Abstract
The utility model discloses a self-centering pipe plug, comprising a spindle and a holding body. The peripheral surface of the holding body is provided with a support holder, and the spindle has a conical middle portion and a thread front end face. The self-centering pipe plug increases production efficiency of pipe barrels and the like, increases machining precision of sleeve barrels and the like, and reduces technical requirements to operators in small and middle batch production, which is characterized by easy operation and low cost.
Description
Technical field:
The utility model relates to a kind of socket class part machinery fixture for processing, is exactly a kind of self-alignment pipe plug that is used for the processing of socket class part machinery specifically.
Background technique:
Some long tube tube kind parts need be processed two end flange cylindricals and end face, and need to guarantee the coaxality of two ends cylindrical and end face and directly jump requirement, because workpiece is longer, and clamping centering difficulty, the Geometrical Tolerance Principle of proposition in being difficult to guarantee to design.People just work hard in the frock design.The frock design is too complicated, makes difficulty, and processing cost is too high; Though structure is simple, machining accuracy does not reach designing requirement, so the processing tube tube kind part becomes a difficult problem in the machine-building.
In small lot batch manufacture, people cooperate the processing of center rest clamping centering with four jaw chuck usually, waste time and energy, to operator's technical requirements height at present.In production in enormous quantities, people often design specialized lathe process, and the design of special purpose machine tool and manufacturing investment are big, and the cycle is long, and efficient is low.At present general enterprise lots of production is not very big, and people's expectation has a kind of little investment, and the processing method of certain work efficiency is arranged again.Want to reach this purpose, just must design the frock of fairly simple practicality.
The model utility content:
The utility model purpose provides a kind of work efficiency that can improve socket class part, improves machining accuracy, reduces production costs and self-alignment pipe plug easy to use, is used for remedying the deficiency of prior art problem.
In order to achieve the above object, the technical solution of the utility model is as follows:
The self-alignment pipe plug comprises axle and fixture; Circumferential surface at fixture also is provided with supporting claw, and the axle middle part is set to cone, and this axle front end is set to thread surface.
At above-mentioned self-alignment pipe plug, wherein, above-mentioned supporting claw is provided with three, and is evenly distributed on the circumferential surface of fixture, and the cone surface of this supporting claw one end and axle is suitable; Mandrel can make supporting claw and fixture produce relative movement, under the effect of conical surface, makes supporting claw support enlarged diameter or dwindles.
At above-mentioned self-alignment pipe plug, wherein, there is center hole at above-mentioned axle two end part, for adding top the holding out against of tail stock in man-hour; The axle outer end is set to hexagonal shaped, can be suitable with spanner, and spanner loading and unloading easy to use.
At above-mentioned self-alignment pipe plug, wherein, also be provided with the spring that is enclosed within on the supporting claw in the above-mentioned fixture and overlapped the gland on the fixture of being stuck in of supporting claw, described spring one end overhead is on the big end shaft shoulder of supporting claw, its the other end overhead is on gland, and the elastic force by spring is in contact with one another the circular cone dignity at supporting claw and axle middle part.
At above-mentioned self-alignment pipe plug, wherein, above-mentioned fixture front end is provided with internal thread, and this internal thread and axle front end flank of thread are suitable, and mandrel can make axle and supporting claw produce relative movement.
When processing is used, earlier the utility model is put into the end of pipe, used the spanner mandrel, supporting claw outwards moves, and the stretching ips is clamped in the mouth of pipe self-alignment pipe plug, withstand with tail stock is top then, just can process flange hole, cylindrical and end face.After the use, mandrel round about again, in like manner, supporting claw moves inward, and can unclamp.
The beneficial effect that the utility model compared with prior art has is, in small batch production guiding principle, improved the work efficiency of socket class part, improved the machining accuracy of sleeve part, alleviated operator's labor intensity, reduced technical requirements to the operator, and easy to use, reduced cost of production.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the utility model self-alignment pipe plug.
Fig. 2 is the front schematic view of the utility model self-alignment pipe plug.
Fig. 3 is an an embodiment's of the present utility model schematic representation.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to figure 1, Fig. 2, Fig. 3, the self-alignment pipe plug comprises axle 1, fixture 2, spring 5, gland 4 and supporting claw 3 compositions.Fixture 2 of the present utility model is wrapped in the surface of axle 1, and be round pie, three conical surfaces with internal mandrel 1 evenly are installed on fixture 2 circumferential surfaces are connected the supporting claw 3 that touches, this supporting claw 3 is a slip surface 6 with 1 oblique contact position of axle, supporting claw 3 big end cross-sectional areas are greater than the sectional area of supporting claw 3 small ends, around supporting claw 3, be set with spring 5, supporting claw 3 is by the elastic force of the spring 5 on it, thereby the slip surface 6 of maintenance supporting claw 3 contacts with the conical surface of axle 1 constantly; The other end overhead of spring 5 is on gland 4, and gland 4 is fixed on the fixture 2, thereby whole spring 5 is closed in the fixture 2.Through the center of round pie fixture 2 are axles 1, be set to cone at axle 1 middle part, axle 1 front end surface is a flank of thread, this flank of thread matches with tapped hole on the fixture 2, mandrel 1 can make axle 1 and fixture 2 produce relative movement, under the effect of conical surface, makes supporting claw 3 support enlarged diameter or dwindles, there is center hole 7 at axle 1 two end part, for adding top the holding out against of tail stock in man-hour; Be processed into hexagonal shaped or square in axle 1 outer end, can match with the spanner that uses.
When processing is used, earlier the utility model is put into the end of pipe 9, with spanner mandrel 1, under the effect of axle 1 front threads pair, cause cone to move forward, thereby supporting claw 3 is outwards moved, stretching pipe 9 internal diameters, the utility model is clamped in the mouth of pipe, withstands the center hole 7 of axle 1 end then with tail stock top 8, but the just flange hole of processing accessories, cylindrical and end face.After the use, mandrel 1 round about, and the cone at axle 1 middle part moves backward, thereby supporting claw 3 is moved inward under the effect of spring 5, can allow anchor clamps and part unclamp.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
