Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to an automatic grinding device for a bearing outer ring. Background Art

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during transmission. According to the different friction properties of the moving elements, bearings can be divided into rolling bearings and sliding bearings.

[0003] The bearing is mainly composed of the inner ring, outer ring, balls (rollers) and cage. In order to ensure that the center position of the shaft does not change with the rotation of the shaft during operation, it needs to be fixed with a bearing. Therefore, during the manufacturing process of the bearing, the cylindricality requirements of the outer circumference of the outer ring and the inner circumference of the inner ring are relatively high.

[0004] In the prior art, the inner circumference of the inner ring of the bearing is polished by a special grinding device, but the outer circumference of the outer ring of the bearing is not polished by a special device. In addition, before grinding the bearing, the prior art usually needs to control the distance between the bearings during transportation, so that when one of the bearings is processed (the transmission needs to be stopped during processing and the processing needs to be completed), the other bearing will not be affected (when processing the bearing, the bearing may need to be rotated, and the grinding debris will fall onto another unprocessed bearing, affecting its processing quality). Or before grinding the bearing, in order to speed up production efficiency and maintain a close fit between the bearings during transportation, this method requires an additional robotic arm to extract a bearing and process it separately. Therefore, it is difficult for the existing grinding device to achieve economical and efficient grinding. Summary of the invention

[0005] One of the purposes of the present invention is to solve the problem that the grinding device in the prior art is difficult to achieve economical and efficient grinding.

[0006] A second object of the present invention is to provide a grinding method.

[0007] To achieve one of the above-mentioned purposes, the present invention adopts the following technical scheme: an automatic grinding device for the outer ring of a bearing, which includes: a first telescopic structure; a push plate, the push plate is connected to the first telescopic structure, and the push plate has: a transmission rod on both sides, and the transmission rod can move up and down on the push plate; a conveying table, the conveying table is arranged at the rear end of the first telescopic structure, the push plate is located on the conveying table, and the conveying table has: a baffle on both sides, the baffle has: an arc-shaped through groove, and the transmission rod passes through the arc-shaped through groove; a synchronous clamp, the synchronous clamp is arranged on both sides of the conveying table, and the synchronous clamp has: a swivel arm, the swivel arm is movably connected to the side end of the synchronous clamp, and the swivel arm has: a force groove, the force groove is semi-open, and the transmission rod passes through After passing through the arc-shaped through groove, it is connected to the force-bearing groove; a gear, the gear is installed in the synchronous clamp, and the gear is connected to the rotating arm; a passive rod, teeth are distributed on the passive rod, and the teeth mesh with the gear; a movable rod, the movable rod is inclined relative to the passive rod, and one end of the movable rod is movably connected to the passive rod; a clamping member, the clamping member is perpendicular to the conveying platform, and the clamping member is movably connected to the other end of the movable rod; a positioning platform, the positioning platform is arranged at the rear end of the synchronous clamp, and the positioning platform has: a first slide groove, the synchronous clamp is connected to the first slide groove; a support auxiliary, the support auxiliary is installed at the rear end of the conveying platform, and the height of the support auxiliary is lower than the conveying platform; a driving clamp, the driving clamp is arranged above the support auxiliary.

During the rotation of the rotating arm, the gear is driven to rotate and drive the passive rod to move, so that the active rod pushes the clamping member to extend and clamp the bearing. The first telescopic structure is started again to drive the push plate to move backward, push the bearing that falls on the push plate, and push the rotating arm through the transmission rod (the rotating arm is tightly connected and not easily pushed to rotate), drive the synchronous clamp to slide backward in the first slide groove of the positioning platform, insert the clamped outer ring of the bearing into the driving clamp, and make the outer periphery of the outer ring of the bearing fit with the supporting auxiliary device.

[0011] When the clamping member releases its clamping of the bearing outer ring and the bearing outer ring on the conveying platform is not pushed to the specified position by the push plate, the first telescopic structure continues to drive the push plate to push the bearing outer ring to the specified position. At this time, the transmission rod on the push plate moves along the linear slide groove.

[0015] Further, in an embodiment of the present invention, the support auxiliary device is an arc-shaped structure, which includes: a ball; a chip removal ring, which is elastic and installed in the support auxiliary device, and the chip removal ring has: a mounting port, in which the ball is placed; a chip removal port, which is formed by notches opened at the left and right ends of the mounting port; and a chip discharge port, which is arranged at the side end of the support auxiliary device, and the chip discharge port is connected to the chip discharge port.

[0016] When the outer ring of the bearing is being ground, the balls on the support auxiliary device move along the rotation direction of the outer ring of the bearing, and part of the chips generated by the grinding are concentrated in the chip discharge port along the rotation of the balls, so that the support auxiliary device can discharge the chips from the chip discharge port.

[0017] Furthermore, in an embodiment of the present invention, the support assistant also includes: a slider, which is installed at the lower end of the support assistant and can slide left and right; a support rod, which is movably connected to the slider; and a two-way telescopic structure, which is connected to the slider.

