Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of bearing polishing, and particularly relates to an automatic bearing ring polishing device. BACKGROUND

[0002] Bearing is a kind of part commonly used in mechanical devices, and is widely used in household appliances, textile machinery, printing machinery, medical machinery, precision machine tools and other equipment. The bearing is usually composed of an inner ring, an outer ring, a rolling body and a retainer. The main function of the bearing is to support the rotating body of the machine, reduce the frictional resistance in the movement process, and ensure the rotation accuracy. The inner ring and the outer ring of the bearing can be collectively referred to as bearing rings. The inner ring is used for cooperation with the rotating shaft, and the outer ring is used for cooperation with the bearing seat or the shell.

[0003] The bearing ring is processed from an annular blank. The surface of the blank has burrs, and the initial size does not meet the design requirements.

In the prior art, the inner hole and the outer circle of the bearing ring are polished separately, and two polishing devices are needed. Although most of the polishing devices have realized automatic polishing, the transfer of the bearing ring between the two polishing devices and the feeding and discharging still need manual operation, and the degree of automation still needs to be improved.

[0068] Compared with the prior art, the bearing ring automatic polishing equipment 1 provided by the embodiment of the present application has the following beneficial effects:

[0069] The bearing ring automatic polishing equipment 1 provided by the embodiment of the application comprises a supporting assembly 10, a first polishing assembly 20, a second polishing assembly 30, a first transfer assembly 40 and a second transfer assembly 50. When in use, a conveying belt 12 is used to transport the bearing ring to be polished to a first feeding position 111, the first transfer assembly 40 is used to transfer the bearing ring to the first polishing assembly 20, a plurality of first polishing assemblies 20 are used to polish the inner hole or the outer circle in turn in multiple processes, then the first transfer assembly 40 is used to transfer the bearing ring whose inner hole is polished to a first discharging position 112, and the conveying belt 12 is used to transport the bearing ring from the first discharging position 112 to a second feeding position 113. The second transfer assembly 50 is used to transfer the bearing ring to the second polishing assembly 30, a plurality of second polishing assemblies 30 are used to polish the outer circle or the inner hole in turn in multiple processes, then the second transfer assembly 50 is used to transfer the bearing ring whose outer circle is polished to a second discharging position 114, and the conveying belt 12 is used to transport the bearing ring whose inner hole and outer circle are polished to a subsequent working position.

[0070] The bearing ring automatic polishing equipment 1 provided by the embodiment of the application realizes the automatic conveying of the bearing ring from the feeding end to the first feeding position 111, from the first discharging position 112 to the second feeding position 113 and from the second discharging position 114 to the discharging end through the conveying belt 12, and automatically completes the polishing of the inner hole and the outer circle of the bearing ring in cooperation with the first polishing assembly 20, the second polishing assembly 30, the first transfer assembly 40 and the second transfer assembly 50. The inner hole polishing and the outer circle polishing are combined into one in the application, the structure is more compact, the automatic feeding and discharging are realized through the conveying belt 12, the first transfer assembly 40 and the second transfer assembly 50, the manual labor is more saved, and the automation degree is higher.

[0071] The supporting assembly 10 in the embodiment of the application comprises a base 11 and a conveying belt 12. The base 11 is used to provide stable support for each part mounted thereon. The base 11 can be formed by welding a steel plate and a shaped steel or obtained by casting iron. The base 11 is provided with the first feeding position 111, the first discharging position 112, the second feeding position 113 and the second discharging position 114. The conveying belt 12 is horizontally arranged and can drive the bearing ring to pass through the first feeding position 111, the first discharging position 112, the second feeding position 113 and the second discharging position 114 in turn during operation, thereby completing the feeding, discharging and automatic transfer of the bearing ring at the discharging end of the first polishing assembly 20 and the feeding end of the second polishing assembly 30.

[0072] The conveying belt 12 can convey one or more bearing rings at the same time. When the conveying belt 12 conveys only one bearing ring at a time, in order to ensure that the first transfer assembly 40 can accurately grasp the bearing ring to complete the feeding, the conveying belt 12 stops when the conveying belt 12 moves the bearing ring to the first feeding position 111. After the bearing ring is stationary at the first feeding position 111, the first transfer assembly 40 is actuated to grasp the bearing ring at the first feeding position 111 and transfer it to the first polishing assembly 20.

