Description

Technical Field

[0001] The invention relates to the technical field of motor stator processing, in particular to a motor stator dust removal tool provided with auxiliary components. Background Art

[0002] The motor stator is a crucial component of an electric motor or generator. It is a stationary component that houses the electromagnetic poles and coils that generate a magnetic field. The stator typically consists of an iron core with coils wound around it. When current passes through the coils, a magnetic field is generated on the core. During the stator assembly process, the stator, exposed to the environment, can carry dust and generate static electricity. This static electricity can cause dust to adhere to the stator. If not removed, the dust accumulates, adversely affecting stator assembly and, in severe cases, even causing the motor to fail and resulting in unnecessary losses.

[0003] When removing dust from the motor stator, it is mostly done manually, which is inefficient. After dust removal, a lot of dust and debris remain on the inner wall of the stator, resulting in unsatisfactory dust removal effects. In addition, dust and dirt will spread into the air, affecting the air quality in the workshop.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a motor stator dust removal tool with auxiliary components is proposed. Summary of the Invention

A connecting pipe is sleeved on the upper end of the liquid outlet pipe, and a purifier is provided in the middle of the connecting pipe. The upper end of the connecting pipe is connected to a liquid storage tank, and the liquid storage tank is located above the liquid inlet. The liquid storage tank and the purifier are both fixedly connected to the upper shell.

[0011] Furthermore, a clamping assembly is provided in the middle of the placement cavity, and the clamping assembly includes a rotating groove, an annular groove and ball bearings. A rotating groove is provided in the middle of the placement cavity, and an annular groove is provided below the rotating groove. Ball bearings are circumferentially distributed on the upper wall of the rotating groove and the lower wall of the annular groove.

[0012] Furthermore, the clamping assembly also includes a ring plate, a telescopic rod, a swivel and a gear ring. A ring plate is arranged in the ring groove, and a telescopic rod is fixedly connected above the ring plate. A swivel is fixedly connected above the telescopic rod, and a gear ring is fixedly connected to the outside of the swivel.

[0013] Furthermore, the telescopic rods are equidistantly distributed around the ring plate, and the ring plate is rotatably connected to the lower shell through a ring groove. The swivel and gear ring rotate in the swivel groove, and the swivel and gear ring are slidably connected to the lower shell through the swivel groove.

[0014] Furthermore, the clamping assembly also includes a clamping groove, a pushing rod and a clamping plate. The inner wall of the rotating ring is symmetrically provided with a clamping groove, and a pushing rod is fixedly connected in the clamping groove. The other end of the pushing rod is fixedly connected to a clamping plate, and the clamping plate is arc-shaped.

[0015] Furthermore, the clamping assembly also includes a drive cavity, a motor and a drive wheel. A drive cavity is opened on one side of the rotating groove, and a motor is fixedly connected to the drive cavity. The upper end of the motor is fixedly connected to the drive wheel, and the drive wheel is engaged with the gear ring.

[0016] The present invention provides a motor stator dust removal tool provided with an auxiliary component, which has the following beneficial effects: when in use, the stator can be dusted in a confined space to prevent dust from diffusing in the air, and during the dust removal process, multiple dust removal operations can be performed to improve the dust removal effect, and the stator can be tested to ensure that glycerin does not remain on the stator.

[0017] 1. When the present invention is in use, after the stator is placed in the placement cavity and clamped firmly, the lifting rod lowers the upper shell to fit tightly between the lower shell and the upper shell, completely covering the stator. During the lowering process of the upper shell, the sealing ring is clamped into the sealing groove and the sealing ring is pressed into the sealing groove, thereby sealing the upper shell and the lower shell, so that the stator is in a closed environment, avoiding dust and dirt from spreading into the air when the stator is dusted, affecting the air quality of the workshop, and avoiding collision with the stator during the cleaning process to cause damage to the stator. In summary, when in use, the stator can be placed in a closed space to avoid dust from diffusing in the air, and at the same time, the stator can be avoided from being damaged by collision.

