Description

[0001] MACHINE FOR PROCESSING CAST OR FORGED RIM [0002]

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

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

Machines of this type and methods of this type are known, for example, from US 2006/0048359 A1, in which two sides are provided, one side for drilling, the other side being formed as a separate machine for rotation.

The purpose of this invention is to reduce the actual production time of the outer ring machining.

According to the present invention, in order to achieve the above-mentioned object, in a machine of the type mentioned in the opening paragraph, a workpiece machining position having a workpiece holding device and at least one rotary tool holder for turning the inside contour part is formed and installed, Wherein at least one of the workpiece machining positions is provided with at least one perforator tool holder for a perforator, and at least one of the workpiece machining positions is provided with a perforator tool holder for at least one perforator, It is proposed that the outer ring shafts and perforators are aligned or aligned with respect to each other with respect to the outer ring axle of the outer ring fixed to the workpiece machining position at the application position for forming the valve hole.

The outline section is understood as a surface area to be processed which is located inside the substantially annular outer ring arranged on the vehicle side at the application position in the vehicle and the outline section is disposed on the opposite side of the outline section or away from the in- And is understood as a surface area to be machined located outside the outer ring of the port shape. Thus, the contoured portion can include visible side surfaces and portions of the outer ring rack, particularly visible side outer ring flanges.

Therefore, it is understood that the turning of the inner contour portion is a turning step that can be carried out at the first fixing of the outer ring, and at the time of this first fixing, the surface region to be processed which is located at least inside the outer ring of the port- . Therefore, a machining area that exists on the outer surface of the port-shaped outer ring but is accessible when the first tool is fixed can also be included in the inner contour portion.

Therefore, it is understood that the turning of the outer contour portion is a turning step that can be carried out at the second fixing of the outer ring, and at the time of this second fixing, at least the visible side is accessible for turning.

The present invention can substantially avoid the assist time caused by shifting the outer ring between the respective machining stations, thereby enabling the time actually required to perform the outer ring machining, that is, the pure machining time, And the time can be shortened compared to known machines. The present design also provides other advantages in that each machining station is integrated into one machine, so that the machine area required to perform the entire outer ring machining cycle can be reduced compared to known machines. Thus, in one and the same machine, machining of the entire outer ring from the unworked cast parts to the finished product whose surface has been machined can be carried out.

It may be proposed that the workpiece clamping device (s) are formed as outer ring clamping device (s). In this case, there is an advantage that the deformation of the outer ring is small or the deformation without deformation becomes possible. Here, the clamping force applied on the outer ring for fixation is determined so that the outer ring is not deformed or is not substantially deformed when fixed. This is particularly important in the manufacture of an outer ring made of aluminum, because undesired central imbalance of the outer ring is caused by deformation.

The workpiece fixing device (s) is installed so as to fix the outer ring by the upwardly facing visual side of the outer ring and / or the downwardly directed opening of the port-shaped outer ring so as to easily discharge the chips generated in the turning process Can be proposed. Therefore, in a simple manner, the chip can freely fall downward, and it is possible not to scratch the surface of the high-quality outer ring, and to prevent the machining process from being disturbed. To this end, the first fixation can be provided with a fixed fixation and / or for this, the second fixation can be provided with an upright fixation.

An apparatus for cooling the turning process with cold air may be provided. In this case, there is an advantage that the use of the cooling fluid is eliminated, thereby eliminating the need for a costly refrigerant purifying device, in particular, a filtering device for chips that are cleaned together.

In a compact structure, in particular in a structure requiring as few platforms as possible, it may be proposed that the workpiece clamping 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 clamping device (s) and / or the rotary tool holder and / or the at least one perforator are arranged in a common machine housing, in particular a common sealed workspace. In this case, the entire outer ring machining process has the advantage of being protected in a simple manner from unauthorized or unintended external interference. Here, precision components such as a spindle control device, a glass scale, and a carriage guide can be disposed outside a work space that is encapsulated through a machine housing. Thus, for example, chips or particulates or coolants and lubricants will not be able to damage not only the precision period of precision parts but also cleanliness of the hole bottom and air.

