Reducing roll riveting mounting tool for knuckle bearing

Abstract

The invention discloses a reducing roll riveting installation tool for a knuckle bearing, which comprises a connecting screw handle, one end of the connecting screw handle is fixedly connected with one end of a supporting disc body, the other end face of the supporting disc body is provided with three soil-shaped groove structures evenly distributed along the axis, and each soil-shaped groove is correspondingly provided with a moving body. A roller support is fixedly installed on the upper side of each moving body, a roller assembly is arranged at the upper end of each roller support, a mandrel assembly is arranged on the central axis of the other end face of the supporting disc body, the mandrel assembly is clamped and positioned through the end faces of the three moving bodies at the same time, and the mandrel assembly comprises a positioning mandrel and a lubricating sleeve; the knuckle bearing variable-diameter roll riveting installation tool is matched with different core shaft assemblies according to knuckle bearings of different models and sizes. The roll riveting installation tool adapts to roll riveting work of bearings of different specifications and models by replacing the positioning mandrel to change the position of the rolling wheel, the tool utilization rate is increased, the economic cost is reduced, and the universality is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a variable-diameter rolling riveting installation tool for joint bearings. Background technique [0002] Joint bearings, also known as spherical plain bearings, are widely used in aerospace, engineering machinery, water conservancy and hydropower and other fields. The installation and fixation of the spherical plain bearing directly affects its service life. If the spherical plain bearing is not properly installed and fixed, the phenomenon of locking the outer ring of the inner riveting head of the bearing is likely to occur. Therefore, it is of great significance to study the installation process of the spherical plain bearing. The rolling riveting installation process of joint bearings has irreplaceable advantages over the currently used pressure riveting and spin riveting processes, mainly including: small loading force of equipment, small harmful deformation ...

AI Technical Summary

Problems solved by technology

At the same time, each type of spherical plain bearing requires a corresponding single type of rolling riveting tool for installation, but the production and processing costs of a single type of rolling riveting tool are relatively high, and the types of spherical plain bearings that need rolling riveting installation are various and have different standards. , each country and each manufacturer develops its own standard bearing models, resulting in the high cost of designing and processing separate rolling riveting installation tools for each type of bearing
