Abstract
The invention discloses a method for improving connection coaxiality of a ball screw and a servo motor. After ball screw is connected with an output shaft of the servo motor through a coupler, a ball screw mounting bearing and the servo motor are fixed by a ball screw mounting seat of an integral structure, so that relative positions of the ball screw mounting bearing and the servo motor are ensured to improve the connection coaxiality of the ball screw and the servo motor. The mounting seat of the integral structure can be used for simultaneously mounting the ball screw mounting bearing and the servo motor, so that the coaxiality of the ball screw and the servo motor is improved, and stability and precision of a machine tool can be improved. The method is simple and easy to implement, and a device for improving connection coaxiality of the ball screw and the servo motor is easy in manufacture, low in cost and fine in use effect.
Description
Technical field
The present invention relates to a kind of installation method and device of machine tool component, especially a kind ofly improve ball screw is connected axiality with servomotor method and device.
Background technology
At present, ball screw with realize direct the connection mainly of servomotor through shaft coupling.Although adopt yielding coupling can reduce the requirement of ball screw and servomotor output shaft axiality,, make the servomotor job insecurity because the axiality missionary society of ball screw and servomotor output shaft causes machine tool accuracy to reduce.
Summary of the invention
The objective of the invention is: a kind of ball screw is connected axiality with servomotor method and device that improve is provided, and it can effectively improve the axiality that ball screw is connected with servomotor, to overcome the deficiency of prior art.
The present invention is achieved in that and improves ball screw is connected axiality with servomotor method; With ball screw with after the output shaft of servomotor is connected through shaft coupling; Adopt the ball screw mount pad of monolithic construction to fix ball screw installation bearing and servomotor; Thereby guarantee the relative position between them, be connected axiality with servomotor to improve ball screw.
Improve ball screw is connected axiality with servomotor device; Comprise ball screw, servomotor, ball screw installation bearing; Ball screw is connected through shaft coupling with servomotor; Ball screw is installed bearing and is installed on the ball screw, between servomotor and ball screw installation bearing, is connected with all-in-one-piece ball screw mount pad.
Be provided with bearing pre-tightened adjustment lid in the bearings mounted outer end of ball screw.
Owing to adopted technique scheme; Compared with prior art, the present invention adopts the mount pad of monolithic construction, and it can be installed ball screw simultaneously bearing and servomotor are installed; With the axiality of raising ball screw and servomotor, thereby improve the stability of lathe and the precision of lathe.Method of the present invention is simple, implements easily, and the device that is adopted is made easily, and is with low cost, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
The specific embodiment
Embodiments of the invention: improve ball screw is connected axiality with servomotor method; With ball screw with after the output shaft of servomotor is connected through shaft coupling; Adopt the ball screw mount pad of monolithic construction to fix ball screw installation bearing and servomotor; Thereby guarantee the relative position between them, be connected axiality with servomotor to improve ball screw.
Improving ball screw, be connected the structure of device of axiality with servomotor as shown in Figure 1; Make the ball screw 1 and the servomotor 2 of a routine; Ball screw is installed bearing 3 be installed on the ball screw 1, ball screw 1 is connected through shaft coupling 4 with servomotor 2; Produce the ball screw mount pad 5 of monolithic construction, servomotor 2 and ball screw installation bearing 3 are installed, and cover 6 in the outer end installation bearing pre-tightened adjustment of ball screw installation bearing 3 with ball screw mount pad 5.
In the prior art; Ball screw is installed bearing 3 and servomotor 2 are installed; Be to adopt different mount pads to install; Axiality has just directly influenced the axiality of ball screw 1 with servomotor 2 between two mount pads, is difficult to be guaranteed with regard to the axiality that has caused ball screw 1 and servomotor 2 like this.And the present invention adopts the mount pad of monolithic construction to come to install simultaneously ball screw bearing 3 and servomotor 2 are installed, because mount pad is a monolithic construction, and the axiality of two installation sites of assurance that therefore can be easily and effectively.
