Embodiment Construction

[0022] Identical, similar or analogous elements keep the same reference numerals in different figures.

[0023] figure 1 Shown is a detection system 10 for detecting a complete or partial blockage of at least one internal fluid conduit 11 of a tool 12, such as a machining tool. The one or more internal conduits 11 to be controlled can be used, for example, to supply the functional elements of the tool with a lubricating fluid, such as oil, an oily emulsion or a mist of air and oil. The system 10 may also be used to control a cryogenic processing tool 12 comprising at least one internal conduit 11 through which a cooling fluid, such as a nitrogen based cooling fluid, circulates.

[0024] Said system 10 is preferably used outside of machining operations carried out by the tool 12, that is to say the tool 12 is removed from the device to which it belongs for the first time, so that in said one or more internal pipes 11 Assembled on the system 10 at the end of the control. That...

Abstract

The invention primarily relates to a system (10) for detecting a total or partial obstruction of at least one internal fluid pipe (11) of a tool (12), characterised in that said system (10) comprises: a pneumatic system (13) that is intended to be connected upstream of said internal pipe (11) of said tool (12), a pressure source (16) that is connected to said pneumatic system (13) by means of a solenoid valve (17), and a control unit (22) that is configured to open said solenoid valve (17) so as to pressurise said pneumatic system (13), and then to close said solenoid valve (17) so as to let said pneumatic system (13) be emptied freely by means of said internal pipe (11), and to detect an obstruction state of said internal pipe (11) depending on an analysis over time of a change in the pressure in said pneumatic system (13).

Description

[0001] This application claims priority from French application 1550022 filed on January 5, 2015, the content of which (text, drawings and claims) is hereby incorporated by reference. technical field [0002] The invention relates to a detection system for detecting partial or complete blockage of an internal conduit of a tool. The invention finds a particularly advantageous, but not exclusive, application for controlling a processing tool having one or more internal conduits for providing the functional elements of the tool with Liquid or gaseous lubricating or cooling fluids such as oil, oil emulsion, mist of air and oil, or others. Background technique [0003] Document EP2320199 teaches a method of detection of particle clusters in pipelines by using a flow meter. The system determines sudden changes in flow and provides an alarm signal when the flow exceeds design limits. Similarly, document FR2851819 shows the use of an electrostatic flowmeter to measure the amount o...
