[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] Refer to the attached Figure 1 -Attached Figure 10, a new type of thrust bearing processing and grinding device, including a processing table 1, a support plate 2 is fixedly installed on the top of the processing table 1, and a support cylinder 3 is fixedly installed on the outer surface of the support plate 2. The movement of the support cylinder 3 is a closed structure, and a feed tray 4 is rotatably installed on the end of the closed end of the support cylinder 3. A plurality of placement grooves 5 are equidistantly opened in the circumferential direction of the outer surface of the feed tray 4 away from the support cylinder 3. A cover plate 6 is detachably installed on the outer surface of the feed tray 4 on one side of the placement groove 5 by screws. A vertical downward feeding rack 7 is fixedly installed on the outer surface of the top of the support plate 2, and the feeding rack 7 is adapted to the size of the placement groove 5. Equipped with a grinding mechanism, the outer surface of the feeding tray 4 near each placement slot 5 is penetrated with a through hole, and the outer surface of the feeding tray 4 near the through hole is installed with a positioning mechanism, the positioning mechanism includes two support rods 8 fixedly installed on the outer surface of the feeding tray 4 near the support plate 2, the two support rods 8 are fixedly installed with a T-shaped plate 12 on one end away from the feeding tray 4, the outer surfaces of the two support rods 8 are slidably installed with a movable plate 9, the outer surface of the movable plate 9 is rotatably installed with a positioning tube 10, the outer surface of the positioning tube 10 is fixedly installed with two limiting rings, and the movable plate 9 is installed between the two limiting rings; the positioning tube 10 can pass through the upper surface of the feeding tray 4 The through hole is set, and the end of the positioning tube 10 near the feed tray 4 is conical. A plurality of slide grooves are equidistantly penetrated through the outer periphery of the positioning tube 10 near the conical end. An L-shaped clamp 11 is slidably installed on the inner wall of each slide groove. A loose clamp assembly is installed between the T-plate 12 and the L-shaped clamp 11. A telescopic assembly is installed between the movable plate 9 and the support cylinder 3. The telescopic assembly includes a guide column 17 fixedly mounted on the outer surface of one side of the movable plate 9 near the support cylinder 3. A closed-loop guide groove 16 is provided on the outer periphery of the support cylinder 3. The expanded state of the closed-loop guide groove 16 is trapezoidal. The guide column 17 slides along the inner wall of the closed-loop guide groove 16. Dynamic installation, the closed-loop guide groove 16 is composed of an extended segment groove, a grinding segment groove, a retracted segment groove and an annular flat groove connected end to end. The grinding segment groove is set toward the grinding mechanism. The loosening assembly includes a fixed frame 13 fixedly mounted on the outer surface of the T-shaped plate 12. The fixed frame 13 is arranged inside the positioning tube 10. The outer surface of the fixed frame 13 away from the T-shaped plate 12 is evenly fixed in groups of two in the circumferential direction with multiple groups of guide frames 14 corresponding to the L-shaped clamping block 11. The multiple groups of guide frames 14 are arranged in a trumpet shape and tilted outward. The outer surface of the L-shaped clamping block 11 is fixedly mounted with a movable column 15, and the movable column 15 is slidably installed on the inner wall of the guide frame 14.

[0033] During use, the thrust bearing ring to be ground is placed in the feeding rack 7, and the thrust bearing ring will fall into the placement groove 5 at the top of the feeding tray 4. At this time, the feeding tray 4 is driven by the stepping motor 23 to drive the thrust bearing ring to rotate toward the grinding mechanism. While the feeding tray 4 rotates, the supporting rod 8 drives the movable plate 9, so that the guide column 17 installed on the movable plate 9 moves in the closed-loop guide groove 16 (the guide column 17 moves from the annular flat groove to the extending section groove and the grinding section groove in sequence), so that the guide column 17 can position the positioning tube through the movable plate 10. 10 is pushed toward the direction of the feed tray 4, so that the positioning tube 10 penetrates into the thrust bearing ring. At the same time, when the positioning tube 10 moves, it will drive the L-shaped clamping block 11 to move synchronously. Since the L-shaped clamping block 11 is movably installed with the inclined guide frame 14 through the movable column 15, when the positioning tube 10 moves toward the feed tray 4, the L-shaped clamping block 11 will extend outward, so that multiple L-shaped clamping blocks 11 can clamp the inner ring of the thrust bearing ring, so as to center the thrust bearing ring and prevent affecting the grinding accuracy during the subsequent thrust bearing ring grinding operation.

[0034] In this embodiment, an intermittent rotating mechanism is installed between the positioning tube 10 and the support tube 3. The intermittent rotating mechanism includes a transmission gear 19 sleeved on the outer surface of the positioning tube 10. The outer surface of the feed tray 4 close to the support plate 2 is fixedly mounted with a retaining frame 18 for axially limiting the transmission gear 19. The transmission gear 19 is rotatably mounted on the inner side of the retaining frame 18. The outer periphery of the support tube 3 is fixedly mounted with an incomplete gear ring 22 that intermittently meshes with the transmission gear 19. The locking teeth of the incomplete gear ring 22 correspond to the position of the grinding segment groove. A connecting component is installed between the transmission gear 19 and the positioning tube 10.

[0035] After the positioning of the thrust bearing ring is completed, as the feed plate 4 continues to rotate, the transmission gear 19 installed on the outer periphery of the positioning tube 10 will engage with the teeth of the incomplete gear ring 22, so that the transmission gear 19 can drive the positioning tube 10 to rotate through the transmission bar 20, so that the L-shaped clamp 11 installed on the positioning tube 10 drives the thrust bearing ring to rotate, so that the grinding belt 27 can grind the outer ring of the thrust bearing ring as a whole.

