Description

Technical Field

[0001] This invention belongs to the field of laser cladding technology, and specifically relates to a laser cladding sealing device. Background Technology

[0002] Laser cladding sealing devices are specialized equipment based on laser cladding technology, specifically designed for processing the inner walls of truncated conical cylinders. Their core function is to melt a pre-set cladding material using a laser beam, forming a metallurgical bond with the base material of the truncated conical cylinder's inner wall. This creates a dense, wear-resistant, and corrosion-resistant cladding layer on the inner wall, thereby improving the sealing performance of the truncated conical cylinder's inner wall, enhancing its resistance to wear and corrosion, and extending its service life. They are widely used in the processing and repair of truncated conical cylinder components with high sealing performance requirements in fields such as machinery manufacturing, petrochemicals, and aerospace.

[0003] However, existing laser cladding sealing devices still have many shortcomings in practical applications, making it difficult to meet the high-efficiency and precise cladding requirements of irregularly shaped workpieces such as truncated conical cylinders. Specifically, this is reflected in the following two aspects: First, existing devices mostly rely on large and expensive automated components such as robotic arms to adjust and move the cladding nozzle, which not only results in high equipment purchase costs but also high difficulty and cost of subsequent maintenance. At the same time, these devices usually require operators to have a high level of proficiency in software programming and debugging, and require precise setting of robotic arm movement trajectories, laser parameters, etc., which places stringent demands on personnel skills, increases the company's personnel training costs, and is prone to affecting the cladding quality due to operational errors. Secondly, the clamping mechanisms of existing devices are mostly rigid designs with poor adaptability, making it difficult to achieve stable and precise clamping of irregularly shaped workpieces with curved contours, such as truncated conical cylinders. In particular, for the cladding process of the inner wall of truncated conical cylinders, the uneven thickness of the cladding layer is often caused by insufficient clamping coaxiality and difficulty in adjusting the nozzle posture. In addition, the transmission system of some devices has poor synchronization, and the rotation of the workpiece and the movement of the nozzle are not synchronized, which further aggravates the problems of poor uniformity of the cladding layer and unstable sealing performance, making it impossible to guarantee the cladding sealing quality of the inner wall of the truncated conical cylinder.

[0016] The beneficial effects of this invention compared to the prior art are as follows:

[0017] I. Reduce equipment costs and operational complexity to meet the actual needs of small and medium-sized enterprises.

[0018] Addressing the issues of high equipment purchase costs, difficult maintenance, and stringent software programming and debugging skills required by existing technologies that rely on large and expensive automated components such as robotic arms, this invention achieves a dual reduction in cost and operational barriers through optimized mechanical structure design. Utilizing a collaborative transmission structure of the base, lifting column, first threaded rod, slide rail, and slider, coupled with conventional power components such as the first electric push rod and drive motor, the invention eliminates the need for a robotic arm to adjust and move the cladding nozzle's posture, significantly reducing equipment purchase costs. Simultaneously, processes such as workpiece clamping (clamping motor-driven clamping mechanism, knob-operated locking mechanism), height adjustment (second electric push rod), and posture calibration (adjustment mechanism) are all achieved through simple mechanical transmission or button control, requiring no complex software programming. Operators can be trained quickly, significantly reducing enterprise personnel training costs and perfectly meeting the core needs of SMEs for low-cost, easy-to-operate equipment. Furthermore, the overall structure of the equipment is primarily mechanically connected, without complex electronic control modules. Maintenance only requires servicing conventional components such as slide rails, gears, and conical wheels, making maintenance significantly less difficult and costly than existing equipment relying on robotic arms.

[0019] II. Improve clamping adaptability and stability, and ensure workpiece clamping coaxiality.

