Description

Technical Field

[0001] The invention relates to an automatic positioning tool system, and in particular to an automatic positioning tool switching device used for measuring and inspecting machined products. Background Art

[0002] Positioning tooling refers to a mechanical structure used to reliably position parts during the measurement process, ensuring the stability of the position of parts during the process. Positioning tooling is widely used in working conditions that require precision in product positioning, such as machining accuracy in the mechanical processing industry, assembly accuracy in the automatic assembly industry, and any working condition that requires position and cannot be positioned through non-physical identification, but requires position accuracy, requires positioning tooling to achieve structural positioning, thereby meeting the process requirements for stable position. The structure of the positioning tooling is limited by product technology, structural characteristics, production capacity control, batch consistency accuracy control and other conditions. It is necessary to customize the positioning tooling according to the product being measured, and design a positioning structure that meets specific parts or specific similar parts. It is a purely non-standard mechanical structure with specific features for customized special machines.
