Description

Technical Field

[0001] This invention relates to machines and methods for repairing vehicle rims, and more particularly to machines and methods for the comprehensive repair of motorcycle rims, wherein the configuration requirements of the center hub of these types of rims differ from those of conventional automobile rims or similar rims which are fastened to the vehicle's axle by a few bolts. Background Technology

[0002] Several machines for repairing vehicle rims, particularly automobile rims, have been disclosed in the prior art. It is well known that automobile rims are bolted to the axle of a vehicle, typically with four bolts passing through holes arranged in the center of the rim's hub. Therefore, in order to secure the rim in the machine for repair, the coupling must be similar to that used for automobile rims.

[0003] These solutions for securing car rims to repair machines are widely known in the market.

[0004] Furthermore, for motorcycle rims, it is known that in a typical configuration of a rim made from a single forged piece, there is a center hub with two bearings arranged inside, spaced apart from each other and axially aligned so that an axle on which it rotates passes through. Thus, in order to repair this type of motorcycle rim and ensure its concentricity relative to the axis of rotation after repair, it is ideal that the rim is fastened in a manner similar to or identical to that of the rim in the motorcycle frame.

[0005] For a machine used to repair motorcycle rims, Brazilian utility model MU 8801119-4 and patent PI 0305007-6A, also from Brazil, have been disclosed in the prior art.

[0006] The aforementioned utility model discloses a machine for straightening metal-spoke motorcycle rims, wherein it is unclear how the rim is secured in the machine for subsequent rotation and straightening by a series of rollers, thereby straightening deformed portions of the rim as they pass through these rollers. This utility model does not disclose the fastening or coupling of the rim to the machine, and furthermore, the use of rollers to perform the straightening process may limit the full repair of the rim.

[0007] Furthermore, similar to the referenced utility model, Brazilian patent PI0305007-6 discloses a machine for repairing radial motorcycle rims, wherein the rim is fastened by two threaded horizontal metal rods, each threaded horizontal metal rod being disposed in a vertical column of the machine structure and actuated by a crank disposed at the outer end of the threaded metal rod. The opposite ends of the rods, in other words, the ends of each rod facing inwards towards the machine, are pulled together by the actuation of the crank, causing them to press against the wheel hub, with each end residing on a bearing disposed in the hub without passing through them. Further, as described in this patent document, the bent portion of the rim is arranged between a pair of clamps mounted in the structure, such that vertical straightening is produced by manually activating a hydraulic jack disposed at the lower part of the structure, which pulls the damaged portion of the rim, stretching the area to perform straightening; while horizontal straightening is performed by a lower horizontal crank, which in the same manner supports and adjusts the damaged area.

[0008] This Brazilian patent reveals that fastening the compressed rim to the bearing of the hub may affect the hub's structure. Furthermore, since the bearing does not pass through, the rim's concentricity cannot be guaranteed once repaired. It also shows that straightening the affected portion of the rim is limited by the shape and tightness of the clamp, thus failing to address the overall rim repair issue.

[0009] It is important to note that the machine disclosed in the cited Brazilian document was not intended for repairing motorcycle rims made of light alloys forged from a single piece, and is therefore limited to radial rims made of steel.

[0010] Therefore, there is a need for a machine, system, and / or method that may be used for comprehensive repair of motorcycle rims, including straightening and / or machining, wherein the rim is fastened while it is fastened into the motorcycle itself to ensure concentricity of the rim relative to its axis of rotation after repair. Summary of the Invention

[0011] To address the identified need, the present invention provides a machine for repairing various motorcycle rims, comprising a rigid frame formed by two vertical columns connected by an intermediate base plate and an upper crossbar. A head base, rotatably mounted thereon, is coupled to the intermediate base plate and is configured to rotate freely relative to a main axis or by means of a transmission device suitably connected thereto. A locking device configured to lock the head is also arranged in the intermediate base plate.

[0012] The head structure, which will be described in detail in later chapters, is designed to enable smooth rotation while providing high resistance to lateral tension and / or vertical thrust generated thereon by the various actuators of the machine used to straighten the rim.

[0013] It is important to note that the machine design of this invention is intended for motorcycle rims preferably forged from a single alloy material, such as a high-strength, lightweight aluminum alloy. In some models of these rims, the center hub, or simply the hub, is configured such that two bearings are mounted therein, axially spaced relative to the axis of rotation of the rim, such that when mounted in a motorcycle, the inner ring of the bearing passes through an axle adjusted to the ring, causing the wheel to rotate relative to the axle due to the bearings. In another embodiment of the rim, the hub is intended to be bolted to the motorcycle axle, similar to the coupling method of automobile rims.

