1. Installation
Precautions
Caution:
- There is a mechanical difference of -0.25 to +0.25° at the clamping end. Adjust externally using a shim.
- Adjust the clamp end angle so the clamp arm contacts the workpiece at +3° or less. Contacting at more than +3° may damage the clamp cylinder.
- Use a speed controller. Set unclamping to clamping time to 1 second or more, and clamping to unclamping time to 1 second or more. Excessive kinetic energy can cause damage.
- The product can be mounted on the side or front. Install with the specified tightening torque and ensure proper engagement length.
- Screw tightening torque and engagement length:
Thread size Tightening torque [Nm] Min. engagement length [mm] M8x1.25 12.5~15 10 M10x1.5 24.5~29.4 11 - Positioning pin engagement length:
Positioning pin size Min. engagement length [mm] ∅8H7 9 ∅10H7 11 - When using a side guide, attach it so that lateral loads are not applied to the clamp arm.
- Angle tolerance of the arm during unclamping:
Bore size [mm] Arm angle [°] 15 30 45 60 75 90 105 120 135 50 0/-3 0/-4 0/-5 0/-5 0/-5 0/-5 0/-5 0/-6 0/-9 63 1/-3 0/-4 0/-5 0/-5 0/-5 0/-5 0/-5 0/-6 0/-9 - Do not disassemble the power clamp cylinder. It is a sealed structure. Disassembly, except for replacing parts, may cause performance deterioration.
- Proximity switch output: The switch output signal is output near the clamping and unclamping ends. The clamping side output does not indicate the status where the cylinder is locked by the toggle mechanism.
- Lubricating the toggle mechanism: The toggle mechanism is lubricated for life and requires no further lubrication.
Power clamp cylinder mounting and setup procedure
Example 1: When using clamping force only (equipped with a workpiece receptacle)
CKZ5N type / CKZ5T type:
Diagram Description: Shows the CKZ5N and CKZ5T type cylinders with components labeled: Cylinder, Clamp arm, Shim, Clamping port, Unclamping port, Arm side block, Workpiece receptacle side block.
Procedure:
- A) Set the workpiece: Place the workpiece, supply air to the clamping port (without the arm side block), and operate the clamp arm to its end.
- B) Install a block on the arm side: In state A, attach the workpiece and the arm side block. Adjust the shim so there is approximately 0 mm space. Theoretically, no clamping force is applied at this stage.
- C) Make block contact adjustments (arm side): To generate clamping force, insert an additional shim. The shim thickness depends on arm length and operating pressure (refer to pages 8-10). Note that graphs are guides, with about 10% tolerance in the cylinder body.
- D) Exhaust air: While in the clamped state, exhaust the air and confirm the clamp arm does not open.
Example 2: When using a hard stop (not equipped with a workpiece receptacle)
CKZ5N type / CKZ5T type:
Diagram Description: Shows the CKZ5N and CKZ5T type cylinders with components labeled: Cylinder, Clamp arm, Shim (shim1, shim2), Upper hard stop, Hard stop, Arm side block, Clamping port, Unclamping port, Distance to hard stop.
Procedure:
- A) Set the hard stop: Supply air to the clamping port without installing the upper hard stop, and operate the clamp arm to its end.
- B) Install the upper hard stop: In state A, attach the upper hard stop and adjust shim ① so there is approximately 0 mm space between the upper hard stop and the hard stop. Theoretically, no clamping force is applied to the hard stop.
- C) Make upper hard stop contact adjustments: To generate clamping force, insert an additional shim. The shim thickness depends on the distance to the hard stop and operating pressure (refer to pages 8-10). Consider the distance to the hard stop as the arm length. Note that graphs are guides, with about 10% tolerance in the cylinder body.
- D) Make block contact adjustments (arm side): In state C, adjust shim ② so the arm side block contacts the workpiece.
- E) Exhaust air: While in the clamped state, exhaust the air and confirm the clamp arm does not open.
Relation between shim thickness and clamping force
Note: Use figures as a guide; there is about 10% tolerance in the clamp cylinder body. Inserting a shim exceeding the peak clamping force position on the graph will prevent lock activation. Insert a shim of appropriate thickness. Arm length is the distance between the clamp arm shaft and the clamping position.
CKZ5N type / CKZ5T type:
Diagram Description: Illustrates the CKZ5N and CKZ5T types, showing the clamp arm, fulcrum, shim, clamping position, and arm length. For Bore size 50, graphs show Clamping force [N] vs. Shim thickness [mm] for Arm lengths of 100mm and 150mm, with curves for operating pressures 0.3MPa to 0.6MPa. For Bore size 63, similar graphs are provided for Arm lengths of 100mm, 150mm, 200mm, 250mm, and 300mm, with curves for operating pressures 0.3MPa to 0.6MPa.
