Chuck, precision or life-span, stability cannot all ensure processing request.In addition the mode of production of automatic high-efficiency rate is more next
More universalness, to the use of collet also more and more extensively, the processing length change of caught workpiece is also more and more so that
It is difficult to be accurately positioned in the course of processing, it is impossible to ensure machining accuracy, cause percent defective to increase, as shown in Figure 1.
It would therefore be highly desirable to solve the above problems.
Utility model content
Utility model purpose：The purpose of this utility model is to provide parts to be processed during one kind effectively improves the course of processing and exists
The positioning precision of collet interior, ensures the high accuracy chuck with accurate interior positioning function of clamping workpiece stability.
Technical scheme：For realizing object above, a kind of high accuracy chuck with positioning function in accurate of this utility model,
The interior axle for positioning parts to be processed including collet body and inside collet body, wherein interior axle form one in chuck body
Prop up the axial force of parts to be processed.
Wherein, one end outer wall of the collet body has the conical surface, the collet body near the end of the conical surface from outside to inside successively
Including the first shoulder hole, the second shoulder hole and the 3rd screwed hole, wherein described first shoulder hole is for clamping parts to be processed
Clamping endoporus.
Preferably, the interior axle includes threaded portion and thin rod part, and wherein, the threaded portion screws in the 3rd screwed hole, carefully
Bar portion is stretched in the second shoulder hole.
Further, the end face of the threaded portion of the interior axle is provided with the convenient notch for screwing in interior axle.Achievable interior axle it is quick
Install.
Furthermore, the end face of the thin rod part of the interior axle offers chamfering.
Preferably, the collet body and interior axle are spring steel.
Beneficial effect：Compared with prior art, this utility model has advantages below：This utility model is by folder first
In vivo portion sets up interior axle to head, collet interior formed can precise positioning parts to be processed active force, improve clamping workpiece
Stability, further enhancing the durability and significant increase service life of chuck of chuck；Secondly by interior axle itself
Screw thread, using the screw thread simultaneously more efficient fixation for realizing interior axle and collet body inwall of tight mode, improves clamping efficiency, further
Improve the efficiency of production and processing.

Fig. 2 is the sectional view of interior axle in this utility model；
Fig. 3 is the sectional view of chuck in this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings the technical solution of the utility model is described further.
As shown in Figure 2 to 3, a kind of high accuracy chuck with accurate interior positioning function of this utility model, including chuck
Body 1 and the interior axle 2 for positioning parts to be processed 3 inside collet body 1, wherein interior axle 2 in collet body 1 form one and support
The firmly axial force of parts to be processed.Collet body 1 and interior axle 2 in this utility model is spring steel.This utility model leads to
Cross, collet interior formed can precise positioning parts to be processed active force, improve clamping
The stability of workpiece, further enhancing the durability and significant increase service life of chuck of chuck.
Wherein, one end outer wall of collet body 1 has the conical surface 101, the collet body 1 near the end of the conical surface 101 from outside to inside
Include the first shoulder hole 102, the second shoulder hole 103 and the 3rd screwed hole 104 successively, wherein first shoulder hole 102 is use
In the clamping endoporus of clamping parts to be processed.Interior axle of the present utility model 2 includes threaded portion 201 and thin rod part 202, wherein, institute
State threaded portion 201 to screw in the 3rd screwed hole 104, thin rod part 202 is stretched in the second shoulder hole 103.In order to realize interior axle 2 with folder
The quick-clamping of head body 1, the end face in the threaded portion 201 of interior axle 2 are provided with the convenient notch 203 for screwing in interior axle.It is easy to user
Quickly interior axle 2 is screwed in chuck body by operation instrument, position parts to be processed.In order to preferably prop up parts to be processed,
Chamfering 204 is offered in the end face of the thin rod part 202 of interior axle 2.Screw thread of this utility model by interior axle itself, using screw thread simultaneously
The more efficient fixation for realizing interior axle and collet body inwall of tight mode, improves clamping efficiency, further increases production and processing
Efficiency.
The course of work：A kind of high accuracy chuck with accurate interior positioning function of this utility model is arranged on special machine,
Part to be processed is inserted and is passed from the first shoulder hole 102, is stretched in the second shoulder hole 103；Interior axle 2 is revolved using operation instrument
Enter in collet body 1, parts to be processed is propped up inside collet body, realize fixed in the chuck of parts to be processed.Peripheral hardware is screwed again
Chuck screw thread, 101 forced contraction of the conical surface, by the first shoulder hole 102 processing part clamp, be easy to process the part, fit
For producing in batches, generic way is difficult the workpiece of clamping, quickly realizes clamping, improve production efficiency in production line.
