However, in the
Therefore, the present invention has been devised to solve the above problems, it is possible to prevent the phenomenon that the rust generated in the sensing hole is filled with the sensing hole even when rust occurs in the combined portion of the tone wheel in the rotor, and also reduce the mold cost and manufacturing cost and production time The production method and manufacturing apparatus and manufacturing method of the vehicle tone wheel which improved the precision by reducing the gap between the indentation part and the sensing part, while maintaining the constant gap of the sensing hole and improving the productivity by shortening the productivity and material waste. The purpose is to provide a vehicle tone wheel manufactured by.
Method for producing a tone wheel of the present invention for achieving the above object, the step of manufacturing a raw material connected to the raw material and the press-in portion protruded vertically from the raw material; Separating the disc from the material and then processing an outer edge of the disc to produce a plurality of sensing holes arranged radially around the indentation; Manufacturing the ton wheel of the finished product having a sensing part in close contact with the outer circumferential surface of the indentation part by processing the disc in the same direction as the protruding direction of the indentation part with respect to the boundary of the disc and the indentation part; It is done.
In addition, the manufacturing method of the tone wheel according to the present invention comprises the steps of manufacturing a raw material connected to the raw material and the press-in portion protruded vertically from the raw material; Separating the disc from the material and then processing an outer edge of the disc to produce a plurality of sensing holes arranged radially around the indentation; Manufacturing the sensing part in close contact with the outer circumferential surface of the press-fitting part by bending the disc about the boundary portion between the disc and the press-fitting part in the same direction as the projecting direction of the press-fitting part; And a post-processing step of restoring an interval (pitch) of the sensing hole deformed in the manufacturing step of the sensing unit at a predetermined interval.
In addition, the manufacturing method of the tone wheel according to the present invention comprises the steps of manufacturing a raw material connected to the raw material and the press-in portion protruded vertically from the raw material; Separating the disc from the material and then processing an outer edge of the disc to produce a plurality of sensing holes arranged radially around the indentation; Manufacturing the sensing part in close contact with the outer circumferential surface of the press-fitting part by bending the disc about the boundary portion between the disc and the press-fitting part in the same direction as the projecting direction of the press-fitting part; And a post-processing step of removing the gap between the press-fit part and the sensing part to improve the precision after manufacturing the sensing part.
In addition, the tone wheel of the present invention is manufactured by using the above-described manufacturing method, the press-fitting portion is pressed and coupled to the rotating body; And a plurality of sensing holes provided at equal intervals along the circumferential direction while being formed at one end of the indentation part to be in close contact with the outer circumferential surface of the indentation part.
In addition, the apparatus for manufacturing a tone wheel according to the present invention includes a disc and a press for vertically protruding from the disc and a mold for processing a plurality of sensing holes in the outer edge of the disc; And a bending mold for manufacturing a ton wheel of a finished product having a sensing part in close contact with an outer circumferential surface of the press-fitting part by bending the disc having the sensing hole formed therein in the protruding direction in a state where the press-fitting part is fixed. It is done.
When the tone wheel according to the present invention is installed and used in the rotating body, even if rust occurs in the rotating body, the rust generated in the rotating body is blocked by the indentation part, thereby making it impossible to move to the sensing unit, thereby causing rust generated in the rotating body. Since the phenomenon of filling the sensing hole is prevented, the tone wheel of the present invention has an advantage that it can always exhibit its function even if it is used for a long time regardless of rust generated in the rotating body, and thus the tone wheel of the present invention increases service life and improves durability. There is an effect that can be planned.
In addition, the tone wheel of the present invention is not composed of the press-fitting part and the sensing part are manufactured as a separate product, and then assembled together. In addition, it is possible to improve productivity by shortening the production time, and furthermore, there is an effect of greatly reducing unnecessary waste of materials.
