Calibration jig, a horizontal calibration device, and horizontal calibration method

Abstract

The present invention provides a calibration jig, a horizontal calibration device, and a horizontal calibration method. The calibration jig is configured to be mounted on the horizontal calibration device and includes: a reference platform having a plurality of through holes extending through its top surface; a plurality of extension rods, each movably inserted through a corresponding through hole and extending beyond a bottom surface of the reference platform, wherein the number of extension rods corresponds to the number of through holes; and a plurality of depth gauges, each including a probe that is in contact with a top end of a corresponding extension rod, wherein the number and positions of the depth gauges correspond to those of the through holes. By using the horizontal calibration device and method of the present invention, parallel or horizontal calibration can be performed quickly and accurately.
