Description

Technical Field

[0001] The invention relates to the field of cleaning technology, in particular to an outer surface cleaning device and method for automobile transmission shaft production. Background Art

[0002] During the production process, the transmission shaft of the car will be exposed to various oils, dust and other impurities. If these impurities are not removed in time, they will affect the running accuracy of the transmission shaft, and even cause increased wear and shorten its service life. In addition, the surface of the transmission shaft is usually coated with a protective layer. If the transmission shaft is not cleaned, it is easy to affect the subsequent coating of the protective layer, thus affecting the actual use of the transmission shaft.

[0003] Publication number CN119346521A discloses a cleaning device for automobile parts production. The problem raised in its background technology is: when the current equipment uses a drum to clean automobile parts, multiple automobile parts are often placed inside a cleaning drum. When the cleaning drum drives the automobile parts to rotate, they will collide with each other and are prone to damage. At the same time, after the automobile parts are cleaned, water stains will adhere to the surface, and the staff needs to manually dry them, which increases the labor intensity of the staff.

[0004] Based on the existing technology, there are the following problems: The existing automobile transmission shaft cleaning equipment usually cleans the transmission shaft by immersing it in cleaning liquid or by spraying it. In order to reduce collisions between transmission shafts, the position of the transmission shaft is relatively fixed, which makes it difficult to expose the rotating part of the transmission shaft end and the telescopic part in the middle part, making it difficult to fully clean the shaft. There are certain shortcomings. Referring to the above application documents, it only uses partitions to place automobile parts in different positions to reduce collisions between parts. There are certain shortcomings. In order to solve the above problems, an outer surface cleaning device and method for automobile transmission shaft production are proposed. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 , an outer surface cleaning device for automobile transmission shaft 4 production, comprising a body 1, a transmission shaft 4 and a frame 2 fixed in the body 1, the frame 2 is U-shaped, and the opening of the frame 2 faces the front of the body 1, so that after the door of the body 1 is opened, the transmission shaft 4 to be cleaned is placed in the frame 2 along the opening of the frame 2, which is a prior art and will not be described in detail here, and also includes an adjustment mechanism 3 arranged at intervals at the top and bottom of the inner side of the frame 2 and used to adjust the posture of the transmission shaft 4 and a cleaning mechanism 5 arranged outside the adjustment mechanism 3 for cleaning the transmission shaft 4, and the adjustment mechanism 3 is symmetrically arranged with respect to the center point of the frame 2; See also Figure 4 , Figure 7 and Figure 8 , the cleaning mechanism 5 comprises: The first plate body 53 is lifted and disposed on the outer side of the adjustment mechanism 3. A second plate body 52 capable of moving along a circular trajectory in the first plate body 53 is sleeved on one side of the first plate body 53 that is close to each other. A first nozzle 51 is fixedly provided at the inner center of the first plate body 53 and the second plate body 52. ​​A first electromagnet 57 arranged opposite to each other is fixedly provided at the inner center of the first plate body 53. A second electromagnet 56 is fixedly provided on one side of the second plate body 52 that is close to each other, so that the second plate body 52 can move along a circular trajectory in the first plate body 53. A moving component 55 is provided inside the first plate body 53 to cooperate with the second electromagnet 56 to further drive the first plate body 53 to move. A lifting component 54 for adjusting the height of the first plate body 53 is provided on the top of the first plate body 53.

[0025] The first plate body 53 is hollow in design, and the side wall of the second plate body 52 is in contact with the inner wall of the first plate body 53 and is sealed; The first plate body 53 and the second plate body 52 are both designed to be arc-shaped, and the first plate body 53 and the second plate body 52 are connected to form a ring body, so as to clean the transmission shaft 4 along the side wall of the transmission shaft 4.

[0026] In a specific implementation, when the ends of the transmission shaft 4 are fixed by the adjustment 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 first nozzle 51 is connected to an external cleaning liquid pipeline 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 the cleaning of the transmission shaft 4 in multiple directions; Since the end of the transmission shaft 4 is connected to the telescopic part in the middle thereof by a universal joint, both ends of the telescopic part in the middle of the transmission shaft 4 can rotate to meet the actual transmission needs of the automobile. Therefore, in order to fully clean the rotating part of the transmission shaft 4, the angles of the two ends of the transmission shaft 4 are adjusted by the adjustment mechanism 3 to expose the rotating part. At this time, an external cleaning liquid pipeline is connected through the second nozzle 6 to clean the rotating parts of the two ends of the transmission shaft 4 at the top and bottom through the second nozzle 6, and cooperate with the first nozzle 51, etc. to facilitate comprehensive cleaning of the transmission shaft 4 and improve the cleaning effect.

