Description

Machine and method for processing cast or forged outer ring {MACHINE FOR PROCESSING CAST OR FORGED RIM AND CORRESPONDING METHOD}

The present invention relates to a machine for machining cast or forged outer ring through turning operation of the inner contour, turning of the outer contour, and drilling of mounting holes and valve holes extending obliquely to the outer ring shaft.

The present invention also relates to a method for machining a cast or forged outer ring through turning of an inner contour, turning of an outer contour, and drilling of a mounting hole and a valve hole extending obliquely to the outer ring shaft.

Machines of this type and methods of this type are known, for example, from US 2006/0048359 A1, where two working areas are provided which are formed as separate machines for drilling on one side and for rotation on the other.

An object of the present invention is to reduce the actual production time during the outer ring processing.

According to the present invention, in order to achieve the above object, in the machine of the type mentioned at the outset, a workpiece machining position is formed and installed, which has a workpiece holding device and at least one rotary tool holder for turning of the inner contour, A workpiece machining position having a workpiece holding device and at least one rotary tool holder is formed and installed for turning the outer contour portion, and at least one of the workpiece machining positions is assigned with at least one punching tool holder for a perforator; It is proposed that the outer ring shaft and the perforator are aligned or alignable with respect to each other inclined with respect to the outer ring shaft of the outer ring fixed at the workpiece machining position in the application position for forming the valve hole.

The inner contour is understood to be a surface area to be machined which is located inside of an approximately port-shaped outer ring, which is disposed towards the vehicle at the application position in the vehicle, the outer contour being approximately spaced apart from or opposite the inner contour of the inner contour. It is understood that the surface area to be machined is located outside the outer ring of the port shape. Thus, the outer contour may comprise part of the visible side and the outer ring rack, in particular the visible side outer ring flange.

Accordingly, the turning of the inner contour is a turning step that can be executed at the time of the first fixation of the outer ring, which is understood to be accessible to the surface area to be machined which is located at least inside the outer ring of approximately port shape. . Thus, a machining region present on the outer surface of the port shaped outer ring but accessible at the time of the first fixation may also be included in the inner contour.

Accordingly, the turning of the outer contour is understood to be a turning step that can be performed at the time of the second fixation of the outer ring, at which time it is understood that at least the visible side is accessible for turning.

The present invention can roughly avoid the auxiliary time caused by shifting the outer ring between each machining station, whereby the time actually required to carry out the outer ring machining, i.e. the pure machining time and the auxiliary present in between It provides the advantage that the sum of time can be shortened compared to known machines. The present invention also provides another advantage that the machining area required for executing the entire outer ring machining cycle can be reduced compared to known machines since each machining station is integrated in one machine. Thus, in one and the same machine, the entire outer ring processing from the unprocessed cast part to the finished product whose surface is cut can be executed.

It may be proposed that the workpiece holding device (s) are formed as outer ring holding device (s). In this case, there is an advantage that the deformation of the outer ring can be fixed with little or no deformation. Here, the clamping force exerted on the outer ring for fixing is determined so that the outer ring is not deformed or approximately deformed at the time of fixing. This is particularly important in the manufacture of outer rings made of aluminum, because deformation creates unwanted central imbalance of the outer rings.

In order to be able to easily discharge chips generated during turning, the workpiece holding device (s) are installed to fix the outer ring by the upward visible side of the outer ring and / or the opening facing down the port-shaped outer ring. It may be suggested to be. Thus, in a simple manner, the chip can fall freely downward, making it possible not to scratch the surface of the outer ring made of high quality and not to disturb the machining process. To this end, the first fixation may be provided as a suspension fixation and / or for this purpose, the second fixation may be provided as an upright fixation.

An apparatus for cold cooling the turning may be provided. In this case, there is an advantage in that the use of the cooling fluid is eliminated, thereby eliminating the need for an expensive refrigerant purification device, in particular a filtration device of the chips washed together.

In compact structures, in particular in structures requiring as few platforms as possible, it may be proposed that the workpiece holding device (s) and / or the rotary tool holder and / or the at least one perforator are arranged on a common machine stand.

