[0026] The present utility model provides a shear force test fixture, Figures 1 to 3 which is a specific embodiment of the shear force test fixture provided by the present utility model.

[0027] Referring to Figures 1 to 3 , the shear force test fixture includes a first fixture plate 1 and a second fixture plate 2 that fits with the first fixture plate 1. A receiving groove 11 for accommodating a metal product 3 is provided on the fitting surface of the first fixture plate 1. A welding part 31 extending outside the receiving groove 11 is provided on the metal product 3. A shear groove 21 extending towards the welding part 31 is provided along the length direction of the fitting surface of the second fixture plate 2. A push block 4 is provided in the shear groove 21. The push block 4 is slidably connected to the shear groove 21, and the push block 4 is used to connect to a pressure sensor;

[0028] A limiting groove 32 is provided on the metal product 3, a limiting block 12 extending into the limiting groove 32 is provided in the receiving groove 11, and a limiting structure 22 for abutting against the metal product 3 is provided on the fitting surface of the second jig plate 2;

[0029] A plurality of positioning posts 13 are provided on the first jig plate 1, and positioning holes 23 for the positioning posts 13 to extend into are provided on the second jig plate 2.

[0030] The shear force test of the metal product 3 can be realized through the cooperation of the first jig plate 1, the second jig plate 2 and the push block 4. The structure is simple. And through the cooperation of the limiting groove 32 and the limiting block 12, the positioning accuracy of the metal product 3 in the receiving groove 11 can be improved to ensure that the welded part 31 extends into the shearing groove 21; through the limiting effect of the limiting structure 22 on the metal product 3, the problem that the metal product 3 shakes during the test, resulting in errors in the test results, can be avoided; through the positioning effect of the positioning posts 13 and the positioning holes 23, the positioning accuracy of the first jig plate 1 and the second jig plate 2 can be improved to ensure that the shearing groove 21 corresponds to the welded part 31, thereby improving the test accuracy.

[0031] An observation port 24 corresponding to the position of the receiving groove 11 is formed on the second jig plate 2. Through the observation port 24, the operator can observe the states of the metal product 3, the welded part 31 and the push block 4 in real time, which is convenient for the operator to make adjustments and operations. The operator can observe the test process and the state of the metal product 3 before and after the test through the observation port 24, without frequently disassembling the second jig plate 2 for observation, saving operation time.

[0032] A plurality of screw holes 14 for screw installation are provided on the first jig plate 1, installation holes 25 corresponding to the positions of the screw holes 14 are provided on the second jig plate 2, and the screws pass through the installation holes 25 and are connected to the screw holes 14. The screw holes 14 and the installation holes 25 correspond to each other and are connected by screws, which can ensure the alignment accuracy of the first jig plate 1 and the second jig plate 2, thereby improving the shear force test accuracy; by connecting the first jig plate 1 and the second jig plate 2 with screws, the connection between the two jig plates can be ensured to be firm and reliable, enhancing the overall structural strength and stability. At the same time, the screw connection method is simple for installation and disassembly, simplifies the installation and disassembly process, and improves the assembly efficiency.

[0033] The end of the positioning post 13 is provided with a first guiding structure 131. Specifically, the first guiding structure 131 is a hemispherical structure. The hemispherical structure has an arc-shaped surface that can provide a guiding effect for the positioning post 13, enabling the positioning post 13 to more easily and accurately enter the positioning hole 23 during the assembly process, making the assembly between the first jig plate 1 and the second jig plate 2 simpler and more efficient.

[0034] The end of the pushing block 4 is provided with a second guiding structure 41. Specifically, the second guiding structure 41 is a right trapezoidal structure. On the one hand, the tip of the right trapezoidal structure has a smaller volume, which can reduce the obstruction of the pushing block 4 to the metal product 3 and the welding part 31, facilitating the operator to observe through the observation port 24. On the other hand, one side of the right trapezoid is an inclined surface, and the inclined surface can provide a guiding effect for the pushing block 4, making it easier for the pushing block 4 to enter the shearing groove 21, facilitating the operator's operation.

[0035] A number of first magnetic attracting members are provided on the first jig plate 1, and second magnetic attracting members magnetically connected to the first jig plate 1 are provided on the second jig plate 2 (the first magnetic attracting members and the second magnetic attracting members are not shown in the figure). The first magnetic attracting members and the second magnetic attracting members can be quickly attracted to each other, making the alignment and installation between the first jig plate 1 and the second jig plate 2 simpler and faster, thereby improving the assembly efficiency. Optionally, on the basis of setting the magnetic attracting member connection method, a screw connection method with mounting holes 25 and screw holes 14 is set. The advantage of this setting is that the magnetic attraction between the magnetic attracting members helps the preliminary alignment between the first jig plate 1 and the second jig plate 2, facilitating the installation of screws, making the operation more convenient, and adding the screw connection method can make the connection between the first jig plate 1 and the second jig plate 2 more stable.

[0036] Both the first magnetic attracting member and the second magnetic attracting member are magnets. Magnets can maintain magnetism for a long time and do not require external energy to maintain their magnetic fields, so they have a long service life. Magnets are usually made of metal alloys such as iron, nickel, and cobalt. These materials are relatively abundant and environmentally friendly, and can be recycled and reused, and the cost of magnets is low.

[0037] One end of the first jig plate 1 along its length direction is provided with a buckle (the buckle is not shown in the figure), and the other end is provided with a slot that engages with the buckle to cascade a number of first jig plates 1 in sequence. Through the cooperation of the buckle and the slot, the first jig plates 1 can be cascaded, so that the shearing force test jigs can be cascaded. At this time, by setting a longer pushing block 4, multiple shearing force tests can be completed at one time, improving the test efficiency.

[0038] The above are only alternative embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
