Abstract
The invention discloses a blade torsion angle measuring tool which comprises a frame, an angle dial, a horizontal pointer, a push rod and the like, wherein the horizontal pointer is rotatably arranged on the frame, the horizontal pointer is controlled by an internal water column to be always in a horizontal position, an ejector rod wing section block is matched with a blade section 0-degree position, the blade section is rotated by the same angle as the frame and the dial during measurement, and the horizontal pointer is always in the horizontal position, so that the blade section angle is read. The invention is simple and convenient, and has good effect in the use process.
Description
Technical field:
the invention relates to the field of propeller appearance detection.
The background technology is as follows:
the shape of the propeller must be checked after the propeller is produced, wherein the most important factor affecting the aerodynamic force of the propeller is the installation angle of the blade profile.
The invention comprises the following steps:
the invention aims to: the device is convenient and quick to position the blade and can continuously measure the torsion angle of the blade surface along the blade surface.
The technical scheme is as follows: the blade torsion angle measuring tool comprises a fixed frame, a push rod, a horizontal pointer and an angle dial; the left and right rims of the frame are respectively provided with a blade front edge bracket and a blade rear edge bracket for bearing the blades; the ejector rod is in threaded fit with the top frame of the frame, and the lower end of the ejector rod is used for tightly pushing the leaf surface on the front edge bracket and the rear edge bracket of the leaf; the angle dial is fixed on the frame, the horizontal pointer is rotatably arranged on the frame, and the horizontal pointer is used for indicating the angle of the angle dial; the horizontal pointer is a strip-shaped closed transparent shell, and bubble-carrying liquid is sealed in the transparent shell to form a horizontal bubble structure; when the blade leading edge support and the blade trailing edge support are in the same horizontal position, the horizontal pointer is in the initial position or the zero scale position of the dial.
Further, a metal falling body is fixed at the center point of the horizontal pointer, so that the pointer is always in a horizontal state. Furthermore, the metal pendant is pendulum-shaped.
Further, the blade leading edge bracket and the blade trailing edge bracket are respectively matched with the blade leading edge and the blade trailing edge in a shape.
Further, a pressure head is arranged on the lower end face of the ejector rod, and the lower end face of the pressure head is matched with the cambered surface profile of the leaf surface.
Further, a rotary handle is arranged at the upper end of the ejector rod.
Fixing the blade, fixing the position of the measured section of the blade on the frame, pressing the frame by using the ejector rod, fixing the frame, reading the angle of the pointer pointing to the dial, and obtaining the torsion angle of the currently clamped position of the measured section.
The technical effects are as follows:
the invention has the advantages of convenient use, convenient reading of torsion angle and simple operation. The level gauge.