It may be proposed that the workpiece holding device (s) and / or the rotary tool holder and / or the at least one perforator are arranged in a common machine housing, in particular in a common sealed working space. In this case, there is an advantage that the entire outer ring machining process is protected in a simple manner from unauthorized or unintended external interference. Here, precision components such as spindle controls, glass scales and carriage guides can be placed outside of the working space encapsulated through the machine housing. Thus, for example, chips or particulates or coolants and lubricants cannot be impaired not only for the precise period of precision parts, but also for the cleanness of the hole bottom and air.

In the configuration of the present invention, it may be proposed that a reading device is arranged in front of the first workpiece processing position in the machining flow of the outer ring, and the reading device is provided for reading a marker attached on the outer ring to be machined. . The marker may, for example, comprise a machining program in the form of an encryption provided for the outer ring. In this case, the read markers can be used to be installed in the machine according to the present invention, so as to automatically enable customization for individual outer ring machining. Alternatively or additionally, the marker may be provided to indicate an initial orientation, eg, alignment of the outer ring spokes, or the orientation of the outer ring mounting holes to be formed. Thus, the read or identified marker can be used for the control of the positioning device located in front of the first workpiece machining position in the machining flow of the outer ring, which positioning device sets the preset spatial orientation of the outer ring to be machined. It is installed to In this case, there is an advantage that the outer ring can be automatically provided in a limited alignment and position. This is particularly advantageous when the switching between the workpiece holding devices is likewise done in the correct position so that the orientation only needs to be set or adjusted at the beginning of the outer ring machining.

In order to avoid undesired deformation of the outer ring during the turning operation, a rotary tool holder for turning the inner contour and another rotating tool holder for turning the inner contour and / or the outer contour in the workpiece machining position, It may be proposed to be arranged for simultaneously turning the inner contour and / or the outer contour at a plurality of machining points of. Preferably, the rotary tool holder can be arranged or actuated such that the machining point of the outer ring is arranged on the opposite side of the material wall of the outer ring. This allows each of the rotary tool holders to establish radially oriented forces that are aligned opposite each other and at least cancel each other out as much as possible.

In order to align the perforator and the outer ring with respect to each other to drill the inclined valve hole, the workpiece machining position with the perforated tool holder includes a device that enables relative turning between the outer ring and the perforator fixed at the workpiece machining position. Can be suggested. In this case, there is an advantage that a valve hole having any inclined position having any angle with respect to the outer ring shaft can be formed.

Preferably, the pivot axis is aligned horizontally.

Here, it may be proposed that the device may comprise a pivotable workpiece fixation device, or that the device may include a pivotable perforator or that the workpiece fixation device and the perforator may be pivotally installed by the device. .

Alternatively, in a structurally relatively simple configuration, it may be proposed that the perforator on the drilling tool holder is arranged fixedly inclined relative to the axis of rotation of the workpiece machining position.

According to the present invention, it can be proposed that the outer contour and the inner contour are turning at a common workpiece machining position. In order to further reduce the dead time caused by tool change, it may be proposed that two separate workpiece machining positions are formed having each workpiece holding device and each at least one rotating and / or drilling tool holder. .

If a separate workpiece machining position is formed, it may be proposed that the workpiece holding device is arranged to deliver the outer ring to the correct position. It is thus possible to select the alignment between the workpiece machining positions so that it is not necessary to change the orientation of the outer ring, for example through an invert, between the workpiece machining positions.

For example, a workpiece fixing device for turning the inner contour and a workpiece fixing device for turning the outer contour and / or the lateral side may be proposed to join the outer ring to be machined from opposite spatial directions. In order to implement as few platforms as possible, this spatial direction may be chosen in the vertical spatial direction. In this case, the workpiece holding device has the advantage that it can be arranged in a horizontal plane arranged vertically, on the side opposite to each other with respect to one plane. This plane is given through the conveying direction of the outer ring between the workpiece holding devices and can be aligned parallel to the conveying direction. Here, while the machining takes place at the workpiece machining position, the workpiece holding device can also penetrate through the virtual plane.

