Description
Technical field
The utility model patent relates to a kind of main axle structure, the hydrostatic spindle structure that particularly a kind of gap is adjustable.
Background technology
The gap of existing large-scale workbench main shaft and collar bush little, stressed large, lubricate insufficient, temperature rise fast, easily causes that main shaft is pulled, locking phenomenon, selects hydrostatic to solve this problem.The employing of hydrostatic requires that between workbench main shaft and collar bush, gap is minimum, and large main arbor overall dimensions is bigger than normal, processing will ensure that each size and geometric tolerances require that difficulty is larger, ensure that the probability in the gap between main shaft and collar bush is very micro-by processing completely, main shaft will be overproof with the gap of collar bush after repair for 2nd time, cause main shaft material to give up, loss greatly.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned technology, provides a kind of hydrostatic spindle structure that can adjust main shaft and collar bush fit clearance.
The purpose of this utility model is achieved in that
The hydrostatic spindle structure that a kind of gap is adjustable, it comprises hydrostatic spindle, static pressure tapered sleeve matches with hydrostatic spindle, it is characterized in that: hydrostatic spindle is processed with male-tapered end, static pressure tapered sleeve is processed with inner conical end, male-tapered end and inner conical end form tapering matched in clearance, and static pressure tapered sleeve, adjusting pad are fixedly connected with formation overall structure with worm-wheel bracket by screw, and hydrostatic spindle is fixedly linked by attachment screw and table base.
The overall structure of described static pressure tapered sleeve, adjusting pad, worm-wheel bracket composition rotates relative to hydrostatic spindle.
Described hydrostatic spindle is respectively equipped with oil-in and oil-out.
The tapering matched in clearance face of described hydrostatic spindle and described static pressure tapered sleeve defines static-pressure oil chamber.
The fit clearance of hydrostatic spindle and static pressure tapered sleeve can be adjusted by the thickness changing adjusting pad.
The utility model has following beneficial effect:
The hydrostatic spindle employing outer cone that a kind of gap that the utility model provides is adjustable is formed with the inner cone of static pressure tapered sleeve and coordinates, static pressure tapered sleeve relative static pressure main shaft can be made to move up and down by the thickness of adjusting pad below adjustment static pressure tapered sleeve, increase or reduce fit clearance, thickness when major axis size is overproof by changing adjusting pad adjusts fit clearance, effectively prevent temperature and raise the hydrostatic spindle and static pressure tapered sleeve locking phenomenon that cause, effectively prevent the generation that main shaft material is useless, reduce the loss and greatly saved cost, also bring conveniently to assembling simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is integral installation distribution structure schematic diagram of the present utility model.
Fig. 2 is hydrostatic spindle structural representation of the present utility model.
In figure: hydrostatic spindle 1, static pressure tapered sleeve 2, adjusting pad 3, worm-wheel bracket 4, table base 5, attachment screw 6, oil-in 7, oil-out 8, screw 9, static-pressure oil chamber 10.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
See Fig. 1-2, installation concrete in figure and connected mode have, the hydrostatic spindle structure that a kind of gap is adjustable, it comprises hydrostatic spindle 1, static pressure tapered sleeve 2 matches with hydrostatic spindle 1, hydrostatic spindle 1 is processed with male-tapered end, static pressure tapered sleeve 2 is processed with inner conical end, male-tapered end and inner conical end form tapering matched in clearance, static pressure tapered sleeve 2, adjusting pad 3 are fixedly connected with formation overall structure with worm-wheel bracket 4 by screw 9, and hydrostatic spindle 1 is fixedly linked by attachment screw 6 and table base 5.
See Fig. 1, the overall structure of described static pressure tapered sleeve 2, adjusting pad 3, worm-wheel bracket 4 composition rotates relative to hydrostatic spindle 1.
See Fig. 1, described hydrostatic spindle 1 is respectively equipped with oil-in 7 and oil-out 8.
See Fig. 1, described hydrostatic spindle 1 and the tapering matched in clearance face of described static pressure tapered sleeve 2 define static-pressure oil chamber 10.
Preferably, the thickness by changing adjusting pad 3 can adjust the fit clearance of hydrostatic spindle 1 and static pressure tapered sleeve 2.
Device specific works process of the present utility model and principle are:
The outer cone of hydrostatic spindle 1 coordinates with the inner conical tapering of static pressure tapered sleeve 2, the thickness of adjusting pad is calculated by the fit clearance size of the excircle dimension of actual measurement, tapering size, demand when hydrostatic spindle 1 dimension overproof, making static pressure tapered sleeve 2 relative static pressure main shaft 1 moves or moves down by changing adjusting pad 3, meeting fit clearance requirement.
