Definitions

  • the invention relates to a multi-purpose device for operating a drill, screwdriver or the like.
  • Multi-purpose devices for driving a drill, screwdriver or the like are known in various embodiments.
  • those are also known which have electromotive drive devices, the power supply of which takes place either via a supply cable from the respective power supply system or via a rechargeable battery. A power supply of such devices is therefore always necessary.
  • the invention seeks to remedy this.
  • the invention solves the problem of a currentlessly drivable, easy-to-use multipurpose device for operating a drill, screwdriver or the like. to create that is also economically producible ..
  • the invention provides a multi-purpose device for operating a drill, screwdriver or the like, which is designed in such a way that the pistol-like device housing of the multipurpose device in the area of its pistol grip-like handle has a single-armed actuating lever which is pivotably mounted in the device housing, the one with the piston rod of the piston of a working cylinder in the Ge arranged in the interior of the council housing, two further working cylinders having a hydraulic working system is connected, that the working cylinder connected to the actuating lever is connected via a pipeline and a branch pipeline to the two working cylinders, which are arranged at a distance from one another and offset opposite one another, with the pistons, each of which can be pressurized by its own piston Piston rod with a drive wheel carrying a reversing gear, mounted in the device housing with a ratchet mechanism is in operative connection in such a way that the piston rod of the piston of the one working cylinder in the upper region of the drive disc and the piston rod of the piston
  • a multipurpose device designed in this way can be operated by hand and works without current.
  • the drive is activated by means of the hydraulic system and its drive cylinders only by corresponding actuation of the actuation lever in the region of the pistol-like handle shaft in rotation with the drill chuck, the ratchet mechanism provided on the drive disk working in such a way that with a forward stroke of the piston rods of the two working cylinder pistons the drive disk is put into circulation, which in turn drives the drive shaft by means of one of the two bevel gearwheels, while during a return stroke the Piston of the two working cylinders in their initial position by the provided ratchet mechanism, the drive pulley is not in operative connection with the turning gear, so that the turning gear is not taken along when the drive pulley moves backwards.
  • the multipurpose device consists of a pistol-like housing which has a one-armed actuating lever 1 which is pivotably mounted at one end in the device housing in the region of its pistol-like handle.
  • This actuating lever 1 is connected to the piston rod of a piston 2 of a working cylinder of a hydraulic drive system arranged in the interior of the device housing, which comprises two further working cylinders with the pistons 4, 5 and the piston rods connected to the pistons (FIG. 1).
  • the working cylinder with the piston 2 is connected via a pipe 3, which is designed as a branch pipe, to the other two drive cylinders, which have the pistons 4 and 5.
  • This pipeline 3 of the hydraulic drive system consists of flexible or rigid, high-pressure pipes or hoses filled with hydraulic oil.
  • the working cylinders with the pistons 4, 5 are smaller than the working cylinders with the piston 2.
  • the overall arrangement is such that when the piston 2 is advanced by means of the pressure medium in the pipeline 3, the pistons 4 and 5 of the other two drive cylinders are moved forward.
  • the working cylinders with the pistons 4 and 5 are arranged opposite one another and offset from one another in the interior of the device housing.
  • the piston rods of the pistons 4 and 5 are movably mounted or held on these. Due to the opposing arrangement of the two working cylinders with the pistons 4 and 5, the two piston rods of the pistons 4 and 5 are also arranged opposite one another and offset from one another.
  • This drive pulley 6 carries a reversing gear 7, which is designed as a bevel gear with a ratchet mechanism such that if the drive pulley 6 is driven in one direction rotating, then the reversing gear 7 is taken along, while the reversing gear 6 is not taken along when the drive pulley 6 moves back , but remains in its rest position.
  • the turning gear 7 of the drive pulley 6 is in engagement with a further bevel gear 9 or 10, which is offset by 90 °, which is arranged on a drive shaft 8, so that when the drive pulley 6 with the turning gear 7 by means of the pistons 4 and 5 two working cylinders is set in rotation, this rotation on the bevel gear 9 or. 10 is transmitted, which outputs the torque to the drive pulley 8.
  • the drive shaft 8 has at its free end led out of the device housing a drill chuck, designed in a manner known per se, for receiving corresponding working tools, such as drills, screwdrivers or the like. on.
  • a further bevel gear 10 is arranged on the drive shaft 8 at a distance from the first-mentioned bevel gear 9.
  • the arrangement is such that both bevel gears 9 and 10 are arranged on a slide 11 which is displaceable on the drive shaft 8 is adjustable by means of a lever, not shown in the drawing and led out of the device housing.
  • the drive shaft 8 has a square cross section in the travel area of the slide 11.
  • the slide 11 itself is designed as a square hollow body, the inner cross section of which is adapted to the outer cross section of the drive shaft 8, so that the slide 11 arranged on the drive shaft 8 is in frictional engagement with the drive shaft 8, so that when the drive shaft 8 rotates, the slide 11 is taken away (Fig. 2 and 3).
  • the carriage 11 with the two bevel gears 9 and 10 arranged on it can be moved by means of the above-mentioned lever on the outer housing of the device, and it is also possible to determine the lever in its respective position, depending on which of the two bevel gears 9 or 10 is in engagement with the turning gear 7, the drive shaft is subjected to a right or left rotation.
  • This changeover lever itself is connected to the slide by means of a slip ring.
  • the working cylinders arranged in the area of the drive disk 6 have return springs 12 and 13 for their pistons 4 and 5.
  • Another spring 14 is provided in the area of engagement of the actuating lever 1, wherein the arrangement of this spring 14 is such that the actuating lever 1 is moved back into its starting position after actuation by means of a sleeve which can be displaced by the spring 14, with the result that the pressure medium in the working cylinders and the pipeline 3 can expand with the Consequence that the pistons 4 and 5 are moved back to their starting position by means of their springs 12 and 13.
  • this multipurpose device is as follows: When the lever 1 is actuated, the piston 2, which is articulated via its piston rod with the lever, is moved forward and, during this forward movement, presses the pressure medium in the pipeline 3 into the working cylinders arranged in the area of the drive disk 6, such as this that the pistons 4 and 5 are moved forward, at the same time the springs 12 and 13, which act on the pistons 4 and 5 on the pressure-free side, are pressed together.
  • the drive disk 6 is rotated with the turning gear 7, so that, as can be seen in FIG. 1, the bevel gear 9, which is in engagement with the turning gear 7, is also rotated, so that the Drive shaft 8 is rotated.
  • the actuating lever 1 pivots back into its starting position by means of the spring 14, with the result that the pistons 4 and 5 are returned to their starting position by the relief in the interior of the pipeline 3 be moved back, which is supported by the springs 12 and 13.
  • the actuating lever 1 is actuated again.
  • the pistons 4 and 5 are moved forward and the drive disk 6 is rotated again. Because the knar ren Mechanism is only effective when the piston rods of the two pistons 4 and 5 are fed in such a way that the turning gear 7 is in operative connection with the driven drive disk 6, there is a secure non-positive connection to the drive shaft 8.
  • the turning gear 7 is not in engagement with the drive pulley 6, so that during the return movement of the pistons 4 and 5 the drive pulley stands still and does not participate in any rotary movement.
  • a screwdriver a socket wrench for tightening or loosening screw nuts, an Allen key, drill or other tools can be arranged on the drive shaft.
