Abstract

A device for holding a plurality of tools or drives for attachment to a movement machine, characterized in that the device itself has one or more other means in the form of drives and / or moving means and axes, which allow the position and location of Device itself and their individual, attached thereto devices relative to the attachment point of the device itself to the machine to move.

Description

problem

For the production of objects and components different materials and methods for the production can be used. These methods are performed by tools that are positioned and guided by a motion machine. In the current state of the art, the tool is removed from the motion machine after processing and the necessary tool for the follow-up process is installed in the motion machine to then perform a corresponding processing. In some production processes, during which the individual processes have to be changed over and over again, long change times result, which reduce the effectiveness of the overall processing process.

In the field of additive manufacturing, arc surfacing is used to produce rather coarse structures, but with a high deposition rate. The final contour achieved is rough and characterized by the appearance of individual weld beads. In addition, in the method, a very high energy input, the position by layer to a heat treatment of the top layer adjacent areas and thus to influence the microstructure and the resulting properties. To achieve a finished component with the appropriate surface and the required material properties, it is necessary to perform optimizing processes between the individual layers, which can positively influence both the dimensional accuracy and the performance characteristics of the finished component.

These accompanying processes are:

1. 1. Milling the surface to comply with the required dimensions.
2. 2. Clean the topmost crawler to keep oxides and contaminants out of the molten bath
3. 3. Mechanical reshaping of the upper seam areas to produce microstructure disturbances as growth nuclei for the subsequent seam heat treatment with possible grain remodeling.

In addition, of course, comes the actual build-up welding process, which causes the actual material structure.

Similar requirements are necessary in the application of other additive processes, even if the individual tools and the material differ.

All processes are sequential in time and are performed by different devices / tools that are available in a change magazine for tool change in conventional machines.

For the movement of the tools different kinematics are used; Any type of kinematics can be used for the invention.

The structure and the operation of the invention is shown by way of example on a Cartesian machine with 3 axes, but is transferable to any, even non-Cartesian machine.

invention

To increase the efficiency, it is helpful not to change the individual tools, which are needed in quick succession, but to attach to a device on which they are arranged side by side and can be brought into their working position only by a short shift, without the long distances covered and long-lasting change processes must be carried out.

At the actual tool holder on which otherwise, for example, a drive with changing device for different cutters sits, a device is attached, which is parallel to the plane parallel shift or rotation of a plate or a beam, to which several different tools such as welding torch ( 5 ), Milling spindle with milling cutter ( 6 ), Drive with wire brush ( 7 ) and possibly other devices or sensors, for example, are fixed for the deformation of the surface, these different tools can bring by short displacement paths in interaction with the surface without a tool magazine must be approached.

Variants:

Straight bar (Figures 1, 2 and 3A)

Straight bar ( 9 ), rigidly mounted on the Z axis, parallel to the XY plane (1, 2) with individually juxtaposed functional units / tools / processes, in which the entire beam is moved by shifting all the axes until the corresponding process engages with the Workpiece is. In order to avoid collisions, the non-engaged tools are lifted by a Z-direction stroke or removed from the processing area by a rotational movement about the X or Y axis.

In a second variant of the straight beam this is not rigidly connected to the Z-axis but slidably arranged in the Y direction, that the respective process used can be arranged in direct alignment with the course of the Z-axis. The non-engaged tools are also withdrawn from the work area by the above-mentioned possible movements in order to avoid collisions.

Circular arrangement (FIG. 3B)

The different processes / tools ( 5 . 6 . 7 ) are mounted on a Z-axis rotatable plate ( 10 ), which is mounted either rigid or rotatable and thus holds the individual tools. Again, the non-engaged tools are removed by a pivotal or linear movement of the work area to avoid collisions.

Advantage of the system:

No complicated movements for the purpose of tool change. Through small movements, the individual tools can be brought into position to the workpiece and perform the necessary processes to complete the geometry and optimize the material properties.

In a suitable embodiment of the invention, other tools and sensors for quality assurance and process control can be adapted in the same way.
