Testing tool and testing method for rigidity of clamp movable positioning mechanism

Abstract

The invention discloses a testing tool and a testing method for the rigidity of a clamp movable positioning mechanism, belonging to the technical field of automobile welding clamps. The testing tool comprises a magnetic base (1), a support plate (2), a support rod (3), a sliding wheel mechanism (4), a traction part (5) and a balancing weight (6), wherein the magnetic base (1), the support plate (2) and the support rod (3) are connected in sequence; a plurality of sliding wheel mechanism positioning structures (301) are arranged on the support rod (3) along the height direction, and the sliding wheel mechanism (4) is fixed on the support rod (3) through the sliding wheel mechanism positioning structures (301); the traction part (5) penetrates through the sliding wheel mechanism (4), a first end of the traction part (5) is connected with the balancing weight (6), and a second end of the traction part (5) is connected with a positioning element of the clamp movable positioning mechanism. According to the testing tool, the structure is simple, the operation is convenient, the inclining can be prevented without the manual applying of external force, the interference of the testing result caused by human factors can be avoided, and the testing accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing automobile welding fixtures, in particular to a tool and method for detecting the rigidity of a movable positioning mechanism of a fixture. Background technique [0002] Body welding is an important process step in the automobile manufacturing process. Since most of the body parts are thin-walled plates, it is necessary to use special welding fixtures to position and clamp the parts to be welded during the welding process, so as to ensure the correct assembly relationship between the body parts, and at the same time ensure the welding quality of the body and The smooth welding process ensures the assembly accuracy of the entire body. Therefore, welding fixtures play an important role in the body welding process. In order to enable the welding fixture to properly position the parts, the welding fixture includes movable positioning mechanisms, such as positioning pins and positioning block m...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: the rigid detection tool of the existing fixture movable positioning mechanism is prone to toppling during the detection process, and it is necessary to artificially apply external force to prevent the detection tool from falling over. The process is more complicated and will also affect the accuracy of the final test results
