[0002] With the continuous development of automobile welding technology, laser welding has become a conventional welding process in welding workshops.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It is obvious that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be understood that the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, it can also be a detachable connection, or it can be connected in one piece: it can be directly connected, it can also be indirectly connected through an intermediate medium, and it can be the communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0028] A small test welding platform will be set up at the laser welding station for debugging before welding. The design of the test welding platform will follow the actual overlap state of the welded parts, so that the placement state of the test welding piece is as consistent as possible with the state of the two welded plates during actual welding. The production line will have production requirements for multiple models, and the overlap angles of the welded plates of different models will be different.

[0029] In response to the above technical issues, such as Figure 1a As shown, the utility model provides a multi-angle laser melting welding test welding platform, which can include a base 1, a support block 2 and a fixing mechanism 3. The base 1 has a mounting surface 11, and the mounting surface 11 is used to place a lower test welding piece 100. The support block 2 is installed on the mounting surface 11, and the support block 2 has a support surface 21 inclined in the direction toward the lower test welding piece 100, and the support surface 21 is used to support the upper test welding piece 200, and one end of the upper test welding piece 200 is abutted against the upper end surface of the lower test welding piece 100, so that an angle is formed between the lower test welding piece 100 and the upper test welding piece 200. The fixing mechanism 3 is installed on the base 1, and the fixing mechanism 3 moves relative to the base 1 to press the upper test welding piece 200, thereby fixing the relative position of the upper test welding piece 200 and the lower test welding piece 100. One end side of the upper test welding piece 200 is placed on the supporting surface 21 and fits with the supporting surface 21, and the other end of the upper test welding piece 200 is overlapped on the lower test welding piece 100. Laser melting welding test welding is performed at the position where the upper test welding piece 200 contacts the lower test welding piece 100.

[0030] A test welding platform will be set up at the laser welding station for debugging before welding. The lower test welding piece 100 is placed on the mounting surface 11, and one end of the upper test welding piece 200 is overlapped on the lower test welding piece 100. The side of the other end of the upper test welding piece 200 is attached to the support surface 21. In this way, a desired angle is formed between the upper test welding piece 200 and the lower test welding piece 100, and the relative positions of the lower test welding piece 100 and the upper test welding piece 200 are fixed by the fixing mechanism 3. The angle between the upper test welding piece 200 and the lower test welding piece 100 can be adjusted by replacing the support block 2 with a different degree of inclination of the support surface 21.

[0031] In order to facilitate the fixation of the upper test welding piece 200, as Figure 1b , Figure 1c and Figure 1d As shown, the support surface 21 has a recessed portion 210, and one end side surface of the upper test welding piece 200 is in contact with the inner bottom surface of the recessed portion 210, so that the upper test welding piece 200 is confined in the recessed portion 210, thereby stabilizing the relative position of the upper test welding piece 200.

[0032] In some embodiments, in order to fix the relative position of the upper test soldering sheet 200 and the lower test soldering sheet 100, as shown in FIG. Figure 2 As shown, the fixing mechanism 3 may include a clamp 31 and a pressing arm 32. The clamp 31 has a mounting portion 310 and a pressing portion 320, and the mounting portion 310 is mounted on the base 1. The pressing arm 32 is mounted on the pressing portion 320, and the pressing portion 320 rotates to drive the pressing arm 32 to move away from or close to the upper test welding piece 200. By holding the handle of the clamp 31, the pressing portion 320 rotates relative to the mounting portion 310 to move close to or away from the mounting surface 11. Since the pressing arm 32 is connected to the pressing portion 320, when the pressing arm 32 moves close to the upper test welding piece 200 to press against the upper test welding piece 200, the relative position of the upper test welding piece 200 and the lower test welding piece 100 is fixed.

