Truck chassis assembly line

Technical Field

The invention relates to the technical field of automobile production lines, in particular to a novel truck chassis assembly line.

Background

An automobile assembly line is generally formed by combining a plurality of assembly lines. The equipment and space layout is carried out according to the assembly process flow of the production vehicle type. In recent years, automobile products are updated and updated more quickly, the traditional automobile assembly line is not flexible enough, and when new products are released, the assembly line needs to be greatly improved or newly built, so that the cost is high.

At present, truck chassis in China are assembled in a forced moving mode, a land drag chain is combined with a double-plate chain, a trolley in an on-line assembling process moves products from the previous station to the next station through conveying equipment, and a whole truck falls on the double-plate chain for assembling after tire assembling is finished. This type of method is generally used by assembly workers on both sides of an assembly line for fixed vehicle types and is widely used in mass production.

The existing truck assembly line adopts a ground drag chain and a double-plate chain, a large amount of equipment foundations must be excavated during construction, the requirement on ground bearing is met, the occupied area is large, and the manufacturing cost is high; during assembly of the assembly line, the heights of all the stations are basically consistent, and partial station assembly workers need to bend over or squat for a long time for assembly, so that unqualified products are increased, and the workers are not healthy.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, a novel assembly line for truck chassis comprises an AGV transfer area 1 and an assembly area 2 distributed on one side or both sides of the AGV transfer area 1, wherein a plurality of stations 3 are arranged in the assembly area 2 side by side, a heavy-duty AGV5 is arranged in the AGV transfer area 1, the heavy-duty AGV5 is provided with a support for supporting the truck chassis, the heavy-duty AGV5 is provided with a station 3 where the truck chassis can move transversely in the AGV transfer area 1 or longitudinally enter the assembly area 2, a lifting mechanism 4 capable of supporting the lifting of the truck chassis is arranged in the station 3, the lifting mechanism 4 comprises a front-end lifting mechanism 41 and a rear-end lifting mechanism 42, the two front-end lifting mechanisms 41 are symmetrically arranged in the station 3 near the AGV transfer area 1, the rear-end lifting mechanism 42 is arranged on the side far from the AGV transfer area 1, both the front-end lifting mechanism 41 and the rear-end lifting mechanism 42 are provided with a lifting arm 43 capable of lifting up and down, the lifting height of the lifting arm 43 of the station 3 can be independently adjusted according to different assembling procedures of the station 3 in each station 3.

In this scheme, assembly process adopts chassis upset assembly, the suspension adopts and turns over the dress, accomplish the upset of back chassis and go to adorn upper part again, turn over the dress section and adopt heavy AGV5 to transport, with the transport of truck chassis to station 3 on, lift arm 43 by lifting mechanism 4 and form the support to the truck chassis, heavy load AGV5 leaves after the lifting, then lift arm 43 and go up and down to the height that is fit for the assembly personnel to operate, the health influence that the assembly caused of bowing for a long time or squatting in the work has been reduced.

In practical applications, in the front end lifting mechanism 41, the lifting arm 43 is disposed at a side of the column 44 of the front end lifting mechanism 41, and the column 44 can rotate with the base to adjust the orientation of the lifting arm 43. Before heavily loaded AGV5 carried the truck chassis and got into station 3, the cylinder is rotatory, will hold in the palm lift arm 43 towards AGV circulation district, forms to heavily loaded AGV5 and dodges, makes things convenient for heavily loaded AGV5 to get into station 3, after heavily loaded AGV5 stops steadily, lifts arm 43 and turns to the chassis below again, holds in the palm lift arm 43 simultaneously lifting afterwards, forms to the chassis and lifts.

In practical application, the lengths of truck chassis of different models are different, so that in order to adapt to truck chassis of different models, the distance between the front end lifting mechanism 41 and the rear end lifting mechanism 42 is adjustable, the rear end lifting mechanism 42 is movable, ground rails are arranged on two sides of the station 3, and the rear end lifting mechanism 42 can move back and forth on the ground rails.

In practical application, the truck chassis length of different models is inconsistent, therefore in order to adapt to the truck chassis of different models, distance is adjustable between each support on heavy-duty AGV5, support on heavy-duty AGV5 includes front axle movable support 51, middle axle movable support 52, rear axle fixed support 53, heavy-duty AGV 5's top both sides are equipped with the slide rail, controllable slip on the slide rail is adjusted by motor drive in front axle movable support 51 and middle axle movable support 52 bottom, the distance between each support.

The working principle of the invention is as follows:

the novel truck chassis assembly line mainly comprises the following steps in the working process:

firstly, adjusting each supporting position by the heavy-load AGV5 according to the chassis model, loading the chassis of the truck, and moving in the AGV transferring area 1;

secondly, after the heavy-load AGV5 reaches the target station, the heavy-load AGV drives into the station 3 vertically;

thirdly, the lifting arm 43 of the front end lifting mechanism 41 turns to the lower part of the chassis, and the rear end lifting mechanism 42 moves to a proper position;

lifting by the lifting mechanism 4, and lifting the truck chassis away from the heavy-load AGV 5;

fifthly, the heavy-load AGV5 exits the station 3;

sixthly, the lifting mechanism 4 lifts the truck chassis to a proper position according to the preset condition, and the staff assemble the truck chassis.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the foregoing embodiments are merely illustrative of the technical spirit and features of the present invention, and the present invention is not limited thereto but may be implemented by those skilled in the art.
