[0027] As a technical optimization solution of the present invention, a guide rod 29 is installed inside the mounting hole 27.

[0030] As a technical optimization solution of the present invention, through holes 9 are opened on both sides of the machine shell 2, and a plurality of flexible rubber plates 10 are installed on the inner top of the through holes 9. The two through holes 9 are respectively located on both sides below the top plate 12; the flexible rubber plates 10 are transparent, which is convenient for the staff to understand the welding process of the vehicle chassis through the flexible rubber plates 10 on both sides of the machine shell 2. At the same time, the flexible rubber plates 10 can isolate the smell generated during the welding of the vehicle chassis to a certain extent, protect the staff, and at the same time facilitate the staff to adjust the position of the vehicle chassis inside the machine shell 2 through the through holes 9.

[0031] As a technical optimization solution of the present invention, a convex exhaust machine 16 is installed on the side of the rotating plate 5 away from the inside of the machine shell 2. The exhaust machine 16 is located on the side of the second fixing hole 15, and one end of the exhaust machine 16 is located inside the second fixing hole 15. The rubber gaskets 17 on the inner walls of both sides of the second fixing hole 15 are both located on the side of the exhaust machine 16 and abut against each other; when the first fixing hole 14 clamps and fixes the vehicle chassis, the staff installs the exhaust machine 16 inside the second fixing hole 15. When the second fixing hole 15 fixes the position of the vehicle chassis, the exhaust machine 16 is installed inside the first fixing hole 14. The rubber gaskets 17 on the inner walls of both sides of the first fixing hole 14 and the second fixing hole 15 can not only protect the vehicle chassis when clamping and fixing the vehicle chassis, but also clamp and fix the exhaust machine 16 through its own elasticity.

[0032] As a technical optimization solution of the present invention, a plurality of scanners 23 are inclinedly installed on the inner walls of both ends of the machine shell 2. The scanners 23 are located above the feeding hole 3, and a plurality of scanners 23 on the inner walls of both ends of the machine shell 2 are respectively located on both sides of the top plate 12. Support columns 6 are installed at the positions close to the corners at the bottom of the base 1; the scanners 23 cooperate with a plurality of laser welding heads 26 during use, can scan the welding positions of the laser welding heads 26, and facilitate the staff to adjust the positions of the laser welding heads 26 in real time.

[0033] When the present invention is in use, the staff pulls the top end of the rotating plate 5 away from the inside of the casing 2 through the first hydraulic cylinders 7 located at both ends of the base 1, so that the top end of the rotating plate 5 is greatly inclined away from the casing 2, facilitating the staff to place and convey the vehicle chassis through the rotating plate 5. The staff places the workpiece to be welded at the designated position on the vehicle chassis in advance, and pre-fixes the vehicle chassis and the welded workpiece through spot welding to prevent the welded workpiece from falling during the installation and welding of the vehicle chassis, and improve the stability of the vehicle chassis and the welded workpiece during welding.

[0034] The staff places the vehicle chassis on one side of the rotating plate 5 away from the first hydraulic cylinder 7, so that the bottom of the vehicle chassis abuts against a plurality of rollers 20 on the side surface of the rotating plate 5, and the staff can then push the vehicle chassis into the inside of the casing 2 until the entire vehicle chassis enters the inside of the casing 2. At the same time, both ends of the vehicle chassis are respectively located on one side of the two rotating plates 5 close to the casing 2, so that the two rotating plates 5 can support the vehicle chassis and protect both ends.

[0035] The first hydraulic cylinders 7 push the two rotating plates 5 to rotate, so that the top ends of the rotating plates 5 rotate towards the inside of the casing 2. At the same time, the electric slider 22 can drive the bottom ends of the rotating plates 5 to move towards the inside of the casing 2 through the support rods 18. In use, the electric slider 22 and the first hydraulic cylinders 7 cooperate with each other to facilitate the two rotating plates 5 to better clamp and fix the vehicle chassis during use.

[0036] While the rotating plates 5 are moving and rotating, both ends of the vehicle chassis slide on the opposite surfaces of the two rotating plates 5 through a plurality of rollers 20 respectively until both ends of the vehicle chassis are inserted into the first fixing holes 14 on the side surfaces of the two rotating plates 5. In use, when both ends of the vehicle chassis are wider and the fixing positions are at the corner positions of both ends of the vehicle chassis, both ends of the vehicle chassis can slide into the first fixing holes 14. When both ends of the vehicle chassis are narrower and the fixing positions are at the middle positions of both ends of the vehicle chassis, both ends of the vehicle chassis can slide into the second fixing holes 15 on the two rotating plates 5. It can be used for fixing vehicle chassis of various different models during use.

