Description

Technical Field

[0001] This utility model relates to the field of motor bearing manufacturing technology, specifically a positioning mechanism for motor bearing manufacturing. Background Technology

[0002] In the production of motor bearings, surface grinding of the bearing races is a crucial process to ensure their precision and service life, requiring a positioning mechanism to stably clamp the bearing races. Currently, existing positioning mechanisms generally adopt a single-station clamping design. After completing the grinding of the current bearing race, the machine must be stopped, the processed bearing race removed, and a new bearing race to be processed must be re-clamped before the equipment can be restarted to continue grinding, affecting the processing efficiency of the bearing races.

[0003] As in the prior art, Chinese utility model publication CN221793069U discloses a bearing processing positioning mechanism. This utility model includes a fixed base plate, and a clamping mechanism is fixedly installed on one side of the fixed base plate. The clamping mechanism includes a fixed frame. In the above structure, because the bearing ring is clamped at a single station, when the bearing ring is disassembled and re-clamped, the equipment generates a lot of ineffective working time due to frequent machine stops waiting for disassembly and reassembly operations. That is, the problem of low overall processing efficiency caused by clamping the bearing ring at a single station exists. Therefore, we need to propose a positioning mechanism for motor bearing production. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning mechanism for motor bearing production, so as to solve the problem in the above-mentioned background technology that when clamping bearing rings at a single station, the bearing rings need to be disassembled and re-clamped before the bearing rings can continue to be ground. The equipment generates a lot of invalid working hours due to frequent machine stops waiting for disassembly and assembly operations, resulting in low overall processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning mechanism for motor bearing production includes: a first rotating seat with a first clamping rod and a second clamping rod movably mounted on its side, wherein multiple sets of positioning blocks arranged in pairs are evenly mounted on the surfaces of the first and second clamping rods; a roller seat mounted on the side of the first and second clamping rods, wherein a movable roller is movably mounted inside the roller seat; a pushing mechanism and a movable plate mounted on the pushing mechanism, wherein a second rotating seat is movably mounted on the side of the movable plate, and a plug-in block for pushing the first and second clamping rods is fixedly connected to the side of the second rotating seat, wherein two sets of inclined portions are symmetrically opened on the plug-in block, and the surface of the movable roller contacts the inclined portions.

[0007] Preferably, it also includes a support, on the side of which a drive motor is fixedly mounted, and the output shaft of the drive motor is fixedly mounted on the side of the first rotating seat.

[0008] Preferably, the pushing mechanism includes a fixed block, a cylinder, a guide rail, and a slider. The fixed block and the guide rail are both fixedly installed on the top of the support. The cylinder is fixedly installed on the side of the fixed block. The telescopic rod of the cylinder is fixedly installed on the side of the moving plate. The slider is fixedly installed on the bottom of the moving plate. The moving plate is slidably installed on the guide rail.

[0009] Preferably, it also includes a fixing frame fixedly installed on the side of the first rotating seat, wherein the fixing frame is open on both sides and one end, and the plug-in block is inserted into the opening at one end of the fixing frame.

[0010] Preferably, the surface of the plug block is in contact with the inner wall of the fixing frame.

[0011] Preferably, a first mounting plate is fixedly installed on the inner wall of the fixing frame, and a pull spring for dragging the first clamping rod and the second clamping rod to reset is hung on both sides of the first mounting plate, and the other end of the pull spring is hung on the side of the first clamping rod and the second clamping rod.

[0012] Preferably, a second mounting plate is fixedly installed on the inner wall of the fixing frame, and both sides of the second mounting plate are fixedly connected with stop bars for blocking the first clamping rod and the second clamping rod from being dragged and reset by the pulling spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the design of a first clamping rod, a second clamping rod, a movable roller, and a plug-in block, allows the bearing rings that need to be clamped and positioned to be fitted onto the first and second clamping rods. When the moving plate is driven by the pushing mechanism to move the second rotating seat, the plug-in block can push the first and second clamping rods through the movable roller, allowing the first and second clamping rods to open and clamp and fix the bearing rings. This enables the simultaneous clamping and fixing of multiple bearing rings, and allows for the simultaneous replacement of multiple bearing rings. This avoids the frequent machine stops required for installing and removing bearing rings in existing designs, simplifies the installation and removal process, significantly reduces ineffective working hours, and significantly improves overall processing efficiency. It can better meet the needs of large-scale production of motor bearings and reduce production costs. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] A positioning mechanism for motor bearing manufacturing, comprising:

