Clamp cylinder, also called fingerscylinder, pneumatic fingers, etc., currently Its application is very wide, so what is the working principle of the gripper cylinder? What are the advantages of the gripper cylinder structure? Let me talk to my friends about this issue in detail below.
Working principle of gripper cylinder, structural advantages of gripper cylinder
The air pressure clamp has the advantages of "flat, thin and delicate, high-strength clip, multi-sided fixation, and built-in magnet".
The working principle of the clamping cylinder is to use a thin cylinder body, and process a positioning pin hole on the body to install the claw piece and the toggle rod. When the piston rod is pressed upward or When pushing downward, the claw piece or the toggle rod opens and closes through the toggle tip on the upper end of the piston rod.
Structural advantages:
1. The main body is flat, thin and compact, taking up less space, and reserves a variety of fixing methods for users to choose from.
2. There are two clamping methods. Users can choose either method according to their needs and install the clamping fixture.
Working principle of parallel gripper cylinder
The piston drives the moving body outside the cylinder to move synchronously through magnetic force. Its working principle: a set of high-strength magnetic rings are installed on the piston. The magnetic lines pass through the thin-walled cylinder and interact with another set of magnetic rings set outside. Since the two sets of magnetic rings have opposite magnetic properties, they have a strong suction. When the piston is pushed by air pressure in the cylinder, it drives the magnetic ring sleeve outside the cylinder to move together under the action of magnetic force. The thrust of the cylinder piston must match the suction force of the magnetic ring.
There is a groove in the axial direction of the cylinder tube, and the piston and Shangzhi move in the upper part of the groove. In order to prevent leakage and dustproof requirements, stainless steel sealing tapes and dustproof stainless steel tapes are used at the opening to be fixed on the cylinder heads at both ends. The piston frame passes through the groove to connect the piston and Shangzhi as a whole. The piston is connected to the Shangzhi and drives the actuator fixed on the Shangzhi to achieve reciprocating motion.
Working principle and usage of gripper cylinder
The working principle of the clamping cylinder: through the action of two pistons, each piston is connected to the Qigong fingers by a roller and a hyperbolic pedestal to form 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.
Methods and precautions for using the gripper cylinder (air claw)
1. When installing the air claw and accessories, the thread tightening torque should be within the allowable range. When installing the accessory on your fingers, do not allow 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.
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 range of small opening distance and large opening distance is 20mm-100mm. The opening distance of the air claw when the clamping jaw is released, such as moving a certain clamping distance during clamping, is subtracted from the two, and 1mm-3mm must be reserved.
When selecting the clamping jaw cylinder, different models have different clamping forces.
Through the above content, we have understood the working principle of the clamping cylinder. It can be seen that the structure of the clamping cylinder has many advantages. Everyone is using the clamping jaw< span style="color:#003399;">Cylinder, you also need to pay attention to the correct method of use.
