T/WLJC 13-2018 Arc cam technology requirements

Scope

Scope: This standard specifies the technical requirements, inspection methods, inspection rules, marking, packaging, transportation, and storage of arc cams. This standard applies to arc cams used in high-speed non-gap transmission devices; Main technical content: The arc cam mechanism refers to the base body of the active cam being an arc rotating body, and the cam profile is made into a convex ridge. The intermittent motion and positioning of the indexing plate are achieved by changing the spiral ramp angle of the working surface. Rollers evenly distributed along the circumference of the indexing plate are installed on the driven turntable. During the formulation of this standard, the experience of the national major science and technology project "Disk-type Tool Library with Automatic Tool Changing Device" was summarized. The key issues such as the selection of key parameters of the arc cam's shape and position tolerance, the determination of limit tolerances, and the detection methods were mainly addressed. It has been used in the products of the national major science and technology project "Disk-type Tool Library with Automatic Tool Changing Device", and its technical maturity has been verified through practical application.
