Product catalog summary
Overview: This document provides comprehensive details on the Series CKQ U/CLKQ UG Pin Clamp Cylinder, including specifications, component descriptions, and assembly instructions for various configurations.
Material Specifications: The cylinder components are made from materials such as stainless steel, aluminum alloy, tool steel, and structural steel, each associated with specific parts like shims, cylinder tubes, lock bodies, and seals.
Component Descriptions: Key components include the body, guide pin, clamp arm, piston, seals, and various bolts and pins, each with specific materials and dimensions.
Construction and Dimensions: Detailed diagrams and dimensions are provided for different clamping heights (HIGH and LOW) with and without shims, specifying guide pin diameter and applicable hole diameter of the workpiece.
Specifications: Basic specifications include proof pressure, maximum operating pressure, action type, bore size, fluid type, and operating temperature range. Locking specifications cover locking action, unlocking pressure, and holding force.
Clamping and Maintenance: Clamping specifications detail stroke length, clamp arm details, and guide pin shapes. Maintenance parts and replacement kits include piston seals, rod seals, and grease packs.
Ordering Information: Guidance is provided on ordering cylinders, specifying options for body shape, port thread type, guide pin shape, auto switch type, and clamping height, with tables for applicable auto switches.
Specifications and Design Considerations: The lock holding force is 982 N, and circuit design must account for this force, especially when operating pressure exceeds 0.75 MPa. The cylinder takes approximately 0.3 seconds to generate clamping force from an unclamped state.
Component Materials: Components are made from materials like aluminum alloy, stainless steel, structural steel, and others, with specific parts including the body, guide pin, clamp arm, and seals.
Model Variations: Models include CKQGK50-RLS, CKQGK50-RHS, and CKQGK50-RH, with variations in clamping height and shim presence.
Dimensions and Mounting: Dimensions are provided for components, including guide pin diameters and applicable hole diameters for workpieces, with mounting specifications for different model types.
Additional Notes: Maintenance services should be consulted with SMC, as seal kits for the CLKQ series with lock are not available. Auto switch options are detailed.
Auto Switch Mounting Procedures: Instructions for mounting auto switches include using specific brackets and screws, emphasizing securing the auto switch to prevent movement.
Safety and Precautions: Safety precautions include risks of sudden cylinder action, the need for protective covers, and securely tightening all parts. Equipment should be designed to prevent maximum theoretical force application to the cylinder.
Operating and Selection Guidelines: Guidelines are provided for adjusting cylinder speed and selecting the appropriate guide pin diameter, with a table showing maximum workpiece thickness.
Warnings and Cautions: Warnings include not using the cylinder for intermediate stops and selecting the correct locking position. Cautions cover adjusting cylinder speed and protecting the auto switch.
Clamping Force and Operating Pressure: Tables detail clamping force at various operating pressures for different guide pin diameters, emphasizing designing circuits below maximum theoretical holding force.
Specifications and Precautions: Operation timing, durability considerations, guide pin and cylinder handling, foreign material prevention, and spatter direction are outlined.
Recommended Pneumatic Circuits: Recommendations include drop prevention and emergency stop circuits.
Mounting and Piping: Mounting torque and piping length specifications are provided.
Maintenance and Lubrication: CKQG/P cylinders are pre-lubricated, and additional lubrication should be avoided for CLKQG/P cylinders.
Magnetic Field Resistant Auto Switches: Precautions include ensuring no magnetic field during piston movement and maintaining safety distances from welding currents.
Manual Unlocking: Safety precautions and procedures for manual unlocking are provided.
