Bearings are usually composed of inner rings, outer rings, rolling elements and cages. The main function of bearings is to support mechanical rotating bodies, reduce friction resistance during their movement, and ensure their rotation accuracy. The inner and outer rings of bearings can be collectively referred to as bearing rings. The inner ring is used to cooperate with the rotating shaft, and the outer ring is used to cooperate with the bearing seat or housing. The end face of the bearing ring needs to be polished during the processing. After the existing bearing ring end face polishing device (such as an automatic end face polishing device for a bearing ring disclosed in application number 202123078932.2) completes the polishing of the end face of the bearing ring, it is necessary to stop the machine, remove the polished bearing ring, and then install the next bearing ring that needs to be polished. Since the time spent on taking and placing the bearing ring cannot be fully utilized to polish the next bearing ring, the polishing efficiency of the end face of the bearing ring is low, which is not conducive to batch polishing of the end face of the bearing ring.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The utility model provides a bearing ring end surface grinding device, the structure of which is as follows: Figure 1 and Figure 2As shown, it includes at least two placement troughs 100, a grinding mechanism 200, at least two pressing mechanisms 300 and a driving mechanism 400. The placement trough 100 has a placement groove 110 formed on its upper surface for horizontally placing the bearing ring; the grinding mechanism 200 is used to grind the upper end surface of the bearing ring; each of the pressing mechanisms 300 is correspondingly connected to each of the placement troughs 100 for pressing or loosening the bearing ring in the placement trough 100; the driving mechanism 400 is connected to each of the placement troughs 100 for driving each of the placement troughs 100 to rotate synchronously in a horizontal plane so that each of the placement troughs 100 arrives directly below the grinding mechanism 200 in turn.

[0024] When in use, the bearing rings of the end faces to be polished are placed in the placement grooves 110 in turn, and the pressing mechanisms 300 are controlled so that the pressing mechanisms 300 can press against the bearing rings in the placement grooves 100. Then, the driving mechanisms 400 are controlled so that the driving mechanisms 400 can drive the placement grooves 100 to rotate synchronously in the horizontal plane, so that the placement grooves 100 are placed directly below the polishing mechanisms 200 in turn. The grinding mechanism 200 can grind the upper end surface of the bearing ring. When the grinding mechanism 200 grinds the upper end surface of the bearing ring in the placement groove 100 directly below it, the bearing rings in other placement grooves 100 can be taken out or bearing rings can be placed in other placement grooves 100. The time spent on taking and placing the bearing rings can be fully utilized to grind other bearing rings, thereby improving the low grinding efficiency of the end surfaces of the bearing rings, which is conducive to batch grinding of the end surfaces of the bearing rings.

[0025] As a preferred embodiment, please refer to Figure 1 The width of the placement groove 110 is equal to the diameter of a single bearing ring, and the bearing ring can be positioned laterally via two opposite side walls in the length direction of the placement groove 110 .

[0026] As a preferred embodiment, please refer to Figure 1, one side wall of the placement slot 110 in the width direction is open, and the pressing mechanism 300 includes a pressing block 310 and an elastic member 320. The pressing block 310 is arranged at the opening of the placement slot 110, and the middle position of the pressing block 310 is hinged to the placement slot body 100 via a pin shaft. One end of the elastic member 320 is fixedly connected to the placement slot body 100, and the other end of the elastic member 320 is fixedly connected to the upper end of the pressing block 310, so that the inner side wall of the upper end of the pressing block 310 presses against the bearing ring, pushing the pressing block 310 so that the upper end of the pressing block 310 rotates in a direction away from the placement slot body 100, and in this process During the grinding process, the elastic member 320 is in a stretched state and accumulates stretching elastic potential energy. The bearing ring with the end face to be polished is placed in the placement groove 110, and the clamping block 310 is released. The elastic member 320 releases the stretching elastic potential energy, so that the upper end of the clamping block 310 rotates toward the direction close to the placement groove body 100, and the inner side wall of the upper end of the clamping block 310 presses against the bearing ring to fix the bearing ring. Since the existing clamping mechanism generally requires a driving member to drive the clamping member to clamp or release the bearing ring, the clamping mechanism 300 does not need to set an additional driving member, and is manually operated, which is more convenient and reduces the fixing cost of the bearing ring.

