Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, and in particular to a device and method for a double-headed upset saddle for the direction selection of the spray pipe of a new energy vehicle drive motor. Background Technology

[0002] like Figures 16 to 17 As shown, a spray pipe for a drive motor of a new energy vehicle includes a pipe fitting 11, which has a positioning hole 11b and a spray hole 11a. A saddle structure 11c is formed at both ends of the pipe fitting by a stamping process.

[0003] During the processing of this spray pipe, spray holes 11a and positioning holes 11b are first machined on the pipe fitting 11. Then, the pipe fitting 11 is placed on a stamping machine, and the two ends of the pipe fitting are stamped by the stamping machine to obtain the saddle structure 11c. However, when processing the saddle structure, there is a specific relative positional relationship between the saddle structure and the spray holes. When clamping the pipe fitting onto the stamping machine, it is necessary to rotate and adjust the pipe fitting to a specific angle position according to the position of the spray holes on the pipe fitting, and then stamp the two ends of the pipe fitting.

[0004] Traditional processing methods cannot achieve automatic positioning of the pipe fitting's angle. They often rely on manual adjustment of the angle, requiring manual rotation of the pipe fitting to a specific angle based on the position of the spray hole. This is time-consuming and labor-intensive, especially in mass production, where repeated manual adjustments can significantly slow down the processing pace. Furthermore, manual rotation of the pipe fitting may lead to deviations in the pipe fitting's angle positioning, which in turn affects the relative positional accuracy between the saddle structure and the spray hole. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art and provide a device and method for a double-headed upset saddle with a spray pipe for the drive motor of a new energy vehicle.

[0006] The objective of this invention is achieved through the following technical solution: a device for selecting the direction of the spray pipe of a new energy vehicle drive motor using a double-headed upset saddle, comprising: Control system; The hopper assembly is used to store the pipe fittings to be processed. The hopper assembly is equipped with a discharge position, from which the pipe fittings are discharged one by one. The receiving component is used to receive the pipes discharged from the hopper component and move the pipes to the detection position; A rotary orientation component is used to rotate the pipe fitting to a target angle based on the position of the spray holes on the pipe fitting. The waiting component is used to move the pipe fitting, which has been rotated to the target angle, to the waiting position; A material handling robot is used to pick up pipe fittings from the material waiting position and transport them to the stamping processing parts; Stamping components are used to stamp both ends of a pipe fitting to form a saddle structure at both ends of the pipe fitting.

[0007] Preferably, the receiving component is located below the discharge position of the hopper component; the receiving component includes a lifting seat and a lifting drive device, the lifting drive device is connected to the lifting seat and drives the lifting seat to move between the receiving position and the detection position; a pipe positioning block is provided on the lifting seat, a slope surface is provided on one side of the pipe positioning block, and a pipe positioning groove is provided at the bottom end of the slope surface; the pipes discharged from the discharge position of the hopper component fall on the slope surface of the pipe positioning block and roll down the slope surface into the pipe positioning groove.

[0008] Preferably, a plurality of guide grooves are provided at the upper end of the slope surface, and the guide grooves are arranged at equal intervals along the length direction of the pipe positioning groove. An air blowing component is slidably disposed in the guide groove, and the lower end of the air blowing component is connected to a switching cylinder. The switching cylinder drives the air blowing component to move so that the air blowing component switches between a raised state and a lowered state. An air inlet channel, a transition channel and an air outlet channel are arranged in sequence in the air blowing component. The air outlet channel is parallel to the slope surface. The transition channel is parallel to the moving direction of the air blowing component. A fixed column is fixedly disposed in the guide groove, and a plunger is disposed at the upper end of the fixed column. The plunger extends into the transition channel. One end of the air inlet channel is connected to a compressed gas device through an air pipe. When the air blowing component is in the lowered state, the upper end of the air blowing component is flush with the ramp surface, and the plunger blocks the air intake channel and the transition channel. When the air blowing component is in the raised state, the air outlet channel on the air blowing component is higher than the ramp surface, and the air intake channel and the transition channel are connected.

