Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly, in particular to an assembly trolley for an automobile final assembly production line. Background Art

[0002] The layout of the automobile assembly line is generally that automobile parts are distributed to each workstation line through logistics, and standard parts (bolts, screws, clips, etc.) are centrally distributed to a designated area next to the production line. Generally, there is one standard parts area for each work section. Operators put the standard parts into the material box according to assembly requirements, take them to the assembly station and place them on the material rack next to the workstation line.

[0003] Each operator in the chassis area of ​​the automobile assembly line generally has two tools. He takes the first tool and walks to the assembly position under the car. After completing the work, he walks back to the line and places it in the material box. Then he takes the second tool and repeats the above operation until the work of one station is completed. Taking tools generates 4 walking hours, and special stations with 3 tools generate 6 walking hours. Since operators need to walk from the assembly position to the tool placement box to take and replace assembly tools, this process leads to an increase in HPV (single vehicle working hours), an increase in the demand for operators, and the final result is an increase in production costs. In addition, the weight of automobile chassis parts is relatively heavy, and the number of fastening bolts / nuts is large. Operators take them with one hand (one hand for tools, one hand for parts / standard parts). Similar to taking tools, operators take parts from the assembly position to the line side, which generates multiple walking and variable working hours, and the labor load of personnel increases. Therefore, it is necessary to invent a trolley for assembly of automobile assembly production lines. Utility Model Content

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A trolley for assembling an automobile assembly line comprises a body with universal wheels, a plurality of tool support plates are arranged on the body, a plurality of tool butts are arranged on one side of the body, and a plurality of tool hooks are arranged on the other side of the body.

[0007] Furthermore, the vehicle body includes a plurality of groups of parallelly arranged upright posts, a plurality of groups of cross beams are fixedly connected between the upright posts, and the universal wheels are arranged at the lower ends of the upright posts.

[0008] Furthermore, the tool support plate is arranged at the upper end of the crossbeam and is fixedly connected to the column.

[0009] Furthermore, the tool support plates are arranged in two groups in parallel and are respectively fixedly connected to the upper ends and middle parts of the four groups of columns.

[0010] Furthermore, the tool support plate is a rectangular structure with baffles provided on its edges.

[0011] Furthermore, the tool buttstock is a circular ring structure, and the side wall of the tool buttstock is fixedly connected to the vehicle body.

[0012] Furthermore, the tool stocks are provided in two groups and are arranged on the same side of the vehicle body.

[0013] Furthermore, the tool hook is a U-shaped structure, and one side of the tool hook is fixedly connected to the vehicle body.

[0014] Furthermore, the tool hooks are provided in two groups and are arranged on the same side of the vehicle body.
