Clamping device for thin-wall sleeve

Abstract

The invention relates to a clamping device for a thin-wall sleeve. The clamping device comprises a fixed rod, a round plate, a connecting rod, a clamping mechanism and a driving mechanism. The clamping mechanism comprises a clamping assembly and a limiting assembly. The driving mechanism comprises a first fixed pulley and a driving assembly. According to the clamping device for the thin-wall sleeve, the thin-wall sleeve is fixed through the clamping mechanism, elastic clamping of clamping plates on the outer ring of the thin-wall sleeve is achieved through the restoring force of a first spring, and the situation that due to the fact that the clamping force is too large, the thin-wall sleeve deforms is avoided; meanwhile, the friction force of the clamping device and the thin-wall sleeve isincreased through a rubber pad and protrusions, and the thin-wall sleeve is prevented from rotating accordingly during end face machining; the end face in the thin-wall sleeve is fixed through a magnet, and therefore dual fixing on the thin-wall sleeve is achieved; and meanwhile, the magnitude of the magnetic force of the magnet is adjusted through an adjusting unit, the situation that due to thefact that the magnetic force is too large, the thin-wall sleeve deforms is avoided, the clamping assembly is controlled through the driving mechanism, and therefore the thin-wall sleeve is mounted more conveniently, and the mounting efficiency is improved.

Description

technical field [0001] The invention relates in particular to a clamping device for thin-walled sleeves. Background technique [0002] Thin-walled parts are metal parts with a wall thickness of less than 1mm. Thin-walled parts have been widely used in various industrial sectors because of their light weight, material saving, and compact structure. [0003] However, the processing of thin-walled parts is a difficult problem in turning. The reason is that thin-walled parts have poor rigidity and weak strength. [0004] The existing end face processing for thin-walled sleeves is more difficult for ordinary cars, mainly because it is difficult to control the clamping force of the thin-walled sleeves, which makes the thin-walled sleeves deform under force, resulting in machining The product that comes out is not ideal. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a clamping device for a thin-walled sleeve in orde...

Problems solved by technology

[0003] However, the processing of thin-walled parts is a difficult problem in turning. The reason is that thin-walled parts have poor rigidity and weak strength, and are easily deformed during processing, which increases the shape and position error of the parts and makes it difficult to guarantee the processing quality of the parts.

[0004] The existing end face processing for thin-walled sleeves is more difficult for ordinary cars, mainly because it is difficult to control the clamping force of the thin-walled sleeves, which makes the thin-walled sleeves deform under force, resulting in machining The product that comes out is not ideal
