Circular tube form tracking laser cutting machine

Abstract

The invention discloses a circular tube forming tracking laser cutting machine. Two pipe supporting bodies are positioned on two sides of the X direction of a base; a first driving device drives a cross beam which can linearly slide in the X direction on the base; a first supporting plate can freely and linearly slide in the Y direction to be positioned on the cross beam; a second supporting plate can linearly slide in the Y direction to be positioned on the first supporting plate; a second driving device drives the second supporting plate to move; a cutting head can linearly sliding in the Z direction to be positioned on the second supporting plate; a third driving device drives the cutting head to move; a supporting plate can freely slide a set distance in the Z direction on the first supporting plate; a positioning hole in the X direction is formed in the supporting plate; a sensing device on the cutting head can sense the distance between a nozzle of the cutting head and a pipe to be machined and transmits the distance to a controller; and the controller controls the motion of the first, second and third driving devices. The machining of the cutting head is not affected by deformation and swinging of pipes, so that accurate machining is guaranteed, the machining precision and the production efficiency are improved, and the rejection rate is reduced.

Description

technical field [0001] The invention relates to a circular tube laser cutting machine, in particular to a circular tube shape tracking laser cutting machine. Background technique [0002] When cutting a round pipe, the cutting head is required to be above the round pipe, and the extension line of its center passes through the center of the round pipe. During the cutting process, the cutting head moves along the axis of the pipe, and the round pipe rotates around its axis. The rotary driving mechanism of the circular tube is located at one end of the circular tube. Due to the irregularity of the pipe itself and the heat deformation during the processing, the distal end of the pipe will swing when it is rotated, which cannot ensure that the centerline of the cutting head coincides with the center of the round pipe. The cutting head of the traditional circular tube laser cutting machine cannot follow the deformation and swing of the tube, resulting in offset, confusion, and e...
