Embodiment Construction

[0021] Taking the application of the present invention to measure the opening angle of the valve in the casing and the valve structure as an example, the present invention will be further described in detail.

[0022] Such as figure 1 As shown, the tested part is composed of a fixed part and a rotating part, and the rotating part is fixed on the fixed part through the rotating shaft; that is, the tested part is a casing and a valve structure, the fixed part is the casing, the rotating part is the valve, and the valve passes through The rotating shaft is fixed on the casing. When working, the valve 10 is opened around the rotation axis 2 from the N2 closed state to the N1 open state. It is necessary to measure the angle 0°, 3°, 6° of the valve 10 from the N2 closed state to the N1 open state. .

[0023] Such as figure 2 , image 3 As shown, an angle detection gauge includes a fixing device 5, and one end of the fixing device 5 is connected to a screw rod 6 through threads....

Abstract

The invention discloses an angle detection tool and a detection method thereof and belongs to the technical field of angle detection. The angle detection tool is simple and convenient to operate and low in cost. Components are irregular in shape and need measuring continuously in narrow and small space, and rotation angles of two components are measured in specific conditions of rotation around a fixed shaft and the like. The angle detection tool comprises a fixing device, and one end of the fixing device is connected with a screw through threads. The detection method using the angle detection tool includes that the fixing device is fixed on a fixing part of a measured component, so that the screw at one end of the fixing device is vertical to the upper surface of the fixing part of the measured component; the screw is rotated, so that the end portion of the screw is contacted with the rotating part of the measured component; the stretched length of the screw and the distance between the screw and a rotation shaft are read; and an included angle between the rotating part and the fixing part is determined according to an arc-tangent function.

Description

technical field [0001] The invention belongs to the technical field of angle measurement, in particular to an angle detection gauge and a detection method thereof. Background technique [0002] In the engine industry, the structure of the parts is relatively complex, and the assembly is also difficult. It is also quite difficult for the process that needs to be measured during the assembly process. For two parts to be assembled together and rotate around a fixed axis, there are many ways to continuously measure the rotation angle between the two parts. Angle tracking measuring instruments, angle rulers, etc. can be used, but the space required is large, and the The surface shape of the parts also has certain requirements. [0003] For parts with complex structure, narrow measurement space, and the outside of the part is blocked, the angle of rotation of the connected parts around the fixed axis is continuously measured; when the two parts are fitted together, it is zero deg...
