Description

Technical Field

[0001] The utility model relates to the technical field of integrated combined pallet devices, in particular to an integrated combined pallet for an automobile chassis. Background Art

[0002] The chassis assembly line of the final assembly workshop of an automobile factory is generally composed of multiple lifting stations, each of which lifts different chassis parts to the car body. This solution makes the chassis assembly line long, labor-intensive, and time-consuming to assemble. Although the assembly process of the chassis may be different due to its different composition, it is found through analysis that the chassis assembly modules of different compositions only differ in the number of processes, and the main assembly process is basically the same. Therefore, the realization of an integral assembly pallet becomes possible. The present invention is based on the X74 pallet, adds an X83 gear, and the wheelbase difference is 169mm. The other positioning supports remain unchanged. In view of the problems of the long distance, large number of personnel, and long assembly time of the chassis assembly line, the assembly parts required for the chassis assembly line are pre-placed on the integral assembly pallet, and are lifted and installed on the car body at one time, which greatly shortens the length of the chassis assembly line and saves manpower and material resources.

[0003] For example, an integral assembly pallet for assembling automobile chassis components with publication number CN207606473U includes a skid base, a skid support block and a bottom positioning sleeve are provided at the bottom of the skid base, upwardly extending gripper positioning pins are provided on both sides of the skid base, the gripper positioning pins are used to cooperate and position the vehicle body gripper, a plurality of universal balls are provided on the upper end surface of the skid base for supporting the pallet, end limit seats are provided at the front and rear ends of the skid base, side limit blocks are provided on both sides of the skid base, a front suspension assembly pallet is placed on the plurality of universal balls at the front of the skid base, and a rear pallet floating base plate is placed on the plurality of universal balls at the rear of the skid base.

[0004] The above-mentioned device fixes the body clamp to achieve matching positioning through the placement of positioning pins, and then assembles them one by one through the placement and distribution of other components in various positions, so that the required automobile parts are placed in the required positions. This method greatly reduces the difficulty of operation, and it is difficult to make mistakes in the installation once the position is specified. However, this method still has significant defects. Relatively speaking, this method is more time-consuming, and multiple installations and fixations greatly complicate the installation process, and continuity in installation cannot be achieved.
