Abstract
The invention discloses an output shaft mechanism for a vehicle starter. The output shaft mechanism comprises an output shaft and a pin, wherein the output shaft comprises a shaft body and a flange plate positioned on the tail part of the shaft body; a pin hole is formed in the flange plate; a groove is formed in the side surface of the pin; the pin is inserted into the pin hole; a bump and a positioning block which is matched with the groove are arranged on the inside wall of the pin hole; and the positioning block is clamped into the groove. The manufacturing method of the output shaft mechanism comprises the following steps of: A, preparing the output shaft and the pin, and forming the groove in the side surface of the pin; B, inserting the pin into the pin hole of the flange plate; and C, stamping the flange plate around the pin hole, so that a material on the flange plate is extruded into the groove to form the positioning block. The output shaft mechanism is molded by only inserting the pin into the pin hole and then performing stamping; part material on the flange plate is extruded into the groove to form the positioning block; the production process is simple and convenient; the molded structure is firm; and the pin does not fall essentially.
Description
Technical field
The present invention relates to output shaft mechanism of a kind of automobile starter and preparation method thereof.
Background technique
The output shaft mechanism of automobile starter generally comprises output shaft and pin, the flange plate that output shaft comprises axis body and is positioned at the axis body afterbody, and flange plate is provided with pin hole, and pin inserts in the pin hole and both interference connect.Its shortcoming that also exists is: when assembling, part precision is required greatly, require harsh to equipment and cutter, manufacture cost is very high, the fitness for purpose interference fit is controlled at and is of a size of 0.01 ~ 0.02mm for best, oversize or mistake young pathbreaker causes the bad of product, perhaps has potential risk, causes pin to come off in the later stage use.
Summary of the invention
Above-mentioned deficiency for the output shaft mechanism that overcomes automobile starter the invention provides a kind of output shaft mechanism that processes the automobile starter easy, that structure is more firm, and its preparation method is provided.
The technological scheme that the present invention solves its technical problem is: a kind of output shaft mechanism of automobile starter, comprise output shaft and pin, the flange plate that described output shaft comprises axis body and is positioned at described axis body afterbody, described flange plate is provided with pin hole, the side of described pin is provided with groove, described pin inserts in the described pin hole, and the inwall of pin hole be provided with the projection the positioning block adaptive with described groove, this positioning block snaps in the described groove.
Further, described positioning block fills up described groove.
Further, described groove is the recessed circle of a circle.
The preparation method of the output shaft mechanism of above-mentioned automobile starter comprises the following steps:
A. be ready to output shaft and pin, and process groove in the side of pin;
B. pin is inserted in the pin hole of flange plate;
C. around pin hole flange plate is carried out punching press, make the material on the flange plate clamp-on formation positioning block in the groove.
Beneficial effect of the present invention is: only pin need be inserted pin hole in moulding, carry out then getting final product towards riveting, production technology is easy, and shaped structures is more firm, and pin can not come off substantially.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
With reference to Fig. 1, a kind of output shaft mechanism of automobile starter, comprise output shaft and pin 1, the flange plate 3 that described output shaft comprises axis body 2 and is positioned at described axis body 2 afterbodys, described flange plate 3 is provided with pin hole, and the side of described pin 1 is provided with groove, and described pin inserts in the described pin hole, and the inwall of pin hole is provided with the positioning block 4 adaptive with described groove of projection, and this positioning block 4 snaps in the described groove.In the present embodiment, described groove is the recessed circle of a circle, and described positioning block fills up described groove.
The preparation method of the output shaft mechanism of above-mentioned automobile starter comprises the following steps:
A. be ready to output shaft and pin, and process groove in the side of pin;
B. pin is inserted in the pin hole of flange plate;
C. around pin hole flange plate is carried out punching press, make the material on the flange plate clamp-on formation positioning block in the groove.
The present invention only need insert pin hole with pin 1 in moulding, carries out then getting final product towards riveting, and the part material on the flange plate 3 is clamp-oned and formed positioning block in the groove, and production technology is easy, and shaped structures is more firm, and pin 1 can not come off substantially.