[0033] In some embodiments, in order to further fix or compress the upper test welding sheet 200, as shown in FIG. Figure 2 As shown, the fixing mechanism 3 may further include a gasket 37. The gasket 37 is installed at the connection between the pressing arm 32 and the pressing portion 320 to adjust the distance between the pressing arm 32 and the pressing portion 320. By adding gaskets 37 of different thicknesses or different numbers, the fixing and pressing of the upper test welding sheet 200 can be improved.

[0034] In some embodiments, in order to further stabilize the relative position of the upper test soldering sheet 200 and the lower test soldering sheet 100, as shown in FIG. Figure 3 As shown, the fixing mechanism 3 also includes a pressing block 33. The pressing block 33 is installed on the end surface of the pressing arm 32 facing the upper test welding sheet 200, as shown in FIG. Figure 4As shown, the end surface of the pressure block 33 away from the pressure arm 32 has at least one boss 330 extending toward the upper test welding piece 200, and the end surface of the boss 330 is an arc surface. Since the end surface of the boss 330 is an arc surface, it is in line contact with the upper test welding piece 200, which is beneficial to the switching of different angles between the upper test welding piece 200 and the lower test welding piece 100, thereby improving the matching degree and stability.

[0035] In some embodiments, Figure 4 As shown, the mounting surface 11 has a groove 110 extending along the length direction of the upper test welding piece 200. The groove 110 is located below the abutment between the upper test welding piece 200 and the lower test welding piece 100 to facilitate heat dissipation during test welding.

[0036] In some embodiments, Figure 3 and Figure 4 as well as Figure 5 As shown, a multi-angle laser melting welding test welding platform also includes two limit parts 300, which are relatively installed on the mounting surface 11, and a conveying channel 310 is formed between the opposite ends of the two limit parts 300 and the mounting surface 11. The lower test welding piece 100 is placed on the mounting surface 11 through the conveying channel 310, and the end of the upper test welding piece 200 away from the support block 2 is abutted against the side of the two limit parts 300 facing the upper test welding piece 200.

[0037] In some embodiments, Figure 6 As shown, the base 1 may include a support plate 111 , and the mounting surface 11 is a surface where the support plate 111 contacts the lower soldering test piece 100 .

[0038] In some embodiments, Figure 6 As shown, the base 1 may further include a bottom plate 112 and a support 113. The support plate 111 is mounted on the bottom plate 112, and the mounting portion 310 is mounted on the surface where the bottom plate 112 contacts the support plate 111. The support 113 is mounted on the bottom plate 112, and the support 113 is mounted at the bottom of the bottom plate 112 to support the bottom plate 112.

[0039] In some embodiments, Figure 7 As shown, a multi-angle laser welding test welding platform can also include a laser power meter 4 and a laser welding head spot calibration plate 5. The laser power meter 4 is installed on the bottom plate 112. The laser welding head spot calibration plate 5 is installed on the bottom plate 112.

[0040] In some embodiments, Figure 7 As shown, a multi-angle laser fusion welding trial welding platform can also include a TCP calibration component 6, and the TCP calibration component 6 is installed on the base plate 112.

[0041] Based on the above foundation, the laser power is adjusted by using the laser power meter 4 and the position of the laser spot is adjusted by using the TCP calibration component 6, and then the test welding piece is tested for welding.

[0042] In summary, the present invention adjusts the angle between the upper test welding sheet 200 and the lower test welding sheet 100 by replacing different support blocks 2. Different support blocks 2 are support surfaces 21 with different inclinations, so as to change the inclination of the upper test welding sheet 200 overlapped on the support surface 21. Figure 8 As shown, when the upper test welding sheet 200 and the lower test welding sheet 100 need to be completely fitted, that is, the upper test welding sheet 200 is laid flat on the lower test welding sheet 100, the support block 2 is removed to enable the upper test welding sheet 200 to be directly placed on the lower test welding sheet 100. In this way, there is a gap between the upper test welding sheet 200 and the lower test welding sheet 100. By increasing the number or thickness of the gaskets 37, the pressure arm 32 can completely press the upper test welding sheet 200 onto the lower test welding sheet 100.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
