At this time, the upper clamping ring is pressed tightly on the quartz tubes, and the triangular shell is attached to the supporting shell;

At this time, the triangular shell fits on the supporting shell, and then the lifting platform continues to drive the grinding rod downward. At this time, the supporting shell moves downward due to the compression of the triangular shell, thereby driving the quartz tube between the lower frame ring and the upper clamping ring to move downward. During the downward movement, the push wheel on the lower frame ring will fit on the push frame and roll, thereby driving the multiple quartz tubes to move toward the multiple grinding rods respectively, so that the end of the rotating grinding rod can extend into the inner hole of the quartz tube, so as to grind the inner hole arc surface of the multiple quartz tubes at the same time, thereby improving the grinding efficiency.

[0018] 2. When the lifting platform drives the polishing rod to move down and align with the quartz tube, the upper clamping ring will move down synchronously under the drive of the lifting platform to press on multiple quartz tubes, so as to clamp and fix multiple quartz tubes between the lower frame ring and the upper clamping ring at the same time. The process does not require workers to manually fix each quartz tube, thereby effectively improving the convenience of use. At the same time, under the action of the protrusion, the two ends of the quartz tube can be fitted to limit the quartz tube, so that when the polishing rod is gradually extended into the inner hole of the quartz tube, the quartz tube will not be pushed by the polishing rod and move backward, thereby ensuring that the polishing rod and the inner hole arc surface of the quartz tube are fully in contact, that is, ensuring the polishing effect of the inner hole arc surface of the quartz tube.

[0036] A method for polishing the arc surface of the inner hole of a quartz tube is also provided, comprising the following steps:

[0037] S1: multiple quartz tubes 38 are placed in multiple lower frame rings 21, and then the lifting member drives the polishing rod 18 to move downward and align with the quartz tube 38. At this time, the upper clamping ring 20 is pressed tightly on the quartz tube 38, and the triangular shell 13 is attached to the supporting shell 6;

[0038] S2: Then the second servo motor 5 works to drive the multiple grinding rods 18 to rotate synchronously through the gear 31, and then the lifting member continues to drive the grinding rods 18 to move downward. At this time, the supporting shell 6 is pressed downward by the triangular shell 13, and the quartz tube 38 clamped between the upper clamp ring 20 and the lower frame ring 21 moves downward synchronously;

[0039] S3: During the downward movement, the push wheel 22 on the lower frame ring 21 will roll against the push frame 23, thereby driving the multiple quartz tubes 38 to move toward the multiple polishing rods 18 respectively, so that the ends of the polishing rods 18 can extend into the inner holes of the quartz tubes 38, so as to polish the inner hole arc surfaces of the multiple quartz tubes 38 at the same time.

[0040] During polishing, multiple quartz tubes 38 are placed in multiple lower frame rings 21. At this time, the protrusions 37 are attached to the ends of the quartz tubes 38 to limit the quartz tubes 38. Then, the No. 1 servo motor 3 works to drive the threaded rod 9 to rotate, so that the lifting platform 4 screwed on the threaded rod 9 can move downward. At this time, the guide seat 11 is attached to the guide rod 10 to slide, so as to assist the lifting platform 4 to move downward, so that the lifting platform 4 that moves downward drives the polishing rod 18 to move downward and align with the quartz tube 38. At this time, the triangular shell 13 is attached to the supporting shell 6, and the upper clamping ring 20 will move downward synchronously under the drive of the lifting platform 4 to press on the multiple quartz tubes 38, so as to clamp and fix the multiple quartz tubes 38 between the lower frame ring 21 and the upper clamping ring 20 at the same time. Then, the No. 2 servo motor 5 works to drive the multiple polishing rods 18 synchronously through the gear 31. The lifting platform 4 then continues to drive the polishing rod 18 to move downward. At this time, the supporting shell 6 is pressed downward by the triangular shell 13, thereby driving the quartz tube 38 between the lower frame ring 21 and the upper clamping ring 20 to move downward. During the downward movement, the push wheel 22 on the lower frame ring 21 will fit on the push frame 23 and roll, thereby driving the multiple quartz tubes 38 to move toward the multiple polishing rods 18 respectively. During this process, the guide cap 17 will fit on the surface of the pressure column 15, and the bracket 24 will fit on the inside of the supporting shell 6 and slide to guide the moving quartz tube 38. At the same time, the supporting column 26 moves down into the supporting shell 7, and the tightening spring 27 contracts and deforms, so that the downward moving supporting shell 6 will not be hindered, so that the end of the rotating polishing rod 18 can gradually extend into the inner hole of the quartz tube 38, so as to grind the inner hole arc surface of multiple quartz tubes 38 at the same time.

A method for grinding the arc surface of the inner hole of a quartz tube, used in the device for grinding the arc surface of the inner hole of a quartz tube as claimed in claim 4, characterized in that: The following steps are involved: S1: multiple quartz tubes (38) are placed in multiple lower frame rings (21), and then the lifting member drives the grinding rod (18) to move downward and align with the quartz tube (38). At this time, the upper clamping ring (20) is pressed tightly on the quartz tube (38), and the triangular shell (13) is attached to the supporting shell (6); S2: Then the second servo motor (5) works to drive the multiple grinding rods (18) to rotate synchronously through the gear (31), and then the lifting member continues to drive the grinding rods (18) to move downward. At this time, the support shell (6) is pressed downward by the triangular shell (13), and the quartz tube (38) clamped between the upper clamping ring (20) and the lower frame ring (21) moves downward synchronously; S3: During the downward movement, the push wheel (22) on the lower frame ring (21) will roll against the push frame (23), thereby driving the multiple quartz tubes (38) to move toward the multiple grinding rods (18) respectively, so that the ends of the grinding rods (18) can extend into the inner holes of the quartz tubes (38), so as to grind the inner hole arc surfaces of the multiple quartz tubes (38) at the same time.
