Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a laser cutting auxiliary device. Background Art

[0002] Laser cutting machines are widely used in the steel cutting industry. They use laser beams to perform various processes, such as cutting, engraving, and drilling. While existing CNC laser cutting machines are capable of performing complex cutting operations on workpieces, some manufacturers still rely on traditional linear motion laser cutting machines due to cost constraints. Consequently, using traditional laser cutting machines to process certain special-shaped structural parts with specialized processing requirements presents a challenge. For example, one of our special-shaped steel plates initially consists of a base plate and side panels at either end, forming a 160° angle with the base plate. During subsequent processing, the side panels must be laser cut along their length, and a portion of the side panels must be flanging after cutting. Traditional processing methods require multiple positioning and cutting steps, and the flanging process requires separate equipment. To save costs and improve processing efficiency, it is necessary to improve existing laser cutting machines to address these challenges. Summary of the Invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] See also Figures 1 to 9 , the present invention provides a technical solution:

[0035] A laser cutting auxiliary device includes a tooling table 1, a support base 2, a rotatable support table 3 and a guide block 7;

[0036] The tooling table 1 is installed on the bed of the machine tool and is used to support the support base 2. The tooling table 1 plays the role of supporting the entire upper support platform 3 and other related components. Its installation position on the bed can be adjusted as needed.

[0037] In an embodiment of the present invention, the bottom of the support platform 3 is rotatably mounted on the support base 2 by means of a support shaft 33. The upper part of the support platform 3 has a placement portion 30 for placing the workpiece to be cut (i.e., a special-shaped steel plate including a base plate 300 and a side plate 400). The shape of the placement portion 30 matches the shape of the workpiece to be cut; the bottom of both ends of the support platform 3 is connected to the support base 2 by means of a retractable reset mechanism 4 so that the support platform 3 can maintain a horizontal state.

[0038] Furthermore, the reset mechanism 4 in the embodiment of the present invention includes a piston cylinder 40, a piston rod 41, and a reset spring 43. One end of the piston rod 41 is slidably connected to the piston cylinder 40 by means of a piston 42 and is restrained in the piston cylinder 40 by means of a cylinder cover 44. The reset spring 43 is sleeved on the piston rod 41 between the piston 42 and the cylinder cover 44. The other end of the piston rod 41 is hinged to a support 45 at the bottom of the support platform 3, and the lower end of the piston cylinder 40 is hinged to a support 45 at the top of the workbench 1. The reset mechanism 4 has two groups and is symmetrically arranged below the support platform 3. With the action of the reset spring 43, the support platform 3 can maintain a horizontal state in the initial state. The horizontal state of the support platform 3 is only released when the guide block 7 contacts the guide rod 54.

[0039] In an embodiment of the present invention, in order to achieve the cutting of the side panel 400, a lifting mechanism 5 for adjusting the angle of the support platform 3 is also installed on the support base 2. The lifting mechanism 5 has two groups and is symmetrically arranged. The upper end of the lifting mechanism 5 is connected to the support platform 3. With the help of the lifting mechanism 5, the posture of the side panel 400 can be adjusted so that it is in a horizontal state during cutting. Specifically, the lifting mechanism 5 includes a column 50, a lifting rod 51 and a lifting slider 52. The lower end of the column 50 is installed on the workbench 1, and the upper end of the column 50 is installed with a nut for limiting, which is used to limit the lifting slider 52. The lifting slider 52 is slidably connected to the column 50 and a guide rod 54 is installed on the inner side of the lifting slider 52. The lower end of the lifting rod 51 is rotatably connected to the guide rod 54, and the upper end of the lifting rod 51 is rotatably connected to the support platform 3. Specifically, a transverse shaft 53 is provided on the inner side of the support platform 3 , and the upper end of the lifting rod 51 is rotatably connected to the transverse shaft 53 and is limited by a nut.

[0040] Under the action of the guide block 7, the guide rod 54 will be lifted to a certain height. Since the lifting rod 51 is connected to the support platform 3, it will lift one end of the support platform 3 to a certain height and make the side plate 400 of the workpiece to be cut at this end in a horizontal state. Then the laser cutting gun 100 passes here and cuts it; similarly, when the guide block 7 contacts the other guide rod 54, it will lift the other end of the support platform 3, and then cut the other side plate 400.

