Lower part is L-shaped and is stuck in the chuck, the top of first chuck jaw and lower vertical；The upper end of first chuck jaw
Portion is uniformly arranged some into a word and the pin hole of symmetric arrays in vertical direction；The portion of setting is the positioning of centrum in the pin hole
Pin, the positioning pin are fixed in the pin hole by bolt light pad；
The second chuck jaw lower part is L-shaped to be stuck in the chuck, and the top of second chuck jaw is hung down with lower part
Directly, and the upper end of the L-type is equipped with groove.
Under preferred embodiment, the line of two first chuck jaws and two second chuck jaws is in cross.
Under preferred embodiment, the pin hole number is the odd number more than or equal to 1.
Under preferred embodiment, some pin holes are symmetrically arranged on the two of the pin hole using 1 middle pin hole as axis
Side.
The present invention positions valve flange to be processed, can automatically determine it and cast central plane, the first card of the present invention
The positioning pin set on disk pawl is conical head, and suitable for various types of valve flange structures, clamping is accurate, and described fixed
It is connected by screw bolts between position pin and first chuck jaw, facilitates dismounting and change.Efficiency of the present invention is very high, and simple in structure,
Centering is accurate.

Embodiment
The structure of the present invention is as follows：
As shown in Figure 1, the present invention includes chuck 1 and chuck jaw, surrounding is symmetrical arranged the first card in interval on the chuck 1
2 and second chuck jaw of disk pawl 7 each two；First chuck jaw, 2 lower part is L-shaped and is stuck in the chuck 1, first card
The top of disk pawl 2 and lower vertical；It is some into a word and right that the upper end of first chuck jaw 2 is uniformly arranged in vertical direction
Claim the pin hole 5 of arrangement；The portion of setting is the positioning pin 6 of centrum in the pin hole 5, and the positioning pin 6 is fixed by 3 light pad 4 of bolt
In the pin hole 5；Second chuck jaw, 7 lower part is L-shaped to be stuck in the chuck 1, the top of second chuck jaw 7
With lower vertical, and the upper end of the L-type is equipped with groove 8.
As shown in Fig. 3, Fig. 5, the lower part of L-type is stuck in the chuck 1 described in first chuck jaw 2, the L-type it is upper
Portion perpendicular to the lower part of the L-type, and L-type upper end described in first chuck jaw 2 vertical direction be uniformly arranged it is some into
One word and the pin hole of symmetric arrays 5.
Described 5 numbers of pin hole are odd number for the number of the odd number more than or equal to 1, and some other described pin holes 5 are with centre
1 pin hole 5 be axis, be symmetrically arranged on the both sides of the pin hole 5.The portion of setting is the positioning pin of centrum in the pin hole 5
6, the positioning pin 6 is fixed in the pin hole 5 by 3 light pad 4 of bolt.
6 top of positioning pin is cylinder, and lower part is centrum, sets at the top of the cylinder and matches with the bolt 3
Internal thread, the centrum of lower part is suitable for the valve body perforate of different model, within the specific limits with suitability.
Under normal conditions, two positioning pins 6 are threaded through two symmetrical pins on first chuck jaw 2 respectively
In hole 5, but described 6 numbers of positioning pin are not excluded for as one or multiple situations about being threaded through in the pin hole 5.
As shown in figure 4, L-type lower part described in the second chuck jaw 7 is stuck in the chuck 1, the top of L-type and the described second card
