Detailed Description

The preferred embodiments of the present utility model will be described in detail below with reference to the attached drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

Referring to fig. 1-4, a volute processing positioning tool of a turbocharger comprises a base 1, a first limiting groove 101 is formed in the middle of the base 1, limiting parts 2 are arranged at positions, corresponding to notches at two ends of the first limiting groove 101, on the base 1, of the base 1, a stop block 3 for limiting a volute 7 is fixed on one side of the upper end face of the base 1, a guide rail 4 is fixedly arranged on the other side of the base 1, and a limiting seat 5 for limiting the volute 7 is arranged on the guide rail 4 in a sliding mode.

The profile of the first limit groove 101 is matched with the processed volute 7, the notch formed by the same second limit groove 201 is also matched with the processed volute 7 end flange profile, after the volute 7 is placed on the base 1, the through hole of the volute 7 end flange corresponds to the limit hole 202, and the limit pin 6 can be inserted into the limit hole 202 through the through hole of the volute 7 end flange to limit the position of the volute 7 end flange.

A second limit groove 201 is formed in one side end of the limit part 2 corresponding to a notch at one end of the first limit groove 101, a limit hole 202 is formed in the second limit groove 201, and a limit pin 6 is inserted into the limit hole 202; the stop block 3 is obliquely arranged towards one side of the first limit groove 101;

the limiting hole 202 and the limiting pin 6 are preferably cylindrical structures, and can also be other structures, such as triangular prism structures, pentagonal prism structures and the like, so long as the limiting hole 202 is inserted to limit the shaking of the end flange of the volute 7.
