An intelligent pickling device and method based on transmission shaft assembly processing

Abstract

This invention relates to the field of drive shaft processing technology, specifically disclosing an intelligent pickling device and method based on drive shaft assembly processing. It includes an auxiliary mechanism capable of entering and exiting the pickling tank. The invention utilizes a first hooking assembly and a second hooking assembly with a second vertical rod and a bent rod that move within a flange hole, thereby reducing areas on the flange hole inner wall that are not in contact with the pickling solution. This reduces the probability of pickling dead zones at the fixed drive shaft assembly location, improving the overall thoroughness of the pickling process. When the first vertical rod of the first hooking assembly rotates, it drives the bent rod, the second vertical rod, and the drive shaft assembly to rotate, facilitating contact between complex parts of the drive shaft assembly and the pickling solution. Furthermore, the bent rod can pull the drive shaft assembly from one end, exposing the extension and retraction parts of the drive shaft assembly and allowing them to contact the pickling solution, thus improving the overall thoroughness of the pickling process.

Description

Technical Field

[0001] This invention relates to the field of transmission shaft processing technology, specifically to an intelligent pickling device and method based on the processing of transmission shaft assemblies. Background Technology

[0002] During the processing of the drive shaft assembly, the chemical reaction generated by pickling removes oxide scale, rust, residual oil and welding slag from the surface of the drive shaft assembly, resulting in a clean metal substrate. This provides a high-quality foundation for subsequent painting, electroplating and other processes, significantly improves coating adhesion, and avoids coating peeling problems in the later stages.

[0003] Patent application CN204401109U discloses an automotive drive shaft pickling device, which is designed to facilitate the filtration of pickling solution, with the filtered pickling solution flowing into the pickling tank, and to facilitate the pickling of the automotive drive shaft during rotation.

[0004] Based on existing technologies, the following problems exist: The drive shaft assembly has complex irregular structures such as journals, splines, and grooves. "Air pockets" can easily form in some dead corners, hindering acid flow. Furthermore, if the workpiece has localized warping or deformation, certain areas may not be fully immersed in the acid, resulting in insufficient pickling and inadequate contact with the pickling solution. This leads to residual oxide scale on the workpiece surface, affecting the quality of subsequent processing. Referring to the aforementioned application documents, they only allow for rotating the drive shaft for pickling one by one, reducing pickling efficiency and hindering contact between the surface of the drive shaft's extension and retraction parts and the pickling solution, thus limiting the thorough pickling of the drive shaft. To address these issues, an intelligent pickling device and method based on the processing of drive shaft assemblies is proposed. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent pickling device based on the processing of drive shaft assemblies, comprising a pickling tank and an auxiliary mechanism for entering and exiting the pickling tank, for batch placement of drive shaft assemblies, the auxiliary mechanism comprising: A first plate body, a second plate body is provided at the bottom of the first plate body, and a third plate body is provided at the bottom of the second plate body. There is a gap between the first plate body, the second plate body and the third plate body. After the bottom of the third plate body contacts the bottom of the inner wall of the pickling tank, the first plate body is always located at the top of the pickling tank.

The first hooking assembly includes: The first vertical rod is rotatably mounted on the side of the second plate close to the third plate. A bent rod is fixedly mounted at the bottom of the first vertical rod, and a second vertical rod is fixedly mounted at the end of the bent rod away from the first vertical rod.

[0006] Furthermore, a gap is left on the side of the first and second vertical rods that are close to each other for mounting the drive shaft assembly.

There is space between adjacent first vertical bars for the second vertical bar and the bent bar to rotate. The first and second hooking components have the same structure to limit the movement of the drive shaft assembly from both ends.

[0007] Furthermore, each of the first vertical rods is equipped with a rotating assembly at its top, and the first plate is equipped with a transmission assembly at its top. The transmission assembly and the rotating assembly work together to drive the first vertical rod to rotate without affecting its vertical movement with the second plate.