[0009] Preferably, the rotary orientation component includes a guide rail, on which a reference-side movable seat and a floating-side movable seat are slidably connected. The reference-side movable seat is connected to a reference-side driving component, and the floating-side movable seat is connected to a floating-side driving component. A rotating body is rotatably connected to the reference-side movable seat, and a first top material block is disposed on the rotating body. A motor for driving the rotating body to rotate is disposed on the reference-side movable seat. A second top material block corresponding to the first top material block is rotatably disposed on the floating-side movable seat. A first laser detection device is disposed on the reference-side movable seat. The material-waiting component includes a linear module, a transverse drive cylinder, a rotary drive device, a rotary arm, a material-waiting clamping device, and a second laser detection device. When rotating and orienting the pipe fitting, the first and second top blocks press the two ends of the pipe fitting together; the pipe fitting is driven to rotate around its own central axis by a motor; when the first and second laser detection devices simultaneously detect the spray holes on the pipe fitting, the angle state of the pipe fitting at this time is marked as the initial angle state; the motor continues to drive the pipe fitting to rotate by a set angle so that the pipe fitting reaches the target angle state.

[0010] Preferably, the material clamping device is provided with two openable clamps, one of which is provided with a positioning pin; the pipe is provided with a positioning hole; when the material clamping device clamps the pipe, the positioning pin on the clamp is inserted into the positioning hole on the pipe.

[0011] Preferably, the front end of the floating side drive component is provided with a floating connection mechanism, which includes a sliding shaft. The floating side moving seat is provided with a shaft hole corresponding to the sliding shaft, through which the sliding shaft passes. A first limiting end and a second limiting end are respectively provided at both ends of the sliding shaft, and a spring is provided between the first limiting end and the floating side moving seat.

[0012] Preferably, the stamping component includes a base, on which a clamping die for clamping the pipe is provided, and on both sides of the clamping die are respectively provided a die changing mechanism, on which a flaring die and a saddle forming die are provided; the base is also provided with a stamping cylinder connected to the die changing mechanism.

[0013] Preferably, the material handling robot includes a servo moving device, on which a material handling clamping component is provided, and the material handling clamping component is driven to move in the horizontal and vertical directions by the servo moving device.

[0014] A method for selecting the direction of the spray pipe of a new energy vehicle drive motor using a double-headed upset saddle, the specific method is as follows: The pipes are discharged one by one from the hopper component. The receiving component catches the discharged pipes and moves them to the detection position. When the pipe is in the detection position, the first and second top blocks on the rotating orientation component press the two ends of the pipe together, and the motor drives the pipe to rotate. During the rotation, the spray holes on the pipe are detected by the first and second laser detection devices. When the first and second laser detection devices simultaneously detect the spray holes on the pipe, the angle state of the pipe at this time is marked as the initial angle state. The motor continues to drive the pipe to rotate by the set angle so that the pipe reaches the target angle state. Subsequently, the waiting clamping device clamps the pipe, and the first and second top blocks release the pipe. The waiting clamping device is driven to rotate by the rotary drive device and transport the pipe to the waiting position. The material transfer robot grabs the pipe from the waiting position and moves it to the stamping part. The stamping part stamps both ends of the pipe to form a saddle structure.

[0015] Preferably, when the stamping component processes the pipe fitting, the pipe fitting is clamped by the clamping die. The stamping component is first switched to the flaring position. At this time, the flaring die is aligned with both ends of the pipe fitting. The flaring die is driven to move by the stamping cylinder so that the flaring die stamps both ends of the pipe fitting and forms a flared structure. Then the stamping part is switched to the saddle forming processing position. At this time, the saddle forming die is aligned with both ends of the tube. The saddle forming die is moved by the stamping cylinder so that the flaring die stamps both ends of the tube to form a saddle structure.