[0014] Given the different modes of the rim, one of the main objectives of the machine of the present invention is to achieve coupling of any type of rim in the machine by mimicking the coupling of the rim in the machine as in the coupling in a motorcycle chassis, thereby ensuring the concentricity of the rim relative to its axis of rotation after repair.

[0015] Therefore, for the installation and repair of the rim in the machine, the head is locked by a locking device and coupled thereto by a fastening tool configured to pass through the rim hub. Once the tool has been coupled, the rim is positioned horizontally, and the hub is passed through and coupled by the tool. The tool is then coupled to a vertical support rod movable by the upper crossbar of the frame. This coupling allows the rim to rotate relative to its axis of rotation, which, as those skilled in the art will understand, coincides with the main axis of rotation of the head relative to it. In this way, the rim rotates as if it were placed in a motorcycle, thus making it easier to identify rim deformation using the measuring devices provided in the machine.

[0016] This type of hub fastening allows for better application of tension to the affected parts of the machine that are being straightened.

[0017] Depending on the size of the wheel hub and / or the bearing mounted in the hub, it may be necessary to use an adapter that can be coupled to the tool, configured to engage within the wheel hub and / or bearing. Typically, two similar adapters are used, one on each side of the hub, to maintain rim stability during servicing.

[0018] The operator can work while sitting on a stool in front of the machine. The stool is at a suitable height so that when observing and detecting rim deformation, the observation point is located at the height of the rim deformation measuring device, thus allowing the operator to work in the most ergonomic way.

[0019] The machine's measuring device can be mounted on one side of the head, for example, on the left side of the head when the machine is viewed from the front, while the actuator with the energy distribution system is located on the opposite side, in other words, on the right side of the head, which facilitates the use of the machine.

[0020] To detect defects and continue repairing the rim, it is preferable to rotate the rim counterclockwise when viewed from above the machine. Since the device for measuring deformation is mounted on the left side, the operator can see the device for measuring rim deformation without visual fatigue when the rim is rotated.

[0021] Furthermore, the machine features a straightening device, as its name suggests, configured to straighten wheel rims. This straightening device is a combination of actuators and tools, particularly well-suited for addressing and removing various deformations of the wheel rims. As part of this straightening device, a first actuator is arranged in one of the vertical columns of the frame, for example, in the right vertical column. This actuator is vertically movable by the vertical column and can be locked in position when it is at its working point. The first actuator includes an adjustment mechanism configured to adjust its stroke and / or displacement relative to itself to be adjusted to the size and / or diameter of the wheel rim, thereby enabling tools mounted in the first actuator to perform their work more effectively.

[0022] Similarly, a second actuator for vertical upward / downward thrust can be coupled to the upper crossbar of the machine frame, and this second actuator is displaceable within the upper crossbar. The second actuator is also displaceable in a direction substantially perpendicular to the upper crossbar, allowing it to be appropriately adjusted to the size of the rim to be repaired.

[0023] The intermediate base plate includes a lower part, through which a third actuator for vertical upward thrust is displaceable, and this third brake is used as a support during the repair of rim deformation.

[0024] Furthermore, a guide block is integrated into the upper crossbar, through which the vertical support rod is vertically movable. At one end, the vertical support rod includes a housing configured to rotatably couple the fastening tool. Thus, when the vertical support rod is lowered, the tool is coupled to it to provide sufficient structural strength for the tool when the actuator applies force to eliminate deformation during rim repair. In this way, the tool is not damaged, and the rim is repaired relative to its axis of rotation.

[0025] Repair tools with different configurations and shapes can be coupled to the first, second, and third actuators to address different deformations that may exist in the rim. Similarly, the application of actuators can be performed individually or in combination on the rim, thereby eliminating all deformations of the rim in conjunction with the repair tools.

[0026] Once the rim has been straightened and aligned, and if necessary for maintenance, it can be machined. For this purpose, the fastening device includes a clamping plate replacing the fastening tool in the head, and a tool is mounted in a vertical support rod, specifically for preparing the rim for fastening during machining. This tool is axially adjustable in the vertical support rod to fasten the rim by pressure and lock it to the hub.

