Automatic leak detecting device

Abstract

The invention discloses the part crack detecting or sand hole field, and in particular relates to an automatic leak detecting device in order to overcome a defect that a conventional leak detecting device is poor in universality and cannot measure the leakage degree of parts. The invention provides an automatic leak detecting device which comprises a base, a frame, a hood, a control cabinet, a man-machine interface, and a device mechanical body. The man-machine interface is located on the right side of the hood, and comprises an absolute differential pressure sensor, a differential pressure sensor, a temperature sensor, an input keyboard, a printer, a display device, and a MODBUS communication device. The frame is disposed in the hood and is used for supporting the device mechanical body. The device mechanical body comprises a support platform, a clamp, a horizontal sealing device, a vertical sealing device, and an air inflow detecting device. The automatic leak detecting device can be used for detecting the leaks of different parts, provides efficiency, saves cost, and achieves quantitative data collection and remote data transmission.

Description

technical field [0001] The invention relates to the field of detecting cracks or sand holes in parts, in particular to an automatic leak detection device. Background technique [0002] At present, there are many equipments widely used for air tightness testing, but each part needs a leak testing equipment, and the same equipment cannot adapt to the leak testing of various parts, so it is necessary to redesign and develop one-to-one corresponding fixtures and software , that is, the generality of the leak detection equipment is poor, which will inevitably lead to a waste of time and resources, as well as an increase in production costs. In addition, the existing leak detection equipment cannot measure the degree of air leakage of the parts, resulting in the inability to collect the leak detection equipment Relevant parameters about airtightness, so that the parts cannot be reworked and remedied according to the feedback data. Contents of the invention [0003] In view of t...
