It is divided into Auxiliary machinery. This product has gained lots of progress and been access to a wide range of applications in Construction machinery field last decade. It can not only reduce auxiliary time in welding, lout also improve labor productivity. The welding positioner can assure and improve product quality, and make the most of performance of various welding methods. 300 kg of manual welding positioner is currently a large number of welding machinery products, which by some mechanical drive mechanism used to achieve the welding of the work piece rotation, tilt, making the welding operation faster and more convenient, improve work efficiency. In this design, the reference design data and related information, first select the institutions and the transmission mode to determine the body parts of the transmission power, torque and the strength calculation and verification to ensure the rationality of institutions so that the equipment can be designed in a given period of normal work; and then connect the various agencies designed to draw the structure diagram; The final design details, to draw the total picture, to ensure product manufacturability, ease of scale production. The design of the main content is a tilt mechanism, using the worm body, to reduce the size and achieve self-locking transmission. The entire organization is simple, reliable, easy to operate Keywords: manual type welding displacements machine; Rotary organization; Tilt institutions; Axis; Gear; worm gear 目 录 1 引言 1 1.1开发焊接
