Definitions

  • the present invention relates to a machine tool for chiselling and optionally for drilling, in particular a hand tool.
  • a motor-driven pneumatic percussion in a hand tool should deploy a chiselling effect as soon as possible when placed on a workpiece.
  • the strokes of the impact mechanism go into the void and the energy of the shocks is transferred into damping elements and a housing of the power tool.
  • the resulting increased burden of the power tool and the user should be avoided by switching off the pneumatic percussion.
  • a pneumatic percussion with a pot-shaped exciter cylinder requires a high accuracy of fit in each other moving elements, ie guide tube, exciter cylinder and flying piston to ensure a largely airtight seal through the adjacent walls of the respective elements.
  • the elements must have sufficient mechanical stability, in particular during the striking operation.
  • One object consists in a pneumatic impact mechanism with an improved mechanical stability, which enables a reliable switching on and off of the percussion mechanism.
  • the machine tool includes a pneumatic striking mechanism which has a cup-shaped exciter cylinder with an open interior in the direction of impact and a movable in the interior of the air piston. In a shell-shaped wall of the interior, a recess and spaced from the recess in the direction of impact at least one ventilation opening are provided.
  • the flying mass includes a sealing element which seals the at least one ventilation opening when the sealing element is opposite the at least one ventilation opening and which is spaced from the jacket-shaped wall in the region of the depression when the sealing element is opposite the recess.
  • the sealing element seals a pneumatic space between the flying piston and the exciter cylinder.
  • the sealing element touches the jacket-shaped wall of the interior.
  • the recess allows venting to compensate for the air losses of the pneumatic space by air in the region of the wells can flow past a flying piston, during the period of time that faces the sealing element of the recess. Parasitic ventilation when the ventilation openings pass through the sealing element is prevented by the sealing element being designed to seal the ventilation openings.
  • the depression has a depth which, in contrast to the ventilation openings, is less than a wall thickness of the exciter cylinder.
  • the recess thus allows only a flow of air along the direction of impact.
  • the ventilation openings are designed to allow a flow of air in the radial direction, substantially perpendicular to the impact direction.
  • a dimension of the recess is greater than a dimension of the at least one ventilation opening.
  • the dimensions, i. the width, are each determined along the direction of impact.
  • the width of the recess may for example be at least twice as large as the width of the ventilation opening.
  • the recess is annular.
  • An annular recess leads to an axially symmetrical weakening. It turns out that acting forces up The exciter cylinder can thereby advantageously lead to only a slight change in its shape and its accuracy of fit.
  • An embodiment provides that at least three, preferably at least four or at least eight of the ventilation openings are arranged in a plane perpendicular to the direction of impact.
  • the ventilation openings can be arranged in the same angular distribution about an axis of the impact mechanism to allow a more dimensionally stable structure.
  • the ventilation openings may also be arranged in a plane or spirally.
  • An embodiment provides that a drive for periodic movement of the exciter cylinder is provided by a lifting height along the direction of impact and a distance of the recess to the at least one ventilation opening is less than half the lifting height.
  • the pneumatic space can already be vented immediately with a blank.
  • the exciter cylinder is typically still advanced in its in the direction of impact far advanced position and the flying piston on the normal point of impact.
  • the movable air piston has an air channel for connecting sides, which are opposite in the direction of impact, of the air piston, which is interrupted by the sealing element.
  • the machine tool has a guide tube, within which the exciter cylinder is movably arranged, wherein the guide tube has an outlet opening with a front edge in the direction of impact, wherein at a dead stop the sealing element in the direction of impact behind the front edge and in striking position in front of the front edge is.
  • An air flow through the vent opening can be designed depending on the relative position of the flying piston to a guide tube. The opening and closing depending on the relative position can be used especially for a targeted ventilation after a blank or to start the pneumatic percussion.
