Expansion sleeve type clamping mechanism

The utility model is suitable for the field of workpiece clamping, and provides an expansion sleeve type clamping mechanism which comprises a mounting seat connected with equipment and a clamping base body which is arranged on the mounting seat, is of a hollow structure and is divided into at least two halves through a slicing groove. And the clamping bases are arranged at the top ends of the clamping base bodies, are of hollow inverted trapezoidal structures, are divided into half of the clamping base bodies by the slicing grooves and are used for clamping workpieces. The technical problems that in the prior art, a clamp is too fast in abrasion, short in service life and poor in clamping stability are solved. 本实用新型适用于工件夹持领域，提供了一种涨套式夹紧机构，所述涨套式夹紧机构包括连接设备的安装座，设置在所述安装座上呈中空结构且通过切片槽分割成至少两半的夹持基体，及设置在所述夹持基体顶端呈中空倒梯形结构且被所述切片槽分割成与所述夹持基体半数相同用于夹持工件的夹持基座。旨在解决现有技术中的夹具磨损过快，使用寿命低，夹紧稳定性不好的技术问题。
