Description

Technical Field

[0001] This invention relates to the field of electric tricycle manufacturing technology, specifically to a sealing device and method for the motor housing of an electric tricycle. Background Technology

[0002] Electric tricycles are three-wheeled vehicles that use batteries as their power source and are driven by motors. The motor is the core power component, which converts the electrical energy output by the battery into mechanical energy to drive the vehicle. In order to ensure the performance and safety of the motor during the production process, the motor housing needs to be sealed. In the production of motors, in order to ensure their performance and safety, the motor housing needs to be sealed. The traditional method is to use sealant or gaskets for static parts and assemble skeleton oil seals at the dynamic shaft extension ends.

[0003] When encapsulating the motor housing, the motor housing and end cap are mostly formed using aluminum alloy die casting. The die casting agent, release agent and other additives used in the die casting stage will leave oil stains on the aluminum alloy surface. In addition, metal debris (such as burrs and flash) that is not thoroughly cleaned after die casting, as well as the oxide layer that naturally forms on the metal surface, will directly damage the flatness of the sealing surface. This makes it impossible for the sealing ring to fully fit the sealing surface during subsequent assembly. During the curing process of the sealant, impurities can also easily cause bubbles and delamination, which seriously affects the sealing reliability of the motor housing. Secondly, due to the differences in load, power and body size, different specifications of electric tricycles are equipped with motors of vastly different sizes. When producing different batches of motors, and dealing with frequent changes in motor specifications, not only is it necessary to manually operate multiple adjustment links, but there is also a lack of rapid adaptation capability, which leads to excessive adjustment time and slows down the production rhythm. In order to solve the above problems, the inventor proposes an electric tricycle motor housing sealing device and method to solve the above problems. Summary of the Invention

[0004] In order to solve the problems of cleanliness of the sealing surface of the motor housing and end cover, as well as the adjustment efficiency when producing motors of different specifications, the present invention aims to provide a sealing device and method for the motor housing of an electric tricycle.

Two symmetrically distributed push rods are rotatably arranged at both ends of the sliding plate, and the other end of the push rod is fixedly connected to the corresponding adjustment plate by bolts. An electric cylinder is fixedly installed at the top center of the central frame, and the driving end of the electric cylinder is fixedly connected to the sliding plate.

[0008] Preferably, the heat exchange self-cleaning assembly includes two symmetrically distributed heat exchange frames and several heat exchange tubes arranged in a ring array. The heat exchange tubes are located between the two heat exchange frames, with both ends of each tube connected through to the two heat exchange frames. A sleeve is fitted between the two heat exchange frames, with both ends of the sleeve fixedly connected to the outer wall of the corresponding heat exchange frame. The sleeve is fixedly installed at the bottom of the central frame via an external frame. A fan is fixedly installed on one side of the support, and the fan's outlet is connected to the air inlet at the bottom of the sleeve via a duct. The middle of the outer wall of both hollow conveyor shafts... The rotating sleeve is equipped with a conveying frame, and the outer wall of the conveying frame is firmly connected to the connecting frame through a support plate. The air inlet of the conveying frame away from the fan is connected to the air outlet at the top of the sleeve through an air duct. A high-pressure steam generator is installed on the outside of the support. The exhaust end of the high-pressure steam generator is connected to the air inlet pipe of the adjacent heat exchange frame through an air duct.

The bottom end of the air inlet is connected to the exhaust port of the adjacent hollow conveyor shaft through a flexible hose.

[0010] A method for using a sealing device for the housing of an electric tricycle motor includes the following steps:

[0011] S1. First, aluminum alloy sheets are die-cast into the motor housing and end cap of an electric tricycle using a die-casting machine. Then, an external clamping and conveying device clamps and fixes the formed parts to ensure that the motor housing and end cap are vertically and accurately aligned.

[0012] S2. The external clamping device drives the motor housing and end cover to move along the guide rail to the corresponding degreasing station of the bracket. The high-pressure steam generated by the high-pressure steam generator is sprayed in a direction to remove the grease and impurities on the surface of the contact surface.