[0018] Furthermore, in an embodiment of the present invention, the automatic grinding device for the outer ring of the bearing further comprises:

[0019] A filtered water tank, the filtered water tank is located directly below the supporting auxiliary device, and the lower end of the supporting rod is movably connected to the four corners of the filtered water tank; a water nozzle, the water nozzle is arranged above the driving clamp, and the water nozzle is connected to the filtered water tank.

[0020] Furthermore, in an embodiment of the present invention, the automatic grinding device for the outer ring of the bearing also includes: a fixed table, the fixed table is arranged at the rear end of the supporting auxiliary device, and one end of the driving clamp is movably connected to the fixed table; a conveyor belt, the conveyor belt is arranged below the fixed table; the driving clamp includes: a rotating drum, the rotating drum is rotatably connected to the driving clamp; a top piece, the top piece is distributed on the rotating drum; a connecting rod, the connecting rod is arranged on the rotating drum, the connecting rod is connected to the top piece; a driving block, the driving block is telescopically connected to the connecting drum A connecting rod; a first spring, the first spring is arranged between the driving block and the connecting rod; a power body, the power body is fixed on the driving clamp, the power end of the power body extends into the rotating drum, and the power body is coaxial with the rotating drum; an arc body, the arc bodies are evenly distributed on the power body, there are gaps between the arc bodies, and the driving block is located in the gap; the driving clamp also includes: a lifting ear, the lifting ear is installed on the driving clamp; a second spring, the second spring is connected to the fixed platform, and the second spring has: a hook, the hook is connected to the lifting ear.

[0021] The process of driving the clamp to support the inner wall of the outer ring of the bearing is: the arc body is driven to rotate by the power body, so that the arc surface of the arc body presses the driving block to move outward, thereby driving the top piece on the connecting rod to extend to press the inner wall of the outer ring of the bearing. At this time, the arc body continues to push the driving block to move, thereby causing the driving block to extend into the connecting rod to compress the first spring, so that the outer ring of the bearing is fixedly clamped by the top piece.

[0022] During grinding, the power body drives the outer ring of the bearing to rotate, thereby comprehensively grinding the outer surface of the outer ring of the bearing.

[0023] After grinding is completed, the two-way telescopic structure is started to pull the slider to move relative to each other, so that the support rod is offset to the middle of the support auxiliary device, thereby lowering the height of the support auxiliary device. At this time, the second spring on the driving clamp cannot withstand the driving clamp that clamps the outer ring of the bearing, so that the driving clamp rotates downward, so that the outer ring of the bearing faces the conveyor belt, and then the arc body is driven by the power body to rotate in the opposite direction, so that the driving block is reset. At this time, the compressed first spring keeps the support connecting rod and the top piece while resetting, gradually reducing the clamping force of the top piece on the outer ring of the bearing, until the first spring no longer pushes the connecting rod and the top piece to press against the inner wall of the outer ring of the bearing, so that the outer ring of the bearing can slowly fall onto the conveyor belt by gravity.

[0024] The beneficial effects of the present invention are:

[0025] The present invention not only controls the frequency of the bearing outer ring falling onto the conveying platform by squeezing the rotating arm forward through the first telescopic structure to ensure the number of bearing outer rings on the conveying platform, but also controls the clamping member to clamp the bearing outer ring at the rear end of the conveying platform, and squeezes the rotating arm backward through the first telescopic structure, not only can the clamped bearing outer ring be inserted into the driving clamp for fixing and the bearing outer ring on the conveying platform be pushed into a specified position, but also can reversely rotate by squeezing the rotating arm, so that the clamping member releases the bearing outer ring, and then the first telescopic structure drives the clamping member to reset, so that the external grinding device can grind the entire outer surface of the bearing outer ring. Therefore, the present invention can not only ensure the close fitting transportation between the bearing outer rings, but also does not require an additional clamping mechanism to take out the fitted bearing outer ring for grinding, has strong synchronization, and realizes economical and efficient grinding of the bearing outer ring.

[0026] To achieve the second purpose above, the present invention adopts the following technical solution: a grinding method, comprising the following steps:

[0027] Feeding, starting the first telescopic structure to drive the push plate forward, so that the transmission rod squeezes the rotating arm on the synchronous clamper, and under the blocking of the front end wall of the first slide groove of the positioning platform, the transmission rod squeezes the rotating arm, causing the rotating arm to rotate, so that the transmission rod and the push plate move to the front end position, and then the outer ring of the bearing falls into the position of the conveying platform before the push plate moves;

[0028] During the clamping and rotation of the rotating arm, the gear is driven to rotate and drive the passive rod to move, so that the active rod pushes the clamping part to extend and contact and clamp the bearing;

[0030] Fixing and resetting, by driving the clamper to support the inner wall of the clamped bearing outer ring, and then continue to push the synchronous clamper to move backward through the first telescopic structure. At this time, the synchronous clamper is blocked by the rear end wall of the first slide slot of the positioning platform, and the rotating arm rotates in the opposite direction under the extrusion of the transmission rod, thereby driving the gear to drive the passive rod, the active rod, and the clamping member to reset, thereby making the clamping member release the clamping of the bearing outer ring. At the same time, the bearing outer ring on the conveying platform is pushed to the specified position on the push plate;

[0031] Returning, pushing the synchronous clamp forward through the first telescopic structure to return to the initial position;

[0032] Grinding: Grinding the outer ring of the bearing fixed by the driven clamp and supported by the supporting auxiliary device through an external grinding device.

