Description

Technical Field

[0001] This invention relates to the field of motor housing processing technology, specifically to a processing device and method for aluminum alloy motor housing profiles for new energy vehicles. Background Technology

[0002] As a core component of the power system, the machining precision and surface cleanliness of the motor housing in new energy vehicles directly affect the motor's electromagnetic performance and heat dissipation efficiency. After CNC machining, the complex internal structure of the motor housing (such as water-cooled sleeve channels, high-precision stator mounting slots, and deep blind holes) will retain a large amount of metal cutting fluid, aluminum powder, and other industrial contaminants. If these residues are not completely removed, they can not only cause sealing failures during motor assembly but also lead to serious malfunctions due to short circuits caused by residual debris during high-speed motor operation.

[0003] Currently, the industrial sector primarily uses mesh belt ultrasonic cleaning machines for assembly line cleaning of motor housings. A typical cleaning process involves placing the motor housing on a continuously rotating metal mesh belt, where the cleaning solution in the cleaning tank, combined with ultrasonic cavitation, removes the dirt. Existing equipment mostly employs horizontal conveying (i.e., the motor housing's axis is parallel to the conveyor belt surface) or vertical conveying (i.e., the end face of the motor housing rests against the conveyor belt surface). However, in practical use, the following problems still exist: When conveying in a horizontal position, the complex cavity inside the motor housing is prone to forming air pockets (air resistance effect) in the depths due to the surface tension of the cleaning fluid, which hinders the ultrasonic cavitation bubbles from contacting the dirt inside the hole, making it difficult to clean blind holes and the inner walls of cooling water channels. When using a vertical conveyor, although there are fewer air resistance issues (because air can be discharged from above), a "shadow zone" is formed at the bottom contact surface with the mesh belt. This results in areas such as grooves and threaded holes on the bottom end face not being effectively covered by acoustic energy, leading to problems such as incomplete cleaning and inconvenience in cleaning. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a processing device and method for aluminum alloy motor housing profiles for new energy vehicles, which can clean the grooves, threaded holes, and other areas between the end faces of the motor housing profile.

[0011] Furthermore, the drive mechanism includes a reversing assembly, a reset assembly, a transmission assembly, a force-receiving assembly, and several thrust assemblies. One end of the reset assembly is connected to the outer wall of the second housing, and the other end of the reset assembly is connected to one end of the transmission assembly. The other end of the transmission assembly extends into the interior of the second housing and is connected to both the reversing assembly and the force-receiving assembly. The other end of the force-receiving assembly is connected to the second housing, and the other end of the reversing assembly is connected to the valve stem of the valve. One end of each of the several thrust assemblies is connected to one end of a several V-shaped plates, and the other ends of the several thrust assemblies are aligned with the position of the force-receiving assembly.

[0012] Furthermore, the thrust assembly includes a second rod and a full gear, one end of the second rod is fixedly connected to one end of the V-shaped plate, and the other end of the second rod is fixedly connected to the shaft of the full gear; The reset assembly includes a second block, a spring, a rack plate, and a spur gear. One side of the second block is fixedly connected to the outer wall of the second housing, and the other side of the second block is fixedly connected to one end of the spring.

The half gear matches the full gear and meshes with the contacting full gear. The outer wall of the fourth rod is fixedly connected to the shaft of the second sprocket.

[0013] Furthermore, two third housings are fixedly connected to the surface of the limiting track near the drive mechanism. Each of the two third housings has a first groove through it on the side near the conveyor belt. The height of the first groove is not less than the diameter of the second rod. The size of the inner wall of the third housing is not less than the diameter of the full gear. The full gear is located inside the third housing. The two third housings are located on both sides of the second housing.