[0013] S3. Then, the cleaned motor housing and end cover are moved to the polishing area. The six adjustable polishing brushes start rotating and polishing. At the same time, the internal air ducts discharge high-temperature gas, which blows away the generated debris during the polishing process.

[0014] S4. High-speed airflow and residual high-pressure steam exchange heat during the transportation process, causing the high-speed airflow to heat up and turn into high-pressure warm air, which cleans up the grinding debris and dries the motor housing and end cover at the same time.

[0015] S5. After the motor housing and end cover are processed, the external robotic arm will accurately install the internal components of the motor into place. Then, a sealing coil will be placed on the contact surface between the housing and the end cover, and sealant will be applied evenly at the corresponding position. Finally, the end cover will be driven to descend vertically by the external clamping and conveying device and accurately dock with the motor housing to complete the sealing assembly of the motor housing.

[0016] S6. When producing motor housings of different specifications, the automatic adjustment component can synchronously adjust the position of multiple sets of adjustment blocks to meet the processing requirements of different specifications.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention, by setting up a synchronous rotation component and a heat exchange self-cleaning component, enables the synchronous rotation component to drive the nozzle and the grinding brush to rotate synchronously. High-pressure steam is used to remove grease and impurities, and the grinding brush removes burrs. At the same time, the heat exchange self-cleaning component allows the high-pressure steam and the airflow to complete heat exchange, so that the high-speed airflow is heated and discharged. The hot air dries the workpiece while blowing away grinding debris, ensuring that the sealing surface is clean and flat, effectively reducing the risk of seal failure, improving the stability of the sealing performance of the motor housing, and meeting the needs of long-term use.

[0019] 2. This invention, by setting up an automatic adjustment component, enables the equipment to synchronously adjust the centripetal distance of multiple adjustment blocks during operation, thereby adjusting the positions of high-pressure steam injection, grinding, and exhaust, adapting to the processing needs of motor housings of different specifications. This solves the problems of multiple manual adjustment steps, long time consumption, and poor adaptability when specifications are frequently changed, ensuring production rhythm.

[0020] 3. By setting up a grinding replacement component, when the grinding brush needs to be replaced, the limit bolt can be manually pulled to disengage it from the limit groove, making it easy to remove the plug block and the grinding brush. When installing a new grinding brush, after inserting the plug block, the limit bolt will automatically lock into the limit groove under the action of the return spring to complete the fixation. This allows for timely replacement of vulnerable parts to ensure grinding quality and effectively improves the maintenance efficiency and processing adaptability of the equipment.

[0040] The heat exchange self-cleaning component 5 includes two symmetrically distributed heat exchange frames 501 and several heat exchange tubes 502 arranged in a ring array. The heat exchange tubes 502 are located between the two heat exchange frames 501, and both ends of the heat exchange tubes 502 are respectively connected to the two heat exchange frames 501. A sleeve 503 is sleeved between the two heat exchange frames 501, and both ends of the sleeve 503 are respectively fixedly connected to the outer wall of the corresponding heat exchange frame 501.

[0041] By adopting the above technical solution, the two hollow conveyor shafts 301 can still synchronously adjust the centripetal movement of multiple sets of adjusting blocks 403 during rotation, thereby realizing the adjustment of the high-pressure steam injection point, grinding position and exhaust position, and adapting to the processing of motor housings of different specifications.

[0042] Two connecting frames 2 are each secured with a side frame 406 by bolts on their outer sides. A central frame 407 is secured between the two connecting frames 2 by bolts.

A servo motor 305 is fixedly installed on one side of the top of the central frame 407, and the drive end of the servo motor 305 is connected to the two hollow conveying shafts 301 through a synchronous pulley transmission group.

[0045] By adopting the above technical solution, the two hollow conveyor shafts 301 are made to rotate synchronously under the action of the synchronous wheel transmission group.

