Abstract
A kind of interior guiding hydraulic cylinder, including cylinder body and piston rod are the utility model is related to, the inside of the piston rod is provided with the interior pilot hole with piston rod diameter parallel, is provided with interior guide rod in the interior pilot hole, interior guide rod one end is connected with cylinder body；Realized and be slidably matched by interior spigot surface between the interior pilot hole and interior guide rod, wherein one section of cross section profile of the interior spigot surface is non-circular profile.The interior guiding hydraulic cylinder of this programme is the crawling problemses for solving hoistable platform, while also reduces equipment manufacturing costs and the maintenance cost in later stage.
Description
Technical field
The utility model provides a kind of interior guiding hydraulic cylinder, belongs to technical field of hydraulic equipment.
Background technology
The hoistable platform on pig moulding machine, it is not allow when declining in today of aluminium Industry Quick Development, large-scale aluminium manufacturer
Rotation, traditional scheme is that have four guide pillars on the side of platform four, and centre is a hoist cylinder, and hoistable platform exists during because of ingot casting
Down land when be to be not allow for creeping phenomenon, this require four guide pillars and hoistable platform it is corresponding pitch-row machining accuracy it is non-
Chang Gao, and cost is also higher.
The content of the invention
To solve the above problems, the utility model provides a kind of interior guiding hydraulic cylinder, this interior guiding hydraulic cylinder can be with
Remove four guide pillars of platform periphery, be oriented to completely by hydraulic cylinder itself.Concrete scheme is：
A kind of interior guiding hydraulic cylinder, including cylinder body and piston rod, the inside of the piston rod is provided with puts down with piston rod axis
Capable interior pilot hole, the interior pilot hole is interior to be provided with interior guide rod, and interior guide rod one end is connected with cylinder body；The interior pilot hole with
Realized and be slidably matched by interior spigot surface between interior guide rod, wherein one section of cross section profile of the interior spigot surface is not rounded wheel
It is wide.
Further, the non-circular profile is polygonal profile.
Further, the polygonal profile is regular polygon profile.
Further, the side number of the regular polygon profile is 3~8.
Further, preceding guide ring and rear guide sleeve are provided with the interior pilot hole, preceding guide ring is fixed on interior guide rod
Front portion, rear guide sleeve is fixed on the rear portion of interior pilot hole.
Further, the non-circular profile section of the interior spigot surface is located on rear guide sleeve.
Further, the interior pilot hole is honing circular hole.
Beneficial point of the present utility model is：The interior guiding hydraulic cylinder of this programme is provided with what is cooperated in piston rod inner
Interior pilot hole and interior guide rod, because interior spigot surface is provided with non-circular profile section, so when piston rod acts, in interior spigot surface
Under guiding, piston rod can only do linear reciprocating motion, and can not rotate, and realize the hoistable platform being connected with piston rod
It can only move up and down, and can not rotate.And due to there was only a guiding, avoid four guide pillars it is asynchronous caused by
Hoistable platform is creeped.
The interior guiding hydraulic cylinder of this programme is to solve the crawling problemses of hoistable platform, at the same also reduce device fabrication into
Sheet and the maintenance cost in later stage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of interior guiding hydraulic cylinder as shown in Figure 1, including cylinder body 10 and piston rod 2, the inside of the piston rod 2 are provided with
With the interior pilot hole of the diameter parallel of piston rod 2, the interior pilot hole is interior to be provided with interior guide rod 5, interior one end of guide rod 5 and cylinder body 10
Connection；Realized and be slidably matched by interior spigot surface between the interior pilot hole and interior guide rod 5, wherein the one of the interior spigot surface
The cross section profile of section is non-circular profile.Preceding guide ring 3 and rear guide sleeve 6 are provided with the interior pilot hole, preceding guide ring 3 is fixed on
The front portion of interior guide rod 5, rear guide sleeve 6 are fixed on the rear portion of interior pilot hole 5.After the non-circular profile section of the interior spigot surface is located at
On guide sleeve 6.The interior pilot hole is honing circular hole.
In the present embodiment, interior guide rod 5 is using the six square steel of cold drawn forming, and guide ring 3 before six square steel front portion is fixed is leading
It is copper guide ring to ring 3, six square steel rear portion is fixed on the cylinder bottom 9 of cylinder base by adpting flange 8, and rear guide sleeve 6 is six
Square guide sleeve, overlength is formed between preceding guide ring 3 and rear guide sleeve 6 and is oriented to.Again by second between piston rod 2 and cylinder body 10
Guide ring 4 and combined guided 7 realizes that overlength is oriented to.
Linked together at the top of the interior guiding hydraulic cylinder of the present embodiment by terminal pad 1 and the hoistable platform of pig moulding machine, this
Sample is achieved that the hoistable platform of piston rod connection can only move up and down, and can not rotate.And due to there was only one
Be oriented to, avoid four guide pillars it is asynchronous caused by hoistable platform creep.
