Description

Technical Field

[0001] This utility model relates to the field of stator core technology, specifically to a tooling for stacking and forming stator cores for wind turbine generators. Background Technology

[0002] As is well known, the stator core stacking and forming fixture for wind turbine generators is a type of equipment used to manufacture the stator core of wind turbine generators. Its main function is to accurately stack multiple layers of silicon steel sheets to ensure that the stator core has good magnetic permeability and mechanical strength. In the stator core stacking and forming fixture for wind turbine generators, the positioning device is of great importance, mainly for positioning the multiple layers of silicon steel sheets.

[0003] However, the positioning devices in existing wind turbine stator core stacking and forming fixtures are generally inconvenient to adjust and cannot be easily adapted to various types of silicon steel sheets, which reduces the practicality of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tooling for stacking and forming wind turbine stator cores.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for stacking and forming a stator core of a wind turbine generator, comprising a base plate, a positioning cylinder, a cover plate, a threaded assembly, and an adjustment mechanism. The positioning cylinder is disposed on the top of the base plate, and the cover plate is connected to the bottom of the positioning cylinder via the threaded assembly. The adjustment mechanism comprises a sliding groove, a slider, a frame, a movable block, a motor, and an arc-shaped block. The sliding groove is formed inside the positioning cylinder, one end of the slider is slidably connected to the sliding groove, and the other end of the slider passes through the positioning cylinder and is connected to the arc-shaped block. The inner wall of the arc-shaped block contacts the outer wall of the positioning cylinder. The frame is disposed at the bottom of the cover plate, one end of the movable block is connected to the frame via a bearing, the motor is disposed on the frame, and the other end of the frame is connected to the output end of the motor. Multiple adjustment mechanisms are provided, and a controller is disposed on the top of the cover plate, the controller being electrically connected to the motor.

[0006] To improve the connection effect, the present invention is improved in that the threaded assembly includes a threaded hole, a bolt and a threaded groove, the threaded hole is formed on the cover plate, the threaded groove is formed on the top of the positioning cylinder, and the bolt is threadedly connected to the threaded hole and the threaded groove.

[0007] To improve the connection effect, in this embodiment, the threaded assembly is provided in multiple and symmetrically arranged.

[0008] To improve stability, this utility model is improved by having multiple adjustment mechanisms arranged symmetrically.

[0009] To facilitate pulling the cover plate, the present invention is improved by providing a handle on the top of the cover plate, the handle being fixedly connected to the top of the cover plate, and two handles being provided.

[0010] To improve the strength of the base plate, this utility model has an improvement: the base plate is made of alloy steel.

[0011] Compared with the prior art, this utility model provides a tooling for stacking and forming wind turbine stator cores, which has the following advantages:

[0012] This wind turbine stator core stacking and forming fixture features an adjustment mechanism that facilitates the positioning of silicon steel sheets of different sizes. When positioning silicon steel sheets of different sizes is required, the controller activates the motor in the adjustment mechanism. This mechanism, along with the cooperation of the frame, motor, movable block, slide, slider, and arc block, allows for the positioning of silicon steel sheets of different sizes. This avoids the situation in traditional structures where the inconvenience of positioning silicon steel sheets of different sizes leads to a decrease in equipment practicality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4A tooling for stacking and forming the stator core of a wind turbine generator includes a base plate 1, a positioning cylinder 2, a cover plate 3, a threaded assembly 4, and an adjustment mechanism 6. The positioning cylinder 2 is located on the top of the base plate 1, and the cover plate 3 is connected to the bottom of the positioning cylinder 2 through the threaded assembly 4. The adjustment mechanism 6 includes a sliding groove 7, a slider 8, a frame 9, a movable block 10, a motor 11, and an arc-shaped block 15. The sliding groove 7 is formed inside the positioning cylinder 2. One end of the slider 8 is slidably connected to the sliding groove 7, and the other end of the slider 8 passes through the positioning cylinder 2 and is connected to the arc-shaped block 15. The inner wall of the arc-shaped block 15 contacts the outer wall of the positioning cylinder 2. The frame 9 is located at the bottom of the cover plate 3. One end of the movable block 10 is connected to the frame 9 through a bearing. The motor 11 is located on the frame 9, and the other end of the frame 9 is connected to the output end of the motor 11. Multiple adjustment mechanisms 6 are provided. A controller 12 is located on the top of the cover plate 3, and the controller 12 is electrically connected to the motor 11.