[0016] The beneficial effects of this invention are: 1. This invention achieves fully automated operation throughout the entire process. Through automatic material discharge from the hopper, pipe transfer via the receiving component, automatic angle positioning by the rotating orienting component, precise material loading by the transferring robot, and automatic forming of the stamping components, the entire process from pipe loading to finished product output is automated without human intervention. Compared to the traditional manual angle adjustment method, this significantly reduces the processing time per piece, making it particularly suitable for mass production scenarios and significantly increasing production capacity.

[0017] 2. The rotary orientation component can rotate the pipe to the target angle based on the position of the spray holes on the pipe, thereby ensuring that the relative positional relationship between the saddle structure and the spray holes on the pipe meets the design requirements. This ensures accurate and reliable angular positioning of the pipe. It eliminates the tedious steps of manual rotation and positioning, avoids the time wasted due to repeated manual adjustments, reduces manpower input, and improves the automation level of the production line. Furthermore, the rotary orientation component automatically identifies and rotates the pipe to the target angle based on the position of the spray holes, avoiding angular deviations caused by visual errors, fatigue, and other factors during manual operation. This ensures that the relative positional accuracy between the saddle structure and the spray holes meets the design requirements, improving product consistency. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0038] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0039] like Figures 1 to 15 As shown, a device for selecting the direction of the spray pipe of a new energy vehicle drive motor using a double-headed upset saddle includes: Control system 5; The hopper component 2 is used to store the pipe fittings 11 to be processed. The hopper component 2 is provided with a discharge position, and the pipe fittings 11 are discharged one by one from the discharge position. The receiving component 9 is used to receive the pipe fitting 11 discharged from the hopper component 2 and move the pipe fitting 11 to the detection position; The rotation orientation component 7 is used to rotate the pipe fitting 11 to a target angle state according to the position of the spray hole 11a on the pipe fitting 11. The waiting component 8 is used to move the pipe fitting 11, which has been rotated to the target angle, to the waiting position; The material handling robot 4 is used to pick up the pipe fitting 11 from the waiting position and transport the pipe fitting 11 to the stamping part 3; The stamping component 3 is used to stamp both ends of the pipe fitting 11 to form a saddle structure 11c at both ends of the pipe fitting 11.

[0040] This invention achieves fully automated operation throughout the entire process. The hopper component 2 automatically discharges material, the receiving component 9 transfers the pipe fitting 11, the rotating orientation component 7 automatically positions the angle, the material handling robot 4 precisely loads the material, and the stamping component 3 automatically forms the final product. This completes the entire process from loading the pipe fitting 11 to producing the finished product, requiring no manual intervention. Compared to the traditional manual angle adjustment method, this significantly reduces the processing time per piece, making it particularly suitable for mass production scenarios and significantly increasing production capacity.

[0041] The rotary orientation component 7 can rotate the pipe 11 to the target angle based on the position of the spray hole 11a on the pipe 11, thereby ensuring that the relative positional relationship between the saddle structure 11c and the spray hole 11a on the pipe 11 meets the design requirements, and the angular positioning of the pipe 11 is accurate and reliable. It eliminates the tedious steps of manual rotation positioning, avoids the time wasted due to repeated manual adjustments, reduces manpower input, and improves the automation level of the production line. Moreover, the rotary orientation component 7 automatically identifies and rotates the pipe 11 to the target angle based on the position of the spray hole 11a, avoiding angular deviations caused by visual errors, fatigue, and other factors during manual operation, ensuring that the relative positional accuracy between the saddle structure 11c and the spray hole 11a meets the design requirements, and improving product consistency.

[0042] The introduction of the material handling robot 4 enables the automatic transfer of the pipe fitting 11 between workstations, eliminating the hassle of manual workpiece transfer and reducing labor costs.

