Description

Technical Field

[0001] The utility model relates to the technical field of casting flaw detection, in particular to an automatic positioning clamping mechanism used for casting flaw detection. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance. During the production and processing of castings, the castings need to be clamped and fixed, and then subjected to flaw detection.

[0003] For example, the authorization announcement number "CN217143667U" is an automatic positioning and clamping mechanism for flaw detection of castings. The automatic positioning and clamping mechanism for flaw detection of castings, through the cooperation between the first motor, circular plate, vertical block, annular rod, flaw detection head, screw and vertical block, the output shaft of the first motor drives the circular plate to rotate, the circular plate drives the annular rod to reciprocate through the vertical block, and the annular rod drives the flaw detection head to reciprocate, so as to perform flaw detection on tubular castings. Before use, the user can turn the handle at the end of the screw, which solves the problem that the prior art cannot adjust the stroke of the flaw detection head to meet the usage requirements in different situations. However, the automatic positioning and clamping mechanism used for casting flaw detection uses the cooperation of springs to position and clamp the castings when automatically positioning and clamping the castings. The elastic coefficient of the springs will be damaged after long-term use, affecting the subsequent positioning and clamping of the castings. At the same time, the automatic positioning and clamping mechanism used for casting flaw detection uses the cooperation of screws to reciprocate when the flaw detection head moves back and forth to perform flaw detection. The connection of the screws is prone to loosening when connected for a long time, which reduces the service life of the equipment. Utility Model Content
