Abstract

A pneumatic fixture for the mainshaft of machine-tool is composed of a mainshaft with bearings, a central pull rod in said mainshaft and with front end connected to clamping spring and back end with clamp releasing mechanism, a steel ball sleeve on said pull rod and with radial through holes, pull rod sleeve in said steel ball sleeve and with a ring slot, steel balls in said ring slot and matched with external sleeve via said radial through holes, a piston module with bevel bearing, and a cylinder module.

Description

technical field [0001] The invention relates to an auxiliary device of a lathe, in particular to a pneumatic clamping device with a wedge mechanism added to the tail of the main shaft of the lathe. Background technique [0002] The existing pneumatic lathe clamping device is economical, convenient and reliable, and has been widely used in the machinery industry, especially in special-purpose or semi-automatic lathes. There are two types of installation: [0003] 1. The air cylinder is installed on the main shaft, and the air cylinder rotates together with the main shaft, and a distributor controlled by a reversing valve is arranged at the back, and the distributor does not rotate with the main shaft. In this installation method, the force of the cylinder is on the main shaft itself and not on the main shaft seat superior; [0004] 2. The cylinder is installed on the machine tool, and the piston rod of the cylinder and the pull rod of the clip spring are connected through a...
