Description

Technical Field

[0001] This invention relates to the field of motor housing technology, and in particular to a base housing for a new energy vehicle motor and its processing equipment. Background Technology

[0002] With the rapid popularization of new energy vehicle technologies such as plug-in hybrid, pure electric, and fuel cell vehicles, the electric motor, as a core power component, directly affects the vehicle's range and user experience through its operational stability and overall performance. The motor housing, as a key structure supporting and fixing the motor and ensuring its adaptability to various operating conditions, must simultaneously meet basic requirements such as mechanical strength, heat dissipation capacity, and environmental tolerance, making it a crucial aspect of new energy vehicle motor development.

[0003] In existing general-purpose motor housings, it is often difficult to balance lightweight design with core functions. Some housings, due to unreasonable material selection or structural design, are either too heavy, increasing the energy consumption burden of new energy vehicles, or have insufficient heat dissipation efficiency, making it difficult to meet the requirements of long-term stable operation of the motor, thus restricting the further improvement of the overall performance of new energy vehicle motors. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a base housing for a new energy vehicle motor and its processing equipment.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a base housing for a new energy vehicle motor, comprising a base cylinder and heat dissipation fins; the base cylinder is made of stainless steel and has a thickness of 1-4mm; multiple heat dissipation fins are provided and welded to the outer wall of the base cylinder, and the thickness of the heat dissipation fins is 1-3mm.

[0006] By adopting the above technical solution, the base cylinder and heat dissipation fins are made of stainless steel, which not only ensures the structural strength and corrosion resistance of the base housing, meeting the working environment requirements of new energy drive vehicle motors such as plug-in hybrid drive, pure electric drive, and fuel cell drive, but also effectively reduces the overall weight of the base housing by limiting the thickness of the base cylinder to 1-4mm and the thickness of the heat dissipation fins to 1-3mm. Compared with the base housings in existing general technologies, a lightweight design is achieved, which is conducive to reducing the overall energy consumption of new energy vehicles and improving the driving range. At the same time, multiple heat dissipation fins welded to the outer wall of the base cylinder significantly increase the heat dissipation area, and the reasonable thickness design ensures heat dissipation efficiency, which can ensure the long-term stable operation of the motor.

[0007] Furthermore, the base cylinder is provided with perforated through holes, and clearance openings are provided at the positions where the heat dissipation fins correspond to the perforated through holes.

[0008] By adopting the above technical solution, the hollow through hole provides a preset installation space for motor wiring, eliminating the need for subsequent additional hole drilling and simplifying the production process. At the same time, the heat dissipation fins are provided with clearance openings at positions corresponding to the hollow through hole, which not only prevents the heat dissipation fins from blocking the hollow through hole and ensures the smoothness of motor wiring operations, but also does not damage the overall arrangement and structural integrity of the heat dissipation fins, thus ensuring its original heat dissipation function.

[0009] Furthermore, a fixing lug is fixed to one end of the outer wall of the base cylinder.

[0010] By adopting the above technical solution, the fixing ear provides a reliable connection support point for the assembly of the base housing and the corresponding parts of the automobile, eliminating the need for additional fixing structures, simplifying the installation process of the new energy vehicle motor and improving assembly efficiency.

[0011] This application also discloses a processing equipment for the base housing of a new energy vehicle motor, including a base, a mounting base, a central cylinder, a connecting cylinder, a fixing mechanism, a material handling robot, and a welding robot; the mounting base is fixed to the top of the base, the central cylinder is disposed through the mounting base and is clearance-fitted with it, and the connecting cylinder is sleeved outside the central cylinder and rotatably connected to the mounting base; the fixing mechanism is disposed on both the central cylinder and the connecting cylinder and is used to fix the base housing from the inside; the material handling robot and the welding robot are both fixed to the top of the base, the material handling robot is used to grasp the heat dissipation fins to be welded, and the welding robot is used to weld the heat dissipation fins to the outer wall of the base housing.

[0012] By adopting the above technical solution, the fixing mechanism can be firmly fixed from the inside of the base cylinder, ensuring the stability of the heat dissipation fins during the welding process. The material handling robot and the welding robot work together to realize the automated operation of heat dissipation fin gripping and welding, reducing the workload of workers, effectively improving processing accuracy and production efficiency, simplifying the processing process, and adapting to the batch processing needs of new energy vehicle motor base housings.

