Abstract

The invention belongs to the technical field of electric main shafts, and in particular, relates to an electric beating knife cylinder. The invention aims to solve the problem of increment of the energy consumption due to necessary preparation of a hydraulic station or air pump for a traditional beating knife cylinder. For the purpose, the electric beating knife cylinder, provided by the invention, comprises a driving motor, and a transmission mechanism arranged in the driving motor; the driving motor includes a stator and a rotor; the transmission mechanism includes a lead screw, and a lead screw nut engaged with a lead screw thread; and the lead screw nut is fixedly mounted on the rotor, and can drive axial movement of the lead screw along with rotation of the rotor. The electric beating knife cylinder drives axial movement of the lead screw through synchronous rotation of the rotor and the lead screw nut, replaces traditional hydraulic and pneumatic beating knife cylinders, and realizes the purpose of saving of energy consumption.

Description

technical field [0001] The invention belongs to the technical field of electric spindles, and in particular relates to an electric knife punching cylinder. Background technique [0002] The tool punching cylinder is mainly used for tool punching of the main shaft in the automatic or semi-automatic tool exchange mechanism of machining center machine tools and CNC milling machines, and can also be used as a clamping device for fixtures and other mechanisms. With the continuous development of technology, a new technology that integrates the machine tool spindle and the spindle motor has emerged in the field of CNC machine tools, that is, the electric spindle. At present, with the rapid development and improvement of electric drive technology (frequency conversion speed regulation technology, motor vector control technology, etc.), the mechanical structure of the main drive system of high-speed CNC machine tools has been greatly simplified, basically canceling the pulley drive a...