In the configuration of the present invention, it is proposed that a reading device is disposed in front of the first workpiece machining position in the processing flow of the outer ring, and that the reading device is provided for reading a marker attached on the outer ring to be machined . The markers may include, for example, a machining program in encrypted form provided for the outer ring. In this case, the read markers may be used to install on the machine according to the present invention, so as to automatically enable customization for individual outer ring machining. Alternatively or additionally, the markers may be provided to indicate the orientation of the initial orientation, e. G., The 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 positioned in front of the first workpiece machining position in the machining flow of the outer ring, and the positioning device sets the predetermined spatial orientation of the outer ring to be machined . 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 clamping devices is likewise done in the correct position, so that the orientation only has to be set or adjusted only at the beginning of the outer ring machining.

In order to avoid undesired deformation of the outer ring during turning, a rotary tool holder for turning the contoured portion and another rotating tool holder for turning the inner contour portion and / or the outer contour portion, at the workpiece machining position, It may be proposed to arrange the inner contour portion and / or the outer contour portion at the same time for turning at a plurality of processing points of the workpiece. Preferably, the rotary tool holder may be arranged or actuated such that the machining point of the outer ring is disposed on the opposite side of the material wall of the outer ring. This allows each of the rotating toolholders to construct a radially oriented force that is aligned opposite to each other and at least as far as possible offset from each other.

In order to align the perforator and the outer ring with respect to each other to perforate the inclined valve hole, the workpiece machining position with the perforation tool holder includes a device enabling relative rotation between the outer ring fixed to the workpiece machining position and the perforator Can be proposed. In this case, there is an advantage that a valve hole having an arbitrary inclined position with an arbitrary angle with respect to the outer ring shaft can be formed.

Preferably, the pivot axis is horizontally aligned.

Here, the device may comprise a pivotable workpiece clamping device, or it may be proposed that the device comprises a pivotable perforator, or that the workpiece clamping device and perforator can be pivotably mounted by the device .

Alternatively, in a relatively structurally simple construction, it may be proposed that the perforator on the perforation tool holder is arranged fixedly inclined with respect to the rotational axis of the workpiece machining position.

According to the present invention, it is possible to propose that the outer contour portion and the inner contour portion are turned at a common workpiece machining position. In order to further reduce the dead time caused by the tool change, it may be proposed that two separate workpiece machining positions are provided with respective workpiece clamping devices and respective at least one rotating and / or drilling tool holder .

When a separate workpiece machining position is formed, it may be proposed that the workpiece holding device is arranged to transmit the outer ring to the correct position. Therefore, it is preferable to select alignment between the workpiece machining positions so that it is not necessary to change the orientation of the outer ring through evert, for example, between the workpiece machining positions.

For example, it is proposed that the workpiece holding device for turning the inner contour portion and the workpiece holding device for turning the outer contour portion and / or the visual side surface are combined from the opposite spatial directions of the outer race to be machined. To implement as few platforms as possible, this spatial direction can be selected in the vertical spatial direction. In this case, it is advantageous that the workpiece clamping device can be arranged on a horizontal plane which is arranged vertically, on the side opposite to each other with respect to one plane. Such a plane is given through the carrying direction of the outer ring between the workpiece holding devices and can be aligned parallel to the carrying direction. Here, while machining is performed at the workpiece machining position, the workpiece holding device can also penetrate through the imaginary plane.

A rotary tool holder for turning of the contour part and a rotary tool holder for the outer contour part and / or the turning of the visual side can be provided or provided from the opposing, preferably vertical, Can be proposed. Here, the rotary tool holder may be arranged on at least sides opposite to each other with respect to the virtual plane at the initial position, and the rotary tool holder may penetrate the plane during turning.

In the configuration of the present invention, it is proposed that one perforation tool holder is attached to each of the workpiece machining positions. In this case, since the steps of the entire manufacturing process including the turning of the inner contour portion, the turning of the outer contour portion, and the punching of the mounting hole and the valve hole can be assigned to the respective workpiece machining positions, It is advantageous that the production time at the position is substantially the same. Thus, a uniform workpiece flow through the machine can be achieved substantially without latency. For example, a perforator of one workpiece machining position is provided to perforate a mounting hole extending parallel to the outer ring axis, and in particular includes a multiple perforation head to simultaneously puncture at least two mounting holes, The tool holder may be provided to puncture the valve hole.

