[0023] Specifically, the lifting and buffering device 4 includes a connecting frame 41, a motor 42, a lifting plate 43, a rotating plate 44, a buffering assembly 45 and a lead screw 46. A rotating plate 44 is installed on one side of the rotating assembly 2 close to the two support frames 8, a lifting plate 43 is installed on one side of the two support frames 8 close to the rotating plate 44, a connecting frame 41 is arranged on the outer side of the lifting plate 43, a motor 42 is installed above the connecting frame 41, a lead screw 46 is installed on one side of the motor 42 close to the connecting frame 41, and a buffering assembly 45 is installed between the connecting frame 41 and the rotating plate 44.

[0024] By adopting the above technical solutions, the device can adjust the height of structures such as the support frame 8 to a certain extent through the cooperation of structures such as the lead screw 46 and the lifting plate 43 when needed, so as to better meet the working needs in different situations.

[0025] Specifically, one side of the lifting plate 43 is in close contact with the inner side of the connecting frame 41.

[0026] By adopting the above technical solution, the device can limit and guide the movement of the lifting plate 43 through the connecting frame 41 to prevent the lifting plate 43 from rotating and shifting during the movement, thereby ensuring the normal progress of the work.

[0027] Specifically, the buffer assembly 45 includes a damper 451 and an elastic rubber frame 452. An elastic rubber frame 452 is installed between the connecting frame 41 and the rotating plate 44, and a plurality of dampers 451 are installed between the connecting frame 41 and the rotating plate 44 and at a position inside the elastic rubber frame 452.

[0028] By adopting the above technical solution, the device can buffer external vibrations through the cooperation of structures such as the damper 451 and the elastic rubber frame 452, thereby reducing the possibility of the work being adversely affected by external vibrations.

[0029] When this embodiment is in use, when it is necessary to use the device to weld the air conditioner evaporator for engineering vehicles, place the air conditioner evaporator for engineering vehicles above the fireproof sponge 5, and operate the clamping assemblies 6 on the two support frames 8 to clamp it. Then start the motor 42 in the lifting and buffering device 4 to drive the lead screw 46 to rotate. The lead screw 46 is threadedly connected to the lifting plate 43, and the lifting plate 43 is in close contact with the connecting frame 41.

During the welding work, the staff can start the rotating assembly 2 on the workbench 1 to drive structures such as the rotating plate 44 to rotate, thereby driving the air conditioner evaporator to rotate. The support assembly 3 plays a supporting role.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the temperature reduction treatment device 7 includes an electric telescopic rod 71, a partition net 72, a blower 73, an L-shaped box 74 and a spray head 75. An electric telescopic rod 71 is installed on one side of the two support frames 8 away from the lead screw 46. An L-shaped box 74 is installed on the outer side of the electric telescopic rod 71. A blower 73 is installed on one side of the L-shaped box 74 away from the two support frames 8. A plurality of spray heads 75 are installed below the top of the L-shaped box 74.

[0032] By adopting the above technical solution, the device can perform a certain temperature reduction treatment on the welded air conditioner evaporator through the cooperation of structures such as the blower 73 and the spray head 75 when needed, thereby facilitating the operation of the staff.

[0033] Specifically, the temperature reduction treatment device 7 further includes a partition net 72, and the partition net 72 is installed on the side of the air inlet end of the fan 73 far from the L-shaped box 74.

[0035] When this embodiment is in use, after welding is completed, the staff can start the electric telescopic rod 71 in the temperature reduction treatment device 7, thereby driving structures such as the L-shaped box 74 to move until each nozzle 75 moves above the air conditioner evaporator. Then start the fan 73, and the fan 73 sends the air filtered by the partition net 72 into the L-shaped box 74. Then the air is sprayed from each nozzle 75 onto the air conditioner evaporator, taking away the heat on the air conditioner evaporator, thereby performing a certain temperature reduction on the air conditioner evaporator and facilitating the staff to operate on it.

[0036] In the present utility model, the structure and principle of the workbench 1 and the structures thereon, the rotation assembly 2 composed of a rotation motor and a foot switch, the support assembly 3 composed of a support column and an adjustable bolt, the fireproof sponge 5, the clamping assembly 6 composed of a clamping electric cylinder, a clamping plate and a buffer plate, and the support frame 8 have been disclosed in a welding device for the production of vehicle air conditioner evaporators with Chinese patent application number 202022819469.1. Its working principle is to set a clamping device to fix the position of the air conditioner evaporator during manual welding, reduce the collision damage rate of the air conditioner evaporator, and improve the product qualification rate; by setting a rotation device, the rotation welding of the air conditioner evaporator during the welding of the arc surface is realized, reducing the labor intensity of the staff, improving the welding quality, and greatly increasing the product qualification rate and processing efficiency of the air conditioner evaporator.

[0037] In the present utility model, the structure and principle of the damper 451 have been disclosed in a washing machine shock absorption device for smart home appliances with Chinese patent application number 201721446985.6. Its working principle is composed of a piston and a fuel tank, and its interior is filled with hydraulic oil. When an object moves, the piston will move in the hydraulic oil, thereby consuming energy and slowing down the movement of the object.

[0038] Working principle and usage process of the present utility model: When it is necessary to use the device to weld the evaporator of the engineering vehicle air conditioner, place the evaporator of the engineering vehicle air conditioner above the fireproof sponge 5, and operate the clamping components 6 on the two support frames 8 to clamp it. Then start the motor 42 in the lifting and buffering device 4, which drives the screw rod 46 to rotate. The screw rod 46 is threadedly connected to the lifting plate 43, and the lifting plate 43 is in close contact with the connecting frame 41. Therefore, the screw rod 46 drives the lifting plate 43 to move, thereby adjusting the height of the two support frames 8 and other structures. The damper 451 and the elastic rubber frame 452 in the buffering component 45 can buffer the external vibration. Then operate the welding equipment to weld the air conditioner evaporator. During the welding operation, the staff can start the rotating component 2 on the workbench 1 to drive the rotating plate 44 and other structures to rotate, thereby driving the air conditioner evaporator to rotate. The supporting component 3 plays a supporting role; after welding is completed, the staff can start the electric telescopic rod 71 in the temperature reduction treatment device 7, which drives the L-shaped box 74 and other structures to move until each nozzle 75 moves above the air conditioner evaporator. Start the fan 73, and the fan 73 sends the air filtered by the partition net 72 into the L-shaped box 74. Then the air is sprayed from each nozzle 75 onto the air conditioner evaporator, taking away the heat on the air conditioner evaporator, thereby performing a certain temperature reduction on the air conditioner evaporator, which facilitates the staff to operate it.
