Description
Technical field
The utility model relates to a kind of grinder pressure head structure.
Background technology
The pressure that grinder pressure head goes out cylinder body is directly connected to the machining accuracy of product, if insufficient pressure, then directly affects Product Precision.The cylinder body of existing grinder is prepared from primarily of aluminum alloy materials, due to piston rod frequent activities in cylinder body, easily causes cylinder body wall plucking and leaks gas, and then causing pressure head to go out the insufficient pressure of cylinder body, thus making product not reach the quality standard of regulation.
Utility model content
The utility model mainly solves the gas leakage of existing grinder cylinder body wall plucking and causes the technical problem of ram pressures deficiency.
For solving the problems of the technologies described above, the utility model embodiment discloses a kind of grinder pressure head structure, comprise the cylinder body of tool receiving space, steel bushing, piston head, piston rod and pressure head, described steel bushing to be contained in described cylinder body and to be close to its wall and arranges, described piston head is fixed on described piston rod upper end, the two is contained in described steel bushing, and described pressure head is located at described piston-rod lower end and part stretches out described steel bushing.
In a kind of preferred embodiment of the grinder pressure head structure provided at the utility model, described steel bushing comprises the first steel bushing and the second steel bushing, the internal diameter of described first steel bushing is greater than the internal diameter of described second steel bushing, and the two is connected and surrounds the cavity of described piston head and piston rod movement.
In a kind of preferred embodiment of the grinder pressure head structure provided at the utility model, described piston head is contained in described first steel bushing, and described piston rod is contained in described second steel bushing.In a kind of preferred embodiment of the grinder pressure head structure provided at the utility model, described piston head comprises the first noumenon stacked successively, sealing ring and the second body.
In a kind of preferred embodiment of the grinder pressure head structure provided at the utility model, between described piston rod and described pressure head, be also provided with sealing ring.
In a kind of preferred embodiment of the grinder pressure head structure provided at the utility model, described cylinder body is aluminum alloy material.
Compared to prior art, the grinder pressure head structure that the utility model provides is close at cylinder body wall and is provided with steel bushing, described piston head and piston rod are not directly contacted with described cylinder body wall, and directly contact with described steel bushing wall, cylinder body wall plucking can be avoided and leak gas, and the end of described piston head and piston rod is provided with sealing ring, the air-tightness of cylinder body can be strengthened further, thus ensure that pressure head goes out the pressure of cylinder body, and then ensure the machining accuracy of product, and substantially prolongs the service life of pressure head.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the grinder pressure head structure that the utility model provides.

Described steel bushing 2 is contained in described cylinder body 1, and is close to the setting of its wall.Described steel bushing 2 comprises the first steel bushing 21 and the second steel bushing 22.The internal diameter of described first steel bushing 21 is greater than the internal diameter of described second steel bushing 22, and the two arranges the cavity connecting and surround described piston head 3 and piston rod 4 and pump.
Described piston head 3 is fixed on described piston rod 4 upper end, and the two forms T-shaped structure.Described piston head 3 is contained in described first steel bushing 21, and closely cooperates with described first steel bushing 21 wall, and it comprises folded the first noumenon 31, sealing ring 32 and the second body 33 established successively.
Described piston rod 4 is contained in described second steel bushing 22, and closely cooperates with described second steel bushing 22 wall.
Described pressure head 5 is located at described piston rod 4 lower end, and part stretches out described second steel bushing 22.
Described sealing ring 6 is located between described piston rod 4 and described pressure head 5.
Compared to prior art, the grinder pressure head structure that the utility model provides is close at cylinder body wall and is provided with steel bushing, described piston head and piston rod are not directly contacted with described cylinder body wall, and directly contact with described steel bushing wall, cylinder body wall plucking can be avoided and leak gas, and the end of described piston head and piston rod is provided with sealing ring, the air-tightness of cylinder body can be strengthened further, thus ensure that pressure head goes out the pressure of cylinder body, and then ensure the machining accuracy of product, and substantially prolongs the service life of pressure head.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
