Detailed implementation manners

[0033] Please refer to Figure 1 In the embodiment of the present invention, a grinding device for quartz product processing includes a base 1. A cavity 21 is provided in the middle of the upper end of the base 1. A fixing mechanism for clamping a quartz product is arranged in the upper part of the inner cavity of the cavity 21. The fixing mechanism includes symmetric clamping plates 10. A moving groove 3 is provided on one side of the upper end of the base 1. A slider 4 is slidably connected in the inner cavity of the moving groove 3. The upper end of the slider 4 is drivingly connected with a grinding mechanism. A driving mechanism for driving the slider 4 to horizontally reciprocate in the inner cavity of the moving groove 3 is arranged below the moving groove 3. When the symmetric clamping plates 10 clamp and fix the quartz product, the slider 4 horizontally reciprocates within the distance between the symmetric clamping plates 10.

[0034] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5, at the middle of the lower ends of the symmetrical clamping plates 10, connecting rods 15 are fixedly connected. At the upper part of the inner cavity of the cavity 21, a turntable 2 is rotatably connected. At the middle of the upper end of the turntable 2, symmetrical horizontal grooves 9 are opened. The outer wall of the connecting rod 15 is slidably connected in the inner cavity of the horizontal groove 9. At the middle of the inner cavity of the turntable 2, a first groove 22 is opened. At the middle of the inner cavity of the turntable 2, a placing table 11 is fixedly connected. The outer wall of the placing table 11 is rotatably connected with a gear 13. In the inner cavity of the first groove 22, racks 14 which are centrosymmetric about the center position of the placing table 11 are slidably connected. The outer wall of the gear 13 meshes with the racks 14. One end of the rack 14 far from the gear 13 is fixedly connected with the connecting rod 15. One end of the rack 14 close to the gear 13 and far from the position of the moving groove 3 is drivingly connected with an electric push rod (not shown in the figure). The outer wall of the electric push rod is connected with the bottom of the inner cavity of the first groove 22. The electric push rod is used to drive the rack 14 far from the moving groove 3 to move horizontally, so as to drive the clamping plate 10 to approach the position where the placing table 11 is located through the connecting rod 15, and drive the other rack 14 to move synchronously through the rotation of the gear 13, so as to achieve the effect that the symmetrical clamping plates 10 approach the position where the placing table 11 is located synchronously. When the quartz product needs to be processed and polished, first place the quartz product on the upper end of the placing table 11, and then drive the symmetrical clamping plates 10 to approach the position where the placing table 11 is located synchronously through the electric push rod, so as to clamp and fix the quartz product through the symmetrical clamping plates 10, and then it is convenient to polish the quartz product through the polishing mechanism subsequently.

[0035] Please refer to Figure 3 , during the processing of the quartz product, it needs to be cut into appropriate sizes. In order to ensure the quality of the quartz product, the cutting surface of the quartz product needs to be polished. The polishing mechanism includes an electric telescopic push rod 5. The output end of the electric telescopic push rod 5 is drivingly connected with a U-shaped plate 6. The outer wall of the side of the electric telescopic push rod 5 far from the U-shaped plate 6 is drivingly connected with the upper end of a slider 4. At the middle of the upper end of the inner cavity of the U-shaped plate 6, a driving motor 8 is drivingly connected. The output end of the driving motor 8 is drivingly connected with a polishing block 7. One end of the polishing block 7 far from the driving motor 8 is drivingly connected with the bottom of the inner cavity of the U-shaped plate 6. That is, the electric telescopic push rod 5 is used to drive the polishing block 7 to approach the outer wall of the quartz product, and the driving motor 8 can drive the polishing block 7 to rotate so as to polish the quartz product. When the slider 4 moves horizontally in the inner cavity of the moving groove 3, it can drive the polishing block 7 to move horizontally synchronously, so as to polish the outer wall of the quartz product repeatedly.

