Description
Technical field
The utility model relates to grinding machine technical field, especially, relates to a kind of grinding machine hydraulic system.
Background technology
The structural representation of existing grinding machine hydraulic system as shown in Figure 1, it comprises lathe bed 11, workbench 12, oil cylinder 13, piston head 14 and piston rod 15, the two ends of described piston head 14 are all connected with piston rod 15, namely passing in and out oil cylinder 13 is two rods, and described piston rod 15 is provided with O RunddichtringO with the junction of described oil cylinder 13.Frequent owing to working, usually cause the junction leakage of oil of piston rod 15 and described oil cylinder 13, leak, cause oil cylinder fluid to scrap thus, the guide rail on workbench also easy-to-rust damages, and makes lathe lose precision, causes product rejection.
Utility model content
The utility model mainly solves the leakage of oil of existing grinding machine hydraulic system oil cylinder, steel guide rail easy-to-rust damages, technical problem that machine tool accuracy is low.
For solving the problems of the technologies described above, the utility model embodiment discloses a kind of grinding machine hydraulic system, comprise lathe bed, workbench, oil cylinder, piston head, piston rod and y-type seal ring, described workbench is fixed on described lathe bed, described oil cylinder is located in described lathe bed, described piston head to be located in described oil cylinder and to be connected with described piston rod, described piston rod one end is connected with described piston head, the other end stretches out and runs through described lathe bed from described oil cylinder, and described y-type seal ring is arranged on the junction of oil cylinder and piston rod and is socketed with described piston rod.
In a kind of preferred embodiment of the grinding machine hydraulic system provided at the utility model, the junction of described piston rod and described lathe bed is provided with sealing ring.
In a kind of preferred embodiment of the grinding machine hydraulic system provided at the utility model, described workbench is provided with guide rail.
In a kind of preferred embodiment of the grinding machine hydraulic system provided at the utility model, described piston head and described piston rod form T-shaped structure.
Compared to prior art, two rods that lathe is passed in and out oil cylinder by the utility model change single rod into, the chance of decrease oil cylinder leakage of oil, leaking, the O RunddichtringO of described piston rod and described oil cylinder junction changes y-type seal ring into, its structure is more stable, not easily deform, when running into hot-air, the support sealing property of y-type seal ring is better, and y-type seal ring can avoid dust to enter in the gap of piston rod and oil cylinder, decrease the ring wear that dust causes, and then extend the service life of lathe.Therefore, grinding machine hydraulic system of the present utility model has good sealing property, oil cylinder leakage of oil, minimizing of leaking, and makes the guide rail on workbench not be subject to oil cylinder leakage of oil and corrosion and damages, thus ensure that the precision of lathe.
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 existing grinding machine hydraulic system;
Fig. 2 is the structural representation of the grinding machine hydraulic system that the utility model provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model mainly improves on the basis of existing M147 model grinding machine hydraulic system, and two rods lathe being passed in and out oil cylinder change single rod into, and change O RunddichtringO into y-type seal ring.Particularly, referring to Fig. 2, is the structural representation of the grinding machine hydraulic system that the utility model provides.Described grinding machine hydraulic system 2 comprises lathe bed 21, workbench 22, oil cylinder 23, piston head 24, piston rod 25 and y-type seal ring (not shown).Described workbench 22 is fixed on described lathe bed 21, described oil cylinder 23 is located in described lathe bed 21, described piston head 24 to be located in described oil cylinder 23 and to be connected with described piston rod 25, itself and described piston rod 25 form T-shaped structure, described piston rod 25 one end is connected with described piston head 24, the other end stretches out and runs through described lathe bed 21 from described oil cylinder 23, and described y-type seal ring is arranged on the junction of oil cylinder 23 and piston rod 25 and is socketed with described piston rod 25.
Further, described workbench 22 is also provided with guide rail.
Further, described piston rod 25 is provided with sealing ring with the junction of described lathe bed 21.
Compared to prior art, two rods that lathe is passed in and out oil cylinder by the utility model change single rod into, the chance of decrease oil cylinder leakage of oil, leaking, the O RunddichtringO of described piston rod and described oil cylinder junction changes y-type seal ring into, its structure is more stable, not easily deform, when running into hot-air, the support sealing property of y-type seal ring is better, and y-type seal ring can avoid dust to enter in the gap of piston rod and oil cylinder, decrease the ring wear that dust causes, and then extend the service life of lathe.Therefore, grinding machine hydraulic system of the present utility model has good sealing property, oil cylinder leakage of oil, minimizing of leaking, and makes the guide rail on workbench not be subject to oil cylinder leakage of oil and corrosion and damages, thus ensure that the precision of lathe.
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.
