Description

Technical Field

[0001] The present disclosure relates to a blade coating fixture adapter. Background Art

[0002] The turbine blades of a turbine are subjected to high temperatures and high pressures during operation. To prevent high-temperature corrosion and extend their service life, thermal barrier coatings are sprayed (or applied) on the blades.

[0003] To spray the blade coating, a blade coating fixture is designed. This fixture is mounted on the rotary table of the coating spraying system, and the blade is clamped on the blade coating fixture. The blade coating fixture rotates with the rotary table while the coating spraying system sprays the blade.

[0004] Current heavy-duty blade coating fixtures are typically designed as one-piece structures, requiring assembly and disassembly on a rotating worktable for each clamping operation. This design makes assembly and disassembly cumbersome and time-consuming, significantly impacting clamping accuracy. Furthermore, due to the heavy weight of both the blade and the fixture, the assembly and disassembly process can easily cause wear at the joints on the worktable, reducing their lifespan and compromising clamping accuracy.

[0005] The present disclosure provides a blade coating fixture adapter device, which at least partially solves the shortcomings of the prior art. Summary of the Invention

[0006] The technical problem to be solved by the present disclosure is to provide a blade coating fixture adapter device that can reduce the wear on the rotary worktable while also ensuring clamping accuracy.

[0007] In order to solve the above technical problems, according to the first aspect of the present disclosure, a blade coating fixture adapter is provided for connecting the blade coating fixture to a rotary worktable, characterized in that it includes: a lower connecting component for fixedly connecting to the upper surface of the rotary worktable, so that the central axis of the lower connecting component is coaxially arranged with the rotation axis of the rotary worktable, and the lower connecting component has a first center positioning structure extending along the central axis; an upper connecting component for fixedly connecting to the lower surface of the base of the blade coating fixture, and the upper connecting component has a second center positioning structure for cooperating with the first center positioning structure; and a support component, which is arranged between the rotary worktable and the base of the blade coating fixture and supports the base of the blade coating fixture.

[0008] In the present disclosure, the blade coating fixture is centrally positioned relative to the rotational axis of the rotary table through the cooperation of a first centering structure on the lower connecting assembly and a second centering structure on the upper connecting assembly. Therefore, when replacing the blade coating fixture, only the lower and upper connecting assemblies of the adapter need to be disassembled and installed, reducing wear on the rotary table while ensuring clamping accuracy. Furthermore, because the blade coating fixture and the blade clamped thereto are supported by the support assembly, the adapter's positioning structure / function is separated from its support structure / function, further improving clamping accuracy.

[0009] Further, according to an embodiment of the present disclosure, the lower connecting assembly includes: a lower connecting plate for fixedly connecting to the upper surface of the rotating worktable; a lower connecting sleeve for fixedly connecting to the lower connecting plate; and a connecting shaft, the lower end of which is inserted into the lower connecting sleeve, and the outer surface of the upper end of the connecting shaft forms the first center positioning structure, wherein the lower connecting plate, the lower connecting sleeve and the connecting shaft are arranged along the central axis of the lower connecting assembly; the upper connecting assembly includes: an upper connecting plate for fixedly connecting to the lower surface of the base of the blade coating fixture; and an upper connecting sleeve for fixedly connecting to the upper connecting plate, and the inner surface of the upper connecting sleeve cooperates with the upper end of the connecting shaft to form the second center positioning structure.

[0010] In the present disclosure, the lower connecting assembly and the upper connecting assembly both include a connecting plate and a connecting sleeve, which are convenient for processing. Moreover, since the lower end and the upper end of the connecting shaft are respectively connected to the lower connecting sleeve and the upper connecting sleeve, the upper and lower connecting plates and the connecting sleeve can be processed into the same structure, and the two ends of the connecting shaft can also be designed into the same structure, thereby providing interchangeability of related components.

[0011] Further, according to one embodiment of the present disclosure, the lower connecting sleeve includes a lower connecting sleeve body and a lower connecting sleeve flange arranged at the lower end of the lower connecting sleeve body, and the lower connecting sleeve flange is connected to the lower connecting plate; the upper connecting sleeve includes an upper connecting sleeve body and an upper connecting sleeve flange arranged at the upper end of the upper connecting sleeve body, and the upper connecting sleeve flange is connected to the upper connecting plate.

