Description

Technical Field

[0001] This invention belongs to the field of quartz tube processing technology, specifically a quartz tube fire repair process and apparatus. Background Technology

[0002] Quartz tubes often develop defects such as bubbles, cracks, ruptures, or scratches during production, transportation, or use. The commonly used repair method is quartz fire repair: the area to be repaired is cut using an oxyhydrogen welding torch and filled with quartz welding rods. After fire repair, nodules, protrusions, or weld residues often form on the outer wall of the quartz tube. These residues cause the outer and inner diameters to deviate from the design dimensions and result in surface roughness, affecting the sealing, thermal and optical properties of the quartz tube, and even affecting assembly and device operation.

[0003] Traditional manual or semi-automatic grinding after restoration has several problems:

[0004] 1. Most existing equipment relies on manual vision or simple mechanical positioning for centering, resulting in high eccentricity. The grinding results do not meet the requirements for roundness and wall thickness uniformity, and the tube body is easily damaged.

[0005] 2. Low processing efficiency and poor processing consistency make it difficult to meet the requirements of batch production and precision.

[0006] 3. Traditional clamps are not versatile enough for quartz tubes of various diameters / lengths, especially for thin-walled long tubes and fragile quartz tubes, which pose processing risks. Light clamping may cause slippage or deviation under grinding force.

[0007] 4. Using rigid fixtures or strong clamping forces can cause crack propagation or damage in thin-walled or defective areas. After heat repair, there is local thermal stress and structural discontinuity in the area. Traditional processes are prone to causing secondary damage or over-processing, leading to scrap.

[0008] Therefore, there is an urgent need for a device that can automatically and precisely center and stably clamp quartz tubes, grind the inner diameter or outer circle of the quartz tube while rotating, and is adaptable to quartz tubes of different diameters and lengths, in order to improve repair quality and production efficiency, and reduce defect rate and human risk. Summary of the Invention

[0009] The purpose of this invention is to provide a quartz tube fire repair process and apparatus to solve the problems mentioned in the background art. The objectives of this invention are: to improve centering accuracy and roundness; to achieve automatic centering and closed-loop control between the tube axis and the workpiece rotation axis without damaging the quartz tube; to effectively reduce eccentricity; to improve the roundness and coaxiality of the outer and inner diameters; to ensure uniform wall thickness; to reduce processing risks; and to reduce the risk of secondary damage or breakage to the quartz tube through flexible clamping and online torque / vibration monitoring, thereby improving processing consistency and efficiency. The automated process enables batch and highly consistent repairs, shortening single-piece processing time and reducing manual labor dependence. Modular fixtures and replaceable grinding wheels allow the equipment to adapt to quartz tubes of different diameters and lengths, reducing fixture costs. With time-to-time tracking and quality control, processing parameters and measurement results are recorded in real time, facilitating quality traceability and process improvement. Non-contact sensors monitor the eccentricity of the quartz tube in real time, and the controller drives the clamping or fine-tuning mechanism for active centering correction. Combined with the axial positioning mechanism and end clamping mechanism, the stability of the quartz tube's position and rotational coaxiality during the repair process are ensured, improving repair accuracy. Low-pressure cooling spray is used to purge the nozzle, and an inert evaporable medium is used for cooling and debris removal. This not only prevents the quartz tube from being damaged by high temperature or contact with poor medium, but also keeps the work area clean, improving the safety and effectiveness of the repair process.

[0077] In this embodiment: the end clamping arm 5 rotates on the clamping arm mounting base 22 and docks with one of the chucks 8 to complete the positioning of the quartz tube 9. The clamping surface of the end clamping arm 5 is made of elastic buffer material, such as ceramic / polymer coating or elastic film, or uses radially evenly distributed elastic claws to achieve flexible contact and avoid point contact stress concentration.

[0078] Specifically: The end drive component includes an end cylinder hinge seat 21 and an end clamping cylinder 4.

[0079] In this embodiment, the model of the end clamping cylinder 4 can be selected from those available on the market as needed, which will not be elaborated here. The end clamping arm 5 is rotated on the clamping arm mounting seat 22 by controlling the extension and retraction of the end clamping cylinder 4 to complete the use. The end cylinder hinge seat 21 does not affect the extension and retraction control of the end clamping cylinder 4.

[0080] Specifically: Each axial positioning mechanism includes an axial drive component, an axial connecting component, and an axial positioning arm 11. The axial drive component is located on one side of the outer surface of the operating table 19, the axial connecting component is located on the top of the operating table 19, one end of the axial positioning arm 11 is located on the axial drive component, and the other end of the axial positioning arm 11 is located on the axial connecting component.

[0081] In this embodiment, the axial positioning arm 11 is used to press and position the quartz tube 9 axially.

[0082] Specifically: The axial drive component includes an axial positioning cylinder 6 and an axial cylinder hinge seat 24. The axial cylinder hinge seat 24 is fixedly connected to the bottom of one side of the outer surface of the operating table 19. The axial positioning cylinder 6 is rotatably connected to the axial cylinder hinge seat 24, and the output end of the axial positioning cylinder 6 is rotatably connected to the axial positioning arm 11.

[0083] In this embodiment, the model of the axial positioning cylinder 6 can be selected from those available on the market as needed, which will not be elaborated on here. The angle of the axial positioning arm 11 is controlled by the extension and retraction of the axial positioning cylinder 6, and the axial cylinder hinge seat 24 does not affect the extension and retraction control of the axial positioning cylinder 6.

[0084] Specifically: The axial connection component includes a connecting rod mounting base 23 and an axial connecting rod 7.

[0086] Specifically: The top of the operating table 19 is equipped with multiple support seats 17, and the top of each support seat 17 is rotatably connected to two support rollers 18.

[0087] In this embodiment, the support seat 17 and the two support rollers 18 are used together to support the bottom of the quartz tube 9 and complete the use. For long quartz tubes 9, the support seat 17 and the two support rollers 18 can prevent bending and vibration. The support position is adjusted according to the length of the workpiece.

[0088] Specifically: a storage tray 16 is installed at the center of one end of the top of the control panel 19, and a control module 3 is installed on one side of the outer surface of the control panel 19.

[0090] In use, the system is started via control module 3 to perform a self-test, confirming that the device is working properly. The quartz tube 9 is placed horizontally between the chucks 8 of the two support frames 15, with its bottom supported by support rollers 18 on multiple support seats 17 for easy rolling adjustment. Control module 3 operates the end clamping cylinder 4 to push the end clamping arm 5 to rotate around the clamping arm mounting seat 22, reliably engaging it with the corresponding chuck 8, initially clamping the quartz tube 9 from one end. Control module 3 then activates the two axial positioning cylinders 6, which, through the linkage of the axial positioning arm 11 and the axial connecting rod 7, gently press the positioning end of the axial positioning arm 11 against the appropriate position of the quartz tube 9 to prevent axial movement. The quartz tube 9 is then rotated by the rotating motor 12, allowing the part to be polished to be placed... The area is adjusted to a position that is easy to operate. The robotic arm 20 is controlled to precisely move the grinding wheel 10 to the area that needs to be ground. The grinding wheel 10 is started, and at the same time, the rotating motor 12 is started to make the quartz tube 9 rotate at a uniform speed. The robotic arm 20 controls the grinding wheel 10 to grind with appropriate pressure and path. During the grinding process, the low-pressure cooling spray nozzle 13 continues to work to cool and remove debris. After the grinding is completed, the grinding wheel 10 is turned off. The robotic arm 20 is controlled to move the grinding wheel 10 to a safe position. The rotating motor 12 is stopped.
