The invention discloses a duplex three-gear inner gearing compound motor pump driven by a switch flux motor. A motor rotor adopts a hollow structure; a first pump body composed of a first outer gear ring, a first pinion and a first partition board and a second pump body composed of a second outer gear ring, a second pinion and a second partition board are embedded in the motor rotor; the first pump body and the second pump body adopt inner gearing compound gear pumps and are connected in parallel to form a double-pump structure; the double-pump structure adopts the manner of oil feeding at two ends and oil discharging at one end; one side of each pump body is provided with an oil feeding oil distribution disc and an oil feeding end cover; an oil discharging oil distribution disc is arranged between two pump bodies. According to the invention, the pump bodies are embedded in the switch flux motor, so that the pumping capacity is increased, the pump flow pulsation is reduced, and the characteristic of high-pressure mass flow is easy to realize to enable the working performance to be safe and stable.

The invention relates to the field of five-axis gantry machining center tools, in particular to a direct-drive high-speed five-axis gantry machining center with a replaceable milling head, which solves the problems in the prior art, such as low precision and the like. Two linear guide rails are arranged on a left bridge and a right bridge respectively; a slide plate is in slide fit with a guide rail on a crossbeam through a slide block; a ram is in transmission fit with the slide plate through double lead screws, a double-pendulum head with A and C shafts is mounted at the bottom of the ram, and a head magazine is arranged on one side of a worktable; two ends of the crossbeam are mounted on the left bridge and the right bridge through slide seats; linear motors are adopted on the X direction and Y direction of the five-axis machining center for direct driving, the crossbeam moves horizontally along the left bridge and the right bridge in the X direction, and the slide plate moves horizontally along the crossbeam in the Y direction, double motors in the Z direction of the five-axis machining center drive the ram through gravity centers, and the ram moves vertically on the slide plate in the Z direction. The machining center has stable running and performance, and is suitable for precision finishing of dies in the industries of aviation, spaceflight, automobiles, and the like.

The invention discloses a high-precision direct driven air flotation turntable, which comprises a supporting seat (1), a hoisting ring screw (2), a handle (3), a sealing ring (4), an axial throttle (5), a radial throttle (6), a mounting pedestal (7), a radial bearing outer ring (8), an O-shaped rubber sealing ring I (9), an air flotation face assembly (10), an O-shaped rubber sealing ring II (11), a pressure block (12), a motor mounting seat (13), a socket (14), a plug I (15), a plug II (16), a torque motor stator (17), a torque motor rotator (18), a small pressure ring (19), a grating disc (20), a reading head (21), a reading head bracket (22), a gland (23), a sealing plate (24) and a large pressure ring (25). The turntable has high indexing precision and low end face run-out and radial run-out, and solves the precise indexing problem under the condition of high load.

The invention provides a combined type flow valve for liquid of a high-pressure large-flow alternating current servo direct-drive machine. An alternating current servo motor drives a push rod through the transmission of a thread and the push rod acts on a hydraulic transmission cavity which is sealed with hydraulic oil; when the push rod moves, the inner volume of the hydraulic transmission cavity is changed and a valve core moves to the same side to compensate the change of the volume, so that the movement of the valve core is controlled through controlling the movement of the push rod. The valve has the advantages of simple structure, accurate control and convenience for use, can directly use a computer to carry out digital control, has good buffering and positioning performances, can meet the requirements of positioning any point, can realize a closed ring system of electric feedback, and especially can be used for better solving the problem that the previous servo valve is sensitive to oil liquid pollution. The valve is wide in working pressure range and large in flow and can work under a very low oil supply pressure, and the dynamic performance is not greatly influenced by the low oil supply pressure; and the valve has fewer middle transmission links so that the efficiency of the system can be improved.

The invention discloses an intelligent light control sun-shading system. The intelligent light control sun-shading system solves the problem that due to the fact that in daily life, a curtain can not be opened or closed in time, the indoor luminance is too high or too low. The intelligent light control sun-shading system can be automatically and manually controlled. A luminance sensor is arranged to collect luminance data, the data are transmitted to a central processing unit of an indoor control system with the help of a wireless transmission module, and whether the curtain opening and closing operation and other operation are conducted or not is analyzed according to set programs. By means of the system, under the no-man control condition, automatic opening and closing of the curtain can be controlled on the basis of the indoor light ray intensity, the good rest environment, the good reading environment, the good study environment, the good storage environment and other environments are created for indoor portions, and the more comfortable and user-friendly living experience is provided.
