Technical Field

[0001] This utility model relates to the field of welded component strength testing technology, specifically a welded component strength testing device. Background Technology

[0002] Welding strength testing equipment is a specialized device used to evaluate the strength performance of welded joints and welded structures. By applying different forms of load to the welded parts, it tests the strength performance of the welded parts under various stress conditions, including the tensile strength, compressive strength, bending strength, and shear strength of the welded joints, in order to evaluate the welding quality and the reliability of the welded parts.

[0003] If the contact between the fixture and the surface of the weldment is uneven or the clamping force is uneven, it will cause abnormal local stress on the weldment during the test, so that the test results cannot truly reflect the actual strength of the weldment. Therefore, we propose a weldment strength testing device. Utility Model Content

To achieve the above objective, this utility model provides the following technical solution: a weldment strength testing device, including a fixing frame, wherein a fixing component is provided on the top of the fixing frame;

[0005] The fixing assembly includes four connectors, which are respectively fixedly connected to the top of the fixing frame. The four connectors are symmetrically distributed on the top of the fixing frame. A fixing base plate is fixedly connected to the interior of the four connectors.

It can reduce test preparation time and the number of test interruptions caused by clamping problems, making the test process smoother and improving overall test efficiency.

[0006] A clamping and limiting assembly is disposed at the top of the groove. The clamping and limiting assembly includes four fixed clamping bases, which are respectively fixedly connected to the top of the groove.

[0029] The transmission assembly 4 includes a sliding block 401, which is movably connected inside the sliding groove 205. First, by rotating the rotating shaft 403, the movable clamping top seat 302 is rotated and opened, and the weldment to be tested is placed on the fixed clamping base 301. After placement, by rotating the rotating shaft 403, the movable clamping top seat 302 is fastened onto the weldment, and the limiting bead 305 is connected to the weldment.

After placement, by rotating the rotating shaft 403, the movable clamping top seat 302 is fastened onto the weldment, and the limiting bead 305 connects to the weldment. When a tensile test is required on the weldment, the transmission gear 407 is rotated to drive the fixed rack 306 to translate, simultaneously causing the limiting bead 305 to pull the weldment under tension. The test involves recording data via pressure sensor 307, with the data displayed on control panel 206.