[0027] The rim is placed between the clamping plate and the tool, residing on one side of the hub, in an adapter that can be coupled to the clamping plate, the adapter being configured to engage in a bushing and / or bearing, and the tool is coupled to the opposite side of the rim hub, the vertical support rod is lowered and the tool is axially adjusted in the vertical support rod to couple the rim hub and press it against the clamping plate.

[0028] After the rim is coupled in this way in the machine, the head is rotated by the transmission device, thereby rotating the rim so that it can be processed by a processing device that is coupled and displaceable by the vertical columns of the frame.

[0029] The processing apparatus includes a support, a tool carrier coupled to the support, the tool carrier being configured to move relative to the support and to carry a cutting tool, the cutting tool being configured to remove material from the rim by relative movement between the cutting tool and the rim.

[0030] The machining of the rims is performed by the operator sitting on a stool on the right rear part of the machine, which includes an electrical system, a lighting system, a transparent plastic protector installed to protect the operator from any particles released by the machine during operation, as well as safety goggles and safety stops.

[0031] When machining begins, the operator positions the cutting tool at the height of the rim portion to be machined, and high-quality machining is achieved as the tool carrier moves, because, similar to rim straightening and centering, the rim loses almost no two to three tenths millimeters during machining, thus meeting safety regulations.

[0032] As mentioned above, the machine is equipped with special straightening tools for correcting rim deformation or damage, as well as wrenches with adjustable positions for different types of rims, special wrenches for straightening rim edges, and various tools and accessories.

[0033] In addition, the machine can be combined with special tools for straightening and centering motorcycle brake discs, as well as devices for measuring deformation, to achieve perfect and comprehensive rim repair.

[0034] In other alternative embodiments of the invention, wherein the rim to be repaired comprises a central hub bolted to a rotating shaft of a motorcycle, and the means for fastening the machine comprises a tool coupling to a head via a fastening element introduced into a hole in the tool and coupled to the head, wherein the tool includes a coupling end in which a threaded fastening device is provided. Preferably, the threaded connection device comprises threaded holes suitably distributed in the coupling end, such that, in order to couple the rim to the tool, a hole in the hub is passed through by a threaded fastener coupled to the threaded hole, fastening the rim to the tool for straightening and / or machining the rim. Alternatively, threaded bolts suitably distributed in the coupling end are configured to pass through holes in the hub, the hub being fastened to the tool by nuts coupled to the threaded bolts.

[0035] In another embodiment of the invention, where the rim has a large width, such as that of a motorcycle with a very high engine displacement, the fastening device includes a tool coupling to the head via a fastening element, wherein a traction pin is intended to couple to the connection area of ​​the tool so as to move the rim coupled to the tool by dragging. An intermediate bushing coaxially coupling to the tool or head and / or an end bushing coupling to the intermediate bushing, tool, or head are part of such a fastening device; these bushings are coupled to each other to accommodate the width of the rim, fastening the hub on one side and securing the hub with a compression tool on the other side.

[0036] As described in the preceding lines, the main advantage of the machine for repairing wheel rims of the present invention is that it couples the wheel rim in a manner similar to how it is coupled to a motorcycle, regardless of the construction of its central hub, to ensure its concentricity relative to its axis of rotation after repair.

[0051] In the following detailed description, numerous specific details are illustrated by way of examples to provide a thorough understanding of the teachings. However, it will be apparent to those skilled in the art that these teachings can be implemented without these details.

[0052] This invention provides a machine for repairing motorcycle rims, which are primarily forged from a single piece of lightweight alloy material, such as, for example, high-strength aluminum. The rim includes a central hub, and subsequently, a wheel hub, which is intended to be rotatably coupled to the motorcycle chassis. Depending on the rim's fastening to the motorcycle, the wheel hub is provided with a pair of parallel bearings axially spaced relative to the rim's axis of rotation, adjusting the coupling to a through-axle in its front ring. In this way, the rim can rotate relative to the axle via the bearings; this hub configuration is most widely used in motorcycles. In an alternative configuration, the wheel hub includes a series of through-holes through which bolts are introduced, coupling to a rotating shaft structure arranged in the motorcycle, such that threaded fasteners or bolts couple the rim to said rotating shaft structure.

[0053] Considering the above situation, and according to Figure 1 As shown, the machine for repairing wheel rims according to the present invention includes a frame 1, which is provided with two vertical columns, namely vertical column 1A and vertical column 1B, connected by an intermediate base plate 14 and an upper crossbar 16. In a preferred embodiment, vertical column 1A, vertical column 1B, intermediate base plate 14 and upper crossbar 16 are formed of appropriately connected high-strength steel plates to form a rigid and stable frame 1.

