Pad Holder / Body for Vacuum Pad Assemblies

Product Specifications

Technical details and manufacturing context for Pad Holder / Body

Definition

The Pad Holder / Body is the main structural component of a vacuum pad assembly. It provides the mounting interface, houses the vacuum pad, and maintains seal integrity during operation. This component serves as the connection point between the vacuum system and the workpiece being handled. It creates a sealed chamber around the vacuum pad, allowing negative pressure (vacuum) to be applied through internal channels. This pressure differential enables the assembly to grip and manipulate objects securely. The holder is typically manufactured from aluminum, stainless steel, or engineering plastic, depending on application requirements. Key parameters include operating pressure (1.0–1.6 MPa), temperature range (-40 to 85 °C), vacuum port size (G1/8–G1/2 per ISO 228-1), pad diameter range (10–80 mm), material grade (e.g., 6061-T6 per ASTM B221), surface roughness (Ra 0.8–1.6 µm per ISO 1302), tolerance (±0.05 mm per ISO 2768-m), weight (0.05–0.5 kg), thread type (M5–M12 per ISO 965-1), maximum vacuum (-0.1 MPa), IP rating (IP54–IP65 per IEC 60529), and operating humidity (0–95% RH, non-condensing). These values are reference ranges and must be verified for the specific model and application. The holder's design affects holding force, sealing, wear, and dynamic response. Proper selection requires consideration of the vacuum pad size, mounting interface, and environmental conditions. Regular inspection for wear, corrosion, and seal integrity is recommended. Failure to maintain the holder can lead to loss of vacuum, reduced holding force, or system leakage. Always consult the manufacturer or supplier for model-specific specifications and compliance with relevant standards.

Working Principle

The Pad Holder / Body creates a sealed chamber around the vacuum pad. When negative pressure is applied through internal channels, the pressure differential between the ambient atmosphere and the chamber causes the pad to grip the workpiece. The holder maintains the seal integrity and provides a stable mounting interface, ensuring reliable operation.
