Description
Technical field
The present invention relates to hydraulic cylinder technical field, specifically a kind of interior guiding anti-rotation hydraulic cylinder.
Background technique
In today of aluminium Industry Quick Development, large-scale aluminium manufacturer, hoistable platform on pig moulding machine is not allow in decline
Rotation, traditional scheme is that have four guide posts on four side of platform, and centre is a lifting cylinder, and hoistable platform exists when because of ingot casting
It is to be not allow for creeping phenomenon when landing down, this requires four guide posts and the corresponding pitch-row machining accuracy of hoistable platform are non-
Chang Gao, and cost is also relatively high.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of interior guiding anti-rotation liquid itself with anti-rotation, guide function
Cylinder pressure.
The invention is realized by the following technical scheme：Anti-rotation hydraulic cylinder, including cylinder body are oriented in a kind of；The cylinder base
It is fixed with pedestal, cylinder body top is fixed with end cap；Piston rod is installed in the cylinder body；The piston rod inner end is equipped with work
Plug, piston rod outer end slides through end cap；The piston rod inner end is provided with non-circular blind hole；The pedestal is provided with and piston rod
The opposite through-hole of blind hole；A guide rod is fixed in the base plate through holes；It is blind that guide rod inner end is slidably connected at piston rod
In hole, guide rod section is matched with piston rod blind hole section；The guide rod axle center is provided with through-hole, in the outer of guiding rod through-hole
End is equipped with air filtering plug.
It is further：Piston rod blind hole section is regular quadrangle；The piston rod section is regular quadrangle, piston
The stupefied rounded corner of bar.
The base plate through holes outer end is provided with deep gouge seam allowance, and the guide rod outer end is equipped with to be matched with pedestal deep gouge seam allowance
Shelves platform；It is bolted on the pedestal deep gouge seam allowance and the gland for being pressed on guide rod outer end is installed；In the gland
The heart is provided with through-hole.
Compared with prior art, the beneficial effects of the invention are as follows：The guiding of piston rod is completed by guide rod, moreover it is possible to anti-
The only rotation of piston rod, effectively prevents the lateral bending of the piston rod of hydraulic cylinder, at the same also reduce equipment manufacturing costs and
The maintenance cost in later period.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
In figure：1, cylinder body；2, pedestal；3, guide rod；4, end cap；5, piston rod；6, piston；7, air filtering plug；8, gland.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, being oriented to anti-rotation hydraulic cylinder, including cylinder body 1 in a kind of；1 bottom of cylinder body is fixed with pedestal 2, on cylinder body 1
Portion is fixed with end cap 4；Piston rod 5 is installed in cylinder body 1；5 inner end of piston rod is equipped with piston 6, and the sliding of 5 outer end of piston rod is worn
Cross end cap 4.
5 inner end of piston rod is provided with non-circular blind hole.Pedestal 2 is provided with the through-hole opposite with 5 blind hole of piston rod；In pedestal 2
A guide rod 3 is fixed in through-hole；3 inner end of guide rod is slidably connected in 5 blind hole of piston rod, 3 section of guide rod and piston
5 blind hole section of bar matches；3 axle center of guide rod is provided with through-hole, is equipped with air filtering plug 7 in the outer end of 3 through-hole of guide rod.
Preferably：5 blind hole section of piston rod is regular quadrangle；5 section of piston rod is regular quadrangle, the stupefied rounding of piston rod 5
Angle.
Preferably：2 through-hole outer end of pedestal is provided with deep gouge seam allowance, and 3 outer end of guide rod is equipped with and matches with 2 deep gouge seam allowance of pedestal
Shelves platform；It is bolted on 2 deep gouge seam allowance of pedestal and the gland 8 for being pressed on 3 outer end of guide rod is installed；8 center of gland
It is provided with through-hole.
Above-described embodiment can be seen that the guiding that this hydraulic cylinder completes piston rod by guide rod, moreover it is possible to prevent piston
The rotation of bar, effectively prevents the lateral bending of the piston rod of hydraulic cylinder, while also reducing equipment manufacturing costs and later period
Maintenance cost.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
