Description

Technical Field

[0001] This application relates to the field of machining tools for wind turbine diaphragm couplings, and in particular to a tooling fixture for boring diaphragms in wind turbine couplings. Background Technology

[0002] Wind power generation, as an important component of renewable energy, has experienced rapid development globally in recent years. Wind turbine couplings are crucial components connecting wind turbines and generators, primarily transmitting power from the turbine to the generator to produce electricity. Compared to traditional wind turbine couplings, wind turbine diaphragm couplings offer significant advantages such as superior compensation capabilities, high transmission efficiency, strong adaptability, and low maintenance costs.

[0003] The diaphragm assembly is the core component of the wind turbine diaphragm coupling. The diaphragm assembly consists of multiple stacked metal elastic diaphragms, as shown in the attached diagram. Figure 1 The diaphragm 1 is elongated and curved on all four sides, with pin holes 11 at both ends. Pins pass through these holes to secure it to the bushing, transmitting torque and compensating for displacement. The diaphragm is formed and cut from a hot-rolled thin sheet, then heat-treated and precision-machined. Due to significant bending deformation and unevenness, the pin holes need to be machined using methods such as wire cutting. However, the diaphragm is in a free state during machining, and the accuracy of the center distance during machining and subsequent assembly will change due to the bending deformation. Furthermore, significant errors can easily exist between diaphragms. Differences in the center distance and diameter of the pin holes among the diaphragms in the same diaphragm group can lead to additional forces and torques, causing deviations in torque transmission and affecting the overall performance and stability of the coupling. In addition, during operation, inconsistent center distance and diameter of the pin holes among the diaphragms in the same group can result in varying degrees of wear and tear, reducing the service life of the coupling.

[0004] In view of the above-mentioned related technologies, the inventors believe that there is a need to provide a tooling fixture for boring the diaphragm of a wind turbine coupling. Utility Model Content

[0005] In order to improve the accuracy and consistency of the center distance and diameter of the pin holes of each diaphragm in the same diaphragm group of a wind turbine diaphragm coupling, thereby ensuring the stable operation of the coupling and extending its service life, this application provides a tooling fixture for boring the diaphragms of a wind turbine coupling.

[0006] The technical solution provided in this application for a diaphragm boring tooling fixture for wind turbine couplings is as follows:

[0007] A diaphragm boring tooling fixture for wind turbine couplings includes a tooling frame, a pressure plate arranged in the tooling frame for fastening the diaphragm, and fasteners mounted on the top of the tooling frame for abutting the pressure plate; the tooling frame has a first through hole and a second through hole corresponding to two pin holes of the diaphragm, and the pressure plate has a third through hole and a fourth through hole, wherein the third through hole corresponds to the first through hole, and the fourth through hole corresponds to the second through hole.

[0008] By adopting the above technical solution, a pressure plate and fasteners are set in the tooling frame. The pressure plate can press the multi-layer diaphragm flat, and the fasteners are lifted and installed on the top of the tooling frame and abut against the pressure plate. This reduces the probability that the other end of the diaphragm will lift or shift when fastening one end of the diaphragm. The setting of fasteners ensures that the diaphragms are stably arranged, reduces the probability of displacement when the multi-layer diaphragms are processed together, and helps to improve the accuracy and consistency of the pin hole center distance and hole diameter of each diaphragm in the same diaphragm group of the wind turbine diaphragm coupling, thereby ensuring the stable operation of the coupling and extending its service life.

[0009] Optionally, the second through hole includes a first portion and a second portion, and the fourth through hole includes a third portion and a fourth portion, wherein the third portion corresponds to the first portion and the fourth portion corresponds to the second portion.

[0010] By adopting the above technical solution, the second through hole of the tooling fixture includes the first part and the second part, and the third part of the fourth through hole of the pressure plate corresponds to the first part and the fourth part corresponds to the second part, so that the tooling fixture can stably clamp the diaphragm groups of two length specifications, so that the operator does not need to change the fixture when processing the diaphragm groups of these two length specifications, which helps to improve processing efficiency.

[0011] Optionally, the pressure plate has a blind hole on its top surface for the bottom of the fastener to abut against.

[0012] By adopting the above technical solution, a blind hole is set on the top of the pressure plate to match the bottom of the fastener, so that the fastener can stably abut against the pressure plate after it is lowered, reducing the probability of the pressure plate being displaced and helping the tooling fixture to stably clamp the diaphragm.

[0013] Optionally, the fastener is a fully threaded bolt, the fastener has an internal hexagonal groove at the top, and the tooling frame has a threaded through hole at the top for mating with the fastener.

