Description

The present invention relates to a receiving device for an electronic device with a receiving device designed for receiving or arranging the electronic device and a fastening device for connecting the receiving device to a housing of the machine tool according to the preamble of claim 1 and an assembly comprising a housing of a machine tool and such a receiving device according to claim 13.

In practice, receptacles are well known which have receptacles designed to hold electronic components of machine tools, the receptacles for example protecting the electronic components from dust and particles. The receiving devices in which the electronic components are arranged can be fixed by means of, for example, two screws on fastening domes of a housing of the machine tool.

The respective holding device is designed for a specific housing of a machine tool, so that, for example, different holding devices have to be provided for different machine tools.

It is an object of the present invention to provide a receiving device for an electronic device and an assembly comprising a housing and such a receiving device, the receiving device having increased flexibility in a structurally simple manner.

This object is achieved with a holding device for an electronic device, in particular a machine tool, with a holding device designed to hold the electronic device, in particular in the form of a cup, and with a fastening device for connecting the holding device to a housing of the machine tool in that a displacement device is provided which is equipped with a displacement mechanism is connected to the receiving device so that the receiving device can be displaced relative to the displacement device, a blocking device or positioning device cooperating with the displacement mechanism and coupled to the displacement device being provided, the displacement device being connectable to the housing of the machine tool by means of the fastening device, and wherein the Blocking device in the state of the fastening device connected to the housing of the machine tool ls the fastening device can be fixed on the displacement mechanism and thereby a displacement of the displacement device relative to the displacement mechanism can be prevented.

A receiving device designed according to the invention has the advantage that the receiving device can be displaced relative to the displacement device, so that the receiving device can be flexibly arranged depending on the available installation space and can be used in different machine tools depending on the available installation space. In particular in one step with the attachment of the receiving device, for example to a fixing dome of the housing, the fixing device can determine a position of the receiving device with respect to the displacement device, for example by jamming the blocking device on the displacement mechanism. As a result, both the fastening of the receiving device to the housing and a fixing of a position of the receiving device relative to the displacement device can be achieved in a structurally simple manner in a single working step.

In a simple embodiment of the receiving device, the displacement mechanism is designed as a rail with a T-shaped cross section, for example. Alternatively, the displacement mechanism can also be designed as a backdrop, for example.

The displacement mechanism is, in particular, firmly connected to the receiving device and is preferably embodied integrally with the receiving device. As a result, the displacement mechanism can be produced in a simple and inexpensive manner.

The displacement device and the blocking device preferably each have a region encompassing the rail, with both the displacement device and the blocking device preferably being designed with an upper hook element and a lower hook element, which are each designed to engage behind the T-shaped leg of the rail . A distance of the upper hook element to the lower hook element in the longitudinal direction of the fastening device is preferably greater in the blocking device than in the displacement device. In a state of the blocking device which enables the receiving device to be displaced relative to the displacing device, an upper hook element of the blocking device is in particular spaced apart from the rail or has play relative to the rail, so that the displacing device can be displaced in a structurally simple manner relative to the displacing device and the blocking device is enabled.

The displacement device preferably has two regions in the longitudinal direction of the displacement mechanism, each of which cooperates with the displacement mechanism, the blocking device being arranged in the longitudinal direction of the displacement mechanism between the regions of the displacement device and with the displacement mechanism cooperates. In this way, a favorable force transmission from the blocking device to the displacement device is created, since the displacement device can be supported on the blocking device with one region or with the other region in the longitudinal direction of the displacement mechanism, depending on the external force applied.

If the blocking device can be displaced relative to the displacing device perpendicular to the longitudinal direction of the displacement mechanism in the main direction of extension of the fastening device, the blocking device can be displaced between a blocking state and a released state in a simple manner. For this purpose, the blocking device can have at least one, in particular two grooves, in which a pin-shaped area or areas of the displacement device engage or engage.

The blocking device is preferably mounted with a region within a region of the displacement device, a passage opening for the fastening device being provided in each of these regions of the blocking device and the displacement device. As a result, a fixing or jamming of the blocking device with respect to the rail can be achieved in a structurally simple manner when the receiving device is fixed on the housing, which also causes the displacement device to be displaced relative to the displacement mechanism. The through openings can be designed as tapered through holes.

