AI Technical Summary
The existing measuring machine platform lacks a positioning device, resulting in inaccurate part clamping, complicated operation, inability to effectively utilize automation functions, impacting inspection efficiency and increasing additional tooling costs.
Design a positioning device based on a measuring machine platform, consisting of a base plate and a tray. The base plate is used to change the direction of the coordinate axes, and the customized limit blocks on the tray are used to achieve precise positioning and quick part change of the parts. The device includes a support block, a customized limit block and a locking plate to ensure that the parts are aligned with the coordinate axes of the measuring machine platform.
It enables rapid and accurate positioning of parts, reduces alignment time, lowers tooling costs, improves inspection efficiency, supports integrated clamping in both directions, and is suitable for widespread application.