[0014] By adopting the above technical solution, the specific structure of the fastener is disclosed. The fastener is a fully threaded bolt, which is installed on the top of the tooling frame through the thread structure. The connection strength is ideal. The fastener has an internal hexagonal groove on the top, which makes it easy for operators to use tools such as torque wrenches to tighten the fastener, so that the pressure plate and diaphragm are evenly stressed.

[0015] Optionally, the fasteners include a first fastener equidistantly distributed outside the first through hole, a second fastener equidistantly distributed outside the second through hole, and a third fastener disposed between the first fastener and the second fastener.

[0016] By adopting the above technical solution, since the fastener includes a first fastener, a second fastener and a third fastener, the first fastener is arranged outside the first through hole, the second fastener is arranged outside the second through hole, and the third fastener is arranged between the first fastener and the second fastener, which helps to enhance the fastening effect of the fastener on the pressure plate and the diaphragm, thereby reducing the probability of displacement of the diaphragm when boring the pin hole of the diaphragm.

[0017] Optionally, the tooling frame has a positioning groove for placing the film sheet, and the tooling frame has a side plate on one side of the positioning groove for the ends of the film sheet and the pressure plate to abut against each other.

[0018] By adopting the above technical solution, the positioning groove and side plate make it easier for operators to position the diaphragm and pressure plate and arrange them on the tooling frame, and also help to improve the positioning accuracy of the multilayer diaphragm in the length direction.

[0019] Optionally, the tooling frame has two positioning slots, which are located on opposite sides of the tooling frame and share a side plate.

[0020] By adopting the above technical solution, two positioning slots are set on the tooling frame, which allows the operator to place the two sets of membranes in the two positioning slots respectively and then process the two sets of membranes, which helps to simplify the operation process and thus improve processing efficiency.

[0021] Optionally, the tooling frame has two connecting rods on the outside of each of the positioning slots, and the connecting rods are threaded onto the tooling frame.

[0022] By adopting the above technical solution, a connecting rod is provided on the outside of the positioning groove of the tooling frame. The connecting rod is threaded onto the tooling frame, and the connection strength is ideal, which helps to improve the positioning accuracy of the multilayer film in the width direction.

[0023] Optionally, the tooling fixture has a through groove structure located below the first through hole and the second through hole.

[0024] By adopting the above technical solution, the through-slot structure makes it easier for operators to use tools to blow away debris generated during boring of the pin holes of the diaphragm.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A diaphragm boring tooling fixture for wind turbine couplings, comprising a pressure plate and fasteners in the tooling frame. The pressure plate can press the multi-layer diaphragms flat, and the fasteners are lifted and installed on the top of the tooling frame and abut against the pressure plate, reducing the probability of displacement of the multi-layer diaphragms when they are processed together. This helps to improve the accuracy and consistency of the pin hole center distance and hole diameter of each diaphragm in the same diaphragm group of the wind turbine diaphragm coupling, thereby ensuring the stable operation of the coupling and extending its service life.

[0027] 2. By setting blind holes on the top of the pressure plate that mate with the bottom of the fastener, the fastener can stably abut against the pressure plate after it is lowered, reducing the probability of the pressure plate shifting and helping the tooling fixture to stably clamp the diaphragm.

[0028] 3. By setting positioning slots, side plates and connecting rods on the tooling frame, it is easier for operators to position and arrange the diaphragm and pressure plate on the tooling frame, and it also helps to improve the positioning accuracy of the multi-layer diaphragm on the tooling fixture.

[0029] 4. The diaphragm is bored using a tooling fixture. Although the diaphragm will spring back to its pre-processed flexed state after the machining is completed and released, its center distance accuracy returns to the accuracy during machining after stacking and assembly. This eliminates the inefficient and complex labor steps required to eliminate and control the diaphragm's flexural deformation, thus ensuring the reliability, stability, and economy of boring the pin holes of the diaphragm.

[0039] This application discloses a tooling fixture for boring a diaphragm in a wind turbine coupling. The structure of the diaphragm 1 involved in this embodiment can be referenced from [the original document]. Figure 1 This will not be cited separately in the following text.

[0040] Reference Figure 2 and Figure 3The diaphragm boring tooling fixture for wind turbine couplings includes a tooling frame 2, fasteners 3 arranged on top of the tooling frame 2, and a pressure plate 4 for pressing the multi-layer diaphragm 1. The tooling frame 2 includes a mounting base 21, a mounting bottom plate 22 arranged on top of the mounting base 21, a mounting top plate 23, and a mounting post 24 connecting the mounting bottom plate 22 and the mounting top plate 23. In this embodiment, the mounting bottom plate 22, the mounting top plate 23, and the mounting post 24 are integrally connected. The mounting top plate 23 has threaded through holes 231 penetrating its upper and lower surfaces. The fasteners 3 are fully threaded bolts. The fasteners 3 and the threaded through holes 231 can cooperate to allow the fasteners 3 to rise or fall. The top of the fasteners 3 has an internal hexagonal groove 31, which facilitates the operator to use tools such as torque wrenches to tighten the fasteners 3. A specific torque value is applied to each fully threaded bolt in the fasteners 3, so that the pressure plate 4 and the diaphragm 1 are evenly stressed.

