Description
Technical field
The present invention relates to a kind of clamping toolings, specifically a kind of self-centering frock of fast positioning clamping, belong to part
Clamp for machining technical field.
Background technology
Thin-wall rotation-type part is since surface processing hardening is serious, so cutting force is especially big, traditional positioning method is
A pin on one side, not only clamping efficiency is low, and positioning accuracy is low, and the poor rigidity of frock, causes product hole size precision and thick
Rugosity is unqualified.
The content of the invention
It is an object of the present invention to overcome the above deficiencies, so as to provide a kind of fast positioning clamping self-centering frock,
Processing efficiency can be improved, product appearance beauty, nothing is made to connect tool marks.
According to technical solution provided by the invention, a kind of self-centering frock of fast positioning clamping includes claw and positioning plate,
It is characterized in that：Three claws are distributed along same even circumferential forms disc-shaped structure, passes through multiple fixations in the middle part of each claw
It is bolted on the chuck for being fixed on lathe, an arc-shaped positioning plate is connected by fastening bolt on the inside of each claw, three
A positioning plate is distributed along same even circumferential forms disc-shaped structure；It is formed between three positioning plate medial surfaces circular
Positioning chamber, three positioning plate inner side ends are equipped with internal thread.
Further, positioning pin is connected on positioning plate.
Further, stop bit end face is equipped on the inside of three positioning plates, the diameter of stop bit end face is more than positioning chamber diameter.
Compared with the prior art the present invention has the following advantages：
The invention has the advantages of simple structure, compactness and reasonable structure, can improve processing efficiency, and product appearance beauty, nothing is made to connect tool marks；Cause this
Relatively low, easy to operate, integral rigidity is good.

Specific embodiment
The present invention will be further described with reference to the embodiment in attached drawing below：
As shown in Figure 1 and 2, the invention mainly comprises claw 1 and positioning plate 3, three claws 1 are distributed structure along same even circumferential
Into disc-shaped structure.
Each 1 middle part of claw is fastened on by multiple fixing bolts 2 on the chuck of lathe, and each 1 inside of claw is logical
It crosses fastening bolt 4 and connects an arc-shaped positioning plate 3, three positioning plates 3 are distributed along same even circumferential forms disc
Structure.
Circular positioning chamber 7 is formed between three positioning plates, 3 medial surface, thin-wall rotation-type part is mounted on positioning chamber
In 7, three 3 inner side ends of positioning plate are equipped with internal thread 6, the external screw thread and internal thread that thin-wall rotation-type part passes through outer surface
6 screw.
Positioning pin 5 is connected on the positioning plate 3, the location and installation of positioning plate 5 is realized by positioning pin 5.
Three positioning plates, 3 inside is equipped with stop bit end face 8, and the diameter of stop bit end face 8 is more than 7 diameter of positioning chamber, stop bit
The setting of end face 8 can realize the upper-lower position positioning of thin-wall rotation-type part installation.
The present invention operation principle be：First, three claws are mounted on chuck, screw fastening bolt.Then by three
A positioning plate is connected on three claws, then installs positioning pin and fastening bolt.When three claws are in clamped condition, root
Match somebody with somebody interior screw thread on connecting plate according to part external screw thread, until reaching 6H/6h.By part by being threaded into positioning plate, to end
Face paste is combined into only, at this moment can process part, and three claws are unclamped after machining can take out part.
The invention has the advantages of simple structure, compactness and reasonable structure, can improve processing efficiency, and product appearance beauty, nothing is made to connect tool marks；It makes
Cost is relatively low, easy to operate, and integral rigidity is good.