[0054] The machine is equipped with a straightening device, which basically consists of a series of actuators and straightening tools that can be coupled to the actuators. These actuators and straightening tools are combined to address different deformations that may occur in the rim in order to straighten and center the rim.

[0055] As seen in Figures 1 to 3 In a preferred embodiment, the straightening device includes a first actuator 10 displaceable by a vertical column 1B, a second actuator 12 displaceable by being pushed by an upper crossbar 16 in a descending vertical direction, and a third actuator 13 for vertically pushing the displaceable part in an intermediate base plate 14.

[0056] The first actuator 10 is movable via the vertical column 1B of the frame 1, as seen in... Figures 1 to 3 The first actuator 10 is coupled to a block 10A movable via the vertical column 1B, wherein the first actuator 10 is coupled via a rack and pinion mechanism 32, which is actuated by a crank 63, which is readily coupled to the crank. The block 10A is configured to be locked when the first actuator 10 is positioned at the operating point.

[0057] The first actuator 10 also includes adjusting devices to adapt its position to the diameter of the rim to be repaired. For example, when the actuator is a piston that can be displaced within a cylinder, these adjusting devices include a round nut 11 that adjusts the displacement of the piston relative to the cylinder to position it appropriately according to the diameter of the rim. In this way, the first actuator 10 and the tool to which it can be coupled can be displaced longitudinally and laterally relative to the vertical column 1B to fit the size of the rim to be repaired, as seen in… Figure 11 and 12 Properly position the tools used for straightening tools 37 and 39.

[0058] Similarly, to move the second actuator 12 via the upper crossbar 16, a slider 58 (not shown) may be provided, to which the second actuator 12 may be coupled, wherein the slider 58 may be locked in the upper crossbar 16 to secure the second actuator 12 in a specific position. Likewise, the second actuator 12 may be movable relative to the slider 58 in a direction perpendicular to the upper crossbar 16 to better adjust to the size of the rim to be repaired and / or the position where vertical working pressure must be applied.

[0059] The third actuator 13 can be freely moved via the lower part 14A of the intermediate base plate 14 so as to be conveniently positioned in the working position relative to the rim.

[0060] In a preferred embodiment, actuators 10, 12, and 13 are hydraulic actuators, which are ideal for applying high compressive loads, such as those required to straighten a wheel rim. Therefore, the machine includes all suitable means for accumulating, controlling, and distributing fluid to enable actuators 10, 12, and 13 to function properly. However, as those skilled in the art will recognize, the use of other types of actuators, such as pneumatic or electric actuators, is also within the scope of this invention.

[0061] As seen in Figure 1 and Figure 2 The machine includes a pressure distributor 17 with an open and close valve 19 and a safety valve. The distributor 17 is supplied with hydraulic pressure by a hydraulic pump 9 at two speeds, a faster speed for approach pressure and another for high working pressure. The hydraulic system is connected by flexible, thermostatic, high-pressure hoses 20, with the hose length required for each device. The pressure distributor 17 is integrated with a pressure gauge 18.

[0062] It is important to note that the straightening tool, which will be described in detail later, is intended to be coupled to the first actuator 10, the second actuator 12, and the third actuator 13.

[0063] like Figures 1 to 3As shown, the machine includes a vertical support rod 8, which is coupled to the upper crossbar 16 via a block that is fixedly coupled to the upper crossbar 16. The vertical support rod 8 is vertically movable within the block and can be secured in a suitable position, thus allowing its height to be adjusted relative to the upper crossbar 15. The vertical support rod 8 is configured to support the rim in conjunction with a fastening device coupled to the machine, as will be seen later.

[0064] In addition, as seen in Figures 1 to 6 The machine for repairing wheel rims of the present invention is provided with a head base 3 that can be coupled to an intermediate base plate 14, which is configured to rotatably accommodate a portion of a head 2, which is configured to rotate freely relative to the main axis or to be rotated by a transmission device.

[0065] As described above, since the head 2 is a rotating body, the rotation is relative to the main axis (the instantaneous axis of rotation of the head), and when the rim is coupled to the head, the main axis coincides with the axis of rotation of the rim.