[0013] Furthermore, the fixing mechanism includes a mounting assembly and an inner support assembly. The mounting assembly includes an annular connecting seat, an inner cylinder, and a shaped connecting plate. Two annular connecting seats are coaxially arranged with the connecting cylinder; one annular connecting seat is fixed to the end of the connecting cylinder furthest from the mounting seat. The inner side of the inner cylinder is fixed to the outer walls of both annular connecting seats, and the inner diameter of the inner cylinder is smaller than the inner diameter of the base cylinder. Two shaped connecting plates are fixed to the annular connecting seats and are symmetrically distributed. A drive assembly for controlling the reciprocating movement of the central cylinder along its axial direction is provided on the mounting seat. Multiple sets of inner support assemblies are evenly distributed around the central cylinder. Each set of inner support assemblies includes a linkage unit and an inner support unit. It includes a linkage plate, a connecting rod, and a linkage rod; the linkage plate is fixed to the outer wall of the central cylinder, the length direction of the connecting rod is parallel to the axial direction of the central cylinder, and the outer sides of the two irregularly shaped connecting plates are provided with notches for the connecting rod to slide back and forth radially along the central cylinder; the linkage rod is fixed to the connecting rod, and the linkage plate is provided with a through-hole for the linkage rod to slide and engage, so that the connecting rod can be controlled to move radially along the central cylinder during the movement of the central cylinder as the linkage plate moves axially; the inner support unit is composed of multiple inner support plates fixed to the connecting rod, and the inner cylinder is provided with arc-shaped through holes at the corresponding positions of the inner support plates for them to pass through. The outer surface of the inner support plate is an arc surface, and the axis of the arc surface coincides with the axis of the inner cylinder.

[0014] By adopting the above technical solution, the operator can control the central cylinder to reciprocate along its axis using the drive assembly. By utilizing the sliding fit between the inclined hole of the linkage plate and the linkage rod, the axial movement of the central cylinder is converted into the radial movement of the connecting rod along the central cylinder. This, in turn, drives the inner support plate to pass through the arc-shaped through hole of the inner cylinder to achieve inner support and fixation of the base cylinder (or allows multiple inner support plates to be simultaneously retracted into the inner cylinder and the base cylinder to be released). Multiple sets of evenly distributed inner support components, combined with the inner support plate with the arc-shaped surface design, can fit tightly against the inner wall of the base cylinder, ensuring the structural stability of the base cylinder after it is fixed, and avoiding interference of the outer fixation with the welding area of ​​the outer wall of the base cylinder, thus ensuring the smooth progress of the heat dissipation fin welding operation.

[0015] Furthermore, the outer surface of the inner support plate is uniformly provided with multiple arc-shaped notches; the drive assembly includes a drive motor, a threaded rod, a guide rod, and a transmission plate. The drive motor is fixed on the mounting base, and the output shaft of the drive motor is parallel to the central cylinder; the threaded rod is fixed to the output end of the drive motor, the guide rod is fixed on the mounting base and is parallel to the threaded rod; the threaded rod passes through the transmission plate and is threadedly connected to it, the guide rod passes through the transmission plate and is slidably engaged with it, and the central cylinder passes through the transmission plate and is rotatably connected to it.

[0016] By adopting the above technical solution, the multiple arc-shaped recesses on the outer surface of the inner support plate increase the friction with the inner wall of the machine base cylinder, improving the anti-slip effect and stability of the inner support fixation. After the drive motor works, it drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the transmission plate, and the guide rod is slidably engaged with the transmission plate, the transmission plate reciprocates along the axial direction of the central cylinder, thereby driving the central cylinder fixed to the transmission plate and the linkage plate fixed to the central cylinder to move synchronously. Through the oblique hole on the linkage plate and the linkage rod on the connecting rod, the connecting rod moves radially along the central cylinder, thereby enabling multiple inner support plates to cooperate to achieve the operation of fixing or loosening the machine base cylinder together, ensuring the stability of the machine base cylinder during the welding process with the heat dissipation fins.

