Description

Technical Field

[0001] This utility model relates to the field of glass tube processing technology, and in particular to a vertical quartz glass tube polishing device. Background Technology

[0002] Quartz glass tube polishing machines are specialized equipment used for precision polishing of the surface of quartz glass tubes. They aim to improve the surface smoothness, gloss, and flatness of the tubes to meet the high precision requirements of fields such as optics, semiconductors, and fiber optic communications.

[0003] A vertical glass tube polishing device disclosed in Chinese Patent Publication No. CN223251341U uses a spray mechanism to wash away the debris generated during polishing, ensuring the cleanliness of the glass tube after polishing and eliminating the need for separate cleaning of the glass tube. However, according to the vertical glass tube polishing device provided by related technologies and existing technologies, traditional glass tube polishing equipment requires polishing each glass tube individually, resulting in a long processing cycle, reduced overall processing speed, and differences in the force and grinding angle of different workpieces, directly causing fluctuations in the quality of batch products and making it difficult to guarantee consistency. In addition, traditional polishing often uses fixed-direction grinding, which can easily lead to uneven textures on the glass tube due to unidirectional grinding. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a vertical quartz glass tube polishing device.

[0005] The purpose of this utility model is achieved through the following technical solution: a vertical quartz glass tube polishing device, including a frame, a polishing component for rotating and polishing the glass tube is installed on the top of the frame, a revolution component for controlling the glass tube to rotate around the polishing component is provided below the polishing component on the frame, a plurality of rotation components are evenly provided on the top of the revolution component for forcing the glass tube to rotate when it revolves around the revolution component, each rotation component is provided with a three-jaw chuck for fixing the glass tube, and the plurality of rotation components are distributed in a circular array.

[0006] Preferably, the revolution assembly includes a rotating seat fixed to the bottom of the frame, a rotation drive is fixedly installed inside the rotating seat, a revolution shaft is fixedly provided at the output end of the rotation drive, the top of the revolution shaft passes through the rotating seat upward and a turntable is fixedly installed thereon, and the turntable is rotatably connected to the rotating seat.

[0007] Preferably, the rotation component includes a rotating platform rotatably mounted on the turntable, a rotation shaft is fixedly provided at the bottom of the rotating platform, and the bottom of the rotation shaft passes downward through the turntable and is fixedly provided with a gear.

[0009] Preferably, the rotating seat is fixedly provided with a toothed ring corresponding to the position of the gear.

[0010] Preferably, the three-jaw chuck is fixed to the top of the rotary table and the two are concentrically arranged.

[0011] Preferably, the bottom of the grinding disc is chamfered.

[0012] Beneficial effects:

[0013] This vertical quartz glass tube polishing equipment, by incorporating a revolution component and a rotation component, utilizes a multi-station parallel rotation processing design to simultaneously polish multiple glass tubes, significantly improving the overall processing speed. Simultaneously, the force and grinding angle of different workpieces are identical, avoiding batch product quality fluctuations and ensuring consistent polishing quality. Furthermore, the revolution trajectory combined with the rotational motion causes the glass tube to periodically change its relative position to the polishing disc, forming a spatial spiral grinding trajectory through motion superposition. This avoids the uneven texture caused by grinding in a single direction. During revolution, the radial clamping effect of the glass tube on the polishing disc not only enhances grinding stability but also counteracts radial vibration through multi-directional uniform pressure, preventing scratches and edge chipping caused by stress concentration. It also adapts to the deformation of the polishing disc to maintain consistent contact pressure, improving the uniformity of polishing thickness in batches. Attached Figure Description

