When Loading the Pallet

When loading the pallet,
・ The pallet is set on the raised piston rod cap.
At this time, the lift-up function makes an adequate gap between the taper
reference surface and the seating surface. This allows to remove cutting chips
and ﬂuid eﬀectively, and prevent damage on the clamp during pallet loading.
When unloading the pallet,

The Benefits of Movable Taper Sleeve
With marginal error absorbed by the moveable taper sleeve, the clearance between
the clamp unit, taper sleeve and block is eliminated enabling the repetitive location
accuracy and stabilized clamping force.

① Absorbs tolerance variations in each location clamp and block .
② Absorbs wear of locating part due to long time use.
③ Absorbs space variations of mounting holes.
④ Absorbs space variations due to temperature change.

Notes :
※ 7. The specification indicates the value of one device.
※ 8. It indicates the weight of pallet in horizontal position (placed flat) that WVS can locate regardless of number of clamps.
Release air pressure is determined with the loading weight (fixture).
(Loading weight should be less than 80% of the lift-up force (Number of Clamps×Lift-Up Force)).
When using pallet in vertical direction, please contact us.
※ 9. It indicates holding force when air pressure is at 0MPa and may not satisfy the specifications.

※ 7. The dimensions in ( ) show those of VSB-F.
※ 8. The spring pin is included in VSB-C only.
※ 9. The guide block (VSB-G) is used only for guide clamp (WVS□-MG) and the free block (VSB-F) can be used for both datum clamp (WVS□-MD)
and guide clamp (WVS□-MG).
※10. Pallet with low rigidity (thin pallet or pallet made of aluminum etc.) may be deformed when mounting VSB block.
In this case, tolerance of mounting hole machining dimension AA±0.010 should be close to ＋0.010 (the upper limit of the tolerance).

※ 8. Pallet with low rigidity (thin pallet or pallet made of aluminum etc.) may be deformed when mounting VSB block.
In this case, tolerance of mounting hole machining dimension AA±0.010 should be close to ＋0.010 (the upper limit of the tolerance).

Cautions● Notes for Design
1) Check Speciﬁcations4) Seat Setting● Please use each product according to the speciﬁcations.

● In case the clamp/block conﬁguration is linear, it is recommended
to provide additional supports for stability.

2) Notes for Circuit Design● Ensure there is no possibility of supplying air pressure to the lock port
and the release port simultaneously. Improper circuit design may lead

● Air blow passage should be φ6 or more for an eﬀective air blow.

to use rough guides to load the pallet within the allowable oﬀset.

● As the workpiece ﬁxture plate may fall down when releasing, it isrecommended to set up the latching mechanism to prevent a fall.
● When the pallet is used in vertical position (hanging on the wall),the internal moving parts tend to wear out. Please Check the locating
accuracy on a regular basis, and replace the product in case the locating
accuracy exceeds the allowable range.
Example of Latching Mechanism

Rough Guides(Two)● The pallet must be level with the base plate during loading andunloading, otherwise the clamps and blocks will be damaged.
Provide guide pins to keep the pallet level during loading and unloading.

● When the pallet is in horizontal position, make sure the weightof the workpiece ﬁxture is less than the lifting force of the clamps
and maximum load of the machine.
● When the pallet is in vertical position, make sure the weight of theworkpiece ﬁxture pallet is 10% of the clamping force.
● Please contact us in case the pallet is in other position.

● Continuous use with contaminant on components will lead tolocating accuracy failure, malfunction and ﬂuid leakage.

4) If disconnecting by couplers, air bleeding should be carried out
on a regular basis to avoid air mixed in the circuit.
5) Regularly tighten nut, bolt, pin, cylinder, pipe line and others toensure proper use.
6) Make sure the hydraulic ﬂuid has not deteriorated.
7) Make sure there is a smooth action without an irregular noise.
● Especially when it is restarted after left unused for a long period,
make sure it can be operated correctly.
