Central support for laser pipe cutting

Abstract

The invention relates to the field of laser cutting devices, in particular to a central support for laser pipe cutting. The outer ring of a large-through-hole bearing is fixed to a fixing base. A frameless motor is arranged on one side of the large-through-hole bearing. A slip ring is arranged on the other side of the large-through-hole bearing. A rotor of the frameless motor, the inner ring of the large-through-hole bearing and a rotary slip ring body of the slip ring are connected in sequence and have the same rotation axis. An idler wheel connecting disk is fixed to the rotating slip ring body, and the rotation axes of the idler wheel connecting disk and the rotating slip ring body are identical. Two pairs of parallel guide rails are arranged on the other side of the idler wheel connecting disk, wherein the two pairs of parallel guide rails are perpendicular to each other. Each pair of parallel guide rails is movably provided with two sliding plates. Each sliding plate is provided with an idler wheel. The four idler wheels face the rotation axis of the idler wheel connecting disk. Each idler wheel is connected with a stepping motor. The frameless motor and the stepping motors are connected with an externally arranged controller. By the adoption of the central support for laser pipe cutting, stable and synchronous rotation of the pipes can be achieved; the central support is suitable for supporting various pipes, and the cutting precision is high.

Description

technical field [0001] The invention relates to the field of laser cutting equipment, in particular to a center support for laser tube cutting. Background technique [0002] At present, the laser pipe cutting machine is an important equipment for batch cutting and processing pipes, and the center bracket is an indispensable part of the laser cutting machine. The traditional central support generally adopts the V-shaped frame or the principle of three-point fixed circle to clamp and support the shaft-shaped workpiece. The traditional central support can only support round pipes, and the pipes are easy to jump; it is difficult to maintain accurate alignment with the main rotating mechanism. Synchronous movement means movement in the same direction and at the same speed, resulting in low cutting precision. [0003] In order to ensure the accurate and synchronous movement of the pipe and the main rotating mechanism during the cutting process, some factories have introduced a ce...

Problems solved by technology

However, the motor of this kind of center bracket is located on one side of the rotation axis, and the driving force is transmitted from the side of the rotation axis to the rotation axis. During the rotation, there will be a problem of torque imbalance. It is necessary to constantly adjust the clamping device to ensure the cutting process. Accuracy; and the clamping device is controlled by cylinder transmission, which requires manual adjustment, which is laborious and has low adjustment accuracy, resulting in low cutting accuracy
