A CNC four-axis device

Abstract

The invention discloses a numerical control four-shaft device which comprises a base (1), a transverse rotating shaft (2) and a longitudinal rotating shaft (3). The numerical control four-shaft device disclosed by the invention adopts a device which is composed of the base, the transverse rotating shaft and the longitudinal rotating shaft, wherein the transverse rotating shaft is horizontally arranged on the base and is driven by a controlled H servo motor through an H speed reducer, the transverse rotating shaft does a rotating motion around the transverse shaft which is parallel with a working platform; the longitudinal rotating shaft is composed of a Z speed reducer, a Z servo motor and a revolving working platform; the longitudinal rotating shaft is perpendicularly arranged on the center of the transverse rotating shaft; and the revolving working platform is positioned above the transverse rotating shaft and is driven by a controlled Z servo motor through a Z speed reducer, and does the rotating motion around a longitudinal shaft which is orthogonally with the transverse shaft. By adopting the technical scheme that a numerical control system of the common numerical control engraving milling machine tool is utilized to control the H servo motor and the Z servo motor to drive the workpiece to rotate in match with the cutting of a cutting too, the common numerical control engraving milling machine tool is capable of processing a four-shaft processing piece, and the purposes that the cost is reduced and the efficiency is improved are achieved.

Problems solved by technology

[0002] The rotary cutting tools of ordinary CNC engraving and milling machine tools can only perform cutting motions along the XYZ three-axis, that is, three-axis motion processing; for workpieces that need to cooperate with cutting tools to revolve around the transverse axis parallel to the table and at the same time around the longitudinal direction perpendicular to the transverse axis The processing of the axis for rotating motion, that is, the workpiece processed by the four-axis motion, is referred to as the four-axis workpiece. In the prior art, the machining center with the five-axis motion is used to process the four-axis workpiece. General-purpose metal cutting processing equipment also has high processing costs. Using a five-axis machining center to process a large number of four-axis workpieces makes the production cost of four-axis workpieces high and the production efficiency is low. Therefore, the existing technology has high costs, Low efficiency problems and deficiencies
