The present invention proposes a guide wire delivery device for vascular intervention surgery, comprising two fixed supports arranged opposite to each other, a horizontal guide column arranged between the two, a guide wire delivery unit slidably connected to the horizontal guide column, the guide wire delivery unit comprising a sliding frame, a vertical guide column arranged on the sliding frame, an upper and a lower wire pressing conveying mechanism used in cooperation with each other arranged on the vertical guide column, the upper and / or lower wire pressing conveying mechanism can move along a preset track of a rectangle under the action of a driving mechanism, when moving along the two vertical sides of the rectangle, the upper and / or lower wire pressing conveying mechanism moves along the vertical guide column, when moving along the two horizontal sides of the rectangle, the upper and / or lower wire pressing conveying mechanism drives the sliding frame to move along the horizontal guide column; when moving to the left along the horizontal guide column, the two wire pressing conveying mechanisms cooperate to clamp the guide wire to achieve delivery, and when moving to the right along the horizontal guide column, the two wire pressing conveying mechanisms are in a state of releasing the guide wire. The above device can realize linear wire feeding and there is no phenomenon of the guide wire coming out during the wire feeding process.

The present invention proposes a translational wire feeding mechanism of a vascular intervention robot, including a wire pressing and conveying mechanism and a guide wheel mechanism used in conjunction with the same. The wire pressing and conveying mechanism can move in the left and right directions under the action of a first driving mechanism. When the guide wheel mechanism and / or the wire pressing and conveying mechanism are acted upon by an extrusion mechanism, the guide wheel mechanism and the wire pressing and conveying mechanism can move so that the guide wheel mechanism and the wire pressing and conveying mechanism cooperate to clamp the guide wire. When the wire pressing and conveying mechanism moves to the right / left, the guide wheel mechanism and the wire pressing and conveying mechanism continue to clamp the guide wire. Translational wire feeding can be achieved by cooperating between the wire pressing and conveying mechanism and a rotatable guide wheel in the guide wheel mechanism. When the wire pressing and conveying mechanism moves to the left / right, the guide wheel mechanism and / or the wire pressing and conveying mechanism are no longer acted upon by the extrusion mechanism. The guide wheel mechanism and / or the wire pressing and conveying mechanism that have been squeezed can be reset by a reset mechanism. The above-mentioned translational wire feeding mechanism can realize the function of translational wire feeding. Since the contact area of ​​the pressure plate is large, there is no phenomenon of the guide wire coming out during the wire feeding process.

The invention discloses a self-leveling wind power blade end face milling machine which comprises an inner ring, an outer ring and a rotating arm, the inner ring is rotationally arranged in the outer ring, the rotating arm is fixed to the front end face of the inner ring in the diameter direction of the inner ring, a milling assembly and a laser range finder are arranged on the rotating arm, and a positioning magnetic attraction assembly is arranged on the rear end face of the inner ring. A main supporting leg is arranged on the periphery of the outer ring and comprises a first telescopic rod, the first telescopic rod is connected with a worm gear and screw lifter through a servo motor so that the first telescopic rod can stretch out and draw back in the radial direction, and a sliding assembly is arranged on one side of the first telescopic rod and comprises a first sliding rail connected with the first telescopic rod; a first ball screw is arranged in the first sliding rail, a first sliding seat is arranged on the first sliding rail, and the first sliding seat is fixedly connected with a first supporting plate supported on the inner surface of the blade. The self-leveling wind power blade end face milling machine is high in safety and high in adjusting precision, meanwhile, it is guaranteed that the end face has good planeness and smoothness, and blades of different specifications can be machined.

The present invention proposes a translational wire feeding mechanism of a vascular intervention robot, comprising a first wire pressing and conveying mechanism and a second wire pressing and conveying mechanism used in cooperation with each other, wherein the first crank-connecting rod mechanism can move the first wire pressing and conveying mechanism along a preset trajectory under the action of a corresponding driving mechanism, and the second crank-connecting rod mechanism can move the second wire pressing and conveying mechanism along a preset trajectory under the action of a corresponding driving mechanism, and the movement trajectories of the first wire pressing and conveying mechanism and the second wire pressing and conveying mechanism both include a curved segment and a substantially straight segment, and when the first wire pressing and conveying mechanism and the second wire pressing and conveying mechanism simultaneously move to the substantially straight segment trajectory, the two cooperate with each other to clamp the guide wire to achieve translational wire feeding. The above-mentioned translational wire feeding mechanism can achieve horizontal movement of the wire pressing and conveying mechanism through the crank-connecting rod mechanism, and since the contact area of ​​the pressure plate in the wire pressing and conveying mechanism is relatively large, there is no phenomenon of the guide wire coming out during the wire feeding process.

The utility model discloses a cup set anti -backoff device of mixer, including cup set, anti -backoff rod and elastic part, cup set includes mixing cup and cup seat, and the lower part of mixing cup is fixedly connected through the mode of thread or along one direction rotation jointing with cup seat, and the anti -backoff limiting portion is formed on mixing cup, and anti -backoff rod is installed on cup seat through elastic part, and when cup set leans against mixer host computer, anti -backoff rod is lifted under the action of external force, and its side leans against the side of anti -backoff limiting portion to restrict mixing cup and cup seat from separating, when cup set leaves mixer host computer, anti -backoff rod leaves the side of anti -backoff limiting portion under the action of elastic part, and mixing cup and cup seat can normally separate. The utility model adopts the mode that anti -backoff rod leans against the side of anti -backoff limiting portion to limit and prevent the anti -backoff between mixing cup and cup seat, and the anti -backoff mode is stable, improves the stop effect of cup set anti -backoff device, and guarantees the safety of practical mixer.