Rotary tool holders for turning of the inner contours and rotary tool holders for turning of the outer contours and / or the visible side feed or provide the respective machining tools from opposite, preferably vertical, spatial directions It may be suggested to. Here, the rotary tool holder may be arranged on sides opposite to each other with respect to the virtual plane at least in the initial position, and the rotary tool holder may pass through the plane during turning.

In the configuration of the present invention, it may be proposed that one drill tool holder is assigned to each workpiece machining position. In this case, for each outer ring to be manufactured, the steps of the entire manufacturing process consisting of turning of the inner contour, turning of the outer contour, and drilling of mounting holes and valve holes can be assigned to both workpiece machining positions, thereby machining both workpieces. The advantage is that the manufacturing time at the location takes about the same. Thus, a uniform workpiece flow through the machine can be achieved without substantially waiting time. For example, a perforator in one workpiece machining position is provided for drilling a mounting hole extending parallel to the outer ring axis, in particular including a multiple drilling head to simultaneously drill at least two mounting holes, and drilling in another workpiece machining position. The tool holder may be provided to drill the valve hole.

In one configuration of the present invention, the workpiece holding device at the workpiece processing position is pivotally and / or displaceably arranged to receive the outer ring to be machined from the loading position and / or to receive the machined outer ring at the other workpiece processing position or Delivering to the shelf position may be suggested. In this case, there is an advantage that it is possible to remove additional mechanical parts for carrying the outer ring to the workpiece machining position and for transporting the outer ring between the workpiece machining positions.

Drilling tool holders for drilling valve holes have proven to be advantageously assigned to the workpiece machining position for turning of the outer contour.

In order to remove the generated chips from the outer ring in a simple manner without damaging the surface of the outer ring, the workpiece fixing device at the workpiece machining position for turning of the inner contour is installed to suspend the outer ring in suspension, and the fixed outer ring It can be proposed that the downward facing side of can be turned by at least one rotary tool. Therefore, the chip itself falls from the inside of the outer ring, and can be easily collected and removed.

It may be proposed that the workpiece holding device is arranged on a rotating spindle, respectively.

Particularly advantageously, a rotatable work holding device having its own pivot axis is fixedly arranged.

In order to fabricate any contours, it may be proposed that the workpiece fixing device is displaceably arranged at least in the direction of the rotation axis of the turning, preferably in the X and Z directions, respectively.

In order to fabricate complex inner contours and / or outer contours, it may be proposed that the at least one workpiece machining position comprises at least two rotary tool holders which are movable independently of one another or in relation to one another. In this case, one turning or drilling tool may be fixedly placed in one rotary tool holder during the turning process, and the doubled workpiece holding device may be subjected to relative movement in the X, Z and, if necessary, Y directions for manufacturing. And a second rotary tool which is fixed to another rotary tool holder is carried by the conveying device together with the workpiece holding device in the X, Z and, if necessary, Y directions for the conveying movement and turning by the rotary tool. There is an advantage that the second movement of is overlapped.

A common workpiece machining position is formed for turning the inner contour and the outer contour, or two separate workpiece machining positions are formed. It may be suggested that other workpiece machining positions be installed.

In order to achieve the above object, in the method of the type mentioned at the outset, according to the present invention, one of the inner contour and / or the outer contour is turned at the workpiece machining position, and at least the valve hole extending obliquely to the outer ring shaft is It is proposed to be drilled without shifting on the outer ring fixed at the workpiece machining position.

In order to drill the obliquely extending valve hole in the fixing device for turning, it may be proposed that a fixed outer ring and a drilling tool for the valve hole are pivoted with respect to each other between the turning and the drilling of the valve hole.

Here, it may be proposed that the fixed outer ring is pivoted to an inclined position corresponding to the inclined position of the valve hole with respect to the outer ring shaft before the drilling of the valve hole or the drilling tool may be proposed to be pivoted. Alternatively, the drilling tool can be fixedly aligned at the desired angle of inclination.

In one configuration of the present invention, it may be proposed that the outer ring is suspending fixed for turning of the inner contour, and the side facing down of the fixed outer ring, in particular the inner contour or outer contour, is turned. In this case, there is an advantage that the chip generated may not be collected or substantially not collected inside the outer ring where damage of the outer ring surface may occur.