[0014] Furthermore, a processing method for a new energy vehicle aluminum alloy motor housing profile processing device includes the following steps: Step 1: Adjust and lock the position of the positioning component on the V-shaped plate according to the hole position of the motor housing profile, insert the profile into the first rod body for fixation, so that the profile maintains a specific posture when moving with the conveyor belt; Step 2: The conveyor belt moves the profile to the descending section of the wavy area, so that the profile is completely immersed in the cleaning fluid in the first housing. At the same time, the profile is initially ultrasonically cleaned using ultrasonic equipment. Step 3: The conveyor belt continues to move the profile to the rising section of the wavy area. At this time, the thrust component moves and impacts and pushes the force-bearing component, opening the valve through the mechanical linkage of the transmission component and the reversing component. Afterwards, the external water supply equipment draws cleaning fluid through the three-way valve and the second pipe, and then uses the water spray assembly to rinse the profile end face which is in an uphill inclined state, and removes air bubbles and impurities from the hole. Step 4: The profile continues to move forward, the thrust component disengages from the force-bearing component, and the reset component, under the action of the spring, drives each component back to its position and closes the valve, stopping the flushing. Subsequently, the profile enters the next wavy area with the conveyor belt and is immersed in the cleaning solution again for cleaning. Step 5: When the profile leaves the cleaning area, the accumulated liquid is drained by tilting it. Then it passes through the draining area and the drying area in sequence. Finally, the staff removes the profile from the limiting mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This new energy vehicle aluminum alloy motor housing profile processing device and processing method, by setting up a wavy conveyor belt and limiting track, in conjunction with a flushing mechanism, flushes the end face of the motor housing profile when it is tilted uphill, eliminating the air resistance effect in the deep cavity blind hole, allowing the cleaning fluid to enter the hole and wash away the residual cutting fluid and aluminum powder. Furthermore, when the profile leaves the cleaning area, the internal water can automatically flow out by the tilt angle, improving the thoroughness of cleaning.

[0016] This new energy vehicle aluminum alloy motor housing profile processing device and its processing method, by setting up a set of purely mechanically linked thrust components, reversing components, transmission components and force-bearing components, once the profile leaves, the spring of the reset component will pull each component back to its position and automatically shut off the water. The whole process is purely mechanically linked, without the need to add an additional electronic control sensor. It not only achieves precise "water flushing when the object comes and water stopping when the object leaves" to save water resources, but also eliminates the hidden danger of electronic control components malfunctioning and short-circuiting in humid environments.

[0017] This new energy vehicle aluminum alloy motor housing profile processing device and its processing method replace the traditional high-pressure water gun's single-point direct water line by setting up a water spray assembly with arrayed or fan-shaped nozzles. During rinsing, it is not necessary to precisely aim the water flow at a specific groove or deep hole of the profile; it can directly cover and rinse a large area, which has a very high fault tolerance rate. It not only completely eliminates cleaning dead corners, but also easily accommodates motor housing profiles of various sizes and hole distributions produced on mixed production lines, thus improving the equipment's versatility.

[0018] This new energy vehicle aluminum alloy motor housing profile processing device and processing method, by setting a limiting mechanism with a V-shaped plate and positioning components, can not only firmly clamp the motor housing profile on the conveyor belt to prevent it from rolling off when it moves with waves or is impacted by water curtain, but also adjust the position of the first rod in the second groove to adapt to the hole position of various profile types and lock and shape it.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Please see Figures 1-11 A new energy vehicle aluminum alloy motor housing profile processing device includes a cleaning body 1, which includes a first housing 11 for holding cleaning fluid, a second housing 12 for separating a cleaning area, a draining area and a drying area, several maintenance doors 13 for maintenance, a conveyor belt 14 for conveying the motor housing profile, and two limiting tracks 15 that restrict the movement of the conveyor belt 14 and are located on both sides of the conveyor belt 14 and fixed on the first housing 11. Several ultrasonic transducer arrays are installed at the bottom of the inner wall of the first housing 11. The ultrasonic transducers are electrically connected to an external ultrasonic generator. The conveyor belt 14 is driven by a drive motor located at the end of the first housing 11 to rotate in a cycle. The portion of the conveyor belt 14 and the two limiting tracks 15 located in the cleaning zone has a wavy, undulating shape, forming a wavy, undulating area; the processing device also includes: Several limiting mechanisms 2 are provided on the conveyor belt 14 to limit the position of the motor housing profile when it moves synchronously with the conveyor belt 14. The rinsing mechanism 5 is located in the undulating area of ​​the wavy line and can rinse the holes and grooves on the end face of the motor housing profile when the motor housing profile moves to the undulating area of ​​the wavy line. The water supply mechanism 6 is connected to the first housing 11 and the rinsing mechanism 5 respectively. It can drive the cleaning fluid to circulate between the first housing 11 and the rinsing mechanism 5 during operation and discharge the cleaning wastewater after cleaning is completed. The drive mechanism 4 is connected to the flushing mechanism 5 and cooperates with the limiting mechanism 2. It can open the flushing mechanism 5 when the conveyor belt 14 carries the motor housing profile to the front section of the wavy line undulation area, and close the flushing mechanism 5 when the conveyor belt 14 carries the motor housing profile to the rear section of the wavy line undulation area.

