Regulating and force-bearing screw of quick changing and locking device of high-precision BT knife handle

Abstract

The invention discloses a regulating and force-bearing screw of a quick changing and locking device of a high-precision BT knife handle. An outer housing (3) is matched with a conical surface of the knife handle (1) through a conical hole; the locking device is equipped with a pull rod (8); the end part of the pull rod (8) is in threaded connection with the knife handle (1); the pull rod (8) passes through the outer housing (3) and is coaxial with the outer housing (3); the extended-out end part of the pull rod (8) is equipped with a regulating and the force-bearing screw (6); the regulating and the force-bearing screw (6) is connected and mounted on the pull rod (8) through threads, and is connected with the pull rod (8); and the regulating and the force-bearing screw (6) is locked on thepull rod (8) through a regulating rod locking nut (7). With the adoption of the technical scheme, locking force for knife handle mounting is guaranteed to be constant, quick changing and quick locking of the BT knife handle are realized, operating difficulties are reduced, production efficiency is improved, working reliability of the knife handle is improved, mounting and replacing difficulty isreduced, and processing precision of a machine tool is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical cutting machine tools, and relates to the structure for installing cutters. More specifically, the present invention relates to the adjustment and force-bearing screw of a high-precision BT tool handle quick-change locking device. Background technique [0002] At present, in the prior art, the tool handle is generally locked on the main shaft of the machine tool through a lock nut, which has low production efficiency and is difficult to install and replace; and because the locking force of the nut is affected by the movement mechanism, it will Changes occur, the size of the force cannot be constant, and it is not easy to control, which sometimes affects the reliability of processing. Contents of the invention [0003] The invention provides a high-precision BT tool handle quick-change locking device adjustment and a force-bearing screw, the purpose of which is to realize the high-precision B...
