[0038] In the description of the present application, unless otherwise explicitly defined, the words such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0039] It can be understood that, with reference to Figures 1 to 4 The quartz tube grinding tool of the first aspect embodiment of the present application comprises a support mechanism 100, a mounting seat 200 and a paraffin block 310. The support mechanism 100 comprises a guide block 110 and a support tube 120. The guide block 110 is provided with a positioning groove 111 and a tapered groove 112. The positioning groove 111 is in abutment and communication with the tapered groove 112. The quartz tube 400 is detachably connected in the positioning groove 111. The tapered groove 112 is used to guide the support tube 120 to extend into the quartz tube 400. The outer diameter of the support tube 120 matches the inner diameter of the quartz tube 400. The mounting seat 200 is provided with a through hole 210. The diameter of the through hole 210 matches the outer diameter of the quartz tube 400. The quartz tube 400 is arranged in the through hole 210. Both ends of the quartz tube 400 protrude from the mounting seat 200. The paraffin block 310 is arranged between the mounting seat 200 and the side wall of the quartz tube 400 protruding from the mounting seat 200. The paraffin block 310 surrounds the quartz tube 400. The paraffin block 310 is used to fix the quartz tube 400 in the through hole 210.

[0040] The guide block 110 is provided with the positioning groove 111 and the tapered groove 112. The positioning groove 111 is in abutment and communication with the tapered groove 112. By inserting the quartz tube 400 into the positioning groove 111 and then inserting the support tube 120 into the tapered groove 112, the tapered groove 112 can guide the support tube 120 to extend into the quartz tube 400. The support tube 120 can abut against the inner side wall of the quartz tube 400. Then the quartz tube 400 is taken out from the positioning groove 111 and arranged in the through hole 210. The inner side wall of the through hole 210 can abut against the outer side wall of the quartz tube 400 to enhance the support effect on the quartz tube 400 and reduce the possibility of end face collapse of the quartz tube 400.

[0041] Both ends of the quartz tube 400 protrude from the mounting seat 200. The paraffin block 310 is arranged between the mounting seat 200 and the side wall of the quartz tube 400 protruding from the mounting seat 200. The paraffin block 310 can fix the quartz tube 400 in the through hole 210, thereby replacing the fixing by clamping with a pressing block. This can not only reduce the possibility of scratches on the side wall of the quartz tube 400, but also only need to turn over the mounting seat 200 when grinding both ends of the quartz tube 400, without the need for secondary clamping of the quartz tube 400. This can improve the processing precision of the quartz tube 400 and improve the yield.

[0042] The taper groove 112 is in abutment and communication with the positioning groove 111, so that when the support tube 120 is placed in the taper groove 112, the support tube 120 can be guided to gradually align with the quartz tube 400, and the support tube 120 can smoothly extend into the quartz tube 400, avoiding collision and jam of the support tube 120 on the end face of the quartz tube 400, and reducing the possibility of end face collapse of the quartz tube 400.

[0043] In addition, the length of the quartz tube 400 is greater than the thickness of the mounting seat 200, so that both ends of the quartz tube 400 protrude from the mounting seat 200. By arranging the molten paraffin between the mounting seat 200 and the quartz tube 400, the paraffin can be cooled and solidified to form a paraffin block 310, so that the quartz tube 400 can be fixed in the through hole 210, instead of being fixed by pressing the block, thereby preventing scratches on the side wall of the quartz tube 400, and helping to improve the processing yield of the quartz tube 400.

[0044] It should be noted that the guide block 110 is separately provided with the mounting seat 200, and by arranging the guide block 110, the support tube 120 can be conveniently extended into the quartz tube 400, and the quartz tube 400 can be conveniently taken out from the positioning groove 111 and arranged in the through hole 210, which helps to improve the feeding convenience of the quartz tube 400.

