[0025] In this embodiment, in order to solve the problems that the existing glass product 5 processing positioning fixture cannot be used in multiple specifications generally and cannot accurately make the center of the glass product 5 concentric with the main shaft, therefore, in this solution, a positioning plate assembly is provided between the side plate and the glass product 5 to sandwich and limit the glass product 5, so as to mark and define the center points at both ends of the glass product 5, and further lay a foundation for making the center of the glass product 5 concentric with the center of the main shaft in the follow - up.

[0026] Specifically, the glass processing positioning fixture mainly includes a bottom plate 4, a first side plate 2, a second side plate 7, a third side plate 8 and a positioning plate assembly. Among them, the positioning plate assembly consists of a first positioning plate 3 and a second positioning plate 6.

The main function of the positioning plate assembly is to closely adhere to both ends of the glass product 5, and at the same time, the centers of the first positioning plate 3 and the second positioning plate 6 coincide with the center points at both ends of the glass product 5, so as to mark and define the centers at both ends of the glass product 5.

[0027] It should be noted that the glass product 5 in this solution is stacked by multiple glass sheets.

[0028] Please refer with emphasis to Figures 1-2, the first side panel 2 and the second side panel 7 are both provided with a side panel center hole 12 in the middle; a plurality of adjustment holes 14 are respectively provided at both ends of the bottom panel 4, and the multiple adjustment holes 14 at both ends are respectively located directly below the first side panel 2 and the second side panel 7; the front and rear ends of the inner sides of the first side panel 2 and the second side panel 7 are fixedly connected with side panel positioning columns 13 extending in the left and right directions; the two side panel positioning columns 13 are symmetrically arranged on opposite sides of the side panel center hole 12; the first positioning plate 3 and the second positioning plate 6 are both provided with a slot 24 extending in the up and down direction and open on the lower side that matches the side panel positioning column 13, and the two side panel positioning columns 13 are respectively inserted into the two slots 24 to position the positioning plate center hole 10 concentrically with the corresponding side panel center hole 12.

[0029] In this embodiment, an adjustable nut is installed in the adjustment hole 14. The height of the second side panel 7 is adjusted by adjusting the nut in the adjustment hole 14 so that the center hole 12 of the side panel is concentric with the center point of the glass product 5. At the same time, the height of the first side panel 2 is adjusted in the same way. The side panel positioning column 13 is fixedly matched with the slots matching the side panel positioning columns 13 provided on the first positioning plate 3 and the second positioning plate 6, so that the center positioning hole 12 of the side panel, the center hole 10 of the positioning plate, and the center of the glass product 5 are concentric.

[0030] Please refer to Figure 2 A U-shaped groove is provided on the upper surface of the bottom plate 4 near the side of the third side plate 8, and a positioning baffle 9 is slidably installed on the U-shaped groove. The positioning baffle 9 is relatively parallel to the third side plate 8, and the positioning baffle 9 is provided with four fixing holes 11 respectively located at the four vertex corners of the same rectangle; the third side plate 8 is provided with four connecting holes 26 respectively located at the four vertex corners of the same rectangle, and the four connecting holes 26 are respectively aligned concentrically with the four fixing holes 11 in a one-to-one manner.

[0031] In this embodiment, the limit baffle 9 can slide back and forth through the U-shaped groove, and can match the loading of glass of different sizes. A screw is provided at the bottom of the limit baffle 9, and the movable limit baffle 9 can be fixed by installing the nut, so that it can adapt to different models of glass products 5, so that the center of the glass product 5 can be concentric with the center hole 12 of the side panel and the center hole 10 of the positioning plate.

[0032] Please refer to Figures 1-2 A positioning plate clamping groove 20 is opened on the outer side of the middle part of the first positioning plate 3 and the second positioning plate 6. The positioning plate clamping groove 20 is connected to the center hole 10 of the positioning plate. The upper and lower sides of the positioning plate clamping groove 20 are respectively provided with a parallel and aligned first positioning bar 15 and a second positioning bar 16.

[0033] In this embodiment, the first positioning plate 3 and the second positioning plate 6 are each provided with two limiting fixing strips (a first positioning strip 15 and a second positioning strip 16) and a positioning plate clamping groove 20. The two limiting fixing strips are connected to the first positioning plate 3 and the second positioning plate 6 by screws, and the holes through which the screws pass on the two limiting fixing strips are waist-shaped holes. The spacing between the two limiting fixing strips can be adjusted left and right.

