Description

Technical Field

[0001] This invention relates to the field of grinding devices for the inner holes of quartz tubes, specifically to a grinding device and method for the inner holes of quartz tubes. Background Technology

[0002] CN202411327823.5 discloses a grinding device and method for the inner arc surface of quartz tubes. The device achieves the pressing and grinding of quartz tubes through the cooperation of a lower frame ring, a lifting platform, a triangular shell, a support shell, an upper clamping ring, a push wheel, a push frame, and a grinding rod.

[0003] However, many of the technical features used in the aforementioned applications for pressing and polishing quartz tubes make the entire process relatively complex and prone to malfunctions during adaptation. Furthermore, the horizontal placement of the quartz tube and the use of "protrusions" to limit its movement prevents the smooth discharge of polished debris, causing it to accumulate inside the tube for extended periods. This can easily scratch the inner wall of the quartz tube and affect the polishing quality. Therefore, this invention provides a device and method for polishing the inner hole of quartz tubes. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding device for the inner hole of quartz tubes to solve the problem of debris not being discharged as mentioned in the background art.

The multiple sets of insert rods are located between the multi-faceted ring and the inner edge ring, and their two ends are bolted to the multi-faceted ring and the inner edge ring, respectively. Each set of insert rods passes through a multi-faceted tube. Two pairs of lifting cylinders are bolted to the bottom of the multi-faceted pool and the lifting assembly, respectively, and their drive ends are bolted to the lower side of the inner edge ring and the multi-faceted ring, respectively.

[0012] Preferably, the clamps on any pair of opposite surfaces are different in size from the clamps on other opposite surfaces, so as to match quartz tubes of different specifications; a limiting cylinder is fixedly connected to each limiting hole on any pair of opposite surfaces; and multiple insertion holes communicating with the middle of the multifaceted tube body are also provided between any adjacent surfaces.

[0013] Preferably, each lifting assembly includes an L-shaped fixing plate and a lead screw assembly. The horizontal portion of the fixing plate is fixedly connected to the outer wall of any one side of the multi-faceted pool, and the vertical portion is fixedly connected to the lead screw assembly facing the side of the multi-faceted pool.

[0014] Preferably, the grinding assembly includes a lifting plate, a connecting plate, a grinding component, and a driving component. The connecting plate is bolted to the upper side of the lifting plate, and both ends of the lifting plate are bolted to a pair of lead screw assemblies. The driving component is located on the upper side of the connecting plate, and the upper end of the grinding component passes through the connecting plate and is connected to the driving component for transmission.

[0015] Preferably, the grinding component includes multiple sets of grinding rods disposed above the multi-faceted tube body, the grinding rods passing through and rotatably connected to the connecting plate; the upper end of the grinding rod is fixedly connected to a gear and meshes with each other, and the lower end is detachably connected to a grinding head; a drive component is connected between adjacent sets of grinding rods; each grinding rod is also provided with a liquid guiding hole.

[0016] A method for grinding the inner hole of a quartz tube is also provided, comprising the following steps:

[0017] S1. Workpiece loading and positioning: Place multiple quartz tubes to be ground in the working area of ​​a pair of clamping units set up above and below, adjust the axial position of the quartz tubes so that the central axis of each quartz tube coincides with the center line of the clamping mouth of the multi-faceted tubes that are one-to-one in the pair of clamping units, and complete the loading and positioning.

[0018] S2. Workpiece clamping and fixing: Activate the two pairs of lifting cylinders set between the multi-faceted tube seat and the lifting assembly, drive the pressing assembly to move down in the vertical direction, and drive the multiple multi-faceted tubes located above through the pressing assembly to move down synchronously. Apply radial clamping force to the quartz tube through the clamping mouth of the upper and lower sets of multi-faceted tube bodies, and close the lifting cylinder after the rigid fixing of the quartz tube is completed.

[0019] S3. Grinding path execution: Start the grinding assembly bolted to a pair of lifting components and control the grinding head of the grinding assembly to rotate; at the same time, the lifting components drive the grinding assembly to feed at a constant speed along the axial direction of the quartz tube, so that the grinding head of the grinding assembly enters the inner hole of the quartz tube and completes the grinding of the entire length of the inner hole surface according to the preset axial feed rate.

[0020] S4. Grinding and retraction reset: After the inner hole of the quartz tube is ground to the preset process requirements, the lifting component drives the grinding component to feed in the reverse direction, so that the grinding head is completely separated from the inner hole of the quartz tube, and then the lifting component and the grinding component are closed.

[0021] S5. Workpiece unloading and removal: Restart the two pairs of lifting cylinders to drive the pressing assembly to move upward, which in turn moves the multiple multi-faceted tubes located above upward synchronously, releasing the radial clamping force on the quartz tube. Finally, remove the polished quartz tube from the work area to complete the polishing of a single batch of quartz tubes.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Effective debris removal is achieved through a multi-faceted tube body positioned vertically and clamped. During polishing, coolant is injected through the guide holes in the polishing rod, carrying the polished debris sequentially through the inner wall of the quartz tube, the lower multi-faceted tube body, and the guide channels of the multi-faceted tube base, flowing into the multi-faceted pool, and finally being discharged from the outlet. This top-down flow design ensures that polishing debris falls downwards and is immediately carried away by the coolant, preventing it from accumulating inside the quartz tube and causing secondary scratches on the inner wall, thus guaranteeing polishing quality.

[0024] Easy to operate and highly compatible, each multi-faceted tube body has various sizes of clamps on different sides, allowing for easy switching between different diameter quartz tubes by simply flipping the multi-faceted tube body. Each multi-faceted tube body is individually designed; the corresponding multi-faceted tube body can be disassembled by removing the side rods and fixing caps, enabling simultaneous grinding of quartz tubes of different sizes, greatly improving adaptability to different workpiece sizes and changeover efficiency.

[0025] Easy to operate and highly stable: The clamping unit automatically releases and releases the clamp via a lifting cylinder, while the grinding assembly is precisely raised and lowered by a lead screw assembly. Furthermore, the inclusion of a limiting cylinder and limiting assembly enhances the stability of the quartz tube clamping and the radial stability of the grinding rod during rotation, respectively. This results in a high degree of automation, simple operation, and smooth, reliable performance throughout the grinding process. Attached Figure Description

Detailed Implementation

[0040] Example 1:

[0041] Please see Figures 1-13 As shown, the present invention provides a technical solution: Figures 1-2 As shown, a quartz tube inner hole grinding device includes a multi-faceted tube seat 1, a pair of clamping units 2, a pressing component 3, a pair of lifting components 4, a grinding component 5, and two pairs of lifting cylinders 7. The pair of lifting components 4 are respectively arranged on any two sides of the multi-faceted tube seat 1 and are arranged opposite to each other.

[0042] A pair of clamping units 2 are arranged vertically, with multiple quartz tubes 8 positioned between them. Each clamping unit 2 includes multiple faceted tubes 21, with the faceted tubes 21 in each pair of clamping units corresponding one-to-one for clamping the quartz tubes 8. The multiple faceted tubes 21 located below correspond one-to-one with the upper side of the faceted tube seat 1 located between adjacent components 4 and are bolted together. Two pairs of lifting cylinders 7 are respectively located at the bottom of the faceted tube seat 1 and the lifting component 4, with their driving ends connected to the pressing component 3. The pressing component 3 passes through the multiple faceted tubes 21 located above, and is driven to rise and fall by the lifting cylinders 7, thereby causing the multiple faceted tubes 21 located above to move up or down to loosen or clamp the quartz tubes 8. A grinding component 5 is located above the faceted tubes 21, with both ends bolted to a pair of lifting components 4. The grinding component 5 is driven into the quartz tube 8 by the descent of the lifting components 4 to grind the inner wall of the quartz tube 8.

