Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and particularly to an outer surface cleaning device and method for the production of automotive drive shafts. Background Art

[0002] During the production process of automotive drive shafts, they come into contact with various oils, dust, and other impurities. If these impurities are not removed in a timely manner, it will affect the running accuracy of the drive shaft, and may even lead to increased wear, shortening its service life. Moreover, a protective layer is usually applied to the surface of the drive shaft. If the drive shaft is not cleaned thoroughly, it will affect the subsequent application of the protective layer, thus affecting the actual use of the drive shaft.

[0003] The publication number CN119346521A discloses a cleaning device for the production of automotive parts. The problems raised in its background art are as follows: Currently, when using a drum to clean automotive parts, multiple automotive parts are often placed inside a cleaning cylinder. When the cleaning cylinder drives the automotive parts to rotate, they will collide with each other, and it is easy to cause damage. At the same time, after the automotive parts are cleaned, water stains will adhere to their surfaces, and it is necessary for workers to manually dry them, increasing the labor intensity of the workers.

[0004] Based on the existing technologies, the following problems exist:

[0005] When the existing automotive drive shaft cleaning equipment is cleaning, it usually cleans by immersing the drive shaft in a cleaning liquid or by spraying. And to reduce collisions between drive shafts, the positions of the drive shafts are relatively fixed. As a result, it is not convenient to expose the rotating parts at the ends of the drive shaft and the telescopic parts in the middle, making it not convenient to clean them thoroughly, and there are certain deficiencies. Referring to the above application document, it only uses a partition method to place automotive parts in different positions to reduce collisions between components, and there are certain deficiencies. To solve the above problems, an outer surface cleaning device and method for the production of automotive drive shafts are proposed. Summary of the Invention

[0033] The present invention also provides a usage method of an outer surface cleaning device for automobile drive shaft production. Using the outer surface cleaning device for automobile drive shaft production described above, the method includes the following steps:

[0034] S1: Fix the end of the drive shaft to be cleaned through the adjusting mechanism;

[0035] S2: After the drive shaft is fixed, clean the drive shaft through the cleaning mechanism. During the cleaning process, adjust the posture of the drive shaft through the adjusting mechanism to clean the articulated part and the telescopic part of the drive shaft.

[0036] The present invention provides an outer surface cleaning device and method for automobile drive shaft production. Compared with the prior art, the following beneficial effects are achieved:

[0037] 1. Through the cooperation of the cleaning mechanism and the adjusting mechanism, the end of the drive shaft deflects and pulls the end of the drive shaft, so as to facilitate cleaning the rotating part and the telescopic part of the drive shaft, etc., thereby improving the comprehensiveness of cleaning the drive shaft, and facilitating multi-directional cleaning of the drive shaft, improving the cleaning effect, and being applicable to drive shafts of different sizes.

[0038] 2. Through the moving component, while the first plate body and the second plate body fit the shape of the drive shaft, the moving distance of the arc-shaped first plate body in the arc-shaped second plate body is increased, thereby further increasing the cleaning range of the first nozzle for the drive shaft, and ensuring that the movement of the second plate body is not hindered, so as to ensure the stability of the position adjustment of the first nozzle.

[0039] 3. The adjusting mechanism limits the two ends of the drive shaft. Thus, under the action of the universal joint of the drive shaft, the end of the drive shaft deflects relative to the middle part of the drive shaft, so as to facilitate cleaning the gap at the rotating position, etc. While facilitating the fixing of the drive shaft, the cleaning effect is improved.

[0040] 4. The electric push rod in the present invention facilitates the adjustment of the position of the third mounting plate, thereby facilitating the adjustment according to the length of the transmission shaft. Moreover, through the cooperation of the first adjustment component, the second adjustment component and the third adjustment component, it is convenient to fix transmission shafts of different sizes.

[0041] 5. The second adjustment component in the present invention facilitates the exposure of the end of the transmission shaft. When the end of the transmission shaft deflects, and when the deflection degree is greater than the rotation amount of the universal joint of the transmission shaft, the telescopic part in the middle of the transmission shaft expands and contracts, so that the telescopic part is exposed, further improving the comprehensiveness of cleaning. And the electric push rod facilitates pulling both ends of the transmission shaft, so that when the second adjustment component cannot fully expose the telescopic part, the telescopic part is fully expanded by pulling both ends of the transmission shaft to avoid affecting the cleaning effect.