[0020] To address the problems of existing clamping mechanisms, such as rigid design, poor adaptability, difficulty in stably clamping irregularly shaped workpieces like truncated conical cylinders, and susceptibility to insufficient coaxiality affecting cladding quality, this invention achieves a comprehensive upgrade in clamping performance through the collaborative design of a dedicated clamping mechanism and a snap-fit ​​mechanism. Regarding clamping adaptability, the clamping mechanism employs a transmission structure of "first gear + multiple sets of racks + clamping rods," coupled with an adaptive clamping unit composed of an arc-shaped slider and a spring. The elastic force of the spring drives the arc-shaped clamping block to tightly conform to the arc-shaped surface of the large end of the truncated conical cylinder, effectively compensating for minor deviations in workpiece dimensions and adapting to the clamping requirements of truncated conical cylinders of different specifications. The snap-fit ​​mechanism, controlled by a knob, allows for quick replacement of friction grippers that match the size of the small end of the truncated conical cylinder, further expanding the device's adaptability range. In terms of clamping stability and coaxiality, multiple sets of clamping rods are circumferentially staggered. Combined with the design of the rotating rollers at the corners of the clamping rods and on the arc-shaped clamping blocks, this reduces the frictional resistance and surface wear during workpiece rotation. It also ensures the coaxiality of the clamping by uniformly clamping the workpiece at multiple points. At the same time, the rotating column and the friction gripper are connected by the mutual cooperation of the limiting groove and the limiting block, combined with the circumferential limiting of the snap-fit ​​mechanism, to ensure stable transmission of rotational power and avoid slippage or displacement of the workpiece during rotation, laying the foundation for subsequent precise cladding.

[0021] III. Optimize transmission synchronization to achieve uniform and precise cladding and sealing.

[0022] Addressing the core issues of poor synchronization in existing device transmission systems, leading to asynchronous workpiece rotation and nozzle movement, uneven cladding layer thickness, and unstable sealing performance, this invention's synchronization mechanism constructs a highly efficient and precise transmission link. The synchronization mechanism utilizes a multi-stage meshing transmission of "driving gear-driven gear" and "driving conical wheel-transmission conical wheel-driven conical wheel," enabling the drive shaft to simultaneously drive the truncated conical cylinder and the second threaded rod to rotate at the same angular velocity. Combined with the design where "the pitch of the second threaded rod is the same as the lead of the cladding nozzle," for every revolution of the truncated conical cylinder, the second threaded rod rotates synchronously by one revolution, driving the cladding nozzle to move precisely one lead distance along the horizontally set second slide rail, forming a uniform spiral cladding trajectory. This synchronous transmission design fundamentally solves the problem of asynchronous movement between the cladding nozzle and workpiece rotation in existing technologies, ensuring a uniform cladding layer thickness, effectively improving the sealing performance of the inner wall of the truncated conical cylinder, avoiding the risk of seal failure due to uneven cladding layer thickness, and meeting the processing requirements of high-sealing-performance workpieces in fields such as machinery manufacturing and petrochemicals.

[0023] IV. Reduce cladding material waste and improve the forming quality of the cladding layer.

[0024] To address the problems in existing technologies where metal powder is affected by gravity, resulting in deviations in the landing point and interference with the formation of the cladding layer after rebound, leading to material waste and poor forming quality, this invention achieves a dual improvement in cladding material utilization and forming quality through structural optimization. On one hand, the adjustment mechanism, through a structure of "sliding sleeve + threaded sleeve + second connecting rod," can precisely adjust the second slide rail to a horizontal state (parallel to the inner wall of the bottom of the truncated conical cylinder), ensuring that the metal powder sprayed by the cladding nozzle can deposit perpendicularly to the inner wall of the workpiece, avoiding deviations in the metal powder landing point caused by nozzle posture deviations, and ensuring that the metal powder accurately enters the molten pool. On the other hand, the precise spiral cladding trajectory ensured by the synchronization mechanism allows the metal powder to evenly cover the preset processing area, reducing ineffective deposition in non-processing areas. Meanwhile, the incident angle of the vertically deposited metal powder is 0° when it comes into contact with the inner wall of the workpiece. Even if it bounces back, it will be pushed back by the subsequent metal powder. In addition, the molten pool has a certain degree of adhesion, which can effectively reduce the probability of metal powder rebound and prevent it from jumping to non-processing areas. This reduces the waste rate of cladding material and avoids the interference of rebounding metal powder on the preset cladding layer, making the cladding layer more compact and the forming quality more stable, further enhancing the wear resistance, corrosion resistance and service life of the workpiece.