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 7As shown, a vertical quartz glass tube polishing device includes a frame 1. A polishing assembly 2 for rotating and polishing the glass tube is mounted on the top of the frame 1. Below the polishing assembly 2, a revolution assembly 3 for controlling the rotation of the glass tube around the polishing assembly 2 is located on the frame 1. Multiple rotation assemblies 4 are evenly distributed on the top of the revolution assembly 3 to force the glass tube to rotate during its revolution. Each rotation assembly 4 is equipped with a three-jaw chuck 6 for fixing the glass tube. The multiple rotation assemblies 4 are arranged in a circular array. The quartz glass tube to be polished is fixed to the rotation assembly 4 using the three-jaw chuck 6. Then, the polishing assembly 2 is activated and slowly moves downwards to polish the side of the glass tube. During the process, the revolution component 3 controls the glass tube to revolve around the grinding component 2. At the same time, the rotation component 4 forces the three-jaw chuck 6 to rotate the glass tube, ensuring that each area of ​​the glass tube is uniformly ground and guaranteeing the uniformity of polishing. Multiple rotation components 4 are provided, which can polish multiple glass tubes at the same time, significantly improving the processing speed. At the same time, the force and grinding angle of different workpieces are the same, avoiding the quality fluctuation of batch products and ensuring the consistency of their polishing quality. In addition, the spatial spiral grinding trajectory is formed by the superposition of motion (revolution + rotation), avoiding the problem of uneven texture caused by grinding in one direction and ensuring the consistency of polishing quality of batch products.

[0026] like Figure 4 and Figure 5 As shown, the polishing assembly 2 includes an electric push rod 21 fixed to the top of the frame 1. The output end of the electric push rod 21 passes downward through the frame 1 and is fixedly mounted on a mounting plate 22. The mounting plate 22 and the frame 1 are vertically slidably connected by multiple limiting rods 25. A polishing machine 23 is fixedly mounted on the bottom of the mounting plate 22. A polishing disc 24 is fixedly mounted on the output end of the polishing machine 23. The bottom of the polishing disc 24 is chamfered. The electric push rod 21 drives the mounting plate 22 to move slowly downward along the limiting rods 25, so that the side of the polishing disc 24 contacts the surface of the vertically placed glass tube. During this process, the chamfer at the bottom of the polishing disc 24 can ensure that the side of the polishing disc 24 can smoothly overlap and contact the glass tube. At the same time, the polishing machine 23 drives the polishing disc 24 to rotate at high speed to polish the outer surface of the glass tube.

[0027] like Figure 4 As shown, the revolution assembly 3 includes a rotating seat 31 fixed to the bottom of the frame 1. A rotation drive 33 is fixedly installed inside the rotating seat 31. A revolution shaft 34 is fixedly provided at the output end of the rotation drive 33. The top of the revolution shaft 34 passes through the rotating seat 31 and a turntable 32 is fixedly installed thereon. The turntable 32 is rotatably connected to the rotating seat 31. The rotation drive 33 (such as a motor) drives the turntable 32 to rotate around the center of the rotating seat 31 through the revolution shaft 34, so that the rotating components 4 and the glass tube distributed in a circular array on the turntable 32 revolve synchronously around the polishing disc 24.

[0028] like Figures 2 to 7As shown, the rotating assembly 4 includes a rotating platform 41 rotatably mounted on a turntable 32. A rotating shaft 42 is fixedly mounted on the bottom of the rotating platform 41. The bottom of the rotating shaft 42 extends downward through the turntable 32 and is fixedly mounted with a gear 43. A gear ring 5 is fixedly mounted on a rotating seat 31 corresponding to the position of the gear 43. A three-jaw chuck 6 is fixed to the top of the rotating platform 41, and the two are concentrically arranged. The rotating platform 41 is connected to the gear 43 via the rotating shaft 42. When the turntable 32 revolves, the gear 43 meshes with the gear ring 5 fixed to the rotating seat 31, forcing the gear 43 to drive the rotating shaft 42 and the rotating platform 41 to rotate. The glass tube fixed by the three-jaw chuck 6 rotates synchronously with the rotating platform 41, ensuring that the glass tube rotates around its own axis during its revolution, guaranteeing that each area in contact with the polishing disc 24 is uniformly ground, thus ensuring the uniformity of polishing. Multiple rotating platforms 41 are provided, enabling simultaneous polishing of multiple glass tubes. This process significantly improves processing speed. During processing, different workpieces experience the same force and grinding angle, avoiding quality fluctuations in batch products and ensuring consistent polishing quality. Simultaneously, the surrounding glass tubes create a radial clamping effect on the grinding disc 24, enhancing grinding stability and offsetting radial vibrations during grinding through multi-directional uniform pressure. This prevents scratches or chipping on the glass tube surface caused by localized stress concentration. Furthermore, it adapts to the slight deformation of the grinding disc, ensuring consistent contact pressure between all glass tubes and the disc, further improving the uniformity of polishing thickness in batch products. In addition, the revolution trajectory combined with rotational motion causes the glass tubes to periodically change their relative position to the grinding disc 24. Through the superposition of motions (revolution + rotation), a spatial spiral grinding trajectory is formed, avoiding uneven texture caused by grinding in a single direction and ensuring consistent polishing quality in batch products.

