Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to an automatic polishing device for processing serpentine tubes. Background Technology

[0002] In industries such as air conditioning, heat exchangers, and new energy equipment, serpentine tubes are widely used due to their excellent heat exchange performance and compact structure. To ensure product quality and consistent appearance, serpentine tubes typically require surface polishing after forming or welding to remove oxide scale, weld slag, and fine burrs, thereby improving their corrosion resistance and subsequent assembly accuracy. Current serpentine tube polishing methods mostly employ manual positioning or simple fixtures with abrasive belt wheels. While these methods can meet basic processing requirements, they still have significant shortcomings in terms of efficiency, consistency, and safety. Furthermore, the high degree of manual intervention makes it difficult to meet the demands of mass automated production.

[0003] Especially during the polishing process, due to the complex shape and varying diameter of the serpentine tubes, existing devices often cannot quickly position and stably clamp tubes of different sizes. This leads to the tubes easily shifting and slipping during operation, affecting polishing accuracy and surface consistency, and even creating processing dead corners that require secondary adjustments. Furthermore, because loading, unloading, and movement rely on manual labor or fixed tracks, tube positioning is time-consuming, making it difficult to improve work efficiency and limiting the widespread application of such tube processing equipment. Therefore, an automatic polishing device for serpentine tube processing is proposed to solve the above problems. Utility Model Content

The moving carrier of the holding component moves with the electric slide rail 7 to realize the functions of workpiece feeding, alignment, or withdrawal; the upper surface of the sliding plate 8 is equipped with a clamping component for clamping and positioning the serpentine tube; the clamping component includes a hydraulic rod 9, which is a power input element, and its lower surface is fixedly connected to the upper surface of the sliding plate 8 to ensure that the clamping system maintains a stable structure in the moving state; a fixing ring 10 is fixedly connected to the output end of the hydraulic rod 9, which serves as the execution base for the clamping action, and its internal structure can achieve variable fit according to the diameter of the tube; multiple L-shaped connecting seats 11 are slidably connected inside the fixing ring 10, and the setting of the L-shaped connecting seats 11 enhances the flexibility of the internal structure of the fixing ring 10, making the clamping range more adaptive; L-shaped connecting... One side of the outer wall of the L-shaped connecting seat 11 is slidably connected to the inside of the fixing ring 10, allowing for fine-tuning of the position of the clamping block 13 through sliding. A fixing seat 12 is fixedly connected to one side of the outer wall of the L-shaped connecting seat 11. The fixing seat 12 serves as the mounting base for the clamping block 13, transmitting force and providing positioning. A clamping block 13 is provided on one side of the fixing seat 12, used to contact and clamp the outer wall of the serpentine pipe for stable fixation. A rotating plate 14 is rotatably connected to one side of the outer wall of the L-shaped connecting seat 11. Rotating the rotating plate 14 causes the fixing seat 12 to change position, enhancing the adaptability of the clamping block 13 to pipe fittings of different sizes. A hinge seat 15 is rotatably connected to one side of the outer wall of the rotating plate 14, further transmitting adjustment actions and providing auxiliary support. The hinge seat 15 has one side of its outer wall... A connecting ring 16 is fixedly connected, forming a closed loop structure to drive the coordinated movement of multiple clamping components. An adjusting screw 17 is threaded inside the connecting ring 16, used for fine adjustment of the clamping state. One end of the adjusting screw 17 is rotatably connected to one side of the outer wall of the fixed ring 10, enabling manual or servo fine-tuning. The polishing assembly includes a support frame 3, one side of which is fixedly connected to the inner wall of the protective cover 2, used to fix and install actuators such as the motor 5, maintaining stable operation during the polishing process. Symmetrical brackets 4 are fixedly connected to the upper surface of the support platform 1, serving as a guide and support structure for the polishing belt 6. A motor 5 is fixedly connected to the upper surface of the support frame 3, providing driving force to the polishing belt 6 and serving as the main actuator of the device.Polishing belts 6 are connected to both the output end of motor 5 and the two supports 4 via a transmission connection. Driven by motor 5, the polishing belts 6 move at high speed, efficiently polishing the serpentine tubes that pass beneath them.

[0032] Specifically, the clamping adjustment of the fixing ring 10 for different pipe diameters is achieved through the hydraulic rod 9. The adjusting screw 17, connecting ring 16, and multiple L-shaped connecting seats 11 are linked together, driving the clamping block 13 to stably clamp the pipe, ensuring that the serpentine pipe does not shift during processing. Subsequently, the entire structure is moved by the electric slide rail 7, allowing the serpentine pipe to accurately enter the working area of ​​the polishing component. The polishing belt 6 rotates at high speed to continuously polish the surface of the pipe, improving polishing efficiency and surface consistency, and adapting to the flexible processing needs of serpentine pipes of various specifications.

