[0002] The integrated quartz tube processing machine based on flexible traction is consistent with the essential attribute of the industrial mother machine for providing core equipment for manufacturing and determining the processing capacity and precision benchmark of the industrial chain. The machine provides an integrated processing solution for the key basic material quartz tube, can break through the pain points such as brittleness and easy cracking, high-precision forming difficulty, and meets the customized needs of strategic emerging industries such as semiconductors and photovoltaics for quartz tube processing. The processing precision and stability directly determine the manufacturing level of downstream core components. At the same time, it supports the basic manufacturing link of multiple strategic industrial chains, and establishes the quartz tube processing precision benchmark and standardized process through the integration of core technologies, defines the processing threshold of the subdivided field, and undertakes the key functions of the industrial mother machine for providing processing capacity for the downstream and driving the development of the industrial chain.

[0003] In the Chinese patent with the publication number CN118559524B, the application discloses an ultra-fine automatic feeding and discharging centerless grinding machine, which comprises a support table, a conveyor, a guide wheel assembly, a grinding wheel assembly, a lifting assembly, a driving mechanism, a limiting grinding mechanism, a proximity sensor and a controller.

The limiting grinding mechanism is arranged on the opposite side of the conveyor. Thus, while reducing the cost of the equipment, the quartz tube can be limited during the machining process to ensure the stability of the quartz tube during machining, reduce the probability of defective products, and improve the accuracy during polishing. The inner wall and the outer wall of the quartz tube can be polished at the same time, saving time and effort.

[0004] For the above and existing related technologies, the inventors believe that the following defects often exist: when the quartz tube processing machine polishes the quartz tube, it mainly relies on the guide wheel to support and feed the quartz tube.

There are abnormal protrusions on part of the surface of the quartz tube. During rotation, the protruding part rotates to the contact line position, which causes instantaneous contact pressure to change suddenly, resulting in irregular movement of the quartz tube in the up-down direction perpendicular to the line contact, affecting the polishing quality and efficiency of the quartz tube.

[0020] It is easily understood that, according to the technical solution of the present application, one of ordinary skill in the art can propose a variety of structural ways and implementation ways that can be replaced with each other without changing the spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary descriptions of the technical solution of the present application, and should not be considered as the whole or as a limitation or restriction on the technical solution of the present application.

[0021] In the processing scene of polishing quartz tube in a centerless grinding machine, the core transmission and positioning rely on the linear contact between the guide wheel and the quartz tube. The guide wheel drives the quartz tube to rotate and feeds axially through friction, while limiting its radial displacement. The side of the quartz tube away from the guide wheel is in contact with the grinding wheel for polishing, and the quartz tube and the grinding wheel are also in linear contact. Since the linear contact itself has a small contact area and low radial constraint strength, when there is an abnormal protrusion on the surface of the quartz tube, such as a local bump left by forming, a height difference after edge collapse repair, or uneven surface roughness, such as axial stripes or local wall thickness deviation, the instantaneous contact pressure between the protrusion and the guide wheel will suddenly change during the rotation of the quartz tube, breaking the stable friction force balance between the guide wheel and the quartz tube, causing the quartz tube to move irregularly in the up-down direction perpendicular to the linear contact. This movement will continuously shift the relative grinding position between the quartz tube and the grinding wheel, causing uneven grinding depth, ultimately leading to a decrease in the outer diameter size accuracy of the quartz tube. In severe cases, the movement may cause the quartz tube to collide with the equipment components, causing the workpiece to crack or the equipment to be damaged, directly affecting the processing quality and production efficiency. In order to solve the above problems, the following improvements are made.

[0022] Referring to Figure 1 With Figure 2 As shown in the figure, the present application provides a technical solution: an integrated quartz tube processing machine based on flexible traction, comprising: a machine tool body 1, a guide wheel 2 and a grinding wheel 7 are installed side by side on the top of the machine tool body 1, an arc-shaped opening is formed on the side of the guide wheel 2 close to the grinding wheel 7, a flexible traction assembly 3 is installed inside the arc-shaped opening, the flexible traction assembly 3 includes a flexible conveyor belt 301, a belt drive mechanism 304 is installed on the back of the guide wheel 2, a drive roller 302 is fixedly connected to the output end of the belt drive mechanism 304, the drive roller 302 is inserted into the inside of the flexible conveyor belt 301, the drive roller 302 is used to drive the flexible conveyor belt 301, and the drive roller 302 is symmetrically provided with two groups about the horizontal central axis of the guide wheel 2, the belt drive mechanism 304 simultaneously drives the two groups of drive rollers 302 to rotate in the same direction, thereby rotating the flexible conveyor belt 301, the flexible conveyor belt 301 and the grinding wheel 7 are provided with a quartz tube workpiece 8, the rotation direction of the flexible conveyor belt 301 is consistent with the rotation direction of the grinding wheel 7, the flexible conveyor belt 301 keeps relative rotation with the grinding wheel 7 with the quartz tube workpiece 8, so that the grinding wheel 7 grinds the outer wall of the quartz tube workpiece 8, and the outer wall of the flexible conveyor belt 301 is provided with an inclined groove, which not only increases the friction between the flexible conveyor belt 301 and the quartz tube workpiece 8, but also synchronously pushes the quartz tube workpiece 8 forward during the rotation of the flexible conveyor belt 301 with the quartz tube workpiece 8.

