Novel propeller pitch measuring instrument

Abstract

The invention discloses a novel propeller pitch measuring instrument. The novel propeller pitch measuring instrument comprises an upper fixed plate and a supporting machine; and installing boxes are installed on the left side and the right side of the top end of the upper fixed plate, penetrating connecting sliding ways are arranged on the front wall of the upper fixed plate in a penetrating mode,connecting pillars are installed at the inner ends of the penetrating connecting sliding ways, and load-bearing mechanisms are connected to the lower end of the upper fixed plate. According to the novel propeller pitch measuring instrument, two central amplification devices can be adjusted in a transmission mode by rotating two position adjusting screws, the central amplification devices performsliding adjustment at the outer end of a supporting platform, the two position adjusting screws are rotatably used, the two central amplification devices can be adjusted and controlled, the central amplification devices fit clamping grooves on the middle parts of a propeller, and the function that the propeller is positioned is achieved; and bearings rotate, the positions between the bolt bottomsand the bolt tops can be rotatably adjusted, the bolt tops are convenient to fold, the function of reducing the vertical occupied spaces of the position adjusting screws is achieved, and the portability property of the propeller is improved.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a novel propeller pitch measuring instrument. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or similar to a helical surface. A propeller, in which a measuring instrument is generally used in the propeller to measure the distance between the propellers. [0003] The measuring devices on the market are not equipped with a relatively flexible adjustment mechanism, which leads to the problem of inconvenient mobilization of the device during the measurement work, and the cost of general instruments is also very expensive, and there is a problem of not being economical. Therefore, we propose a new type of propeller pitch measuring instrument. Contents of...
