Detailed Implementation

[0027] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0030] It should be noted that the turbine disk of an aircraft engine is one of the core power components of an aircraft engine. Its performance directly determines the engine's efficiency, reliability, and lifespan, and thus affects the aircraft's performance and safety.

[0031] The manufacturing process of aero-engine bladed disks involves multiple processing steps, with grinding and polishing being one of the key processes. Precision grinding and polishing removes machining defects from the blades on the disk.

[0032] With the development of the manufacturing industry, people have increasingly higher requirements for the precision of blades, and traditional manual polishing operations are gradually being replaced by industrial robots. Among them, the polishing belt is a ring-shaped belt structure, whose inner belt surface is used to cooperate with the corresponding drive wheel to form a belt drive structure, thereby realizing rotation and polishing the workpiece through the outer belt surface.

[0033] The blades on different types of aero-engine bladed disks vary in size. Some special bladed disks have small blade spacing and large blade twist angles. Conventional polishing machines are large and incompatible with these special bladed disks. When polishing with a conventional polishing machine, the polishing machine will interfere with the bladed disk, which can easily affect the quality of the workpiece.

[0034] Understandably, the cost of processing equipment is relatively high, while the number of special impellers is relatively small and the variety is large. Given this situation, if a separate polishing machine were configured for each type of special impeller, the overall processing cost would be very high.

[0035] To solve the above problems, refer to Figure 1 As shown in the figure, this utility model embodiment provides a polishing machine. The polishing machine includes a base 10, a connecting member 20, a drive wheel 30, an extension arm 40, a driven wheel 421, and a polishing belt 50.

[0036] The base 10 serves as the base for the polishing machine. On the one hand, it can be used to mount other components; on the other hand, it can be connected to the corresponding driver to adjust the polishing position and angle.

[0037] The base 10 is provided with a rotatable connector 20. Those skilled in the art can configure the rotatability of the connector 20 and the base 10 according to actual needs. For example, a second driver 15 is provided on the base 10, and the connector 20 is connected to the drive end of the second driver 15, driving the connector 20 to rotate via the second driver 15. Alternatively, the connector 20 can be connected to the base 10 only via a bearing or similar structure, and a corresponding driver can be provided outside the polishing machine to drive the rotation of the connector 20.

[0038] The driving pulley 30 and driven pulley 421 work together with the polishing belt 50 to form a belt drive structure. Thus, the driving pulley 30 drives the polishing belt 50 and driven pulley 421 to rotate, thereby achieving the polishing of workpieces such as impellers. In this embodiment of the invention, each polishing machine is equipped with only one driving pulley 30 and one driven pulley 421. Of course, the polishing machine can be equipped with multiple spare driving pulleys 30 and driven pulleys 421 of the same or different sizes.

[0039] The drive wheel 30 and the connector 20 are detachably connected. Those skilled in the art can configure the detachable connection method between the drive wheel 30 and the connector 20 according to actual needs, such as snap-fit ​​or threaded connection.

[0040] Because it is a detachable connection structure, therefore, refer to Figure 2 As shown, when the polishing machine is dealing with special types of workpieces, and the width of the polishing belt 50 used is relatively too wide or too narrow, it can improve its compatibility by disassembling the current drive wheel 30 and replacing it with a new drive wheel 30.

[0041] Thus, compared to disassembling, assembling, and debugging a brand-new polishing machine, replacing individual parts is less difficult and time-consuming, improving overall production efficiency. At the same time, the cost of individual parts is relatively low, reducing production costs. Finally, the polishing machine can be specifically configured with a polishing belt 50, improving the quality of finished workpieces.

[0042] After the drive wheel 30 is assembled and connected to the connector 20, the drive wheel 30 can be rotated through the drive wheel 20, thereby achieving polishing.

