[0033] Combine the following Figure 1-Figure 5 The technical solution provided by the utility model is described in more detail.

[0034] like Figure 1-Figure 3 , Figure 5As shown, the laser welding test piece folding processing device provided by the utility model comprises a fixed base 3, a first die base 1, a second die base 2, an operating rod 4, a first pressing part (a first pressing rod 5), and a second pressing part (a second pressing rod 6), wherein: the first pressing part and the second pressing part are rotatably connected to the fixed base 3, the operating rod 4 is fixedly connected to the first pressing part, and the first pressing part and the second pressing part are transmission-connected; there is a positioning groove 9 between the first die base 1 and the second die base 2, one side of the two test pieces 10 can be inserted into the positioning groove 9, and the other sides of the two test pieces 10 can be respectively located between the first pressing part and the first die base 1, and between the second pressing part and the second die base 2; the operating rod 4 can drive the first pressing part and the second pressing part to rotate in the opposite direction under the push of an external force, thereby pressing and folding the two test pieces 10 respectively.

[0035] See also Figure 4 As shown, one of the test pieces 10 simulates the side of the car, and the other test piece 10 simulates the roof of the car. After the test pieces 10 are bent and formed, the connection positions of the two test pieces 10 are welded to determine whether the quality of the weld meets the mass production requirements, thereby improving the efficiency of the laser test welding verification process.

[0036] The laser welding test piece folding processing device of this embodiment pushes the operating rod 4, and the operating rod 4 can drive the first pressing part and the second pressing part to rotate in opposite directions under the push of external force. The first pressing part and the second pressing part respectively apply downward pressure to the two test pieces 10, and the test pieces 10 gradually bend and deform until the welding test piece 10 reaches the required folding angle, thereby simulating the shape of the vehicle body roof and the vehicle body side.

[0037] The device can fold two test pieces 10 into shape at one time, so that the formed test pieces 10 can be combined and reserve welding gaps of the same shape to simulate the mass production processing state, and then control the laser welding test pieces 10 through the program to determine whether the quality of the weld meets the mass production processing requirements, thereby improving the efficiency of the laser test welding verification process.

[0038] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the first mold base 1 and the second mold base 2 are both fixed to the upper part of the fixing base 3. A storage box 31 is provided on the fixing base 3 for convenient storage.

[0039] Specifically, the first mold base 1 and the fixing base 3 are detachably connected, so that the test piece 10 can be inserted into the positioning groove 9 and the test piece 10 can be taken out easily.

[0040] Specifically, the first die base 1 and the fixed base 3 can be detachably connected by means of a locking member such as a screw, or a rotatable pin body is provided on the fixed base 3 to abut against the side of the first die base 1 away from the second die base 2, thereby preventing the first die set from being separated from the fixed base 3. When the test is completed, the first die base 1 can be removed by rotating the pin body. A handle portion is provided on the side of the second die base 2 away from the first die base 1 to facilitate the disassembly and assembly of the first die base 1.

[0041] As an alternative embodiment, see Figure 1-Figure 3 and Figure 5 As shown, the laser welding specimen folding processing device also includes a driving gear 7 and a transmission gear 8, wherein: the driving gear 7 and the transmission gear 8 are both rotatably connected to the fixed seat 3, and the driving gear 7 is fixedly connected to the operating rod 4 and the first pressing part (first pressing rod 5); the transmission gear 8 is meshed with the driving gear 7, and the transmission gear 8 is fixedly connected to the second pressing part (second pressing rod 6), and when the operating rod 4 is pushed, the driving gear 7 can drive the transmission gear 8 to rotate synchronously.

[0042] The above structure can realize synchronous reverse rotation of the first pressing part (first pressing rod 5) and the second pressing part (second pressing rod 6) when the operating rod 4 is pushed, thereby pressing two test pieces 10 at the same time, and the structure is simple.

[0043] As an optional embodiment, the first pressing part includes a first pressing rod 5, and the driving gear 7 is fixedly connected to the end of the first pressing rod 5. The second pressing part includes a second pressing rod 6 and a mounting plate 61, the mounting plate 61 is fixed to the end of the second pressing rod 6, and the transmission gear 8 is fixedly connected to the mounting plate 61.

[0044] See also Figure 2 and Figure 3 As shown, the bottom sides of the two test pieces 10 are inserted into the positioning grooves 9 and fit together, and the upper sides of the two test pieces 10 are respectively located between the first pressing part and the first die base 1, and between the second pressing part and the second die base 2. Since the operating rod 4 is fixedly connected to the first pressing part rod, the driving gear 7 and the transmission gear 8 are meshed, and the second pressing rod 6 is fixedly connected to the transmission gear 8, when the operating rod 4 is pushed, the driving gear 7 rotates with the operating rod 4, and at the same time drives the transmission gear 8 and the second pressing rod 6 fixed to the transmission gear 8 to rotate, and the rotation directions of the first pressing rod 5 and the second pressing rod 6 are opposite, so that the first pressing rod 5 and the second pressing rod 6 fold the two test pieces 10 at the same time, thereby improving the efficiency of folding and forming.

[0045] As an alternative embodiment, see Figure 1-Figure 3 As shown, the operating rod 4 is a U-shaped structure, and two sides of the U-shaped structure are fixedly connected to the opposite ends of the first pressing rod 5 respectively.

[0046] The above structure improves the stability of the connection structure between the operating rod 4 and the first pressing rod 5 , and facilitates the stable rotation of the first pressing rod 5 driven by the operating rod 4 .

[0047] As an alternative embodiment, see Figure 3 and Figure 5 As shown, the positioning groove 9 is inclined relative to the horizontal plane to facilitate the insertion of two test pieces 10.

[0048] As an alternative embodiment, see Figure 5 As shown, the driving gear 7 and the transmission gear 8 are located in the same plane. When the mounting plate 61 moves to the inner side of the driving gear 7, the side of the second pressing rod 6 facing the second mold base 2 is an inclined surface 62, so that one of the test pieces 10 can be inserted between the second pressing portion and the second mold base 2 along the inclined surface 62.

[0049] With the above structure, when the test piece 10 is inserted into the positioning groove 9 and the mounting plate 61 can be moved to the inner side of the driving gear 7, the first pressing rod 5 and the second pressing rod 6 are made more compact, and more sufficient insertion space is reserved between the second pressing rod 6 and the second mold base 2, and between the first pressing rod 5 and the first mold base 1, so as to facilitate the insertion of the test piece 10 into the positioning groove 9.

[0050] See also Figure 1-Figure 5 As shown, the laser welding test piece folding processing device of this embodiment is used. When in use, the second die base 2 is installed, and the two test pieces 10 are inserted into the positioning groove 9. The upper sides of the two test pieces 10 are respectively located between the first pressing part and the first die base 1, and between the second pressing part and the second die base 2. The operating rod 4 is pushed, and the operating rod 4 drives the driving gear 7 to rotate, and the transmission gear 8 rotates synchronously. The first pressing part and the second pressing part rotate synchronously in opposite directions, and the two test pieces 10 are pressed down respectively, so that the two test pieces 10 are folded synchronously, and the two test pieces 10 are laser welded by using the welding equipment. See FIG. Figure 4 As shown, a laser weld 11 is formed between the two test pieces 10, and it is judged whether the quality of the laser weld 11 meets the mass production processing requirements, thereby improving the efficiency of the laser test welding verification process.