The side wall of the rotating rod is provided with a first sliding groove arranged in a ring array. The first sliding groove is provided with a first slider. The top of the first plate and the second plate are provided with a first through hole for fitting the rotating rod.

[0008] Furthermore, the rotating assembly also includes: The rotating sleeve is rotatably located at the top of the first plate. The first slider is fixedly connected to the inner wall of the rotating sleeve so that the rotating rod can move along the inner wall of the rotating sleeve. The first gear is fixedly sleeved on the outer wall of the rotating sleeve to drive the rotating sleeve and the rotating rod to rotate.

[0009] Furthermore, the transmission assembly includes: A first gear ring is rotatably mounted on the top of a first plate. A second plate is rotatably mounted on the top of the first plate. The first and second plates are coaxially designed. A first rotating rod and a second rotating rod are rotatably mounted on the top of the first plate. A second gear and a third gear are fixedly sleeved on the side wall of the first rotating rod. A fourth gear and a fifth gear are fixedly sleeved on the side wall of the second rotating rod. The second gear meshes with the first gear ring, the fourth gear meshes with the second gear ring, and the third and fifth gears are connected by a chain drive. The first servo motor is fixedly mounted on the side wall of the first plate. The output shaft of the first servo motor is fixedly mounted with a third rotating rod through a coupling. The third rotating rod is rotatably connected to the side wall of the first plate. A sixth gear is fixedly mounted on the side wall of the third rotating rod. The sixth gear meshes with the side of the second gear away from the first gear ring.

[0010] Furthermore, the transmission assembly also includes: The second slide groove is opened at the top of the first plate. The second slide groove contains a second slider, and the top of the second slider is fixedly connected to the bottom of the first gear ring. The third slide is located on the top of the first plate. The third slider is placed inside the third slide. The top of the third slider is fixedly connected to the bottom of the second gear ring. The second slide, the third slide, the second slider, and the third slider are all designed in a ring shape so that the first gear ring and the second gear ring are rotatably connected to the first plate.

[0011] Furthermore, the connection component includes: A connecting sleeve is fixedly installed at the bottom of the first plate. The outer wall of the connecting sleeve penetrates the second plate. The bottom of the connecting sleeve is fixedly connected to the top of the third plate. A second through hole for fitting the connecting sleeve is provided at the top of the second plate. The movable through slots are formed on the outer wall of the connecting sleeve and arranged in a ring array. The inner wall of each movable through slot is fitted with a movable block, and the side of the movable block that is far apart from each other is fixedly connected to the inner wall of the second plate.

[0012] Furthermore, the connection component also includes: The second servo motor is fixedly mounted on the top of the first plate. The output shaft of the second servo motor is fixedly provided with a threaded rod extending into the connecting sleeve through a coupling. The bottom of the threaded rod is rotatably connected to the top of the third plate. A threaded tube is threaded to the side wall of a threaded rod, and the outer wall of the threaded tube is fixedly connected to the side of the moving block that is close to it.

[0013] Furthermore, the hoisting assembly includes: The first hanger is fixed to the side wall of the first plate and arranged in a circular array. The top of each first hanger is fixed with a second hanger. The second hanger is designed to be inclined and has a hook fixed to its top. The top of the first hanger is located above the rotating rod, so that there is space between the first plate and the second hanger for the rotating rod and the first vertical rod to move upward.

[0014] This invention also provides a method for using an intelligent pickling device based on the processing of a drive shaft assembly. The method, employing the aforementioned intelligent pickling device based on the processing of a drive shaft assembly, includes the following steps: S1: The drive shaft assembly is positioned between the second plate and the third plate by limiting the first and second mounting components from both ends. S2: After the drive shaft assembly is installed, transfer the drive shaft assembly, the second plate and the third plate to the pickling tank and immerse them in the pickling solution in the pickling tank to pickle the drive shaft assembly. S3: During the pickling process of the drive shaft assembly, the drive shaft assembly is stretched and rotated so that the pickling solution comes into contact with the entire surface of the drive shaft assembly.