[0066] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0067] Embodiment 1: Please refer to Figure 1 、 Figure 2 and Figure 3 , an outer surface cleaning device for the production of an automotive drive shaft 4, including a machine body 1, a drive shaft 4, and a frame 2 fixed inside the machine body 1. The frame 2 is U-shaped, and the opening of the frame 2 faces the front of the machine body 1, so that after opening the machine door of the machine body 1, the drive shaft 4 to be cleaned can be placed in the frame 2 along the opening of the frame 2. This is the prior art and will not be elaborated here. It also includes an adjusting mechanism 3 spaced between the inner top and inner bottom of the frame 2 for adjusting the posture of the drive shaft 4 and a cleaning mechanism 5 arranged outside the adjusting mechanism 3 for cleaning the drive shaft 4. The adjusting mechanisms 3 are arranged symmetrically with respect to the center point of the frame 2;

[0068] Please refer to Figure 4 、 Figure 7 and Figure 8 , the cleaning mechanism 5 includes:

[0069] A first plate body 53 is arranged to be lifted on the outside of the adjusting mechanism 3. A second plate body 52 that can move along an annular track is sleeved on the side of the first plate body 53 close to each other. First nozzles 51 are fixedly arranged at the centers of the inner sides of the first plate body 53 and the second plate body 52. First electromagnets 57 are fixedly arranged opposite to each other at the center of the inside of the first plate body 53. Second electromagnets 56 are fixedly arranged on the sides of the second plate body 52 close to each other, so that the second plate body 52 moves along an annular track in the first plate body 53. A moving component 55 that cooperates with the second electromagnet 56 to further drive the movement of the first plate body 53 is arranged inside the first plate body 53. A lifting component 54 for adjusting the height of the first plate body 53 is arranged on the top of the first plate body 53.

[0070] The first plate body 53 is designed to be hollow, and the side wall of the second plate body 52 fits against the inner wall of the first plate body 53 and is in a sealed design;

[0071] Both the first plate body 53 and the second plate body 52 are designed to be arc-shaped, and the first plate body 53 and the second plate body 52 are connected to form a ring body to clean the side wall of the drive shaft 4.

[0072] In specific implementation, when the end of the transmission shaft 4 is fixed by the adjusting mechanism 3 and initially, the two ends of the transmission shaft 4 do not deflect, that is, the transmission shaft 4 is in a vertical state. At this time, the cleaning liquid pipeline is externally connected to the first nozzle 51 to clean the side wall of the transmission shaft 4, and the horizontal position and height of the first nozzle 51 are adjusted by the cooperation of the moving component 55 and the lifting component 54, so as to facilitate cleaning the transmission shaft 4 from multiple directions;

[0073] Since the ends of the transmission shaft 4 and the telescopic part in the middle are connected by universal joints, the two ends of the telescopic part in the middle of the transmission shaft 4 can rotate relative to each other to meet the actual transmission requirements of the vehicle. Therefore, in order to fully clean the rotating part of the transmission shaft 4, the angles of both ends of the transmission shaft 4 are adjusted by the adjusting mechanism 3 to expose the rotating part. At this time, the cleaning liquid pipeline is externally connected to the second nozzle 6, and the two ends of the transmission shaft 4 are cleaned from the top and bottom through the second nozzle 6, and in cooperation with the first nozzle 51, it is convenient to comprehensively clean the transmission shaft 4 and improve the cleaning effect.

[0074] Please refer to Figure 7 、 Figure 8 and Figure 9 ,The moving component 55 includes:

[0075] The moving rod 554 is sleeved on the inner wall of the bottom of the first plate body 53. A third electromagnet 557 is embedded on the side wall of one end of the moving rod 554 located inside the first plate body 53 and facing the second electromagnet 56;

[0076] The retaining ring 553 is fixedly sleeved on the side wall of one end of the moving rod 554 located at the bottom of the first plate body 53 to limit the height of the moving rod 554 entering the first plate body 53, so that there is a gap between the top of the moving rod 554 and the inner wall of the top of the first plate body 53. A retaining rod 552 is fixedly provided at the bottom of the moving rod 554;

[0077] The mounting cover 551 is fixedly provided at the bottom of the first plate body 53, and a through groove adapted to the retaining rod 552 is opened at the bottom of the mounting cover 551. The cross section of the retaining rod 552 is designed as a regular hexagon to prevent the moving rod 554 from deflecting. A first spring is sleeved on the side wall of one end of the retaining rod 552 located inside the mounting cover 551 and at the bottom of the retaining ring 553.

