Linkage self-locking device for machine tool

Abstract

The invention provides a linkage self-locking device for a machine tool. The linkage self-locking device for the machine tool is characterized in that the linkage self-locking device for the machine tool comprises a lock pin, a lock body and a linkage locking mechanism, the lock body is a main body of the device, the linkage locking mechanism is installed in the lock body, the lock pin can be inserted into a conical through hole in the center of the lock body to realize positioning and drive the linkage locking mechanism to operate and then be locked by the linkage locking mechanism. Accordingto the technical scheme, the movement characteristics and self-locking characteristics of the linkage locking mechanism are utilized to realize automatic positioning and fast and stable locking without relying on electrical control, and the applicability is higher; and the lock pin can be connected with various tools and fixtures, and the versatility is better.

Description

technical field [0001] The invention relates to the technical field of machine tool automation, in particular to a linkage self-locking device for machine tools. Background technique [0002] With the rapid development of my country's machinery manufacturing technology, comprehensive machining centers with better versatility and adaptability to various processing conditions are becoming more and more popular. Because the machining center has the characteristics of multiple functions and strong applicability, it is faced with the practical problem of processing parts with various forms and different shapes. In order to meet the processing needs of various parts, it needs to be equipped with corresponding fixtures; [0003] For example, the Chinese invention patent with the patent number: 201911398555 discloses a fixed fixture for a CNC machining machine tool, which sets a guide rail on the workbench, and installs a cylinder-driven fixture on the guide rail, adjusts the positi...
