The railway carriage or compartment body attaches together and adopts the flip-chip location mode, and the adjustment of the various sizes of railway carriage or compartment body positioning mechanism length, width, height adopts servo motor drive guiding mechanism automatic realization, compresses tightly and adopts hydraulic pressure to press from both sides tightly. The servo motor adopts an absolute value motor. The equipment is accurately and reliably positioned and can be automatically conveyed to the next station.

The equipment adopts the following steps to realize the operation: firstly, workers adjust the equipment to the vehicle type to be produced and keep the vehicle type in a state of waiting for loading;

secondly, a worker lifts the side plate of the carriage into one side, and the second driving source pressing device is matched and adjusted to the position of the working vehicle type through the side plate conveying roller 206;

step three, a worker lifts the side plate of the carriage into the other side, and the second driving source pressing device is matched and adjusted to the position of the working vehicle type through the side plate conveying roller 206;

step four, a worker hangs the carriage bottom plate on a movable support in the middle, and can jack up and adjust the positioning position through a lifting frame 401 if necessary, so that the carriage bottom plate and the carriage side plate in the previous step are aligned to the reference and are matched with a gantry pressing device to perform point-fixing welding operation in sequence;

after the operation is finished, operating the station control system to loosen all the chucks, clicking a button to jack the lifting frame 401, and conveying the lifting frame to the next station by using a chain;

and step six, repeating the step one.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected by one skilled in the art without departing from the spirit and scope of the invention, as defined in the appended claims.
