Abstract
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
The invention belongs to oil equipment field, especially relate to a kind of oval cylinder.
Background technique
In traditional pneumatic press, each component of cylinder adopt round structure usually, such design makes cylinder when by use, need the rotation preventing cylinder piston rod at the outer installment guiding device of cylinder, this kind of guiding device is commonly called as slide block or dynamic beam.And this kind of structure is when running into more special occasion, when being held as there is no larger space, will become very inconvenient.Among the field of mechanism hand, have a lot of mechanism hand can not provide the space of outer guiding device to cylinder in addition, such Traditional Method is that cylinder in my pneumatic press just can not be finished the work task.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of oval cylinder, carries out work under being particluarly suitable for various production space, saves working space, can be applied on various pneumatic press and automatic line.
For solving the problems of the technologies described above, the technical solution used in the present invention is: provide a kind of oval cylinder, comprise cylinder body, seal ring, piston, oval piston bar, oval cylinder mouth flange and oval cylinder mouth flange adjusting sleeve, circular opening is provided with in cylinder body, the circular opening bottom margin place of cylinder body is provided with piston, and piston outer wall is provided with seal ring, piston is closely fixed by the sidewall of seal ring and cylinder body circular opening, the output terminal of piston is connected with an oval piston bar, the cross section of oval piston bar is oval, the free end of oval piston bar extends to outside cylinder body circular opening, and oval cylinder mouth flange is provided with the through hole matched with oval piston bar, oval cylinder mouth flange adjusting sleeve is provided with the through hole matched with oval piston bar, after oval piston bar passes from the through hole of oval cylinder mouth flange, pass in the through hole of oval cylinder mouth flange adjusting sleeve again.Seal ring is provided with between oval cylinder mouth flange and oval piston bar.Oval cylinder mouth flange adjusting sleeve is provided with precision adjustment hole
In use, because piston is closely connected with inboard wall of cylinder block by seal ring, make piston in the course of the work, can not deflect, therefore piston only give a kind of power being parallel to oval piston bar axis of oval piston bar, and oval piston bar due to its cross section be ellipse, it can not be rotated along axle, and the ellipse hole of oval cylinder mouth flange and oval cylinder mouth flange adjusting sleeve can limit the motion of oval piston bar, make it do axial promotion only, and rotation can not occur.Oval cylinder mouth flange adjusting sleeve then can adjust precision.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, make pneumatic press can carry out work under circumstances, because simplifying on parts makes operation become convenient; Because the piston cylinder of oval cylinder can not rotation, therefore possesses very strong guidance quality; And the corner accuracy of piston rod can be adjusted, ensure the identical precision of mould.And the present invention has structure simply, easy to maintenance, the advantages such as processing cost is low.

Embodiment
As Figure 1-3, the present invention is a kind of oval cylinder, comprise cylinder body 1, seal ring 2, piston 3, oval piston bar 4, oval cylinder mouth flange 5 and oval cylinder mouth flange adjusting sleeve 6, circular opening is provided with in cylinder body 1, the circular opening bottom margin place of cylinder body 1 is provided with piston 3, and piston 3 outer wall is provided with seal ring 2, piston 3 is closely fixed by the sidewall of seal ring 2 with cylinder body 1 circular opening, the output terminal of piston 3 is connected with an oval piston bar 4, the cross section of oval piston bar 4 is oval, the free end of oval piston bar 4 extends to outside cylinder body 1 circular opening, and oval cylinder mouth flange 5 is provided with the through hole matched with oval piston bar 4, oval cylinder mouth flange adjusting sleeve 6 is provided with the through hole matched with oval piston bar 4, after oval piston bar 4 passes from the through hole of oval cylinder mouth flange 5, pass in the through hole of oval cylinder mouth flange adjusting sleeve 6 again.Seal ring 2 is provided with between oval cylinder mouth flange 5 and oval piston bar 4.Oval cylinder mouth flange adjusting sleeve 6 is provided with precision adjustment hole
In use, because piston 3 is closely connected with cylinder body 1 inwall by seal ring 2, make piston in the course of the work, can not deflect, therefore 3, piston is parallel to the power of oval piston bar 4 axis to 4 one kinds, oval piston bar, and oval piston bar 4 due to its cross section be oval, it can not be rotated along axle, and oval cylinder mouth flange 5 and the ellipse hole of oval cylinder mouth flange adjusting sleeve 6 can limit the motion of oval piston bar 4, make it do axial promotion only, and rotation can not occur.Oval cylinder mouth flange adjusting sleeve 6 then can adjust precision.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
