Numerical control machine tool with clamping tip

Abstract

The invention relates to the technical field of intelligent manufacturing, and discloses a numerical control machine tool with a clamping tip, the numerical control machine tool comprises a base, a first support, a second support, a motor and a grinding piece, a shaft sleeve is fixedly connected to the right side of the second support and located at the tail end of an output shaft of the motor, and a limiting column is fixedly connected to the left side wall of the first support; a center sleeve is fixedly connected to the right side wall of the shaft sleeve, a rotating column is fixedly connected to the center of the top wall of the center sleeve, a first protrusion is fixedly connected to the rotating column in the circumferential direction, and a permanent magnet is slidably connected to the interior of a limiting groove. Clamping of a part to be machined is achieved through the first protrusion on the tip, multi-stage switching of the protection mechanism is achieved through centrifugal force changes at different rotating speeds in the part machining process, the automation degree is high, torque is kept to be stably transmitted according to increase of the rotating speeds, multi-stage protection of the part is achieved, the machining efficiency is high, and the machining cost is low. The service life of the center is prolonged, and the defect rate of products is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a numerically controlled machine tool with a clamping top. Background technique [0002] The tip is a machine tool part in mechanical processing. It has a small outer diameter and a small interference knife. It is suitable for high-speed rotating parts processing and clamping equipment. When the part is not allowed or cannot be drilled and fixed, the tip can facilitate the clamping and fixing of the workpiece. . [0003] The existing tops processed by CNC machine tools have the following technical defects in use: when the tops are fixed and supported on the parts to be processed, the notches at the bottom of the workpiece and the protrusions on the tops are engaged with each other. In the process of high-speed machining, the clamping force cannot be kept constant, and the torque transmission efficiency is poor, which affects the machining efficiency of workpiec...
