Description

Fulcrum movable adjustable universal sledge body Technical Field The invention relates to the technical field of automobile coating, in particular to a universal skid body with an adjustable fulcrum movement. Background In an automobile coating production line, a pry body is a core carrier for conveying an automobile body and is used for realizing the transportation of the automobile body among different working sections. The transverse support of the pry body is provided with a support block with a positioning pin, and the positioning pin can be matched with a positioning hole at a corresponding position of the bottom of the vehicle body so as to support and position the vehicle body. The vehicle type switching can bring the change of the vehicle body size, and the vehicle bodies with different sizes need to be matched with skids with corresponding specifications. At present, the coating production line adopts the same type of vehicle model to be provided with the same type of vehicle body pry bodies, and the corresponding number of pry bodies are provided according to the production scheduling number. The prior art has the following defects that (1) when a new vehicle type is introduced, the existing pry body on the production line is required to be replaced or modified, if the size of the new vehicle type is too large, the pry body is required to be redesigned and produced, the operation efficiency of the production line is greatly reduced, (2) under the multi-vehicle type production scene, when the pry bodies corresponding to different vehicle types are switched, supporting facilities are required to be called, the pry body storage area is required to store pry body redundancy corresponding to each vehicle type, the more the vehicle types are switched, the more the number of pry bodies required to be stored is required to be, and (3) the storage area is required to be specially designed for the pry bodies of different vehicle types in the early design stage of the multi-vehicle type production line, and meanwhile, the intelligent scheduling and dynamic scheduling (MES system) is required to be equipped for optimizing and debugging the production process, so that the early input cost and the subsequent debugging cost of the production line are increased.