[0017] Furthermore, the end of the central cylinder furthest from the mounting base is closed. The annular connecting seat includes an inner ring fitted onto and adapted to the central cylinder, a radial pipe communicating with the inner ring, and an outer ring communicating with the radial pipe. Multiple air outlet holes are provided through the inner cylinder at positions corresponding to the outer ring on the side furthest from the mounting base, and multiple air return holes are provided through the inner cylinder at positions corresponding to the outer ring adjacent to the mounting base. A heating assembly is installed inside the central cylinder, comprising an outer pipe, an air outlet rotary joint, an inner pipe, and an air inlet rotary joint. The outer pipe is installed through the mounting base. It is rotatably connected to the outer tube, and its outer wall fits against the inner wall of the central tube; the air outlet rotary joint is connected to the outer tube, the inner tube passes through the air outlet rotary joint and is fixed to it, the outer wall of the inner tube is fixed to the inner wall of the outer tube, and the air inlet rotary joint is connected to the inner tube; an air inlet is provided through the central tube, and an air outlet is provided through the outer tube. The air inlet corresponds to the air outlet position when the inner support plate is pressed against the inner wall of the machine base tube; the central tube is provided with a sealing component for sealing both ends of the machine base tube when the inner support plate is pressed against the inner side of the machine base tube, and opening the end of the machine base tube when the inner support plate is away from the inner side of the machine base tube.

[0018] By adopting the above technical solution, the closed end of the central cylinder cooperates with the inner ring, radial tube, and outer ring of the annular connecting seat, and is matched with the inner tube, outer tube, and inlet / outlet rotary joint of the heating component. When the air inlet and outlet correspond, a stable airflow channel can be formed, allowing hot air to enter the inner cylinder through the air outlet and air inlet, and then act on the inner wall of the base cylinder through the air outlet hole. Finally, it flows back through the return air hole, realizing the circulating heating of the inner side of the base cylinder. This is beneficial for preheating before welding or heat preservation after welding, improving the welding strength of the heat dissipation fins and the base cylinder, avoiding weld cracking, and ensuring welding quality. The sealing assembly can seal both ends of the machine base cylinder during welding heating, ensuring heating efficiency and temperature uniformity. When picking up or placing workpieces, the ends of the machine base cylinder are left open, without affecting the loading and unloading operations. The rotary joint does not interfere with the relative movement of the central cylinder and the outer tube, adapting to the overall rotation and movement requirements of the equipment. The overall design optimizes the welding process environment, improves processing quality, and also takes into account ease of operation, further ensuring the stability and reliability of automated processing of new energy vehicle motor base housings.

[0019] Furthermore, the sealing assembly is provided with multiple sets evenly distributed around the central cylinder, including a fixed plate, diagonal rods, transmission rods, connecting blocks, and sealing plates. The fixed plate is fixed to the irregular connecting plate; one end of the diagonal rod is hinged to the fixed plate, and there are two diagonal rods that are parallel to each other. The transmission rod is fixed to one of the diagonal rods, and a slotted hole for sliding engagement of the transmission rod is provided through the connecting rod near its end; the connecting block is hinged to the ends of both diagonal rods, and one side of the sealing plate is fixed to the connecting block.

[0020] By adopting the above technical solution, the radial movement of the connecting rod drives the transmission rod to slide along the slotted hole, thereby driving the inclined rod to rotate around the hinge point of the fixed plate. The opening and closing action is achieved through the linkage of the connecting block and the sealing plate, without the need for additional drive structure, and synchronous linkage with the inner support assembly is realized. During welding heating, the sealing plate can tightly seal both ends of the machine base cylinder, ensuring the temperature uniformity and heating efficiency of the circulating heating in the inner cylinder, thereby improving the welding quality. When picking up and putting down workpieces, the sealing plate opens synchronously with the inner support assembly, without interfering with the loading and unloading operation of the machine base cylinder.

[0021] Furthermore, the mounting base is provided with a rotating assembly for driving the central cylinder to rotate. The rotating assembly includes a rotating motor, a driving gear, and a driven gear. The rotating motor is fixed on the mounting base, and the output shaft of the rotating motor is parallel to the central cylinder. The driving gear is fixedly sleeved on the output shaft of the rotating motor, and the driven gear is fixedly sleeved on the central cylinder and rotatably connected to the transmission plate. The driven gear meshes with the driving gear, and the thickness of the driving gear is greater than the thickness of the driven gear.

[0022] By adopting the above technical solution, after the rotating motor works, it drives the driving gear to rotate, thereby causing the driven gear meshing with it and the central cylinder fixed to the driven gear to rotate. This causes the base cylinder, which is fixed from the inside by the fixed mechanism, to rotate synchronously, so that the welding robot can weld the heat dissipation fins to different positions on the outer circumference of the base cylinder.