[0015] This invention provides an intelligent pickling device and method based on the processing of drive shaft assemblies. Compared with the prior art, it has the following advantages: 1. The present invention uses the second vertical rod and the bent rod of the first and second connecting components to move within the flange hole, thereby reducing the area where the inner wall of the flange hole cannot contact the pickling solution, thus reducing the probability of pickling dead corners appearing at the fixed drive shaft assembly and improving the comprehensiveness of pickling.

[0016] When the first vertical rod of the first mounting assembly is rotated, the bent rod, the second vertical rod, and the drive shaft assembly can be rotated, which facilitates the contact of complex parts of the drive shaft assembly with the pickling solution. Moreover, the bent rod can pull the drive shaft assembly from one end, exposing the extension and retraction parts of the drive shaft assembly and allowing them to contact the pickling solution, thereby improving the overall pickling process.

[0017] 2. This invention, by aligning the first and second mounting components arranged in a circular array vertically, facilitates the assembly and disassembly of the drive shaft assembly without affecting its stretching and rotation, thus improving the pickling effect. Furthermore, it facilitates batch pickling of the drive shaft assemblies and enables multiple drive shaft assemblies to rotate and stretch synchronously, thereby improving pickling efficiency.

[0018] 3. By placing electronic components such as the first servo motor and the second servo motor on the top of the first plate, the present invention reduces contact with pickling solution, making it more suitable for pickling environments and reducing damage to electronic components, facilitating long-term use. In addition, it can facilitate the simultaneous pickling of multiple drive shaft assemblies for batch pickling, thereby improving pickling efficiency. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-5A smart pickling device based on the processing of drive shaft assemblies includes a pickling tank 1 containing an oil-based pickling solution for pickling the drive shaft assemblies. It also includes an auxiliary mechanism 2 capable of entering and exiting the pickling tank 1 for batch placement of drive shaft assemblies. The auxiliary mechanism 2 includes: A first plate 25, a second plate 29 at the bottom of the first plate 25, and a third plate 21 at the bottom of the second plate 29, with a gap between the first plate 25, the second plate 29 and the third plate 21, and the first plate 25 always being located at the top of the pickling tank 1 after the bottom of the third plate 21 contacts the bottom of the inner wall of the pickling tank 1. The top of the first plate 25 is provided with a connecting component 23 for connecting the first plate 25, the second plate 29 and the third plate 21, and the height of the second plate 29 can be adjusted. The tops of the second plate 29 and the third plate 21 are both provided with a ring array of guide holes 291. A hoisting assembly 26 is disposed on the side wall of the first plate 25. A first hooking assembly 24 and a second hooking assembly 22 are respectively disposed on the side of the second plate 29 and the third plate 21 that are close to each other. The first hooking assembly 24 and the second hooking assembly 22 are arranged facing each other and aligned vertically. Both the first hooking assembly 24 and the second hooking assembly 22 are arranged in a circular array. The first hooking assembly 24 includes: The first vertical rod 241 is rotatably mounted on the side of the second plate 29 near the third plate 21. A bent rod 242 is fixedly mounted at the bottom of the first vertical rod 241, and a second vertical rod 243 is fixedly mounted at the end of the bent rod 242 away from the first vertical rod 241.

[0023] When this invention is implemented, the second servo motor 232 is started, which drives the threaded rod 233 to rotate. The threaded rod 233 drives the threaded tube 234 to move under the limit of the moving block 235 and the moving through groove 236, so that the second plate 29 moves down and gets closer to the third plate 21, reducing the distance between the first hook assembly 24 and the second hook assembly 22, so that the distance between the second vertical rods 243 of the first hook assembly 24 and the second hook assembly 22 is less than the length of the transmission shaft assembly.

[0024] After adjusting the spacing between the second vertical rods 243 of the first coupling assembly 24 and the second coupling assembly 22, the flange hole of the flange at one end of the drive shaft assembly is fitted onto the second vertical rod 243 of the first coupling assembly 24, and the flange hole at the other end of the drive shaft assembly is fitted onto the second vertical rod 243 of the second coupling assembly 22, so as to limit the drive shaft assembly from both ends.

