Abstract

The utility model discloses a feeding cylinder sealing structure, which comprises a feeding cylinder body, a piston rod and a piston body, wherein the piston rod is horizontally arranged in the feeding cylinder body; a combined sealing ring is sleeved outside the piston body at a fixed end of the piston rod; and a sealing ring is sleeved in the middle of the piston rod. The utility model has the advantages that a circle of combined sealing ring is arranged outside the piston body, so that the overall sealing property of a piston mechanism is improved, and the flexibility of the piston rod is improved; and moreover, a sealing ring layer is arranged in the middle of the piston rod, so that the stability of a connecting component in the cylinder is improved, and the movable performance of the piston rod is improved.

Description

A kind of feeding cylinder sealing configuration
Technical field
The utility model relates to the improvement of oil hydraulic cylinder technology, relates in particular to a kind of feeding cylinder sealing configuration.
Background technique
Existing pusher is when pushing spindle; Because of its feeder structure assembly is tight inadequately, sealing is relatively poor on every side for internal piston; Thereby cause transmission efficiency on the low side always and can't guarantee its accuracy problems fully indirectly; Thereby influenced the working efficiency of integral device, in later maintenance, expended great amount of time and manpower.
The model utility content
To above defective, the purpose of the utility model provides a kind ofly to be had high tenacity sealing configuration, cylinder interior assembly and connects fastening, as to help enhancing productivity, being convenient to installation and maintenance feeding cylinder sealing configuration, to solve many deficiencies of existing technology.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of feeding cylinder sealing configuration comprises feeding cylinder body, piston rod, piston body, and said feeding cylinder interior is horizontally disposed with piston rod, and the piston body outside at said piston rod fixed end position is with combined seal ring, and piston rod medium position place is with seal ring.
The beneficial effect of the described feeding cylinder of the utility model sealing configuration is: through in piston body outer installment one circle combined seal ring, improved the overall tightness of piston mechanism, the flexibility that has improved piston rod; Through one deck seal ring being set in piston rod medium position place, helped improving the steadiness of cylinder interior connection part, improved the activity performance of piston rod.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the said feeding cylinder of a utility model embodiment sealed structural representation.
Among the figure:
1, feeding cylinder body; 2, piston rod; 3, piston body; 4, combined seal ring; 5, lock washer; 6, nut; 7, cylinder body bonnet; 8, slide block; 9, seal ring.
Embodiment
As shown in Figure 1; The described feeding cylinder of the utility model sealing configuration; Comprise feeding cylinder body 1, piston rod 2, piston body 3, slide block 8; Feeding cylinder body 1 downside is installed slide block 8, and said feeding cylinder body 1 inner horizontal is provided with piston rod 2, and piston body 3 outsides at said piston rod 2 fixed end positions are with combined seal ring 4; Said piston body 3 ends are provided with a circle lock washer 5 and by nut 6 lockings, this feeding cylinder body 1 end is provided with cylinder body bonnet 7 and feeding cylinder body 1 is movably connected on the seal ring 9; Said piston rod 2 medium position places are with seal ring 9 to improve the steadiness of cylinder interior connection part.