[0023] Furthermore, a scissor lift is fixed on the base, a fixed seat is fixed on the top of the scissor lift, rollers are rotatably mounted on the fixed seat, and a pushing robot is set on the side of the base away from the mounting seat.

[0024] By adopting the above technical solution, after the machine base cylinder to be processed is placed on top of the roller, the operator can control the lifting of the fixed seat and the roller through the scissor lift, thereby lifting the machine base cylinder. When the axis of the machine base cylinder reaches the height of the axis of the central cylinder, the operator can push the machine base cylinder to the outside of the inner cylinder by pushing the robot arm, so that the machine base cylinder can be fixed from the inside by the fixing mechanism.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. In this application, the base cylinder and heat dissipation fins are made of stainless steel, which not only ensures the structural strength and corrosion resistance of the base housing, meeting the working environment requirements of new energy drive vehicle motors such as plug-in hybrid drive, pure electric drive, and fuel cell drive, but also effectively reduces the total weight of the base housing by limiting the thickness of the base cylinder to 1-4mm and the thickness of the heat dissipation fins to 1-3mm. Compared with the base housing in existing general technology, a lightweight design is achieved, which is conducive to reducing the overall energy consumption of new energy vehicles and improving the driving range. At the same time, multiple heat dissipation fins welded to the outer wall of the base cylinder significantly increase the heat dissipation area, and the reasonable thickness design ensures heat dissipation efficiency, which can ensure the long-term stable operation of the motor.

[0027] 2. In this application, the operator can control the central cylinder to reciprocate along its axis by using the drive assembly. By utilizing the oblique hole of the linkage plate and the sliding engagement of the linkage rod, the axial movement of the central cylinder is converted into the radial movement of the connecting rod along the central cylinder, thereby driving the inner support plate to pass through the arc-shaped through hole of the inner cylinder to achieve inner support and fixation of the base cylinder (or allowing multiple inner support plates to simultaneously retract into the inner cylinder and loosen the base cylinder). Multiple sets of evenly distributed inner support components, combined with the inner support plate with the arc surface design, can fit tightly against the inner wall of the base cylinder, which not only ensures the structural stability of the base cylinder after it is fixed, but also avoids the interference of the outer fixation on the welding area of ​​the outer wall of the base cylinder, ensuring the smooth progress of the heat dissipation fin welding operation.

Detailed Implementation

[0040] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0041] like Figure 1-10 As shown in the embodiment of this application, a base housing for a new energy vehicle motor and its processing equipment are disclosed, including a base cylinder 1 and heat dissipation fins 2; the base cylinder 1 is made of stainless steel and has a thickness of 1-4mm; multiple heat dissipation fins 2 are provided and welded to the outer wall of the base cylinder 1, and the thickness of the heat dissipation fins 2 is 1-3mm.

[0042] The base cylinder 1 and heat dissipation fins 2 are made of stainless steel, which not only ensures the structural strength and corrosion resistance of the base housing, meeting the working environment requirements of new energy drive vehicle motors such as plug-in hybrid drive, pure electric drive, and fuel cell drive, but also effectively reduces the overall weight of the base housing by limiting the thickness of the base cylinder 1 to 1-4mm and the thickness of the heat dissipation fins 2 to 1-3mm. Compared with the base housing in existing general technology, it achieves a lightweight design, which is conducive to reducing the overall energy consumption of new energy vehicles and improving the driving range. At the same time, the multiple heat dissipation fins 2 welded to the outer wall of the base cylinder 1 significantly increase the heat dissipation area, and the reasonable thickness design ensures heat dissipation efficiency, which can ensure the long-term stable operation of the motor.

[0043] The base cylinder 1 is provided with a hollow through hole 1001, and the heat dissipation fins 2 are provided with clearance openings 21 at the corresponding positions of the hollow through hole 1001. The hollow through hole 1001 provides a pre-set installation space for motor wiring, eliminating the need for subsequent additional drilling and simplifying the production process; at the same time, the clearance openings 21 at the corresponding positions of the heat dissipation fins 2 not only prevent the heat dissipation fins 2 from obstructing the hollow through hole 1001, ensuring the smoothness of motor wiring operations, but also do not damage the overall arrangement and structural integrity of the heat dissipation fins 2, thus ensuring its original heat dissipation function.

