[0053] Combine the following Figure 1-Figure 17 The cleaning device 10 according to the embodiment of the present invention is described in detail.

[0054] Reference Figure 1-Figure 3 As shown, according to the cleaning device 10 of the embodiment of the utility model, it is used to clean the cooling channel 201 of the motor housing 20. The cleaning device 10 includes: a clamp assembly 1, the clamp assembly 1 includes: a driving member 11, an actuator 12 and a sealing member 13, the driving member 11 is connected to the actuator 12, the driving member 11 is used to drive the actuator 12 to move, the actuator 12 has a cleaning channel 121, the sealing member 13 is detachably connected to the actuator 12, the sealing member 13 has a connecting channel 132, one end of the connecting channel 132 is connected to the cleaning channel 121, and the other end of the connecting channel 132 is suitable for connecting with the cooling channel 201.

[0056] It can be understood that when cleaning the cooling channel 201 of the motor housing 20, the motor housing 20 can be fixed, and the liquid inlet of the cooling channel 201 is opposite to the end of the connecting channel 132 away from the cleaning channel 121, and the driving member 11 can drive the actuator 12 to move in the direction close to the motor housing 20 so that the sealing member 13 fits the motor housing 20. At this time, one end of the connecting channel 132 is connected to the cleaning channel 121, and the other end of the connecting channel 132 is connected to the liquid inlet of the cooling channel 201 and connected, and the cleaning medium can pass through the cleaning channel 121 in sequence. 1 and the connecting flow channel 132 enter the liquid inlet of the cooling flow channel 201, and the cleaning medium flows out from the liquid outlet of the cooling flow channel 201 after flowing through the cooling flow channel 201, so that the impurities in the cooling flow channel 201 flow out of the cooling flow channel 201 together with the cleaning medium, thereby cleaning the cooling flow channel 201 and removing the impurities in the cooling flow channel 201. After the cooling flow channel 201 is cleaned, the driving member 11 can drive the actuator 12 to move in a direction away from the motor housing 20, so that the sealing member 13 is separated from the motor housing 20, and then the cleaned motor housing 20 is taken out.

[0057] When motors of different models are produced on the same line, motor housings 20 of different models need to be used, and the cooling channel 201 of each model of motor housing 20 needs to be cleaned. For motor housings 20 of different models, the positions of the liquid inlets of the cooling channels 201 are different. In the cleaning device 10 of the embodiment of the utility model, the seal 13 and the actuator 12 are detachably connected, so that the cleaning device 10 can be adapted to motor housings 20 of different models by replacing the seal 13, which is beneficial to improving the versatility of the cleaning device 10. At the same time, the operation of replacing the seal 13 is simple and convenient, which is beneficial to improving the production efficiency of the production line.

[0058] Specifically, the clamp assembly 1 may have various types of seals 13, and the various types of seals 13 are adapted one-to-one with the various types of motor housings 20. When the cleaning device 10 cleans the cooling channels 201 of motor housings 20 of different types, the seals 13 on the actuator 12 can be removed and replaced, so that the connecting channel 132 of the replaced seal 13 is adapted and connected with the liquid inlet of the cooling channel 201 to be cleaned, thereby eliminating the need to remove and replace the actuator 12 or to remove the pipeline connected to the actuator 12 that provides the cleaning medium to the cleaning channel 121, thereby achieving rapid cleaning of motor housings 20 of different types, thereby helping to improve the production efficiency of the production line.

[0059] According to the cleaning device 10 of the embodiment of the utility model, it can be used to clean the cooling channels 201 of motor housings 20 of different models. When cleaning the cooling channels 201 of motor housings 20 of different models, the cleaning device 10 can remove and replace the sealing member 13 without removing and replacing the actuator 12. The cleaning device 10 needs to remove and replace fewer parts, which is beneficial to reduce the time required for disassembly and replacement of parts and is beneficial to improving the production efficiency of the production line.

