　　　　 500公斤数控座式焊接变位机 摘要 座式变位机通过工作台的回转或倾斜，使焊缝处于水平或船形位置的装置它可以实现与操作机或焊机联控应用于各种轴类、盘类、筒体等回转体工件的焊接。关 键 词：ABSTRACT 　 　　Seat type welding machine is through the displacement worktable turn or tilt, the weld seam in horizontal or boat form position of the device, which can realize Manipulator or welding machine with but connected controlling, can be applied to various axial, plate, barrel etc of axially symmetrical workpiece welding. This design topic is to design a 500 kilograms NC seat type welding displacements machine, It can realize the fluctuation on turn, tilt, and the rotary and tilt table adopts CNC control, in order to exercise with robot cooperate linkage, realize the of all kinds of workpiece weld automatic welding. 　　This design adapts the stepping motor driven directly and variator and worm and worm reducer institutions, to drive workbench is connected to rotate. So control into stepping motor pulse quantity, can control the size of workbench corner; Control into stepping motor pulse frequency, it can control the rotation speed worktable; Change stepping motor of the winding electrify sequence, days or reverse is workbench. Therefore, this shift machine can realize position control and have higher in position precision. Stepping driving system USES the open loop control, transmission mechanism is simpler, thus design, adjustment, maintenance is very convenient. 　　The design of the main content includes NC seat type welding displacements machine base, such as swing mechanism, the tilt institution of mechanical design, assembly and parts graph design, NC stepping motor selection, etc. The mechanical system should be simple, reliable and convenient operation. Write the corresponding design specification.
