[0021] See also Figure 1-4 As shown, the quartz tube inner wall polishing device of the embodiment of the utility model includes a support frame 1 and a toggle mechanism 7. The toggle mechanism 7 is arranged inside the support frame 1. A travel groove 2 is opened on one side of the support frame 1, and a straight rack 6 is fixedly connected to the inner bottom of the travel groove 2.

[0022] See also Figure 3 、 4 As shown, the toggle mechanism 7 includes a toggle frame 71, a groove 72 is provided at the bottom of the toggle frame 71, a gear 73 is provided inside the groove 72, and a rotating shaft 74 and a square shaft 75 are fixedly connected on both sides of the gear 73. The rotating shaft 74 is rotatably plugged into the inner wall of the groove 72, the gear 73 is meshed with the spur rack 6, and the other end of the square shaft 75 is sleeved with a grinding roller 76. A corresponding through hole 77 is provided on the outer wall of the toggle frame 71 corresponding to the grinding roller 76. A number of rubber blocks 78 are fixedly embedded on the outer wall of the toggle frame 71 close to the grinding roller 76, and a support plate 79 is fixedly connected to the top of the toggle frame 71.

[0023] The inner top of the travel groove 2 is provided with a corresponding support groove 3 corresponding to the support plate 79, and the support plate 79 is slidably inserted into the inside of the support groove 3; and a through groove 4 is provided through the inner top of the support groove 3. The sliding of the support plate 79 inside the support groove 3 can drive the toggle mechanism 7 as a whole to slide along the travel groove 2 inside the support frame 1. The opening of the through groove 4 can make the toggle block 712 on the toggle mechanism 7 inserted into the inside of the support frame 1 flip upward under the elastic force of the torsion spring and be located inside the through groove 4, which is convenient for toggling the toggle mechanism 7.

[0024] An adapted shaft groove 5 is provided on the inner wall of the travel groove 2 corresponding to the rotating shaft 74 , which can effectively make the toggle mechanism 7 more stable when sliding in the travel groove 2 inside the support frame 1 .

[0025] An open groove is provided on the inner wall of the through hole 77 to facilitate the grinding roller 76 to pass through the through hole 77 and be sleeved on the square shaft 75.

[0026] A plurality of rubber clamping blocks 78 are arranged around the through hole 77 at equal intervals, so that the rubber clamping blocks 78 can effectively clamp the quartz tube.

[0027] A flip groove 710 is provided at the top of the support plate 79, and a toggle block 712 is hinged to the inside of the flip groove 710 through a pin shaft 711. A torsion spring is sleeved on the shaft wall of the pin shaft 711, and the two ends of the torsion spring are respectively connected to the toggle block 712 and the inner wall of the flip groove 710, so that the elastic force of the torsion spring can drive the toggle block 712 to flip upward 90°.

[0028] In the initial state, the toggle block 712 on the support plate 79 is turned upward by 90° under the elastic force of the torsion spring.

[0029] During use, the quartz tube to be polished is sleeved on the roller wall of the polishing roller 76 in the single-group toggle mechanism 7, and the end of the quartz tube is clamped between the multiple rubber blocks 78 on the toggle frame 71, so that the quartz tube is connected to the toggle frame 71.

[0030] Insert the support plate 79 in the toggle mechanism 7 with the quartz tube into the support groove 3. When the support plate 79 is inserted into the support groove 3, the hinged toggle block 712 is turned and folded toward the inside of the flip groove 710 under the resistance of the inner top wall of the support frame 1. Figure 1 As shown in the toggle mechanism 7 on the right side, as the support plate 79 is continuously inserted, when the toggle block 712 is located inside the through slot 4, the toggle block 712 is turned upward by 90° under the elastic force of the torsion spring, as shown in the attached Figure 1 As shown in the toggle mechanism 7 on the left side, the support plate 79 and the toggle frame 71 can be driven to move along the support frame 1 by the toggle block 712.

[0031] As the toggle frame 71 moves inside the stroke groove 2, the gear 73 inside the toggle frame 71 will contact and mesh with the spur rack 6. At this time, the toggle frame 71 continues to move, and the gear 73 will rotate inside the toggle frame 71. The gear 73 can drive the grinding roller 76 to rotate when rotating. Since the quartz tube is connected to the toggle frame 71, the quartz tube is relatively stationary relative to the grinding roller 76. The grinding roller 76 can grind the inner wall of the quartz tube when rotating. After grinding is completed, the quartz tube can be directly pulled out.

[0032] The above shows and describes the basic principles of the present invention. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the scope of protection of the present invention.