[0060] In some embodiments of the present invention, referring to Figure 1 As shown, the actuator 12 is provided with a positioning pin, and the sealing member 13 is provided with a positioning hole 131. The positioning hole 131 cooperates with the positioning pin to achieve accurate positioning of the sealing member 13, thereby avoiding misalignment between the cleaning channel 121 of the actuator 12 and the connecting channel 132 of the sealing member 13, thereby facilitating the connection between the cleaning channel 121 and the connecting channel 132.

[0061] Reference Figure 1 As shown, the actuator 12 is provided with a plurality of positioning pins, and the seal 13 is provided with a plurality of positioning holes 131. The plurality of positioning pins correspond to the plurality of positioning holes 131 one by one, and the plurality of positioning pins can form a plurality of positioning groups with the plurality of positioning holes 131, thereby facilitating the improvement of the positioning effect of the seal 13 and realizing the precise positioning of the seal 13.

[0062] In some embodiments of the present invention, there are multiple clamp assemblies 1, and the actuators 12 of at least two clamp assemblies 1 are arranged relatively to each other in a first direction. When cleaning the cooling channel 201 of the motor housing 20, in the first direction, the two clamp assemblies 1 can clamp the motor housing 20 together to prevent the motor housing 20 from shaking during the cleaning process. At the same time, the connecting channels 132 of the seals 13 of the two clamp assemblies 1 can be respectively connected to the two liquid inlets on the cooling channel 201, and the cleaning medium can enter the cooling channel 201 through the two liquid inlets, which is beneficial for the cleaning medium to flow through the entire cooling channel 201 to fully clean the cooling channel 201, thereby helping to improve the cleaning effect of the cooling channel 201.

[0063] It should be noted that when the cooling channel 201 has a bypass port, when the seal 13 is in contact with the motor housing 20, the seal 13 is also suitable for blocking the bypass port of the cooling channel 201 to prevent the cleaning medium in the cooling channel 201 from flowing out through the bypass port, so as to ensure that the cleaning medium flows through the entire cooling channel 201, thereby helping to improve the cleaning effect.

[0064] In some embodiments of the present invention, referring to Figure 1 and Figure 2 As shown, the fixture assembly 1 also includes: a blocking block 14, which is detachably connected to the sealing member 13, and can be used to block the bypass port on the motor housing 20. During the cleaning process of the cooling channel 201, the cleaning medium in the cooling channel 201 can be prevented from flowing out through the bypass port, and the cleaning medium can be ensured to flow out from the liquid outlet, so that the cleaning medium can flow through the entire cooling channel 201, thereby facilitating the cleaning effect. The blocking block 14 can be detachably connected to the sealing member 13 by a fastener, and the fastener can be a screw.

[0065] It can be understood that the blocking block 14 is detachably connected to the seal 13. When cleaning motor housings 20 of different models, the blocking block 14 can be replaced to block the bypass ports on different motor housings 20, thereby avoiding the need to disassemble and replace the seal 13, which is beneficial to improving the production efficiency of the production line.

[0066] In some embodiments of the present invention, referring to Figure 1 and Figure 4-Figure 7 As shown, the fixture assembly 1 also includes: a guide member 15, the guide member 15 is detachably connected to the sealing member 13, the guide member 15 has a guide channel, the connecting channel 132 is suitable for communicating with the cooling channel 201 through the guide channel, the inlet of the guide channel and the outlet of the guide channel are at least partially staggered to change the position where the cleaning medium flows out, and the outlet of the guide channel can correspond to the liquid inlet of the cooling channel 201, so as to facilitate the connection of the connecting channel 132 with the cooling channel 201 through the guide channel, so as to facilitate the fixture assembly 1 to adapt to motor housings 20 of different models. Among them, the guide member 15 can be detachably connected to the sealing member 13 through a fastener, and the fastener can be a screw.

[0067] It can be understood that when the cleaning device 10 cleans the cooling channel 201 of motor housings 20 of different models, the guide member 15 can be installed on the seal 13, and the cleaning water pipe can be connected to the cooling channel 201 of the motor housing 20 through the cleaning channel 121, the connecting channel 132 and the guide channel in sequence, and the cleaning medium can flow into the cooling channel 201 through the washing channel, the connecting channel 132 and the guide channel in sequence to clean the cooling channel 201, without the need to disassemble and replace the seal 13, which is beneficial to improving the production efficiency of the production line.