[0078] The moving component 55 further includes:

[0079] The bottom plate 555 is fixedly arranged on one side of the second plate body 52 close to each other and is located at the outer circle of the second plate body 52, so as to contact the moving rod 554 prior to the second plate body 52, and squeeze the moving rod 554 from the gap at the top of the moving rod 554. The lower end of the side of the bottom plate 555 close to the moving rod 554 and the top of the moving rod 554 are both arc-shaped, and the bottom of the bottom plate 555 is inclined;

[0080] The limiting inclined plane 556 is opened on one side of the second plate body 52 close to each other and is smoothly connected to the inclined part of the bottom of the bottom plate 555, so as to enable the second plate body 52 to squeeze the moving rod 554 after the bottom plate 555 squeezes the moving rod 554.

[0081] In specific implementation, by sleeving the second plate body 52 in the first plate body 53, a repulsive force is generated on the side where the first electromagnet 57 and the second electromagnet 56 are close to each other, thereby driving the second plate body 52 to move in a circular motion within the first plate body 53, so as to adjust the position of the first nozzle 51 on the inner side of the second plate body 52, and clean the transmission shaft 4 from multiple directions to improve the cleaning effect;

[0082] To fit the shape of the transmission shaft 4, by making the first plate body 53 and the second plate body 52 form a ring shape after being connected and combined, it is convenient to clean the transmission shaft 4 from multiple directions. And to increase the moving distance of the arc-shaped first plate body 53 within the arc-shaped second plate body 52, thereby further increasing the cleaning range of the first nozzle 51 for the transmission shaft 4, the moving assembly 55 is set. When the moving assembly 55 is specifically implemented, when the first electromagnet 57 and the second electromagnet 56 are restricted by the circular shape and cannot drive the second plate body 52 to move through the repulsive force, the extrusion of the moving rod 554 by one side of the second plate body 52 is cancelled, so that the moving rod 554 moves upward under the action of the first spring. At this time, the third electromagnet 557 and the second electromagnet 56 are arranged facing each other, and thus a repulsive force is generated by the second electromagnet 56 and the third electromagnet to drive the second plate body 52 to move, thereby further increasing the moving distance of the second plate body 52, so as to flexibly adjust the position of the first nozzle 51 for cleaning the transmission shaft 4, and thus it is convenient to clean the transmission shaft 4 from multiple directions. When the extrusion of the moving rod 554 on the same side by the first plate body 53 is cancelled, the other side of the second plate body 52 contacts and squeezes the moving rod 554 on the other side downward through the action of the bottom plate 555, so as to facilitate the subsequent extrusion of the moving rod 554 on the other side to the bottom of the second plate body 52 by the other side of the second plate body 52 through the limiting inclined plane 556, so that the second plate body 52 has enough moving space within the first plate body 53 and the movement of the second plate body 52 is not blocked, so as to ensure the stability of the position adjustment of the first nozzle 51.

[0083] When adjusting the position of the second plate body 52 on the first plate body 53, the first electromagnet 57 on one side of the first plate body 53 cooperates with the second electromagnet 56 on the same side. At this time, the first electromagnets 57 and the second electromagnets 56 on the other sides of the first plate body 53 and the second plate body 52 do not act, so that the second plate body 52 can move within the first plate body 53, or there is a difference in the repulsive forces generated on both sides, so that the second plate body 52 can perform a circular motion within the first plate body 53 while limiting the position of the second plate body 52 to improve the stability of the second plate body 52;

[0084] By squeezing the moving rod 554 with the second plate body 52, and in order to make the second plate body 52 move smoothly to the top of the moving rod 554, the abutting plate 555 first contacts the moving rod 554, so as to facilitate squeezing the moving rod 554 through the gap at the top of the moving rod 554, and by setting the limiting inclined surface 556, the second plate body 52 squeezes the moving rod 554, so as to facilitate the second plate body 52 to smoothly squeeze the moving rod 554, and make the second plate body 52 fit with the inner wall of the first plate body 53 except at the position of the limiting inclined surface 556, so as to improve the stability of the movement of the second plate body 52;

[0085] By making the side wall of the second plate body 52 fit with the inner wall of the first plate body 53 and adopting a sealing design, a dynamic seal can be formed between the second plate body 52 and the first plate body 53 to prevent water stains such as cleaning liquid from entering the first plate body 53 when the second plate body 52 moves. And by setting the mounting cover 551, the blocking rod 552 moves along the mounting cover 551, and a dynamic seal design can be adopted between the blocking rod 552 and the mounting cover 551, so as to avoid affecting the normal use of the first electromagnet 57 and the second electromagnet 56, etc.;

[0086] By setting the blocking rod 552 to limit the vertical movement of the moving rod 554, the third electromagnet 557 always faces the second electromagnet 56 to ensure the stability of the use of the third electromagnet 557 and the second electromagnet 56.

