Description
Technical field
The utility model belongs to technical field of automobile accessories, more particularly to gas engine part technical field, and in particular to
A kind of valve collet mechanism.
Background technology
Valve collet is a parts of Valve System of Internal Combustion Engine, and effect is to connect valve and valve spring upper seat,
Transmit the power needed for valve opening and closing and movement.Prior art operation principle is：Pass through valve tail portion between valve and valve collet
External cylindrical surface and valve collet inner headed face coordinate, and by laterostigmatal groove and the boss axially position on valve collet and pass
Graduating power is coordinated between valve collet and valve spring upper seat by locker male cone (strobilus masculinus) and spring base taper hole.Traditional valve lock
Be clipped in assembled state when, between the valve and cotter seat that make formed rigid connection and can not good passing power,
Valve opening and the response of closing are poor；And exist between traditional valve collet lower face and the lower face at the spring seat of honour
There is the white space not surrounded by boss in white space, valve collet top and bottom, these white spaces are easy product
Carbon, carbon granules, which enters contact surface, to generate abrasion to contact surface, and wear point will produce stress concentration when serious.
Utility model content
For deficiency existing for valve collet mechanism in the prior art, the purpose of this utility model is to provide a kind of structures
Simply, light-weight, be not likely to produce carbon distribution, valve opening and the fast valve collet mechanism of the response of closing.
To achieve the above object, the technical solution of the utility model is：A kind of valve collet mechanism, including valve, valve
Locker, the spring seat of honour and valve spring, the lower end of the valve collet is concordant with the lower end at the spring seat of honour, the valve lock
Folder is to fit closely with the valve.
Further, the valve collet includes coniform locker ontology, and three ring-types are equipped in the locker ontology
In boss, form cricoid groove between the boss.
Further, the cross section of the groove is to the arc-shaped of locker body recess.
Further, the cross section of the groove is waveform.
Further, the cross section of the boss is complete semicircular arc or arc-shaped less than semicircle.
Further, the boss includes boss I, boss II, boss III, the upper surface of the boss I and the locker
The upper surface of ontology is concordant, and the lower face of the boss III is concordant with the lower face of locker ontology.
Further, the inner surface at the spring seat of honour is the cone coordinated with the valve collet outer surface.
Further, the spring seat of honour is equipped with limit protrusion, and the limit protrusion lower face is plane, the spring pocket
It is connected on the spring seat of honour, the limit protrusion lower face is contacted with the spring.
The advantages of using technical solutions of the utility model for：
1. be arranged the lower end of valve collet is concordant with the lower end at the spring seat of honour, solve due to valve collet lower end with
There are problems that white space between the lower end of the spring seat of honour and be easy carbon distribution, dust accumulation, valve collet is entered so as to avoid carbon granules
With the contact surface between the spring seat of honour, contact surface is caused to generate the phenomenon that wearing.
2. setting the cross section of groove to waveform or being set as, to the arc-shaped of locker body recess, alleviating gas
The weight of grille clip realizes light-weight design, improves the response of valve opening and closing.
3. being arranged the upper surface of boss I is concordant with the upper surface of locker ontology, lower face and the locker ontology of boss III
Lower face be concordantly arranged, when, it is therefore prevented that between valve collet and valve the phenomenon that carbon distribution, dust accumulation；Second is that due to without
It is higher by the part of I upper surface of boss and is higher by the part of III lower face of boss, avoid the portion being higher by when manufacturing valve collet
The phenomenon that door easy tos produce stress concentration, to increase the structural strength of valve collet, simplifies the process processed of valve collet.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments：
Fig. 1 is the overall structure diagram that the utility model is valve collet mechanism.
Label in above-mentioned figure is respectively：1. valve；2. valve collet；21. locker ontology；22. boss；221. boss I；
222. boss II；223. boss III；23. groove；3. the spring seat of honour；31. limit protrusion；4. valve spring.
Specific implementation mode
As shown in Figure 1, a kind of valve collet mechanism, including valve 1, valve collet 2, the spring seat of honour 3 and valve spring 4,
The lower end of valve collet 2 is concordant with the lower end at the spring seat of honour 3, and valve collet 2 is to fit closely with valve 1.By valve collet 2
Lower end is concordant with the lower end at the spring seat of honour 3 to be arranged, and is solved due to being deposited between 3 lower end of 2 lower end of valve collet and the spring seat of honour
The problem of white space is easy carbon distribution, dust accumulation, entered between valve collet 2 and the spring seat of honour 3 so as to avoid carbon granules
Contact surface causes contact surface to generate the phenomenon that wearing.
Above-mentioned valve collet 2 includes coniform locker ontology 21, sets that there are three the boss in cyclic annular in locker ontology 21
22, the cross section of boss 22 is complete semicircular arc or arc-shaped less than semicircle.Cricoid groove is formed between boss 22
23, the cross section of groove 23 is that arc-shaped or groove 23 the cross section being recessed to locker ontology 21 is waveform；Because of gas
The cooperation of grille clip 2 and valve 1 is mainly positioned and is transmitted power by boss 22, and the effect of groove 23 can be ignored, from light
It can set the cross section of groove 23 to waveform from the point of view of quantization or be set as the circle being recessed to locker ontology 21
Arc alleviates the weight of valve collet 2.
Above-mentioned boss 22 includes boss I 221, boss II 222, boss III 223, upper surface and the locker ontology of boss I 221
21 upper surface is concordant, and the lower face of boss III 223 is concordant with the lower face of locker ontology 21.When, it is therefore prevented that valve collet 2
Between valve 1 the phenomenon that carbon distribution, dust accumulation；Second is that due to without be higher by I 221 upper surface of boss part and be higher by boss
The part of III 223 lower faces avoids the phenomenon that department being higher by when manufacturing valve collet 2 easy tos produce stress concentration, from
And the structural strength of valve collet 2 is increased, simplify the manufacturing process of valve collet 2.
The inner surface at the above-mentioned spring seat of honour 3 is the cone coordinated with 2 outer surface of valve collet, and the spring seat of honour 3 is equipped with limit
Position protrusion 31,31 lower face of limit protrusion are plane, and spring 4 is socketed in the spring seat of honour 3, inner ring and the spring seat of honour 3 of spring 4
Outer ring contacts, and guiding is played the role of in the spring seat of honour 3 to spring 4, and 31 lower face of limit protrusion is contacted with spring 4, limit protrusion
31 have limited position of the spring 4 on 1 axial direction of valve.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the improvement of the various unsubstantialities of technical solutions of the utility model progress is used, or without changing
Directly apply to other occasions by the design of the utility model and technical solution, the scope of protection of the utility model it
It is interior.