[0043] like Figures 3-4 As shown, the multifaceted tube base 1 includes a multifaceted pool 11 and a multifaceted base 12. The multifaceted base 12 is fixedly connected to the multifaceted pool 11 and arranged coaxially. A multifaceted groove 111 is formed between the outer wall of the multifaceted base 12 and the inner wall of the multifaceted pool 11. A liquid outlet hole 112 is opened in the middle of the multifaceted pool 11. Any two opposite pairs of outer walls of the multifaceted pool 11 are fixedly connected to a pair of lifting components 4. The multifaceted base 12 is a hollow multifaceted tubular structure. Multiple upper surfaces of the multifaceted base 12 located between the pair of lifting components 4 are defined as connecting surfaces 121, each connecting surface 121 corresponding to a multifaceted tube 21. A pair of fixing caps 13 are bolted to each connecting surface 121 for bolting to both ends of the corresponding multifaceted tube 21 to fix the multifaceted tube 21. Multiple guide holes 122 are also opened between each pair of fixing caps 13. The guide holes 122 penetrate the multifaceted base 12 vertically and are used for the insertion of the corresponding multifaceted tube 21. Each guide hole 122 has a guide groove 123 at its lower end. The guide groove 123 extends horizontally through the lower side of the multi-faceted base 12, so that the multi-faceted groove 111 communicates with the interior of the multi-faceted base 12. The guide hole 122 and the guide groove 123 form a guide channel.

[0044] The number of faces of the multi-faceted pool 11 and the multi-faceted base 12 correspond. The specific number of faces can be set according to the actual situation. In this embodiment, the multi-faceted pool 11 has six faces, and the corresponding multi-faceted base 12 has six faces.

[0045] like Figures 5-7As shown, the pressing assembly 3 includes a multi-faceted ring 31, multiple sets of insert rods 32, and an inner edge ring 33. The inner edge ring 33 is located inside the multi-faceted ring 31. The multiple sets of insert rods 32 are located between the multi-faceted ring 31 and the inner edge ring 33, and are bolted to the multi-faceted ring 31 and the inner edge ring 33 at both ends. Each set of insert rods 32 corresponds to a multi-faceted tube 21 and passes through the corresponding multi-faceted tube 21. The number of insert rods 32 in each set of insert rods 32 is preferably such that the inserted multi-faceted tube 21 remains stable. In this embodiment, the number of insert rods 32 in each set is four. The number of faces of the multi-faceted ring 31 corresponds to the number of faces of the multi-faceted base 12. In this embodiment, the number of faces of the multi-faceted ring 31 is six.

[0046] The multifaceted ring 31 includes multiple side rods 311. Each side rod 311 has a transverse groove 3111 at one end in the middle, and the other end is bent towards the inner ring 33 to form a locking block 3112 that matches the transverse groove 3111. This allows the locking block 3112 at the other end of each side rod 311 to be inserted into the transverse groove 3111 at one end of the adjacent side rod 311 and bolted together, thereby connecting multiple side rods 311 end to end to form a closed polyhedron. In this embodiment, since the multifaceted ring 31 has six sides, there are six corresponding side rods 311, and the bending angle of the other end of each side rod 311 is 120°. Each side rod 311 also has multiple sliding grooves 3113 on its upper side, corresponding to the number of insertion rods 32 in each group, so that the ends of the insertion rods 32 are inserted into the sliding grooves 3113 and bolted together, facilitating the disassembly of the side rods 311.

[0047] like Figure 2 As shown, two pairs of lifting cylinders 7 are arranged opposite each other. One pair of lifting cylinders 7 is bolted to the bottom of the multifaceted pool 11 and located inside the multifaceted base 12, with its drive end bolted to the lower side of the inner edge ring 33. The other pair of lifting cylinders 7 is bolted to the bottom of the lifting assembly 4, with its drive end bolted to the lower side of a pair of opposing side rods 311. The two pairs of lifting cylinders 7 drive the multifaceted ring 31 and the inner edge ring 33 to move up and down, thereby driving the multiple multifaceted tubes 21 above to move up and down, thus cooperating with the multifaceted tubes 21 below to loosen or clamp the quartz tube 8. The lifting cylinders 7 are waterproof and can be either hydraulic or pneumatic, depending on the actual situation.

