It needs to be replaced after damage, maintenance cost is high；2. the both ends of piston do not have protrusion, the sense close to switch at cylinder cavity both ends
It answers sensitivity poor, thereby reduces control precision.
Utility model content
The purpose of the utility model is to provide a kind of oil cylinder piston of pressurized generator, the maintenance costs of the oil cylinder piston
It is low, and the induction sensitivity close to switch can be improved, to mention high control precision.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of oil cylinder of pressurized generator
Piston, the middle part of the oil cylinder piston are equipped with the seal groove for installing sealing ring, and the both ends of the oil cylinder piston are respectively equipped with
Shape protrusion cylindrical, one end of the protrusion are equipped with the first mounting groove of circular in cross-section, first peace
The bottom of tankage is equipped with the second mounting groove of circular in cross-section, and the internal diameter of second mounting groove is less than first mounting groove
Internal diameter, the inner headed face of second mounting groove is equipped with groove, and the groove extends along the circumferencial direction of second mounting groove,
The inner headed face of first mounting groove is equipped with card slot, and the card slot extends along the circumferencial direction of first mounting groove.
Further, the height of the protrusion is 30mm.
Further, the width of the card slot is less than the width of the groove.
Further, the cross section of the seal groove is in " Kan " shape.
The utility model the utility model has the advantages that the utility model oil cylinder piston, both ends be equipped with protrusion, one end of piston rod
It is connected to protrusion, therefore is not required to be equipped with built-in static sealing ring, reduces vulnerable part, reduces maintenance cost；Due to oil cylinder
The both ends of piston are equipped with protrusion, facilitate access to the induction of switch, improve the induction sensitivity close to switch, and then improve
Control precision.

Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As shown in Figs 1-4, the oil cylinder piston 1 of the pressurized generator of the present embodiment.The middle part processing of the oil cylinder piston 1 is useful
In the seal groove 12 that the cross section of installation sealing ring is in " Kan " shape.It is cylindrical that the both ends of oil cylinder piston 1 are machined with shape respectively
Protrusion 11, the height of protrusion 11 is 30mm, and one end of protrusion 11 is machined with the first mounting groove of circular in cross-section
13, the bottom of the first mounting groove 13 is machined with the second mounting groove 15 of circular in cross-section, and the internal diameter of the second mounting groove 15 is less than
The internal diameter of first mounting groove 13, the inner headed face processing fluted 16 of the second mounting groove 15, circle of the groove 16 along the second mounting groove 15
Circumferential direction extends, and the inner headed face of the first mounting groove 13 is machined with card slot 14, and card slot 14 prolongs along the circumferencial direction of the first mounting groove 13
It stretches, the width of card slot 14 is less than the width of groove 16.
Oil cylinder piston 1 is installed on the structure in oil cylinder 3 as shown in figure 5, oil cylinder piston 1 is loaded on the inner cavity of oil cylinder 3, piston rod
