Problems solved by technology

[0002] In the automatic welding production line of automobiles, special welding fixtures are required to position and clamp the body-in-white, etc. The positioning pins and clamping mechanisms used in the welding fixtures are usually designed separately. This separate structure will Occupies a lot of space, it is difficult to apply in the case of relatively small space, especially when the surface of the workpiece to be pressed is in a closed structure, or the workpiece is a cavity structure, such as the longitudinal beam of the cabin, due to the rear floor side beam A cavity structure is formed between the clamp and the rear floor, and the pressing block of the fixture cannot press the corresponding positioning block, so it is difficult for the fixture to clamp the workpiece, and the unstable positioning will easily cause a larger welding process in the subsequent error

Abstract

The invention discloses a car body clamping positioning device suitable for a car welding production line. The car body clamping positioning device comprises a supporting base, a guide base arranged on the supporting base, a dowel pin which is arranged on the guide base for positioning a car body, a pressure plate which is arranged inside the guide base and the dowel pin, and is matched with the dowel pin for clamping the car body, and an operating mechanism which is used for controlling the pressure plate to switch between a clamping state and a loosening state; and the dowel pin is providedwith an avoiding slot for allowing the pressure plate to pass while switched to a clamping state. The car body clamping positioning device suitable for the car welding production line disclosed by theinvention is compact in structure, is convenient in layout, can stably position and clamp the car body, and improves the car body clamping and positioning effect.
