Description
Technical Field
The utility model belongs to the technical field of nondestructive testing, and particularly relates to a sealing clamp for DR/CT (digital radiography) detection.
Background
The industrial DR/CT nondestructive testing equipment mainly uses Co-60 radioactive source rays and X rays to carry out area array or linear array scanning on industrial products, and reconstructs to obtain a three-dimensional model thereof, thus obtaining the internal defect distribution thereof. In order to ensure the detection effect, a special fixture is required to be designed. The clamp has basic fixing and sealing functions, reduces attenuation of detection rays as much as possible, and ensures clear detection effect.
Disclosure of Invention
At present, in the DR/CT nondestructive testing process, a proper clamp is lack for detecting a sample in a hemisphere or a whole sphere, so that the sealing and stable fixation of the detecting sample can be realized, and the interference to rays can be avoided, and the detecting effect is influenced. The utility model aims to provide a sealing clamp for DR/CT detection, which can solve the problems of fixing and sealing a detection sample and ensure the detection effect.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
A sealing clamp for DR/CT detection, wherein a clamp shell is connected with a clamp gland for sealing; the clamping ring is used for integrally connecting the clamp shell and the clamp gland which are connected and sealed with the cylinder bottom table.
The fixture is made of polytetrafluoroethylene.
The wall thickness of the clamp is 1-3 mm.
The clamp shell and the clamp gland are sealed through threaded connection.
The compression ring is connected with the cylinder base table through threads.
The edge of the clamp gland is pressed in the annular groove protruding from the center of the cylinder base table by the pressing ring.
The beneficial effects obtained by the utility model are as follows:
The clamp can firmly and vertically erect the detected product on the detection platform, and cannot deviate due to the mechanical movement of the platform; the surface scratch and the scratch of the product can not be generated; accidents such as overturning and the like can not occur; the accident of product material leakage can not occur; on the straight line path of the ray source and the detector, the clamp reduces the shielding of the detected object as much as possible. The unavoidable parts are selected from materials with low density, small equivalent thickness and low atomic number, the materials are uniformly distributed, and the density is not more than 2g/cm 3. And the size of the tool part is reduced/thinned as much as possible while ensuring the strength requirement of the tool so as to reduce the attenuation effect on the detection rays. Good detection effect is ensured.
Drawings
FIG. 1 is a schematic illustration of a sealing fixture for DR/CT detection;
In the figure: 1. a clamp housing; 2. a clamp gland; 3. a compression ring; 4. a cylindrical base table.
Detailed Description
The utility model will now be described in detail with reference to the drawings and specific examples.
A clamp for DR/CT nondestructive testing is suitable for hemispherical or whole ball products. The clamp is made of polytetrafluoroethylene. The piece to be detected is sealed to be placed in the clamp, the clamp is inverted on the cylinder bottom table, and fixed connection is achieved through the compression ring. The cylinder bottom table is bonded or bolted with the gasket. The gasket is then connected to the connection turntable by bolts. The connecting turntable is connected with the rotating platform through bolts. The thickness of the wall of the clamp is set to be 1-3 mm in order to reduce the attenuation effect of the clamp on the detected rays while ensuring the strength.
A sealing clamp for DR/CT detection is used in DR/CT detection process for holding detection sample.
As shown in fig. 1, a sealing clamp for DR/CT detection, wherein in the DR/CT detection process, a clamp housing 1 and a clamp gland 2 are sealed by threaded connection, and are used for containing a detection sample; the clamping ring 3 is used for integrally connecting the clamp shell 1 and the clamp gland 2 which are connected and sealed with the cylinder bottom table 4, the clamping ring 3 is connected with the cylinder bottom table 4 through threads, the edge of the clamp gland 2 is pressed in the annular groove protruding in the center of the cylinder bottom table 4 by the clamping ring 3, and the clamp shell 1 and the clamp gland 2 are integrally fixed. The cylindrical base table 4 is used for the support of the clamp housing 1 and the clamp gland 2 as a whole.
This patent has been described with reference to specific embodiments thereof. It will be apparent that various modifications and variations can be made without departing from the spirit and scope of the utility model. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
