[0024] The second positioning mechanism 4 includes a second groove 41. The second groove 41 is opened on the left side of the top of the table 1. A second rotating shaft 42 is rotatably installed inside the second groove 41 through a bearing. A second movable block 43 is arranged on the outer side of the second rotating shaft 42. A second clamping block 44 is fixed to the top of the second movable block 43. The bottom of the second clamping block 44 is in contact with the top of the table 1. The end of the second rotating shaft 42 passes through the inside of the table 1 and is fixed with a third handle 45.

[0026] The inner wall of the slide groove 22 and the outer wall of the slide plate 24 fit together, the slide plate 24 and the slide groove 22 form a sliding structure, the side of the movable plate 23 and the inner side of the through groove 21 fit together, the table 1 and the first screw rod 25 are threadedly connected, ensuring that when the first screw rod 25 rotates, the first screw rod 25 can push the movable plate 23 to move inside the through groove 21, and can enable the slide plate 24 to move inside the slide groove 22, and the design of the slide groove 22 and the slide plate 24 enables the movable plate 23 to move stably left and right.

[0027] Opposite threads are provided at both ends of the first rotating shaft 32, the first rotating shaft 32 and the first movable block 33 are threadedly connected, two first movable blocks 33 are symmetrically distributed about the central axis of the first rotating shaft 32, the sides of the first movable block 33 are in contact with the inner side of the first groove 31, and the first clamping block 34 is designed as an "L"-shaped structure. There are two first clamping blocks 34 symmetrically distributed about the central axis of the first rotating shaft 32, ensuring that the first rotating shaft 32 rotates so that the two first movable blocks 33 can move towards each other or move away from each other, thereby driving the two first clamping blocks 34 to move towards each other or move away from each other. Since the first clamping block 34 is designed as an "L"-shaped structure, it can position the two corners on the right side of the plate.

[0028] Opposite threads are provided at both ends of the second rotating shaft 42, and the second rotating shaft 42 and the second movable block 43 are threadedly connected. The outer wall of the second movable block 43 fits with the inner wall of the second groove 41, and the second clamping block 44 is designed to be an "L"-shaped structure. There are two second clamping blocks 44 symmetrically distributed about the central axis of the second rotating shaft 42, which ensures that when the second rotating shaft 42 rotates, the two second movable blocks 43 can move towards each other or move away from each other, thereby driving the two second clamping blocks 44 to move towards each other or move away from each other. Since the second clamping block 44 is designed to be an "L"-shaped structure, it can position the two corners on the left side of the plate.

[0029] The fixed plate 51 and the second screw rod 52 are threadedly connected, and the bottom of the pressing plate 54 and the top of the movable plate 23 fit each other. By rotating the second screw rod 52, the pressing plate 54 can be driven to move up and down, so that the pressing plate 54 can fix plates of different thicknesses, avoiding the phenomenon of warping during plate processing.

[0030] Working principle: When using the high-precision plate processing four-corner locator, first place the plate on the top of the table 1, and make one corner of the plate fit with the second clamping block 44, then rotate the first handle 26, and then the first handle 26 drives the first screw rod 25 to rotate. Since the first screw rod 25 and the table 1 are threadedly connected, the first screw rod 25 pushes the movable plate 23 to move to the left, and the movable plate 23 drives the slide plate 24 to move to the left inside the slide groove 22 until one of the first clamping blocks 34 fits with a corner of the plate, and the length of the plate is positioned at this time;

[0031] Then, the third handle 45 is rotated, and the third handle 45 drives the second rotating shaft 42 to rotate. Since opposite threads are provided at both ends of the second rotating shaft 42, and the second rotating shaft 42 and the second movable block 43 are threadedly connected, and the outer wall of the second movable block 43 fits the inner wall of the second groove 41, the two second movable blocks 43 move toward each other, and the two second clamping blocks 44 move toward each other, so that the two left corners of the plate are positioned;

[0032] Then the second handle 38 is rotated, and then the second handle 38 drives the connecting shaft 37 to rotate, and then the connecting shaft 37 drives the first rotating shaft 32 to rotate through the second bevel gear 36 and the first bevel gear 35. Since opposite threads are arranged at both ends of the first rotating shaft 32, and the first rotating shaft 32 and the first movable block 33 are threadedly connected, and there are two first movable blocks 33 symmetrically distributed about the central axis of the first rotating shaft 32, and the sides of the first movable blocks 33 are fitted with the inner side of the first groove 31, the two first movable blocks 33 move towards each other, and at the same time, the two first clamping blocks 34 move towards each other, so as to position the two right corners of the plate;

[0033] In summary, the four corners of plates of different sizes can be positioned quickly and accurately, which improves the efficiency of plate processing.
