Plasma cutting gun displacement colliding-proof device

Abstract

The present invention relates to welding and cutting equipment technology, and is especially one plasma cutting torch collision preventing device for numerically controlled plasma cutting machine. The plasma welding torch collision preventing device includes one turning plate and one bottom ring connected together, one lower clamping ring with permanent magnet and inductor type approach sensor, one blocking iron set between the bottom ring and the lower clamping ring, one electrically insulating bakelite sleeve inside the conic hole of the lower clamping ring, and one upper clamping ring set around the upper end of the bakelite sleeve and connected to the lower clamping ring; and the plasma cutting torch is set inside the upper clamping ring and the bakelite sleeve. The present invention protect the plasma cutting torch by means of the inductor type approach sensor to send out signal, the control system to perform corresponding commands, and detection coil and the lower clamping ring to separate or displace.

Description

technical field [0001] The invention relates to a displacement anti-collision device for a plasma cutting torch, in particular it is used for cutting torch protection (in the range of 360°) during the movement of a numerically controlled plasma cutting machine, and belongs to the technical field of welding and cutting equipment. Background technique [0002] In the prior art, the plasma cutting torch only relies on clamping at two points to realize longitudinal and transverse anti-collision functions in the plane. If it is over-clamped, the plasma cutting torch will break the holder due to collision; if the two points are not clamped properly or not fully clamped, the plasma cutting torch will continue to run without a stop signal and cause damage . Like this, expensive plasma cutting torch and holder will cause huge loss to user. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a plasma cut...