In one configuration of the present invention, the workpiece clamping device at the workpiece machining position is pivotally and / or displaceably disposed to receive the outer ring to be machined from the loading position and / or to clamp the machined outer ring to a workpiece clamping device It may be proposed to deliver it to the shelf location. In this case, there is an advantage that it is possible to carry the outer ring to the workpiece machining position and to remove the additional mechanical parts for carrying the outer ring between the workpiece machining positions.

It has proved advantageous to attach the drilling tool holder for drilling the valve hole to the workpiece machining position for turning of the outline portion.

In order to remove the generated chip from the outer ring in a simple manner without damaging the surface of the outer ring, the workpiece fixing device at the workpiece processing position for turning of the inner contour portion is provided so as to fix the outer ring by suspending, It may be proposed that the downwardly facing side of the tool can be turned by at least one rotating tool. Thus, the chip can fall from the inside of the outer ring by itself, and can be easily collected and removed.

It may be proposed that the workpiece clamping devices are each arranged on a rotating spindle.

Particularly advantageously, the pivotable workpiece holding device with its own pivot axis is stationary.

To produce an arbitrary contour, it is proposed that the workpiece clamping devices are each displaceable at least in the direction of the axis of rotation of the turning, preferably in the X and Z directions.

To make a complex outline and / or outline, it may be proposed that at least one workpiece machining position comprises at least two rotary tool holders movable independently of one another or in relation to each other. In this case, one turning or perforating tool can be fixedly arranged in one rotary tool holder during the turning process, and the workpiece clamping device to be attached can move the X, Z and, if necessary, the relative movement in the Y direction And the second rotary tool, which is fixed to the other rotary tool holder, is carried by the conveying device together with the workpiece holding device and is moved in the X, Z and, if necessary, in the Y direction There is an advantage that the second movement of the second lens group is overlapped.

A common workpiece machining position is formed or two separate workpiece machining positions are formed for turning of the outline portion and the outline portion, and the machining position of the workpiece for turning of the outline portion and the turning portion It may be proposed that another workpiece machining position is installed.

To achieve this object, in a method of the type mentioned at the beginning, according to the present invention, one of the outline and / or outline contour is turned at the workpiece machining position, and at least the valve hole extending obliquely to the outer ring axis It is proposed to perforate the outer ring fixed to the workpiece machining position without being shifted.

It may be proposed that, between the drilling of the valve hole and the turning, the drilling tool for the fixed outer ring and the valve hole is pivoted relative to each other, in order to perforate the inclinedly extending valve hole in the securing device for turning.

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 hole of the valve hole, or it may be proposed that the drilling tool is turned. Alternatively, the drilling tool can be fixedly aligned at a desired tilt angle.

In one configuration of the present invention, it may be proposed that the outer ring is fixed by suspending for turning of the inner contour portion, and that the side surface, especially the inner contour portion or outer contour portion, facing downwardly of the fixed outer ring is turned. In this case, there is an advantage that the generated chips may not be collected or substantially 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 portion is first turned and then the outer contour portion is turned. In this case, there is an advantage that the visible side, which requires particularly high quality of production, can be finally turned.

The mounting holes have proved advantageous to be drilled and / or perforated from below in a fixedly fixed position. Further, here, accordingly, the generating chip can be simply removed and discharged.

In one configuration of the present invention, it can be proposed that the valve hole is drilled after turning of the outline portion. Thus, the turning motion can be executed after the end of turning.

It may be suggested that the mounting holes be drilled and / or perforated prior to turning of the contoured portion. Thus, the visible side can be machined after the formation of the mounting hole.

The inner contour portion and the outer contour portion are turned at a separate workpiece machining position and the outer ring is shifted between the turning operations so that uniform ability utilization can be achieved. However, it may also be proposed that both turning operations are performed in one and the same workpiece machining position, without shifting.

Here, it is particularly advantageous to maintain the spatial alignment of the outer ring shafts during shifting of the outer ring.

It can be proposed that the outer ring is carried from one workpiece machining position to another workpiece machining position between turning steps by a workpiece holding device attached to one of the two workpiece machining positions. Thus, additional grippers and the like can be saved.

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

The present invention is now described by way of example, but it is not limited to this embodiment. Other embodiments may be formed by combining each feature or feature of the claims with each other and / or including each feature or features of the embodiments.

According to the present invention, it is possible to reduce the actual production time in the outer ring machining.

