Surface polishing device for casting wheel hub

Abstract

The invention relates to the technical field of precision casting, and discloses a surface polishing device for casting a wheel hub. The surface polishing device comprises a shell, a rotating gear is movably connected inside the shell, a chain is movably connected outside the rotating gear, a push rod is fixedly connected outside the chain, and a support plate is fixedly connected outside the push rod. Under the interaction of all structures of the device, a wheel hub can be fixed in time after being placed into the device, the wheel hub is conveyed to a designated position to be subjected to surface machining, in the polishing process, the wheel hub can be cooled in time under the action between an electromagnetic valve and a spray head, so that the effects that the wheel hub can be automatically conveyed and fixed, the outer surface of the wheel hub can be polished, and the wheel hub can be cooled in the polishing process are achieved, the polishing precision of the surface of the wheel hub is guaranteed, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of precision casting, in particular to a surface grinding device for casting wheel hubs. Background technique [0002] The hub is the part of the center of the wheel. The center is installed on the shaft to support the tire. It is cylindrical in shape. Generally, bearings are installed to avoid friction. The most common hubs are steel ring hubs and aluminum alloy hubs. [0003] In the production of automobile wheels, due to their irregular shape, casting is often used to produce automobile wheels. However, the precision of the cast wheel hubs cannot meet the requirements for use, so the surface treatment of the wheel hubs is required. It is round, and the original grinding device cannot fully polish it, so it needs to be manually refined, and more high-temperature debris will be generated during the manual finishing process, so that it will be difficult for the operator to process When there is a certain po...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the present invention provides a surface grinding device for casting wheel hubs, which can automatically transport and fix the wheel hubs, can grind the outer surface of the wheel hubs, and perform grinding on the wheel hubs during the grinding process. The advantage of cooling solves the problems that the heavy wheel hub is not easy to place outside the fixing device, it is inconvenient to automatically fix the wheel hub, and the wheel will produce more high-temperature debris during the grinding process.