[0018] 2. When the stator is cleaned, the present invention starts the vacuum pump, the solenoid valve in the air inlet is opened, and the solenoid valve in the liquid inlet is closed, and the outside air can enter the uniform distribution chamber from the air inlet and be sprayed to the stator through the nozzle to perform the initial cleaning of the stator, blowing off the dust adhering to the stator. The air flow carries the dust from the placement chamber into the storage chamber. After the dust is trapped in the dust box by the filter, the air enters the outlet pipe from the storage chamber through the diverter pipe and is then extracted by the vacuum pump. After the initial cleaning is completed, the solenoid valves in the air inlet and the liquid inlet are switched. In the open and closed state, the vacuum pump keeps running, and the glycerin in the liquid storage tank can be drawn into the uniform distribution chamber from the liquid inlet, and sprayed onto the stator through the nozzle for secondary cleaning, so as to dissolve and wash off the dust and stains that are firmly attached to the stator. The glycerin carrying the stains enters the storage chamber from the placement chamber. After the stains are trapped in the dust box by the filter, the glycerin enters the diversion pipe from the storage chamber. The diaphragm can block the glycerin, preventing it from entering the outlet pipe while only allowing air to enter the outlet pipe. After the glycerin in the liquid storage tank is drawn out, a negative pressure is formed inside, which can be Under the action of negative pressure, the glycerin in the shunt pipe is recovered into the liquid storage tank through the liquid outlet pipe. Before the glycerin flows back to the liquid storage tank, the purifier can purify the glycerin to keep it clean and prevent dust from adhering to the stator after cleaning. When the upper shell is raised and lowered, the liquid outlet pipe can slide in the connecting pipe to maintain the connection between the liquid outlet pipe and the connecting pipe to avoid glycerin leakage. The one-way valve can control the flow direction of glycerin to prevent glycerin from flowing back from the liquid outlet pipe to the shunt pipe. After the secondary cleaning is completed, the solenoid valve in the liquid inlet is closed. Close, the vacuum pump continues to run, and the placement chamber is pumped into negative pressure to accelerate the volatilization of glycerin. At the same time, the solenoid valve in the air inlet is opened intermittently, so that air can be sprayed intermittently from the nozzle to the stator, and the volatilized glycerin is sent out of the placement chamber while maintaining the negative pressure, thereby removing the glycerin on the surface of the stator and avoiding glycerin residue on the stator. After cleaning, the dust box can be pulled out of the storage chamber for cleaning. In summary, during use, the stator can be cleaned multiple times to ensure the cleaning effect while avoiding glycerin residue on the stator.

[0019] 3. In the present invention, after the stator is placed in the placement cavity, the push rod pushes the clamping plate out of the clamping groove so that the clamping plate clamps the stator. After the clamping is firm, the telescopic rod drives the swivel to rise in the rotating groove so that the bottom end of the stator is separated from the contact with the placement cavity, thereby avoiding damage caused by friction between the stator and the inner wall of the placement cavity during cleaning. During cleaning, the motor starts and drives the driving wheel to rotate, which can drive the swivel to rotate in the rotating groove through the gear ring, so that the stator rotates in the placement cavity and the stator is fully cleaned. At the same time, the swivel drives the ring plate to rotate in the ring groove through the telescopic rod, and the ball can assist the swivel and the ring plate to rotate in the rotating groove and the ring groove to ensure smooth rotation. In the cleaning process, the telescopic rod can first lower the swivel to release the contact. The stator is clamped, and the stator is clamped again after the rotating ring rotates 90°, and the clamping point is switched to clean the clamping point to ensure the cleaning effect. When removing glycerin, the stator surface can be energized through the clamping plate, and the winding on the stator can be energized for detection. If glycerin remains on the stator, there will be current on the winding. If the winding is not energized, it means that the glycerin has been removed. When lowering and clamping the stator, the motor stops running to avoid damage caused by friction between the stator and the inner wall of the placement cavity. In summary, the stator can be clamped and adjusted during cleaning to ensure the cleaning effect, and it can be detected after cleaning to avoid glycerin remaining on the stator.

