Metal exterior surface automatic polishing machine

Abstract

The invention relates to an automatic polishing machine for the outer surface of metal. The polishing machine comprises a base with a table plate, wherein a polishing support base which can slide front and back and a fixing support base which can slide left and right are arranged on the base; a polishing wheel is arranged on the polishing support base; a powerless bracket and a power bracket are arranged on the fixing support base; a piece of square steel which can sleeve a component to be processed is rotationally fixed between the powerless bracket and the power bracket; a feeding amount adjusting device is arranged on the base, and comprises a screw rod and an adjusting rod; the screw rod is arranged in the sliding direction of the polishing support base; the polishing support base is in threaded transmission connection with the screw rod directly or through a middle mechanism; the adjusting rod is fixed at the end part of the screw rod; the center of gravity of the adjusting rod is positioned on one side of the center of the screw rod. The adjusting rod is used for adjusting the feeding amount of the polishing wheel. The polishing machine is simple in structure, relatively low in cost, small in occupied space, simple to maintain, stable and reliable to adjust, and relatively small in adjusting force, and the possibility that the surface of the component to be processed is damage due to the pressing of the polishing machine is low.

Description

technical field [0001] The invention relates to a polishing device, in particular to an automatic metal outer surface polishing machine. Background technique [0002] For the polishing of the metal outer surface, the structure of the prior art polishing wheel plus reciprocating motion, for example, is named "A Round Tube Outer Surface Polishing Machine" (authorized announcement number: CN203438054U), which includes a frame, a pipe rotating motor, a pipe fixture, The polishing wheel rotating motor and the polishing wheel; the pipe rotating motor that can move horizontally and vertically is placed on the frame; the pipe fixture and the polishing wheel are respectively connected with the output shafts of the pipe rotating motor and the polishing wheel rotating motor; the round pipe is fixed on the pipe fixture Above; the polishing wheel rotating motor can move along the axial direction of the round pipe and is arranged on one side of the round pipe; wherein, there are two polis...

Problems solved by technology

In this published patent, the feed rate adjustment of the polishing wheel is connected with the corresponding hydraulic drive device through the motor base. This structure has a high cost, and although the hydraulic pressure is relatively stable, it has a large force and is easy to deform the parts to be processed.
