Automatic polishing tool for machine barrel

Abstract

The invention discloses an automatic polishing tool for a machine barrel. The automatic polishing tool comprises a machine barrel supporting seat, a machine barrel rotating motor, a driving wheel, a driven wheel, the machine barrel, a bidirectional lead screw, a left-hand thread, a first nut, a right-hand thread, a second nut, automatic telescopic rods, polishing strips, holes, lead screw supporting seats, a coupler, a lead screw motor, a motor supporting seat and a controller. The automatic polishing tool for the machine barrel has the advantages that according to the tool, a traditional polishing wheel is split into the plurality of arc-shaped polishing strips of the same structure, and the arc-shaped polishing strips are combined and mounted to form a polishing wheel, so that later replacement and maintenance are facilitated, and the polishing strips made of different materials can be replaced according to different polishing requirements; meanwhile, the telescopic function of the automatic telescopic rods is combined, the distance between the polishing strips and the bidirectional lead screw can be adjusted according to the inner diameter of the machine barrel, and therefore, the tool can adapt to machine barrels of various types; and by utilizing the double-nut function of the bidirectional lead screw, the left and right groups of polishing strips can simultaneously move reversely for polishing, so that the working efficiency is improved, and certain economic value is achieved.

Description

technical field [0001] The invention relates to automatic polishing tooling for machine barrels, belonging to the technical field of machine barrels. Background technique [0002] As an important component in the extrusion compression molding system, the barrel works together with the screw to accommodate the screw, making it rotate in the barrel, and extruding the plastic in the barrel into injection molding. In order to ensure the continuous extrusion raw material molding production of the extruder, it is necessary to reduce the surface roughness of the inner wall of the barrel. Therefore, during the production and processing of the barrel, it is necessary to deburr the inner wall, remove the surface convex peak, and remove the stubborn attachment. The oxide layer and dirt impurities are treated in order to obtain a smooth surface. [0003] There are many methods of barrel polishing, which refers to the use of mechanical, chemical or electrochemical effects to reduce the ...