[0023] It should be noted that the aforementioned basic components, such as the first housing 11, the second housing 12, the inspection door 13, the conveyor belt 14, the limiting track 15, the ultrasonic transducer array, the external ultrasonic generator, and the drive motor, are all common commercially available products or mature existing technologies in this field. The core innovation of this invention lies in the improvement of the conveying trajectory and the addition of a mechanically linked flushing structure. Therefore, to keep the description concise and to the point, this embodiment will not elaborate on the internal structure, working principle, and basic wiring methods of the aforementioned conventional components. Those skilled in the art can fully realize its basic operating functions using existing technology and common sense.

[0024] Furthermore, in order to prevent the motor housing profile to be cleaned from loosening when it moves with the undulating lines of the conveyor belt 14, and also to facilitate the rinsing mechanism 5 to more accurately flush the rinsing liquid into the threaded hole or groove, as a preferred embodiment of the present invention, the limiting mechanism 2 includes a first plate 21, a V-shaped plate 22 and at least one positioning component 23. Both ends of the first plate 21 are fastened to the conveyor belt 14 by first bolts, and the middle part of the first plate 21 is fixedly connected to the middle part of the V-shaped plate 22. The surfaces of both ends of the V-shaped plate 22 are provided with second grooves 222. The positioning component 23 is located in one of the second grooves 222. One end of the V-shaped plate 22 is also connected to the drive mechanism 4. Specifically, by setting the limiting mechanism 2, the motor housing profile that moves together with the conveyor belt 14 can be firmly locked, preventing them from shaking and deviating when they move with the undulating wave line or are impacted by the water flow. In this way, in the subsequent rinsing stage, the sprayed water can be more accurately hit into the holes on the end face of the motor housing.

[0025] Furthermore, in order to ensure the position of the motor housing profile and to be able to adapt to more motor housing profiles of different sizes, as a preferred embodiment of the present invention, the positioning component 23 includes a first rod 231, a first block 232 and a nut 233. The outer wall of the middle part of the first rod 231 is fixedly connected to the inner wall of the first block 232, the outer wall of the first block 232 is slidably connected to the inner wall of the second groove 222, one end of the first rod 231 passes through the second groove 222 and is threadedly connected to the nut 233, one side of the nut 233 abuts against the surface of the V-shaped plate 22, and the nut 233 is located on the outside of the V-shaped plate 22. Specifically, by setting up the positioning component 23, the staff can flexibly adjust the position of the first rod 231 in the second groove 222 according to the hole positions on the motor housing profiles of different models and sizes. After the position is found, the nut 233 and the first block 232 are clamped and fixed, which can easily adapt to various motor housings and make the equipment more versatile.

[0026] Furthermore, since the motor housing profile has a certain weight, in order to improve the service life of the V-shaped plate 22, as a preferred embodiment of the present invention, the surfaces of both ends of the first plate 21 are fixedly connected to the second plate 221, and the other ends of the two second plates 221 are respectively fixedly connected to the two ends of the V-shaped plate 22. Specifically, by setting the second plate 221, an additional layer of force support is added to both ends of the V-shaped plate 22. Since the aluminum alloy motor housing profile itself has a certain weight, the addition of the second plate 221 to share the weight can effectively prevent the V-shaped plate 22 from bending and deforming due to long-term load, making the limiting mechanism 2 last longer and be more reliable.