[0043] like Figure 4 As shown, the receiving component 9 is located below the discharge position of the hopper component 2; the receiving component 9 includes a lifting seat 9-1 and a lifting drive device 9-3. The lifting drive device 9-3 is connected to the lifting seat 9-1 and drives the lifting seat 9-1 to move between the receiving position and the detection position; a pipe positioning block 9-2 is provided on the lifting seat 9-1, and a slope surface 9-8 is provided on one side of the pipe positioning block 9-2. A pipe positioning groove is provided at the bottom end of the slope surface 9-8; the pipe 11 discharged from the discharge position of the hopper component 2 falls on the slope surface 9-8 of the pipe positioning block 9-2 and rolls down into the pipe positioning groove through the slope surface 9-8.

[0044] The receiving component 9 is mounted on a fixed base. To improve the lifting accuracy of the lifting seat 9-1, a guide rod 9-4 is provided at the bottom of the lifting seat 9-1, and a guide sleeve 9-5 corresponding to the guide rod 9-4 is provided on the fixed base. The guide rod 9-4 passes through the guide sleeve 9-5 and slides between the guide rod 9-4 and the guide sleeve 9-5. Through the cooperation between the guide rod 9-4 and the guide sleeve 9-5, the movement of the lifting seat 9-1 is well guided, effectively improving the movement accuracy of the lifting seat 9-1.

[0045] When the pipe positioning block 9-2 moves to the receiving position, the pipe 11 discharged from the hopper component 2 will fall onto the pipe positioning block 9-2. Under the guidance of the ramp surface 9-8, the pipe 11 rolls down into the pipe positioning groove at the bottom of the ramp surface 9-8. After the pipe positioning block 9-2 finishes receiving the material, the pipe positioning block 9-2 moves down to the detection position, and then the rotation orientation component 7 will perform a rotation orientation operation on the pipe 11 located at the detection position.

[0046] In this embodiment, the lifting drive device 9-3 is a cylinder.

[0047] like Figures 5 to 7As shown, a plurality of guide grooves 9-12 are provided at the upper end of the slope surface 9-8. The guide grooves 9-12 are arranged at equal intervals along the length direction of the pipe positioning groove. An air blowing component 9-15 is slidably disposed in the guide groove 9-12. The lower end of the air blowing component 9-15 is connected to a switching cylinder 9-10. The switching cylinder 9-10 drives the air blowing component 9-15 to move so that the air blowing component 9-15 switches between a raised state and a lowered state. An air inlet channel 9-16, a transition channel 9-17, and an air outlet channel 9-18 are arranged in sequence in the air blowing component 9-15. The air outlet channel 9-18 is parallel to the slope surface 9-8. The transition channel 9-17 is parallel to the movement of the air blowing component 9-15. The directions of movement are parallel; a fixed column 9-13 is fixedly installed in the guide groove 9-12, and a plunger 9-14 is installed at the upper end of the fixed column 9-13, which extends into the transition channel 9-17; one end of the air intake channel 9-16 is connected to the compressed gas device through the air pipe 9-9; when the air blowing component 9-15 is in the descending state, the upper end of the air blowing component 9-15 is flush with the slope surface 9-8, at which time the plunger 9-14 blocks the air intake channel 9-16 from the transition channel 9-17; when the air blowing component 9-15 is in the rising state, the air outlet channel 9-18 on the air blowing component 9-15 is higher than the slope surface 9-8, and the air intake channel 9-16 is connected to the transition channel 9-17.

