本课题针对龙门式火焰切割机的横梁及火焰切割头的控制进行了设计。横梁的机构设计主要对其结构的确定,之后对传动装置进行了选择及计算检验,最后对主要传动的零部件进行选择校核。其中主要对滑动丝杠和滚动丝杠的强度及传动效率等进行了计算校核。并对横梁设计中存在的结构部件的联接问题进行了改进。火焰切割头是在传动装置的基础上运用丝杠的转速控制运动,用单片机控制电机的转速来达到效果。对控制电路设计也做了系统的详解,主要对所涉及的键盘、显示器、主要芯片做了选取应用。

This essay analyzes that the design of the beam and the control of flame cutting head of the
gantry flame cutting machine.The design of the beam of mechanism main determining its
structure of the transmission device, then the selection and operation of the main transmission
inspection, finally the choose of the parts inspection. The major of sliding screw and rolling ball
screw's strength and transmission efficiency is calculated respectively.And problems existing in
the connect of parts, in the design of structure of the beam ,are also improved. Flame cutting in
the head is based on transmission device using screw speed control movement, with single-chip
microcomputer control motor speed to achieve results. I also make a system explanation of the
control of circuit design, involved mainly to make the selection and applications of the keyboard,
display, main chip.
Keywords flame cutting machine electrical control the design of the beam
