[0002] With the rapid development of semiconductor and solar photovoltaic technologies globally, and the continued growth in market demand, the demand for quartz products in related industries is also increasing dramatically. At the same time, these industries are placing higher standards and requirements on the quality and manufacturing processes of quartz products. To meet these high quality standards, the cleanliness of the processing machinery must also reach a higher level. In the actual production and processing of double-sided polishing machines, the gear ring, as a key transmission component, directly affects the subsequent assembly accuracy, operational stability, and service life due to its surface cleanliness.

[0003] However, in current technology, most companies still use manual wiping or air gun blowing to clean the gear rings of double-sided polishing machines. This operation is cumbersome, time-consuming, and makes it difficult to guarantee consistent cleaning quality. Especially for gear rings with complex structures and deep grooves, manual methods are insufficient to completely remove dust, metal shavings, and other impurities, affecting the quality of subsequent processes. Moreover, the cleaning process requires manual intervention, which fails to meet the demands of modern intelligent manufacturing for efficient and automated production.

[0004] Therefore, a well-designed structure is urgently needed to solve the above problems. Utility Model Content

[0029] This utility model discloses an auxiliary tooling for cleaning the gear ring of a double-sided polishing machine, including a fixing mechanism 100 and a cleaning mechanism. The fixing mechanism 100 is fixedly connected to the drive shaft 400 of the polishing machine. The cleaning mechanism includes a connecting unit 200 and a cleaning unit 300. The connecting unit 200 includes a first mounting rod 210 and a second mounting rod 220. The first mounting rod 210 is fixedly connected to the drive shaft 400 through the fixing mechanism 100, and the first mounting rod 210 is distributed circumferentially along the drive shaft 400. The second mounting rod 220 is provided at the end of the first mounting rod 210 away from the drive shaft 400. The axis of the second mounting rod 220 is parallel to the axis of the drive shaft 400. The cleaning unit 300 is installed at the end of the second mounting rod 220 away from the first mounting rod 210.

[0030] like Figures 1 to 3As shown, the auxiliary tooling for cleaning the gear ring of a double-sided polishing machine provided by this utility model is based on the coordinated operation of the fixing mechanism 100 and the cleaning mechanism to achieve efficient cleaning of the gear ring before and after polishing. Specifically, the cleaning mechanism is fixedly connected to the drive shaft 400 of the polishing machine through the fixing mechanism 100, so that the drive shaft 400 of the polishing machine can drive the cleaning mechanism to rotate. In addition, the central axis of the fixing mechanism 100 is coaxial with the drive shaft 400 to ensure balance during rotation. The cleaning mechanism consists of a first mounting rod 210 and a second mounting rod 220, forming a spatial three-dimensional frame structure. The first mounting rod 210 is evenly distributed around the drive shaft 400, so that the cleaning unit 300 can cover different areas of the outer circumference of the gear ring during rotation. The second mounting rod 220 is arranged parallel to the drive shaft 400, so that the cleaning unit 300 can extend to the end face and side area of ​​the gear ring, thereby achieving all-round cleaning of the gear ring surface.

[0031] The auxiliary fixture for cleaning the gear ring of a double-sided polishing machine provided by this utility model uses a rotary drive to drive the cleaning unit 300 to clean the gear ring from all directions, avoiding the dead corner problem caused by traditional manual wiping or fixed-point spraying, and significantly improving cleaning efficiency and cleanliness. At the same time, the auxiliary fixture is equipped with a first mounting rod 210 and a second mounting rod 220 extending in different directions, which has high space utilization and reasonable overall structural design. It is suitable for various models of double-sided polishing machines, and the length of the mounting rods and the number of cleaning units 300 can be flexibly adjusted according to the size of the gear ring, which has strong versatility. Moreover, the automated cleaning process reduces the frequency of manual operation and reduces labor intensity.

[0032] In one embodiment of the present invention, the auxiliary tooling further includes a length adjustment component, and the first mounting rod 210 is connected to the fixing mechanism 100 through the length adjustment component.

[0033] The length adjustment unit can adjust the relative extension length between the first mounting rod 210 and the fixing mechanism 100, thereby enabling the cleaning unit 300 to accurately correspond to the toothed ring surface of different diameters. This eliminates the need to configure special tooling for each size, thus meeting the cleaning needs of polishing machines of different sizes and significantly improving the versatility of auxiliary tooling.

[0034] In one embodiment of the present invention, the length adjustment assembly includes a first slot 211 disposed along the axial direction of the first mounting rod 210 and a first fixing hole 130 disposed on the fixing mechanism 100. Bolts pass through the first slot 211 and the first fixing hole 130 in sequence to fix the first mounting rod 210 to the fixing mechanism 100.

[0035] like Figure 2 , Figure 3As shown, the first slot 211 extends axially along the first mounting rod 210, forming an elongated channel that allows the bolt to slide inside. The fixing mechanism 100 has multiple or one first fixing hole 130 corresponding to different positions. By inserting the bolt into the first slot 211 and screwing it into the first fixing hole 130, the first mounting rod 210 can be fixed at different extension lengths.

