Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The rotating spindle electromagnetic brake device of the present invention has a structure such as figure 1 Shown, including braking part, excitation power supply and measurement and control part. The braking part includes a high-permeability electromagnetic brake disc 3 and a DC electromagnet 5 arranged on the main shaft 2. The main shaft 2 is also connected with a motor 1 and a coupling 4. The brake disc 3 is located at the two magnetic poles 12 of the DC electromagnet 5. Between them, they are not in contact with the DC electromagnet 5, and the positions of the shaft coupling 4 and the motor are respectively located on both sides of the brake disc 3. Two identical cylindrical magnet protruding blocks are arranged symmetrically on the right side of the brake disc 3 to detect the spindle speed. The size of the protruding blocks is de...

Abstract

The invention discloses an electromagnetic braking device for a rotary main shaft. The electromagnetic braking device comprises a braking part, an excitation power supply and a measurement and control part, wherein the braking part comprises a high-magnetic-conductive electromagnetic braking disc and a DC electromagnet which are arranged on the main shaft, the main shaft is further connected with a motor and a coupler, the braking disc is arranged between two magnetic poles of the DC electromagnet and is not in contact with the DC electromagnet, and the coupler and the motor are respectively arranged on both sides of the braking disc; and two identical cylindrical magnet protruding blocks are symmetrically arranged on the right side end surface of the braking disc. The electromagnetic braking device for rotary main shaft solves the problems that the traditional electromagnetic braking device has great electromagnetic loss, high temperature rise, cannot operate for a long time, cannot be applied to high-speed main shaft equipment and the like.
