Definitions

  • the invention relates to a rolling unit with a rolling tool and at least one rolling element that can be placed against a workpiece surface under rolling force and is rotatably mounted, as well as with hydraulically actuated means for generating the rolling force and a device connected to the hydraulically actuated means for generating the desired pressure and volume flow Generation of the fluid acting on the rolling force.
  • Rolling units of the type described above are generally known and have proven themselves well in practical use. You will e.g. generally used on tip lathes for the smooth rolling of turned parts. Depending on requirements, such a tool is manually clamped on the machine support by the operator and removed again after use.
  • a known rolling unit in addition to the rolling tool also has a hydraulic device which is connected to the tool via pipes or hoses and has its own pump-motor unit for generating the necessary pressure, so that a rolling unit is formed from a rolling tool, device for Generation of the necessary hydraulic pressure and connecting means between this device and the tool.
  • Such hydraulically loaded tools are therefore not suitable for use on machines in which an automatic or manually controlled tool change takes place during the machining of a workpiece.
  • the invention is therefore based on the object of proposing a rolling unit of the type described at the outset which can remain in the tool turret or in the tool carrier of the associated machine tool as an installed tool or can be changed between a conventional tool turret or tool carrier and a tool magazine assigned to the machine and not, as in the case of hydraulically operated known tools previously necessary, installed separately for each machining of the workpiece and after finishing the machining must be removed every time.
  • this object is achieved in a rolling unit of the type described at the outset in that the rolling tool and the device for generating the desired pressure are constructed as a structural unit and are rigidly connected to one another, connections for energy supply to the device mentioned being provided, which have corresponding connections for supplying energy are connected or connectable to a machine tool.
  • the previously common external hydraulic station as a device for generating the necessary or desired pressure is thereby eliminated and becomes the tool's own device.
  • both the rolling tool and the device for generating the desired pressure each have an independent housing which is rigidly connected to one another. This makes it easier to adjust the power of the tool and the printing device, and to replace worn components more easily.
  • Such a device for generating the desired pressure can be formed from a simple gear pump or vane pump or piston pump, the latter of which can be driven via a cam or an eccentric disc, which can be driven by an associated drive of the machine tool used via its own drive shaft.
  • Such drive devices are often present, for example, in conventional NC lathes or CNC lathes.
  • it makes sense to connect a pressure accumulator between the tool and the piston pump in order to dampen the pressure surges of the piston pump.
  • the roller unit can have a separate clamping shaft for clamping.
  • the clamping shank can preferably have standard dimensions, so that the entire rolling unit fits over such a clamping shank with standardized dimensions into the likewise standardized and customary receptacles of a tool magazine or a turret head of NC-controlled or CNC-controlled machine tools.
  • the necessary drive shaft for the pump can advantageously be rotatably mounted in this clamping shaft.
  • the entire rolling unit according to the invention can be made particularly small if the roller head is designed as a hydrostatic bearing for the rolling element, which is connected to the pressure side of the associated pump with a connecting channel.
  • FIG. 1 shows a rolling unit with a rolling tool 1 with a hydrostatically mounted rolling element 2, which is held and guided in the housing 1 '.
  • This rolling unit shown in FIG. 1 is composed of the functional groups A to E, the functional group A forming the rolling tool 1.
  • the function group B comprises a piston pump 3, which is accommodated in an associated pump housing 3 ', this piston pump 3 acting on the pressure chamber 5 of the rolling tool 1 with its pressure side 4.
  • the housing 1 ' lies directly with a corresponding flat surface on an assigned flat surface of the pump housing 3'. No pipes or hoses are required between the two functional groups.
  • the pressure chamber 5 of the rolling tool 1 also serves as a pressure accumulator 29, which is designed as a spring pressure accumulator in the exemplary embodiment.
  • the interior of this spring pressure accumulator 29, not designated in any more detail has a piston 28 which is acted upon by the pressure medium and which is supported on a cover 45 via a spring 54.
  • the pressure behavior of the pressure accumulator is determined here by the characteristic curve of the spring 54.
  • a seal 49 e.g. can be designed as an O-ring, can ensure the necessary tightness in the area of the pressure connection between the functional groups A and B. However, other types of seals are also possible here.
  • a drive shaft 6 is rotatably mounted in a manner known per se, on which a cam 19 is arranged in a rotationally fixed but axially immovable manner.
  • a piston 23 On the circumferential surface of the eccentric 19 is a piston 23, which is always in by a spring 25 this facility is held.
