[0033] Example 1 A computer-controlled panel saw includes a frame 1 and a main saw 2. Two first longitudinal slide bars 3 are arranged adjacent to each other on the frame 1, with the first longitudinal slide bars 3 positioned along the height direction of the frame 1. The side of the main saw 2 is slidably connected to the first longitudinal slide bars 3. A longitudinal rack 11 and a first cylinder 12 are respectively installed on the outer side of the bottom of the frame 1. The longitudinal rack 11 is positioned along the height direction of the frame 1. The cylinder body of the first cylinder 12 is fixedly installed on the outer side of the frame 1, and the piston rod of the first cylinder 12 is positioned along the height direction of the frame 1. A first motor 21, which is a servo motor, is installed on one side of the main saw 2. The housing of the first motor 21 is fixedly connected to the outside of the main saw 2. The motor shaft of the first motor 21 is connected to a gear 22, which meshes with the longitudinal rack 11.

Through the transmission between the gear 22 and the longitudinal rack 11, the main saw 2 can be accurately raised and lowered, achieving the grooving effect. The first cylinder 12 is used to counterweight the main saw 2. When the main saw 2 is raised and lowered, the first cylinder 12 is activated to support the main saw 2, which can effectively reduce the pressure on the first motor 21.

[0034] In this embodiment, a first reducer 23 is installed on one side of the main saw 2. The housing of the first reducer 23 is fixedly connected to one side of the main saw 2. One end of the first motor 21 is connected to one side of the first reducer 23. The input end of the first reducer 23 is connected to the output shaft of the first motor 21 to convert the rotational motion of the first motor 21 into a speed-reducing and torque-increasing motion. The output end of the first reducer 23 is connected to the gear 22 to drive the gear 22 to output torque, so that the gear 22 and rack can better cooperate in transmission, thereby realizing the lifting and lowering of the main saw 2.

[0035] In this embodiment, a mounting base 24 is fixedly installed on one side of the main saw 2, and the housing of the first reducer 23 is fixedly installed on the mounting base 24. By providing the mounting base 24, it is convenient to install and fix the first reducer 23.

[0036] In this embodiment, a base 13 is fixedly installed on one side of the frame 1, and the cylinder body of the first cylinder 12 is fixedly installed on the base 13. By setting the base 13, the bottom of the cylinder body of the first cylinder 12 can be placed on the base 13, which facilitates the fixing of the cylinder body of the first cylinder 12.

[0037] In this embodiment, the computer panel saw also includes a grooving saw 4. Two second longitudinal slide rods 14 are arranged adjacent to each other on the frame 1. The second longitudinal slide rods 14 are arranged along the height direction of the frame 1. The side of the grooving saw 4 is slidably connected to the second longitudinal slide rods 14. A second cylinder 15 is installed on the other side of the bottom of the frame 1. The cylinder body of the second cylinder 15 is fixedly connected to the frame 1. The piston rod end of the second cylinder 15 is fixedly connected to one side of the bottom of the grooving saw 4. The second cylinder 15 is used to push the grooving saw 4 so that the grooving saw 4 can be raised.

[0038] Example 2 The difference between this embodiment and embodiment 1 is that a limit assembly 5 is provided above the second cylinder 15. The limit assembly 5 includes a positioning seat 51, an adjusting seat 52, a fork 53, an adjusting screw 54, and a second motor 55. The second motor 55 is a servo motor. The positioning seat 51 and the adjusting seat 52 are both fixedly mounted on the frame 1. The side of the fork 53 is rotatably connected to the positioning seat 51. One end of the fork 53 is connected to one side of the slot saw 4. The adjusting seat 52 has an adjusting groove 521 and a threaded hole 522 that are interconnected inside. The other end of the fork 53 extends into the adjusting groove 521. The frame 1 is provided with an adjusting hole (not shown in the figure) for the fork 53 to pass through. The positioning seat 51 and the adjusting seat 52 are arranged opposite each other on both sides of the adjusting hole. The adjusting screw 54 is screwed into the threaded hole 522. The second motor 55 is mounted on the outside of the adjusting seat 52. One end of the adjusting screw 54 is connected to the second motor 55 for transmission. The other end of the adjusting screw 54 abuts against the end of the fork 53 that extends into the adjusting groove 521. The second motor 55 drives the adjusting screw 54 to rotate. The adjusting screw 54 can push one end of the fork 53 into the adjusting groove 521 to move, causing the end of the fork 53 connected to one side of the grooving saw 4 to move, thereby driving the grooving saw 4 to descend. Through the cooperation of the second cylinder 15 and the limiting component 5, the height of the grooving saw 4 can be adjusted.

[0039] In this embodiment, the limiting component 5 also includes a second reducer 56. One end of the second reducer 56 is connected to the outside of the adjusting seat 52, and the other end of the second reducer 56 is connected to the second motor 55. The input end of the second reducer 56 is connected to the output shaft of the second motor 55, and the output end of the second reducer 56 is connected to one end of the adjusting screw 54.

[0040] In this embodiment, the side of the positioning seat 51 has a limiting groove 511, the side of the shift fork 53 extends into the limiting groove 511, a pin 512 is provided on the positioning seat 51, one end of the pin 512 passes through the side of the shift fork 53, a spring 513 is connected to the top of the positioning seat 51, the top of the positioning seat 51 has a mounting hole, one end of the spring 513 extends into the mounting hole, and the other end of the spring 513 abuts against the outer side of the end of the shift fork 53 near the adjusting seat 52. The spring 513 can push the shift fork 53 towards the adjusting screw 54 when the adjusting screw 54 rotates back to the threaded hole 522, so that one end of the adjusting screw 54 always abuts against the side of the shift fork 53, thereby allowing the shift fork 53 to be reset.

[0041] In this embodiment, the slot saw 4 includes a slide plate 41, a saw base 42, a saw body 43, a saw shaft 44, an adjusting worm gear 45, and a third motor 46.

The third motor 46 is mounted on one side of the saw base 42 and is drivenly connected to one end of the adjusting worm gear 45. The third motor 46 drives the adjusting worm 45 to rotate. The transmission between the adjusting worm 45 and the worm wheel 441 allows the saw shaft 44 to rotate. The engagement of the external thread 442 and the internal thread 4211 allows the saw shaft 44 to move along its axial direction, thereby realizing the back-and-forth movement of the saw body 43. The saw body 43 has multiple annular grooves on its exterior to increase friction. A transmission belt is installed on the outer side of the annular grooves. The saw body 43 is connected to the motor via the transmission belt. The motor drives the saw body 43 to rotate along the saw shaft 44 via the transmission belt, which is a conventional driving method. No specific limitation is made here, and it can be selected according to the specific situation.

[0042] In this embodiment, the slot saw 4 also includes a third reducer 47 and a coupling 48. One end of the third reducer 47 is connected to one end of the third motor 46, and the other end of the third reducer 47 is connected to one side of the saw base 42.
