Description

Technical Field

[0001] This application relates to the field of motor shaft machining technology, and in particular to a knurling device for a motor shaft used in a water pump for new energy vehicles. Background Technology

[0002] With increasing attention to environmental protection and the energy crisis, new energy vehicles, as an environmentally friendly and energy-saving means of transportation, are gradually gaining popularity and favor. The electric motor is the driving source of new energy vehicles. When the electric motor rotates at high speed, it will inevitably heat up rapidly, requiring a water pump to draw coolant to cool the motor. The water pump mainly consists of components such as a motor, impeller, pump body, and seals. When the water pump is working, the motor drives the impeller to rotate at high speed, generating centrifugal force to draw out the coolant, thereby cooling the motor.

[0003] To increase the friction between the motor shaft and the outer plastic shell of the water pump motor, it is usually necessary to knurl the motor shaft at a reserved position to increase the friction between the motor shaft and the outer plastic shell, thereby increasing the torque.

[0004] Currently, because the motor shafts of water pump motors used in new energy vehicles are relatively small and long, and one end is open, manual sorting is usually used before the motor shafts are textured to ensure that they are arranged in the same direction before entering the next textured process. Although manual sorting of motor shafts is relatively simple, it requires operators to work in coordination with the speed of the textured machine to continuously sort the motor shafts, which is a lot of work and quite arduous. Summary of the Invention

[0005] In order to reduce the sorting workload of operators when performing texturing on motor shafts for water pumps in new energy vehicles, this application provides a texturing device for motor shafts for water pumps in new energy vehicles.

[0006] The texturing device for a motor shaft used in a water pump for a new energy vehicle provided in this application adopts the following technical solution:

[0007] A texturing device for a motor shaft used in a water pump for a new energy vehicle includes a frame, a vibratory feeder, a screening mechanism, and a texturing mechanism. The vibratory feeder is mounted on the frame and is used to transport the motor shaft. A ring track is formed on the inner wall of the vibratory feeder from bottom to top. The screening mechanism is mounted on the frame and is used to screen the direction of the motor shaft on the ring track. The screening mechanism includes a stop arm and a reset assembly. The stop arm is hinged to the frame, and its end faces the outlet of the ring track. The reset assembly is mounted on the frame and is used to drive the stop arm to reset. A channel is provided on the vibratory feeder, with the inlet of the channel located below the stop arm, and the channel extends to the texturing mechanism. The texturing mechanism is mounted on the frame and is used to texture the motor shaft.

[0008] By employing the above technical solution, the operator places a large number of motor shafts to be textured into a vibratory feeder. As the vibratory feeder vibrates, the motor shafts enter the ring track and gradually rise to the abutment. When the closed end of the motor shaft faces the abutment, it is squeezed out of the ring track by the pressure from the other motor shafts arranged within it, and falls back into the vibratory feeder due to gravity. When the open end of the motor shaft faces the abutment, it is then pressed onto the abutment by the subsequent motor shafts in the ring track. During this process, the abutment rotates away from the ring track as the motor shaft pushes it. When the motor shaft is completely extruded from the ring channel, the end of the motor shaft away from the abutment moves downward due to gravity, while the abutment still supports the open end of the motor shaft. At this time, the reset component drives the abutment to reset, and the abutment can push the motor shaft into the feed port of the channel below the abutment. Then the motor shaft is transported from the channel to the texturing mechanism, and the texturing mechanism textures the motor shaft. The entire process does not require manual intervention in the arrangement of the motor shaft, which can make the motor shafts arrange in the same direction in the channel to the texturing mechanism for texturing. This effectively reduces the sorting workload of operators when texturing the motor shafts of new energy vehicle water pumps.

[0009] Optionally, the reset assembly includes a first spring, a connecting line, and a counterweight. The first spring is mounted on the frame and connected to the abutment arm. The connecting line is located at the end of the abutment arm away from the ring track, and the counterweight is located on the connecting line.

[0010] By adopting the above technical solution, when the motor shaft pushes the abutment arm to rotate away from the ring track, the first spring is compressed. When the motor shaft is completely squeezed out of the ring track, the motor shaft releases its push on the abutment arm. At this time, the counterweight and the first spring work together to drive the abutment arm to rotate closer to the ring track, which can push the motor shaft into the channel and drive the abutment arm to reset. At the same time, the first spring can limit the range of rotation of the abutment arm closer to the ring track, preventing the abutment arm from rotating too much closer to the ring track, effectively improving the convenience for the operator to drive the abutment arm to reset.

