Definitions

  • the invention relates to a combination tool for performing different operations, in particular drilling and / or screwing.
  • a hole must generally be drilled first. Pre-drilling a screw hole is also recommended for so-called self-tapping screws. Particularly in connection with wooden workpieces, it is also quality-increasing to countersink the corresponding screw holes before screwing in the fasteners, since the fasteners are usually to be completely countersunk and the workpieces in the immediate vicinity of the fasteners are damaged or at least visually impaired without the chamfering of the screw holes can.
  • screwdrivers or correspondingly switchable drills are increasingly used to make work easier.
  • DE-OS 26 20 176 and in the branched DE-PS 26 60 357 it is therefore proposed to connect a drill with a displaceable sleeve in a rotationally fixed manner, which can be pushed back as far as necessary so that the drill bit that can be connected to the drill is released, or can be advanced so far that the cuff grips the head of a screw like a nut and the screw in question can then be screwed in.
  • DE-OS 30 08 394 describes a further screw sleeve, which can also be operated in connection with an impact drill.
  • the invention is based on the object of creating a drilling tool which can be used in particular in conjunction with conventional screwdrivers.
  • the new drilling tool should be able to carry out various types of work.
  • the drilling tool can be connected to the usual coupling sleeves of screwdrivers in a rotationally fixed manner.
  • the pre-drilling of screw holes can be carried out with the same drive machine as the subsequent screwing in of the fastening means.
  • the potentially annoying preparation of a drill and a screwdriver can therefore be dispensed with.
  • the drilling tool can be placed precisely at the desired location on the workpiece. As a result, the otherwise required grain size of the workpiece can often be dispensed with.
  • the coupling sleeves of conventional drive machines are usually provided with resilient latching means which engage in corresponding recesses in coupled tools.
  • a circumferential groove is arranged on the shaft section of the drilling tool, which can be brought into engagement with these locking means. This prevents the tool from falling out of the Coupling sleeve secured.
  • the correct insertion depth of the drilling tool into the coupling sleeve of the drive machine is mandatory. This increases operational safety when using the drilling tool and further facilitates its handling, since the drilling tool is always used with the correct insertion depth.
  • the tool can be designed as a combination tool, in which a drilling section is arranged at one end of the shaft section and a further functional section is arranged at the other end of the shaft section to carry out a further work operation.
  • a drilling section is arranged at one end of the shaft section
  • a further functional section is arranged at the other end of the shaft section to carry out a further work operation.
  • the fact that at least two functional sections for carrying out different work processes are provided in the design as a combination tool means that at least two different work processes can be carried out with only one tool. After the completion of one operation, only the combination tool has to be released from the coupling sleeve of the drive machine, turned over and, conversely, inserted back into the coupling sleeve. Because of this solution, a special tool does not have to be kept ready for each work process. Particularly in the case of successive or directly related work processes, it is advantageous that the additionally required tool is permanently connected to the other tool that is also required. According to claim 5, therefore, a versatile combination tool
  • each functional section is in the area a circumferential groove is assigned to the shaft section.
  • the drilling and screwing operations are particularly advantageously carried out using a single tool. This applies in particular if the screw holes would otherwise have to be pre-drilled using an additional drilling tool.
  • the screw section of the combination tool can be precisely matched to the preferred or present application.
  • the combination tool can also be used in connection with drive machines which do not have a hexagon recess for the rotationally fixed connection with the tool according to the invention.
  • the adapter is provided with a latching element which can be brought into engagement with the circumferential groove or grooves of the shaft section in the manner already described.
  • the adapter can be made shorter overall in the axial direction, since the receiving shaft extends at least partially within the clamping pin. This improves the manageability of a drive machine with an adapter attached, since the correspondingly shortened adapter projects less far in use.
  • At least one latching element is accommodated in a recess that breaks through the jacket of the receiving cylinder and can be moved between a locking position projecting in sections into the hexagon recess and an unlocked position retracted relative to the hexagon recess, and that one for locking the latching element in the locking position
  • On the outside on the receiving cylinder arranged locking sleeve is used, which can be actuated from a position that locks the locking element into a latter in order to avoid it in its unlocking position.
  • the locking element engages in the locking position in a circumferential groove of a tool shank accommodated in the hexagon recess and thereby mediates an axial fixation of such a tool.
  • the locking sleeve can expediently be a sliding sleeve which has an inner radial recess and can be displaced from an axial position which locks the locking element in its locking position into a release position in which the radial recess is located in the region of the locking element. In this position the sliding sleeve can radially deflect the locking element so that it comes out of engagement with the circumferential groove in the tool shaft for decoupling a tool.
  • the radial recess is a bore or perforation that breaks through the casing of the sliding sleeve and that has a cross section equal to or larger than the locking element and that is closed by means of a plug inserted from the outside.
  • the latching element is inserted through the radial recess and then the radial recess is closed by means of a stopper.
  • the receiving cylinder is provided on the outside with axially spaced latching recesses and has the sliding sleeve Radially resilient catches which engage positively in the respective locking recess in the sliding positions of the sliding sleeve which lock or release the locking element and thus impart precise positioning of the sliding sleeve.
  • the object of the invention is also achieved by a combination tool in which two tools, each consisting of a functional section, for example a drilling section, and a shaft section with a hexagonal cross section, are arranged along its longitudinal axis and are connected to one another at their respective shaft sections.
  • two tools each consisting of a functional section, for example a drilling section, and a shaft section with a hexagonal cross section, are arranged along its longitudinal axis and are connected to one another at their respective shaft sections.
