Abstract
The invention discloses a secondary broaching cutting tool for a big diameter of an inner ring gear of a synchronizer. The secondary broaching cutting tool comprises a front guider, a back guider and a cutter body, wherein splines are distributed on the outer peripheral surface of the front guider which is close to the cutter body and large-diameter spline teeth are distributed on the outer peripheral surface of the cutter body. According to the technical scheme, in the process of processing the inner ring gear of the synchronizer, a primary broaching tool is used for broaching the inner teeth and 0.1-0.15 margin is leaved, an outer circle is finely turned and an inner toothed back taper is extruded, and then the secondary broaching cutting tool provided by the invention is used for finely broaching the inner teeth, and lastly the inner teeth are chamfered, wherein the burrs, bosses, back tapers, and the like, which are leaved on the large diameters of the inner teeth after the primary broaching is finished are removed in the process of finely broaching the inner teeth. The precision of the inner ring gear of the synchronizer is promoted. The splines on the front guider of the secondary broaching cutting tool are engaged with the inner teeth of the ring gear after being primarily broached.
Description
Technical field
The present invention relates to a kind of process tool of automobile synchronizer ring gear, particularly a kind of cutter that the synchronized ring gear is carried out the big footpath processing of broaching for the second time.
Background technology
At present, when processing automobile synchronized ring gear, internal tooth all is once to broach by broaching cutters to form, that an existing broaching cutters comprises is leading, after lead and cutter hub, on cutter hub, establish big footpath spline tooth.Its processing technology is: draw the gear ring internal tooth, then the finish turning cylindrical, squeeze internal tooth back taper etc., obtain the synchronized ring gear at last the internal tooth chamfering.Though this technology is simple to operate, the defective that exists is: once broaching with broaching cutters forms, and easily stays burr, boss, back taper etc. on internal tooth, influences the precision of synchronized.Owing to exist above-mentioned defective, someone to propose to carry out the internal tooth machining second time, the cutter structure of internal tooth machining need solve the defective that processing for the first time stays for the second time, and this project becomes the problem that the sector is pursued.
Summary of the invention
Technical problem to be solved by this invention is to provide the big footpath of the synchronized ring gear secondary broaching process tool in the big footpath of the high synchronized ring gear of a kind of machining accuracy.
Technical scheme of the present invention is as follows: the big footpath of a kind of synchronized ring gear secondary broaching process tool, comprise leading, after lead and cutter hub, be distributed with spline near the leading external peripheral surface of cutter hub, the external peripheral surface of described cutter hub is distributed with big footpath spline tooth.
Adopt technique scheme, when processing synchronized ring gear, at first draw internal tooth with a broaching cutters, this moment made allowance 0.1-0.15, and then finish turning cylindrical, crowded internal tooth back taper etc., and then with secondary broaching cutters finish draw internal tooth of the present invention, in the operation of finish draw internal tooth, can remove one and draw burr on the internal tooth that the back produces, boss, back taper etc.Improve the precision of synchronized ring gear.Spline on two broaching tool tools are leading plays the effect that tooth is led with the internal tooth engagement of the gear ring after once broaching.
In technique scheme, for the ease of fixing, the secondary broaching tool is installed, described leading and after the end of leading be equipped with the card handle.
Beneficial effect: the present invention is reasonable in design, simple in structure, implement easily, and is easy to use and precision is high.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the AA enlarged drawing among Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As illustrated in fig. 1 and 2, the big footpath of synchronized ring gear secondary of the present invention broaching process tool by leading 1, after lead 2, spline 3, cutter hub 4, big footpath spline tooth 5 and card handle 6 form, leading 1 external peripheral surface near cutter hub is distributed with spline 3, this spline 3 and the internal tooth engagement of once drawing gear ring behind the internal tooth, the external peripheral surface of described cutter hub 4 is distributed with the big footpath of multi-turn spline tooth 5, and the big footpath of described spline 3 is less than the big footpath of big footpath spline tooth 5.Described leading 1 and after lead 2 end and be equipped with card handle 6.
Adopt technique scheme, can carry out finish draw to the internal tooth of synchronized ring gear, when processing synchronized ring gear, at first draw internal tooth with a broaching cutters, this moment made allowance 0.1-0.15, and then finish turning cylindrical, squeeze internal tooth back taper etc., use secondary broaching cutters finish draw internal tooth of the present invention at last, during the secondary broaching, the ring gear of the synchronized after once broaching is fixed, mobile cutter, leading 1 spline 3 of cutter at first with broaching once after the internal tooth engagement of ring gear of synchronized, play the effect to the tooth guiding, usefulness is provided with the big footpath of the cutter hub 4 finish draw internal tooths of big footpath spline tooth 5 again, can remove a burr that draws on the back big footpath of internal tooth that produces in the operation of finish draw internal tooth, boss, back taper etc.Improve the precision of synchronized ring gear.
Claims (2)
1. the big footpath of synchronized ring gear secondary broaching process tool, comprise leading (1), after lead (2) and cutter hub (4), it is characterized in that: be distributed with spline (3) at the external peripheral surface near leading (1) of cutter hub (4), the external peripheral surface of described cutter hub (4) is distributed with big footpath spline tooth (5).