[0043] The extension arm 40 is an important component of the polishing machine described in this utility model. Conventional polishing machines often only have the main and driven wheels on the machine body to achieve polishing. This makes it difficult for conventional polishing machines to extend the polishing belt 50 between the blades for polishing when dealing with special impellers with small blade spacing and large blade torsion angles. Either some parts cannot be polished, or the machine interferes with the workpiece, which will affect the quality of the workpiece and may even damage the workpiece and increase processing costs.

[0044] Therefore, in this embodiment of the invention, an extension arm 40 is provided so that the relatively longer and smaller extension arm 40 can be inserted between the blades to perform polishing operations.

[0045] Specifically, the extension arm 40 includes a first arm end 41 and a second arm end 42 disposed at both ends along its length. The first arm end 41 is detachably connected to the machine base 10. Those skilled in the art can configure the detachable connection between the first arm end 41 and the machine base 10 according to actual needs, such as snap-fit ​​or threaded connection. The second arm end 42 is provided with a rotatable driven wheel 421. Preferably, the driven wheel 421 and the second end are connected by a pin. It is understood that during processing, the driven wheel 421 rotates by the transmission of the polishing belt 50.

[0046] Because it is a detachable connection structure, therefore, refer to Figure 2As shown, when the polishing machine is dealing with special types of workpieces, and the width of the polishing belt 50 used is relatively too wide or too narrow, the current extension arm 40 and driven wheel 421 can be disassembled and replaced with new extension arm 40 and driven wheel 421, so that the polishing machine can be compatible with different types of workpieces and the compatibility is improved.

[0047] In addition to adjusting the width of the polishing belt 50, the extension arm 40 of different lengths can also be adjusted. Thus, when dealing with some special large-sized blades, the extension arm 40 can be used to send the polishing belt 50 to a deeper depth for polishing, thereby improving the quality of the finished workpiece.

[0048] The polishing belt 50 is set on the driving wheel 30 and the driven wheel 421. It can be understood that the polishing belt 50 is a ring-shaped belt structure that is directly sleeved on the driving wheel 30 and the driven wheel 421.

[0049] Reference Figure 2 As shown, during polishing, the connecting piece 20 and the drive wheel 30 rotate, which in turn drives the polishing belt 50 and the driven wheel 421 to rotate, thus polishing the blades. When using the polishing machine to complete a small batch of special-type bladed disks, and the next batch of bladed disks requires a wider or narrower polishing belt 50, it is not necessary to replace the entire polishing machine. Instead, only one part needs to be selected: a new polishing belt 50, drive wheel 30, extension arm 40, and driven wheel 421. On the other hand, the polishing belt 50, drive wheel 30, extension arm 40, and driven wheel 421 on the polishing machine need to be removed. Then, the new parts are installed sequentially on the machine base 10, thus completing the adaptation and adjustment of the polishing machine to the new bladed disks.

[0050] The polishing machine described in this utility model utilizes a detachable drive wheel 30 and an extension arm 40. When faced with different types of impellers, the machine can be adapted to new impellers by simply changing the extension arm 40 and the drive wheel 30, improving machine compatibility and convenience. With the assistance of the extension arm 40, the polishing machine can reach between closely spaced blades for polishing, avoiding processing dead angles and interference, effectively improving processing quality and reducing processing costs.

[0051] Reference Figure 3 and Figure 4 As shown, in some embodiments of the polishing machine of this utility model, the base 10 is provided with a plurality of first connecting holes 121, which are evenly spaced along the length direction of the extension arm 40. The first arm end 41 is provided with a plurality of second connecting holes 411, which are evenly spaced along the length direction of the extension arm 40. A first fastener 61 is provided in the first connecting holes 121 and the second connecting holes 411, and the base 10 and the extension arm 40 are detachably connected by the first fastener 61.

[0052] By setting this structure, the base 10 and the extension arm 40 can be detachably connected using the first fastener 61 and the corresponding connection hole, and the structural connection is stable and reliable.

