How the finger cylinder works:The working principle of the finger cylinder is through the action of two pistons. Each piston is connected to the Qigong fingers by a roller and a hyperbolic bed, forming a special drive unit. To achieve Qigong, the fingers always move axially and concentrically, and each finger cannot move independently. If the finger is moved in the opposite direction, the previously pressurized piston is in a vented state, while the other piston is pressurized.
1. Methods and precautions for selecting the size of the gripper cylinder (claw)
1. When installing the air claw and accessories, the thread tightening torque should be within the allowable range. When installing accessories on your fingers, do not put any resistance on your fingers
2. The clamping point distance L and the overhang H should be within the allowable range specified by the air gripper to prevent the fingers from bearing excessive torque and reducing the service life.
3. When the air claw clamps the workpiece, considering the size error of the workpiece and the presence of tape in the magnetic switch, the selected opening and closing stroke should have a certain capacity.
2. Parallel jaw cylinder clamping force characteristics:
The clamping jaws are in surface contact when clamped, and there is an opening distance when released. This opening distance varies according to different structural designs. It is generally in the range of 4mm-20mm, which is called The small opening distance and the large opening distance range are 20mm-100mm. The opening distance of the air claw when the clamping jaw is released. If the clamping distance is moved by a certain clamping distance during clamping, the two are subtracted and 1mm-3mm is reserved.
