Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile manufacturing, especially relates to a trolley for assembling automobile instrument desk. BACKGROUND

[0002] The diversification of automobile instrument desk models has brought great trouble to the production and manufacturing process of the whole vehicle. Under normal circumstances, in order to save costs, each production line of the vehicle factory will be compatible with the production of multiple vehicle models. Modular and platform design can save a lot of design and manufacturing costs, but also bring difficulties to the assembly of the instrument desk. In the prior art, the assembly process of the instrument desk needs to use a subassembly table. After assembly is completed, it is transported to the automobile assembly line station and assembled into the automobile interior. The subassembly trolley used for the instrument desk mainly controls the rotation, clamping and release of the instrument desk in the instrument assembly part process by manual mode. In order to facilitate workers to assemble parts during the assembly of the instrument desk and save working hours, the rotating disc for manual rotation is usually designed to be relatively large, which will occupy a large space area of the instrument desk trolley, making the overall volume of the instrument desk trolley too large. At the same time, it will also make the whole assembly station line occupy a large area. The instrument pipe beam is controlled by rotating the disc manually, and the fixed pin is used for fixing the assembly angle. Because some parts are assembled, the center of gravity is not uniformly stressed. It is difficult to control the manual rotation of the instrument pipe beam, and it is difficult to control.

[0003] Therefore, it is urgent to develop a trolley for assembling automobile instrument desk. When the instrument desk is assembled, the position of the instrument desk does not need to be adjusted manually, which is convenient for workshop personnel to assemble the instrument desk. At the same time, the volume of the whole trolley is relatively small, and after assembly is completed, the instrument desk can be transported to the next process by moving the trolley, so as to greatly improve the assembly efficiency.
