[0002] Heavy vehicles are large vehicles. Compared with ordinary vehicles, heavy vehicles are larger in size. The metal plates used in heavy vehicles are also relatively thick and large. Multiple groups of metal plates are welded together to form the relevant parts of heavy vehicles. 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 vehicles, special laser welding machines are often used.

[0003] To this end, the patent specification with publication number CN118635672B discloses a laser welding machine, which includes a machine base, a frame fixedly mounted on the upper rear end of the machine base, a welding piece mounted on the front end of the frame, and protruding seats fixedly mounted on the upper parts of both sides of the frame. Positioning sleeves are elastically mounted on the ends of the protruding seats. Two arc-shaped brackets are symmetrically arranged on the front end of the upper end of the machine base. Limiting convex edges extend from the front and rear edges of the upper ends of the arc-shaped brackets. The opposite ends of the two arc-shaped brackets are connected to limiting plates. The present invention reduces the labor intensity of the staff, improves welding efficiency, ensures the normal operation of the blanking operation, and also guarantees the welding quality.

The docking assembly 4 includes a docking movable frame 401 and an adjustment structure 402. The docking movable frame 401 is fixedly connected to the top of the main frame 1. The display 301 and the camera module 308 are linearly connected. The docking movable frame 401 is internally rotatably connected to a bidirectional threaded rod. The interior of the docking movable frame 401 is fixedly connected to a guide rod. The top of the docking movable frame 401 is equipped 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 internal threaded tube 4025, a support rod 4026, a traction rod 4027, a roller 4028, a fixed rod 4029, and an internal 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. The lower part of the support frame 4021 is rotatably connected to a two-way adjustment rod 4023, one end of the two-way adjustment rod 4023 passes through the outside of the support frame 4021 and is fixedly connected to one end of the countersunk cap 4024, the outer side of the two-way adjustment rod 4023 is sleeved with an internal threaded tube 4025, the top of the internal threaded tube 4025 is hinged with a support rod 4026, the middle position of the support rod 4026 is rotatably connected to a traction rod 4027, the top of the outer side of the support rod 4026 is rotatably connected to a roller 4028, and one side of the traction rod 4027 is fixedly connected to a fixed rod 4029.One side of the fixed rod 4029 is fixedly connected to an internally threaded seat 40210, and the internal threads of the internally threaded seat 40210 are connected to an adjustment screw 40211.

[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, when welding the 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 center line. After the metal sheet structures are clamped, the docking movable frame 401 is used to make the welding positions of the two sets of metal sheet structures contact. 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 opposite directions, so that 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 fixed rod 4029 to move together. The roller 4028 supports the center 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 that a certain degree of local height adjustment can be performed 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 505, a clamping plate 506, a rack 507, a base 508, a sliding sleeve assembly 509, a gear 510, an electromagnet 511, a base 512, a paddle 513, a blocking rod 514, a traction oblique frame 515, a top seat 516, a sliding sleeve seat 517, a slide 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. Both ends of the linkage plate 503 are hinged with connecting rods 504. Slide grooves 505 are provided at both ends of the interior of the clamping frame 501. The top of the slide groove 505 is slidably connected to a clamping plate 506. 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. The middle position of the bottom end of the clamping frame 501 is fixedly connected to a base frame 508. 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 to a base 512. 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. The interior of the clamping plate 506 is penetrated by a traction oblique frame 515, and both ends of the top of the traction oblique frame 515 are slidably connected to a top seat 516. One end of the clamping plate 506 is fixedly connected to a sliding sleeve seat 517, and the inner of the sliding sleeve seat 517 is fixedly connected to the bottom end of the main frame 1. The upper portion is slidably connected to a slide rod 518, and a high-pressure spring 519 is sleeved on the lower outer side of the slide rod 518. The top of the high-pressure spring 519 is fixedly connected to the upper pressure plate 520. The connecting rod 504 and the clamping plate 506 are hinged. The electric telescopic rod 502 and the electromagnet 511 are linearly connected to 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. 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 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12When the laser welding machine is in use, the two sets of metal sheet structures to be welded are clamped on the top of the two sets 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 set of clamping plates 506, when the electric telescopic rod 502 begins to retract, the two sets of clamping plates 506 are hinged with the connecting rod 504 and the clamping plate 506, so that the two sets of clamping plates 506 slide along the slide groove 505 and clamp the two ends of the metal sheet structure. In the process of the two sets of clamping plates 506 clamping the inner metal sheet structure, the top seat 516 is pushed to move along the top inclined surface of the traction oblique frame 515, and at the same time, the metal sheet structure is lifted and the upper pressure plate 520 is pushed upward. As the clamping plate 506 is clamped, the upper pressure plate 520 is pushed upward. 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.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
