Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, and more specifically, to a hub grinding wheel which can be threaded and tightened. Background Art

[0002] The wheel hub is a cylindrical component whose center is mounted on the axle and whose inner profile supports the tire. After the car has been running for a period of time, the wheel hub will often rust. Therefore, the owner needs to regularly polish and rust-proof the wheel hub to ensure the safety performance of the car.

[0003] At present, the treatment plan for wheel hub grinding and rust removal by maintenance personnel is mainly to spray detergent on the wheel hub and then use cleaning tools such as wire brushes to manually remove rust. This process is laborious and time-consuming, and often cannot completely remove the rust on the wheel hub.

[0004] After searching, a Chinese patent with publication number CN204353932U discloses a wheel hub grinder. The structure drives the rust removal device through a handheld drilling machine, and uses a grinding wheel to quickly remove rust on the surface of the wheel hub. At the same time, the grinding wheel is preferably a mesh fiber structure formed by nylon non-woven yarn. The grinding wheel of this structure can effectively remove rust on the wheel hub. A frosted layer or steel wire for facilitating rust removal can also be provided on the surface of the grinding wheel. The structure is simple, easy to use, saves effort and time, and the rust removal is more thorough.

[0005] However, in actual use, the grinding wheel and the disc are connected by a nylon tape structure. Since the grinding wheel needs to rotate quickly during operation, when it is fixed by the nylon tape, it is easy to cause the grinding wheel to shift during the grinding process, thereby affecting the use effect and posing a safety hazard.

[0008] A wheel hub grinding wheel that can be threaded and tightened comprises a grinding wheel, a thread groove is provided on the surface of the grinding wheel, a thread column is provided inside the thread groove, a disc is provided on one side of the thread column, and a fixing mechanism is provided on one side of the disc;

[0009] The fixing mechanism includes two mounting grooves opened on the surface of the disc, a fixing block is arranged inside the two mounting grooves, two springs are arranged on one side of the fixing block, a movable clamping block is arranged on one side of the two springs, a movable groove is opened on the surface of the grinding wheel, and a pushing block is movably connected inside the movable groove.

[0010] By adopting the above technical solution: in order to facilitate the installation and disassembly of the grinding wheel, and through two-layer fixation, the stability is improved to prevent deviation during the grinding process.

[0011] As a further description of the above technical solution: a grinding cylinder is sleeved around the pushing block, a threaded rod is arranged on one side of the disc, and abrasive particles and a brush head are evenly distributed on the surface of the grinding wheel, and the brush head is arranged on one side of the abrasive particles.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By setting a fixing mechanism, compared with the prior art, the threaded column on one side of the disc is rotated into the threaded groove opened on the surface of the grinding wheel, and then the movable clamping block is squeezed downward to drive the spring to be squeezed and deformed, so that the movable clamping block enters the movable groove opened inside the grinding wheel, thereby facilitating fixation, and then one end of the threaded rod is rotated into the position of the external wheel hub, thereby improving the stability during the grinding process, and a protective layer is set on the surface of the threaded column and the mounting groove. The protective layer is made of polyurethane paint material, and its main components are polyurethane resin and pigment.
