Supercharger volute flow channel volute tongue to reference hole center inspection tool and detection method

Abstract

The present invention relates to a supercharger volute channel volute tongue to the center of the reference hole, including a positioning block, the bottom of the positioning block forms an insertion block, and an assembly step is formed between the insertion block and the bottom surface of the positioning block; and a horizontal The rotating mechanism and the measuring head; the positioning block rotates and cooperates with the volute of the supercharger to drive the measuring head at the detection position to rotate in front of the volute tongue, and then detect whether the distance between the volute tongue and the center of the reference hole is qualified. The detection method adopts the above-mentioned checking tool; it includes the following steps: first pull out the limit pin in the checking tool, rotate the measuring head; put it into the volute; then turn the measuring head back to its original position, and insert the limiting pin into the pin Fix the probe at the detection position of the inspection tool; rotate the entire inspection tool, when the probe passes the tongue tip of the volute, the pass gauge should pass through smoothly, and the stop gauge should be stuck, which means the test is qualified, otherwise it is unqualified . It is easy to operate, and can realize online rapid detection on the production line, increase the frequency of detection, and reduce bad outflow.

Description

technical field [0001] The invention relates to the field of detection of auto parts, in particular to a detection tool and a detection method for a turbocharger volute channel volute tongue to the center of a reference hole. Background technique [0002] Such as figure 1 As shown, the connection between the volute and the air outlet often has a "tongue-like" structure formed by the shell wall and shaped like a tongue, called the volute tongue. Its function is to place part of the gas to circulate in the volute. When the airflow at the outlet of the blade channel of the rotating impeller brushes near the volute tongue, the tongue of the volute tongue divides them into two: most of the airflow flows along the channel to the outlet of the fan; a small part of the airflow passes between the volute tongue and the impeller. The gap between them flows back to the volute, and returns to the volute tongue to participate in the new shunt after rotating with the impeller for one wee...
