Precision-engineered recesses in starwheels or pocketed discs for accurate product positioning and transfer in automated assembly lines.

技术定义与适配语境
典型 星轮/口袋盘口袋/腔体 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A pocket or cavity is a precisely machined recess in a starwheel or pocketed disc component, designed to securely hold and transport individual items during automated manufacturing processes. These cavities maintain consistent product orientation and spacing as the disc rotates, enabling synchronized transfer between stations in packaging, assembly, or sorting systems. Critical dimensions include depth, diameter, and angular positioning relative to the disc's center.

定义
A pocket or cavity is a precisely machined recess in a starwheel or pocketed disc component, designed to securely hold and transport individual items during automated manufacturing processes. These cavities maintain consistent product orientation and spacing as the disc rotates, enabling synchronized transfer between stations in packaging, assembly, or sorting systems. Critical dimensions include depth, diameter, and angular positioning relative to the disc's center.
工作原理
The pocket/cavity operates on rotational indexing principles. As the starwheel or disc rotates, each cavity sequentially aligns with infeed and discharge points. Products are deposited into the cavity at the loading station, carried through the rotation arc, and released at the unloading station. The cavity's geometry ensures product stability during transport, while precise machining allows for high-speed operation with minimal vibration or misalignment.
材料
Typically manufactured from hardened tool steel (e.g.AISI D2H13)stainless steel (304 or 316)aluminum alloys (6061-T6)or engineering plastics (POMUHMW-PE) depending on application requirements. Surface treatments may include nitridingchrome platingor PTFE coatings to reduce friction and wear.

常见问题

What factors determine cavity material selection?

Material choice depends on product abrasiveness, required precision, operating speed, and sanitation needs. Steel offers durability for heavy items, aluminum reduces inertia for high-speed applications, and plastics prevent product damage for fragile items.

How are cavities maintained in production environments?

Regular inspection for wear, cleaning to prevent material buildup, and lubrication of bearing surfaces. Replacement is recommended when dimensional tolerances exceed ±0.1 mm or surface defects appear.
