Clamping mechanism

Abstract

A clamping mechanism comprises a bearing base, a clamping assembly and a pushing assembly. The clamping assembly comprises at least two clamping parts, a fixed part and a limiting part, wherein the fixed part is fixedly arranged on the bearing base, a containing hole is formed in the fixed part in a through mode, the containing hole contains the clamping parts, part of each clamping part is exposed outside the fixed part, and the clamping parts are sleeved with the limiting part. The pushing assembly comprises a pushing part, an adjusting base and an elastic part, one end of the pushing part abuts against the clamping parts, one end, far away from the clamping parts, of the pushing part is movably arranged in the adjusting base, and the elastic part is arranged in the adjusting base and elastically abuts against the pushing part. The clamping mechanism has the advantages of being long in service life and high in clamping efficiency.

Description

technical field [0001] The invention relates to a clamping mechanism, in particular to a clamping mechanism for clamping workpieces with through holes. Background technique [0002] In the process of industrial processing, it is often necessary to clamp the workpiece to move and transport the workpiece. At present, the handling of the workpiece generally utilizes the cooperation of the mechanical arm and the clamping mechanism installed at the end of the mechanical arm to clamp and transport the workpiece. In order to prevent scratching the surface of the workpiece, the clamping mechanism clamps the workpiece through the hole on the workpiece. The existing clamping mechanism includes a driving part, a plurality of clamping parts and a pusher against the multiple clamping parts. When in use, multiple clamping parts are inserted into the holes of the workpiece, driven by the driving part, the pusher pushes the multiple clamping parts to spread outwards and resist against the...

Problems solved by technology

However, in the process of repeated use, when the thrust of the pusher is uneven, multiple clamping pieces are prone to excessive deformation due to sudden changes in tension, resulting in damage to the clamping pieces, requiring frequent replacement of the clamping pieces, which affects the performance of the clamping mechanism. service life

In addition, due to the tolerance of the hole diameter, when using the same driving part, the driving force of the pushing part is limited, so that multiple clamping parts cannot be tightly opposed to the inner wall of the workpiece, resulting in multiple clamping parts not being able to clamp the workpiece tightly. thus affecting the clamping efficiency
