Articulating support for construction machine constituting a quick release fastener and related manufacturing method

A method of manufacturing an articulating support device that includes, in an upper part, two lines of axles associated with the tool arm of a public works machine, with the lower part of this support being removably attached to a tool, the method including:

• manufacturing a one-piece unit of a generic articulation support, equipped with two opposing lateral flanges, each with a sufficiently large area to allow creation of connecting orifices that are proper to each works machine and variable to suit the class of machines;
• a first specialisation step performed on the generic support and that includes re-machining an upper part in order to form, on each flange, a new top edge that allows collision-free movement of the support device around the arm on the connecting axle to the works machine;
• a second specialisation step including drilling, in the support emerging from the first specialisation step, two pairs of orifices divided between the lateral flanges above the top edges, and whose positioning in terms of angle and coordinates on the flanges depends on the kinematic of the machine for which the device is intended;
• a third specialisation step including machining the lower part of the support emerging from the second specialisation step, of a connection means;
• a fourth specialisation step including fitting, to the support obtained from the third specialisation step, through the respective pairs of orifices, of two cylindrical members of the same predetermined length, by using adaptation bearings, and locking means, in translation and/or rotation, of the cylindrical members.
