Description

Technical Field

[0001] The utility model relates to the technical field of spiral rotor processing, in particular to a polishing device for spiral rotor processing. Background Technique

[0002] A spiral rotor is a screw rod that has been machined and surface-treated with high hardness. Its upper end is a free end, and its lower end is connected to a universal shaft. A pair of mutually meshing spiral male and female rotors are installed in the cylinder of a screw compressor. Both rotors have several concave teeth, and they rotate in opposite directions. The gap between the rotors and between the casing and the rotors is only 5-10 silk. During the daily processing of spiral rotors, a polishing device is needed to assist in the polishing operation of the spiral rotors.

[0003] For example, the patent application No. 202322273747.1 discloses a polishing device for spiral rotor processing, including a cross plate.

A fixing component is installed in the inner cavity of the circular shell. The right side of the top of the cross plate is connected to a mounting frame through bolts. This utility model cooperates through a first motor, a first gear, a rotating rod, a second gear, and a circular shell, and has the advantage of a rotatable polishing function, polishing the surface of the object more evenly, achieving the best polishing effect, and improving the quality of polishing; it cooperates through a blower, a storage box, a mesh plate, a dust suction pipe, and a dust suction hood, and has the advantage of being able to suck the dust generated during polishing, so that the dust will not flow in the air, protecting the staff and making the staff healthier.

[0004] However, when this polishing device for spiral rotor processing is in use, although it can perform dust suction on the debris generated during the polishing of the spiral rotor, the cleaning effect on the debris that falls on the surface of the processing table is not high.
