The Pneumatic gripper Pneumatic cylinder, also known as the finger Pneumatic cylinder, pneumatic finger, etc., is currently widely used. So, what is the working principle of the gripper Pneumatic cylinder? What are the structural advantages of the gripper Pneumatic cylinder? Now let's have a detailed discussion about this aspect for our friends.
The working principle of the gripper Pneumatic cylinder and its structural advantages
The pneumatic gripper has the advantages of being "flat, thin and delicate, with high-strength clamping plates, multi-faceted fixation and built-in magnets".
The working principle of the gripper Pneumatic cylinder is to use a thin Pneumatic cylinder body. Positioning pin holes are machined on the body to install the gripper plates and the sliding rod. When the piston rod is pushed up or down by compressed air, the gripper plates or the sliding rod perform opening, closing and opening actions through the sliding pin at the upper end of the piston rod.
Structural advantages
1. The main body is flat, thin, compact and takes up little space. It reserves multiple fixing methods for users to choose from when installing.
There are two clamping methods. Users can choose either form according to their needs and install the clamping fixture.
The working principle of parallel gripper Pneumatic cylinders
The piston drives the moving body outside the Pneumatic cylinder block to move synchronously through magnetic force. Its working principle: A set of high-strength magnetic *** magnetic rings is installed on the piston. The magnetic field lines pass through the thin-walled Pneumatic cylinder barrel and interact with another set of magnetic rings on the outside. Due to the opposite magnetic properties of the two sets of magnetic rings, they have a very strong suction force. When the piston is pushed by air pressure inside the Pneumatic cylinder barrel, under the action of magnetic force, it drives the magnetic ring sleeve outside the Pneumatic cylinder barrel to move together. The thrust of the Pneumatic cylinder piston must be adapted to the suction force of the magnetic ring.
A groove is opened in the axial direction of the Pneumatic cylinder tube, and the piston and Shangzhi move at the upper part of the groove. To prevent leakage and meet the requirements of dust prevention, stainless steel sealing bands and dust-proof stainless steel bands are used at the openings to fix the Pneumatic cylinder heads at both ends. The piston frame passes through the groove ground, connecting the piston and the Pneumatic cylinder head as one. The piston is connected to the Shangzhi, driving the actuator fixed on the Shangzhi to achieve reciprocating motion.
The working principle and usage method of the gripper Pneumatic cylinder
The working principle of the gripper Pneumatic cylinder: Through the action of two pistons, each piston is connected to a pneumatic finger by a roller and a hyperbolic disc, forming a special drive unit. To achieve Qigong, the fingers always move axially towards the center, and each finger cannot move independently. If the finger moves in the opposite direction, the previously compressed piston is in the exhaust state, while the other piston is under pressure.
The usage method and precautions of the gripper Pneumatic cylinder (air gripper)
When installing the air gripper and accessories, the torque of the threaded fastening should be within the allowable range. When installing accessories on your fingers, do not apply any resistance to your fingers.
2. The distance L of the clamping point and the extension H should be within the allowable range specified by the pneumatic gripper to prevent the fingers from bearing excessive torque and reducing their lifespan.
When the pneumatic gripper holds the workpiece, considering the dimensional error of the workpiece and the magnetic tape of the magnetic switch, the selected opening and closing stroke should have a certain capacity.
Characteristics of the clamping force of the parallel gripper Pneumatic cylinder
When the gripper is clamped, it is in surface contact. When it is released, there is an opening distance. This opening distance varies depending on the structural design and is generally within the range of 4mm to 20mm, which is called the small opening distance. The large opening distance range is 20mm to 100mm. For the opening distance when the pneumatic gripper is released, if it moves a certain clamping distance during clamping, the difference between the two must be reduced by 1mm to 3mm.
When selecting a gripper Pneumatic cylinder, different models have different clamping forces.
