Detailed Description

The utility model is further described below with reference to the accompanying drawings: as shown in the figure, the anti-pull-out part riveting point tool for the three ball pins of the AAR joint comprises a base 1, wherein a sinking groove 2 is formed in the base, the circumferential inner wall of the sinking groove is matched with the circumferential outer wall of the bell-shaped shell 91 of the AAR joint, a plurality of tips 3 are arranged at the bottom of the sinking groove and are used for riveting holes on the axial end face of the bell-shaped shell 91 of the AAR joint. At least three surfaces of the circumferential inner wall of the sinking groove are matched with the outer wall of the bell-shaped shell, when the sinking groove is used, the AAR joint is placed on a tool as shown in fig. 5, then the AAR joint is pressed down in a hydraulic machine or other modes, the axial end face of the bell-shaped shell 91 of the AAR joint is contacted with the bottom end face of the sinking groove, the contact part of the product is deformed after the product is subjected to the pressure of the center, uniform sinking is generated, the sliding position of the tripod pin in the ball channel is limited, the tripod pin is prevented from falling out of the ball channel, and the occurrence of riveting leakage or riveting error is prevented.

In this embodiment, as shown, the base includes an upper die 11 and a lower die 12 that are detachably connected. Is convenient to disassemble and assemble.

In this embodiment, as shown in the drawing, the upper die and the lower die are connected by screws. The screw passes through the upper die and is connected with the lower die, and the disassembly and the assembly are convenient.

In this embodiment, as shown in the drawing, the lower die is provided with a plurality of detachably connected gaskets 4, the gaskets are provided with first through holes 41 for the tips to pass through, and a plurality of gaskets are stacked on each other for adjusting the lengths of the extended tips. The gaskets with different numbers are used for realizing the exposure of different tip lengths so as to adapt to different use requirements, through holes for the tips to pass through are formed in the gaskets, and meanwhile, the gaskets are limited.

In this embodiment, as shown, the spacer is further provided with a second through hole 42 for the screw to pass through. The screw passes through the second through hole and has a certain limiting effect on the gasket.
