Definitions

  • the invention relates to a hand-held machine tool with a rotatably drivable by a drive motor tool holder for a machining side for abrasive and / or cutting Werkêtbearbeitung exhibiting tool with a tool space for receiving the tool having cover for at least partially covering the tool according to the preamble of the claim 1.
  • the idea according to the invention is that the flow cross-section is smaller at a greater distance from the inlet opening of the dust discharge connection. As a result, an optimum suction effect is also achieved there, if advantageously e.g. a vacuum cleaner is connected to the dust discharge port.
  • the dust removal, in particular a suction so it is optimal even in areas of the tool room, which are far away from the inlet opening.
  • the flow cross section may increase, for example, in stages. However, it is advantageous if the flow cross-section increases substantially continuously. It is possible that the flow cross-section increases linearly. But it is also possible that the flow cross section in the direction of the inlet opening is not linear, for example exponentially, to.
  • the tool has on its side facing the dust removal channel wings or other air entrainment means for generating or accelerating the air flow. As a result, the tool can still contribute to a greater extent to the flow in the dust discharge channel.
  • the top wall is advantageously substantially flat. This creates a good flow behavior. It is understood that the respective walls can also have, for example, air guide ribs, channels or the like.
  • the dust removal channel is expediently spirally, i. he has a spiral shape.
  • the dust removal channel extends around a work spindle on which the tool is arranged.
  • the tool room can also have a plurality of inlet openings leading to a dust discharge connection, to each of which a dust removal channel is assigned, of which at least one has a cross section increasing toward the inlet opening.
  • this has at least one next to the tool, for example, a side edge of the tool, arranged inflow opening.
  • the tool has, for example, a distance to a side wall of the cover. It is understood that a plurality of inflow openings can be provided.
  • the tool room is expediently bounded laterally by a side wall of the cover. It is also possible that a separate from the cover side edge cover is provided for lateral delimitation of the tool room.
  • the side edge cover is expediently in front of the side wall in the direction of the work object.
  • the cover and / or the wall segment are expediently tilt-stable in the covering position.
  • the operator does not have to hold the cover or wall segment in the respective position.
  • locking means, weight or the like for a respective determination of the cover or wall segment in the open position or the covering position are possible.
  • a spring arrangement for holding the cover element or the wall segment in the open position or the covering position is advantageous. The operator tilts the cover or the wall segment over a tilt point or dead center. The spring assembly brings and holds the cover or wall segment then in the subsequent open position or covering position.
  • the side edge cover and / or the cover is movably mounted for engagement with the work object with respect to the cover.
  • the cover is expediently firmly connected to the hand-held machine tool, while the comparatively light Seiterirandabdeckung or even the light cover element are movable with respect to the cover.
  • This makes it possible for the side edge cover and / or the cover element to slide optimally along a contour of the work object.
  • the adjustment forces are low due to the lightweight side edge cover.
  • a contact spring arrangement for loading the side edge cover as a whole and / or only of the cover element in the direction of the work object.
  • the abutment spring arrangement "presses" the side edge cover or the cover element in the direction of the work object, so that they rest advantageously on this.
  • the flexible seal may for example comprise a sealing bead and / or a sealing bellows, e.g. plastic, rubber or the like flexible material.
  • the flexible seal comprises a brush.
  • the side edge cover it is basically possible for the side edge cover to include both a brush and a sealing bead, e.g. has at different peripheral portions and / or parallel next to each other.
  • the flexible seal is expediently permeable to air.
  • air inlet openings for example, air inlet openings, a gap below the seal or the like are provided.
  • Air permeability is automatically present in the brush, so to speak. If a sealing bead is provided, it can have, for example, air passage openings or the like. The air permeability allows an inflow of air into the so-called tool room, which is advantageous for effective dust removal, in particular dust extraction.
  • the tool is expediently a grinding tool, for example a grinding pad, which is expediently provided with an abrasive, eg a grinding wheel.
  • the tool can also be a grinding wheel.
  • the invention is in hand machine tools for fine grinding as applicable, as in concrete grinding machines or other grinding machines, which have a strong abrasive effect.
  • the grinding pad or the grinding wheel expediently have passage openings for the passage of air into the dust removal channel.
  • the invention can also be used in manual machine tools for separating work object processing, for example in saws, cut-off grinders or the like.

  • the operation of the tool 21 creates a large amount of dust, which can harm the operator's health.
  • a hood body 29 is connected to the housing 12 substantially rigidly, for example by means of screws 30. At the top of the hood body 29 reinforcing ribs are expediently mounted, which improves its mechanical stability.
  • the housing 12 and the hood body 29 as the main component of the cover 25 expediently form a rigid structural unit. It should be noted that, of course, a flexible mounting of the cover with respect to the housing 12 is possible or an arrangement may be made, in which the hood body forms a part of the housing of a hand-held machine tool. In any case, the position of the tool 21 with respect to the tool space 26 by the rigid connection of the hood body 29 with the housing 12 is clearly defined.