The clamping mechanism includes a ring of clamping rods 18 slidably provided on the driving column 7, which limits the large end of the truncated conical cylinder. A driving shaft 15 is rotatably provided inside the first threaded rod 3, and a rotating column 8 is rotatably provided at the end of the fixed column 10. The driving shaft 15 is fixedly connected to the rotating column 8. A detachable friction gripper 9 is provided on the side via a snap-fit ​​mechanism to limit the small end of the truncated cone. A second slide rail 11 is provided at the lower end of the first threaded rod 3. The second slide rail 11 is used to extend into the interior of the truncated cone. A second threaded rod 12 is rotatably provided inside the second slide rail 11. A second slider 13 is slidably provided on the second slide rail 11 and is screwed to the second threaded rod 12. A cladding nozzle 14 is fixedly provided on the second slider 13 to spray the inner wall of the truncated cone. The left end of the second slide rail 11 is hinged to the fixed column 10. The second threaded rod 12 is connected to the drive shaft 15 via a synchronization mechanism to drive the second threaded rod 12 and the drive shaft 15 to rotate synchronously at the same angular velocity. The right end of the second slide rail 11 is connected to the first threaded rod 3 via an adjustment mechanism to adjust the angle of the second slide rail 11.

[0043] The base 1 is a cuboid structure, with its upper surface remaining horizontal. The hinge axis between the right end of the first threaded rod 3 and the lifting column 2 is horizontally positioned along the front-to-back direction. A lifting groove with an open top is provided on the right side of the upper surface of the base 1, and the lower end of the lifting column 2 is slidably inserted into the lifting groove. A first mounting groove is provided on the bottom surface inside the lifting groove, and a second electric push rod 49 is fixedly installed inside the first mounting groove. The telescopic end of the second electric push rod 49 is vertically upward and fixedly connected to the lower end of the lifting column 2.

[0044] The first slide rail 4 is fixedly installed on the upper left side of the lifting column 2, and extends horizontally in the left-right direction. A first sliding groove extending horizontally in the left-right direction is provided on the lower end face of the first slide rail 4. The first sliding groove is a T-shaped groove. The first slider 5, a T-shaped block, is slidably installed inside the first sliding groove in the left-right direction, with its lower end extending to the outer side of the lower end of the first sliding groove. A first electric push rod 48 is fixedly installed inside the inner right wall of the first sliding groove. The telescopic end of the first electric push rod 48 faces left and is fixedly connected to the first slider 5. The upper end of the first connecting rod 6 is hinged to the lower end of the first slider 5, and the lower end of the first connecting rod 6 is hinged to the outer surface of the first threaded rod 3. The hinge axes of the upper and lower ends of the first connecting rod 6 are horizontally arranged in the front-back direction. The extension and retraction of the first electric push rod 48 drives the first slider 5 to slide left and right inside the first slide groove. The sliding of the first slider 5 drives the upper end of the first connecting rod 6 to slide left and right. The first connecting rod 6 drives the first threaded rod 3 to rotate around the hinge axis at its right end, thereby adjusting the angle of the first threaded rod 3.

[0045] A drive motor 47 is fixedly installed inside the end of the first threaded rod 3 near the lifting column 2. The output shaft of the drive motor 47 faces away from the lifting column 2 and coincides with the axis of the first threaded rod 3. The end of the drive shaft 15 near the lifting column 2 is fixedly connected to the output shaft of the drive motor 47. The end of the drive shaft 15 away from the lifting column 2 passes through the drive column 7 and the fixed column 10 in sequence and is fixedly connected to the rotating column 8. The drive motor 47 drives the drive shaft 15 to rotate, the drive shaft 15 drives the rotating column 8 to rotate, and the rotating column 8 drives the friction gripper 9 to rotate through the snap-fit ​​mechanism. The friction gripper 9 drives the truncated conical cylinder to rotate.

