Abstract
The invention discloses a ball-swelling type high-pressure end cap, which comprises an end cap, wherein the end cap is integrally in a cylindrical structure; one end of the end cap is in a taper-shaped structure; the outer wall of the end cap is provided with one circle of groove; back teeth are evenly arranged in the groove; the vertex angles of the back teeth are level with the outer wall of the end cap; the other end of the end cap is drilled with an expansion hole; the internal diameter of the expansion hole and an extrusion piece are in interference fit. The ball-swelling type high-pressure end cap disclosed by the invention has the advantages of simple structure and artful conception, the end cap is radially expanded by the principle of pressure expansion so as to be more tightly combined with a hole in a workpiece, so that the sealing effect is good, no phenomena of loosening or leakage are in the presence if the ball-swelling type high-pressure end cap is operated for a long time, and the service life of the ball-swelling type high-pressure end cap is greatly prolonged.
Description
Technical field
What the present invention relates to is that spare parts processing machinery is manufactured field, is specifically related to a kind of ball formula high pressure plug that rises.
Background technique
What common high pressure plug adopted mostly in the market is the means of fixation that spiral spins, the key of its sealability is rubber ring, and along with service time one is long, traditional rubber ring there will be the phenomenon that is oxidized hardening, thereby reduce its overall sealing, had the problem of easily leaking.
Summary of the invention
The object of the invention is to provide a kind of ball formula high pressure plug that rises, and it can solve existing problem in background technique effectively.
In order to solve existing problem in background technique, it comprises plug, this plug entirety is column construction, its one end is cone structure, described plug outer wall is provided with a circle groove, in this groove evenly distributed have set one's teeth on edge, described in the drift angle of setting one's teeth on edge flush with the outer wall of plug, the other end of described plug is drilled with inflation port, the external diameter interference fit of the internal diameter of this inflation port and crowded part.
The outer end of described inflation port mills out and the concentric fixed hole communicating of inflation port, and the degree of depth of this fixed hole milling out terminates in the rear end of groove, and the slightly larger in diameter of described fixed hole is in the diameter that squeezes part.
Between described inflation port and fixed hole, be provided with chamfering.
The front end of described inflation port is drilled with the concentric cone shape hole communicating, and the bottom surface of this cone shape hole terminates in the front end of groove.
The axial length of described inflation port is consistent with the length of groove.
Described crowded part is spherical structure.
Described crowded part entirety is columniform structure, and its end face is hemisphere.
Owing to having adopted above technological scheme, the present invention has following beneficial effect: simple in structure, be skillfully constructed, utilize tightr that the principle of pressure expansion makes that the hole of plug radial expansion on workpiece be combined, sealing effect is better, and can there is not loosening phenomenon of leaking in long time running, increased greatly its working life yet.
Accompanying drawing explanation
In order to be illustrated more clearly in the present invention, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that squeezes part in the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described.
Referring to Fig. 1, this embodiment is to be achieved by the following technical solutions, it comprises plug 1, this plug 1 entirety is column construction, and its one end is cone structure, and described plug 1 outer wall is provided with a circle groove, in this groove evenly distributed have set one's teeth on edge 2, described 2 the drift angle of setting one's teeth on edge flushes with the outer wall of plug 1, and the other end of described plug 1 is drilled with inflation port 3, the external diameter interference fit of the internal diameter of this inflation port 3 and crowded part 4.
In order to prevent squeezing part 4 knocking in the process of inflation port 3, there is squeezing the phenomenon that part flies out and hurts sb.'s feelings, the outer end of described inflation port 3 mills out and the concentric fixed hole communicating 5 of inflation port 3, and the degree of depth of the fixed hole 5 that this mills out terminates in the rear end of groove, and its slightly larger in diameter is in the diameter that squeezes part 4.
Between described inflation port 3 and fixed hole 5, be provided with chamfering, be convenient to squeeze part 4 and can enter into smoothly in inflation port 3.
Described crowded part 4 is spherical structure.
Be the structure of cylindricality referring to crowded part 4 entirety described in Fig. 2, its end face is hemisphere.
The front end of described inflation port 3 is drilled with the concentric cone shape hole communicating 6, and the bottom surface of this cone shape hole 6 terminates in the front end of groove, and the crowded part 4 that can make to enter in inflation port 3 can stop therein, increases the area of radial expansion on plug 1 simultaneously.
The described axial length of inflation port 3 and the length of groove are consistent, can make all on groove set one's teeth on edge and 2 completely press and be embedded in the hole wall of workpiece, have increased greatly its overall sealing effect and constant intensity.
Working principle and operating process below in conjunction with accompanying drawing to this embodiment are further elaborated:
To squeeze part 4 puts in fixed hole 5, startup drift will squeeze part 4 and inwardly impact, owing to being interference fit between crowded part 4 and inflation port 3, be squeezed into crowded part in inflation port 3 by 2 radial expansions to the periphery of setting one's teeth on edge that are arranged in groove, and 2 the drift angle of setting one's teeth on edge is pressed and is embedded on the hole wall of workpiece, thereby realize the object of inclusion seal.
Owing to having adopted above technological scheme, this embodiment has following beneficial effect: simple in structure, be skillfully constructed, utilize tightr that the principle of pressure expansion makes that the hole of plug radial expansion on workpiece be combined, sealing effect is better, and can there is not loosening phenomenon of leaking in long time running yet, increase greatly its working life, can be widely used in hydraulic pressure, pneumatic element, valve group, oil cylinder, cylinder, the shutoff of unnecessary fluid passage, difference and existing bolt, the variety of ways such as welding or pin are stifled, be particularly suitable for the shutoff that internal pressure is higher.
Finally it should be noted that: above embodiment only, in order to technological scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art should be appreciated that its technological scheme that still can record aforementioned each embodiment modifies, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technological scheme.
