Definitions

  • the present invention relates to a mortising tool for slotting machines, particularly for laminated wood beams and the like. More particularly, the invention relates to a mortising tool for forming slots or so-called mortises in laminated wood beams or in other materials in which slots must be formed.
  • laminated wood describes the superimposing and gluing of a plurality of layers of wood in order to form elements having the intended cross-section to be used, for example, as load-bearing beams for building structures and the like.
  • Said beams usually have a considerable cross-section and must be connected to each other for construction purposes.
  • inserts generally constituted by metal plates which are placed in slots or mortises formed in the surface of the beam, so that one half of the insert is thus inserted into the slot of one beam and the other half is inserted in the slot of the beam to be connected to the first one.
  • the plates are then bolted to the beams, thus providing a stable coupling.
  • Suitable machines are used to form the slots; they are attached to the beam to be machined and have a tool which consists of a guiding plate around the perimeter whereof a slot milling chain is provided which can move, close to the guiding plate that supports it, in a preset direction of rotation.
  • the guide provided with the chain is constituted by an elongated flat body in which one end or head is meant to bite into the wood of the beam in order to form the slot and the chain has, for this purpose, teeth to remove the wood.
  • Said tools are used successfully to form slots whose width is equal to the width of the guide and thus to the size of the head.
  • the friction encountered by the head of the guiding plate is such that it is overcome by the force of the motor that turns the chain and therefore milling performed with the head is easy.
  • the aim of the present invention is to provide a mortising tool for slotting machines, particularly for laminated wood beams, which is capable of forming a slot of chosen width in a beam without having to extract and reinsert the tool, head first, in the beam in which the slot must be formed.
  • an object of the present invention is to provide a mortising tool for slotting machines, particularly for beams made of laminated wood or other materials, which is capable of cutting both with its head and with at least one long side of the guiding plate.
  • Another object of the present invention is to provide a mortising tool for slotting machines, particularly for laminated wood beams, which can work with both sides of the guide as well as with the head of said guide.
  • Another object of the present invention is to provide a mortising tool which is highly reliable, relatively easy to manufacture, and at low costs.
  • a mortising tool for slotting machines which comprises a guide which is meant to form a mortise in association with a slotting machine and is constituted by an elongated body which has a shaped head, said guide supporting, along its perimeter, a slot milling chain which can move in a given direction of rotation around said guide, characterized in that said slot milling chain is supported by antifriction means which are arranged along the head and at least one long side of said guide, in order to allow easier sliding of said milling chain and both head and side milling with said chain.
  • the mortising tool according to the invention comprises a guiding plate or guide 1, constituted by a flat elongated body which is substantially trapezoidal; a slot milling chain 2 is arranged around its perimeter and rotationally slides around the guide 1 and in contact therewith.
  • the milling chain 2 is formed, in a conventional manner, by links provided with teeth 4 which are meant to mill the beam or element in which the slot must be formed.
  • the teeth 4 are arranged so as to protrude from the lateral surface of the guide 1 and are staggered along the extension of the guide 1.
  • the guide 1 supports a plurality of antifriction means, advantageously provided by bearings 3 which assist the sliding of the slot milling chain 2 along the guide 1.
  • the bearings 3 are arranged so as to lie flat on the guide 1 and protrude slightly from the edge of said guide, so as to support the milling chain 2 and thus prevent its contact with the edge and therefore prevent it from jamming due to the considerable friction that is generated.
  • Figure 2 illustrates in detail, in a sectional view, a bearing 3 which supports the chain 2.
  • the reference numeral 5 designates one of the pivots that form each link of the chain 1
  • the reference numeral 6 designates covering plates accommodated in recesses 8 formed by the guide at the end of through holes which accommodate the bearings 3; screws 7 are also provided for locking the plates 6 and for centering the bearings.
  • the chain 2 thus protrudes from the covering plate 6.
  • the tool 100 is suitable to be connected to a slotting machine (not shown), in which a motor drives the chain 2 rotationally along the perimetric extension of the guide 1.
  • the bearings 3 are advantageously closely spaced along the cutting side and the head of the guide 1, while on the opposite side of the guide, not affected by cutting, a single bearing is provided.
  • two bearings 4 are provided which are arranged at the corners of said head because the centrifugal force generated by the rotation of the slot milling chain 2 is greater proximate to the head and therefore the chain would tend to separate from the edge of the guide 1.
  • the tool according to the invention fully achieves the intended aim and objects, since it allows to provide slots or mortises without having to continuously insert and remove the blade of the tool.
  • the materials employed may be any according to requirements.
