[0009] The tensioning roller is positioned on the running path of the polishing belt;

[0010] An elastic component is used to make the outer surface of the tensioning roller fit tightly against the outer surface of the polishing belt;

[0014] The support frame has two guide rods arranged in parallel with the mounting plate, and the two guide rods are used to install multiple nozzles respectively.

[0015] In some embodiments, a workpiece loading shaft for placing workpieces is also included, the workpiece loading shaft being disposed below the polishing belt, and the two guide rods being disposed parallel to each other on both sides of the workpiece loading shaft.

[0016] In some embodiments, the system further includes a loading and unloading mechanism, which includes a turntable platform and a second drive motor for driving the turntable platform to rotate.

[0017] There are two workpiece loading shafts, symmetrically arranged on both sides of the turntable platform; the turntable platform is used to drive the two workpiece loading shafts to rotate and exchange positions with each other.

[0018] In some embodiments, the turntable platform is provided with shaft seats that correspond one-to-one with the workpiece loading shaft;

[0041] Reference Figures 1 to 4 This embodiment proposes a polishing device 100, including a polishing mechanism 1 and a water jet mechanism 2. The polishing mechanism 1 includes:

[0042] Active roller 11;

[0043] Two driven rollers 12 are arranged opposite each other on both sides of the driving roller 11;

[0044] Polishing belt 13 is fitted onto two driven rollers 12 and a driving roller 11;

[0045] The first drive motor 14 is connected to the drive roller 11 and is used to drive the drive roller 11 to drive the two driven rollers 12 and the polishing belt 13 to rotate together.

[0046] The tensioning roller 15 is positioned on the running path of the polishing belt 13;

[0047] The elastic component 16 is used to make the outer surface of the tension roller 15 fit tightly against the outer surface of the polishing belt 13;

[0048] The water jet mechanism 2 includes multiple nozzles 21, which are symmetrically arranged on both sides of the polishing belt 13.

[0049] In this embodiment, the active roller 11 and the two driven rollers 12 form a triangular arrangement, and the polishing belt 13 is fitted between the three to form a closed loop running path. The first drive motor 14 drives the active roller 11, thereby driving the driven rollers 12 on both sides to rotate synchronously with the polishing belt 13, forming a continuous and stable motion path. This triangular arrangement not only facilitates the formation of a stable drive system, but also provides the polishing belt 13 with a sufficient envelope angle and good fit, making it convenient for the polishing belt 13 to polish the surface of the workpiece to be polished.

[0050] To ensure that the polishing belt 13 remains under proper tension during operation and to guarantee the continuity and uniformity of the polishing process, this embodiment includes a tensioning roller 15. The outer surface of the tensioning roller 15 is attached to the outer surface of the polishing belt 13 and positioned along the movement path of the polishing belt 13. A continuous thrust is provided by the elastic component 16, ensuring that the tensioning roller 15 always moves towards the polishing belt 13, thereby dynamically adjusting the tension of the polishing belt 13. This structure effectively addresses the loosening caused by prolonged operation or wear of the polishing belt 13, preventing issues such as deviation and slippage, and ensuring stable polishing results.

[0051] To accommodate the space required for the tensioning structure, in the aforementioned triangular arrangement, the drive roller 11 is slightly offset from the geometric center, creating a relatively open area on one side compared to an equilateral or isosceles triangle for accommodating the tensioning roller 15. This offset arrangement effectively provides structural installation space for the tensioning roller 15 without affecting the stability of the polishing path, achieving a balance between overall compactness and functional completeness.

[0052] The tensioning roller 15 and the elastic component 16 work together to form an adaptive tension adjustment system, which not only improves the operational stability of the polishing mechanism 1, but also enhances the adaptability of the polishing equipment 100 to different workpiece sizes and shapes, making it particularly suitable for polishing irregularly shaped and complex structural parts.

[0053] The water jet mechanism 2 is set on both sides of the polishing belt 13, and multiple nozzles 21 are symmetrically arranged along its length. It can continuously rinse and cool the surface of the workpiece during the polishing process, and promptly remove the dust and heat generated during the polishing process. On the one hand, it avoids the accumulation that causes a decrease in polishing accuracy, and on the other hand, it can prevent the workpiece from overheating, improve the surface yield and overall processing quality.

