Abstract

The invention discloses an overload protection mechanism applied to a multi-axis numerical control machine tool. The overload protection mechanism comprises a first gear, a second gear and a driven friction disc, wherein the first gear and the second gear are engaged with each other and arranged in a paired manner, and the driven friction disc is fixed to the first gear and is concentric with the first gear. A driving shaft is movably sleeved with the first gear through a bearing. The driving shaft is provided with an outer thread and connected with a screw nut through the outer thread in a threaded manner. The screw nut is fixedly connected with a baffle ring. The driving shaft is further sleeved with a driving friction disc matched with the driven friction disc. The driving shaft is provided with friction keyways formed in the axial direction of the driving shaft. The driving friction disc is matched with the friction keyways through keys so that the driving friction disc can move in the axis direction relative to the driving shaft. The driven friction disc is provided with friction protrusions / friction grooves. The driving friction disc is provided with friction grooves / friction protrusions matched with the driven friction disc. A first spring is mounted between the baffle ring and the driving friction disc.

Description

technical field [0001] The invention relates to the technical field of machining. Background technique [0002] 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. Contents of the invention [0003] The purpose of the present invention is to provide a high-precision processing machine tool, which can complete functions such as turning, milling, boring, drilling, and planing through one clamping, and can control the axial movement of the tool, thereby increasing the processing area. [0004] In order to realize the above-mentioned technical purpose, the technical scheme adopted in the present invention is as follows. [0005...
