The novel structure for bearing the ball screw of the numeric-control lathe has the advantages of simple structure, simplicity in operation, and good transmission synchronicity.
Description
Technical field
The utility model relates to the numerically controlled lathe apparatus field, refers more particularly to a kind of novel numerically controlled lathe ball screw supporting structure.
Background technology
In a lot of medium and small machining enterprise; For enhancing productivity and the machining accuracy of product, often need make engine lathe into numerically controlled lathe, this just relates to and how the Z shaft ball screw is supported; At present; Most of enterprises support at two of ball screw with bearing, and this supporting is owing to receive the restriction of ball wire rod dress and length, the installation negligible amounts of bearing; Machine tool accuracy is difficult to reach the required precision of Digit Control Machine Tool, and the long repacking cost that has also increased lathe of screw mandrel length.
The utility model content
The purpose of the utility model is to overcome above-mentioned weak point of the prior art and a kind of simple in structure, simple to operate, novel numerically controlled lathe ball screw supporting structure that the transmission synchronism is good, practical is provided.
The utility model is realized through following mode:
A kind of novel numerically controlled lathe ball screw supporting structure is characterized in that: include servomotor, axle, ball screw and link gear; Servomotor is fixed on the motor cabinet; Motor cabinet is installed on the lathe bed of lathe, and servomotor is connected with axle through flexible coupling, and axle is connected with an end of ball screw through coupling band; The other end of ball screw is connected on the carriage through bearing; Carriage is fixedly connected on the lathe bed;
Described link gear comprises left bearing, right bearing, locating piece; Locating piece is sheathed on the axle; Locating piece is fixed on the motor cabinet; The both sides dress of locating piece respectively is provided with little bearing, and little bearing holder (housing, cover) is located on the axle; Left bearing is sheathed on the axle, and is positioned at the left side of little bearing; Right bearing is sheathed on the axle, and is positioned at the right side of little bearing; Be provided with cushion collar between left bearing, right bearing and the little bearing; It is fastening that the left side of left bearing is provided with nut; The outer end of right bearing is provided with bearing holder (housing, cover); Bearing holder (housing, cover) is fixed on the motor cabinet.
Described coupling band is fixedly connected with axle employing tapering pin.
The utility model is utilizing axle and ball screw to link; The installation site that axle can be processed into several bearings on request; The supporting of ball screw is more firm like this, can improve the machining accuracy of lathe, and the length of ball screw can be designed to short form; Also just can reduce the price of ball screw, thereby reduce the retrofit of machine tools cost.
In sum, the novel numerically controlled lathe ball screw supporting structure that the utility model is that a kind of structural design is simple, operating maintenance is convenient, practical.