[0054] In summary, the polishing equipment 100 provided in this embodiment has the advantages of stable operation, strong adaptability, good polishing effect, and strong cleaning and cooling coordinated operation capability. It is particularly suitable for batch and efficient polishing of metal or polymer parts with complex shapes and high precision requirements.

[0055] Furthermore, it also includes a vertically arranged mounting plate 3 for mounting the polishing mechanism 1; the elastic component 16 includes an elastic element 161 and an eccentric wheel 162 rotatably arranged on the mounting plate 3, one end of the elastic element 161 is connected to the mounting plate 3 and the other end is connected to the eccentric wheel 162; the tensioning roller 15 is fixed on the eccentric wheel 162.

[0056] In this embodiment, to improve the overall assemblability and structural stability of the polishing mechanism 1, a vertical mounting plate 3 is provided to support multiple core structural components such as the active roller 11, the driven roller 12, and the tensioning roller 15. All components are concentrated on the same side surface of the mounting plate 3, which helps to form a modular unit with a clear structure and convenient assembly, and also provides a unified reference surface for subsequent motion driving and position adjustment.

[0057] The tension roller 15 is installed and its motion controlled via an adjustable structure using an eccentric wheel 162. The eccentric wheel 162 is rotatably mounted on the mounting plate 3, and the tension roller 15 is fixedly mounted on it, allowing for slight displacement adjustment as the eccentric wheel 162 rotates. A spring-like elastic element 161, located between the mounting plate 3 and the eccentric wheel 162, continuously applies a restoring force to the polishing belt 13, ensuring that the tension roller 15 remains in contact with the running surface of the polishing belt 13. This forms a tensioning structure with a self-resetting function, providing basic support and ensuring dynamic adjustment during operation, effectively improving the stability and tension consistency of the polishing belt 13 during long-term operation. Compared to a simple spring-driven structure, the introduction of the eccentric wheel 162 structure allows for a larger stroke range and a smoother mechanical curve, while also offering good spatial adaptability and reliability, resulting in greater stability and durability in complex or long-term operating environments.

[0058] Furthermore, the water jet mechanism 2 is fixed to the lower part of the mounting plate 3 by the support frame 4, and the lower end of the mounting plate 3 is provided with an avoidance hole 31 corresponding to the nozzle 21;

[0059] The support frame 4 has two guide rods 41 arranged in parallel with the mounting plate 3. The two guide rods 41 are used to install multiple nozzles 21.

[0060] In this embodiment, the water jet mechanism 2 is installed on the lower part of the mounting plate 3 via the support frame 4. Structurally, it is close to the running surface of the polishing belt 13, which is conducive to the fixed-point rinsing of the front and rear sides of the polishing station. In order to facilitate the arrangement and improve stability, the support frame 4 is provided with two guide rods 41 extending along the direction of the polishing belt 13. The two guide rods 41 are respectively located on the front and rear sides of the polishing belt 13 and are parallel to the direction of the polishing belt 13. Multiple nozzles 21 are symmetrically fixed on the two guide rods 41 to form a uniform and continuous water flow coverage area.

[0061] Considering the spatial interference between the water jet mechanism 2 and the mounting plate 3, an avoidance hole 31 is provided at the lower end of the mounting plate 3, which is opened in the area where the nozzles 21 are arranged, so as to facilitate the installation of the water jet mechanism 2.

[0062] This structure enables coaxial collaborative polishing and cleaning operations, and forms a rigid support network through the mounting plate 3 and guide rod 41. The nozzles 21 are neatly arranged, ensuring consistent spray angles and facilitating later maintenance and replacement.

[0063] Furthermore, it also includes a workpiece loading shaft 51 for placing workpieces, the workpiece loading shaft 51 being disposed below the polishing belt 13, and two guide rods 41 being disposed parallel to each other on both sides of the workpiece loading shaft 51.

[0064] The workpiece loading shaft 51 is positioned below the polishing belt 13. The portion of the polishing belt 13 located between the two driven rollers 12 forms a polishing station, and the workpiece loading shaft 51 is positioned directly below the polishing station, facilitating vertical contact and full contact between the polishing belt 13 and the workpiece. Simultaneously, two guide rods 41 are arranged along the front-rear direction of the workpiece loading shaft 51, with the two guide rods 41 arranged parallel to each other on both sides of the workpiece loading shaft 51. These guide rods support and mount multiple nozzles 21 in the water jet mechanism 2, enabling simultaneous cleaning of the front and rear surfaces of the workpiece.

