SQ-Ⅰ millimeter value calibrator

1. Overview:
The micrometer indicator calibrating instrument is an instrument with a lever spiral compound structure. It is used to calibrate the indication error and return error of the inner diameter micrometer and lever micrometer. It is one of the necessary calibration equipment for metrological verification institutes and industrial and mining measurement rooms.
2. The principle structure of the millimeter value calibrator:
The principle of the millimeter value calibrator is to convert the angular displacement of the screw into the linear displacement of the measuring rod with the help of the screw pair-lever transmission. A high-precision mechanical instrument.
. Differential drum. Differential screw. Nut. Lever. Lever fulcrum. Linear displacement measuring rod. Dial indicator
As shown in the figure, when the drum is rotated, the differential screw will move left and right in the horizontal direction. It forces the lever mechanism to rotate with the lever fulcrum as the center and drives the linear displacement measuring rod to move vertically up and down, directly pushing the dial indicator measuring rod to move, which plays a role in verifying the millimeter value error and return error.
The dimensions and data of the millimeter value calibrator are as follows:
