Description

Technical Field

[0001] This application relates to the field of surface treatment equipment for precision parts, and in particular to a horizontal tumbling polishing machine for watch movement parts. Background Technology

[0002] In the field of precision parts surface treatment equipment technology, tumbling shot blasting machines and other tumbling polishing equipment play a crucial role in deburring and surface finishing of parts. As a precision timekeeping instrument, watches have movement components characterized by their tiny size, complex structure, and extremely high precision requirements (micrometer level). Surface burrs directly affect the assembly accuracy, smoothness of movement, and lifespan of the watch movement. The quality of watch movement components directly impacts the watch's performance and lifespan; therefore, the precision requirements for tumbling polishing deburring are extremely stringent.

[0003] Currently, tumbling polishing equipment is mainly of vertical structure, with some horizontal tumbling polishing machines also used for processing conventional parts. For tumbling polishing and deburring of watch movement parts, the common methods are: vertical tumbling polishing machines rely on the collision of the material's own gravity and rotational force, removing burrs through mutual friction between the materials; existing horizontal tumbling polishing machines are mostly single-barrel or multi-barrel integrated designs, relying on the circumferential rolling of the rollers to tumble the material, achieving deburring and surface finishing.

[0004] However, the aforementioned techniques have significant limitations in processing complex watch movement components. Due to the small size and light weight of watch movement parts, vertical tumbling polishing machines are prone to uneven mixing and insufficient impact force, resulting in incomplete burr removal and inconsistent surface finish. Existing horizontal tumbling polishing machines lack an independent rotation structure, achieving only a single, integral circular rolling motion, failing to create a complex motion trajectory and resulting in insufficient material tumbling, making it difficult to meet the processing requirements of complex components. Summary of the Invention

[0005] In order to improve the surface finish of parts, this application provides a horizontal tumbling polishing machine for watch movement parts.

[0006] The horizontal tumbling polishing machine for watch movement parts provided in this application adopts the following technical solution: A horizontal tumbling polishing machine for watch movement parts includes: a support mechanism; a drive mechanism mounted on the support mechanism; a main rotating mechanism mounted on the support mechanism, a first end of the main rotating mechanism being drively connected to the output end of the drive mechanism, the main rotating mechanism having multiple second ends distributed circumferentially around the axis of the first end of the main rotating mechanism, the drive mechanism driving the first end of the main rotating mechanism to rotate, causing the multiple second ends of the main rotating mechanism to revolve around the axis of the first end of the main rotating mechanism; and multiple roller mechanisms. The roller mechanism is correspondingly arranged with the second end of the main rotating mechanism. The roller mechanism is coaxial with the second end of the corresponding main rotating mechanism and is rotatably connected to the second end of the corresponding main rotating mechanism. The roller mechanism is used to roll and polish the workpiece to be processed. A transmission mechanism is provided, with multiple transmission mechanisms corresponding to the roller mechanism. The first end of the transmission mechanism is connected to the main rotating mechanism, and the second end of the transmission mechanism is connected to the corresponding roller mechanism. The transmission mechanism is used to enable the revolution of the second end of the main rotating mechanism to drive the roller mechanism to rotate around its own axis.

[0007] By adopting the above technical solution, the support mechanism provides support for the entire horizontal tumbling polishing machine, ensuring stable placement and operation of the equipment. The drive mechanism is mounted on the support mechanism, providing power for the operation of the equipment. The main rotating mechanism is mounted on the support mechanism, with its first end connected to the output end of the drive mechanism. Driven by the drive mechanism, the first end of the main rotating mechanism rotates, causing multiple second ends of the main rotating mechanism to revolve around the axis of the first end, thus realizing the function of driving multiple roller mechanisms to revolve. Multiple roller mechanisms are correspondingly arranged with the second ends of the main rotating mechanism and coaxially rotatably connected, used for tumbling polishing the watch movement parts to be processed. The transmission mechanism connects the main rotating mechanism and the roller mechanisms, enabling the revolve of the second ends of the main rotating mechanism to drive the roller mechanisms to rotate around their own axes. This allows the parts to be processed within the roller mechanisms to form a composite motion trajectory, achieving multiple orderly and sufficient collisions, resulting in more thorough deburring of the watch movement parts, a more consistent surface finish, improved surface processing quality, and enhanced tumbling polishing effect and mass production efficiency.

[0008] Optionally, the main rotating mechanism includes a bracket, a rotating shaft, and a mounting bracket. The bracket is mounted on the support mechanism, and the rotating shaft is rotatably connected to the bracket. The driving mechanism includes a driving component, a first main drive wheel, a second main drive wheel, and a main drive component. The driving component is mounted on the support mechanism. The first main drive wheel is located at the output end of the driving component, and the second main drive wheel is located at the first end of the rotating shaft. The main drive component is wound around the first main drive wheel and the second main drive wheel, enabling the driving mechanism to drive the first end of the main rotating mechanism to rotate. The mounting bracket has multiple mounting ends, forming the second end of the main rotating mechanism. The middle part of the mounting bracket is connected to the second end of the rotating shaft, and the multiple mounting ends are distributed circumferentially along the axis of the rotating shaft.

