Abstract: A self-rotation cleaning device has outer and inner housings, a workpiece rotating system, an ultrasonic cleaning system and a fluid perfusion system. The inner housing is in the outer housing in a horizontal direction. A cylindrical cavity is inside the inner housing. One end of the inner housing has a sealing cover detachably connected thereto, and the other end is closed. The workpiece rotating system is in the cavity for fixing a member to be cleaned, and realizes self-rotation of the member. The ultrasonic cleaning system supplies mechanical energy to the cleaning liquid in the inner housing to generate bubbles therein. The bubbles remove residual resin attached to the cleaned member surface by continuous vibration and burst. The fluid perfusion system provides self-rotation power for the cleaned member, and continuously delivers the cleaning liquid to the inside of the cleaned member, and the cleaning liquid is carried out after cleaning.

Abstract: A BTA drilling quick-stop device (QSD) and a method, wherein the BTA drilling QSD includes a base. The base includes a hollow cavity. A side portion of the base has an opening communicating with the hollow cavity. The opening is closed by a through cover. A horizontally movable fixture is disposed in the hollow cavity. A stopper is disposed at a top portion of the base. A bottom portion of the stopper is disposed lower than a top portion of the fixture to stop the fixture from moving during processing. An elastic element is disposed between the through cover and a side portion of the fixture to push the fixture to move after processing.

Abstract: The invention relates to a hydraulic system, method, and integrated valve block for a slewing mechanism, comprising a first and second cylinder. The rod cavity of the first cylinder connects to the rodless cavity of the second cylinder through the first oil circuit, first hydraulic control check valve, and fourth oil circuit. The rodless cavity of the first cylinder connects to the rod cavity of the second cylinder through the second oil circuit, second hydraulic control check valve, and third oil circuit. The first oil circuit is connected to the directional valve through the sixth oil circuit, and the second oil circuit is connected to the directional valve through the fifth oil circuit. The directional valve is connected to the hydraulic pump and oil tank. The first hydraulic control check valve is installed between the first and fourth oil circuits, and the second hydraulic control check valve is between the second and third oil circuits. The check valves' control circuits connect to the sixth oil circuit, ensuring braking stability of the slewing mechanism.

Abstract: A method and system for calculating a primary shear zone stored energy field during steady-state cutting, the method including: fitting parameters of a workpiece material stored energy evolution model; discretizing the primary shear zone into infinitesimals on a main shear plane. The infinitesimals are small enough, a strain, strain rate, and temperature are assumed constant; introducing an equivalent cutting edge model simplifying three-dimensional cutting into two-dimensional cutting, calculating element strain and strain rate using a shear plane model, and analyzing element temperature using a heat conduction equation; deriving a differential equation of stored energy versus location in the primary shear zone using stored energy evolution, strain rate distribution, strain distribution, and temperature distribution models; and solving the differential equation for each infinitesimal using an initial shear plane as a model boundary, obtaining stored energy at each location to obtain a stored energy field distribution of the primary shear zone.
