1. The working method of the excitation type three-dimensional force inner cavity deruster is characterized in that:

  • the lower part of the vibration platform is provided with a fixed support leg, and the vibration platform is connected with the fixed support leg through an elastic support leg;

    a component force bracket is arranged below the vibration platform, and a vibration motor is arranged on a component force inclined plane of the component force bracket;

    the cavity workpiece is arranged on the vibration platform, each support leg of the component force bracket is a leg with unequal height, namely the height of each support leg of the component force inclined plane is unequal, namely the included angle between the vibration platform and the component force inclined plane in the X direction is greater than zero, and the included angle between the vibration platform and the component force inclined plane in the Y direction is greater than zero;

    the cavity workpiece can be sealed by itself or a sealing cover;

    a pressing plate is arranged on the cavity workpiece, and a screw passes through a hole in the pressing plate and is screwed into a threaded hole in the vibrating platform to fix the cavity workpiece on the vibrating platform;

    filling abrasive materials into a cavity of the cavity workpiece, sealing the cavity workpiece and fixing the cavity workpiece on the vibration platform;

    because the included angle between the vibration platform and the component force inclined plane is greater than zero degree, the included angle between the vibration platform and the component force inclined plane in the X direction is greater than zero degree, and the included angle between the vibration platform and the component force inclined plane in the Y direction is greater than zero degree, the direction of the vibration force of the vibration motor and the supporting direction of the elastic supporting leg in the Z direction also form an included angle, so that the vibration force of the vibration motor is transmitted to the vibration platform from the component force inclined plane and is decomposed into Z, X, Y forces in three directions;

    the vibration platform supported by the elastic supporting legs in a free state drives the cavity workpiece to vibrate along with Z, X, Y three directions, so that the abrasive in the cavity is thrown, and the purpose of removing rust for the cavity of the cavity workpiece is achieved.