[0036] Please refer to Figures 4 - 6 and Figure 12, a fixing plate 17 is fixedly connected to the middle of one side of the lower end of the connecting rod 15 close to the placing table 11. The lower end surface of the connecting rod 15 coincides with the lower end surface of the turntable 2. An adapting groove 20 is formed on the outer wall of the connecting rod 15 on the side far from the fixing plate 17. A driven plate 16 is vertically and slidably connected to the inner cavity of the adapting groove 20. The upper end of the driven plate 16 is elastically connected to the top of the inner cavity of the adapting groove 20 through a spring. A driven rod 23 is arranged between the driven plate 16 and the fixing plate 17. The driven rod 23 is slidably connected to the bottom of the inner cavity of the cavity 21. The symmetric driven rods 23 are elastically connected through symmetric springs. A force is applied to the driven rod 23 by the spring to move in the direction of the placing table 11. That is, when the driven rod 23 loses the blockage of the fixing plate 17, it will automatically move towards the position of the placing table 11. When the clamping plate 10 moves towards the placing table 11 along with the rack 14, it will drive the driven rod 23 to move horizontally through the cooperation of the driven plate 16 and the fixing plate 17, so that the distance between the driven rods 23 is adapted to the length of the quartz product. That is, the interval between the driven rods 23 will change with the length of the quartz product. When the length of the quartz product to be polished is larger, the distance between the symmetric driven rods 23 will also increase. When the length of the quartz product to be polished is smaller, the distance between the symmetric driven rods 23 will also decrease.

[0037] Please refer to Figure 9 , a third groove 35 is formed in the inner cavity of the base 1 close to one side of the moving groove 3. The driving mechanism includes symmetric screw rods 36. One end of the screw rod 36 is rotatably connected to the side wall of one side of the inner cavity of the third groove 35. One end of the screw rod 36 is drivingly connected to a servo motor (not shown in the figure). The third groove 35 is located below the moving groove 3. One end of the driven rod 23 close to the third groove 35 is fixedly connected to a first movable plate 37. The first movable plate 37 is slidably connected to the inner cavity of the third groove 35. That is, the horizontal movement of the driven rod 23 will synchronously drive the first movable plate 37 to move horizontally. That is, by driving the screw rod 36 to rotate through the motor, the symmetric screw rods 36 rotate in opposite directions. The middle of the lower end of the slider 4 is fixedly connected to a second movable plate 37. Symmetric through holes are formed in the side wall of the movable plate 37. The inner cavity of the through hole is slidably matched with the outer wall of the screw rod 36. That is, the rotation of the screw rod 36 will not affect the horizontal movement of the movable plate 37, and vice versa. The change in the distance between the driven rods 23 will affect the interval between the symmetric first movable plates 37.

[0038] Please refer to Figure 10, on one side of the upper part of the second movable plate 37, a first driven block 38 is vertically and slidably connected. On one side of the lower part of the second movable plate 37, far away from the first driven block 38, a second driven block 39 is vertically and slidably connected. A chute is formed in the middle of the second movable plate 37. In the inner cavity of the chute, a connecting block 40 is vertically and slidably connected. The two ends of the connecting block 40 are respectively fixedly connected to the middle parts of the first driven block 38 and the second driven block 39. The ends of the first driven block 38 and the second driven block 39, far away from the chute, are respectively threadedly connected to the upper and lower screw rods 36. That is, through the transmission cooperation between the first driven block 38 and the upper screw rod 36, the first driven block 38 and the second movable plate 37 can be driven to move synchronously towards the outer wall on one side (hereinafter replaced by "left side") of the inner cavity of the moving groove 3. Through the transmission cooperation between the second driven block 39 and the lower screw rod 36, the first driven block 38 and the second movable plate 37 can be driven to move synchronously towards the outer wall on the other side of the inner cavity of the moving groove 3 (hereinafter replaced by "right side"), so as to achieve the effect of driving the grinding block 7 to reciprocate horizontally in the inner cavity of the moving groove 3.

