Definitions

  • the tool spindle is only then connected to a drive, when a driven by the tool spindle fastener against a workpiece is pressed.
  • the tool spindle against a spring force against a housing axially displaced while the take-up clutch engaged. in the unloaded state is the driving clutch, however, due to the on the tool spindle acting spring force out of engagement.
  • This separate in the unloaded state driving clutch is advantageous in screwing operations to ensure safe engagement of the screwdriver bit to ensure in the screw head.
  • the drilling adapter to screwdrivers to use, which have a normally separate driving clutch. It comes when inserting the Aufsteck Schemees in the receiving space of the axial stop of the steep element in contact with the tool spindle. This will now be attached further of the drilling adapter on the screwdriver is moved through the axial stop until the driving clutch engaged. Now the slip-on sleeve over the engagement body with the attachment area be brought into engagement of the screwdriver. Since the axial stop opposite the slip-on sleeve is axially fixed, the driving clutch is due to the positive connection between the slip-on and the screwdriver permanently and stably engaged held. In this way, when attached Bohradapter a direct drive of Tool spindle achieved. Thus, the drill adapter is also in connection with screwdrivers, which have a normally separate driving clutch, usable in a comfortable manner.
  • the at least one engagement body is in a transverse opening of the slip-on sleeve mounted, whose length is smaller than a longitudinal extent of the engagement body in the direction the transverse opening is.
  • the adjusting body is formed by a ring element, which on the Push-on sleeve is pushed and with an oblique annular surface, which is attached to the engagement body can be applied, an inner cone limited, wherein between the ring member and the slip-on an axial spring, which is also pushed onto this, acts.
  • a shaped Ring element can be made a particularly stable positive connection and a tilt-free Move the adjusting body can be achieved.
  • this is a convenient Holding the Bohradapters possible with simultaneous operation of the fixing device what the attachment of the Bohradapters on the screwdriver much easier.
  • the driving clutch 10 in this case has a first coupling part 14, which on the tool spindle 12 is rotatably mounted and meshes with the drive pinion 8.
  • a second Coupling member 16 of the driving clutch 10 is rotatably connected to the tool spindle 12.
  • the two coupling parts 14, 16 have claws 18 which by moving the second coupling part 16 relative to the first coupling part 14 in and out of engagement can be brought.
  • the tool spindle 12 is displaceable in a housing 20 of the Bolt 4 stored.
  • a Coil spring 22 is provided which presses apart the two coupling parts 14, 16.
  • bit receptacle 24 On a side facing away from the driving coupling 10 end of the tool spindle 12 has this one bit receptacle 24 with hexagonal cross section.
  • the bit receptacle 24 is in Axial direction bounded by a bottom 25.
  • Screwdriver bits protrudes a clamping ball 26 partially into the bit holder 24th
  • a total of 28 designated drilling adapter is attached, the essentially of a slip-on sleeve 30, a chuck 32 and one by a plunger 34 formed torque transmission device consists.
  • the drill chuck 32 is included can be mounted on the plunger 34 via a screw connection and can therefore be exchanged at any time become.
  • the plunger 34 itself is rotatable about a ball bearing 36 but in the direction an axis A of the drilling adapter 28 immovably mounted on the slip-on sleeve 30.
  • the slip-on sleeve 30 partially defines a receiving space 38, which has an opening 40.
  • a receiving space 38 into the ram 34 protrudes with a spigot 42, which has a cross section adapted to the receiving cross section of the bit holder 24 is.
  • From this insertion end 42 projects a stop element 44 in the direction of the opening 40, whose free end forms an axial stop 46.
  • the stop element 44 has while a stop cross section, which is smaller than the cross section of the insertion 42nd is, which is engageable with the bit holder 24 an engagement.
  • transverse openings 48 At the slip-on sleeve 30 are three transverse openings 48 at angular intervals of 120 ° formed in the radial direction of the receiving space 38 with an outer side 50 of the Connect slip-on sleeve 30. As shown in dashed lines for a transverse opening 48, these serve for receiving an engagement body 52 in the form of a sphere whose diameter is larger as the length of the transverse opening 48.
  • an actuating sleeve 54 is provided, which is on the slip-on 30 is pushed and is mounted relative to this displaceable in the axial direction.
  • an annular actuating body 58 is formed, which rests against the outside 50. This has a fixed position in which he auf axial height of the transverse opening 48 is and can be brought into contact with the engagement body 52, and a release position in which it is axially spaced from the transverse opening 48.
  • the slip-on 30, serves as part of a fixing device, in a mounting direction B on a slip-on 66, which is formed on a surface 67 of a device neck 68, pushed.
  • the receiving space 38 of the slip-on sleeve 30 in size and shape to the attachment area Adjusted 66 of the screwdriver 4.
  • Axialaufsum formed 72 when mounting the Bohradapters 28 for Receiving axial ribs 74 serve formed on the surface 67 of the device neck 68 are.
  • an annular groove 76 is inserted, which normally for fixing a depth stop, not shown, is used. In determining the Bohradapters 28 this is used to partially receive the engagement body 52.
  • the actuating sleeve 54 moved back in the mounting direction B and at the same time the slip-on 30 in opposite Direction pulled from the device neck 68.
  • the engagement body 52 slip out of engagement with the annular groove 76 through the transverse opening 48 until it partially into the Release chamber 60 protrude. They give the receiving space 38 free to the neck of the device 68th to be able to move out of it.
