ABSTRACT
In modern industrial production, the welding manipulator can not only reduce the labor intensity of workers, reduce the time needed for welding, but also ensure the quality of welding seam. The use of the welding machine will greatly reduce the labor load. In the premise of guaranteeing the quality of the product, it can also greatly increase the output, which will bring great economic benefits to the company. In order to adapt to the development of modern industry, higher production efficiency is needed. Therefore, it is important to study the welding machine to overcome the previous manual welding, such as high labor intensity, low production quality, low labor efficiency, poor production conditions and so on. It is of great significance to improve the production efficiency and ensure the quality of the important pipeline welding. It has good development prospects and social benefits.
This paper designs a 3 meter telescopic welding machine. The main design contents are the walking trolley mechanism, the locking mechanism and the locking principle, and the structure design of the vertical column rotary mechanism. The trolley is mainly composed of a car body, a driven wheel and a driving wheel, and is driven by a two direct connection motor through a reducer to drive the driving wheel. The locking mechanism is mainly composed of a locking guide rail and a locking nut, wherein the trapezoidal nut and the trapezoidal screw are transformed into a motion form to achieve the purpose of locking. The rotary mechanism is mainly composed of rotary bearing and driving gear. According to the rational design of structure and function, the cross roller bearing with outer teeth is chosen to carry large axial and radial force, and the purpose of turning is achieved. The speed of rotation is realized by the reducer and the transmission ratio of the small gear.
The whole structure function of each part is explained by 3D modeling.