[0044] A fixing lug 1002 is fixed to one end of the outer wall of the base cylinder 1. The fixing lug 1002 provides a reliable connection support point for the assembly of the base housing and the corresponding parts of the automobile, eliminating the need for additional fixing structures, simplifying the installation process of the new energy vehicle motor and improving assembly efficiency.

[0045] This application also discloses a processing equipment for the base housing of a new energy vehicle motor, including a base 3, a mounting base 4, a central cylinder 5, a connecting cylinder 6, a fixing mechanism 7, a material handling robot 31, and a welding robot 32; the mounting base 4 is fixed to the top of the base 3, the central cylinder 5 is disposed through the mounting base 4 and is clearance-fitted with it, the connecting cylinder 6 is sleeved on the outside of the central cylinder 5 and rotatably connected to the mounting base 4; the fixing mechanism 7 is disposed on the central cylinder 5 and the connecting cylinder 6, and is used to fix the base housing 1 from the inside; the material handling robot 31 and the welding robot 32 are both fixed to the top of the base 3, the material handling robot 31 is used to grasp the heat dissipation fins 2 to be welded, and the welding robot 32 is used to weld the heat dissipation fins 2 to the outer wall of the base housing 1.

[0046] The fixing mechanism 7 can be firmly fixed from the inside of the base cylinder 1, ensuring the stability of the heat dissipation fins 2 during the welding process. The material handling robot 31 and the welding robot 32 work together to realize the automated operation of grasping and welding the heat dissipation fins 2, reducing the workload of the staff, effectively improving the processing accuracy and production efficiency, simplifying the processing process, and adapting to the batch processing needs of new energy vehicle motor base housings.

[0047] The fixing mechanism 7 includes a mounting assembly 71 and an inner support assembly 72. The mounting assembly 71 includes an annular connecting seat 711, an inner cylinder 712, and a shaped connecting plate 713. The annular connecting seat 711 is coaxially arranged with the connecting cylinder 6, and there are two of them. One of the annular connecting seats 711 is fixed to the end of the connecting cylinder 6 away from the mounting base 4. The inner side of the inner cylinder 712 is fixed to the outer walls of both annular connecting seats 711, and the inner diameter of the inner cylinder 712 is smaller than the inner diameter of the base cylinder 1. The shaped connecting plate 713 is fixed to the annular connecting seat 711, and there are two of them, which are symmetrically distributed. The mounting base 4 is provided with a drive assembly 8 for controlling the reciprocating movement of the central cylinder 5 along its axial direction. The inner support assembly 72 is provided in multiple sets and evenly distributed around the central cylinder 5. Each set of inner support assembly 72 includes a linkage unit 721 and an inner support unit 722. The linkage unit 721 includes a linkage plate 7211, a connecting rod 7212, and a linkage rod. 7213; The linkage plate 7211 is fixed to the outer wall of the central cylinder 5. The length direction of the connecting rod 7212 is parallel to the axial direction of the central cylinder 5. Both irregular connecting plates 713 have notches 7131 on their outer sides for the connecting rod 7212 to slide radially back and forth along the central cylinder 5. The linkage rod 7213 is fixed to the connecting rod 7212. The linkage plate 7211 has a through-hole 72111 for the linkage rod 7213 to slide and engage, so that the linkage plate 7211 controls the connecting rod 7212 to move radially along the central cylinder 5 during the movement of the central cylinder 5 as the central cylinder 5 moves axially. The inner support unit 722 is composed of multiple inner support plates 7221 fixed to the connecting rod 7212. The inner cylinder 712 and the inner support plate 7221 are provided with arc-shaped through holes 7121 for them to pass through at the corresponding positions. The outer surface of the inner support plate 7221 is an arc surface, and the axis of the arc surface coincides with the axis of the inner cylinder 712.

[0048] The operator can control the central cylinder 5 to reciprocate along its axis by using the drive component 8. By utilizing the sliding engagement between the inclined hole 72111 of the linkage plate 7211 and the linkage rod 7213, the axial movement of the central cylinder 5 is converted into the radial movement of the connecting rod 7212 along the central cylinder 5. This, in turn, drives the inner support plate 7221 to pass through the arc-shaped through hole 7121 of the inner cylinder 712 to achieve inner support and fixation of the base cylinder 1 (or to allow multiple inner support plates 7221 to be simultaneously retracted into the inner cylinder 712 and release the base cylinder 1). Multiple sets of evenly distributed inner support components 72, combined with the arc-shaped inner support plate 7221, can fit tightly against the inner wall of the base cylinder 1, ensuring the structural stability of the base cylinder 1 after fixation and avoiding interference of the outer fixation with the welding area of ​​the outer wall of the base cylinder 1, thus ensuring the smooth progress of the welding operation of the heat dissipation fins 2.

