Detailed Description
As shown in fig. 1 to 11, a riveting device for ensuring the pulling-out force requirement of a rocker arm comprises a supporting punch 1, a spring positioning pin 2, a support plate 3, a bottom plate 4, a first screw 5, a first cylindrical pin 6, a second screw 7, a second cylindrical pin 8, a first guide plate 9, a press-fitting punch 10, a third cylindrical pin 11, a second guide plate 12, a second bushing 13, a positioning block 14 and a first bushing 15; the supporting plate 3 is provided with a positioning hole and is positioned on the bottom plate 4 through the spring positioning pin 2, the supporting plate 3 is fixed on the bottom plate 4 through the cylindrical pin I6 and the screw I5, the supporting plate 3 is provided with a first through hole for placing the bushing I15, the bushing I15 is used for placing the supporting punch 1, the guide plate I9 is fixed on the upper surface of the supporting plate 3 through the screw II 7 and the cylindrical pin II 8, one end of the guide plate II 12 is hinged with the upper end of the guide plate I9 through the cylindrical pin III 11, the other end of the guide plate II 12 is provided with a second through hole, the bushing II 13 is placed in the second through hole, the bushing II 13 is used for placing the press-fitting punch 10, and the positioning block 14 is arranged between the guide plate I9 and the first through hole and used for positioning the workpiece at an angular direction.
As shown in fig. 8 to 10, a positioning elongated slot 91 for inserting the positioning block 14 is formed in one side surface of the first guide plate 9 along the height direction thereof.
As shown in fig. 8 to 10, two shaft seat plates 92 arranged at intervals are arranged at the upper part of the first guide plate 9, shaft holes 93 are arranged on the two shaft seat plates 92, and one end of the second guide plate 12 is inserted into a gap between the two shaft seat plates 92 and is hinged with the two shaft seat plates 92 through a third cylindrical pin 11.
The diameter of the press-fitting punch 10 is larger than that of the support punch 1.
The improved riveting tool changes a fixed positioning pin into a springing positioning pin to ensure the positioning accuracy, and the riveting is required to be more than 0.5mm in depth, so that the contact of the lower bottom surface of a phi 20 positioning hole on a support plate 3 must be cancelled, the final design scheme is that the positioning hole, a bearing outer ring and a support punch 1 are used for positioning, the phi 20 positioning hole limits the X-axis movement, the Y-axis movement, the X-axis rotation and the Y-axis rotation, a positioning block 14 in contact with the bearing outer ring limits the Z-axis rotation, the support punch 1 limits the Z-axis movement, the limiting is completed by the lower bottom surface of the phi 20 positioning hole, and the riveting is completed after the lower bottom surface of the phi 20 positioning hole is in contact with a phi 20 spring positioning pin 2 step surface, so that six-point positioning is realized, all the riveting requirements are met, double-sided positioning is realized, and the phenomenon of riveting offset and the shaft crossing problem are avoided due to accurate positioning.
Before riveting, the small hole (the hole of a press-mounting shaft and a bearing) of the rocker arm to be riveted is pressed into the bearing and the shaft and then riveted, the large hole (phi 20 hole) of the rocker arm to be riveted penetrates into the spring positioning pin 2 for centering during riveting, so that X-axis movement, Y-axis movement, X-axis rotation and Y-axis rotation are limited, then the outer ring of the bearing pressed into before is contacted with the positioning block 14 to be positioned and fixed to limit Z-axis rotation, the punch 1 is supported for positioning to limit Z-axis movement, and when the punch is pressed down, the lower bottom surface of the rocker arm is contacted with the step surface of the spring positioning pin 2 of the phi 20 to complete the riveting.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