[0012] In the present disclosure, by providing a lower connecting sleeve flange and an upper connecting sleeve flange, it is easier to fix the lower connecting sleeve and the upper connecting sleeve.

[0013] Further, according to one embodiment of the present disclosure, the upper end and the lower end of the connecting shaft respectively have a shaft drive key extending along the axial direction; the inner surfaces of the upper connecting sleeve and the lower connecting sleeve are respectively provided with a sleeve drive groove extending along the axial direction, and the sleeve drive groove cooperates with the shaft drive key so that the upper connecting sleeve and the lower connecting sleeve are positioned circumferentially relative to the connecting shaft.

[0014] In the present disclosure, the circumferential positioning and synchronous movement of the upper and lower connecting sleeves are achieved by cooperating with the shaft drive key on the connecting shaft and the sleeve drive grooves on the upper and lower connecting sleeves, so that when the rotary worktable rotates, the adapter device can drive the blade coating fixture installed thereon to move synchronously.

[0015] Further, according to an embodiment of the present disclosure, shaft connecting holes are respectively provided at the parts of the connecting shaft that cooperate with the upper connecting sleeve and the lower connecting sleeve 12; sleeve connecting holes are respectively provided on the upper connecting sleeve and the lower connecting sleeve, and the upper connecting sleeve and the lower connecting sleeve are fastened to the connecting shaft by connecting screws that cooperate with the sleeve connecting holes and the shaft connecting holes.

[0016] In the present disclosure, the upper connecting sleeve and the lower connecting sleeve are fastened to the connecting shaft by the fastening action of the connecting screws to avoid relative movement, so that the structure of the entire blade coating fixture adapter is more stable, thereby better ensuring the clamping accuracy.

[0017] Further, according to an embodiment of the present disclosure, the support assembly includes a support sleeve, which is arranged around the lower connecting assembly and the upper connecting assembly, and a side wall opening is provided on the support sleeve, so that the operator can operate the connecting screw through the side wall opening.

[0018] In the present disclosure, the support sleeve is arranged around the lower connecting assembly and the upper connecting assembly, which can provide more stable and reliable support. In addition, by arranging the side wall opening on the support sleeve, it is convenient to operate the connecting screws.

[0019] Further, according to an embodiment of the present disclosure, the support assembly includes: a support plate, which is used to be fixedly connected to the upper surface of the rotating worktable; a support sleeve, which is fixedly connected to the support plate and is arranged around the lower connecting assembly and the upper connecting assembly, and has an upper end surface of the support sleeve, and the upper end surface of the support sleeve supports the lower surface of the base of the blade coating fixture or supports the lower surface of the lower connecting plate.

[0020] In the present disclosure, the support sleeve is arranged around the lower connecting assembly and the upper connecting assembly, which can provide more stable and reliable support, and by providing a support plate, the support assembly is easy to install and fix.

[0021] Furthermore, according to one embodiment of the present disclosure, reference position marks are respectively provided on the connecting shaft and the upper connecting sleeve. By connecting the upper connecting sleeve to the connecting shaft with the reference position marks aligned, the blade coating fixture connected to the lower connecting assembly is located at a determined reference position in the circumferential direction relative to the rotary worktable.

[0022] In the present disclosure, by setting a reference position mark, it is possible to ensure that the blade coating fixture is located at a certain reference position in the circumferential direction relative to the rotary worktable, thereby ensuring that the coating operation on the blade clamped on the blade coating fixture is performed from a predetermined initial position.

[0023] Further, according to an embodiment of the present disclosure, there is a gap between the upper end surface of the connecting shaft of the connecting shaft and the lower surface of the upper connecting plate.

[0024] In the present disclosure, by forming the gap, the upper end surface of the connecting shaft can be prevented from contacting the lower surface of the upper connecting plate, thereby better avoiding the pressure from the blade coating fixture, thereby better ensuring the clamping accuracy.

[0025] Furthermore, according to one embodiment of the present disclosure, a through central through hole is provided on the lower connecting assembly, the upper connecting assembly and the supporting assembly, which are coaxially arranged with the central through hole on the rotating workbench and the central through hole on the base of the blade coating fixture, and together constitute a cooling channel for providing cooling airflow to the blade clamped on the blade coating fixture.

