DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-Figure 6 A high-precision metal sheet slotting machine comprises a machine table 1 and a slotting machine head body 4, a sliding seat 2 is slidably connected to the machine table 1, a slider 16 is slidably connected in the sliding seat 2, a hydraulic cylinder 6 is fixedly installed on the lower surface of the slider 16, a bracket 5 is fixedly connected to the driving end of the hydraulic cylinder 6, the slotting machine head body 4 is fixedly installed on the lower surface of the bracket 5, a plurality of rotating components are arranged on the bracket 5, each rotating component comprises a rotating shaft 22 connected to the bracket 5 through a torsion spring 23, one end of the rotating shaft 22 is fixedly connected to an air suction cylinder 7, a filter box 19 is fixedly connected to one side of the slider 16, a plurality of filter holes 29 are provided on both side surfaces of the filter box 19, an air suction pump 25 is fixedly installed on the filter box 19, a fixed pipe 24 is fixedly installed on the air suction pump 25, and each air suction cylinder 7 is connected to the fixed pipe 24 through a hose 20;

[0029] The bracket 5 is provided with a sliding assembly, which includes a moving block 13 slidably mounted on the bracket 5. The moving block 13 is connected to each rotating shaft 22 through a plurality of pull ropes 12. The bracket 5 is provided with a rotating assembly, which includes a first motor fixedly mounted on one side of the bracket 5. The driving end of the first motor is fixedly connected to a fixed shaft 8, and a cam 9 is fixedly connected to the fixed shaft 8. When the first motor drives the fixed shaft 8 to rotate, the cam 9 is driven to rotate together. During the rotation of the cam 9, one end of the cam 9 will squeeze and detach from the moving block 13 for many times. The moving block 13 will slide relative to the bracket 5 and will not detach from the bracket 5. The friction between the moving block 13 and the bracket 5 is relatively large, which can prevent the moving block 13 from moving up and down at will.

[0030] The cross section of the moving block 13 is T-shaped, and a limiting rod 21 is fixedly connected to the bracket 5. The upper end surface of the limiting rod 21 fits with the surface of the moving block 13. When the cam 9 and the moving block 13 are disengaged, the moving block 13 will move down to the initial position under the action of gravity, that is, the surface of the moving block 13 fits with the upper end surface of the limiting rod 21 again. The limiting rod 21 has a limiting effect on the moving block 13. A sealing cover 14 is sleeved on the outer side of the filter box 19. A sealing ring is fixedly connected to the inner wall of the sealing cover 14. The sealing ring is arranged between the inner wall of the sealing cover 14 and the outer surface of the filter box 19. The sealing ring can improve the sealing performance when the sealing cover 14 is connected to the filter box 19, and prevent impurities from overflowing from the connecting gap between the filter box 19 and the sealing cover 14.

[0031] A scraper 26 is slidably installed in the filter box 19, and a bending block 27 is fixedly connected to the scraper 26. The surface of the bending block 27 fits the surface of the filter box 19. In the initial state, the back of the scraper 26 is in close contact with the inner wall of the filter box 19, so that the sealing cover 14 and the filter box 19 are separated. Then, the bending block 27 is pulled outward, and the scraper 26 will move outward along the inner walls of the sides of the filter box 19 until it is separated from the filter box 19. The movement of the scraper 26 can push out all the impurities accumulated inside the filter box 19, making it easier to clean the debris and impurities.

[0032] An ear plate 15 is fixedly connected to the surface of one side of the sealing cover 14, and the ear plate 15 is connected to the filter box 19 through an insertion rod 28. A threaded groove for connecting the insertion rod 28 is provided on the filter box 19. The cross-section of the insertion rod 28 is T-shaped. One end of the insertion rod 28 is passed through the ear plate 15 and the bending block 27 in sequence and is threadedly connected to the threaded groove. The insertion rod 28 is also threadedly connected to the ear plate 15 at this time, and the end face of the T-shaped insertion rod 28 with a larger area fits with the surface of the bending block 27, which can prevent the sealing cover 14 from detaching from the filter box 19.

