Wherein: 1, sliding seat; 2, holder; 3, fixed head; 4, cutting torch; 5, magnetic; 6, protective sleeve; 7, sensor; 8, holding screw; 10, screw; 11, header board; 12, connecting plate; 13, hanger; 14, slide carriage; 15, insulation sleeve.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
Shown in accompanying drawing 1,2,3, the cutting torch protective device of the numerical control plasma cutting machine of implementing according to the utility model comprises:
One end is installed in by the hanger 13 that possesses lift on the slide carriage 14 of cutting machine, and this slide carriage 14 cutting machine body is relatively done transverse movement;
Be fixedly installed on fixed head 3 on these hanger 13 other ends by screw 10;
Be fixedly installed on holder 2 on fixed head 3 upper surfaces by screw 10, the leading section of holder 2 and fixed head 3 corresponding mutually offer all identical U type gap in shape, position;
The sliding seat 1 that the upper surface of lower surface and holder 2 fits, upper surface at holder 2 possesses the circular cylindrical projection step, the lower surface of sliding seat 1 possess can with the concave station rank of described boss rank tabling, by the chimeric realization holder 2 of concavo-convex step and the centering between the sliding seat 1;
Be embedded in holder 2 and the upper surface of upper surface and holder 24 magnetics 5 of coplane mutually, these 4 magnetics 5 are divided into two groups, the two ends, the left and right sides that are arranged on described holder 2 of symmetry, the installation quantity of magnetic 5 is preferably reserved a plurality of installing holes that are used to hold magnetic 5 in advance by the duty decision of cutting machine on holder 2;