[0009] By adopting the above technical solution, the bracket is mounted on the support mechanism to provide support for the rotating shaft, enabling the rotating shaft to rotate stably and be connected to the bracket. The drive component is mounted on the support mechanism. When the drive component operates, its output end drives the first main drive wheel to rotate. The first main drive wheel drives the second main drive wheel to rotate through the main drive component, thereby causing the rotating shaft to rotate, realizing that the drive mechanism drives the first end of the main rotating mechanism to rotate. The middle part of the mounting frame is connected to the second end of the rotating shaft. Multiple mounting ends are provided on it and distributed around the axis of the rotating shaft. As the rotating shaft rotates, the mounting ends can drive the components connected to them to revolve around the axis of the rotating shaft, so that the entire main rotating mechanism can operate in the designed manner to meet the working requirements of the tumbler.

[0010] Optionally, the transmission mechanism includes a first sub-transmission wheel, a second sub-transmission wheel, and a sub-transmission component. The first sub-transmission wheel is fixedly connected to the bracket and is coaxially arranged with the rotating shaft. The second sub-transmission wheel is located at the first end of the corresponding roller mechanism and is correspondingly arranged with the first sub-transmission wheel. The sub-transmission component is wound around the first sub-transmission wheel and the second sub-transmission wheel. When the driving mechanism drives the roller mechanism to revolve circumferentially around the rotating shaft axis, the sub-transmission component drives the roller mechanism to rotate around its own axis through the second sub-transmission wheel.

[0011] By adopting the above technical solution, the first sub-drive wheel is fixedly connected to the bracket and coaxially arranged with the rotating shaft, providing a stable reference and support for transmission; the second sub-drive wheel is located at the first end of the corresponding roller mechanism, corresponding to the first sub-drive wheel, and can receive the power transmitted by the first sub-drive wheel; the sub-drive component is wound around the first and second sub-drive wheels, playing the role of transmitting power. When the drive mechanism drives the roller mechanism to revolve around the rotating shaft axis, the second sub-drive wheel revolves around the first sub-drive wheel. The sub-drive component can, through the drive of the second sub-drive wheel, make the roller mechanism rotate around its own axis, so that the roller mechanism forms a compound motion trajectory, allowing the watch movement components inside the roller to achieve multiple orderly and sufficient drop-type collisions, thereby making deburring more thorough, surface smoothness more consistent, and improving the tumbling and polishing effect.

[0012] Optionally, the diameters of the first sub-drive wheel and the second sub-drive wheel are different.

[0013] By adopting the above technical solution, the first and second transmission wheels have different diameters, resulting in different linear velocities and speed ratios during transmission. When the main rotating mechanism drives the roller mechanism to revolve, this different diameter design allows the rotational speed of the roller mechanism around its own axis, driven by the second transmission wheel, to differ from the revolution speed. This causes the watch movement components within the roller mechanism to form more complex motion trajectories, achieving more thorough tumbling and collision, thereby improving the polishing effect, resulting in more thorough burr removal, more consistent surface finish, and meeting the high-difficulty processing requirements of watch movement components.

[0014] Optionally, the roller mechanism includes a support shaft, a mounting box, a feeding barrel, a barrel cover, and a locking assembly. The support shaft is rotatably connected to the mounting end, and both ends of the support shaft extend beyond the mounting end. The first end of the support shaft is connected to the second sub-drive wheel. The bottom of the hollow mounting box is connected to the second end of the support shaft. The mounting box has an opening at one end away from the support shaft. The first end of the feeding barrel is installed in the mounting box through the opening. The second end of the feeding barrel away from the support shaft has a feeding port. The barrel cover is detachably connected to the feeding port. The locking assembly is located on the mounting box and is used to selectively abut against the barrel cover to selectively close the feeding port and fix the feeding barrel relative to the mounting box. The feeding barrel is hollow and is used to hold the workpiece to be processed.

[0015] By adopting the above technical solution, the support shaft is rotatably connected to the mounting end and extends at both ends. Its first end is connected to the second transmission wheel, which can transmit the power of the transmission mechanism to the roller mechanism, causing the roller mechanism to rotate around its own axis. The bottom of the hollow and sealed mounting box is connected to the second end of the support shaft, providing installation space and support for the feeding barrel, so that the feeding barrel can rotate and revolve stably. The feeding barrel is installed in the mounting box through the opening. Its hollow interior can hold the workpiece to be processed. During the rotation and revolution, the workpiece to be processed can fully collide and rub with the grinding media to achieve deburring and surface finishing. The barrel cover is detachably connected to the feeding port, which is convenient for putting in and taking out the workpiece to be processed. The locking component is located on the mounting box and can selectively abut against the barrel cover to close the feeding port, ensuring that the barrel cover, the feeding barrel and the mounting box are relatively fixed, preventing the workpiece to be processed from falling during the tumbling process, and improving the safety and stability of the processing.

[0016] Optionally, both the mounting box and the feeding hopper have hexagonal cross-sections.

