The invention provides an oval air cylinder. The oval air cylinder comprises a cylinder body, a sealing ring, a piston, an oval piston rod, an oval cylinder port flange and an oval cylinder port flange adjusting sleeve. A round hole is formed in the cylinder body, the piston is arranged at the edge of the bottom of the round hole of the cylinder body, the sealing ring is arranged on the outer wall of the piston, the output end of the piston is connected with the oval piston rod, the cross section of the oval piston rod is oval, the oval cylinder port flange is provided with a through hole matched with the oval piston rod, the oval cylinder port flange adjusting sleeve is provided with a through matched with the oval piston rod, and the oval piston rod penetrates out of the through hole of the oval cylinder port flange and then penetrates out of the through hole of the oval cylinder port flange adjusting sleeve. According to the oval air cylinder, a pneumatic press can work in various environments, and operation becomes more convenient due to component simplification; because the piston rod of the oval air cylinder can not rotate by itself, high guiding performance is achieved; the rotation angle precision of the piston rod can be adjusted so as to guarantee the matching precision of dies.
Description
technical field [0001] The invention belongs to the field of petroleum equipment, in particular to an elliptical cylinder. Background technique [0002] In traditional pneumatic presses, the components of the cylinder usually adopt a circular structure. This design makes it necessary to set a guide device outside the cylinder to prevent the cylinder piston rod from rotating when it is in use. This guide device is commonly known as a slider. Or moving beams. And this kind of structure will become very inconvenient when running into special occasions, such as when there is no larger space to accommodate it. In addition, in the field of manipulators, there are many manipulators that cannot provide the space for the outer guide device to the cylinder, so the traditional method is that the cylinder in my pneumatic press cannot complete the task. Contents of the invention [0003] The problem to be solved by the present invention is to provide an elliptical cylinder, which is ...
