[0030] See also Figure 7 and Figure 8 The blank clamping mechanism 3 includes a supporting slide bar 37, which is fixedly mounted on one end of the top of the grinding support base 1 close to the first servo motor 6. Two lifting slots 38 are symmetrically arranged on the top of the supporting slide bar 37.

The dial shell blank 47 is in contact and connected with the side of the grinding sand disc 17 away from the rotating shaft 16.

[0032] The blank clamping plate 45 is fixedly connected to a connecting bracket 50 on one side close to the lifting bracket 39, and the blank clamping plate 45 is fixedly installed on the lifting bracket 39 through the connecting bracket 50. A sliding block 51 is fixedly connected to the side of the upper clamping plate 46 close to the blank clamping plate 45.

The inclination angle of the inclined cone surface of the conical locking head 54 is the same as the inclination angle of the inner side of the conical locking groove 52. When the second locking bolt 53 drives the conical locking head 54 to rotate close to the blank clamping plate 45, the conical locking head 54 squeezes the inner bottom end of the conical locking groove 52 and moves downward, thereby driving the upper clamping plate 46 to move downward to squeeze the dial shell blank 47, and tighten the dial shell blank 47.

[0033] Working principle: During use, the dial shell blank 47 is first fixed on the blank clamping plate 45, and the dial shell blank 47 is placed on the top of the lower clamping plate 48 by external force, and then the upper clamping plate 46 is inserted into the inner side of the limiting slide groove 49 through the sliding block 51, and the upper clamping plate 46 is moved downward until the bottom end of the upper clamping plate 46 contacts the top of the dial shell blank 47, and then the second locking bolt 53 is screwed close to the blank clamping plate 45 by external force, and at the same time, the dial shell blank 47 is pressed so that the side of the dial shell blank 47 close to the blank clamping plate 45 is close to the blank clamping plate 45, and the movement of the second locking bolt 53 drives the conical locking head 54 to move, and the conical locking head 54 is inserted into the inner side of the conical locking groove 52 and squeezes the bottom end of the conical locking groove 52, and the upper clamping plate 46 is squeezed and slid downward by the conical locking head 54, so that the upper The bottom end of the clamping plate 46 is tightly against the top end of the dial shell blank 47. At this time, the dial shell blank 47 is fixed, and then the sliding base 10 is pushed by external force to slide on the slide rail 7 close to the positioning baffle 8 until one end of the sliding base 10 close to the positioning baffle 8 is tightly against the positioning baffle 8. At this time, the lock tongue 30 is inserted into the interior of the locking slot 9, and then the knob 32 is turned by external force to drive the first locking bolt 33 to rotate, so that the first locking bolt 33 is threadedly connected to the top end of the limit frame 29 and moves downward. The movement of the first locking bolt 33 pushes the support rod 34 to move downward, and the support rod 34 squeezes the lock tongue 30 to move downward. The chamfered edge at the bottom end of the lock tongue 30 is squeezed by the inner side end of the locking slot 9 to move toward the sliding base 10, thereby driving the limit frame 29 and the sliding base 10 to move close to the positioning baffle 8. At this time, the sliding base 10 is locked;

[0034] Then start grinding, start the first servo motor 6 and the second servo motor 15, and rotate the rocker 28 by external force to drive the rotating wheel 27 to rotate for advancement. The rotation of the rotating wheel 27 drives the first transmission gear 25 to rotate. Since the first transmission gear 25 is meshed and connected with the first reduction gear 23, the second transmission gear 24 is meshed and connected with the second reduction gear 26, and the second reduction gear 26 is meshed and connected with the gear rod 20, the rotation of the first transmission gear 25 drives the second reduction gear 26 to rotate through the first reduction gear 23 and the second transmission gear 24. The rotation of the second reduction gear 26 drives the gear rod 20 to rotate. The rotation of the gear rod 20 drives the threaded rod 19 to rotate. Since the threaded rod 19 is threadedly connected to the guide bracket 18, the rotation of the threaded rod 19 causes the threaded rod 19 to move in the direction of the sliding bracket 13. The threaded rod The movement of 19 pushes the sliding bracket 13 to move, and the sliding bracket 13 drives the grinding sand disc 17 to move close to the dial shell blank 47. The driving end of the second servo motor 15 drives the rotating shaft 16 and the grinding sand disc 17 to rotate. When the end of the grinding sand disc 17 away from the rotating shaft 16 contacts the dial shell blank 47, the dial shell blank 47 is polished. The driving end of the first servo motor 6 drives the push-pull turntable 43 to rotate. The rotation of the push-pull turntable 43 drives the push-pull shaft 44 to rotate. The rotation of the push-pull shaft 44 pulls the bottom end of the push-pull rod 42 to rotate, thereby driving the top end of the push-pull rod 42 to move up and down. The up and down movement of the top end of the push-pull rod 42 drives the lifting rod 41 to move up and down. The lifting rod 41 drives the lifting bracket 39 to move, thereby driving the blank clamping plate 45 and the dial shell blank 47 to move up and down, so that the dial shell blank 47 moves up and down for polishing;

[0035] While grinding, the rocker 28 is turned, and the scale line on the scale 14 is checked through the side of the guide bracket 18 close to the size adjustment component 4 to confirm the distance the sliding bracket 13 has been advanced. When the zero scale line of the scale 14 coincides with the side of the guide bracket 18 close to the size adjustment component 4, the grinding sandpaper 17 contacts the side of the blank clamping plate 45 close to the dial shell blank 47. Therefore, the thickness of the dial shell blank 47 can be confirmed according to the scale line on the scale 14, and the required thickness of the dial shell blank 47 can be ground according to the requirements. At the end of the grinding, the knob 32 is turned by external force to drive the first locking bolt 33 to rotate and move upward so that the first locking bolt 33 is separated from the top inner side of the limit frame 29. The movement of the knob 32 drives the locking tongue 30 to move upward and squeeze the energy storage spring 35 to contract, and then pushes the sliding base 10 to move away from the supporting slide rod 37. The sliding base 10 The movement of the lock tongue 30 drives the lock tongue 30 to move, and the chamfered edge at the bottom end of the lock tongue 30 is squeezed by the locking slot 9 and moves upward to the top of the slide rail 7, and then the first servo motor 6 and the second servo motor 15 are turned off, and the rocker 28 is turned to retreat. The rotation of the rocker 28 drives the rotating wheel 27 and the first transmission gear 25 to rotate, and the first transmission gear 25 drives the second reduction gear 26 to rotate through the first reduction gear 23 and the second transmission gear 24, and the second reduction gear 26 drives the gear rod 20 to rotate. The rotation of the gear rod 20 drives the threaded rod 19 to rotate and move in the direction of the guide bracket 18. The movement of the threaded rod 19 drives the sliding bracket 13 to move, and then the second locking bolt 53 is twisted away from the blank clamping plate 45 by external force, so that the conical locking head 54 is separated from the inner side of the conical locking groove 52. At this time, the upper clamping plate 46 is loosened, and the dial shell blank 47 can be removed and replaced with another dial shell blank 47 for grinding.
