Definitions
- the invention relates to a machine tool cocoon for a machine tool and a method for operating a machine tool.
- Machine tools are machines for manufacturing workpieces with tools.
- the movement between tool and workpiece is specified by the machine tool during machining.
- the material of the workpiece is often machined one after the other with several tools in order to manufacture a component from it. Machining processes in machine tools are typically milling, turning, but eroding and pressing can also be carried out automatically in machine tools.
- the tool clamped in the machine tool is therefore preferably exchangeable, with different tools, such as milling cutters, drills, indexable insert tools, being used in the respective machining process used.
- tool changing devices with tool storage and / or tool magazines are used, in which the tools used in the respective machining steps can be exchanged and changed automatically.
- a supply of different tools is provided in a supply area connected to the machine tool, the tool storage or tool magazine, and is automatically brought into the processing unit of the machine tool before the respective processing step.
- the tool is typically held in a work spindle or main spindle.
- the main spindle is also known as the milling spindle when the tool is a milling cutter.
- the main spindle is the tool interface.
- the machine tool which is also referred to as a machining center (BAZ), including the machining steps and the tool changing device, is typically controlled by means of a sequence control.
- the main task of the sequential control system is to guide the movement of the tool along any shape during the machining of the workpiece. Monitoring the cutting force of the tool and the tool change can also be part of the task of the sequence control.
- the workpiece to be machined is arranged, for example, in an area below the tool.
- workpiece clamping systems such as zero clamping systems in particular, are widely used in order to ensure an exact, reproducible positioning of a workpiece clamping means of the workpiece.
- the workpiece is placed manually in the machining position.
- the machine tool is stopped and the machined workpiece, usually the finished component, is removed from the workpiece clamping system and the new workpiece to be machined is arranged in it.
- the manual clamping and removal of workpieces is time-consuming, on the one hand because manual work is necessary, on the other hand because the machine tool has to be stopped. To do this, it is necessary to bring the tool spindle into a safe position so that a machine operator can open the door.
- a tool changing device for a machine tool is known from DE 202006 015 240 U1.
- the tool changing device describes a device that enables the tools of a machine tool to be changed automatically.
- EP 3 354 400 A1 discloses a machine tool for processing dental implants in the dental field.
- Workpieces can be stored in holders provided in a workpiece magazine.
- DE 100 34 973 A1 discloses a machine tool with a tool changer, wherein the workpiece can be fastened to a spindle and rotated with it in order to be machined by a stationary tool.
- the object is achieved by a machine tool cocoon according to claim 1 for receiving a workpiece.
- the machine tool cocoon has a floor element on which the workpiece can be arranged, the floor element having at least one receiving device for receiving and fixing a workpiece and wherein the machine tool cocoon can be arranged on a tool position of a machine tool.
- the machine tool cocoon has a support device detachably connected to the base element, the machine tool cocoon being able to be positioned on a tool position of a tool change system by means of the support device.
- the machine tool cocoon is typically used in a machine tool with a tool change system.
- the machine tool cocoon can be used in a tool change system of the machine tool.
- the machine tool can have a tool changing device or a tool changing system and a machining unit for machining the workpiece.
- the tool changing device typically has a tool memory with tool positions for arranging tools.
- the workpiece to be machined is typically arranged in the machine tool cocoon before the machine tool cocoon is inserted into the tool store or the tool magazine.
- the tool to be used in each case is or the tools are typically brought from the tool store into a work spindle or the main spindle of the machining unit of the machine tool during operation of the machine tool.
- This can be done in that the processing unit moves directly from the processing position to the tool position of the tool storage or tool magazine, picks up the tool by means of a clamping tool, preferably a tool cone, and moves it back into the processing position.
- the tool change system can also have a transfer system, which is used to move the tool out of the tool Position of the tool store is used in the work spindle.
- the tools can be moved from the respective tool position of the tool changing system into the work spindle, which is used for the tool holder, of the machine tool.
- the spindle can be referred to as the main spindle, work spindle or tool spindle.
