Embodiment Construction

[0019] In the figure, tool loading devices are installed along the assembly line, eg at assembly stations for positioning the sides of the vehicle body. The loading device shown is adapted to be handled by two operators 1 and 2, each working on one side of the assembly line. Each operator 1 and 2 is responsible for positioning one side of the body.

[0020] The loading device comprises a rigid frame 10 in the form of a gantry. It comprises vertical legs 11 and 12 on either side of the assembly line and a cross beam 13 extending between the legs 11 and 12 transversely to the direction of travel of the assembly line. The two legs 11 and 12 are carried into two cavities 71 and 72 formed in the ground 21 on either side of the assembly line.

[0021] A rolling bed 23 supporting the body 20 has been placed under the mast 10 between the legs 11 and 12 .

[0022] The tool loading device also includes two tool loading devices arranged on either side of the mast, each tool loading de...

Abstract

The invention relates to a tool-loading device for a vehicle body assembly station. The inventive device comprises at least one means for loading a tool (61, 62), which is designed to convey the tool(61, 62) from a storage position (101, 102, 301, 302) to a loaded position (201, 202) in which the tool (61, 62) is disposed opposite the body (20). The invention is characterised in that the loadingmeans is arranged so as to enable the tool (61, 62) to move in translation between the storage position (101, 102, 301, 302) and the loaded position (201, 202) along an essentially-vertical axis.

Description

technical field [0001] The invention relates to the field of motor vehicle body assembly. It relates more specifically to the positioning of the bodywork. Background technique [0002] Each motor vehicle requires the use of tools specially adapted to its assembly. Traditionally, the tool is permanently installed along the assembly line at a workstation dedicated to a particular type of vehicle. [0003] Various solutions have been developed to enable a more flexible use of workstations with the aim of reducing the area occupied by these workstations and the associated operating costs and cycle times. [0004] A scheme known by its French acronym MMAC (Machine Modulaire Assemblage Carrosserie) or MFAC (Machine Modulaire Fabrication Carrosserie) consists of a turret that supports the Multiple tools at the front and rear of the body. The tower rotates so that the appropriate tool can be selected and brought into opposition to the body. [0005] known as Another solution ...