[0020] Working steps: Place the equipment in the designated position and support it with the base plate 1. Connect the cover plate 3 to the positioning cylinder 2 via the threaded assembly 4. Then, place the silicon steel sheet of the specified size on the positioning cylinder 2, so that the inner wall of the circular hole in the center of the silicon steel sheet contacts the arc-shaped block 15 to position the silicon steel sheet. Stack multiple silicon steel sheets together, and then use an external pressing mechanism to apply a certain pressure to press the multiple silicon steel sheets together. The external pressing mechanism is not specifically limited here, such as a hydraulic assembly or other structure. The pressing mechanism only presses the silicon steel sheet and does not contact the positioning cylinder 2. After pressing, wait for a period of time while maintaining a certain pressure. If heating is required, use an external heating device to heat the pressed silicon steel sheet. The external heating device is not specifically limited here. Finally, remove it and send it to an external device for the next step of processing, such as cooling. Those skilled in the art are aware of the subsequent steps, so they will not be described in detail here.

[0021] Adjustment steps: When positioning silicon steel sheets of different sizes is required, place the silicon steel sheet into the positioning cylinder 2, aligning the center of the circular hole of the silicon steel sheet with the center of the positioning cylinder 2. After stacking multiple silicon steel sheets, the cover plate 3 is equipped with a power cord. Connect the power cord to the external mains power to supply power to the motor 11. The power cord will not affect the normal operation of the equipment. Start the motor 11 through the controller 12, causing the motor 11 to drive the movable block 10, which is connected to the frame 9 through the bearing, to rotate. The other end of the movable block 10 contacts the slider 8. When the movable block 10 rotates, it causes the slider 8 to move on the slide groove 7, driving the arc block 15 to move. This causes the arc block 15 to separate from the outer wall of the positioning cylinder 2, so that the outer wall of the arc block 15 contacts the inner wall of the circular hole of the silicon steel sheet to be positioned. The outer wall of the arc block 15 matches the inner wall of the circular hole of the silicon steel sheet. This is not described in detail here. After the movable block 10 rotates to the appropriate angle, the arc block 15 moves to the appropriate position, and then... The silicon steel sheet can be positioned. The controller 12 will simultaneously activate the motors 11 on multiple adjustment mechanisms 6, causing the motors 11 to start synchronously and drive the movable block 10 to rotate synchronously, so that multiple arc blocks 15 move synchronously. After the arc blocks 15 move to the designated position, the controller 12 will turn off the motors 11. The movable block 10 will limit the slider 8 to prevent the arc blocks 15 from moving. Moreover, after the arc blocks 15 come into contact with the inner wall of the circular hole of the silicon steel sheet, they can also limit the arc blocks 15. This will not be described in detail here. When the arc blocks 15 move, the operator needs to manually assist the silicon steel sheet to ensure that the center of the circular hole of the silicon steel sheet matches the center of the positioning cylinder 2. Since the operators of this structure are all personnel in this technical field, they can ensure that the two centers match. This will not be described in detail here. After the silicon steel sheet is positioned by the adjustment mechanism 6, it can be processed. The above steps clearly show how the processing is done. This will not be described in detail here.

[0022] Both slider 8 and groove 7 in the text are T-shaped, and will not be described in detail here.

[0023] During maintenance, when motor 11 malfunctions and needs maintenance, ensure that the equipment is not in operation. By controlling the threaded assembly 4, the cover plate 3 can be separated from the positioning cylinder 2. Then, the cover plate 3 can be separated from the positioning cylinder 2, and the motor 11 can be separated from the positioning cylinder 2, so that the motor 11 can be maintained. This will not be described in detail here.

[0024] In this embodiment, the threaded assembly 4 includes a threaded hole, a bolt 13, and a threaded groove 14. The threaded hole is formed on the cover plate 3, and the threaded groove 14 is formed on the top of the positioning cylinder 2. The bolt 13 is threadedly connected to the threaded hole and the threaded groove 14. Workers can use an external screwdriver to screw the bolt 13 into the threaded hole and the threaded groove 14 to connect the cover plate 3 and the positioning cylinder 2. When disassembly is required, the bolt 13 can be separated from the threaded hole and the threaded groove 14 using an external screwdriver.

[0025] To improve the connection effect, in this embodiment, the threaded assembly 4 is provided in multiple and symmetrically arranged.

[0026] The stability of the aforementioned adjustment mechanism 6 is poor. To solve this problem, in this embodiment, multiple adjustment mechanisms 6 are arranged symmetrically.

[0027] The cover plate 3 is inconvenient to lift. To solve this problem, in this embodiment, the top of the cover plate 3 is provided with a handle 5, which is fixedly connected to the top of the cover plate 3. There are two handles 5.

[0028] The aforementioned base plate 1 has poor strength and is prone to breakage after prolonged use. To address this issue, in this embodiment, the base plate 1 is made of alloy steel.

[0029] The dimensions and structure of all components in this invention are not specifically limited here and need to be produced according to actual conditions. The control method of this invention is to control it by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
