Negative-pressure adsorptive type thin sheet polishing device

Abstract

The invention discloses a negative-pressure adsorptive type thin sheet polishing device. The negative-pressure adsorptive type thin sheet polishing device comprises a pedestal, a worktable, a negative-pressure box, a movable base and a bidirectional screw rod; the worktable is fixed to the central position of the top of the pedestal through a supporting column; the negative-pressure box is designed in a manner that the top is opened, and is fixed to the bottom of a top plate of the worktable in a clinging manner; the movable base is arranged on the worktable; and the bidirectional screw rod isrotationally installed at the central position of the bottom of the top plate by virtue of seat-provided bearings which are arranged at the left and right sides. According to the negative-pressure adsorptive type thin sheet polishing device disclosed by the invention, a thin sheet is adsorbed on the worktable in a negative-pressure manner, so a part of the thin sheet body is prevented from protruding, and thus the polishing effect is not affected; the negative-pressure adsorptive type thin sheet polishing device is simple in structure and easy to implement and can also regulate the feed rateof a polishing disc so as to meet different polishing requirements; meanwhile, transmission is realized by utilizing a screw rod so that more accurate transmission is realized; the negative-pressure adsorptive type thin sheet polishing device is convenient to control so as to guarantee the polishing precision; a guide rod is provided with scale lines so that a worker can know the feed rate of thepolishing disc more visibly.

Description

technical field [0001] The invention relates to an industrial machine, in particular to a negative pressure adsorption thin plate polishing device. Background technique [0002] The thin steel plate is cold-rolled or hot-rolled steel plate. Requirements for thin steel plates: the surface is flat and smooth, and the thickness is uniform. It is allowed to have a tight iron oxide film, and there must be no defects such as cracks and scars. The process is divided into hot-rolled steel sheet and cold-rolled steel sheet. Mainly used in Changlin Dongfan, automobiles, electrical equipment, vehicles, agricultural machinery, containers, steel furniture, etc. [0003] The thin plate needs to go through a polishing process during the processing process. Due to the small thickness of the thin plate, part of the plate body is prone to bulge during the polishing process, thereby affecting the polishing effect. At the same time, the existing thin plate polishing device also has the disadv...

Problems solved by technology

[0003] The thin plate needs to go through a polishing process during the processing process. Due to the small thickness of the thin plate, some plate bodies are prone to bulges during the polishing process, which affects the polishing effect. At the same time, the existing thin plate polishing device also has the disadvantage of inconvenient adjustment.
