The broach with the end face tooth and the multi-spline flat comprises a broach handle, a broach guide portion and broach teeth, wherein the broach handle is provided with a bolt hole or a clamping slot, and the upper end face of the broach teeth is provided with nine protrusions or nine grooves. The broach has the advantages of high precision, high efficiency, high reliability and the like and is particularly suitable for processing a flange with end face tooth and a flange yoke.
Description
Technical field
The utility model relates to a kind of broaching tool, especially a kind of end-tooth for processing belt end-tooth bead and flange york plane multikey broaching tool.
Background technology
At automotive field, driving-shaft assembly is very important parts, transmits 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 was locate and connected by a plurality of bolted by seam, although simple in structure, but assembling difficulty, during use, moment loss is larger, easily produces the power transmission shaft failure conditions, and especially to drive bearing, required by moment larger in the heavy truck field.For this phenomenon, to develop in the world a kind of power transmission shaft bead and end face of flange yoke tooth draw bail, and formed international standard, international standard number is ISO12667.The end-tooth draw bail utilizes nine end face spline tooths of flange york to coordinate with nine end face splines of bead, by four bolted, is connected.Like this, bead and flange york assembling easily, connect reliably, and the loss of the moment of output is little, and bearing load is large, can meet the demand of heavy truck to large driving torque fully.At present, domestic each large heavy Ka Chuandongzhouchang has all quoted the ISO12667 end-tooth and has connected standard, and the heavy Ka Chuandongzhouchang that output is large has all selected the end-tooth of Broaching Technology processing bead and flange york, and existing horizontal broaching processing, also have vertical broaching processing.But easily occur in actual production that broaching unstable product quality, broaching tool quick abrasion life-span are short, produce required broaching tool high in cost of production problem, so end-tooth broaching processing become the to attach most importance to maximum bottleneck of card power transmission shaft production.
Summary of the invention
Technical problem to be solved in the utility model is to propose the end-tooth plane multikey broaching tool of 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, the utility model end-tooth plane multikey broaching tool comprises the broaching tool shank, broaching tool is leading and broaching tool tooth section, 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 described broaching tool shank, broaching tool is leading and broaching tool tooth section forms one.
The utility model end-tooth plane multikey broaching tool 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, on the back segment of described broach block one and described broach block two, is respectively equipped with the broaching tool tooth; Described broach block one and broach block two are fixedly connected on respectively on described broaching tool box, described block is fixedly connected on an 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 the round cut structural design, form one group of tooth by two cutting teeths, between group and group, rise per tooth is arranged, in every group of tooth, second cutting teeth is than the low 0 ~ 0.01mm of first cutting teeth, the large chamfering of first cutting teeth two side grinding in every group of tooth, large chamfering width accounts for 1/3 of the face width of tooth, 2 ~ 3 ° of large chamfering band relief angles.
The utility model is owing to having adopted above-mentioned technical pattern, and it has advantages of that it is unique: 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 down, when identical tooth rises, reduced cutting force, during use, broaching is more steady.Simultaneously, because cutting width narrows down, greatly reduce the friction of smear metal to surface of the work, improved the surface quality of product to be processed; 3, closely, in normal chip space, chip removal is better for broaching tool volume bits.The utility model end-tooth plane multikey broaching tool can be adapted to different broaching machines.