[0087] Please refer to Figure 4 、 Figure 5 and Figure 6 , the lifting assembly 54 includes:

[0088] The guide rod 541 is fixedly arranged on the top of the first plate body 53. The top of the guide rod 541 extends to the top of the machine body 1 along the third mounting plate 34, the second mounting plate 33 and the first mounting plate 32. Guide holes for sleeving the guide rod 541 are opened at the tops of the third mounting plate 34, the second mounting plate 33 and the first mounting plate 32, and first sliders are fixedly arranged on the inner walls of the guide holes. First chutes 544 are opened on the back sides of the side walls of the guide rod 541. The first sliders are placed in the first chutes 544 to limit the lifting of the guide rod 541. The third toothed plate 542 is embedded in the front side of the side wall of the guide rod 541;

[0089] The rotating rod 543 is rotatably arranged at the top of the third mounting plate 34. Second gears meshing with the third toothed plate 542 are fixedly sleeved at both ends of the side wall of the rotating rod 543. A third servo motor for driving the rotating rod 543 to rotate is fixedly arranged at the top of the third mounting plate 34. A rotating hole for mounting the rotating rod 543 is formed in the side wall of the connecting rod.

[0090] During specific implementation, the third servo motor is started. The output shaft of the third servo motor drives the rotating rod 543 to rotate. The rotating rod 543 drives the first plate body 53 to move through the second gear and the third toothed plate 542, thereby adjusting the height of the first nozzle 51.

[0091] By slidably connecting the guide rod 541 with the first mounting plate 32 and the second mounting plate 33, the stability of the vertical movement of the guide rod 541 and the first nozzle 51 is improved.

[0092] The output shaft of the third servo motor is fixedly provided with a first rotating shaft through a coupling. The first rotating shaft and the rotating rod 543 are connected by a gear and a chain drive, so that the third servo motor drives the rotating rod 543 to rotate. This is the prior art and will not be elaborated here.

[0093] Embodiment 2: Please refer to Figure 10 , Figure 12 and Figure 15 . The different technical solution of this embodiment compared with Embodiment 1 is that the adjusting mechanism 3 includes:

[0094] The first mounting plate 32 is fixedly arranged at the inner top of the frame 2. An electric push rod 31 is fixedly arranged at the center of the bottom of the first mounting plate 32. The telescopic shaft of the electric push rod 31 is fixedly provided with a connecting rod. The bottom of the connecting rod is fixedly provided with a third mounting plate 34. The bottom of the third mounting plate 34 is hinged with first limiting plates 35 arranged symmetrically with respect to the center point of the third mounting plate 34. The bottoms of the first limiting plates 35 are hinged with second limiting plates 37 designed in a bent shape. First adjusting components 38 and second adjusting components 39 for adjusting the angles of the first limiting plates 35 and the second limiting plates 37 are respectively arranged at the bottom of the third mounting plate 34 and the bottom of the first limiting plates 35. Limiting rods 36 are movably arranged at the inner tops of the second limiting plates 37 to limit the ends of the transmission shaft 4 through the limiting rods 36 and the second limiting plates 37. A third adjusting component 30 for adjusting the position of the limiting rods 36 is arranged inside the second limiting plates 37.

[0095] The second mounting plate 33 is fixedly sleeved at the middle end of the side wall of the electric push rod 31, and the telescopic shaft of the electric push rod 31 is located at the bottom of the second mounting plate 33. The top of the second mounting plate 33 is fixedly provided with mounting rods arranged in an annular array, and the tops of the mounting rods are fixedly connected with the bottom of the first mounting plate 32.

[0096] In specific implementation, the flange holes of the flange at the end of the transmission shaft 4 are sleeved on the side wall of the limiting rod 36. Immediately afterwards, the positions of the first limiting plate 35, the second limiting plate 37 and the limiting rod 36 are adjusted through the first adjusting assembly 38, the second adjusting assembly 39 and the third adjusting assembly 30 to fix the end of the transmission shaft 4, so as to facilitate the installation of the transmission shaft 4 inside the frame 2 for subsequent cleaning. And by limiting both ends of the transmission shaft 4, under the action of the universal joint of the transmission shaft 4, the end of the transmission shaft 4 deflects relative to the middle part of the transmission shaft 4, so as to facilitate the cleaning of the gap at the rotating position, etc. While facilitating the fixing of the transmission shaft 4, the cleaning effect is improved;

