The disclosure relates to an electronic apparatus for a machine tool, having at least one electronic unit and having at least one fluid cooling unit for cooling the electronic unit using a fluid. According to the disclosure, the electronic unit is arranged at least primarily, in particular completely, outside of a fluid flow path of the fluid cooling unit.

Electronic apparatus and machine tool having said electronic apparatus

A quick clamping device for arranging at least one application tool on a power tool, in particular on an angle grinder, includes at least one output unit for moving the application tool about an output axis of the output unit, and at least one fixing unit having at least one movably mounted fixing element that is mounted, in particular in a non-removable manner, on the output unit, at least for axially fixing the application tool to the output unit. The quick clamping device has at least one securing unit, which has at least one, in particular movably mounted, securing element that is intended to secure the fixing element, which is mounted so as to be movable relative to the output unit at least about the output axis, so as to prevent the fixing element from moving about the output axis.

Quick clamping device

A handheld power tool device for a handheld power tool, in particular a sander, preferably an orbital sander or a random orbital sander includes a housing unit, which has a handle housing and a drive housing for holding a drive unit. The drive housing defines a drive axis of the drive unit. The power tool device further includes a damping unit which couples the drive housing to the handle housing. The drive housing includes an extension arm, which extends at least radially with respect to the drive axis and on which at least a portion of the damping unit is arranged.

Handheld power tool, in particular a sander, handheld power tool device, protective device, handheld power tool system, and method for manufacturing a handheld power tool device

A machine tool, in particular a hand-held machine tool, is disclosed. The machine tool includes at least one housing unit and at least one drive unit arranged within the housing unit. The machine tool further includes at least one separator unit which is provided to divide at least one fluid flow directed through the housing unit into at least two sub-flows, in particular according to a density of foreign bodies. One sub-flow of the sub-flows has a higher density of foreign bodies in comparison to another sub-flow of the sub-flows. The machine tool also includes at least one fluid cooling unit which is provided for cooling the drive unit by way of the at least two sub-flows.

Machine tool and method for cooling a drive unit of the machine tool

A handheld power tool includes an output shaft, a drive unit, a securing ring, and a securing element. The output shaft is configured to be releasably connected to an insert tool of the handheld power tool. The drive unit is configured to transmit a movement to the output shaft. The securing element is configured to secure the securing ring. The securing element has a recess which is provided to surround the securing ring in the radial direction in at least one operating state.

Handheld power tool

A portable power tool, in particular an angle grinder, includes a housing that accommodates a drive and an electronic device with an interface configured to electrically connect the electronic device. The power tool further includes a housing inner part that is configured as a drive housing and supports the electronic device. The interface has at least one first electrical interface contact region and at least one second interface contact region spaced apart from the first interface contact region. At least one insulating element spaced apart from the interface contact regions is arranged between the housing inner part and the electronic device. The insulating element is configured to avoid an electrical short-circuiting connection between the first interface contact region and the second interface contact region.

Portable power tool

A work shoe, in particular a safety shoe, includes at least one passive protection unit which is intended to passively protect a shoe wearer at least against mechanical and/or electrical loads, and includes at least one active protection unit which has at least one sensor unit which is intended to detect at least one characteristic variable at least in order to enable a protection function and/or a comfort function. The sensor unit is configured at least for detecting at least one person-related characteristic variable and/or at least one environmental characteristic variable.

Work shoe

A machine-tool operating device includes at least one operating unit and at least one electronics unit. The at least one operating unit has at least one operating element that is configured to be actuated by an operator and at least one further operating element that is configured to be actuated by an operator. The at least one electronics unit is configured at least for switching at least one energy supply of a drive unit in accordance with actuation of the operating element and of the further operating element. One or more of the operating element and the further operating element are configured as a touch-sensitive electronic operating element.

Machine-tool operating device

An optical indicating device unit includes at least one first housing, a mechanical interface, and a data interface. The at least one first housing includes at least one illumination device and/or at least one optical device, wherein the at least one illumination device and/or the at least one optical indicating device is configured to visually indicate information. The mechanical interface is configured to connect the at least one first housing to a second housing. The data interface is configured to transmit information to the at least one illumination device and/or the at least one optical indicating device.

Optical display device unit for use in an external application unit

A fastening unit for a radio and/or a sensor module includes at least one of a radio and a sensor module that is configured to connect with an external application unit. The fastening unit is detachably connectable to the at least one of the radio and sensor module.

Fastening unit for a radio and/or sensor module

A handheld power tool includes at least one housing unit, at least one tool receptacle, at least one operating unit that has at least one operating element, and at least one electrical and/or electronic indication unit. The indication unit has at least one at least partially circumferentially arranged indication element that is configured to indicate at least one handheld power tool characteristic variable. The indication element in one embodiment is arranged on the housing unit in a region between the operating element the tool receptacle The indication element in another embodiment is arranged at least substantially adjacent to the operating element.

A hand-held power tool, in particular an angle-grinding machine, includes a housing, a switching unit, a motor, and at least one first pivot unit and one second pivot unit. The switching unit includes a ratchet element arranged on the housing. The first and second pivot units are configured to mount the ratchet element on the housing so as to be movable. Each of the first and the second pivot units includes at least one housing-side bearing unit and one ratchet-side bearing unit. The hand-held power tool further includes a coupling unit configured to couple the first pivot unit with the one second pivot unit.
