AUTOMATED LINE FOR PREASSEMBLING OF CHASSIS, ITS BUTT-JOINING AND ASSEMBLING WITH BODY OF AUTOMOBILE Russian patent published in 2001 - IPC

FIELD: automotive industry. SUBSTANCE: invention relates to automated vehicle assembling lines. Such line has chassis preassembling section and chassis-to-body butt-joining and assembling section over which overhead monorail conveyor for automobile body grips is installed. Units and sets of chassis are arranged in pallet jigs which are installed stationary at strictly definite height relative to basses of pallets. Pallet conveyor proper is made in form of separate roller sections furnished with self- contained drives for rotation. Lifting/lowering devices arranged on extreme positions of sections, being part of pallet conveyor, are designed for lifting and lowering of pallets from one level to the other. Roller sections of these devices are arranged square to roller sections of conveyor being coupling in upper position by means to transverse roller sections installed near floor lever to play the part crossings through which complementary articles are delivered to assembly line. Grip of monorail conveyor is made for vertical travel for lowering automobile body pallet jig and lifting body for butt-joining chassis and body and for separation of body pallet. Line is furnished with pallet movement follow-up control system. EFFECT: simplified assembling process, design of line proper, improved flexibility and reliability of line in operation, convenience of servicing at high degree of safety, reduced cost of line. 9 cl, 10 dwg