[0011] Optionally, the texturing mechanism includes an abutment seat, a texturing seat, texturing rollers, a feeding assembly, and a driving component. The abutment seat is mounted on the frame and has a notch. The texturing seat is slidably mounted on the frame, and multiple texturing rollers are rotatably mounted on the texturing seat. The feeding assembly is mounted on the frame and is used to guide the motor shaft on the channel to the notch. The driving component is mounted on the frame and is used to drive the texturing seat to slide vertically on the frame.

[0012] By adopting the above technical solution, the feeding component guides the motor shaft on the channel to the notch, and then the motor shaft enters between the rubbing seat and the abutment seat from the notch. At this time, the motor shaft is clamped between the rubbing roller and the abutment seat. Then the driving component drives the rubbing seat to move downward in the vertical direction. The rubbing seat drives the rubbing roller to move downward in the vertical direction. The rubbing roller can then rub the motor shaft and drive the rubbing roller to move down to unload the material, improving the convenience for the operator to rub the motor shaft.

[0013] Optionally, the feeding assembly includes a trough, a stop block, and a control component. The trough is connected to the outlet of the channel and extends to a notch. The stop block is slidably disposed on the trough and extends into the trough. The control component is disposed on the frame and is used to control the sliding of the stop block.

[0014] By adopting the above technical solution, after the motor shaft is squeezed out of the channel outlet, it enters the material trough. When the motor shaft is conveyed in the material trough, the stop block blocks the motor shaft. When the control unit drives the stop block to slide away from the material trough, the lowest motor shaft in the material trough continues to be conveyed to the gap. Then the control unit drives the stop block to reset, blocking the subsequent motor shaft in the material trough. This allows the motor shaft in the material trough to be conveyed to the gap individually, making it convenient for the operator to drive the motor shaft for single feeding.

[0015] Optionally, the control component includes a connecting rod, a hinge rod, a cam, and a second spring. The connecting rod is hinged to the knurling seat, the hinge rod is hinged to the connecting rod, the cam is rotatably mounted on the material trough and used to abut against the motor shaft, and the cam is connected to the hinge rod. The second spring is mounted on the material trough and is connected to a stop block. The end of the stop block that abuts against the motor shaft is chamfered.

[0016] By adopting the above technical solution, the driving component drives the kneading seat to move down to knead the motor shaft. After the kneading is completed, the driving component drives the kneading seat to move up and reset. During the upward movement of the kneading seat, the connecting rod rotates, which in turn drives the hinge rod to rotate. The hinge rod then drives the cam to rotate, and the cam rotates to abut against the motor shaft. The cam pushes the motor shaft, and the motor shaft pushes the chamfered side of the stop block, causing the stop block to move up and release the obstruction of the motor shaft, completing the feeding of one motor shaft. Then, the second spring quickly drives the stop block to reset and continue to block the remaining motor shafts in the material trough. The entire process is driven by the kneading seat, without the need for additional equipment, effectively saving costs.

[0017] Optionally, the outlet of the feed trough is provided with a positioning component for positioning the motor shaft at the notch. The positioning component includes a baffle and a third spring. The baffle is hinged to the feed trough, and the third spring is disposed on the feed trough and connected to the baffle.

[0018] By adopting the above technical solution, when the motor shaft moves to the outlet of the material trough, the baffle blocks the motor shaft and positions it at the notch, preventing the motor shaft from sliding directly out of the notch from the material trough. When the rubbing seat moves down to rub the motor shaft, the rubbing roller abuts against the motor shaft at the notch, bringing the motor shaft away from the notch. During this process, the baffle rotates downward. When the motor shaft disengages from the baffle, the baffle resets under the action of the third spring, positioning the next motor shaft so that the motor shaft can stop at the notch, making it easier for the motor shaft to feed material between the rubbing roller and the abutment seat when the subsequent rubbing seat drives the rubbing roller to move down.

[0019] Optionally, a support seat is slidably disposed on the frame, the knurling seat is slidably disposed on the support seat in the direction toward the abutment seat, and a screw is rotatably disposed on the frame, the screw threaded into the support seat.