[0022] A first rotating seat 3 has a first clamping rod 10 and a second clamping rod 11 movably mounted on its side. Multiple sets of positioning blocks 13 arranged in pairs are evenly mounted on the surfaces of the first clamping rod 10 and the second clamping rod 11. A roller seat 16 is mounted on the side of the first clamping rod 10 and the second clamping rod 11. A movable roller 17 is movably mounted inside the roller seat 16. A pushing mechanism and a moving plate 6 mounted on the pushing mechanism are also included. A second rotating seat 9 is movably mounted on the side of the moving plate 6. A plug-in block 14 for pushing the first clamping rod 10 and the second clamping rod 11 is fixedly connected to the side of the second rotating seat 9. Two sets of inclined portions 15 are symmetrically opened on the plug-in block 14. The surface of the movable roller 17 contacts the inclined portion 15.

[0023] It should be noted that when the bearing ring 22 is clamped, the positioning block 13 positions the bearing ring 22, thereby positioning the bearing ring 22 so as to clamp and fix the bearing ring 22.

[0024] When the first clamping rod 10 and the second clamping rod 11 open to clamp the bearing ring 22, the first clamping rod 10 and the second clamping rod 11 are set horizontally, and the bearing ring 22 is in a horizontal rotation state. At this time, the outer ring grinding surface of the bearing ring can maintain a stable relative position with the grinding equipment, ensuring that the grinding trajectory is uniform and reducing the processing error caused by the clamping angle deviation.

[0025] The tilt angle of the inclined part 15 has been optimized (designed according to the required opening angle of the clamping rod). When the movable roller 17 rolls along the surface of the inclined part 15, the inclined surface generates a component force perpendicular to the contact surface of the movable roller 17. This component force is transmitted to the first clamping rod 10 and the second clamping rod 11 through the roller seat 16, driving the first clamping rod 10 and the second clamping rod 11 to open outward with the first rotating seat 3 as the fulcrum. This can avoid damage to the bearing ring caused by sudden changes in clamping force.

[0026] In an optional embodiment: such as Figure 1 and Figure 2 As shown, it also includes a support 1, on the side of which a drive motor 2 is fixedly mounted, and the output shaft of the drive motor 2 is fixedly mounted on the side of the first rotating seat 3.

[0027] It should be noted that the first rotating seat 3 is driven by the drive motor 2 to rotate the first clamping rod 10 and the second clamping rod 11, so that the bearing ring 22 is slowly rotated and adjusted when the first clamping rod 10 and the second clamping rod 11 rotate, so as to facilitate the uniform grinding of the bearing ring 22.

[0028] In an optional embodiment: such as Figure 1 As shown, the pushing mechanism includes a fixed block 4, a cylinder 5, a guide rail 7, and a slider 8. The fixed block 4 and the guide rail 7 are both fixedly installed on the top of the support 1. The cylinder 5 is fixedly installed on the side of the fixed block 4. The telescopic rod of the cylinder 5 is fixedly installed on the side of the movable plate 6. The slider 8 is fixedly installed on the bottom of the movable plate 6. The movable plate 6 is slidably installed on the guide rail 7.

[0029] It should be noted that the guide rail 7 and the slider 8 work together to guide the moving plate 6, so that when the cylinder 5 pushes the moving plate 6 to move, the moving plate 6 can horizontally drive the second rotating seat 9 and the plug block 14 to move.

[0030] In an optional embodiment: such as Figure 2 and Figure 3 As shown, it also includes a fixed bracket 12 fixedly installed on the side of the first rotating seat 3. The fixed bracket 12 has openings on both sides and one end. The plug-in block 14 is inserted into the opening at one end of the fixed bracket 12, and the surface of the plug-in block 14 is in contact with the inner wall of the fixed bracket 12.

