[0025] Example 1
[0026] A self-positioning high-precision aperture measuring device includes a bracket 1, a coarse adjustment knob 2, an adjustable support arm 4, a measuring rod 5, and a self-positioning structure 6. There are two adjustable support arms 4 and measuring rods 5. An adjustable support arm 4 and a measuring rod 5 are respectively provided at both ends of 1, a self-positioning structure 6 is provided outside each adjustable support arm 4, and a thick knob is provided on the housing of the support 1. The bracket 1 is provided with a sliding groove; the coarse adjustment knob 2 is located in the center of the bracket 1, and under the coarse adjustment knob 2 is a high-precision straight / helical gear 8, which can be unlocked and locked by pulling up and pressing down.
[0027] An electronic module can also be installed on the shell of the bracket 1, which can realize μ-level high-precision ranging, and can display the measured value and the percentage of power in real ...

[0029] Example 2
[0030] Such as figure 1 As shown, a self-positioning high-precision aperture measuring device includes a bracket 1, a coarse adjustment knob 2, an adjustable support arm 4, a measuring rod 5, and a self-positioning structure 6. The device uses horizontal and vertical damping rods and The coordinated movement of the universal ball reaches the state of force balance, ensuring that the measured length direction is in the diameter direction of the radial tangent circle. The linear grating ruler is used to realize the rapid and accurate measurement of the aperture. The device needs to be used in conjunction with the outer diameter micrometer.
[0031] Coarse adjustment knob 2 includes: coarse adjustment knob 2, high precision straight / helical gear 8;
[0032] Adjustable arm 4 includes: adjustable arm 4, arm straight / oblique rack 7;
[0033] Self-positioning structure 6 includes: horizontal damping rod 10, horizontal universal ball 11, vertical universal ball 12, vertical...
