Definitions

  • the invention relates to a screwing device according to the preamble of patent claim 1.
  • the Torque clutch is composed of a first clutch part, a second coupling part and one arranged between the two coupling parts Intermediate coupling part.
  • the first coupling part is designed as a gear and is in non-rotatable connection with a drive motor.
  • the second coupling part stands with one Tool spindle in connection, a screw-in tool at the free end on the direction of rotation records.
  • the intermediate coupling part rotatably arranged on the tool spindle is disc-shaped and is used for torque transmission from the first coupling part to the second coupling part.
  • the invention has for its object to provide a screwdriver that is economical can be produced and quickly and securely screwed into an underground can be turned.
  • the one pointing in the direction of rotation is advantageous Stop of the tool spindle of a in a circumferential groove Tool spindle arranged circlip formed.
  • the second coupling part expediently points on the in the direction of rotation facing side has a locking contour in the form of a tooth-shaped profile, in the starting position of the tool spindle with a positive fit corresponding locking contour of the housing interacts.
  • FIG Housing 1 The part of a screwing device according to the invention shown in FIG Housing 1, one via a threaded connection, opposite the housing 1 parallel to Depth stop 2 adjustable in the direction of rotation, one relative to the housing 1 displaceable tool spindle 8, a drive motor, not shown, with a Drive shaft 7 and one between the tool spindle 8 and the drive shaft 7 arranged torque clutch 3.
  • the tool spindle is located at an end region facing away from the torque clutch 3 8 with a tool holder 9 in connection.
  • This tool holder 9 protrudes with a hexagonal insertion end in a blind hole in the tool spindle 8 and is secured axially by means of a spring-loaded ball.
  • the free end of the tool holder 9, which is opposite the insertion end, is also with a Blind hole provided that the inclusion of a screwing tool 14 in the form a screw bit is used.
  • This screw bit protrudes into a cross-slit Receiving area of a screw 12 which is screwed into a base 13 shall be.
  • the torque clutch 3 has a first clutch part 4 and a second clutch part 6 and an intermediate coupling part 5.
  • the first coupling part 4 is rotatable, but axially firmly mounted on the tool spindle 8 and has a tooth-shaped on its peripheral contour Profiling on the form-fitting with a corresponding counter-profiling the drive shaft 7 of the drive motor cooperates.
  • On one in the direction of rotation facing side of the first coupling part 4 protrudes at least one cam 41 which positively with at least one further cam 51 of the intermediate coupling part 5 is connectable.
  • the second coupling part 6 is fixedly connected to the tool spindle 8 and projects beyond it the outer contour of the same radially.
  • a locking contour 61 which in the starting position of the screwdriver with at least one corresponding one Interlocking contour 11 of the housing cooperates.
  • the locking contours 61, 11 can be formed, for example, by tooth-shaped profiles.
  • the intermediate coupling part 5 is freely rotatably mounted on the tool spindle 8 and due to a stop 81 of the tool spindle 8 against the direction of rotation only limited transfer.
  • the stop 81 is formed by a locking ring, which in a circumferential groove of the tool spindle 8 protrudes.
  • a spring element 15 in the form of a Coil spring arranged, which in the starting position of the screwing device Intermediate coupling part 5 spaced from the second coupling part 6 against the stop 81 presses.
  • first coupling part 4 and the tool spindle 8 Spring 10 also arranged in the form of a helical spring, which the tool spindle 8th in the starting position of the screwing device into a position on the direction of rotation presses in the cams 41, 51 of the first coupling part 6 and the intermediate coupling part are axially spaced apart.
  • the screwdriver Before the screwing-in process begins, the screwdriver is in one Starting position according to FIG. 1, in which all coupling parts 4, 5, 6 of the Torque clutch 3 are axially spaced apart.
  • the drive motor In the subsequent actuation of an actuation switch, not shown the drive motor, which is also not shown in full, begins to rotate. Whose Rotational movement or torque is generated via the drive shaft 7 of the drive motor the first coupling part 4 and from there via the intermediate coupling part 5 to the second Coupling part 6 and thus transferred to the tool spindle 8.
  • the flanks of the claws 52, 62 run essentially parallel to Direction of rotation.
  • the first coupling part 4 rotates relative to the intermediate coupling part 5 until the axial projections of the cams 41, 51 no longer cover. Because at this point in the direction of rotation no more force the intermediate coupling part 5 acts, the prestressed spring element 15 relax between the intermediate coupling part 5 and the second coupling part 6 and push the intermediate coupling part 5 to the first coupling part 4.
  • the cams 41, 51 and the claws 52, 62 different extents T1, T2, the two claws 52, 62 come out of engagement and into a position in which they are axially spaced apart at a distance T3, so that even with a continuous rotary movement of the first coupling part 4 and Intermediate coupling part 5 no more rotary movement on the tool spindle 8 can be transferred.
  • the distance T3 corresponds to the difference between the extension T2 of the cams 41, 51 and the extension T1 of the claws 52, 62.
