Cautions

Notes for Design

1Check Specifications

Please use each product according to the specifications.

VWH locates and releases with air pressure.

VFH locates and releases with hydraulic pressure.

2) Notes for Circuit Design

Please read Circuit Reference to assist with proper hydraulic/

pneumatic circuit design.

Carry out sufficient advance review as the wrong circuit design

may lead to product malfunctioning and damage.

3Air Supply

Continuously supply air pressure to the air blow port.

If air supply is shut off during operation, contaminants

enter into the cylinder leading to malfunctions.

4Setting Up the Clamps

The expansion locating pin is a positioning cylinder and has

no clamping mechanism. A clamp must be provided separately.

5Mounting Direction (Phase)

CCut (VH-C) locates a workpiece in the direction of rotation,

based on DDatum (VH-D). Therefore, it is required to determine

the phase of CCut when mounting.

When mounting the product, make sure that expanding direction

of C (Cut) is perpendicular to D (Datum).

6Reference Surface towards Z-axis

This product has no seating. Please prepare a seat separately.

7 Adjusting Height of Expansion Locating Pin

Seating height can be selected from 15mm / 20mm / 25mm.

For slight adjustment of seating height and expanding part height,

install a spacer (3mm or less) under the flange.

Install a spacer block under the flange if the height of expansion

locating pin is not enough.

8When the workpiece is in vertical position.

When setting a workpiece, make sure it is in proper proximity and

square to the expansion locating pins.

If it is locked out of position, the products may be damaged.

As the workpiece may fall down during releasing, it is recommended

to set up the latching mechanism to prevent it from falling down.

When the workpiece is used in vertical position (hanging on the wall),

the internal moving parts tend to wear out. Check the locating accuracy

regularly, and if exceeding the allowable range, replace the product.

9Inclination in the Z-axis direction.

If a workpiece is tilted when loading/unloading, expanded part

of expansion locating pin and workpiece hole will get stuck and

the cylinder and workpiece will be damaged. Workpiece should be

loaded and unloaded with less than 4/100 ~ 5/100 (approx. 2 ~ 3)

of tilt between workpiece and expansion locating pin plane.

The product will be damaged when a workpiece is tilted during

loading/unloading (especially when unloaded). Prepare guide pins

(rough guides) to keep the workpiece level during loading/unloading.

10) Thickness around the Workpiece Hole

Thin wall around the workpiece hole could be deformed by

expanding force, and locating accuracy would not fill the

specification. Please conduct trial testing before use.

11) Distance Accuracy of VWH / VFH

Distance accuracy between VWH / VFH mounting holes and

between workpiece holes has to be machined corresponding

with the allowable offset (VWH/VFH-C : Cut).

12) Depth of Mounting Hole

When the depth of mounting hole is not properly machined,

it may lead to insufficient expansion or damages on the product.

Expanding Direction

Expanding direction of standard model is the same as the direction of mounting bolt. Please contact us if needing to change the expanding direction of CCut.

If the equipment is taken apart or modified, the warranty will be

voided even within the warranty period.

1Removal of the Product and Shut-off of Pressure Source

Before the product is removed, make sure that safety measures

and preventive devices are in place. Shut off the pressure and

power source, and make sure no pressure exists in the air and

hydraulic circuits.

Make sure there is no abnormality in the bolts and respective

parts before restarting.

2Please clean the locating product regularly.

Locating products (VWH/VFH) can remove contaminants with

cleaning functions (air blow function). However, hardened cutting

chips, adhesive coolant, etc. may not be removed. Make sure there

is no contaminant before installing a workpiece/pallet.

Continuous use with contaminant on components will lead to

locating accuracy failure, malfunction and fluid leakage.

3If disconnecting by couplers, air bleeding should be carried out

on a regular basis to avoid air mixed in the circuit.

4Regularly tighten piping, mounting bolts, nuts, snap rings and

cylinders, etc. to ensure proper use.

5Make sure the hydraulic fluid has not deteriorated.

6Make sure there is smooth action and no abnormal noise.

Especially when it is restarted after left unused for a long period,

make sure it can be operated properly.

7The products should be stored in the cool and dark place without

direct sunshine or moisture.

8Please contact us for overhaul and repair.