[0073] When the conveying belt 12 conveys multiple bearing rings at a time, an intercepting structure can be arranged at the first feeding position 111 and the second feeding position 113 to block the bearing rings on the conveying belt 12, so as to ensure that the first transfer assembly 40 or the second transfer assembly 50 can accurately grasp the bearing ring to be polished.

[0074] The conveying belt 12 can be a belt conveyor, a chain plate conveyor, etc. The width of the conveying belt 12 is slightly larger than the width of the bearing ring to be polished, so as to prevent the bearing ring from shaking too much on the conveying belt 12 and deviating from the position while ensuring normal conveying of the bearing ring.

[0075] One of the first polishing assembly 20 and the second polishing assembly 30 is used for polishing the inner hole of the bearing ring, and the other is used for polishing the outer circle of the bearing ring. By arranging multiple first polishing assemblies 20 and multiple second polishing assemblies 30, rough to fine polishing of the surface of the bearing ring can be achieved. In use, the outer circle can be polished first, and then the inner hole can be polished, or the inner hole can be polished first, and then the outer circle can be polished.

[0076] It should be noted that the granularity, material, size, etc. of the polishing head can be set by those skilled in the art according to actual needs, and are not limited specifically herein.

[0077] The first feeding position 111, the multiple first polishing assemblies 20, and the first discharging position 112 are arranged along the circumference of the first ring, so as to facilitate the first transfer assembly 40 to grasp and transfer the bearing ring between the multiple polishing stations. The second feeding position 113, the multiple second polishing assemblies 30, and the second discharging position 114 are arranged along the circumference of the second ring, so as to facilitate the second transfer assembly 50 to grasp and transfer the bearing ring between the multiple polishing stations.

[0078] The first feeding position 111, the plurality of first polishing assemblies 20, and the first discharging position 112 are evenly arranged along a first ring line. The second feeding position 113, the plurality of second polishing assemblies 30, and the second discharging position 114 are evenly arranged along a second ring line concentric with the first ring line, and the diameter of the second ring line is greater than that of the first ring line. In this way, on the one hand, the structure is more compact, and the plurality of first polishing assemblies 20 and second polishing assemblies 30 can be arranged in a smaller space, and the space utilization rate is higher. On the other hand, the annular arrangement also facilitates the first transfer assembly 40 and the second transfer assembly 50 to transfer the bearing ring between the plurality of processes, and the transfer distance is short, and the transfer efficiency is high.

[0079] The first transfer assembly 40 and the second transfer assembly 50 can be a transfer robot or other devices or apparatuses capable of clamping and transferring the bearing ring in the prior art. Specifically, the first transfer assembly 40 and the second transfer assembly 50 can grasp and release the bearing ring by mechanical clamping, electromagnetic adsorption, vacuum adsorption, etc.

[0080] Referring to Figure 1 and Figure 4 In some possible embodiments, the conveying belt 12 includes a first conveying section 121, a second conveying section 122, and a return section 123. The first conveying section 121 is arranged on the base 11 in a preset horizontal direction, and sequentially passes through the first feeding position 111 and the first discharging position 112. The second conveying section 122 is arranged on the base 11 in a preset horizontal direction, and sequentially passes through the second feeding position 113 and the second discharging position 114. The conveying direction of the second conveying section 122 is opposite to that of the first conveying section 121. The return section 123 is connected between the first conveying section 121 and the second conveying section 122.

[0081] In the embodiment, the conveying belt 12 includes the first conveying section 121 and the second conveying section 122 arranged in a straight line, and the return section 123 connected between the first conveying section 121 and the second conveying section 122. The return section 123 is in a semicircular ring shape. The arrangement structure of the conveying belt 12 is simple, and the number of turns is small, which helps to stably convey the bearing ring on the conveying belt 12.

[0082] Referring to Figures 1 to 5 In some possible embodiments, the support assembly 10 further includes a first limiting block 13 and a second limiting block 14. The first limiting block 13 is arranged above the first conveying section 121 and has a first limiting groove 131. The opening direction of the first limiting groove 131 is opposite to the conveying direction of the first conveying section 121, and the first limiting groove 131 forms the first feeding position 111. The second limiting block 14 is arranged above the second conveying section 122 and has a second limiting groove 141. The opening direction of the second limiting groove 141 is opposite to the conveying direction of the second conveying section 122, and the second limiting groove 141 forms the second feeding position 113.