[0025] After the drive shaft assemblies are installed on both the first mounting assembly 24 and the second mounting assembly 22, the second plate 29 is moved upward so that the flanges at both ends of the drive shaft assembly abut against the inner side of the bent rod 242. At this time, the distance between the second vertical rods 243 of the first mounting assembly 24 and the second mounting assembly 22 is insufficient to allow the drive shaft assembly to fall off, thus limiting the drive shaft assembly from falling between the first mounting assembly 24 and the second mounting assembly 22. Multiple drive shaft assemblies can be installed in batches without contact between adjacent drive shaft assemblies, facilitating sufficient contact between the pickling solution and the surface of the drive shaft assembly. Furthermore, this ensures the stability of the drive shaft assembly during transfer. Subsequently, by connecting an external hoisting device to the hook 263, the auxiliary mechanism 2 can be lifted as a whole, transferring the drive shaft assembly into the pickling tank 1. Both the second plate 29 and the first plate 25 are immersed in the pickling solution, allowing the surface of the drive shaft assembly to contact the pickling solution, thereby pickling the drive shaft assembly and removing dirt from its surface.

[0026] Because the drive shaft assembly has complex irregular structures such as journals, splines, and grooves, "air pockets" can easily form in some dead corners, hindering the flow of acid. To address this, the second servo motor 232 first moves the second plate 29 upwards, thereby moving the first mounting assembly 24 upwards to pull the drive shaft assembly from one end, exposing the telescopic parts of the drive shaft assembly for contact with the pickling solution, thus facilitating comprehensive pickling of the drive shaft assembly. Furthermore, the first servo motor 274 drives the first gear ring 271 and the second gear ring 278 to rotate, which in turn drives multiple first gears 284 and rotating rods 281 to rotate, simultaneously driving the multiple first mounting assemblies 24 arranged in a ring array to rotate. This causes the drive shaft assembly, the first mounting assemblies 24, and the second mounting assemblies 22 to rotate, facilitating the entry of pickling solution into the complex parts of the drive shaft assembly and further improving the comprehensiveness of the pickling process.

[0027] After pickling is completed, the auxiliary mechanism 2 is lifted as a whole by external hoisting equipment. During the lifting process, the pickling solution flows into the pickling tank 1 along the inner wall of the guide hole 291 and the side wall of the first plate 25. A small amount of pickling solution remaining on the surface of the auxiliary mechanism 2 is removed by subsequent cleaning steps. During cleaning, the extension and retraction parts and complex parts of the drive shaft assembly can be cleaned by the above steps to improve the cleaning effect.

[0028] The external hoisting equipment is used to hoist the auxiliary mechanism 2. The hook 263 of the external hoisting equipment is connected to the hook 263 in this application and can drive the auxiliary mechanism 2 in this application to move as a whole. The hoisting equipment is prior art and will not be described in detail here.

[0029] Please see Figure 2 The hoisting assembly 26 includes: The first lifting rod 261 is fixedly installed on the side wall of the first plate 25 and arranged in a circular array. The top of the first lifting rod 261 is fixedly provided with a second lifting rod 262. The second lifting rod 262 is designed to be inclined. The top of the second lifting rod 262 is fixedly provided with a hook 263. The top of the first lifting rod 261 is located above the rotating rod 281, so that there is space between the first plate 25 and the second lifting rod 262 for the rotating rod 281 and the first vertical rod 241 to move upward.

[0030] In practical implementation, the hook 263 of the external hoisting equipment is connected to the hook 263 of the hoisting assembly 26 in this application to facilitate the overall transfer of the auxiliary mechanism 2. By positioning the top of the first lifting rod 261 above the rotating rod 281, space is left between the first plate 25 and the second lifting rod 262 for the rotating rod 281 and the first vertical rod 241 to move upward, thus avoiding any obstruction to movement.

