Abstract

The invention discloses a welding spot test piece tearing test fixture which comprises a torsional mechanism, a fixed mechanism, a lead screw and a fixed sleeve, wherein the torsional mechanism comprises a clamping plate and an operating rod; a clamping groove is formed in one end of the clamping plate; the other end of the clamping plate is fixedly connected with the operating rod; the fixed mechanism comprises a fixed block and a slide block; the slide block is connected with the fixed block in a sliding manner; a baffle plate is arranged at the lower part of the slide block; a through hole is formed in the baffle plate; a separation blade is fixedly arranged on the lead screw; a long axis segment is arranged at the left end of the separation blade, a short axis segment is arranged at the right end of the separation blade, the long axis segment is in threaded connection with the fixed block and the short axis segment passes through the through hole; the baffle plate is propped against the baffle plate; the fixed sleeve is fixedly connected with the short axis segment; and the fixed sleeve is propped against the baffle plate. According to the welding spot test piece tearing test fixture, clamping and testing of a test piece are achieved, the problem that the test piece is not easy to tear through double hands in the prior art is solved, meanwhile, the fixture is simple and convenient to operate and the work efficiency of the staff is improved.

Description

technical field [0001] The invention relates to the technical field of welding quality detection, in particular to a tearing test tool for a solder joint test piece. Background technique [0002] The welding process is one of the most commonly used processes in automotive production. Among them, the quality of the solder joints is not only related to whether the strength of the solder joints of the body-in-white meets the standard, but more importantly, it will affect the strength of the whole vehicle. Therefore, after the welding is completed, the strength of the solder joint must be checked. The current inspection methods mainly include visual inspection, non-destructive inspection, destructive inspection and ultrasonic inspection which is being promoted. Although many problems can be found in visual inspection and non-destructive inspection, the inspection is not reliable due to the simplicity of the method. Ultrasonic examination is still in the development stage, imma...