[0036] Through the interlocking of the bolt, the first slot 211, and the first fixing hole 130, the user can slide the first mounting rod 210 along the slot direction to a suitable length according to the diameter of the gear ring to be cleaned. Then, the bolt is inserted into the corresponding fixing hole and tightened, thus completing quick positioning and locking. The bolted connection has high structural strength and shear resistance, ensuring a stable and reliable connection between the first mounting rod 210 and the fixing mechanism 100 during high-speed rotation of the drive shaft 400, preventing loosening or detachment due to vibration or centrifugal force. Furthermore, the use of the first slot 211, the first fixing hole 130, and the bolt connection simplifies the structure and facilitates assembly and maintenance.

[0037] In summary, the length adjustment component described in this embodiment of the present invention, through the structure of the first slot 211 engaging with the first fixing hole 130 and being fixed by bolts, provides a length adjustment solution that is simple in structure, flexible in adjustment, and reliable in connection. It not only effectively improves the adaptability of auxiliary tooling to gear rings of different specifications, but also takes into account manufacturing costs, ease of use, and operational stability.

[0038] In one embodiment of the present invention, the auxiliary tooling further includes a height adjustment component, wherein the first mounting rod 210 and the second mounting rod 220 are fixedly connected by the height adjustment component.

[0039] By incorporating a height adjustment component, the vertical adjustability of the cleaning unit 300 is further enhanced, allowing the entire auxiliary fixture to more flexibly adapt to gear ring products with different structures, sizes, and installation positions. The height adjustment function enables the cleaning unit 300 to be precisely positioned based on the height differences of the gear ring's end face, achieving flexible vertical adjustment of the cleaning unit 300. This effectively covers all cleaning areas of the gear ring, significantly improving cleaning coverage and cleanliness, while also enhancing the equipment's versatility.

[0040] In one embodiment of the present invention, the height adjustment assembly includes a second mounting hole 221 disposed along the axial direction of the second mounting rod 220 and a first mounting hole 212 disposed on the first mounting rod 210. Bolts pass through the first mounting hole 212 and the second mounting hole 221 in sequence to fix the first mounting rod 210 and the second mounting rod 220.

[0041] like Figure 3 As shown, the second mounting hole 221 is a plurality of through holes evenly distributed along the axis of the second mounting rod 220, while the first mounting rod 210 is provided with a corresponding first mounting hole 212. The second mounting rod 220 is installed at the end of the first mounting rod 210 away from the fixing mechanism 100. By inserting bolts and locking them in different hole positions, multi-level adjustment of the height of the second mounting rod 220 relative to the first mounting rod 210 can be achieved.

[0042] Specifically, in actual use, users can select appropriate mounting hole positions according to the height of the toothed ring end face to be cleaned, adjust the second mounting rod 220 to the corresponding height, and then pass bolts through the first mounting hole 212 and the second mounting hole 221 and tighten them to complete quick fixing. This improves operational convenience.

[0043] The height adjustment component described in this embodiment of the present invention, by providing second mounting holes 221 distributed axially on the second mounting rod 220 and fixing it to the first mounting rod 210 with bolts, not only effectively enhances the adaptability of the auxiliary tooling to various gear ring products, but also takes into account manufacturing cost, usage efficiency and operational stability.

[0044] In one embodiment of the present invention, the connecting unit 200 further includes a crossbar 230 arranged perpendicularly to the second mounting rod 220. The crossbar 230 is installed at the end of the second mounting rod 220 away from the first mounting rod 210. The crossbar 230 and the second mounting rod 220 form a T-shaped structure. The cleaning unit 300 is fixedly connected to the crossbar 230.

[0045] This design further expands the spatial layout of the cleaning unit 300, enabling it to more effectively cover different areas of the toothed ring surface and improve the comprehensiveness and efficiency of the cleaning operation. Specifically, the T-shaped structure consists of a second mounting rod 220 and a crossbar 230 fixed perpendicularly to it. The second mounting rod 220 extends along the axis of the drive shaft 400 as the main support arm, while the crossbar 230 extends laterally as a mounting platform for the cleaning unit 300. A stable connection can be achieved between the two through welding, bolting, or integral molding, ensuring that the overall structure has good rigidity and torsional resistance. The cleaning unit 300 (such as a brush assembly, nozzle assembly, or scraper assembly) is fixed to the crossbar 230 using brackets, clips, or screws.

[0046] The T-shaped connection structure described in this embodiment of the invention expands the cleaning work space and enhances the cleaning function by adding a crossbar 230 to the end of the second mounting rod 220 and fixing it to the cleaning unit 300. This design not only improves the cleaning coverage and operational stability but also enhances the adaptability of the auxiliary tooling to various toothed ring structures.

[0047] In one embodiment of this utility model, the auxiliary tooling further includes a radial adjustment component, and the crossbar 230 and the cleaning unit 300 are fixedly connected through the radial adjustment component.