[0031] It should be noted that by inserting the plug 14 into the fixed frame 12, the fixed frame 12 can be supported and positioned, thus ensuring the stability of the first rotating seat 3 and the fixed frame 12 during rotation.

[0032] In an optional embodiment: such as Figure 2 and Figure 3 As shown, a first mounting plate 18 is fixedly installed on the inner wall of the fixing frame 12. Pulling springs 19 for dragging the first clamping rod 10 and the second clamping rod 11 to reset are hung on both sides of the first mounting plate 18. The other end of the pulling spring 19 is hung on the side of the first clamping rod 10 and the second clamping rod 11.

[0033] A second mounting plate 20 is fixedly installed on the inner wall of the fixed frame 12. Both sides of the second mounting plate 20 are fixedly connected with stop bars 21, which are used to block the first clamping rod 10 and the second clamping rod 11 from being dragged and reset by the pull spring 19.

[0034] It should be noted that, since both the pull spring 19 and the stop bar 21 are located in the opening on the side of the fixed frame 12, after the bearing ring 22 is polished and the plug block 14 is moved out of the fixed frame 12, the pull spring 19 is used to drag the first clamping rod 10 and the second clamping rod 11, so that the first clamping rod 10 and the second clamping rod 11 can be tilted, so as to facilitate the disassembly and replacement of the bearing ring 22 on the first clamping rod 10 and the second clamping rod 11;

[0035] When the spring 19 is pulled to drag the first clamping rod 10 and the second clamping rod 11, the first clamping rod 10 and the second clamping rod 11 tilt and press against the stop rod 21. The stop rod 21 blocks the first clamping rod 10 and the second clamping rod 11, preventing them from colliding.

[0036] In practical use, firstly, the bearing ring 22 is fitted onto the first clamping rod 10 and the second clamping rod 11. The position of the bearing ring 22 is positioned by the positioning block 13. After fitting the bearing ring 22 to be ground onto the first clamping rod 10 and the second clamping rod 11, the insertion block 14 is aligned with the opening at the end of the fixed frame 12. The cylinder 5 is activated, and the telescopic rod of the cylinder 5 pushes the moving plate 6, causing the moving plate 6 to move the second rotating seat 9 and the insertion block 14 closer to the fixed frame 12, so that... The plug-in block 14 is inserted into the fixed frame 12. When the plug-in block 14 is inserted into the fixed frame 12, the movable roller 17 contacts the inclined part 15. The inclined surface of the inclined part 15 pushes the movable roller 17, so that the first clamping rod 10 and the second clamping rod 11 can open. The first clamping rod 10 and the second clamping rod 11 can open and clamp and fix the bearing ring 22, so as to achieve simultaneous clamping and fixing of multiple bearing rings 22. The plug-in block 14 supports the fixed frame 12.

[0037] Start the drive motor 2. The output shaft of the drive motor 2 drives the first rotating seat 3 to rotate. When the first rotating seat 3 rotates, it drives the first clamping rod 10 and the second clamping rod 11 to rotate. When the first clamping rod 10 and the second clamping rod 11 rotate, the bearing ring 22 can be slowly rotated and adjusted, which makes it easier for the grinding equipment to grind the bearing ring 22.

[0038] After grinding the bearing ring 22, start the cylinder 5. The telescopic rod of the cylinder 5 retracts, causing the moving plate 6, the second rotating seat 9 and the plug block 14 to move away from the fixed frame 12, so that the plug block 14 moves out of the fixed frame 12. When the plug block 14 moves out of the fixed frame 12, the spring 19 is pulled to drag the first clamping rod 10 and the second clamping rod 11, so that the first clamping rod 10 and the second clamping rod 11 slowly tilt. At this time, the bearing ring 22 on the first clamping rod 10 and the second clamping rod 11 can be disassembled and replaced.

[0039] In this application, the control method of the drive motor 2 and the cylinder 5 is to automatically control them through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
