A welding slit detection device utilizing an X-ray machine

Abstract

A welding slit detection device utilizing an X-ray machine is disclosed. The device includes a tank body. One side wall of the tank body is provided with an opening. The opening of the tank body is hinged with a tank door. The top inner wall of the tank body is provided with a support. The lower surface of the support is provided with X-ray tubes. The inner wall of the bottom of the tank body is provided with an annular track. Two mobile gears are movably mounted in the annular track, and are at two sides of the annular track. Tops of the mobile gears are welded to supporting bars. A supporting plate is fixed between the two supporting bars. The middle of the inner wall of a bottom plate of the tank body is provided with a first motor. The tail end of an output shaft of the first motor isconnected to the supporting plate. The device is simple in structure, novel in design, high in precision and low in error, can rapidly determine whether a welded part has a slit or not through the X-ray tubes. The device allows a battery to be radiated by X-ray comprehensively and evenly so that the detection structure is more precise and a detection range is more comprehensive.

Description

technical field [0001] The invention relates to the technical field of gap detection devices, in particular to X-ray machine welding gap detection equipment. Background technique [0002] An X-ray machine is a device that generates X-rays. It is mainly composed of an X-ray tube, an X-ray machine power supply, and a control circuit. The X-ray tube is composed of a cathode filament, an anode target, and a vacuum glass tube. The X-ray machine power supply It can be divided into two parts: high-voltage power supply and filament power supply. The filament power supply is used to heat the filament. The high-voltage output terminals of the high-voltage power supply are respectively clamped at both ends of the cathode filament and the anode target to provide a high-voltage electric field to accelerate the flow of active electrons on the filament. The anode target forms a high-speed electron flow. After bombarding the anode target surface, 99% of it is converted into heat, and 1% is ...