[0041] refer to Figure 2 and Figure 3 The fixture 2 is generally rectangular. It has two positioning slots 25 for placing the diaphragm 1 and the pressure plate 4. These slots are located on opposite sides of the fixture 2 along its length. A side plate 26 is located at one end of the fixture 2 along its width, with one end of the diaphragm 1 and the pressure plate 4 abutting against the side plate 26. The two positioning slots 25 share a single side plate 26. Two connecting rods 27 are provided on the outer side of each positioning slot 25. Each connecting rod 27 has a first fixing through hole 271 at its top and bottom, and a first fixing bolt 272 is installed in each of these holes. The mounting top plate 23 and mounting bottom plate 22 have threaded holes that mate with the first fixing bolts 272. The connecting rods 27 are threaded to the front and rear sides of the fixture 2 via the first fixing bolts 272. The positioning slots 25, side plates 26, and connecting rods 27 help improve the positioning accuracy of the multilayer diaphragm 1.

[0042] refer to Figure 2 and Figure 4 The side plate 26 has a second fixing through hole 261 at each of its four corners and a second fixing bolt 262 is installed in the second fixing through hole 261. The mounting top plate 23 and the mounting bottom plate 22 have threaded holes that mate with the second fixing bolt 262. The side plate 26 is threadedly connected to the left side of the tooling frame 2 by the second fixing bolt 262.

[0043] refer to Figure 2 and Figure 5 The tooling frame 2 has a through groove structure, which includes a first through groove 211 located at the top of the mounting base 21 and a second through groove 221 located at the bottom of the mounting base plate 22. The first through groove 211 and the second through groove 221 correspond to each other and form through holes that penetrate the opposite sides of the tooling frame 2, so that the operator can use tools to blow away the debris generated during the processing of the pin holes 11 of the diaphragm 1.

[0044] refer to Figure 5 and Figure 6 The fixture 2 has a first through hole 28 and a second through hole 29 corresponding to the two pin holes 11 of the diaphragm 1. The second through hole 29 includes a first part 291 and a second part 292. The pressure plate 4 has a third through hole 41 and a fourth through hole 42 extending through its upper and lower surfaces. The fourth through hole 42 includes a third part 43 and a fourth part 44, where the third part 43 corresponds to the first part 291 and the fourth part 44 corresponds to the second part 292. The pressure plate 4 has a blind hole 45 on its top surface for the bottom of the fastener 3 to abut against, so that the fastener 3 can stably abut against the pressure plate 4 after descending. The above structure allows the fixture to stably clamp diaphragm sets of two length specifications, so that the operator does not need to change the fixture when processing diaphragm sets of two length specifications, which helps to improve processing efficiency.

[0045] refer to Figure 5 The fastener 3 includes a first fastener 32 equidistantly distributed outside the first through hole 28, a second fastener 33 equidistantly distributed outside the second through hole 29, and a third fastener 34 disposed between the first fastener 32 and the second fastener 33. The arrangement of the first fastener 32 and the second fastener 33 ensures that the tooling fixture has an ideal fastening effect around the pin hole 11 of the diaphragm 1, and the arrangement of the third fastener 34 ensures that the diaphragm 1 is subjected to uniform force.

[0046] The implementation principle of the diaphragm boring tooling fixture for wind turbine couplings in this application embodiment is as follows: The operator first arranges multiple diaphragms 1 of the same diaphragm group in the positioning groove 25 in sequence, so that the diaphragm 1 abuts against the side plate 26. Then, the pressure plate 4 is placed on top of the diaphragm 1 and abuts against the side plate 26. The pressure plate 4 presses the multi-layer diaphragm 1 flat. Then, the operator uses tools such as a torque wrench to make the fastener 3 descend and abut against the blind hole 45 on the top of the pressure plate 4, so that the diaphragm 1 is subjected to uniform force. Finally, the multi-layer diaphragm 1 is processed, which helps to improve the accuracy and consistency of the center distance and hole diameter of the pin holes 11 of each diaphragm 1 in the same diaphragm group of the wind turbine diaphragm coupling, thereby ensuring the stable operation of the coupling and extending its service life.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
