Abstract
The invention discloses an involute spline broach which comprises a handle, a transition cone, guiding keys, a cutting tooth, a corrected tooth, and a supporting part. The involute spline broach is characterized in that the cutting tooth comprises a small inner diameter cutting tooth, a middle inner diameter cutting tooth, a large inner diameter cutting tooth and a tooth-shaped cutting tooth, and the tooth-shape cutting tooth has the functions of cutting and guiding allocation. The guiding key on the right side of the transition cone and the guiding key on the left side of the supporting part are provided with lengthened guiding teeth. The lengthened guiding keys on the left side of the broach is rightward provided with the small inner diameter cutting tooth, the guiding key, the middle inner diameter cutting tooth, the guiding key, the large inner diameter cutting tooth, the tooth-shape cutting tooth, the corrected tooth, the guiding key, and the supporting part successively. According to the invention, three involute spline broaches with different inner diameters can be manufactured at one step, the axiality requirement of three different diameters of a workpiece to be machined and the consistency of spline tooth chamferings can be effectively ensured.
Description
Technical field
The present invention relates to a kind of involute spline broach and broaching method thereof, belong to metal cutting tool class technical field.
Background technology
The involute spline broach of prior art, its structure comprise neck, transition awl, front pilot, cutting portion, calibration portion, rear pilot.Described front pilot is cylindrical, and the whole cutting teeths of described cutting portion are same internal diameter, and described rear pilot is cylindrical.This involute spline broach can only be processed the splined hole of same internal diameter.But, a lot of involute spline holes special, that need two above different inner diameters of processing are arranged, the involute spline broach of prior art can not meet the demands fully.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of involute spline broach, the involute spline hole of three different inner diameters of its not only disposable processing, and can effectively guarantee the axiality requirement of three different inner diameters of work piece and the uniformity of spline tooth chamfering.
For solving the problems of the technologies described above, the invention provides a kind of involute spline broach, it contains pelmatozoa, transition awl, feather key, cutting teeth, correction tooth, rest portion.Described cutting teeth comprises little internal diameter cutting teeth, middle internal diameter cutting teeth, large diameter cutting teeth and profile of tooth cutting teeth, and the existing shear action of described profile of tooth cutting teeth has the effect of guide-localization again.On the feather key on described transition awl right side and the feather key in rest portion left side, be provided with the guiding tooth of lengthening.The lengthening guiding teeth directional right side in described broaching tool left side is provided with little internal diameter cutting teeth, feather key, middle internal diameter cutting teeth, feather key, large diameter cutting teeth, profile of tooth cutting teeth successively, proofreaies and correct tooth, feather key, rest portion.
Described feather key is provided with four, with the profile of tooth and the external diameter location of first three feather key of left side, guarantees the involute spline hole axiality requirement of three different inner diameters of work piece and the coherence request of spline tooth chamfering.
When using the present invention that workpiece is cut,, cut the little internal diameter of splined hole successively with first feather key location in left side; With second feather key location to the right, left side, the middle internal diameter of cutting splined hole; With the 3rd feather key location to the right, left side, the large diameter of cutting splined hole; With profile of tooth cutting teeth oneself location, remaining surplus on the chamfering of cutting splined hole and the profile of tooth; Calibrated tooth calibrates and scrapes light to profile of tooth.
