Definitions

  • the present invention relates to a manual electrical tool such as for example a honing or lapping machine, with a motor and dust suction means incorporated in the handle.
  • This arrangement has the merit of offering better handling of the tool since the motor is held in the user's hand and thus affords effective balancing of weights.
  • the object of the present invention is to obviate said shortcomings by making a manual electrical tool of the type having a motor housed in the handle and having improved means of evacuation of the dust produced by the work.
  • a manual electrical tool of the type comprising a work head, a handle extending radially from said work head, and a motor housed in said handle characterized in that it also includes a fan to suck in the dust generated by the work and convey it into a discharge duct for sucked dust, said fan being placed on the output shaft of the motor at the end of the handle turned toward the work head.
  • the dust discharge duct is incorporated in the handle beside said motor.
  • the orbital honing machine illustrated therein is structurally formed of a work head 10 from which extends a radial handle 12 made in an overturned-U boxed form as shown in FIG. 3.
  • the upper part of the handle 12 is divided by an intermediate baffle 31 into a front space 32 and a rear space 33.
  • an electric motor 13 on the output shaft of which are keyed two integral fans 17, 18 the first of which is designed to cool the motor 13 and the second of which is designed to suck the dust produced by the honing operation following the path indicated by the arrows in FIG. 1.
  • said fans 17 and 18 can also be separated.
  • a discharge duct 26 for the dust produced during work the cross section area of which is small beneath the motor 13 and larger beneath the rear space 33 of said handle (FIGS. 2 and 3) where the duct 26 acts as a bottom closing element for said handle.
  • the handle 12 can be closed below by an intermediate baffle and the duct 26 is in this case simply affixed thereto.
  • the handle can also have a configuration different from the essentially straight one shown only as a nonlimiting example.
  • the duct 26 terminates with a saw-toothed connection 28 for a flexible exhaust tube to convey the exhausted dust into a collecting container.
  • a dust collection bag of flexible material To the connection 28 there can also be directly applied a dust collection bag of flexible material.
  • the work head 10 comprises an external body 11 within which is housed in the conventional manner a mechanism for transmission of the motion of the shaft 15 of the motor 13 to a plate 22 having suction holes 20 and on which can be applied a sheet of abrasive paper (not shown). More specifically the plate 22 is fixed to a shaft 23 born in a turning manner by an excentric hub 24 fixed to a shaft 21 made to rotate by the shaft 15 of the motor 13 through a pair of gears 34 and 35.
  • the honing dust is sucked in by the fan 18 through the holes 20 in the plate 22 and fed into the discharge duct 26. Then the dust is discharged outside the tool.
