Description

Technical Field

[0001] The utility model relates to the field of elastic cylindrical pin assembly, and more specifically, to an elastic cylindrical pin assembly tooling. Background Art

[0002] An elastic cylindrical pin is a commonly used connecting part in mechanical part assembly. A common connecting structure is that the elastic cylindrical pin passes through the mounting holes on two parts and achieves an interference fit in one or more of the mounting holes. Since the outer diameter of the elastic cylindrical pin is larger than the aperture of the mounting hole, a certain pressure needs to be applied to the elastic cylindrical pin to install it. During manual assembly, generally one hand is used to hold the elastic cylindrical pin upright so that the elastic cylindrical pin is perpendicular to the mounting hole, and then a hammer is used in one hand to strike the elastic cylindrical pin to make it pass through multiple mounting holes.

This elastic cylindrical pin assembly tooling makes the mounting holes of each part coaxial through the ejector pin in the auxiliary mechanism, so that the elastic cylindrical pin is vertically installed into each mounting hole, solving the problems in the prior art that the assembly between each part and the elastic cylindrical pin is manually realized, resulting in low assembly efficiency, high product rejection rate, and the risk of work injury due to operation errors; this elastic cylindrical pin assembly tooling positions the elastic cylindrical pin through the ejector pin. At the same time, during the installation process, the ejector pin is driven by a spring to completely retract downward, so that the elastic cylindrical pin is installed into the mounting hole. The elastic cylindrical pin is placed into the second through hole through a knocking rod, and then it can be more easily vertically placed into the mounting holes of each part and is convenient for operation.
