Description

Technical Field

[0001] The present invention relates to the technical field of suspension conveyors, and more particularly to a suspension conveying mechanism for producing motor shafts. Background Art

[0002] In the motor manufacturing industry, motor shafts are core components, and their production process involves multiple complex steps, including turning, grinding, heat treatment, and surface varnishing. Material transfer between these steps significantly impacts production efficiency, product quality, and costs. With the development of intelligent manufacturing technology, suspended conveying mechanisms are increasingly being used in the production and transportation of various parts due to their advantages, such as small footprint and flexible conveying paths. However, existing suspended conveying mechanisms still have many shortcomings when used in motor shaft production:

[0003] When conveying motor shafts for paint dipping, existing conveyors can only perform single linear movement or simple rotation, making it difficult to achieve complex multi-angle and multi-mode movements. This results in uneven paint dipping across all parts of the shaft during processing, affecting the uniformity and comprehensiveness of the processing, and thus limiting product production efficiency and effectiveness.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, by setting up the suspension conveying mechanism and the paint dipping section, the conveying mechanism is suitable for the paint dipping production stage in the production process of the motor shaft. During the paint dipping process, the driving shaft is driven by the annular toothed belt. Its special gear transmission structure causes the driven shaft to produce different speeds and rotation circles, thereby driving the shaft screw and the longitudinal screw to rotate. Since a reverse torsion spring is provided at the rotating connection, the double-moving frame will produce three modes of bidirectional vibration. The vibration stroke and vibration frequency in each vibration mode are different. These three vibration modes are switched cyclically, which can make the paint liquid act on the shaft body from different angles and forces, avoiding the possible penetration dead angles of a single vibration mode, ensuring that the paint liquid can fully penetrate in all directions and positions, improving the penetration uniformity and integrity of the paint liquid, and thus improving the insulation performance and protective effect of the shaft body.

[0018] 2. The three vibration modes of the double-action frame of the present invention are cyclically switched to form a specific flow pattern for the paint liquid, fully mix the components in the paint liquid, and prevent the paint liquid from sedimentation and stratification. The good paint liquid stirring effect helps to maintain the stable performance of the paint liquid. The evenly mixed paint liquid can better adhere to the surface of the shaft body to form a higher quality paint layer. Moreover, stirring can also make the solvent in the paint liquid evaporate more evenly, reducing paint layer defects caused by uneven solvent volatilization, such as bubbles, pinholes, etc., thereby improving the quality and appearance of the paint layer. The three vibration modes of the double-action frame are cyclically switched to change the state of the shaft body when immersed in the paint liquid. Different vibration modes can reduce the possibility of bubbles generated by the paint liquid during the contact process. For bubbles that have already been generated, different vibration modes can provide different forces and directions to promote the discharge of bubbles. The bubbles are processed from multiple angles and stages, effectively reducing bubble defects in the paint layer and improving the density and quality of the paint layer.

[0019] 3. In the present invention, the driven rotary sleeve drives the longitudinal screw, reciprocating shaft, swing frame, reversing shaft and shaft screw to rotate. Combined with the reversing torsion spring, the swing frame and reversing shaft can achieve complex swinging and rotating movements. During the production and transportation process of the motor shaft, this complex movement can enable the shaft to achieve multi-angle and multi-mode rotation and swing at different processing positions, which helps to improve the uniformity and comprehensiveness of the processing and enhance the performance and quality of the product.

[0020] 4. The suspension system of the present invention drives the annular hanging belt to operate by driving the transmission main wheel through the conveying motor, and utilizes the differential gears that are meshed with each other and have different radii to make the annular toothed belt and the annular hanging belt rotate in opposite directions and at different speeds. The actual layout trajectory, height and length of the annular hanging belt and the annular toothed belt can be customized according to the actual production requirements of the motor shaft, and then combined with the central control system to control the speed of the two, so that the suspension system can be laid out at a set height and present a set transmission state in each processing section, so as to better meet the requirements of different processing sections in the production process of the motor shaft, thereby improving production efficiency and product quality.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 As shown, the present invention provides a suspension conveying mechanism for producing motor shafts, comprising a suspension system, to which a reversely rotatable annular hanging belt 1 and annular toothed belt 2 are connected, and a plurality of suspension systems are mounted on the annular hanging belt 1;

