The invention discloses a cam shaft signal wheel and a manufacturing method thereof. The manufacturing method comprises the following steps that firstly, a signal wheel disc is pre-casted at the tail end of a cam shaft; secondly, according to the position requirement, tooth holes are machined in the surface or the end face of the signal wheel disc; thirdly, signal pieces are machined, and the signal pieces comprise protrusions which are used for installation; fourthly, the protrusions of the machined signal pieces are pressed into the tooth holes of the signal wheel disc in an interference mode by a pressing machine, and a signal wheel with an end face signal taking mode or a circumferential signal taking mode is obtained. The cam shaft signal wheel and the manufacturing method thereof have the advantages that the signal wheel is not needed to be big, the cost is greatly lowered, the arrangement position of the signal wheel is flexible, the arrangement position is not limited by the signal wheel assembling position, and the interchangeability is high.
Description
Technical field
The invention belongs to engine design field, specifically, relate to a kind of Novel pressure assembling structure camshaft signal wheel and manufacture method thereof.
Background technique
Camshaft signal is taken turns, and is that motor reads the critical component of camshaft-position signal, by the periodic signal reading signal wheel, signal emitter identifies that whether the relative position of camshaft and bent axle is correct, thus provides a signal foundation for the igniting of motor.
The design of traditional camshaft signal wheel, is on certain axle journal of camshaft, press-fit separately a signal wheel, is generally arranged in camshaft tail end, needs exploitation camshaft and signal wheel separately, and the exploitation separately of signal wheel, expensive.
Summary of the invention
The technical problem that the present invention solves is that signal wheel does not need independent exploitation, has huge advantage above cost, and solves signal wheel position problem flexibly.
The invention discloses the manufacture method of a kind of camshaft signal wheel, comprise the steps:
1) by the tail end of signal wheel disc precasting at camshaft;
2) according to status requirement, perforation is gone out in the surface Machining of signal wheel disc;
3) processing signal sheet, signal patch comprises the projection for installing;
4) the pressing machine interference that projects through of the signal patch processed is press fit in the perforation of signal wheel disc, obtains the signal wheel that end face gets aspect.
Also can process perforation at the end face of signal wheel disc, obtain the signal wheel that circumference gets aspect.
Wherein signal patch is two panels or four.
The invention also discloses camshaft signal wheel prepared by said method, it is from end face or the circumference number of winning the confidence.
The invention has the advantages that:
What 1, signal wheel did not need to do is too large, this to the loss of weight of signal wheel and material save provide a kind of may, cost reduces greatly;
2, the structure of signal teeth as required, can realize four teeth and bidentate signal wheel design exchange by the processing setting of signal teeth mounting-positioning holes, no longer needs because the change duplicate removal of calibration strategy signal wheel newly developed;
3, the position of signal wheel is flexible, no longer limits by signal wheel rigging position.

Embodiment
Below in conjunction with accompanying drawing, the present invention is specifically described.
As Figure 1-4, the manufacture of signal wheel comprises the steps:
1, by the tail end of signal wheel disc 3 precasting at camshaft 2;
2, according to status requirement, perforation 4 is gone out in the surface Machining of signal wheel disc 3;
3, processing signal sheet 5 as required, can be four teeth as shown in Figure 3, also can be two teeth, or other.As shown in Figure 3, signal patch 5 comprises the projection 6 for installing;
4, the projection 6 of the signal patch 5 processed is press fit in the perforation 4 of signal wheel disc 3 the application by pressing machine interference, obtains the signal wheel that the end face shown in Fig. 4 gets aspect.
Also can process perforation 4 in the circumferential end faces of signal wheel disc 3, press-fit signal sheet 5, obtain the signal wheel that the circumference shown in Fig. 5 gets aspect.
Signal wheel, in the angular positioning of circumference, carrys out location and installation according to camshaft circumference positioning boss.Thus solve the problem that signal patch accurately installs.
1, signal wheel cost advantage and weight advantage:
The signal wheel that the application mentions, is made up of camshaft precasting signal panel and signal patch, can makes the disk needing size as required, then process corresponding signal patch mounting hole, last press-fit signal sheet.It is very little that the exterior contour of such signal wheel can do according to actual needs, and what bring is the reduction of weight own and the reduction of cost of material of part.
2, the flexibility of signal wheel design:
Traditional signal wheel design is the input according to EFI producer, specifies the signal wheel adopting what structure, i.e. two teeth or four toothings.Different EFI producer, its calibration strategy is different, therefore getting that signal may the be caused take turns difference that aspect and the signal number of teeth require and again develop signal and take turns.
The press mounting structure signal wheel that the application mentions, the structure of signal teeth can be as required, four teeth and bidentate signal wheel design exchange can be realized by the processing setting of signal teeth mounting-positioning holes, no longer need because the change duplicate removal of calibration strategy signal wheel newly developed.
3, the flexibility of signal wheel layout:
Traditional signal wheel design needs to develop camshaft and independent signal wheel respectively, and signal wheel can only be arranged in the both ends of the surface of camshaft, usually in the majority to be arranged in ear end face.If signal wheel is arranged in camshaft intermediate portion, signal wheel profile will become very large, because the axle journal interference of signal wheel is contained on camshaft, its journal diameter must be greater than cam profile diameter, so the position of signal wheel is limited.
The press mounting structure signal wheel mentioned herein, will change this situation, and signal wheel disc precasting is at any position of camshaft, and the signal patch that signal wheel disc is processed needs installs aperture, then signal patch interference is press-fited.Namely the position of signal wheel is no longer limited on camshaft.
4, the popularity of application
The press mounting structure signal wheel that the application mentions, not only can be applied in the structure of the end face number of winning the confidence, also can be applicable in the structure of the circumference number of winning the confidence.The mode taked is all roughly the same, and namely install aperture at the requirement position processing signal sheet of signal panel circumference, then be fitted on signal panel by pressing machine by signal patch, the location of angle direction can position according to the both ends of the surface of signal panel.