[0020] By adopting the above technical solution, the operator can rotate the screw, which will cause the support to slide on the frame. The support will then drive the knurling seat to move, thereby adjusting the distance between the knurling seat and the abutment seat, effectively improving the convenience for the operator to adjust the position of the knurling seat.

[0021] Optionally, an elastic pad is provided at one end of the abutment seat near the knurling seat.

[0022] By adopting the above technical solution, the elastic pad provides cushioning for the motor shaft, preventing the motor shaft from being damaged by pressing against the abutment seat. Furthermore, the elastic pad makes the motor shaft more stable when clamped between the abutment seat and the kneading seat, allowing the motor shaft to rotate downwards at a uniform speed with the kneading roller, thereby improving the kneading effect on the motor shaft.

[0023] Optionally, the frame is provided with a collecting mechanism for collecting the motor shaft after the texturing process is completed. The collecting mechanism includes a slide, a collecting tray and a cylinder. The slide is slidably mounted on the frame, the collecting tray is mounted on the slide, and the cylinder is mounted on the frame. The piston rod of the cylinder is connected to the slide.

[0024] By adopting the above technical solution, the operator places the collection tray on the slide. After the motor shaft is finished being rubbed, the motor shaft will fall into the collection tray under the action of gravity. At the same time, with the extension and retraction of the piston rod of the cylinder, the slide causes the collection tray to slide back and forth, so that the fallen motor shaft can be arranged more neatly in the collection tray, effectively improving the convenience for the operator to collect the rubbed motor shaft.

[0025] Optionally, the frame is provided with a guide assembly for guiding the motor shaft entering the collection tray. The guide assembly includes a guide groove and a receiving pad. The guide groove is disposed on the frame and is directly below the knurling seat. The receiving pad is disposed on the guide groove.

[0026] By adopting the above technical solution, after the motor shaft is finished with the rubbing process, it falls into the guide groove. The receiving pad provides cushioning for the motor shaft, and then the guide groove guides the motor shaft into the collection tray, improving the stability of the motor shaft when it slides into the collection tray.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The entire process does not require manual intervention in the arrangement of the motor shafts, allowing the motor shafts to be arranged in the same direction in the channel to the texturing mechanism for texturing, effectively reducing the sorting workload of operators when texturing motor shafts for new energy vehicle water pumps;

[0029] 2. When the motor shaft is conveyed in the material trough, the stop block blocks the motor shaft. When the control unit drives the stop block to slide away from the material trough, the lowest motor shaft in the material trough continues to be conveyed to the gap. Then the control unit drives the stop block to reset, blocking the subsequent motor shaft in the material trough, so that the motor shaft in the material trough can be conveyed to the gap one by one, which makes it convenient for the operator to drive the motor shaft to feed one material at a time.

[0030] 3. The slide block drives the collection tray to slide back and forth, which allows the fallen motor shafts to be arranged more neatly in the collection tray, effectively improving the convenience for operators to collect the motor shafts after the texturing is completed.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses a texturing device for the motor shaft of a water pump used in new energy vehicles.

[0039] Reference Figure 1 The texturing device for the motor shaft of a water pump for new energy vehicles includes a frame 1, a vibrating plate 2, a screening mechanism 3, and a texturing mechanism 4.

[0040] Reference Figure 1 , Figure 2 The vibratory feeder 2 is mounted on the frame 1. The vibratory feeder 2 is used to convey the motor shaft. In this embodiment, the vibratory feeder 2 is composed of components such as a hopper, a motor, and a controller. By driving the hopper to vibrate, the motor shaft in the hopper is driven to vibrate, thereby adjusting the position of the motor shaft in the hopper. A ring track 5 is installed on the inner side wall of the vibratory feeder 2. The ring track 5 is arranged in a ring from bottom to top on the inner side wall of the vibratory feeder 2. The diameter of the ring track 5 gradually decreases from bottom to top, making it easy for the motor shaft to be fed from the vibratory feeder 2 into the ring track 5, and arranged one by one in the ring track 5.

[0041] Reference Figure 2 , Figure 3 The screening mechanism 3 is installed on the frame 1. The screening mechanism 3 is used to screen the direction of the motor shaft on the ring track 5. In this embodiment, a partition is installed at the discharge end of the ring track 5. The partition divides the ring track 5 into two conveying channels. Two screening mechanisms 3 are installed on the frame 1. The two screening mechanisms 3 correspond to one conveying channel respectively. When the conveying channel on one ring track 5 is blocked, the operator can feed the motor shaft through the other conveying channel, which prevents the need to stop the machine to clear the blockage when the ring track 5 is blocked, thereby improving production efficiency.