[0039] Please refer to Figure 11 , on the side walls of the inner cavity of the chute, two groups of symmetric positioning grooves 42 are formed. On both sides of the connecting block 40, positioning rods 41 are elastically connected. When the positioning rods 41 are located in the inner cavities of the upper symmetric positioning grooves 42, at this time, the upper end surface of the first driven block 38 is in transmission cooperation with the upper screw rod 36. That is, at this time, the second movable plate 37 drives the grinding block 7 to move horizontally towards the left side. When the positioning rods 41 are located in the inner cavities of the lower symmetric positioning grooves 42, at this time, the grinding block 7 moves horizontally towards the right side. In the middle of one side of the first movable plate 37, close to the first driven block 38, a second pushing block 44 is fixedly connected. In the middle of one side of the first movable plate 37, close to the second driven block 39, a first pushing block 43 is fixedly connected. On the inclined surfaces, at the upper end of the second driven block 39, at the lower end of the first driven block 38, far away from the connecting block 40, at the lower end of the first pushing block 43, and at the upper end surface of the second pushing block 44. When the second movable plate 37 moves towards the left side, the inclined surface of the second driven block 39 contacts the inclined surface of the first pushing block 43, so as to downwardly squeeze the position of the second driven block 39, so that the second driven block 39, the connecting block 40, and the first driven block 38 move downward, so that the positioning rods 41 move downward to the inner cavities of the lower positioning grooves 42. Through the clamping cooperation between the positioning rods 41 and the positioning grooves 42, the position of the connecting block 40 after moving is limited, so that the second driven block 39 is in transmission cooperation with the lower screw rod 36, so as to drive the second movable plate 37 to move towards the right side through the lower screw rod 36. After the inclined surface of the first driven block 38 contacts the inclined surface of the second pushing block 44, the second pushing block 44 pushes the first driven block 38 and the connecting block 40 to move upward, so that the first driven block 38 is in transmission cooperation with the upper screw rod 36 again, so that the second movable plate 37 drives the grinding block 7 to move towards the left side again.

[0040] Due to the fixed connections of the first pushing block 43 and the second pushing block 44 with the first movable plates 37 located on both sides respectively, the horizontal distance of the reciprocating movement of the second movable plate 37 changes with the change of the interval between the symmetric first movable plates 37, that is, the reciprocating horizontal movement distance of the second movable plate 37 will change with the change of the length of the quartz product, and it will automatically adapt to the length change of the quartz product. That is, when grinding a quartz product with a longer length, the reciprocating movement distance of the second movable plate 37 will increase. When grinding a quartz product with a shorter length, the reciprocating movement distance of the second movable plate 37 will also decrease accordingly. Thus, when grinding quartz products with different lengths, the reciprocating movement distance of the second movable plate 37 will also change with the length change of different quartz products, thereby avoiding that during the grinding process of a quartz product with a shorter length, due to the fixed stroke of the reciprocating movement of the grinding block 7, when the grinding block 7 grinds a quartz product with a shorter length, during the continuous reciprocating movement of the grinding block 7, it only contacts the quartz product for a shorter time, resulting in a low grinding efficiency of the grinding block 7 for the quartz product with a shorter length. By changing the reciprocating movement stroke of the grinding block 7 corresponding to different lengths of quartz products, the grinding block 7 can perform more grinding treatments on the quartz product within a limited time, thereby improving the grinding effect on the quartz product.

[0041] Please refer to Figure 7 As shown in the figure, a rotating column 12 is fixedly connected to the middle part of the lower end of the placing table 11. The outer wall of the lower end of the rotating column 12 is rotationally connected to the middle part of the inner cavity of the base 1. An installation plate 26 and a driving plate 27 are sleeved on the outer wall of the rotating column 12. The driving plate 27 is located below the installation plate 26. The driving plate 27 is vertically slidably connected to the bottom of the inner cavity of the base 1. The lower end of the driving plate 27 is drivingly connected with an electric push rod (not shown in the figure). Thus, the driving plate 27 is pushed to move vertically upward by the electric push rod. Symmetric adjusting rods 24 are fixedly connected to the outer wall of the installation plate 26. Symmetric second grooves 25 are opened on the inner cavity side wall of the cavity 21. The second grooves 25 are vertically slidably connected to the ends of the adjusting rods 24 far away from the installation plate 26. The upper end surface of the adjusting rod 24 and the top of the inner cavity of the second groove 25 are elastically connected by a spring. The spring will apply an upward force to the adjusting rod 24. That is, when the electric push rod pushes the driving plate 27 to move upward, the driving plate 27 will drive the traction rod 28 to move upward synchronously. At this time, the lower end of the fixed rod 29 moves relatively towards the bottom of the inner cavity of the traction rod 28, so that the bottom of the inner cavity of the traction rod 28 is separated from the outer wall of the lower end of the fixed rod 29. At this time, under the action of the elastic force, it will drive the adjusting rod 24 to move upward. When the upper end of the installation plate 26 contacts the lower end surface of the turntable 2, the adjusting rod 24 stops moving upward at this time. Then when the driving plate 27 continues to move upward, at this time, the fixed rod 29 continues to move relatively towards the bottom of the inner cavity of the traction rod 28.