[0097] The electric push rod 31 facilitates the adjustment of the position of the third mounting plate 34, so as to facilitate the adjustment according to the length of the transmission shaft 4. And through the cooperation of the first adjusting assembly 38, the second adjusting assembly 39 and the third adjusting assembly 30, it is convenient to fix transmission shafts 4 of different sizes. The second adjusting assembly 39 rotates the second limiting plate 37, so that the end of the transmission shaft 4 deflects, so as to facilitate the exposure of the end of the transmission shaft 4. When the end of the transmission shaft 4 deflects, when the deflection degree is greater than the rotation amount of the universal joint of the transmission shaft 4, the telescopic part in the middle of the transmission shaft 4 expands and contracts, so that the telescopic part is exposed, further improving the comprehensiveness of cleaning. And the electric push rod 31 facilitates pulling both ends of the transmission shaft 4, so that when the second adjusting assembly 39 cannot completely expose the telescopic part, the telescopic part is completely unfolded by pulling both ends of the transmission shaft 4 to avoid affecting the cleaning effect;

[0098] The inner diameter of the ring formed by the first plate body 53 and the second plate body 52 is larger than the maximum occupied space after the maximum-sized transmission shaft 4 deflects, so as to ensure that the first plate body 53 and the second plate body 52 can move vertically along the side wall of the transmission shaft 4. In specific design, the ring mechanism formed by the first plate body 53 and the second plate body 52 can be adapted to the maximum size of the transmission shaft 4 for convenient actual use, which will not be elaborated here.

[0099] Please refer to Figure 12 、 Figure 13 and Figure 14 , the third adjusting assembly 30 includes:

[0100] The adjustment seat 301 is fixedly arranged inside the second limiting plate 37. The inside of the adjustment seat 301 is designed to be hollow. On the inner wall of the adjustment seat 301 on the side away from the limiting rod 36, a fourth electromagnet 303 is fixedly arranged. And a fifth electromagnet 304 is sleeved on the inner wall of the adjustment seat 301. On the side of the fifth electromagnet 304 close to the limiting rod 36, an adjustment rod 307 extending outside the adjustment seat 301 is fixedly arranged. An adjustment hole for sleeving the adjustment rod 307 is formed in the side wall of the adjustment seat 301. And the inner diameter of the inner wall of the adjustment hole is smaller than the side wall diameter of the fifth electromagnet 304. First toothed plates 305 are embedded on both sides of the adjustment rod 307;

[0101] The adjustment plate 306 is slidably arranged inside the second limiting plate 37. And second toothed plates 308 adapted to the first toothed plates 305 are fixedly arranged on the mutually approaching sides of the adjustment plate 306. Inside the second limiting plate 37 and between the second toothed plate 308 and the first toothed plate 305, a transmission gear 309 meshing with the first toothed plate 305 and the second toothed plate 308 is rotatably arranged. So that when the adjustment rod 307 approaches the limiting rod 36, the limiting rod 36 is driven to approach the adjustment seat 301. On the front ends of the mutually approaching sides of the adjustment plate 306, mounting blocks are fixedly arranged. The top of the mounting block is fixedly connected to the bottom of the limiting rod 36. An installation groove for installing the third adjustment assembly 30 is formed in the inside of the second limiting plate 37. Water guide holes 302 arranged at intervals are formed in the bottom inner wall of the installation groove. And an installation through groove communicating with the installation groove and for allowing the limiting rod 36 to move is formed in the top of the second limiting plate 37.

[0102] Please refer to Figure 11 , the first adjustment assembly 38 includes:

[0103] The first hinge shaft 381 is arranged at the bottom of the third mounting plate 34 and is used for hinging the top of the first limiting plate 35 to the bottom of the third mounting plate 34. A first gear is fixedly sleeved on the side wall of one of the first hinge shafts 381. A first transmission mechanism 382 for driving connection with the first gear is arranged on the side wall of the other first hinge shaft 381. So that when the two first limiting plates 35 rotate, the bottoms of the first limiting plates 35 approach each other or move away from each other. A first servo motor for driving one of the first hinge shafts 381 to rotate is fixedly arranged at the bottom of the third mounting plate 34;

[0104] Please refer to Figure 12 , the second adjustment assembly 39 includes:

[0105] The second hinge shaft 392 is arranged at the connection of the second limiting plate 37 and the third limiting plate and is used for hinging the top of the second limiting plate 37 to the bottom of the first limiting plate 35. A second servo motor is fixedly arranged on the side wall of the first limiting plate 35. A second transmission mechanism 391 for driving connection with the second hinge shaft 392 is arranged on the output shaft of the second servo motor.

