Description

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

Receiving devices are well known from practice, which have receiving devices designed to receive electronic components of machine tools, the electronic components being intended to be protected by the receiving devices from dust and particles, for example. An example is from US6964545B1 known. 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 receiving device is designed for a specific housing of a machine tool, so that, for example, different receiving devices are to be provided for different machine tools.

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

This object is achieved with a receiving device for an electronic device, in particular of a machine tool, with a receiving device designed to receive the electronic device, in particular in the form of a cup, and with a fastening device for connecting the receiving 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, wherein a blocking device or positioning device which interacts with the displacement mechanism and is coupled to the displacement device is provided, wherein the displacement device can be connected to the housing of the machine tool by means of the fastening device, and wherein the Blocking device in the middle of the fastening device when it is connected to the housing of the machine tool ls the fastening device can be fixed to the displacement mechanism and as a result 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 space and can be used in different machine tools depending on the available space. In particular, in a work step with the fastening of the receiving device, for example to a fastening dome of the housing, a position of the receiving device relative to the displacement device can be fixed by the fastening device, for example by clamping the blocking device on the displacement mechanism. As a result, both the attachment of the receiving device to the housing and the fixing of a position of the receiving device relative to the displacement device can be achieved in a structurally simple manner in a single work 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. As an alternative to this, the displacement mechanism can also be designed as a link, for example.

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

The displacement device and the blocking device preferably each have an area that encompasses the rail, with both the displacement device and the blocking device preferably being designed for this purpose 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 between the upper hook element and the lower hook element in the longitudinal direction of the fastening device is preferably greater in the blocking device than in the displacement device. When the blocking device is in a state that allows the receiving device to be displaced relative to the displacement device, an upper hook element of the blocking device in particular is at a distance from the rail or has play relative to the rail, so that the receiving device can be displaced relative to the displacement device in a structurally simple manner and the blocking device is enabled.

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

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

The blocking device is preferably mounted with a region within a region of the displacement device, with a through-opening for the fastening device being provided in each of these regions of the blocking device and the displacement device. As a result, when the receiving device is fixed to the housing, the blocking device can be fixed or clamped relative to the rail in a structurally simple manner, which also causes the displacement device to be displaced relative to the displacement mechanism. The through-openings can be designed as conically tapering 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 configuration, 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 essentially over the entire length of the side wall of the receiving device in order to achieve a large displacement possibility of the receiving device relative to the displacement device.

A secure 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 that 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 designed in particular in the form of a cup and preferably forms an interior space for receiving at least some of the electronic components. The receiving device, which is designed in particular in one piece or in one piece, has in particular a rectangular cross section, but can also have cross sections of a different design.

An assembly consisting of a housing of a machine tool and such a receiving device is also proposed, the housing of the machine tool having at least one screw-on dome or fastening dome to which the receiving 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 receiving device can be displaced in relation to the displacement device, so that the receiving device can be arranged flexibly depending on the installation space available and can be used with different machine tools. In particular, in a work step with the fastening of the receiving device, for example to a fastening dome of the housing, a position of the receiving device relative to the displacement device can be fixed by the fastening device, for example by clamping the blocking device on the displacement mechanism. As a result, both the attachment of the receiving device to the housing and the fixing of a position of the receiving device relative to the displacement device can be achieved in a structurally simple manner in a single work step.

Examples:

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

The receiving device 8 is configured here with a base body 9 that is essentially plate-shaped and, in the present case, rectangular, with four side walls 10, 11, 12, 13 adjoining an edge area of the base body 9 perpendicularly to the base body 9, which here are integral with the base body 9 are. The receiving device 8 is cup-shaped here, with the base body 9 and the side walls 10, 11, 12, 13 delimiting an interior space 15 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 attachment domes 17, 18 or screw-on domes, each of which is designed with an internal thread.

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

A displacement device 25 is slidably mounted on the rail 20, the displacement device 25 having a cross section according to FIG 4 has a region 26 which at least partially encompasses the rail 20 . The area 26 is designed with two hook elements 27, 28, the upper hook element 27 the leg 21 of the rail 20 in the view according to FIG 4 from above and the lower hook element 28 the leg 21 in the view according to 4 at least partially embraces from below. The hook elements 27 , 28 are arranged relative to one another and relative to the rail 20 in such a way 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 a region 31 is also slidably mounted on the rail 20, with the blocking device 30 having, comparable to the displacement device 25, an upper hook element 32 and a lower hook element 33, each of which is designed to interact with the leg 21 of the Rail 20 are running. 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 perpendicularly 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 that interact with the rail 20, with the region 31 of the blocking device 30 that interacts with the rail 20, as in particular in 3 can be seen in more detail, is arranged in the longitudinal direction LR of the rail 20 between the first area 35 and the second area 36 of the displacement device 25 .

In order to improve a guidance of the blocking device 30 in the direction of extension ER of the T-shaped leg 21 in relation to the displacement device 25, the blocking device 25 here has two, for example in 3 grooves 38, 39, which can be seen in more detail and run in the extension direction ER of the leg 21, in each of which a pin-shaped area 41 or 42 of the displacement device 25 is guided.

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

To fix the receiving device 5 to the housing 2, a fastening device 50 designed here as a screw is provided, which is shown in accordance with 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 rests against a shoulder of the blocking device 30 .

As for example in 4 As can be seen in more detail, 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 is provided with a further displacement device 59, a further blocking device 60 and a further fastening device 61 the fastening dome 18 cooperates. With regard to the functioning and the interaction of these elements, reference is made to the above explanations for 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 relative to the receiving device 8 in the longitudinal direction LR. The lower hook element 33 rests essentially on 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 at a distance 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 here in contact with the leg 21 of the rail 20 and clamped relative to it, so that displacement of the displacement device 59 relative to the rail 20 and thus the receiving device 8 is prevented. The blocking device 60 bears against the fastening dome 18 with the lower surface 47 of the coupling area 46 .

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