[0049] The working principle of the utility model is:
[0050] When welding the chassis panel, firstly, the horizontal bars and the vertical bars on the panel frame are placed on the positioning frame 21 in sequence, and when placing, the horizontal bars or the vertical bars should be fitted on the stop bar 211, and the pressing piece 22 is lifted, so that the side bottom of the pressing piece 22 is pressed on the rod of the frame. In the process of pressing down, the first spring 222 sleeved on the guide column 221 can make the pressing piece 22 fit closely with the frame; and with the cooperation between the stop bar 211 and the pressing piece 22, the upper and side edges of the panel frame to be welded can be positioned;
[0051] Then, hold the pressing handle 35 with your hand and apply pressure downward. As the pressing handle 35 rotates downward, the pressing seat 32 is driven to move downward, and the pressing member 33 is opened outward. As the opening angle of the pressing member 33 gradually increases, the pressing claws 331 on the pressing member 33 are pressed on the inner four corners of the frame, so that the inner corners of the frame can be positioned during welding to prevent them from being misaligned during welding.
[0052] After the four corners of the panel frame are fixed by the corner limit assembly 3, the next step is to push the upper mechanism 42 downward. As the upper mechanism 42 moves, the cone 421 will move upward. The shape of the cone 421 is set to be a frustum. As the cone 421 moves upward, the cone 421 will connect with the roller 434 and push the edge slider 43 to move toward the position of the panel frame, and allow the claw 433 to be engaged with the inner side of the panel frame, so that the inner side of the frame can be further fixed to avoid displacement of the frame during welding, thereby improving the accuracy of panel welding.
[0053] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
