1Common precautions for each size

1) Use air filtered through a 5-µm-element filter.

2) Before piping is connected to the power clamp cylinder it should be thoroughly flushed with air.

3) Only use the clamp arm in our catalog. Do not weld an arm to the cylinder.

4) Always use a speed controller, and set it so that it takes at least

1 second from unclamped to clamped, and at least 1 second

from clamped to unclamped.

5) This product is designed to be used after being adjusted using a

shim. For this reason, it is set to between 0° to +0.5° at the

clamping end as shown in Fig. 1.

 Procedure

A) Place the workpiece, supply air at clamp side without installing clamping block, operate the clamp arm to the end of clamp.

B) Under the above conditions, adjust shim so that the space between the workpiece and the clamping block is about 0 mm.

Theoretically there is no clamping force for holding a workpiece under this condition.

C) In order to generate clamping force from the state described in step B, insert additional shim. The thickness of the shim differs

depending on the arm length and pressure, so please refer to the graph on front matter 3 as a guide. About 10% error may

occur due to the difference in tolerance of the clamp cylinder body.

Insert a shim with appropriate thickness.

∗Arm length “L” indicates the distance between the clamp arm shaft and the clamping position.

For distance “A” between knock positioning pinhole and clamp arm shaft, refer to the Table 1.

 Precaution

When using the side guide to the clamp arm to prevent lateral motion, make sure not to apply a lateral load or galling to the clamp

arm.

 Procedure

A) Supply air at clamp side without installation of upper hard stop, and operate the clamp arm to the end of clamp.

B) Under the above conditions, adjust shim qso that the space between the upper hard stop and the lower hard stop is about 0

mm. Theoretically there is no clamping force to the lower hard stop under this condition.

C) In order to generate clamping force from the state described in step B, insert additional shim. The thickness of the shim differs

depending on the arm length and pressure, so please refer to the graph on front matter 3 as a guide. About 10% error may occur

due to the difference in tolerance of the power clamp cylinder body.

D) Under the state described in step C, adjust shim wso there is contact between the clamping block and the workpiece.

Single-side-arm type (R/L)

Use within the allowable arm end load range according to the

distance “L” from the fulcrum to the mounting tool’s center

Two-side-arm type (D)

Consider the weight of allowable arm end load according to

the center position “G” of each arm end load (W1+ W2), the

distance “L” to the fulcrum and the arm opening angle “θ”.

Use within the allowable range of (W1+ W2), in this case.

9 types of arm opening angles (unclamping angles) 15°, 30°, 45°, 60°, 75°, 90°, 105°, 120° and 135° are available for each standard size.

 Arm opening angle change procedure

1) When changing the arm opening angle, be sure to operate the cylinder to the clamping end, and confirm that the air inside the

cylinder has been exhausted.

2) Loosen the switch cassette mounting screw, and remove the switch cassette.

3) Remove the hexagon socket head cap screw (part A), and change the position of the screw to the required angle position, and

tighten it to the tightening torque shown below.

4) Mount the switch cassette to the body, and tighten the switch cassette mounting bolt to the tightening torque shown below.

When mounting the clamping arm in a vertical clamping position, note that the maximum angle will change.

5) Remove the stopper bolt of the head cover, and mount a different stopper bolt for other angles using the tightening torque below.

When replacing the stopper bolt, fix the head cover securely. If the stopper bolt is replaced without fixing the head cover, the

head cover may be displaced, causing air leakage. (Confirm the direction of the angle display.)

For the applicable stopper bolt part numbers, refer to page 4 for CKZ3N, and page 15 for CKZ3T.