[0023] Please refer to Figure 4 With Figure 5As shown, the inner part of the flexible conveying belt 301 is also provided with a tensioning roller 303, which is used to support the flexible conveying belt 301 from the inner side, and the end of the tensioning roller 303 is provided with a tensioning mechanism 305, which is fixedly connected to the inner wall of the guide wheel 2 away from one end of the tensioning roller 303. The tensioning roller 303 is used to support the flexible conveying belt 301, and the two groups of tensioning mechanisms 305 symmetrically arranged at the end of the tensioning roller 303 are used to keep the flexible conveying belt 301 at a proper tensioning degree.

[0024] As shown in the figure, Figure 3 As shown in the figure, Figure 4 As shown, the inner part of the guide wheel 2 is also provided with a limiting assembly 4, which is symmetrically arranged in two groups about the horizontal central axis of the quartz tube workpiece 8, and the two groups of limiting assemblies 4 are supported from the inner wall of the flexible conveying belt 301, so that the flexible conveying belt 301 is attached to the side of the quartz tube workpiece 8 away from the grinding wheel 7, and the flexible conveying belt 301 between the two groups of limiting assemblies 4 is in an arc shape and wrapped around the side of the quartz tube workpiece 8, which can effectively increase the contact support area between the flexible conveying belt 301 and the quartz tube workpiece 8. The two groups of limiting assemblies 4 limit the quartz tube workpiece 8 from moving upward or downward respectively; The two groups of limiting assemblies 4 provide stable support from the vertical direction of the workpiece side, tightly pressing the flexible conveying belt 301 against the workpiece surface, so that the flexible conveying belt 301 forms a surface contact with the workpiece in a semi-wrapped manner, which replaces the original line contact of the guide wheel and greatly expands the force support area of the quartz tube workpiece 8. This structure not only directly suppresses the tendency of the quartz tube workpiece 8 to move due to protrusions from the rigid constraint of the limiting assembly 4 in the upward and downward directions, but also takes advantage of the flexible fitting characteristics of the flexible conveying belt 301 to allow the abnormal protruding parts on the surface of the quartz tube workpiece 8 to be adaptively wrapped by the conveying belt, rather than producing instantaneous pressure sudden change when in line contact with the guide wheel, thereby avoiding the imbalance of friction force caused by protrusions and irregular movement. This significantly improves the radial stability of the workpiece during rotation, effectively controls the upward and downward movement amplitude, ensures uniform grinding depth, and further improves the outer diameter size precision and surface finish of the quartz tube. The semi-wrapped support of the flexible conveying belt 301 can reduce the hard impact on the workpiece surface, reduce the risk of cracking of the quartz tube caused by movement collision, and improve the processing compatibility and yield.

[0025] As shown in the figure, Figure 7 As shown in the figure, Figure 9As shown, the limiting assembly 4 includes two groups of support inner columns 401, one end of one group of support inner columns 401 is provided with a retreat sliding groove 405, and the other group of support inner columns 401 is fixedly connected with a retreat sliding block 404, the retreat sliding block 404 is slidingly connected in the inside of the retreat sliding groove 405, the outside of the support inner column 401 is sleeved with a rotating sleeve 403, and the rotating sleeve 403 is rotatably connected with the support inner column 401, one end of the support inner column 401 away from the retreat sliding groove 405 is fixedly connected with a mounting end 402, the mounting end 402 is inserted into the inside of the telescopic outer cylinder 502, and the mounting end 402 is fixedly connected with the telescopic outer cylinder 502. The limiting assembly 4 is designed in two sections, and the two sections are slidingly connected through the retreat sliding block 404 and the retreat sliding groove 405. When the surface of the quartz tube workpiece 8 is abnormally protruding and contacts a certain section of the limiting assembly 4, this section can retreat backward through the sliding structure to adapt to the protrusion, avoiding the overall deviation of the supporting roller caused by excessive local stress. The other section not affected by the protrusion always remains in place, continuously adhering to the surface of the quartz tube workpiece 8 and providing stable support to the flexible conveying belt 301, effectively preventing the loss of supporting force caused by single-section retreat, and avoiding the up-and-down movement or rotational imbalance of the quartz tube workpiece 8, ensuring that the quartz tube is always in a stable supporting state during polishing, reducing the grinding precision deviation caused by interrupted support, and improving the stability of the machining process and the yield of the final product.