[0023] See also Figures 1 to 5The sealing ring 302 is connected to the lower shell 1 by a sealing groove 4, and the contact surfaces of the upper shell 301 and the lower shell 1 are in contact with each other. The lower wall of the uniformly distributed chamber 303 is a truncated cone, and the lower part of the nozzle 304 is an inclined trumpet shape, and the nozzles 304 are equidistantly distributed around the uniformly distributed chamber 303. A placement cavity 6 is provided in the middle of the lower shell 1, and a storage cavity 7 is provided below the placement cavity 6. A dust box 8 is slidably connected in the storage cavity 7, and a filter screen 9 is provided on the lower wall of the dust box 8. A diverter pipe 10 is provided below the storage cavity 7, and an outlet is connected above the diverter pipe 10. The air pipe 11 has a diaphragm 12 fixedly connected to one end of the air outlet pipe 11, and the other end of the air outlet pipe 11 is connected to an air pump 13, which is fixedly connected to the lower shell 1. A liquid outlet pipe 14 is provided below the shunt pipe 10, and a one-way valve 15 is provided in the liquid outlet pipe 14. A connecting pipe 16 is sleeved on the upper end of the liquid outlet pipe 14, and a purifier 17 is provided in the middle of the connecting pipe 16. The upper end of the connecting pipe 16 is connected to a liquid storage tank 18, and the liquid storage tank 18 is located above the liquid inlet 306. The liquid storage tank 18 and the purifier 17 are both fixedly connected to the upper shell 301. The specific operation is as follows. When in use, after the stator is placed in the placement cavity 6 and clamped firmly, the lifting rod 2 lowers the upper shell 301 to the lower shell 1 and the upper shell 301 to fit tightly, completely covering the stator. During the lowering process of the upper shell 301, the sealing ring 302 is stuck in the sealing groove 4 and the sealing ring 5 is pressed into the sealing groove 4, thereby sealing the upper shell 301 and the lower shell 1, so that the stator is in a closed environment, avoiding dust and dirt from spreading into the air when the stator is dusted, affecting the air quality of the workshop, and avoiding collision with the stator during the cleaning process to cause damage to the stator. In summary, when in use, the stator can be placed in a closed space to avoid dust from diffusing in the air and also avoid damage to the stator due to collision. When the stator is to be cleaned, the vacuum machine 13 is started, the solenoid valve 307 in the air inlet 305 is opened, and the solenoid valve 307 in the liquid inlet 306 is closed, and the outside air can enter the uniform distribution chamber 303 from the air inlet 305 and be sprayed to the stator through the nozzle 304, thereby performing the initial cleaning of the stator and blowing off the dust adhering to the stator. The air flow carries the dust from the placement chamber 6 into the storage chamber 7. After the dust is trapped in the dust collecting box 8 by the filter 9, the air enters the outlet pipe 11 from the storage chamber 7 through the shunt pipe 10 and is then extracted by the vacuum machine 13. After the initial cleaning is completed, the solenoid valve 307 in the air inlet 305 and the liquid inlet 306 are switched to the open and closed states, and the vacuum machine 13 continues to run, so that the glycerin in the liquid storage tank 18 can be drawn into the uniform distribution chamber from the liquid inlet 306. The cloth chamber 303 is sprayed onto the stator through the nozzle 304 for secondary cleaning, dissolving and washing away the dust and stains that are firmly adhered to the stator. The glycerin carrying the stains enters the storage chamber 7 from the placement chamber 6. After the stains are trapped in the dust box 8 by the filter 9, the glycerin enters the shunt pipe 10 from the storage chamber 7. The diaphragm 12 can block the glycerin and prevent it from entering the outlet pipe 11 while only allowing air to enter the outlet pipe 11. After the glycerin in the liquid storage tank 18 is drawn out, a negative pressure is formed inside. Under the action of the negative pressure, the glycerin in the shunt pipe 10 can be recovered into the liquid storage tank 18 through the liquid outlet pipe 14. Before the glycerin flows back to the liquid storage tank 18, the purifier 17 can purify the glycerin. The purifier 17 uses an ion exchange method to purify the glycerin. The ion exchange method is a method of exchanging ions of impurities in glycerin through ion exchange resin to keep the glycerin clean and prevent dust from adhering to the stator after cleaning. When the upper shell 301 is raised or lowered, the liquid outlet pipe 14 can slide in the connecting pipe 16 to maintain the connection between the liquid outlet pipe 14 and the connecting pipe 16 to prevent glycerin leakage. The one-way valve 15 can control the flow direction of glycerin to prevent glycerin from flowing back from the liquid outlet pipe 14 to the diversion pipe 10. After the secondary cleaning is completed, the solenoid valve 307 in the liquid inlet 306 is closed, and the vacuum pump 13 continues to run, pumping the placement chamber 6 into a negative pressure to accelerate the volatilization of glycerin. At the same time, the solenoid valve 307 in the air inlet 305 is intermittently opened, so that air can be intermittently sprayed from the nozzle 304 to the stator.While maintaining negative pressure, the volatilized glycerin is sent out of the placement chamber 6, thereby removing the glycerin on the stator surface and preventing glycerin from remaining on the stator. After cleaning is completed, the dust collection box 8 can be pulled out of the storage chamber 7 for cleaning. In summary, during use, the stator can be cleaned multiple times, ensuring the cleaning effect while preventing glycerin from remaining on the stator.

