Description
Technical field
The utility model relates to the fixture of using in gear teeth processing, and specifically a kind of end face drives hobbing machine fixture, belongs to mechanical part processing technique field.
Background technology
In gear teeth process, the existing normal fixture adopting is mandrel type, utilizes the Internal hole positioning of workpiece gear, and mandrel is fixed on workbench.But the clamping workload of this fixture is large, workpiece gear need to pack into and taking-up on mandrel, and inconvenience operates.Meanwhile, the gap of the endoporus of mandrel and workpiece gear requires again stricter, otherwise affects gear hobbing precision and the uniformity of workpiece gear, so the gap that need to control well between endoporus and the mandrel of workpiece gear.But in the time that the gap between endoporus and the mandrel of workpiece gear is too small, packing into and taking out more difficultly again of workpiece gear, and easily pulls the bore area of workpiece gear, from and affect the precision of mandrel.Therefore, there is operation inconvenience in traditional mandrel type fixture, and workpiece gear precision uniformity is poor, and workpiece gear endoporus such as easily pulls at the problem.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of end face to drive hobbing machine fixture, and it is simple in structure, easy and simple to handle, quick, efficient, good reliability, can realize the quick and precisely centering of gear, meets the processing of gear high accuracy and mass production requirement.
The technical scheme providing according to the utility model: end face drives hobbing machine fixture, it is characterized in that: comprise base, adjusting nut, brute spring, jackscrew and floating centre, described base top is provided with circumferentially uniform end face ratchet, base center is provided with installing hole, in the base-mounted installing hole of described brute spring and floating centre, floating centre is withstood in brute spring upper end, and brute spring lower end is supported on adjusting nut, and adjusting nut is threaded in installing hole; Described jackscrew radially runs through base outer wall, and in the inner axial elongated slot embedding on floating centre periphery wall of jackscrew, jackscrew can prevent that floating centre from ejecting or dropping, and limits the rotation of floating centre.
As further improvement of the utility model, described floating centre bottom is provided with blind hole, and described brute spring is contained in blind hole.
compared with prior art, advantage is the utility model:
(1) the utility model utilizes floating centre and upper top cooperation to carry out positioning workpieces gear, and positioning precision is high, and machining accuracy is high, high conformity.
(2) the utility model adopts brute spring to drive floating centre, guarantees the centre bore of positioning workpieces gear reliably.
(3) the utility model utilizes the end face of end face ratchet incision workpiece gear to produce driving force man-hour adding, drive reliable, the clamping of workpiece gear with unload simple and efficient.
(4) the utility model utilizes adjusting nut to support brute spring, can conveniently adjust the amount of contraction of brute spring, with the reliable positioning workpieces gear of Reliable guarantee floating centre, ensures again that end face drives simultaneously strong reliable.
(5) the utility model is simple in structure, easy and simple to handle, quick, efficient, and good reliability can realize the quick and precisely centering of gear, meets the processing of gear high accuracy and mass production requirement.Advantage easy and simple to handle, efficiency is high, can adapt to the occasion of gear high accuracy processing and mass production requirement.
Brief description of the drawings

Fig. 2 is the structural representation of the end face ratchet of base top in Fig. 1.
Fig. 3 is the structure chart of adjusting nut in Fig. 1.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the end face in embodiment drives hobbing machine fixture to be mainly made up of parts such as base 1, adjusting nut 2, brute spring 3, jackscrew 4 and floating centres 5.
As Fig. 1, described base 1 top is provided with circumferentially uniform end face ratchet 1a, base 1 center is provided with installing hole, described brute spring 3 and floating centre 5 are contained in the installing hole on base 1, floating centre 5 is withstood in brute spring 3 upper ends, brute spring 3 lower ends are supported on adjusting nut 2, and adjusting nut 2 is threaded in installing hole; Described jackscrew 4 radially runs through base 1 outer wall, and in the inner axial elongated slot embedding on floating centre 5 periphery walls of jackscrew 4, jackscrew 4 can prevent that floating centre 5 from ejecting or dropping after adjusting nut 2 is loosening, and limits the rotation of floating centre 5.
As shown in Figure 1, described floating centre 5 bottoms are provided with blind hole, and described brute spring 3 is contained in blind hole, can make like this brute spring 3 in the time being subject to force compresses, keep stable, thereby make floating centre 5 keep stable, improve machining accuracy.
Operation principle of the present utility model is as follows:
The utility model need to upper top 6 be used in conjunction with, upper top 6 be fixed on lathe upper top 6 upper, upper top 6 can move up and down with upper top 6 under hydraulic action.
When concrete application, the utility model is arranged under top 6, base 1 is connected with platen, workpiece gear 7 is contained on floating centre 5, start on lathe the hydraulic pressure of top 6, upper top 6 move down, and withstand the top of workpiece gear 7, now, under the effect of brute spring 3, workpiece gear 7 is reliably located by two upper and lower top realizations.Continue in descending process upper top 6, brute spring 3 is subject to force compresses, the lower surface of workpiece gear 7 contacts with the end face ratchet 1a at base 1 top and further interlock incision gradually, until workpiece gear 7 directly contacts with base 1 top end face, the at this moment location work of workpiece gear 7 completes.The end face ratchet 1a at base 1 top cuts workpiece gear 7 end faces completely, and top 6 pressure in maintenance now can start processing.
After machining, start on lathe the hydraulic pressure of top 6, make top 6 to move upward, leave workpiece gear 7, under the effect of brute spring 3, the end face of workpiece gear 7 is separated from base 1 top end face and end face ratchet 1a, now can conveniently take out workpiece gear 7.
Above-mentioned course of action utilized the floating centre 5 and upper top 6 incompatible centering that completes workpiece gear 7 that matches before this, and then produced driving force man-hour with the end face of end face ratchet 1a incision workpiece gear 7 so that adding.
