Problems solved by technology

Since the two sides of the V-shaped caliper cannot completely fit the part when taking the corner, it will cause errors when taking the corner, which will affect the measurement accuracy. At the same time, the measurement steps are more complicated. Not only the measurement efficiency is low, but also the change of the angle cannot be reflected intuitively

Embodiment 1

[0033] Embodiment 1 A scissors-type angle measuring device

[0034] like Figure 1-Figure 6 As shown, the scissors-type angle measuring device is composed of component I (10), component II (20), positioning block (30), rotating shaft (40), sliding screw (50) and copper wire (60).

[0035] like Figure 5 As shown, one end of component I (10) is provided with a handle part I (11), and an obtuse angle reference plane (13) is provided on the handle part I (11). The middle part is provided with an angle dial (12), and an angle mark is arranged on the angle dial (12). The other end is the acute angle datum plane I (14).

[0036] like Image 6 As shown, one end of component II (20) is provided with a handle part II (21), the middle part is provided with a window (22) for reading the angle, and the two ends of the window (22) are provided with oblong sliding grooves (23). II (20) is provided with a calibration line (24) for positioning.

[0037] The positioning block (30) is ins...

Embodiment 2

[0041] Embodiment 2 An angle measurement method

[0042] Adopt the angle measuring device of embodiment 1, method is as follows:

[0043] 1) Visually measure the angle of the part to be tested;

[0044] 2) if Figure 7 As shown, if the part to be measured (70) is an acute angle, fit the two sides of the part to the acute-angle reference plane I (14) of the component I (10) and the acute-angle reference plane II (32) of the positioning block (30) respectively, and pass Window, read the angle scale corresponding to the copper wire;

[0045] 3) if Figure 8 As shown, if the part to be measured (80) is an obtuse angle, fit the two sides of the part to the obtuse reference plane I (13) of the component I (10) and the obtuse reference plane II (31) of the positioning block (30) respectively, and pass Window, read the angle scale corresponding to the copper wire.

[0046] When measuring, you can operate the two handles with one hand, clamp the positioning end on the bending edge...

Abstract

The invention relates to a scissors-type angle measuring device and an angle measuring method. The adopted technical scheme is: a handle part I is provided at one end of the component I, an angle dial is arranged at the middle part, and an angle mark is arranged on the angle dial. One end of the component II is provided with a handle part II, the middle part is provided with a window for reading the angle, sliding grooves are provided at both ends of the window, and a calibration line for positioning is provided on the component II. The positioning block is fixed with the other end of component II. The rotating shaft connects component I and component II together. The slide screw is installed on the slide groove. Both ends of the copper wire are fixed with sliding screws, and the copper wire coincides with the calibration line on component II by adjusting the sliding screws. The invention has simple structure, convenient operation and can improve measurement accuracy.

Description

technical field [0001] The invention relates to a measuring device, especially an improvement of an angle measuring device. The angle measuring method is improved according to the measurement of opening and closing angles, and belongs to the technical field of mechanical measurement. Background technique [0002] When inspecting some sheet metal parts on the aircraft, it is necessary to measure the angle between the web surface and the flange of the part at a certain cut surface. When measuring, it is usually clamped at the cut surface of the part with a V-shaped caliper, and then removed. V-shaped caliper, use a protractor to measure the angle formed by the two sides of the V-shaped caliper. Since the two sides of the V-shaped caliper cannot completely fit the part when taking the corner, it will cause errors when taking the corner, which will affect the measurement accuracy. At the same time, the measurement steps are more complicated. Not only the measurement efficiency ...
