Vehicle door lifting appliance righting system

Abstract

The invention provides a vehicle door lifting appliance righting system which comprises an upper righting device and a lower righting device. The upper righting device comprises an upper righting wheel and an upper righting rail matched with the upper righting wheel for guiding; the lower righting device comprises a lower righting wheel, a vehicle door lifting appliance lower righting part matchedwith the lower righting wheel, a material trolley righting part following the rear part of a vehicle door lifting appliance and a base; the material trolley righting part comprises two uphill rails arranged in parallel, two stable rails arranged in parallel and two downhill rails arranged in parallel; and the vehicle door lifting appliance lower righting part is arranged on the upper portion of the base, and the two uphill rails, the two stable rails and the two downhill rails of the material trolley righting part are symmetrically arranged on the two sides of the vehicle door lifting appliance lower righting part correspondingly. Under the combined action of the upper righting device and the lower righting device, the shaking amount of the vehicle door lifting appliance is greatly reduced, interference between the material trolley righting part and a vehicle door lifting appliance rail of the vehicle door lifting appliance lower righting part is avoided, and the manufacturing cost islow.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to an uprighting system for a door hanger. Background technique [0002] Usually, the door assembly line of the automobile assembly workshop is generally equipped with an accompanying material trolley. The material trolley is placed between two door spreaders, and the forward power is obtained by hanging on the door spreader. Since the hanging height of the door hanger is high, the lower end is not fixed. When people are working, the door spreader is prone to force and shakes, which affects the operation accuracy. In order to reduce the swing of the spreader, the industry generally installs an upper righting and stabilizing device above the spreader, such as figure 1 As shown, but the effect is not good. Usually, when the spreader is working at the installation position of the inner panel of the car door, the door needs to be installed to open the door, which will cause ...

AI Technical Summary

Problems solved by technology

[0005] (1) There is only an upper righting device, and the effect of righting on the door spreader is poor;

[0006] (2) Add the figure attached at the lower end of the door hanger figure 2 The lower righting device shown has a large number of material trolleys, and the chassis of the material trolley is low. The material trolleys and the newly added lower righting device will directly interfere with each other and get stuck, making it impossible to operate; dividing the material trolleys into left and right distribution lines requires additional material trolleys At the same time, it is necessary to increase the conveyor belt of the material trolley, which requires a huge investment, and there is a waste of reciprocating pick-up and walking for employees;

[0007] (3) The swaying of the car door has a great influence on the assembly quality of the door inner panel installation station, and the addition of righting and stabilizing devices on the whole line will cause unnecessary waste