[0045] Specifically, the support tube 120 can be a glass piece, a metal piece, etc., which is not limited here. The support tube 120 is fixedly connected in the quartz tube 400, so that the support tube 120 can be ground synchronously when the quartz tube 400 is ground, which can enhance the support effect of the quartz tube 400, reduce the possibility of damage and collapse of the quartz tube 400, and improve the yield. After the quartz tube 400 is ground, the support tube 120 can be removed.

[0046] The support tube 120 can be fixed in the quartz tube 400 by interference fit, gluing, etc., which is not described one by one here.

[0047] It can be understood that, referring to Figure 2 and Figure 3 , a paraffin layer 320 is arranged between the quartz tube 400 and the support tube 120, and the paraffin layer 320 is used to fix the support tube 120 in the quartz tube 400. By arranging the paraffin layer 320 between the quartz tube 400 and the support tube 120, the support tube 120 is fixed in the quartz tube 400, which enhances the connection stability between the support tube 120 and the quartz tube 400, so that the support tube 120 can be stably abutted on the inner side wall of the quartz tube 400, preventing the position of the support tube 120 from shaking, which not only can improve the support effect of the quartz tube 400, effectively reduce the possibility of end face collapse of the quartz tube 400 due to uneven force or vibration during grinding, but also can facilitate separation of the support tube 120 from the quartz tube 400, which helps to improve the processing operation convenience of the quartz tube 400.

[0048] In addition, the paraffin layer 320 can buffer the impact force between the quartz tube 400 and the support tube 120, so that the stress of the quartz tube 400 during the grinding process can be uniformly transmitted to the support tube 120, preventing stress concentration of the quartz tube 400 and reducing the possibility of cracking of the quartz tube 400.

[0049] It should be noted that the outer diameter of the support tube 120 is smaller than the inner diameter of the quartz tube 400, so that a gap is formed between the support tube 120 and the quartz tube 400. The molten paraffin can be arranged in the quartz tube 400, and then the support tube 120 is inserted into the quartz tube 400, so that the paraffin can be cooled to form the paraffin layer 320. Not only can the paraffin layer 320 lubricate the support tube 120, but also the paraffin layer 320 can absorb the gap between the support tube 120 and the quartz tube 400, avoiding the support tube 120 from shaking in the quartz tube 400, thereby improving the support effect of the quartz tube 400 and reducing the possibility of damage caused by cracking of the quartz tube 400.

[0050] Specifically, referring to Figure 2 and Figure 3 , the paraffin layer 320 is arranged around the support tube 120. By arranging the paraffin layer 320 around the support tube 120, the connection stability between the support tube 120 and the quartz tube 400 can be enhanced, so that the stress of the support tube 120 in the quartz tube 400 is more uniform, effectively avoiding the possibility of uneven stress of the quartz tube 400 during grinding, and reducing the risk of cracking of the end face of the quartz tube 400.

[0051] At the same time, the paraffin layer 320 arranged around can fill the gap between the support tube 120 and the inner wall of the quartz tube 400, so that the quartz tube 400 and the support tube 120 are tightly connected, preventing relative displacement between the support tube 120 and the quartz tube 400 during grinding, thereby improving the precision and stability of grinding, and helping to improve the processing quality and yield of the quartz tube 400.

[0052] It can be understood that, referring to Figures 1 to 3 , the number of through holes 210 is set to be multiple, and the multiple through holes 210 are arranged at intervals. By arranging multiple through holes 210 on the mounting seat 200, multiple quartz tubes 400 can be clamped on the mounting seat 200 at the same time, improving the space utilization of the mounting seat 200, reducing the processing time and cost of unit quartz tube 400, improving the grinding efficiency of the quartz tube 400, and making the grinding process more efficient.

