Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to the positioning fixture structure of X-ray industrial testing equipment. Background Technology

[0002] X-ray industrial inspection equipment is mainly based on the penetrability of X-rays. X-rays are electromagnetic waves with very short wavelengths that can penetrate many substances that are not transparent to visible light. When X-rays penetrate the object being inspected, the intensity of the X-rays changes after passing through the object because different structures inside the object absorb X-rays to different degrees. The detector receives these X-rays with varying intensity, converts them into electrical and digital signals, and then processes and analyzes them through computer software to obtain images or related information about the internal structure of the object being inspected.

[0003] X-ray industrial inspection equipment requires the use of positioning fixtures. These fixtures ensure that the workpiece being inspected is accurately and permanently positioned within the equipment. This is because during the inspection process, specific parts of the workpiece need to be scanned repeatedly, or batch inspections of the same type of workpiece are required. For example, when inspecting precision gears in automotive parts, positioning fixtures can fix the gear in a specific position, ensuring that X-rays accurately irradiate key parts of the gear, such as the tooth root and tooth surface, during each inspection, thereby guaranteeing the accuracy and consistency of the inspection results.

[0004] Current X-ray industrial inspection equipment primarily relies on manual operation for workpiece positioning and clamping. Common types include screw clamps and eccentric clamps. Screw clamps utilize the rotation of a screw to generate clamping force; they are simple in structure, provide relatively large clamping force, and allow for precise control of the clamping force by adjusting the screw's engagement. Eccentric clamps achieve clamping through the rotation of an eccentric wheel, offering convenient and quick operation, but with relatively smaller clamping force. The reliance on manual operation for workpiece clamping, positioning, and disassembly is cumbersome and time-consuming, significantly impacting inspection efficiency, especially in batch testing. Existing technologies have introduced pneumatic, hydraulic, and electric drive systems to automate workpiece clamping, positioning, and disassembly, reducing manual operation. However, most clamps are designed for workpieces of specific shapes and sizes. When workpiece specifications change, the clamps may not adapt well, requiring redesign and replacement, leading to increased costs and reduced inspection efficiency. Utility Model Content

It aims to improve the problem that most fixtures in the prior art are designed for workpieces of specific shapes and sizes.