  • This solution variant therefore has two separate tools which can be produced independently of one another and can be connected to one another.
  • Such an embodiment simplifies the production of such combination tools, since existing individual tools can be combined to form combination tools.
  • Such tools are expediently put together that are required for successive work steps.
  • the combination tool consists of two separate tools, it is possible to use different materials for the production of the two tools or to process them differently, for example to harden them, in accordance with their respective purpose.
  • a simple and inexpensive way to connect the two shaft sections together is an adhesive connection.
  • Another possible connection is characterized in that the mutually facing ends of the two shaft sections have connecting sections, on which undercuts are arranged for positive engagement with coupling means.
  • the two shaft sections can be connected to one another by such coupling means.
  • the coupling means expediently consists of a connecting part which is equipped with axially opposite coupling recesses, each of which positively engages over the undercut of a shank section and thereby establishes a firm connection to the tool.
  • connection part made of an elastically deformable material, for example plastic
  • the connecting section of the shaft section equipped with the undercut can be inserted into the corresponding coupling recess by light pressure, or can be separated again.
  • the combination tool can be easily repaired in the event of damage to, for example, one of the tools connected to one another.
  • any combination of tools can be put together in this way.
  • the connecting part is provided with a circumferential groove which is guided concentrically around the longitudinal axis of the combination tool.
  • the resilient latching means of a drive machine can engage in this groove in the manner described above.
  • the advantage of this configuration is that there is no need for a corresponding groove in the shaft sections. This makes it easier to manufacture the tools.
  • the entire length of the shaft section between the functional section and the connecting part can be used to absorb the torque of the drive machine.
  • Possible functional sections of a tool include screwdriver bits or taps in addition to the aforementioned.
  • One of the tools can also be equipped with a countersink section with which, for example, pre-drilled boreholes are countersunk.
  • FIG. 1 shows a rotationally symmetrical combination tool 1 which has four distinguishable sections 2, 3, 4 and 5 arranged along its longitudinal axis.
  • a screw section 2 arranged at one axial end is connected via a shaft section 3 to a drilling section 4 at the other axial end of the combination tool 1.
  • a countersink section 5 between the shaft section 3 and the drilling section 4.
  • the screw section 2 is designed in the manner of a Phillips screwdriver.
  • the shaft section 3 has a hexagonal profile, a circumferential groove 6, 7 being provided at the end of the shaft section 3 adjacent to the screw section 2 and at the end adjacent the drilling section 4.
  • the circumferential grooves 6, 7 determine the insertion depth of the combination tool 1 in a conventional - not shown - coupling sleeve of a drill or screwdriver in that the circumferential grooves 6 or 7 enter into a locking connection when the combination tool 1 is inserted into the coupling sleeve with resilient locking means. The combination tool 1 is then secured against falling out.
  • the countersink section 5 and the drilling section 4, like conventional countersinking and drilling tools, have spirally circumferential grooves 10.
  • the tool in deviation from FIG. 1, it is also conceivable to produce the tool merely as a drilling tool with a drilling section 4 and a shaft section 3, without the screw section 2.
  • a drilling tool which can additionally be equipped with a countersink section 5 in the manner described, offers the advantage that it can be connected in a rotationally fixed manner to conventional screwdrivers due to the hexagonal shape of the shaft section 3.
  • a drilling machine for pre-drilling screw holes can be dispensed with entirely. This is a noticeable reduction in workload, particularly in the home and craft sector, and also leads to considerable cost savings.
  • FIG. 3 shows the section of a combination tool 1 in which the formation of a countersink section 5 has been dispensed with and thus the drilling section 4 is connected directly to the shank section 3.
  • the combination tool 1 is connected to a drilling or screwing machine in such a way that the screw section 2 or 2 'and the shaft section 3 are at least partially received in a coupling sleeve or in a suitable adapter 11 of a drive machine.
  • a resilient locking device usually present in such coupling devices engages in the circumferential groove 7 of the shaft section 3 such that the combination tool 1 is inserted into the coupling device with the correct insertion depth and is secured against falling out.
  • the conical design of the drilling section 4 now allows the drilling section 4 to be precisely positioned on the respective workpiece and to pre-drill a required screw hole.
  • the screw hole can be chamfered with the countersink section 5.
  • the desired screw can be inserted into the hole, the combination tool turned around and then inserted back into the coupling sleeve.
  • the correct insertion depth into the coupling sleeve is again predetermined by the other circumferential groove 6 of the shaft section 3.
  • the combination tool 1 is then positively attached to the respective screw with the screw section 2 or 2 'and this screw is then screwed in mechanically with the aid of the drive machine.
  • the screw head can be completely countersunk without any problems, since the corresponding screw hole has already been chamfered.
  • the hexagonal profile of the shaft section 3 provides a rotationally fixed connection between the coupling sleeve of the drive machine and the combination tool 1.
  • Fig. 4 shows an adapter 11 for connecting the combination tool 1 with a conventional chuck of a drill or screwdriver.
  • the adapter 11 has a cylindrical clamping pin 12 which can be connected in a rotationally fixed manner to such a chuck.
  • the adapter 11 On the side facing away from the clamping pin 12, the adapter 11 is provided with a receiving cylinder 13, which has a concentric hexagon recess 14, for receiving the functional section 2, 2 ′ or 4 that is not required in each case and a part of the shaft section 3.
  • the hexagon recess 14 provides a rotationally fixed connection of the adapter 11 with the combination tool 1.
  • the hexagon recess 14 opens into a conical opening (not shown further) within the receiving cylinder 13 for occasional reception of the drilling section 4.