[0029] The work process is as follows:

[0030] S1: As Figure 3 As shown, the quartz glass tube to be polished is fixed on the rotating table 41 by the three-jaw chuck 6, ensuring that the axis of the glass tube is precisely aligned with the center of the rotating table 41, and multiple glass tubes are evenly distributed along the circumference of the turntable 32.

[0031] S2: As Figure 3 As shown, the electric push rod 21 then extends, pushing the mounting plate 22 and the polishing disc 24 to slowly descend, so that the side of the polishing disc 24 makes smooth contact with the surface of the glass tube.

[0032] S3: As Figure 3 and Figure 4 As shown, at this time, the polishing machine 23 starts, driving the polishing disc 24 to rotate at high speed to grind and polish the surface of the glass tube. At the same time, the rotating drive component 33 drives the turntable 32 to rotate at a constant speed through the revolution axis 34, so that the self-rotating table 41 on the turntable 32 drives the glass tube to revolve around the revolution axis 34.

[0033] S4: As Figure 4 and Figure 7 As shown, the rotating table 41 is connected to the gear 43 through the rotating shaft 42. When the turntable 32 revolves, the gear 43 meshes with the gear ring 5 fixed to the rotating seat 31, forcing the gear 43 to drive the rotating shaft 42 and the rotating table 41 to rotate synchronously. The glass tube fixed by the three-jaw chuck 6 then realizes the compound motion of revolution and rotation, ensuring that every area of ​​the glass tube surface in contact with the polishing disc 24 is uniformly ground, effectively ensuring polishing accuracy and surface consistency.

[0034] S5: As Figure 3 As shown, the device, through the design of the multi-station rotary table 41, can polish multiple glass tubes simultaneously, significantly improving the overall processing speed. At the same time, the force and grinding angle of different workpieces are the same, avoiding the quality fluctuation of batch products and ensuring the consistency of their polishing quality.

[0035] S6: As Figure 3 As shown, in addition, the revolution trajectory combined with the rotation motion causes the glass tube to periodically change its relative position with the polishing disc 24. Through the superposition of motion (revolution + rotation), a spatial spiral grinding trajectory is formed, which avoids the problem of uneven texture caused by grinding in one direction and ensures the consistency of polishing quality of batch products.

[0036] S7: As Figure 3 As shown, during the processing, the glass tubes on all sides can also form a radial clamping effect on the grinding disc 24. In addition to enhancing grinding stability, they can also counteract radial vibration during the grinding process through multi-directional uniform pressure, avoiding scratches or chipping of the glass tube surface caused by local stress concentration. At the same time, this dynamic clamping can adapt to the slight deformation of the grinding disc, ensuring that the contact pressure between all glass tubes and the grinding disc is consistent, further improving the uniformity of the polishing thickness of batch products.

[0037] The grinding machine 23, electric push rod 21, three-jaw chuck 6 and rotary drive 33 are known technologies in this application, and therefore their specific structures and working principles are not described in detail.
