Technical Field

The present application describes a machining station for performing milling and deep drilling operations.

Background

At present, it should be noted that the current machining stations have a structural horizontal or vertical arrangement, with 5 axes-the axis along spaces X, Y and Z and the two axes of rotation of the machining station, for example on plane XY or XZ. In any case, the axis responsible for the drilling operation is called the z-axis, which represents a vertical structural arrangement to reorient the shaft according to this standard. It is noted in the machining stations of the prior art that their structural arrangement, in performing deep drilling tasks according to the drilling axis (Z axis), greatly limits their operability.

This is because current machining stations do not have axes dedicated to drilling operations and therefore have arrangements that do not allow the installation of the required support tools according to the specifications of the suppliers of deep drilling tools. This creates a limitation on the size (length) of the tool used in the gun drilling operation, limited to structural limitations of the path along the Z-axis, which in fact translates into limitations on the machining of the component. For example: when the machining centre has a path of 500mm along the Z axis and is located 700mm away from the machining station, only tools measuring 300mm can be fitted when the depth of the part to be worked is 400 mm. In other words, the depth of the bore hole may be limited to 200 mm.

General description of the invention

The present application describes a machining station with a particular structural arrangement, which can comprise a dedicated shaft (contrary to the existing stations) dedicated to deep drilling, referred to in the present document as the W axis. This facilitates the use of the drilling tool under ideal conditions of use without the size limitations that would constitute the limitations of the prior art.

The object of the present application is therefore to introduce a compact machining station having six axes and particularly arranged to perform deep drilling and milling operations. Performing said operations with said pressing implies mutual operations between the elements constituting said station along a plurality of displacement axes in three-dimensional space, as will be described in detail in the present description.

The object of the present application is also to introduce a machining station that is versatile and configurable to enable the above-described machining operations to be adapted to the machining characteristics programmed for the parts to be machined. It is a further object of the present application to introduce a machining station operable along multiple axes of three-dimensional space.

The above objects, features and advantages of the present application will be described later. According to one aspect of the present application, the object now described and/or other objects that may be evident are achieved by a compact machining station, which is built to guarantee the mutual operation between the elements that constitute it along a plurality of displacement axes of a three-dimensional space. For this purpose, machining stations were developed comprising an operating base on which the operating module and the placement module are placed.

Throughout the document, for the effect of the technical description, it is considered that the drilling axis W is always parallel to the Z axis, which means that the axis is reoriented based on its vertical or horizontal direction. For this reason, the description of the technical features constituting the machining station will promote a clear understanding of the concepts developed herein, considering the horizontal layout of said stations, i.e. the drilling axis (W axis) is parallel to the Z axis according to the horizontal direction. However, it is believed that the technical concept described herein (which enables the development of 6-axis machining stations) will be easily converted to embodiments of said stations having a vertical layout, wherein the drilling axis W is parallel to the Z-axis according to the vertical direction.

According to an aspect of the application, the operation module comprises an operation table mounted on a rotation block mounted on the operation base. The rotation block is used to provide the console with a 360 ° rotation movement in the plane XZ and a 135 ° rotation movement in the plane YZ. In addition to the rotary motion exerted on the rotary block, the rotary block has a linear motion along the Z-axis by being fitted on at least one displacement guide mounted on the operating base. The rotational movement of the console and the linear movement of the manipulator block are driven by mechanical systems.

According to another aspect of the application, the machining station comprises a support structure arranged on the operating base and separating the operating module and the arranging module. The separation is achieved by connecting the partitions belonging to the arrangement modules to the support structure, so as to physically separate between said modules. The diaphragm has freedom of linear movement towards the X and Y axes and these movements are driven by a mechanical system.

Moreover, according to an aspect of the present application, the machining station developed additionally comprises an arrangement module. In addition to the spacer, the placement module also comprises a drill arm which is connected at one of its ends to a placement window designed to facilitate the connection of said arm to the spacer in order to perform a machining action in the operating module. The drilling boom is mounted on the operating base by means of a mechanical support that mounts on its body at least one vertical displacement guide on which the drilling boom is arranged so as to have a linear movement towards the axis Y. The mechanical support is mounted on at least one displacement guide on an operating base which also imparts linear movement of the drilling boom along the X-axis. The linear movement of the boom and the mechanical support is driven by a mechanical system. The placement window and the respective drill arm are thus moved in unison with the partition, which enables two separate spaces to be created-an operating space and a placement space-to prevent liquid, debris or dust formed in the operating module from passing to the placement module.