[0031] The first vertical rod 241 and the second vertical rod 243 have a gap on the side that are close to each other for mounting the drive shaft assembly. The height of the first vertical rod 241 is higher than that of the second vertical rod 243, and the top of the second vertical rod 243 is designed in the shape of a frustum. There is space between adjacent first vertical bars 241 for the second vertical bar 243 and the bent bar 242 to rotate. The first hook assembly 24 and the second hook assembly 22 have the same structure, so as to limit them from both ends of the drive shaft assembly respectively.

[0032] In specific implementation, by leaving a gap on the side of the first vertical rod 241 and the second vertical rod 243 that are close to each other for mounting the drive shaft assembly, it is convenient to place the flange of the drive shaft assembly between the first vertical rod 241 and the second vertical rod 243, which facilitates the limiting of the drive shaft flange. By making the height of the first vertical rod 241 higher than that of the second vertical rod 243, it is convenient to connect the first vertical rod 241 to the rotating rod 281, and it is convenient to fit the flange hole of the flange at the end of the drive shaft assembly onto the second vertical rod 243 along the top of the second vertical rod 243 to limit the driving shaft flange. By making the top of the second vertical rod 243 into a frustum shape, it is convenient to insert it into the flange hole.

[0033] By leaving space between adjacent first vertical rods 241 for the second vertical rod 243 and the bent rod 242 to rotate, movement obstacles are avoided when rotating the drive shaft assembly later, and the surface of the drive shaft assembly is made easier to contact with the pickling solution, thus improving the comprehensiveness of pickling. The first hook assembly 24 and the second hook assembly 22 have the same structure, which limits the drive shaft assembly from both ends, making it easier to limit the drive shaft assembly. The first vertical rod 241 of the second hook assembly 22 is rotatably connected to the third plate 21, thus making it easier for the second hook assembly 22 to rotate with the entire drive shaft assembly.

[0034] By aligning the first and second hooking components 24 and 22 arranged in a circular array vertically, the drive shaft assembly is hooked onto the inner side of the bent rod 242 from both ends, facilitating the assembly and disassembly. The second vertical rod 243 and the bent rod 242 are fitted into the flange holes of the drive shaft assembly. When the drive shaft assembly rotates subsequently, the second vertical rod 243 and the bent rod 242 move within the flange holes, reducing the area where the flange hole's inner wall cannot contact the pickling solution. This reduces the probability of pickling dead zones at the fixed location of the drive shaft assembly, improving the overall pickling coverage. Furthermore, when the first vertical rod 241 of the first hooking component 24 rotates, it drives the bent rod 242, the second vertical rod 243, and the drive shaft assembly to rotate, facilitating contact between complex parts of the drive shaft assembly and the pickling solution. The bent rod 242 can also pull the drive shaft assembly from one end, exposing the extension and retraction parts of the drive shaft assembly and allowing them to contact the pickling solution, further improving the overall pickling coverage.

[0035] By giving the second vertical rod 243 a certain length, the probability of the drive shaft assembly falling off is reduced after it is hung on the second vertical rod 243.

[0036] Please see Figure 4 and Figure 5 The top of each of the first vertical rods 241 is provided with a rotating assembly 28, and the top of the first plate 25 is provided with a transmission assembly 27. The transmission assembly 27 and the rotating assembly 28 work together to drive the first vertical rod 241 to rotate without affecting the vertical movement of the first vertical rod 241 with the second plate 29. The rotating assembly 28 includes: The rotating rod 281 is fixedly mounted on the top of the first vertical rod 241 and extends to the top of the first plate 25. The side wall of the rotating rod 281 is provided with a first sliding groove 282 arranged in a ring array. The first sliding groove 282 is filled with a first slider. The top of the first plate 25 and the second plate 29 are both provided with a first through hole for fitting the rotating rod 281.

