A CNC machine tool with clamping top

Abstract

The invention relates to the technical field of intelligent manufacturing, and discloses a CNC machine tool with a clamping top, including a base, a first bracket, a second bracket, a motor, and a grinding piece. The second bracket is located on the right side of the motor The end of the output shaft of the first bracket is fixedly connected with a shaft sleeve, the left side wall of the first bracket is fixedly connected with a limit column, the right side wall of the shaft sleeve is fixedly connected with a top sleeve, and the center of the top wall of the top sleeve is fixedly connected with a The rotation column, the circumference of the rotation column is fixedly connected with the first protrusion, and the inside of the limiting groove is slidably connected with the permanent magnet. The present invention realizes the clamping of the parts to be processed through the first protrusion on the top, realizes the multi-level switching of the protection mechanism through the centrifugal force changes at different speeds during the processing of the parts, has a high degree of automation, and keeps the torque stable according to the increase of the speed Transmission, to achieve multi-level protection of parts, high processing efficiency, improve the service life of the top, so that the defective rate of the product 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 tip. Background technique [0002] The top is a machine tool part in machining. 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 parts are not allowed or cannot be fixed, the top can facilitate the clamping and fixing of the workpiece. . [0003] The existing CNC machine tool has the following technical defects in use: when the top is fixed and supported for the parts to be processed, the notch at the bottom of the workpiece and the protrusion of the top are mutually clamped, but this way of clamping is relatively difficult. In the process of high speed processing, the clamping force cannot be kept constant, and the torque transmission efficiency is poor, which affects the processing efficiency of workpiece ...