[0048] When the pipe fitting 11 rolls from the hopper outlet onto the ramp 9-8, its rolling trajectory may become unstable due to initial speed, angle, or shift in its center of gravity, resulting in deviation, jamming, or incomplete entry into the positioning groove. This will prevent the pipe fitting 11 from reaching the detection position in the correct posture, severely affecting the subsequent rotational orientation operation of the rotating orientation component 7. In this invention, a liftable air-blowing component 9-15 is installed on the ramp 9-8 of the receiving component 9 to assist the pipe fitting 11 in accurately falling into the positioning groove using compressed gas. The specific principle is as follows: When the air blowing component 9-15 is in the descending state, its upper end is flush with the ramp surface 9-8. At this time, the plunger 9-14 blocks the air intake channel 9-16 and the transition channel 9-17, and the air outlet channel 9-18 does not release air, allowing the pipe 11 to roll off the ramp surface 9-8. After the pipe 11 rolls off the ramp surface 9-8, the air blowing component 9-15 rises and reaches the raised state. When the air blowing component 9-15 is in the raised state, the air outlet channel 9-18 on the air blowing component 9-15 is higher than the ramp surface 9-8, and the air intake channel 9-16 and the transition channel 9-17 are connected. The transition channel 9-17 is connected, and the compressed gas will pass through the inlet channel 9-16 and the transition channel 9-17 in sequence before being blown out from the outlet channel 9-18. The blown gas will be blown evenly towards the pipe 11 along the direction of the slope 9-8, so that the pipe 11 is subjected to the gas thrust in the downward direction along the slope 9-8, thereby correcting the posture of the pipe 11 and making the pipe 11 fall completely into the pipe positioning groove at the bottom of the slope 9-8 in the correct posture. The blowing component 9-15 blows for 1-1.5 seconds each time. After the blowing is completed, the blowing component 9-15 returns to the descending state.

[0049] The upper end of the telescopic rod 9-11 on the switching cylinder 9-10 is connected to the bottom of the air blowing component 9-15. The switching device drives the air blowing component 9-15 to move up and down to switch the state of the air blowing component 9-15.

[0050] To detect whether the pipe fitting 11 has accurately fallen into the pipe fitting positioning groove, a sensing component mounting hole 9-7 is provided on one side of the pipe fitting positioning groove. A sensing component 9-6 is installed in the sensing component mounting hole 9-7 to detect the presence of the pipe fitting 11. In this embodiment, the sensing component 9-6 is an infrared sensor. When the pipe fitting 11 is present in the pipe fitting positioning groove, the infrared sensor will be blocked, thereby triggering a signal to indicate that the pipe fitting 11 is present in the pipe fitting positioning groove.

[0051] like Figures 8 to 9 As shown, the rotary orientation component 7 includes a guide rail 7-1, on which a reference side moving seat 7-2 and a floating side moving seat 7-9 are slidably connected. The reference side moving seat 7-2 is connected to a reference side driving component 7-3, and the floating side moving seat 7-9 is connected to a floating side driving component 7-10. A rotating body is rotatably connected to the reference side moving seat 7-2, and a first top material block 7-7 is provided on the rotating body. A motor 7-4 for driving the rotating body to rotate is provided on the reference side moving seat 7-2. A second top material block 7-15 corresponding to the first top material block 7-7 is rotatably provided on the floating side moving seat 7-9. A first laser detection device 7-8 is provided on the reference side moving seat 7-2. like Figure 10As shown, the material receiving component 8 includes a linear module 8-1, a transverse drive cylinder 8-2 is provided on the linear module 8-1, a rotary drive device 8-3 is provided on the transverse drive cylinder 8-2, a rotary arm 8-4 is provided on the rotary drive device 8-3, a material receiving clamping device 8-5 is provided on the rotary arm 8-4, and a second laser detection device 8-9 is provided on the rotary drive device 8-3.

[0052] When rotating and orienting the pipe fitting 11, the first top material block 7-7 and the second top material block 7-15 press the two ends of the pipe fitting 11 tightly; the pipe fitting 11 is driven to rotate around its own central axis by the motor 7-4; when the first laser detection device 7-8 and the second laser detection device 8-9 simultaneously detect the spray hole 11a on the pipe fitting 11, the angle state of the pipe fitting 11 at this time is marked as the initial angle state; the motor 7-4 continues to drive the pipe fitting 11 to rotate by a set angle so that the pipe fitting 11 reaches the target angle state.

