Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a polishing equipment for enameled wire. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer demands is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal properties.

[0003] Enamelled wire, as a key material for generator windings, directly affects insulation performance and electric field distribution due to its surface finish. In existing technologies, microburrs are easily generated during the drawing or coating process of enamelled wire, leading to concentrated electric fields during operation, potentially causing partial discharge or even insulation breakdown. Traditional polishing equipment often uses single-sided grinding or fixed sandpaper friction, resulting in uneven polishing, low efficiency, and difficulty in adapting to different types of enamelled wire. Therefore, improving existing enamelled wire polishing equipment and designing a new type to address these technical shortcomings and enhance the overall practicality of enamelled wire polishing equipment is particularly important. Utility Model Content

[0004] The purpose of this invention is to provide an enameled wire polishing device. This device can adjust the distance between the first and second abrasive wheels according to actual conditions, thereby adapting to polishing enameled wires of different specifications, improving its versatility. Furthermore, multi-layer polishing ensures more uniform polishing, preventing electric field concentration caused by burrs later on, thus improving polishing quality and efficiency. Simultaneously, water spraying to the abrasive area cools the area and wets the polishing debris, allowing it to enter a collection box to prevent splashing and injury. A waterproof membrane prevents water and debris from entering the main body, extending its service life. A filter screen collects the debris for easy recycling, improving the overall practicality of the enameled wire polishing device and solving the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A wire polishing device includes a main body 1. Two sets of upper sliding grooves 101 and multiple sets of lower sliding grooves 102 are formed on one side of the main body 1. A waterproof membrane 801 is fixedly connected inside both the upper and lower sliding grooves 101 and 102. A first lifting block 5 is slidably connected to the outside of the waterproof membrane 801 and inside the upper sliding groove 101. A second lifting block 6 is slidably connected to the outside of the waterproof membrane 801 and inside the lower sliding groove 102. A first abrasive wheel 502 is rotatably connected to one end of the first lifting block 5 extending to the outside of the main body 1. A second abrasive wheel 602 is rotatably connected to one end of the second lifting block 6 extending to the outside of the main body 1. A second motor 3 and two sets of fixing blocks 3 are fixedly connected inside the main body 1 and at the bottom of the lower sliding groove 102. 1. The top of the second motor 3 is the drive end and is fixedly connected to a second rotating wheel 301. The top of the fixing block 31, located inside the main body 1, is rotatably connected to a third rotating wheel 302. The second rotating wheel 301 and the two sets of third rotating wheels 302 are respectively meshed and connected by two sets of second synchronous belts 303. The upper sliding groove 101 and the lower sliding groove 102 are distributed alternately. The two sets of fixing blocks 31 are respectively located on both sides of the second motor 3. Inside the main body 1, at the top of the two sets of upper sliding grooves 101, the first motor 2 and the fixing column 21 are respectively fixedly connected. The bottom of the first motor 2 is the drive end and is fixedly connected to a first rotating wheel 201. The bottom of the fixing column 21, located inside the main body 1, is rotatably connected to a first rotating wheel 201. Two sets of first rotating wheels 201 are connected by a first synchronous belt 202. The first lifting block 5 has a first threaded rod 501 inside, and the second lifting block 6 has a second threaded rod 601 inside. The first threaded rod 501 is fixedly connected to the adjacent first rotating wheel 201. The second rotating wheel 301 and the third rotating wheel 302 are respectively fixedly connected to their respective adjacent second threaded rods 601. When the enameled wire polishing equipment is put into use, the power is turned on, and the drive end of the first motor 2 rotates, thereby driving one set of first rotating wheels 201 to rotate, which in turn drives the first synchronous belt 202 and the other set of first rotating wheels 201 to rotate synchronously, thereby driving the two sets of first threaded rods 501 to rotate synchronously, thus driving the two sets of... The first lifting block 5 rises and falls synchronously, thereby driving the two sets of first grinding wheels 502 to rise and fall synchronously. The drive end of the second motor 3 rotates, thereby driving the second rotating wheel 301 to rotate, which in turn drives the two sets of second synchronous belts 303 and the third rotating wheel 302 to rotate synchronously, thereby driving multiple sets of second threaded rods 601 to rotate synchronously, which in turn drives multiple sets of second lifting blocks 6 to rise and fall synchronously, which in turn drives multiple sets of second grinding wheels 602 to rise and fall synchronously. This allows the spacing between the first grinding wheel 502 and the second grinding wheel 602 to be adjusted according to actual conditions, thus adapting to polishing different specifications of enameled wire, improving versatility. Furthermore, the multi-layer polishing makes the polishing more uniform, avoiding electric field concentration caused by burrs in the later stage, and improving polishing quality and efficiency.

