Abstract
The invention discloses an upper positioning device of a push broach for processing an inner gear ring. The upper positioning device comprises an upper pressing head connected with an upper pressing handle of the push broach, wherein an inner hole for accommodating the upper pressing handle is formed in the upper pressing head, two parallel square holes are formed in the upper pressing head, each square hole is perpendicularly intersected with the inner hole, and a circular groove which is in key connection with the square holes is formed in the upper pressing handle. According to the upper positioning device, a key connecting the upper pressing head and the upper pressing handle can perform drawing and inserting movement under the drive action of a drive device, so that the upper pressing head and the upper pressing handle are separately connected, and the inner gear ring can be conveniently taken down from a work bench.
Description
Technical field
The invention belongs to metal cutting technology field, be specifically related to a kind of upper positioner of push broach of processing ring gear.
Background technology
The ring gear that is arranged on heavy-duty car rear axle wheel reductor is a kind of driving member that bears heavy load, belongs to the key components and parts in car transmissions.The technical requirement of ring gear is high, and manufacture difficulty is large, must be processed and just can be reached designing requirement by precision cutting.The method of processing ring gear is more, and conventional processing technology is Bevel Slotting Technology, Broaching Technology and broaching technique.Bevel Slotting Technology is the lower one of production efficiency in metal cutting, and the ring gear of processing under normal circumstances a Φ 200mm left and right needs 60～70 minutes consuming time, and this production efficiency does not obviously meet requirements of mass production.Broaching Technology belongs to a kind of precision cutting technique of field of machining, and single-blade cutting output is very little, and this technique breaks the whole up into parts cutting output, obtains finished product through order layering form-cutting.The modulus of gear is directly proportional to tooth depth, and large modulus tooth cutting output is large, need to have the cutting edge of sufficient amount to share cutting output, and how cutting edge certainly will increase broaching tool axial dimension.For example, the ring gear that broaching Φ 200mm bore and modulus are 4mm, need the long broaching tool ability Cost Allocation cutting output in 3m left and right, and the broaching tool manufacture of 3m length is very difficult, in addition the diameter of axle of 3m length is than large, and the rigidity of broaching tool own is poor, intensity is also very low, the broaching tool of ultra-fine length at all can not be for the production of, so Broaching Technology should not be made the ring gear of heavy caliber, large modulus, is only applicable to broaching small dimension, close-toothed ring gear.
Broaching technique is that a kind of production efficiency is high, the gear part of ring gear forming technology of good processing accuracy, low cost of manufacture.When the push broach of broaching equipment comes downwards to its tooth and is positioned at the below of ring gear, the upper end of push broach need be thrown off with positioner on it, make ring gear be able to take off on workbench, be connected so should be detachable between the upper positioner of broaching equipment and push broach, need in upper positioner and push broach, do corresponding structural design.
Summary of the invention
The object of the invention is to provide a kind of upper positioner of push broach of processing ring gear, and by the improvement of structure, push broach is connected with upper positioner is detachable, facilitates ring gear to take off on workbench.
For achieving the above object, the technical solution used in the present invention is: a kind of upper positioner of push broach of processing ring gear, comprise the seaming chuck being connected with the upper pressing handle of push broach, on described seaming chuck, offer the endoporus of accommodating described upper pressing handle, on described seaming chuck, be also provided with two square holes that are parallel to each other, described in each, square hole and described endoporus intersect vertically, and described upper pressing handle is provided with the cannelure being connected with described square hole key.In said structure, the key that connects seaming chuck and upper pressing handle can be realized and pull and push motion under the driving effect of drive unit, makes the detachable connection of seaming chuck and upper pressing handle, facilitates ring gear to take off on workbench.
In technique scheme, the lower end one of described cannelure is processed with positioning cylinder, and this positioning cylinder is provided with the flat side in location, and wherein described in one, the below of square hole is provided with locating hole, between described locating hole and the flat side in location, is equipped with alignment pin.
In technique scheme, connect described square hole and be fixedly connected with the key of cannelure and the output shaft of drive unit.
Further technical scheme, described in two, the lower surface of square hole is in the same plane.
Preferably, described locating hole is circular hole.
Further technical scheme, described drive unit is oil cylinder.
Because technique scheme is used, the advantage that the present invention compared with prior art has is:
1. the key that connects seaming chuck and upper pressing handle in the present invention can be realized and pull and push motion under the driving effect of drive unit, makes the detachable connection of seaming chuck and upper pressing handle, facilitates ring gear to take off on workbench.
