[0044] By starting the third motor 503 to drive the spline shaft 504 fixedly connected to its output end to rotate, since the outer surface of the spline shaft 504 is in spline connection with the inside of the adjusting assembly 6, when the spline shaft 504 rotates, it can drive the adjusting assembly 6 to perform a circular motion, thereby providing stable power for the adjusting assembly 6.

[0045] In one embodiment, for the above-mentioned adjusting assembly 6, the adjusting assembly 6 includes an adjusting frame 601. The top end of the adjusting frame 601 is rotatably arranged with the bottom end of the connecting seat 502. An adjusting plate 602 is slidably arranged inside the adjusting frame 601. An adjusting hole 603 is opened inside the adjusting plate 602. A limiting hole 604 is opened inside the adjusting hole 603. A limiting rod 605 is slidably arranged inside the limiting hole 604.

[0046] The bottom end of the adjusting frame 601 is fixedly connected with a limiting cylinder 606. A slider 607 is slidably arranged inside the limiting cylinder 606. The top end of the slider 607 is fixedly connected with the bottom end of a limiting rod 605. A spline groove 608 is formed at the top end of the slider 607.

A spring 609 is fixedly connected to one side of the slider 607, and a pull rod 610 is fixedly connected to one side of the slider 607.

[0047] By starting the third motor 503 to drive the spline shaft 504 fixedly connected to its output end to rotate, the spline shaft 504 can drive the slider 607 to rotate in cooperation with the spline groove 608 on its outer surface in spline connection. Since the top end of the slider 607 is fixedly connected with the limiting rod 605, and the outer surface of the limiting rod 605 is slidably arranged inside the limiting hole 604, when the slider 607 rotates, it can drive the adjusting frame 601 to perform a circular motion in cooperation with the limiting rod 605 and the limiting hole 604. By pulling the pull rod 610 to drive the slider 607 fixedly connected to one end thereof to move, when the slider 607 moves, it can drive the limiting rod 605 fixedly connected to its top end and the formed spline groove 608 to move downward, so that the limiting rod 605 and the spline groove 608 are respectively disengaged from the inside of the limiting hole 604 and the outer surface of the spline shaft 504. Then, by pulling the adjusting plate 602, it can slide inside the adjusting frame 601, and thus the extended length of the adjusting plate 602 can be adjusted. After adjusting to a suitable position, release the pull rod 610. Under the action of the spring 609, it can push the slider 607 to reset, and then drive the spline groove 608 and the limiting rod 605 to cooperate with the spline shaft 504 and the limiting hole 604 again, which is relatively convenient.

[0050] In summary, by means of the above technical solution of the present utility model, the board is placed on the top of the support plate 204, and then the electric push rod 302 is started to drive the rotating seat 303 fixedly connected to its telescopic end to move downward. When the rotating seat 303 moves, it can drive the pressing plate 304 rotatably arranged at its bottom end to move, so as to squeeze and fix the top of the board. Then, the first motor 202 is started to drive the support shaft 203 fixedly connected to its output end to rotate. When the support shaft 203 rotates, it can drive the support plate 204 fixedly connected to its top end to rotate, and cooperate with the pressing plate 304 to drive the board to perform a circular motion, so that it rotates 45 degrees, making one corner of the board face one side of the fixed frame 301. Then, the pull rod 610 is pulled to drive the slider 607 fixedly connected to one end of it to move. When the slider 607 moves, it can drive the limiting rod 605 fixedly connected to its top end and the spline groove 608 opened to move downward, so that the limiting rod 605 and the spline groove 608 are respectively disengaged from the inside of the limiting hole 604 and the outer surface of the spline shaft 504. Then, by pulling the adjusting plate 602, it can slide inside the adjusting frame 601, so as to adjust the extending length of the adjusting plate 602. When adjusted to the appropriate position, the pull rod 610 is released, and under the action of the spring 609, it can push the slider 607 to reset, so as to drive the spline groove 608 and the limiting rod 605 to cooperate with the spline shaft 504 and the limiting hole 604 again, so as to adjust the radius of the adjusting plate 602. Then, the fourth motor 701 is started to drive the grinding rod 702 fixedly connected to its output end to rotate, and at the same time, the third motor 503 is started to drive the spline shaft 504 fixedly connected to its output end to rotate. The spline shaft 504 can cooperate with the spline groove 608 connected by splines on its outer surface to drive the slider 607 to rotate. Since the limiting rod 605 is fixedly connected to the top end of the slider 607, and the outer surface of the limiting rod 605 is slidably arranged inside the limiting hole 604, when the slider 607 rotates, it can cooperate with the limiting rod 605 and the limiting hole 604 to drive the adjusting frame 601 to perform a circular motion. The adjusting frame 601 can drive the adjusting plate 602 arranged inside it to rotate. When the adjusting plate 602 drives the fourth motor 701 and the grinding rod 702 to perform a circular motion, it can perform fillet processing with different diameters on the corner of the board.

[0051] Through the above technical solution: 1. By starting the rotating assembly 5 to drive the adjusting assembly 6 fixedly installed at its bottom to perform circular motion, when the adjusting assembly 6 performs circular motion, it can drive the trimming assembly 7 fixedly installed at its top to perform circular motion, making its outer surface fit one side of the plate, and keeping the center position of the rotating assembly 5 directly above a point on the plate. Then start the trimming assembly 7 to make it rotate, and then start the rotating assembly 5 again, which can drive one end of the adjusting assembly 6 to perform reverse circular motion, thereby driving the trimming assembly 7 to perform fillet machining along the corner of the plate. This is time-saving and labor-saving, and the position of the plate can be fixed in cooperation with the supporting assembly 2 and the fixing assembly 3, thereby improving its stability during the machining process and avoiding errors during the machining process;

[0052] 2. By pulling the pull rod 610 to drive the slider 607 fixedly connected to one end thereof to move, when the slider 607 moves, it can drive the limiting rod 605 fixedly connected to its top and the spline groove 608 opened to move downward, enabling the limiting rod 605 and the spline groove 608 to disengage from the inside of the limiting hole 604 and the outer surface of the spline shaft 504 respectively. Then, by pulling the adjusting plate 602, it can slide inside the adjusting frame 601, and thus the extended length of the adjusting plate 602 can be adjusted. When adjusted to the appropriate position, release the pull rod 610. Under the action of the spring 609, it can push the slider 607 to reset, thereby driving the spline groove 608 and the limiting rod 605 to cooperate with the spline shaft 504 and the limiting hole 604 again, and then the radius of the adjusting plate 602 can be adjusted. Therefore, when the adjusting plate 602 drives the fourth motor 701 and the grinding rod 702 to perform circular motion, fillet machining with different diameters can be performed at the corner of the plate.
