Embodiment 1

[0028] Such as figure 1 As shown, a joint bearing assembly guide positioning riveting device includes a guide seat 2 and a guide mandrel 1 and a riveting head 7; the guide seat 2 includes an upper guide 3 and a lower guide 4 that are connected as a whole. A certain riveting space is formed between the guide 3 and the lower guide 4, and the riveting head 7 and the joint bearing 10 are arranged in the riveting space. The guide mandrel 1 includes a guide rod 5 and a guide positioning column 6 that can be connected to the guide rod 5 as a whole. The upper guide 3 is provided with a guide hole that matches the guide rod 5, and the lower guide 4 A positioning hole 9 coaxial with the guide hole 8 and matched with the lower end of the guide positioning column 6 is provided. The guide rod 5 is provided with a connecting hole at one end close to the riveting head 7, and the upper end of the guide positioning pillar 6 penetrates the riveting head 7 and is inserted into the connecting hole...

Embodiment 2

[0031] Such as figure 2 As shown, on the basis of the above-mentioned embodiment, this embodiment has been improved. The improvement is that a locking sleeve 13 is provided at the connection between the guide rod 5 and the guide positioning column 6 for the guide rod 5 and the guide The positioning column 6 is locked during the riveting process of the joint bearing 10 so that the guide rod 5 and the guiding positioning column 6 are closely attached. The connecting end of the guiding and positioning column 6 and the guiding rod 5 is a tapered end surface, and the bottom surface of the connecting hole 14 is matched with the guiding and positioning column 6 to be tapered to enhance the adhesion between the guiding and positioning column 6 and the guiding rod 5. Between the guide rod 5 and the riveting head 7 is a pressure cap 15 that is coaxially installed with the guide mandrel 1, and the center of the pressure cap 15 is provided with a through hole through which the guide mandr...

Abstract

The invention discloses a guiding-positioning riveting device for assembly of a joint bearing. The guiding-positioning riveting device comprises a guide seat, a guiding core shaft and riveting heads. The guide seat comprises an upper guide part and a lower guide part which are connected into a whole; a certain riveting space is formed between the upper guide part and the lower guide part; the riveting heads and the joint bearing are arranged in the riveting space; the guiding core shaft comprises a guiding rod and a guiding-positioning column, wherein the guiding-positioning column is arranged below the guiding rod, and the guiding-positioning column and the guiding rod are matched into a whole; and the guiding core shaft penetrates through the upper guide part, riveting heads and the bearing joint from top to bottom to be connected with the lower guide part. In working, the guide seat provides the effects of guiding and supporting, the guiding-positioning column and the guiding rod provide the effects of positioning and pressure transmitting, the riveting load acts on the riveting heads through a pressing cap, assembly and fastening of the self-lubricating joint bearing are completed, and the problems of stable transmission, deviation of the guiding core shaft and the positioning failure during assembly and installation and the like in the riveting process are solved.

Description

Technical field [0001] The invention relates to the field of joint bearing installation, in particular to a joint bearing assembly guide positioning riveting device and an assembly method. Background technique [0002] Joint bearings are also called spherical sliding bearings, and their structure consists of an outer ring with a spherical surface and an inner ring with an outer spherical surface. Self-lubricating joint bearing is a special spherical plain bearing with PTFE composite liner film. When assembling parts, press the outer surface of the annular groove on the upper and lower end faces of the outer ring of the bearing through the mold, so that the outer side of the pressed groove is squeezed and flanged and the metal is plastically deformed, so that the flanging tightly wraps the assembly bottom hole In order to achieve the purpose of firm bearing assembly, the flanging fastening operation process is called the riveting fastening process. [0003] The starting torque of ...