[0033] Reference Figures 1-4A rod 18 is fixedly connected to the lower surface of the clamping block 13. The rod 18 serves as a guide and support structure for the clamping block 13, ensuring stable axial positioning capability during vertical movement. The outer wall of the rod 18 is slidably connected to the inside of the fixed seat 12, achieving axial reciprocating motion of the rod 18 within the fixed seat 12 through sliding engagement, providing a stroke basis for clamping and releasing the clamping block 13. A telescopic rod 19 is fixedly connected to the top of the inner wall of the rod 18. The telescopic rod 19 is a driving element responsible for moving the sliding plate 20 vertically under control, completing clamping or releasing actions. A sliding plate 20 is fixedly connected to the lower surface of the telescopic rod 19. The sliding plate 20 is used to transmit the movement displacement of the telescopic rod 19 and to work in conjunction with the subsequent connecting structure to open or lock the locking block 23. The outer wall of the sliding plate 20 is slidably connected to the inner wall of the insertion rod 18, and relative motion control is achieved through sliding to ensure the stable and reliable operation of the locking block 23. A spring 21 is sleeved on the outer wall of the sliding plate 20. The spring 21 is used to provide a restoring force and automatically returns to the initial position after the sliding plate 20 is released from its driving action, forming a self-resetting mechanism for the locking structure of the locking block 23. The lower surface of the sliding plate 20 is rotatably connected to... A connecting plate 22 connects the sliding plate 20 and the locking block 23. The rotating connection structure causes the locking block 23 to rotate under the drive of the sliding plate 20, thus completing the locking or releasing action. The locking block 23 is rotatably connected to the outer wall of the connecting plate 22. The locking block 23 is the actual locking element; it automatically rotates and engages with the slot after the clamping block 13 is pressed down. One side of the outer wall of the locking block 23 is rotatably connected to the bottom of the inner wall of the insertion rod 18. The rotation point of the locking block 23 is set at the bottom of the insertion rod 18 to ensure precise movement. The outer wall of the locking block 23 engages with the inner wall of the fixing seat 12, thereby locking... The outward flip of block 23 and its engagement with the slot effectively prevent the clamping block 13 from accidentally loosening during operation, thus improving clamping stability. The fixed base 12 has a slot inside for the clamping block 23 to engage. This slot structure provides the clamping block 23 with an accurate limiting position, ensuring positioning accuracy and operational reliability. The upper end of spring 21 is fixedly connected to the upper side of the inner wall of the insert rod 18. The fixed upper end of spring 21 ensures that the deformation direction of spring 21 is controlled when compressed. The lower end of spring 21 is fixedly connected to the upper surface of sliding plate 20, providing elastic force to push sliding plate 20 to reset, thereby achieving continuous locking of the clamping block 23.

[0034] Specifically, the sliding connection between the insertion rod 18 and the fixed base 12 enables the clamping block 13 to have an elastic telescopic function. Combined with the up-and-down movement of the telescopic rod 19 and the sliding plate 20, the connecting plate 22 is rotated, which in turn drives the locking block 23 to achieve precise opening and closing operation within the insertion rod 18. After the locking block 23 enters the slot set in the inner wall of the fixed base 12, the clamping block 13 can be automatically locked, ensuring the position fixation and stability of the pipe fitting during the clamping process, and effectively improving the working reliability and safety performance of the entire clamping assembly.

[0035] Working principle: When the polishing device is needed, the matching clamp 13 is first inserted into the fixed base 12 through the insertion rod 18. At this time, the reaction force of the spring 21 facilitates the movement of the sliding plate 20. Then, the movement of the sliding plate 20 causes the locking block 23 on one side of the connecting plate 22 to engage inside the fixed base 12 for fixation. Then, by placing the tube inside the fixed ring 10, the adjusting screw 17 is rotated to bring the connecting ring 16 closer to the fixed ring 10. The movement of the connecting ring 16 facilitates the rotation of one side of the hinge base 15. The rotating plate 14 drives the L-shaped connecting seat 11 to slide inside the fixing ring 10. The movement of the L-shaped connecting seat 11 achieves the effect of clamping the pipe fitting with the clamping block 13. Then, the hydraulic rod 9 is activated to adjust the height of the pipe fitting inside the fixing ring 10. At this time, the electric slide rail 7 is activated, which drives the sliding plate 8 to move closer to the lower side of the polishing belt 6. Then, the motor 5 is activated to drive the two intersecting polishing belts 6 to rotate. The polishing belts 6, which are flexible, are in close contact with the outside of the pipe fitting, thus achieving the effect of efficient polishing of the pipe fitting.
