Abstract
The utility model discloses a machine tool balance supporting automatic aligning device and relates to the technical field of machine manufacturing. The machine tool balance supporting automatic aligning device comprises a supporting base. One end of the supporting base is connected with a lifting main shaft box. The other end of the supporting base is connected with a boss at the end of a piston rod. The connection portion of the boss at the end of the piston rod and the supporting base is provided with an upper self-aligning spherical washer and a lower self-aligning spherical washer in a sleeved mode. The plane of the lower self-aligning spherical washer is in contact with the supporting base. The protruding spherical face of the lower self-aligning spherical washer is in contact with the concave spherical face of the upper self-aligning spherical washer. The upper self-aligning spherical washer which is arranged at the end of the piston rod boss in a sleeved mode is locked by a locking nut. According to the machine tool balance supporting automatic aligning device, the problems that after a hydraulic balance mechanism is assembled, the form and location tolerance of a machine tool is large, so that machine tool accuracy is poor, an assembling cycle is prolonged, and production cost is increased can be solved.
Description
Technical field
The utility model relates to plant equipment manufacturing technology field, especially a kind of device for the vertical hydro-cushion supporting of lathe automatic capturing.
Background technology
Current domestic manufacture, sale and use, for Digit Control Machine Tool or the supporting vertical elevating movement case of machining center, for ensureing the service life of screw mandrel and the movement sensitive of lathe, can use hydro-cushion supporting device, because hydro-cushion supporting is to be contained on two parts that mutually move, there is rigging error to produce.There is following defect: 1, make the damping of the catenary motion of lathe increase, machine tool accuracy is exerted an influence; 2, increased assembly period; 3, high to the form and position tolerance processing request of part, cost increases.
Utility model content
The purpose of this utility model is to provide a kind of lathe balanced support automatic centering device, and it can solve lathe and cause greatly machine tool accuracy poor and increase the problem of assembly period and production cost because of form and position tolerance after Hydraulic Equilibrium Mechanism assembling.
In order to address the above problem, the technical solution adopted in the utility model is: this lathe balanced support automatic centering device, includes supporting base; One end of described supporting base is connected with lifting main spindle box, and the other end is connected with the boss of the piston rod end in oil cylinder, and the cylinder body of described oil cylinder is fixedly mounted on the slide of described lifting main spindle box; The boss of described piston rod end and described supporting base junction are set with from centering spherical washer and lower to centering spherical washer; Described upper is plane from a side of centering spherical washer, another side is protruding sphere, is plane from a side of centering spherical washer under described, another side is concave spherical surface; Plane from centering spherical washer under described contacts with described supporting base, above contacts from the concave spherical surface of centering spherical washer under described from the protruding sphere of centering spherical washer with described; Being enclosed within the described upper of described piston rod boss termination is locked by locking nut from centering spherical washer.
In above technical scheme, more specifically scheme is: described supporting base is connected with lifting main spindle box with pin by bolt.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the utility model props up and is housed on two relative movement parts because of hydro-cushion, and in the time having error to produce, spherical washer energy automatic capturing, has reduced the impact impaired on machine tool accuracy;
2, the utility model versatility is wide, can on multiple Digit Control Machine Tool, apply;
3, the utility model can improve the reliability of the lifting precision of lathe, good cost performance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Number in the figure is expressed as: 1, lifting main spindle box; 2, supporting base; 3, locking nut; 4, upper from centering spherical washer; 5, under from centering spherical washer; 6, piston rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The lathe balanced support automatic centering device of Fig. 1; Include supporting base 2; One end of supporting base 2 is connected with lathe lifting main spindle box 1 with pin by bolt, and the other end is connected with the boss of piston rod 6 ends in oil cylinder, and the cylinder body of described oil cylinder is fixedly mounted on the slide of described lifting main spindle box 1; The boss of piston rod 6 ends and supporting base 2 junctions are set with from centering spherical washer 4 and lower to centering spherical washer 5; Upper is plane from a side of centering spherical washer 4, and another side is protruding sphere, under be plane from a side of centering spherical washer 5, another side is concave spherical surface; Under contact with supporting base 2 from the plane of centering spherical washer 5, under contact with the upper concave spherical surface from centering spherical washer 4 from the protruding sphere of centering spherical washer 5; Be enclosed within upper locking by locking nut 3 from centering spherical washer 4 of piston rod 6 boss terminations.
When lathe lifting main spindle box 1 moves up and down, piston rod 6 by upper from centering ball pad compared with 4, under support from centering spherical washer 5 supporting base 2 being connected with lifting main spindle box 1, hydro-cushion is propped up and is housed on two relative movement parts, upper from centering spherical washer 4 while having error to produce, under from centering spherical washer 5 automatic capturings, be equivalent to a mechanical activity joint, in moving up and down, keeping at any time the dynamic vertical with lifting main spindle box 1 line of motion, reach to solve because of hydro-cushion and prop up and be housed in spherical washer automatic capturing while having error produce on two relative movement parts, reduce the object impaired to machine tool accuracy.