[0027] As a preferred embodiment, please refer to Figure 1 When the inner side wall of the pressing block 310 presses against the bearing ring, the pressing block 310 is in a vertical state, and the distance between the inner side wall of the pressing block 310 and the other side wall of the placement groove 110 in the width direction is equal to the diameter of at least one bearing ring. The bearing ring is fixed by the inner side wall of the placement groove 110 in the width direction and the inner side wall of the pressing block 310 and the bearing ring. The distance between the inner side wall of the pressing block 310 and the other side wall of the placement groove 110 in the width direction is equal to the diameter of a bearing ring, and a bearing ring is placed in the placement groove 110. The distance between the inner side wall of the pressing block 310 and the other side wall of the placement groove 110 in the width direction is equal to the diameter of several bearing rings, and a corresponding number of bearing rings are placed in the placement groove 110.

[0028] As a preferred embodiment, please refer to Figure 1 The elastic member 320 includes two springs 321, and the two springs 321 are relatively arranged on both sides of the placement groove body 100 along the length direction of the placement groove 110. One end of the two springs 321 is respectively fixed to the outer side wall of the corresponding placement groove body 100 in the length direction. Two springs 321 are set, and the tensile force of the two springs 321 can make the inner side wall of the upper end of the clamping block 310 clamp against the bearing ring, thereby improving the clamping strength against the bearing ring.

[0029] As a preferred embodiment, please refer to Figure 1 The clamping mechanism 300 also includes two fixed shafts 330, which are opposite to and horizontally arranged on both sides of the clamping block 310, and correspond one to one with the two springs 321. One end of the two fixed shafts 330 is fixedly connected to the clamping block 310, and the other ends of the two springs 321 are respectively fixedly connected to the corresponding fixed shafts 330. The other end of the spring 321 is fixedly connected to the clamping block 310 by being fixed to the fixed shaft 330.

[0030] As a preferred embodiment, please refer to Figure 2 The bottom of the placement trough body 100 is provided with a feed opening 120 extending along the length direction of the placement trough body 100, and the feed opening 120 is communicated with the placement trough 110. The abutting mechanism 300 also includes an ejector rod 340, which is arranged in the feed opening 120 and is perpendicular to the abutting block 310. One end of the ejector rod 340 is fixedly connected to the inner side wall of the abutting block 310, and the ejector rod 340 is used to abut against the lower end surface of the bearing sleeve end. , so as to eject the bearing ring in the placement groove 110. In order to ensure the fixing effect of the bearing ring, the distance between the upper surface of the bearing ring and the upper surface of the placement groove 110 is small, which is inconvenient when taking out the bearing ring. When pushing the clamping block 310 so that the upper end of the clamping block 310 rotates in the direction away from the placement groove body 100, the ejection rod 340 will rotate upward and eject the bearing ring, which can reduce the time spent on taking out the bearing ring.

[0031] As a preferred embodiment, please refer to Figure 1 When the inner wall of the clamping block 310 is in a vertical state, the upper surface of the ejector rod 340 is flush with or lower than the bottom of the placement groove 110, so as to avoid the ejector rod 340 interfering with the placement of the bearing ring, so that the bearing ring can be placed horizontally in the placement groove body 100.

[0032] As a preferred embodiment, please refer to Figure 1 The driving mechanism 400 includes a rotating table 410 and a first rotating driving member 420. Each of the placement slots 100 is fixedly arranged on the side of the rotating table 410 along the circumferential direction. The output shaft of the first rotating driving member 420 is fixedly connected to the rotating table 410 for driving the rotating table 410 to rotate. By manipulating the first rotating driving member 420, the first rotating driving member 420 can drive the rotating table 410 to rotate, thereby driving each of the placement slots 100 to rotate synchronously.

[0033] As a preferred embodiment, please refer to Figure 1The bearing ring end surface grinding device also includes a frame 500, the rotating table 410 is vertically arranged, the lower end of the rotating table 410 is rotatably installed on the frame 500, the output shaft of the first rotating driving member 420 is fixedly connected to the lower end of the rotating table 410, and the frame 500 is used to support the rotating table 410 and the first rotating driving member 420.