[0033] Furthermore, in an embodiment of the present invention, when the clamping member releases its clamping of the bearing outer ring and the bearing outer ring on the conveying platform is not pushed to the specified position by the push plate, the first telescopic structure continues to drive the push plate to push the bearing outer ring to the specified position, and at this time, the transmission rod on the push plate moves along the linear slide groove.

[0034] Furthermore, in an embodiment of the present invention, the process of driving the clamp to support the inner wall of the outer ring of the bearing is: the arc body is driven to rotate by the power body, so that the arc surface of the arc body presses the driving block to move outward, thereby driving the top piece on the connecting rod to extend and press the inner wall of the outer ring of the bearing. At this time, the arc body continues to push the driving block to move, thereby causing the driving block to extend into the connecting rod to compress the first spring, so that the outer ring of the bearing is fixedly clamped by the top piece.

[0035] Furthermore, in the embodiment of the present invention, during grinding, the power body drives the outer ring of the bearing to rotate, thereby comprehensively grinding the outer surface of the outer ring of the bearing.

[0037] Furthermore, in an embodiment of the present invention, after grinding is completed, the two-way telescopic structure is started to pull the slider to move relative to each other, so that the support rod is offset toward the middle of the support auxiliary device, thereby lowering the height of the support auxiliary device. At this time, the second spring on the driving clamp cannot withstand the driving clamp that clamps the outer ring of the bearing, thereby causing the driving clamp to rotate downward, so that the outer ring of the bearing is facing the conveyor belt, and then the arc body is driven by the power body to rotate in the opposite direction, so that the driving block is reset. At this time, the compressed first spring keeps the support connecting rod and the top piece while resetting, gradually reducing the clamping force of the top piece on the outer ring of the bearing until the first spring no longer pushes the connecting rod and the top piece to press against the inner wall of the outer ring of the bearing, so that the outer ring of the bearing can slowly fall onto the conveyor belt by gravity.

At this time, the synchronous clamper 4 is blocked by the rear end wall of the first slide groove 91 of the positioning platform 9, and the rotating arm 5 rotates in the opposite direction under the pressure of the transmission rod 21, thereby driving the gear 52 to drive the passive rod 6, the movable rod 7, and the clamping member 8 to reset, thereby allowing the clamping member 8 to release the clamping of the outer ring of the bearing. At the same time, the outer ring of the bearing on the conveying platform 3 is pushed to the specified position on the pushing plate 2.

[0107] Preferably, when the clamping member 8 releases its clamping on the outer ring of the bearing and the outer ring of the bearing on the conveying table 3 has not been pushed to the specified position by the pushing plate 2, the first telescopic structure 1 continues to drive the pushing plate 2 to push the outer ring of the bearing to the specified position. At this time, the transmission rod 21 on the pushing plate 2 moves along the linear slide groove 42.

[0108] Preferably, the process of driving the clamp 13 to support the inner wall of the outer ring of the bearing is: driving the arc body 137 to rotate through the power body 136, so that the arc surface of the arc body 137 presses against the driving block 134 and moves outward, thereby driving the top piece 132 on the connecting rod 133 to extend and press against the inner wall of the outer ring of the bearing. At this time, the arc body 137 continues to push the driving block 134 to move, thereby causing the driving block 134 to extend into the connecting rod 133 to compress the first spring 135, so that the outer ring of the bearing is fixedly clamped by the top piece 132.

[0109] More preferably, during grinding, the power body 136 drives the outer ring of the bearing to rotate, thereby comprehensively grinding the outer surface of the outer ring of the bearing.

[0111] More preferably, after the grinding is completed, the two-way telescopic structure 107 is started to pull the slider 106 to move relative to each other, so that the support rod 11 is offset to the middle of the support auxiliary device 10, thereby reducing the height of the support auxiliary device 10. At this time, the second spring 139 on the driving clamp 13 cannot withstand the driving clamp 13 that clamps the outer ring of the bearing, so that the driving clamp 13 rotates downward, so that the outer ring of the bearing faces the conveyor belt 16, and then the arc body 137 is driven by the power body 136 to rotate in the opposite direction, so that the driving block 134 is reset. At this time, the compressed first spring 135 keeps the support connecting rod 133 and the top piece 132 reset, and gradually reduces the clamping force of the top piece 132 on the outer ring of the bearing until the first spring 135 no longer pushes the connecting rod 133 and the top piece 132 to press against the inner wall of the outer ring of the bearing, so that the outer ring of the bearing can slowly fall onto the conveyor belt 16 by gravity.