[0049] The outer surface of the inner support plate 7221 is uniformly provided with multiple arc-shaped notches 72211; the drive assembly 8 includes a drive motor 81, a threaded rod 82, a guide rod 83, and a transmission plate 84. The drive motor 81 is fixed on the mounting base 4, and the output shaft of the drive motor 81 is parallel to the central cylinder 5; the threaded rod 82 is fixed to the output end of the drive motor 81, and the guide rod 83 is fixed on the mounting base 4 and parallel to the threaded rod 82; the threaded rod 82 passes through the transmission plate 84 and is threadedly connected to it, the guide rod 83 passes through the transmission plate 84 and is slidably engaged with it, and the central cylinder 5 passes through the transmission plate 84 and is rotatably connected to it.

[0050] Multiple arc-shaped notches 72211 on the outer surface of the inner support plate 7221 increase the friction with the inner wall of the base cylinder 1, improving the anti-slip effect and stability of the inner support fixation. After the drive motor 81 works, it drives the threaded rod 82 to rotate. Since the threaded rod 82 is threadedly connected to the transmission plate 84, and the guide rod 83 is slidably engaged with the transmission plate 84, the transmission plate 84 reciprocates along the axial direction of the central cylinder 5, thereby driving the central cylinder 5 fixed to the transmission plate 84 and the linkage plate 7211 fixed to the central cylinder 5 to move synchronously. Through the oblique hole 72111 on the linkage plate 7211 and the linkage rod 7213 on the connecting rod 7212, the connecting rod 7212 moves radially along the central cylinder 5, thereby enabling multiple inner support plates 7221 to cooperate to achieve the operation of fixing or loosening the base cylinder 1 together, ensuring the stability of the base cylinder 1 during the welding process with the heat dissipation fins 2.

[0051] The central cylinder 5 is closed at the end away from the mounting base 4. The annular connecting seat 711 includes an inner ring 7111 fitted onto and adapted to the central cylinder 5, a radial pipe 7112 communicating with the inner ring 7111, and an outer ring 7113 communicating with the radial pipe 7112. Multiple air outlet holes 7122 are provided through the inner cylinder 712 at positions corresponding to the outer ring 7113 on the side away from the mounting base 4, and multiple air return holes 7123 are provided through the inner cylinder 712 at positions corresponding to the outer ring 7113 adjacent to the mounting base 4. A heating assembly 9 is installed inside the central cylinder 5. The heating assembly 9 includes an outer pipe 91, an air outlet rotary joint 92, an inner pipe 93, and an air inlet rotary joint 94 (communicating with an external hot air system). The outer pipe 91 is provided through... The device is placed on the mounting base 4 and rotatably connected to it, with its outer wall fitting against the inner wall of the central cylinder 5; the air outlet rotary joint 92 is connected to the outer pipe 91, the inner pipe 93 passes through the air outlet rotary joint 92 and is fixed thereto, the outer wall of the inner pipe 93 is fixed to the inner wall of the outer pipe 91, and the air inlet rotary joint 94 is connected to the inner pipe 93; the central cylinder 5 is provided with an air inlet 51 and an air return outlet 52, and the outer pipe 91 is provided with an air outlet 911. The air inlet 51 corresponds to the air outlet 911 when the inner support plate 7221 is pressed against the inner wall of the base cylinder 1; the central cylinder 5 is provided with a sealing assembly 10 for sealing both ends of the base cylinder 1 when the inner support plate 7221 is pressed against the inner side of the base cylinder 1, and for opening the end of the base cylinder 1 when the inner support plate 7221 is away from the inner side of the base cylinder 1.