[0024] See also Figures 4 to 7 , a clamping assembly 19 is provided in the middle of the placement cavity 6, the clamping assembly 19 includes a rotating groove 1901, an annular groove 1902 and a ball 1903, a rotating groove 1901 is provided in the middle of the placement cavity 6, and an annular groove 1902 is provided below the rotating groove 1901, and the upper wall of the rotating groove 1901 and the lower wall of the annular groove 1902 are circumferentially distributed with balls 1903, the clamping assembly 19 also includes a ring plate 1904, a telescopic rod 1905, a rotating ring 1906 and a gear ring 1907, a ring plate 1904 is provided in the annular groove 1902, and the telescopic rod 1905 is fixedly connected above the ring plate 1904, the telescopic rod 1905 is fixedly connected to the rotating ring 1906, and the outer side of the rotating ring 1906 is fixedly connected to the gear ring 1907, the telescopic rod 1905 is equidistantly distributed around the ring plate 1904, and the ring plate 1904 rotates with the lower shell 1 through the annular groove 1902 The rotating ring 1906 and the gear ring 1907 rotate in the rotating groove 1901, and the rotating ring 1906 and the gear ring 1907 are slidably connected to the lower shell body 1 through the rotating groove 1901. The clamping assembly 19 also includes a clamping groove 1908, a push rod 1909 and a clamping plate 1910. The inner wall of the rotating ring 1906 is symmetrically provided with clamping grooves 1908, and the push rod 1909 is fixedly connected in the clamping groove 1908. The other end of the push rod 1909 is fixedly connected to the clamping plate 1910, and the clamping plate 1910 is arc-shaped. The clamping assembly 19 also includes a driving cavity 1911, a motor 1912 and a driving wheel 1913. A driving cavity 1911 is provided on one side of the rotating groove 1901, and the motor 1912 is fixedly connected in the driving cavity 1911. The upper end of the motor 1912 is fixedly connected to the driving wheel 1913, and the driving wheel 1913 is engaged with the gear ring 1907. The specific operation is as follows: after the stator is placed in the placement chamber 6, the push rod 1909 pushes the clamping plate 1910 out of the clamping groove 1908, so that the clamping plate 1910 clamps the stator. After the clamping is firm, the telescopic rod 1905 drives the rotating ring 1906 to rise in the rotating groove 1901, so that the bottom end of the stator is out of contact with the placement chamber 6, to avoid damage caused by friction between the stator and the inner wall of the placement chamber 6 during cleaning. During cleaning, the motor 1912 starts to drive the driving wheel 1913 to rotate, which can drive the rotating ring 1906 to rotate in the rotating groove 1901 through the gear ring 1907, so that the stator rotates in the placement chamber 6, and the stator is fully cleaned. At the same time, the rotating ring 1906 drives the ring plate 1904 to rotate in the ring groove 1902 through the telescopic rod 1905, and the ball 1903 can assist the rotating ring 1906 and the ring plate 1904 in the rotating groove 1901 and the ring groove 1902. When the stator is lowered and clamped, the motor 1912 stops running to avoid damage caused by friction between the stator and the inner wall of the placement cavity 6. In summary, the stator can be clamped and adjusted during cleaning to ensure the cleaning effect, and it can be inspected after cleaning to avoid glycerin remaining on the stator.