[0027] Furthermore, in order to flush the threaded holes or grooves on the end face of the motor housing profile, as a preferred embodiment of the present invention, the flushing mechanism 5 includes a third plate 51 and a water spray assembly 52. ​​The axial direction of the third plate 51 is parallel to the width direction of the conveyor belt 14. The two ends of the third plate 51 are respectively connected to the second housing 12 and one of the inspection doors 13. The side of the third plate 51 located inside the second housing 12 is connected to one end of the water spray assembly 52, and the other end of the water spray assembly 52 faces the wavy area of ​​the conveyor belt 14. Specifically, by setting up a rinsing mechanism 5, the motor housing profile is aligned with the wavy, uphill area of ​​the conveyor belt 14. While the profile is tilted and less prone to air resistance, the grooves or threaded holes on the end face are directly rinsed with water to thoroughly flush out the cutting fluid and aluminum dust hidden inside.

[0028] Furthermore, in order to more accurately spray the flushing liquid onto the threaded holes or grooves on the end face of the motor housing profile, as a preferred embodiment of the present invention, the water spray assembly 52 includes a spray pipe 521 and a first pipe body 522. One end of the first pipe body 522 is located outside the second housing 12 and is fixedly connected to the output end of the external water supply equipment. The other end of the first pipe body 522 penetrates into the interior of the second housing 12 and is fixedly connected to one side of the spray pipe 521. Several nozzles of the spray pipe 521 are all facing the undulating area of ​​the wavy line of the conveyor belt 14. A valve 523 with a valve stem is provided inside the first pipe body 522. It should be noted that valve 523 can be a ball valve, which is commonly available on the market. The shaft of the first bevel gear 421 is fixedly connected to the top of the valve stem of the ball valve, while the bottom of the valve stem is located in the inner cavity of the first tube 522 and is coaxially linked with the built-in ball valve core. A full-bore guide hole is transversely opened on the geometric center axis of the valve core. The inner diameter of this guide hole is consistent with the cross-sectional area of ​​the flow channel of the first tube 522. This can eliminate the head loss caused by the shrinkage of the pipe diameter by ensuring the instantaneous dynamic pressure of the water curtain jet when the fluid is connected.

[0029] Furthermore, since the meshing stroke of the full gear 412 and the half gear 451 is limited by the moving window of the profile, the maximum rotational stroke of the reversing component 42 given by the transmission component 44 is also limited. Therefore, through the vertical orthogonal transmission of the first bevel gear 421 and the second bevel gear 422, the maximum working angular displacement of the valve stem is strictly limited to 90 degrees (i.e., a quarter circumference).

[0030] This causes the valve stem to be forced to rotate 90° clockwise (or counterclockwise) when the linear thrust of the thrust assembly 41 is completely converted into the rotational torque of the reversing assembly 42. At this time, the axis of the guide hole inside the valve core coincides with the water flow direction of the first pipe 522, and the system achieves an absolute physical connection. The pressurized cleaning fluid can penetrate the valve core instantly and pour out through the nozzle 521 to the inclined profile end face.

[0031] Once the profile leaves the contact area, the thrust decreases to zero, and the potential energy of the spring 432 stored in the reset component 43 is released instantly. The thrust of the spring 432 will cause the entire mechanical transmission link to reverse, and the valve stem will rotate 90° in the opposite direction to reset. At this time, the axis of the guide hole is perpendicular to the diameter of the first pipe body 522, and the water path is tightly locked by the non-porous solid wall of the valve core, thus achieving a clean and efficient physical interception without any electromagnetic induction.

[0032] Specifically, by setting up the water spray assembly 52, the first pipe 522 carries the cleaning fluid into the interior, and then sprays out a "wide sheet" of water through a row of downward-sloping nozzles (which can be fan-shaped nozzles or densely arranged straight nozzles) on the spray pipe 521. This design does not spray out a single "water line" like a traditional high-pressure water gun, but a large water curtain that can cover the entire end face of the motor housing. Its advantage is that during rinsing, there is no need to precisely aim the water flow at a specific groove or deep hole. It can directly "cover" the surface for rinsing. Regardless of the distribution of the holes or the use of different models and sizes of motor housings, it can achieve coverage without dead angles. At the same time, the water flow can be cut off in time when rinsing is not needed through the internal valve 523 in conjunction with external action, avoiding waste.