[0042] The screening mechanism 3 includes a stop arm 31 and a reset assembly 32. The stop arm 31 is hinged to the frame 1. In this embodiment, the end of the stop arm 31 near the ring track 5 protrudes towards the ring track 5, and the diameter of the protruding end is smaller than the inner diameter of the open end of the motor shaft. A guide plate 13 is installed on the frame 1, and a guide strip hole is provided on the guide plate 13. The width of the guide strip hole is the same as the diameter of the stop arm 31. The stop arm 31 slides in the guide strip hole, increasing the stability of the stop arm 31 when rotating. The reset assembly 32 is installed on the frame 1 and is used to drive the stop arm 31 to reset. The reset assembly 32 includes a first spring 321, a connecting wire 322, and a counterweight 323. One end of the first spring 321 is installed on the guide plate 13, and the other end is installed on the stop arm 31. When the first spring 321 is in its original state... At this time, the protruding end of the abutment arm 31 is directly opposite the ring track 5. The connecting line 322 is installed at the end of the abutment arm 31 away from the ring track 5. The connecting line 322 can be a steel rope, nylon rope, etc. In this embodiment, the connecting line 322 is a nylon rope. The counterweight 323 is installed at the end of the connecting line 322 away from the abutment arm 31. In this embodiment, the counterweight 323 is two nuts, and the connecting line 322 is wound around the two nuts. A channel 6 is installed on the vibrating plate 2. The channel 6 is used to guide and transport the motor shaft to the texturing mechanism 4 for feeding. The feed port of the channel 6 is located below the abutment arm 31, and the channel 6 is wound around the outer wall of the vibrating plate 2, so that the vibrating plate 2 can drive the channel 6 to vibrate when it vibrates. The channel 6 extends to the texturing mechanism 4. The texturing mechanism 4 is installed on the frame 1 and is used to texture the motor shaft.

[0043] The operator places a large number of motor shafts to be textured into the vibratory feeder 2, then starts the vibratory feeder 2. The vibratory feeder 2 drives the internal motor shafts to vibrate, causing the motor shafts inside the vibratory feeder 2 to enter the ring track 5. Then, as the ring track 5 gradually rises, when the motor shaft is conveyed from the ring track 5 to the abutment arm 31, if the closed end of the motor shaft on the ring track 5 faces the abutment arm 31, with the subsequent compression of the motor shafts in the ring track 5, the motor shaft is squeezed out of the ring track 5. Under the action of gravity, the motor shaft falls directly into the vibratory feeder 2 and continues to be vibrated. The material is fed into the annular channel 5; if the open end of the motor shaft faces the abutment arm 31, with the subsequent compression of the motor shaft within the annular channel 5, the motor shaft with this open end facing the abutment arm 31 will move towards the abutment arm 31, and then the protruding end of the abutment arm 31 will insert into the open end of the motor shaft. The motor shaft will then be gradually squeezed out of the annular channel 5. During this process, the motor shaft compresses the abutment arm 31, causing the abutment arm 31 to rotate. During this rotation, the abutment arm 31 drives the first spring 321 to compress, and then the end of the motor shaft away from the abutment arm 31 is... Under the influence of gravity, the motor shaft moves downwards, while the protruding end of the abutment arm 31 continues to support the motor shaft. Then, the first spring 321 and the counterweight 323 work together to drive the abutment arm 31 to reverse and reset. During the reversal and reset process of the abutment arm 31, the motor shaft can be pushed into the channel 6. Then, the motor shaft is transported from the channel 6 to the texturing mechanism 4 for texturing. The entire motor shaft loading and sorting process does not require manual intervention, and the motor shafts can be arranged in the same direction and transported to the texturing mechanism 4, effectively reducing the sorting workload of the operator when texturing the motor shaft of the new energy vehicle water pump. In addition, during the reset process of the abutment arm 31, the first spring 321 limits the range of rotation of the abutment arm 31 towards the ring track 5, preventing the abutment arm 31 from rotating too much towards the ring track 5. Under the action of the first spring 321 and the counterweight 323, the abutment arm 31 can be kept in a state where the protruding end of the abutment arm 31 is aligned with the ring track 5, effectively improving the convenience for the operator to drive the abutment arm 31 to reset accurately.

