Technical Field

[0001] This utility model relates to the field of wheelchair manufacturing and processing technology, specifically to an all-around polishing device for wheelchair manufacturing with protective functions. Background Technology

[0002] Grinding equipment for wheelchair production is a specialized piece of equipment used for surface treatment of metal parts for wheelchairs. It is mainly used for deburring, grinding welds, and surface finishing of structures such as wheelchair frames, support tubes, and connectors. It typically uses a robotic arm or a fixed grinding head structure, combined with tools such as grinding wheels, sanding belts, or polishing wheels. Through program control or manual operation, it can grind different angles and areas of the workpiece. It features easy operation and strong adaptability, and can effectively improve the surface quality and appearance consistency of wheelchair parts, while reducing the errors and labor intensity caused by manual grinding. It is an important auxiliary equipment in the wheelchair production process to ensure that the product meets safety and aesthetic requirements.

[0003] Authorization announcement number CN213351900U discloses an all-around grinding device for wheelchair production with protective functions. The technical solution is as follows: "It includes a worktable, a fixture mechanism, a fixing device, and a grinding assembly fixedly installed on the worktable. The worktable is a rectangular plate structure, and multiple support legs are fixedly installed at the bottom of the worktable. A height fine-adjustment mechanism is fixedly installed in the middle of the worktable." The beneficial effect is that it can clamp and stabilize parts located on the fixture plate according to their specific size, preventing parts from flying out and causing injury during grinding.

[0004] The above technical solution has the following drawbacks: although the protective baffle can block the splashing of waste, the protective baffle needs to be rotated and adjusted every time it is used. Not only do the four protective baffles need to be adjusted, but a structure is also needed to fix them. This is quite troublesome every time it is used. Therefore, an all-round grinding device for wheelchair production with protective function is proposed to solve the problems mentioned above. Utility Model Content

At this time, the wheelchair processing parts can be clamped and fixed by the action of the adjusting seat 9, connecting rod 10 and clamp 11. Then, push the protective cover 13 to the left to completely cover the grinding assembly. Then, tighten the fixing screw 17 to push the sealing plate 15 to move downward. At this time, the electric lifting rod 3 and the grinding motor 4 can be started to drive the grinding disc 5 to move downward and rotate. At this time, the wheelchair processing parts can be ground to prevent waste chips from flying.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
