Numerical control plasma torch cutting anti-collision device

Abstract

The invention provides a numerical control plasma torch cutting anti-collision device, comprising a holster, springs, a fixed seat, a located block and a torch cutting bracket, wherein, a spring location hole is arranged on the fixed seat; a counter bore is arranged on the located block; the upper hole of the counter bore is the spring location hole; the lower hole of the counter bore is a bolt location hole which is arranged on the bracket; a cutting torch is arranged in the hole of the holster; the holster is accommodated in the fixed seat; the fixed seat is arranged on the located block which is positioned on the bracket; the springs are arranged in the spring location hole of the fixed seat and the located block; a bolt passes through the bolt location hole on the bracket and the springs from bottom to top; and the upper end of the bolt compresses the spring through a nut. In cutting process, the device of the invention can effectively acts self-protecting function of the cutting torch facing to complex unknown cutting condition, thus lowering damage to minimum, well satisfying the requirements of anti-collision, and greatly reducing torch cutting repair rate.

Description

technical field [0001] The invention relates to a numerical control plasma cutting torch anti-collision device, which belongs to the technical field of thermal cutting equipment. Background technique [0002] During the processing of the plasma cutting machine, because the distance between the cutting torch and the surface of the steel plate is quite close, there will be defects on the surface of the steel plate (steel plate deformation, unevenness, objects, etc.). A spring is easy to deform, resulting in inflexible action, inaccurate reset and poor protection. [0003] At present, the collision damage of the cutting torch is usually avoided by visual observation or through the induction device; this requires the operator and the induction device to have relatively fast response capabilities, and also increases the number of maintenance of the equipment; once the induction fails, the cutting torch will be damaged. Damage may occur. SUMMARY OF THE INVENTION [0004] The p...

Problems solved by technology

[0002] In the process of plasma cutting machine processing, because the distance between the cutting torch and the surface of the steel plate is quite close, there will be defects on the surface of the steel plate (deformation of the steel plate, unevenness, objects, etc.), and it is inevitable that after a collision, the cone surface is used for positioning, which is easy to get stuck. A spring is easy to deform, resulting in inflexible movement, inaccurate reset, and poor protection

[0003] At present, the collision damage of the cutting torch is usually avoided by visual observation or through the induction device; this requires the operator and the induction device to have a relatively fast response capability, and also increases the number of maintenance of the equipment; once the induction fails, the cutting torch There is a possibility of damage
