Preliminary remarks:

1. This operating manual is created under considera-

tion of DIN EN ISO 1100-1, DIN EN ISO 1100-

and the corresponding respective norms.

. For different tool clamping, the necessary force

transfer or moments for the necessary clamping

force is to be determined according to the VDI

guideline 3106 (compare VDMA guideline 34181).

The authorised speeds may also need to be adapted

accordingly.

3. This operating manual applies to all nominal sizes of

the locking unit. Assembly drawings and parts lists

for the individual nominal sizes can be requested

separately from the company RÖHM.

1. Description

1.1 Configuration and functional features

The “SuperLock” locking unit is part of an automatic

HSK tool clamping system. It serves the purpose of

transferring traction to the HSK clamping set and the

subsequent self-locking detent and maintaining the

clamping force. The standard version of the locking unit

is provided with a draw bolt extension on which a clam-

ping and release unit transfers the clamping and release

forces or clamping and release strokes (illustration 1).

clamping set (1), locking unit (2), pull bolt extension (3), clamp and

release unit (4)

The „SuperLock“ locking unit consists of the collet,

draw bolt, clamping sleeve, draw bar and guide

sleeve (illustration ). It is delivered as a complete

module which is fully assembled. The inserted pull

bolt is removed for installation (compare installation

and assembly). The remaining parts of the SuperLock

module may not be independently dismantled and

assembled.

Illustration 2: configuration of the “SuperLock” locking unit

After assembly of the locking unit, the pressure head

of the HSK clamping set is screwed together with

the draw bar of the locking unit. The draw bolt of the

locking unit are connected with an original Röhm

draw bolt extension, or an operating rod designed

specifically for the customer, to the shaft end during

assembly of the system.

The draw bar of the locking unit generally has a cen-

tral, sealed through-hole for the internal supply of the

medium. The use of this drill hole is only possible for

size HSK25 with a fitted pressure head on the HSK25

clamping set. The clamping sets of the other HSK no-

minal sizes (HSK3-HSK15) have through-holes for

the supply of the medium and can be combined with

the “SuperLock” locking unit without any additional

measures.

In the release position (illustration 3), the draw bolt is

driven up to the draw bar and the pressure head is in

the ejection position for releasing the HSK tool.

The clamping position (illustration 4) is achieved by

applying force to the draw bolts (draw bolt extension)

whereby the self-locking effect exists between the

male taper of the draw bolt and the female taper of

the collet. After reaching the clamping position, a

force application element (e.g. hydraulic piston) brings

the clamping and release unit back to a neutral positi-

on in which the draw bolt extension can freely rotate.

The clamping and release unit is to be designed so

that the stipulated clamping strokes and clamping

forces can be achieved. Particular attention is to be

paid to the possible clamping stroke range caused by

the tolerance of the HSK tools (also refer to assembly/

dismantling).
