Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically a continuous bearing end face grinding device. Background Technology

[0002] Bearings, as crucial basic components in modern equipment manufacturing, directly determine the overall level of various mechanical equipment through their performance, quality, and reliability. Their core function is to support rotating mechanical bodies, effectively reduce the coefficient of friction during movement, and ensure high-precision rotational motion of the mounted components. For highly precision equipment such as air conditioning compressors, the smooth, low-noise, and long-term operation of bearings is even more critical, serving as a key guarantee for their core performance. Therefore, the machining quality of bearings, especially the quality of the end faces involved in mating and sealing, has a direct impact on improving the quality of the final product and the user experience.

[0003] During the manufacturing process of bearings, burrs often remain on their end faces. To improve bearing precision and prevent these burrs from wearing down other precision components after assembly, the bearing end faces must be ground. Existing technologies often employ a device consisting of a worktable, clamping components, and a grinding head: during operation, the bearing is first fixed to the worktable using the clamping components, then the motor is started to drive the grinding head to rotate and grind one end face of the bearing. However, this approach has significant drawbacks: First, both end faces of the bearing usually need to be processed. After one end is ground, manual flipping and secondary positioning are required, a process that is not only inefficient but also poses a safety hazard as the sharp burrs can easily cut the operator's hands. Second, repeated clamping and flipping may cause accidental impacts to the bearing raceway or groove, affecting its material life and final precision. Furthermore, this method involves single-piece sequential processing; after each workpiece is completed, the machine must be stopped for unloading and loading, making assembly line operation impossible and severely restricting production efficiency and automation levels.

[0004] Based on this, a continuous bearing end face grinding device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-8As shown, a continuous bearing end face grinding device includes a grinding component 11 and a clamping component. Two grinding components 11 are symmetrically arranged inside a processing box 14. Both grinding components 11 are fixedly mounted on the bottom of a connecting plate. Chain belts 15 are symmetrically arranged inside the processing box 14 below the grinding components 11. Several clamping components are arranged at equal intervals between the two chain belts 15. Each clamping component includes a support platform 17. Each support platform 17 is fixedly connected to the chain belt 15 by a fixing rod. Each support platform 17 has a clamping mechanism at its upper end for clamping the bearing body 39. A feeding mechanism is provided inside the processing box 14 at a position corresponding to one end of the chain belt 15 to facilitate the feeding of the bearing body 39. The clamping mechanism facilitates the clamping and fixing of the bearing body 39, and the feeding mechanism facilitates the collection of the ground bearing body 39.

[0029] The connecting plate is fixedly mounted on the output end of the first electric cylinder 12, which is fixedly mounted inside the mounting tube. A guide slide rod is provided at the upper end of the processing box 14 corresponding to the position of the mounting tube. Fixed plates are fixedly mounted at both ends of the mounting tube, and a first guide slide rod is slidably mounted in the middle of each fixed plate. The first guide slide rods are all fixedly mounted on the upper end of the processing box 14. The mounting tube is fixedly mounted on the output end of the second electric cylinder 13, which is fixedly mounted on the upper end of the processing box 14. A first drive roller and a first transmission roller are fixedly mounted at both ends of the chain belt 15. A transmission shaft is fixedly mounted between the two first drive rollers and the first transmission rollers. The other rotating shafts of the first drive rollers and the first transmission rollers are rotatably mounted in a rotating hole inside the processing box 14. One rotating shaft of one first drive roller is fixedly connected to the output end of a first motor 16, which is fixedly mounted on one side of the processing box 14. The grinding component 11 and the first electric cylinder 1... 2. Both the second electric cylinder 13 and the first electric motor 16 are electrically connected to the control component 36, which is fixedly mounted on one side of the processing box 14. In use, when it is necessary to grind the bearing end, the output end of the first electric motor 16 drives the first drive roller to rotate. The first drive roller and the first transmission roller cooperate to drive the two chain belts 15 to rotate intermittently. The chain belts 15 drive several bearing platforms 17 to move intermittently. When the bearing platform 17 moves to below the grinding component 11, the output end of the first electric cylinder 12 drives the two grinding components 11 to move and start the grinding component 11, so that the grinding component 11 is in close contact with the bearing to be ground. At the same time, the output end of the second electric cylinder 13 drives the first electric cylinder 12 to move back and forth, thereby grinding the bearing end. It is worth noting that the grinding component 11 and the chain belt 15 in this application are both existing components. The specific structure and model are selected according to actual use, and the internal connection and working principle are well known, so they will not be described in detail here.