[0033] Furthermore, in order to facilitate the disassembly and cleaning of the rinsing mechanism 5, and to maintain stability during normal use, as a preferred embodiment of the present invention, a third groove 512 is provided at both ends of the third plate 51, and a U-shaped block 511 is inserted into the inner wall of each of the two third grooves 512. The two U-shaped blocks 511 are respectively fastened to the second housing 12 and the inspection door 13 by the second bolts. Specifically, by setting the third tank 512 and the U-shaped block 511, it can be firmly fixed on the second housing 12 and the inspection door 13 without shaking during normal operation. When the nozzle needs to be cleaned or repaired after a long period of use, the entire set of components can be disassembled directly by unscrewing the bolts and pulling out the U-shaped block 511, which is convenient and quick.

[0034] It is important to note here that: [combination] Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the U-shaped block 511 runs horizontally through the second housing 12, and then combined with... Figure 8Although the opening of the third groove 512 faces upward and the opening of the U-shaped block 511 faces downward, it also indicates that the U-shaped block 511 is connected to the second housing 12 and the access door 13 by bolts. Therefore, during installation, simply insert the U-shaped block 511 horizontally into the second housing 12. Because the second housing 12 has a wall thickness, the U-shaped block 511 can rest on the second housing 12 and the access door 13. In this way, the U-shaped block 511 will not be affected by the third groove 512 and fall down. Then, from top to bottom, the U-shaped block 511 is secured to the third groove 512, and finally, it is locked with bolts.

[0035] Furthermore, in order to avoid increasing the total amount of cleaning fluid inside the first housing 11 due to external water supply, and also to avoid reducing the original concentration and ratio of the cleaning fluid inside the first housing 11, as a preferred embodiment of the present invention, the water supply mechanism 6 includes a second pipe 61 and a three-way valve 62. One end of the second pipe 61 is fixedly connected to the bottom surface of the first housing 11, the other end of the second pipe 61 is fixedly connected to the first end of the three-way valve 62, the second end of the three-way valve 62 is fixedly connected to the external sewage discharge pipe, and the third end of the three-way valve 62 is fixedly connected to the input end of the external water supply equipment. Specifically, by setting up a water supply mechanism 6, the cleaning fluid at the bottom of the first housing 11 is directly drawn up using an external water supply device and a three-way valve 62 to be used by the water spray assembly 52, thus realizing the self-circulation of the cleaning fluid inside the equipment. This eliminates the need to add extra clean water, ensuring that the original concentration ratio of the cleaning fluid is not diluted. After the entire batch of cleaning is completed, the external water supply device is turned off and the flow path of the three-way valve 62 is switched, allowing the dirty water to be drained directly.

[0036] Furthermore, in order to save energy and avoid adding an additional power source, as a preferred embodiment of the present invention, the drive mechanism 4 includes a reversing component 42, a reset component 43, a transmission component 44, a force receiving component 45, and a plurality of thrust components 41. One end of the reset component 43 is connected to the outer wall of the second housing 12, and the other end of the reset component 43 is connected to one end of the transmission component 44. The other end of the transmission component 44 extends into the interior of the second housing 12 and is connected to both the reversing component 42 and the force receiving component 45. The other end of the force receiving component 45 is connected to the second housing 12. The other end of the reversing component 42 is connected to the valve stem of the valve 523. One end of each of the plurality of thrust components 41 is connected to one end of a plurality of V-shaped plates 22, and the other ends of the plurality of thrust components 41 are aligned with the position of the force receiving component 45. Specifically, by setting up the drive mechanism 4, the moving force of the conveyor belt 14 carrying the motor housing forward is utilized. As soon as the profile comes over and touches it, the force can be automatically transmitted to open the valve 523 to flush the water. When the profile leaves, the valve 523 will automatically close. The whole process is purely mechanical linkage, without the need for additional sensors or electrical control equipment, which saves electricity and is less prone to failure.