[0033] The suspension system includes a conveyor frame 20, on which two transmission main wheels 21 and two transmission sub-wheels 22 are rotatably mounted. The two transmission main wheels 21 are both transmission-connected to the annular hanging belt 1, and the two transmission sub-wheels 22 are both transmission-connected to the annular toothed belt 2. A conveying motor 23 is mounted on the conveyor frame 20, and the output shaft end of the conveying motor 23 is fixedly connected to a transmission main wheel 21. A differential gear 24 is mounted on each of the transmission main wheel 21 and the transmission sub-wheel 22. The two differential gears 24 mesh with each other, and the radii of the two differential gears 24 are different. A paint dipping processing section is fixedly provided on the conveyor frame 20, and the position of the annular toothed belt 2 corresponds to the position of the paint dipping processing section.

[0034] To ensure that the shaft body 19 can be accurately dipped in paint when passing through the dip-painting processing section;

[0035] The actual layout trajectory of the ring suspender 1, the specific height of each point of the ring suspender 1, and the length of the ring suspender 1 and the ring toothed belt 2 can be customized according to the actual production requirements of the motor shaft to ensure that the suspension system can be laid out at the set height and present the set transmission state in each processing section;

[0036] In actual production, this mechanism is equipped with a central control system, which is used to control the rotation speed of the ring hanging belt 1 and the ring toothed belt 2;

[0037] The conveying motor 23 drives the transmission main wheel 21 to drive the endless hanging belt 1 to operate. Since a transmission main wheel 21 and a transmission secondary wheel 22 are equipped with a differential gear 24 that meshes with each other and has different radii, the endless toothed belt 2 and the endless hanging belt 1 can rotate in opposite directions and at different speeds.

[0038] When the shaft body 19 is transported to the varnishing process section via the annular hanging belt 1 along with the suspension system, the annular toothed belt 2 drives the driving shaft 7 to rotate, thereby driving a series of subsequent transmissions to ensure that the shaft body 19 can be accurately dipped in paint when passing through the varnishing process section;

[0039] The actual layout trajectory and height of the endless suspender 1, as well as the lengths of the endless suspender 1 and the endless toothed belt 2, can be customized according to the actual production requirements of the motor shaft. Combined with the central control system to control the rotational speeds of the endless suspender 1 and the endless toothed belt 2, the suspension system can be laid out at a set height and present a set transmission state in each processing section, thereby improving the flexibility and adaptability of the conveying mechanism and solving the problem that existing conveying mechanisms are difficult to accurately adjust according to different production requirements. Compared with existing technologies, it can better meet the requirements of different processing sections in the motor shaft production process, thereby improving production efficiency and product quality.

[0040] The suspension system includes a single-acting frame 3, a double-acting frame 4, and a carrier 5 connected to an annular hanging belt 1. A shaft screw 6, a driving shaft 7, and a driven shaft 8 are rotatably mounted on the carrier 5. The driving shaft 7 is driven by an annular toothed belt 2.

[0041] A driven gear 25 is fixedly mounted on the driving shaft 7 and meshes with the annular toothed belt 2;

[0042] A main rotary sleeve 9 linked to the driving shaft 7 and a driven rotary sleeve 10 linked to the driven shaft 8 are rotatably mounted on the single-moving frame 3;

[0043] A first coupling groove with openings at both ends and slidingly connected to the driving shaft 7 is fixedly formed inside the main rotary sleeve 9, and a second coupling groove with openings at both ends and slidingly connected to the driven shaft 8 is fixedly formed inside the driven rotary sleeve 10. The cross-sections of the first coupling groove, the second coupling groove, the driving shaft 7, and the driven shaft 8 are all regular hexagons.

[0044] Three staggered sector gears 11 with the same radius are installed on the main rotary sleeve 9. The three sector gears 11 have different heights in the axial direction of the driving shaft 7.

[0045] There is a toothless area on the driving shaft 7 and between the two sector gears 11. The central angle between the toothless area and the toothed meshing section on the sector gear 11 is 60 degrees.

[0046] A driven gear 12 is mounted on the driven shaft 8 at positions corresponding to the three sector gears 11. The three driven gears 12 are meshed with the three sector gears 11, respectively. The three driven gears 12 have the same radius and different numbers of teeth.

[0047] The radius of the sector gear 11 is 14 times the radius of the driven gear 12. The three sector gears 11 have the same number of teeth. The gear ratio of the three driven gears 12 is 1:2:3. The number of teeth of the three driven gears 12 is a multiple of 6.

