Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a clamping mechanism for nondestructive testing. Background Art

[0002] Nondestructive testing refers to a method of inspecting and testing the structure, properties, state and type, nature, quantity, shape, position, size, distribution and changes of defects inside and on the surface of the test piece by using physical or chemical methods, with the help of modern technology and equipment, without damaging or affecting the performance of the tested object or the internal organization of the tested object, by utilizing the changes in heat, sound, light, electricity, magnetism and other reactions caused by abnormal internal structure or defects of the material.

[0003] Application No. 202220211621.4 discloses a clamping mechanism for non-destructive testing of steel parts, which places a square steel part in a U-shaped placement groove, starts the first drive cylinder, and the output end of the first drive cylinder is extended. The U-shaped placement groove is located between two sets of quick clamps. The square steel part is clamped and limited by the quick clamp, the output end of the first drive cylinder is shortened, the U-shaped placement groove is reset, and the drive motor is started. The drive motor drives the return frame to rotate 90 degrees, so that the square steel part is in a vertical state, and the mechanical slide is started. The mechanical slide sends the square steel part into the non-destructive testing equipment, and the square steel part can be non-destructively tested. When the square steel part is unloaded after non-destructive testing, the mechanical slide is reset, and the unloading of the square steel part can be completed by loosening the two sets of quick clamps, which facilitates the loading and unloading of square steel parts, reduces the amount of manual operation, and improves the efficiency of non-destructive testing of steel parts.

[0004] After optimization, the clamping mechanism for non-destructive testing of steel parts in the above application uses two sets of quick clamps to clamp the square steel pipe workpiece, which results in the two sets of clamps not being able to clamp the cylindrical steel pipe firmly enough when facing the cylindrical steel pipe, and there is a risk of it falling off.