[0065] Furthermore, it also includes a loading and unloading mechanism 5, which includes a turntable platform 52 and a second drive motor 53 for driving the turntable platform 52 to rotate;

[0066] There are two workpiece loading shafts 51, which are symmetrically arranged on both sides of the turntable platform 52; the turntable platform 52 is used to drive the two workpiece loading shafts 51 to rotate and exchange positions with each other.

[0067] The turntable platform 52 achieves the alternating switching of the two workpiece loading shafts 51 to the polishing station through rotation. That is, while polishing is being performed at one end, manual or robotic loading and unloading operations can be completed at the other end, thereby significantly improving the overall operating efficiency and automation level of the machine. It is particularly suitable for batch continuous processing tasks, effectively reducing waiting and interruption time, and realizing the parallel execution of polishing and loading actions.

[0068] In this embodiment, the workpiece loading shaft 51 is designed with a slender structure to arrange multiple workpieces to be polished at intervals along the axial direction. Together with the polishing belt 13 surrounding the driving roller 11 and the two driven rollers 12, multiple workpieces can be polished simultaneously in the same operating cycle, thereby significantly improving the overall polishing efficiency and production capacity.

[0069] Compared to the traditional single-station, piece-by-piece polishing method, this structure can improve efficiency, enable parallel operation of multiple workpieces, and effectively shorten the processing cycle of a single piece; reduce costs by reducing the frequency of workpiece changes and the need for manual intervention.

[0070] Furthermore, the turntable platform 52 is provided with a bearing seat 521 that corresponds one-to-one with the workpiece loading shaft 51;

[0071] The bearing seat 521 has two opposing mounting seats 5211 at each end corresponding to the workpiece loading shaft 51; the workpiece loading shaft 51 is detachably connected to the bearing seat 521 through the two mounting seats 5211.

[0072] To enable quick replacement and convenient installation of the workpiece loading shaft 51, the turntable platform 52 is equipped with shaft seats 521 that correspond one-to-one with the workpiece loading shaft 51. Each shaft seat 521 has two oppositely arranged mounting seats 5211 at both ends, and the workpiece loading shaft 51 is detachably connected to the mounting seats 5211 through its two ends. This connection structure ensures stable support for the workpiece loading shaft 51 during operation and facilitates quick disassembly and reassembly when changing different types of workpieces or during maintenance.

[0073] Furthermore, the mounting base 5211 has a mounting groove a corresponding to the end of the workpiece loading shaft 51, and a cover plate b is provided on the mounting base 5211; the cover plate b is used to cover the mounting groove a and fix the workpiece loading shaft 51 in the mounting groove a.

[0074] One end of the cover plate b is rotatably connected to the mounting base 5211, and the other end extends toward the mounting base 5211 with a locking block c. The mounting base 5211 is provided with a slot d that cooperates with the locking block c.

[0075] To improve the positioning and fixing performance and ease of loading and unloading of the workpiece loading shaft 51 in the mounting base 5211, this embodiment further includes an openable cover plate b structure: the mounting base 5211 has a mounting groove a corresponding to the end of the workpiece loading shaft 51 for the workpiece loading shaft 51 to be inserted; above the mounting groove a, a rotatable cover plate b is provided to securely press the workpiece loading shaft 51 into the mounting groove a; specifically, one end of the cover plate b is rotatably connected to the mounting base 5211 via a hinge structure, and the other end extends toward the mounting base 5211 with a locking block c, and the mounting base 5211 is correspondingly provided with a locking groove d that cooperates with the locking block c. When the cover plate b is flipped closed, the locking block c inserts into the locking groove d to form a reliable lock, preventing the workpiece loading shaft 51 from loosening during polishing or rotation; this structure not only allows for quick fixing and disassembly of the shaft, but its single-sided opening and closing method facilitates manual operation and automated execution. Combined with the turntable platform 52 structure, it can effectively improve the safety and efficiency of the loading and unloading process.

[0076] To improve the ease of loading and unloading and the reliability of fixing the workpiece loading shaft 51, a quick-opening and closing snap-fit ​​structure is also provided between the mounting base 5211 and the cover plate b in this embodiment, as follows: a barbed snap-fit ​​button f is provided inside the slot d, that is, a snap-fit ​​spring that can be elastically deformed is added at the position of the slot d (not shown in the figure), the front end of the snap-fit ​​spring is provided with a barbed part that engages with the snap-fit ​​block c (not shown in the figure), and a pressable release button is connected to the middle of the snap-fit ​​spring.

