The utility model compared with prior art has the following advantages:
1) the utility model has separated the Y-axis motion of workbench, makes workbench only be related to motion with X, has cancelled the constraint of cross slide plate, and the workbench dynamic response is better, and it is very big that the carrying of work can be done, and satisfied the demand of heavily loaded vertical machining centre.
2) Y is realized by column to motion, and original relatively cross slide plate and workpiece weight have reduced the defect of vibrating during cutting, improved machining accuracy.
3) the occupation of land space of post movable machining center is littler, and is nearer apart from main shaft simultaneously for the operator, is convenient to the clamping of workpiece.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the A portion enlarged diagram of Fig. 2.
The specific embodiment
Referring to Fig. 1～Fig. 3, post movable vertical machining centre of the present utility model comprises bed piece 1, workbench 2, column 3, main spindle box 4.
Described lathe bed 1 is a T type structure, lathe bed 1 transversely be provided with X to for workbench 2 be X to the motion first guide rail 5, lathe bed 1 vertically be provided with Y to do second guide rail 6, three guide rail 7 of Y for column to motion, this second, third guide rail 6,7 is respectively line rail, hard rail.
Workbench 2 is connected with first guide rail 5 on the lathe bed 1 by linear slide rail piece 21; Table-driving mechanism 8 is arranged on the lathe bed 1, comprises the motor 82 of X-axis leading screw 81, nut and driving X-axis leading screw; X-axis leading screw 81 is connected with workbench 2 by the nut on it, is X to motion thereby drive X-axis leading screw 81 driving workbench 2 by motor 82.