[0037] Furthermore, in order to apply the force of the limiting mechanism 2 and the conveyor belt 14 when they move to the force-receiving component 45, as a preferred embodiment of the present invention, the thrust component 41 includes a second rod 411 and a full gear 412. One end of the second rod 411 is fixedly connected to one end of the V-shaped plate 22, and the other end of the second rod 411 is fixedly connected to the shaft of the full gear 412. Specifically, by setting the thrust assembly 41, the second rod 411 and the full gear 412 are kept firmly fixed and move forward together with the V-shaped plate 22. In this way, the full gear 412 will not rotate randomly due to equipment vibration on the way. It can be ensured that the angle of the teeth is in a fixed facing state every time it is pushed in, and it is precisely embedded in the half gear 451 of the force-bearing assembly 45. The thrust of straight-line movement is converted into the force of turning the gear, without slipping or jamming.

[0038] It should be noted that in actual use, the gear 412 can also be set as a rack that does not come into contact with the conveyor belt 14, and there is no specific limitation.

[0039] Furthermore, in order to promptly shut off the water supply mechanism 6 after the limiting mechanism 2 passes through the rinsing range of the rinsing mechanism 5, as a preferred embodiment of the present invention, the reset assembly 43 includes a second block 431, a spring 432, a rack plate 433, and a spur gear 434. One side of the second block 431 is fixedly connected to the outer wall of the second housing 12, and the other side of the second block 431 is fixedly connected to one end of the spring 432. The other end of the spring 432 is fixedly connected to one end of the rack plate 433. The shaft of the spur gear 434 is connected to the transmission assembly 44. The rack plate 433 and the spur gear 434 mesh. The end of the rack plate 433 near the spring 432 is slidably connected to the second block 431 through a guide rod. Specifically, by setting up the reset component 43, the spring 432 is stretched and has strong rebound characteristics. Once the profile is washed and leaves, the thrust of the thrust component 41 disappears, and the spring 432 immediately pulls the spur gear 434 back through the rack plate 433, bringing the entire transmission system back to its original position and quickly shutting off the water valve. This saves water flow and prepares the space for the next profile.

[0040] It should be noted that when the equipment is in standby mode or the profile has not yet reached the washing area, the spring 432 is in a naturally contracted state. At this time, the basic tension it provides will keep the spur gear 434 firmly in the initial position, ensuring that the internal valve 523 is in an absolutely closed state. When the thrust assembly 41 starts to move the force receiving assembly 45, the entire transmission system will transmit the forward thrust to the top. When the third rod 441 rotates, it will rotate the spur gear 434 together. Then, the rotating spur gear 434 will pull the rack plate 433 to move away from the second block 431 by meshing.

[0041] As the rack plate 433 is continuously pulled away by external force along this trajectory, the spring 432 is forced from its normal state into a continuously stretched state of force, and quickly accumulates rebound potential energy inside. Once the profile moves away, the external thrust instantly drops to zero, and the spring 432, which is in a stretched state of force, will immediately release its potential energy and contract, quickly pulling the rack plate 433 back to its normal initial position along the previous motion trajectory. Thus, the spur gear 434 drives the entire mechanical linkage structure to cleanly and neatly complete the water shut-off action.

[0042] Furthermore, in order to ensure that the thrust received by the force-receiving component 45 from the thrust component 41 is applied to the reversing component 42 and the reset component 43 in a timely and accurate manner, as a preferred embodiment of the present invention, the transmission component 44 includes a third rod 441, a chain 442 and two sprockets 443. One end of the third rod 441 is fixedly connected to the shaft of the spur gear 434, and the other end of the third rod 441 extends into the interior of the second housing 12 and is fixedly connected to the shaft of the first sprocket 443. The end of the third rod 441 located inside the second housing 12 is also connected to the reversing component 42. The second sprocket 443 is connected to the force-receiving component 45, and the chain 442 meshes with both sprockets 443. Specifically, by setting up a transmission component 44, the rotation of the lower gear is steadily transmitted to the upper third rod 441 using a chain 442 and sprockets 443 at both ends. The chain 442 transmission is not as prone to slippage as a belt, ensuring that as long as there is force below, the opening of the upper valve 523 can keep up precisely, with no delay in action.