[0077] During the closing process of cover plate b, locking block c pushes the retaining spring to undergo elastic deformation. When locking block c is fully inserted into the retaining groove d, the retaining spring returns to its original deformation, and the barb automatically engages with the lower edge of locking block c, achieving automatic locking. When it is necessary to open cover plate b, the operator can press the release button to disengage the barb from locking block c, enabling quick opening and improving loading and unloading efficiency and ease of operation. This locking structure is simple in design, highly reliable, and features tool-free quick clamping and disassembly, making it particularly suitable for polishing applications where workpieces are frequently changed.

[0078] Furthermore, the mounting base 5211 is also provided with a support member e located below the workpiece loading shaft 51. The end of the support member e near the workpiece loading shaft 51 is provided with a guide slope g. The guide slope g is inclined downward along the outer side and is used to support the workpiece on the workpiece loading shaft 51 from the bottom.

[0079] The support component e is a block-shaped component. A guide slope g that slopes downward along the outer side is provided at one end near the workpiece loading shaft 51. This is used to support and limit the bottom of the workpiece to prevent it from sagging or shifting under the action of gravity or water pressure. In addition, the outward-sloping design of the guide slope g also facilitates the discharge of water flow and polishing debris to the outside during the processing, playing a role in natural flow guidance and cleaning assistance, and preventing the accumulation of foreign matter from affecting the stability of loading and polishing.

[0080] Furthermore, the polishing mechanism 1 also includes a lifting motion component 6 and a horizontal motion component 7. The lifting motion component 6 is used to drive the mounting plate 3 to move up and down in the vertical direction, and the horizontal motion component 7 is used to drive the lifting motion component 6 to move in the horizontal direction.

[0081] Mounting plate 3 is fixed to lifting motion component 6, and lifting motion component 6 is fixed to horizontal motion component 7.

[0082] This embodiment includes a lifting motion component 6 and a horizontal motion component 7, used to adjust the spatial position of the polishing mechanism 1 during processing. The lifting motion component 6 moves vertically up and down to adjust the relative height between the polishing belt 13 and the workpiece surface, adapting to workpieces of different sizes or surface contours. The horizontal motion component 7 performs overall lateral movement, allowing the entire polishing mechanism 1 to be finely adjusted along the axial or lateral position of the workpiece, improving processing accuracy and flexibility. The combination of the two components enables three-dimensional displacement of the polishing structure, which not only improves the overall adaptability of the equipment but also facilitates system debugging and dynamic obstacle avoidance.

[0083] The lifting motion component 6 includes a motor and a gear and rack mechanism. The motor drives the gear to rotate through the output shaft. The gear meshes with a vertical rack on one side of the mounting plate 3, thereby achieving stable lifting and lowering displacement of the mounting plate 3. This structure has the advantages of smooth transmission, strong load-bearing capacity, and high controllability, and is suitable for height adaptation adjustment in the processing of irregularly shaped workpieces.

[0084] The horizontal motion component 7 adopts a slide rail and slider configuration. The slide rail is fixed to the main frame structure, and the lifting motion component 6 is mounted on the slider via connecting parts. This structure enables low-friction, high-precision horizontal guiding movement, adapts to the multi-angle processing requirements of workpieces of different sizes, and improves the overall machine's space adjustability and processing flexibility.

[0085] Furthermore, it also includes a main housing 88, which covers the polishing mechanism 1, the water jet mechanism 2 and the loading and unloading mechanism 5; the main housing 88 has a loading and unloading window 81 corresponding to the workpiece loading shaft 51.

[0086] To ensure overall machine safety and on-site cleanliness, this embodiment also includes a cover structure, namely the main housing 88. The main housing 88 completely covers the polishing mechanism 1, the water jet mechanism 2, and the loading / unloading mechanism 5, isolating the working area from the external environment and preventing water mist, debris, or dust from spilling out. On the side of the main housing 88 away from the polishing station, there is a loading / unloading window 81 corresponding to the position of the workpiece loading shaft 51, which facilitates manual or robotic arm loading / unloading operations while ensuring the integrity of the outer shell and the airtightness of the processing area. The main housing 88 not only improves operational safety and cleanliness but also facilitates modular packaging and appearance optimization of the equipment, making it suitable for integrated use in automated production lines in workshops.

Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here.
