The ball screw is connected onto a saddle of the lathe by a bearing, the servo motor is fixed onto a motor base, the motor base is fixed onto the saddle by the aid of a positioning block, the transmission mechanism consists of a gear, an pinion and a main gear, the gear is fixed onto one end of the ball screw by the aid of a flat key, the pinion is sleeved on the gear, and the main gear is fixedly connected onto a driving shaft of the servo motor and meshed with the gear and the pinion. The novel connection structure has the advantages of simple structure, simplicity in operation and fine transmission synchronism.

Description

A kind of novel numerically controlled lathe ball screw and motor draw bail
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 and motor draw bail.
Background technology
In a lot of medium and small machining enterprise,, often need make engine lathe into numerically controlled lathe for enhancing productivity and the machining accuracy of product; This just relates to how to connect X shaft ball screw and X axle servomotor; At present, most of enterprises all are that the machine tool accuracy of this connection is difficult to reach the required precision of Digit Control Machine Tool with the form of axle sleeve with motor and ball screw employing direct connection; And the setting height(from bottom) of motor is higher, and the processing diameter of lathe is restricted.
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 and motor draw bail 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 and motor draw bail comprise ball screw, servomotor and transmission mechanism, it is characterized in that: ball screw is connected through bearing on the saddle of lathe, and servomotor is fixed on the motor cabinet; Motor cabinet is fixed on the saddle through locating piece;
Described transmission mechanism comprises gear, pinion, master gear; Gear adopts flat key to be fixed on the end of ball screw; Pinion is sheathed on the gear; Master gear is fixedly connected on the driving shaft of servomotor; Described master gear is meshed with gear and pinion.
Adopt the tapering finger setting to be connected between described gear and the pinion.
Bolt is connected with latch segment on the described master gear; Be provided with coning sleeve between latch segment and the master gear.
The utility model links no gap and the ball screw of servomotor between master gear and gear and pinion; Guaranteed the synchronism that servomotor transmission and ball screw rotate; So just can improve the machining accuracy of lathe; And servomotor can be installed under the saddle plane, and the processing diameter of lathe can not be affected.
In sum, novel numerically controlled lathe ball screw and motor draw bail that the utility model is that a kind of structural design is simple, operating maintenance is convenient, practical.
Description of drawings
Fig. 1 the utility model structural representation.
The specific embodiment
Combine accompanying drawing at present, the utility model specific embodiment be detailed:
As shown in Figure 1; A kind of novel numerically controlled lathe ball screw and motor draw bail; Comprise ball screw 1, servomotor 7 and transmission mechanism, it is characterized in that: ball screw 1 is connected through bearing 13 on the saddle 12 of lathe, and servomotor 7 is fixed on the motor cabinet 11; Motor cabinet 11 is fixed on the saddle 12 through locating piece 2;
Described transmission mechanism comprises gear 4, pinion 5, master gear 10; Gear 4 adopts flat key 3 to be fixed on the end of ball screw 1; Pinion 5 is sheathed on the gear 4; Master gear 10 is fixedly connected on the driving shaft of servomotor 7; Described master gear 10 is meshed with gear 4 and pinion 5.
Adopt tapering pin 6 to be located by connecting between described gear 4 and the pinion 5.
Bolt is connected with latch segment 8 on the described master gear 10; Be provided with coning sleeve 9 between latch segment 8 and the master gear 10.
The utility model links no gap and the ball screw 1 of servomotor 7 between master gear 10 and gear 4 and pinion 5; Guaranteed the synchronism that servomotor 7 transmissions and ball screw 1 rotate; So just can improve the machining accuracy of lathe; And servomotor 7 can be installed under saddle 12 planes, and the processing diameter of lathe can not be affected.
The utility model is when installing gear; In order to guarantee the synchronous of servomotor 7 and ball screw 1 transmission; This just need be when mounted with gear 4 and pinion 5 turn-ofves one low-angle, and with 6 lockings of tapering pin, the transmission between master gear 10, gear 4, the pinion 5 will become gapless transmission so then; Guarantee the transmission accuracy of lathe, promptly guaranteed the machining accuracy of lathe.