[0030] The clamping mechanism includes clamping rods 18. Clamping rods 18 are symmetrically arranged above the support platform 17. A first push rod 19 is fixedly arranged on one side of each clamping rod 18. A rotating tube 21 is slidably arranged on each first push rod 19. A rotating plate 22 is rotatably arranged on each rotating tube 21. A torsion spring is provided at the connection between the rotating tube 21 and the rotating plate 22. The rotating plate 22 is fixedly arranged on the upper end of the support platform 17. A second guide slide rod is symmetrically arranged on one side of each clamping rod 18. The second guide slide rod is fixedly arranged in a sliding hole on one side of the rotating tube 21. A first return spring 23 is provided between one end of the rotating tube 21 and one end of the first push rod 19. A first return spring 23 is provided inside the processing box 14 at a position corresponding to the position of the first push rod 19 at the upper end of the chain belt 15. A first guide plate 20 is provided, with one end of the first guide plate 20 being inclined. The first guide plate 20 is tightly attached to one end of the first top rod 19. The inner side of each clamping rod 18 is provided with an anti-slip layer. In use, when the chain belt 15 drives the support platform 17 to rotate to the upper end of the chain belt 15, the external feeding component adds the bearing body 39. Subsequently, as the chain belt 15 drives the support platform 17 to move again, one end of the first top rod 19 is tightly attached to the inclined end of the first guide plate 20, so that the first guide plate 20 guides the first top rod 19. The first top rod 19 drives the clamping rod 18 to move. When one end of the first top rod 19 is tightly attached to the flat section of the first guide plate 20, the clamping rod 18 is tightly attached to the outer side of the bearing, so that the two clamping rods 18 fix and clamp the bearing.

[0031] Each of the support platforms 17 has a positioning groove at its upper end, and each positioning groove has a lifting plate 24. A second push rod 25 is fixedly mounted at the bottom end of each lifting plate 24. The second push rod 25 has an installation groove inside, and a fixing frame 27 is slidably mounted within the installation groove. The fixing frame 27 is fixedly mounted in a fixing hole at the upper end of the support platform 17. A second return spring 26 is provided between the bottom end of the fixing frame 27 and the bottom end of the installation groove. A second guide plate 28 is fixedly mounted inside the processing box 14 at a position corresponding to the end of the chain belt 15. Both ends of the second guide plate 28 are inclined. The second guide plate 28 is positioned on the second... At one end of the push rod 25, during use, when the chain belt 15 drives the support platform 17 to rotate to the upper end of the chain belt 15 and stops, the end of the second push rod 25 is in close contact with the upper end of the second guide plate 28, so that the second guide plate 28 guides the second push rod 25. The second push rod 25 pushes the lifting plate 24 to move, and the external feeding component places the bearing body 39 on the upper end of the lifting plate 24. Then, when the chain belt 15 rotates again, the clamping rod 18 can clamp and fix the bearing body 39. Then, before the bearing body 39 moves to below the grinding component 11, the second push rod 25 separates from the second guide plate 28, so that the lifting plate 24 returns to the initial position.

[0032] Each of the rotating tubes 21 has a fixed limiting wheel 29 at one end, and the limiting wheel 29 has symmetrical limiting notches. A first limiting rod 30 is symmetrically provided inside the processing box 14 at a position corresponding to the upper limiting wheel 29 of the chain belt 15. A second limiting rod 31 is fitted to the end of each of the first limiting rods 30. Both the first and second limiting rods 30 are fixed inside the processing box 14. A rack 33 is fixed between the first and second limiting rods 30 and 31. A fixed gear ring 32 is fixed at the other end of each rotating tube 21. The fixed gear ring 32 is positioned corresponding to the rack 33. One end of each of the first limiting rods 30 is inclined. In use, when the chain belt 15 moves the bearing body 39 to the lower part of the grinding component 11... Before the first limiting rod 30 is in close contact with the upper limit notch of the limiting wheel 29, thus restricting the clamping rod 18 from rotating. After the end of the bearing body 39 is polished by a polishing component 11, the chain 15 drives the bearing platform 17 to move again. Before the bearing body 39 moves to below another polishing component 11, the limiting wheel 29 separates from the first limiting rod 30. At the same time, the fixed gear ring 32 meshes with the rack 33. During the process of the chain 15 driving the bearing platform 17 to move, the fixed gear ring 32 drives the rotating tube 21 to rotate. When the rack 33 separates from the fixed gear ring 32, the clamping rod 18 drives the bearing body 39 to rotate 180 degrees. At the same time, the limiting wheel 29 is in close contact with the first limiting rod 30 again, so that the other polishing component 11 can polish the other end of the bearing body 39.