[0034] Please refer to Figure 3 and Figure 4 , Figure 3 This is a reference diagram of the loading and clamping mechanism provided by the present invention in use. Figure 4 This is a three-dimensional exploded schematic diagram of the local structure of the loading and clamping mechanism provided by the present invention, as shown in FIG. Figure 3 and Figure 4 As shown, the glass processing loading and clamping mechanism provided by the present invention includes the above-mentioned positioning fixture, clamp 1, left spindle 17 and right spindle 19. It should be emphasized that the first side plate 2 and the second side plate 7 are both provided with a first alignment groove 25 extending in the vertical direction and open on the upper side.

[0035] A positioning block 18 is provided at the clamping end of the clamp 1, and the contour of the positioning block 18 matches the contour of the first alignment groove 25; a first E-type block 21 and a second E-type block 22 are respectively provided at the opposite ends of the left spindle 17 and the right spindle 19; the first E-type block 21 and the second E-type block 22 are both provided with a second alignment groove 27 extending in the up-down direction and open on the upper side; the contour of the positioning block 18 matches the contour of the second alignment groove 27.

[0036] In this embodiment, a positioning block 18 is provided at the jaw end of the clamp. The purpose of this design is that after the first positioning plate 3 (or the second positioning plate 6) is matched with the E-type block of the right main shaft 19, the glass product 5 as a whole can be rocked back and forth. At this time, the left main shaft 17 is driven to move toward the right main shaft 19, and the positioning block 18 placed on the clamp 1 is placed against the first E-type block 21 (or the second E-type block 22) for initial positioning. Then, after the main shaft is displaced, the E-type blocks (the first E-type block 21 and the second E-type block 22) can be fully matched with the positioning block 18.

[0037] See also Figures 3-4 The first E-shaped block 21 and the second E-shaped block 22 are both provided with a positioning step 23 in the middle; the contour of the accommodation space formed by the combination of the positioning plate clamping groove 20, the first positioning bar 15 and the second positioning bar 16 matches the outer contour of the positioning step 23.

[0038] In this embodiment, the spindle E-type block (the first E-type block 21 and the second E-type block 22) is fixed to the spindle (the left spindle 17 and the right spindle 19) by fixing the positioning pins. There is a raised positioning step 23 on the top of the E-type block. The two sides of the positioning step 23 are a plane, and the other two sides are arcs and the whole is conical. The purpose of this design is that the two sides are planes and can be stuck in the two limiting fixing strips (the first positioning strip 15 and the second positioning strip 16) of the positioning plate (the first positioning plate 3 and the second positioning plate 6) so that they will not rotate after assembly. The other two surfaces are arcs and conical at the same time. In this way, when the E-type block cooperates with the positioning plate clamping groove 20, the friction can be reduced, the service life can be improved, and it is more conducive to assembly.

[0039] The following briefly describes the working principle of the loading and clamping mechanism. When clamping the glass, first align the first and second positioning bars 15, 16 via the positioning steps 23, adjust the spacing, and secure them to the second positioning plate 6. Simultaneously, the first positioning plate 3 is installed with the positioning bars in the same manner. Next, the first positioning plate 3 is secured to the side plate positioning posts 13 on the first side plate 2, ensuring that the positioning plate center hole 10 is concentric with the side plate center hole 12. Simultaneously, the second positioning plate 6 and the second side plate 7 are installed in the same manner. Several stacked glass products 5 are then placed on the base plate 4. The height of the second side plate 7 is adjusted by adjusting the nuts in the base side plate height adjustment holes 14, ensuring that the side plate center hole 12 is concentric with the center point of the glass product 5. Simultaneously, the height of the first side plate 2 is adjusted in the same manner. The front and rear position of the stopper 9 is then adjusted using the U-shaped slots on the base plate 4, ensuring that the glass product 5 is close to the first and second side plates 2, 7. Finally, the glass is clamped by the clamp 1 through the first and second positioning plates 3, 6, and removed from the positioning fixture.

[0040] When the glass is loaded onto the spindle, the first E-shaped block 21 and the second E-shaped block 22 are first completely fixed on the left spindle 17 and the right spindle 19 respectively through the positioning pins; then the glass product 5 taken out by the clamp 1 is clamped and fixed through the matching of the positioning plate clamping groove 20 and the positioning step 23; then the left spindle 17 is driven to move toward the right spindle 19, and the positioning block 18 on the clamp 1 is used to approach the first E-shaped block 21 (or the second E-shaped block 22) for positioning, and then the left spindle 17 is displaced through the matching of the positioning plate clamping groove 20 and the positioning step 23 to clamp the glass product 5; finally, the left spindle 17 and the right spindle 19 rotate simultaneously, and the brushes on both sides rotate to polish the glass to its starting position.

[0041] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