[0037] Rotating assembly 28 also includes: Rotate the sleeve 283, which is rotatably located on the top of the first plate 25. The first slider is fixedly connected to the inner wall of the rotating sleeve 283 so that the rotating rod 281 can move along the inner wall of the rotating sleeve 283. The first gear 284 is fixedly sleeved on the outer wall of the rotating sleeve 283 to drive the rotating sleeve 283 and the rotating rod 281 to rotate.

[0038] In specific implementation, by rotating the sleeve 283 to the top of the first plate 25, and by using the first slide groove 282 and the first slider to make the rotating rod 281 move vertically along the inner wall of the rotating sleeve 283, the rotating rod 281 and the first vertical rod 241 can be driven to rotate when the transmission assembly 27 and the rotating assembly 28 cooperate, without affecting the first vertical rod 241 rising and falling with the second plate 29.

[0039] When the first vertical rod 241 rotates, it drives the bent rod 242 and the second vertical rod 243 to rotate, thereby driving the transmission shaft assembly to rotate from one end. This causes the other end of the transmission shaft assembly to drive the first vertical rod 241 of the second connecting assembly 22 to rotate, thus rotating the entire transmission shaft assembly. This ensures that the pickling solution fully contacts the transmission shaft assembly, improving the pickling effect. When the first vertical rod 241 moves vertically, the second plate 29 moves under the action of the connecting assembly 23, thereby driving the first vertical rod 241 to move. This extends the transmission shaft assembly from one end, exposing the extension and retraction parts of the transmission shaft assembly and allowing them to contact the pickling solution, further improving the comprehensiveness of the pickling. When the first vertical rod 241 moves, it drives the rotating rod 281 to move under the limitation of the first sliding groove 282 and the first slider, without affecting the subsequent rotation of the rotating rod 281.

[0040] The movement of the rotating rod 281 is limited by the first slide groove 282 and the first slider, and the rotating sleeve 283 can drive the rotating rod 281 and the first vertical rod 241 to rotate when it rotates with the first gear 284.

[0041] Please see Figure 6 and Figure 7 The transmission assembly 27 includes: A first gear ring 271 is rotatably mounted on the top of a first plate 25. A second plate 29 is rotatably mounted on the top of the first plate 25. The first plate 25 and the second plate 29 are coaxially designed. A first rotating rod and a second rotating rod are rotatably mounted on the top of the first plate 25. A second gear 276 and a third gear 273 are fixedly mounted on the side wall of the first rotating rod. A fourth gear 277 and a fifth gear 272 are fixedly mounted on the side wall of the second rotating rod. The second gear 276 meshes with the first gear ring 271. The fourth gear 277 meshes with the second gear ring 278. The third gear 273 and the fifth gear 272 are connected by a chain drive. The first servo motor 274 is fixedly mounted on the side wall of the first plate 25. The output shaft of the first servo motor 274 is fixedly mounted with a third rotating rod through a coupling. The third rotating rod is rotatably connected to the side wall of the first plate 25. A sixth gear 275 is fixedly mounted on the side wall of the third rotating rod. The sixth gear 275 meshes with the side of the second gear 276 away from the first gear ring 271.

[0042] Transmission assembly 27 also includes: The second slide groove 2791 is opened on the top of the first plate 25. The second slide groove 2791 contains a second slider, and the top of the second slider is fixedly connected to the bottom of the first toothed ring 271. The third slide groove 279 is located on the top of the first plate 25. The third slider is placed inside the third slide groove 279. The top of the third slider is fixedly connected to the bottom of the second gear ring 278. The second slide groove 279, the third slide groove 279, the second slider and the third slider are all designed in a ring shape so that the first gear ring 271 and the second gear ring 278 are rotatably connected to the first plate 25.

