Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment technology, specifically to an assembly fixture for a wind power slip ring conductive rod. Background Technology

[0002] Wind turbine slip rings are crucial components in wind turbine generators, enabling power and signal transmission between the blade pitch control system and the main control system. Wind turbine generators are typically installed outdoors, facing harsh natural conditions such as wind, rain, and temperature fluctuations. Wind turbine slip rings, made with high-quality materials and featuring a special sealing design, effectively resist these external environmental factors, ensuring stable performance during long-term operation and reducing the probability of failure. A wind turbine slip ring consists of a conductive ring, a slip ring cover, a tail brush, and a conductive rod. The conductive rod connects the conductive ring to the external circuitry, serving to transmit current.

[0003] A search revealed that Chinese Patent Publication No. CN221755181U discloses a tooling fixture for precision machining of wind turbine slip rings, relating to the field of wind turbine slip ring technology. The fixture includes a support plate, a fixing plate fixedly connected to the upper surface of the support plate, a machining plate fixedly connected to the upper surface of the fixing plate, and symmetrical fixing blocks above the machining plate. Multiple equidistant springs are fixedly connected inside each slot, and a clamping block is provided inside each slot. A sliding groove is formed on the upper surface of the machining plate, and symmetrical threaded tubes are fixedly embedded in the inner wall of the sliding groove. Two threaded tubes are connected to a common threaded rod. This utility model has a reasonable design structure. Through the fixed blocks, multiple springs drive the clamping blocks to clamp and fix the components inside the fixing blocks. Furthermore, the elastic force of the springs facilitates the clamping of wind turbine slip rings of different specifications, thereby accelerating the work progress of the operators.

[0004] However, this device also has the following drawbacks: During the assembly of wind turbine slip rings, the conductive rod and the conductive ring need to be press-fitted. The conductive rod is generally a slender rod-shaped body, which is difficult to align with the mounting hole on the conductive ring during press-fitting. It is also difficult to ensure that the conductive rod is perpendicular to the conductive ring during press-fitting, which can easily cause the conductive rod to bend. This device does not solve this problem. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-5 This utility model provides a technical solution: An assembly fixture for a wind turbine slip ring conductive rod includes a pressing assembly. The pressing assembly includes a hydraulic cylinder 1. The telescopic end of the hydraulic cylinder 1 is fixedly connected to the top center of the pressing plate 2. The hydraulic cylinder 1 is fixedly installed in the middle of the top surface of the top plate 15. Two sets of sliding rods 16 are fixedly installed on both sides of the bottom of the top plate 15. The bottom of the sliding rods 16 is fixedly installed on both sides of the top surface of the bottom plate 14. The sliding rods 16 are slidably engaged with sliding seats 17. The sliding seats 17 are fixedly installed on both sides of the pressing plate 2.

[0019] By setting up a hydraulic cylinder 1, the extension end of the hydraulic cylinder 1 can push the pressing plate 2 downward to provide downward pressure to the upper ejector pin 4, thereby pressing the conductive rod body 3 into the mounting hole of the conductive ring body 13. By setting up a slide block 17 to work with the slide rod 16, the stability of the pressing plate 2 when moving up and down can be improved, thereby improving the accuracy of pressing.

[0020] It also includes a positioning component, which includes an upper ejector pin 4 and a lower ejector pin 5. The upper ejector pin 4 and the lower ejector pin 5 are arranged coaxially. The upper ejector pin 4 is installed at the bottom center of the pressure plate 2 by screws and abuts against the top of the conductive rod body 3. The lower ejector pin 5 is installed at the pressure table 11 by screws. The top of the pressure table 11 is a conductive ring body 13, and the bottom of the pressure table 11 is installed at the top center of the base plate 14 by screws.

[0021] By setting the upper ejector pin 4 and the lower ejector pin 5, it is easy to align the mounting holes of the conductive rod body 3 and the conductive ring body 13, and with the help of the pressing assembly, the conductive rod body 3 is precisely pressed into the mounting holes of the conductive ring body 13, achieving a tight fit and improving the accuracy and efficiency of wind power slip ring assembly.

[0022] It also includes a conductive rod body 3, with positioning holes at the top and bottom of the conductive rod body 3. An upper mounting cavity 6 is formed in the center of the upper ejector pin 4, and an upper positioning pin 7 is slidably installed in the upper mounting cavity 6. The upper positioning pin 7 is slidably engaged with the positioning hole at the top of the conductive rod body 3. A first spring 10 is provided in the upper mounting cavity 6, and the bottom of the first spring 10 is fixedly connected to the top of the upper positioning pin 7. The top of the first spring 10 abuts against the top of the upper mounting cavity 6. A lower mounting cavity 8 is formed in the center of the lower ejector pin 5, and a lower positioning pin 9 is slidably installed in the lower mounting cavity 8. A second spring 12 is provided in the lower mounting cavity 8, and the bottom of the second spring 12 abuts against the bottom of the lower mounting cavity 8. The top of the second spring 12 is fixedly connected to the bottom of the lower positioning pin 9. The lower positioning pin 9 is slidably engaged with the positioning hole at the bottom of the conductive rod body 3.

[0023] By using the upper positioning pin 7 and the lower positioning pin 9 in conjunction with the positioning holes on the conductive rod, it is easy for the upper ejector pin 4 and the lower ejector pin 5 to be aligned with the center of the conductive rod, and it can ensure that the conductive rod body 3 is perpendicular to the conductive ring body 13, ensuring smooth pressing and improving the success rate and efficiency of pressing. By using the first spring 10 and the second spring 12 and other structures in conjunction with the upper positioning pin 7 and the lower positioning pin 9, the upper positioning pin 7 and the lower positioning pin 9 can be pushed outward to facilitate alignment and insertion into the positioning hole. Furthermore, during pressing, the upper positioning pin 7 and the lower positioning pin 9 can retract into the upper mounting cavity 6 and the lower mounting cavity 8, thereby preventing damage.

[0024] In practical use, move the device to the designated position, place the conductive ring body 13 on the pressing table 11, align the lower ejector pin 5 with the mounting hole of the conductive ring body 13, then place the corresponding conductive rod body 3 between the upper ejector pin 4 and the lower ejector pin 5, and align the upper positioning pin 7 and the lower positioning pin 9 with the positioning holes at the top and bottom of the conductive rod body 3, respectively. Then start the hydraulic cylinder 1, and the telescopic end of the hydraulic cylinder 1 pushes the pressing plate 2 downward. The upper ejector pin 4 at the bottom of the pressing plate 2 presses the bottom of the conductive rod body 3 into the mounting hole of the conductive ring body 13. As the downward pressure gradually increases, the bottom of the conductive rod body 3 enters the mounting hole of the conductive ring body 13 until there is no visible gap between the insulating layer of the conductive rod body 3 and the surface of the conductive ring body 13.

[0025] 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.