[0017] By adopting the above technical solution, the hexagonal cross-section mounting box is compatible with the feeding barrel, providing a stable mounting space for the feeding barrel and ensuring its stability within the mounting box. Simultaneously, the hexagonal cross-section of the feeding barrel guides the watch movement components to be processed, creating an orderly drop-type collision. This allows for multiple, orderly, and sufficient drop-type collisions of complex watch movement components, resulting in thorough deburring and consistent surface finish, fully meeting the requirements for movement assembly.

[0018] Optionally, the locking assembly includes a first mounting member, a second mounting member, a limiting member, and a latch. The latch includes a slot and a fastening member. The first mounting member and the second mounting member are respectively disposed on both sides of the outer periphery of the mounting box. The first end of the limiting member is rotatably connected to the first mounting member. The slot is disposed at the second end of the limiting member. The fastening member is connected to the second mounting member. The fastening member is used to selectively connect with the slot to fix the limiting member, so that the middle part of the limiting member is used to press against the bucket lid.

[0019] By adopting the above technical solution, the first and second mounting components are respectively located on both sides of the outer periphery of the mounting box, serving to determine the installation position. The first end of the limiting component is rotatably connected to the first mounting component, ensuring that the limiting component can rotate flexibly and is easy to adjust its position. The slot component is located at the second end of the limiting component, providing a connection point for the fastening component. The fastening component connects to the second mounting component and is used for selective connection with the slot component, which can fix the limiting component, thereby making the middle of the limiting component press tightly against the barrel lid, ensuring that the barrel lid seals the feeding port, and fixing the feeding barrel and mounting box relatively, preventing the barrel lid from loosening or falling off during the rolling and tumbling process, which could lead to the spillage of the workpiece, thus improving the safety and stability of the equipment.

[0020] Optionally, the fastening component includes a fixing part, an mounting part, a rotating part, and a locking part. The fixing part is fixedly connected to the second mounting component. The connecting end of the mounting part is rotatably connected to the fixing part. The actuating end of the mounting part is used to drive the mounting part to rotate around the connecting end. The rotating part is rotatably connected to the mounting part. Both ends of the rotating part extend out of the mounting part. Along the length direction of the mounting part, the rotating part is located between the end of the connecting end and the end of the actuating end. The locking part is U-shaped. Both ends of the locking part are respectively located on both sides of the length direction of the mounting part and are respectively connected to the two ends of the rotating part. The middle part of the locking part is used to selectively connect to the slot component. The actuating end of the mounting part is provided with a connecting groove. The locking assembly also includes an elastic element. Both ends of the elastic element are connected to both sides of the second mounting component, and both ends of the elastic element are symmetrically located on both sides of the length direction of the rotating part. The middle part of the elastic element is used to selectively connect to the connecting groove to restrict the fastening component from disengaging from the slot component.

[0021] By adopting the above technical solution, the fixing part is fixedly connected to the second mounting part, providing a stable installation base for the fastening part; the connecting end of the mounting part is rotatably connected to the fixing part, and its lever end can drive the mounting part to rotate around the connecting end, realizing the operational flexibility of the fastening part; the rotating part is rotatably connected to the mounting part, and both ends extend out of the mounting part, and are located between the end of the connecting end and the end of the lever end along the length direction of the mounting part, providing support for the connection and rotation of the locking part; the two ends of the U-shaped locking part are connected to the two ends of the rotating part, and the middle part is used to selectively connect to the slot part to realize the fixation of the limiting part, thereby making the middle part of the limiting part press against the barrel cover; the connecting groove of the lever end of the mounting part cooperates with the elastic part, the two ends of the elastic part are connected to both sides of the second mounting part and are symmetrically located on both sides of the length direction of the rotating part, and the middle part of the elastic part is selectively connected to the connecting groove, which can restrict the fastening part from being disengaged from the slot part, ensuring that the barrel cover is firmly closed during the rolling polishing process, avoiding the spillage and damage of the watch movement parts to be processed, and improving the safety and reliability of the equipment operation.

[0022] Optionally, the driving mechanism includes a carrier and an adjusting member. The driving member is disposed on the carrier, and the first end of the carrier is rotatably connected to the support mechanism. The adjusting member is disposed at the second end of the carrier and is used to adjust the height of the second end of the carrier, so that the center distance between the first main drive wheel and the second main drive wheel is adjustable, and is used to tension the main drive.

[0023] By adopting the above technical solution, the driving component is mounted on the carrier component, and the first end of the carrier component is rotatably connected to the support mechanism, allowing the carrier component to rotate around this rotatable connection point. An adjusting component is located at the second end of the carrier component, allowing adjustment of its height, thereby changing the center distance between the first and second main drive wheels. When the adjusting component adjusts the height of the second end of the carrier component, the position of the first main drive wheel changes, thus altering the distance between the two main drive wheels and achieving tension on the main drive component. This adjustable center distance design ensures that the main drive component is always in a suitable tension state, avoiding problems such as reduced power transmission efficiency and slippage caused by slack in the drive component. This ensures that the driving mechanism can stably transmit power to the main rotating mechanism, improving the stability and reliability of the equipment operation.

[0024] Optionally, it also includes a control mechanism, which is disposed on the support mechanism and electrically connected to the drive mechanism.