[0048] The driving shaft 7 is driven by the annular toothed belt 2, and the driven gear 25 thereon meshes with the annular toothed belt 2 to transmit power to the driving shaft 7. The main rotary sleeve 9 and the driven rotary sleeve 10 are respectively slidably connected to the driving shaft 7 and the driven shaft 8 through the first and second coupling grooves of the regular hexagon, which can not only achieve linkage but also ensure a certain degree of sliding freedom. The three staggered fan gears 11 with the same radius on the main rotary sleeve 9, when the driving shaft 7 rotates, due to the toothless area with a central angle of 60° between the corresponding two fan gears 11 on the driving shaft 7, the fan gears 11 intermittently mesh with the driven gear 12 on the driven shaft 8. The three driven gears 12 have the same radius but different numbers of teeth, and the radius of the fan gear 11 is 14 times the radius of the driven gear 12. This special gear transmission structure enables the driven shaft 8 to produce different speeds and rotational circles.

[0049] The driven shaft 8 rotates the axial screw 6 via a toothed belt, and simultaneously drives the longitudinal screw 13 via transmission components such as the belt shaft 41 and the elastic synchronous belt 26. The longitudinal screw 13 is in transmission connection with the double-moving frame 4. As the speed and number of rotations of the driven shaft 8 change, the rotational states of the axial screw 6 and the longitudinal screw 13 also change accordingly. Because reversing torsion springs 17 are installed at the rotational connections between the longitudinal screw 13 and the single-moving frame 3, the rotational connections between the axial screw 6 and the carrier 5, and the rotational connections between the reciprocating shaft 14 and the double-moving frame 4, these reversing torsion springs 17 store and release energy when the rotational states change, causing the double-moving frame 4 to produce three modes of bidirectional vibration.

[0050] The vibration stroke and vibration frequency in each vibration mode are different;

[0051] The reverse torsion spring 17 is made of high carbon steel;

[0052] In the first vibration mode, the double-action frame 4 vibrates bidirectionally at a specific vibration stroke and frequency. This vibration causes the shaft body 19 to shake accordingly in the paint dipping tank, prompting the paint liquid to penetrate into the tiny gaps and holes of the shaft body 19 more quickly. In the second and third vibration modes, due to the different vibration strokes and frequencies, different impact forces and disturbance forces are generated, further enhancing the penetration ability of the paint liquid, allowing the paint liquid to reach some areas that are difficult to reach in the first vibration mode. The three vibration modes are switched cyclically, allowing the paint liquid to penetrate the shaft body 19 under different vibration environments. Different vibration modes can act on the paint liquid and the shaft body 19 from different angles and forces, avoiding the possible penetration dead angles that may exist in a single vibration mode. This cyclic switching method can ensure that the paint liquid can fully penetrate in all directions and all parts, improve the penetration uniformity and integrity of the paint liquid, and thus enhance the insulation performance and protective effect of the shaft body 19.

[0053] In the three vibration modes, the specific vibration stroke and frequency will cause the paint liquid to form a specific flow pattern, fully mixing the components in the paint liquid and preventing the paint liquid from settling and stratification. The good paint liquid stirring effect helps to maintain the stability of the paint liquid performance. The evenly mixed paint liquid can better adhere to the surface of the shaft body 19, forming a higher quality paint layer. In addition, stirring can also make the solvent in the paint liquid evaporate more evenly, reducing paint layer defects caused by uneven solvent evaporation, such as bubbles and pinholes, thereby improving the quality and appearance of the paint layer.

[0054] The cyclic switching of the three vibration modes of the double-action frame 4 can change the state of the rotating shaft body 19 when immersed in the paint liquid. Under different vibration modes, the contact mode and speed of the rotating shaft body 19 and the paint liquid are different, which can reduce the possibility of bubbles generated in the paint liquid during the contact process. For bubbles already generated in the paint liquid, different vibration modes can provide different forces and directions to promote the discharge of bubbles. The first vibration mode may cause bubbles to rise in the paint liquid, the second vibration mode can bring bubbles to the surface by changing the flow direction of the paint liquid, and the third vibration mode can further accelerate the rupture and discharge of bubbles. The cyclic switching of vibration modes can treat bubbles from multiple angles and stages, effectively reducing bubble defects in the paint layer and improving the density and quality of the paint layer.

