Definitions

  • the present invention relates to a machine tool with a tool that can be driven by a shaft device and a motor, a position of the shaft device being defined by a shaft axis A1 and a position of the motor being defined by a motor axis A2, the machine tool being used to supply energy with at least a replaceable energy supply device can be connected and the shaft axis A1 runs essentially parallel or collinear to the motor axis A2.
  • drilling devices in particular core drilling devices, are known with which essentially cylindrical drill cores can be cut out of a subsurface.
  • Core drilling devices for example, have drill bits as tools that can be driven to rotate by the core drilling device.
  • mains-operated core drilling devices are known in the prior art, which draw their energy from a power network.
  • This can be, for example, a public power grid or a construction site power grid.
  • the disadvantage of the known mains-operated core drilling machines is that they are often uncomfortable to use due to the cabling.
  • the power cord is often "in the way", so in some cases it even poses a safety risk.
  • Another safety risk can arise from the interaction of electricity with cooling or flushing water used when drilling a core.
  • the operation of such a mains-operated core drilling device is only possible in those areas of a construction site where electrical energy is available in the form of a mains connection.
  • Another disadvantage of power cords is that they are often damaged. For example, they can become trapped or damaged when drilling. As a result, they can pose a safety risk for the machine tool itself or for the user.
  • the drilling devices which are known from the prior art, can either be held by a user ("hand-held”) or attached to a drill stand during operation (“stand-held”). There are devices that are intended for both types of use (universal drilling rigs) and devices that are only hand-held or stand-mounted can.
  • the drilling devices which can at least also be operated on a stand, often have an interface for connecting the device to a drill stand.
  • this drill stand interface is often located on the underside of the drilling rig.
  • this arrangement of the drill stand interface on the underside of the drilling device can make handling the machine tool more difficult, especially if the drilling device is designed as a battery-operated drilling device.
  • Battery positioning may require a greater distance between the drill stand interface and the drill stand.
  • the greater distance between the drill stand interface and the drill stand can disadvantageously reduce the rigidity of the system consisting of the drill stand and drilling device or it can happen that existing accessory material can no longer be used.
  • the object on which the present invention is based is to overcome the shortcomings and disadvantages of the prior art described above and to provide a machine tool that can be used particularly flexibly, conveniently and safely on a construction site.
  • the machine tool should be able to be used simply and easily in all areas of a construction site.
  • experts would welcome it if the machine tool to be provided could be designed to be particularly compact and handy, so that even long-term work with the machine tool is perceived as being as little stressful as possible for a user.
  • a machine tool with a tool can be driven by a shaft device and a motor, with a position of the shaft device being defined by a shaft axis A1 and a position of the motor being defined by a motor axis A2.
  • the machine tool can be connected to at least one replaceable energy supply device, with the shaft axis A1 running essentially parallel or collinear to the motor axis A2.
  • the shaft device with the shaft axis A1 can be referred to as the “output shaft” and the shaft device with the motor axis A2 as the motor shaft.
  • the machine tool can preferably be referred to as a “machine tool with essentially parallel output and motor axes”.
  • the motor axis A2 preferably defines the position or arrangement of the motor within the machine tool.
  • the replaceable energy supply device can in particular be a rechargeable battery or an accumulator (“rechargeable battery”), with the machine tool drawing its energy from the at least one replaceable energy supply device.
  • the machine tool can have one or two interchangeable energy supply devices.
  • the energy supply devices are interchangeable in the sense that an “empty” battery can be removed from the machine tool in order to be charged - for example in a charger. Instead of the “empty” battery, a “fresh”, ie fully charged, battery can be inserted into the machine tool to ensure the power supply to the machine tool.
  • the machine tool can be used particularly flexibly because its operation does not depend on the presence of a mains connection.
  • the safety when operating the machine tool is significantly increased, as any power cables are no longer a “tripping hazard”.
  • possible sources of danger such as damaged cables that come into contact with cooling or rinsing water, are eliminated by eliminating the need for a power cable in the machine tool with the replaceable energy supply device.
  • the machine tool has a device for receiving the at least one replaceable energy supply device.
  • the device for receiving the at least one replaceable energy supply device preferably represents a receiving device or interface, which can also preferably be referred to as an “energy interface” in the sense of the invention.
  • the energy interface is preferably located inside the machine tool, so it is not shown in the figures.
  • the replaceable energy supply device is designed as a network adapter.
  • the term “mains adapter” is understood in the sense of the invention as a device that enables the battery-operated machine tool to be supplied with energy via a power network.
  • the power adapter can have a similar shape to a battery and can be integrated into the power interface of the machine tool fit. In other words, the power interface of the machine tool can be set up to accommodate rechargeable batteries and/or power adapters.
  • the power adapter also has a power cable for connecting the power adapter to a power network. If, during operation of the machine tool, it turns out that the battery of the machine tool is “empty”, the battery can be removed from the machine tool and replaced with the mains adapter.
  • the mains adapter advantageously ensures the power supply to the machine tool, with the mains adapter being available in particular as an “emergency reserve” or “fallback option” if the energy supply of the machine tool's battery is used up surprisingly quickly or if the battery is defective or otherwise way is unusable.
  • the mains adapter can also be used, for example, if a large number of core drillings are to be carried out for which the energy from one or more batteries is not sufficient.
  • the mains adapter can therefore help to increase the range of the machine tool, while a power supply device designed, for example, as a battery can help to provide a machine tool that can be used particularly flexibly.
  • the machine tool comprises a first housing and a second housing, wherein the first housing is designed to at least partially enclose the motor and the second housing is designed to at least partially enclose the replaceable energy supply device.
  • the first housing is preferably also referred to as a “motor housing”, while the second housing can be referred to as a “battery housing”.
  • the provision of two housings enables particularly good protection of the individual components of the machine tool. This can advantageously extend the service life of the machine tool or a maintenance interval between two maintenance processes.

  • the shaft axis A1 and the motor axis A2 run essentially parallel or collinear to one another.
  • the position of the tool of the machine tool can also be described with the help of the shaft axis A1, since the tool can be connected to the shaft device in order to be driven.
  • substantially parallel or collinear does not represent an unclear term for the person skilled in the art, because the person skilled in the art knows that axes that are essentially parallel or collinear can have slight deviations from the mathematically exact parallelism or collinarity, which can occur, for example, due to manufacturing. Such deviations can be in a range of +/- 5°, for example.

  • the insertion direction E can be oriented essentially perpendicular to the shaft axis A1 and/or the motor axis A2.
