Description

technical field [0001] The invention relates to a linear vibrating mechanism, more specifically, to a linear vibrating device for electrolytic machining. Background technique [0002] In the technical field of machining, a linear reciprocating mechanism is often required. For example, in electrolytic machining, the spindle of the electrolytic machining machine usually needs to drive the cathode tool to move up and down to perform electrolytic machining. There are many types of existing linear motion mechanisms, such as linear motors, cylinders, oil cylinders, and rack-and-pinion mechanisms, crank-slider mechanisms, or screw-nut mechanisms to convert the rotational motion of the motor into linear motion. Compared with cylinders and oil cylinders, linear motors have lower dynamic rigidity and cannot play the role of buffering and damping. Air cylinders and oil cylinders need to be equipped with air pressure and oil pressure systems, resulting in complex equipment structures....
