The invention provides a rotary conveying platform and logistics conveying equipment, and relates to the technical field of logistics conveying. The rotary conveying platform comprises a rotating mechanism and a V-shaped conveying mechanism; the V-shaped conveying mechanism is used for conveying cylinder conveying pieces; the rotating mechanism drives the V-shaped conveying mechanism to convey toan appointed position; and the rotating mechanism realizes rotation of the V-shaped conveying mechanism in different positions of 0-360 degrees, so that the technical problem of incapability of conveying the cylinder conveying pieces after rotation in the prior art is solved.

The invention relates to pressure meter assembling equipment. A pressure meter is conveyed below a mounting mechanism by a feeding mechanism; a clamping lifting cylinder of the mounting mechanism drives a lifting connection plate to move up and down on a lifting slide rail, a cam is driven to lift, the cam is descended to drive a meter clamping lever to clamp the pressure meter, the cam is ascended to drive the meter clamping lever to loosen the pressure meter, firstly, the meter clamping lever is loosened, a lifting mechanism drives the mounting mechanism to move downwards to clamp the pressure meter, the feeding mechanism returns back to the initial position, then a rotary mechanism is moved to drive a pressure meter seat to move to a place below the mounting mechanism, a compressing mechanism clamps the pressure meter seat, the mounting mechanism is driven by the lifting mechanism to move downwards, and when the pressure meter reaches a place above the pressure meter seat, the mounting mechanism is driven to drive a rotary spindle to rotate, so the pressure meter is rotated and descended to be screwed into the meter seat, and when the torsion achieves a certain value range, the pressure meter stops rotating. The assembly of the pressure meter is full-automatically performed, the labor intensity of operation staff is reduced, and the production cost is reduced.

The invention discloses a control system and a control method of a rotary positioning platform under a microscope. The system includes: a rotary console, first and second translation consoles, a sample stage, a visual feedback subsystem, a driver, and a double closed-loop positioning Control system, the movement directions of the first and second translation consoles are perpendicular to the rotation axis of the rotary console; the double closed-loop positioning control system includes: the external position controller calculates the input displacement of the inner ring; the first and second translation control The displacement closed-loop control subsystem of the table includes: the plug-in repetitive controller calculates the displacement compensation control quantity according to the error between the input displacement and the feedback displacement; the original closed-loop displacement control subsystem calculates the displacement control quantity according to the error between the input displacement and the feedback displacement , and combined with the displacement compensation control amount to control the driver to drive the displacement of the first and second translation consoles. Improve the rotational positioning accuracy of micro-nano-scale samples under the microscope, and greatly improve the microscopic imaging effect of the sample.

The invention relates to an automatic changing device of a grinding wheel and a grinding wheel cover of a vertical internal and external grinding machine, wherein a body shell is fixed on a machine body, a servo motor is installed below the body shell, an output shaft of the servo motor is connected with an input shaft of a speed reducer through a transmission shaft located in the body shell, and the output shaft of the speed reducer is connected with a grinding wheel mounting disk; a rotating shaft is installed in the grinding wheel mounting disk; the upper end of the rotating shaft is connected with a grinding wheel cover mounting disk through a clutch, the clutch is connected with a cylinder piston rod through a guide sleeve and a guide shaft, a cylinder is fixedly connected with a clutch shell through a cylinder seat, and a spring is installed between the clutch shell and the grinding wheel cover mounting disk. According to the automatic changing device provided by the invention, the grinding wheel and the grinding wheel cover of the vertical internal and external grinding machine can be changed automatically; the operation of changing a grinding wheel turntable and a grinding wheel cover turntable is switched by the clutch, and the operations can not interfere each other during the changing process; the clutch is controlled by the cylinder and the spring; and the mechanism is driven by a numerical control servo motor, and the rotating and locating precision of the grinding wheel and the grinding wheel cover are high.