In order to achieve a favorable introduction of force from the fastening device into the blocking device, the blocking device can have a shoulder designed to interact with a head of the fastening device.

In a simple embodiment, the fastening device is designed as a screw or rivet.

In a preferred embodiment, the displacement mechanism is arranged on a side wall of the receiving device and preferably extends over an entire length of the side wall of the receiving device to achieve a large possibility of displacement of the receiving device relative to the displacement device.

A reliable support of the receiving device on the housing of the machine tool can be achieved if the receiving device has a further displacement mechanism on a side wall, in particular opposite the side wall, which interacts with a further displacement device, a further blocking device and a further fastening device, in particular to the extent described in more detail above.

Good protection of electronic components which can be arranged in the receiving device can be achieved if the receiving device has a plate-shaped base body and at least one side wall projecting essentially perpendicularly therefrom. The receiving device is in particular cup-shaped and preferably forms an interior for receiving at least some of the components of the electronics. The receiving device, which is in particular made in one piece or in one piece, has in particular a rectangular cross section, but can also have cross sections of different design.

An assembly comprising a housing of a machine tool and such a holding device is also proposed, the housing of the machine tool having at least one screw-on dome or fastening dome, on which the holding device can be fixed by means of the fastening device, the blocking device and the displacement device.

An assembly designed according to the invention has the advantage that the holding device can be moved relative to the moving device, so that the holding device can be arranged flexibly depending on the available installation space and can be used with different machine tools. In particular in one step with the attachment of the receiving device, for example to a fixing dome of the housing, the fixing device can determine a position of the receiving device relative to the displacement device, for example by jamming the blocking device on the displacement mechanism. As a result, both the fastening of the receiving device to the housing and a fixing of a position of the receiving device relative to the displacement device can be achieved in a structurally simple manner in a single step.

Examples:

In 1 to 4 In each case, an assembly 1 is shown, which has a housing 2 of a machine tool, which is shown only partially and schematically. Electronic components which are sensitive to dust and particles are provided in the housing 2. In order to protect them at least in some areas, the assembly 1 has a holding device 5 with a holding device 8 provided for arranging and holding the electronic components.

The receiving device 8 is formed here with a substantially plate-shaped and in this case rectangular basic body 9, with four side walls 10, 11, 12, 13 bordering an edge region of the basic body 9 perpendicular to the basic body 9, which here are embodied integrally with the basic body 9 are. The receiving device 8 is cup-shaped here, an interior 15 being delimited by the base body 9 and the side walls 10, 11, 12, 13, in which the electronic components can be arranged and are at least partially protected from external influences.

In order to be able to arrange the receiving device 5 on the housing 2, the housing 2 here has two fastening domes 17, 18 or screw-on domes, each of which is designed with an internal thread.

The receiving device 8 has here on the side wall 10 a displacement mechanism 20 designed as a rail, which in the present case extends essentially over the entire longitudinal extent of the side wall 10. The rail 20 has a T-shaped profile with a web 22 projecting from the side wall 10 and a leg 21 arranged essentially parallel to the side wall 10 and connected to the web 22. The rail 20 is designed integrally with the receiving device 8.

A displacement device 25 is displaceably mounted on the rail 20, the displacement device 25 according to one in cross section Fig. 4 the rail 20 has at least partially encompassing region 26. The area 26 is designed with two hook elements 27, 28, the upper hook element 27 corresponding to the leg 21 of the rail 20 in the view Fig. 4 from above and the lower hook element 28 according to the leg 21 in the view Fig. 4 encompasses at least partially from below. The hook elements 27, 28 are arranged relative to one another and relative to the rail 20 such that the hook elements 27, 28 and thus the displacement device 25 can be displaced relative to the rail 20.