[0046] The clamping mechanism also includes a first gear 16, a rack 17, a rotating roller 19, an arc-shaped slider 21, an arc-shaped clamping block 22, a spring 23, a worm gear 24, a connecting sleeve 25, a worm 26, and a clamping motor 27.

[0047] A connecting sleeve 25 is rotatably mounted inside the drive column 7, and the connecting sleeve 25 is rotatably sleeved on the outside of the drive shaft 15. A first gear 16 and a worm gear 24 are respectively fixedly mounted at both ends of the connecting sleeve 25, and both the first gear 16 and the worm gear 24 are rotatably sleeved on the outside of the drive shaft 15. A ring of racks 17 is slidably inserted inside the drive column 7. The ring of racks is arranged in a circular array around the axis of the drive column 7, and all racks 17 mesh with the first gear 16. A clamping rod 18 is fixedly mounted on one end of the outer side of each rack 17. The clamping rod 18 is an L-shaped rod structure, including a transverse rod and a longitudinal rod. The transverse rod is perpendicular to the axis of the drive column 7, and the longitudinal rod is parallel to the axis of the drive column 7. One end of the transverse rod is fixedly connected to the rack 17, and the other end of the transverse rod is fixedly connected to the end of the longitudinal rod near the lifting column 2. A rotating roller 19 is rotatably mounted on the end of the transverse rod away from the rack 17, and the rotating roller 19 is located on the side of the transverse rod away from the lifting column 2. A first arc-shaped groove 20 is provided on the end face of the longitudinal rod near the drive column 7. An arc-shaped slider 21 is slidably disposed inside the first arc-shaped groove 20. Multiple sets of springs 23 are fixedly disposed between the arc-shaped slider 21 and the inner wall of the first arc-shaped groove 20. An arc-shaped clamping block 22 is fixedly disposed on one end of the outer side of the arc-shaped slider 21. A rotating roller 19 is rotatably disposed on the end face of the arc-shaped clamping block 22 near the drive column 7. A clamping motor 27 is fixedly disposed on the drive column 7. The output shaft of the clamping motor 27 extends into the drive column 7. A worm gear 26 is fixedly disposed on the output shaft of the clamping motor 27. The worm gear 26 meshes with a worm wheel 24.

[0048] The clamping motor 27 drives the connecting sleeve 25 to rotate through the meshing worm gear 24 and worm 26. The connecting sleeve 25 drives the first gear 16 to rotate. The first gear 16 drives all the racks 17 to slide outward. The racks 17 drive all the clamping rods 18 to slide outward. Then the large end of the truncated conical cylinder is placed between a ring of outwardly expanding clamping rods 18. Then, the clamping motor 27 is controlled to rotate in the reverse direction, thereby driving the first gear 16 to rotate in the reverse direction. The first gear 16 drives all the racks 17 to slide inward, and the racks 17 drive all the clamping rods 18 to slide inward, so that the longitudinal sections of all the clamping rods 18 gradually approach the large end of the truncated cone cylinder, until the arc-shaped clamping block 22 on the longitudinal section of the clamping rod 18 contacts the outer conical surface at the large end of the truncated cone cylinder. Then, under the pulling force of the racks 17, the arc-shaped slider 21 slides inside the first arc-shaped groove 20, and the spring 23 undergoes elastic deformation, thereby adjusting the angle of the arc-shaped clamping block 22, thus ensuring that the rotating roller 19 on the arc-shaped clamping block 22 is in contact with the outer conical surface at the large end of the truncated cone cylinder. At this time, the large end of the truncated cone cylinder contacts the rotating roller 19 on the transverse section of all the clamping rods 18, thereby clamping and limiting the large end of the truncated cone cylinder through the clamping mechanism. When it is necessary to loosen the large end of the truncated cone, the clamping motor 27 is controlled to rotate forward again, so that all the racks 17 drive the clamping rods 18 to slide outward, thereby loosening the large end of the truncated cone. The arc-shaped slider 21 returns to its initial angle under the action of the spring 23.

