Definitions

  • the invention is based on a hand vibration grinding machine according to the preamble of claim 1.
  • This hand-held vibratory grinding machine has a much better Efficiency than that with elastic vibrating elements, they but has a higher weight and is more expensive to produce as the known machines with elastic Oscillating elements.
  • the hand tool of the invention with the Features of claim 1 has the advantage over equally good efficiency, smooth running with less Weight and lower production costs than the known machines.
  • the elastic oscillating elements on opposite Ends will carry a circumferential constriction, respectively thus created a 360 ° effective film hinge
  • the oscillation property of the oscillating elements is improved in such a way that they only use very small amounts of energy Drive motor absorb, the efficiency of the machines and their life is significantly increased.
  • the vibrating elements are easy to manufacture and easy to assemble ,.
  • the film hinges are transverse to the radial Recesses flexurally soft or more elastic than parallel to the recesses or in the direction of the elongated web.
  • the invention is based on an associated Drawing described in more detail.
  • the hand-held vibratory grinding machine 10 shown in FIG. 1 has a elongated, serving as a handle machine housing 12, which receives an electric motor 13.
  • the machine housing 12 carries a sliding button 14 above to turn on and off the Engine 13.
  • a sanding plate 18 is arranged on the machine housing 12 for releasably receiving a sanding sheet 19.
  • a flexible shaft 101 transmitted.
  • the flexible shaft with its first end above and immediately adjacent to the eccentric pin 120 in one lower rolling bearing 140 rotatably mounted on the machine housing 12.
  • the motor side the flexible shaft 101 via a Plug-in coupling 150 with an unspecified motor shaft coupled. It is also near the plug-in coupling 150, the flexible shaft 101 in an upper roller bearing 160 in Machine housing 12 rotatably mounted.
  • the sanding pad 18 is about leaf spring-like vibrating elements 170, 180 on the machine housing 12 against losing and secured against rotation secured. Between the Sanding plate 18 and the machine housing 12 is as elastic Connecting element arranged a bellows 12 through despite the swinging movement of the sanding pad 18 below can dissipate dust.
  • the oscillating elements 170, 180 carry at their upper and lower End ever a constriction or waist 50, 52, through which the elastic rods each like a propshaft function. This minimizes the loss of power because the damping of the sanding disc vibration to the necessary Dimension is reduced. In addition, the smoothness of the Grinding hand tool significantly improved.
  • FIGS 3 and 4 show the rear and front elastic Oscillating element 170, 180, consisting of an upper and lower Transverse page 55, 57 consists, between each three extend columnar single elements. Near the cross leaves 55, 57 every single swinging column has a sidecut 50, 52.
  • the arranged at the top of the grinding plate 18, in FIG 4 shown vibrating element 180 consists of the transverse leaves 59, 60, between which are four individual wings with sidepieces 50, 51 extend.
  • the efficiency of the Oscillating element 180 is through the sidecut 50, 52 on the the same way as the vibrating element 170 according to FIG. 3.
  • circumferential constrictions or waistlines two each concave, semi-cylindrical recesses transverse to the vibrating elements facing away from each other at the same place.
  • a film hinge is formed, which is transverse to the axis the recesses very flexible and parallel to the axis of the Recesses significantly more rigid deformable. This is when using such vibrating elements approximately the Vibration behavior of a linear grinder achievable.
