Problems solved by technology

With this design, the tailstock of the machine tool can only slide manually on the hard rail, and it is difficult to accurately grasp the locking position. In addition, when processing materials with heavy weight, the tailstock of the machine tool is prone to axial movement, and the locking effect is not good

Abstract

A dual-locking mechanism of a machine tool tailstock comprises a machine tool body. A linear guide rail is arranged on the machine tool body and provided with the machine tool tailstock. The dual-locking mechanism of the machine tool tailstock is characterized in that a hydraulic locking device is arranged in the machine tool tailstock, and the machine tool tailstock is connected with a band-type brake servo motor through a screw extension rod, a screw nut, a ball screw and an elastic connecting mechanism. The dual-locking mechanism of the machine tool tailstock is simple in structure, convenient to use and good in locking effect.

Description

technical field [0001] The invention relates to machine tool equipment, in particular to a double locking mechanism for a machine tool tailstock. Background technique [0002] At present, the locking of the tailstock of the machine tool on the market is mostly carried out by hydraulic oil cylinder or servo motor brake mechanism alone. When the hydraulic cylinder is used to lock the tailstock, its locking position is fixed, and the position cannot be changed flexibly. The movement of the tailstock of the machine tool on the linear guide rail can only be done manually, and the hydraulic locking device can only make the tailstock of the machine tool Fixed in the radial direction (perpendicular to the linear guide rail), it is still possible to move upward along the linear guide rail axis, and the locking effect is not good. When processing relatively thick and heavy materials, the single locking method often cannot meet the rigidity requirements of the overall structure during...
