Abstract
An elliptic pushing cylinder relates to a chemical fiber mechanical equipment technology, in particular to a pushing cylinder technology. The utility model includes a cylinder shell, a piston rod, a piston, a piston ring, and an obturating ring, wherein the piston rod is arranged with a front damper piston and a back damper piston, the inner cavity of the cylinder shell is of an ellipse, and the outer end is provided with a quadrate guideway. The outside diameter of the piston is of an ellipse, which is arranged at the middle of an elliptic piston and arranged with the piston ring, the two ends of the elliptic piston are arranged with the obturating ring, the elliptic piston is arranged between the front and the back damper pistons on the piston rod, and the back damper piston is fixed tightly on the piston rod by a nut. The elliptic pushing cylinder is simple in structure, and stable and reliable in working operation, the purpose that the piston is prevented from rotating in the course of to-and-fro movement is reached, and the volume of pushing cylinder is reduced over two thirds, thus not only saving the metal material, but also reducing the production cost and improving the quality.
Description
Technical field
Oval pushing cylinder cylinder relates to the chemical fibre equipment technology, relates in particular to pushing cylinder cylinder technology.
Background technology
In the existing machinery that is used for production of chemical fibre processing, its pushing cylinder cylinder bore generally all adopts cylindrical shape, and piston also is cylindrically to be complementary with it.In the cylinder both sides or a side be furnished with one or two guide posts, be used for preventing that piston rod piston when stretching out from producing rotation.The pushing cylinder cylinder of this structure, the volume of cylinder is very big, and diameter is Φ 50mm, complex manufacturing, cost height.Owing to increased by two guide posts in the cylinder both sides, pressure is big when starting, and produces the cylinder creeping phenomenon in work meeting in service, thereby influences the overall performance of cylinder.
Summary of the invention
The purpose of this utility model provides a kind of preventing and rotates the oval pushing cylinder cylinder of deviating from because of piston in the reciprocal running of piston.
This oval pushing cylinder cylinder comprises cylinder barrel, piston rod, piston, piston ring, sealing ring, damper piston and back damper piston before on piston rod, being provided with, and the cylinder barrel inner chamber is oval, the outer end has square rail; The external diameter ovalize of described piston is equipped with piston ring at oval piston middle part, at the oval piston two ends sealing ring is installed, and oval piston is arranged between the forward and backward damper piston on the piston rod, and back damper piston is fixed tightly on the piston rod by nut.
This oval pushing cylinder air cylinder structure is simple, and it is stable, reliable to work, and reaches the anti-rotation purpose of piston in the reciprocating motion process, and the volume that has dwindled the pushing cylinder cylinder again reaches more than 2/3, has both saved metal material, has reduced production cost again, has improved quality.

Fig. 2 is the A-A cut-away view of Fig. 1
Among the figure, the 1st, piston rod, the 2nd, protecgulum, the 3rd, bolt, the 4th, air inlet/outlet, the 5th, cylinder barrel, the 6th, preceding damper piston, the 7th, oval piston, the 8th, sealing ring, the 9th, piston ring, the 10th, sealing ring, the 11st, guide rail, the 12nd, back damper piston, the 13rd, nut, the 14th, bonnet.
Specific embodiment
In the outside of cylinder barrel 5 guide rail 11 is arranged, guide rail 11 and cylinder barrel 5 equal in length are provided with protecgulum 2 at an end of cylinder barrel 5, and tighten up connection by bolt 3, leave air inlet/outlet 4 between protecgulum 2 and cylinder barrel 5.Be provided with bonnet 14 in the rear end of cylinder barrel 5, all leave air inlet/outlet 4 between the two, and tighten up with cylinder barrel 5 by bolt 3 and to be connected.In use, piston rod 1 is connected with inner bolt hole in the chemical fiber machinery, and drive end bearing bracket 2 is connected with the ring flange of chemical fiber machinery, and tightens up cylinder barrel 5 simultaneously by bolt 3.When piston rod 1 drives oval piston 7 when reciprocating, piston 7 can not produce rotation and cause deviating from, thereby the work of assurance stable and reliable operation has improved product quality.
