A multi-axis CNC machine tool

Abstract

The invention discloses a workpiece clamping mechanism capable of deflecting around the Z axis in the fixed direction at a fixed angel at a fixed rotation speed. The workpiece clamping mechanism comprises a bottom plate, a big bevel gear wheel, small bevel gear wheels, a chuck body and four claw discs, wherein the bottom plate is movably connected with a movable bracket and can rotate around the axis of the movable bracket, the big bevel gear wheel is movably connected with the bottom plate and can rotate around the axis of the bottom plate, the small bevel gear wheels matched with the big bevel gear wheel are mounted on the bottom plate, the chuck body is connected with the outer portion of the bottom plate and the big bevel gear wheel in a sleeving manner and fixed to the bottom plate, and the four claw discs are the same in size and slidably connected with the chuck body. The bottom plate is mounted between the big bevel gear wheel and a third sliding plate body. The central angle of the claw discs is 90 degrees, and the four claw discs can be spliced into a complete circle. An annular step which is concentric with the big bevel gear wheel and is connected with the center of the bottom plate is arranged on the big bevel gear wheel. The other end face of the center of the bottom plate is further connected with a rotary shaft in the Z axis direction, and a planar spiral groove is formed in the back of the big bevel gear wheel.

Description

[0001] The present invention is a divisional application of an invention patent with the application date of May 25, 2016, the application number: 2016103542006, and the invention title of "Workpiece Clamping Mechanism with Orientation Around Z-axis, Fixed Angle, and Fixed Speed ​​Deflection". technical field [0002] The invention relates to the technical field of mechanical processing, in particular to a multi-axis machine tool capable of realizing functions such as turning, milling, boring, drilling and planing. Background technique [0003] The machine tools in the prior art have mature technology and high processing precision, and can realize functions such as turning, milling, boring, and drilling, but cannot effectively combine turning and planing; the tool clamping mechanism of the three-axis machine tool in the prior art It is usually fixed and cannot control the movement of the tool along the axis, thus limiting the processing area.