[0049] The locking mechanism also includes a locking block 28, a turntable 29, a toggle pin 31, a rotating shaft 32, a knob 33, and a torsion spring 34.

[0050] The friction gripper 9 includes a mounting ring, radial rods, and parallel rods. A ring of circularly arranged limiting grooves is provided on the outer cylindrical surface of the rotating column 8, extending along the axis of the rotating column 8. The mounting ring is detachably fitted onto the outside of the rotating column 8. A ring of circularly arranged limiting blocks is provided on the inner cylindrical surface of the mounting ring, each limiting block slidingly engaging with its corresponding limiting groove. Through the interaction of the limiting blocks and the limiting grooves, the friction gripper 9 can be detached from the rotating column 8 while simultaneously rotating synchronously with it. A ring of circularly arranged radial rods is fixedly provided on the outer cylindrical surface of the mounting ring, extending radially along the mounting ring. A parallel rod is fixedly provided at one end of each radial rod, located on the side of the radial rod closer to the lifting column 2, with its extension direction parallel to the axis of the mounting ring. A locking groove is provided at the end of the parallel rod away from the radial rod, engaging with the small end of the truncated conical cylinder.

[0051] A rotating cavity is provided inside the rotating column 8. A circular turntable 29 is rotatably mounted inside the rotating cavity, with its axis coinciding with the axis of the rotating column 8. A second arc-shaped groove 30 is arranged in a circular array on the turntable 29. The distance between one end of the second arc-shaped groove 30 and the axis of the rotating column 8 is less than the distance between the other end of the second arc-shaped groove 30 and the axis of the rotating column 8. A rotating shaft 32 is rotatably inserted into the side wall of the rotating cavity away from the fixed column 10. One end of the rotating shaft 32 is fixedly connected to the turntable 29, and a knob 33 is fixedly mounted on the outer end of the rotating shaft 32. A torsion spring 34 is sleeved on the outer side of the rotating shaft 32, with one end of the torsion spring 34 fixedly connected to the rotating shaft 32 and the other end fixedly connected to the rotating column 8.

[0052] A sliding groove is provided on the inner wall of each limiting groove near the axis of the rotating column 8. The sliding grooves are arranged radially along the rotating column 8, and the inner end of each sliding groove is connected to the inside of the rotating cavity through a connecting groove. A locking block 28 is slidably disposed inside each sliding groove. A contact slope is provided on the outer end of each locking block 28, and the contact slope is located on the side away from the fixed column 10. A deflector 31 is fixedly disposed on the inner end of each locking block 28. The deflector 31 is slidably disposed inside the connecting groove. The deflector 31 corresponds one-to-one with the second arc-shaped sliding groove 30 on the turntable 29. The end of each deflector 31 away from the locking block 28 is slidably inserted into the corresponding second arc-shaped sliding groove 30.