[0046] A sliding plate 408 is slidably mounted on the top center of the central frame 407 via a slide rail. Two symmetrically distributed push rods 409 are respectively mounted on both ends of the sliding plate 408, and the other end of the push rods 409 is securely connected to the corresponding adjustment plate 405 by bolts.

[0047] By adopting the above technical solution, the sliding plate 408 can move by pushing rod 409 to drive the two adjusting plates 405 to move closer or further apart.

[0048] The sleeve 503 is fixedly installed at the bottom of the central frame 407 by the external frame. A fan 505 is fixedly installed on one side of the bracket 1, and the air outlet of the fan 505 is connected to the air inlet at the bottom of the sleeve 503 through the air duct. The middle of the outer wall of the two hollow conveying shafts 301 is rotatably fitted with a conveying frame 504, and the outer wall of the conveying frame 504 is firmly connected to the connecting frame 2 through the support plate. The air inlet of the conveying frame 504 on the side away from the fan 505 is connected to the air outlet at the top of the sleeve 503 through the air duct.

[0049] By adopting the above technical solution, the fan 505 generates a high-speed airflow that enters the sleeve 503 for circulation and comes into contact with the heat exchange tube 502 to generate a high-temperature airflow.

[0050] A high-pressure steam generator 506 is provided on the outside of the bracket 1.

[0057] By adopting the above technical solution, the electric cylinder 410 pushes the sliding plate 408 to move.

[0058] A method for using a sealing device for the housing of an electric tricycle motor includes the following steps:

[0059] S1. First, aluminum alloy sheets are die-cast into the motor housing and end cap of an electric tricycle using a die-casting machine. Then, an external clamping and conveying device clamps and fixes the formed parts to ensure that the motor housing and end cap are vertically and accurately aligned.

[0060] S2. The external clamping device drives the motor housing and end cover to move along the guide rail to the corresponding degreasing station of the bracket 1. The high-pressure steam generated by the high-pressure steam generator 506 is sprayed in a directional manner to remove the grease and impurities on the surface of the contact surface.

[0061] S3. Then, the cleaned motor housing and end cover are moved to the polishing area. The six adjustable polishing brushes 602 start to rotate and polish. At the same time, the internal air ducts discharge high-temperature gas, which blows away the generated debris during the polishing process.

[0062] S4. High-speed airflow and residual high-pressure steam exchange heat during the transportation process, causing the high-speed airflow to heat up and turn into high-pressure warm air, which cleans up the grinding debris and dries the motor housing and end cover at the same time.

[0063] S5. After the motor housing and end cover are processed, the external robotic arm will accurately install the internal components of the motor into place. Then, a sealing coil will be placed on the contact surface between the housing and the end cover, and sealant will be applied evenly at the corresponding position. Finally, the end cover will be driven to descend vertically by the external clamping and conveying device and accurately dock with the motor housing to complete the sealing assembly of the motor housing.

[0064] S6. When producing motor housings of different specifications, the automatic adjustment component can synchronously adjust the position of multiple sets of adjustment blocks 403 to meet the processing requirements of different specifications.

[0065] Working principle: In actual use, such as Figure 1 As shown, the external clamping device drives the motor housing and end cover to move along the guide rail to the corresponding degreasing station of bracket 1. Then, as... Figure 8 As shown, the servo motor 305 is started. The servo motor 305 drives the two hollow conveyor shafts 301 to rotate stably and synchronously under the action of the guide ring 303 and the pulley group 304 via the synchronous pulley transmission group. Simultaneously, as... Figure 9 , Figure 10 As shown, the high-pressure steam generator 506 is simultaneously activated. The high-pressure steam generated by the high-pressure steam generator 506 is guided by the gas pipe and discharged into the corresponding conveying frame 504 through the heat exchange frame 501 and heat exchange pipe 502. Figure 4 As shown, the high-pressure steam in the conveying frame 504 enters the hollow conveying shaft 301 and is then conveyed to the nozzle 507 through the exhaust ports at both ends and the hose. The nozzle 507 is set at an angle, and the steam is sprayed out at an angle through the nozzle 507 and cooperates with the rotation of the hollow conveying shaft 301 to clean the oil stains and impurities on the contact surface between the motor housing and the end cover.

