Abstract
The utility model provides a gear hobbing clamp of an internal spline gear. The gear hobbing clamp comprises a base, a location disc fixed on the base and a mandrel installed on the base. The mandrel penetrates through the location disc in gap mode, the upper end face of the location disc is perpendicular to the axis of the mandrel, and a press plate is movably sleeved on the mandrel. The gear hobbing clamp is characterized in that the mandrel is provided with a smooth section, an external spline conical sleeve is sleeved on the smooth section of the mandrel, an inner round hole of the external spline conical sleeve is in gap fit with the smooth section of the mandrel, and the external conical face of the external spline conical sleeve is in interference fit with an inner spline of the inner spline gear, so that the gap between the mandrel and the inner spline gear is reduced, clamping accuracy is improved, and accuracy and quality of gear portions undergoing gear hobbing are ensured.
Description
Technical field
The utility model relates to the anchor clamps of gear, relates in particular to a kind of gear hobbing anchor clamps of inside spline wheel gear.
Background technology
The gear hobbing anchor clamps of inside spline wheel gear comprise mandrel at present; Mandrel is provided with the external splines that matches with the internal spline of inside spline wheel gear; In inside spline wheel gear gear hobbing process, inside spline wheel gear is installed in realizes the clamping location on the external splines of mandrel, but there are two conflicting difficult points in it; As be simple, convenient; Promptly guarantee the inside spline wheel gear mandrel of packing into smoothly, mandrel with the cooperating of the big footpath of internal spline of inside spline wheel gear must get bigger matched in clearance, when gear hobbing, probably cause excessive offset (center, the big footpath of actual internal spline of product do not overlap and distance excessive) like this with the gear teeth center of processing; Tooth portion precision when causing gear hobbing is defective, to such an extent as to the generation of waste product; Less like the matched in clearance design on the other hand, the processing offset is little, but clamping is very difficult, and the workman is when loading and unloading, and inside spline wheel gear damages easily.
The utility model content
The technical problem that the utility model solves is: a kind of gear hobbing anchor clamps of inside spline wheel gear are provided, can reduce the gap between gear hobbing anchor clamps and the processed gear.
The technical scheme of the utility model is: a kind of gear hobbing anchor clamps of inside spline wheel gear; Comprise base, be fixed on the positioning disk on the base and be installed in the mandrel on the base, said positioning disk is passed in said mandrel gap, and the upper surface of positioning disk is perpendicular to the axial line of said mandrel; One pressing plate is actively set on the mandrel; It is characterized in that said mandrel has smooth section, be with the external splines tapered sleeve on the smooth section of mandrel; The interior circular hole of external splines tapered sleeve and the smooth section matched in clearance of mandrel, interference fit between the male cone (strobilus masculinus) of external splines tapered sleeve and the internal spline of inside spline wheel gear.
The middle part of said pressing plate has stepped hole, and said mandrel activity is through in the aperture of stepped hole, has clearance distance between the end face of external splines tapered sleeve and the hole of the said stepped hole shoulder.
The end of said mandrel is provided with and is used for said pressing plate is carried out spacing nut.
The beneficial effect of the utility model is: when the utility model uses; The external splines tapered sleeve is packed in the internal spline of inside spline wheel gear, the external splines tapered sleeve is enclosed within the smooth section of mandrel again, the lower surface of inside spline wheel gear is supported on the upper surface of positioning disk; Thereby the axial line that guarantees inside spline wheel gear and mandrel is perpendicular; This moment the external splines tapered sleeve interior circular hole and the smooth section interference fits of mandrel, interference fit between the male cone (strobilus masculinus) of external splines tapered sleeve and the internal spline of inside spline wheel gear, this structure have substituted the axle center in the existing structure and have been provided with external splines; The structure that matches between the internal spline of inside spline wheel gear and the external splines of mandrel; Therefore reduce the gap between mandrel and the inside spline wheel gear, improved the clamping precision, guaranteed the precision and the quality of gear hobbing tooth portion.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the external splines tapered sleeve in the utility model;
Fig. 3 is the structural representation of the pressing plate in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1～Fig. 3, a kind of gear hobbing anchor clamps of inside spline wheel gear comprise base 1, positioning disk 2, mandrel 3, pressing plate 4 and external splines tapered sleeve 5.Positioning disk 2 is fixed on the base 1 through interior hexagonal cylinder screw, and mandrel 3 is installed on the base 1, and positioning disk 2 is passed in mandrel 3 gaps; The upper surface of positioning disk 2 is perpendicular to the axial line of mandrel 3; Pressing plate 4 is actively set on the mandrel 3, and mandrel 3 has smooth section 3 ', is with external splines tapered sleeve 5 on the smooth section 3 ' of mandrel; The interior circular hole of external splines tapered sleeve 5 and the smooth section matched in clearance of mandrel 3, interference fit between the internal spline of the male cone (strobilus masculinus) of external splines tapered sleeve 5 and inside spline wheel gear 6.The middle part of pressing plate 4 has stepped hole; Mandrel 3 activities are through in the aperture 41 of stepped hole; The upper surface of external splines tapered sleeve 5 is arranged in the macropore 42 of said stepped hole; And there is clearance distance between the upper surface of external splines tapered sleeve 5 and the hole of the said stepped hole shoulder 43, thereby produces interference between the upper surface that prevents external splines tapered sleeve 5 and the stepped hole hole shoulder 43.The end of mandrel 3 is provided with and is used for pressing plate 4 is carried out spacing nut 7.
The operation principle of the utility model is such: through bolt base 1 is connected with platen, after lathe debugging, calibration are qualified, external splines tapered sleeve 5 is packed in the internal spline of inside spline wheel gear 6; In this loading procedure; Do not compress between external splines tapered sleeve 5 and the inside spline wheel gear 6, external splines tapered sleeve 5 and inside spline wheel gear 6 integral body are penetrated on the mandrel 3, the lower surface of inside spline wheel gear 6 is supported on the upper surface of positioning disk 2; Thereby guarantee that inside spline wheel gear 6 is perpendicular with the axial line of mandrel 3; Again external splines tapered sleeve 5 is compressed, reach and reduce the gap and guarantee the correct dual purpose of clamping position, last clamping platen 5; And the nut 7 of screwing, can carry out gear hobbing.