[0053] When no external force is applied to the knob 33, the turntable 29 is at its initial angle under the action of the torsion spring 34. At this time, all the pins 31 are located at the end of the corresponding second arc-shaped slide groove 30 away from the axis of the rotating column 8. Driven by the pins 31, the outer end of all the locking blocks 28 extends to the outside of the slide groove and into the limiting groove. When it is necessary to install the friction claw 9, the knob 33 is rotated. The knob 33 drives the turntable 29 to rotate through the rotating shaft 32. At this time, the torsion spring 34 undergoes elastic deformation. The turntable 29 drives all the pins 31 to slide synchronously. The pins 31 slide towards the end of the second arc-shaped slide groove 30 closer to the axis of the rotating column 8. The pins 31 drive all the locking blocks 28 to slide into the slide groove, so that the outer end of the locking block 28 also slides into the slide groove. At this time, the friction claw 9 is sleeved on the outside of the rotating column 8, and the limiting block on the inner side of the mounting ring of the friction claw 9 is locked into the corresponding limiting groove. Then, release the knob 33. Under the rebound force of the torsion spring 34, the turntable 29 rotates in the opposite direction. The turntable 29 drives all the shift pins 31 to slide in the opposite direction. The shift pins 31 slide towards the end of the second arc-shaped slide groove 30 away from the axis of the rotating column 8. The shift pins 31 drive all the locking blocks 28 to slide out of the slide groove until the outer end of the locking block 28 slides back to the outside of the slide groove and extends into the limiting groove. At this time, the outer end of the locking block 28 contacts the limiting block on the inner side of the mounting ring of the friction claw 9. The locking block 28 limits the friction claw 9 to ensure that the friction claw 9 will not disengage from the rotating column 8. At the same time, the friction claw 9 can also rotate synchronously with the rotating column 8.

[0054] The synchronization mechanism includes a driving gear 38, a first mounting base 39, a driven gear 40, a second mounting base 41, a mounting rod 42, a transmission cone wheel 43, a rotating sleeve 44, a driven cone wheel 45, and a driving cone wheel 46.

[0055] A clearance groove is provided on the side wall of the left end of the fixed column 10, and a drive gear 38 is provided in the clearance groove. The drive gear 38 is fixedly sleeved on the outside of the drive shaft 15. A first mounting seat 39 is fixedly provided at the lower end of the outer side of the fixed column 10. A driven gear 40 is rotatably provided inside the first mounting seat 39. The drive gear 38 meshes with the driven gear 40. A drive cone wheel 46 is fixedly provided at the right end of the driven gear 40. A second mounting seat 41 is also fixedly provided on the outer side of the lower end of the fixed column 10. A horizontal mounting rod 42 is fixedly provided on the second mounting seat 41. A transmission cone wheel 43 is rotatably provided at the end of the mounting rod 42. A rotating sleeve 44 is rotatably sleeved on the outer side of the mounting rod 42. The rotating sleeve 44 is rotatably connected to the second mounting seat 41 and fixedly connected to the left end of the second slide rail 11. The left end of the second threaded rod 12 extends to the outer side of the left end of the second slide rail 11. A driven cone wheel 45 is fixedly provided at the left end of the second threaded rod 12. The driving cone wheel 46 and the driven cone wheel 45 are located on both sides of the transmission cone wheel 43 and are both engaged with the transmission cone wheel 43.

[0056] The driving gear 38 and the driven gear 40 have the same specifications, and the driving bevel gear 46, the driven bevel gear 45, and the transmission bevel gear 43 have the same specifications.

[0057] When the drive shaft 15 rotates, it drives the drive cone wheel 46 to rotate via the meshing drive gear 38 and driven gear 40. The drive cone wheel 46 drives the transmission cone wheel 43 to rotate, which in turn drives the driven cone wheel 45 to rotate. The driven cone wheel 45 then drives the second threaded rod 12 to rotate. Since the drive gear 38 and driven gear 40 are of the same specifications, and the drive cone wheel 46, driven cone wheel 45, and transmission cone wheel 43 are also of the same specifications, the rotational angular velocity of the second threaded rod 12 is consistent with the rotational angular velocity of the drive shaft 15.

[0058] The adjustment mechanism includes a sliding sleeve 35, a threaded sleeve 37, and a second connecting rod 36.

[0059] A threaded section is provided on the right side of the outer surface of the first threaded rod 3. A sliding sleeve 35 is slidably sleeved on the outer side of the threaded section. A threaded sleeve 37 is rotatably provided on the right end of the sliding sleeve 35 and screwed onto the outer side of the threaded section. A second connecting rod 36 is provided between the sliding sleeve 35 and the right end of the second slide rail 11. The upper end of the second connecting rod 36 is hinged to the sliding sleeve 35, and the lower end of the second connecting rod 36 is hinged to the outer side of the right end of the second slide rail 11. The hinge axes of the upper and lower ends of the second connecting rod 36 are horizontally arranged along the front-back direction.

