Definitions

  • the invention relates to a device for surface treatment, in particular for cleaning, polishing and grinding, consisting of a housing, optionally with a handle arranged thereon, an electric motor at least partially enclosed by the housing and running unbalanced by a flywheel, the end of which is towards the flywheel weight via a tool holder is firmly connected to a tool, and the unit consisting of motor and tool carrier is pendulum-like at the end of the motor opposite the flywheel weight by means of a pivotable holder arranged in the housing or on the handle, and in the area of the flywheel weight by a pivot pin arranged between tool carrier and housing or the like.
  • Existing oscillating bearing is held on the housing so as to be oscillatable and thus transmits an essentially circular oscillating oscillating movement to an object to be treated.
  • the much lower weight of the device disadvantageously causes the person operating the device to an excessively high working pressure, in the opinion that this can improve the treatment result.
  • this does not result in an overload of the motor due to the lack of a mechanical connection between the motor shaft and the tool holder, longer, longer pressure loads can lead to premature wear of the motor mounting, since the vibrations are then diverted to the housing.
  • the invention has for its object to eliminate this disadvantage in a device of the type mentioned.
  • this is achieved in that the motor and tool carrier are connected to one another by an additional elastic holder which acts more rigidly with respect to the elastic oscillating bearing.
  • a further oscillation system is thus formed within the existing oscillation system, which enables the drive motor to continue oscillating in the same way - namely in a circular oscillating oscillation movement - from a previously determinable pressure load.
  • the additional elastic holder consists of an oscillating element, preferably of a plurality of oscillating bolts known per se, since the desired elastic effect can be achieved more easily by such. Since these rocking bolts usually have molded nuts or grub screws, a connection between the motor and the tool holder is also easier to implement.
  • the oscillating bolts of the additional elastic holder and those for the oscillating bearing are of identical design and are evenly distributed in the plane perpendicular to the longitudinal axis of the motor, the oscillating bolts having a higher degree of hardness for the additional elastic holder and / or are arranged in larger numbers. This not only reduces the high tool costs, but also significantly simplifies the design of the device.
  • advantages according to the invention are also achieved if the motor is connected to the oscillating bolts of the additional elastic holder via a bracket surrounding the latter, which is designed as a joint ball at the end and a centering disk arranged on the drive-side motor end, the vzw.
  • Articulated ball is mounted in a one-piece bearing shell which is arranged in the housing end or in the handle and surrounds this at least half, the open side of which has a plurality of radial slots extending beyond the middle of the shell.
  • the electric motor 1 is driven unbalanced by the swing weight 2 and pivotally mounted in a pivot bearing 5 arranged at the end of the housing 4, so that this, together with the tool carrier 3 attached to it, transmits a circular oscillating swinging motion to an object to be treated.
  • the housing 4 consists of three parts, namely the load-bearing housing part 4, which runs conically towards the tool carrier 3 and the two shell-shaped parts 4 ', 4 ", which together form the bead-shaped handle.
  • the three housing parts are represented by means of several screws the lines of symmetry 7 - connected to one another
  • the housing part 4 ends with an annular shoulder
  • the shell-shaped tool carrier 3 is supported by three oscillating bolts 8 'which are evenly distributed on the outer housing edge and are arranged in the plane perpendicular to the longitudinal axis of the motor so that between the lower housing edge and the A gap of approximately 3 to 4 mm is created at the upper edge of the tool carrier 3.
  • the swing bolts 8 ′ formed on both sides with threaded pins 9 are screwed onto the tool carrier 3 at one end and connected to the housing 4 at the other end by means of the slotted nuts 10.
  • the motor 1 and the tool carrier 3 are connected to one another by an additional elastic holder 11 consisting of four swing bolts 11 '.
  • the swing bolts 11 ' are also arranged in the plane perpendicular to the longitudinal axis of the motor, evenly distributed around a center circle which is somewhat larger than the outside diameter of the motor.
  • the higher number of rocking pins 11 'used for the additional bracket 11 results in a higher stiffness compared to those of the rocking bearing 8.
  • the same may also have a higher degree of hardness.
  • the swing bolts 11 ' also have setscrews on both sides and are screwed onto the tool carrier 3 on one side and fastened to the motor 1 on the other side. This is done by means of a double-armed bracket 13 and a Zen arranged on the side of the swing weight 2 Trierarchitecture 14 enables which clamp the motor 1 after tightening the nuts 10.
  • the double-armed bracket 13 which is made of a pressed plastic part, ends with a ball head 15, which in turn is mounted in the one-piece bearing shell 16 so that it can be held and pivoted.
  • the bearing shell 16 comprises the ball head 15 more than half and is pressed over this. This is made possible by a plurality of radial slots 16 ′ arranged at the open end of the bearing shell 16 and extending approximately to the middle of the shell.
  • the bearing shell 16 arranged in an annular extension 19 in the housing part 4 ′′ is held by means of the screw 18.
  • the tool carrier consists of thin-walled plastic pressed parts. This is bowl-shaped and can fasteners on its circumference, for. B. record a ring 24 for a cleaning cloth 23. Other tools designed with different materials can e.g. B. be held by internal stress on this surface.
  • the underside of the tool carrier 3 can also be formed with a self-adhesive covering which holds various tools, such as skins, non-woven abrasives or sanding sheets, in a self-adhesive manner.
  • a switch 20 for switching the motor 1 on and off is arranged on the device, the power supply cable 22 being guided through the housing part 4 'via a rubber grommet 21.
  • the additional elastic bracket 11 can also consist of other vibration elements.
  • other designs of the vibration bearing 8 have no significant influence on the operation of the device.
  • the device according to the invention can be operated directly from the mains or via a mains transformer or also by rechargeable batteries. By attaching a handle, this can also be used as a floor device.
