Non-shaft deflection numerical control waterjet cutter

Abstract

A non-shaft deflection numerical control waterjet cutter comprises a deflection servo motor, an upper sliding plate and a lower sliding plate. A driving belt pulley is arranged on an output shaft of the deflection servo motor, a driven belt pulley is arranged on the lower sliding plate, the driving belt pulley is connected with the driven belt pulley through a synchronous cog belt, the lower sliding plate is installed on a bearing seat which is fixedly connected with a waterjet cutting machine vertical lifting shaft through a bearing, the upper sliding plate is placed on the lower sliding plate and is connected with the lower sliding plate in a sliding mode, the upper sliding plate is provided with a cutter head connecting rod, and the lower end of the cutter head connecting rod is connected with a cutter head body. The deflection servo motor drives the lower sliding plate to rotate, the upper sliding plate rotates with the lower sliding plate, and the upper sliding plate slides relatively on the lower sliding plate under the control of a numerical control system to enable the cutter head body to form deflection and adjust a deflection angle automatically according to a cutting graph. Deflection control of the waterjet cutter is arranged, and therefore the machining range of the waterjet cutter is expanded, machining precision and production efficiency are also improved, not only can the inclination of a cutting face be corrected, but also a groove can be machined, and the waterjet cutter is simple in structure and high in control precision.

Description

technical field [0001] The invention relates to a water cutting machine, in particular to a shaftless deflection numerical control water cutting machine. Background technique [0002] The current water cutting machines generally have horizontal and horizontal X-axis, horizontal and vertical Y-axis and vertical lifting B-axis, that is, three-axis control water cutting, and three-axis water cutting machines can only perform water cutting in the form of vertical and horizontal planes. During the cutting process, due to the energy gradient attenuation, the cutting surface is often not perpendicular to the surface of the workpiece, and the slope will vary by 3-5 degrees depending on the thickness of the workpiece. With the continuous improvement of safety and environmental protection of water cutting machines, its application fields continue to expand, and users also have higher and higher requirements for cutting accuracy. The problem of water cutting surface slope has always pl...

AI Technical Summary

Problems solved by technology

At present, because there is no suitable control mechanism for the deflection of the cutting head, only subsequent processing or multi-step cutting can be used to obtain the final required shape, the production efficiency is low, and the superiority of waterjet cutting cannot be reflected. The slope of the water cutting surface generated during cutting, and the water cutting machine that can cut the water cutting surface into grooves according to user requirements
