output end of the electric push rod 11 passes through the baffle 12 and contacts and pushes the sliding plate 15, the sliding plate 15 slides inside the pull rope 103. During the movement of the sliding plate 15, the two clamping plates 19 are supported through the connecting rod 16, so that the two clamping plates 19 are in close contact with the inside of the bearing and hold it up, fixing the bearing in the middle of the two clamping plates 19. At the same time, the first elastic telescopic rod 17 and the first spring 18 are elastically stretched as the clamping plates 19 are held up. There is a torsion spring at the connection between the connecting rod 16 and the clamping plate 19. After the bearing processing is completed, control the electric push rod 11 to contract. At the same time, the connecting rod 16 makes the sliding plate 15 reset through the torsion spring, and the clamping plate 19 resets through the first elastic telescopic rod 17 and the first spring 18. At the same time, the output end of the electric push rod 11 pulls the pull rope 103, making the positioning block 102 move away from the bearing position, and then rotate the bearing to process other positions. When the bearing is placed in the middle of the clamping plate 19 and clamped by the movement of the positioning block 102, the middle part of the bearing first contacts the pulley 22. The pulley 22 in contact with the middle part of the bearing is elastically contracted through the second elastic telescopic rod 21 under the pressure of the bearing, so that the pulley 22 moves into the first groove 2 and retracts. When the bearing is removed, the second elastic telescopic rod 21 resets the pulley 22 elastically. During the process of the electric push rod 11 moving and stretching to clamp the bearing with the positioning block 102, the pull rope 103 is in a slack state, and at the same time, the wire wheel 31 winds the slack pull rope 103. After the bearing is fixed, rotate the exhaust pipe 41 through the hinge shaft 42 to adjust the angle of the end of the exhaust pipe 41. After energizing and turning on the air pump 4, make the air flow into the middle of the exhaust pipe 41, and then discharge the air flow from the end of the exhaust pipe 41 to the designated position. When the bearing is placed and fixed in the middle of the clamping plate 19, the brush bristles 54 are attached to the surface of the bearing. When the bearing is larger in size, it presses on multiple groups of brush bristles 54. When the brush bristles 54 are under pressure, the sliding rod 52 slides in the chute 5 through the support rod 53, and at the same time, the third spring 51 is elastically stretched. After the bearing processing is completed, rotate the bearing, and clean the surface of the bearing through the brush bristles 54. During the movement of the pull rope 103, the sponge block 6 makes the end of the second hollow rod 13 contact the pull rope 103. When the bearing is fixed, it is attached to the surface of the bearing through the elastic pad 7.
