Intelligent pneumatic chuck and laser cutting machine

Abstract

The invention discloses an intelligent pneumatic chuck and a laser cutting machine. The intelligent pneumatic chuck comprises a mounting casing, a rotator assembly and a driving device; the rotator assembly is arranged in the mounting casing; the driving device is arranged at the back end of the mounting casing and is connected with the rotator assembly; the rotator assembly comprises a rotating seat, an air cylinder and a plurality of clamping assemblies; the plurality of clamping assemblies are arranged at the front end of the rotating seat in an evenly distributed manner in the circumferential direction at equal angles; the air cylinder is arranged in the rotating seat; a piston rod of the air cylinder is connected with the clamping assemblies; and a detecting mechanism is further arranged in the rotating seat and is connected with the piston rod of the air cylinder. The intelligent pneumatic chuck and the laser cutting machine have the beneficial effects as follows: when the pistonrod of the air cylinder drives the clamping assemblies to be opened or closed, the detecting mechanism can detect the stroke of the piston rod of the air cylinder, the pipe clamping states of the clamping assemblies can be known through analysis, the problems that the pipes are flattened due to clamping or the models of the pipes are wrong can be fed back timely, mistakes of laser cutting or damage to a laser cutting head can be avoided, the laser cutting efficiency can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to an intelligent pneumatic chuck and a laser cutting machine. Background technique [0002] Laser cutting has the advantages of smooth cutting surface, high cutting efficiency and high cutting quality, so laser cutting has been widely used. Laser cutting machine is one of the application examples. Generally, laser cutting machine cuts after clamping the pipe through the chuck However, the chucks currently on the market lack a stroke detection device. When processing thin pipes, it is easy for the chuck to flatten the pipe, or due to manual operation errors or problems with the pipe feeding machine, the wrong type of pipe is used. The lack of a stroke detection device makes it impossible to learn the above-mentioned situation and continue processing, resulting in problems in laser cutting, waste of materials, and even damage to the laser cutting head. Eventually, it needs to b...

AI Technical Summary

Problems solved by technology

The electric chuck of the laser pipe cutting machine allows the through hole of the used pipe, which can improve the processing accuracy of the pipe, and can widely adapt to the clamping requirements of various diameter round pipes and special-shaped pipes, and the clamping force is adjustable. It can realize the automatic control of chuck loosening, high degree of automation and high work efficiency, but it is only suitable for electric chucks and cannot be applied to pneumatic chucks
