Description
B 1.891 Swing Clamps with Overload Protection Device
These hydraulic swing clamps are used when it is required to keep the fixture workpieces area free of straps and clamping components for unrestricted workpiece loading and unloading.
This design allows the use of swing clamps even in restricted places. The threaded-body swing clamp can be sunk directly into the fixture up to the hexagon.
Oil feed through two holes, allowing for 3 fitting and hose connections:
1. Individual connection
With only one swing clamp being used, both connections can be tapped directly.
2. Series connection
If several swing clamps arranged in a row, the arrangement and size of the hole must be in accordance with catalog sheet B1.891. Instead of the expander stopper also, of course, an G1/4 plug (Part no. 3610 006) may be used.
3. Connecting housing
By means of the connecting housing available as an accessory, the swing clamps can be individually fixed with screws and piped.
Standard swing angles are 45°, 60°, and 90° ±2°.
Mounting of the clamping arms can be made in any angular position
All units are equipped with piston rod wipers and with an overload protection device which catches at every 180° angle.
This is the initial position for the swing motion.
