Airtightness tester for vacuum pump assembly line

Abstract

The invention discloses an airtightness tester for a vacuum pump assembly line. The airtightness tester comprises an assembly body and a control platform. The assembly body is provided with a bearing board; the center of the bearing board is provided with a positioning lifting mechanism; the top surface of the positioning lifting mechanism is used for bearing a station plate from a slide rail of the vacuum pump assembly line; the station plate is used for holding a pump body; a displacement sensor is arranged beside the positioning lifting mechanism; the positioning lifting mechanism is used for lifting the station plate from a slide groove of the slide rail to a place for detection; the displacement sensor is connected with the control platform through a data transmission antenna; a sealing mechanism for sealing and pressing the pump body is arranged right above the station plate; the sealing mechanism is internally provided with a pressure detection device; the sealing mechanism and the displacement sensor are connected with the control platform; and the control platform is used for controlling operation of the sealing mechanism. The beneficial effects are that the airtightness tester realizes cooperation use with a general assembly line body of the vacuum pump assembly line, and detection speed is improved.

Description

technical field [0001] The invention relates to vacuum pump testing equipment, in particular to an air tightness testing machine used in a vacuum pump assembly line. Background technique [0002] In the vacuum pump assembly line, the parts in the pump body and pump cover are installed. After the pump body and pump cover are installed, the air tightness of the pump body needs to be tested for testing, so an air tightness testing machine is used for testing. In the prior art, the air tightness testing machine includes a sealing and pressing mechanism. After the sealing and pressing mechanism compresses and seals the chamber to be tested, gas is introduced into the chamber to be tested. Detect whether the pressure in the cavity to be tested changes to judge whether the airtightness of the cavity to be tested is good or not. However, the device has the following disadvantages: the device cannot cooperate with the slide rail of the general assembly line body in the vacuum pump a...

In the prior art, the air tightness testing machine includes a sealing and pressing mechanism. After the sealing and pressing mechanism compresses and seals the chamber to be tested, gas is introduced into the chamber to be tested. Detect whether the pressure in the cavity to be tested has changed to judge whether the airtightness of the cavity to be tested is good or not

However, the disadvantages of this device are: the device cannot cooperate with the slide rail of the general assembly line body in the vacuum pump assembly line, and cannot improve the processing speed of the entire vacuum pump assembly line
