Overhead underslung trolley conveying system for body-in-white side shell plates

Abstract

The invention discloses an overhead underslung trolley conveying system for body-in-white side shell plates. The system comprises an overhead underslung trolley assembly used for overhead suspending and travel conveying of the body-in-white side shell plates, a side shell plate hoisting frame assembly used for clamping and fixing the left and right side shell plates, a four-belt pulley lifting assembly used for ascending and descending the side shell plate hoisting frame assembly in the vertical direction and a shear fork balancing assembly used for preventing the side shell plate hoisting frame assembly from swinging. The four-belt pulley lifting assembly is fixed to the overhead underslung trolley assembly; the shear fork balancing assembly is arranged between the four-belt pulley lifting assembly and the side shell plate hoisting frame assembly; and the top of the shear fork balancing assembly is connected with the four-belt pulley lifting assembly, and the bottom of the shear forkbalancing assembly is connected with the side shell plate hoisting frame assembly. The overhead underslung trolley conveying system for the body-in-white side shell plates has the advantages of beinghigh in conveying efficiency, high in production takt, low in noise, stable in operation, good in conveying effect and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile welding, and in particular relates to an air-suspended trolley conveying system used for the side wall of a body-in-white. Background technique [0002] At present, in automobile production, it is necessary to transport the side panels of the car to the main welding line of the body so that the welding robot can weld the side panels of the car. The traditional method is to use a steel monorail conveying system to transport the left and right side panels separately, and use the up and down lifting method. The most important is the electric hoist lifting mechanism. The existing steel monorail conveying system has the following defects: [0003] 1. The left and right side panels are transported to the main body welding line independently, and it is necessary to wait for the side panels to be in place before welding, which greatly affects the welding efficiency of the automobile side panels and al...

AI Technical Summary

Problems solved by technology

[0003] 1. The left and right side panels are transported to the main body welding line independently, and it is necessary to wait for the side panels to be in place before welding, which greatly affects the welding efficiency of the automobile side panels and also affects the production cycle of the main welding line

[0004] 2. The electric hoist lifting mechanism is adopted, the lifting speed is slow, which affects the production rhythm, and the force of the electric hoist chain is unbalanced, and the chain is prone to breakage

[0005] 3. The workpiece is easy to shake during the conveying and lifting process, which makes the trolley run unstable

[0006] 4. When the conveying trolley of the steel monorail conveying system runs through a large curve, there will be greater shaking and noise
