Abstract
The invention discloses a kind of blade torsional angle measuring tools, this patent is made of frame, angle scale, horizontal pointer, mandril etc., the horizontal pointer is rotatably arranged on frame, horizontal pointer is in a horizontal position always by the control of internal water column, mandril aerofoil profile block and 0 degree of blade section location matches, blade section and frame, scale disc spins equal angular when measurement, horizontal pointer is in horizontal always, to read blade section angle.The present invention is simple and convenient, obtains good result in use.
Description
Technical field:
The present invention relates to propeller profile measurement fields.
Background technique:
Its shape must be checked after the completion of propeller production, wherein it is aerodynamic most important to influence propeller
Factor is the established angle of propeller-blade section, and this patent is a kind of measuring tool of the measurement propeller blade torsional angle of simple and convenient.
Summary of the invention:
Goal of the invention: providing a kind of conveniently locating blades, and blade face torsion can be continuously measured along blade face
The device of angle.
Technical solution: a kind of blade torsional angle measuring tool, the measuring tool include fixed frame, mandril, horizontal pointer and angle scale；Institute
It states and is respectively arranged with blade inlet edge bracket and trailing edge bracket on frame left and right side frame, for carrying blade；The mandril
It is threadedly engaged with frame top frame, mandril lower end is used to blade face holding out against edge bracket in front of the blade and trailing edge bracket；It is described
Angle scale be fixed on frame, the horizontal pointer is rotatably arranged on frame, and horizontal pointer is used to indicate angle
The angle of scale；The horizontal pointer is strip Shape closed transparent shell, and band bubble liquid is sealed in transparent shell, is constituted
Horizontal bubble structure；When blade inlet edge bracket and trailing edge bracket are in the same horizontal position, horizontal pointer is in dial
Initial position or zero graduation position.
Further, the horizontal pointer central point is fixed with metal falling body, so that pointer is in horizontality always.More
Further, metal falling body is pendulum shape.
Further, the blade inlet edge bracket and trailing edge bracket cooperate respectively at blade inlet edge and rear shape.
Further, the mandril lower end surface is provided with pressure head, pressure head lower end surface and blade face cambered surface positive.
Further, the mandril upper end is equipped with rotating handle.
Blade is fixed, the measured section position of blade is fixed on frame, and is compressed with mandril, by frame into
Row is fixed, and reading pointer is directed toward the angle of dial, obtains the windup-degree of the measured section position of existing clamp.
Technical effect:
The present invention is easy to use, and windup-degree reads convenient and easy to operate.The level meter.
Detailed description of the invention:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is another structural schematic diagram of the present invention；
Wherein: 1- fixed frame, 2- mandril, the horizontal pointer of 3-, 4- angle scale, 5- metal falling body.
Specific embodiment:
A kind of blade torsional angle measuring tool is provided, which includes fixed frame 1, mandril 2, horizontal pointer 3 and angle scale 4；Institute
It states and is respectively arranged with blade inlet edge bracket and trailing edge bracket on frame left and right side frame, for carrying blade；The mandril
It is threadedly engaged with frame top frame, mandril lower end is used to blade face holding out against edge bracket in front of the blade and trailing edge bracket；It is described
Angle scale 4 be fixed on frame, the horizontal pointer is rotatably arranged on frame, and horizontal pointer is used to indicate angle
The angle of scale；The horizontal pointer is strip Shape closed transparent shell, and band bubble liquid is sealed in transparent shell, is constituted
Horizontal bubble structure；When blade inlet edge bracket and trailing edge bracket are in the same horizontal position, horizontal pointer is in angle scale
Initial position or zero graduation position.