[0066] After cleaning, the external clamping device moves the motor housing and end cover along the guide rail to the grinding station. Simultaneously, another set of external clamping devices follows the same steps to send the corresponding motor housing and end cover into the degreasing station, forming a continuous operation process and improving overall processing efficiency. Then, the blower 505 is turned on, generating airflow that enters the sleeve 503, where it exchanges heat with the high-pressure steam in the heat exchange frame 501 and heat exchange tube 502, forming a high-temperature airflow. This high-temperature airflow passes through the air duct and the corresponding conveyor frame 504 and hollow conveyor shaft 301, such as... Figure 6As shown, the high-temperature airflow is accelerated and split through the conical air delivery hole 508 and then discharged through the exhaust hole 509. During the rotation of the hollow conveyor shaft 301, the grinding brush 602 rotates synchronously to grind the burrs off the adjacent side of the motor housing and end cover. The hot air blows away the grinding debris and dries the dry workpiece, removing the water droplets generated by the high-pressure steam.

[0067] When processing motor housings of different specifications, such as Figure 7 As shown, the electric cylinder 410 extends or retracts, and the electric cylinder 410 pushes the sliding plate 408 to move along the slide rail. The sliding plate 408 drives the adjusting plate 405 to slide vertically along the slide rail with the help of the push rod 409, so that the two adjusting plates 405 move closer or further away from each other. The adjusting plate 405 drives the adjusting frame 401 to rise or fall synchronously through the adjusting ring 402. The adjusting frame 401 pushes and pulls the adjusting block 403 through the connecting rod 404, so that the six adjusting blocks 403 of the four sets corresponding to each other move synchronously closer or further away from each other along the adjusting frame 302, which can be adapted to different specifications of motor housings and adjust the positions of high-pressure steam injection, grinding, exhaust, etc.

[0068] When the polishing brush 602 needs to be replaced, the machine must be stopped and the limit pin 603 must be manually pulled to compress the return spring 604 so that the limit pin 603 is completely disengaged from the limit groove 605. Then the plug block 601 can be pulled out to complete the disassembly. Similarly, after the new plug block 601 is inserted, the limit pin 603 will be locked into the limit groove 605 under the elastic force of the return spring 604, so as to achieve quick replacement.

[0069] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.

9. The method used in the sealing device for the motor housing of an electric tricycle as described in any one of claims 1-8, characterized in that, Includes the following steps: S1. First, aluminum alloy sheets are die-cast into the motor housing and end cap of an electric tricycle using a die-casting machine. Then, an external clamping and conveying device clamps and fixes the molded parts to ensure that the motor housing and end cap are vertically and accurately aligned. S2. The external clamping device drives the motor housing and end cover to move along the guide rail to the corresponding degreasing station of the bracket (1). The high-pressure steam generated by the high-pressure steam generator (506) is sprayed in a directional manner to remove the grease and impurities on the surface of the contact surface. S3. Then, the cleaned motor housing and end cover are moved to the polishing area. The six adjustable polishing brushes (602) start rotating and polishing. At the same time, the internal air ducts discharge high-temperature gas, which blows away the generated debris during the polishing process. S4. High-speed airflow and residual high-pressure steam exchange heat during the transportation process, causing the high-speed airflow to heat up and turn into high-pressure warm air, which cleans up the grinding debris and dries the motor housing and end cover at the same time. S5. After the motor housing and end cover are processed, the external robotic arm will precisely install the internal components of the motor into place. Then, a sealing coil will be placed on the contact surface between the housing and the end cover, and sealant will be applied evenly at the corresponding position. Finally, the end cover will be driven to descend vertically by the external clamping and conveying device and precisely docked with the motor housing to complete the sealing assembly of the motor housing. S6. When producing motor housings of different specifications, the automatic adjustment component can synchronously adjust the position of multiple sets of adjustment blocks (403) to meet the processing requirements of different specifications.
