Detailed Description
In order to facilitate the understanding of the technical solutions of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the drawings attached to the specification.
As shown in fig. 1 to 3, the utility model provides a riveting internal stay mechanism, be trapezoidal centre voussoir 7 including a cross section, the two inclined planes outsides of centre voussoir 7 are provided with the bloated tight piece of first bloated tight piece 2 and the bloated tight piece 8 of second respectively. And the first expansion block 2 and the second expansion block 8 are respectively provided with a limiting shoulder 13. The wider bottom surface of the middle wedge block 7 is connected with a driving mechanism 6, and the driving mechanism 6 drives the middle wedge block 7 to move relative to the first expansion block 2 and the second expansion block 8.
Based on the above technical solution, when the joint yoke portion 10 of the intermediate shaft yoke 1 is subjected to the cross bearing butt riveting, the whole intermediate shaft yoke 1 is fixed by an external fixing device. Then stretch into first bloated tight piece 2 and the bloated tight piece 8 of second and arrange in the festival fork portion 10 of jackshaft festival fork 1 again, first bloated tight piece 2 and the bloated tight piece 8 of second are prevented under the effect of respective spacing shoulder 13, can not continue to move forward, and at this moment, actuating mechanism 6 drives middle voussoir 7 and continues to move between the tight piece 8 of first bloated tight piece 2 and the bloated tight piece 8 of second, realizes the bloated tight of outside to tight piece 2 of first bloated tight piece and the bloated tight piece 8 of second. Namely, the first expansion block 2 and the second expansion block 8 expand the joint fork part 10 of the intermediate shaft joint fork 1 outwards. After the joint fork part 10 of the intermediate shaft joint fork 1 expands, the cross bearing 9 is placed in the joint fork part 10, and the cross bearing is riveted. After the operation is finished, firstly the middle wedge block 7 retracts under the action of the driving mechanism 6, the first expansion block 2 and the second expansion block 8 are loosened after the middle wedge block 7 retracts, then the first expansion block 2 and the second expansion block 8 are separated from the joint fork part 10 of the middle shaft joint fork 1, and the cross bearing butt riveting operation of the whole middle shaft joint fork 1 is finished.
As shown in fig. 1 to 3, the two limiting shoulders 13 of the present invention are provided with a connecting mechanism 4 on the end surface close to the driving mechanism 6, and the connecting mechanism 4 and the middle wedge 7 are connected near to the driving mechanism 6. The connecting mechanism 4 realizes synchronous movement of the first expansion block 2 and the second expansion block 8 and the middle wedge 7, and when the driving mechanism 6 drives the middle wedge 7 to move, the first expansion block 2 and the second expansion block 8 move together into the joint fork part 10 along with the middle wedge 7 in the first stage (the limit shoulder 13 is not stopped by the joint fork part 10 yet). When the driving mechanism 6 drives the middle wedge block 7 to retract, the first expansion block 2 and the second expansion block 8 are separated from the joint fork part 10 along with the middle wedge block 7.
As shown in fig. 1 to 3, the connecting mechanism 4 of the present invention includes a coil spring, and the axis of the coil spring is parallel to the moving direction of the middle wedge 7. Adopt coil spring, can be when actuating mechanism 6 drives middle voussoir 7 and retract, first bloated tight piece 2 and the bloated tight piece 8 of second reset along with middle voussoir 7 simultaneously. The integral structure of the riveting internal support mechanism is effectively simplified, the size of the riveting internal support mechanism is reduced, the riveting internal support mechanism is convenient to adapt to use at various positions, and the cost can be reduced.
As shown in fig. 1 to 3, the side of the first expanding block 2 and the second expanding block 8 away from the middle wedge 7 in the technical solution of the present invention is adapted to the inner side of the joint fork 10 of the middle shaft joint fork 1. And the opposite side surfaces of the first expansion block 2 and the second expansion block 8 are respectively parallel to the inclined surfaces of the middle inclined blocks 7. First bloated tight piece 2 and the tight piece 8 of second and the face of festival fork portion 10 medial surface contact suit with festival fork portion 10 medial surface, when the bearing is adorned on two sides of festival fork portion 10, the pressure transmission of external assembly to festival fork portion 10 is on first bloated tight piece 2 and the tight piece 8 of second bloated, and because first bloated tight piece 2 and the tight piece 8 of second bloated is under the effect of trapezoidal middle voussoir 7 at spring and cross section, certain displacement that floats has, so, festival fork portion 10 can not receive the extrusion damage. First bloated tight piece 2, the second bloated tight piece 8 and the inclined plane slope of voussoir 7 is less, generally sets up at 3 ~ 10 for when first bloated tight piece 2 and the second bloated tight piece 8 receive the extrusion, this riveting internal stay mechanism has certain auto-lock ability, and first bloated tight piece 2, the second bloated tight piece 8 can not give way when receiving pressure, has guaranteed that the festival fork can not warp when receiving pressure. The riveting internal bracing mechanism is suitable for hollow parts, two sides of the hollow parts need to be stressed, and the product has insufficient strength, such as the intermediate shaft yoke 1.
As shown in fig. 1 to 3, the middle wedge 7 of the present invention is connected to a connecting block 5 through a connecting pin 11 on the bottom surface of the wide width, and a driving mechanism 6 is connected to the connecting block 5. The drive mechanism 6 includes a cylinder or an oil cylinder.
As shown in fig. 1 to fig. 3, the utility model discloses technical scheme a riveting internal stay mechanism adopts first bloated tight piece 2, the bloated tight piece 8 of second and middle voussoir 7 two relative inclined planes symmetry to expand, the interior dimensional error of fine adaptation product.
The technical solution of the present invention is to provide an improved method for manufacturing a semiconductor device, which is characterized in that the method is not limited by the above-mentioned method, and the method is not substantially improved by the method and the device, or the method and the device are directly applied to other occasions without improvement, all within the protection scope of the present invention.