[0043] Furthermore, in order to convert the lateral force received by the transmission assembly 44 into a rotational force that can open and close the valve 523, as a preferred embodiment of the present invention, the reversing assembly 42 includes a first bevel gear 421 and a second bevel gear 422. The axis of the first bevel gear 421 is fixedly connected to the valve stem of the valve 523, and the axis of the second bevel gear 422 is fixedly connected to one end of the third rod body 441 located inside the second housing 12. The first bevel gear 421 and the second bevel gear 422 mesh. Specifically, by setting up the reversing component 42, and utilizing the characteristic that the first bevel gear 421 and the second bevel gear 422 mesh vertically with each other, the horizontal rotational force of the third rod 441 is turned by 90° and transformed into the force that rotates the valve stem of the valve 523, thus smoothly completing the action of the water circuit switch.

[0044] Furthermore, in order to be able to sense the thrust of the thrust assembly 41 in a timely manner, as a preferred embodiment of the present invention, the force-receiving assembly 45 includes a half gear 451 and a fourth rod 452. One end of the fourth rod 452 is rotatably connected to the first housing 11 through a sealed bearing, and the other end of the fourth rod 452 is fixedly connected to the axis of the half gear 451. The half gear 451 matches the full gear 412, and the half gear 451 meshes with the contacting full gear 412. The outer wall of the fourth rod 452 is fixedly connected to the axis of the second sprocket 443. Specifically, by setting the force-bearing component 45, the half gear 451 normally stays quietly in its original position. When the full gear 412 on the thrust component 41 comes over and meshes with it, it can immediately start to rotate, and at the same time drive the fourth rod 452 to rotate synchronously, turning the sensed travel signal into a real rotation signal and transmitting it to the next level.

[0045] Furthermore, in order to shield the thrust assembly 41 located at the exposed parts at both ends of the second housing 12 and to improve the overall aesthetics, as a preferred embodiment of the present invention, two third housings 3 are fixedly connected to the surface of the limiting rail 15 near the drive mechanism 4. Each of the two third housings 3 has a first groove 31 extending through it on the side near the conveyor belt 14. The height of the first groove 31 is not less than the diameter of the second rod 411, and the size of the inner wall of the third housing 3 is not less than the diameter of the full gear 412. The full gear 412 is located inside the third housing 3, and the two third housings 3 are located on both sides of the second housing 12. Specifically, by setting up the third housing 3, it is equivalent to covering the exposed thrust assembly 41 with a narrow protective cover. The first groove 31 leaves a gap so that the second rod 411 can slide smoothly through, while safely enclosing the gear 412 inside, avoiding the danger of workers accidentally touching the gear when walking around. The overall appearance is also neater and more aesthetically pleasing.

[0046] Working principle: Before use, the staff first moves the positioning components 23 on all V-shaped plates 22 to a position that can match any hole (hereinafter referred to as the corresponding hole) of the aluminum alloy motor housing profile (hereinafter referred to as the profile) according to the second groove 222. Then, the position of the first rod 231 is restricted by the nut 233 and the two sides of the first block 232. After that, it can be used.

[0047] When in use, the staff aligns the corresponding hole of the first profile with the first rod 231 of the positioning component 23 and inserts it. At this time, due to the restriction of the first rod 231 and the corresponding hole, each profile is in a specific position (or angle) when it moves with the conveyor belt 14.

[0048] Then, when the first profile moves along the conveyor belt 14 to the wavy line area (e.g. Figure 4 As shown (direction from left to right), the profile first descends below the surface of the cleaning fluid inside the first housing 11, that is, it is completely immersed in the cleaning fluid. At this time, the profile can be cleaned for the first time by the ultrasonic transducer and other equipment located inside the first housing 11.

[0049] Then, when the profile begins to rise along with the conveyor belt 14, the full gear 412 of the thrust assembly 41 connected to the V-shaped plate 22 can contact the half gear 451 on the force-receiving assembly 45 located at a specific position, and push the half gear 451 (at this time, because the full gear 412 is fixed to the second rod 411, it does not rotate on its own, but pushes the half gear 451 to rotate like a rigid rack). After the half gear 451 rotates, it can drive the sprocket 443 connected to it to rotate through the fourth rod 452. Then the chain 442 can drive the third rod 441 to rotate through another sprocket 443. When the third rod 441 rotates, it can drive the second bevel gear 422 and the spur gear 434 to rotate at the same time.

