[0020] Example

[0021] Please refer to Figure 1-Figure 3 The present invention proposes a glass polishing machine, comprising an upper frame 1 and a lower frame 2 that slide longitudinally relative to each other, the upper frame 1 is equipped with a circular upper plate 3, the lower frame 2 is equipped with a lower plate 6, the circular upper plate 3 is rotatably equipped with an extension plate 4, the extension plate 4 is stretched out and can be spliced ​​with the circular upper plate 3 to form a new rectangular upper plate 5, the upper frame 1 and the lower frame 2 are close to each other so that the lower plate 6 can grind the glass adsorbed by the rectangular upper plate 5; in this solution, the upper frame 1 can be moved toward the lower frame 2 to make the upper plate and the lower plate 6 close to each other, and when dealing with circular glass grinding, it can be directly adsorbed through the circular upper plate 3, when it is necessary to grind rectangular glass, because the four corners of the rectangular glass may exceed the circular upper plate 3, the adsorption area of ​​the circular upper plate 3 is expanded by the extension plate 4, so that the four corners of the rectangular glass can also be supported, so the present application can cope with the effect of grinding different glasses.

[0022] In a specific embodiment, refer to Figure 2 , Figure 3 The circular upper plate 3 and the extension plate 4 are connected by a hinge 7; in this solution, the hinge 7 includes two joints and a pull rod, and the two ends of the pull rod are rotatably connected to the two joints respectively. The two joints are respectively installed on the circular upper plate 3 and the extension plate 4. One extension plate 4 is connected using at least two hinges 7, which can facilitate the extension plate 4 to be flipped upward and stored above the circular upper plate 3 when not in use.

[0023] In a specific embodiment, refer to Figure 2 , Figure 3A card plate 8 is rotatably installed on the circular upper disk 3. After the extension plate 4 is flipped relative to the circular upper disk 3, the card plate 8 can be rotated to contact the upper surface of the extension plate 4 to limit the position; the card plate 8 set on the circular upper disk 3 can be rotated relative to the circular upper disk 3. When the extension plate 4 needs to be flipped, the card plate 8 needs to be rotated and stored just above the circular upper disk 3. At this time, the extension plate 4 can be flipped. When the extension plate 4 is flipped, the card plate 8 is rotated again so that the card plate 8 is located above the extension plate 4 and contacts the upper surface of the extension plate 4, which can limit the extension plate 4 from flipping upward. The hinge 7 needs to pull the extension plate 4 so that the lower surface of the extension plate 4 and the lower surface of the circular upper disk 3 maintain a plane.

[0024] In a specific embodiment, refer to Figure 1 , Figure 2 The upper frame 1 includes an upper bracket 11 and a lower bracket 12, and the upper bracket 11 and the lower bracket 12 are fixedly connected by four straight rods 13. Sliders 31 are installed on both sides of the circular upper plate 3, and slide rails 121 are arranged on both sides of the lower bracket 12. The circular upper plate 3 can move horizontally on the slide rails 121 through the sliders 31; in this scheme, the guide rails arranged on the lower bracket 12 are in the form of slide grooves, and the two slides 31 installed above the circular upper plate 3 are in the shape of flat plates, which can prevent the circular upper plate 3 from rotating and causing the glass to deviate.

[0025] In a specific embodiment, refer to Figure 1 , Figure 2 The upper bracket 11 is provided with a moving block 91 through a screw mechanism 9, and the moving direction of the moving block 91 is parallel to the guide of the slide rail 121. The moving block 91 is connected to the circular upper plate 3 through a connecting component 10; the screw mechanism 9 installed on the upper bracket 11 can drive the moving block 91 to move horizontally, and its moving direction is the same as the guide of the slide rail 121. The moving block 91 can drive the circular upper plate 3 to translate along the slide rail 121 through the connecting component 10, thereby making the circular upper plate 3 translate relative to the lower plate 6 for sufficient polishing.

[0026] In a specific embodiment, refer to Figure 2The connecting assembly 10 includes a first connecting body 101 and a second connecting body 102, a connecting rod 103 is movably connected between the first connecting body 101 and the second connecting body 102, and the second connecting body 102 is rotatably connected to a connecting piece 104, and the connecting piece 104 is connected to the upper surface of the circular upper plate 3 by bolts; in this scheme, the function of the connecting assembly 10 is to pull the circular upper plate 3 to translate, and the connecting assembly 10 needs to have a certain angle with the circular upper plate 3 when pulling, and at the same time, the moving block 91 is reciprocating, and the connecting rod 103 needs to have In order to achieve shortening effect, the first connector 101 and the second connector 102 in the present application are both provided with movable space. When the end of the connecting rod 103 passes through the first connector 101 or the second connector 102, it is located in the movable space and limited by a nut. The end of the connecting rod 103 can move in the movable space. Then, the length of the connecting rod 103 between the first connector 101 and the second connector 102 can be changed, which can prevent the connecting rod 103 from maintaining a certain angle with the circular upper plate 3, thereby improving the translation effect of the circular upper plate 3.

[0027] In a specific embodiment, refer to Figure 1 The four corners of the lower bracket 12 are connected to the lower frame 2 through cylinders 13. The lower frame 2 is provided with an upright guide rod 14, and the lower bracket 12 is installed with a sleeve 15 sleeved on the guide rod 14. In this solution, the driving process of the four cylinders 13 needs to be consistent to ensure that the entire upper frame 1 can remain horizontal, and the cooperation between the guide rod 14 and the guide sleeve can improve the stability of the upper frame 1 when moving downward.
