Abstract

A quick-replacement fixture comprises a fixture body, a fixture rod, steel balls and a locking sleeve. An installation hole is formed in one end of the fixture body, and two ball sockets are symmetrically arranged on the outer wall of the installation hole of the fixture body. The fixture rod is arranged in the installation hole of the fixture body in a sleeved mode, and locking grooves are formed in the fixture rod. The fixture body is sleeved with the locking sleeve. The inner surface of the locking sleeve is a conical surface at a certain inclination angle, the steel balls are installed in the two ball sockets respectively and clamped in the locking grooves of the fixture rod, and the inner surface of the locking sleeve presses the steel balls. The quick-replacement fixture achieves quick and easy replacement of tools, effectively relieves labor intensity and improves working efficiency.

Description

technical field [0001] The invention relates to a machining fixture, in particular to a quick-change fixture used on a drilling machine. Background technique [0002] In the tool clamping method of the drilling machine, the structure in which the inner tapered hole of the main shaft of the drilling machine is matched with the outer tapered surface of the tool handle (or transition sleeve) is generally adopted. When changing the tool, it is necessary to insert the wedge iron into the dismounting hole on the main shaft of the drilling machine, and then knock the wedge iron with a hammer to remove the tool. When machining a part with various specifications of holes, frequent tool replacement will accompany the entire machining process, and the method of using a hammer to strike a wedge iron to change tools is time-consuming, laborious and noisy. Contents of the invention [0003] The invention solves the problem of inconvenient tool replacement on a drilling machine, and pro...