In one configuration of the present invention, it may be proposed that the inner contour is first turned afterwards. In this case, there is an advantage in that the visible side, which requires particularly high production quality, can be finally turned.

The mounting hole has proved advantageous to be drilled and / or drilled from below in a suspended fixation. Also here, accordingly, the generation chip can be simply removed and discharged.

In one configuration of the present invention, it may be proposed that the valve hole is drilled after turning of the outer contour portion. Thus, the pivot movement can be carried out after the end of the turning process.

It may be proposed that the mounting hole is drilled and / or drilled before turning of the outer contour. Thus, the visible side can be machined after the formation of the mounting hole.

As the inner contour and outer contour are turned at separate workpiece machining positions, and the outer ring is shifted between turning operations, uniform capacity utilization can be achieved. However, it may be proposed that both turning operations be performed without the shifting inserted in one and the same workpiece machining position.

It is particularly advantageous here to maintain the spatial alignment of the outer ring shaft while the outer ring is shifted.

It may be proposed that the outer ring is conveyed from one workpiece machining position to another workpiece machining position between turning operations by means of a workpiece holding device assigned to one of both workpiece machining positions. Thus, additional grippers or the like can be saved.

In one configuration of the present invention, it may be proposed that the inner contour and / or the outer contour are turned at one and the same fixing portion that also drills the mounting hole. In this case, there is an advantage that the shifting time can be saved.

The rotary tool holder 15 also includes a tool holder 16 as shown in detail in FIG. 3, in which a tool 17 is fixed.

Thus, the tool holder 16 is likewise assigned to the workpiece machining position 13.

As shown in FIG. 2, the virtual horizontal plane is defined via the machine 1 through the conveying direction of the outer ring 2 extending from left to right. Work holding devices 10 and 14 are arranged on sides opposite to each other with respect to the imaginary horizontal plane. While the outer ring 2 is being machined, the workpiece holding devices 10, 14 can of course penetrate the virtual horizontal plane.

Similarly, the rotary tool holders 11, 15, 33 are also arranged on sides opposite to each other with respect to the horizontal plane, and can penetrate the horizontal plane during vertical alignment movement.

Thus, the workpiece holding devices 10, 14 engage the outer ring 2 from the direction of the vertical space opposite to each other. Thus, it is possible to transfer the outer ring 2 to the correct position between the workpiece machining positions 9 and 13.

In FIG. 3 and FIG. 2, the application position for forming the valve hole into the outer ring 2 by the drilling machine 25 is shown by the dotted line, and the outer ring shaft 18 (see FIG. 1) is the axis of the drilling machine 25. Are aligned to be inclined.

The rotary tool holders 11, 15 in the machine 1 are formed as rotary devices and may hold perforated tool holders.

It is proposed that the workpiece machining position 9 is arranged with an unshown multi-perforation head which simultaneously drills the mounting holes of the outer ring 2 extending axially with respect to the outer ring shaft 18. However, the multiple drilling head may be assigned to the machining position 13.

Thus, not only the respective turning operations but also the drilling operations steps can be performed at the workpiece machining positions 9 and 13 of the machine 1.

2 shows the outer ring 2 in several machining positions simultaneously during the entire outer ring machining.

Thus, as shown, the workpiece holding device 10 in the workpiece machining position 9 is parallel to the display surface and in the Z direction in the X direction, ie in the horizontal direction in FIG. 2 by means of the compound tool carriage 22. In other words, disposed so as to be displaceable in the vertical direction, the outer ring 2 can be received from the loading position 23 and supplied to the workpiece machining position 9.

By means of the workpiece holding device 14, the outer ring 2 machined at the workpiece processing position 9 can subsequently be transported to the workpiece processing position 13, where it can be transferred to the workpiece holding device 14.

As shown in FIG. 3, the lathe position 24 for accommodating the finished outer ring 2 can be operated horizontally, and the workpiece fixing device 14 moves the outer ring 2 to the lathe position 24. It is pivotally arranged to transmit.