[0055] The cyclic switching of the three vibration modes enables the shaft body 19 to more quickly and fully contact the paint liquid during the paint dipping process. The different vibration modes can accelerate the flow rate of the paint liquid on the shaft surface and shorten the time it takes for the paint liquid to cover the entire shaft body 19. Since the penetration, stirring and bubble discharge effects of the paint liquid are all improved, the residence time of the shaft body 19 in the paint dipping tank can be correspondingly reduced. Under the premise of ensuring the quality of the paint layer, reducing the paint dipping time can improve the efficiency of the entire production process and reduce production costs.

[0056] The cyclic switching of the three vibration modes can be adaptively optimized for different rotating shafts, thereby enabling the device to perform universal varnishing processing on rotating shaft bodies 19 of multiple specifications;

[0057] A longitudinal screw 13 is rotatably mounted on the single-moving frame 3, and the longitudinal screw 13 is transmission-connected to the double-moving frame 4. A reciprocating shaft 14 and a swing frame 15 are rotatably mounted on the double-moving frame 4, and a reversing shaft 16 is rotatably mounted on the swing frame 15. The reciprocating shaft 14, the swing frame 15, the reversing shaft 16, the longitudinal screw 13, and the shaft screw 6 are all driven by a driven rotary sleeve 10.

[0058] A transmission toothed belt is connected between the shaft screw 6 and the driven shaft 8. A belt shaft 41 is rotatably mounted on the single movable frame 3. First bevel gears are mounted on the belt shaft 41 and the longitudinal screw 13. The two first bevel gears are orthogonally meshed.

[0059] An elastic synchronous belt 26 is installed on the belt shaft 41. The driven rotary sleeve 10, the reciprocating shaft 14 and the belt shaft 41 are all connected to the elastic synchronous belt 26. The elastic synchronous belt 26 is made of rubber. The inner wall of the elastic synchronous belt 26 is evenly covered with friction lines. The elastic synchronous belt 26 can elastically compensate for the displacement of the double-moving frame 4.

[0060] When the double-moving frame 4 is displaced, the elastic synchronous belt 26 absorbs and releases energy through its own elastic deformation, thereby elastically compensating for the displacement of the double-moving frame 4 and ensuring the stability of the transmission;

[0061] A toothless bevel gear 27 is installed at the bottom end of the reciprocating shaft 14, and a second bevel gear is installed on the swing frame 15 and the reversing shaft 16. The two second bevel gears are adapted to be connected with the toothless bevel gear 27. The two second bevel gears are respectively arranged on both sides of the toothless bevel gear 27. The center angle corresponding to the tooth meshing section on the toothless bevel gear 27 is 90°. The radius of the second bevel gear is twice the radius of the toothless bevel gear 27. A top shaft 28 is rotatably installed on the swing frame 15. A third bevel gear is installed on the top shaft 28 and the reversing shaft 16. The two third bevel gears are orthogonally meshed.

[0062] The rotational connection between the longitudinal screw 13 and the single-action frame 3, the rotational connection between the axial screw 6 and the carrier 5, and the rotational connection between the reciprocating shaft 14 and the double-action frame 4 are all provided with a reverse torsion spring 17;

[0063] The driven rotary sleeve 10 drives the longitudinal screw 13, the reciprocating shaft 14, the swing frame 15, the reversing shaft 16 and the shaft screw 6 to rotate. The shaft screw 6 and the driven shaft 8 are driven by a toothed belt. The belt shaft 41 and the longitudinal screw 13 are orthogonally meshed through the first bevel gear. The driven rotary sleeve 10, the reciprocating shaft 14 and the belt shaft 41 are driven by an elastic synchronous belt 26. The elastic synchronous belt 26 is made of rubber and has friction lines on the inner wall. It can elastically compensate for the displacement of the double-moving frame 4 to ensure the stability of the transmission. The toothless bevel gear 27 at the bottom end of the reciprocating shaft 14 is adapted to be connected with the second bevel gear on the swing frame 15 and the reversing shaft 16. The center angle of the tooth meshing section on the toothless bevel gear 27 is 90°, and the radius of the second bevel gear is 2 times the radius of the toothless bevel gear 27. times, the top shaft 28 on the swing frame 15 and the reversing shaft 16 are orthogonally meshed through the third bevel gear, and combined with the reversing torsion spring 17 at the rotation connection between the longitudinal screw 13 and the single-action frame 3, the axial screw 6 and the carrier 5, and the reciprocating shaft 14 and the double-action frame 4, the swing frame 15 and the reversing shaft 16 can realize complex swinging and rotating movements. During the production and transportation process of the motor shaft, this complex movement can enable the shaft to realize multi-angle and multi-mode rotation and swing at different processing positions, which helps to improve the uniformity and comprehensiveness of the processing, solves the problem of the single movement mode of the shaft in the existing conveying mechanism during the conveying process, and compared with the existing technology, it can enable the shaft to be more fully processed in the production process, thereby improving the performance and quality of the product;

