Description

The invention relates to devices for machining the ends range of workpieces with at least one rotating work stuff and stationary workpiece, especially of large and / or Long tubes.

Machining of radially fixed workpieces with turning the tools are known from several solutions.

Processing heads are inter alia in DE 29 52 752 (rotary head, especially facing head) and DE 34 40 398 (rotating Machining head). A movement of the tools ge compared to the workpiece is assumed or not closer wrote.

The movement of the tools takes place in DE 32 37 587 (before direction for the production of threaded connections on large pipes) via a rotating and slidably arranged dop drive rod toothed on the side. Forehead attached to it gears, which are simultaneously arranged in tool stands Gripping racks serve to move the tool trestles. This means that the tool stands can only be moved at the same time and independent movement is not possible. The tools move to the workpiece in DE 33 41 479 (Facing device), one device has a turret with several tools and the against can be moved over the workpiece via a switch clutch. The movements of both the work wave and the Tool components are directly coupled to one another, so that an independent movement of the tool components is not possible is.  

The invention specified in claim 1 is the problem underlying, in particular the end areas of workpieces to process large tubes or long tubes so that flat surfaces, phases, copied surfaces and / or threads stand.

This problem is with those listed in claim 1 Features resolved.

The devices for machining the end portion of the factory pieces with at least one rotating tool and a stationary one Workpieces are characterized in particular by the fact that Tool can be used at any time with the tool carrier rotating is removable. When arranging several tools on the factory Witness carriers are both independent of each other as well can be moved independently of the workpiece. simultaneously can the movement of the tool against the workpiece ge be stopped. The tools for this are on or on components attached. The components are e.g. B. executed as a sled. Another major advantage is that with the Component including a drive mechanism for a tool the tool is connectable. This moves the tool so that manufacturing processes based on them can be used can. Such methods are e.g. B. milling, grinding and Sawing process, which is achieved in particular through the small distinguishable chip geometries. For shredding the Chips necessary constructions in the form of z. B. Chipbreaker are avoided, so that favorable economic aspects are given are.

Another advantage is that the movements are both of the tool holder as well as the tool (s) regardless of each other. A switching operation or an interruption editing is not necessary, so continuous  The workpiece is machined.

The movements can be synchronized. The setting and control and / or regulation of the processing technology is significantly simplified. Furthermore, it will show called processing errors avoided.

The device is further characterized by its modular Structure made by a frame with a drive for the Tool holder and the tool holder with a difference union number z. B. against straight guides for several components ben is.

Through an annular tool holder, a free space in the frame and a correspondingly designed drive or a drive arranged outside the tool holder the workpiece before, during or after machining in the Device are inserted so that long machining Stretch can be achieved, or performed by the device become. This means that a wide variety of applications are possible give. Among other things, there is only one direction of movement for that Workpiece necessary, so simple handling techniques for the transport of the workpiece before or after its processing are necessary. At the same time is a continuously working Production line can be realized without the workpiece being loaded working of the ends must be turned. The space requirement redu adorns itself to a minimum. This is special particularly important for very long workpieces.

With the use of a circular tool holder the tools can be moved to the center. So that the end areas can both in their diameter small workpieces as well as the interior of large tubular ones Workpieces are processed.

Another advantage is that instead of a plant sensors can also be coupled with the component. A sensor is to be understood as a converter that transmits a sig nal records with a signal carrier and with another Sig nalträger preferably emits an electrical signal carrier.  

To do this, the output of the sensor is programmable Control and / or regulating device connected. Usually are the sensor, detectors or sensors. Feelers change theirs Properties e.g. B. the electrical resistance in a loading influence z. B. by the action of mechanical forces.

Advantageous embodiments of the invention are in the patent claims 2 to 11 specified.

So that both the outer surface and the inner surface of the End area of the workpiece are processed. It can be so be done successively as well as simultaneously. The second  Tool carrier is advantageously designed such that whose tools in the end area of the interior of the work piece can be moved. Due to the ring structure of the first tool carrier, the frame and the electric motor as a drive for the first tool carrier, the workpiece can be in this trained cavity are retracted. The second Tool carrier can also be out of the device be moved so that a wide area of the inner surface of the Tool can be edited.

