Abstract
The utility model discloses an expansible mandrel is used in processing of thin wall sleeve part, wherein: have a mandrel of centre bore including both ends, one side of mandrel is fixed with first taper sleeve, and the opposite side cover is equipped with the relative second taper sleeve that sets up with first taper sleeve, and the cover being equipped with the cover that expands between first, two taper sleeves, the cover axial that expands is equipped with the open slot, and overlap outside the second taper sleeve and be equipped with the clamp plate, the outside end of mandrel has the screw thread, and the nut compresses tightly the clamp plate with screw -thread fit. Support thin wall part that can be fine, thin wall cover PARTS DEFORMED are rateed and are reduced by a wide margin, and the grinding time also shortens greatly, has improved product quality promptly, has improved production efficiency again.
Description
Technical field
The utility model belongs to equipment manufacturing field.Be specifically related to a kind of thin-wall sleeve parts processing expanding arbor mainly used when thin-wall sleeve parts cylindricalo grinding.
Background technology
A lot of thin-wall sleeve parts is all contained in numerous parts such as transmission case body, travelling block, winch, rotating disk of oil-well rig.The thin-wall sleeve cylindrical of considerable part coordinates with potted component, and these thin-wall sleeve majority required precisions are to foreign round higher, once distortion very easily causes poorly sealed and leakage of oil, has very large impact to the quality of product and manufacturing schedule.Existing processing tool is sleeved on the axle adapted to process, and because sleeve and part have certain interval, in process, thin-walled parts is yielding.
Summary of the invention
For solving the above-mentioned defect that prior art exists, the purpose of this utility model is to provide a kind of thin-wall sleeve parts processing expanding arbor, can be good at supporting thin-walled parts; Thin-walled part deformation rate significantly reduces; the grinding time also shortens greatly; namely improve product quality, turn improves production efficiency.
The technical scheme adopted: this thin-wall sleeve parts processing expanding arbor, it is characterized in that: comprise the axle that there is centre bore at two ends, the side of axle is fixed with the first tapered sleeve, opposite side is set with the second tapered sleeve be oppositely arranged with the first tapered sleeve, between first and second tapered sleeve, be set with expansion set, described expansion set is axially arranged with open slot, outside the second tapered sleeve, be set with pressing plate, the outboard end of described axle has screw thread, nut and threaded engagement clamping platen.
Adopt the beneficial effect of technique scheme: this expanding arbor mainly uses when thin-wall sleeve parts cylindricalo grinding, is made up of axle (there is centre bore at two ends), expansion set, tapered sleeve, pressing plate, nut etc.Minor axis thin-wall sleeve expanding arbor by, expansion set, pressing plate, nut form.During use, only need unscrew nut, Thin-walled part is overlapped upper spindle; Then fastening nut, the pressure of nut by pressing plate function on expansion set, because expansion set produces uniform distortion and stretching inner hole of workpiece at circumferencial direction.Top top is used at axle two ends, and driving lever drives axle and workpiece to rotate.In actual production process, the comparatively close thin-wall sleeve of internal diameter can share the remainder except expansion set, and the thin-wall sleeve of different-diameter only need change expansion set.The installation positioning precision of processing work is ensured by the axiality controlled between expansion set cylindrical and spindle center hole.Meanwhile, owing to there is not gap between workpiece concentric shafts locating surface, the position error of workpiece is considerably reduced; And thin-wall sleeve is uniform force in compaction process, therefore avoid the distortion of thin-wall sleeve.Use through reality, Thin-walled part deformation rate significantly reduces, and the grinding time also shortens greatly, namely improves product quality, turn improves production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, specific embodiment of the utility model is further described in detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This thin-wall sleeve parts processing expanding arbor as shown in Figure 1, comprise the axle 1 that there is centre bore at two ends, the side of axle is fixed with the first tapered sleeve 7, opposite side is set with the second tapered sleeve 3 be oppositely arranged with the first tapered sleeve, between first and second tapered sleeve, be set with expansion set 2, described expansion set is axially arranged with open slot, is set with pressing plate 4 outside the second tapered sleeve, the outboard end of described axle has screw thread, nut 5 and threaded engagement clamping platen.In actual production process, workpiece 6 is sleeved on expansion set 2, and by the compression of nut 5 pairs of pressing plates 4, tapered sleeve outwards supports expansion set 2, makes expansion set 2 can be good at work 6 and contacts compression, thus realize the grinding to work 6.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