[0036] In this embodiment, the grinding mechanism includes an electric telescopic rod 24 fixedly mounted on the top of the processing table 1, and an arc-shaped grinding frame 25 is fixedly mounted on the telescopic end of the electric telescopic rod 24. Two support wheels 26 are installed inside the arc-shaped grinding frame 25 for rotation. The outer surfaces of the two support wheels 26 are provided with a grinding belt 27. The inner side of the arc-shaped grinding frame 25 is provided with an arc-shaped groove adapted to the grinding belt 27. The two sides of the grinding belt 27 are slidably mounted on the inner wall of the arc-shaped groove. Flexible steel sheets are fixedly mounted on both sides of the grinding belt 27. The side is embedded in the arc-shaped groove through a flexible steel sheet. A drive motor 29 is fixedly installed on the outer surface of the arc-shaped grinding frame 25. The output end of the drive motor 29 passes through the outer surface of the arc-shaped grinding frame 25 and is fixedly installed with the rotation center of one of the support wheels 26. Two arc-shaped support plates 28 are fixedly installed on the inner side of the arc-shaped grinding frame 25. The arc-shaped support plates 28 are in contact with the inner side of the grinding belt 27. The arc-shaped support plates 28 can provide a certain supporting force to the grinding belt 27, so that the grinding belt 27 can better grind the surface of the thrust bearing ring.

[0037] During use, the support wheel 26 is driven to rotate by the driving motor 29, so that the support wheel 26 can drive the grinding belt 27 sleeved on its outer surface to move, so that the grinding belt 27 can grind the surface of the thrust bearing ring; the arc-shaped grinding frame 25 is driven to move as a whole by the telescopic end of the electric telescopic rod 24, and the distance between the grinding belt 27 and the surface of the thrust bearing ring can be adjusted to meet different grinding requirements.

[0038] In this embodiment, the connecting assembly includes a plurality of transmission bars 20 uniformly fixedly installed on the outer periphery of the positioning tube 10 in the circumferential direction, and the inner wall of the transmission gear 19 is uniformly provided with a plurality of slots 21 matching the transmission bars 20, and the transmission bars 20 are slidably installed on the inner walls of the slots 21.

[0039] When the positioning tube 10 moves, the transmission bar 20 installed on the outer periphery of the positioning tube 10 can slide in the slot 21, so as to ensure the transmission effect between the transmission gear 19 and the positioning tube 10 while keeping the position of the transmission gear 19 unchanged.

[0040] In this embodiment, a stepper motor 23 is fixedly mounted on the inner wall of the closed end of the support tube 3 , and the output end of the stepper motor 23 passes through the end of the support tube 3 and is fixedly mounted to the rotation center of the feed tray 4 .

[0041] In this embodiment, a material receiving box 30 is fixedly installed on the top of the processing table 1, and a cushioning cotton pad is fixedly installed inside the material receiving box 30.

[0042] When the ground thrust bearing ring falls into the receiving box 30, the thrust bearing ring can be buffered by the buffer cotton belt to avoid collision of the thrust bearing ring.

[0043] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the thrust bearing ring to be ground is placed in the feeding rack 7, and the thrust bearing ring will fall into the placement groove 5 at the top of the feeding tray 4. At this time, the feeding tray 4 is driven by the stepping motor 23 to drive the thrust bearing ring to rotate toward the grinding mechanism. While the feeding tray 4 rotates, the supporting rod 8 drives the movable plate 9 to move the guide column 17 installed on the movable plate 9 in the closed-loop guide groove 16 (the guide column 17 moves from the annular flat groove to the extending section groove and the grinding section groove in sequence), so that the guide The column 17 can push the positioning tube 10 toward the feed tray 4 through the movable plate 10, so that the positioning tube 10 penetrates into the thrust bearing ring. At the same time, when the positioning tube 10 moves, it will drive the L-shaped clamping block 11 to move synchronously. Since the L-shaped clamping block 11 is movably installed with the inclined guide frame 14 through the movable column 15, when the positioning tube 10 moves toward the feed tray 4, the L-shaped clamping block 11 will extend outward, so that multiple L-shaped clamping blocks 11 can clamp the inner ring of the thrust bearing ring, so as to center the thrust bearing ring and prevent affecting the grinding accuracy during the subsequent thrust bearing ring grinding operation;

[0044] After the positioning of the thrust bearing ring is completed, as the feed plate 4 continues to rotate, the transmission gear 19 installed on the outer periphery of the positioning tube 10 will mesh with the teeth of the incomplete gear ring 22, so that the transmission gear 19 can drive the positioning tube 10 to rotate through the transmission bar 20, so that the L-shaped clamping block 11 installed on the positioning tube 10 drives the thrust bearing ring to rotate, so that the grinding belt 27 can grind the outer ring of the thrust bearing ring as a whole;

[0045] After the grinding of the thrust bearing ring is completed, the feeding plate 4 will drive the ground thrust bearing ring to rotate to the bottom position. At this time, the guide column 17 moves from the grinding segment groove to the retracted segment groove and the annular flat groove, so that the movable plate 9 drives the positioning tube 10 and the L-shaped clamping block 11 to reset, so that the positioning tube 10 is pulled out of the thrust bearing ring as a whole, so that the thrust bearing ring can fall into the receiving box 30 under its own weight, and the unloading operation is automatically completed;

[0046] By placing the thrust bearing ring into the feeding rack 7, the thrust bearing ring can be automatically positioned, clamped and rotated for grinding during the rotation of the feeding plate 4, and automatically unloaded after the grinding is completed, thereby realizing continuous grinding operations. Compared with the one-by-one processing method in the prior art, the grinding efficiency of the thrust bearing ring can be effectively improved.

[0047] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