The rotary tool holder 15 at the workpiece machining position 13 is likewise formed as a rotary device and holds not only the previously described perforator 25 but also the rotary tools 16, 17. The rotary tools 16, 17 are fixed for turning of the outer contour 4 of the outer ring 2 and are provided at the workpiece machining position 13.

In addition, the rotary tool holder 15 is disposed on the compound tool carriage 26 and operated in the X and Z directions.

As already explained, the workpiece holding device 10 at the workpiece machining position 9 where the turning of the inner contour of the outer ring 2 is performed is suspended on the compound tool carriage 22 and picked up therethrough. The structure is formed.

While turning is carried out at the workpiece machining positions 9, 13, the workpiece holding devices 10, 14 are rotated around the rotary shafts 29, 30 by the rotary spindles 27, 28.

The rotary spindle 27 can be operated in the X and Z directions on the compound tool carriage 22, and the rotary spindle 28 is fixed to the machine stand 31 so as to be pivotable by the device 19 around the horizontal axis of rotation. It is mounted on the top.

Thus, the workpiece holding device 10, 14 and the rotary tool holders 11, 15, 33 and the workpiece machining positions 9, 13 comprising both of them are arranged or formed on a common machine stand 31. .

In addition, the machine 1 comprising its parts is arranged in a common sealed encapsulated work space in a common machine housing not shown.

While the rotary spindle 27 in the workpiece machining position 9 can be operated in the Z direction with the workpiece holding device 10, the rotary spindle 28 of the workpiece machining position 13 is upright during turning. Retained at the turning position 20, the rotary tool holder 15 moves to machine the outer contour 4 on the compound tool carriage 26.

Thus, when the entire outer ring machining is made in the machine 1, according to FIG. 2, the unworked outer ring 2 is provided on the loading position 23, where the unworked outer ring is executed in a pick-up manner. It is received by the fixing device 10 and supplied to the workpiece machining position 9.

The read markers can also be used to automatically program the machine 1 in accordance with the machining program provided to the entered outer ring 2.

In the workpiece machining position 9, the fixed outer ring 2 is rotated about its outer ring axis 18 by means of a rotary spindle 27 and its own by means of the rotary tool 12 and other rotary tools 32. The inner contour is turned.

Here, the rotary tool 12 is held fixed during the turning process, the outer ring to be rotated is moved, and the rotary tool 32 held in the rotary tool holder 33 formed as a rotary device likewise is a composite tool feed table ( Guided together with the movement of the outer ring 2 by 34), the guide movement also overlaps with other movements necessary for turning by the rotary tool 32.

Here, the rotary tool holder 11 and the rotary tool holder 33 is arranged for turning of the inner contour 3, the simultaneous turning may be performed at a plurality of machining points of the outer ring, the machining point is It is possible on opposite sides of the material wall forming the port wall of the port shaped outer ring. Thus, the force exerted for turning on the outer ring 2 radially by the rotary tools 12, 32 can be compensated in the linear direction. In this way, unintentional deformation of the outer ring 2 is avoided as possible or completely during turning.

After the end of the turning of the inner contour 3 or during the two turning steps, the rotary tool 12 and / or the rotary tool 32 are changed and a drilling tool, not shown, is provided in the application position, said By means of a drilling tool a mounting hole extending axially in the outer ring 2 can be drilled.

Subsequently, the work holding device 10 is moved upwards in the Z direction and also in the X direction up to the rotating spindle 28 to transmit the outer ring 2 to the work holding device 14.

After the outer ring 2 is delivered, the workpiece holding device 10 is operated back onto the loading position 23 to receive the next outer ring 2.

The outer contour 4 of (2) is processed.

Here, the outer ring 2 is rotated around the rotating shaft 30 through the rotating spindle 28 in the workpiece holding device 14.

After turning of the inner contour 3, the rotary spindle 28 is stopped at a defined position and pivoted through its device 19 from its vertical alignment position about a horizontal pivot axis by a pivot angle 35. The oblique position required to drill the photographic valve hole is taken. In this embodiment, the turning angle is 35 °, but other turning angles may be set, for example, a turning angle of 10 ° to 35 ° may be set. The choice of each turning angle depends on the inclination of the valve bore with respect to the outer ring shaft 18.