[0026] In the present disclosure, by providing a cooling channel, it is convenient to control the temperature of the blade when coating the thermal barrier coating on the blade. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0035] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form.

[0036] Figure 1 is a schematic diagram of the three-dimensional structure of the blade coating fixture adapter according to an embodiment of the present disclosure, Figure 2 yes Figure 1 The cross-sectional structural diagram of the blade coating fixture adapter is shown.

[0037] See also Figure 1 In an embodiment of the present disclosure, the blade coating fixture adapter 100 of the present disclosure is used to connect the blade coating fixture to the rotary table 4. Figure 1 and 2As can be seen in the figure, the blade coating fixture adapter 100 is installed between the rotating worktable 4 and the base 5 of the blade coating fixture. The blade coating fixture adapter 100 includes: a lower connecting component 10, an upper connecting component 20 and a support component 30. Among them, the lower connecting component 10 is used to be fixedly connected to the upper surface of the rotating worktable 4, so that the central axis of the lower connecting component 10 is coaxially arranged with the rotation axis of the rotating worktable 4. The lower connecting component 10 has a first center positioning structure (the outer surface of the upper end of the connecting shaft 13) extending along the central axis. The upper connecting component 20 is used to be fixedly connected to the lower surface of the base 5 of the blade coating fixture. The upper connecting component 20 has a second center positioning structure (the inner surface of the upper connecting sleeve 22) for cooperating with the first center positioning structure; and the support component 30 is arranged between the rotating worktable 4 and the base 5 of the blade coating fixture and supports the base 5 of the blade coating fixture.

[0038] In this embodiment, the blade coating fixture is centrally positioned relative to the rotation axis of the rotary table 4 by cooperating with the first centering structure on the lower connecting assembly 10 and the second centering structure on the upper connecting assembly 20. Therefore, when replacing the blade coating fixture, only the lower connecting assembly 10 and the upper connecting assembly 20 of the adapter need to be disassembled and installed, reducing wear on the rotary table while ensuring clamping accuracy. Furthermore, because the blade coating fixture and the blade clamped thereto are supported by the support assembly, the adapter's positioning structure / function is separated from its support structure / function, further improving clamping accuracy.

[0039] Figure 3 and Figure 4 Both Figure 1 and Figure 2 The three-dimensional structure diagram of the blade coating fixture adapter during the assembly process is shown, wherein: Figure 3 The support sleeve is omitted. Figure 4 The upper connecting assembly and the base of the blade coating fixture connected thereto are omitted.

[0040] See also Figure 2 and Figure 3In the embodiment of the present disclosure, the lower connecting assembly 10 includes: a lower connecting plate 11 for fixedly connecting to the upper surface of the rotary table 4; a lower connecting sleeve 12 fixedly connected to the lower connecting plate 11; and a connecting shaft 13, the lower end of which is inserted into the lower connecting sleeve 12, and the outer surface of the upper end of the connecting shaft 13 forms the aforementioned first center positioning structure, wherein the lower connecting plate 11, the lower connecting sleeve 12, and the connecting shaft 13 are arranged along the central axis of the lower connecting assembly 10. The upper connecting assembly 20 includes: an upper connecting plate 21 for fixedly connecting to the lower surface of the base 5 of the blade coating fixture; and an upper connecting sleeve 22 fixedly connected to the upper connecting plate 21, and the inner surface of the upper connecting sleeve 22 cooperates with the upper end of the connecting shaft 13 to form the aforementioned second center positioning structure.

[0041] In this embodiment, the lower connecting component 10 and the upper connecting component 20 both include connecting plates and connecting sleeves, which are easy to process. Moreover, since the lower end and the upper end of the connecting shaft 13 are respectively connected to the lower connecting sleeve 12 and the upper connecting sleeve 22, the upper and lower connecting plates and connecting sleeves can be processed into the same structure, and the two ends of the connecting shaft 13 can also be designed into the same structure, thereby providing interchangeability of related components.

[0042] from Figure 2 As can be seen, in this embodiment, the connection plates (lower connection plate 11 and upper connection plate 21) and connection sleeves (lower connection sleeve 12 and upper connection sleeve 22) of the lower connection assembly 10 and the upper connection assembly 20 are separate parts. During assembly, the connection sleeves can be connected to the connection plates using screws. In practice, as an embodiment not shown, for either or both of the lower connection assembly 10 and the upper connection assembly 20, the corresponding connection plates and connection sleeves can be formed as a single integral part, thereby facilitating manufacturing and assembly.

