Abstract
The invention discloses an oil cylinder closing-up structure of a shock absorber. Four pressing points are punched at the end port of an oil cylinder, and are formed by the bending of partial cylinder wall at the end port towards the oil cylinder; a punching gasket which is used for assisting the formation of the pressing points and preventing an oil seal from deforming in punching the pressing points is arranged between the pressing points and the oil seal; and the closing-up structure replaces a nut spin riveted structure adopted by the existing shock absorber generally. Compared with the original nut spin riveted structure, the four-point closing-up structure has the advantages that: 1. the four-point closing-up state has good reliability, quality state is stable, and the using requirements of the shock absorber in batch can be met; 2. the processing technology of parts is simple and convenient, the nut spin riveted structure is changed into the four-point closing-up structure, the special nut is cancelled, the punching gasket is adopted, and the screw threads are not processed on the oil cylinder any more; and the technology is easier to realize; and 3. the labor intensity is small, the operation is simple, and the production efficiency is high.
Description
Technical field
The present invention relates to the vibration damper technical field, be specifically related to the sealing technique of shock absorber fluid tube port.
Background technique
As shown in Figure 3, present vibration damper generally adopts nut to revolve the port one 1 sealing mode of riveting structure as oil tube 1, and it is with the proper functioning and the sealing that guarantee vibration damper in the oily cartridge modules of screw-in such as oil sealing 2, seal ring, guider with specialized nut 5 (M66X1.5) that the nut that my company adopts revolves the riveting structure; Because the screw thread (M66X1.5) of specialized nut 5 is bigger; The processing of screw thread and operator screw very difficult in the vibration damper assembly process, and rely on operator's experience to determine whether to screw, if the meeting not in place of screwing causes vibration damper loosening; Cause leakage of oil and abnormal sound etc.; The quality fault that can't avoid personal factor to cause has influence on quality of product, and labor intensity is big simultaneously; Manufacturing efficiency is low, has restricted the large-scale production of this kind vibration damper.
Summary of the invention
Goal of the invention of the present invention provides a kind of shock absorber fluid tube closing in structure, the above problem that exists with the port closed structure that solves existing shock absorber fluid tube.
For reaching the foregoing invention purpose; The technological scheme that the present invention adopted is: proposed a kind of shock absorber fluid tube closing in structure; It is characterized in that: the port punching press at the oil tube has plural pressure point, and said pressure point is that the part barrel of port forms to oil tube complications.
According to shock absorber fluid tube closing in structure of the present invention, it is characterized in that: be provided with the punching press packing ring that is used for auxiliary pressure point moulding and avoids oil sealing when the punching press pressure point, to be out of shape between said pressure point and the oil sealing.
According to shock absorber fluid tube closing in structure of the present invention, it is characterized in that: said pressure point circumferentially evenly distributes port.
According to shock absorber fluid tube closing in structure of the present invention, it is characterized in that: said pressure point is two to six.
According to shock absorber fluid tube closing in structure of the present invention, it is characterized in that: said pressure point () is four.
Four check and accept mouth structure and former nut revolves the advantage that the riveting structure is compared:
1,4 closing in state good reliabilitys, quality state is stable, can satisfy the vibration damper usage requirement in batches;
2, parts machining process is easy, nut is revolved the riveting structure change four into and check and accept mouth structure, has cancelled specialized nut, uses the punching press packing ring instead, machining screw no longer on the oil tube.Technology more is prone to realize;
3, labor strength is little, and is simple to operate, and manufacturing efficiency is high.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that K among Fig. 1 is to view;
Fig. 3 is existing oil tube port closed structure.
Wherein, 1, oil tube; 11, port; 2, oil sealing; 3, punching press packing ring; 4, pressure point; 5, nut.
Embodiment
Do below in conjunction with the accompanying drawing specific embodiments of the invention and to describe in detail.
Shock absorber fluid tube closing in structure as illustrated in fig. 1 and 2 has plural pressure point 4 oily 1 port one 1 place punching press, and the part barrel that said pressure point 4 is port one 1 place is to the 1 tortuous formation of oil tube.
For auxiliary pressure point 4 moulding with avoid oil sealing 2 to be out of shape when the punching press pressure point 2, also be provided with a slice punching press packing ring 3 between said pressure point 4 and the oil sealing 2.
Though auxiliary pressure point 4 moulding with avoid oil sealing 2 when punching press pressure point 2, be out of shape pressure point 4 at three or when above, though also can reasonable fixed oil seal 2 parts such as grade in circumferential uneven distribution, but still preferred pressure point 4 is in the circumferentially even distribution of port one 1.
Said pressure point 4 can play fixation when being two, can arrive ideal effect at three to six.But it is ideal from economy and four of machining angles.
Vibration damper four is checked and accepted the mouth structure working principle: after the operator assembles punching press packing ring, oil sealing, seal ring, guider, oily cartridge module etc. successively vibration damper is placed on use special closing-in mould on the press machine; Under certain pressure, oily cartridge module end face is extruded four pressure points and be pressed on the punching press packing ring, the axial motion of control Assembly part.To satisfy the vibration damper usage requirement.
Four check and accept mouth structure and former nut revolves the advantage that the riveting structure is compared:
1,4 closing in state good reliabilitys, quality state is stable, can satisfy the vibration damper usage requirement in batches;
2, parts machining process is easy, nut is revolved the riveting structure change four into and check and accept mouth structure, has cancelled specialized nut, uses the punching press packing ring instead, machining screw no longer on the oil tube.Technology more is prone to realize;
3, labor strength is little, and is simple to operate, and manufacturing efficiency is high.
The present invention is not limited to above-mentioned instance, in claims of the present invention institute restricted portion, and various distortion that those skilled in the art can make without creative work or revise the protection that all receives this patent.
