Aperture grinding and finishing device for hardware casting machining

Abstract

According to the hole diameter grinding and finishing device for hardware casting machining, a second electric push rod is vertically assembled on the right side of the top of a workbench, a supporting seat is fixedly connected to the top of the second electric push rod, a second protective shell is assembled to the top of the supporting seat through bolts, and a servo motor is fixedly connected to the bottom end in the second protective shell; an output shaft of the servo motor penetrates through the left side wall of the second protective shell, and the output end of the servo motor is fixedly connected with a clamp. According to the polishing device, the polishing block is matched with the lantern ring, burrs on the surface of a blank workpiece are removed through friction between the polishing block and the blank workpiece, the polishing effect is achieved, the workpiece can be cleaned through the quick disassembly design of the lantern ring and the polishing block and friction between bristles on the outer side face of the lantern ring and the blank workpiece, and therefore the workload of workers is effectively reduced, and the polishing efficiency is improved. And the whole device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of hardware manufacturing, in particular to an aperture grinding and trimming device for processing metal castings. Background technique [0002] Generally, metal castings refer to metal products obtained by smelting gold, silver, copper, iron, and tin materials into liquid metals, injecting them into molds by casting methods such as pouring and injection, and grinding and polishing them after cooling. The grinding of metal castings usually uses a grinding disc to grind the blank workpiece, which is usually done manually, and electric machinery is also used; [0003] For example, a pipe fitting hardware grinding device with an application number of CN201810597879.0, which uses the cooperation of a grinding device, a cooling device, a rotating motor, etc., realizes the grinding of the inner and outer surfaces of tubular hardware, and effectively improves the processing efficiency; [0004] However, when it i...

Problems solved by technology

[0004] However, when it is in use, there is still a poor fit between the grinding disc and the blank workpiece, and the vibration between the grinding disc and the fur workpiece is relatively large due to friction, which is likely to cause head-to-head contact between the grinding disc and the workpiece, which will cause damage to the grinding disc and the workpiece. damage
