Elevating mechanism for cutting machine head of five-axis steel tube intersecting line

Abstract

The invention relates to an elevating mechanism for a cutting machine head of a five-axis steel tube intersecting line, wherein, an upright column is arranged on a longitudinal moving part of the cutting head, and the front surface of the upright column is fixedly equipped with a front screw rod axle seat, a rear screw rod axle seat, a fixed motor, a reducer and a screw rod; and the upright column is connected with a lifting board through a linear guide rail pair and a limit device, and the back side of the lifting board is provided with nuts which are meshed with the screw rod. By means of control by a precise linear guide rail pair, a precise ball screw pair, a contact and inductive up-and-lower limit switch and a full closed-loop AC servo motor, the elevating mechanism achieves fast elevating speed, accurate location, simple and convenient assembly, stable and reliable mechanical action, good machining accuracy, high cutting efficiency and larger elevating load-carrying capacity, wherein, the linear guide rail pair enlarges the travel range of the cutting head which reaches 300mm.

Description

technical field [0001] The invention relates to the field of steel pipe processing equipment, in particular to a five-axis steel pipe intersecting line cutting machine. Background technique [0002] At present, the cutting head lifting mechanism used in CNC intersecting wire cutting machine equipment has a complex structure, and the adjustment is controlled by a servo motor to control the lifting shaft. The control of the lifting speed is relatively slow, the positioning accuracy is low, and the manufacturing cost is high. Contents of the invention [0003] Aiming at the defects that the above-mentioned existing steel pipe cutting machine is difficult to cut complex steel pipe intersecting lines, and cannot cut grooves, etc., the applicant provides a five-axis steel pipe intersecting line cutting machine cutting head lifting mechanism with reasonable structure and easy operation, so that it can Efficient and accurate cutting of complex steel pipe intersecting lines, and ca...
