The invention relates to the technical field of tool turrets, in particular to a built-in motor direct-drive-force tool turret, the tool turret adopts a direct-drive motor design, complex mechanical transmission parts are omitted, after simplification, the failure rate is reduced, the maintenance cost is remarkably reduced, the service life of equipment is prolonged, meanwhile, module cooperation of a sensing detection assembly is adopted, and the tool turret is convenient to use. The rotating speed of the tool turret in the machining process can be met through the single driving motor, the rotating speed of the tool turret in the rotating tool changing process can also be met, and therefore the effect that the single driving motor can drive the tool turret to conduct rotating cutting machining and can drive the tool turret to conduct rotating tool changing is achieved. And meanwhile, an electric clamping and unlocking mechanism is adopted, and compared with manual tool changing operation of a traditional tool turret, the tool changing time is remarkably shortened.

The application discloses an oil-gas separation device and a control method. The oil-gas separation device comprises a labyrinth structure, a connecting pipeline and a cyclone structure. The air inlet of the labyrinth structure is connected with a crankcase. One end of the connecting pipeline is connected with the air outlet of the labyrinth structure. The connecting pipeline is provided with a control valve. The other end of the connecting pipeline is provided with two rows of outlets. The cyclone structure is provided with a first oil-gas separator and a second oil-gas separator. The first oil-gas separator and the second oil-gas separator are respectively connected with one row of outlets. The oil-gas separation efficiency of the first oil-gas separator is less than that of the second oil-gas separator. The control valve is used for controlling the opening and closing states of the connecting pipeline, the first oil-gas separator and the second oil-gas separator. According to the rotating speed of different engines and the average effective pressure of different engines, one of the first oil-gas separator and the second oil-gas separator is opened, or the first oil-gas separator and the second oil-gas separator are simultaneously opened, so that the rotating speed and the average effective pressure of different engines can be adapted.

The present application relates to a kind of high-speed boat with two skids symmetrically arranged on the bottom of deep V planing boat, the extension length and the trim angle of the skid can be adjusted, and two sets of surface propeller propulsion systems are arranged at the stern, the horizontal direction and the vertical direction of the propulsion angle can be adjusted.The present application can maintain the good seaworthiness and rapidity of deep V boat type under high sea conditions.When sailing at high speed under normal sea conditions, the lift and the upward reaction force of surface propeller on the boat body will lift the boat body out of the water, and a very high speed can be achieved.For different sea conditions, manual or automatic control mode can be selected to adjust the sailing state and speed of the boat.The present application has simple structure, small resistance and high speed when skid is sliding, and has good safety, rapidity and energy efficiency ratio under the same power;PID automatic control system is used to ensure the safety, maneuverability and rapidity of the boat;The present application provides a high-speed boat type suitable for various sea conditions for military, police and other industries.

This application relates to an electric helical rotary screw lifting structure and its control system, belonging to the field of lifting screws. It includes: a lifting shaft, comprising an internally threaded shaft and a lifting sleeve, the lifting sleeve being sleeved around the internally threaded shaft to form a screw drive for driving the lifting sleeve to rise or fall; a lifting drive assembly, equipped with a lifting drive source and a gear reducer, the gear reducer containing a worm gear and a worm for speed reduction, the worm gear being made of POM plastic and the worm being made of metal, the drive source driving the worm, the worm gear meshing with the end of the internally threaded shaft to drive the internally threaded shaft to rotate; and a lifting guide sleeve, sleeved on the outside of the lifting sleeve, with a guide protrusion fixedly provided on the inner wall of the lifting guide sleeve, and a guide groove formed on the outer wall of the lifting sleeve along the lifting direction, the guide protrusion being inserted and sliding within the inner wall of the guide groove, and the lifting guide sleeve being fixed to an external mechanism via a flange. This application has the effect of further improving the lifting efficiency of the electric screw structure and reducing noise.
