Abstract
The utility model relates to a processing contains the frock of the gear of internal spline, which comprises a column, the stand includes two sections cylinders, and the centre of two sections cylinders is equipped with one section crescent toper section of diameter from the overhead under, the cover is equipped with the inner ring cover in the toper section, the upper portion of the surface that the inner ring was sheathe in and the breach that the lower part was equipped with a plurality of symmetrical arrangement respectively, the outside cover of inner ring cover be equipped with with the internal spline matched with spline housing of gear, the less one end of toper section diameter is equipped with and is used for fastening the gland nut who sheathes in the inner ring with the gear. The utility model discloses an on locating the spline housing with the geared sleeve, then under gland nut's effect, with the gear fastening, simultaneously because the inner ring is sheathe in and is equipped with the breach, and under the effect of pressure, the inner ring cover can be expanded flexiblely, consequently can be used for processing the gear of different internal diameters size, the utility model discloses simple structure, convenient operation has improved workman's work efficiency greatly moreover.
Description
Technical field
The utility model belongs to gear machining technology field, is specifically related to a kind of frock for processing the gear containing internal spline.
Background technology
Gear a kind of well wheel rim has tooth can engage the mechanical organ transmitting motion and power continuously, and the application of gear in transmission has occurred very early.Some gear internal contain internal spline, usually the external tooth of this kind of gear needs with the internal spline of gear internal for benchmark is processed, therefore in the processing preparation process of gear, when processing external tooth, need gear to fix, and then external tooth is processed, but the frock being used for fixing gear is at present all comparatively complicated and loaded down with trivial details, be unfavorable for the operation of workman, operating efficiency is lower.
Utility model content
In order to solve the problem, the utility model provides a kind of frock for processing the gear containing internal spline, and when gear is fixed by needs, during the external tooth of machining gears, use the utility model to be fixed gear, it is simple to operation.
The frock of the gear of a kind of processing containing internal spline, comprise column, described column comprises two sections of cylinders, two sections of cylindrical centres are provided with one section of conical section put lower diameter from above and increase gradually, the upper and lower of the outer surface on described inner ring sleeve is respectively equipped with multiple breach be arranged symmetrically with, the outer cover of described inner ring sleeve is provided with the spline housing matched with the internal spline of described gear, and the less one end of described conical section diameter is provided with the clamp nut for being anchored on by gear on inner ring sleeve.
When needing the external tooth of machining gears, be located at by geared sleeve on spline housing, the internal spline of spline housing and gear cooperatively interacts, then clamp nut is tightened, under the effect of the pressure, thus gear is anchored on spline housing further, the processing of external tooth can be carried out gear.After completion of processing, unscrew clamp nut, take off gear.Simultaneously because inner ring sleeve of the present utility model is provided with breach, when clamp nut is tightened, under the effect of the pressure, inner ring sleeve can be expanded laterally, dilatation, therefore the gear of the utility model processing different inner diameters size.
As preferably, described inner ring sleeve upper and lower is respectively equipped with two breach be arranged symmetrically with.
As preferably, the outer surface of described spline housing is provided with the keyway matched with the internal spline of described gear.
Compared with prior art, the beneficial effects of the utility model are embodied in:
The utility model is by being located on spline housing by geared sleeve, then under the effect of clamp nut, gear is fastening, simultaneously because inner ring sleeve is provided with breach, under the effect of the pressure, inner ring sleeve can be expanded flexible, therefore can be used for processing the gear of different inner diameters size, the utility model structure is simple, and easy to operate, substantially increases work task efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model inner ring sleeve.
Detailed description of the invention
As shown in Figure 1, the utility model comprises column 1, column 1 comprises two sections of cylinders 11 and 12, the centre of two sections of cylinders 11 and 12 is provided with one section of conical section 13 put lower diameter from above and increase gradually, conical section 13 is arranged with inner ring sleeve 2, the upper and lower of the outer surface on inner ring sleeve 2 is respectively equipped with multiple breach 21 be arranged symmetrically with, under normal circumstances, inner ring sleeve 2 upper and lower is respectively equipped with two breach be arranged symmetrically with 21, see Fig. 2, the outer cover of inner ring sleeve 2 is provided with the spline housing 3 matched with the internal spline of gear, the outer surface of spline housing 3 is provided with the keyway 31 matched with the internal spline of gear.The less one end of conical section 13 diameter is provided with the clamp nut 4 for being anchored on by gear on inner ring sleeve 2.
Principle of the present utility model is:
When needing the external tooth of machining gears, be located at by geared sleeve on spline housing 3, spline housing 3 cooperatively interacts with the internal spline of gear, then clamp nut 4 is tightened, under the effect of the pressure, thus gear is anchored on further on spline housing 3, the processing of external tooth can be carried out gear.After completion of processing, unscrew clamp nut, take off gear.Simultaneously because inner ring sleeve 2 of the present utility model is provided with breach 21, when clamp nut is tightened, under the effect of the pressure, inner ring sleeve 21 can be expanded laterally, dilatation, therefore the gear of the utility model processing different inner diameters size.
Claims (3)
1. the frock of the gear of a processing containing internal spline, it is characterized in that, comprise column, described column comprises two sections of cylinders, two sections of cylindrical centres are provided with one section of conical section put lower diameter from above and increase gradually, described conical section is arranged with inner ring sleeve, the upper and lower of the outer surface on described inner ring sleeve is respectively equipped with multiple breach be arranged symmetrically with, the outer cover of described inner ring sleeve is provided with the spline housing matched with the internal spline of described gear, and the less one end of described conical section diameter is provided with the clamp nut for being anchored on by gear on inner ring sleeve.
2. the frock of the gear of processing as claimed in claim 1 containing internal spline, it is characterized in that, described inner ring sleeve upper and lower is respectively equipped with two breach be arranged symmetrically with.