[0053] Preferably, the first fastener 61 is a bolt, and corresponding threads are provided on the hole wall surface of the first connecting hole 121 and / or the second connecting hole 411 to achieve a threaded connection. Alternatively, a nut may be additionally configured to mate with the bolt.

[0054] Reference Figure 3 and Figure 4 As shown, in some embodiments of the polishing machine of this utility model, the base 10 is provided with a first locking part 122. The first arm end 41 is provided with a second locking part 412, and the second locking part 412 is locked and connected to the first locking part 122.

[0055] Those skilled in the art can configure the specific structure of the first snap-fit ​​portion 122 and the second snap-fit ​​portion 412 according to actual needs, for example, one can be configured as a protrusion and the other as a groove. In this embodiment of the present invention, the first snap-fit ​​portion 122 is configured as a snap-fit ​​groove and the second snap-fit ​​portion 412 is configured as a snap-fit ​​protrusion to achieve snap-fit.

[0056] This structure facilitates the positioning of the extension arm 40 and the base 10, enabling quick assembly and disassembly. Combined with the connecting holes and fasteners, it further enhances the machine's stability and reliability.

[0057] Referring to Figure 2, in some embodiments of the polishing machine of this utility model, the base 10 is provided with a transition connecting plate, and the transition connecting plate is provided with a transition connecting part, which is detachably connected to the extension arm 40. That is, the first connecting hole 121 and the first snap-fit ​​part 122 are both provided on the transition connecting part.

[0058] The transition connection is designed with a gradually decreasing size. Specifically, the size of the transition connection gradually decreases along the direction from the transition connection plate toward the extension arm 40. By setting this structure to accommodate the small-sized extension arm 40, the possibility of interference between the polishing machine and the workpiece is further reduced.

[0059] In automated polishing operations using industrial robots, the ability to automatically change the polishing belt 50 is crucial for achieving efficient polishing. When the polishing machine and the changer work together to change the belt, especially when dealing with the uniquely soft and narrow polishing belt 50, belt slippage is a common problem, resulting in a low success rate for replacement.

[0060] To solve the above problems, refer to Figure 1 , Figure 5 and Figure 6As shown, in some embodiments of the polishing machine of this utility model, the base 10 includes a first sub-base 11 and a second sub-base 12. The first arm end 41 is disposed on the first sub-base 11, that is, the transition connecting plate and the extension arm 40 are both disposed on the first sub-base 11. The connecting member 20 is disposed on the second sub-base 12, that is, the drive wheel 30 is disposed on the second sub-base 12.

[0061] The second sub-seat 12 is configured to move relative to the first sub-seat 11 along the length of the extension arm 40. Those skilled in the art can configure the movement of the second sub-seat 12 according to actual needs. For example, it can be driven by a driver, or manually adjusted by using components such as guide rails or clamps.

[0062] By designing this structure, when the polishing machine and the belt changer are used to change belts, the distance between the first bearing seat 11 and the second bearing seat 12 can be reduced, which also reduces the distance between the driving wheel 30 and the driven wheel 421. This allows the originally tensioned polishing belt 50 to be relaxed, thus easily achieving belt change. After the spare polishing belt 50 is transferred from the belt changer to the polishing machine, the distance between the first bearing seat 11 and the second bearing seat 12 is reset, thereby tensioning the polishing belt 50 for subsequent polishing operations.

[0063] Furthermore, refer to Figure 5 As shown, in some embodiments of the polishing machine of this utility model, the first sub-seat 11 is provided with a first driver 13, the driving end of the first driver 13 is connected to the second sub-seat 12, and the first driver 13 is used to drive the second sub-seat 12 to move along the length direction of the extension arm 40. Preferably, the first driver 13 is configured as a drive cylinder.

[0064] Furthermore, refer to Figure 5 As shown, in some embodiments of the polishing machine of this utility model, the first driver 13 is equipped with a displacement sensor 14. The displacement sensor 14 is used to detect the target moving distance, which is the moving distance of the second sub-seat 12 relative to the first sub-seat 11. The working principle of the displacement sensor 14 is prior art and will not be described in detail here. Preferably, the displacement sensor 14 is configured as a proximity switch.