[0044] Reference Figure 4 , Figure 5The texturing mechanism 4 includes an abutment seat 41, a texturing seat 42, a texturing roller 43, a feeding assembly 44, and a driving component 45. The abutment seat 41 is mounted on the frame 1, and a notch 411 is provided on the abutment seat 41 for the motor shaft to slide into. A support seat 8 is slidably mounted on the frame 1 toward the abutment seat 41. In this embodiment, a guide rail is mounted on the frame 1, and the support seat 8 slides on the guide rail to improve the stability of the support seat 8 when sliding. A screw 9 is rotatably mounted on the frame 1. In this embodiment, multiple screws 9 are rotatably mounted on the frame 1, and multiple screws 9 are threaded through the support seat 8. The support seat 8 has a vertical opening. The device has a dovetail groove, and the texturing seat 42 is slidably installed in the dovetail groove. The texturing seat 42 is directly opposite the abutment seat 41. Multiple texturing rollers 43 are rotatably installed on the texturing seat 42. The outer wall of the texturing rollers 43 is textured. When the operator rotates the screw 9, the screw 9 can make the support seat 8 slide closer to or away from the abutment seat 41, thereby making the texturing seat 42 slide closer to or away from the abutment seat 41. This allows the operator to adjust the distance between the texturing seat 42 and the abutment seat 41, thereby adjusting the distance between the texturing rollers 43 and the abutment seat 41. This also allows the operator to control the depth of texturing on the motor shaft.

[0045] The feeding assembly 44 is mounted on the frame 1. The feeding assembly 44 is used to guide the motor shaft on the channel 6 to the notch 411. The feeding assembly 44 includes a feed trough 441, a stop block 442, and a control component 443. The feed trough 441 is mounted on the frame 1. The feed end of the feed trough 441 is connected to the channel 6, and the discharge end of the feed trough 441 is connected to the notch 411. In this embodiment, a feed hole is provided on the side wall of the feed trough 441, which is directly opposite to the channel 6. The width of the feed trough 441 gradually decreases from the end near the channel 6 to the end away from the channel 6, so that the motor shaft can easily slide downward in the feed trough 441 and then be arranged horizontally in the feed trough 441. The stop block 442 is slidably mounted on the feed trough 441 and extends into the feed trough 441. The end of the stop block 442 located in the feed trough 441 and facing away from the notch 411 is... Chamfer setting; control component 443 is mounted on frame 1. Control component 443 is used to drive stop 442 to slide when the knurling seat 42 moves. Control component 443 includes connecting rod 4431, hinge rod 4432, cam 4433 and second spring 4434. Connecting rod 4431 is hinged to knurling seat 42. Hinged rod 4432 is hinged to the end of connecting rod 4431 away from knurling seat 42. Cam 4433 is rotatably mounted on material trough 441. Cam 4433 is used to abut against a motor shaft at the lower end of material trough 441. Cam 4433 is connected to the end of hinge rod 4432 away from connecting rod 4431. One end of second spring 4434 is mounted on material trough 441 and the other end is mounted on stop 442. Second spring 4434 always has the tendency to drive stop 442 to slide closer to material trough 441.

[0046] The drive component 45 is mounted on the frame 1. The drive component 45 is used to drive the knurling seat 42 to move vertically on the frame 1. In this embodiment, the drive component 45 is a cylinder, which is vertically mounted on the frame 1. The piston rod of the cylinder is connected to the knurling seat 42. In other embodiments, the drive component 45 can also be an electric actuator, etc.

