Abstract

The utility model provides an air valve fastening part comprising a part body, in which is disposed a through-hole in an axial direction. The through-hole is cooperated with the air valve, and according to the design, at least one end of the part body can be a conical surface without the tip. Starting from the end surface of the conical surface, at least a notch is disposed in the side wall of the part body, and the notch can not break the side wall in the axial direction. By cooperating with related machines, the air valve fastening part provided in the utility model can be used to fix the valve conveniently, the further effective processing of the air valve can be realized, for example cutting or grinding.

Description

A kind of valve tightens up part

Technical field

The utility model relates to a kind of valve and tightens up part.

Background technology

Valve is a kind of vitals of engine, is responsible in engine input air specially and discharges waste gas after burning, from engine structure, is divided into inlet valve and exhaust valve; The effect of inlet valve is that air is sucked in the engine, and with the fuel mix burning, the effect of exhaust valve is that waste gas after burning is discharged and heat radiation; So the effect of valve in transmitter is conspicuous, in actual processing process, product had very high requirement; Need carry out many PROCESS FOR TREATMENT to valve,, valve carried out in the process of above-mentioned processing such as cutting or grinding or the like; Need fix valve, some modes of using in the prior art or be difficult to valve is tightened up cause in the processing procedure valve precision are caused damage; Can cause hard defects to valve table wall, reduce product quality, need improvement badly.

The utility model content

The utility model provides a kind of valve to tighten up part, can pass through cooperative mechanical, easily valve is tightened up, and valve is further handled.

The utility model solves the problems of the technologies described above through following technical scheme; The utility model proposes a kind of valve and tightens up part, comprises part noumenon, establishes a through hole that axially runs through in the said part noumenon; Said through hole cooperates with said valve; At least one end of said part noumenon is designed to not have the most advanced and sophisticated conical surface, is initial with said conical surface end face, offers at least one not with the breach of said side-wall shaft to disconnection at the sidewall of said part noumenon.

Preferably, said part noumenon two ends are designed to not have the most advanced and sophisticated conical surface, one group of corresponding two said breach of the said conical surface, and be uniformly distributed on the sidewall of said part noumenon corresponding to four said breach of two groups of said conical surfaces.

Preferably, the connecting portion of two groups of said conical surfaces is designed to the cylinder of sectional area less than said cone the maximum cross-section area.

Based on disclosing of above technical scheme, the utlity model has following beneficial effect:

The utility model is simple in structure, can pass through cooperative mechanical, easily valve is tightened up, and valve is further handled.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is embodiment 1 front view;

Fig. 2 is embodiment 1 side view;

1, first conical surface; 11, first breach; 2, second conical surface; 21, second breach; 3, connecting portion; 4, through hole; 5, valve.

The specific embodiment

Following embodiment 1 and Fig. 1-2 of combining is described further the utility model:

Embodiment 1

The utility model proposes a kind of valve and tightens up part, comprises part noumenon, establishes a through hole that axially runs through 4 in the part noumenon; Through hole 4 cooperates with valve 5, and the part noumenon left end is designed to first conical surface 1, and right-hand member is designed to second conical surface 2; First conical surface 1, second conical surface 2 all do not have most advanced and sophisticated, be initial with first conical surface 1, on the sidewall of part noumenon, offer two not with first breach 11 of side-wall shaft to disconnection; With second conical surface 2 is initial; Side-wall shaft is not uniformly distributed on the sidewall of part noumenon to 21, two group of first breach of second breach 11, two group of second breach 21 of breaking off offering two on the sidewall of part noumenon, the connecting portion 3 of first conical surface 1 and second conical surface 2 is designed to cylinder; First conical surface 1 is identical with the relevant parameter of second conical surface 2; First breach 21 is identical equally with the relevant parameter of second breach 21, and the sectional area of connecting portion 3 is less than the maximum secting area of first conical surface 1 and second conical surface 2, and this mode is economical with materials to the full extent.

As follows the use of the utility model is done further to set forth to the utility model:

Valve 5 is put into the through hole 4 that part noumenon is established; Part noumenon is put into the duct that is similarly pyramidal structure,, make the conical surface of part noumenon and duct inwall push through applying axial thrust to part noumenon; Part noumenon sidewall generation deformation, thus valve 5 fixed.

The utility model is not limited thereto embodiment, and the related realization assembly that is the basis with the utility model thought is all in the protection domain of the utility model.

Claims

1. a valve tightens up part; Comprise part noumenon, establish a through hole that axially runs through in the said part noumenon, said through hole cooperates with said valve; It is characterized in that; At least one end of said part noumenon is designed to not have the most advanced and sophisticated conical surface, is initial with said conical surface end face, offers at least one not with the breach of said side-wall shaft to disconnection at the sidewall of said part noumenon.

2. valve as claimed in claim 1 tightens up part; It is characterized in that; Said part noumenon two ends are designed to not have the most advanced and sophisticated conical surface, one group of corresponding two said breach of the said conical surface, and be uniformly distributed on the sidewall of said part noumenon corresponding to four said breach of two groups of said conical surfaces.

3. valve as claimed in claim 2 tightens up part, it is characterized in that, the connecting portion of two groups of said conical surfaces is designed to the cylinder of sectional area less than said cone the maximum cross-section area.