[0065] By setting up a displacement sensor 14 to detect the target's movement distance, the machine can use this movement distance to indicate whether the polishing belt 50 has been successfully replaced. This effectively ensures the machine's safety and reliability.

[0066] Reference Figure 1 and Figure 5 As shown, in some embodiments of the polishing machine of this utility model, the first driver 13 is disposed inside the first sub-seat 11 in order to reduce the possibility of dust generated during polishing interfering with the first driver 13 and extend the service life of the machine.

[0067] Reference Figure 1 and Figure 2 As shown, in some embodiments of the polishing machine of this utility model, the diameter of the driven wheel 421 is set to be no greater than the diameter of the driving wheel 30.

[0068] To accommodate special blade models, the driven wheel 421 also needs to be relatively small in size so that it can be inserted between the blades by the extension arm 40 for polishing operations, adapting to narrow spaces and improving the quality of finished workpieces.

[0069] The structure of the large-size drive wheel 30 can effectively reduce the bending stress on the polishing belt 50, extend the service life of the polishing belt 50, reduce the speed fluctuation of the polishing belt 50, improve transmission stability, disperse the tension of the polishing belt 50, reduce local slippage, and improve transmission efficiency.

[0070] Reference Figure 1 and Figure 2 As shown, in some embodiments of the polishing machine of this utility model, the base 10 is provided with an angle adjusting wheel 123, the wheel surface of which abuts against the polishing surface of the polishing belt 50. Along the length direction of the extension arm 40, the angle adjusting wheel 123 is disposed between the driving wheel 30 and the driven wheel 421.

[0071] The polishing belt 50 is driven by the drive wheel 30 and driven wheel 421 of the polishing machine, which can be understood as a belt drive. Therefore, it can be divided into a tight side and a slack side. When the drive wheel 30 rotates, the tight side actively pulls the polishing belt 50 forward, responsible for transmitting power; while the slack side is on the opposite side of the pull of the drive wheel 30, this part is not taut, and can achieve buffer protection. The polishing surface is the side of the polishing belt 50 that is used to contact the workpiece to achieve polishing.

[0072] When polishing the blades on an impeller, the required tilt angle of the polishing belt 50 on the polishing machine varies depending on the impeller model. The tilt angle can be understood as the relative angle between a certain part of the tight side and the slack side.

[0073] By setting the angle adjustment wheel 123, the slack or tight side of the polishing belt 50 can be restricted, thereby adjusting the tilt angle between the slack and tight sides of the polishing belt 50 to adapt to the processing requirements of various workpieces and further improve the machine's compatibility.

[0074] Those skilled in the art can fix the angle adjusting wheel 123 to the first sub-base 11 to achieve processing for a specific tilt angle. Alternatively, a structure such as a strip hole can be provided so that the angle adjusting wheel 123 can be adjusted in its relative position to the first sub-base 11, further improving compatibility.

[0075] Reference Figure 7 As shown, in some embodiments of the polishing machine of this utility model, the drive wheel 30 is provided with a first countersunk hole 31 along its own axial direction, the bottom of the first countersunk hole 31 is provided with a second countersunk hole 32, and the bottom of the second countersunk hole 32 is provided with a first shaft through hole 33. The connecting member 20 includes a first connecting component 21 and a second connecting component 22.

[0076] The first connecting component 21 is disposed within the second recessed hole 32, which has a tapered through hole 211 and a third connecting hole 212. The tapered through hole 211 connects to the first shaft through hole 33, and its diameter gradually decreases along the direction close to the machine base 10. Multiple third connecting holes 212 are provided, arranged sequentially along the circumference of the tapered through hole 211.