[0053] In this design, the first top material block 7-7 of the reference-side moving seat 7-2 and the second top material block 7-15 of the floating-side moving seat 7-9 form a double-end clamping structure. Through the coordinated action of the reference-side driving component 7-3 (such as a servo motor 7-4) and the floating-side driving component 7-10 (such as a cylinder), both ends of the pipe 11 are firmly fixed, preventing axial movement or circumferential slippage due to insufficient clamping force during rotation, and ensuring that the rotation center is completely aligned with the central axis of the pipe 11. The rotating body is directly driven by the motor 7-4, which rotates the first top material block 7-7. The frictional force transmitted through the double-end clamping structure drives the pipe 11 to rotate synchronously. In this embodiment, the output shaft of the motor 7-4 is connected to the rotating body via a transmission belt 7-6. The motor 7-4 is a servo motor 7-4, which has high rotational accuracy, facilitating high-precision positioning of the pipe 11.

[0054] The dual-laser detection device works together to achieve accurate initial angle calibration. The first laser detection device (installed on the reference side moving base 7-2) and the second laser detection device (installed on the rotary drive device 8-3 of the waiting component 8) simultaneously detect the position of the spray hole 11a from both ends of the pipe 11. When both lasers detect the edge of the spray hole 11a at the same time, the system determines that the pipe 11 is in the "initial angle state", which is used as the absolute reference for angle calculation, eliminating the error that may be caused by the bending of the pipe 11 or the detection blind zone due to single-end detection (the error of traditional single laser detection is about ±5°, while the error can be controlled within ±0.5° by dual laser linkage).

[0055] The system presets a target angle (e.g., the angle between the saddle structure 11c and the spray hole 11a is θ°). The motor 7-4 automatically calculates the rotation direction and number of revolutions based on the difference between the initial angle and the target angle. During rotation, the laser detection device monitors the position of the spray hole 11a in real time. If overshoot or undershoot occurs due to factors such as differences in surface reflection of the pipe 11 or rotational inertia, the system can trigger a dynamic compensation mechanism (e.g., instantaneous reverse adjustment of the motor) to ensure that the final positioning accuracy reaches ±0.1°, fully meeting the precise relative position requirements of the saddle structure 11c and the spray hole 11a.

[0056] The first laser detection device 7-8 and the second laser detection device employ a non-contact detection method. The laser beams generated by the first laser detection device 7-8 and the second laser detection device are directed at the surface of the pipe fitting 11. The first laser detection device 7-8 and the second laser detection device simultaneously receive the laser signal reflected by the pipe fitting 11. If the spray hole 11a on the pipe fitting 11 rotates to the laser irradiation position, the laser reflection signal will change. The spray hole 11a is detected based on the change in the laser reflection signal.

[0057] When the pipe fitting 11 is rotated to the target angle, the waiting clamping device 8-5 on the waiting component 8 grabs the pipe fitting 11 and moves the pipe fitting 11 to the waiting position through the rotary drive device 8-3. By transferring the position of the pipe fitting 11, the material transfer robot 4 can easily grab the pipe fitting 11 and move it to the next station.

[0058] Furthermore, the material clamping device 8-5 is equipped with two openable grippers 8-7, one of which has a positioning pin 8-8; the pipe fitting 11 has a positioning hole 11b; when the material clamping device 8-5 clamps the pipe fitting 11, the positioning pin 8-8 on the gripper 8-7 is inserted into the positioning hole 11b on the pipe fitting 11. The cooperation between the positioning pin 8-8 and the positioning hole 11b ensures the clamping accuracy of the material clamping device 8-5 on the pipe fitting 11.

[0059] A floating connection mechanism is provided at the front end of the floating side drive component 7-10. The floating connection mechanism includes a sliding shaft 7-11. A shaft hole corresponding to the sliding shaft 7-11 is provided on the floating side moving seat 7-9. The sliding shaft 7-11 passes through the shaft hole. A first limiting end 7-12 and a second limiting end 7-13 are respectively provided at both ends of the sliding shaft 7-11. A spring 7-14 is provided between the first limiting end 7-12 and the floating side moving seat 7-9. The floating connection mechanism can adapt to pipes 11 of different lengths. At the same time, the elastic buffer structure (spring) offsets the end face machining error of the pipe 11 and avoids deformation of the pipe 11 caused by rigid clamping.

