These parts are interconnected and together constitute the supporting structure of the engine compartment. The design of the engine compartment side beam structure is not only related to the overall strength and stability of the vehicle, but also directly affects the safety performance of the vehicle. Through reasonable structural design, such as integrating the A-pillar reinforcement plate and the rear section of the engine compartment side beam outer panel into one piece, it is conducive to achieving the overall lightweight of the vehicle and making the collision force transmission smoother, thereby improving the collision safety of the vehicle.

When the workpiece is vibrated, the relative sliding between the protrusions and the grooves is utilized to reduce the vibration radially, so as to avoid the workpiece from shifting and affecting the repair welding effect. At the same time, the limit plate and the fixing ring are in contact with the inner wall of the bottom of the side beam. By setting the magnetic ball and the fixing ring, the inner wall of the bottom of the side beam is supported and fixed.

At the same time, the limit plate 410 and the fixing ring 46 are in contact with the inner wall of the bottom of the side beam. By setting the magnetic ball 47 and the fixing ring 46, the inner wall of the bottom of the side beam is supported and fixed. At the same time, the magnetic ball 47 has magnetism and can generate magnetic adsorption with the cross beam, so that multiple groups of magnetic balls can fix the uneven bottom of the side beam at different positions.

[0037] After the workpiece is fixed, the cylinder 6 drives the fixing block 7 to move downward, and at the same time the motor 2 is connected to an external power supply to work, the motor 2 drives the screw 8 to rotate, and the screw 8 drives the welding assembly 3 to move, so that welding can be performed at different positions on the side beam.

[0038] When the movable block 31 is located in the middle of the fixed block 7, the magnetic forces of the two side magnetic blocks on the rotating plate 34 are the same. At this time, under the mutual repulsive force between the two rotating plates 34, the rotating plate 34 is located on the side of the through hole 33 away from the middle. At this time, the two sides of the positioning block 36 are supported by the support column 35 and are located horizontally, so that the top surface of the workpiece is welded. When welding is performed on the side of the workpiece, the movable block 31 moves on the screw 8, and the rotating plate 34 on one side approaches the magnetic block, the distance between the rotating plate 34 and the magnetic block is reduced, and the mutual repulsive force between the rotating plate 34 and the magnetic block becomes larger, so that the rotating plate 34 moves in the direction away from the magnetic block inside the through hole 33. At the same time, under the mutual repulsive force between the two rotating plates 34, the positioning block 36 rotates around the positioning plate 311, so that the positioning block 36 drives the welding gun 37 to tilt, and then the side of the workpiece is welded. The inclination angle of the welding is adjusted according to the welding position, so that the appropriate inclination angle can control the molten pool shape and metal flow of the weld, which helps to improve the quality of the weld.
