Definitions

  • the present invention relates to a kit of telescopic arms for in-depth vertical machining.
  • Known telescopic arms consist of two or more tubular units, extractable and retractable the one with respect to the other.
  • Known arms are associated with the respective operating machine by means of specific attachment means arranged in the proximity of the machine and in the proximity of the arm.
  • such attachment means provide for the hinging of the arm to the machine by means of suitable hinge pins, so as to allow the telescopic arm to rotate around the axis of the pins themselves assuming different positions.

  • machines of different mass and power and arms of different size and weight are used.
  • the machine used in turn must have a mass sufficient to counter-balance the weight of the arm and of the tool.
  • a drawback of prior art is that the machines on the market used for vertical machining are adapted to support a single telescopic arm specifically designed for the machine itself.
  • the arm in question has dimensions and weight within certain values compatible with the machine itself. This implies that the user, in case of having to work with arms of different length, must have several machines, with a consequent increase in overall dimensions, transport costs and costs associated with the machines themselves. In the case where the end user does not intend purchasing or finds it too costly to purchase several machines, he/she has the chance to rent them from special rental companies.
  • end users and rental companies may disassemble the arm of a machine and assemble it on another.
  • the main aim of the present invention is to provide a kit of telescopic arms for in-depth vertical machining that allows to assemble and disassemble easily and fast different types of telescopic arms on one or more machines.
