Description

Technical Field

[0001] This utility model relates to the field of flange shaft processing, and in particular to a polishing device for flange shaft processing. Background Technology

[0002] A search of Chinese patents revealed publication number CN222155126U, which discloses a polishing device for processing automotive flange shafts. The device includes a processing table with a support connected to its top surface. First bearings are positioned on both sides of the support's interior. A one-way screw connects two of the first bearings, with one end extending into the support and connecting to the output of a first motor. A movable block is also connected to one end of the one-way screw. This invention utilizes a clamping mechanism and a movable polishing host to allow the operator to fix both ends of the automotive flange shaft onto the clamping mechanism. By adjusting the position of the polishing host and rotating the clamping mechanism, automatic polishing of the automotive flange shaft can be achieved. Furthermore, by adjusting the positions of the clamping blocks and upright blocks on the clamping mechanism, different sizes of automotive flange shafts can be fixed, allowing the polishing device to accommodate a wider range of sizes and thus improving its adaptability.

[0003] Existing polishing equipment is inconvenient for changing polishing discs. Generally, when polishing flange shafts, a coarse polishing disc is used first, followed by a fine polishing disc. After polishing with the coarse disc, it needs to be disassembled and replaced with a fine polishing disc. However, polishing discs are usually fixed with bolts, making the replacement process cumbersome, increasing workload, reducing work efficiency, and lacking protective functions. During the polishing of flange shafts, debris is generated. This debris is thrown out by the polishing disc and splashes onto personnel, causing injury and posing a safety hazard. Furthermore, the debris falls to the ground, polluting the working environment. To solve the above problems, we propose a polishing device for flange shaft processing. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for flange shaft processing, which has the advantages of easy replacement of polishing discs and protective function.

This achieves the purpose of facilitating the replacement of polishing discs, reducing workload and improving work efficiency.

[0023] 2. This utility model achieves its protective function by lowering the telescopic rod along the fixed rod when the lifting frame descends, which in turn lowers the protective cover, covering the polishing seat and preventing debris from flying out. This avoids personnel injury and improves safety. Attached Figure Description

The limiting plate 10 and the turntable 6 are connected to each other. A first spring 11 is provided between the inner walls of the disc 6. A fixing hole 12 is provided on the surface of the fixing block 5, and the fixing hole 12 is engaged with the locking rod 9. By moving the pull block 26, the locking rod 9 is disengaged from the fixing hole 12. Then, the turntable 6 is rotated to rotate the polishing disc 8 of the required coarseness to the bottom. Then, the locking rod 9 is released, and the locking rod 9 is engaged with the fixing hole 12 under the action of the first spring 11, thus fixing it and completing the replacement. This achieves the purpose of facilitating the replacement of the polishing disc 8, reducing the workload and improving work efficiency.

The groove 24 is opened on the inner wall of the fixed frame 2. By setting the slider 23 and the groove 24, the lifting frame 4 is offset, thereby improving stability.

[0034] refer to Figure 1 and Figure 2 The surface of the turntable 6 is provided with heat dissipation holes 25. By setting the heat dissipation holes 25, the heat dissipation efficiency is improved and the stability of the motor 7 is ensured.

[0035] refer to Figure 3 One end of the locking rod 9 is bolted with a pull block 26, which facilitates the movement of the locking rod 9.

[0036] Example 2:

[0037] refer to Figure 1 , Figure 2 and Figure 5 A fixed rod 13 is fixedly sleeved on the inner wall of the lifting frame 4. A telescopic rod 14 is slidably sleeved on the inner wall of the fixed rod 13. A second spring 15 is provided between the telescopic rod 14 and the inner wall of the fixed rod 13. A protective cover 16 is bolted to the bottom of the telescopic rod 14. A square groove 17 is opened on the top of the protective cover 16. A fixing mechanism 18 is provided on the top of the base 1. When the lifting frame 4 descends, it drives the fixed rod 13 to lower the telescopic rod 14. The descent of the telescopic rod 14 drives the protective cover 16 to descend. The protective cover 16 covers the polishing seat 19 to prevent debris from flying out. This achieves the purpose of protection, avoids personnel injury, and improves safety.

[0038] refer to Figure 1 and Figure 2 The fixing mechanism 18 includes a polishing seat 19, which is bolted to the top of the base 1.

[0040] refer to Figure 1 and Figure 2 A pad 28 is bolted to the bottom of the base 1. The stability of the device is improved by setting the pad 28.

[0041] Brief description of the usage process: Move the pull block 26, which in turn moves the locking rod 9. The locking rod 9 disengages from the fixing hole 12. Rotate the turntable 6 to rotate the polishing disc 8 of the required coarseness to the bottom of the turntable 6. Then release the locking rod 9, which engages with the fixing hole 12 under the action of the first spring 11, thus fixing it and completing the replacement. This facilitates the replacement of the polishing disc 8. When polishing the flange shaft, the hydraulic rod 3 drives the lifting frame 4 to descend, causing the polishing disc 8 and the protective cover 16 to descend. When the protective cover 16 contacts the base 1, the telescopic rod 14 retracts, and the polishing disc 8 continues to descend into the protective cover 16 until it reaches the polishing position. During polishing, the protective cover 16 blocks the debris, preventing it from flying out, thus achieving the purpose of protection.
