摘要： Disclosed is a method for grinding a spring with high quality and high efficiency, comprising the steps as follows: firstly, at least one of an upper grinding wheel (1) and a lower grinding wheel (2) is configured to comprise an inner grinding wheel (21) and an outer grinding wheel (24), wherein the inner grinding wheel (21) is fitted in the outer grinding wheel (24); the inner grinding wheel (21) or the outer grinding wheel (24) is driven by a transmission mechanism, the inner grinding wheel (21) and the outer grinding wheel (24) rotating in opposite directions; after a complete spring is fed to a space between the upper grinding wheel (1) and the lower grinding wheel (2), the complete spring is moved back and forth in the plane of the grinding wheels; and then the upper grinding wheel (1) is moved downwardly such that two end faces of the spring are ground by the grinding wheels, and when the height of the ground spring meets the requirement, the upper grinding wheel (1) is stopped moving downwardly and is returned to the original point later. Then, the ground spring movement is stopped and it is moved away from the space between the two grinding wheels, i.e., the complete spring is removed. In this way, the spring is ground in a revolving state, which can improve the yield and quality of ground springs, save energy and protect the environment, and result in a low cost of grinding, a simple structure, low cost for manufacturing parts, long persistence in precision of mechanisms, and good stability.

摘要： Electromechanical knocking device and knocking method for working, smoothing and cold-hardening the surface of tools, machine parts and other parts by hammering an impact head onto the surface of the said parts by means of mounting them on a machine tool or a robot. The impact head (1a) is fastened to a support (1b), which has a ferromagnetic part (1c). A magnetic field (B1) keeps the support of the impact head in a defined position of rest. On the support of the impact head (1b) there is at least one coil (4), which is located in the first-mentioned magnetic field (B1) or another magnetic field (B2) and is flowed through by an alternating current or pulsed current (12) with or without a variable direct current component. As a result, the impact head (1a) is made to undergo oscillations with a defined impact frequency, impact amplitude and zero crossing. The combination of this device with an analytical CAM system makes it possible for any three-dimensional workpiece surfaces to be worked with allowance for the geometrical and material-related technical data as well as local dimensional and positional tolerances as a control unit or a fully automatic control system.
