Abstract
The utility model provides a shaft gear bobbing tool which comprises a machine tool body, a conical locating seat with a step hole inside, a lower pushing tip mechanism and an upper pushing tip. The conical locating seat with the step hole inside is fixedly connected to the machine tool body, the lower pushing tip mechanism is arranged in the step hole in the conical locating seat with the step hole inside, the upper pushing tip and the lower pushing tip mechanism are coaxially arranged, and the conical face tip end of the upper pushing pin and the conical face tip end of the lower pushing tip mechanism are opposite. The shaft gear hobbing tool has the advantages that the method that a traditional clamping hoop is used for clamping a workpiece to drive the workpiece to rotate is changed to the method that end face teeth are used for driving the workpiece to rotate, a bar does not need to be reserved, cost is saved, machining processes are reduced, and gear hobbing precision can also be guaranteed due to the fact that long bars are not used.
Description
Technical field
The utility model is created the frock clamp field that belongs to gear hobbing processing, especially relates to a kind of gear hobbing tooling of shaft gear.
Background technology
Be by a blank bar (two～tri-planetary length) at existing hobbing method, after gear hobbing processing, cut off again operation.The weak point of the method is, need to reserve one section bar and carry out clamping work pieces, causes the waste of material; Because postorder also will cut off processing, also brought increase to processing cost; Bar is oversize simultaneously, and the gear hobbing precision is difficult for guaranteeing.
Summary of the invention
The utility model is created the gear hobbing tooling that the problem that will solve is to provide a kind of shaft gear.
For solving the problems of the technologies described above, the utility model is created the technical scheme adopted and is:
A kind of gear hobbing tooling of shaft gear, comprise: machine body, in establish the conical positioning seat of shoulder hole, lower tip mechanism, upper top, the conical positioning seat of establishing shoulder hole in described is fixed on described machine body, described lower tip mechanism is arranged in described in shoulder hole in the conical positioning seat of establishing shoulder hole, described top and described lower tip mechanism concentric is equipped with, and the conical surface is relatively most advanced and sophisticated.
Further, also comprise butterfly spring, described butterfly spring is arranged between the upper surface of the lower surface of described lower tip mechanism and machine body.
Further, described lower tip mechanism comprises the first step portion, first staged position limiting structure, the second step portion, the 3rd step portion, lower top, described the second step portion, the 3rd step portion and described in establish the shoulder hole corresponding part matched in clearance in the conical positioning seat of shoulder hole, the upper surface of described the first step portion with described in establish the conical positioning seat of shoulder hole the first shoulder hole upper surface contact, the lower surface of described the first step portion contacts with the upper surface of described butterfly spring.
Further, establish in described on the upper surface of conical positioning seat of shoulder hole several end-tooths are set.
Further, described end-tooth quantity be 6 with on 60 ° of upper surfaces that are distributed in described the conical positioning seat of establishing shoulder hole.
Further, described end-tooth cross section is conical, point upward.
The utility model is created the advantage and the good effect that have: drive the workpiece rotation by traditional clip clamping workpiece and change into the rotation of end-tooth drive workpiece, no longer need to reserve one section bar, provide cost savings, reduced manufacturing procedure, owing to not adopting long bar, the gear hobbing precision also can guarantee.

Fig. 2 is lower tip mechanism front view;
Fig. 3 is the upper surface Local map of lower tip mechanism.
In figure:
The 1-machine body; The 2-butterfly spring; Establish the conical positioning seat of shoulder hole in 3-; Tip mechanism under 4-; The 5-workpiece; 6-is upper top; 41-the first step portion; First staged position limiting structure of 42-; 43-the second step portion; 45-the 3rd step portion; Top under 46-.
The specific embodiment
A kind of gear hobbing tooling of shaft gear comprises as shown in Figure 1, 2, 3: machine body 1, in establish conical positioning seat 3, the lower tip mechanism 4, upper top 6 of shoulder hole, the conical positioning seat 3 of establishing shoulder hole in described is fixed on described machine body 1, described lower tip mechanism 4 is arranged in described in shoulder hole in the conical positioning seat 3 of establishing shoulder hole, described top 6 are equipped with described lower tip mechanism 4 concentrics, and the conical surface is relatively most advanced and sophisticated.Also comprise butterfly spring 2, described butterfly spring 2 is arranged between the upper surface of the lower surface of described lower tip mechanism 4 and machine body 1.Described lower tip mechanism 4 comprises the first step portion 41, first staged position limiting structure 42, the second step portion 43, the 3rd step portion 45, lower top 46, described the second step portion 43, the 3rd step portion 45 with described in establish the shoulder hole corresponding part matched in clearance in the conical positioning seat 3 of shoulder hole, the upper surface of described the first step portion 41 with described in establish the conical positioning seat 3 of shoulder hole the first shoulder hole upper surface contact, the lower surface of described the first step portion 41 contacts with the upper surface of described butterfly spring 2.Establish in described on the upper surface of conical positioning seat 3 of shoulder hole several end-tooths are set.Described end-tooth quantity be 6 with on 60 ° of upper surfaces that are distributed in described the conical positioning seat 3 of establishing shoulder hole.Described end-tooth cross section is conical, point upward.
When this utility model is specifically implemented, by lower top 46 of the center hole of workpiece 5 upper and lower end faces aligning upper top 6 and lower tip mechanism 4.Open and compress, upper top 6 move down workpiece pressing 5, and after the effect of being under pressure, lower top 46 in the vertical directions have 1mm-2mm to move down.End-tooth tip on conical positioning seat 3 is pressed in workpiece 5 lower surfaces, guarantees the frictional force reinforcement of frock and workpiece in the middle of hobbing process.After the gear hobbing operation starts, frock starts rotation with boss rod and carries out gear hobbing processing.End-tooth has guaranteed that the position of workpiece and frock in the rotary course without relative variation, improves machining accuracy.After the gear hobbing operation completes, move on upper top 6, butterfly spring 2 makes lower top 46 to recover initial positions.
The above embodiment that the utility model is created has been described in detail, but the preferred embodiment that described content is only created for the utility model can not be considered to the practical range of creating for limiting the utility model.All equalization variations of doing according to the utility model creation application range and improvement etc., within all should still belonging to the patent covering scope of the utility model creation.
