Description

Technical Field

[0001] This utility model relates to the field of wind turbine component processing technology, and in particular to a clamping and positioning tool for wind turbine component recycling. Background Technology

[0002] The key component used by window cleaning robots to create a vacuum is the fan assembly, which allows the robot to adhere to the glass. The clearance between the fan blades and the fan mount in the fan assembly must meet strict requirements; dimensions that are too high or too low are considered substandard. Furthermore, failure to pass the dynamic balance test also results in a substandard fan assembly. While the fan itself may be intact, fan assemblies that fail the dynamic balance test due to incorrect dimensions or blade deformation are unacceptable. Because the fan blades and motor shaft are interference-fitted, and the clearance between the fan blades and the mount is small, ordinary disassembly tools are difficult to use, making rework very challenging. Therefore, substandard fan assemblies are scrapped entirely, wasting resources and increasing production costs.

[0003] To address the aforementioned problems, this utility model document proposes a clamping and positioning fixture for the recycling of wind turbine components. Utility Model Content

[0004] This utility model provides a clamping and positioning fixture for recycling fan components, which clamps and fixes the fan components, making it easier to separate the fan from the blades and reducing production costs.

[0005] This utility model provides the following technical solution:

[0006] A clamping and positioning fixture for recycling wind turbine components includes a horizontally arranged support platform with a mounting through hole. Parallel limiting blocks are symmetrically arranged on both sides of the mounting through hole on the top surface of the support platform. A support plate is provided on the bottom surface. Pressure plates are provided on the adjacent surfaces of the limiting blocks. A sliding groove is formed between the pressure plates and the support platform. A first limiting plate and a second limiting plate are provided in the sliding groove. Matching clearance grooves for locking the wind turbine motor shaft are provided on the adjacent surfaces of the first limiting plate and the second limiting plate.

[0007] Furthermore, the support platform is provided with slots at the positions corresponding to both ends of the slide groove, and limit plates are provided in the slots.

[0008] Furthermore, there are two support plates. The top surface of the support plate is provided with a threaded hole, the corresponding position of the support platform is provided with a connecting hole, the corresponding position of the limiting block is provided with a countersunk hole, the countersunk hole is provided with a connecting bolt, and the connecting bolt passes through the countersunk hole and the connecting hole and is threadedly connected to the threaded hole.

[0009] Furthermore, a first semi-circular groove is provided on the upper surface of the first limiting plate and at the adjacent position of the second limiting plate, and a second semi-circular groove is provided at the corresponding position of the second limiting plate. The first semi-circular groove and the second semi-circular groove are spliced ​​together to form a circular slot. The bottom thickness of the first semi-circular groove and the second semi-circular groove is less than or equal to the gap between the fan mounting base and the fan blade.

[0010] Furthermore, a handle is provided on the opposite side of the first and second limiting plates.

[0011] In this invention, the fan assembly is placed in the mounting through hole of the support platform, and then the first limiting plate and the second limiting plate are inserted into the gap between the fan positioning seat and the fan blade of the fan assembly, thereby raising and clamping the fan assembly for positioning. This makes it easier to press the motor shaft of the fan out of the fan blade using a riveting machine, saving resources and reducing the production cost of the enterprise.

[0021] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0022] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0023] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0024] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0025] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0026] Example:

[0027] Reference Figures 1-7 As shown, a clamping and positioning fixture for recycling wind turbine components includes a horizontally arranged support platform 1. The support platform 1 has an installation through hole 101. Parallel limiting blocks 2 are symmetrically arranged on both sides of the installation through hole 101 on the top surface of the support platform 1. A support plate 3 is provided on the bottom surface. A pressure plate 4 is provided on the adjacent surface of the limiting block 2. A sliding groove 9 is formed between the pressure plate 4 and the support platform 1. A first limiting plate 5 and a second limiting plate 6 are provided in the sliding groove 9. Matching clearance grooves 10 for locking the wind turbine motor shaft are provided on the adjacent surfaces of the first limiting plate 5 and the second limiting plate 6.

[0028] The horizontal position of the support platform 1 is raised by the support plate 3, and the two limiting plates of the pressure plate 4 slide in the slide groove 9. The first limiting plate 5 and the second limiting plate 6 cooperate to facilitate the clamping and mounting of the fan assembly.

[0029] The first limiting plate 5 and the second limiting plate 6 are moved back to back within the slide groove 9. Then, the fan assembly is placed at the mounting through hole 101 of the support platform 1. Next, the first limiting plate 5 and the second limiting plate 6 are moved towards each other, so that the first limiting plate 5 and the second limiting plate 6 are inserted into the gap between the fan positioning seat and the fan blade, thereby clamping and fixing the fan assembly and placing it in a suspended state. Then, the motor shaft of the fan can be lowered by a riveting machine to separate the motor shaft from the fan blade, thereby separating the fan from the fan blade, completing the recycling of the fan, saving resources and reducing the production cost of the enterprise.