[0053] Specifically, referring to Figure 1 , Figure 2 and Figure 5Further comprising a positioning base 220, the mounting base 200 is provided with a first bolt 221, the first bolt 221 is in threaded connection with the positioning base 220, and the end of the quartz tube 400 can abut the end face of the positioning base 220. The first bolt 221 is provided in the mounting base 200, and the first bolt 221 is in threaded connection with the positioning base 220. By screwing the first bolt 221 into the positioning base 220, the first bolt 221 can drive the mounting base 200 to move towards the positioning base 220, so that the end of the quartz tube 400 can abut the end face of the positioning base 220, thereby driving the quartz tube 400 to slide in the through hole 210, so that one end of the plurality of quartz tubes 400 can be kept in the same plane, thereby keeping the grinding amount of the plurality of quartz tubes 400 consistent, and improving the grinding consistency of the plurality of quartz tubes 400.

[0054] It should be noted that the positions of the plurality of quartz tubes 400 in the through hole 210 are positioned by the positioning base 220, and then the positions of the plurality of quartz tubes 400 are fixed by the paraffin block 310, thereby improving the position accuracy of the quartz tube 400.

[0055] It can be understood that, referring to Figure 4 , the guide block 110 is also provided with a guide groove 113, the two ends of the guide groove 113 are respectively communicated with the positioning groove 111 and the tapered groove 112, and the diameter of the guide groove 113 matches the inner diameter of the quartz tube 400. The guide groove 113 is arranged between the positioning groove 111 and the tapered groove 112, and the support tube 120 can pass through the tapered groove 112 and the guide groove 113 in sequence. The tapered groove 112 can guide the support tube 120 to align with the guide groove 113, so that the support tube 120 can smoothly extend into the guide groove 113. The diameter of the guide groove 113 matches the inner diameter of the quartz tube 400, so that the support tube 120 can be aligned to the inner hole of the quartz tube 400 through the guide groove 113, thereby avoiding the position of the support tube 120 from being skewed, facilitating the smooth extension of the support tube 120 into the quartz tube 400, and improving the installation convenience of the support tube 120.

[0056] Specifically, referring to Figure 4 , the end of the positioning groove 111 away from the tapered groove 112 is provided with a chamfer 114 between the side wall, and the chamfer 114 is used to guide the quartz tube 400 to extend into the positioning groove 111. By providing the chamfer 114 between the end of the positioning groove 111 away from the tapered groove 112 and the side wall, the end of the positioning groove 111 away from the tapered groove 112 can form a tapered guide space, which can guide the quartz tube 400 to smoothly extend into the positioning groove 111, reduce the possibility of the quartz tube 400 being stuck at the end of the positioning groove 111, not only facilitate the installation and arrangement of the quartz tube 400, but also reduce the possibility of the end of the quartz tube 400 being damaged by collision, which helps to improve the grinding yield of the quartz tube 400.

[0057] It should be noted that the chamfer 114 can be a rounded chamfer or an inclined chamfer, which is not limited here.

[0058] It can be understood that, referring to Figure 1 and Figure 6 , the connecting frame 230 is provided with a second bolt 231, and the second bolt 231 is in threaded connection with the mounting seat 200. The connecting frame 230 is provided with a plurality of handle grooves 232, which are arranged at intervals along the circumference of the connecting frame 230. The second bolt 231 is provided in the connecting frame 230, and the second bolt 231 is in threaded connection with the mounting seat 200, so that the mounting seat 200 can be fixed on the connecting frame 230. By arranging a plurality of handle grooves 232 at intervals in the circumference of the connecting frame 230, the user can easily grasp, so as to facilitate the carrying and shifting of the mounting seat 200, and improve the convenience and efficiency of operation.

[0059] In addition, the second bolt 231 can be used to fix the mounting seat 200 on the connecting frame 230. After one end of the quartz tube 400 is ground, the second bolt 231 is unscrewed, the mounting seat 200 is turned over, and the second bolt 231 is fixed on the connecting frame 230 again to grind the other end of the quartz tube 400. Thus, the position of the mounting seat 200 can be easily adjusted, and the two ends of the quartz tube 400 can be easily ground, avoiding the secondary clamping of the quartz tube 400.

