Description
Technical field
The present invention relates to technical field of mechanical processing more particularly to a kind of limit clamps for the stifled processing of gear copper.
Background technique
In recent years, mechanized equipment manufacturing industry is fast-developing, and people have manufactured and designed various mechanized equipments, with convenient
The various activities such as production, the life of people, mechanized equipment are made of the components 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 that the inner hole of gear shaft carry out pressure copper it is stifled after, carry out rolling block up it is close
Envelope, since most of the material of sealing is all red copper material, the hardness relative to gear material is too soft, therefore blocks up and roll in pressure
In stifled process, the stifled limit of copper is inaccurate, and copper is stifled when rolling is stifled is easily damaged, so as to cause a large amount of quality problems.For gear
The unstable situation of existing processing quality is processed in the stifled sealing of pressure copper of inner hole, therefore, it is necessary to improve the stifled clamping limit side of copper
Formula, the stifled displacement along gear axial direction of limit copper, further increases processing precision of products and processing quality.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of limit clamps for the stifled processing of gear copper.
The present invention provides a kind of limit clamp for the stifled processing of gear copper, including expansion set, mandrel and supporting block, institutes
The one end for stating expansion set is fixedly installed with supporting block, the other end of the expansion set stretches out gear lateral surface, is equipped in the expansion set
Through-hole, one end of the mandrel, which is set in the middle through-hole, enables the periphery of the expansion set to be interference fitted company with bore
It connects, the other end of the mandrel is stretched out to outside the expansion set.
Flange platform is additionally provided on the periphery of the expansion set, the end face of gear is tightly attached 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 foreign circle face is taper.
One end that the mandrel is stretched out outside the expansion set is additionally provided with set delthyrium.
The central axis of the set delthyrium and the central axis upright of the mandrel.
The supporting block is fixedly welded on the end of the middle through-hole.
The beneficial effects of the present invention are:
Using the limit clamp provided by the present invention for the stifled processing of gear copper, rolled in stifled process in gear, to the greatest extent
The stifled material hardness of pipe copper is smaller, support and position-limiting action due to limit clamp, limits the stifled axial displacement generated of copper, and
When the stifled two sides of copper are subject to processing impact force, avoid the stifled both side surface of copper and scratched, and have preferably since copper blocks up material
Ductility, when copper is stifled be squeezed power deformation when, extruding force is transferred in the mandrel of limit clamp by the way that copper is stifled, forces mandrel edge
Bore axial movement, with expansion set gradually distending, expansion set and copper it is stifled further connect with bore it is closer, thus
The local gap being filled in bore, improves sealing effect, so that facilitating user carries out machining operations, improves
Machining accuracy and processing quality, especially this limit clamp are easy for installation, and it is convenient to operate, especially suitable for large batch of gear
In the stifled processing of rolling.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1- expansion set, 2- mandrel, 3- supporting block, 4- copper is stifled, 5- gear.
Specific embodiment
Technical solution of the present invention is described further below in conjunction with attached drawing, but required protection scope does not limit to
In described；
The present invention provides a kind of limit clamps for the stifled processing of gear copper, as shown in Figure 1, including expansion set 1, mandrel 2
And supporting block 3, one end of expansion set 1 are fixedly 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, which is set in middle through-hole, enables the periphery of expansion set 1 to be interference fitted connection with 5 inner hole of gear,
The other end of mandrel 2 is stretched out to outside expansion set 1.
Using technical solution of the present invention, rolled in stifled process in gear, although the material hardness that copper blocks up is smaller, due to
The support of limit clamp and position-limiting action, limit the stifled axial displacement generated of copper, and when copper blocks up two sides and is subject to processing impact force,
It avoids the stifled both side surface of copper to be scratched, and since copper blocks up material with preferable ductility, becomes when copper blocks up the power that is squeezed
When shape, extruding force is transferred in the mandrel of limit clamp by the way that copper is stifled, and mandrel is forced to move axially along bore, with expansion set by
Gradually distending, expansion set and copper is stifled further connect with bore it is closer, 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, it is convenient to operate, and rolls in stifled processing especially suitable for large batch of gear.
Further, flange platform is additionally provided on the periphery of expansion set 1, gear 5 is tightly attached in a flange platform at least side end face
End face.In this way, when expansion set is by squeezing action power from cutting tool, due to the end face position-limiting action of flange platform,
Force expansion set end face with gear face is closer is bonded, sealing effect is more preferable.
Further, the end profile of supporting block 3 matches with the appearance profile of copper stifled 4.
Further, middle through-hole is bellmouth.Further, 2 periphery of mandrel is taper.In this way when mandrel is come from
When the squeezing action power of cutting tool, according to the relativization principle of power, mandrel generates reaction force to other parts, 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 tool center roller is installed, and adjusts suitable fit clearance, for example, when needing to be completely embedded, it can be manually by operation
Rod set enters to cover in delthyrium, rotates operating stick, makes central axis, so that expansion set be made gradually to open, 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.Installation is being adjusted in this way convenient for user
It is more time saving and energy saving when fit clearance.
Further, supporting block 3 is fixedly welded on the end of middle through-hole.Be conducive to enhance the company of supporting block and expansion set in this way
Intensity is connect, the service life of limit clamp is extended.