[0043] Continue to see Figure 2 and Figure 3 In the embodiment of the present disclosure, the lower connecting sleeve 12 includes a lower connecting sleeve body 121 and a lower connecting sleeve flange 122 arranged at the lower end of the lower connecting sleeve body 121, and the lower connecting sleeve flange 122 is connected to the lower connecting plate 11; the upper connecting sleeve 22 includes an upper connecting sleeve body 221 and an upper connecting sleeve flange 222 arranged at the upper end of the upper connecting sleeve body 221, and the upper connecting sleeve flange 222 is connected to the upper connecting plate 21.

[0044] In this embodiment, by providing the lower connecting sleeve flange 122 and the upper connecting sleeve flange 222 , it is more convenient to fix the lower connecting sleeve 12 and the upper connecting sleeve 22 together.

[0045] It will be appreciated that in an embodiment not shown in which the corresponding connecting plate and connecting sleeve are formed as an integral part, the lower connecting sleeve flange 122 and the upper connecting sleeve flange 222 may be omitted.

[0046] See also Figure 2 、 Figure 3 and Figure 4 In the embodiment of the present disclosure, the upper and lower ends of the connecting shaft 13 respectively have a shaft drive key 134 extending along the axial direction; the inner surfaces of the upper connecting sleeve 22 and the lower connecting sleeve 12 are respectively provided with a sleeve drive groove 224 extending along the axial direction, and the sleeve drive groove 224 cooperates with the shaft drive key 134, so that the upper connecting sleeve 22 and the lower connecting sleeve 12 are positioned circumferentially relative to the connecting shaft 13.

[0047] In this embodiment, the circumferential positioning and synchronous movement of the upper and lower connecting sleeves are achieved by cooperating with the shaft drive key on the connecting shaft and the sleeve drive grooves on the upper and lower connecting sleeves, so that when the rotary worktable 4 rotates, the adapter can drive the blade coating fixture installed thereon to move synchronously.

[0048] The shaft drive key 134 on the connecting shaft 13 can be a plurality of axially extending teeth arranged along the circumference of the shaft (such as spline teeth in an external spline structure), and accordingly, the sleeve drive groove 224 on the lower connecting sleeve and the upper connecting sleeve can be a plurality of tooth grooves arranged along the circumference of the lower connecting sleeve and the upper connecting sleeve (such as spline grooves in an internal spline structure).

[0049] See also Figure 2 、 Figure 3 and Figure 4 In the embodiment of the present disclosure, shaft connecting holes 135 are respectively provided on the connecting shaft 13 at the positions cooperating with the upper connecting sleeve 22 and the lower connecting sleeve 12; sleeve connecting holes 225 are respectively provided on the upper connecting sleeve 22 and the lower connecting sleeve 12, and the upper connecting sleeve 22 and the lower connecting sleeve 12 are fastened to the connecting shaft 13 by connecting screws cooperating with the sleeve connecting holes 225 and the shaft connecting holes 135.

[0050] In this embodiment, the upper connecting sleeve and the lower connecting sleeve are fastened to the connecting shaft by the fastening action of the connecting screws to avoid relative movement, so the structure of fixing the entire blade coating fixture adapter is more stable, thereby better ensuring the clamping accuracy.

[0051] See also Figure 2 and Figure 4 In an embodiment of the present disclosure, the support assembly 30 includes a support sleeve 32, which is arranged around the lower connecting assembly 10 and the upper connecting assembly 20. A side wall opening 33 is provided on the support sleeve 32, so that the operator can operate the connecting screw through the side wall opening 33.

[0052] In this embodiment, the support sleeve 32 is arranged around the lower connecting assembly 10 and the upper connecting assembly 20, which can provide more stable and reliable support. In addition, by providing the side wall opening 33 on the support sleeve 32, it is convenient to operate the connecting screws.

[0053] from Figure 2 and Figure 4 It can also be seen that the support assembly 30 further includes a support plate 31, which is fixedly connected to the upper surface of the rotary table 4, and a support sleeve 32 is fixedly connected to the support plate 31. The support sleeve 32 has a support sleeve upper end surface 326, which supports the lower surface of the lower connecting plate 11.

