Leak detection device for air chamber port of intercooler

Abstract

Provided is an intercooler air chamber port leak detection apparatus which comprises a support plate. Swing arms are hinged to both sides of the support plate. Claws are disposed on the lower ends of the two swing arms and connecting rods are hinged to the upper ends of the two swing arms. A cross bar is hinged between the two connecting rods. A cylinder is disposed under the cross bar. The piston rod of the cylinder is fixedly connected with the lower side of the cross bar. A through hole is disposed on the support plate. The cylinder passes through the through hole on the support plate and extends to the lower side of the support plate. A sealing disc is disposed on the lower end of the cylinder and is provided with air inlet. The intercooler air chamber port leak detection apparatus prevents a case that over high pressure intensity inside an air chamber pushes out the leak detection apparatus, reduces dangerousness, is easy to clamp, and greatly increases leak detection efficiency.

Description

technical field [0001] The invention relates to a leak detection device, in particular to a leak detection device for an air chamber port of an intercooler. Background technique [0002] In the production process of the intercooler, in order to ensure the quality of the product, it is necessary to conduct an airtight test on the intercooler, and the air inlet and outlet must be sealed during the airtight test. The current airtightness test adopted in the prior art is to expand the cylindrical sealant block by rotating the bolt method to realize sealing. This airtight test method has the following disadvantages: before the test, the operator needs to manually tighten the plugging head of each intercooler, and the tightening time of each is about 30 seconds, which greatly reduces the test efficiency; due to the airtight The test method is to rely on the sealing rubber pad to seal the air inlet and outlet of the intercooler. During the leak detection, the gas in the air chambe...

Problems solved by technology

This airtight test method has the following disadvantages: before the test, the operator needs to manually tighten the plugging head of each intercooler, and the tightening time of each unit is about 30 seconds, which greatly reduces the test efficiency; due to the airtight The test method is to seal the air inlet and outlet of the intercooler with the sealing rubber pad. During the leak detection, the gas in the air chamber is pushed upwards, and the sealing fixture is often pushed out, which may easily cause the danger of injury.