[0037] After the two ends of the vehicle chassis are respectively moved into the first fixing holes 14 on the two rotating plates 5, the staff can pull down the top end of the rotating plate 5 by the first hydraulic cylinder 7. At the same time, the electric slider 22 drives the bottom end of the rotating plate 5 to move towards the inside of the machine housing 2, so that the connecting block 11 moves a short distance towards the inside of the machine housing 2 while moving downwards, preventing the two ends of the vehicle chassis from moving out of the first fixing holes 14 when the first hydraulic cylinder 7 pulls down the top end of the rotating plate 5. The electric slider 22 drives the movement of the rotating plate 5 to clamp the vehicle chassis by the two rotating plates 5. At the same time, when the first hydraulic cylinder 7 drives the top end of the rotating plate 5 to move downwards, the first fixing holes 14 on the side surface of the top end of the rotating plate 5 are inclined, and the vehicle chassis is clamped and fixed by the inner walls on both sides of the inclined first fixing holes 14. At the same time, rubber bushings 17 are installed on the inner walls on both sides of the first fixing holes 14 and the second fixing holes 15, which can play a good role in protecting the surface of the vehicle chassis when clamping the vehicle chassis, preventing the surface of the vehicle chassis from being indented due to excessive clamping force.

[0038] When installing and fixing the vehicle chassis, the staff can understand the position of the vehicle chassis in real time through the through holes 9 on both sides of the machine housing 2, which is convenient for the staff to adjust the position of the vehicle chassis at any time, so that the two rotating plates 5 can better clamp and fix the vehicle chassis. After the staff finishes installing and fixing the vehicle chassis, the staff inserts one end of the exhaust machine 16 into the second fixing hole 15, and the rubber bushings 17 on the inner walls on both sides of the second fixing hole 15 clamp the exhaust machine 16 through their own elasticity. The end of the exhaust machine 16 far away from the machine housing 2 is connected to the external air duct. When in use, the exhaust machine 16 can discharge the harmful gases generated during the welding of the vehicle chassis to a designated position or container, preventing the harmful gases from harming the bodies of the staff around the machine housing 2.

[0039] During use, the operator can drive the rotating shaft 13 and the top plate 12 to rotate through the motor 8, and adjust the positions of a number of laser welding heads 26 at the bottom of the top plate 12. After the operator finishes adjusting the positions of the laser welding heads 26 through the motor 8, the electric slide 31 can drive the laser welding heads 26 at its bottom to slide on the outer wall of the guide rod 29. During use, the positions of the laser welding heads 26 and the electric slide 31 on the guide rod 29 can be adjusted. At the same time, when the electric slide 31 moves, the mounting holes 27 can play a good role in protecting and guiding both sides of the electric slide 31. The operator pushes the block 28 downward through the second hydraulic cylinder 25, and makes the guide rod 29 rotate around the fixed rod 32 through the block 28. When the fixed rod 32 rotates, it can drive the electric slide 31 and the laser welding heads 26 to move downward and rotate until the bottom end of the laser welding head 26 rotates above the welding position of the top of the vehicle chassis and the workpiece to be welded, and then the laser welding head 26 can weld the vehicle chassis. During use, a number of laser welding heads 26 are installed at the bottom of the electric slides 31, and the laser welding heads 26 can be installed obliquely or vertically at the bottom of the electric slides 31, which is convenient for welding the gaps on the surface of the vehicle chassis at different angles during use. During use, the laser welding head 26 uses a laser beam with a high energy density as a heat source to heat the connection gap between the vehicle chassis and the workpiece, melting and connecting the positions of the vehicle chassis and the workpiece near the connection end, achieving the effect of welding the vehicle chassis and the workpiece to each other. Good welding effects can be achieved in the production of vehicle chassis of different models of new energy vehicles, improving the production efficiency of the new energy vehicle chassis, and there is no need for the operator to manually weld the vehicle chassis and the workpiece to be welded, which is convenient for the intelligent manufacturing production and use of the vehicle chassis.

[0040] During the welding of the vehicle chassis, the scanners 23 on the inner walls at both ends of the casing 2 can scan the welding position in real time, understand the accuracy of the welding position and the welding effect, and facilitate the operator to adjust the position of the laser welding head 26 through the cooperation of the motor 8, the second hydraulic cylinder 25 and the electric slide 31. After the vehicle chassis is welded, the electric slider 22 can drive the bottom end of the rotating plate 5 to move away from the inside of the casing 2, and at the same time, the first hydraulic cylinder 7 pushes the top end of the rotating plate 5 upward until both ends of the vehicle chassis are removed from the inside of the first fixing holes 14 on the two rotating plates 5, and the surfaces of both ends of the vehicle chassis are respectively abutted against a number of rollers 20 on the opposite surfaces of the two rotating plates 5. After both ends of the vehicle chassis are removed from the inside of the first fixing holes 14, the first hydraulic cylinder 7 pulls down the top end of the rotating plate 5, making the top end of the rotating plate 5 tilt again significantly away from the casing 2, and then the operator can pull one end of the vehicle chassis, and the vehicle chassis can be removed from the casing 2 through a number of rollers 20 on the rotating plate 5.

[0041] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