[0048] like Figures 8-10As shown, the multifaceted tube 21 includes a hollow multifaceted tube body 211. Multiple limiting holes 22 are formed on any two opposite sides of the multifaceted tube body 211. A drainage hole 221 is also formed in the middle of each limiting hole 22. A step 222 is formed between the end of the drainage hole 221 and the end of the corresponding limiting hole 22. The limiting holes 22, drainage holes 221, and steps 222 constitute a clamp. The drainage hole 221 communicates with the hollow part of the multifaceted tube body 211, so that the limiting holes 22 and drainage holes 221 in a pair of opposite clamps are all connected. The diameter of the limiting holes 22 in a pair of opposite clamps matches the outer wall diameter of the same quartz tube 8, and the diameter of the drainage holes 221 in the corresponding clamp matches the inner wall diameter of the same quartz tube 8. This allows the steps 222 in the clamp to match the ends of the quartz tube 8 and to abut against the ends of the quartz tube 8. The clamps on any pair of opposing surfaces are of different sizes than those on other opposing surfaces, in order to match quartz tubes of different specifications. A limiting cylinder 23 is fixedly connected to each limiting hole 22 on any pair of opposing surfaces. The inner diameter of the limiting cylinder 23 is the same as the diameter of the corresponding limiting hole 22, thus limiting the quartz tube 8 and improving stability. The diameter of the guide hole 122 is larger than the largest diameter limiting cylinder 23 on the multifaceted tube body 211.

[0049] Multiple insertion holes 24 are provided between any adjacent surfaces. The number of insertion holes 24 matches the number of insertion rods 32 in each group. The insertion holes 24 are connected to the middle of the multi-faceted tube body 211, thereby forming multiple pairs of oppositely arranged insertion holes 24 to facilitate the insertion of insertion rods 32.

[0050] In this embodiment, the multifaceted tube body 211 is a hollow hexagonal tube with six faces, forming three pairs of opposing faces and three pairs of opposing insertion holes 24. The limiting holes 22, drainage holes 221, and steps 222 on any pair of opposing faces are different in specifications from those on the other two pairs of opposing faces, thus enabling the multifaceted tube body 211 to accommodate various specifications of quartz tubes 8. By inserting the insertion rod 32 into the insertion holes 24 at different positions, the limiting holes 22 on different faces are aligned with the multifaceted base 12.

[0051] like Figure 4 and Figure 8 As shown, each fixed cover 13 includes a multifaceted block 131 and an L-shaped cover plate 132. The multifaceted block 131 is fixedly connected to the vertical portion of the cover plate 132 and is located on the side away from the horizontal portion of the cover plate 132. The horizontal portion of the cover plate 132 is bolted to the multifaceted base 12. Multifaceted holes 25 matching the multifaceted blocks 131 are also provided at both ends of the multifaceted tube body 211 for the multifaceted blocks 131 to be inserted to restrict the movement of the multifaceted tube body 211. At the same time, the vertical portion of the cover plate 132 is also bolted to the end of the multifaceted tube body 211 to further fix the multifaceted tube body 211.

[0052] like Figure 2 As shown, each lifting assembly 4 includes an L-shaped fixing plate 41 and a lead screw assembly 42. The horizontal portion of the fixing plate 41 is fixedly connected to the outer wall of any one side of the multi-faceted pool 11, and the vertical portion is fixedly connected to the lead screw assembly 42 on the side facing the multi-faceted pool 11. The lead screw assembly 42 is a conventional technical means and will not be described in detail here.

[0053] like Figure 2 and Figures 11-12 As shown, the grinding assembly 5 includes a lifting plate 51, a connecting plate 52, a grinding component 53, and a driving component 54. The connecting plate 52 is bolted to the upper side of the lifting plate 51, and both ends of the lifting plate 51 are bolted to a pair of lead screw assemblies 42. The driving component 54 is located on the upper side of the connecting plate 52, and the upper end of the grinding component 53 passes through the connecting plate 52 and is connected to the driving component 54 for transmission.

[0054] The grinding component 53 includes multiple sets of grinding rods 531, which are correspondingly positioned directly above each multifaceted tube body 211. The number of grinding rods 531 in each set corresponds to the number of upper limit holes 22 on any face of the multifaceted tube body 211. The grinding rods 531 pass through and are rotatably connected to the connecting plate 52. A gear 533 is fixedly connected to the upper end of the grinding rod 531, and a grinding head 532 is detachably connected to the lower end, such as by bolt or thread connection, for easy replacement (this is a conventional technical method and will not be elaborated further). The gears 533 are located on the upper side of the connecting plate 52 and are meshed with each other. Each grinding rod 531 is also fixedly connected to a limit ring 534, which is located on the lower side of the connecting plate 52 and restricts the up and down movement of the grinding rod 531.

