Embodiment Construction

[0009] The structure of the scanning tunnel nanoscale precision measuring instrument of the present invention is as follows: figure 1 As shown, it mainly consists of a precision ruler (1), a depth gauge (2), an inner and outer diameter ruler (3), a caliper (4), an outer diameter pointer (5), an inner diameter pointer (6), a depth pointer (7), an outer diameter Card (8), inner diameter card (9), insulator (10), probe (11), ordered atom plate (12), power supply (13), switch (14) and computer (15). Before using the present invention, place the scanning tunnel nanoscale precision measuring instrument of the present invention on an anti-vibration system, and place the switch (14) in an off state.

[0010] When the inner diameter of a certain pipe needs to be measured, move the caliper (4) to the left so that the two inner diameter cards (9) all extend into the pipe, and then move the caliper (4) to the right to make the two inner diameter cards (9) clamp the inner wall of the pipe....

Abstract

The invention relates to a tunnel-scanning nano-level precision gauge, which is mainly formed by a precision scale (1), a depth scale (2), an inner-outer diameter scale (3), a caliber (4), an outer diameter pointer (5), an inner diameter pointer (6), a depth pointer (7), an outer diameter clamp (8), an inner diameter clamp (9), an insulator (10), a probe (11), a sequenced atom plate (12), a power supply (13), a switch (14) and a computer (15). The tunnel-scanning nano-level precision gauge comprises two steps of macroscopic measurement and microscopic measurement and obtains the measuring result by summing the measuring value obtained by the macroscopic measurement and the measuring value obtained by the microscopic measurement. The macroscopic measurement accuracy only reaches the millimeter level. The microscopic measurement needs to use the probe (11) to scan the orderly arranged atoms on the sequenced atom plate (12), the computer (15) records the number of the scanned atoms at the same time and multiplies the number by the diameter of the corresponding atom to obtain the microscopic measuring result with the nano-level precision. The tunnel-scanning nano-level precision gauge is high in precision, convenient to operate, safe and reliable.
