[0002] In order to verify the strength of the material after welding, in addition to shear tensile testing, a cross tensile test will also be carried out. At this time, the specimen needs to be cross-welded. The conventional operation method is to cross the specimens by hand and then weld them, but this method has low working efficiency and the specimens cannot be guaranteed to be perpendicular to each other when crossed. In related structures, a cross welding fixture is also used for auxiliary welding. The cross welding fixture has two mutually perpendicular and connected accommodating grooves, each of which is used to place a specimen. In this way, although the two specimens can be guaranteed to be perpendicular to each other, this cross welding fixture is only suitable for specimens of a certain fixed width and has poor applicability.

[0024] Please refer to Figures 1 to 2, this application provides a cross welding fixture 100. The cross welding fixture 100 includes a bracket main body 10. The bracket main body 10 has two accommodating grooves 11 that are perpendicular to each other and communicate with each other. Each accommodating groove 11 is used to place a specimen 200 so that the two specimens 200 are perpendicular to each other at the communicating part of the two accommodating grooves 11. Each accommodating groove 11 is provided with two limiting members 20 that are oppositely arranged along the width direction of the accommodating groove 11. The two limiting members 20 are used to clamp the specimen 200, and the distance between the two limiting members 20 along the width direction of the accommodating groove 11 is configured to be adjustable. In this way, by providing two accommodating grooves 11 that are perpendicular to each other and communicate with each other on the bracket main body 10, the specimens 200 placed in the two accommodating grooves 11 can be kept perpendicular to each other. Moreover, in each accommodating groove 11, by increasing or decreasing the distance between the two limiting members 20 along the width direction of the accommodating groove 11, the two limiting members 20 can cooperate to clamp specimens 200 with different widths. That is to say, the cross welding fixture 100 provided by this application can not only ensure that the specimens 200 are perpendicular to each other, but also be applicable to specimens 200 with different widths.
[0025] Optionally, in one embodiment, as Figure 1 shown, in each accommodating groove 11, the two limiting members 20 are respectively located on both sides of the other accommodating groove 11. In this way, both ends of the specimen 200 along the length direction can be subjected to the acting forces of the two limiting members 20, which is beneficial for the two limiting members 20 to clamp the specimen 200 more firmly.
[0026] Or, in another embodiment, it can also be that in each accommodating groove 11, the two limiting members 20 are respectively located on the same side of the other accommodating groove 11.
[0027] Optionally, in one embodiment, the two limiting members 20 are respectively movably connected to the side walls of the accommodating groove 11 along the width direction of the accommodating groove 11. That is to say, both of the two limiting members 20 can move along the width direction of the accommodating groove 11, which is convenient for adjusting the distance between the two limiting members 20 along the width direction of the accommodating groove 11.
[0028] Or, in another embodiment, it can also be that in each accommodating groove 11, one of the limiting members 20 is fixedly connected to the side wall of the accommodating groove 11, and the other limiting member 20 is movably connected to the side wall of the accommodating groove 11 along the width direction of the accommodating groove 11. In this way, by moving the limiting member 20 that is movably connected to the side wall of the accommodating groove 11 along the width direction of the accommodating groove 11, the distance between the two limiting members 20 along the width direction of the accommodating groove 11 can also be adjusted.
[0029] Below, taking the two limiting members 20 being respectively movably connected to the side walls of the accommodating groove 11 along the width direction of the accommodating groove 11 as an example, the specific structure of the connection between the limiting member 20 and the accommodating groove 11 and the moving process of the limiting member 20 will be introduced.
[0030] As shown Figure 2 in the figure, the limiting member 20 includes a plate body 21 and a connecting member 22. The plate body 21 is used to abut against the specimen 200, and the plate body 21 is movably connected to the side wall of the accommodating groove 11 through the connecting member 22.
[0031] Optionally, in one embodiment, the connecting member 22 is configured as a stud 221. A threaded hole 111 is provided in the side wall of the accommodating groove 11 corresponding to the stud 221. One end of the stud 221 abuts against the side surface of the plate body 21 facing away from the specimen 200, and the other end passes through and is threadedly connected to the threaded hole 111. In this way, by screwing the stud 221, the length of the stud 221 extending into the accommodating groove 11 can be adjusted, so as to adjust the position of the plate body 21 in the accommodating groove 11 along the width direction of the accommodating groove 11. Specifically, the specimen 200 can be first placed in the corresponding accommodating groove 11, and then the stud 221 is screwed, so that the length of the stud 221 extending into the accommodating groove 11 gradually increases, and the end of the stud 221 abuts against the plate body 21 and pushes the plate body 21 to abut against the specimen 200 until the two opposite plate bodies 21 clamp the specimen 200.
[0032] Furthermore, the limiting member 20 further includes a screwing portion 23. The screwing portion 23 is fixedly sleeved on the outer periphery of the stud 221 and is located outside the accommodating groove 11; by screwing the screwing portion 23, the stud 221 can be axially moved along the threaded hole 111. By providing the screwing portion 23, it is convenient for the user to screw the stud 221. Optionally, the cross section of the screwing portion 23 is a regular hexagon. In this way, the screwing portion 23 can be screwed by a hexagon wrench. Alternatively, the cross section of the screwing portion 23 can also be set to a quadrilateral, a pentagon, etc., as long as it is convenient to cooperate with the screwing tool.
[0033] In another embodiment, the connecting member 22 can also be configured as a telescopic rod that can expand and contract along the width direction of the accommodating groove 11.
[0034] Please continue to refer to Figure 2 , end plates 112 are respectively provided at both ends of the accommodating groove 11 along the length direction, and the end plates 112 extend along the width direction of the accommodating groove 11. The plate body 21 abuts against the end plates 112 and can move along the end plates 112. It can be understood that the end plates 112 can play a guiding role in the movement of the plate body 21, so that the plate body 21 can move more smoothly along the width direction of the accommodating groove 11.
[0035] Please refer to Figure 1 , the support body 10 is provided with a through hole 12 at the communication part of the two accommodating grooves 11. In this way, it is convenient for the operator to perform welding operations, such as spot welding operations, on the two specimens 200 perpendicular to each other from the upper and lower sides of the support body 10 at the through hole 12.
[0036] The lengths, widths, and heights of the two receiving grooves 11 are respectively equal, and the through holes 12 are opened at the central positions of the receiving grooves 11. In this way, it can be ensured that the two specimens 200 located in the two receiving grooves 11 are vertically welded at the center.
[0037] Exemplarily, in one embodiment, as Figure 1 and Figure 2 shown, the lengths X of the two receiving grooves 11 are respectively 180 mm, the heights Y are 12 mm, and the widths Z are 60 mm. The length of the plate body 21 is 60 mm, the thickness is 3 mm, the height is 12 mm, and the diameter of the stud 221 is 8 mm.
[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0039] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
