Latest Patents

One of Adachi's latest inventions is an automatic screw fastening machine. This machine transmits the rotating force of a motor to a driver bit through a differential planetary mechanism. This mechanism consists of an input disc, a plurality of planetary cones, a cam disc, and a variable-speed ring. The design includes a resilient supporting unit that restricts the variable-speed ring from shifting in the axial direction. Additionally, the machine features a torque detection unit that can detect the torque of the reaction force applied to the variable-speed ring due to the load on the driver bit. When the detect-signal value matches a specific value corresponding to the predetermined fastening torque, the power supply to the motor is discontinued. Consequently, the rotation of the driver bit is reduced to zero upon completing the screw fastening process. This design prevents the driver bit from being adversely affected by its own inertia, allowing it to stop simultaneously with the completion of the fastening process. The automatic screw fastening machine thus offers unparalleled capability in executing screw fastening processes by securely applying the desired fastening torque.
