Problems solved by technology

[0006] In order to overcome the problem in the prior art that the operator needs to enter the internal patch of the cylindrical workpiece due to the use of the ray source in the external single-wall transillumination, and the operator cannot enter the internal patch due to the small diameter of the workpiece, so only a low sensitivity can be used For the problem of transillumination on the outer double wall of the ray source, the present invention proposes a magnetic adsorption patch device

Embodiment Construction

[0027] This embodiment is a magnetic adsorption type patch device.

[0028] Such as figure 1 As shown, this embodiment includes a suction component 1 and a patch component 2, and the suction component is used in conjunction with the patch component.

[0029] The patch assembly 2 is connected to the support frame 3 of the suction assembly 1 by bolts 7 and can slide along the support frame 3. A plurality of magnets 4 are arranged on the inner surface of the vertical plate of the support frame 3, and the magnets 4 are fixed on the support frame 3 through a magnet fixing cover 5; The magnetic adsorption type patch device is adsorbed on the workpiece. In this embodiment, the number of the magnets is three.

[0030] The adsorption assembly 1 includes a support frame 3, three magnets 4 and three magnet fixing covers 5. In this embodiment, both the support frame 3 and the magnet fixing cover 5 are made of aluminum alloy materials, and the magnet 4 is made of magnets. The support frame 3 ...

Abstract

A magnetic adsorption type surface mounting device comprises an adsorption assembly and a surface mounting assembly. The surface mounting assembly is arranged on a supporting rack in the adsorption assembly, and the surface mounting assembly can slide on the supporting rack in the adsorption assembly, and is fixed on the supporting rack in the adsorption assembly through a locking nut. The adsorption assembly adsorbs the device on the internal surface of a longitudinal weld in a cylindrical workpiece made of a ferromagnetic material, and the surface mounting device makes a camera bag filled with films closely mounted on the internal surface of the detected segment of the longitudinal weld. The surface mounting operation of the internal surface of the longitudinal weld in the cylindrical workpiece made of the ferromagnetic material is completed outside the workpiece, so an operator is prevented from entering the workpiece during surface amounting, and the labor intensity is reduced. Thedevice reduces the lower limit value of the internal diameter of the cylindrical workpiece of a useable source in an outer single-wall viewing scheme, and avoids the reduction of the detection sensitivity of the workpiece, caused by a used source in outer double-wall viewing. The device has the advantages of simplicity in operation, rapidness and accuracy in close mounting of the camera bag filled with the films on the internal surface of the longitudinal weld in the cylindrical workpiece, close lamination of the films to the weld, improvement of the detection efficiency, and high detection sensitivity.

Description

Technical field [0001] The invention relates to the field of radiation detection, in particular to a magnetic adsorption type patch device. Background technique [0002] The pressure vessel industry and the aerospace industry often manufacture cylindrical workpieces with longitudinal welds as product parts. This cylindrical workpiece with longitudinal welds is mostly made of steel sheet welding made of ferromagnetic materials. The longitudinal welds are the weak areas of the product. Under normal circumstances, the welds and their heat-affected zones must be internally welded. Quality inspection. Radiographic inspection is a commonly used method for internal quality inspection of longitudinal welds of cylindrical workpieces. Under normal circumstances, there are three options for radiographic inspection of longitudinal welds of cylindrical workpieces: the radiation source is internal single-wall transillumination, the radiation source is external single-wall transillumination, ...
