Abstract

The invention discloses a twin-screw and double-polishing-channel polishing device for artificial joint balls. Two completely identical and symmetrically arranged polishing bodies are provided with a ring-shaped polishing channel. The left screw and the right screw are arranged in parallel and pass through the The polishing channel of the two polishing bodies, the driving device drives the left screw and the right screw to rotate in reverse, each polishing body has a material injection port connected to the polishing channel, the material injection port is provided with a sealer, and the polishing channel is equipped with a Magneto-rheological polishing fluid, each polishing body is provided with a magnetic field generator. The advantages of the present invention are: through the driving of the left screw and the right screw, the polishing operation can be carried out in the two polishing channels at the same time, which greatly improves the polishing efficiency. Finally, the magnetorheological polishing fluid changes from a liquid state to a quasi-solid state, forming countless magnetorheological brushes to uniformly polish all surfaces of the artificial joint ball, greatly improving the polishing yield.

Description

technical field [0001] The invention relates to a polishing device with twin-screw and double-polishing channels for artificial joint balls. Background technique [0002] The artificial joint ball is a kind of artificial prosthesis, which is used to replace the necrotic artificial joint. Its main body is spherical, and there are blind holes on the spherical main body. It is generally made of bioceramics. Due to its high precision requirements, it is generally polished Instruments often have the problem that the polishing accuracy cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to provide a double-screw and double-polishing channel polishing device for artificial joint balls, which can effectively solve the problem that the existing polishing equipment cannot meet the polishing precision requirements. [0004] In order to solve the above-mentioned technical problems, the present invention is achieved through the foll...