[0033] A second motor and a first fixed rod 18 are fixedly installed on the sliding seat 2, and the driving end of the second motor is fixedly connected to the first reciprocating screw rod 17. The slider 16 is threadedly connected to the first reciprocating screw rod 17, and the slider 16 is provided with a through hole for connecting the first fixed rod 18. A third motor is fixedly installed on the machine table 1. The machine table 1 is provided with two grooves, in which the second reciprocating screw rod 11 is rotatably installed in one of the grooves, and the second fixed rod 10 is fixedly connected in the other groove. The sliding seat 2 and the second reciprocating screw rod 11 are threadedly connected, and the sliding seat 2 and the second fixed rod 10 are slidably connected. The driving end of the third motor is fixedly connected to the second reciprocating screw rod 11. A placement groove is provided on the machine table 1, and electric push rods are fixedly installed on the inner walls of both sides of the placement groove, and the driving end of each electric push rod is fixedly connected to a clamping plate 3.

[0034] The metal sheet to be processed is placed in the placement groove, and then the two electric push rods push the two clamps 3 to move, and the distance between the two clamps 3 is reduced until the surfaces of the two clamps 3 are respectively in close contact with the two side surfaces of the metal sheet, and the metal sheet can be clamped. The second motor drives the first reciprocating screw 17 to rotate. Under the transmission action of the first reciprocating screw 17, the slider 16 will move along the first reciprocating screw 17 and slide relative to the first fixed rod 18, thereby driving the groove planing head body 4 on the bracket 5 to move together. During the process of the third motor driving the second reciprocating screw 11 to rotate, the sliding seat 2 and the groove planing head body 4 on the bracket 5 can move along the second reciprocating screw 11 and slide relative to the second fixed rod 10.

[0035] In the present invention, when in use, the metal sheet to be processed is placed in the placement groove and clamped, and then the second motor drives the first reciprocating screw 17 to rotate. Under the transmission action of the first reciprocating screw 17, the slider 16 will move along the first reciprocating screw 17, thereby driving the groove planing head body 4 on the bracket 5 to move together. During the process of the third motor driving the second reciprocating screw 11 to rotate, the sliding seat 2 and the groove planing head body 4 on the bracket 5 can move along the second reciprocating screw 11, the hydraulic cylinder 6 drives the bracket 5 to move downward, and the groove planing head body 4 moves downward at the same time. During the translation of the groove planing head body 4, the metal sheet can be grooved.

[0036] During the process of the slotting machine head body 4 slotting the metal sheet, the suction cylinders 7 on the bracket 5 will move synchronously, and the suction pump 25 and the first motor will operate at the same time. Since one end of each hose 20 is fixedly connected to the fixed pipe 24, and the other end is fixedly connected to the corresponding suction cylinder 7, the suction cylinder 7 can be used to draw the debris generated during the slotting process and the air in the environment into the filter box 19 through the hose 20 and the fixed pipe 24. The impurities and debris are blocked by the filter hole 29 and stay in the filter box 19. The air that has filtered out the impurities can pass through the filter hole 29 and be discharged. After the processing is completed, the staff does not need to clean the table surface. The operation is relatively simple and quick, and it can effectively prevent debris from floating in the air to avoid inhalation by the staff, which is beneficial to the use of the slotting machine. In the process of the first motor driving the fixed shaft 8 to rotate, the cam 9 will be driven to rotate together. During the rotation of the cam 9, one end of the cam 9 will squeeze and disengage from the moving block 13 many times. When the cam 9 squeezes the moving block 13, the moving block 13 will move upward and will not be separated from the bracket 5. Under the transmission action of the moving block 13, one end of multiple inelastic pull ropes 12 moves up at the same time.

[0037] Since one end of each pull rope 12 is fixedly connected to the moving block 13, and the other end is respectively wound around the corresponding rotating shaft 22, under the transmission action of the pull rope 12, the rotating shaft 22 will rotate relative to the bracket 5, thereby driving the suction cylinder 7 to deflect at a small angle. When the cam 9 and the moving block 13 are separated, the moving block 13 will move down to the initial position under the action of gravity, that is, the surface of the moving block 13 will fit the upper end surface of the limit rod 21 again. Since one end of each torsion spring 23 is respectively connected to the corresponding The corresponding rotating shaft 22 is fixedly connected, and the other end is fixedly connected to the bracket 5. During the downward movement of the moving block 13, under the elastic force of the torsion spring 23, the rotating shaft 22 and the suction cylinder 7 will rotate to the initial angle, that is, the suction cylinder 7 is in a vertical state. During the swinging back and forth of each suction cylinder 7, the debris mixed in the surrounding air and the debris on the metal sheet can be extracted, so that the suction cylinder 7 can better and more thoroughly extract impurities and debris, so that the collection and cleaning effect of impurities and debris is better.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
