[0002] In the prior art, the positioning of the arc voltage during plasma cutting usually adopts capacitive height adjustment positioning or imported arc voltage height adjustment control. The capacitive height adjustment can only basically meet the distance between the cutting nozzle and the workpiece before cutting. The distance between the two cannot be kept constant, which affects the cutting quality; although the imported arc voltage adjustment and pneumatic anti-collision device can achieve the ideal cutting effect, the imported original is expensive, the equipment investment is large, and the maintenance cost of the equipment is also high. very high

The invention relates to a plasma initial positioning and anti-collision device which is characterized in that a bracket and an installation plate are adjusted and connected as a whole through bolts by an adjusting frame; a cylinder is fixed on the installation plate; an output shaft of the cylinder is provided with a connecting plate; the left side and the right side of the connecting plate are respectively provided with a proximity switch; a guide rod is connected on the connecting plate; a clamper is adsorbed on the installation plate and provided with the proximity switch; the surface of the installation plate is embedded with a plurality of magnetic steels; the clamper is provided with a positioning pin. The plasma initial positioning and anti-collision device of the invention has simple, compact and reasonable structure, exact initial positioning, low investment cost, lightness and durability and long service life, greatly reduces the maintenance cost, and effectively has self-protection function of the cutting torch during the cutting process under the unsafe situation or the situation that the operator is not skilful, thus reducing the loss.
Description
technical field [0001] The invention relates to a plasma initial positioning and anti-collision device, in particular to a necessary device used in a gantry-type numerical control plasma cutting equipment, and belongs to the technical field of plasma cutting equipment. Background technique [0002] In the prior art, the positioning of the arc voltage during plasma cutting usually adopts capacitive height adjustment positioning or imported arc voltage height adjustment control. The capacitive height adjustment can only basically meet the distance between the cutting nozzle and the workpiece before cutting. The distance between the two cannot be kept constant, which affects the cutting quality; although the imported arc voltage adjustment and pneumatic anti-collision device can achieve the ideal cutting effect, the imported original is expensive, the equipment investment is large, and the maintenance cost of the equipment is also high. very high.