[0025] By adopting the above technical solution, the control mechanism is mounted on the support mechanism, ensuring stable support. The control mechanism is electrically connected to the drive mechanism, allowing for precise control of its operation. For example, it can precisely adjust parameters such as the drive mechanism's rotational speed, start and stop times, thereby accurately controlling the revolution speed of the main rotating mechanism and the rotation speed of the roller mechanism. This ensures the polishing process proceeds according to preset requirements, improving the polishing accuracy and batch consistency of watch movement components, and meeting the processing needs of different watch movement parts.

[0026] In summary, this application includes at least the following beneficial technical effects: The support mechanism provides support for the entire horizontal tumbling polishing machine, ensuring stable placement and operation. The drive mechanism, mounted on the support mechanism, provides power for the machine's operation. The main rotating mechanism, also mounted on the support mechanism, has its first end connected to the output end of the drive mechanism. Driven by the drive mechanism, the first end of the main rotating mechanism rotates, causing multiple second ends of the main rotating mechanism to revolve around the axis of the first end, thus driving multiple roller mechanisms to revolve. Multiple roller mechanisms are correspondingly arranged and coaxially connected to the second ends of the main rotating mechanism, used for tumbling and polishing watch movement components. The transmission mechanism connects the main rotating mechanism and the roller mechanisms, enabling the revolve of the second ends of the main rotating mechanism to drive the roller mechanisms to rotate around their own axes. This creates a complex motion trajectory for the components within the roller mechanisms, resulting in multiple, orderly, and thorough collisions. This leads to more thorough deburring of the watch movement components, a more consistent surface finish, improved surface processing quality, and enhanced tumbling polishing effect and mass production efficiency.

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0042] like Figure 1 and Figure 2As shown in the illustration, this application discloses a horizontal tumbling polishing machine (hereinafter referred to as "tumbling polishing machine") for watch movement parts. The tumbling polishing machine includes a support mechanism 1, a drive mechanism 2, a main rotation mechanism 3, a transmission mechanism 5, and multiple roller mechanisms 4. It employs a multi-layered transmission structure to achieve a combined revolution and rotation motion of the rollers, ensuring sufficient collision of watch movement parts during tumbling polishing, thus improving deburring effect and efficiency. This tumbling polishing machine is suitable for tumbling polishing and deburring, and surface finishing of high-difficulty, high-precision parts such as gears, shafts, rod springs, and plates in watch movements. It can be widely used in production workshops and precision machining laboratories in industries with extremely high requirements for surface quality and dimensional accuracy, such as high-end watch manufacturing and precision instrument parts processing.

[0043] The drive mechanism 2 is mounted on the support mechanism 1 and provides power to the main rotating mechanism 3. The main rotating mechanism 3 is mounted on the support mechanism 1, and its first end is connected to the output end of the drive mechanism 2. The main rotating mechanism 3 has multiple second ends evenly distributed around the axis of the first end. The drive mechanism 2 drives the first end of the main rotating mechanism 3 to rotate, allowing the multiple second ends of the main rotating mechanism 3 to revolve around the axis of the first end of the main rotating mechanism 3. The roller mechanism 4 is arranged one-to-one with the second ends of the main rotating mechanism 3 and is connected to the corresponding second ends of the main rotating mechanism 3. The two ends are coaxial and rotatably connected to the second end of the corresponding main rotating mechanism 3. The axis of the roller mechanism 4 extends horizontally and is used to roll and polish the workpiece to be processed. There are also multiple transmission mechanisms 5, which are set in correspondence with the roller mechanism 4. The first end of the transmission mechanism 5 is connected to the main rotating mechanism 3 and the second end is connected to the corresponding roller mechanism 4. The revolution of the second end of the main rotating mechanism 3 can drive the roller mechanism 4 to rotate around its own axis. In this way, the roller mechanism 4 can realize the compound motion of revolution and rotation, which greatly enhances the stirring and collision effect on the material, thereby significantly improving the deburring effect of the core parts.

[0044] like Figure 1 and Figure 2As shown, specifically, the support mechanism 1 includes a support frame 11, a support plate 12, and several feet 13. The support frame 11 can be integrally welded from high-strength alloy steel plates to improve support stability. The support plate 12 is mounted on the support frame 11, and the drive mechanism 2 and the main rotation mechanism 3 are both mounted on the support plate 12. Several adjustable feet 13 are distributed at the lower end of the support frame 11. The feet 13 can be vibration-damping feet, which have good vibration damping effect, effectively reducing the vibration generated during equipment operation, ensuring the stability of equipment operation, and also helping to extend the service life of the equipment. In addition, the support mechanism 1 also includes baffles 14 and doors 15. There are two sets of baffles 14 and two sets of doors 15, which are arranged opposite each other. The baffles 14 and doors 15 form a rectangular frame structure. The doors 15 can be selectively opened to facilitate operators to perform loading and unloading operations. The control mechanism 6 is mounted on the baffles 14, which facilitates operation and observation by the operators. One end of the door 15 is rotatably connected to the support frame 11, and the other end is selectively connected to the support frame 11 via a latch 454. To open the door 15, the latch 454 is released; to close the door 15, the latch 454 is engaged, and the door 15 closes securely. It is understood that the latch 454 can be an existing structure. Specifically, the high-strength alloy steel plate of the support plate 12 is 4mm thick, the support frame 11 is made of 8mm thick high-strength alloy steel, and the rubber damping pads of the shock-absorbing feet have a Shore hardness of A50-A60, ensuring structural strength and shock absorption effect.

