Abstract

The invention discloses an air tightness detection device. The air tightness detection device comprises a detection table, an air source, a pressure sensor, a heater, a controller and a power supply, wherein the detection table is provided with a detection cavity for accommodating a detected part; the air source is communicated with the detection cavity, and is used for supplying detection gas to the detection cavity; the pressure sensor is used for detecting the pressure in the detection cavity; the heater is arranged on the detection table, and is used for heating the gas in the detection cavity; the controller is connected with the heater and the pressure sensor respectively, and is used for controlling the heater and receiving a pressure feedback signal of the pressure sensor; the power supply is connected with the heater and the controller respectively in order to supply power to the heater and the controller. By adopting the air tightness detection device according to the embodiment of the invention, air tightness detection at a normal temperature can be realized, and air tightness detection at a high temperature can be realized; the air tightness detection device has the advantages of wide application range, high practicability and the like.

Description

technical field [0001] The invention relates to the field of equipment detection, in particular to an air tightness detection device. Background technique [0002] In modern manufacturing, it is often necessary to test the air tightness of some parts. For the automobile manufacturing industry, in the design and production process, whether the airtightness of the intake system, the oil supply system, and the cylinder block can be guaranteed will directly affect the performance of the car. Therefore, the air tightness testing of components has become an important safety testing requirement. However, the existing air tightness detection devices have a small application range and poor practicability, and there is a need for improvement. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. For this reason, an object of the present invention is to propose a kind of a...