A device with two parallel and circular tool carriers, with an annular Electric motor is in between and with these tool carriers is coupled directly or via gear, according to the further development extension of claim 4 is advantageously for processing device of the two ends of particularly short workpieces suitable. These are e.g. B. detachable pipe connectors in the form of Threaded sockets. This makes the production very economical like workpieces available. The workpiece is there advantageously with a clamping device movable in Cavity so that both ends at the same time or after a cure zen travel in succession without rotating the workpiece can be worked. At the same time, the essential is part that only one drive for the tool carrier necessary is. This is a very economical production of especially short tubular workpieces with threads as Given sleeves.

A clamping device coupled with a translatory drive direction for the workpiece after further training of the patent Proposition 5 ensures the positioning of the workpiece in the machining area of the tools and leads to another cause a wide inner and / or outer surface of the ends area of the workpiece can be machined. simultaneously  becomes a central position of the work by the clamping device guaranteed to the tool carrier.

A connection of the coupled to the second tool carrier Drive with a translatory drive after the next education of claim 6 leads to an independent Be movement of the second tool carrier compared to the first plant tool carrier and the workpiece. A wide inner surface of the The workpiece can thus be machined.

Electric motors for the drive mechanisms of the tools the further development of claim 7 convert easily transportable energy in a mechanical movement, being this movement slightly affected by a corresponding control is flowable. With the arrangement of the rotor of the electric motor parallel or perpendicular to the axis of symmetry of the workpiece allows the use of tools, their processing surface is an end face or a peripheral surface. Thereby a variety of tools can be used.

Inexpensive tools for machining the workpiece are in the training of claim 8 listed. These are among other things, a turning tool for surface processing or a flat thread chaser for inserting a thread as non-driven tool and a round thread chaser, Hob cutters, thread whirling tools for insertion of a thread, saw blade for cutting, rotary milling cutter for Surface treatment, a brush for deburring or a Grinding wheel for cutting or for surface processing as powered tool.

1st embodiment

A device 1 for machining the end region of work pieces 2 with at least one rotating tool 3 and standing workpiece 2 in a first embodiment consists essentially of a driven and circular tool holder 4 , which is either directly with a moving part of a drive or is connected via a gearbox, with the other hand the drive and / or the gearbox being coupled to a frame 5 .

The direct drive is a brushless ring-shaped electric motor 6 whose rotor 8 ger 4 with the ring-shaped Werkzeugträ and whose stator 7 is fixed to a frame 5 . Between the frame 5 and the annular tool holder 4 is a rolling bearing 9 for supporting the circular tool carrier. 4 The annular electric motor 6 as a direct drive is a synchronous motor, 8 magnets are arranged on the rotor and a three-phase winding is located in the stator 7 . A magnetic rotating field is generated in this. A frequency converter is used to control the ring-shaped electric motor 6 . Fig. 1 shows one of the like device 1 with the annular electric motor 6 and the annular tool holder 4 in a schematic sectional view.

Through the annular tool holder 4 and the ringför shaped electric motor 6 , a cavity 10 is present in which the workpiece 2 or at least the end region of the workpiece 2 can be moved. A wide end region of the workpiece 2 , which can be moved relative to the device 1, can thus be machined.

The annular tool carrier 4 has a plurality of Gerad leadership 11 in the form of

• - Flat guides with wrap-around strips to prevent the carriage,
• - dovetail guides,
• - Prismatic guides z. B. in roof and V shape,
• - Combinations, that is, different guides on each side of the straight guide 11 , from or
• - cylindrical guides on,

that radiate away from the center. The angles between straight lines

11

are 180 ° (2 guides), 120 ° (3 guides), 90 ° (4 guides) or 60 ° (6 guides). In the

FIG.

