Direction finder air tightness test device
A test device, the technology of the directional device, which is applied to the liquid/vacuum degree for liquid tightness measurement, and by detecting the direction of the appearance of the fluid at the leakage point, can solve the problem of the inability to accurately detect the air tightness and water tightness of the directional device, and the stroke. The problem of large error and low pass rate for one-time inspection of products can achieve the effects of convenient product testing, high pass rate and simple structure

A direction finder air tightness test device comprises a bracket assembly used for supporting a direction finder under test, a sealing component used for sealing the two ends of the direction finder under test, a water tank, and a driving device used for driving the bracket assembly to move into / out of the water tank. The bracket assembly comprises a base bracket and a support frame mounted on thebase bracket. The sealing component comprises a fixed end cover and a movable end cover. The fixed end cover is mounted on a support seat, and the support seat is mounted on the base bracket. The movable end cover is connected with a cylinder. The cylinder drives the direction finder to do up-down reciprocating motion, and the air tightness and water tightness of the direction finder are detectedby stopping the direction finder at different positions in the water. The direction finder air tightness test device has the advantages of simple structure, convenient product detection, simple use,and high acceptance and qualification ratio of products.
Description
technical field [0001] The invention relates to an orienter air tightness test device. Background technique [0002] At present, when testing the airtightness and watertightness of the directional device, the operator manually operates it, and the underwater travel is judged by the operator based on work experience. During the detection process, the stroke error is large, and the airtightness of the directional device cannot be accurately detected. And water tightness, the pass rate of the product is not high. [0003] Therefore, be badly in need of inventing a kind of test device that can accurately detect the airtightness and watertightness of the orienter. Contents of the invention [0004] The object of the present invention is to provide an orienter airtightness test device for the airtightness and watertightness of the orienter, which can not only realize the airtightness test, but also be suitable for orientators with different outer diameters. [0005] The techni...
