Abstract
The invention discloses a kind of end-tooth plane multikey broaching tool, comprise the leading and broaching tool teeth portion of broaching tool shank, broaching tool, broaching tool shank is provided with pin hole or draw-in groove, and the upper surface of broaching tool tooth is with nine plush coppers or nine grooves.Broaching tool of the present invention has the advantages such as high accuracy, high efficiency, high reliability, is specially adapted to processing belt end-tooth bead and flange york.
Description
Technical field
The present invention relates to a kind of broaching tool, especially a kind of end-tooth plane multikey broaching tool for processing belt end-tooth bead and flange york.
Background technology
At automotive field, driving-shaft assembly is very important parts, is transmitted the output torque of engine by the connection of power transmission shaft two ends bead and flange york.In the past, the cooperation between bead and flange york is located by seam and connected by multiple bolted, although structure is simple, but assembling difficulty, during use, moment loss is comparatively large, easily produces power transmission shaft failure conditions, and especially heavy truck field is larger by torque requirement to drive bearing.For this phenomenon, develop a kind of power transmission shaft bead and end face of flange yoke tooth draw bail in the world, and define international standard, international standard number is ISO12667.End-tooth draw bail utilizes nine of flange york end face spline tooths to coordinate with nine end face splines of bead, is connected by four bolted.Like this, bead and flange york assembling easily, connect reliable, and the moment loss of output is little, and bearing load is large, can meet the demand of heavy truck to large driving torque completely.At present, domestic Ge great Chong Ka power transmission shaft factory all refer to ISO12667 end-tooth and connects standard, and the Chong Ka power transmission shaft factory that output is large has selected Broaching Technology to process the end-tooth of bead and flange york all, and existing horizontal wire pulling method, also has vertical wire pulling method.But easily occur in actual production that broaching unstable product quality, the broaching tool quick abrasion life-span is short, produce required broaching tool high in cost of production problem, therefore end-tooth wire pulling method has become to attach most importance to the maximum bottleneck that card power transmission shaft is produced.
Summary of the invention
Technical problem to be solved by this invention is the end-tooth plane multikey broaching tool proposing a kind of high accuracy for processing belt end-tooth bead and flange york, high efficiency, high reliability.
For solving the problems of the technologies described above, end-tooth plane multikey broaching tool of the present invention comprises the leading and broaching tool teeth portion of broaching tool shank, broaching tool, and described broaching tool shank is provided with pin hole or draw-in groove, and the upper surface of described broaching tool tooth is with nine plush coppers or nine grooves.
Above-mentioned end-tooth plane multikey broaching tool, described broaching tool adopts overall structure, and the leading and broaching tool teeth portion of described broaching tool shank, broaching tool forms one.
End-tooth plane multikey broaching tool of the present invention comprises broach block one, broach block two, broaching tool box and block, and the leading portion of described broach block one is leading with broaching tool, and the back segment of described broach block one and described broach block two are respectively equipped with broaching tool tooth; Described broach block one and broach block two are fixedly connected on described broaching tool box respectively, described block is fixedly connected on one end of described broaching tool box, the rear end face of described broach block two is close to described block, the rear end face of described broach block one is close to the front end face of described broach block two, and the upper surface of described broaching tool tooth is with nine plush coppers or nine grooves.
Above-mentioned end-tooth plane multikey broaching tool, described broaching tool tooth adopts round cut structural design, one group of tooth is formed by two cutting teeths, rise per tooth is had between group and group, often to organize in tooth second cutting teeth, 0 ~ 0.01mm lower than first cutting teeth, often organize first large chamfering of cutting teeth two side grinding in tooth, large chamfering width accounts for 1/3 of the face width of tooth, large chamfering band relief angle 2 ~ 3 °.
The present invention is owing to have employed above-mentioned technical pattern, and it has the advantage of its uniqueness: 1, the large chamfering of round cut cutter tooth is with relief angle, and between main cutting edge and front cutting edge, angle is also very large, good heat dissipation, and wearing and tearing are slow, and tool life is high, good reliability; 2, because cutting width narrows, when identical tooth rises, reduce cutting force, during use, broaching is more steady.Meanwhile, because cutting width narrows, greatly reduce chip to the friction of surface of the work, improve the surface quality of product to be processed; 3, closely, in normal chip space, chip removal is better for broaching tool volume bits.End-tooth plane multikey broaching tool of the present invention can be adapted to different broaching machines.
