“Impact Actuator” is an electric hammer that applies a striking force to the work (object) to move it by using the inertia force of rapid expansion and contraction of the piezo-electric actuator.
The actuator can be used for fine position adjustment of components during assembly and rotation centering, etc.
| Actuator Mechanism, Actuator location |
Mechanism
The top end of the actuator is abruptly elongated in sub-milliseconds to impact an object and then quickly returns to its original position.
Actuator location
2-way adjustment
As 1 actuator works in 1 direction, locate 2 opposed actuators for traveling in both direction.
1-way adjustment
For applications such as centering adjustment while rotation, etc., use 1 actuator for adjustment.
Applications
• Positioning of temporarily tightened parts
• Centering of discs and rotary parts
• Optical axis adjustment for laser optics
• Precision press-in
• Lens centering
• Oscillation source
