Abstract
The utility model discloses a double-orientation involute internal spline broach which comprises a front portion orientating part and a back portion orientating part. The front portion orientating part comprises a round hole guiding portion and a first spline portion which are connected in sequence, the back portion orientating part comprises a round hole broaching portion and a second spline portion which are connected in sequence, and the round hole guiding portion, the first spline portion, the round hole broaching portion and the second spline portion are sequentially, coaxially and linearly connected. The round hole guiding portion is used for achieving the inner hole guiding effect, and the first spline portion is used for achieving the effect of guiding hole diameter and tooth shapes of an internal spline. A part of deformation amount of the hole diameter of the internal spline is removed from the round hole broaching portion, and the second spline portion achieves the effect of guiding the tooth shapes of the internal spline. By utilizing the double-orientation involute internal spline broach with a double-orientation structure, processing of a part with a large internal spline hole diameter deformation amount caused by a tooth rolling process can be achieved, the processing accuracy of the part is ensured, and the part rejection rate in the production process is greatly reduced.
Description
Technical field
The utility model relates to a kind of two guiding involute inner spline broaching tool, can realize causing and the processing of the part that internal spline aperture deflection is big belonging to the machining tool field because rolling the tooth operation.
Background technology
Along with the machine components quality requirement is more and more higher, structure becomes increasingly complex, for the also more and more polynary change of requirement of the needed cutting tool of part processing, and require not only to be confined to the accuracy of manufacture aspect of cutter, the requirement of tool type and structure aspects is also more and more higher.
At present, the involute inner spline aperture is that the processing mode that utilizes the involute inner spline broaching tool to broach is realized, as shown in Figure 1, common involute inner spline broaching tool has only single guiding, formed by circular hole leader 01 and spline guides part 02 two parts, its shortcoming is to roll the tooth extruding and causes the internal spline aperture to diminish, and makes that hard extruding is caused in the targeting part of broaching tool and internal spline aperture in the process in secondary broaching internal spline aperture.So can make internal spline aperture and broaching tool relatively rotate difficulty, cause the spline guides part of broaching tool can't aim at the workpiece internal spline, lose its circumference guide effect, cause guiding tooth flank to push workpiece internal spline flank firmly, destroy the outward appearance of internal spline flank, caused workpiece to scrap.

Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is the structural representation of the two guiding of the utility model involute inner spline broaching tool.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 2, a kind of two guiding involute inner spline broaching tool, comprise anterior guiding and rear portion guiding, described anterior guiding comprises circular hole leader 1 and first splined section 2 that connects successively, described rear portion guiding comprises circular hole broaching part 3 and second splined section 4 that connects successively, and described circular hole leader 1, first splined section 2, circular hole broaching part 3, second splined section 4 are coaxial linear the connection successively.The effect of anterior guiding is to play the effect of internal spline aperture positioning and guiding for circular hole broaching part and second splined section 4 in the guiding of rear portion.
Described two guiding involute inner spline broaching tool, it is characterized in that: described circular hole leader 1 is used for realizing the effect of endoporus guiding, described first splined section 2 is used for realizing the guide effect of internal spline aperture and profile of tooth.
Described two guiding involute inner spline broaching tool, it is characterized in that: described circular hole broaching part 3 is provided with the blade cutting structure for the part deflection of removing the first splined section internal spline aperture, and described blade cutting structure is annular.Circular hole broaching part is for having the cutting tip of blade.
Described two guiding involute inner spline broaching tool, it is characterized in that: described second splined section 4 plays the guide effect of internal spline profile of tooth.
Described two guiding involute inner spline broaching tool is characterized in that: the internal spline profile of tooth and the chamfering that arrange on described first splined section 2 and second splined section 4 are consistent.
Described two guiding involute inner spline broaching tool is characterized in that: the external diameter of described circular hole leader 1 and circular hole broaching part 3 is the 85-90 millimeter.As preferred version, the external diameter of circular hole leader 1 and circular hole broaching part 3 is 87.15 millimeters in the present embodiment.
The course of work of the present utility model is as follows: the utility model has more the rear portion guiding with circular hole broaching part than common involute inner spline broaching tool.In process, at first the anterior guiding of contact contacts the rear portion guiding afterwards; Circular hole leader 1 is realized the effect of endoporus guiding, and first splined section 2 realizes the guide effect of internal spline aperture and profile of tooth, and circular hole broaching part 3 is removed the part deflection in internal spline aperture, and second splined section 4 realizes the effect of guiding internal spline profile of tooth.By the effect of front portion guiding, utilize the circle of circular hole broaching part 3 to draw tooth to broach to roll the distortion internal splined hole after the tooth operation, equal to have led again internal splined hole; The effect of second splined section 4 of rear portion guiding is exactly the normal internal spline profile of tooth that leads.Thus, utilize the involute inner spline broaching tool of dual-guiding structure, can realize causing the processing of the part that internal spline aperture deflection is big because rolling the tooth operation, guarantee the machining accuracy of part, greatly reduce the part scrappage in the production process.
