Description

Technical Field

[0001] This invention relates to the technical field of electric motors. More specifically, this invention relates to a direct-drive torque motor. Background Technology

[0002] In existing technologies, to improve the heat dissipation performance of direct-drive torque motors, a spiral channel is usually opened on the motor housing, and an external water pipe is connected to the spiral channel. The external water pipe delivers cooling water into the spiral channel, and the heat generated by the direct-drive torque motor is absorbed by the flowing cooling water, thus achieving a heat dissipation effect. However, scale will be generated during the flow of cooling water in the spiral channel. As scale accumulates on the inner wall of the spiral channel, the heat exchange effect between the cooling water in the spiral channel and the motor housing will gradually decrease, reducing the heat dissipation effect of the motor.

[0023] The cleaning unit also includes cleaning blocks 2023; eight cleaning blocks 2023 are welded to the lower front side of the first connecting plate 201; the eight cleaning blocks 2023 are slidably connected to the adjacent first round rods 2012 respectively.

[0024] The fixed unit located on the right front includes a connecting frame 2016, a torque shaft 2017, a second limiting block 2019, a second elastic telescopic rod 2020, a linkage plate 2021, and a protruding strip 2022; the connecting frame 2016 is bolted to the lower front part of the first scraper 2013 located on the right front; the torque shaft 2017 is installed on the lower side of the connecting frame 2016; the torque shaft 2017 is connected to the adjacent fixed block 2018; a barb is provided on the side of the fixed block 2018 away from the connecting frame 2016; the second limiting block 2019 is bolted to the left side of the connecting frame 2016; the lower side of the first scraper 2013 Two second elastic telescopic rods 2020 are fixedly connected to the front, and both second elastic telescopic rods 2020 are located to the left of the connecting frame 2016; a linkage plate 2021 is fixedly connected between the telescopic ends of the two second elastic telescopic rods 2020; the linkage plate 2021 is slidably connected to the adjacent first scraper 2013; the lower side of the linkage plate 2021 is in contact with the adjacent fixed block 2018; the upper side of the linkage plate 2021 is in contact with the adjacent second connecting block 208; a protruding strip 2022 is welded to the front part of the lower side of the second scraper 2015 located on the right side of the front, and the protruding strip 2022 cooperates with the adjacent fixed block 2018.

[0025] The front-mounted mixing unit includes a fourth connecting block 2024 and a spiral block 2025; three fourth connecting blocks 2024 are fixedly connected to the front side of the first connecting plate 201; all three fourth connecting blocks 2024 are in close contact with the base plate 202; a spiral block 2025 is welded to the inner side of each of the three fourth connecting blocks 2024.