In addition to the displacement device 25, a blocking device 30 with an area 31 is also displaceably mounted on the rail 20, the blocking device 30 having an upper hook element 32 and a lower hook element 33, comparable to the displacement device 25, each of which interacts with the leg 21 of FIG Rail 20 are executed. The hook elements 32, 33 of the blocking device 30 are at a greater distance from one another in the direction of extension ER of the leg 21 than the hook elements 27 and 28 of the displacement device 25, so that either the upper hook element 27 or the lower hook element 28 in the direction of extension ER of the T-shaped leg 21 can rest against the leg 21 and the blocking device 30 can thus be displaced perpendicular to the longitudinal direction LR of the rail 20 in the direction of extension ER of the leg 21 relative to the rail 20.

In the longitudinal direction LR of the rail 20, the displacement device 25 has two regions 35, 36, each interacting with the rail 20, the region 31 of the blocking device 30 interacting with the rail 20, as in particular in FIG Fig. 3 can be seen in more detail, is arranged in the longitudinal direction LR of the rail 20 between the first region 35 and the second region 36 of the displacement device 25.

In order to improve the guidance of the blocking device 30 in the direction of extension ER of the T-shaped leg 21 relative to the displacement device 25, the blocking device 25 has two here, for example in FIG Fig. 3 Grooves 38, 39, which run in more detail and extend in the direction of extension ER of the leg 21, in each of which a pin-shaped region 41 or 42 of the displacement device 25 is guided.

The displacement device 25 also has a coupling area 44 which is designed to cooperate with the fastening dome 17 of the housing 2. Likewise, the blocking device 30 has an essentially cylindrical coupling area 46, with which the blocking device 30 is arranged in an essentially hollow cylindrical connecting area 48 of the displacement device 25. Mutually facing wall areas of the coupling area 46 of the blocking device 30 and the coupling area 44 of the displacement device 25 can be shown in the illustration according to FIG Fig. 4 be tapered downwards. Both the coupling area 46 of the blocking device 30 and also the coupling area 44 and the connection area 48 of the displacement device 25 each have a through opening or through hole.

To fix the receiving device 5 on the housing 2, a fastening device 50, which is embodied here as a screw, is provided, which according to FIG Fig. 4 is guided from above through the through bores of the blocking device 30 and the displacement device 25 and is in engagement with the internal thread of the fastening dome 17. A head 51 of the screw 50 lies against a shoulder of the blocking device 30.

Like for example in Fig. 4 It can be seen in more detail that the receiving device 8 has, on the side wall 12 opposite the side wall 10, a further displacement mechanism 58 designed as a rail, which also has a further displacement device 59, a further blocking device 60 and a further fastening device 61 the dome 18 cooperates. With regard to the functioning and the interaction of these elements, reference is made to the above explanations regarding the corresponding elements on the other side of the receiving device 8.

The blocking device 30 is in a position in which the displacement device 25 can be displaced in the longitudinal direction LR relative to the receiving device 8. The lower hook element 33 lies essentially against the T-shaped leg 21 of the rail 20 and a lower surface of the coupling region 46 of the blocking device 30 in the extension direction ER is spaced apart from the fastening dome 17. The screw 50 is not yet completely screwed to the fastening dome 17.

In contrast to this, the screw 61 is completely screwed into the fastening dome 18. The upper hook element 32 of the blocking device 60 is in contact with the leg 21 of the rail 20 and clamped relative to it, so that a displacement of the displacement device 59 relative to the rail 20 and thus the receiving device 8 is prevented. The blocking device 60 lies here with the lower surface 47 of the coupling region 46 on the fastening dome 18.

When the receiving device 5 is connected to the housing 2 of the machine tool, the screws 50, 61 can for example first be brought into engagement with the respective fastening dome 17 or 18, the lower hook element 33 of the blocking devices 30 or 61 in contact with the respective one Rail 20 or 58 is. In this state, a position of the receiving device 8 with respect to the displacement device 25 or 59 and thus with respect to the fastening domes 17, 18 can be set to the desired extent. Subsequently, by further tightening the screws 50, 61, the blocking devices 30 and 60 can be wedged or clamped relative to the rails 20 and 58, so that the receiving device 8 is securely fixed relative to the fastening domes 17, 18.