- the invention makes use of the knowledge that, by means of such a tool memory, not only tools can be stored, transported and transferred to a tool spindle, but also other elements, such as workpieces in particular, if these are appropriately prepared.
- the machine tool cocoon according to the invention takes on this task within the scope of the invention. It is used to pick up a workpiece and thus make it available and storable in a tool memory.
- the machine tool cocoon also serves to transfer the workpiece from the tool store into the workpiece clamping system of the machining unit of the machine tool. As is also common with tools, the transfer can take place directly with the aid of the tool spindle or with the aid of a transfer system.
- the tool storage of the tool changing system or the tool changing device typically has 20 or more positions that can be equipped with tools. In most cases, not all tool positions are required for an automated machining process, so that free tool positions are available.
- the machine tool cocoon can be arranged at one or more of the available tool positions. One, two or more machine tool cocoons can be arranged at free tool positions. A machine tool cocoon is provided for each tool position. The number of machine tool cocoons used can preferably be freely selected, depending on how many workpieces are to be machined in an automated machine run.
- the machine tool cocoon with the workpiece can be moved from the tool position of the tool store into a workpiece clamping system, preferably a zero point clamping system, of the machine tool.
- the zero point clamping system is preferably a sub-element of the machine tool, in particular of the machining unit of the machine tool.
- the zero point clamping system is used to position the workpiece in the machining position.
- the machine tool cocoon can be moved from the tool position in the tool storage to the machining position by means of the identically constructed clamping tool, which is also used to transfer the tools.
- both the tool can be brought from the tool storage device into the tool spindle and thus exchanged, and the work piece can be exchanged with the aid of the machine tool cocoon.
- the machine tool cocoon together with the workpiece to be machined is moved from the tool store into the machining position, for example into the zero-point clamping system.
- Machined workpieces can be moved from the machining position into the tool store using the machine tool cocoon.

- the machine tool is then usually stopped and the workpiece to be machined is changed.
- the machine tool is then typically restarted and runs through the machining program again.
- both an automated tool change and an automated workpiece change can advantageously take place by using the machine tool cocoon. It is advantageous here that, in particular, no conversion of the tool changing system is necessary, since the tool store is also used as a workpiece store. There is also no need to attach to the tool change system in order to implement additional transfer devices for a workpiece change from other storage positions than the tool storage position during an automatic machining process of the machine tool.
- a machine operator can equip the machine tool cocoon outside of the machine tool with a workpiece to be machined and insert it into the tool store. The machine tool does not have to be stopped for this.
- the corresponding machine tool cocoon can be removed from the tool storage and positioned in the machining unit by means of the workpiece clamping system.
- the workpiece can then be processed and at the end of the machining, the workpiece can then be brought again by means of the machine tool cocoon from the machining unit to the tool storage, from which the machine operator can then remove the machine tool cocoon together with the machined workpiece.
- the machine operator can equip one or more additional machine tool cocoons or carry out other activities such as checking, reworking, deburring, etc. This can save considerable working time.
- the machine tool cocoon With the machine tool cocoon, a machine-independent device is created with which a change of workpieces is made much easier. No special setup or preparation of the machine tool is required. Rather, the machine tool cocoon preferably only uses devices of the machine tool that are provided as standard. The machine tool cocoon can be used by a user as required; it is not necessary to equip or convert the machine tool except for the provision of appropriate programming.
- the machine tool cocoon can be automatically reclamped. This means that while conventional clamping of workpieces on a zero point clamping system only allows four-axis machining, more extensive multi-axis machining can also be implemented with the aid of the machine tool cocoon.
- the machine tool cocoon can first be removed from the tool store by means of the tool lockers and positioned on the zero point clamping system. Then, as already described above, the support device is detached from the base element and preferably positioned in the tool store. The workpiece is then processed. The support device can now be positioned on the base element again by means of the tool spindle and locked to it.
- the machine tool cocoon can thus be repositioned, for example rotated, by means of the spindle, preferably in a range of> 0 ° and ⁇ 360 °, for example 90 ° or even less.