[0068] In addition, the blocking block 14 is detachably connected to the sealing member 13 to facilitate the flexible use of the blocking block 14. When the cleaning device 10 cleans the cooling channel 201 of the motor housing 20 of different models, the blocking block 14 can be removed before the guide member 15 is installed on the sealing member 13 to avoid interference between the blocking block 14 and the guide member 15. The sealing member 13 does not need to be processed to avoid the groove of the blocking block 14, thereby avoiding interference between the groove and the guide channel, which is beneficial to the design and processing of the guide channel of the seal 13.

[0069] In other embodiments of the present invention, referring to Figure 4-Figure 7 As shown, the guide member 15 has a guide groove 151 opening toward the seal 13. After the guide member 15 is connected to the seal 13, the guide groove 151 can jointly define a guide channel with the seal 13. The connecting channel 132 is suitable for being connected to the cooling channel 201 through the guide channel. In the first direction, the inlet of the guide channel and the outlet of the guide channel are at least partially staggered.

[0070] In some embodiments of the utility model, the seal 13 and the guide 15 are both made of polyurethane material. The sealing performance of polyurethane is good, which is conducive to improving the sealing performance of the seal 13 and the guide 15 at the connection. When the cleaning medium in the cooling channel 201 flows to the guide channel, it can avoid leakage of the cleaning medium at the connection between the seal 13 and the guide 15, thereby ensuring the flow rate of the cleaning medium flowing from the guide channel to the cooling channel 201, and improving the cleaning effect. In addition, the cost of polyurethane is relatively low, which is conducive to saving the manufacturing cost of the cleaning device 10. Polyurethane also has good processability, which is convenient for processing and manufacturing of the seal 13 and the guide 15.

In addition, the driving member 11 of the clamp assembly 1 can be installed on the support plate 2 to improve the integration of the cleaning device 10.

[0072] In some embodiments of the present invention, referring to Figure 1 As shown, the support plate 2 has a positioning portion 22, and the motor housing 20 is suitable for positioning and cooperating with the positioning portion 22 to achieve the positioning of the motor housing 20, ensuring that the motor housing 20 is in a preset position, which is conducive to the connecting channel 132 being directly or indirectly connected with the cooling channel 201, so as to facilitate cleaning of the cooling channel 201 of the motor housing 20.

[0073] Reference Figure 1As shown, the positioning portion 22 includes a plurality of pins 221, and the pins 221 are suitable for positioning and cooperating with the positioning holes 131 on the motor housing 20 to accurately position the motor housing 20 and ensure that the motor housing 20 is fixed at a preset position on the support surface 21. At the same time, during the cleaning process of the motor housing 20, the positioning and cooperation between the pins 221 and the positioning holes 131 can prevent the motor housing 20 from sliding relative to the support plate 2.

[0074] In some embodiments of the utility model, the cleaning device 10 also includes: a manipulator, which is suitable for placing and removing the motor housing 20 from the support surface 21. The manipulator can replace manual operation of the motor housing 20, and there is no need for an operator to carry the motor housing 20, which helps to reduce the labor intensity of the operator.

[0075] It should be noted that the robot can also be used to block the bypass port on the cooling channel 201. During the cleaning process of the cooling channel 201 of the motor housing 20, the cleaning medium in the cooling channel 201 can be prevented from flowing out through the bypass port, and the cleaning medium can be ensured to flow out from the liquid outlet, so that the cleaning medium can flow through the entire cooling channel 201, thereby helping to improve the cleaning effect.

Among them, the actuator 31 can be a retractable mechanism such as a cylinder or a hydraulic cylinder, and the plugging member 32 can be a stainless steel plate or a polyurethane block.

[0077] In some embodiments of the present invention, the cleaning device 10 further includes a pumping assembly, which is connected to at least one cleaning channel 121. The pumping assembly is used to pump a cleaning medium to the cleaning channel 121 connected thereto to enhance the power of the cleaning medium flow, which is beneficial for the cleaning medium to flow in the cooling channel 201.
