Description

Technical Field

[0001] The utility model relates to the technical field of plasma cutting equipment, in particular to a plasma cutting gun clamping device. Background Art

[0002] Plasma cutting guns use the heat of a high-temperature plasma arc to partially melt the metal at the workpiece cut, and use the momentum of the high-speed plasma to discharge the molten metal to form a cutting seam. It is widely used due to its advantages such as fast cutting speed, high cutting accuracy, easy setting of cutting conditions, easy automation and unmanned operation, and relatively low cost.

[0003] Currently, the most commonly used plasma cutting gun clamp device on CNC cutting machines is a magnetic cutting gun clamp, which can be disengaged under the action of external force, prompting the sensor to alarm and stop working. It can continue to work after being reinstalled. However, the cutting machine will be subjected to high temperatures during operation. Especially when the plasma cutting gun and the flame cutting gun are used in combination, the magnetic force will be weakened and it will not be able to be firmly attracted. Based on these problems, Chinese patent CN220372417U discloses a plasma cutting gun clamping device. Through the coordinated design of a rectangular spring and a conical boss and a conical slot, it can ensure that the plasma cutting gun can be reset quickly and accurately after a position change. The design of the fixed seat being movable on the mounting plate can realize position adjustment by driving the gun clamp together with the fixed seat, thereby avoiding the problem of inaccurate workpiece accuracy caused by the displacement of the cutting gun position, which is convenient and flexible.

[0004] The plasma cutting gun needs to be fixed with multiple sets of fasteners. The fasteners need to be assembled before installation and installed in designated positions during installation. The whole process not only wastes the staff's time, but also reduces the efficiency of the clamping device. Utility Model Content
