Abstract
The invention discloses an anti-crushing device comprising an outer circle used for supporting a camshaft and a supporting seat provided with two V-shaped grooves along the axis of the camshaft. The bottoms of the V-shaped grooves are further provided with rectangular grooves. The device further comprises a brass sleeve used for coating the outer circle of the camshaft; the brass sleeve comprises a first sleeve unit used for coating one part of the outer circle of the camshaft and a second sleeve unit used for coating the other part of the outer circle of the camshaft; the thickness of the brass sleeve ranges from 2mm to 6mm. By the aid of the device, the outer circle of the camshaft can be prevented from being crushed effectively, and the qualified rate of products can be increased.
Description
Technical field
The present invention relates to mechanical engineering technical field, particularly one is anti-weighs device wounded.
Background technology
Along with the fast development of China's economic construction, market increases day by day for various types of anti-demand weighing device wounded.
We know, for the processing of camshaft, often first carry out fine finishining to two cylindricals of cam, and then carry out Milling Process to the end face of cam.
In the prior art, when we carry out Milling Process to the end face of cam, usually need with two of cam cylindricals for benchmark; Therefore, when carrying out clamping to two cylindricals of cam, thrust needs enough large, and so, two cylindricals of the very easy cam fine finishining completed weigh wounded, affect the qualification rate of product.
Therefore, how solving qualification rate low is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The object of this invention is to provide one to prevent weighing device wounded, this prevents that weighing device wounded can solve the low problem of product percent of pass.
For achieving the above object, the invention provides and a kind of anti-weigh device wounded, the described anti-device that weighs wounded comprises and having in order to the cylindrical of supporting cam wheel axle, the supporting seat along the V-shaped groove of the axis of described camshaft.
Preferably, the bottom of the groove of described V-type is also provided with rectangular recess.
Preferably, the number of the groove of described V-type is two.
Preferably, the described anti-brass bushing weighing device wounded and also comprise the cylindrical wrapping up described camshaft.
Preferably, described brass bushing comprises second brass bushing of the first brass bushing of a part for the cylindrical wrapping up described camshaft and the another part in order to the cylindrical that wraps up described camshaft.
Preferably, the scope of the thickness of described brass bushing is between 2mm ~ 6mm.
Relative to above-mentioned background technology, provided by the inventionly anti-weigh device wounded, comprise the cylindrical that has in order to supporting cam wheel axle and along the supporting seat of the V-shaped groove of the axis of camshaft.That is, the cylindrical of the recess supports camshaft of the V-type on supporting seat is utilized; Because two sidewalls of the groove of V-type have certain angle, the pressure that the cylindrical that effectively can decompose camshaft produces when clamping is fastening; Therefore, this set can effectively prevent the cylindrical of camshaft from being weighed wounded, thus improves product percent of pass.
Accompanying drawing explanation
The anti-structural representation weighing the supporting seat of device wounded that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the anti-structural representation weighing the brass bushing of device wounded in Fig. 1;
Fig. 3 is the structural representation of the brass bushing in Fig. 2 when coordinating with the cylindrical of camshaft.
Detailed description of the invention
Core of the present invention is to provide one and prevents weighing device wounded, and this prevents that weighing device wounded can avoid the cylindrical of camshaft to be weighed wounded.
In order to make those skilled in the art understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the anti-structural representation weighing the supporting seat of device wounded that Fig. 1 provides for the embodiment of the present invention; Fig. 2 is the anti-structural representation weighing the brass bushing of device wounded in Fig. 1; Fig. 3 is the structural representation of the brass bushing in Fig. 2 when coordinating with the cylindrical of camshaft.
Provided by the inventionly anti-weigh device wounded, comprise the cylindrical that has in order to supporting cam wheel axle and along the supporting seat 1 of the V-shaped groove of the axis of camshaft.
That is, the cylindrical of the recess supports camshaft of the V-type on supporting seat 1 is utilized; Because two sidewalls of the groove of V-type have certain angle, the pressure that the cylindrical that effectively can decompose camshaft produces when clamping is fastening; Therefore, this set can effectively prevent the cylindrical of camshaft from being weighed wounded, thus improves product percent of pass.
In addition, we can also be provided with rectangular recess in the bottom of the groove of V-type.
Adopt this sample loading mode, can firm for the cylindrical of camshaft is positioned in the groove of V-type, the clamping force that the cylindrical that can reduce camshaft like this bears, thus more effectively avoid the cylindrical of camshaft to be weighed wounded, thus improve product percent of pass.
In addition, the number of the groove of V-type can also be set to two by us.
According to practical experience, general camshaft has two place's cylindricals, on supporting seat 1, be therefore provided with the groove of two V-types, in order to supporting cam wheel axle; So, camshaft can be positioned in the groove of V-type.
Certainly, the groove of two V-types according to processing technology, can also be positioned on same level line by we; That is, when camshaft is placed on the groove of V-type, the axis horizontal of camshaft, is so just conducive to processing.
Certainly, we also according to different processing technologys, can arrange the groove that two are not in the V-type on same level line; Repeat no more herein.
In addition, weigh device wounded for anti-, we can also be provided with the brass bushing 2 of the cylindrical wrapping up described camshaft.
Obviously, we utilize brass bushing 2 to be wrapped up by the cylindrical of camshaft, are then positioned in the groove of V-type by the cylindrical of camshaft; So, brass bushing 2 can effectively avoid the cylindrical of camshaft to be weighed wounded, thus improves product percent of pass.
In addition, brass bushing can be divided into two parts by us; Second brass bushing of the first brass bushing of a part for the cylindrical wrapping up described camshaft and the another part in order to the cylindrical that wraps up described camshaft respectively.
That is, the first brass bushing can be wrapped in the cylindrical of camshaft by us, and now the first brass bushing can not wrap the cylindrical of camshaft completely; Then the second brass bushing is utilized to be wrapped by the remainder of the cylindrical of camshaft; Utilize the first brass bushing and the second brass bushing to be wrapped completely by the cylindrical of camshaft like this, thus avoid the cylindrical of camshaft to be weighed wounded, thus improve product percent of pass.
In addition, the scope of the thickness of brass bushing can be arranged between 2mm ~ 6mm by we.
According to practical experience, the brass bushing of 2mm thickness is adopted can effectively to avoid the cylindrical of camshaft to be weighed wounded; Certainly, we also can adopt the brass bushing of 6mm thickness, repeat no more herein.
Certainly, the diameter of brass bushing can arrange different numerical value according to the outer diameter of a circle of camshaft, repeats no more herein.
Prevent that weighing device wounded is described in detail to provided by the present invention above.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