[0055] A liquid guiding hole (not shown in the figure) is also provided inside the grinding rod 531. The upper end of the liquid guiding hole passes through the upper end of the grinding rod 531, and the lower end passes through the side wall of the grinding rod 531 near the grinding head 532. Cooling liquid, such as coolant or water, can be supplied to the liquid guiding hole inside the rod body by connecting a cooling liquid supply line to the upper end of the grinding rod 531. When the grinding head 532 is working, the cooling liquid is transported to the grinding head 532 for cooling.

[0056] The driving component 54 includes multiple transmission wheels 541, multiple transmission rods 542, and a motor 543 bolted to the connecting plate 52. The transmission wheels 541 are rotatably connected to the upper side of the connecting plate 52. Adjacent sets of gears 533 mesh with each other at their lower parts. Each transmission wheel 541 has a tapered connection to one end of a transmission rod 542 at its upper part, and the other end of the transmission rod 542 is tapered to the drive end of the motor 543. Thus, the motor 543 drives the multiple transmission rods 542 and multiple transmission wheels 541 to rotate, thereby driving the corresponding grinding rod 531 to rotate. Driven by the lead screw assembly 42, the rod moves downwards and extends into the corresponding quartz tube 8 to grind the inner wall of the quartz tube 8. Multiple limiting rings (not shown in the figure) also extend from the connecting plate 52 for the transmission rods 542 to pass through, thereby restricting the movement of the transmission rods 542.

[0057] like Figure 2 and Figure 13 As shown, a pair of limiting components 6 are bolted to both sides of the vertical portion of a pair of fixed plates 41. Each limiting component 6 includes multiple support rods 61 and multiple sets of limiting rods 62. The ends of adjacent support rods 61 are bolted together, and the support rods 61 are bolted to the fixed plates 41. The fixed plates 41 have multiple pairs of spaced bolt holes 411 on the sides corresponding to the support rods 61, which facilitates adjustment of the installation height of the multiple support rods 61. The number of each set of limiting rods 62 corresponds to each set of grinding rods 531. One end of each limiting rod 62 is fixedly connected to the inner side of the support rod 61, and the other end has a positioning hole 621 that matches the designated location of the grinding rod 531, allowing the corresponding grinding rod 531 to pass through, thereby further improving the stability of the grinding rod 531 when rotating.

[0058] The adjacent support rods 61 can move vertically after the bolts are removed. In this embodiment, each limiting component 6 is provided with a pair of support rods 61, and the ends of the adjacent support rods 61 are respectively provided with vertical grooves and vertical blocks 611 (see...). Figure 13 The support rods are connected by bolts. If the bolts at both ends of the support rod 61 are removed, each support rod 61 can move up and down.

[0059] A method for grinding the inner hole of a quartz tube includes the following steps:

[0060] S1. First, adjust the multifaceted tube body 211 on each connecting surface 121, and place the pair of limiting cylinders 23 to be used vertically so that the limiting cylinders 23 are inserted into the corresponding guide holes 122. Then, embed the corresponding pair of multifaceted blocks 131 into the multifaceted holes 25 at both ends of the multifaceted tube body 211, and connect the ends of the multifaceted tube body 211 and the connecting surface 121 with the cover plate 132 bolts.

[0061] S2. Based on step S1, the lower end of the quartz tube 8 to be polished is inserted through the limiting cylinder 23 into the limiting hole 22, so that the lower end of the quartz tube 8 abuts against the step 222 of the corresponding limiting hole 22.

[0062] S3. Based on step S2, adjust the upper multi-faceted tube body 211, select a pair of limiting cylinders 23 of the same specification as in step S1 and place them one above the other. Then, insert an adjusted multi-faceted tube body 211 into each set of insert rods 32, and then bolt the two ends of the side rod 311 corresponding to the set of insert rods 32 to the ends of the adjacent side rods 311. Finally, bolt the set of insert rods 32 to the sliding groove 3113 of the side rods 311.

