Overview & Features
OSU/OSN (Oscillating Special Unit) is a device for automatic supply of work by using rotating roller gear cam, and up-down home cam and the model is used for high-speed and precise positioning.
OSU’s operating sequence is as follows. OSU descends and ascends 20~50mm to supply work, wheel 45°~ 180°, descend again to supply work, and ascend to return to its original position.
OSN’s operating sequence is as follows. OSN descends and ascends 20~80mm to supply work, wheel 30°~ 90°, descend again to supply work, and ascend to return to its original position.
Also, the model allows broad degree of freedom for timing chart and allows extensive response to a big turn angle.
Basic Structure
A complex device composed of 3 elements including two cams (roller gear cam & home cam) and cam follower.
High Speed
Refined cam curve, precisely processed cam, cam follower, and completely removed backlash allows high-speed operation.
High Productivity and Fixing
Quick setting time and precise positioning.
Less velocity fluctuation during operation and response to precise synchronization.
Economic Feasibility
No need for frequent maintenance and has excellent productivity for reducing the life cycle expense in automated system.
