Clamp for detecting gas tightness of automobile cooling pipe

Abstract

The invention discloses a clamp for detecting the gas tightness of automobile cooling pipes, comprising an aerator provided with an air faucet (25), a water tank (16), a left rotating shaft (1), a right rotating shaft (12), a supporting device, and a clamping device; the aerator is connected with the air source, the left rotating shaft (1) and the right rotating shaft (12) are respectively connected to the left end and the right end of the supporting device in a rotatable way; one end of the clamping device is connected with the left rotating shaft (1) via a connecting shaft I (3), and the other end thereof is connected with the right rotating shaft (12) via connecting shaft II (21); and the air faucet (25) is connected with the clamping device. With the adoption of the above structure, plural groups of cooling pipes can be installed for once, and simultaneously the gas tightness can be detected, thus greatly reducing labor intensity of workers and enhancing working efficiency; and atthe same time, the good gas tightness can avoid health of people from being harmed.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a fixture suitable for testing the airtightness of cooling pipes in various automobile cooling systems. Background technique [0002] Cars are generally cooled with water, mainly to ensure the normal operating temperature of the engine to prevent the engine from overheating. Usually the cooling pipes in the car are stainless steel pipes, which are assembled by many pipes and positioned by connecting plates. Therefore, in actual operation, workers will test the airtightness of the assembled cooling pipe, so a jig will be used to facilitate detection. This existing clamp for detecting the airtightness of the cooling pipe of an automobile comprises two sealing sleeves and an air intake nozzle, and the air intake nozzle is arranged on one of the sealing sleeves, so that the two ends of the cooling pipe are respectively covered with the sealing sleeve , Tighten the screw on the ...

AI Technical Summary

Problems solved by technology

[0003] ① Existing inspections are for a single cooling pipe, that is, workers test the airtightness of the cooling pipes one by one, and it is inconvenient to turn over the entire part, which greatly increases the labor intensity of the workers and reduces the Productivity

[0004] ②Since the two ends of the cooling pipe are only tightened by hand on the screw on the sealing sleeve, the clamping force at both ends is not enough, the sealing performance of itself is very poor, and the strength of the hand is not stable

[0005] ③ Existing inspections are carried out by putting the hands into the water manually. The workers have to soak their hands in the water for a long time when operating, which is not conducive to the health of the human body.