[0042] Please refer toFigure 8 , a movable groove 19 is formed in the middle of the side wall of the fixed plate 17, and a clamping groove 18 is formed in the middle of the side wall of the driven plate 16. During the upward movement of the adjusting rod 24, the outer wall of the adjusting rod 24 slides in the inner cavity of the movable groove 19, but drives the driven plate 16 to move upward through cooperation with the clamping groove 18, so that the lower end surface of the driven plate 16 is higher than the upper end surface of the driven rod 23. At this time, the limit of the driven plate 16 on the driven rod 23 can be released. Symmetric vertical grooves 32 are formed in the lower outer wall of the rotating column 12. Symmetric driving rods 30 are fixedly connected to the side wall of the inner cavity of the driving plate 27. A guiding groove 31 that is centrosymmetric about the center position of the center of the rotating column 12 is formed between the symmetric vertical grooves 32. The lower end of the guiding groove 31 is connected to the middle of one of the vertical grooves 32, and the upper end of the guiding groove 31 is connected to the top of the other vertical groove 32. An installation groove 34 is formed at the connection between the lower end and the middle of the vertical groove 32. A guiding plate 33 is rotatably connected to the inner cavity of the installation groove 34. The lower end of the guiding plate 33 is elastically connected to the side wall of the inner cavity of the installation groove 34 through a spring. During the upward movement of the driving plate 27 pushed by the electric push rod, the driving rod 30 moves in the inner cavity of the vertical groove 32 towards the position where the guiding plate 33 is located. Before the vertical groove 32 contacts the guiding plate 33, the adjusting rod 24 will drive the driven plate 16 to move upward synchronously under the action of elastic force. When the lower end surface of the driven plate 16 is higher than the upper end surface of the driven rod 23, at this time, under the guiding action of the guiding plate 33, the driving rod 30 will enter the guiding groove 31 and move to the connection between the upper end of the guiding groove 31 and the vertical groove 32, thereby driving the rotating column 12 to rotate 180°, thereby driving the turntable 2 to rotate 180° through the rotation of the rotating column 12, thereby driving the quartz product to rotate 180°, thereby grinding the other side of the quartz product. During the rotation of the turntable 2 driving the clamping plate 10 and the connecting rod 15, the fixed plate 17 will first separate from one of the driven rods 23 and then contact the other driven rod 23 again. After the fixed plate 17 stops rotating, the driven rod 23 automatically fits against the outer wall of the fixed plate 17 under the action of elastic force. When the driving plate 27 moves downward, at this time, the driving rod 30 moves from the top of the inner cavity of the vertical groove 32 to the bottom of the inner cavity of the vertical groove 32. During the downward movement of the driving rod 30, the driving rod 30 will contact the upper end surface of the guiding plate 33 and thus push the guiding plate 33 to rotate towards the position where the guiding groove 31 is located, without affecting the downward movement of the driving rod 30.

[0043] A grinding method for quartz product processing includes the following steps:

[0044] S1. Place the quartz product on the placing table 11, clamp and fix the quartz product through the symmetric clamping plates 10, then drive the grinding block 7 to contact the outer wall of the quartz product through the electric telescopic push rod 5, and drive the grinding block 7 to rotate through the driving motor 8, thereby grinding the quartz product;