[0106] In the specific implementation, after the flange hole of the flange plate at the end of the transmission shaft 4 is sleeved on the side wall of the limiting rod 36, the fourth electromagnet 303 and the fifth electromagnet 304 are started, so that the fourth electromagnet 303 and the fifth electromagnet 304 generate a repulsive force on the side close to each other, so as to drive the adjustment rod 307 and the first tooth plate 305 to move through the repulsive force, so that under the action of the transmission gear 309, the first tooth plate 305 and the second tooth plate 308, the adjustment plate 306 and the limiting rod 36 are driven to approach the position of the adjustment seat 301, so that the limiting rod 36 tightens the flange plate of the transmission shaft 4, thereby adjusting the end of the transmission shaft 4. After the end of the transmission shaft 4 is fixed, at this time, since the bottom of the first limit plate 35 rotates in a trajectory of approaching or moving away from each other, the end of the transmission shaft 4 can be in a vertical state relative to the middle part of the transmission shaft 4, so as to facilitate the initial cleaning of the transmission shaft 4. When it is necessary to clean the rotating part of the end of the transmission shaft 4, the angle of the second limit plate 37 is adjusted by the second adjustment component 39, so that the end of the transmission shaft 4 is deflected. At this time, the first nozzle 51 and the second nozzle 6 cooperate to clean the gap at the rotating part of the transmission shaft 4, thereby improving the cleaning effect;

[0107] When the first adjustment component 38 is specifically operated, the first servo motor is started, and the output shaft of the first servo motor drives the first hinge shaft 381 to rotate. The first hinge shaft 381 drives the other first hinge shaft 381 to rotate in the opposite direction through the first transmission mechanism 382 and the first gear, so that the bottoms of the first limit plates 35 move closer to or away from each other. The first transmission mechanism 382 uses gear meshing and chain transmission to make the rotation directions of the first hinge shafts 381 hinged to the two first limit plates 35 opposite, so that the bottoms of the first limit plates 35 move closer to or away from each other. The first transmission mechanism 382 includes a third gear fixed to the end of the other first hinge shaft 381 and a second rotating shaft rotatably arranged at the bottom of the third mounting plate 34. The side wall fixed sleeve of the second rotating shaft is provided with fourth gears arranged at intervals, one of the fourth gears is meshed with the first gear, and the other fourth gear is connected to the third gear through a chain transmission.

[0108] When the second adjustment component 39 is specifically operated, the second servo motor is started, and the output shaft of the second servo motor drives the second hinge shaft 392 to rotate through the second transmission mechanism 391, thereby driving the second limit plate 37 to rotate. The second transmission mechanism 391 includes a third rotating shaft fixedly arranged at the end of the second servo motor through a coupling and a fourth rotating shaft rotatably arranged on the side wall of the first limit plate 35. The ends of the fourth rotating shaft, the third rotating shaft and the second hinge shaft 392 are all fixedly sleeved with a fifth gear, and the fifth gears are meshed one by one, so that the second servo motor drives the second hinge shaft 392 to rotate, thereby driving the second limit plate 37 to rotate;

[0109] Since the limiting rod 36 has a certain height and the arc-shaped groove 371 is provided, it is convenient to adaptively limit the flange at the end of the transmission shaft 4, which is convenient for actually fixing the end of the transmission shaft 4 for use.

[0110] A second nozzle 6 is fixedly provided at the center of the bottom of the third mounting plate 34 to clean the transmission shaft 4 from the end of the transmission shaft 4.

[0111] Flow guiding grooves 372 are formed on both sides of the side wall of the second limiting plate 37 to limit the blockage of the second limiting plate 37 to the end of the transmission shaft 4 when the end of the transmission shaft 4 is cleaned by the second nozzle 6. Arc-shaped grooves 371 are formed on the side of the second limiting plate 37 close to each other.

[0112] The water and the like in the installation groove are discharged through the water guiding hole 302 to avoid affecting the long-term use.

[0113] The electronic devices such as the first servo motor of the present invention are all connected to an external power supply and a controller through wires for convenient actual control and use. The first nozzle 51 and the second nozzle 6 of the present invention are both connected to an external cleaning liquid pipeline for convenient actual cleaning use. These are all prior arts and will not be elaborated here.