[0063] S4. Based on step S3, activate two pairs of lifting cylinders 7. Drive the multi-faceted ring 31, inner edge ring 33 and multiple multi-faceted tube bodies 211 downward through the driving end of the lifting cylinders 7, so that the limiting cylinder 23 directly below the multi-faceted tube body 211 is inserted into the upper end of the quartz tube 8 and enters the limiting hole 22 until it abuts against the step 222 of the corresponding limiting hole 22, thereby clamping the quartz tube 8 and closing the lifting cylinders 7.

[0064] S5. Based on step S4, start motor 543. Motor 543 drives multiple transmission rods 542 and multiple transmission wheels 541 to rotate, thereby driving the corresponding grinding rod 531 to rotate. At the same time, start a pair of lead screw assemblies 42. The lead screw assemblies 42 drive the grinding assembly 5 to move downward. The grinding rod 531 moves axially downward along the positioning hole 621, thereby entering the quartz tube 8. The grinding head 532 grinds the inner wall of the quartz tube 8.

[0065] S6. Based on step S5, during the grinding process of the grinding head 532, cooling liquid is injected into the liquid guide hole through the liquid supply pipeline, so that the cooling liquid flows from the lower end of the liquid guide hole to the grinding head 532 and the inner wall of the quartz tube 8, and cools the grinding head 532 and the inner wall of the quartz tube 8. Then, the cooling liquid mixes with the grinding debris and continues to flow downward to the multifaceted tube body 211 on the connecting surface 121. Then, it flows through the lower limiting cylinder 23 directly below the multifaceted tube body 211 to the corresponding guide hole 122, flows through the guide groove 123 of the corresponding guide hole 122 to the multifaceted pool 11, and finally flows out through the liquid outlet hole 112.

[0066] In addition to flowing out from the bottom limiting cylinder 23, some of the coolant in the multifaceted tube body 211 will also splash into the limiting cylinder 23 adjacent to the bottom limiting cylinder 23, and flow to the multifaceted base 12 and the multifaceted groove 111 respectively. The coolant in the multifaceted groove 111 will flow to the multifaceted pool 11 through the guide groove 123, and mix with other coolant to flow out from the outlet hole 112.

[0067] S7. Based on step S6, after the quartz tube 8 is polished, the lead screw assembly 42 drives the polishing assembly 5 to move upward, causing the polishing head 532 to disengage from the quartz tube 8. Then, the lead screw assembly 42 and motor 543 are shut off, and the input of cooling liquid into the guide orifice is stopped. Next, the lifting cylinder 7 is activated, and its drive end moves the multifaceted ring 31, inner edge ring 33, and multiple multifaceted tube bodies 211 upward until the multifaceted tube bodies 211 disengage from the upper end of the quartz tube 8. Finally, the polished quartz tube 8 is removed.

[0068] S8. Based on step S7, if it is necessary to continue polishing quartz tubes 8 of the same specification, simply repeat the operation according to steps S2 and S4-S7 to achieve batch polishing of quartz tubes 8 in one go.

[0069] S9. Multiple quartz tubes of different specifications can be polished simultaneously. First, disconnect the connection between the multifaceted tube body 211 and the fixing cover 13 on the connecting surface 121. Flip the multifaceted tube body 211 over and place the pair of limiting cylinders 23 to be used vertically, so that the limiting cylinder 23 directly below the multifaceted tube body 211 is inserted into the corresponding guide hole 122. Then, bolt the multifaceted tube body 211 to the fixing cover 13. The number of flipped multifaceted tube bodies 211 can be adjusted according to actual needs.

[0070] S10. Based on step S9, remove the bolt connection at the end of the side rod 311 and the bolt connection between the insert rod 32 and the side rod 311, take out the side rod 311 horizontally, then pull out the upper multi-faceted tube body 211 from the insert rod 32, and flip the multi-faceted tube body 211 so that the pair of limiting cylinders 23 to be used are placed vertically, then insert them again through the insert rod 32, and finally re-bolt the side rod 311 and bolt the insert rod 32 to the side rod 311.

[0071] S11. Based on step S10, replace the grinding head 532 with the corresponding new specification quartz tube 8.

[0072] S12. Based on step S11, repeat the operation according to steps S2 and S4-S7.
