Problems solved by technology

However, due to the large magnification of the secondary element measuring instrument, the electronic device needs to be moved when the secondary element measuring instrument measures large-scale features. The reference standards of the electronic device are different before and after the movement, which reduces the measurement accuracy.

Abstract

The application provides a measuring fixture. The measuring fixture includes a fixed plate, a working plate and a supporting mechanism. The fixed plate is used to fix the measuring fixture; the working plate and the fixed plate are hinged; Electronic devices of different sizes; wherein, when the working plate rotates around the fixed plate, the electronic device fixed by the holding mechanism moves simultaneously with the working plate. The measuring jig of the present application can assist the two-dimensional measuring instrument to accurately measure the size of the electronic device.

Description

technical field [0001] The present application relates to the technical field of measuring fixtures, in particular to a measuring fixture. Background technique [0002] During the design, trial production and production process of electronic devices, it is necessary to accurately measure the structural dimensions of the electronic devices. The two-dimensional measuring instrument has the characteristics of accurate measurement and simple use, and has unique advantages in the measurement of tiny dimensions. However, due to the large magnification of the secondary element measuring instrument, the electronic device needs to be moved when the secondary element measuring instrument measures large-scale features. The reference standards of the electronic device are different before and after the movement, which reduces the measurement accuracy. Contents of the invention [0003] The application provides a measuring fixture, the measuring fixture includes a fixed plate, a worki...
