Problems solved by technology

Because of its light weight and easy construction, it is widely used in large factories, venues, super high-rises and other fields. It is often used in the field of steel structure processing and production. The overall structure of commonly used clamping equipment is complex. When clamping When the clamping force is applied, the clamping effect is not good. When the clamping force stops, the piston part cannot be retracted in time under the action of the spring, which not only affects the rotation of the spindle, but also makes the clamping mechanism inflexible, which is not conducive to the production process.

Abstract

A clamping device comprises a shell, a spindle and a piston part, the shell is positioned at the upper end of the spindle, the piston part is arranged in the shell, a ball and a bearing component are arranged in the shell, a conical outer surface is arranged on the bearing component, and the piston part is positioned at the lower end of the bearing component and fixedly connected with the bearing component. The clamping device is simple in whole structure, clamping effects are good when clamping force FA is applied, the piston part can retract under the action of a spring when the clamping force FA stops, rotation of the spindle are not affected, and a clamping mechanism is more flexible in work.

Description

technical field [0001] The invention relates to the field of steel structure processing and production, in particular to a clamping device. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, venues, super high-rises and other fields. It is often used in the field of steel structure processing and production. The overall structure of commonly used clamping equipment is complex. When clamping When the clamping force is applied, the clamping effect is not good. When the clamping force stops, the piston part cannot be retracted in time under the action of the spring, which not only affects ...