[0060] When the threaded sleeve 37 is rotated, it slides axially on the outside of the first threaded rod 3, causing the sliding sleeve 35 to slide synchronously. The sliding sleeve 35 causes the upper end of the second connecting rod 36 to slide synchronously, and through the second connecting rod 36, the right end of the second slide rail 11 rotates around the rotating sleeve 44 at the left end, thereby adjusting the angle of the second slide rail 11.

[0061] The working principle of this invention is as follows:

[0062] The first stage is the clamping preparation stage: Base 1 provides stable support for the entire device. First, by controlling the extension and retraction of the second electric push rod 49, the lifting column 2 slides vertically on the base 1, thereby adjusting the overall height of the rotating column 8, the fixed column 10, and the first threaded rod 3 to provide a suitable height for placing the truncated cone. Then, the large end of the truncated cone is placed on the base 1 through the rotating column 8, so that the outer wall of the truncated cone contacts the upper surface of the base 1. The horizontal plane at the upper end of the base 1 is used to achieve the initial positioning of the truncated cone, and the inner wall of the bottom of the truncated cone remains horizontal. At the same time, the extension and retraction of the first electric push rod 48 fixed inside the first slide rail 4 is controlled, which drives the first slider 5 to slide within the first slide rail 4. Through the first connecting rod 6 rotatably connected between the first slider 5 and the first threaded rod 3, the first threaded rod 3 is pulled or pushed to finely adjust its posture around its rotational connection point with the lifting column 2, thereby adjusting the spatial position of the clamping mechanism to ensure that the clamping mechanism can accurately align with the large end of the truncated cone, preparing for subsequent workpiece fixing.

[0063] The second stage is the workpiece fixing stage: In this stage, the large end and small end of the truncated cone are fixed through the clamping mechanism and the snap-fit ​​mechanism, respectively. When the clamping mechanism is working, the clamping motor 27 is energized and runs. The clamping motor 27 drives the connecting sleeve 25 to rotate through the meshing worm gear 24 and worm 26. The connecting sleeve 25 drives the first gear 16 to rotate. The first gear 16 drives all the racks 17 to slide inward. The racks 17 drive all the clamping rods 18 to gradually move towards the center. During the approach process, the rotating roller 19 connected at the corner of the clamping rod 18 first contacts the outer wall of the large end of the truncated cone. The rotating roller 19 can reduce the wear during the subsequent rotation of the truncated cone. The clamping mechanism reduces wear and tear and provides resistance, while also assisting in calibrating the workpiece position. As the clamping rod 18 continues to move closer, the arc-shaped clamping block 22 at the end of the clamping rod 18 fits against the outer wall of the large end of the truncated conical cylinder. At this time, the arc-shaped slider 21 fixed at the top of the arc-shaped clamping block 22 slides adaptively within the first arc-shaped slide groove 20, compressing the multiple sets of springs 23 set within the first arc-shaped slide groove 20. The reverse elastic force generated by the springs 23 causes the arc-shaped clamping block 22 to fit tightly against the arc-shaped surface of the large end of the truncated conical cylinder, achieving adaptive clamping and compensating for minor deviations in workpiece dimensions. In addition, the first gear 16, worm gear 24, and connecting sleeve 25 are all hollow to ensure that the drive shaft 15 can pass through smoothly without interfering with power transmission. After the large end is fixed, the small end is fixed by a snap-fit ​​mechanism: the operator rotates the knob 33 on the outside of the rotating column 8, which drives the rotating shaft 32 and the turntable 29 to rotate, and the torsion spring 34 is twisted to store elastic potential energy; the second arc-shaped slide groove 30 on the surface of the turntable 29 drives multiple sets of snap-fit ​​blocks 28 to retract radially inward into the interior of the rotating column 8 through the push pin 31, releasing the obstruction to the installation of the friction gripper 9; the friction gripper 9, which matches the size of the small end of the truncated cone, is fitted onto the outer wall of the rotating column 8, and the knob is released. After button 33, torsion spring 34 resets and drives turntable 29 to rotate in the opposite direction. Pulley 31 drives block 28 to slide outward until one end of block 28 slides back to the outside of sliding groove and extends into the limiting groove. At this time, one end of block 28 contacts the limiting block on the inner side of the mounting ring of friction gripper 9, realizing the circumferential limiting and fixing of friction gripper 9 and rotating column 8, so that friction gripper 9 and the outer wall of the small end of truncated cone are in close frictional contact, completing the complete fixing of both ends of the workpiece.

