一种管式快夹激光卡盘

Abstract

本申请涉及机床加工的技术领域，一种管式快夹激光卡盘包括外壳、内筒、夹筒、活塞、第二推力球轴承、推动座、压环和防尘盖，内筒同轴转动连接于外壳内侧，夹筒连接于内筒内侧，推动座同轴滑动连接于内筒外侧，活塞滑动连接于外壳内侧，推动座的另一端设有第七安装槽，压板连接于活塞的一端，压板嵌于第七安装槽内，防尘盖连接于外壳的一端，防尘盖内壁与第七安装槽槽壁相贴合。活塞通过第二推力球轴承和压环带动推动座滑动，实现夹筒夹紧或松开工件，防尘盖连接于外壳，防尘盖内壁与第七安装槽槽壁相贴合，使得压环与推动座位于外壳和防尘盖内侧，阻碍外界杂质直接进入压环与推动座的连接处，降低压环与推动座的磨损效率，提高卡盘的使用寿命。
