The Air Shaft Adapter Can Turn A 3-inch Inflatable Shaft Into A 6-inch Air Expanded Shaft

3-inch to 6-inch inflatable sleeve clamp: divided into key inflatable sleeve clamp and plate inflatable sleeve clamp, used to cooperate with 3-inch inflatable shaft, 3-inch inflatable shaft sleeve clamp, can roll up raw materials with larger diameter of paper tube, can replace 6-inch inflatable shaft, can rewind and unwind larger diameter items.

The structure of the core adapter mainly includes: chuck body and air bag or rubber sleeve:
1) Chuck body: The inflatable chuck is generally composed of the chuck body, the inflatable shaft core and the sealing assembly. The chuck body is usually made of high-strength alloy steel or aluminum alloy material to ensure sufficient rigidity and stability to withstand large cutting or rotational forces, in some applications, the surface of the inflatable chuck may be specially treated or coated to enhance its performance, however, the specific information about the surface material of the inflatable chuck may vary depending on the manufacturer and model, so in the actual application it needs to be selected according to the specific needs. The inflatable shaft is a key component for the clamping function, and it has an internal airway that is connected to an external air source.
2) Airbag or rubber sleeve: The airbag or rubber sleeve is usually wrapped around the outside of the inflatable shaft core. These parts have good elasticity and wear resistance, and are able to expand evenly when inflated, holding the workpiece tightly. For example, the inflatable chuck used in some high-precision turning operations has an airbag made of a special rubber material that retains good elasticity and sealing properties during frequent inflation-deflation cycles.

The working principle of the inflatable sleeve clamp:
1) Clamping process: When the compressed air enters the space between the inflatable shaft core and the airbag (or rubber sleeve) through the airway, the airbag (or rubber sleeve) will expand outward evenly. Since the expansion is carried out evenly in the circumferential direction, a uniform radial clamping force can be generated on the workpiece placed in the chuck. This uniform clamping force ensures good concentricity and stability of the workpiece during machining. For example, when CNC lathes process slender shaft parts, the inflatable chuck can precisely control the air pressure so that the workpiece is clamped firmly and does not wobble during high-speed rotation.
2) Loosening process: When the workpiece needs to be replaced or the processing is completed, the compressed air in the chuck is discharged, and the air bag (or rubber sleeve) returns to its original state under the action of its own elasticity, so as to loosen the workpiece.

Main features of inflatable chuck:
Excellent material: The main body of the inflatable shaft is made of high-stress steel or aluminum alloy material, and the internal expansion body is composed of special synthetic rubber, which makes the fixture have excellent characteristics such as high strength, wear resistance and corrosion resistance.
Quick installation: When the internal air is released, the expansion extruded parts are retracted, and the inflatable axis is easily taken out, which is convenient for users to install and operate.
Safe and stable: When the fixture is working, the expansion part of the inflatable shaft can form a sealing environment that is closely combined with the coil, and the replaceable VT type reel bracket is used to ensure the safety and stability of the fixture.
Strong adaptability: The fixture structure is diverse, which can meet a variety of different working environments and requirements, such as center guide key type/plate type, surface rotation key bar type/plate type, independent adjustment slip type, etc.
Easy maintenance: The specifications and dimensions of the transmission part of the inflatable chuck can be designed and manufactured according to the customer's mechanical specifications and characteristics, and the overall structure has excellent rigidity, can withstand high torque, and is safe and free of loosening during rotation.

Application scenarios of inflatable sleeve clamps:
Inflatable chucks are widely used in various precision machining occasions, such as CNC machine tools, machining centers, automated production lines, etc., at the same time, in the coiling and unwinding equipment and assembly lines, such as papermaking machinery, plastic film making machinery, coating machines, laminating machines, rotary printing machines and other industries have also been more used.
Specific main areas:
1) Machinery manufacturing field:
The inflatable chuck has a wide range of applications in the field of machinery manufacturing, especially when it is necessary to clamp large or extra-long metal workpieces, such as aluminum alloy plates, bearings, special-shaped parts, etc., its high-precision and high-reliability clamping method ensures the stability and safety of the workpiece in the processing process.
2) Workshop processing:
In the process of workshop processing, pneumatic chucks (including inflatable chucks) are widely used in various machine tools, such as lathes, milling machines, etc., which can effectively clamp the parts on the machine tool and ensure the stability of the parts in the processing process, so as to improve the machining accuracy and efficiency.
3) Textile, printing and dyeing industry:
In the textile and printing and dyeing industry, the inflatable chuck is often used in the winding and unwinding equipment of the reel, and its characteristics of rapid connection save the time of manual operation of loading and unloading, and improve the efficiency of the whole operation.
4) Packaging and printing machinery:
In packaging and printing machinery, the inflatable chuck (especially the shaft seat type inflatable chuck) is widely used at both ends of the reel for receiving and discharging as a common connecting device, which can not only improve the operation efficiency, but also ensure the stability and quality of the printing or packaging process.
5) Other Industries:
In addition to the above-mentioned industries, the inflatable chuck is also used in steel machinery, wire and cable machinery, chemical machinery and other fields, and its unique clamping method and wide range of application make it an indispensable and important tool in modern manufacturing.

Problems to be aware of when using inflatable chucks:
1) Cleaning: Before using the inflatable chuck, you need to clean the surface of the chuck to ensure that there is no oil, iron filings and other impurities. These impurities may affect the clamping effect or even damage the inflatable chuck.
2) Control the air pressure: To control the air pressure of the inflatable chuck, too much or too little air pressure will affect the clamping effect. Too much air pressure can cause the airbag to burst, and too little air pressure may not be able to clamp the workpiece. Therefore, it is necessary to adjust the air pressure according to the actual situation and ensure that the air pressure is stable.
Choose the right airbag: Choose the right airbag according to the size of the workpiece to be clamped to ensure that the inflatable chuck can fully clamp the workpiece. Different sizes of workpieces need to choose different specifications of airbags, otherwise the clamping effect will be affected.
3) Proper installation: Before putting the workpiece into the inflatable chuck, you need to make sure that the surface of the workpiece is flat and free of burrs or impurities. At the same time, it is necessary to ensure that the inflatable chuck is installed correctly, and the components are firmly connected and will not be loose or fall off.
4) Moderate clamping: During the operation, the workpiece needs to be clamped moderately, not too tight or too loose. Too tight may cause damage to the inflatable chuck, and too loose will not guarantee the clamping effect. Therefore, it is necessary to adjust according to the actual situation to ensure that the clamping force is moderate.
5) Regular inspection and maintenance: The inflatable chuck needs to be inspected and maintained regularly, including checking the wear and tear of seals, airbags, splints and other components, and replacing damaged or worn parts in time. At the same time, the inflatable chuck needs to be lubricated and maintained to prolong its service life.
 

Choose the number of inflatable shaft adapters according to the length of the inflatable shaft:
If the inflatable shaft is relatively short below 500-600 mm, one shaft can be equipped with one, if the inflatable shaft reaches 1 meter or 2 meters, it is best to match two or three clamps on one shaft.
