Abstract

The invention discloses a tooling for detecting welding strength of stud welding. An upper support (2) is fixed at upper ends of two connecting guide rods (1), and a lower support (3) is fixed at lower ends; the middle part of the upper support (2) is sleeved with a thimble (4) from up to down; a bearing (5) is disposed below the thimble (4); two bearing guide rods (6) are sleeved with the lower support (3); a bearing block (7) is disposed below the lower support (3); two bolts (8) pass through the bearing block (7) from down to up and extend into corresponding bearing guide rods (6); a nut sleeve (9) is disposed between the two bolts (8); the upper end of the nut sleeve (9) is fixed with the lower support (3); the lower end of the nut sleeve (9) extends into a bearing sleeve (10). The invention has a simple structure, is convenient and rapid for operation, has accurate and reliable detection results, is applicable to destructive tests or non-destructive tests of stud welding strength, has wide application scope, and strong generality.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to a testing tooling for welding strength of stud welding. Background technique [0002] Stud welding is very common in the automotive industry. In order to ensure the reliability of the welding between the stud and the automotive panel, it is necessary to test the welding strength of the stud. At present, the general method is to use the tapping method to bend the stud by about 15 degrees, and then judge whether the welding strength meets the requirements according to whether there are cracks around the stud or not. On the one hand, the above methods are rough, poorly standardized, and time-consuming; on the other hand, there is no quantitative standard, and the test results are neither accurate nor reliable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stud welding welding strength detect...