[0064] The bottom surface of the swing frame 15 is connected with a hanging bracket 18;

[0065] A lock pin 29 is slidably mounted on the swing frame 15, and a handle is fixedly mounted on the lock pin 29. The handle is used to drive the lock pin 29 to move quickly. A set of tension springs 30 is installed between the lock pin 29 and the swing frame 15. Two pin holes are provided on the top surface of the hanging bracket 18, and both pin holes are adapted to connect with the lock pin 29.

[0066] The bottom surface of the swing frame 15 is connected to the pin hole of the top surface of the hanger 18 by the lock pin 29, and a tension spring 30 is installed between the lock pin 29 and the swing frame 15. During normal operation, the lock pin 29 is firmly inserted into the pin hole under the action of the tension spring 30, ensuring the stability of the connection between the hanger 18 and the swing frame 15, so that the rotating drive system installed on the hanger 18 can accurately move with the movement of the swing frame 15. When it is necessary to replace the hanger 18 or maintain the hanger 18, the lock pin 29 can be pulled out by overcoming the tension of the tension spring 30, and the hanger 18 and the swing frame 15 can be easily separated. During the production of the motor shaft, this connection method that can be easily disassembled and installed is convenient for the inspection and replacement of the hanger 18 and the rotating drive system thereon, thereby improving the maintenance efficiency of the equipment and solving the problem that the connection method of the hanger 18 and the swing frame 15 in the existing conveying mechanism is difficult to disassemble and maintain. Compared with the existing technology, it reduces the equipment maintenance time and improves the continuity of production.

[0067] A rotation drive system linked to the reversing shaft 16 is installed on the hanger 18 . A plurality of rotating shaft bodies 19 are installed on the rotation drive system and the rotating shaft bodies 19 are driven to rotate back and forth and to revolve.

[0068] The rotary drive system includes a revolution shaft 31 rotatably connected to the hanger 18. A spin shaft 32 is rotatably mounted on the inner wall of the revolution shaft 31. The top end of the spin shaft 32 and the bottom end of the top shaft 28 are both mounted with transmission pads. The transmission pads are made of rubber and have friction patterns on their surfaces.

[0069] A coupling shaft 33 is rotatably mounted on the bracket 18, a linkage bevel gear is mounted on the coupling shaft 33, and fourth bevel gears are mounted on both the spin shaft 32 and the revolution shaft 31. Both fourth bevel gears are transmission-connected to the linkage bevel gears, and the two fourth bevel gears are respectively arranged on both sides of the linkage bevel gears.

[0070] A chuck 34 is sleeved on the revolving shaft 31, and two guide grooves are provided on the revolving shaft 31. A guide block slidably connected to the guide groove is installed on the inner wall of the chuck 34 and at the position corresponding to each guide groove. A compression spring 35 limited by the revolving shaft 31 is installed on the top surface of the chuck 34. A bracket 36 is installed on the revolving shaft 31, and a group of clamping modules are installed between the bracket 36 and the chuck 34. An active ring gear 37 is installed at the bottom end of the spin shaft 32.

[0071] Each clamping module includes an active clamping seat 38 and a driven clamping seat 39 . The active clamping seat 38 is rotatably mounted on the bracket 36 . A bottom gear 40 meshing with the active ring gear 37 is mounted on the active clamping seat 38 . The driven clamping seat 39 is rotatably mounted on the chuck 34 .

