Side polisher for rectangular workpiece

Abstract

A side polisher for a rectangular workpiece comprises a conveying device and a polishing device. The conveying device comprises a frame (1), a first conveying line (I) of a conveying belt (2), a second conveying line (II) of the conveying belt (2) and a lifting turning table (12). The first conveying line (I) is connected with the second conveying line (II) through the lifting turning table (12). The polishing device comprises a fixed frame (4), a polishing head (5), a main arm (6), an auxiliary rod (7), a rocker (10), a flange (8), a clamping head (9), and a positioning block (11). The main arm (6) is connected with the fixed frame (4) through a first revolute pair (E) and connected with one end of the auxiliary rod (7) through a ball pair (F). A screw rod part at the other end of the auxiliary rod (7) is in a screw rod thread transmission with a nut (G) fixed at one end of the rocker (10). The other end of the rocker (10) is connected with the fixed frame (4) through a second revolute pair (D). The polishing head (5) is connected to the tail end of the main arm (6) through the flange (8). The rectangular workpiece (3) is positioned by positioning blocks (11) symmetrically disposed on two sides of the conveying belt (2) and clamped by the clamping head (9). The side polisher is simple in structure, easy to control, fine in adaptability, high in automation level and fine in polishing quality.

Description

technical field [0001] The invention mainly relates to the grinding of the sides or chamfers of rectangular workpieces, and in particular provides an efficient assembly line grinding machine for the polishing and grinding of the sides or chamfers of rectangular workpieces such as notebook computer casings. Background technique [0002] Rectangular workpieces, such as: laptop casings, metal sheet metal or structural parts, castings, etc., which are molded by injection, will inevitably have burrs on the corners and corners during the manufacturing process. have a certain impact. Therefore, the grinding process is extremely necessary, and the quality of the grinding directly affects whether the subsequent process can be carried out smoothly and the final quality of the product. [0003] According to different operation methods, grinding can be divided into manual grinding and machine grinding. At present, for surfaces with irregular curved surfaces, manual grinding is general...

AI Technical Summary

Problems solved by technology

At present, for irregular curved surfaces, manual grinding is generally used, which has lower efficiency, poorer quality, and greater labor consumption than machine grinding; for relatively flat and large-area surfaces, general-purpose robots are generally used for grinding. Therefore, in In the process of mass production, in order to save production costs and improve the quality of grinding, automatic robots are often used for grinding

However, for the grinding of the side or chamfer of a rectangular workpiece, if a general-purpose robot is used for grinding, the cost is high and the grinding efficiency is low. Therefore, an efficient automatic grinding device is urgently needed