  • a pump chamber 22 is connected to the cylinder 27 on the suction side of the piston pump 3 via a check valve 24. In a reverse piston stroke, the suction side becomes the pressure side and thus blocks the check valve 24, but opens a check valve 26, whereby pressure oil is provided on the pressure side of the piston pump 3 to supply the pressure chamber 5 of the rolling tool 1.
  • the structure of such a pump is generally known, so that there is no need to go into further detail here.
  • the drive shaft 6 of the piston pump 3 projects into the housing 52 'of an intermediate piece 52 and is connected there via a coupling 7 to an output shaft 8 of a hydraulic motor 9, which is housed in an associated housing 9'.
  • the intermediate piece 52 and the hydraulic motor 9 form the functional groups C and D. Both functional groups lie against one another via corresponding flat surfaces, the functional group C with a further corresponding flat surface being in contact with an assigned flat surface of the piston pump 3 as the functional group B.
  • Flat seals 51 can ensure the necessary tightness.
  • the entire unit is completed by the functional group E, which forms the cover 10.
  • the cover 10 essentially forms a housing 10 ', on which the clamping shaft 11' is provided with preferably standardized dimensions. Furthermore, the housing 10 'has an oil connection 12 which is guided via a channel 21 to the pump chamber 22. Another channel 15, which is also connected to the oil connection 12, is led to the opening 16 of the hydraulic motor 9 and, if a fluid stream 14 is provided accordingly, ensures its drive.
  • Such hydraulic motors and the necessary guidance of the fluid flow are known, so that here too a detailed description of the structure and the mode of operation can be dispensed with.
  • FIG. 3 The necessary hydraulic circuit diagram for the rolling unit shown in FIG. 1 is shown in FIG. 3.
  • the necessary safety valve 30 for protecting the piston pump 3 in the Embodiment of Figure 1 is provided on the rolling tool. At the same time, this represents a sensible safeguard for the hydrostatically operating rolling tool, so that this tool can be safeguarded independently of the pump.
  • This safety valve 30 can then simultaneously take over the pump protection. However, a similar separate protection against overpressure can also be provided on the piston pump 3. Conversely, this pump protection can of course also take over the protection of the hydrostatic tool.
  • the pressure accumulator 29 in FIG. Bladder accumulator was shown schematically, while in the embodiment of Figure 1, the pressure accumulator is a spring pressure accumulator. This is intended to indicate that, of course, different pressure reservoirs can be used and that the device is not restricted to a specific type of pressure reservoir.
  • FIG. 2 shows a, in contrast to the hydrostatic roller head 44 'in the usual way roller head 44, in which a rolling element 2 rests on a support roller 20 and is supported by this.
  • the rolling element 2 is guided in a manner known per se by a cage 18.
  • the roller head 44 is attached to the free end of a piston rod 42, at the other end of which a piston 41 is arranged, which is arranged displaceably in a cylinder space 40 in the usual and known manner.
  • the cylinder chamber 40 On the side facing away from the piston rod 42, the cylinder chamber 40 is closed by a cover 45 with a seal 46, which is preferably designed as an O-ring.
  • a locking ring 47 holds the cover 45 in its position.
  • a throttle valve 61 is installed in the cover 45.
  • the piston 41 also has a seal 48 in the usual and known manner, with which the piston 41 is sealed against the wall of the cylinder space 40.
  • a spring 43 is also provided in the cylinder chamber in the usual way, which force constantly moves the piston 41 and thus wants to retract the piston rod 42.
  • An extension movement of the piston rod 42 with the necessary force is ensured by pressurizing the part of the cylinder chamber 40 facing away from the piston rod, so that the piston rod-free side of the piston 41 is pressurized with corresponding pressure oil and thus the piston rod 42 with the roller head 44 in the direction of the workpiece 13 moves.
  • the tool in the embodiment according to FIG. 2 is thus able to bridge a larger space between the workpiece and the tool than the tool in the embodiment according to FIG. 1.
  • the rolling tool 1 in the embodiment according to FIG. 2, which represents the functional group F there, is in turn followed by the functional group G in the form of a gear pump 34 with the pump housing 34 '. If such a gear pump 34 is used, the throttle valve can be completely closed or can be omitted.
  • the pump housing 34 ' now connects again to the housing 59 of the cover 10 ⁇ , this housing 59 also having the clamping shaft 11 for a tool holder 57.
  • the tool holder 57 is assigned to the machine tool on which the tool is used.
