Quick polishing device for planks for machining

Abstract

The invention discloses a quick polishing device for planks for machining. The quick polishing device comprises a frame and two polishing components, wherein a driven roller and a driving roller are respectively mounted at the two ends of the frame; a support roller is arranged on the middle part of the frame; each polishing component comprises a portal gantry fixed on the frame; a screw rod is inthreaded connection with the portal gantry; the bottom end of the screw rod is moveably connected with the interior of a fixing sleeve; the bottom of the fixing sleeve is fixed on a bracket through abolt; a polishing roller is arranged on the bracket through a rotating shaft. According to the invention, the two sets of polishing components are used for respectively polishing the two surfaces ofthe plank at the same time, so that the polishing efficiency is greatly increased and the polishing time is reduced; a spring is utilized to drive the polishing roller to automatically adjust the acting force on the plank surface, the control on the polishing pressure of the polishing roller is benefited and the polishing quality is guaranteed; the polishing wire on the polishing roller is conveniently replaced and the use cost of the whole polishing roller is lowered.

Description

technical field [0001] The invention belongs to the technical field of grinding devices, and in particular relates to a fast grinding device for a plate used in mechanical processing. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. The production process of a machine refers to the entire process of making a product from raw materials (or semi-finished products). For machine production, it includes transportation and storage of raw materials, production preparation, blank manufacturing, processing and heat treatment of parts, product assembly, debugging, painting and packaging, etc. The machinery required for processing consists of digital display milling machine, digital display forming grinder, digital display lathe, EDM machine, universal grinding machine, machin...

AI Technical Summary

Problems solved by technology

Existing grinding equipment usually can only polish one side of the board. After one side is polished, it is turned over and the other side of the board is polished again. The slow grinding efficiency increases the operation time and increases the workload of the workers.

In addition, during the process of grinding the surface of the plate, the grinding roller usually adopts a fixed structure, which does not change after the height of the grinding roller is adjusted, which is not conducive to the close fit between the grinding roller and the surface of the plate, resulting in uneven grinding and difficult to ensure Polishing quality