2 is an annular tool carrier

4

with three linear guides

11

shown in principle in a top view. The straight guides

11

are either with sliding guides a hydrodynamic, hydrostatic or aerostatic Lubrication or as roller guides. As rolling elements balls, cylindrical rollers or needles are used. A Circulation elements with feedback are a special variant the rolling elements, arranged in one, two or four rows are. Another option is ball guides with a 2- or 4-point contact of the spherical rolling elements between a circulation shoe and a guide bar. At least in each case a component

12

is with a straight line

11

coupled. each component

12

is equipped with a drive as a linear drive.  

On the one hand, this is an electric motor that causes a translatory movement, e.g. B. via a threaded spindle / nut system or rack / gear system, the rotational movement of the electric motor is converted into a translational movement. Another variant are roller screw drives. These are particularly characterized by their high rigidity and high axial load capacity. The roller screw drive basically consists of a threaded spindle and a threaded nut. In the threaded nut, axially parallel thread rolls are arranged. If the threaded spindle rotates, the thread rollers rotate around the threaded spindle like a planet without axial displacement. Sprockets guide the thread rolls ra dial. The electric motor is advantageously coupled to a rotary encoder, so that the position of the component 12 can be detected. The electric motor can also be an electric stepper motor, which consists of several stators and performs angular steps when the fields are controlled accordingly, so that such a drive is both a motor and a measuring device. On the other hand, there are continuously operating linear motors (direct current linear motors, electrodynamic linear motors, walking field linear motors) or linear step motors (electromagnetic linear stepper motors, piezo motors, magnetostrictive linear step motors).

Component 12 also has a holding structure for a tool 3 . The holding structure is designed so that the tool 3 can be releasably attached. The tool 3 is a chisel for producing a cone or for parting off the cross-sectional area of the workpiece 2 or a tool 3 for introducing a thread in the form of a chisel or flat screwdriver, so that an end region of the workpiece 2 is machined. In Fig. 8, a basic presen- tation of an arrangement for internal machining of a work piece 2 is shown as a section, with a flat-thread chaser is shown in principle as tool 3 .

A memory-programmed or numerical control with a microcomputer system, which is located on the ring-shaped tool carrier 4 , takes over the control of the movements and the positioning of the components 12 . This is done using software that is implemented in the microcomputer system before processing. A memory is either written before the processing or an external memory is detachably coupled to the microcomputer system. This memory remains with the microcomputer system during processing. The memory is advantageously a data memory in card form, which can be connected to the microcomputer system via contacts. The map contains z. B. an EPROM, EEPROM, mask-programmed ROM, NOVRAM or eDRAM.

The microcomputer system is either a central system or a multiprocessor system. In the first case, the electric motors of the components 12 and position-determining devices in the form of z. B. the encoders coupled to the electric motors connected to the central system. In the second case, each electric motor of the components 12 with a microcomputer system is advantageously with a position-determining device in the form of z. B. the encoder coupled to the electric motor for each component. These microcomputer systems are either di rectly or connected to one another as a control center via a further microcomputer system.

A sliding contact system 13 , which is shown in principle in FIG. 1, is located between the moving circular tool carrier 4 and a fixed component of the frame 5 . This serves to transmit electrical energy from an electrical energy source to the moving circular tool holder 4 . The basis is at least one spring that is moved on an annular conductor track. Conversely, the conductor track can also move in relation to the spring. Both the spring and the conductor track consist of an electrically conductive material with high wear resistance. The number of springs depends on the electrical conditions for the power supply.

In a first variant, at least one spring and one conductor track are required per conductor of the energy network. The conductor tracks are arranged parallel to one another. In particular, the single or three-phase network with an alternating voltage is used as the energy network. Accordingly, at least one conductor track and at least one spring are used for each phase and the neutral conductor. This provides an electrical power supply for the drives and the microcomputer system on the tool carrier. The voltages for the individual electric motors and the microcomputer system are generated from the AC voltage of the respective network via power supplies on the annular tool holder 4 .