2 is a front view of the machine according to the present invention for machining cast or forged outer rings;
Figure 3 is a perspective view of the machine according to Figure 2;

Figures 2 and 3 show a machine according to the present invention, generally indicated by reference numeral 1, in a front perspective view, and are described below together.

The machine 1 is installed and equipped for machining cast or forged outer ring 2.

1 shows an axial cross-section through this type of outer ring 2. The outer ring 2 is formed in a substantially pot-shaped shape and includes an inner contour portion 3 and an outer contour portion 4. The outer contour portion 4 includes at least a part of the visible side face 5 and the outer ring flange 6 and the outer ring rack 7. On the other hand, the outline section 3 includes a surface area located inside the port shaped outer race 2, and the surface area lies on the axial end when the outer race 2 is assembled on the axial end of the vehicle. A part of the outer ring rack 7 disposed adjacent to the edge 8 of the port-shaped part is machined together with the inner contour part 3 for the reason of the manufacturing technique and the fixed phase, do.

2, the machine 1 comprises a first workpiece machining position 9 and at the first workpiece machining position 9 the outer ring 2 is fixed on the workpiece clamping device 10, .

The workpiece clamping devices 10 and 14 are generally provided with clamping fingers so that it is possible to fix the outer ring with little or no deformation.

The workpiece machining position 9 also includes at least one rotary tool holder 11 to which a rotary tool 12 for turning can be fixed.

The workpiece machining position 9 is established and formed for turning of the inner contour portion 3 of the outer ring 2.

The machine 1 is also provided with a second workpiece machining position 13 having a second workpiece holding device 14 and a second rotating tool holder 15. The workpiece machining position 13 is provided for machining the outer contour portion 4 of the outer ring 2.

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

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

As shown in Fig. 2, a virtual horizontal plane is defined through the machine 1 through the conveying direction of the outer ring 2 extending from left to right. Workpiece clamping devices 10, 14 are arranged on the side opposite to each other with respect to the imaginary horizontal plane. While the outer ring 2 is being machined, the workpiece clamping devices 10, 14 can of course pass through the imaginary horizontal plane.

Likewise, the rotary tool holders 11, 15 and 33 are also arranged on the side opposite to each other with respect to the horizontal plane, and can pass through the horizontal plane in the vertical alignment movement.

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

3 and 2 show the application position for forming the valve hole into the outer ring 2 by the perforator 25 and the outer ring shaft 18 (see FIG. 1) As shown in FIG.

The workpiece machining position 13 also includes a device 19 which allows the workpiece clamping device 14 to move from the turning position 20 shown in solid line in Figure 2 to the position shown in Figure 3 And can be pivoted to the drilling position 21 shown in phantom in Fig.

In another embodiment, the perforator 25 can be pivoted to an inclined or inclined position or fixedly mounted in this inclined position, and the outer ring 2 is supplied to the turning position 20 for drilling.

Thus, in the machine 1 according to FIGS. 2 and 3, two separate workpiece machining positions 9 and 13 are formed, and the workpiece machining positions 9 and 13 are arranged in a common workpiece machining position May be integrated.

In the machine 1, the rotary tool holders 11, 15 are formed as rotating devices and may have a perforated tool holder.

It is proposed that a multi-perforation head (not shown) is disposed at the workpiece machining position 9 to simultaneously puncture the mounting holes of the outer ring 2 extending axially with respect to the outer ring shaft 18. [ However, the multi-perforation head may be attached to the machining position 13.

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

Fig. 2 shows the outer ring 2 at various machining positions simultaneously during the machining of the outer ring.

Thus, as shown, the workpiece clamping device 10 of the workpiece machining position 9 is moved in the X direction, that is, parallel to the display surface in the horizontal direction in Fig. 2, and in the Z direction That is, vertically displaceable, so that the outer ring 2 can be received from the loading position 23 and fed to the workpiece machining position 9.

The outer ring 2 processed at the workpiece machining position 9 can be carried by the workpiece holding device 14 to the workpiece machining position 13 continuously and then transferred to the workpiece holding device 14. [

3, the shelf position 24 for receiving the finished outer ring 2 can be horizontally operated and the workpiece clamping device 14 can move the outer ring 2 to the shelf position 24 As shown in Fig.