[0045] like Figure 3 and Figure 4 As shown, specifically, the main rotating mechanism 3 includes a bracket 31, a rotating shaft 32, and a mounting bracket 33. The bracket 31 is stably mounted on the support plate 12, providing stable support for the entire main rotating mechanism 3. The bracket 31 can be made of high-strength alloy steel, such as carbon steel, which has a robust structure and good resistance to deformation. The rotating shaft 32 is rotatably connected to the bracket 31 via bearings. This connection method makes the rotation of the shaft 32 smoother and effectively reduces friction and energy loss. Deep groove ball bearings can be selected, which have high rotational accuracy and low noise characteristics.

[0046] The mounting bracket 33 has multiple mounting ends 331, which form the second end of the main rotating mechanism 3. The middle of the mounting bracket 33 is connected to the second end of the rotating shaft 32. The multiple mounting ends 331 are evenly distributed around the axis of the rotating shaft 32, so that when the rotating shaft 32 rotates, the mounting ends 331 can make a smooth revolution around the axis of the rotating shaft 32. This layout makes the force on each mounting end 331 more even, ensuring the stable operation of the entire main rotating mechanism 3. The mounting ends 331 can be in the form of a sleeve structure to facilitate rotational connection.

[0047] like Figure 3, Figure 4 and Figure 5 As shown, the drive mechanism 2 includes a drive element 21, a first main drive wheel 22, a second main drive wheel 23, and a main drive element 24. The drive element 21, for example, is an electric motor, securely mounted on the support mechanism 1. The first main drive wheel 22 is mounted at the output end of the drive element 21, and the second main drive wheel 23 is mounted at the first end of the rotating shaft 32. The main drive element 24 is wound around the first main drive wheel 22 and the second main drive wheel 23. When the drive element 21 operates, it drives the first main drive wheel 22 to rotate, which in turn drives the second main drive wheel 23 to rotate via the main drive element 24, thereby driving the rotating shaft 32 to rotate. In other embodiments, the first main drive wheel 22 and the second main drive wheel 23 can also be sprockets in a chain drive, and the main drive element 24 is a chain. Chain drives have the advantages of high transmission accuracy and strong load-bearing capacity.

[0048] like Figure 3 , Figure 4 and Figure 6 As shown, specifically, the drive mechanism 2 includes a support member 25 and an adjusting member 26. The drive member 21 is mounted on the support member 25, and the first end of the support member 25 is rotatably connected to the support mechanism 1. The adjusting member 26 is located at the second end of the support member 25, and can adjust the height of the second end of the support member 25, thereby making the center distance between the first main drive wheel 22 and the second main drive wheel 23 adjustable, which is used to tension the main drive member 24. After prolonged use, the main drive member 24 may become loose. In this case, adjusting the height of the support member 25 by adjusting the adjusting member 26 can maintain the main drive member 24 with appropriate tension, ensuring the normal transmission of the drive mechanism 2.

[0049] like Figure 3 , Figure 6 and Figure 7 As shown, the adjusting component 26 can be a screw and nut adjusting structure. By rotating the screw, the nut moves on the screw, thereby changing the height of the bearing component 25. This adjustment method is simple, reliable, and easy to operate.

[0050] like Figure 3 , Figure 8 and Figure 9As shown, specifically, the transmission mechanism 5 includes a first sub-transmission wheel 51, a second sub-transmission wheel 52, and a sub-transmission component 53. The first sub-transmission wheel 51 is fixedly connected to the bracket 31 and coaxially arranged with the rotating shaft 32. Multiple first sub-transmission wheels 51 are coaxial with the rotating shaft 32, arranged along the axial direction of the rotating shaft 32 and relatively fixed. The first sub-transmission wheel 51 closest to the bracket 31 is fixedly connected to the bracket 31, and the second end of the rotating shaft 32 passes through the middle of the multiple first sub-transmission wheels 51. The second sub-transmission wheel 52 is fixedly arranged at the first end of the corresponding roller mechanism 4, corresponding to the first sub-transmission wheel 51. The sub-transmission component 53 is wound around the first sub-transmission wheel 51 and the second sub-transmission wheel 52. When the drive mechanism 2 drives the roller mechanism 4 to revolve around the axis of the rotating shaft 32, since the first sub-transmission wheel 51 is fixed, the sub-transmission component 53 will drive the roller mechanism 4 to rotate around its own axis through the second sub-transmission wheel 52 under the action of the first sub-transmission wheel 51, realizing the compound motion of "rotation + revolving around the center point in a circle" and optimizing the rolling and polishing effect.

[0051] like Figure 3 , Figure 8 and Figure 10 As shown, the first sub-drive wheel 51 and the second sub-drive wheel 52 have different diameters. This different diameter setting can adjust the rotation speed and torque of the roller mechanism 4 to meet different processing requirements. The specific settings can be adjusted according to the actual situation.

