Swing clamp with planar rotation – 160 bar – Hydraulic sensing of clamped position PL21XH
Double-action - planar rotation - electrical position check
Force at 160 bar: 5 kN
This double-acting swing clamp includes a hydraulic position check system. The clamp includes a pressure limiter that closes from a preset position.
The system allows the workpiece position to be checked before the machining cycle starts.
This check is carried out with no additional circuit or electrical connection, thus reducing the costs of failure or fixture costs.
• clamping arm: see accessories section
• right or left planar rotation, 90° ±2°
• other rotation angles on request
• rod indexing X as an option (see below)
• maximum service pressure: 160 bar
Clamps are supplied with O-rings, lock nut and lock washer
(dimensions and tightening torque: see Lock washer for clamp type P11, P21 and Nut for clamp type P31 and P41)
O-rings: 5.28 x 1.78 90 NBR
Definition of forces depending on clamping arm: consult the guide
Important recommendations: consult the guide
Swing clamps with hydraulic sensing detect any incorrect positioning of workpieces in a fixture. Such detection requires no additional circuit.
Case 1: The workpiece is correctly positioned
• the clamp holds the workpiece in the required position
• the pressure limiter shuts
• the circuit then reaches the normal clamping pressure
• the pressure switch switches
• the machining cycle can start
Case 2: The workpiece is not correctly positioned
• the clamp does not hold the workpiece in the required position
• the pressure limiter remains open
• the circuit pressure remains low
• the pressure switch does not switch
• the machining cycle cannot start
