Abstract
The invention provides a gear shaving tool which comprises a mandrel, a spline expansion sleeve and a nut. The left side of the spline expansion sleeve is internally in a cone shape, a first protrusion is formed at the end of the right side of the spline expansion sleeve, the inner surface of a protruded structure is matched with one section of the mandrel, the end face of the right side of the protruded structure is a pressing face matched with the nut, the lower end of the first protrusion is provided with an annular hole, a ring shaft capable of being matched with the annular hole is formed by extending at the left end of the nut, and a second protrusion capable of being matched with the first protrusion is formed at the left end of the ring shaft. According to the gear shaving tool, a contact area between the nut and the mandrel is increased, the spline expansion sleeve is installed accurately, an inner hole of the spline expansion sleeve is positioned well, the coaxiality of a center line of the spline expansion sleeve and a center line of the tool is reliably guaranteed, the problem that jumping inconsistency occurs when the spline expansion sleeve is reinstalled every time, so that workpieces are flattened is solved, and the gear shaving tool is simple to operate and convenient to use.
Description
Technical field
The invention belongs to gear shaving technology equipment field, specifically, relate in particular to a kind of tooth gear shaving technology equipment.
Background technology
Dish tooth class part is a kind of important gear member, usually by gear shaving machine, carrys out fine finishining dish tooth class part (hereinafter to be referred as workpiece) at present.Before shaving, need first gear shaver clamping on gear shaving technology equipment, existing dish tooth gear shaving technology equipment generally has two kinds of structures: the first is mechanical expansion compact form structure, this frock makes the swelling of swelling part under the effect of mechanical force, thereby the endoporus to spline expansion sleeve positions, but there is irregular, the inhomogeneous defect of swelling during swelling in swelling part under the effect of mechanical force, so just cause the center line of workpiece and the axiality of frock center line poor, and then there is eccentric situation, finally affect the machining accuracy of gear.
The second is polished rod type structure, this class frock is also that the endoporus of spline expansion sleeve is positioned, but the gap between the endoporus of spline expansion sleeve and polished rod with little surplus, so also can cause the center line of spline expansion sleeve and the axiality of frock center line poor, and then occur eccentric situation finally also can affecting the machining accuracy of gear.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of can the high gear shaving technology equipment of positioning precision.
A kind of gear shaving technology equipment, comprise mandrel, spline expansion sleeve and nut, described spline expansion sleeve left side is inner is taper, right-hand end is formed with one first projection, the inner surface of described the first projection matches with on described mandrel one section, its right end face is the seal face coordinating with described nut, described the first projection lower end arranges an annular circular hole, described nut left end prolongation is formed with the annulus axle that can match with described annular circular hole, and described annulus axle left end is formed with second projection that can coordinate with the first projection.
The circle of preferred described nut left end face and described annulus axle inner surface is beated and is less than or equal to 0.01.
The circle of the right lateral surface of preferred described spline expansion sleeve outer surface and described the first projection is beated and is less than or equal to 0.01.
Between preferred described annulus axle and described mandrel, it is basic hole system matched in clearance.
The length of preferred described annulus axle is not more than 20mm.
Gear shaving technology equipment provided by the invention, increase the contact area between nut and mandrel, spline expansion sleeve is installed precisely, well the endoporus of spline expansion sleeve is positioned, guaranteed reliably the axiality of center line and this frock center line of spline expansion sleeve, thereby it is inconsistent while preventing from resetting spline expansion sleeve, to beat at every turn, causes workpiece to be pressed partially, simple to operate, easy to use.

Fig. 2 is the fastening rear overall structure schematic diagram of gear shaving technology equipment provided by the invention.
Fig. 3 is the structural representation of the nut of gear shaving technology equipment provided by the invention.
Fig. 4 is the structural representation of the spline expansion sleeve of gear shaving technology equipment provided by the invention.
The specific embodiment
By the gear shaving technology equipment shown in Fig. 1 to Fig. 4, comprise mandrel 1, spline expansion sleeve 2 and nut 3, described spline expansion sleeve 2 left sides are inner is taper, right-hand end is formed with one first projection 21, the inner surface of described the first projection matches with on described mandrel 1 one section, its right end face is the seal face coordinating with described nut 3, described the first projection 21 lower ends arrange an annular circular hole 4, described nut 3 left ends prolongations are formed with the annulus axle 5 that can match with described annular circular hole 4, and described annulus axle 5 left ends are formed with second projection 51 that can coordinate with the first projection 21.
The length of preferred described annulus axle 5 is not more than 20mm.
While using gear shaving technology equipment provided by the invention, the annulus axle 5 of nut 3 is put into the annular circular hole 4 of spline expansion sleeve 2, the first projection 21 and the second projection 51 are matched, and integral body is inserted in by mandrel 1 right-hand member.
Wherein for guaranteeing accurate work piece positioning, the circle of described nut 3 left end face and described annulus axle 5 inner surfaces is beated and is less than or equal to 0.01, the circle of the right lateral surface of described spline expansion sleeve 2 outer surfaces and described the first projection 21 is beated and is less than or equal to 0.01, and the roughness of the left end face of the surfaces externally and internally of spline expansion sleeve 2 and the first projection 21 and nut 3 is 0.8.
For preventing interference fit between expansion error that the reasons such as Yin Wendu cause or annulus axle 5 and mandrel 1, nut 3 is not tightened with annulus axle 5 cannot be moved axially, and uses basic hole system H7/h6 matched in clearance between described annulus axle 5 and described mandrel 1.
Utilize technical solutions according to the invention, or those skilled in the art being under the inspiration of technical solution of the present invention, designs similar technical scheme, and reaching above-mentioned technique effect, is all to fall into protection scope of the present invention.
