Automatic van-type car rear door hanging and mounting system

Abstract

An automatic van-type car rear door hanging and mounting system is a tool and equipment for manufacturing car body-in-white. The system uses an advanced PLC programming program control mode and a touch-stopping and touch-starting circuit so as to control the motion and stroke of the system; adopts mechanical transmission ways such as worms, strand cables, gears, and hinges so as to carry out transmission of stroke and motion of the system, achieves the complete automation, solves the shortages of low work efficiency, large work strength, engineering harms to workers and machine, and bad affects on the quality of car-in-white, which are caused by manually moving and mechanical assistant when a rear door is hanged, mounted and adjusted to a car-in-white, and can at least save three operation workers for each production line which runs for all day long for entrepreneurs; so that the human cost of three workers such as salaries and welfares is saved, and the production cost of the product is greatly reduced. The system can be universally applied to the hanging and mounting work of car rear door of cars such as minibus-type commercial cars, business purpose cars, and the like of any car producing entrepreneurs. The system has the advantages of advanced technology, excellent and stable performance, wide application range, safety, and reliability.

Description

Technical field [0001] The invention belongs to equipment and tools for manufacturing automobile body in white. Background technique [0002] At present, the body-in-white adjustment production line of van-type van automobile manufacturing enterprises is for the tailgate of vans (also known as tailgate welding assembly, or back door or rear door welding assembly, for the convenience of description, the following will be unified It is called the tailgate.) to adjust and mount, some adopt the relatively primitive manual lifting method, and some use the mechanical assist method. The tailgate is a relatively heavy auto part weighing nearly 100 jins. These two mounting methods not only have low labor efficiency, high labor intensity, ergonomic injuries, and possible bruises, smashes, and cuts to employees. Unsafe factors that affect the occupational safety and health of employees; at the same time, there are quality hazard factors that affect the quality of automobile body-in-wh...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the manual lifting method and the mechanical assisting method to adjust and hang the tailgate, there are disadvantages such as low labor efficiency, high labor intensity, ergonomic injuries and possible bruises, smashes, and cuts that seriously affect the occupational safety and health of employees. Safety factors; at the same time, there are quality hazard factors that affect the quality of automobile body-in-white, such as easy bruises and concave parts, etc.
