Abstract
The utility model discloses a kind of internal diameter centering spline broach, comprise head connection handle, transfer neck, roughing tooth blade, finishing tooth blade, finishing teeth blade and afterbody connection handle that coaxial linear successively connects, described finishing tooth blade and finishing teeth blade form by spline inner diameter tooth and spline external diameter tooth, spline inner diameter tooth and spline external diameter tooth staggered.The structure that the utility model internal diameter centering spline broach adopts spline inner diameter tooth and spline external diameter tooth to be interspersed in the arrangement of finishing tooth blade and finishing teeth blade; ensure that to broach in the inside and outside footpath of spline endoporus simultaneously; change the structure of traditional interval, spline endoporus inside and outside footpath broaching; ensure spline tooth inside and outside footpath axiality; meet the technological requirement of spline path centering, guarantee spline crudy.
Description
Technical field
The utility model relates to machining tool field, particularly relates to a kind of internal diameter centering spline broach.
Background technology
In the processing of auto parts splined hole, tradition processing mode is that the inside and outside footpath of spline shapes successively, due to the impact by thickness of workpiece and broaching tool weight, often cause processed splined hole inside and outside footpath disalignment, if postorder requires spline inner diameter centering and carries out other as benchmark to add man-hour, cause the skimble-scamble position error of benchmark, affect the crudy of whole part.
Therefore, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of internal diameter centering spline broach, that it changes the structure of traditional interval, spline endoporus inside and outside footpath broaching, meet the technological requirement that auto parts splined hole internal diameter is felt relieved, internal-and external diameter coaxiality deviation is little.
The technical solution of the utility model is as follows:
A kind of internal diameter centering spline broach, comprise head connection handle, transfer neck, roughing tooth blade, finishing tooth blade, finishing teeth blade and afterbody connection handle that coaxial linear successively connects, described finishing tooth blade and finishing teeth blade form by spline inner diameter tooth and spline external diameter tooth, spline inner diameter tooth and spline external diameter tooth staggered.
Preferably, the tooth pitch between described spline inner diameter tooth and adjacent spline external diameter tooth is 4.5mm, and the height of described spline inner diameter tooth is 1.2mm, and the height of described spline external diameter tooth is 2.5mm.
Preferably, described roughing tooth blade is only provided with spline inner diameter tooth, the tooth pitch between adjacent spline internal diameter tooth is 4.5mm.
Preferably, the profile of tooth of described spline inner diameter tooth and spline external diameter tooth and chamfering consistent.
Beneficial effect: the structure that the utility model internal diameter centering spline broach adopts spline inner diameter tooth and spline external diameter tooth to be interspersed in the arrangement of finishing tooth blade and finishing teeth blade; ensure that to broach in the inside and outside footpath of spline endoporus simultaneously; change the structure of traditional interval, spline endoporus inside and outside footpath broaching; ensure spline tooth inside and outside footpath axiality; meet the technological requirement of spline path centering, guarantee spline crudy.

Detailed description of the invention
The utility model provides a kind of internal diameter centering spline broach, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
By reference to the accompanying drawings, a kind of internal diameter centering spline broach, comprise head connection handle 1, transfer neck 2, roughing tooth blade 3, finishing tooth blade 4, finishing teeth blade 5 and afterbody connection handle 6, above each parts successively coaxial linear connect.Head connection handle 1 and afterbody connection handle 6 are the retained part of broaching tool, and for transmitting pulling force, wherein head connection handle 1 connects broaching machine.Transfer neck 2 is the coupling parts between head connection handle 1 and roughing tooth blade 3, is also the place of marking.Described finishing tooth blade 4 is made up of spline inner diameter tooth 401 and spline external diameter tooth 402, spline inner diameter tooth 401 and spline external diameter tooth 402 staggered.Described finishing teeth blade 5 is made up of spline inner diameter tooth 501 and spline external diameter tooth 502, spline inner diameter tooth 501 and spline external diameter tooth 502 staggered.
As a kind of preferred embodiment of the present utility model, the tooth pitch between described spline inner diameter tooth and adjacent spline external diameter tooth is 4.5mm, and the height of described spline inner diameter tooth is 1.2mm, and the height of described spline external diameter tooth is 2.5mm.Described roughing tooth blade 3 is only provided with spline inner diameter tooth, and the tooth pitch between adjacent spline internal diameter tooth is 4.5mm.And the profile of tooth of described spline inner diameter tooth and spline external diameter tooth and chamfering consistent.
The utility model is the specific purpose tool of the splined hole wire pulling method of auto parts requirement spline inner diameter centering, the design of finishing tooth and finishing teeth adopt side set to distribute, ensure that to broach in the inside and outside footpath of spline endoporus simultaneously, change the structure of traditional interval, spline endoporus inside and outside footpath broaching, meet the technological requirement that auto parts splined hole internal diameter is felt relieved, internal-and external diameter coaxiality deviation is little.
Internal diameter centering spline broach actual add man-hour from right to left movement carry out, once complete shaping part working position.
According to the different thickness of processed auto parts, different staggered tooth pitches also can be designed.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection domain that all should belong to the utility model claims.
