Abstract

A fixed workbench structure for electro discharge sinking machines, which comprises a base, a workbench, a Z coordinate and a main spindle box, wherein the Z coordinate is connected with a ball screw; the Z coordinate is inserted into main spindle box through a Z coordinate straight-line guide rail pair; the utility model also contains an upper saddle, a middle saddle and a lower saddle, wherein ball screws are installed at the bottom of both the upper saddle and the middle saddle; the upper saddle is positioned right above the middle saddle; the upper saddle and the middle saddle are socketed through the Y coordinate straight-line guide rail pair; the middle saddle is positioned above the lower saddle; the middle saddle and the lower saddle are socketed through the X coordinate straight-line guide rail pair; the main spindle box is fixed right in front of the upper saddle; the lower saddle is fixed on the base, right behind the workbench; the workbench is fixed on the base. Capable of improving the processing accuracy as well as the follow-up sensitivity of X- and Y-coordinate movements, the utility model can thoroughly solve the technical problem that accuracy can hardly be controlled when the workbench moves to horizontal and vertical limit positions.

Description

The fixed work bench face structure of spark-erosion sinking machine
Technical field
The utility model relates to the fixed work bench face structure of spark-erosion sinking machine, is mainly used in three-axis numerical control spark-erosion sinking machine and six Shaft and NC Machining Test spark-erosion sinking machines.
Background technology
What present domestic spark-erosion sinking machine mainly adopted is the frame for movement of cross table type, and the side-to-side movement of workbench is the X-axis motion, and seesawing of workbench is the Y-axis motion.The advantage of this structure is: simple in structure, easy to operate.But there are two significant disadvantages: (1), when the workbench excessive time influence processing sensitivity of bearing a heavy burden.(2), at workbench in length and breadth to when motion, owing to be subjected to factor affecting such as workpiece weight, moment, lathe rigidity, the kinematic accuracy of lathe changes greatly, especially when arriving near the both positive and negative polarity extreme position when working table movement, the variation phenomenon of precision is particularly evident, can't satisfy the specification requirement of high-end user.
Summary of the invention
The purpose of this utility model provides a kind of fixed work bench face structure of spark-erosion sinking machine of the servo sensitivity that can improve machining accuracy and X, Y-axis motion.
The technical scheme that realizes above-mentioned purpose is: a kind of fixed work bench face structure of spark-erosion sinking machine, comprise base, workbench, Z axle and main spindle box, be connected with ball screw on the Z axle, Z axle and main spindle box are pegged graft by Z axle line slideway auxiliary, also comprise upper saddle, middle slide and lower slider, the bottom of upper saddle and middle slide all is equipped with ball screw, upper saddle be arranged in slide directly over, and upper saddle and middle slide adopt the Y-axis line slideway auxiliary to peg graft, middle slide is positioned at the top of lower slider, and middle slide and lower slider adopt the X-axis line slideway auxiliary to peg graft, main spindle box is fixed on the dead ahead of upper saddle, lower slider is fixed on the base, and lower slider is positioned at the dead astern of workbench, and stationary table is installed on the base.
After adopting technique scheme, lower slider all is fixedly connected on the base, the bottom of upper saddle and middle slide all is equipped with ball screw, upper saddle be arranged in slide directly over, and upper saddle and middle slide adopt the Y-axis line slideway auxiliary to peg graft, middle slide is positioned at the top of lower slider, and middle slide and lower slider adopt the X-axis line slideway auxiliary to peg graft, the ball screw transmission is adopted in upper saddle and the motion of middle slide, the ball screw transmission is also adopted in the motion of Z axle, and the side-to-side movement of middle slide is the X-axis motion, and seesawing of upper saddle is the Y-axis motion, owing to adopt the ball screw transmission, X-axis, the precision of Y-axis motion and sensitivity are all than higher.Stationary table is on base, itself does not move workbench, the motion of workbench and X-axis, Y-axis does not have direct relation, thereby the weight of workpiece does not influence the precision and the sensitivity of the motion of X, Y-axis on the workbench, has thoroughly solved the workbench uppity technical barrier of precision when moving to extreme position in length and breadth.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1, shown in 2, a kind of fixed work bench face structure of spark-erosion sinking machine, comprise base 8, workbench 9, Z axle 1-1 and main spindle box 1, workbench 9 is fixed by bolts on the base 8, be connected with ball screw on the Z axle 1-1, Z axle 1-1 and main spindle box 1 are pegged graft by Z axle line slideway auxiliary 2, also comprise upper saddle 3, middle slide 5 and lower slider 7, upper saddle 3 and middle slide 5 bottoms all are equipped with ball screw, upper saddle 3 be arranged in slide 5 directly over, and upper saddle 3 adopts Y-axis line slideway auxiliary 4 to peg graft with middle slide 5, and middle slide 5 is positioned at the top of lower slider 7, and middle slide 5 adopts X-axis line slideway auxiliary 6 to peg graft with lower slider 7, main spindle box 1 is fixed on the upper saddle 3, lower slider 7 is fixed by bolts to the dead ahead of base 8, and lower slider 7 is positioned at the dead astern of workbench 9, and workbench 9 is fixed by bolts on the base 8.