[0052] like Figure 3 and Figure 8 As shown, in this embodiment, the first main drive pulley 22, the second main drive pulley 23, the first sub-drive pulley 51, and the second sub-drive pulley 52 are all pulleys, while the main drive component 24 and the sub-drive component 53 are both belts. Belt drives have advantages such as smooth transmission, low noise, and overload protection, and can meet the transmission requirements of the equipment.

[0053] like Figure 3 , Figure 9 and Figure 11 As shown, specifically, the roller mechanism 4 includes a support shaft 41, a mounting box 42, a feeding bucket 43, a bucket cover 44, and a locking assembly 45. The support shaft 41 is rotatably connected to the mounting end 331 via bearings. Deep groove ball bearings can also be selected to ensure the flexibility and stability of the support shaft 41's rotation. Both ends of the support shaft 41 extend beyond the mounting end 331, with the first end connected to the second sub-drive wheel 52. Thus, when the sub-drive component 53 drives the second sub-drive wheel 52 to rotate, it can drive the support shaft 41 to rotate. In this embodiment, the bearing can be selected according to the need for a suitable bearing housing; the specific type is not limited, but the bearing housing model should be adapted to the equipment's speed requirements to ensure smooth rotation without jamming.

[0054] like Figure 3 , Figure 9 and Figure 12 As shown, the bottom of the hollow mounting box 42 is connected to the second end of the support shaft 41. The end of the mounting box 42 away from the support shaft 41 has an opening 421. The first end of the feeding barrel 43 is installed inside the mounting box 42 through this opening 421, so that the feeding barrel 43 fits inside the mounting box 42. The second end of the feeding barrel 43 away from the support shaft 41 has a feeding port 431. The barrel cover 44 is detachably connected to the feeding port 431. The connection method is not limited, such as a snap-fit ​​connection, which facilitates the placement of the watch movement parts to be processed and the grinding media into the feeding barrel 43.

[0055] like Figure 9 , Figure 11 and Figure 12 As shown, the feeding hopper 43 is a one-piece molded structure. Both the mounting box 42 and the feeding hopper 43 have hexagonal cross-sections. Each feeding hopper 43 has an internal hexagonal cavity design with a side length of 49mm, which guides the material to form an orderly drop-type collision. This hexagonal design makes it easier for the material inside the feeding hopper 43 to form a drop-type collision during the rolling process, increasing the friction and collision opportunities between materials, and improving the deburring and surface finishing effects. The feeding hopper 43 can be made of high-strength nylon material, which has good wear resistance and cushioning properties, and can avoid scratching precision parts. The locking component 45 is set on the mounting box 42 and is used to selectively abut against the hopper lid 44, so that the hopper lid 44 can selectively close the feeding port 431 and fix the feeding hopper 43 to the mounting box 42. In this way, during the rolling and polishing process, the feeding hopper 43 will not detach from the mounting box 42 due to shaking, ensuring the safe operation of the equipment and the processing effect. In this embodiment, the minimum distance between each feeding barrel 43 and the axis of the rotating shaft 32 is the same, ensuring balanced force during revolution. Specifically, the cavity wall thickness of the hexagonal nylon feeding barrel 43 is 3mm, the barrel body is made of high-strength nylon material, the inner wall is smooth and burr-free, and a separator can be placed inside the barrel as needed to separate different types of parts to prevent them from colliding and being damaged. The feeding barrels 43 are of uniform specifications, and the capacity of a single barrel is suitable for the batch processing needs of watch movement parts.

[0056] In other embodiments, the feeding hopper 43 is octagonal in shape, with spirally distributed raised strips on the inner wall of the cavity. This octagonal and spiral raised design optimizes the composite motion trajectory through the cooperation of the polygonal cavity and the spiral raised strips. When the roller mechanism 4 revolves and rotates, the material in the feeding hopper 43 forms a spiral rising and falling motion under the action of the octagonal cavity and the spiral raised strips. This unique motion trajectory increases the chances of collision and friction between materials, further improving the deburring effect. The processing technology is relatively simpler and suitable for some application scenarios with lower processing requirements but certain requirements for deburring effect.

[0057] The octagonal nylon feeding hopper 43 is a one-piece molded structure. The inner wall of the cavity is provided with 2-3 sets of spiral protrusions. The spiral lead is 1 / 2-2 / 3 of the length of the feeding hopper 43, and the protrusion height is 6-10mm. Multiple feeding hoppers 43 are still evenly distributed and installed. In the compound movement, the protrusions cooperate with the cavity to make the material form a spiral upward and downward movement.