[0030] The motor shaft of the fan is locked in the relief groove 10, so that the first limiting plate 5 and the second limiting plate 6 can abut against each other, ensuring that the contact area between the first limiting plate 5 and the second limiting plate 6 and the lower surface of the fan blade is large. This prevents the fan blade from deforming and breaking when the motor shaft of the fan is pressed out of the fan blade, making it impossible to position the fan assembly and causing the fan assembly to fall off from the mounting through hole 101.

[0031] The support platform 1 has slots 103 at the positions corresponding to both ends of the slide 9, and a limit plate 7 is installed in the slot 103.

[0032] The limiting plate 7 can restrict the sliding of the first limiting plate 5 and the second limiting plate 6 in the slide groove 9. When the fan assembly is clamped between the first limiting plate 5 and the second limiting plate 6, the limiting plate 7 restricts the first limiting plate 5 and the second limiting plate 6, thereby preventing the first limiting plate 5 and the second limiting plate 6 from loosening and changing position when riveting the motor shaft, which would cause the position of the fan assembly to shift and the riveting machine to be unable to accurately rivet the motor shaft, thus making it impossible to separate the fan and the fan blades.

[0033] There are two support plates 3. The top surface of the support plate 3 is provided with a threaded hole 301. The corresponding position of the support platform 1 is provided with a connecting hole 102. The corresponding position of the limit block 2 is provided with a countersunk hole 201. A connecting bolt 11 is provided in the countersunk hole 201. The connecting bolt 11 passes through the countersunk hole 201 and the connecting hole 102 and is threadedly connected to the threaded hole 301.

[0034] The support plate 3 is used to raise the horizontal height of the support platform 1, so that the fan assembly clamped on the first limiting plate 5 and the second limiting plate 6 is in a suspended state. During riveting, there is space below the fan, which can move downwards, thereby separating the fan from the blades.

[0035] The support plate 3, support platform 1 and limit block 2 are fixed together by bolts to ensure the structural stability of the tooling and facilitate the assembly of the clamping and positioning tooling.

[0036] The upper surface of the first limiting plate 5 is provided with a first semi-circular groove 501 adjacent to the second limiting plate 6, and the corresponding position of the second limiting plate 6 is provided with a second semi-circular groove 601. The first semi-circular groove 501 and the second semi-circular groove 601 are spliced ​​together to form a circular slot. The bottom thickness of the first semi-circular groove 501 and the second semi-circular groove 601 is less than or equal to the gap between the fan mounting base and the fan blade.

[0037] The first semi-circular groove 501 and the second semi-circular groove 601 facilitate the positioning of the fan assembly when clamping the fan assembly, and the fan blades are placed in the circular grooves, which further improves the stability of the fan blade clamping structure, thereby ensuring that the riveting machine can accurately act on the motor shaft of the fan.

[0038] A handle bar 8 is provided on the side opposite to the first limiting plate 5 and the second limiting plate 6.

[0039] The handle 8 facilitates the movement of the first limiting plate 5 and the second limiting plate 6 by the worker, improving the ease of operation of clamping and positioning, and thus improving work efficiency.

[0040] In use, the clamping and positioning fixture is installed on the processing platform of the riveting machine. The worker moves the first limiting plate 5 and the second limiting plate 6 backwards using the handle 8. Then, the fan assembly to be recycled is placed at the mounting through hole 101 on the support platform 1. The first limiting plate 5 and the second limiting plate 6 are then moved towards each other, so that the motor shaft is locked in the clearance groove 10 within the gap between the first limiting plate 5 and the second limiting plate 6 and the fan base and fan blades inserted into the fan assembly. Then, the limiting plate 7 is inserted into the slots 103 at both ends of the slide 9 to fix the position of the first limiting plate 5 and the second limiting plate 6, thus completing the clamping and positioning of the fan assembly to be recycled. The riveting machine can then be started to rivet the motor shaft of the fan. By pressing down the motor shaft with the riveting machine, the motor shaft moves downwards, thereby moving the fan downwards and separating it from the fan blades. This completes the separation of the fan from the fan blades, allowing the fan to be recycled. This saves materials and reduces production costs.

[0041] In actual use, the pressure plate 4 and the limiting block 2 are integrally formed, which improves the structural strength and facilitates processing and manufacturing.

[0042] This clamping and positioning fixture can quickly and easily clamp and position wind turbine components, making it convenient to recover and inspect unqualified wind turbine components, and is suitable for widespread application.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