[0064] The third stage is the attitude calibration stage: the core is to adjust the second slide rail 11 to a horizontal state through the adjustment mechanism, laying the foundation for the smooth movement of the cladding nozzle 14. Since the end of the second slide rail 11 away from the adjustment mechanism is rotatably connected to the second mounting base 41, this connection provides a stable fulcrum for adjustment. The operator rotates the threaded sleeve 37 on the side of the sliding sleeve 35 closest to the lifting column 2. Because the threaded sleeve 37 is threadedly engaged with the first threaded rod 3 and can rotate relative to the sliding sleeve 35, the rotational motion of the threaded sleeve 37 is converted into the linear sliding of the sliding sleeve 35 along the axial direction of the first threaded rod 3. The sliding sleeve 35 is rotatably connected to the second slide rail 11 through the second connecting rod 36 at the bottom. When sliding, the second connecting rod 36 generates a pushing or pulling force on the second slide rail 11, causing the second slide rail 11 to make a fine angle adjustment with the rotational connection point with the second mounting base 41 as the fulcrum. At the same time, it causes the second slide rail 11 to translate along the axial direction of the first threaded rod 3. Through the synergistic effect of the angle fine adjustment and the translation adjustment, the second slide rail 11 is accurately adjusted to a horizontal state.

[0065] The fourth stage is the cladding motion stage: First, the second electric push rod 49 is extended again, driving the lifting column 2 and the entire upper structure to rise, causing the truncated cone cylinder to disengage from the base 1, preventing damage to the workpiece during rotation. Then, the drive motor 47 fixed inside the first threaded rod 3 is activated. The output of the drive motor 47 drives the drive shaft 15 to rotate. The drive shaft 15, through a snap-fit ​​mechanism and transmission relationship with the rotating column 8, drives the friction gripper 9 to rotate synchronously, thereby driving the truncated cone cylinder to rotate. When the drive shaft 15 rotates, it drives the drive cone wheel 46 to rotate through the meshing drive gear 38 and driven gear 40. The drive cone wheel 46 drives the transmission cone wheel 43 to rotate, the transmission cone wheel 43 drives the driven cone wheel 45 to rotate, and the driven cone wheel 45 drives the second threaded rod 12 to rotate. Since the driving gear 38 and driven gear 40 have the same specifications, and the driving cone wheel 46, driven cone wheel 45, and transmission cone wheel 43 also have the same specifications, the rotational angular velocity of the second threaded rod 12 is consistent with the rotational angular velocity of the drive shaft 15, achieving precise coordination between the movement of the cladding nozzle 14 and the rotation of the workpiece. Because the second threaded rod 12 is threadedly connected to the second slider 13, the rotational motion of the second threaded rod 12 is converted into the linear sliding motion of the second slider 13 along the horizontal second slide rail 11. Since the second threaded rod 12 rotates at the same angular velocity as the truncated cone, for every revolution of the truncated cone, the second threaded rod 12 also rotates once. The second slider 13 drives the cladding nozzle 14 to move exactly one pitch (lead) distance, ultimately forming a uniform and continuous spiral cladding sealing layer on the inner wall of the truncated cone.