[0058] like Figure 9 and Figure 12 As shown, specifically, the locking assembly 45 includes a first mounting member 451, a second mounting member 452, a limiting member 453, and a latch 454. The latch 454 includes a slot 4541 and a fastening member 4542. The first mounting member 451 and the second mounting member 452 are respectively disposed on both sides of the outer periphery of the mounting box 42. The first end of the limiting member 453 is rotatably connected to the first mounting member 451, the slot 4541 is disposed at the second end of the limiting member 453, and the fastening member 4542 is connected to the second mounting member 452. The fastening member 4542 can selectively connect with the slot 4541 to fix the limiting member 453, allowing the protruding center of the limiting member 453 to press against the lid 44. The fastening member 4542 includes a fixing part 45421, a mounting part 45422, a rotating part 45423, and a locking part 45424. The fixing part 45421 is fixedly connected to the second mounting part 452. The connecting end of the mounting part 45422 is rotatably connected to the fixing part 45421. The lever end of the mounting part 45422 can drive the mounting part 45422 to rotate around the connecting end. The rotating part 45423 is rotatably connected to the mounting part 45422. Both ends of the rotating part 45423 extend out from both sides of the mounting part 45422 and are located between the connecting end end and the lever end end along the length direction of the mounting part 45422. The locking part 45424 is U-shaped, with its two ends respectively located on both sides of the length direction of the mounting part 45422 and connected to the two ends of the rotating part 45423. The middle part of the locking part 45424 can be selectively connected to the slot part 4541.

[0059] The actuating end of the mounting part 45422 is provided with a connecting groove 45425. The locking assembly 45 also includes an elastic member 455. The two ends of the elastic member 455 are connected to the two sides of the second mounting part 452, and the two ends are symmetrically arranged on both sides of the rotation part 45423 in the length direction. The middle part of the elastic member 455 can be selectively connected to the connecting groove 45425 to restrict the fastening member 4542 from being disengaged from the slot member 4541.

[0060] like Figure 9 , Figure 11 and Figure 12As shown, when it is necessary to close the feeding hopper 43, first place the hopper lid 44 on the feeding port 431, then rotate the limiting member 453 to engage the locking part 45424 of the locking member 4542 with the locking part 4541. Next, connect the middle part of the elastic member 455 to the connecting groove 45425. This forms a double safety measure, ensuring that the hopper lid 44 will not loosen or fall off during the tumbling process, preventing spillage and damage to parts. It is understood that the latch 454 can use an existing structure made of stainless steel, as long as it fulfills the corresponding function; the elastic member 455 can be a tension spring with an elastic coefficient of 0.5-1 N / mm, ensuring a secure closure and convenient operation, adapting to the vibration and impact during the tumbling process. The tension spring and the latch 454 act relatively independently, providing double protection.

[0061] The elastic element 455 can also be an elastic rubber strip, with the stretching amount of the elastic rubber strip controlled at 5-10mm.

[0062] Figure 1 and Figure 3 As shown, the tumbling polishing machine also includes a control mechanism 6, which is mounted on the support mechanism 1 and electrically connected to the drive mechanism 2. The control mechanism 6 can control the start and stop of the drive mechanism 2, as well as adjust parameters such as the rotation speed of the drive component 21, thereby precisely controlling the revolution and rotation speeds of the drum mechanism 4 and the tumbling polishing time, ensuring processing accuracy and batch consistency. The control mechanism 6 can employ a high-performance microcontroller or programmable logic controller (PLC), along with a display screen and operation buttons, facilitating parameter setting and monitoring by operators.

[0063] Figure 1 and Figure 3As shown, the drive unit 21 can further utilize an AC asynchronous motor with a power of 0.37kW. The control mechanism 6 can also include a frequency converter, a time relay, and an intermediate relay. Through the cooperation of the AC asynchronous motor and the frequency converter, speed regulation is achieved, with a wide speed range and high precision, achieving a speed regulation accuracy of ±1r / min. The time relay, in conjunction with the microcontroller, can precisely control the rolling and polishing time, with an error controlled within ±1r / min, supporting adjustment from 0 to 99 hours. It also supports preset and locked speed parameters to ensure batch processing consistency. The intermediate relay ensures the normal operation of signal transmission and control functions. The control mechanism 6 is equipped with a simple touch panel for intuitive setting, display, and locking of parameters. It is understood that the specific structure and connection relationships of the control mechanism 6 can be set as needed. Given existing technology, details are omitted here; a suitable existing structure can be selected based on requirements. The machine can be equipped with hexagonal nylon feed barrels 43 and grinding media of corresponding specifications, depending on the size and structure of the watch movement parts of different models. The revolution speed can be flexibly adjusted by the frequency converter, and the processing time can be accurately matched by the time relay. There is no need to modify the core structure of the movement, which makes it highly adaptable. The machine is easy to operate, and the parameterized control reduces manual intervention. The simultaneous processing of multiple feed barrels 43 greatly improves production efficiency, taking into account both small-batch customization and large-scale mass production needs. The tumbling polishing machine has been verified in on-site production and has fully achieved the expected results. The amplitude of the machine during operation is ≤0.1mm, the burr residue after processing of parts is ≤0.005mm, and the surface roughness Ra is ≤0.6μm, which fully meets the requirements of movement assembly.

