Embodiment Construction

[0035] It should, of course, be understood that the description and drawings herein are illustrative only, and that various modifications and changes can be made in the disclosed structures without departing from the disclosure. In general, the drawings of the exemplary work tool and removable work head are not necessarily to scale. It should also be understood that the various identified components of the exemplary work tool and removable work head disclosed herein are terms of the art that may vary from manufacturer to manufacturer and are not to be considered limiting of the present disclosure.

[0036] The present disclosure relates generally to hydraulic tools, and more particularly to selectively attachable work heads and quick release couplings for such tools. In certain versions of the disclosure described in greater detail herein, the work tool is in the form of a hand-held hydraulic work tool. Typically, a work tool includes a hydraulic cylinder or body, a ram ram a...

Abstract

A hand-held hydraulic assembly includes a work tool having a hydraulic cylinder or main body, a ram piston disposed in the hydraulic main body and a spring or other biasing member mounted on the ram piston. An interchangeable work head is selectively engaged to the ram piston of the work tool. The ram piston is axially displaceable in the main body for actuating the work head. A quick release coupling mounted to the work tool releasably connects the interchangeable work head to the work tool.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 827,842, filed May 28, 2013. technical field [0003] This topic deals with hydraulic tools and interchangeable work heads. More particularly, the subject matter relates to interchangeable and detachable work heads for use with work tools such as hand-held hydraulic crimping, cutting, punching or pressing devices. Background technique [0004] Hydraulic work tools are used in many applications to provide a desired mechanical advantage to a user. One example is in crimping tools used to make crimped connections, such as crimping terminals onto conductors. Another example is in cutting tools where the tool allows the user to apply a relatively large amount of force or pressure. In order to implement these various applications with one work tool, a detachable work head system is desired. Using the same work tool with different removable / interchangea...