[0060] like Figures 12 to 14As shown, the stamping component 3 includes a base 3-1, on which a clamping die 3-6 for clamping the pipe fitting 11 is provided. On both sides of the clamping die 3-6, a die changing mechanism 3-3 is provided. On the die changing mechanism 3-3, a flaring die 3-4 and a saddle forming die 3-5 are provided. The base 3-1 is also provided with a stamping cylinder 3-2 connected to the die changing mechanism 3-3. In this invention, during processing, the switching between the flaring die 3-4 and the saddle forming die 3-5 is achieved through the die-changing mechanism 3-3. First, the pipe fitting 11 is flared using the flaring die 3-4, and then the saddle structure 11c is formed using the saddle forming die 3-5. During the flaring process, the material at the end of the pipe fitting 11 is stretched and extended through plastic deformation, and the fiber flow becomes more uniform. When the saddle structure 11c is formed at this point, the material flows more easily according to the direction designed in the die, reducing defects such as wrinkles and cracks during forming, resulting in a clearer outline and more stable dimensions for the saddle structure 11c. If the saddle structure 11c is formed first, stress concentration already exists in local areas. The radial expansion during flaring will further exacerbate the stress in these areas, potentially causing cracking at the root of the saddle structure 11c. Flaring first allows the material to adapt to plastic deformation in advance, reducing the stress risk during subsequent forming.

[0061] like Figure 15 As shown, the material handling robot 4 includes a servo moving device 4-1, on which a material handling clamping component is provided. The material handling clamping component is driven to move in the horizontal and vertical directions by the servo moving device 4-1.

[0062] A method for selecting the direction of a double-headed upset saddle 11c for a spray pipe of a drive motor in a new energy vehicle, the specific method is as follows: Pipe fittings 11 are discharged one by one from the hopper component 2. The receiving component 9 catches the discharged pipe fittings 11 and moves them to the detection position. When the pipe fitting 11 is in the detection position, the first top material block 7-7 and the second top material block 7-15 on the rotation orientation component 7 press the two ends of the pipe fitting 11 together, and drive the pipe fitting 11 to rotate through the motor 7-4. During the rotation, the spray holes 11a on the pipe fitting 11 are detected by the first laser detection device 7-8 and the second laser detection device. When the first laser detection device and the second laser detection device simultaneously detect the spray holes 11a on the pipe fitting 11, the angle state of the pipe fitting 11 at this time is marked as the initial angle state. The motor 7-4 continues to drive the pipe fitting 11 to rotate by the set angle so that the pipe fitting 11 reaches the target angle state. Subsequently, the waiting clamping device 8-5 clamps the pipe fitting 11, and the first top material block 7-7 and the second top material block 7-15 release the pipe fitting 11; the waiting clamping device 8-5 is driven to rotate by the rotary drive device 8-3 and the pipe fitting 11 is transported to the waiting position; the material transfer robot 4 grabs the pipe fitting 11 from the waiting position and moves the pipe fitting 11 to the stamping processing component 3, and the stamping processing component 3 stamps the two ends of the pipe fitting 11 to form a saddle structure 11c at both ends of the pipe fitting 11.

[0063] When the stamping part 3 processes the pipe fitting 11, the pipe fitting 11 is clamped by the clamping die 3-6. The stamping part 3 first switches to the flaring processing position. At this time, the flaring die 3-4 is aligned with both ends of the pipe fitting 11. The flaring die 3-4 is driven to move by the stamping cylinder 3-2 so that the flaring die 3-4 stamps both ends of the pipe fitting 11 and forms a flared structure. Then the stamping part 3 is switched to the saddle forming processing position. At this time, the saddle forming die 3-5 is aligned with both ends of the tube 11. The saddle forming die 3-5 is driven to move by the stamping cylinder 3-2 so that the flaring die 3-4 stamps both ends of the tube 11 and forms the saddle structure 11c.

However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
