Background technology
Along with the continuous progress of Digit Control Machine Tool art, the important component part of Digit Control Machine Tool---numerical control rotating platform is just higher towards precision, the better future development of precision stability.For realizing above-mentioned performance, two helical pitch worm couples have been applied to this field widely, and the feature of this structure " gap can compensate " makes the precision of Digit Control Machine Tool and precision stability rise to new height.But because this structure is pure sliding friction, in use for some time, will inevitably cause the increase of worm couple back lash because of wearing and tearing, thereby have a strong impact on the precision of numerical control rotating platform, cause the shutdown maintenance of whole lathe.
At present due to the complex structure of numerical control rotating platform production firm design, adjust loaded down with trivial detailsly, user is cannot accurate quantitative analysis given for backlash compensation amount.Current, the clearance compensation adjusting Dou Shiyou professional and technical personnel of production firm of two helical pitch worm couples adjusts, and adopts after the dismounting of worm shaft system, measure each accessory size, then adjustment pad is taken off, after grinding machine, ressemble, waste time and energy, and often cause to produce and incur loss through delay.Therefore how quick and precisely to compensate worm couple back lash, become a difficult problem of lying across in face of numerous users.Therefore being badly in need of a kind of technology can address the above problem, and efficiently implements fast compensation when having accurate compensated setpoint amount concurrently.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of accurate compensated setpoint amount the efficient quick compensator of implementing two helical pitch worm and gear auxiliary air gaps of compensation.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: the blank compensation apparatus of a kind of pair of helical pitch worm couple, comprise numerical control rotating platform housing, worm gear and double pitch worm, between described worm gear and double pitch worm, be connected with a joggle, its special character is, described double pitch worm is radially fixed in needle bearing II, and described needle bearing II is axially fixed in described numerical control rotating platform housing by circlip for hole I and circlip for hole II; Described double pitch worm is provided with by the radially fixing adjusting sleeve of needle bearing I with by the adjusting sleeve of combination locking nut, thrust ball bearing I axial restraint; Between described double pitch worm and adjusting sleeve, be provided with thrust ball bearing II; Between described adjusting sleeve and numerical control rotating platform housing, leave gap delta.
The beneficial effects of the utility model are: the utility model is cancelled the adjustment pad in original structure, to between adjusting sleeve and numerical control rotating platform housing, leave gap delta, rotation adjusting sleeve is also used worm screw fastening by the interlocked of retaining ring, can compensate rapidly and accurately two helical pitch worm and gear auxiliary air gaps, convenient to operation, time saving and energy saving, have advantages of that accuracy is high, reliability is strong.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described combination locking nut is fixed on described double pitch worm by screw thread, forms interlocking connect by set screws IV.

The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
The blank compensation apparatus of a kind of pair of helical pitch worm couple, comprise numerical control rotating platform housing 19, worm gear 20 and double pitch worm 14, between described worm gear 20 and double pitch worm 14, be connected with a joggle, its special character is, described double pitch worm 14 is radially fixed in needle bearing II 16, and described needle bearing II 16 is axially fixed in described numerical control rotating platform housing 19 by circlip for hole I 15 and circlip for hole II 17; Described double pitch worm 14 is provided with by the radially fixing adjusting sleeve 4 of needle bearing I 12 with by the adjusting sleeve 4 of combination locking nut 5, thrust ball bearing I 9 axial restraints; Between described double pitch worm 14 and adjusting sleeve 4, be provided with thrust ball bearing II 13, between described adjusting sleeve 4 and numerical control rotating platform housing 19, leave gap delta.
Further, described combination locking nut 5 is fixed on described double pitch worm 14 by screw thread, forms interlocking connect by set screws IV 6.
Described adjusting sleeve 4 is controlled axial location by retaining ring I 7, retaining ring II 10.
Described retaining ring I 7, retaining ring II 10 are fixedly connected on described numerical control rotating platform housing 19 by set screws II 8, set screws III 11 respectively, and described set screws II 8 is through described retaining ring II 10.
Between described double pitch worm 14 and described numerical control rotating platform housing 19, be provided with outside framework oil seal 18.
On described numerical control rotating platform housing 19, by set screws I 1, be fixedly connected with end cap 3 and sealing ring 2.
The utility model is to use like this, NC rotary table was used after a period of time, because wearing and tearing will make to produce gap between two helical pitch worm couples, now adopt amesdial by suitable, counterclockwise turn workbench, to record actual gap λ in T-shaped groove of working table side; According to the pitch P of the tight right-handed thread at adjusting sleeve 4 cylindrical places, and double pitch worm 14 thicken COEFFICIENT K, according to following formula, calculate the angle that adjusting sleeve 4 needs rotation:
Adjusting sleeve 4 clockwise turns to and reduces gap, is rotated counterclockwise as increasing gap.
Unclamp set screws I 1, end cap 3 and sealing ring 2 are unloaded; Unclamp set screws II 8, unload retaining ring I 7, the word open slot 21 now arranging by adjusting sleeve 4 end faces, utilizes instrument rotation adjusting sleeve 4, according to the θ value of calculating gained above, rotates corresponding angle; When rotation adjusting sleeve 4, drive and be connected and fixed combination locking nut 5, set screws IV 6, thrust ball bearing I 9, needle bearing I 12, thrust ball bearing II 13 and the double pitch worm 14 being integrated with it, owing to being reserved with gap delta between the step of adjusting sleeve 4 and the step of numerical control rotating platform housing 19, whole worm shaft is by axial float, tooth portion thicker on double pitch worm 14 is dropped into and worm gear 20 engagements, compensated the gap increasing because of wearing and tearing.After backlash compensation completes, retaining ring I 7 is reinstalled, due to the interlocked use of retaining ring I 7 and retaining ring II 10, the axial location of worm shaft system will be fixed, and finally end cap 3 and sealing ring 2 be loaded onto, and once adjust complete.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
