Integrated tightening and riveting mechanism for steering gear adjusting nut and application method thereof

Abstract

The invention discloses an integrated screwing and riveting mechanism for a steering engine adjusting nut and an application method of the integrated screwing and riveting mechanism. The integrated screwing and riveting mechanism comprises the adjusting nut. The adjusting nut is arranged in a set machine tool limiting position where in the adjusting nut is screwed into a shell. An integrated screwing and riveting mechanism assembly is arranged on the adjusting nut. The screwing axis and the riveting pressure axis of the assembly coincide in the same axis. The integrated screwing and riveting mechanism assembly can move up and down. After the adjusting nut arranged under the assembly and the shell are screwed, the adjusting nut is subjected to riveting pressure through the integrated screwing and riveting mechanism assembly. The screwing and riveting mechanism is optimized into an integrated structure, compared with traditional two mechanisms and two processes of screwing and riveting, a set of sliding table air cylinder is omitted, due to the fact that the mechanism is compact, the station beat can be shortened by 6 S, and the production efficiency is greatly improved; and the integrated screwing and riveting mechanism is free of secondary positioning, so that the riveting point position is not liable to go away during riveting, and the finished production quality is greatly improved.

Description

technical field [0001] The invention relates to a part assembling device, in particular to an integrated tightening and riveting mechanism used for assembling an adjusting nut of a steering gear in the field of automobile parts manufacturing. Background technique [0002] At present, various automobile steering gear assemblies need to be riveted after the adjustment nut is tightened to the specified torque when the pressure block, spring and adjustment nut are installed in the steering gear. [0003] The conventional riveting mechanism and tightening mechanism for adjusting nuts in the prior art are two separate mechanisms. The process is as follows: [0004] After the steering gear is fixed in front of the machine tool, the electric tightening gun descends to tighten the adjustment nut into the steering gear, and then the electric tightening gun rises back to its original position. The booster cylinder is lowered with the riveting head to carry out the riveting pressure o...

Problems solved by technology

[0005] After a long time of operation and feedback by the workers on site, it was found that the existing technology has a relatively long working cycle in the whole process of mechanism operation, and the manufacturing speed is slow, and because the two steps of the two mechanisms need to position the adjustment nuts separately, it often leads to riveting. The problem of the deviation of the center of the riveting point
