V-shaped swing head mechanism and water cutting machine tool

Abstract

The invention provides a V-type swing head mechanism. The machine tool at least has the following beneficial effects that firstly, lines penetrate through the axis of a shaft A and the axis of a shaft B, so that winding between the lines and cables is reduced to a great extent when a cutting head rotates, a foundation is laid for large-angle and multi-direction cutting, and large-angle conical surface cutting or curved surface cutting can be achieved; secondly, a swing head is provided with a few moving components, namely, the main moving components include a shaft A rotating base and a shaft B rotating base, so that the structure is simple, weight is low, and the processing precision and reliability are easily guaranteed; thirdly, a rotary shaft can rotate by an ultra-high angle, especially a specific feasible scheme is provided for rotary shafts to rotate by + / - 360 degrees, and different from the limiting method in the prior art, the specific scheme is one of innovations of the swing head mechanism.

Description

technical field [0001] The invention relates to a water cutting machine, in particular to a V-shaped oscillating head mechanism and a water cutting machine tool adopting the V-shaped oscillating head mechanism. Background technique [0002] In the field of water cutting machine tools, the cutting head movement mode can preferably be five-axis movement mode or four-axis movement mode, which first realizes X-axis translation, Y-axis translation, and Z-axis translation. Secondly, it also uses the swing head mechanism to realize cutting Further movement of the head itself. [0003] The motion mode of the existing swing head mechanism can be decomposed into rotation around the rotary axis and swing around the yaw axis. The combination of the two motion modes can not only correct the cutting slope, but also be used for workpieces with a certain slope Processing, and has the function of processing cones, bevel gears, and uniformly rotating surfaces, expanding the application field...

AI Technical Summary

Problems solved by technology

[0005] First, because there are high-pressure water pipes, sand inlet hoses, air pipes, cables and other auxiliary structures on the swing head, the rotary shaft and yaw shaft may interfere with and entangle with these auxiliary structures when rotating;

[0006] Second, the angle range of the rotation angle of the rotary shaft is limited by the limit device. The limit device used in the cutting machine tool in the prior art can only meet the limit within two circles (that is, 720 degrees) at most.
