Additional Information:

• Item Code: EH23340

Material:

Body:

• Tool steel, hardened, blackened

Clamping segments:

• Steel 1.4112, hardened and ground

Spring:

• Stainless steel

Note:

For clamping and centering of work pieces with internal bore. Exact self centering with a precision of ±0,025 mm. Due to the clamping segments being ground, work pieces with raw and/or machined surfaces can be frictionally connected, centered and held down at the seats. Large adjustment stroke and a low building height are a feature of the centering clamping element. Activate from either top or bottom.
Advice for activating from the top mounting: Take-off clamping plate and screw. Fasten body by means of threaded pin via WS₂.

Material:

Body:

• Case hardened steel, nitrided, manganese phosphate treated and ground

Clamping jaws:

• Case hardened steel, nitrided, manganese phosphate treated

Housing:

• Aluminium, red anodised

Clamping process:

 

•  Push the floating clamp downward.
•  Pivot the clamping jaws in as far as possible.
• The floating clamp contacts the bottom of the work piece with a low spring load.
•  Tighten the floating clamp with a hexagonal nut (WS 24) having a min. torque of 50 Nm and a maximum torque of 115 Nm. In the clamping process, the work piece is clamped and simultaneously supported.

•  Releasing is done in reverse order.

Assembly and Set-Up:

 

•  Mount the floating clamp (M 16 connection thread) onto the device with a wrench (WS 55).
•  Adjust the height limit stop and the rotating area with the red sleeve and clamp with a set screw (3 x WS 3). When setting the height limit, consider tolerance of workpiece.
• For custom clamping situation, the standard upper clamping jaw supplied can be replaced by the exchange clamping jaws (23320.0062 / .0064 / .0066).

 

Note:

The floating clamp is used to clamp and support additional clamping points on components.

The benefits of the floating clamp are:
• especially suitable for large work pieces,
• no distortion in the clamping of unstable components
• avoids vibration during the processing,
• clamps ribs, beads and shackles to reinforce clamped components,
• distortion-free clamping of raw parts.

Material:

• Steel, case-hardened, blackened, ground

Note:

For increasing the clamping height of down-thrust clamps EH 23310.

Material:

• Case-hardened steel, case-hardened, blackened and ground

Note:

The clamping height can be increased by using height adjusting cylinders EH 23310. and disks EH 1107. and EH 1108. from the Halder Modular Jig and Fixture System. It can be reduced by employing clamping inserts, e.g. EH 22730.

The down-thrust clamps provide the following advantages:
• rapid manual clamping, by means of clamping screw, adjustable clamping lever or double eccentric lever,
• easy and quick changing of the work piece by swinging the clamping head to the left or right; continuously variable setting by means of positioning ring 23310.0350,
• when using a positioning ring 23310.0350 a repeatable precise clamping is ensured; h₂ will then be increased by 7 mm (s minus 7 mm),
• reduced space requirements due to compact design,
• easy adaptation even to large clamping heights by means of height adjusting cylinders.

Down-thrust clamps can be secured in two different ways:

•  in a T-slot,
•  directly to the mounting plate, e.g. of a fixture, by means of a set screw.

The cylinder has to rest on the entire surface. Exceeding of the clamping height is inhibited by the height limitation.

Material:

Body:

• Case hardened steel, nitrided, manganese phosphate treated and ground

Clamping jaws:

• Case hardened steel, nitrided, manganese phosphate treated

Housing:

• Aluminium, red anodised

Clamping Process:

 

•  Push the floating clamp downwards.
•  Pivot the clamping jaws in as far as possible.
• The floating clamp contacts the bottom of the work piece with a slight spring load.
•  Tighten the floating clamp with a hexagonal nut (WS 18) having a min. torque of 15 Nm and a maximum torque of 30 Nm. In the clamping process, the workpiece is clamped and simultaneously supported.
•  Releasing is done in reverse order.

Assembly and Set-Up:

 

•  Mount the floating clamp (M 12 connection thread) onto the device with a wrench (WS 46).
•  Adjust the height limit stop and the rotating area with the red sleeve and clamp with a set screw
• (3 x WS 2.5). When setting the height limit, consider tolerance of workpiece.
• Additional flexible possibility of fitting with holder 23470.0250 - for safe functioning, the thread bore must always be closed, e.g. set screw M 12 x 10 - or holding plate for down-hold clamps 23210.0740.
• For specific clamping situations, the standard clamping jaws supplied can be exchanged or replaced (see catalogue diagram; screw ISO 4762-M8-12.9, M max. = 43 Nm).
• Clamping jaws with an increased clamping range, refer to 23320.0050-0058, are available.

Note:

The floating clamp is used to clamp and support additional clamping points on components.

The benefits of the floating clamp are:
• no distortion in the clamping of unstable components,
• avoids vibration during the processing,
• clamps ribs, beads and shackles to reinforce clamped components,
• distortion-free clamping of raw parts.

 

Material:

• Case hardened steel, nitrided, manganese phosphate treated

Note:

The clamping jaws can be used for floating clamps 23320.0012 and 23320.0014 to increase the clamping range.
When using custom-made jaws, it is important to insert the tightening screw (M 8-12.9, 43 Nm) 10 mm deep into the clamp housing on the upper clamping jaw and 9 mm deep into the clamp housing on the lower clamping jaw.

Material:

• Case hardened steel, nitrided, manganese phosphate treated

Note:

The clamping jaws can be used for the floating clamp 23320.0016 to increase or decrease the clamping range.

Material:

• Heat-treated steel, tempered, quality 10, phosphated

Material:

• Heat-treated steel, tempered, blackened

Material:

Body:

• Steel, blackened

Pull-rod:

• Special steel

Wearing parts:

• Heat-treated steel

Material:

• Steel, case-hardened, blackened, ground\

Note:

Used as clamps in conventional fixtures. A reamed hole is provided in the body of the fixture. The hole depth has to be adapted to the desired clamping height. To provide a counter force, a support can be placed against the rounded end of the clamp (radius 22). This support can be flat, half-rounded or V-shaped. Clamping is achieved by means of a DIN 933 hexagon screw.
