AirTAC cylinder (working principle)
Yadeke ordinary double-acting cylinder
1, 3-buffer plunger 2-piston 4-cylinder 5-guide sleeve 6-dust ring 7-front end cover 8-air port 9-sensor 10-piston rod
11-Wear-resistant ring 12-Sealing ring 13-Rear end cover 14-Buffer throttle valve
Taking the most commonly used single piston rod double-acting cylinder in pneumatic systems, it consists of cylinder barrel, piston, piston rod, It consists of front end cover, rear end cover and seals.
The interior of the double-acting cylinder is divided into two chambers by the piston. A cavity with a piston rod is called a rod cavity, and a cavity without a piston rod is called a rodless cavity.
When compressed air is input from the rodless chamber, the rod chamber is exhausted, and the pressure difference between the two chambers of the cylinder acts on the piston to overcome the resistance load and push the piston
Movement causes the piston rod to extend;when the rod cavity takes in air and the rodless cavity exhausts, the piston rod retracts. If there is a rod cavity and a rodless cavity, air intake and exhaust are alternately carried out.
The plug realizes reciprocating linear motion.
2. Classification of Airtac cylinders
There are many types of Airtac cylinders, which are generally classified according to the structural characteristics, functions, driving methods or installation methods of the cylinders. The classification methods are also different
. According to structural characteristics, cylinders are mainly divided into two types: piston cylinders and diaphragm cylinders. According to the form of motion, it is divided into two categories: linear motion cylinder and swing cylinder.
3. Installation form of Airtac cylinder
The installation form of Airtac cylinder can be divided into
1) Airtac fixed cylinder The cylinder is installed fixedly on the body, with foot type and Flange type.
2) Yade passenger pin cylinder. The cylinder body can swing at a certain angle around the fixed axis. There are U-shaped hook type and trunnion type.
3) YATACO rotary cylinder The cylinder is fixed on the machine tool spindle and can perform high-speed rotation with the machine tool spindle. This kind of cylinder is often used in machine tool pneumatics
Chuck to realize automatic loading of workpieces.
4) AirTAC embedded cylinder The cylinder barrel is directly made in the clamp body.