In a second variant, the power supplies are located outside the circular tool carrier 4 and are stationary. The individual voltages for the electric motors and the microcomputer system are transmitted to the annular tool holder 4 by means of the sliding contact system 13 . This allows the power supplies to be cooled more easily and in a controlled manner. The device is started either optically via light beams or by means of electromagnetic waves between a transmitter on the frame 5 and a receiver on the annular tool holder 4 without contact.

The workpiece 2 is located on a clamping device, which positions it in the axis of symmetry of the annular tool carrier 4 . Furthermore, the clamping device can be moved relative to the annular tool carrier 4 via a translating drive. The Spannvor direction is known to be realized and not shown in Fig. 1.

In one embodiment of the first exemplary embodiment, a circular tool carrier 4 can be provided with a drive. In Fig. 3, a circular tool carrier 4 is shown in principle in a plan view. Thus, two components 12 can be arranged per straight guide 11 , so that the outer and inner surfaces (shown in FIG. 8) of a tubular workpiece 2 can be machined.

The second tool carrier 4 b is designed as an annular or circular tool carrier 4 b accordingly to the first embodiment. The external dimensions of the second tool holder 4 b are smaller in cross section than the cross section of the cavity 10 formed from the first annular tool holder 4 a and its ring-shaped electric motor 6 .

The second tool carrier 4 b is, on the one hand, coupled to the rotor 14 of a further electric motor 15 directly or via a gear such that the second tool carrier 4 b carries out rotary movements. The second tool carrier 4 b, its components 12 and the tools 3 coupled to it are designed such that the inner surface (shown in FIG. 8) and / or the cross-sectional surface of the end region of the workpiece 2 can be machined. For this purpose, the second tool carrier 4 b is supported against the frame 5 by a further roller bearing 9 b. The processing of the outer surface of the end region of the workpiece 2 takes place via the tools 3 of the first annular tool carrier 4 a according to the first embodiment. The stator of the further electric motor 15 is coupled to the frame 5 .

In a first variant, the further electric motor 15 for the second tool carrier 4 b is firmly connected to the frame 5 . The positions of the second tool carrier 4 b relative to the first annular tool carrier 4 a are fixed.

In a second variant, between the second tool carrier 4 b and the further electric motor 15 there is a device which can be changed in length with a translatory drive for this change in length. Such a device are at least two telescopically, tubularly designed and guided elements. The change in length serves as a translational drive a gear / rack system, a threaded nut / threaded spindle system or a traction drive with a chain, a rope or a belt (V-belt, toothed belt) as a traction device, which is guided over at least one drive roller and a deflection roller. With these linear drives, the gear, the threaded spindle or the drive roller is driven. One of the components of this translational drive is permanently coupled to one of the elements. Another variant are roller screw drives. These are particularly characterized by their high rigidity and high axial load capacity. The roller screw drive basically consists of a threaded spindle and a threaded nut. In the threaded nut, axially parallel thread rolls are arranged. If the threaded spindle rotates, the thread rollers rotate planet-like around the threaded spindle without axial displacement. Sprockets guide the thread rolls radially.

In a third variant, the further electric motor 15 and the second tool carrier 4 b have a fixed position in relation to one another. The further electric motor 15 is coupled to the frame 5 via a translatory drive, so that the further electric motor 15 and the second tool carrier 4 b can be moved together with respect to the frame 5 and in the cavity 10 .

The second tool carrier 4 b has a microcomputer system and a further sliding contact system 16 according to the first exemplary embodiment for the energy supply.

The holding structure is designed so that the tool 3 can be releasably attached. In one embodiment, there is a device for absorbing mechanical forces that could otherwise destroy the drive mechanism 17 between the drive mechanism 17 and the holding structure. These are in particular special gear units with integrated liquid or solid damping means or damping devices. In a further embodiment, this device is also used, or at the same time, to change the direction of movement in accordance with the tool 3 used . These devices can be designed so that an angle between equal to / greater than 0 ° and equal to / less than 180 ° can be realized. This is based on known Ge gear arrangements with, among other things, differently designed gears that are used as spur, bevel, screw or worm gears. For a gear stage, these are used in pairs or in a combination. This makes it possible to include tools 3 to be driven for machining the end region of workpieces 2 .
