Welding tightness detection machine and method using detection machine to detect welding tightness

Abstract

The invention relates to a welding tightness detection machine. The welding tightness detection machine comprises a work table, a liquid container which is arranged at the lower part of the work table, a workpiece placing tooling, a vertical movement device which is connected with the workpiece placing tooling and drives the workpiece placing tooling to vertically move to enable the workpiece placing tooling to lift together with a workpiece to come into or out of a container, a sealing positioning device which is arranged at the upper part of the workpiece placing tooling, a workpiece rotation device, a pressurizing mechanism which is arranged on the workpiece placing tooling, and a control device which is in communication connection with the vertical movement device, the sealing positioning device and the pressurizing mechanism. The invention further discloses a method using the detection machine to detect welding tightness. Through a first cylinder and a second cylinder, the welding tightness detection machine realizes the whole processes of workpiece clamping and positioning and tightness detection. The whole device has the advantages of simple structure, reliable work and simple process, and is particularly suitable for the tightness detection of a cylinder, a fuel tank, a welding pipe and the like.

Description

technical field [0001] The invention relates to an air-tightness testing machine, in particular to a welding air-tightness testing machine and a method for testing welding air-tightness using the testing machine. Background technique [0002] The air pressure detection method is usually used to detect the sealing of pipe fittings welding, but the commonly used air pressure detection device adopts manual clamping and manual connection of the pressurized gas pipeline, and uses the cylinder to drive the workpiece into the container for airtightness detection. Whether it is reliable or not, it must be observed by rotating around the workpiece continuously. Moreover, the existing detection machine has a complex structure, low working reliability, cumbersome clamping and fixing, and low production efficiency. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a welding air tightness testing machine ...