[0077] The second connecting component 22 is provided with a second shaft through hole 221, a tapered connecting protrusion 222, and an abutting boss 223. The second shaft through hole 221 connects the tapered through hole 211 and the first shaft through hole 33. The tapered connecting protrusion 222 is disposed in the second countersunk hole 32 and is engaged with the tapered through hole 211. The abutting boss 223 is disposed in the first countersunk hole 31 and abuts against the bottom surface of the first countersunk hole 31. The abutting boss 223 is provided with a plurality of fourth connecting holes 224, which are arranged sequentially along the circumference of the second shaft through hole 221.

[0078] The second sub-seat 12 is provided with a second driver 15, the driving end of which passes through the first shaft through hole 33, the tapered through hole 211, and the second shaft through hole 221. The driving end of the second driver 15 is configured to be rotatable. Preferably, the second driver 15 is configured as a drive motor.

[0079] The second fastener 62 is provided in the third connection hole 212 and the fourth connection hole 224, and the second driver 15, the connector 20 and the drive wheel 30 are detachably connected by the second fastener 62.

[0080] The drive end of the drive motor, the drive wheel 30, and the connecting piece 20 achieve rotational transmission through a key.

[0081] During installation, the tapered through-hole 211 and the tapered connecting protrusion 222 cooperate to allow the first connecting component 21 to abut against the inner wall of the second countersunk hole 32. The second connecting component 22 abuts against the driving end of the second driver 15 and the first connecting component 21, respectively, achieving radial limiting. Simultaneously, the second fastener 62 and the abutting protrusion 223 provide axial limiting for the drive wheel 30. The overall structure is stable, reliable, and easy to assemble and disassemble.

[0082] Reference Figure 1 and Figure 5As shown, in some embodiments of the polishing machine of this utility model, a dust cover is provided outside the second driver 15 to reduce the possibility of dust generated during polishing interfering with the second driver 15 and extend the service life of the machine.

[0083] On the other hand, this utility model embodiment also provides a polishing device, including the polishing machine described in any of the above embodiments. Since the polishing device of this utility model includes the polishing machine described in the above embodiments, it also possesses all the beneficial effects described herein, and will not be repeated here.

[0084] In some embodiments, the polishing equipment described in this utility model further includes a robotic arm (not shown). The robotic arm is used to drive the polishing machine to move in space, including moving and rotating, thereby polishing the impeller, and to replace the polishing belt 50 in conjunction with a changer when the polishing belt 50 is worn. In some other embodiments, other drives, such as a combination of a three-axis drive and a rotary actuator, can be used to replace the robotic arm for driving.

[0085] Furthermore, in some embodiments, the drive end of the robotic arm is detachably connected to the polishing machine. This allows a single robotic arm to be adapted to different polishing machines, enabling the replacement of different models of polishing machines and the performance of corresponding maintenance tasks as needed.

[0086] Those skilled in the art can configure a detachable connection method between the two according to actual needs, including but not limited to snap-fit, threaded connection, etc. In the embodiments of this utility model, a threaded connection is preferred.

[0087] In some embodiments, the polishing equipment described in this invention also includes a vision detector (not shown). The vision detector is prior art, and its specific principle will not be elaborated further. Those skilled in the art can configure different types of vision detectors, such as various types of industrial cameras, according to actual needs.

[0088] In this design, both the drive wheel 30 and the driven wheel 421 of the polishing machine are positioned within the detection range of the vision detector. The vision detector monitors the drive wheel 30 and the driven wheel 421 to determine the status of the corresponding polishing belt 50. For example, when the polishing machine is used in conjunction with the belt changer, the vision detector monitors the drive wheel 30 and the driven wheel 421 to determine whether the polishing belt 50 has been replaced correctly. This structure, combined with the displacement sensor 14, provides dual protection, further ensuring the automatic replacement of the polishing belt 50 and reducing polishing accidents caused by incorrect belt replacement, thus improving the safety of automated operations.

[0089] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0090] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0091] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
