Abstract

The utility model discloses an NC flame cutting machine, which is composed of machine frames, a transverse beam of a machine body, beams of guideways, a photoelectric tracer of an NC system, a manually operated clutch, and a riser with a cutting torch. The photoelectric tracer 5 and the riser 10 with the cutting torch 12 are fixedly arranged on a connecting plate 11 with gear racks, and the connecting plate 11 is clamped on the transverse beam 4 of a machine body via a rolling wheel 18 for realizing the simultaneous movement of the trace and the cutting. The manually operated clutch 9 causes transmission gear wheels to mesh and to do gapless transmission and controls the cutting torch 12 to move along a figure track according to the photoelectric tracer 5. The riser 10 with a cutting torch can be used for adjusting the thickness of materials to be cut. The utility model has the advantages of good cutting precision, simple structure, and convenient use and can realize high quality cutting for complex figures.

Description

NC flame cutting machine

The utility model relates to Metal Cutting machinery, relates in particular to NC flame cutting machine.

At present, in mechanical processing industry, widely used hand cut machine of sheet metal blanking moulding and mechanical cutter, it is low to exist cutting accuracy, surface quality is poor, is difficult to cut complicated shape, though and numerical control cutting machine cutting accuracy height, but, be difficult to popularize and use complex figure and the non-circular curve difficulty of then programming.

The purpose of this utility model is to provide a kind of cutting accuracy height, simple in structure, easy to operate, the NC flame cutting machine that can need not to programme and just can cut complex figure.

To achieve these goals, the utility model adopts photoelectric tracer control Numerical control cutting technology, fixedly mounting lower guideway on the fuselage crossbeam, photoelectric tracer is fixedly mounted on the connecting plate that has tooth bar jointly with the lifter that cutting torch is installed, positioning roller is installed by support in the connecting plate two ends, roller rolls to cooperate and is stuck on the last lower guideway of fuselage crossbeam, and motor and driving gear are set on the fuselage crossbeam, driving gear and the engagement of connecting plate tooth bar.

The manual backguy clutch of fixed installation on frame, eccentric shaft is set in the clutch, handgrip is set on the eccentric shaft, steel wire rope is installed at the eccentric shaft two ends respectively, steel cable connects motor cabinet by spring, gear of installing on the motor cabinet and the engagement of connecting plate tooth bar, and another root steel wire connects another motor cabinet by spring, gear of installing on the motor cabinet and driven gear engagement, driven gear is then fixedlyed connected with the lathe driving wheel.

The hexahedron main shaft of band tooth bar is housed in the lifter that cutting torch is installed, two groups of eccentric wheels that main shaft is installed in up and down on the positioning seat support the location, mounting teeth wheel shaft movingly on positioning seat, the tooth bar engagement on gear on the gear shaft and the hexahedron main shaft, gear shaft one end connects motor.

Owing to adopted the manual backguy clutch configuration of photoelectric tracer and cutting torch linkage structure and elimination gear backlash, and the cutting torch lifter, the utility model cutting accuracy height, simple in structure, flexible operation need not programming and just can realize high-quality cutting to complex figure.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.
