On the ball screw in the bearing block outside, be socketed with spacer, on spacer, be socketed with bearing (ball) cover, on the ball screw in the spacer outside, be bolted with round nut; Spacer sleeve is connected to two bearings on the ball screw of bearing block inside, is socketed with cone spacer on the ball screw between two bearings, is connected to outer ring spacer in the cone spacer outer cover.
The present invention can guarantee the precision of horizontal transmission, guarantees that workpiece bores the shape and size precision of milling face, the serviceability and the life-span of having improved lathe greatly.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a vertical view of the present invention.
Fig. 3 is the enlarged drawing of A part among Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly is made of parts such as servomotor 1, reductor 2, yielding coupling 3, reductor mount pad 4, round nut 5, bearing (ball) cover 6, spacer 7, outer ring spacer 8, cone spacer 9, bearing block 10, ball screw 11, nut seat 12, line slideway 13, oblique installing plate 14 and slide blocks 15.
The horizontal transmission mechanism of this numerical control drilling-milling bed is included in hard-wired reductor mount pad 4 on the oblique installing plate 14, and reductor 2 is installed on reductor mount pad 4, tiltedly is being installed with servomotor 1 on the installing plate 14, and servomotor 1 is connected with reductor 2; Fixed intervals are equipped with bearing block 10 on oblique installing plate 14, are rotatablely equipped with ball screw 11 at bearing block 10, are bolted with nut seat 12 on the ball screw between the bearing block 10 11; The parallel line slideway 13 that is equipped with all slidely connects two slide blocks 15 on every line slideway 13 on the oblique installing plate 14 of ball screw 11 both sides; Yielding coupling 3 is installed on the output shaft of described reductor 2, and an end of ball screw 11 is connected with yielding coupling 3.
On the ball screw 11 in bearing block 10 outsides, be socketed with spacer 7, on spacer 7, be socketed with bearing (ball) cover 6, on the ball screw 11 in spacer 7 outsides, be bolted with round nut 5; Spacer sleeve is connected to two bearings on the ball screw 11 of bearing block 10 inside, is socketed with cone spacer 9 on the ball screw 11 between two bearings, is connected to outer ring spacer 8 in cone spacer 9 outer cover.
When the present invention installed: servomotor 1 linked with reductor 2, reductor 2 is installed on the reductor mount pad 4, ball-screw 11 connects by yielding coupling 3 then, two side bearing installation ends of ball screw assembly, 11 are equipped with each a pair of angular contact ball bearing, there are outer ring spacer 8 and cone spacer 9 to separate between angular contact ball bearing, round nut 5 by the thread connection on the ball-screw 11 to compress spacer 7, spacer 7 compresses angular contact ball bearing again, angular contact ball bearing is fixed in the bearing block 10, bearing (ball) cover 6 is fixed on the bearing block 10 by screw, the screw of ball-screw 11 is fixed on the nut seat 12 by screw, line slideway 13 is fixed on by screw on the installed surface of oblique installing plate 14, and the main shaft mount pad is by screw and nut seat 12, slide block 15 connects.
