Description

Technical Field

[0001] This utility model relates to the calibration of large-size outside micrometers, specifically to an auxiliary device for calibrating large-size outside micrometers. Background Technology

[0002] Large-size outside micrometers with a measuring range of (1000 - 3000) mm are indispensable precision measuring tools for inspecting large workpieces. Regular calibration of large-size outside micrometers is crucial for ensuring product quality and process accuracy. Due to their large size, weight, and the long measuring rod used in the calibration process, the calibration usually requires the cooperation of multiple metrology professionals. This not only significantly impacts calibration efficiency but also introduces many uncertainties, leading to low calibration efficiency and unstable calibration results. Therefore, it is essential to design an auxiliary device for calibrating large-size outside micrometers that is simple in structure, easy to manufacture, convenient to operate, and can guarantee calibration accuracy. Utility Model Content

The fixed frame comprises a pair of separately arranged bases, a support mechanism, a first U-shaped support frame, and a second U-shaped support frame. The support mechanism includes a pair of lower horizontal tubes, a pair of upper horizontal tubes, and three pairs of vertical tubes. The two ends of the lower horizontal tubes are connected to the bases, and adjustment grooves are provided on the lower horizontal tubes. The bottom of the first U-shaped support frame is located within the adjustment grooves and can slide along the adjustment grooves. The second U-shaped support frame is mounted on a pair of vertical tubes located at the edge of the frame and includes an adjustment mechanism. The knob has a lead screw, support head, fixing bolt, limit stop, trapezoidal slider and main frame. The cantilever ends of the lower and upper horizontal tubes are provided with through-hole threaded assemblies. The movable frame includes a base, a support column and four horizontal tubes. The support column is fixed on the base. A third U-shaped support frame is provided on the support column. The horizontal tubes are provided with one or more through holes. The horizontal tubes are inserted into the lower and upper horizontal tubes respectively and fixed by the through-hole threaded assemblies and the through holes. The first U-shaped support frame, the second U-shaped support frame and the third U-shaped support frame form a micrometer station for calibrating the outer diameter of the larger size.

[0006] Furthermore, the number of through holes is 10-15.
