Design of Rotary Transmission Mechanism of the 5-ton Front Frame Parts Welding Positioner
Abstract:
In our country, the welding positioner has become a kind of indispensable manufactural equipment, designated as welding assistant machine. In the last decade, this product has developed a lot in our engineering and mechanical area of our country, and also being widely applied. The usage of welding positioner can shorten the welding auxiliary time, improve the working efficiency, reduce the working intensity, insure and improve the welding quality, and give a full play to the performance of various welding methods. With the computer technology developing to be more intelligent, and dynamic control with information technology being wildly used in the manufacture, the welding positioner is also developing to be intelligent, multi-functional, large-scale, compositive, high accuracy and dependable. This work of design aiming to the assembly and welding of the 5-ton front frame parts, it explains the composition and structure of the L-type dual-rotary welding positioner. Its rotary transmission mechanism and the L-arm structure is a core part of this design, it mainly involve the choice and design of various transmission methods and design as well as L-arm with the structural design and strength calculation. 源¥自%六^^維*論-文+網=www.aftnzs.live