[0064] Figure 1 and Figure 3 As shown, in other embodiments, the drive component 21 can also be a servo motor, which works in conjunction with a frequency converter, and a torque sensor is installed on the output shaft of the necessary reducer. The torque sensor is electrically connected to the control mechanism 6. The servo motor has higher speed regulation accuracy, reaching ±0.5 r / min, and can more accurately control the revolution and rotation speed of the roller mechanism 4 to meet the processing requirements of different watch movement parts. At the same time, the torque sensor can monitor the torque of the reducer output shaft in real time. When the detected torque exceeds the set threshold (e.g., 50-80 N·m), the control mechanism 6 will automatically cut off the motor power and issue an alarm signal. This can avoid equipment overload caused by material jamming in the feeding hopper 43, protect the safety of the equipment and parts in time, and further improve the safety and processing stability of the equipment.

[0065] In another embodiment, the time relay in the control mechanism can be replaced with a PLC. The PLC retains the precise time control module, ensuring that the time error is still controlled within ±1 r / min, guaranteeing accurate control of the tumbling and polishing time. Simultaneously, a parameter storage module is added, allowing for the preset of more than 10 sets of processing parameters, facilitating quick recall by operators based on different parts and processing requirements, thus improving production efficiency. A fault diagnosis and alarm module is also added, capable of identifying motor faults, abnormal speeds, time deviations, and other problems, and promptly issuing alarm signals to remind operators to handle them. Furthermore, the PLC supports integration with the workshop's intelligent system, enabling automatic start-up and shutdown of equipment and data uploading, facilitating information management and production scheduling in the workshop, and adapting to the development trend of intelligent manufacturing. It is understood that the PLC can be selected according to actual needs, utilizing the existing parameter modules; given that this is existing technology, it will not be elaborated upon further here.

[0066] The usage process is as follows: Loading stage: Open the limiting part 453, take out the hexagonal nylon loading barrels 43 one by one, put the high-difficulty parts of the watch movement and the special precision grinding media into the corresponding batches of each loading barrel 43, close the barrel lid 44 of each loading barrel 43, first use the buckle 454 to lock the locking part 45424 into the slot part 4541, and then use the tension spring to tighten the lever end of the buckle 454 to complete the double safety closure of the buckle 454 and tension spring of each loading barrel 43; put each closed loading barrel 43 into the installation box 42 according to the preset position to ensure even distribution, and close the door 15.

[0067] Rolling and polishing stage: Various processing parameters are set through the control mechanism 6, and the rolling and polishing time is preset with the help of the time relay (accuracy ±1r / min). The revolution speed is adjusted through the frequency converter, and the rotation speed of the feeding barrel 43 is adjusted according to the transmission ratio of the transmission mechanism. For example, according to the size of the parts, the circumferential rolling speed, i.e., the revolution speed, is 370r / min, and the rotation speed is 300r / min. After the equipment is started, the drive mechanism 2 drives the roller mechanism 4 to smoothly roll around the axis through the main transmission mechanism. Taking four sets of roller mechanisms 4 as an example, the four sets of belts, which are the sub-transmission components 53, drive the four roller mechanisms 4 to rotate, forming a compound motion trajectory. During the movement of the feeding barrel 43, the internal parts rise along the cavity wall under the guidance of the hexagonal cavity and form multiple drops. The parts and the grinding media fully collide and rub in the compound motion to achieve precise deburring and surface finishing. The shock-absorbing structure such as the shock-absorbing feet can effectively suppress the running vibration, and the nylon material of the feeding barrel 43 further buffers the collision and avoids the parts from bumping.

[0068] Unloading stage: When the time relay reaches the preset rolling and polishing time, the equipment will automatically stop running. After the roller mechanism 4 is completely stationary, the limit piece 453 is opened, and the double safety device on each roller mechanism 4 is unlocked one by one. The barrel cover 44 is opened, and the processed watch movement parts are taken out to complete the whole batch processing cycle. The parts in the four feeding barrels 43 can be processed simultaneously or in batches according to the needs, which improves the production flexibility.

[0069] Understandably, the tumbler also includes necessary structures for connection, support, drive, positioning, limiting, sealing and control functions to enable the tumbler to operate normally; the shape, size, material and quantity of each part of the tumbler can be determined as needed to achieve the corresponding functions.

[0070] The implementation principle of this embodiment is as follows: The horizontal tumbling polishing machine for watch movement parts organically combines the drive mechanism 2, the main rotating mechanism 3, the roller mechanism 4, and the transmission mechanism 5 through a reasonable structural design. The drive mechanism 2 provides power, which drives multiple roller mechanisms 4 to revolve around the axis of the first end of the main rotating mechanism 3 through the main rotating mechanism 3. At the same time, the transmission mechanism 5 makes the roller mechanisms 4 rotate around their own axes, realizing a compound motion. This compound motion allows the watch movement parts in the loading barrel 43 to fully collide and rub, greatly improving the deburring and surface finishing effect. Moreover, the design of each mechanism fully considers the precision machining requirements of watch movement parts, such as shock-absorbing feet to reduce vibration, high-strength nylon loading barrel 43 to avoid scratches, and locking components 45 to ensure safety. This provides reliable equipment support for the precision machining of high-difficulty watch movement parts, can more effectively remove burrs, improve surface finish, ensure machining accuracy and batch consistency, and improve the operational stability and safety of the equipment.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
