Device for auxiliary adjusting the cutting nozzle angle of cutting machine

Abstract

The invention relates to a device for assisting in adjusting the cutting nozzle angle of a gas cutter. The main structure of the device comprises a graduated base, a gliding block, an edging connecting plate, a transverse lever, a balance weight and a trolley. One end of the graduated base is arc-shaped; an arc-shaped groove is opened in the middle of the arc; the gliding block is arranged inside the arc-shaped groove in a sliding manner; scale is marked on the outer side of the arc-shaped groove on the graduated base; the cutting nozzle of the gas cutter is clamped on the gliding block; the top end of the cutting nozzle is positioned in the circle center position of the arc-shaped groove; the other end of the graduated base can be adjustably in the vertical direction and fixed close to the edging connecting plate; the edging connecting plated is fixed on one end of the transverse lever; the middle part of the transverse lever is fixed on the top of the trolley; the balance weight is fixed on the other end of the transverse lever; a connecting rod extends out of the bottom of the trolley; and a side wheel is fixed on the end part of the connecting rod and leaned against the edge of a steel plate to be cut. The device can cut a divided edge with a random angle, ensure the cutting point stays unchanged, and cut a divided edge with a remaining root cutting and a random angle on a thick plate.

Description

technical field [0001] The invention relates to a gas cutting machine, in particular to a device for assisting in adjusting the cutting nozzle angle of the gas cutting machine. Background technique [0002] With the development of ship production technology and the need for the application of large tonnage ships in practice, the shipbuilding capacity of shipyards continues to improve, and the tonnage of ship construction is getting larger and larger, so the plates used for ship manufacturing are also getting thicker. Since the problems caused by the increase of the thickness of the plate are becoming more and more obvious, there are certain problems when some outer plates with double curvature are connected to the plate. When the outer plate with double curvature change is connected to the plate, it is found that the edge of the vertical cut cannot be closely attached to the change curvature plate, resulting in a gap, which affects the assembly and welding quality, so the pl...

Problems solved by technology

Manual operation is performed by manual cutting operation, which can cut out any angle of bevel, but the accuracy is far from the requirement, and the cutting efficiency is very low