[0054] In this embodiment, the support sleeve 32 is arranged around the lower connecting assembly 10 and the upper connecting assembly 20, which can provide more stable and reliable support, and the support plate 31 is provided to facilitate the installation and fixation of the support assembly 30.

[0055] In an embodiment not shown, the upper end surface 326 of the support sleeve can also support the lower surface of the base 5 of the blade coating fixture. It can be known that in this case, the support sleeve 32 also bears the weight of the upper connecting assembly connected to the base 5 of the blade coating fixture.

[0056] See also Figure 3 and Figure 4 In the embodiment of the present disclosure, the connecting shaft 13 and the upper connecting sleeve 22 are respectively provided with reference position marks (for example Figure 2 、 3 and the shaft connecting hole 135 and the sleeve connecting hole 225 shown in 4), by connecting the upper connecting sleeve 22 to the connecting shaft 13 in a state where the reference position marks are aligned, the blade coating fixture connected to the lower connecting assembly 10 is located at a determined reference position in the circumferential direction relative to the rotary worktable 4.

[0057] In this embodiment, by setting a reference position mark, it can be ensured that the blade coating fixture is located at a certain reference position in the circumferential direction relative to the rotating worktable 4, thereby ensuring that the spraying operation on the blade clamped on the blade coating fixture is performed from a predetermined initial position.

[0058] from Figure 3 and Figure 4 It can be seen that the shaft connection hole 135 provided on the connecting shaft 13 and the sleeve connection hole 225 provided on the upper and lower connecting sleeves can serve as reference position marks. That is, the shaft connection hole 135 and the sleeve connection hole 225 simultaneously play the role of fastening and reference position indication. In other embodiments, the reference position mark can be set separately, for example, Figure 2 、 3 The small hole adjacent to the sleeve connecting hole 225 on the upper connecting sleeve 22 shown in FIG4 has a positional alignment with the shaft connecting hole 135 and can be used as a reference position mark.

[0059] See also Figure 4In an embodiment of the present disclosure, a gap may be provided between the upper end surface 136 of the connecting shaft 13 and the lower surface of the upper connecting plate 21 .

[0060] In this embodiment, by forming the gap, the upper end surface 136 of the connecting shaft can be prevented from contacting the lower surface of the upper connecting plate 21, thereby better avoiding the pressure from the blade coating fixture, thereby better ensuring the clamping accuracy.

[0061] from Figure 2 As can also be seen in the figure, in this embodiment, the lower end of the support sleeve and the lower end of the connecting shaft are both supported on the upper surface of the lower connecting plate 11. The axial length of the support sleeve can be set to be greater than the axial length of the connecting shaft 13, so that the upper end surface 326 of the support sleeve is higher than the upper end surface 136 of the connecting shaft. In this way, when the upper end surface 326 of the support sleeve is supported on the lower surface of the upper connecting plate 21, the gap can be provided.

[0062] See also Figure 2 In an embodiment according to the present disclosure, a through central through hole is provided on the lower connecting assembly 10, the upper connecting assembly 20 and the supporting assembly 30, which are coaxially arranged with the central through hole on the rotary worktable 4 and the central through hole on the base 5 of the blade coating fixture, and together constitute a cooling channel P for providing cooling airflow to the blade clamped on the blade coating fixture.

[0063] In this embodiment, the provision of cooling channels P facilitates controlling the blade temperature during the application of thermal barrier coatings. Preferably, sealing rings 137 are provided between the lower end surface of the connecting shaft and the lower connecting plate 11 and between the upper end surface of the connecting shaft and the upper connecting plate 21 to maintain the sealing of the cooling channels.

[0064] The solution disclosed in the present invention is mainly applicable to the design and high-precision clamping of coating fixtures for heavy-load blades exceeding 100 kg. A typical coating spraying system has a rotary worktable. The coating workpiece (the blade to be sprayed) is clamped on the blade coating fixture, and the blade coating fixture is clamped on the table top of the rotary worktable. In the solution disclosed in the present invention, the support assembly 30 serves as a functional block for transferring the load to the rotary worktable, and the upper end face of the support sleeve directly or indirectly (by contacting the upper connecting plate 21) supports the base of the blade coating fixture, playing the role of transferring the gravity load. The upper connecting assembly 20 serves as the basic block of the blade coating fixture, and is used to connect and contact the blade coating fixture. The lower connecting assembly 10 serves as a high-precision positioning and clamping structure for the blade coating fixture, and cooperates with the sleeve drive slot 224 in the upper connecting assembly 20 through the shaft drive key 134 on the connecting shaft 13.

