Abstract
The utility model discloses a kind of guiding rod structures for pilot unit, belong to the structure-design technique field of cylinder guidance bar, including symmetrically arranged guide rod and pedestal, the guide rod is movably arranged on pedestal, the pedestal both ends are respectively equipped in groove a and groove b, the groove a and groove b and are respectively equipped with copper sheathing a and copper sheathing b；One end of the groove a and one end of groove b are respectively fixedly connected with the retainer ring a and retainer ring b for preventing copper sheathing a and copper sheathing b from skidding off；The utility model wearability is good, increases the service life of pilot unit.
Description
Technical field
The utility model relates to the structure-design technique fields of cylinder guidance bar, more specifically to one kind for leading
To the guiding rod structure of unit.
Background technique
The pilot unit of cylinder can prevent the rotation of cylinder piston, and cylinder can be made to bear radial load, work indirectly
As principle be by guide rod on the pedestal of pilot unit, follow cylinder to move reciprocatingly, guide rod both ends have sealing ring
It is sealed.The material of existing guide rod sealing ring is rubber structure, and the work maximum temperature of General Purpose Rubber is 100 degrees Celsius,
Pilot unit follows cylinder to move back and forth, and rubber is easy to aging, and the sealing performance of the rubber after aging substantially reduces.
Utility model content
To solve defect existing in the prior art, the utility model provides a kind of guide rod knot for pilot unit
Structure, wearability is good, increases the service life of pilot unit.
The utility model is that technical solution used by solving its technical problem is: a kind of guide rod for pilot unit
Structure, including symmetrically arranged guide rod and pedestal, the guide rod are movably arranged on pedestal, the pedestal both ends point
Copper sheathing a and copper sheathing b She You not be respectively equipped in groove a and groove b, the groove a and groove b；One end of the groove a and recessed
One end of slot b is respectively fixedly connected with the retainer ring a and retainer ring b for preventing copper sheathing a and copper sheathing b from skidding off.
Further, the copper sheathing a and copper sheathing b equal length, groove a and groove b equal length, and copper sheathing a and copper sheathing b
The length for being shorter in length than groove a and groove b.
Further, the guide rod is equipped with oilhole.
Further, it is connected between the symmetrically arranged guide rod by guide plate.
Further, the guide rod slides in copper sheathing a and copper sheathing b.
Further, the symmetrically arranged guide rod respectively by one end be arranged threaded hole a and threaded hole b with lead
It is connected to plate.
Further, connector is fixed with by pressing plate on the guide plate.
The beneficial effects of the utility model are: the setting of pedestal both ends copper sheathing, realizes the guiding role to guide rod, it is fixed
Retainer ring on pedestal can prevent copper sheathing from skidding off with the movement of guide rod；The setting of copper sheathing and retainer ring replaces existing guiding
The rubber seal at bar both ends considerably increases the wearability of guiding rod structure, extends the service life of pilot unit；Lubrication
The setting of oilhole facilitates and supports maintenance to the profit of guide rod.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Appended drawing reference is as follows in figure: 1, guide rod, 2, retainer ring a, 3, copper sheathing a, 4, pedestal, 5, oilhole, 6, copper sheathing b,
7, retainer ring b, 8, groove a, 9, groove b, 10, guide plate, 11, connector, 12, threaded hole a, 13, threaded hole b, 14, pressing plate.
Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing and it is embodied
The utility model is described in detail in example.
Embodiment 1
A kind of guiding rod structure for pilot unit, including symmetrically arranged guide rod 1 and pedestal 4, the guide rod 1
It is movably arranged on pedestal 4,4 both ends of pedestal are respectively equipped with groove a8 and groove b9, the groove a8 and groove b9
Inside it is respectively equipped with copper sheathing a3 and copper sheathing b6；One end of the groove a8 and one end of groove b9, which have been respectively fixedly connected with, prevents copper sheathing
The retainer ring a2 and retainer ring b7 that a3 and copper sheathing b6 are skidded off.
The copper sheathing a3 and copper sheathing b6 equal length, groove a8 and groove b9 equal length, and copper sheathing a3 and copper sheathing b6
It is shorter in length than the length of groove a8 and groove b9.
The guide rod 1 is equipped with oilhole 5.
It is connected between the symmetrically arranged guide rod 1 by guide plate 10.
The guide rod slides in copper sheathing a and copper sheathing b.
The threaded hole a and threaded hole b that the symmetrically arranged guide rod is arranged by one end respectively are connect with guide plate.
Connector is fixed with by pressing plate on the guide plate.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is practical according to this in the technical scope that the utility model discloses
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
