Description
Technical field
The present invention relates to technical field of mechanical processing, more particularly to a kind of limit clamp that processing is blocked up for gear copper.
Background technology
In recent years, mechanized equipment manufacturing industry is fast-developing, and people have manufactured and designed various mechanized equipments, with convenient
Various activities, the mechanized equipments such as the production of people, life are made of the parts of each different shapes and sizes and function,
Gear is the important part in mechanized equipment manufacturing industry, is mainly used in actuating unit, and various gears are also widely used for
In aero-engine, in the gear oil seal of aero-engine, the structure of some gear parts is the interior of gear shaft part
Hole carries out oil seal, in the structure design of gear, it is desirable to the endoporus of gear shaft is carried out after pressing copper to block up, it is stifled close carrying out rolling
Envelope, it is too soft relative to the hardness of gear material since most of material of sealing is all red copper material, therefore block up and roll in pressure
In stifled process, copper blocks up spacing inaccurate, and copper, which blocks up, when rolling is stifled is easily damaged, so as to cause substantial amounts of quality problems.For gear
The pressure copper of endoporus blocks up the unstable situation of processing quality existing for sealing processing, therefore, it is necessary to improve the spacing side of clamping that copper blocks up
Formula, limit copper block up the displacement along gear axial direction, further improve processing precision of products and processing quality.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of limit clamp that processing is blocked up for gear copper.
The present invention provides a kind of limit clamp that processing is blocked up for gear copper, including expansion set, mandrel and supporting block, institute
The one end for stating expansion set is installed with supporting block, and the other end of the expansion set stretches out gear lateral surface, in being equipped with the expansion set
Through hole, one end of the mandrel is set in the periphery for enabling the expansion set in the middle through hole and bore is interference fitted company
Connect, the other end of the mandrel is overhang to the expansion set.
Flange platform is additionally provided with the periphery of the expansion set, the end face of gear is close in a flange platform at least side end face.
The end profile of the supporting block matches with the appearance profile that copper blocks up.
The middle through hole is bellmouth.
The mandrel periphery is taper.
One end that the mandrel is stretched out outside the expansion set is additionally provided with set delthyrium.
The central axis and the central axis upright of the mandrel of the set delthyrium.
The supporting block is fixedly welded on the end of the middle through hole.
The beneficial effects of the present invention are：
It is most in gear rolls stifled process using the limit clamp provided by the present invention that processing is blocked up for gear copper
The material hardness that pipe copper blocks up is smaller, and support and position-limiting action due to limit clamp, limit the axial displacement that copper blocks up generation, and
When copper blocks up both sides and is subject to processing impact force, avoid copper and block up both side surface and scratched, and due to copper block up material have it is preferable
Ductility, when copper block up be squeezed power deformation when, extruding force is blocked up by copper and is transferred in the mandrel of limit clamp, forces mandrel edge
Bore moves axially, with the gradual distending of expansion set, expansion set and copper block up further be connected with bore it is closer so that
The local gap being filled with bore, improves sealing effect, so that facilitating user carries out machining operations, improves
Machining accuracy and processing quality, particularly this limit clamp is easy for installation, simple operation, especially suitable for large batch of gear
In the stifled processing of rolling.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：1- expansion sets, 2- mandrels, 3- supporting blocks, 4- copper block up, 5- gears.
Embodiment
Technical scheme is described further below in conjunction with attached drawing, but required protection domain does not limit to
In described；
The present invention provides a kind of limit clamp that processing is blocked up for gear copper, as shown in Figure 1, including expansion set 1, mandrel 2
And supporting block 3, one end of expansion set 1 are installed with supporting block 3, the other end of expansion set 1 stretches out 5 lateral surface of gear, in expansion set 1
Equipped with middle through hole, one end of mandrel 2 is set in the periphery for enabling expansion set 1 in middle through hole and 5 endoporus of gear is interference fitted connection,
The other end of mandrel 2 is overhang to expansion set 1.
Technical solution using the present invention, in gear rolls stifled process, although the material hardness that copper blocks up is smaller, due to
The support of limit clamp and position-limiting action, limit the axial displacement that copper blocks up generation, and copper blocks up both sides when being subject to processing impact force,
Avoid copper and block up both side surface and scratched, and there is preferable ductility since copper blocks up material, become when copper blocks up the power that is squeezed
During shape, extruding force is blocked up by copper and is transferred in the mandrel of limit clamp, forces mandrel to be moved axially along bore, with expansion set by
Gradually distending, expansion set and copper block up further be connected with bore it is closer, so as to be filled between the part in bore
Gap, improves sealing effect, so that facilitating user carries out machining operations, improves machining accuracy and processing quality, special
It is not that this limit clamp is easy for installation, simple operation, is rolled in stifled processing especially suitable for large batch of gear.
Further, flange platform is additionally provided with the periphery of expansion set 1, gear 5 is close in a flange platform at least side end face
End face.In this way, when expansion set is subject to the squeezing action power for coming from cutting tool, due to the end face position-limiting action of flange platform,
Expansion set end face is forced more closely to be bonded with gear face, sealing effect is more preferable.
Further, the end profile of supporting block 3 blocks up 4 appearance profile with copper and matches.
Further, middle through hole is bellmouth.Further, 2 periphery of mandrel is taper.So when mandrel is come from
When the squeezing action power of cutting tool, according to the relativization principle of power, mandrel produces reaction force to other parts, so as to squeeze
Expansion set is pressed, forces expansion set to open, further supports bore.
Further, one end that mandrel 2 is stretched out outside expansion set 1 is additionally provided with set delthyrium.By covering delthyrium, user can be used rod-shaped
Class instrument center roller is installed, and adjusts suitable fit clearance, for example, when needing to be completely embedded, can be manually by operation
Rod set enters to cover in delthyrium, and rotating operation bar, makes central axis so that expansion set gradually opens, reduce expansion set and bore it
Between fit clearance, achieve the purpose that improve sealing effect.
Further, the central axis of delthyrium and the central axis upright of mandrel 2 are covered.So installation is being adjusted easy to user
It is more time saving and energy saving during fit clearance.
Further, supporting block 3 is fixedly welded on the end of middle through hole.So be conducive to strengthen the company of supporting block and expansion set
Intensity is connect, extends the service life of limit clamp.