[0060] It should be noted that the number of second bolts 231 is set to be multiple, and the multiple second bolts 231 are arranged at intervals along the circumference of the connecting frame 230, so as to increase the fixing points of the mounting seat 200 and improve the reliability of the connection.

[0061] Specifically, referring to Figure 1 and Figure 6 , the outer dimension of the connecting frame 230 is greater than the outer dimension of the mounting seat 200, so that the projection of the mounting seat 200 is located in the connecting frame 230. By setting the outer dimension of the connecting frame 230 to be greater than the outer dimension of the mounting seat 200, on the one hand, a wider range of force application can be provided, so that the user can apply force more conveniently; on the other hand, during the carrying process, when the tooling needs to be rotated, turned over or the like, the larger connecting frame 230 can serve as a more stable support base, reducing the possibility of collision between the mounting seat 200 and other objects, and improving the reliability.

[0062] It can be understood that, referring to Figure 7 , the quartz tube grinding method of the second aspect embodiment of the present application is applied to the quartz tube grinding tooling of the first aspect embodiment of the present application, and the quartz tube grinding method comprises:

[0063] S100 inserts the quartz tube 400 into the positioning groove 111, and then inserts the support tube 120 into the tapered groove 112, so that the support tube 120 is fixed in the quartz tube 400;

[0064] S200 inserts the quartz tube 400 into the through hole 210, and makes both ends of the quartz tube 400 protrude from the end surface of the mounting base 200, and then arranges the paraffin block 310 between the mounting base 200 and the side wall of the quartz tube 400 protruding from the mounting base 200, so that the quartz tube 400 is fixed in the through hole 210;

[0065] S300 arranges the mounting base 200 in the grinding machine, grinds one end of the quartz tube 400, measures the length of the quartz tube 400, and then grinds the other end of the quartz tube 400;

[0066] S400 heats the paraffin block 310 to melt the paraffin block 310, so that the quartz tube 400 is taken out of the through hole 210, and the support tube 120 is taken out of the quartz tube 400.

[0067] Firstly, the quartz tube 400 is inserted into the positioning groove 111, and then the support tube 120 is inserted into the tapered groove 112, so that the support tube 120 can smoothly extend into the quartz tube 400, and then the quartz tube 400 is taken out of the positioning groove 111 and inserted into the through hole 210, and then the paraffin block 310 is arranged between the mounting base 200 and the quartz tube 400, so that the quartz tube 400 is fixed in the through hole 210, and both ends of the quartz tube 400 protrude from the mounting base 200.

[0068] Subsequently, the mounting base 200 is arranged in the grinding machine, one end of the quartz tube 400 is ground by the grinding machine, so that the one end of the quartz tube 400 is flat, then the length of the quartz tube 400 is measured, and the other end of the quartz tube 400 is ground until the length of the quartz tube 400 meets the design requirements.

[0069] Finally, the paraffin block 310 is heated to melt the paraffin block 310, so that the quartz tube 400 can be taken out of the through hole 210, and then the support tube 120 is taken out of the quartz tube 400.

[0070] By arranging the support tube 120 in the quartz tube 400, the support effect on the quartz tube 400 is enhanced, the stress concentration of the quartz tube 400 is reduced, and the possibility of cracking of the quartz tube 400 during grinding is reduced, and the quartz tube 400 is fixed in the through hole 210 by the paraffin block 310, which can prevent scratches on the side wall of the quartz tube 400, and improve the grinding quality and yield of the quartz tube 400.

[0071] In addition, the quartz tube 400 is fixed in the through hole 210 by the paraffin block 310, which not only facilitates the fixation of the quartz tube 400, but also can wrap the quartz tube 400 out of the side wall of the mounting seat 200, so as to improve the support of the quartz tube 400 and reduce the possibility of breakage of the quartz tube 400. Meanwhile, the paraffin block 310 can be melted by heating, which facilitates the dismounting of the quartz tube 400 and helps to improve the grinding convenience of the quartz tube 400.