[0026] During preparation, connect the external water inlet pipe to the first pipe 204 and the external water outlet pipe to the second pipe 205. The external water inlet pipe supplies cooling water to the first pipe 204. The cooling water flows upward into the first channel 206, then from the first channel 206 into the second channel 207, then from the second channel 207 into the third channel 209, then from the third channel 209 into the groove 91 of the first connecting plate 201, then from the groove 91 into the second first channel 206 from right to left, and so on, finally flowing into the second pipe 205. During the process of the water flowing into the external outlet pipe, the heat generated by the operation of the motor body 2 is conducted to the outer casing 1, and then the heat is absorbed by the flowing cooling water, achieving the heat dissipation effect of the motor body 2. At the same time, after the water flows into the groove 91, it passes through the middle of the fourth connecting block 2024. At this time, the spiral block 2025 guides the flowing water, so that it spirals through the fourth connecting block 2024, thereby achieving a stirring effect on the cooling water, so that the cooling water with a higher outer temperature and the cooling water with a lower middle temperature are evenly mixed, so that the heat in the cooling water is more uniform and the heat exchange effect is improved. As usage time increases, scale will accumulate on the inner walls of the first channel 206, the second channel 207, and the third channel 209, thereby reducing the heat exchange effect. During regular maintenance, the base plate 202 is manually disassembled and then pulled downwards. The base plate 202 drives the first round rod 2012 downwards, which in turn drives the first scraper 2013 downwards. The first scraper 2013 then moves downwards to fit against the inner walls of the second channel 207 and the first channel 206, scraping off the scale. During use, the scale on the inner walls of the first channel 206 and the second channel 207 is scraped off by the first scraper 2013, avoiding the problem of reduced heat dissipation due to scale accumulation on the inner walls of the spiral channels in existing technologies. During the scale removal process, due to the gap between the first channel 206 and the third channel 209, the sum of the widths of the first channel 206 and the third channel 209 is less than the width of the second channel 207. As a result, the first scraper 2013 cannot scrape off the scale in the middle of the inner wall of the second channel 207. At this time, the first scraper 2013 drives the first elastic telescopic rod 2014 to move downward, and the first elastic telescopic rod 2014 drives the second scraper 2015 to move downward. The side of the second scraper 2015 away from the first elastic telescopic rod 2014 contacts the inclined surface of the first limiting block 2010. As a result, the second scraper 2015 continues to move downward while moving towards the first elastic telescopic rod 2014 and compressing the first elastic telescopic rod 2014. During this process, the scale in the middle of the inner wall of the second channel 207 is scraped off by the second scraper 2015, avoiding the occurrence of scale residue. During the scale removal process, the base plate 202 drives the first round rod 2012 to move downward, causing the first round rod 2012 to move downward in the cleaning block 2023, thereby causing the cleaning block 2023 to scrape off the scale attached to the first round rod 2012. That is, while cleaning the first channel 206, the first round rod 2012 is automatically cleaned, saving cleaning steps and improving convenience. During the cleaning process, the first scraper 2013 causes the parts on it to move downwards, causing the linkage plate 2021 to stop contacting the second connecting block 208. The second elastic telescopic rod 2020 rebounds, causing the linkage plate 2021 to move upwards, thereby causing the torque shaft 2017 to drive the fixing block 2018 to flip upwards and contact the second limiting block 2019 through torque. After the cleaning block 2023 has cleaned the first round rod 2012, the first connecting plate 201 is manually disassembled, thereby removing the first scraper 2013 and the second scraper 2015. After being removed, the first elastic telescopic rod 2014 rebounds, causing the second scraper 2015 to unfold. Then, the first scraper 2013 and the second scraper 2015 are manually scrubbed to remove any noticeable scale. Next, the second scraper 2015 is manually pushed towards the first elastic telescopic rod 2014, causing the protrusion 2022 to engage with the fixing block 2018. The fixing block 2018 then secures the protrusion 2022, thus fixing the second scraper 2015 in place. At this point, the first... The second scraper 2015 is located inside the lower side of the first scraper 2013. Then, the first connecting plate 201 and the base plate 202 are manually reinstalled back in their original positions, causing the first round rod 2012 to drive the first scraper 2013 back to its original position. The first scraper 2013 drives the parts on it to move, causing the linkage plate 2021 to contact the second connecting block 208. The second connecting block 208 blocks the upward-moving linkage plate 2021, thereby causing the linkage plate 2021 to push the fixing block 2018 downward and flip it, stopping the fixing block 2018 from being fixed. The protruding strip 2022, and then the first elastic telescopic rod 2014 rebounds and drives the second scraper 2015 to move back to its original position. In use, the first scraper 2013 is temporarily retracted by the fixing block 2018, which solves the problem that it is difficult to manually put the first scraper 2013 in the first channel 206. After the first scraper 2013 moves to the second channel 207, it is automatically re-expanded by the linkage plate 2021 for the next cleaning of the inner wall of the second channel 207.

[0027] Implementation Plan 2 Based on implementation plan 1, such as Figure 1-3 and Figure 12-13As shown, the shock absorption assembly includes a second connecting plate 301, an L-shaped plate 302, a second round rod 303, a cover plate 304, and elastic units; two second connecting plates 301 are welded to the rear side of the outer casing 1; an L-shaped plate 302 is slidably connected to each of the two second connecting plates 301; two second round rods 303 are welded to the rear side of each of the two L-shaped plates 302, and the second round rods 303 are slidably connected to the adjacent second connecting plates 301; a cover plate 304 is bolted to the opposite side of each of the two L-shaped plates 302, and the cover plate 304 is slidably connected to the adjacent second connecting plate 301; three elastic units are connected between each adjacent second connecting plate 301 and L-shaped plate 302.

[0028] The elastic unit located on the upper left includes a cylinder 305, a spring 306, a locking block 307, and a retaining ring 308; a cylinder 305 is welded to the upper rear part of the second connecting plate 301 on the left; a spring 306 is sleeved inside the cylinder 305; a locking block 307 is welded to the rear end of the spring 306; a retaining ring 308 is welded to the upper side of the L-shaped plate 302 on the left, and the retaining ring 308 is located behind the cylinder 305; the locking block 307 and the retaining ring 308 are engaged.

[0029] During preparation, the L-shaped plate 302 is fixed to the workbench with bolts to complete the fixing operation of the motor body 2. The motor body 2 will generate vibration during operation. The vibration is transmitted to the second connecting plate 301 through the outer shell 1. The second connecting plate 301 is damped by the spring 306, thereby damping the motor body 2 and helping to extend the service life of the motor body 2. When the spring 306 needs to be replaced, the cover plate 304 is removed manually, and then the spring 306 is pulled upward. The spring 306 drives the locking block 307 to move upward, so that the locking block 307 moves away from the locking ring 308. Then the spring 306 is pulled out from the cylinder 305 to achieve quick replacement and make the replacement process more convenient.
