Abstract

The invention relates to a pneumatic cradle of ring spinning, pertaining to the spinning machine field. The pneumatic cradle comprises a lock-sheet combining member, an air-controlled position combining member, a handle combining member, a cradle-body handle combining member and auxiliary members, wherein the lock-sheet combining member is connected with a cradle body by a lock-sheet rotating pin which is fixed on the cradle. The air-controlled position combining member is connected with the cradle body by an air-controlled sheet rotating pin which is fixed on the cradle body, and can rotate around the air-controlled sheet rotating pin. The pneumatic cradle inherits that the cradle is lifted by raising a handle in operation practice, and realizes a direct pneumatic cradle lifting method which is hard to realize. Pressure relief is carried out by first releasing high-pressure gas in a gasbag, and consequently the release of pressure is also convenient. When pressurizing, the high-pressure gas does not enter the gasbag, only after the pressurizing is totally in place, the high-pressure gas is put through, consequently, the pressurizing is also convenient. The pneumatic cradle also solves a big problem that parts manufactured by a pushing handle method have poor processing technological performance, unreliable reposition, and large quantity of applying and releasing pressure.
