Y-shaft double-servo power knife rest

Abstract

The invention relates to a Y-shaft double-servo power knife rest which is formed by additionally installing a power driving module and a Y-shaft module on a servo knife rest body. The power driving module is formed by using a driving motor to drive a motor end gear to rotate, the motor end gear is engaged with a clutch end driving gear after being driven by a plurality of driving gears, thereby the power driving module is connected with a clutch, a piston rod inside the clutch is connected with a piston mandrel, the piston mandrel is connected with a power output shaft, an external spline arranged on the power output shaft is matched with the clutch end driving gear, an internal spline of the power output shaft is matched with an external spline of a power knife file, a proximity switch is arranged outside a piston cavity, and the Y-shaft module comprises a Y-shaft motor, a Y-shaft upright post and a Y-shaft sliding board. Due to the adoption of the structure, the invention realizes modularization, increases the flexible selection of machine tool functions, expands the machining capacity of a machine tool, improves the whole performance of the machine tool, has simple structure and is convenient to debug, and a driving chain has low cost, high precision and high reliability.

Description

technical field [0001] The invention relates to a Y-axis double-servo powered tool holder for a turning center. Background technique [0002] With the rapid development of the national economy, the demand for turning centers and turning-milling compound machining centers in important industrial sectors such as aviation, aerospace, military industry, and power generation equipment is growing rapidly. The driven tool post is one of the core functional components of the turning center and the turning-milling compound machining center, which directly affects the performance and reliability of the machine tool. At present, the relatively mature ones in China are non-powered tool holders such as electric tool holders and hydraulic tool holders that are mainly used in economical and popular CNC lathes. However, power tool holders, including dual-servo powered tool holders and single-servo powered tool holders, are still in their infancy in my country, with low performance and reli...

Problems solved by technology

This technology has the advantage of occupying less axial space, but the crown needs high-cost machining equipment to prepare, and it is difficult to assemble and it is not easy to realize modularization

[0005] In Korean Patent No. 10-2008-0081420, the Y-axis module uses a linear rolling guide rail, but the linear rolling guide rail has poor stiffness and generally can only bear a moderate overturning load. During heavy cutting, the deformation of the guide rail will affect the stiffness of the overall tool holder and the Machining accuracy of machine tools
