EQUIPMENT FOR ATTACHING AND DETACHING EXTERIOR MEMBERS FOR VEHICLES

摘要

This invention relates to an equipment for automatically attaching and detaching such exterior parts as doors, a trunk, and a bonnet, etc. which are openably mounted to a vehicle body by means of such tightening means as pins, bolts, etc. on the assembling line of a vehicle. Firstly, in a door attaching and detaching equipment, the position of pins for openably attaching a door on a vehicle body is detected by the pin position detection mechanism, and the position of the pin drawing out and inserting mechanism is compensated according to the position thereof. Then, the pins can be drawn out from and inserted in the vehicle body and the door by the corresponding pin drawing out and inserting mechanism. Furthermore, the position of the door holding mechanism is compensated according to the position of the pins detected by the pin position detection mechanism, thereby causing the door to be held by the corresponding door holding mechanism. In this case, the pin drawing out and inserting mechanism and the door holding mechanism are separately installed independently and are individually driven to actuate. Next, in a fender attaching and detaching equipment, as the holding member which constitutes the holding mechanism makes a closing action by the driving means on the base plate, the holding member moves, following the position of the fender, thereby causing the fender to be held. Also, the position of the screw member screwed in the vehicle body is detected by the detection mechanism, and the position of the nut runner mechanism is compensated on the basis of the position of the screw member detected by the detection mechanism. Thereafter, the screw member can be tightened and loosened by the nut runner mechanism. Also, the above procedure is reversed when attaching the fender to the vehicle body. Furthermore, in a trunk or bonnet attaching and detaching equipment, as the trunk or bonnet is opened for the vehicle body by the trunk or bonnet opening and closing mechanism, the holding member which constitutes the holding mechanism is closed by the driving means on the base plate. So, the holding member moves, following the position of the trunk or bonnet, thereby causing the trunk or bonnet to be held. Also, the position of the screw member screwed in the vehicle body is detected by the detection mechanism, and simultaneously the position of the nut runner mechanism is compensated on the basis of the position of the screw member detected by the detection mechanism. Thereafter, the screw member can be tightened and loosened by the nut runner mechanism. Also, the above procedure is reversed when attaching the trunk or bonnet to the vehicle body.
