Multiple foots pad 9 are set the bottom even of pedestal 1, and base rail 2 and lathe bed 3 are fixedly installed on pedestal 1.Base rail 2 is
Two closed slides, same one end of two parallel base guide rails is respectively provided with a servo longitudinal motor, and (not shown in figure, longitudinal direction is Fig. 1
In perpendicular to paper direction), be respectively provided with a screw mandrel on the top of two parallel base guide rails, one end and the servo longitudinal motor of screw mandrel
Rotary shaft be connected, the bottom of two columns 10 is respectively fixedly connected by sliding block with feed screw nut, in the outside of two base rails 2
On along longitudinal direction respectively set a graduated scale.Column guide rail is respectively provided with the side of two columns 10, back timber 7 is arranged on by sliding block
On column guide rail, a support 11 is respectively provided with the outside of two columns, the bottom of support 11 is fixed with reinforcement, each support 11
A hoist cylinder 12 is fixedly installed respectively, the piston rod of hoist cylinder 12 is connected with back timber 7, can drive and be moved down on back timber 7
It is dynamic.Being horizontally disposed with back timber 7 has convex guide rail and ball screw, and ball screw is driven by the first servomotor installed in right-hand member,
Slide is installed, the slide back side is installed with nut seat, and nut seat is enclosed on the ball screw nut of back timber 7 solid on convex guide rail
Fixed connection, when the first servomotor drive screw is rotated, feed screw nut drives slide left and right horizontal movement on back timber 7.It is sliding
The recessed guide rail and ball screw of vertical direction are housed, the second servomotor 8 is arranged on slide upper end, in the recessed guide rail of slide on seat
On main spindle box slide unit is installed, the main spindle box slide unit back side is installed with nut seat, and nut seat is enclosed on the ball screw on slide
It is fixedly connected on nut, when the drive screw of the second servomotor 8 is rotated, feed screw nut drives the upper and lower vertical fortune of main spindle box slide unit
It is dynamic.It is provided with main spindle box slide unit inside spindle motor 6, replaceable main spindle box 5 and tool heads 4, replaceable main spindle box 5 along vertical
Direction is disposed with power transmission shaft, the first main shaft and the second main shaft, and replaceable main spindle box 5 is provided with right on upper and lower end plate, upper and lower end plate