[0083] The first limiting block 13 and the second limiting block 14 in the embodiment are used to intercept and position the bearing ring, so as to be grabbed by the corresponding first transfer assembly 40 or the second transfer assembly 50. When the bearing ring moves to the first feeding position 111 along the conveying belt 12, the first limiting block 13 can intercept the bearing ring, which is blocked in the first limiting groove 131, and then the bearing ring is grabbed by the first transfer assembly 40. When the bearing ring moves to the second feeding position 113 along the conveying belt 12, the second limiting block 14 can intercept the bearing ring, which is blocked in the second limiting groove 141, and then the bearing ring is grabbed by the second transfer assembly 50.

[0084] Please refer to Figure 5 In some possible embodiments, the support assembly 10 further comprises a first limiting plate and a second limiting plate 15. The first limiting plate is arranged above the first conveying section 121 and located at the opening side of the first limiting groove 131, and the first limiting plate and the first limiting groove 131 form a first feeding passage for only one bearing ring to pass through. The second limiting plate 15 is arranged above the second conveying section 122 and located at the opening side of the second limiting groove 141, and the second limiting plate 15 and the second limiting groove 141 form a second feeding passage for only one bearing ring to pass through.

When multiple bearing rings are conveyed at the same time, the size of the first feeding passage and the second feeding passage can only allow one bearing ring to pass through, so that only one bearing ring can be grabbed at a time, and multiple grabbing is avoided.

[0086] Please refer to Figure 1 , Figure 3 and Figure 4 In some possible embodiments, the first transfer assembly 40 comprises a first rotating column 41, a plurality of first cantilever arms 42, and a plurality of first clamping mechanisms 43. The first rotating column 41 is rotatably arranged on the base 11 about a vertical axis and located at the center of the first ring line. The plurality of first cantilever arms 42 are arranged on the first rotating column 41 along the circumference and correspond to the first feeding position 111, the plurality of first polishing assemblies 20, and the first feeding position 112 one by one. The plurality of first clamping mechanisms 43 are arranged on the first cantilever arms 42 one by one and located above the corresponding first feeding position 111, the plurality of first polishing assemblies 20, and the first feeding position 112.

[0087] The first transfer assembly 40 in the embodiment includes a first rotating column 41, a plurality of first cantilevers 42, and a plurality of first clamping mechanisms 43. The first rotating column 41 is driven to rotate by a motor or a hydraulic motor. The plurality of first polishing assemblies 20 can polish respective bearing rings respectively.

The plurality of second cantilevers 52 are arranged on the second rotating column 51 along a circumferential direction and correspond to the second feeding station 113, the plurality of second polishing assemblies 30, and the second unloading station 114 one by one. The plurality of second clamping mechanisms 53 are arranged on the second cantilevers 52 one by one and located above the corresponding second feeding station 113, the plurality of second polishing assemblies 30, and the second unloading station 114.

[0089] The second transfer assembly 50 in the embodiment includes a second rotating column 51, a plurality of second cantilevers 52, and a plurality of second clamping mechanisms 53. The second rotating column 51 is driven to rotate by a motor or a hydraulic motor. The plurality of second polishing assemblies 30 can polish respective bearing rings respectively.

[0090] Please refer to Figure 1 and Figure 2 In some possible embodiments, the first clamping mechanisms 43 and the second clamping mechanisms 53 respectively include a vertically arranged lifting cylinder 431 and an electromagnetic chuck 432. The vertically arranged lifting cylinder 431 is arranged on the corresponding first cantilever 42 or second cantilever 52. The lifting end of the lifting cylinder 431 is arranged downward. The electromagnetic chuck 432 is arranged on the lifting end.

[0091] The first and second clamping mechanisms 43 and 53 have identical structures, comprising a lifting cylinder 431 and an electromagnetic suction cup 432, respectively. To grasp a bearing ring, the lifting end of the lifting cylinder 431 extends downward, energizing the electromagnetic suction cup 432 to generate a magnetic force that attracts the bearing ring. The lifting end of the lifting cylinder 431 then retracts upward to prevent collision or interference with other components during rotation. To release the bearing ring, the lifting end of the lifting cylinder 431 extends downward, deactivating the electromagnetic suction cup 432 and dissipating the electromagnetic force. The bearing ring is then securely placed in its desired polishing or transport position for the next step of polishing or transport.