[0052] The closed end of the central cylinder 5 is engaged with the inner ring 7111, radial tube 7112, and outer ring 7113 of the annular connecting seat 711. Together with the inner tube 93, outer tube 91, and air inlet / outlet rotary joint 92 of the heating component 9, a stable airflow channel can be formed when the air inlet 51 and the air outlet 911 correspond. Hot air enters the inner cylinder 712 through the air outlet 911 and the air inlet 51, and then acts on the inner wall of the base cylinder 1 through the air outlet 7122. Finally, it flows back through the return air hole 7123 and the return air outlet 52, realizing the circulating heating of the inner side of the base cylinder 1. This is beneficial for preheating before welding or heat preservation after welding, improving the welding strength of the heat dissipation fins 2 and the base cylinder 1, avoiding weld cracking, and ensuring welding quality. The sealing component 10 can seal both ends of the machine base cylinder 1 during welding heating to ensure heating efficiency and temperature uniformity. When picking up or placing workpieces, the ends of the machine base cylinder 1 are left open, which does not affect the loading and unloading operations. The rotary joint does not interfere with the relative movement of the central cylinder 5 and the outer tube 91, and is adapted to the overall rotation and movement requirements of the equipment. The overall design optimizes the welding process environment, improves the processing quality, and takes into account the ease of operation, further ensuring the stability and reliability of the automated processing of the new energy vehicle motor base housing.

[0053] The sealing assembly 10 has multiple sets evenly distributed around the central cylinder 5, including a fixed plate 101, diagonal rods 102, transmission rods 103, connecting blocks 104, and sealing plates 105. The fixed plate 101 is fixed to the irregular connecting plate 713. One end of the diagonal rod 102 is hinged to the fixed plate 101. There are two diagonal rods 102 that are parallel to each other. The transmission rod 103 is fixed to one of the diagonal rods 102. The connecting rod 7212 has a through hole 72121 near its end for sliding cooperation with the transmission rod 103. The connecting block 104 is hinged to the ends of both diagonal rods 102. One side of the sealing plate 105 is fixed to the connecting block 104.

[0054] The radial movement of the connecting rod 7212 drives the transmission rod 103 to slide along the slotted hole 72121, thereby driving the inclined rod 102 to rotate around the hinge point of the fixed plate 101. The opening and closing action is achieved through the linkage of the connecting block 104 and the sealing plate 105. No additional drive structure is required, and synchronous linkage with the inner support assembly 72 is achieved. During welding heating, the sealing plate 105 can tightly seal both ends of the machine base cylinder 1 to ensure the temperature uniformity and heating efficiency of the circulating heating in the inner cylinder 712, thereby improving the welding quality. When picking up and putting down workpieces, the sealing plate 105 opens synchronously with the inner support assembly 72 without interfering with the loading and unloading operation of the machine base cylinder 1.

[0055] The mounting base 4 is provided with a rotating assembly 11 for driving the central cylinder 5 to rotate. The rotating assembly 11 includes a rotating motor 111, a driving gear 112, and a driven gear 113. The rotating motor 111 is fixed on the mounting base 4, and the output shaft of the rotating motor 111 is parallel to the central cylinder 5. The driving gear 112 is fixedly sleeved on the output shaft of the rotating motor 111, and the driven gear 113 is fixedly sleeved on the central cylinder 5 and rotatably connected to the transmission plate 84. The driven gear 113 meshes with the driving gear 112, and the thickness of the driving gear 112 is greater than the thickness of the driven gear 113.

[0056] After the rotating motor 111 starts working, it drives the driving gear 112 to rotate, thereby causing the driven gear 113 meshing with it and the central cylinder 5 fixed to the driven gear 113 to rotate. This causes the base cylinder 1, which is fixed from the inside by the fixing mechanism 7, to rotate synchronously, so that the welding robot 32 can weld the heat dissipation fins 2 to different positions on the outer circumference of the base cylinder 1.

[0057] A scissor lift 12 is fixed on the base 3. A fixed seat 121 is fixed on the top of the scissor lift 12. A roller 1211 is rotatably mounted on the fixed seat 121. A pushing robot (not shown in the figure) is provided on the side of the base 3 away from the mounting seat 4. After the machine base cylinder 1 to be processed is placed on top of the roller 1211, the operator can control the fixed seat 121 and roller 1211 to lift by using the scissor lift 12, thereby lifting the machine base cylinder 1. When the axis of the machine base cylinder 1 reaches the height of the axis of the central cylinder 5, the operator can push the machine base cylinder 1 to the outside of the inner cylinder 712 by pushing the robot, so that the machine base cylinder 1 can be fixed from the inside by the fixing mechanism 7.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
