Description

Technical Field

[0002] Electric tricycles, with the advantages of strong applicability, flexibility, simple maintenance, convenient repair, low price, etc., can flexibly travel through narrow roads. Electric tricycles are equipped with a reverse switch, which can conveniently realize the function of forward and reverse driving. This is very practical in narrow alleys and lanes. It is very convenient for both driving and parking, and is widely used in short-distance transportation fields such as families, urban and rural areas, individual rentals, factory areas, mining areas, sanitation, and community cleaning. In the structure of an electric tricycle, the main beam is an indispensable part. The main beam is used to support various loads and transfer them, and is the main load-bearing carrier of the gravity of the electric tricycle. The positioning method of the existing main beam welding device is too complicated in operation steps, requires manual adjustment, takes a lot of time, has too low automation, reduces the welding efficiency. At the same time, since the positioning device needs to be re-adjusted and positioned for main beams of different specifications, a large amount of time and energy are wasted for each adjustment, the work efficiency is low, and due to reasons such as insufficient precision of the platform positioning and manual operation, the workpieces are easily scrapped during the welding process.
