Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a novel simple pipeline quick on-off sealing structure belongs to mechanical technical field. BACKGROUND
[0002] At present, the vertical and horizontal machine tools in mechanical industry all have multiple tool holders, in most cases, the oil way sealing effect is poor when changing tools, the oil way occupies larger space, the structure is more complex, and the effect of quick and practical is not achieved. CONTENT OF THE UTILITY MODEL
[0003] In order to overcome the insufficient of prior art, the utility model provides a novel simple pipeline quick on-off sealing structure, the structure solves the problem of poor oil way sealing during tool changing of machine tool, the oil way sealing effect is ideal, and is no longer limited by space and structure, the production cost is low, and the structure is simple.
[0004] The utility model discloses a novel simple pipeline quick on-off sealing structure, including compression spring, piston, cover, thickened sealing ring and positioning pin, the positioning pin is a hollow pin body, and the positioning pin is horizontally arranged, and one end of the positioning pin is fitted in the cavity of the tool holder, and the tool holder is installed on one side of the tool plate, and the tool holder is detachable structure, and the cavity in the tool holder and the oil way are communicated with the cavity of the tool plate and the oil way.
[0005] The compression spring is horizontally arranged and installed in the cavity of the tool plate, and the piston is penetrated into the compression spring, the cover is installed in the cavity of the tool plate and located on one side of the piston, the thickened sealing ring is installed in the cover, and the end of the positioning pin protruding from the tool holder is close to the thickened sealing ring.
[0006] The utility model has the advantages that the utility model solves the problem of oil seepage caused by poor oil way sealing during tool changing of machine tool, greatly improves the tool changing efficiency, and has simple structure, convenient and fast operation, ideal oil way sealing effect, and can be used in other similar structures requiring quick on-off sealing, such as ventilation pipeline or water pipeline.

[0012] As Figure 1 A new simple pipeline quick on-off sealing structure is shown in Fig. 2, which comprises a compression spring 1, a piston 2, a cover 3, a thickened sealing ring 4 and a positioning pin 5. The positioning pin 5 is a hollow pin body, and is horizontally arranged. One end of the positioning pin 5 is fitted into a cavity of a knife holder 6, and the knife holder 6 is installed on one side of a knife plate 7. The knife holder 6 is detachable, and the cavity of the knife holder 6 and an oil inlet pipeline 8 are communicated with the cavity of the knife plate 7 and the oil inlet pipeline 8. The other end of the positioning pin 5 protrudes from the knife holder 6 and is located in the cavity of the knife plate 7.
[0013] The compression spring 1 is horizontally arranged and fitted into the cavity of the knife plate 7, and the piston 2 penetrates into the compression spring 1. The cover 3 is fitted into the cavity of the knife plate 7 and is located on one side of the piston 2. The thickened sealing ring 4 is fitted into the cover 3, and the other end of the positioning pin 5 protruding from the knife holder 6 is close to the thickened sealing ring 4.
[0014] In use, when the knife plate 7 is in a state without the knife holder 6, the oil inlet pipeline 8 of the knife plate 7 is in a closed state, and no oil is discharged, i.e. the compression spring 1 pushes the piston 2 to move, and the piston stops when it reaches the cover 3. At this time, the front end of the piston 2 is just inserted into the inner hole of the thickened sealing ring 4 to form a sealing protection, and the oil is not overflowed. When the knife holder 6 is in a state of holding a knife, the positioning pin 5 on the knife holder 6 pushes the piston 2 to compress the compression spring 1, and the piston 2 is separated from the thickened sealing ring 4. The oil in the inside of the piston 2 is discharged into the cavity of the thickened sealing ring 4, and then enters the positioning pin 5 to reach the knife holder 6 to form a passage, so as to cool the knife holder 6.
