A lifting and reciprocating transmission system for body assembly and welding

Abstract

The invention discloses a car body welding lifting reciprocating transmission system which comprises a reciprocating transmission mechanism, a lifting mechanism and a car body supporting mechanism. The reciprocating transmission mechanism comprises a motor, a supporting beam, a walking beam, a gear rack and a rolling wheel component, the lifting mechanism is arranged at the bottom of the motor and the bottom of each work position supporting beam, and the supporting position and the height of the car body supporting mechanism can be adjusted. The car body welding lifting reciprocating transmission system has the advantages that the transmission distance is easy to control, precision is high, the operation is stable, efficiency is high, noise is low, the control is convenient and fast, the structure is compact, manufacturing cost is low, maintenance is convenient, and high safety performance is achieved, mixed routing manufacturing transmission of different car types can be achieved without shutdown, the application range of a production line is expanded, shutdown maintenance is avoided, production cost is saved, and good popularization and utilization value is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a car body welding lifting and reciprocating transmission system which facilitates the automatic transmission of workpieces between stations during the car body welding and can effectively ensure the production cycle. Background technique [0002] At present, the degree of automation of automobile manufacturing has become higher and higher. How to realize the smooth, accurate, safe and fast transmission of car bodies between various stations has become the main research and development topic for the automobile manufacturing industry to improve the automation level. The traditional automobile body assembly and welding line transmission mainly uses manual auxiliary craft trolleys, spreaders, simple skids and other forms for inter-station transmission. Due to the low degree of automation, difficult control of production rhythm, low production efficiency a...

Problems solved by technology

Traditional automobile body assembly and welding line transmission mainly uses manual auxiliary craft trolleys, spreaders, simple skids, etc. for inter-station transmission. Due to the low degree of automation, difficult control of production rhythm, low production efficiency and poor safety, these transmission methods and other issues, it has been seldom used at present

At present, there are mainly two kinds of transmission methods commonly used. One is to use a chain transmission belt to transport the workpiece between each station, which has a high degree of automation, but the operation noise is large, the precision is low, and it is prone to failure; the other is The workpiece is conveyed by means of a single station that is independently lifted and then pushed to roll and transport the workpiece on the double rails. The degree of automation and precision is high, and the noise is also low. However, since each station is independently lifted, all stations must be lifted. It can only be transported after being lifted into place, which takes a long time, the production efficiency is low, and the synchronization between each station is difficult to control, the installation and debugging are cumbersome, and the manufacturing cost of the transport device is high

At the same time, the production line using the above transmission methods can only transport the body of one type of vehicle. When it is necessary to transport the body of a different type of vehicle, it is necessary to stop and replace the bracket of the conveying device, which is labor-intensive and time-consuming, and the operating cost is high.
