Multiple groups of metal plates are welded together to form the relevant parts of the heavy-duty vehicle. In order to improve its production efficiency, traditional metal plate welding cannot meet the production needs. Therefore, when welding the metal plate structure of heavy-duty vehicles, special laser welding machines are often used for welding.

The display 301 and the camera module 308 are linearly connected. The docking movable frame 401 is internally rotatably connected with a bidirectional threaded rod. The interior of the docking movable frame 401 is fixedly connected with a guide rod. The top of the docking movable frame 401 is installed with an adjustment structure 402. The adjustment structure 402 includes a support frame 4021, a guide groove 4022, a bidirectional adjustment rod 4023, a countersunk cap 4024, an internally threaded tube 4025, a support rod 4026, a traction rod 4027, a roller 4028, a fixed rod 4029, and an internally threaded seat 4 0210 and adjusting screw 40211, the support frame 4021 is installed on the top of the docking mobile frame 401, and guide grooves 4022 are provided on both sides of the support frame 4021.

[0039] Refer to the attached Figure 3 , Figure 5 , Figure 6 and Figure 7 Since the metal sheet structure of a heavy vehicle is relatively large in size, when welding two sets of metal sheet structures, the two sets of metal sheet structures are prone to bending to varying degrees due to gravity, which makes it impossible to effectively align the welding positions of the two sets of metal sheet structures. Therefore, support frames 4021 are installed on both sides of the top of the docking movable frame 401 near its top middle line. After the metal sheet structure is clamped, the two sets of metal sheet structure welding positions are brought into contact through the docking movable frame 401. At this time, a special wrench tool is used to rotate the countersunk cap 4024 to drive the two-way adjustment rod 4023. By controlling the forward and reverse rotation of the two-way adjustment rod 4023, the two sets of internal threaded pipes 4025 threadedly connected thereto are moved in the opposite direction and the two sets of cross The support rods 4026 of the fork are brought together, so that the roller 4028 lifts the welding end of the metal sheet structure to a certain extent. When the welding end of the metal sheet structure is wider, as the traction rod 4027 moves upward along the guide groove 4022, it will also drive the fixing rod 4029 to move together. The roller 4028 supports the central area of ​​the welding end of the metal sheet structure. At this time, the two ends of the welding point at the end of the metal sheet structure are prone to sinking and offset due to gravity. The adjusting screw 40211 can be rotated to move it upward along the internal thread of the internal thread seat 40210, so as to perform a certain degree of local height adjustment from both ends of the welding point at the end of the metal sheet structure, so that the welding end of the metal sheet structure can be aligned and welded as a whole.

[0040] The two sides of the top of the docking movable frame 401 are provided with a clamping mechanism 5, which includes a clamping frame 501, an electric telescopic rod 502, a linkage plate 503, a connecting rod 504, a slide groove 505, a clamping plate 506, a rack 507, a bottom frame 508, a sliding sleeve assembly 509, a gear 510, an electromagnet 511, a base 512, a paddle 513, a blocking rod 514, a traction inclined frame 515, a top seat 516, a sliding sleeve seat 517, a sliding rod 518, a high-pressure spring 519 and an upper pressure plate 520. The clamping frame 501 is slidably connected to the docking movable frame 40 1, an electric telescopic rod 502 is installed on one side of the bottom of the clamping frame 501, a linkage plate 503 is rotatably connected to the middle position of the top of the clamping frame 501, and both ends of the linkage plate 503 are hinged with connecting rods 504, and both ends of the inside of the clamping frame 501 are provided with sliding grooves 505, and the top of the sliding groove 505 is slidably connected to the clamping plate 506, and the bottom end of the clamping plate 506 passes through the bottom of the clamping frame 501 and is fixedly connected to the top of the rack 507, and the bottom of the clamping frame 508 is fixedly connected to the middle position of the bottom of the clamping frame 501. The bottom end is fixedly connected with a sliding sleeve assembly 509, and the other side of the bottom end of the main frame 1 is rotatably connected with a gear 510, one end of the gear 510 is provided with an electromagnet 511, and one end of the electromagnet 511 is fixedly connected with a base 512, and the top of the base 512 is rotatably connected with a paddle 513, and one side of the paddle 513 is provided with a blocking rod 514, and the interior of the clamping plate 506 is penetrated by a traction inclined frame 515, and both ends of the top of the traction inclined frame 515 are slidably connected with a top seat 516, and one end of the clamping plate 506 is fixedly connected with a sliding sleeve seat 517, and the inner The upper portion is slidably connected to a slide rod 518, a high-pressure spring 519 is sleeved below the outer side of the slide rod 518, the top of the high-pressure spring 519 is fixedly connected to an upper pressure plate 520, the connecting rod 504 and the clamping plate 506 are in a hinged structure, the electric telescopic rod 502 and the electromagnet 511 are both in a linear connection structure with the control panel 302, a torsion spring elastically connected to the base 512 is installed inside the paddle 513, and the torsion direction is toward the blocking rod 514, and the sliding sleeve assembly 509 is an internal threaded sleeve and a sliding sleeve that match the bidirectional threaded rod and guide rod inside the docking mobile frame 401.

[0041] Refer to the attached Figure 3 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12When the laser welding machine is used, the two groups of metal sheet structures to be welded are clamped on the top of the two groups of clamping frames 501 respectively. When clamping, the electric telescopic rod 502 is started through the control panel 302. Since the extended end of the electric telescopic rod 502 is fixed to the bottom end of a group of clamping plates 506, when the electric telescopic rod 502 begins to shrink, the two groups of clamping plates 506 are hinged with the connecting rod 504 to slide along the slide groove 505 and clamp the two ends of the metal sheet structure. In the process of the two groups of clamping plates 506 clamping and moving the inner metal sheet structure, the top seat 516 will be pushed to move along the top inclined surface of the traction inclined frame 515, and the metal sheet structure will be lifted and the upper pressing plate 520 will be pushed upwards while the clamping plate 506 is moving. When the metal sheet structure is clamped, the top seat 516 will also lift the metal sheet structure, and under the elastic force of the high-pressure spring 519, the upper pressure plate 520 will press and clamp the top of the metal sheet structure. At the same time, when the clamping plate 506 moves, its bottom rack 507 drives the gear 510 to rotate. At this time, the paddle 513 will fluctuate repeatedly under the action of its own torsion spring. When the clamping plate 506 is clamped, the rack 507 stops moving. At the same time, the paddle 513 will be locked with the gear 510 under the blocking of the baffle 514, so that the two sets of clamping plates 506 cannot move reversely after clamping the metal sheet structure, and become loose. When the metal sheet structure needs to be removed, one end of the electromagnet 511 needs to be retracted through the control panel 302, so that the gear 510 and the paddle 513 can contact and engage.