[0066] In a preferred embodiment, the head base 3 includes a flange end (not shown) through which the head base 3 is fixed to the intermediate base plate 4, and a cylindrical segment 3A that protrudes from the flange end and passes through the intermediate base plate 4. The head base 3 is provided with a through hole (not shown) and is configured for rotational coupling of the head rod 2B of the head 2. Suitable means for rotating the head rod 2B and thus allowing the head 2 to rotate freely are arranged in the hole of the head base 3, such as a self-lubricating bushing, a friction roller bearing, and / or preferably, a bearing to which the head rod 2B is coupled, wherein the bearing may be of the type supporting axial, radial, or mixed loads.

[0067] In addition, such as Figure 5 As shown, the head 2 includes a coupling body 2A configured for coupling different tools that form part of a fastening device. A rim is coupled to the machine via this fastening device. For this purpose, a hole 2A1 for coupling the tools is arranged in the coupling body 2B. Preferably, this hole 2A1 is a threaded hole for threaded fastening of the tools in the fastening device. The head rod 2B extends coaxially from the coupling body 2A and, as described above, is introduced into a hole in the head base 3. One end of the head rod 2B, opposite to the coupling body 2A, protrudes from a cylindrical section 3A of the head base 3 and is configured to couple elements for actuating the transmission mechanism. Figure 6 As shown, the actuating element takes the form of a driven pulley 75, which is actuated by a transmission belt that transmits the motion of a drive pulley 74 connected to the output shaft of a motor reducer 28 that can be mounted in the intermediate base plate 14. The motor reducer 28, drive pulley 74, driven pulley 75, and the belt connecting the drive pulley 74 and driven pulley 75 form a transmission configuration that drives the head 2 to rotate. Those skilled in the art will recognize that variations of the transmission configuration are within the scope of this invention.

[0068] It is important to note that the transmission mechanism must allow the head 2 to rotate freely, which is necessary for rim repair. In a preferred embodiment, the drive pulley 74 includes bearings, one of which is a "freewheel," for example... The company releases bearings in its products in which the inner and outer rings of the freewheel bearing rotate freely in their relative directions, such as clockwise, and are locked to move relative to each other in opposite directions. This allows motion to be transmitted from the shaft coupled to the freewheel bearing, in which case the shaft of the motor reducer 28 can also achieve free rotational motion of the head 2.

[0069] To facilitate coupling of the tool to the head 2, the latter's rotation can be locked by a locking device 4 located in the intermediate base plate 14. Figure 5 In the illustrated embodiment, the locking device 4 includes a locking base 4A that can be coupled to the intermediate base plate 14 by means of, for example, bolts. The locking base 4A includes a hole through which a pin 4B is displaceable and removably coupled to the head 2. The hole includes a hole (not shown) for inserting the pin 4B. This type of locking device is known in the prior art, and variations thereof are also within the scope of this invention.

[0070] As previously mentioned, the machine is equipped with a fastening device, which is formed by several embodiments of tools prepared for fastening the rim in the machine in order to perform maintenance work.

[0071] Figure 1 , 2 Figures 11 to 13 show a fastening tool 6 that can be coupled to the head 2 and the vertical support rod 8. The fastening tool 6 includes a base 6A from which a rod 6A1, configured to be coupled to the head 2, extends. Specifically, the rod 6A1 includes a threaded portion in a threaded hole 2A1 prepared for coupling to the head 2. A rod 6B, extending from the base 6A opposite to the rod 6A1, is configured to be coupled to the vertical support rod 8 at an end opposite the base 6A.

[0072] To achieve coupling between rod 6B and vertical support rod 8, the latter includes a housing at a connecting end on the opposite side from the block to where it can be coupled to the upper crossbar 16, wherein the lead end 6B1 of rod 6B is rotatably coupled. In a preferred embodiment, a bearing is coupled within the housing, and the lead end 6B1 of the fastening tool 6 is inserted into the inner ring of the bearing in a mating manner. Thus, with the fastening tool 6 coupled to the head 2, when the vertical support rod 8 is lowered, the bearing is coupled within rod 6B, and this coupling between rod 6B and vertical support rod 8 is supported by the coupling device 7.

[0073] In a preferred embodiment, the coupling device 7 includes a nut that moves in the threaded portion of the inlet end 6B1 against the end of the vertical support rod 8 to generate compression through the rod 6B supporting the fastening tool 6.

[0074] As seen in Figure 2 and Figure 12 When the rim is installed in the machine, the rim is rotatably coupled to the fastening device 6 via the hub. In particular, rod 6B is coupled to the bearing of the rim hub.

