Attitude control device for five-axis waterjet head with horizontally installed swing axis

Abstract

A five-axis water cutting head posture control device provided with a horizontally mounted swing shaft comprises a main shaft (22) and a water cutting head (17), wherein the main shaft (22) drives the water cutting head (17) to perform horizontal plane rotary motion, the main shaft (22) performs left and right, up and down as well as front and back three-dimensional motion under the driving of a driving mechanism, and the water cutting head (17) and a water switch (20) are mounted on a water switch base (19). The posture control device is characterized in that the water switch base (19) is mounted on an output shaft of a harmonic speed reducer (12) which is driven by a swing shaft servo motor (7), the harmonic speed reducer (12) drives the water cutting head (17) to perform deflection motion in a vertical plane, an included angle of an axis of the main shaft (22) and an axis of the output shaft of the harmonic speed reducer (12) is 90 degrees, and the maximum deflection angle of the output shaft of the harmonic speed reducer (12) is minus and plus 90 degrees. According to the five-axis water cutting head posture control device provided with the horizontally mounted swing shaft, the swing range is large, and the cutting accuracy is high.

Description

technical field [0001] The invention relates to a water cutting technology, especially a five-axis (X, Y, Z, rotation, swing) control technology of a water cutting head, specifically a five-axis water cutting head attitude control with a horizontally installed swing axis device. Background technique [0002] At present, when waterjet equipment is cutting, 1) sometimes it is necessary to obtain an ideal vertical cutting surface, 2) sometimes in order to facilitate the welding connection of metal sheets, the section must be grooved, 3) cutting cones, 4) cutting cones Gears or cams, 5) cutting rotating surfaces with equal rotation angles, and to achieve these five purposes, the waterjet head must be deflected. At present, the commonly used methods include manual adjustment and adjustment through the yaw mechanism. Manual adjustment is only suitable for linear cutting surfaces, and the adjustment is difficult, inefficient, and intensive. It must be stopped to proceed. Therefore...