  • the drive shaft 32 for the gears 39 and 39 ' is rotatably mounted in the bearings 38 and 38'. The necessary tightness between the functional groups is restored by the flat seals 51 and, if necessary, by sealing rings 49.
  • a channel 36 feeds the fluid flow 14 via the channel 37 to the gear pump 34, which ensures the necessary pressure of the fluid flow 14 and leads the pressurized fluid flow on the pressure side 4 into the cylinder space 40 of the rolling tool 1.
  • a safety valve 30 is guided to the outside from the pressure side 4 and secures the gear pump 34 against overload. The course of the channels 35, 36 and 37 and 4 is shown in Figure 5.
  • the drive shaft 32 can be connected to a drive shaft 60 of an electric motor 58 via the coupling 33.
  • This electric motor 58 is already present as a drive device in the associated machine tool.
  • Such known CNC-controlled machines usually not only have a drive for the main spindle but also further spindles derived from or separately driven by the drive of the main spindle, with which, if necessary, appropriately used tools, such as a tool according to the figure 2, can be driven.
  • FIG. 4 The hydraulic circuit diagram of the embodiment according to FIG. 2 is shown in FIG. 4.
  • the clamping shaft 11 or 11 ' in its dimensions e.g. comply with DIN 69880.
  • the clamping shaft 11 or 11 ' is brought into operative connection with the tool holder 57 of a machine tool and firmly clamped.
  • the oil connection 12 is also tightly connected to the lubricant circuit of this machine when the tool is clamped in a tool holder or in a tool holder 57.
  • connections of a lubricant circuit which can be used, can already be present in the area of the tool holder of such a machine in a known manner.
  • the rolling tool 1 is now to be rolled on a rotating workpiece 13, then the rolling tool 1 is brought into the working position in the tool holder 57, controlled by the machine control, and the rolling element 2 is positioned in relation to the workpiece 13 such that there is loose contact between the rolling element 2 and the workpiece 13 is present, but no significant forces occur between the rolling element 2 and workpiece 13.
  • the lubricant circuit of the machine tool is then activated and a fluid flow 14 flows through the oil connection 12 into the channel 15 of the hydraulic motor 9 Fluid stream 14 enters through the opening 16 in the gear housing 9 'and acts on the gears 17 and 17', which then convert the flow energy of the fluid stream 14 into rotational energy.
  • the shaft 8 of the gear 17 then drives the drive shaft 6 of the piston pump 3, which has the eccentric 19, via the clutch 7.
  • the fluid flow 14 flowing in through the oil connection 12 flows through the channel 15 and the channel 21 into the pump chamber 22, which envelops the eccentric 19 and the piston 23.
  • the fluid flow 14 thus reaches the check valve 24 or the suction valve of the piston pump 3. If the drive shaft 6 of the piston pump 3 is driven by the hydraulic motor 9, the piston 23 moves back and forth under spring pressure of the spring 25 on the eccentric 19, held in the cylinder 27 .
  • the suction valve 24 opens and fluid is sucked in.
  • the suction valve 24 closes and the pressure valve 26 opens and releases the pump outlet 4.
  • Both valves, suction valve 24 and pressure valve 26, can be designed in their simplest form as conventional check valves.
  • the fluid now enters the pressure chamber 5 of the rolling tool 1.
  • the now translated to a significantly higher pressure than from the lubricant circuit of the machine tool acts on the hydrostatically mounted rolling element 2 and generates the desired rolling force.
  • the rolling element 2 rests against the workpiece 13 under rolling force.
  • the piston 28 of the pressure accumulator 29 is displaced against the spring force of the spring 54 and thus stores the fluid under pressure in order to compensate for pressure irregularities resulting from the design of the piston pump. If a gear pump is used instead of the piston pump, the pressure accumulator could be omitted.
  • the spring 54 which resiliently supports the piston 28, is in turn supported on the free side by the cover 45, which, as also already described, is held in the housing by the locking ring 47.
  • the whole assembly shown in Figure 1 can be rigidly held together in the form of trained as a tie rod and only indicated by lines 50, 50 ', through screws. All function groups A to E are pressed tightly and tightly against one another and form a rigid, solid block that is quite small.
  • the pump drive is connected to a conventional tool drive of the assigned machine tool.
  • the tool drive of the machine tool is shown in FIG. 2 by the drive shaft 60 and the electric motor 58.
  • the oil connection 35 is simultaneously connected to the lubricant circuit of the associated machine tool when the entire unit is clamped in the tool holder.
