A number of guide posts 5 are arranged around the pneumatic push rod 6, and the guide posts 5 are fixedly connected to the movable plate 4. The top of the guide post 5 passes through the frame 1. The automobile door panel is placed in the groove 7102 of the movable seat 71. The push rod end of the electric push rod 1 2 drives the limit plate 3 and the positioning components 9 thereon to move downward. The positioning components 9 limit and fix the automobile door panel. After that, the push rod end of the pneumatic push rod 6 pushes the movable plate 4 and the welding heads 8 thereon to move downward. The welding heads 8 pass through the through holes on the limit plate 3, and the welding heads 8 contact the automobile door panel to weld the automobile door panel.

[0042] Among them, as Figure 4 shown, the positioning component 9 includes a fixed sleeve 91, a spring 92, and a positioning post 93. The fixed sleeve 91 is fixedly connected to the bottom of the limit plate 3. The spring 92 is arranged in the fixed sleeve 91. One end of the spring 92 is fixedly connected to the limit plate 3. The positioning post 93 is arranged in the fixed sleeve 91, and the positioning post 93 is fixedly connected to the other end of the spring 92. When the limit plate 4 drives the positioning component 9 to move downward close to the automobile door panel, the positioning post 93 abuts against the automobile door panel, and the spring 92 is compressed. Under the pressure of the spring 92, the automobile door panel is limited and fixed, which is convenient for subsequent welding.

[0043] Specifically, as Figure 3As shown in the figure, the workbench assembly 7 includes a movable seat 71, an electric push rod II 72, a top plate 73, a servo motor 74, a push plate 75, and a threaded rod 76. The movable seat 71 is arranged in a first groove 101 opened on the frame 1. A third groove 7102 for accommodating a car door panel is opened on the movable seat 71. The shape of the third groove 7102 is adapted to that of the car door panel. There is a cavity 7104 inside the movable seat 71. Second chutes 7103 are opened on the movable seat 71 on both sides of the third groove 7102. A second groove 7101 is opened at the top of the movable seat 71. The depth of the second groove 7101 is less than that of the third groove 7102. The top plate 73 is arranged in the third groove 7102. The shape of the top plate 73 is adapted to that of the third groove 7102. The electric push rod II 72 is fixedly installed in the cavity 7104. The push rod end of the electric push rod II 72 passes through the movable seat 71 and is fixedly connected to the top plate 73. The push plate 75 is slidably matched with the second chutes 7103. The push plate 75 is composed of a U-shaped plate and a cross plate. The U-shaped plate is arranged in the cavity 7104. The cross plate is arranged on the movable seat 71. The vertical ends on both sides of the U-shaped plate pass through the second chutes 7103 and are fixedly connected to the cross plate. The cross plate is arranged between the bottom of the second groove 7101 and the top of the third groove 7102, and the top of the cross plate is higher than the top of the third groove 7102. The servo motor 74 is fixedly installed on the movable seat 71. The threaded rod 76 is threadedly engaged with the push plate 75. The end of the threaded rod 76 is in transmission connection with the output shaft of the servo motor 74. After the welding of the car door panel is completed, the push rod end of the electric push rod II 72 pushes the top plate 73 to move upward, pushing the car door panel out of the third groove 7102. Then, the servo motor 74 drives the threaded rod 76 to rotate. According to the principle of screw transmission, the push plate 75 is driven to move close to the car door panel, pushing the car door panel out of the movable seat 71 by a certain distance, facilitating the worker to take the car door panel. Compared with the prior art, when taking the car door panel in this device, the position of the movable seat 71 remains unchanged, saving the time for the movable seat 71 to move in / out, saving time and effort, and improving work efficiency.

[0044] Specifically, as Figure 2 and Figure 3 shown in the figure, a first chute 102 connected to the first groove 101 is opened on the frame 1. Iron sliders 77 slidably matched with the first chute 102 are fixedly connected to both sides of the movable seat 71. An electromagnet 10 connected to the iron slider 77 is fixedly connected to the first chute 102. After the electromagnet 10 is energized, the slider 77 is fixed, and thus the movable seat 71 is fixed on the frame 1. After the electromagnet 10 is de-energized, the slider 77 loses its restraint, and the movable seat 71 can be removed from the first groove 101, facilitating the movable seat 71 adapted to car door panels of different shapes.

[0045] It should be noted that this device provides the required electrical energy for the electrical equipment used through an external power supply.

[0046] Working principle: When in use, different movable seats 71 are replaced according to the shape of the car door panel, so that the groove three 7102 on it matches the door panel to limit and install the door panel. After the movable seat 71 is installed in the groove one 101 through the slider 77, the electromagnet 10 is powered on. The electromagnet 10 is fixedly connected to the iron slider 77 to fix the movable seat 71 on the frame 1. Then, the car door panel is placed in the groove three 7102 of the movable seat 71. The push rod end of the electric push rod one 2 drives the limit plate 3 and the positioning component 9 on it to move downwards. The positioning component 9 limits and fixes the car door panel. Then, the push rod end of the pneumatic push rod 6 pushes the movable plate 4 and the welding head 8 on it to move downwards. The welding head 8 passes through the through hole on the limit plate 3, and the welding head 8 contacts the car door panel to weld the car door panel. After the welding of the car door panel is completed, the push rod end of the electric push rod two 72 pushes the top plate 73 to move upwards to push the car door panel out of the groove three 7102. Then, the servo motor 74 drives the threaded rod 76 to rotate. According to the principle of screw drive, the push plate 75 is driven to move close to the car door panel to push the car door panel out of the movable seat 71 by a certain distance, which is convenient for workers to take the car door panel. Compared with the prior art, when taking the car door panel, the position of the movable seat 71 remains fixed, saving the time for the movable seat 71 to move in / out, saving time and effort, and improving work efficiency.