The rotary tool holder 15 of the workpiece machining position 13 is likewise formed as a rotating device and holds the rotary tools 16 and 17 as well as the perforator 25 already described. The rotary tools 16 and 17 are fixed to the workpiece machining position 13 for turning of the outer contour portion 4 of the outer ring 2.

Further, the rotary tool holder 15 is disposed in the composite tool conveying table 26, and is operated in the X and Z directions.

As already described, the work fixing device 10 of the workpiece machining position 9 at which the inward contour of the outer ring 2 is subjected to turning is disposed on the composite tool transfer table 22 in a pseudo manner, Structure is formed.

Through this, the inward contour (3) of the fixed outer ring (2) faces downward and can be turned by the rotary tool (12).

The workpiece clamping devices 10 and 14 are rotated about the rotary shafts 29 and 30 by the rotary spindles 27 and 28 while turning is performed at the workpiece machining positions 9 and 13.

The rotary spindle 27 can be actuated in the X and Z directions in the composite tool delivery table 22 and the rotary spindle 28 is fixed and pivoted by the device 19 about the horizontal axis of rotation, Respectively.

Thus, the workpiece clamping devices 10, 14 and the rotary tool holders 11, 15, 33 and the workpiece machining positions 9, 13 including both of them are disposed on or formed on the common machine stand 31 .

In addition, the machine 1 comprising its own components is placed in a common, sealed and encapsulated workspace in a common machine housing, not shown.

The rotary spindle 28 of the workpiece machining position 13 can be rotated in the Z direction while the rotary spindle 27 can be operated in the Z direction together with the workpiece clamping device 10 at the workpiece machining position 9, Is held in the turning position 20 and the rotary tool holder 15 moves to machine the contour portion 4 on the composite tool conveying table 26.

2, the unprocessed outer ring 2 is provided on the loading position 23, wherein the unprocessed outer ring is a workpiece to be machined in a pick-up manner, Is received by the fixing device (10) and supplied to the workpiece machining position (9).

2, a positioning device (not shown) is disposed in front of the first workpiece machining position 9 in the processing flow of the outer ring from the left to the right, In order to set a predetermined spatial orientation of the image.

The positioning device is likewise controlled by a reading device (not shown) disposed at the left end of the machining section, and the reading device is provided for reading a marker attached on the outer ring 2 to be machined.

The read marker 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 own outer ring shaft 18 by the rotating spindle 27 and is rotated by the rotating tool 12 and the other rotating tool 32, The contour of the contour is turned.

Here, the rotary tool 12 is fixed and held while the turning is performed, and the rotating outer ring is moved. Similarly, the rotary tool 32 held in the rotary tool holder 33 formed as a rotary device is moved 34 along with the movement of the outer ring 2, and the guide movement also overlaps with other movements required for turning by the rotary tool 32. [

Here, the rotary tool holder 11 and the rotary tool holder 33 are arranged for turning of the in-line portion 3 so that simultaneous turning can be performed at a plurality of processing points of the outer ring, On the opposite side of the material wall forming the port wall of the port shaped outer ring. Therefore, the force applied by the rotary tools 12, 32 for turning on the outer ring 2 in a radial direction can be compensated in a linear direction. Thereby, unintended deformation of the outer ring 2 during turning is avoided as much as possible or completely.

The rotary tool 12 and / or the rotary tool 32 are changed after the end of turning of the contour portion 3 or during the two turning steps, and a not-shown drilling tool is provided at the application position, A mounting hole extending axially from the outer ring 2 can be drilled by a drilling tool.

Subsequently, the workpiece clamping device 10 is moved upwardly in the Z direction and also in the X direction above the rotating spindle 28 to transfer the outer ring 2 to the workpiece clamping device 14. [

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

Here, the outer ring 2 is rotated around the rotary shaft 30 via the rotary spindle 28 in the work fixing device 14. [

After turning of the contoured portion 3 the rotary spindle 28 is stopped at a defined position and is pivoted from its vertical alignment position about the horizontal pivot axis by the pivot angle 35 through the device 19, So that it takes an inclined position necessary for perforating the photo valve hole. In this embodiment, the turning angle is 35 DEG, but other turning angles can be set, for example, a turning angle of 10 DEG to 35 DEG can be set. The selection of each turning angle depends on the inclination of the valve hole with respect to the outer ring shaft 18.