[0048] By setting a radial adjustment component, the cleaning unit 300 can be precisely adjusted to the optimal contact distance according to the diameter of the toothed ring, which further enhances the adjustability of the cleaning unit 300 in the horizontal direction. This allows it to more accurately fit the surface of toothed rings of different diameters, improving cleaning efficiency and coverage. It also enhances the adaptability and effectiveness of auxiliary tooling cleaning operations, providing a good surface condition foundation for subsequent automated polishing, inspection and other processes.

[0049] In one embodiment of the present invention, the radial adjustment assembly includes a second slot 231 disposed along the axial direction of the crossbar 230 and a positioning hole disposed on the cleaning unit 300. Bolts pass through the second slot 231 and the positioning hole in sequence to fix the crossbar 230 and the cleaning unit 300.

[0050] like Figure 3 As shown, the second slot 231 is an elongated through hole extending along the axis of the crossbar 230, allowing the cleaning unit 300 to slide radially within a certain range. The cleaning unit 300 is provided with a positioning hole for engaging with the second slot 231 and the bolt, thereby locking the cleaning unit 300 in the desired position. Specifically, the user can slide the cleaning unit 300 along the second slot 231 to a suitable position according to the outer diameter of the gear ring to be cleaned, and then insert the bolts into the second slot 231 and the positioning hole in sequence and tighten them to complete the quick installation and fixation of the cleaning unit 300.

[0051] The radial adjustment assembly adopts a combination of the second slot 231, positioning hole and bolt, providing a horizontal adjustment solution for the cleaning unit 300 that is simple in structure, flexible in adjustment, low in manufacturing difficulty and cost, highly versatile, easy to mass-produce and replace and maintain, and easy to disassemble and replace. It not only effectively enhances the adaptability of auxiliary tooling to gear ring products of different diameters, but also takes into account manufacturing cost, usage efficiency and operational stability.

[0052] In one embodiment of the present invention, the fixing mechanism 100 includes a mounting plate 110 and a snap-fit ​​member 120 evenly arranged circumferentially along the mounting plate 110. The snap-fit ​​member 120 is snapped and fixed with a slot on the outer peripheral surface of the drive shaft 400.

[0053] like Figure 2As shown, the mounting plate 110 has a circular structure and serves as the basic support structure for the entire auxiliary tooling. Multiple snap-fit ​​pieces 120 are evenly distributed circumferentially along its edge. These snap-fit ​​pieces 120 can extend into pre-set slots on the outer surface of the drive shaft 400 to achieve circumferential positioning and torque transmission. Specifically, the user can first place the mounting plate 110 onto the drive shaft 400, and then adjust the snap-fit ​​pieces 120 to align with the slots on the drive shaft 400 before gently pressing or rotating to complete the snap-fit. The snap-fit ​​pieces 120 and the slots employ a beveled guide or serrated engagement structure to enhance torsional resistance and anti-loosening performance, ensuring a stable connection even under high-speed rotation and preventing detachment due to centrifugal force or vibration.

[0054] The snap-fit ​​structure possesses excellent anti-loosening and self-locking capabilities, making it less prone to displacement or detachment during high-speed rotation. This reduces operational risks and enhances the safety and lifespan of the entire auxiliary tooling. Furthermore, the snap-fit ​​fixing mechanism 100 allows for quick installation and disassembly without complex tools, significantly improving equipment debugging efficiency and maintenance convenience. In addition, the multiple circumferentially distributed snap-fit ​​components 120 effectively distribute rotational torque, preventing structural fatigue caused by single-point stress and ensuring stable and reliable synchronous rotation between the auxiliary tooling and the drive shaft 400, guaranteeing the continuity and consistency of cleaning operations.

[0055] It should be noted that the present invention does not limit the type of the snap-fit ​​component 120. In one embodiment, the snap-fit ​​component 120 is an elastic hook, a sliding block, or an adjustable claw, etc.

[0056] In one embodiment of this utility model, the cleaning unit 300 is a brush, which is made of fine nylon filaments with a diameter of 0.1-0.3mm.

[0057] By using high-toughness, wear-resistant fine nylon bristles as the main body of the brush, with a diameter controlled between 0.1-0.3mm, the fine nylon bristles have good elasticity and cleaning ability, ensuring sufficient flexibility and contact area while avoiding scratches on the tooth ring surface caused by excessively coarse bristles. At the same time, they can penetrate deep into the tooth ring grooves and edge areas to effectively remove surface residues, significantly improving cleaning efficiency and cleanliness.

[0058] The brush is connected to the fixing mechanism 100 via a horizontal adjustment component, a radial adjustment component, and a height adjustment component. It can be precisely aligned according to the outer diameter and end face position of the toothed ring. Driven by the drive shaft 400, the auxiliary fixture rotates synchronously with the drive shaft 400, and the brush moves in a circular motion around the toothed ring. It utilizes rotational friction to remove dust, metal debris, and other minute impurities adhering to its surface, thus improving cleaning efficiency. In a preferred embodiment, multiple brush modules are provided, each responsible for cleaning the outer circular surface, end face, and tooth groove area.

[0059] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