[0072] When the reversing shaft 16 rotates, the power is transmitted to the spin shaft 32 through the transmission pad, and the spin shaft 32 drives the active ring gear 37 to rotate. The active ring gear 37 meshes with the bottom gear 40 on the active clamping seat 38, so that the active clamping seat 38 rotates. At the same time, the linkage bevel gear on the coupling 33 is connected with the spin shaft 32 and the fourth bevel gear on the revolving shaft 31, driving the revolving shaft 31 to rotate. The clamping plate 34 on the revolving shaft 31 cooperates with the bracket 36 under the action of the compression spring 35, and clamps the shaft body 19 through the clamping module, so that the rotation of the spin shaft 32 The shaft body 19 is caused to spin, and the rotation of the revolution shaft 31 causes the shaft body 19 to revolve. During the production process of the motor shaft, the rotation drive system drives the shaft body 19 to spin and reciprocate, so that all parts of the shaft can be processed evenly during the processing. For example, in the paint dipping process, the paint liquid can be more evenly adhered to the surface of the shaft, which solves the problem that the existing conveying mechanism is difficult to make the shaft realize complex rotational motion during the conveying process to ensure processing uniformity. Compared with the existing technology, the processing quality and performance of the motor shaft are improved.

[0073] The working principle and use process of the present invention:

[0074] The conveying motor 23 is started, and its output shaft drives the transmission main wheel 21 fixedly connected to it to rotate. Since the transmission main wheel 21 is in transmission connection with the endless suspender 1, the endless suspender 1 is driven to operate. At the same time, the transmission secondary wheel 22, which is meshed with the transmission main wheel 21 through the differential gear 24, drives the endless toothed belt 2 to rotate in the opposite direction. The two have different speeds due to the different radii of the differential gear 24. The suspension system suspended on the endless suspender 1 moves with the endless suspender 1. When it reaches the varnishing process section, since the position of the endless toothed belt 2 corresponds to the varnishing process section, the endless toothed belt 2 drives the driven gear 25 on the driving shaft 7, causing the driving shaft 7 to rotate.

[0075] The rotation of the driving shaft 7 drives the main rotating sleeve 9, which is slidingly connected to it via a regular hexagonal first coupling groove, to rotate. The three staggered sector gears 11 on the main rotating sleeve 9 and having the same radius rotate accordingly. Because there is a toothless area with a central angle of 60° between the corresponding two sector gears 11 on the driving shaft 7, the sector gears 11 intermittently mesh with the driven gears 12 on the driven shaft 8. The three driven gears 12 have the same radius but a gear ratio of 1:2:3, which causes the driven shaft 8 to produce different speeds and rotations.

[0076] The driven shaft 8 drives the shaft screw 6 to rotate through the transmission toothed belt, and at the same time drives the longitudinal screw 13 to rotate through the belt shaft 41, elastic synchronous belt 26 and other transmission components. The longitudinal screw 13 is connected to the double-moving frame 4. The driven shaft 8 also drives the reciprocating shaft 14, the swing frame 15, and the reversing shaft 16 to rotate through the driven rotary sleeve 10. The reversing torsion spring 17 at the rotation connection between the longitudinal screw 13 and the single-moving frame 3, the shaft screw 6 and the carrier 5, and the reciprocating shaft 14 and the double-moving frame 4 stores and releases energy when the rotation state changes, so that the double-moving frame 4 produces three irregular bidirectional vibration modes with different vibration strokes and frequencies. The three vibration modes are cyclically switched.

[0077] The bottom surface of the swing frame 15 is connected with the pin hole on the top surface of the hanger 18 through the lock pin 29. When the reversing shaft 16 rotates, the power is transmitted to the spin shaft 32 through the transmission pad. The spin shaft 32 drives the active ring gear 37 to rotate. The active ring gear 37 engages with the bottom gear 40 on the active clamping seat 38, so that the active clamping seat 38 rotates. At the same time, the linkage bevel gear on the coupling 33 is connected with the spin shaft 32 and the fourth bevel gear on the revolving shaft 31, driving the revolving shaft 31 to rotate. The clamping plate 34 on the revolving shaft 31 cooperates with the bracket 36 under the action of the compression spring 35, and the shaft body is clamped by the clamping module. 19 is clamped, the rotation of the spin axis 32 causes the shaft body 19 to spin, and the rotation of the revolution axis 31 causes the shaft body 19 to revolve. In the paint dipping process, the reciprocating rotation and revolution of the shaft body 19, combined with the vibration of the double-moving frame 4, make the paint liquid evenly adhere to the surface of the shaft, completing the paint dipping operation. During the whole process, the speed of the annular hanging belt 1 and the annular toothed belt 2 is controlled by the central control system, and the actual layout trajectory, height and length of the annular hanging belt 1 and the annular toothed belt 2 can be customized according to the actual production requirements of the motor shaft to meet the requirements of different processing sections;
