For the deficiency that prior art exists, the purpose of this utility model is to provide the worm gear hobbing fixture that a kind of structure is simple, locate reliably, easily ensure machining accuracy and transmission accuracy.
For achieving the above object, the utility model provides following technical scheme: a kind of worm gear hobbing fixture, comprise worm gear, described worm gear lower end is socketed with retainer, described retainer is at least provided with three steel ball holes, a steel ball is set in each steel ball hole, described retainer side is provided with screw hole, support ring is socketed with outside described retainer, the endoporus internal face of support ring has been wholely set steel ball limiting section, described support ring alignment screw hole site offers adjusting hole, adjustment screw is provided with in this adjusting hole, adjustment screw head is threaded with screw hole, adjustment screw afterbody exposes adjusting hole and arranges, by promoting adjustment screw, retainer is rotated along the endoporus internal face of support ring, thus it is fixing to make steel ball clamp with worm gear outside wall surface under the effect of steel ball limiting section.
By adopting technique scheme, retainer vibrational power flow is reasonable, and steel ball plays the effect of bearing, by promoting adjustment screw, retainer is rotated along the endoporus internal face of support ring, thus steel ball is clamped with worm gear outside wall surface under the effect of steel ball limiting section, complete radial location.Structure is simple, location is reliable, easily ensure machining accuracy and transmission accuracy.
The utility model is set to further: the steel ball hole on described retainer is evenly arranged around the center of circle, and steel ball bore dia is all equal.By this setting, steel ball hole arranges rationally, locates more reliable.
The utility model is also set to further: the endoporus internal face of described support ring is evenly provided with three steel ball limiting sections, and three steel ball limiting sections mate with three steel ball holes.By this setting, supporting ring structure arranges more reasonable, and steel ball limiting section structure is simple, quantity arranges rationally, locates more reliable.
The utility model is also set to further: each steel ball limiting section is off-centre operation cambered surface, and each off-centre operation cambered surface radially size reduces gradually.By this setting, steel ball limiting section structure is simple, quantity arranges rationally, locates more reliable.
The utility model is also set to further: described worm gear deviates from maintenance frame end and is provided with cushion block, cushion block is outside equipped with clamp nut, be plugged with plug in the endoporus of described worm gear, cushion block and clamp nut all deviate from plug and keep frame end to be socketed, and are locked by clamp nut.By this setting, vibrational power flow is more reasonable, convenient fixing, connects reliable.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is reasonable, steel ball on retainer plays the effect of bearing, by promoting adjustment screw, retainer is rotated along the endoporus internal face of support ring, thus steel ball is clamped with worm gear outside wall surface under the effect of steel ball limiting section, complete radial location.Structure is simple, location is reliable, easily ensure machining accuracy and transmission accuracy.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the cross-sectional schematic of the utility model embodiment retainer;
Fig. 3 is the cross-sectional schematic of the utility model embodiment support ring.
Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 3, a kind of worm gear hobbing fixture disclosed in the utility model, comprise worm gear 1, described worm gear 1 lower end is socketed with retainer 2, described retainer 2 is at least provided with three steel ball holes 21, a steel ball 3 is set in each steel ball hole 21, described retainer 2 side is provided with screw hole 22, support ring 4 is socketed with outside described retainer 2, the endoporus internal face of support ring 4 has been wholely set steel ball limiting section 41, position, described support ring 4 alignment screw hole 22 offers adjusting hole 42, adjustment screw 5 is provided with in this adjusting hole 42, adjustment screw 5 head is threaded with screw hole 22, adjustment screw 5 afterbody exposes adjusting hole 42 and arranges, by promoting adjustment screw 5, retainer 2 is rotated along the endoporus internal face of support ring 4, thus it is fixing to make steel ball 3 clamp with worm gear 1 outside wall surface under steel ball limiting section 41 acts on, and until block completely, complete radial location.
For making the utility model structure more reasonable, as preferably, the steel ball hole 21 on retainer 2 described in the present embodiment is evenly arranged around the center of circle, and steel ball hole 21 diameter is all equal.The retainer 2 of the present embodiment is arranged altogether three steel ball holes 21.
The endoporus internal face of described support ring 4 is evenly provided with three steel ball limiting sections 41, and three steel ball limiting sections 41 mate with three steel ball holes 21, namely three steel ball limiting sections 41 are aimed at a steel ball hole 21 respectively and are arranged.Each steel ball limiting section 41 is off-centre operation cambered surface, and each off-centre operation cambered surface radially size reduces gradually.
Described worm gear 1 deviates from retainer 2 end and is provided with cushion block 6, cushion block 6 is outside equipped with clamp nut 7, plug 8 is plugged with in the endoporus of described worm gear 1, cushion block 6 and clamp nut 7 all deviate from retainer 2 end and are socketed with plug 8, and be locked by clamp nut 7, even if worm gear 1 and integrated tooling clamp completely.
