  • the holder 3 of the turning tool 1 has a tubular member 15 that covers the cable 11 and is fitted in the hole 13c.
  • the gap between the cable 11 and the hole 13c is reduced, the airtightness of the hole 13c is improved. As a result, for example, the probability that dust and / or liquid will enter the hole 13c is reduced.
  • the inside of the first member 7 is also protected from dust and / or liquid.
  • the liquid include a cutting agent (for example, oil) supplied for cooling and / or reducing friction during turning.
  • the Young's modulus of the tubular member 15 is smaller than the Young's modulus of the second member 13.
  • the adhesion between the tubular member 15 and the second member 13 can be improved, and the above-mentioned dustproof and / or waterproof effect can be improved.
  • the strength of the holder 3 of the turning tool 1 can be improved as compared with a mode in which the Young's modulus of the second member 13 is relatively small (this mode is also included in the technique according to the present disclosure).
  • the Young's modulus of the tubular member 15 is small, the force locally applied from the tubular member 15 to the cable 11 is relaxed. This protects the cable 11. This effect is improved when the tubular member 15 protrudes from the holding hole 13ca and can be flexed and deformed, and / or when the tubular member 15 is made of an elastic body.
  • the turning tool is not limited to the insert type tool in which the insert (a type of tip) is detachably attached to the holder (turning tool body).
  • the turning tool may be a welding tool in which the tip is welded to the turning tool body or a brazing tool in which the tip is brazed to the turning tool body, or a blade portion is formed by a part of the turning tool body. It may be a welding tool (also called a solid tool).
  • the turning tool main body (more specifically, the first member) may be configured separately from the blade portion. However, it may be integrally configured with the blade portion (or include the blade portion). That is, in the present disclosure, when the first member "holds the blade portion", any of the above aspects is included.
  • the usage of such terms is the same as the usage of the term of body (which can be the main body when translated into Japanese) in the technical field of cutting tools.
  • the term body is sometimes used to refer to a narrow range of the part that holds the blade of the cutting tool, excluding the shank.
  • the turning tool body is not used as a term to refer to such a narrow range, as is clear from the definition including the cable and the like.
  • the blade when the blade is attached to the holder, the blade is not limited to the one composed of chips (inserts, etc.).
  • a peeling tool may be attached to the holder, such as a plug-in tool.
  • the turning tool may be configured as an adjusting tool whose external dimensions and the like can be adjusted.
  • one end of the cable is located in the first member.
  • the cable may not be directly connected to the sensor, but may be connected to the sensor, for example, via a metal piece extending from the first member to the second member.

Abstract

La présente invention concerne un porte-outil de tournage comprenant un premier élément, un second élément, un capteur et un câble. Le premier élément contient une partie lame. Le second élément est accouplé au premier élément. Le capteur est placé à l'intérieur du premier élément. Le câble est relié au capteur et s'étend hors du second élément. Le second élément peut tourner autour d'un axe de coulissement prescrit par rapport au premier élément. Le câble s'étend hors du second élément dans une direction croisant l'axe de coulissement.