[0047] When the motor shaft on channel 6 is conveyed to the material trough 441, it is squeezed into the feed hole on the material trough 441 by the subsequent motor shaft on channel 6, and then enters the material trough 441. It moves downwards within the material trough 441, and the stop block 442 blocks the lowest motor shaft in the material trough 441, causing the motor shafts to be arranged within the material trough 441. When the drive unit 45 drives the knurling seat 42 to move vertically upwards on the frame 1, since the lengths of the connecting rod 4431 and the hinge rod 4432 are constant, the knurling seat 42 moves... The distance between the hinge point of the connecting rod 4431 on the knurling seat 42 and the connection point of the hinge rod 4432 on the cam 4433 changes. Therefore, the knurling seat 42 can drive the connecting rod 4431 to rotate, which in turn drives the hinge rod 4432 to rotate. The hinge rod 4432 then drives the cam 4433 to rotate, causing the protruding end of the cam 4433 to rotate and protrude from the material groove 441. The cam 4433 abuts against a motor shaft at the lowest end of the material groove 441, causing this motor shaft to press against the stop. The chamfered surface of block 442 causes the stop block 442 to move upward, allowing the motor shaft to pass through the block block 442 and slide to the notch 411 for feeding. After the stop block 442 is pushed upward by the motor shaft, the second spring 4434 quickly drives the stop block 442 to move downward and reset, continuing to block the subsequent motor shaft in the material trough 441. Then the motor shaft slides from the notch 411 between the abutment seat 41 and the knurling seat 42. The drive component 45 then drives the knurling seat 42 downward, and during the downward movement of the knurling seat 42, it drives the connecting rod. 4431, hinge rod 4432 and cam 4433 are reset and drive multiple texturing rollers 43 to move down. Multiple texturing rollers 43 and abutment seat 41 clamp the motor shaft, and the texturing rollers 43 can perform texturing on the motor shaft. The texturing rollers 43 are driven to move down to unload the material, which improves the convenience for the operator to perform texturing on the motor shaft. In addition, the up and down reciprocating motion of the texturing seat 42 controls the motor shaft in the material trough 441 to perform single feeding without the need for additional equipment to drive it, and it is convenient for the operator to drive the motor shaft to perform single feeding.

[0048] Reference Figure 4 , Figure 5 In this embodiment, a limiting groove 412 is provided at one end of the abutment seat 41 near the knurling seat 42. The limiting groove 412 is connected to the notch 411. The opening width of the limiting groove 412 is the same as the width of the motor shaft, and the opening depth of the limiting groove 412 is less than the diameter of the motor shaft. An elastic pad 10 is installed on the bottom wall of the limiting groove 412. The elastic pad 10 can be made of rubber, silicone, sponge, or other materials. In this embodiment, the elastic pad 10 is made of rubber.

[0049] As the motor shaft enters the limiting groove 412 through the notch 411, the motor shaft rolls within the limiting groove 412 during the downward movement of the texturing seat 42. The limiting groove 412 guides the rolling of the motor shaft, improving the stability of the downward movement of the motor shaft. During the texturing process, the motor shaft comes into contact with the elastic pad 10, which provides cushioning to prevent the motor shaft from being damaged by pressing against the abutment seat 41. The elastic pad 10 also increases the friction between the motor shaft and the abutment seat 41, making the motor shaft more stable when clamped between the abutment seat 41 and the texturing seat 42. This allows the motor shaft to rotate at a uniform speed as the texturing roller 43 moves downward, improving the texturing effect on the motor shaft.

[0050] Reference Figure 4 , Figure 5 A positioning component 7 is installed at the outlet of the feed trough 441. The positioning component 7 is used to position the motor shaft at the notch 411. The positioning component 7 includes a baffle 71 and a third spring 72. In this embodiment, a mounting groove is provided at the bottom of the feed trough 441. The opening width of the mounting groove is smaller than the length of the motor shaft. The baffle 71 is hinged to the inner wall of the mounting groove. The baffle 71 is arc-shaped. One end of the third spring 72 is installed on the side wall of the mounting groove and the other end is installed on the baffle 71. The third spring 72 always has the tendency to drive the baffle 71 to rotate closer to the notch 411.

[0051] When the motor shaft rolls from the material trough 441 to the notch 411, the baffle 71 blocks the motor shaft, positioning it at the notch 411 and ensuring that part of the motor shaft is outside the notch 411, preventing the motor shaft from sliding directly away from the notch 411. When the knurling seat 42 moves down, the knurling roller 43 abuts against the motor shaft again, and the motor shaft presses against the baffle 71, causing the baffle 71 to rotate away from the notch 411, allowing the motor shaft to enter the limiting groove 412. After the motor shaft disengages from the baffle 71, the third spring 72 drives the baffle 71 to rotate closer to the notch 411, blocking and positioning the next motor shaft again. This ensures that when the motor shaft enters the notch 411 from the material trough 441, it can stop at the notch 411, thus ensuring that when the knurling seat 42 drives the knurling roller 43 to move down, the motor shaft can be accurately fed between the knurling roller 43 and the abutment seat 41, effectively providing accuracy in feeding the motor shaft between the knurling roller 43 and the abutment seat 41.

