A car door hanger centralizing system

Abstract

The invention provides a door hanger straightening system, comprising: an upper straightening device, including an upper straightening wheel and an upper righting track cooperating with the upper righting wheel; a lower righting device, including a lower righting wheel, and a The lower centralizing part of the door spreader, the centralizing part and the base of the material trolley following the rear part of the door spreader, the centralizing part of the material trolley includes two parallel uphill tracks, two parallel smooth tracks and two parallel The downhill track of the door spreader is arranged on the upper part of the base, and the two uphill tracks, two smooth tracks and two downhill tracks of the material trolley centralizer are symmetrically arranged on the door hanger Both sides of the lower buttress. In the door hanger of the present invention, under the combined action of the upper righting device and the lower righting device, the swaying amount of the door hanger is greatly reduced, and the centering part of the material trolley will not interfere with the door hanger track of the lower centering part of the door hanger. Low manufacturing cost.

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 the upper righting device, and the upper righting device of the door hanger has poor stabilizing effect;

[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