[0043] In specific implementation, the first servo motor 274 is started. The output shaft of the first servo motor 274 drives the third rotating rod to rotate. The third rotating rod drives the sixth gear 275 to rotate. The sixth gear 275 drives the second gear 276 to rotate. The second gear 276 drives the first gear ring 271, the first rotating rod, and the third gear 273 to rotate. The third gear 273 drives the fifth gear 272 to rotate via a chain. The fifth gear 272 drives the second rotating rod and the fourth gear 277 to rotate, thereby driving the second gear ring 278 to rotate. Thus, the second gear ring 278 and the first gear ring 271 rotate synchronously, thereby driving the first gear 284 to rotate. The first gear 284 drives the rotating sleeve 283, the rotating rod 281, and the first vertical rod 241 to rotate, thereby causing the transmission shaft assembly to rotate.

[0044] Through the cooperation of the second gear 276, the third gear 273 and the fourth gear 277, the first gear ring 271 and the second gear ring 278 can be driven by a single motor at the same time. This makes it easier for the same drive source to drive the rotation of multiple first vertical rods 241 arranged in a ring array, so as to synchronously drive the extension of multiple transmission shaft assemblies, which is convenient for operation and saves costs.

[0045] Example 2, please refer to Figures 8-10 The technical difference between this embodiment and Embodiment 1 is that the connecting component 23 includes: A connecting sleeve 231 is fixedly disposed at the bottom of the first plate 25. The outer wall of the connecting sleeve 231 penetrates the second plate 29. The bottom of the connecting sleeve 231 is fixedly connected to the top of the third plate 21. A second through hole for fitting the connecting sleeve 231 is provided at the top of the second plate 29. The movable through groove 236 is opened on the outer wall of the connecting sleeve 231 and arranged in a ring array. The inner wall of the movable through groove 236 is fitted with movable blocks 235. The side of the movable blocks 235 that is far apart from each other is fixedly connected to the inner wall of the second plate 29.

[0046] Connection component 23 also includes: The second servo motor 232 is fixedly mounted on the top of the first plate 25. The output shaft of the second servo motor 232 is fixedly provided with a threaded rod 233 extending into the connecting sleeve 231 via a coupling. The bottom of the threaded rod 233 is rotatably connected to the top of the third plate 21. The threaded tube 234 is threadedly connected to the side wall of the threaded rod 233, and the outer wall of the threaded tube 234 is fixedly connected to the side of the movable block 235 that is close to each other.

[0047] In specific implementation, the second servo motor 232 is started. The output shaft of the second servo motor 232 drives the threaded rod 233 to rotate. The threaded rod 233 drives the threaded tube 234 to move under the limit of the moving through groove 236 and the moving block 235, thereby driving the moving block 235 and the second plate 29 to move, so as to drive the first vertical rod 241 to move, thereby stretching it from one end of the transmission shaft assembly, so that the extension part of the transmission shaft assembly is exposed, which facilitates contact with the pickling solution and improves the comprehensiveness of pickling.

[0048] The third plate 21 and the first plate 25 are connected by the connecting sleeve 231 to ensure the stability of the third plate 21. The second plate 29 is sleeved on the outer wall of the connecting sleeve 231 to facilitate the vertical movement of the second plate 29 and facilitate the extension of the drive shaft assembly.

[0049] By placing electronic components such as the first servo motor 274 and the second servo motor 232 on the top of the first plate 25, contact with pickling solution is reduced, making it more suitable for pickling environments and reducing damage to electronic components, which is conducive to long-term use. In addition, it is convenient to pickle multiple drive shaft assemblies at the same time for batch pickling, thereby improving pickling efficiency.

[0050] This invention also provides a method for using an intelligent pickling device based on the processing of a drive shaft assembly. The method includes the following steps: S1: The first mounting component 24 and the second mounting component 22 limit the transmission shaft assembly from both ends, thereby allowing the transmission shaft assembly to be installed between the second plate 29 and the third plate 21. S2: After the drive shaft assembly is installed, the drive shaft assembly, the second plate 29 and the third plate 21 are transferred to the pickling tank 1 and immersed in the pickling solution in the pickling tank 1 to pickle the drive shaft assembly. S3: During the pickling process of the drive shaft assembly, the drive shaft assembly is stretched and rotated so that the pickling solution comes into contact with the entire surface of the drive shaft assembly.
