Abstract
The invention discloses a spindle box gravity center balancing device of a boring-milling machine, and relates to the technical field of machine tool manufacturing. The device comprises a spindle box and a stand column; the spindle box is provided with a front balance chain and a rear balance chain; one end of the front balance chain is connected with a piston rod of a balance compensation oil cylinder in the spindle box; the other end of the front balance chain is connected with a balance balancing weight in the stand column through a front balance chain pulley; one end of the rear balance chain is connected with the spindle box, and the other end of the rear balance chain is connected with the balance balancing weight through a rear balance chain pulley. The device can solve the problem that in the prior art, the distance between the extending position of a floor boring-milling machine ram and the spindle box is large, and the machining precision is reduced is solved.
Description
Technical field
The present invention relates to technical field of machine tool manufacture, especially a kind of device balancing boring and milling machine main spindle box center of gravity.
Background technology
Traditional numerical control floor type boring and milling machine is in process, when the positional distance main spindle box that ram stretches out is far away, because main shaft is cantilever design, now main shaft rigidity can be deteriorated, cause whole main spindle box center of gravity to change, cause numerical control floor type boring and milling machine machining accuracy to reduce.
Summary of the invention
The object of this invention is to provide a kind of boring and milling machine main spindle box gravity balance device, it can solve the distance of floor-type milling & boring machine ram extended position in prior art main spindle box far away time the machining accuracy problem that reduces.
In order to solve the problem, the technical solution used in the present invention is: this boring and milling machine main spindle box gravity balance device, comprise main spindle box, column, described main spindle box is provided with forward horizontal stand chain and back balance chain, described forward horizontal stand chain one end is connected with the piston rod of the balanced compensated oil cylinder be located in described main spindle box, and its other end is connected with the equilibrate counterweight be located in described column by forward horizontal stand chain pulley; One end of described back balance chain is connected with described main spindle box, and the other end is connected with described equilibrate counterweight by back balance chain pulley.
According to above technical scheme, further scheme is: described forward horizontal stand chain pulley and described back balance chain pulley all have two groups, are located at the top of described column respectively.
Further scheme is: described balancing cylinder is connected with the electrohydraulic proportional control valve be located in boring and milling machine hydraulic system.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, when floor-type milling & boring machine main spindle box gravity balance device can solve floor-type milling & boring machine high-rate cutting workpiece, the center of gravity of main spindle box stretches out movement due to ram, and the center of gravity of main spindle box is changed.
2, floor-type milling & boring machine main spindle box gravity balance apparatus structure is simple, convenient, practical.
3, main spindle box stretching motion linearity is better, and whole system rigidity is better.
4, the machining accuracy of floor-type milling & boring machine can be improved.
5, floor-type milling & boring machine can keep good precision, extends its service life.
Accompanying drawing explanation
Fig. 1 is boring and milling machine main spindle box gravity balance device schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described: boring and milling machine main spindle box gravity balance device as shown in Figure 1, comprise main spindle box 1 and column 7, main spindle box is provided with forward horizontal stand chain 8 perpendicular to column 7 and back balance chain 2, one end of forward horizontal stand chain 8 is connected with the piston rod of the balanced compensated oil cylinder 6 be located in main spindle box 1, and its other end is connected with the equilibrate counterweight 5 be located in column 7 by forward horizontal stand chain pulley 4; One end of back balance chain 2 is connected with main spindle box 1, and the other end is connected with equilibrate counterweight 5 by back balance chain pulley 3.
Forward horizontal stand chain pulley 4 and back balance chain pulley 3 all have two groups, are located at the top of column 7 respectively.
After implementing this boring and milling machine main spindle box gravity balance device, the pressure of balanced compensated cylinder body 6 is controlled by electro-hydraulic proportional valve, the pulling force of forward horizontal stand chain 8 and back balance chain 2 is made to produce corresponding change by the change of the pressure of balanced compensated cylinder body 6, forward horizontal stand chain 8 and the tension distributing between back balance chain 2 and main carrying chain are adjusted by equilibrate counterweight 5, and the former poised state of main spindle box 1 is maintained.