[0052] Reference Figure 1 , Figure 4A collection mechanism 11 is installed on the frame 1. The collection mechanism 11 is used to collect the motor shaft after the texturing process. The collection mechanism 11 includes a slide block 111, a collection tray 112, and a collection cylinder 113. The slide block 111 is slidably installed on the frame 1. In this embodiment, a slide rail is installed on the frame 1, and the slide block 111 slides on the slide rail to improve the stability of the slide block 111 when sliding. A positioning groove is opened on the slide block 111 for the collection tray 112 to be placed in. The collection tray 112 is placed in the positioning groove on the slide block 111, and the collection cylinder 113 is installed on the frame 1. Above, the piston rod of the collecting cylinder 113 is connected to the slide block 111; a guide assembly 12 is also installed on the frame 1. The guide assembly 12 is used to guide the motor shaft entering the collecting tray 112. The guide assembly 12 includes a guide groove 121 and a receiving pad 122. The guide groove 121 is installed on the frame 1 and is arc-shaped. The guide groove 121 is connected to the limiting groove 412 and faces the collecting tray 112. The receiving pad 122 is installed on the inner wall of the guide groove 121. In this embodiment, the receiving pad 122 is a sponge pad.

[0053] After the motor shaft is textured by the texturing roller 43, it falls onto the receiving pad 122 under gravity. The receiving pad 122 provides cushioning for the motor shaft, preventing it from impacting the guide groove 121. Then, the motor shaft moves down into the collection tray 112 for collection along the guide groove 121. With the extension and retraction of the collection cylinder 113, the slide 111 is driven to slide back and forth on the frame 1. The slide 111 drives the collection tray 112 to move back and forth, so that the motor shafts falling from the guide groove 121 into the collection tray 112 can be arranged neatly in the collection tray 112, effectively improving the convenience for the operator to collect the textured motor shafts. After a collection tray 112 is full of motor shafts, the operator can directly remove the collection tray 112 from the slide 111 and put it into another collection tray 112 to collect subsequent motor shafts.

[0054] The implementation principle of the texturing device for a motor shaft used in a water pump of a new energy vehicle in this application embodiment is as follows: The operator pours multiple motor shafts into the vibratory plate 2 and starts the vibratory plate 2. The motor shafts can then gradually rise along the ring track 5 to the abutment arm 31. If the closed end of the motor shaft faces the abutment arm 31, the motor shaft falls into the vibratory plate 2. If the open end of the motor shaft faces the abutment arm 31, the open end of the motor shaft fits into the protruding end of the abutment arm 31. During the process of the motor shaft being completely squeezed out of the ring track 5, the motor shaft drives the abutment arm 31 to rotate away from the ring track 5. Then, the counterweight 323 and the spring drive the abutment arm 31 to reset. During the reset process, the abutment arm 31 supports the motor shaft and pushes the motor shaft into the channel 6. Then, the motor shaft is transported from the channel 6 to the material trough 441 for arrangement. When the driving component 45 drives the texturing seat 42 to move upward, the texturing seat 42 controls the cam 4433 to abut against the lowest motor shaft in the material trough 441 through the connecting rod 4431 and the hinge rod 4432. The motor shaft pushes aside the stop 442 and is then conveyed to the notch 411. The baffle 71 positions the motor shaft, and the drive unit 45 drives the texturing seat 42 to move downward. The texturing roller 43 then pushes the motor shaft into the limiting groove 412. The buffer pad on the bottom wall of the limiting groove 412 provides cushioning for the motor shaft and increases the friction between the motor shaft and the bottom wall of the limiting groove 412. As the texturing seat 42 continues to move downward, the texturing roller 43 drives the motor shaft to rotate downward, and the texturing roller 43 presses against the motor shaft, thus texturing the outer surface of the motor shaft. After texturing, the motor shaft is guided by the guide groove 121 and falls neatly into the collection tray 112 for collection. The entire process does not require manual intervention in the arrangement of the motor shafts, allowing the motor shafts to be arranged in the same direction in the channel 6 to the texturing mechanism 4 for texturing. This effectively reduces the sorting workload of the operator when texturing the motor shafts of the new energy vehicle water pump and improves the texturing effect of the motor shafts.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