  • the rolling tool is held in the tool carrier or in the tool holder 57 and brought into the working position controlled by the machine control so that the rolling element 2 is at a short distance from the surface of the workpiece 13 to be machined.
  • the lubricant circuit of the machine tool is then activated and a fluid stream 14 flows through the oil connection 35 into the channel 36 of the gear pump 34 and enters the channel 37, which is formed by the interior of the pump housing 34 '.
  • the inflowing fluid is brought to a pressure suitable for operating the rolling tool 1 and flows through the pressure side 4 into the cylinder chamber 40, whereby the piston 41 with the piston rod 42 against the spring force of the Spring 43 is moved.
  • the rolling element 2 which is carried by the roller head 44, is pressed against the rotating workpiece 13, as a result of which the required rolling force is built up.
  • the vent hole 53 ensures that there is no undesirable back pressure in the installation space 55 for the spring 43.
  • a gear pump in the construction of the unit according to FIG. 2 makes it possible to dispense with a pressure accumulator there.
  • a piston pump could also be used.
  • the throttle valve must be opened slightly so that a pressure reduction can take place in the cylinder chamber 40 when the piston pump is at a standstill. If the throttle is opened further, this can serve as a pressure control unit in cooperation with the pump speed. since the throughput through the throttle is largely dependent on the pressure drop across the throttle. With a piston pump, for example, the full pump pressure is created when the throttle is closed, even at low speed. If the throttle is now opened, the pressure drops depending on the opening cross-section. It can now be increased again by increasing the pump speed.
  • FIG. 6 now shows an exemplary embodiment in longitudinal section, in which the rolling tool 1 is connected to a holding shaft 62, which is designed for holding in the work spindle or main spindle of a machine tool, for example a milling machine.
  • the receiving shaft 62 can be designed in a conventional manner.
  • an intermediate region 64 is provided between the rolling tool 1 and said end of the holding shaft 62 and is fixedly connected to the holding shaft 62, which rotates with the holding shaft and which has a piston pump 65.
  • a radial bore 72 in which a piston 73 is inserted, can simply be provided in the intermediate region 64 mentioned.
  • the piston 73 is preloaded by a spring 74, which is supported on the one hand at the intermediate region 64 mentioned and on the other hand on a collar 75 of the piston 73.
  • the radial bore 72 is connected on the suction side via a check valve 76 to a supply line 78, via which the necessary fluid is supplied, for example from the circuit of the machine tool.
  • a further check valve 77 is provided, through which the pressure oil is supplied to the rolling tool 1, which in the exemplary embodiment shown in FIG. 6 is designed as a roller head with a hydrostatically mounted roller.
  • the pressure line 79 leading to the roller head is connected via a connecting line 80 to a pressure accumulator 70, which is also arranged in the intermediate region 64 and therefore rotates together with the rolling tool 1 and the machine spindle 71.
  • the pressure accumulator 70 can be designed as a spring pressure accumulator, as has already been described for FIG. 1.
  • the intermediate area 64 is covered over part of its longitudinal extent or width by a ring 67 which is rotatably mounted in this intermediate area 64, for example via roller bearings 81. Collars 82 and 83 ensure axial immovability.
  • the ring 67 has on its inside an inner cam track 68, against which the actuating cam 66 of the piston 73 abuts and is held in contact by the spring 74.
  • Torque support 69 which is supported on any holding part 84 of the machine tool 63. If the machine spindle 71 is now rotated, the entire structure described, with the exception of the ring 67, also rotates.
  • the actuating cam 66 of the piston 73 of the piston pump 65 runs along the inner cam track 68 of the ring 67 and is thereby set into a radial oscillating movement, that is to say into the necessary pumping movement.
  • the necessary fluid is supplied through the supply line 78 and brought to the necessary pressure for the rolling tool 1 by the piston pump 65.
  • the pressure fluctuations that always occur with a piston pump are absorbed by the pressure accumulator 70.
  • the rolling tool 1 can now be guided with its rolling element 2, for example, against the flat surface 85 of a workpiece, which is not described in more detail, and can perform smooth rolling machining there. Due to its eccentric position to the axis of rotation 86, the rolling element 2 describes a circle on the flat surface 85.
  • a linear feed movement of the tool in the direction of arrow 87 by a corresponding displacement of the machine spindle 71 ensures that these circles are superimposed, so that a flat surface of a workpiece can be rolled smooth path by path with such a tool.
