Abstract

The invention discloses an auxiliary hole plug of an engine. The auxiliary hole plug comprises a conical plug body and a plurality of sealing grooves. The sealing grooves are peripherally formed along the outer peripheral face of the plug body to separate the plug body into a plurality of sealing rings in contact with the inner peripheral faces of the auxiliary holes of the engine. Due to the fact that the auxiliary hole plug is conical and the rounded grooves are rolled in the outer peripheral face of the auxiliary hole plug and filled with sealing glue during assembling, good airtightness between the plug and the holes is achieved, and the plug is less prone to loosening, anti-vibration and anti-leakage.

Description

The auxiliary hole of motor stops up
Technical field
The present invention relates to engine art, particularly a kind of auxiliary hole of motor stops up.
Background technique
The casting process hole such as casting cylinder block, cylinder head of motor is general employing plug for seal now, and stopping up with coordinating of auxiliary hole is interference fit.Fig. 1 shows the main TV structure of present obstruction, and Fig. 2 is the sectional structure schematic diagram of the A-A direction of Fig. 1.As depicted in figs. 1 and 2, stop up now 11 for cylindrical structure, outer circumferential face does not have tapering, and bottom surface offers the axially upwardly extending cylindrical counterbore 12 of stepping down.
While stopping up with auxiliary hole interference fit, be cylindrical structure owing to stopping up 11, its outer circumferential face does not have tapering, and sometimes because of engine luggine, cold and hot variation, easily results in blockage and get loose, poorly sealed with auxiliary hole, and auxiliary hole is easily leaked.
The information that is disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Summary of the invention
The object of the present invention is to provide a kind of auxiliary hole of simple and reasonable motor to stop up, the auxiliary hole of this motor stops up as cone blocking, and on its outer circumferential face, roll out fillet groove, when assembling, the fillet groove in cone blocking is put into sealing glue, make to stop up with hole sealing better, be difficult for getting loose, anti-vibration, anti-leak.
For achieving the above object, the auxiliary hole that the invention provides motor stops up, and comprising: stop up body, it is taper; And multiple-sealed groove, offer along the outer circumferential face circumferential direction of described obstruction body, the outer circumferential face of described obstruction body is separated into the multiple-sealed ring contacting with the auxiliary hole inner peripheral surface of motor.
Preferably, in technique scheme, the tapering that stops up the outer circumferential face of body is 2 °-5 °.
Preferably, in technique scheme, seal groove is the twice that are arranged in parallel.
Preferably, in technique scheme, two seals groove is distributed in respectively the third-class office of described obstruction body outer circumferential face.
Preferably, in technique scheme, seal groove is fillet groove, and this fillet groove is that roll extrusion forms.
Preferably, in technique scheme, the small end of cone blocking body offers the cylindrical counterbore of stepping down axially extending to large end.
Compared with prior art, the present invention has following beneficial effect: the auxiliary hole of this motor stops up as cone blocking, and on its outer circumferential face, roll out fillet groove, when assembling, the fillet groove in cone blocking is put into sealing glue, make to stop up with hole sealing better, be difficult for getting loose, anti-vibration, anti-leak.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of embodiment.
Unless separately there is other clearly to represent, otherwise in whole specification and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 3 and Figure 4, the concrete structure stopping up according to the auxiliary hole of the motor of the specific embodiment of the invention comprises: stop up body 21 and be opened in the seal groove 22 of these obstruction body 21 outer circumferential faces, wherein, stop up body 21 and adopt cone structure, inserted auxiliary hole and its interference fit of motor by small end, the auxiliary hole stopping up with motor is sealed better, be difficult for getting loose, anti-vibration, anti-leak.In addition, in seal groove 22, coat sealing glue, further strengthened sealing and the vibration resistance of the auxiliary hole of obstruction and motor.
As shown in Figure 3, stop up body 21 for taper, the tapering of its outer circumferential face is 2 °-5 °.The outer circumferential face that stops up body 21 offers multiple-sealed groove 22 along circumferential direction, and multiple-sealed groove 22 is arranged in parallel, and seal groove 22 is for holding sealing glue.The seal groove 22 of the present embodiment is twice, be distributed in respectively the third-class office of stopping up body 21 outer circumferential faces, the outer circumferential face that stops up body 21 is separated into the three seals ring contacting with the auxiliary hole inner peripheral surface of motor, form many ring sealing configurations, to increase sealing and the vibration resistance stopped up with the auxiliary hole of motor.Preferably, seal groove 22 is fillet groove, and its diameter is d, and this fillet groove is that roll extrusion forms.
The Outside diameter of cone blocking body 21 is D, and in the time that diameter D is more than or equal to 10mm, the small end of cone blocking body 21 offers the cylindrical counterbore 23 of stepping down axially extending to large end; In the time that diameter D is less than 10mm, cone blocking body 21 adopts solid obstruction, does not offer the cylindrical counterbore 23 of stepping down (need not empty in the middle of stopping up) in cone blocking body 21.
The using method that the auxiliary hole of this motor stops up is: first, on the seal groove 22 of the outer circumferential face of cone blocking body 21, coat sealing glue, make the small end of cone blocking aim at the apertures, casting process hole such as motor casting cylinder block or cylinder head, cone blocking is pressed in auxiliary hole with hammer or pressure head.Because obstruction has 2 ° of-5 ° of taperings, stop up upper three ring pretensions, add to stop up on two roundlet chamfered grooves of cylindrical and coat sealing glue, therefore, cone blocking can be better with auxiliary hole sealing, be difficult for getting loose, anti-vibration, anti-leak.
To sum up, the auxiliary hole of this motor stops up as cone blocking, and on its outer circumferential face, rolls out fillet groove, when assembling, the fillet groove in cone blocking is put into sealing glue, makes obstruction better with hole sealing, be difficult for getting loose, and anti-vibration, anti-leak.
The aforementioned description to concrete exemplary of the present invention is in order to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.Exemplary embodiment is selected and the object described is to explain certain principles of the present invention and practical application thereof, thereby made those skilled in the art can realize and utilize various exemplary of the present invention and various selection and change.Scope of the present invention is intended to be limited by claims and equivalents thereof.
