This invention discloses a gas turbine cylinder block machining positioning device, belonging to the field of machining clamping technology. The gas turbine cylinder block includes an outer cylinder, an inner cylinder, a star-shaped support, and a support ring. Multiple height-adjustable support mechanisms include support seats and movable supports. The movable supports are provided with normal positioning parts and tangential positioning parts. The top protection mechanism includes a guide plate, a first variable diameter plate, multiple sector plates, and multiple second positioning parts that can move synchronously radially. The guide plate is provided with multiple first straight grooves and second straight grooves. The first variable diameter plate is provided with multiple first arc-shaped grooves and connected to a second drive assembly. The multiple sector plates are stacked, and the sector plates are provided with first pins that cooperate with the first straight grooves and first arc-shaped grooves and second pins that cooperate with the second straight grooves. This invention uses height-adjustable support mechanisms to position the outer cylinder, resist shear force and axial force, and ensure support rigidity. It also cooperates with the top protection mechanism to make the axes of the support ring, outer cylinder, and inner cylinder collinear.

The utility model relates to the technical field of rice spraying machines, and discloses a novel rice spraying machine which comprises an unmanned aerial vehicle body and a liquid storage tank, the liquid storage tank is arranged at the lower end of the unmanned aerial vehicle body, buckle rods are fixedly connected to the periphery of the lower end of the unmanned aerial vehicle body, and buckle frames are slidably connected to the two sides of the upper end of the liquid storage tank. The upper end of the liquid storage tank is rotatably connected with a bidirectional lead screw, the outer surface of the bidirectional lead screw is in threaded connection with the middles of the two buckle frames, one end of the bidirectional lead screw is fixedly connected with a rotary knob, and one ends of the four buckle rods are connected with the two ends of the two buckle frames in a clamped mode. When the liquid storage tank and the unmanned aerial vehicle main body are connected and fixed, the buckle frame and the buckle rod are controlled to be clamped together by rotating the knob, the installation work of the device can be completed, and the device is more convenient and faster in the subsequent use or disassembly process; and the time of early-stage preparation work and subsequent disassembly work of the device is greatly shortened.
