Definitions

  • Cutting tool provided with measuring means
  • the current relates to a cutting tool provided with means and direct and continuous detection and / or detection of its wear and a tool holder for such a cutting tool.
  • It relates more particularly to a plate of sintered material (carbide, ceramic, etc.) and to its tool holder used for machining parts on machine tools.
  • Such a so-called “instrumented” cutting tool generally forms a one-piece assembly with its tool holder thereby resulting in a relatively high cost compared to a conventional tool consisting of an interchangeable removable insert and a tool holder.
  • the object of the invention is to provide an instrumented tool which is similar to conventional tools made up of two parts, thus making it possible to solve the problem of cost and also to offer the possibility of easily changing the cutting tool, in particular when the latter fails. or worn and possibly replace it with a conventional tool.
  • the subject of the present invention is a cutting tool, in particular a wafer made of sintered material, comprising a cutting edge and a probe or a micro-sensor inserted in the body of the tool near the cutting edge. section, characterized in that said probe or said micro-sensor of the tool is connected to a male contactor secured to the body of the insert capable of cooperating with a female contactor secured to a tool holder or vice versa.
  • the male contactor is partially embedded in the body of the tool.
  • the male contactor is housed in an insulating block which is integral with the underside of the tool.
  • said male contactor consists of at least one pin, preferably two pins ensuring the polarity for the transmission of the signal from the probe, advantageously made of a mixture of thermocouple material that protrudes from the underside of the tool.
  • the insertion of said pins into the tool is carried out either by laser drilling or by sintering in order to produce channels inside which the probe, the connection wires and the pins are arranged, and in this that an insulating resin ensures both the maintenance of the elements and their thermal and electrical insulation with respect to the tool.
  • said male contactor consists of two metal discs each housed in a recess formed on the underside of the tool.
  • said male contactor consists of two studs -or of balls- made of a mixture of Chromel and Alumel mounted on springs.
  • Another object of the present invention relates to a tool holder capable of receiving a cutting tool conforming to any one of the above-mentioned characteristics, characterized in that it is provided in a complementary manner to the contactors of the cutting tool.
  • the tool holder further comprises female contactors, sheathed wires ensuring connection to a second contactor housed in the tool holder in particular at its end opposite to the tool which is able to connect to a unit. analysis of information from the probe.
  • FIG. 1 is a top view of a cutting tool mounted on its tool holder according to the present invention
  • FIG. 2 is a sectional view along line l-l of FIG. 1,
  • FIG. 3 is a view on a larger scale of part A of FIG. 1, according to an alternative embodiment, and - Figures 4 to 6 are views in longitudinal section of three alternative embodiments according to the present invention.
  • a cutting tool 1 in particular a carbide insert of general triangular or polygonal section which is removably mounted on its tool holder 2 and held thereon, conventionally, by means a flange and a support wedge (not shown).
  • thermocouple type probe 3 is electrically isolated by means of, for example, a resin in the wafer 1 which also makes it possible to withstand the high temperatures reached during machining operations of the order of 800 to 1,400 ° C. .
  • the probe 3 or the micro-sensor of said removable insert is connected to a male / female contactor 4 secured to the body of the insert capable of cooperating with a female / male contactor 5 secured to the tool holder 2.
  • said male contactor 4 advantageously consists of at least one pin advantageously made of a mixture of chromel and alumel which projects from the underside of the plate 1.
  • thermocouple probe the male contactor consists of two pins 4, as visible in the figures
  • a counterplate 8 can be secured to the cutting tool
  • these pins 4 can be carried out either by laser drilling or sintering in order to produce channels 9 inside which there is the probe, the connection wires 6 and the pins 4. These equipped channels 9 are then filled with an insulating resin 7 ensuring both the maintenance of the elements 3 , 6 and 4 and their electrical insulation from plate 1.
  • the tool holder 2 is provided in a complementary manner to the contactors of the plate of female contactors 5 embedded in the body of the tool holder consisting of a housing made of a mixture of chromel and alumel and whose shape is capable of receiving by friction the shape of the pins of the male contactors 4 so as to transmit the continuity of the signal from the probe 3.
  • channels 10 are produced in the tool holder 2 in order to house the female contactors 5, as well as the sheathed wires 11 ensuring the connection to a second contactor 12 housed in the tool holder 2 which is able to connect to a unit for analyzing information from probe 3.
  • This second contactor 12 is fixed to the tool holder 2, for example at its free end opposite the cutting tool 1, by means of a screw 13 and held in a sealed manner in its housing 14 by a circular joint 15 .
  • the male contactors consist of studs or balls 17 made of thermocouple materials (example Chromel and Alumel) mounted on springs (not shown) thus ensuring by cooperation with a conjugated shape 18 mounted on the tool holder 2, as visible in FIG. 5, the continuity of the signal, said studs or balls being connected similarly to the first embodiment to a second connector 12.
  • the tool holder 2 is then provided with a housing 20 for receiving such a connection block 19.
  • this added block 19 can be located upstream or downstream of the wafer 1.
