Control device for a hand-held power tool
A hand-held power tool, in particular to a screwing device, includes a control device for controlling and/or regulating the tool movement of a tool holder and/or of a tool. The hand-held power tool has an interface for communicating with an external adjustment device. The interface is configured to be connected to the control device in such a way that signals may be transmitted for the parameterization of at least one tool movement sequence. The tool movement sequence includes a plurality of sequentially-progressing tool movements. A method for parameterizing at least one tool movement sequence of a hand-held power tool includes parameterizing the at least one tool movement sequence with a separate setting device in a remote-controlled manner via an interface of the hand-held power.
1. A hand-held power tool, comprising:
a portable hand-held housing;
a drive device accommodated in the housing;
one or more of a tool holder and a tool configured to be driven by the drive device,
a control device accommodated in the housing and connected to the drive device, the control device being configured to control the drive device using one or more of open-loop control and closed-loop control so as to cause the drive device to drive the one or more of the tool holder and the tool to perform at least one tool movement sequence, the at least one tool movement sequence being defined by prespecified parameters, and
an interface supported by the housing and configured to communicate with an external setting device, the interface being connected to the control device for signaling purposes,
wherein the control device is configured to receive the prespecified parameters from the external setting device via the interface,
wherein the at least one tool movement sequence comprises a plurality of sequential tool movements.
2. The hand-held power tool as claimed in claim 1 , wherein the interface is an air interface configured for cable-free parameterization by the external setting device.
3. The hand-held power tool as claimed in claim 1 , further comprising a drive device configured to generate the tool movement, the control device being connected to the drive device for signaling purposes and configured to subject the tool movement sequence to the one or more of open-loop control and closed-loop control.
4. The hand-held power tool as claimed in claim 3 , wherein the drive device has an electrical machine which drives the one or more of the tool holder and the tool, the control device being connected to the electrical machine for signaling purposes and configured to subject the tool movement sequence to the one or more of open-loop control and closed-loop control.
5. The hand-held power tool as claimed in claim 4 , further comprising a clutch which is interconnected between an output drive of the electrical machine and the one or more of the tool and the tool holder, the control device being connected to the clutch for signaling purposes and configured to subject the tool movement sequence to the one or more of open-loop control and closed-loop control.
6. The hand-held power tool as claimed in claim 1 , wherein the control device and the drive device are connected for signaling purposes in a regulator-free system and configured to control at least one tool operating variable.
7. The hand-held power tool as claimed in claim 6 , wherein the tool operating variable is one or more of a position, a movement direction, a speed, and an acceleration of the one or more of the tool and the tool holder.
8. The hand-held power tool as claimed in claim 6 , wherein the tool operating variable is one or more of a disconnection force and a disconnection torque of the tool.
9. The hand-held power tool as claimed in claim 6 , further comprising at least one operating element configured to select one of the one or more of the tool movement sequences and the tool operating variables.
10. The hand-held power tool as claimed in claim 1 , further comprising at least one operating element configured to operate the hand-held power tool.
11. The hand-held power tool as claimed in claim 1 , wherein the control device has a computation device (CPU) and a data memory device.
12. The hand-held power tool as claimed in claim 1 , wherein the interface is connected for signal purposes to the control device by a further line in order to parameterize at least one tool movement sequence and/or to set at least one tool operating parameter.
13. The hand-held power tool as claimed in claim 12 , wherein the interface is also connected to a signaling device accommodated by the portable hand-held housing, the signaling device being configured to provide a user of the hand-held power tool with information relating to data transmission between the external setting device and the hand-held power tool and/or about which movement sequence is currently parameterized.
14. The hand-held power tool as claimed in claim 1 , wherein the interface is accommodated in the portable hand-held housing.
15. A method for parameterizing at least one tool movement sequence of a hand-held power tool, comprising:
parameterizing the at least one tool movement sequence for the power tool with an external setting device, the power tool including a portable hand-held housing in which a drive device and a control device for the power tool are accommodated, the external setting device being located externally with respect to the housing;
communicating the parameterized tool movement sequence to the control device via an interface on the power tool; and
controlling the drive device to execute the parameterized tool movement sequence with the control device;
wherein the at least one tool movement sequence includes a plurality of sequential tool movements.