[0034] As a preferred embodiment, please refer to Figure 1 and Figure 2 The grinding mechanism 200 includes a moving frame 210, a grinding wheel 220, a second rotating driving member 230 and a telescopic driving member 240. The moving frame 210 is slidably mounted on the frame 500. The second rotating driving member 230 is fixed to the moving frame 210. The output end of the second rotating driving member 230 is fixedly connected to the grinding wheel 220 for driving the grinding wheel 220 to rotate. The telescopic driving member 240 is fixed to the frame 500. The output end of the telescopic driving member 240 is fixedly connected to the moving frame 210 for driving the moving frame 2 10 moves up and down. When there are multiple bearing rings placed in the placement groove 110, the diameter of the grinding wheel 220 must be greater than or equal to the sum of the diameters of the multiple bearing rings. By manipulating the telescopic driving member 240, the telescopic driving member 240 can drive the movable frame 210 to move downward until the lower surface of the grinding wheel 220 abuts against the upper end surface of the bearing ring, and then by manipulating the second rotating driving member 230, the second rotating driving member 230 can drive the grinding wheel 220 to rotate, thereby grinding the upper end surface of the bearing ring.

[0035] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the utility model is described in detail:

[0036] When in use, the bearing ring of the end surface to be polished is placed in each of the placement grooves 110 in turn, and the clamping block 310 is pushed so that the upper end of the clamping block 310 rotates in the direction away from the placement groove body 100. During this process, the elastic member 320 is in a stretched state and accumulates stretching elastic potential energy. The bearing ring of the end surface to be polished is placed in the placement groove 110, and the clamping block 310 is released. The elastic member 320 releases the stretching elastic potential energy, so that the upper end of the clamping block 310 rotates in the direction close to the placement groove body 100. The inner side wall of the upper end of the clamping block 310 presses against the bearing ring to fix the bearing ring. Then, by manipulating the first rotating driving member 420, the first rotating driving member 420 can drive the rotating table 410 to rotate, thereby driving each of the placement groove bodies 100 to rotate synchronously, so that each of the placement groove bodies 10 0 arrives directly below the grinding mechanism 200 in turn, and then controls the telescopic driving member 240 so that the telescopic driving member 240 can drive the moving frame 210 to move downward until the lower surface of the grinding wheel 220 abuts against the upper end surface of the bearing ring, and then controls the second rotating driving member 230 so that the second rotating driving member 230 can drive the grinding wheel 220 to rotate, thereby grinding the upper end surface of the bearing ring. When the grinding mechanism 200 grinds the upper end surface of the bearing ring in the placement groove 110 directly below it, the bearing rings in other placement grooves 110 can be taken out or placed into other placement grooves 110, so that the time spent on taking and placing the bearing rings can be fully utilized to grind other bearing rings, thereby improving the grinding efficiency of the end surface of the bearing ring, which is conducive to batch grinding of the end surface of the bearing ring.

[0037] The bearing ring end surface grinding device provided by the utility model has the following beneficial effects:

[0038] (1) Since the existing clamping mechanism generally needs to be provided with a driving member to drive the clamping member to clamp or loosen the bearing ring, the clamping mechanism 300 does not need to be provided with an additional driving member and can be operated manually, which is more convenient and also reduces the fixing cost of the bearing ring;

[0039] (2) In order to ensure the fixing effect of the bearing ring, the distance between the upper surface of the bearing ring and the upper surface of the placement groove 110 is small, which makes it inconvenient to remove the bearing ring. When the pressing block 310 is pushed so that the upper end of the pressing block 310 rotates in a direction away from the placement groove body 100, the ejection rod 340 rotates upward and ejects the bearing ring, which can reduce the time spent on removing the bearing ring.

[0040] (3) The time spent on taking and placing the bearing rings can be fully utilized to grind other bearing rings, thereby improving the grinding efficiency of the end faces of the bearing rings, which is low and is conducive to batch grinding of the end faces of the bearing rings.