[0027] See also Figure 7 , Figure 8 and Fig. 9 , the mobile component 55 comprises: The moving rod 554 is sleeved on the bottom inner wall of the first plate body 53. The moving rod 554 is located on one end side wall of the first plate body 53 and has a third electromagnet 557 embedded in the side facing the second electromagnet 56. 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 a gap is left between the top of the moving rod 554 and the top inner wall of the first plate body 53. The bottom of the moving rod 554 is fixedly provided with a retaining rod 552; The mounting cover 551 is fixed at the bottom of the first plate body 53, and a through groove matched with the shift rod 552 is opened at the bottom of the mounting cover 551. The cross-section of the shift rod 552 is designed as a regular hexagon to limit the displacement of the moving rod 554. The shift rod 552 is located on the side wall of one end of the mounting cover 551 and is located at the bottom of the retaining ring 553 and is sleeved with a first spring.

[0028] The mobile assembly 55 also includes: The push plate 555 is fixedly arranged on the 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 before the second plate body 52, so as to squeeze the moving rod 554 from the gap at the top of the moving rod 554. The lower end of the side of the push plate 555 close to the moving rod 554 and the top of the moving rod 554 are both designed in an arc shape, and the bottom of the push plate 555 is designed to be inclined; The limiting inclined surface 556 is provided on the side where the second plate body 52 is close to each other, and is smoothly connected to the bottom inclined part of the abutment plate 555 , so that the second plate body 52 can press the moving rod 554 after the abutment plate 555 presses the moving rod 554 .

[0029] In a specific implementation, the second plate 52 is sleeved in the first plate 53, so that a repulsive force is generated by the first electromagnet 57 and the second electromagnet 56 being close to each other, thereby driving the second plate 52 to make a circular motion in the first plate 53, thereby adjusting the position of the first nozzle 51 inside the second plate 52, so as to clean the transmission shaft 4 from multiple directions and improve the cleaning effect; In order to fit the shape of the transmission shaft 4, the first plate 53 and the second plate 52 are made annular after being connected and combined, so as to facilitate the cleaning of the transmission shaft 4 in multiple directions. In order to increase the moving distance of the arc-shaped first plate 53 in the arc-shaped second plate 52, thereby further increasing the cleaning range of the first nozzle 51 for the transmission shaft 4, a moving assembly 55 is provided. When the moving assembly 55 is specifically implemented, when the first electromagnet 57 and the second electromagnet 56 are restricted by the annular shape and cannot drive the second plate 52 to move by repulsion, one side of the second plate 52 cancels the squeezing of the moving rod 554, 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 opposite to each other, so that the second electromagnet 56 and the third electromagnet 56 can clean the transmission shaft 4. The repulsive force drives the second plate 52 to move, thereby further increasing the moving distance of the second plate 52, so as to flexibly adjust the position of the first nozzle 51 for cleaning the transmission shaft 4, thereby facilitating the cleaning of the transmission shaft 4 in multiple directions. When the squeezing of the moving rod 554 on the same side is cancelled on one side of the first plate 53, the other side of the second plate 52, through the action of the abutment plate 555, first contacts with the moving rod 554 on the other side and squeezes the moving rod 554 downward, so that the other side of the second plate 52 can squeeze the moving rod 554 on the other side to the bottom of the second plate 52 through the limiting inclined surface 556, so that the second plate 52 has enough moving space in the first plate 53, and the movement of the second plate 52 is not hindered, so as to ensure the stability of the position adjustment of the first nozzle 51.

[0030] When adjusting the position of the second plate 52 on the first plate 53, the first electromagnet 57 on one side of the first plate 53 cooperates with the second electromagnet 56 on the same side. At this time, the first electromagnet 57 and the second electromagnet 56 on the other side of the first plate 53 and the second plate 52 do not work, so that the second plate 52 can move in the first plate 53, or there is a difference in the repulsive force generated on both sides, so that the second plate 52 can make a circular motion in the first plate 53 while limiting the position of the second plate 52, thereby improving the stability of the second plate 52; The second plate 52 squeezes the moving rod 554, and in order to make the second plate 52 move smoothly to the top of the moving rod 554, the abutment plate 555 first contacts the moving rod 554, so as to squeeze the moving rod 554 from the gap at the top of the moving rod 554, and the limiting inclined surface 556 is provided, so that the second plate 52 squeezes the moving rod 554, so that the second plate 52 squeezes the moving rod 554 smoothly, and the position of the second plate 52 except the limiting inclined surface 556 is in contact with the inner wall of the first plate 53, so as to improve the stability of the movement of the second plate 52; By making the side wall of the second plate body 52 fit with the inner wall of the first plate body 53 and forming 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. By providing the mounting cover 551, the gear lever 552 moves along the mounting cover 551, and a dynamic seal design can be formed between the gear lever 552 and the mounting cover 551, thereby preventing the normal use of the first electromagnet 57 and the second electromagnet 56 from being affected. By setting the shift rod 552 to limit the vertical movement of the moving rod 554, the third electromagnet 557 is always directed toward the second electromagnet 56, thereby ensuring the stability of the use of the third electromagnet 557 and the second electromagnet 56.

