Description
Technical field
The utility model is related to a kind of clamping tooling, specifically a kind of self-centering tooling of fast positioning clamping belongs to
Part processing clamp 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 tooling, causes product hole size precision and thick
Rugosity is unqualified.
Invention content
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of self-centering work of fast positioning clamping
Dress, can improve processing efficiency, and product appearance beauty, nothing is made to connect tool marks.
According to technical solution provided by the utility model, a kind of self-centering tooling of fast positioning clamping includes claw and positioning
Plate, it is characterized in that：Three claws are distributed along same even circumferential constitutes disc-shaped structure, by multiple solid in the middle part of each claw
Surely 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 positioning plates are distributed along same even circumferential constitutes disc-shaped structure；It is formed between three positioning plate medial surfaces round
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 utility model has the following advantages：
The utility model is simple in structure, compact, reasonable, can improve processing efficiency, and product appearance beauty, nothing is made to connect knife
Trace；Cause relatively low, easy to operate, integral rigidity is good.
Description of the drawings
Fig. 1 is the utility model front view.
Fig. 2 is the utility model side view.
Reference sign：1- claws, 2- fixing bolts, 3- positioning plates, 4- fastening bolts, 5- positioning pins, 6- internal threads,
7- positioning chambers, 8- stop bits end face.
Specific implementation mode
The utility model will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1 and 2, the utility model includes mainly claw 1 and positioning plate 3, and three claws 1 are equal along same circumference
Even distribution constitutes disc-shaped structure.
1 middle part of each claw is fastened on by multiple fixing bolts 2 on the chuck of lathe, and 1 inside of each 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 constitutes 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, and 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 and lower position positioning of thin-wall rotation-type part installation.
The operation principle of the utility model is：First, three claws are mounted on chuck, screw fastening bolt.Then
Three positioning plates are connected on three claws, then positioning pin and fastening bolt are installed.Three claws are in clamped condition
When, according to part external screw thread with interior screw thread on connecting plate, until reaching 6H/6h.By part by being threaded into positioning plate,
Until end face is bonded, part at this moment can be processed, part can be taken out by unclamping three claws after processing is completed.
The utility model is simple in structure, compact, reasonable, can improve processing efficiency, and product appearance beauty, nothing is made to connect knife
Trace；Cause relatively low, easy to operate, integral rigidity is good.
