Description

Technical Field

[0001] This utility model relates to the field of electromagnetic chuck technology, specifically to an electromagnetic chuck with anti-shake function. Background Technology

[0002] Electromagnetic chucks generally refer to electrically controlled permanent magnet chucks. Electrically controlled permanent magnet chucks are a new type of clamping device designed and developed by combining electromagnetic and permanent magnet characteristics. They are new magnetic chucks that use electrical pulses to "on and off" and are widely used in CNC machining centers, milling machines, engraving machines, etc.

[0003] When using existing electromagnetic chucks, they are usually placed directly on the processing table. However, due to the material of the electromagnetic chuck, its bottom is relatively smooth, which causes the workpiece to shake during processing, leading to workpiece failure. In addition, existing electromagnetic chucks often have connecting wires, which may be too long and easily trip the operator, thus causing problems in workpiece processing. Utility Model Content

A screw is rotatably installed between the partition and the inner surface of the square groove. A sleeve plate is threaded onto the outer surface of the screw. A horizontal plate is fixedly installed on one side of the sleeve plate. The horizontal plate movably passes through the partition. A compression plate is fixedly installed on one side of the horizontal plate. A rubber ball is fixedly installed on the side of the compression plate away from the horizontal plate. Several rubber balls are arranged in an array on one side of the compression plate. Several semi-circular notches are formed on the outer surface of the turntable. Several semi-circular notches are arranged in a ring array on the outer surface of the turntable. The rubber balls are movably fitted to the side of the electromagnetic chuck body.