[0033] The feeding mechanism includes a conveyor belt 34. The conveyor belt 34 is located inside the processing box 14 at a position corresponding to the other end of the chain belt 15. The two ends of the conveyor belt 34 are equipped with a second drive roller and a second transmission roller. The second drive roller and the second transmission roller are rotatably mounted inside the retainer. The retainer is fixedly mounted at one end of the processing box 14. The rotating shaft at one end of the second drive roller is fixedly connected to the output end of the second motor 35. The second motor 35 is fixedly mounted on the retainer. The width of the conveyor belt 34 is less than the distance between the two clamping rods 18. In use, when the bearing body 39 moves to the end of the first guide plate 20, the two clamping rods 18 release their clamping and fixing of the bearing body 39 under the action of the first return spring 23, causing the bearing body 39 to fall onto the upper end of the conveyor belt 34. Subsequently, the second motor 35 drives the conveyor belt 34 to rotate, and the conveyor belt 34 can transport the bearing body 39.

[0034] The bearing platform 17 is symmetrically provided with fixed rods at both ends, and each fixed rod is provided with a roller 37 at one end. The processing box 14 is provided with support plates 38 at the upper and lower ends of the chain belt 15. The support plates 38 are in close contact with the rollers 37. In use, this facilitates the support of the bearing platform 17 and prevents the processing box 14 from undergoing large deformation during grinding.

[0035] The support platform 17 is symmetrically provided with auxiliary support rods at both ends, which facilitates the auxiliary support of the support platform 17 during use.

[0036] The above embodiment discloses a continuous bearing end face grinding device. When grinding the bearing end, the chain 15 drives the support platform 17 to rotate to the upper end of the chain 15 and stops. The end of the second push rod 25 is in close contact with the upper end of the second guide plate 28, so that the second guide plate 28 guides the second push rod 25. The second push rod 25 pushes the lifting plate 24 to move. The external feeding component places the bearing body 39 on the upper end of the lifting plate 24. Subsequently, when the chain 15 rotates again, the clamping rod 18 can clamp and fix the bearing body 39. Then, before the bearing body 39 moves below the grinding component 11, the second push rod 25 separates from the second guide plate 28, causing the lifting plate 24 to return to its initial position. Before the support platform 17 drives the bearing body 39 to move below the grinding component 11, the first limiting rod 30 is in close contact with the upper limit notch of the limiting wheel 29, thereby restricting the rotation of the clamping rod 18. Then, the first electric cylinder... The output end of the first electric cylinder 12 drives the two grinding components 11 to move and start the grinding components 11, so that the grinding components 11 are in close contact with the bearing to be ground. At the same time, the output end of the second electric cylinder 13 drives the first electric cylinder 12 to reciprocate, thereby grinding the end of the bearing. After the end of the bearing body 39 is ground by one grinding component 11, the chain 15 drives the support platform 17 to move again. Before the bearing body 39 moves to below the other grinding component 11, the limiting wheel 29 separates from the first limiting rod 30. At the same time, the fixed gear ring 32 meshes with the rack 33. During the process of the chain 15 driving the support platform 17 to move, the fixed gear ring 32 drives the rotating tube 21 to rotate. When the rack 33 separates from the fixed gear ring 32, the clamping rod 18 drives the bearing body 39 to rotate 180 degrees. At the same time, the limiting wheel 29 is in close contact with the first limiting rod 30 again, so that the other grinding component 11 can grind the other end of the bearing body 39.

[0037] When the bearing body 39 moves to the end of the first guide plate 20, the two clamping rods 18 release their clamping and fixing of the bearing body 39 under the action of the first return spring 23, causing the bearing body 39 to fall onto the upper end of the conveyor belt 34. Then the second motor 35 drives the conveyor belt 34 to rotate, and the conveyor belt 34 can transport the bearing body 39.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