[0025] In summary, when using the motor stator dust removal tool with auxiliary components, first put the stator into the placement cavity 6, then push the rod 1909 to push the clamping plate 1910 out of the clamping groove 1908, so that the clamping plate 1910 clamps the stator. After the clamping is firm, the telescopic rod 1905 drives the rotating ring 1906 to rise in the rotating groove 1901, so that the bottom end of the stator is separated from the contact with the placement cavity 6, avoiding damage caused by friction between the stator and the inner wall of the placement cavity 6 during cleaning. The lifting rod 2 lowers the upper shell 301 to fit tightly between the lower shell 1 and the upper shell 301, completely covering the stator. During the lowering process of the upper shell 301, the sealing ring 302 is stuck The stator is placed in a sealed environment to prevent dust and dirt from spreading into the air during dust removal, thereby affecting the air quality in the workshop and preventing damage to the stator due to collision with the stator during the cleaning process. When cleaning the stator, the vacuum pump 13 is started, the electromagnetic valve 307 in the air inlet 305 is opened, and the electromagnetic valve 307 in the liquid inlet 306 is closed. The outside air can enter the uniform distribution chamber 303 from the air inlet 305 and be sprayed toward the stator through the nozzle 304 to perform the initial cleaning of the stator. The dust adhering to the upper part is blown down, and the air flow carries the dust from the placement chamber 6 into the storage chamber 7. After the dust is trapped in the dust box 8 by the filter 9, the air enters the outlet pipe 11 from the storage chamber 7 through the shunt pipe 10, and is then extracted by the vacuum pump 13. After the initial cleaning is completed, the electromagnetic valve 307 in the air inlet 305 and the liquid inlet 306 switches the open and closed state, and the vacuum pump 13 continues to run, so that the glycerin in the liquid storage tank 18 can be drawn into the uniform distribution chamber 303 from the liquid inlet 306, and sprayed onto the stator through the nozzle 304 for secondary cleaning, so as to dissolve and rinse the dust and stains that are more firmly attached to the stator, and the glycerin carrying the stains is removed from the placement chamber 6 enters the storage chamber 7, and after the stains are trapped in the dust box 8 by the filter 9, the glycerin enters the shunt pipe 10 from the storage chamber 7. The diaphragm 12 can block the glycerin. The diaphragm 12 is a selective permeable membrane, and glycerin cannot pass through the diaphragm, preventing glycerin from entering the outlet pipe 11 while only allowing air to enter the outlet pipe 11. After the glycerin in the liquid storage tank 18 is extracted, a negative pressure is formed inside, and the glycerin in the shunt pipe 10 can be recovered into the liquid storage tank 18 through the outlet pipe 14 under the action of the negative pressure. When the glycerin is extracted, the air between the lower shell 1 and the upper shell 301 will enter the shunt pipe 10 and the outlet pipe 11, and the extracted glycerin falls into the shunt pipe 10. The bottom enters the position of the liquid outlet pipe 14, forming a liquid seal effect. As the air between the lower shell 1 and the upper shell 301 flows out, the pressure is reduced, and the glycerin in the liquid storage tank 18 is sucked out, which reduces the pressure in the liquid storage tank 18 and sucks the glycerin in the liquid outlet pipe 14 up. The solenoid valve 307 in the air inlet 305 is intermittently opened to replenish the air between the lower shell 1 and the upper shell 301. Because the diverter pipe 10 and the air outlet pipe 11 are replenished with air,The pressure in the liquid storage tank 18 is lower than the pressure in the shunt pipe 10. Before the glycerin flows back to the liquid storage tank 18, the purifier 17 can purify the glycerin to keep it clean and prevent dust from adhering to the stator after cleaning. When the upper shell 301 is raised or lowered, the liquid outlet pipe 14 can slide in the connecting pipe 16 to maintain the connection between the liquid outlet pipe 14 and the connecting pipe 16 to prevent glycerin leakage. The one-way valve 15 can control the flow direction of glycerin to prevent glycerin from flowing back from the liquid outlet pipe 14 to the shunt pipe 10. When cleaning, the electric When the machine 1912 is started and the driving wheel 1913 is rotated, the rotating ring 1906 is driven to rotate in the rotating groove 1901 through the gear ring 1907, so that the stator rotates in the placement cavity 6, and the stator is fully cleaned. At the same time, the rotating ring 1906 drives the ring plate 1904 to rotate in the ring groove 1902 through the telescopic rod 1905, and the ball 1903 can assist the rotating ring 1906 and the ring plate 1904 to rotate in the rotating groove 1901 and the ring groove 1902 to ensure their smooth rotation. In the cleaning process, the telescopic rod 1905 can first move the rotating ring 1906 and the ring plate 1904 to rotate in the rotating groove 1901 and the ring groove 1902. 06 is lowered to release the clamping of the stator. After the swivel 1906 rotates 90°, the stator is clamped again and the clamping point is switched to clean the clamping point to ensure the cleaning effect. When the stator is lowered and clamped, the motor 1912 stops running to avoid damage caused by friction between the stator and the inner wall of the placement chamber 6. After the second cleaning is completed, the solenoid valve 307 in the liquid inlet 306 is closed, and the air pump 13 continues to run to pump the placement chamber 6 into a negative pressure to accelerate the volatilization of glycerin. At the same time, the solenoid valve 307 in the air inlet 305 is intermittent. The stator is opened to allow air to be intermittently sprayed from the nozzle 304 toward the stator. While maintaining negative pressure, the volatilized glycerin is sent out of the storage chamber 6, thereby removing the glycerin on the stator surface and preventing glycerin from remaining on the stator. When removing the glycerin, the stator surface can be energized through the clamping plate 1910, and the windings on the stator can be tested for power. If glycerin remains on the stator, current will flow through the windings. If no current is detected on the windings, it means that the glycerin has been completely removed. After cleaning is completed, the dust box 8 can be pulled out of the storage chamber 7 for cleaning.
