[0024] The N360PPL model belongs to a non-load-bearing body, which is different from the load-bearing bodies of existing mass-produced models. The large change in body size results in the need for the cargo box to be assembled after the production line, that is, off-line assembly. Therefore, only the cab and the frame are assembled on the production line, which causes the center of gravity of this model to move forward. When the interior transfer chassis transfer system picks up the vehicle, the body may roll over and fall, posing a great safety risk to the production line equipment and the surrounding operators.

[0025] To solve the above problems, please refer to Figures 1 to 3 As shown, the present utility model provides an automotive transfer counterweight block, which is applied to the counterweight of the rear chassis during automotive manufacturing transfer. It includes a counterweight block main body. The counterweight block main body has a length direction. Positioning holes 11 are provided at both ends of the length direction of the counterweight block. The counterweight block main body is connected to the rear chassis through the positioning holes 11. Two lifting members 4 are provided on the counterweight block main body. The two lifting members 4 are arranged oppositely. The lifting members 4 are used to lift and install the counterweight block main body on the automotive body.

[0026] Among them, the counterweight block body is made of materials such as cast iron, steel, lead and tungsten alloy. In this embodiment, the counterweight block body is made of steel, which is easy to process and can be cut and adjusted according to needs; and the positioning hole 11 corresponds to the two original positioning pins of the automobile body. After the counterweight block body is lifted by the lifting part 4 by manual lifting or mechanical lifting, the positioning hole 11 of the counterweight block body cooperates with the positioning pins, so that the counterweight block body is accurately installed on the automobile body, with the characteristics of fast positioning and good reliability; further, in this embodiment, the total weight of the counterweight block body is 40kg, so that the rear and front of the car are balanced during the transfer of the car chassis.