[0065] The assembly sequence of the blade coating fixture adapter 100 disclosed herein is as follows:

[0066] The lower connecting assembly 10 is screwed onto the tabletop of the rotary table (e.g., by screwing it into the T-slot 41 of the rotary table 4) and is not disassembled during the installation of the blade coating fixture. During installation of the lower connecting assembly 10, the orientation of the reference position markings on the lower connecting assembly 10 (e.g., the shaft connection hole 135 on the connecting shaft 13) is simultaneously determined.

[0067] Then, put the entire support assembly 30 on the lower connecting assembly 10 and the rotating worktable 4 and fix them with screws. At the same time, ensure that the opening direction of the support assembly 30 (the direction of the side wall opening 33 on the support sleeve 32) is consistent with the direction of the reference position mark on the lower connecting assembly 10 (the direction of the shaft connecting hole 135 on the connecting shaft 13) (for observation), see Figure 3 and ensure that the support assembly 30 is also assembled and fixed on the rotary table 4 like the lower connecting assembly 10;

[0068] Then, install the upper connecting assembly 20. Specifically, move the upper connecting assembly 20 connected to the base 5 of the blade coating fixture from top to bottom toward the lower connecting assembly 10, observe and align the reference position mark (sleeve connecting hole 225) on the upper connecting sleeve 22 and the shaft connecting hole 135 on the connecting shaft 13, so that the sleeve drive groove 224 on the upper connecting sleeve 22 is aligned with the shaft drive key on the connecting shaft 13 of the lower connecting assembly 10, and assemble them until the lower surface of the upper connecting plate 21 in the upper connecting assembly 20 is in contact with the load contact surface (support sleeve upper end surface 326) in the support assembly 30. See details. Figure 4 , thereby completing the transfer of gravity load to the rotary table 4;

[0069] Finally, screws are used to connect the sleeve connecting hole 225 and the shaft connecting hole 135 through the side wall opening 33 on the supporting sleeve 32, so that the upper connecting sleeve 22 and the connecting shaft 13 are tightened and fixed together.

[0070] If the blade is reshaped or the fixture is changed, it is only necessary to replace the upper connecting assembly 20 and the above position (blade coating fixture). Therefore, it is only necessary to unscrew the screw at the sleeve connecting hole 225 on the upper connecting sleeve 22 and lift the upper connecting assembly 20.

[0071] It can be known that when the blade coating fixture adapter is assembled, the upper connecting component 20 can be installed as a whole with the blade coating fixture as described above to assemble the adapter, or the upper connecting component 20 can be installed on the lower connecting component 10 as a reference block and supported by the support component 30, and then the blade coating fixture is installed on the upper connecting component 20.

[0072] The present disclosure has the following advantages:

[0073] The present invention adds a blade coating fixture transfer mechanism between the blade coating fixture and the rotary worktable for transferring heavy loads to the rotary worktable. The two functions of transferring the heavy load of the coating blade and the fixture to the rotary worktable and high-precision fixture positioning control are respectively realized through the support component and the upper and lower connecting components, so that the fixture load-bearing and positioning are not affected by each other and can be integrated with each other. Therefore, not only can the blade coating fixture and the blade be precisely clamped, but the weight of the heavy-loaded blade coating fixture and the blade can also be transferred to the rotary worktable, thereby reducing damage to the coating fixture and damage to the coating fixture positioning point (the table surface of the rotary worktable) and improving durability.

[0074] In addition, in the solution disclosed herein, since the supporting assembly serving as the load-bearing block and the lower connecting assembly serving as the positioning reference block can be permanently fixed on the working turntable, only a standardized design of the fixture block is required. The design is simple and easy to disassemble during use, which greatly improves the disassembly and assembly efficiency.

[0075] The above is only a preferred embodiment of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present disclosure. These improvements and modifications should also be regarded as within the scope of protection of the present disclosure.
