The invention relates to a micro arc voltage height-adjusting device of a plasma cutter. The micro arc voltage height-adjusting device is composed of a motor protecting cover, a motor, an height-adjusting positioning plate, a coupler, an upper retaining plate, a lifting light shaft, a guide light shaft, a height-adjusting body shell, a guide bearing, an extensible rod, a lower retaining plate, a guide copper sleeve, a cutting gun clamp, a cutting gun, an automatic igniter, an igniter supporting rod, a supporting rod connecting plate, a reamed hole bolt guide sleeve, a lead device, a lead pressing plate, a lead bottom plate, a needle bearing, a spring, a hexagon socket bolt, a spring washer and a pressing plate, and a full set of arc voltage height-adjusting functions is realized through transmission of a light shaft lifting mechanism. The light shaft lifting mechanism pre-tightened by a needle bearing spring is adopted, and initial positioning and cutting height-adjusting action needed for arc voltage height-adjusting are completely finished; when a mechanical portion runs to a limit position, the mechanical portion is effectively protected from being damaged, a whole height-adjusting body is light and compact in structure and complete in function, and electrical mounting is simplified.
Description
technical field [0001] The invention relates to a height-adjusting device for a numerically controlled cutting machine, in particular to a miniature arc voltage height-adjusting device for a plasma cutting machine. Background technique [0002] In order to ensure the cutting effect of the plasma CNC cutting machine, it must be equipped with an arc voltage height adjustment device. At present, the function and structure of the arc voltage height adjustment device of CNC cutting machine are basically the same. Most of them adopt the transmission form of ball screw or screw, and set limit switches at the upper and lower limit positions of the equipment. With a full set of functions such as positioning and height tracking, the structure of the entire set of arc voltage height adjustment devices is relatively large, and most arc voltage height adjustment devices are only suitable for application on gantry type, large cantilever type and other CNC cutting machines. [0003] The a...
