Description

Instrument calibration device {INSTRUMENT CALIBRATION DEVICE}

The present disclosure relates to orthodontic devices, and more particularly, to orthodontic devices for mechanical arms.

The conventional instrument straightening device disclosed in Chinese Patent Application Publication No. 105773660 A is operable to calibrate mechanical pieces having first and second straightening blocks rotatable relative to each other. The instrument calibration device has a primary calibration piece fixed to the first calibration block, and an auxiliary calibration piece secured to the second calibration block. The primary calibration piece is provided with a positioning notch, and the secondary calibration piece is provided with a calibration notch aligned with the positioning notch in the primary calibration piece. The calibration device further comprises a plug piece that can be simultaneously plugged into the positioning notch and the calibration notch to achieve the purpose of calibration. The positioning notch and the calibration notch must be properly aligned so that the plug piece is plugged through it, so that the primary and secondary calibration pieces must be precisely manufactured with notch dimensions that match the dimensions of the plug piece. However, due to possible manufacturing and assembly errors, the notch dimensions may deviate and the plug piece may not fit through it.

Another conventional instrument straightening device disclosed in Japanese Patent Application Publication No. 2013006242 A corrects a mechanical piece having a base and a mechanical arm rotatably connected to the base. The mechanical arm is integrally molded with the first mark, and the base is integrally molded with the second mark. The user can also check if the mark is visually linked for calibration, but to obtain a more precise calibration, a control program is used that requires additional motors and programming algorithms to achieve small calibration movements, thus costing the entire calibration process. It costs a lot.
