Maker shares DIY ultrasonic-controlled pneumatic pressing device
1 reports · 1 sources
A maker named /u/Sea_Speaker8425 shared a DIY pneumatic precision pressing device on Reddit r/robotics, built entirely from off-the-shelf components. The device uses an ultrasonic sensor to detect the distance of the rod end (a black circular plate), and an Arduino controls the actuator to move to the target position. According to the author's explanation, it uses a 5/2 directional valve in a very unconventional way, pushing the rod by exhausting air from both sides of the cylinder; because the two ports at the ends of the cylinder (port A and B) have different effective areas, two pressure regulators are also used to balance the forces and keep the rod at the target position. The author says there is almost no information of this kind online.

- Homemade Pneumatic Precision Press: Actuator Positioning Controlled by Ultrasonic Sensor and Arduino
A maker built a pneumatic precision press from off-the-shelf parts. The device detects the distance to the rod end (a black circular plate) with an ultrasonic sensor, and an Arduino controls the actuator's movement toward the target position. The maker used a 5/2 directional valve in an unconventional way, exhausting air from both sides of the cylinder to drive the rod, and because the effective areas at the two cylinder ports (port A and B) differ, used two pressure regulators to balance the forces and hold the rod at the target position.