[0024] Furthermore, a third motor 4 is fixedly connected to one end of the main body 1, and a collecting roller 401 is fixedly connected to the drive end of the third motor 4. When the enameled wire polishing equipment is put into use, the power is turned on, the drive end of the third motor 4 rotates, thereby driving the collecting roller 401 to rotate, thereby winding up the polished enameled wire.

[0025] The main body 1 has multiple sets of equally spaced first heat-conducting strips 701 fixedly connected inside the main body 1 on the side of the first motor 2 away from the first grinding wheel 502. A first fan 7 is provided inside the main body 1 on the top of the first heat-conducting strips 701. The main body 1 has multiple sets of equally spaced second heat-conducting strips 703 fixedly connected inside the main body 1 on the side of the second motor 3 away from the second grinding wheel 602. A second fan 702 is provided inside the main body 1 on the side of the second heat-conducting strips 703 away from the second motor 3. When the enameled wire polishing equipment is put into use and the power is turned on, the multiple sets of first heat-conducting strips 701 conduct the heat emitted by the first motor 2 during operation to the bottom of the first fan 7, which then blows the heat out of the main body 1 for heat dissipation. The multiple sets of second heat-conducting strips 703 conduct the heat emitted by the second motor 3 during operation to the bottom of the second fan 702, which then blows the heat out of the main body 1 for heat dissipation.

[0026] Secondly, a nozzle 8 is fixedly connected to one side of the main body 1 and at the top of the first grinding wheel 502, and a collection box 802 is provided on one side of the main body 1 and at the bottom of the second grinding wheel 602. The collection box 802 is equipped with a filter screen 803. When the enameled wire polishing equipment is put into use, the power is turned on, and the nozzle 8 sprays water onto the first grinding wheel 502 and the second grinding wheel 602 to cool down the grinding areas of the first grinding wheel 502 and the second grinding wheel 602. It can also wet the debris generated during the polishing process and put it into the collection box 802 to prevent it from splashing and injuring people. The waterproof membrane 801 prevents water and debris from entering the interior of the main body 1 and extends its service life. The filter screen collects the debris for easy recycling, and the water flows away from the bottom.

[0027] In this embodiment, the specific implementation scenario is as follows: In actual use, when the enameled wire polishing equipment is put into use, one end of the enameled wire is passed through the top of multiple sets of second grinding wheels 602 and the bottom of the first grinding wheel 502, and then fixed around the collecting roller 401. According to the specifications of the enameled wire, the power is turned on, and the drive end of the first motor 2 rotates, thereby driving a set of first rotating wheels 201 to rotate, thereby driving the first synchronous belt 202 and another set of first rotating wheels 201 to rotate synchronously, thereby driving the two sets of first threaded rods 501 to rotate synchronously, thereby driving the two sets of first lifting blocks 5 to descend synchronously, thereby driving the two... The first grinding wheel 502 descends synchronously, and the drive end of the second motor 3 rotates, thereby driving the second rotating wheel 301 to rotate. This, in turn, drives the two sets of second synchronous belts 303 and the third rotating wheel 302 to rotate synchronously, which in turn drives multiple sets of second threaded rods 601 to rotate synchronously, which in turn drives multiple sets of second lifting blocks 6 to rise synchronously, which in turn drives multiple sets of second grinding wheels 602 to rise synchronously. This ensures that the distance between the first grinding wheel 502 and the second grinding wheel 602 is suitable for polishing the enameled wire, improving its versatility. Multiple sets of first heat-conducting strips 701 conduct the heat dissipated by the first motor 2 during operation to the bottom of the first fan 7. The heat generated by the second motor 3 during operation is dissipated by the first fan 7 blowing heat out of the interior of the main body 1. Multiple sets of second heat-conducting strips 703 conduct the heat generated by the second motor 3 to the bottom of the second fan 702, from which it is blown out of the interior of the main body 1 for heat dissipation. The drive end of the third motor 4 rotates, thereby driving the collecting roller 401 to rotate, thus drawing and winding the enameled wire between the first grinding wheel 502 and the second grinding wheel 602. The enameled wire undergoes multi-layer polishing between the first grinding wheel 502 and the second grinding wheel 602, making the polishing more uniform, avoiding electric field concentration caused by burrs in the later stage, and improving the polishing quality. This invention improves the efficiency of polishing and winding enameled wire. During the polishing process, the nozzle 8 sprays water onto the first abrasive wheel 502 and the second abrasive wheel 602, cooling the abrasive surfaces of the two wheels and also wetting the polishing debris before it enters the collection box 802 to prevent it from splashing and injuring people. The waterproof membrane 801 prevents water and debris from entering the interior of the main body 1, extending its service life. The filter screen collects the debris for easy recycling, and the water flows away from the bottom. Compared with existing enameled wire polishing equipment, this invention improves the overall practicality of enameled wire polishing equipment through its design.

[0028] 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.
