Frame assembly line trolley with adjustable width dimension

Abstract

The invention discloses a frame assembly line trolley with the adjustable width dimension. The frame assembly line trolley comprises a trolley support, wherein wheels are arranged at the bottom of the trolley support; roller beds are arranged on two sides of the top of the trolley support, fixing plates are fixed at two ends of the top of the trolley support, adjusting stop blocks are fixed on the fixing plates, and the distance between the adjusting stop blocks corresponds to the width of a longitudinal beam of a frame. The width dimension of the trolley is adjustable by the aid of structures of the fixing plates and the adjusting stop blocks, and the position can be adjusted conveniently and effortlessly in the direction of the longitudinal beam of the trolley; the adjusting stop blocks of the trolley can be replaced quickly after replacement of models, production assembly of frames with different models is met under the condition that the trolley is unchanged, meanwhile, the front-and-back position of the longitudinal beam can be fine-adjusted conveniently through combination of the trolley with the roller beds, the trolley is simple and reasonable in structure, the longitudinal beam is mounted conveniently, operation is reliable, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of commercial vehicle frame production equipment, in particular to a frame assembly line trolley with adjustable opening size. Background technique [0002] The trolley can run along the line, and the distance-adjustable conveyor line has been more and more widely used in the assembly and production of large automobile parts such as frame and axle since the late 1990s. The serialization of medium and heavy-duty truck products makes the variation of frame width and size of different models tend to be intensive. Generally, the width of the frame reaches about 950-1100mm, and the weight reaches about 900kg-2 tons. At present, when realizing the assembly and production of multiple models on the same line, it is necessary to replace the trolley, which consumes a lot of manpower and material resources; in addition, the weight of a single longitudinal beam of a medium-duty frame is relatively large, so it is labor...

Problems solved by technology

At present, when realizing the assembly and production of multiple models on the same line, it is necessary to replace the trolley, which consumes a lot of manpower and material resources; in addition, the weight of a single longitudinal beam of a medium-duty frame is relatively large, so it is laborious to fine-tune the front and rear positions of the longitudinal beam after it goes online
