Product catalog summary
Pneumatic Clamping Fasteners Overview
This document outlines the specifications and guidelines for pneumatic clamping fasteners, including pin holding clamps, ball-locking clamps, and ID holding clamps, each tailored for specific applications with distinct features.
Specifications
  • Pneumatic Pin Holding Clamps (PPHC): Available in single (PPHC-S) and double-acting (PPHC-D) versions, these clamps operate at air pressures of 0.3 to 0.7 MPa and provide clamping forces between 30 to 40 N. They are made from stainless steel with nitrile rubber seals.
  • Clamping Pins (QCPC-M): Designed for use with PPHC clamps, these pins are made from SUS630 stainless steel and are precipitation hardened.
  • Pneumatic Ball-Locking Clamps (PBLC): Offered in spring clamping (PBLC1023S-SUS) and pneumatic clamping (PBLC1023A-SUS) types, these clamps operate at air pressures of 0.3 to 0.7 MPa with a clamping force of 50 N.
  • Pneumatic ID Holding Clamps (PIDHC): Suitable for diameters from φ16 to φ20, with a maximum clamping diameter of φ22, these clamps operate at air pressures of 0.3 to 0.7 MPa and have a holding force of 77 N.
Procedures and Recommendations
  • Use clean air by employing an air dryer and filter to remove moisture and debris, preventing malfunctions.
  • For precise locating, use locating pins and maintain a spacing tolerance of ±0.1 for repeated applications.
  • All clamps have a repeatability of ±0.2, ensuring consistent performance.
Performance and Application
  • Performance curves illustrate the relationship between air pressure and clamping/holding force, indicating optimal operating conditions.
  • Examples of applications include transferring between processes and securing robot hands on storage shelves.
Installation and Maintenance
  • Instructions for hole preparation and installation stress the importance of correct spacing and alignment.
  • Maintenance notes mention that color differences due to hardening treatment do not affect product function or quality.