[0031] See also Figure 4 , Figure 5 and Figure 6 , the lifting assembly 54 comprises: The guide rod 541 is fixedly arranged on the top of the first plate body 53. The top of the guide rod 541 extends along the third mounting plate 34, the second mounting plate 33 and the first mounting plate 32 to the top of the machine body 1. The tops of the third mounting plate 34, the second mounting plate 33 and the first mounting plate 32 are all provided with guide holes for sleeve-mounting the guide rod 541. The inner walls of the guide holes are all fixedly provided with first sliders. The back sides of the side walls of the guide rod 541 are all provided with first slide grooves 544. The first sliders are placed in the first slide grooves 544 to limit the lifting and lowering of the guide rod 541. The front sides of the side walls of the guide rod 541 are embedded with third toothed plates 542. The rotating rod 543 is rotatably arranged on the top of the third mounting plate 34. Both ends of the side walls of the rotating rod 543 are fixedly sleeved with second gears meshing with the third gear plate 542. The top of the third mounting plate 34 is fixedly provided with a third servo motor for driving the rotating rod 543 to rotate. The side wall of the connecting rod is provided with a rotating hole for installing the rotating rod 543.

[0032] In a specific implementation, the third servo motor is started, and the output shaft of the third servo motor drives the rotating rod 543 to rotate, and the rotating rod 543 drives the first plate 53 to move through the second gear and the third gear plate 542, so as to adjust the height of the first nozzle 51; The guide rod 541 is slidably connected with the first mounting plate 32 and the second mounting plate 33 to improve the stability of the vertical movement of the guide rod 541 and the first nozzle 51; The output shaft of the third servo motor is fixed with a first rotating shaft through a coupling, and the first rotating shaft and the rotating rod 543 are connected through gears and chain transmission, so that the third servo motor drives the rotating rod 543 to rotate. This is the existing technology and will not be described in detail here.

[0034] In the specific implementation, the flange hole of the flange at the end of the transmission shaft 4 is sleeved on the side wall of the limiting rod 36, and then the positions of the first limiting plate 35, the second limiting plate 37 and the limiting rod 36 are adjusted by the first adjusting component 38, the second adjusting component 39 and the third adjusting component 30 to fix the end of the transmission shaft 4, so as to facilitate the installation of the transmission shaft 4 on the inner side of the frame 2 for subsequent cleaning, and by limiting the two ends of the transmission shaft 4, the end of the transmission shaft 4 is deflected relative to the middle part of the transmission shaft 4 under the action of the universal joint of the transmission shaft 4, so as to facilitate the cleaning of the gap at the rotating position, etc., and to facilitate the fixing of the transmission shaft 4 while improving the cleaning effect; The position of the third mounting plate 34 can be adjusted conveniently by the electric push rod 31, so that it can be adjusted according to the length of the transmission shaft 4. The first adjusting assembly 38, the second adjusting assembly 39 and the third adjusting assembly 30 can cooperate to fix the transmission shaft 4 of different sizes. The second limiting plate 37 can be rotated by the second adjusting assembly 39, so that the end of the transmission shaft 4 is deflected, so that the end of the transmission shaft 4 is exposed. When the end of the transmission shaft 4 is deflected, when the degree of deflection 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 is telescoped, so that the telescopic part is exposed, further improving the comprehensiveness of cleaning. The electric push rod 31 can be used to pull the two ends of the transmission shaft 4. When the second adjusting assembly 39 cannot fully expose the telescopic part, the telescopic part is fully unfolded by pulling the two ends of the transmission shaft 4 to avoid affecting the cleaning effect. The inner wall diameter of the ring formed by the first plate body 53 and the second plate body 52 is larger than the maximum space occupied by the maximum-sized transmission shaft 4 after deflection, 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 the 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 practical use, which will not be elaborated here.

[0037] 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; 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 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; 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, and it is convenient to actually fix the end of the transmission shaft 4.