The drill boom is arranged to perform milling or deep drilling operations and comprises a drive unit, hereinafter referred to as a column (tree), which moves inside the boom along a W-axis parallel to the Z-axis. The drill boom further comprises an arrangement window enabling the column to perform milling and drilling work in the operation module. The drill boom thus has a connection mechanism enabling the mounting of at least one drill bit flange on the arrangement window and the mounting of a corresponding tool support comprising a damper, which tool support assists the drilling tool in performing deep drilling operations. The fitting of the support forces the post to move to a rearmost position-opposite the placement window. In contrast, for milling operations, no support is mounted on the drilling boom, resulting in the column being moved to the forwardmost position, the window being arranged immediately adjacent, so that the milling tool is directly connected to the column (either manually by the operator or automatically by operation of an external robotic system). To this end, the structure has an automatically opening door that enables the robotic system to access the interior of the station.

The drilling boom has a door whose purpose, besides enabling the operator to change the drilling tool, is to prevent the passage of liquid (oil or cutting emulsion) to the station's layout module. In order to prevent their accumulation inside the drilling booms, the configuration of the structural body of the drilling base is slightly inclined so that the liquid returns to the operating module through the discharge outlet mounted on the placement window of the drilling booms, so that they can be reused. The machining station therefore also comprises a filtering module, aimed at cleaning and filtering the oil/cutting emulsion used during the machining process, so as to ensure their re-use.

In connection with the control of milling or deep drilling operations, the entire operation of the mechanical processing station developed is performed by a central control unit, by the operation of the mechanical system and the corresponding pneumatic, hydraulic and electric mechanisms, since the movement of all its elements in three-dimensional space is programmed.

Detailed Description

Some embodiments are described in more detail below with reference to the drawings, although they are not intended to limit the scope of the present application.

In one embodiment of the machining station (1), the machining station (1) comprises an operating base (2) on which the operating module (3) and the placement module (10) are mounted. The two modules are physically separated by a partition (8) connected to a support structure (7), which support structure (7) is arranged on the operating base (2).

In one embodiment of the machining station (1), the operating module (3) comprises an operating table (5) mounted on a rotating block (4), the rotating block (4) being mounted on an operating base (2). The rotary block (4) is used to provide the console (5) with a 360 ° rotary motion in the plane XZ and a 135 ° rotary motion in the plane YZ. In addition to the rotary motion applied to the rotary block (4), the rotary block (4) has a linear motion along the Z-axis by fitting the rotary block (4) on two displacement guides mounted on the operation base (2). The rotary motion of the console (5) and the linear motion of the rotary block (4) are driven by a mechanical system.

In a particular embodiment of the machining station (1), the placement module (10) comprises a bulkhead (8) and a drilling boom (11), the drilling boom (11) being connected at one of its ends with a placement window (9), the placement window (9) being designed to facilitate the connection of said boom (11) with the bulkhead (8) in order to perform a machining action in the operating module (3). The drilling boom (11) is connected to the operating base (2) by means of a mechanical support (15), which mechanical support (15) mounts on its body two vertical displacement guides on which the drilling boom (11) is arranged so as to have a linear movement towards the Y axis. The mechanical support (15) is mounted on a displacement guide on the operating base (2), which also imparts a linear movement to the drilling boom (11) along the X-axis. The linear movement of the boom (11) and the mechanical support (15) is driven by a mechanical system.

In one embodiment, the drilling boom (11) is arranged to perform milling or gun drilling operations, the drilling boom (11) always comprising a drive unit, hereinafter referred to as a column (12), which moves inside said boom (11) along a W-axis parallel to the Z-axis. The drilling boom (11) further comprises an arrangement window (9), which arrangement window (9) enables the column (12) to perform milling and drilling work. Thus, in the case of deep drilling tasks, the drill boom (11) has a connection mechanism which enables the drill flange (16) to be mounted on the arrangement window (9). The fitting of the corresponding support (17) of the gun-drilling tool (18) forces the column (12) to move to its rearmost position — opposite the placement window (9). In contrast, for milling operations, no support is mounted on the drilling boom (11), causing the column (12) to move to its forwardmost position, placing the window (9) in close proximity, so that the milling tool is directly connected to the column (12) (either manually by the operator or automatically by operation of an external robotic system (6)). For this purpose, the structure has an automatically opening door that enables the robotic system (6) to access the interior of the station (1).

In a special embodiment, the drilling boom (11) has a door (13), the purpose of which door (13) is to prevent liquid (oil or cutting emulsion) from passing to the station's placement module (10) in addition to enabling the operator to change the drilling tool (18). In order to prevent them from building up inside the drilling boom (11), the structure of the body of the drilling base (19) is slightly inclined so that the liquid returns to the operating module (3) through the discharge outlet (14) mounted on the arrangement window (9) of the drilling boom (11), so that they can be reused.

In a particular embodiment of the machining station (1), the machining station (1) additionally comprises a filter module, with the aim of cleaning and filtering the oil/cutting emulsions used in the machining, so as to ensure their reuse.

Of course, the present description is in no way limited to the embodiments presented in this document, and a person of ordinary skill in the art will be able to conceive many possibilities to modify them without departing from the general idea as defined in the claims. The above-described preferred embodiments can obviously be combined with each other. Preferred embodiments are additionally defined by the following claims.
