[0002] The screw is a cylindrical or conical mechanical part with a spiral groove, which is mainly used to transmit force and convert motion. The appearance of the screw is cut with a spiral groove, which can play the role of connection, tightening, transmitting force and converting the direction of motion. It is widely used in mechanical processing, chemical industry, food processing and other fields. The screw can convert rotational motion into linear motion, or convert linear motion into rotational motion through the guiding effect of the spiral surface. The structural feature of the screw is that it is composed of multiple spiral lines. The distance between the spiral lines is called the pitch, the diameter of the screw is called the screw diameter, and the ratio of the pitch to the screw diameter is called the diameter-screw ratio. In addition, the screw is also commonly found in plastic molding equipment, such as plastic profile extruders and injection molding machines. As one of the core components, the screw needs to be polished. After machining, the screw has insufficient surface finish and burrs, so the shoulder R angle of the screw needs to be polished. The current screw grinding is firstly done with an ordinary sanding belt, and then the places that the sanding belt cannot reach are manually polished. The existing sanding belt can only grind most of the screw, and the chamfered position at the root cannot be polished and needs to be manually polished. Utility Model Content