[0050] When the second bevel gear 422 rotates, it drives the first bevel gear 421 and the valve stem of the valve 523 connected to it to rotate, thereby opening the water passage inside the first pipe 522. At this time, an external water supply device (such as a water pump) can draw the cleaning fluid inside the first housing 11 through the three-way valve 62 and the second pipe 61, and then deliver it through the first pipe 522 to the nozzle of the spray pipe 521 for spraying. Figure 4 As shown, the nozzle of the spray pipe 521 is tilted downwards, precisely to rinse the end face of the profile that is beginning to "slope". The tilted state of the profile also helps the cleaning fluid to flow smoothly into the deep holes and dispel any residual air bubbles inside. Furthermore, because... Figure 6 As shown, several nozzles are arranged in a row, so what is sprayed is not a single straight water column, but a large curtain of water cascading down. The width of this water curtain is enough to cover the entire end face of the profile. In this way, without the need for deliberate aiming, all the threaded holes and grooves on the end face can be washed in one go, and it can perfectly handle various types of profiles produced on the mixed production line.

[0051] When the spur gear 434 rotates, it pulls the spring 432 through the rack plate 433, causing the spring 432 to lengthen. When the full gear 412 of the thrust assembly 41 disengages from the half gear 451, the spring 432 resets, thereby pulling the rack plate 433 back to its original position. At the same time, the spur gear 434 connected to the rack plate 433, the third rod 441, and the sprocket 443 and the second bevel gear 422 on the third rod 441 will all reset, thereby driving the valve 523 to close the water passage in the first pipe 522 to wait for the arrival of the next profile.

[0052] Afterwards, the profile continues to move and begins to "go downhill". At this time, the profile that has already been rinsed by ultrasonic waves can be cleaned again. Then, when the profile goes "uphill" again, the angle of inclination allows the accumulated liquid in the threaded holes or grooves to flow out automatically. After that, the profile enters the draining area and drying area (this is existing technology and will not be described in detail here) and then passes out from the other end of the second housing 12. At this time, the staff can remove the profile from the V-shaped plate 22, which is convenient, quick and easy to operate.

[0053] After the entire batch of work is completed, the cleaning wastewater inside the first housing 11 can be directly discharged to the external sewage pipe by switching the flow direction of the three-way valve 62.

[0054] Finally, it is worth noting that when the conveyor belt 14 and the limiting track 15 push the limiting mechanism 2 toward the rising ramp of the undulating wave area, the motor housing profile fastened to the V-shaped plate 22 will generate a clear axial tilt angle. Because a specific clamping posture was previously locked by the positioning component 23, as the tilt angle increases, the openings of the threaded holes of varying depths and complex grooves will naturally switch to a downward-facing physical orientation. Under the action of this angle difference, the washing liquid that was originally hidden in the deep cavity blind hole and could not flow out due to surface tension will have its own gravity exceed the adhesion of the liquid film, and will naturally slide down the slope of the hole wall, eventually flowing back into the first housing 11 at the bottom. This design, which relies on the geometric slope to change the fluid force balance, not only efficiently realizes the automatic emptying of the internal stagnant water, but also reduces the drying load for subsequent entry into the draining and drying areas.

[0055] Furthermore, the aforementioned method of automatically draining accumulated liquid by tilting the profile end face is more effective for blind holes and deep cavities with axial distribution: when the conveyor belt 14 drives the profile along the uphill trajectory to generate an upward angle, the bottom surface of the blind end of such axial holes is relatively raised in the spatial coordinate system, and the cleaning liquid retained inside breaks the static balance and slides smoothly along the inclined hole wall. As for the radial auxiliary threaded holes that may exist on the side wall of the profile, in the initial stage of fixing them to the limiting mechanism 2, the clamping posture can be pre-intervened by the rotation positioning component 23 to ensure that the opening of the key radial hole faces the side or downward. In this way, the drainage advantage can be fully utilized in the subsequent wave-like undulating flow, thereby ensuring that more threaded holes and grooves are free of residual liquid accumulation.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended technical solutions and their equivalents.