[0026] Please refer to Figure 3 and Figure 6 As shown, the end of the limiting assembly 4 is provided with a retreat assembly 5, the retreat assembly 5 includes a telescopic inner column 501, a telescopic outer cylinder 502 and a proximity sensor 503, the telescopic outer cylinder 502 is sleeved on the end of the telescopic inner column 501, and the telescopic outer cylinder 502 is slidingly connected with the telescopic inner column 501, the inside of the telescopic outer cylinder 502 is provided with a cavity, and the inside of the cavity is provided with a first spring 504 and a second spring 505, the elastic coefficient of the second spring 505 is smaller than that of the first spring 504, the second spring 505 provides preliminary buffering retreat, and the first spring 504 provides strong support to prevent excessive retreat, the two are matched to adapt to different height protrusions, and avoid the jamming or instability problem of single elastic structure, ensuring the stability and precision of quartz tube polishing, one end of the second spring 505 is fixedly connected with the first spring 504, and the other end of the second spring 505 is fixedly connected with the telescopic outer cylinder 502, one end of the first spring 504 away from the second spring 505 is fixedly connected with the telescopic inner column 501, and the telescopic inner column 501 is fixedly connected to the inner wall of the guide wheel 2.

[0027] The limiting assembly 4 is provided with a retreat assembly 5 at both ends, so that the limiting assembly 4 can realize flexible adaptation and automatic reset. When the abnormal protrusion on the surface of the quartz tube workpiece 8 rotates to the position of the limiting assembly 4, the retreat assembly 5 can be shrunk under the pressure of the protrusion, so that the limiting assembly 4 can adaptively retreat backward, avoiding the rigid support and the direct collision of the protrusion, which can cause jamming or excessive local stress of the quartz tube, and at the same time, the elastic force can keep the limiting assembly 4 and the quartz tube workpiece 8 in continuous contact, preventing the support from being interrupted. After the protrusion part rotates away from the limiting assembly 4, the retreat assembly 5 provides a rebound force to drive the limiting assembly 4 to reset, ensuring that the subsequent limiting assembly 4 can still provide stable upward and downward constraints to the quartz tube workpiece 8.

[0028] The proximity sensor 503 includes a transmitting end and a receiving end. The transmitting end is fixedly connected to the top of the telescopic outer cylinder 502, and the receiving end is fixedly connected to the top of the telescopic inner column 501. When the proximity sensor 503 at the end of the two sets of limiting assemblies 4 detects that the transmitting end and the receiving end are close, a signal is transmitted to the flexible traction assembly 3 to control the flexible traction assembly 3 to pause work. When the abnormal protrusion on the surface of the quartz tube workpiece 8 rotates to the position of one of the limiting assemblies 4, the limiting assembly 4 at this position retreats. At this time, the flexible traction assembly 3 is still in a moving state and rotates with the quartz tube workpiece 8 and feeds it. When the abnormal protrusion part of the quartz tube workpiece 8 rotates to the contact position of the polishing wheel 7, the polishing wheel 7 cannot retreat because of the rigid contact between the protrusion part and the polishing wheel 7. At this time, the quartz tube workpiece 8 moves horizontally towards the flexible traction assembly 3 under the pressure of the protrusion part, pushing the upper and lower limiting assemblies 4 to retreat backward synchronously. At this time, the proximity sensor 503 transmits a signal to control the flexible traction assembly 3 to stop rotating, limiting and fixing the quartz tube workpiece 8, so that the abnormal protrusion part of the quartz tube workpiece 8 stays in the contact position of the polishing wheel 7 for targeted polishing. After the protrusion part is polished, the quartz tube workpiece 8 is reset, and the receiving end and the transmitting end of the proximity sensor 503 are moved away to a normal distance, which controls the flexible traction assembly 3 to run again, continuing to rotate and feed the quartz tube workpiece 8, so that it can receive the polishing of the polishing wheel 7.

[0029] When the abnormal protruding part of the quartz tube workpiece 8 is opposite the grinding wheel 7, the flexible traction assembly 3 stops to make the protruding part always in the grinding area, avoiding the misalignment of the protrusion and the grinding wheel 7 due to the continuous rotation or feeding of the quartz tube workpiece 8, realizing targeted grinding, which can not only ensure that the protruding part is fully ground, but also reduce the unnecessary grinding of the normal area around the protrusion, significantly improving the outer diameter size accuracy and surface flatness of the quartz tube workpiece 8; on the other hand, after grinding, the conveying belt resumes operation in time, allowing the quartz tube workpiece 8 to continue circumferential grinding and axial feeding, without the need for manual intervention to connect the subsequent processing process, ensuring processing continuity and improving production efficiency, while reducing the secondary processing or waste caused by inaccurate grinding of the protrusion, further reducing production cost and improving yield.

[0030] Please refer to Figure 1 and Figure 8 As shown in the drawings, the bottom of the quartz tube workpiece 8 is provided with a support assembly 6, the support assembly 6 includes a support rod 601, the support rod 601 is fixedly connected to the top of the machine tool main body 1, the top of the support rod 601 is fixedly connected with a support block 602, and the top of the support block 602 is provided with a plurality of silica gel balls 603 at equal intervals, and the silica gel balls 603 are rotatably connected with the support block 602; the support assembly 6 is used to provide support to the quartz tube workpiece 8 from the bottom, and the silica gel balls 603 rotatably arranged on the top of the support block 602 are used to reduce the friction between the silica gel balls 603 and the quartz tube workpiece 8, so as to ensure smooth feeding of the quartz tube workpiece 8.

[0031] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should be within the protection scope of the present application.