[0075] As seen in Figures 1 to 3 The machine for motorcycle repair of the present invention includes a processing device that is movably mounted in a vertical column 1A of a frame 2.

[0076] The machining apparatus includes a support 51 coupled via a rack and pinion mechanism to a guide support displaceable by the vertical column 1A, which is crank-actuated and locked at a desired point. The machining apparatus also includes a tool carrier 52 movable relative to the support 51 via a crank, and a rotating turret connected to a cutting tool 53 configured to remove material from the rim during machining coupling.

[0077] In addition, as seen in Figure 3 and Figure 4 The fastening device includes a chuck 29 that can be coupled to the head 2 and a compression tool 54 that can be coupled to the vertical support rod 8 and configured to couple the rim hub. The chuck 29 functions similarly to a conventional chuck and includes an end that is arranged, for example, to be threadedly coupled into a hole 2A1 in the head 2.

[0078] The compression tool 54 includes a sleeve 54A, which is coaxially coupled to and adjustable relative to the vertical support rod 8, and a pivot point 54B, which is coaxially coupled to the sleeve 54A and configured to couple to the hub of the rim.

[0079] As seen in Figure 1 and Figure 2 The connecting end of the vertical support rod 8 is configured for coupling the sleeve 54A. In a preferred embodiment, the connecting end includes an external thread coupled to the internal thread of the sleeve 54A. The handle 54A1 coupled to the sleeve 54A facilitates the coupling and / or adjustment of the compression tool 54 within the vertical support rod 8.

[0080] Regarding the pivot point 54B coupled to the sleeve 54, it includes a rotating tapered portion intended to accommodate and press against the rim hub. Thus, when the vertical support rod 8 descends together with the compression tool 54, the rim is secured against the chuck 29 via the hub.

[0081] The adapter 30, coupled to the chuck 29, engages with the bearing of the hub on one side, while on the other side, the hub is secured by pressure applied to the pivot point 54B of the compression tool 54, as seen in... Figure 4 In this way, the rim is locked in rotation relative to the head 2, and when the head 2 is actuated by the transmission device, the rim rotates, thus enabling it to be processed by the processing device.

[0082] Furthermore, as shown at the beginning of this section, in some motorcycle rims, for example... In the brand's rims, the hub is fixed to a structure with a motorcycle's axis of rotation using bolts. These bolts pass through through holes in the hub to secure it to the structure with the axis of rotation.

[0083] Therefore, in order to couple these types of rims, such as Figure 7 and 8 As shown, the fastening device includes a tool 36 that can be coupled to the head 2 via a fastening element 57, which is intended to be introduced into a hole 36A (not shown) arranged in the tool 36 and coupled to a hole 2A1 in the head 2. The tool 36 includes an end 36B configured to couple a rim hub, wherein a threaded fastening device 36C is provided. In a preferred embodiment, the threaded fastening device 36C is a threaded hole to which a fastener 360 can be coupled to support the rim hub against the end 36B. Alternatively, the fastener 360 is arranged at the end 36B and supports the hub using a nut or the like.

[0084] Some motorcycle rims are wider than normal rims, making the height of the head 2 insufficient to couple these types of rims into the machine. Therefore, as seen in... Figure 9 and Figure 10 The fastening device includes a tool 69 that can be coupled to the head 2 via a fastening element 57 coupled in a hole 2A1 in the head 2, the tool 69 including a connection region 69A intended for coupling a traction pin 68.

[0085] As seen in Figure 9 Tool 69 includes a traction pin 68 via its coupling radial groove 69A, which in turn includes a weakened area to ensure the safety of the rim during machining.

[0086] In this embodiment, the fastening device includes an intermediate bushing 71 coaxially coupled to the tool 69 or the head 2 and an end bushing 72 coaxially coupled to the intermediate bushing 71 or the head 2, which includes a hemispherical end 72A configured to couple the rim hub.

[0087] When using the combination of tool 69, intermediate bushing 71, and / or end bushing 72, the end bushing 72 couples the hub to one side, while the rim is secured on the other side using fastening tool 54. With this configuration of the fastening device, rims with a large width can be straightened and / or machined in the rim repair machine of the present invention.

[0088] Figure 11 and Figure 12 Straightening tools 24, 28, 37, and 39, which can be coupled to the first actuator 10, are shown and can be used to straighten wheel rims. Those skilled in the art will understand that different tools can be used in the machine to repair wheel rims.