[0041] In an embodiment of the present invention, notches 34 are provided on both sides of the placement portion 30, and a flip-up flanging block 32 is provided in the notch 34. The inner side of the support platform 3 is also equipped with a driving component 6 that cooperates with the flanging block 32 to realize the flanging of the workpiece to be cut; one end of the flanging block 32 is rotatably connected to the bearing provided in the side wall of the notch 34 by means of a connecting shaft 1 320, and the other end of the flanging block 32 is connected to the driving component 6 by means of a connecting shaft 2 321; the driving component 6 can cooperate with the guide block 7 to achieve the above-mentioned purpose.

[0042] Specifically, the driving assembly 6 includes a top plate 60, a lifting slider 61, a connecting rod 62 and an adjusting rod 63;

[0043] The top plate 60 is fixed to the inner side of the support platform 3 and close to the placement part 30. The lower end of the top plate 60 is fixed with a lifting rod 600. The lifting slider 61 is slidably connected to the lifting rod 600 and limited by a nut. One side of the lifting slider 61 is in contact with the inner side of the support platform 3, and can provide stable support with the help of the support platform 3. A return spring 2 64 is sleeved on the lifting rod 600 between the lifting slider 61 and the top plate 60. A guide rod 2 65 is installed on the inner side of the lifting slider 61. The guide rod 2 65 is rotatably connected to two symmetrically arranged connecting rods 62. Two symmetrically arranged slide rails 66 are also installed on the inner side of the support platform 3. Each slide rail 66 is slidably connected to a linkage slider 67. The inner side of the linkage slider 67 is fixed with a connecting shaft 3 68. The other end of the connecting rod 62 and one end of the adjusting rod 63 are rotatably connected to the connecting shaft 3 68, and the other end of the adjusting rod 63 is rotatably connected to the connecting shaft 2 321.

[0044] When the guide block 7 contacts the second guide rod 65, the second guide rod 65 and the lifting slider 61 are lifted to a certain height. Then, with the help of the connecting rod 62 and the adjusting rod 63, the flanging block 32 is lifted and flipped to a certain angle, completing the flanging process of the cut side panel 400. When the guide block 7 is out of contact with the second guide rod 65, the flanging block 32 is reset.

[0045] In order to achieve the purpose of the present invention, the guide block 7 is also provided. The guide block 7 is installed at the lower part of the vertical slide 200 in the laser cutting assembly and can cooperate with the lifting mechanism 5 and the driving assembly 6 to realize the adjustment of the angle of the support table 3 and the flanging processing of the workpiece to be cut.

[0046] In an embodiment of the present invention, considering the installation of the workpiece to be cut, a limit plate 31 for limiting the workpiece to be cut is provided above the placement portion 30, and an assembly plate perpendicular to the limit plate 31 is connected to the inner side of the limit plate 31. The limit plate 31 is installed and fixed to the support table 3 with the aid of the assembly plate, and one side of the limit plate 31 is close to the flanging block 32.

[0047] The working process and principle of the present invention are further described below:

[0048] First, the staff inserts the workpiece to be cut (i.e., the base plate 300 and the side plate 400) from the side into the placement part 30 between the limit plate 31 and the support platform 3, and then starts the horizontal drive component 6 in the machine tool and drives the laser cutting gun 100 and the guide block 7 with the adjusted height to move toward the workbench 1.

[0049] The guide block 7 first contacts one of the guide rods 1 54 and, under the action of the guide block 7, the guide rod 1 54 is lifted to a certain height. Since the lifting rod 51 is connected to the support platform 3, it lifts one end of the support platform 3 to a certain height and makes the side panel 400 of the workpiece to be cut at this end in a horizontal state. Then, the laser cutting gun 100 passes through this position and cuts it. When the guide block 7 is out of contact with the guide rod 1 54, the support platform 3 returns to a horizontal state under the action of the reset mechanism 4. Then, when the guide block 7 contacts the other guide rod 1 54, the other end of the support platform 3 is lifted in the same way, and then the other side panel 400 is cut. In this way, the cutting of the side panel 400 is completed.

[0050] The laser cutting gun 100 is then raised to a certain height and its power switch is turned off. Under the action of the horizontal drive assembly 6, the laser cutting gun 100 and the guide block 7 move in the opposite direction toward the workbench 1. When the guide block 7 contacts the second guide rod 65, it raises the second guide rod 65 and the lifting slide 61 to a certain height. Subsequently, with the help of the connecting rod 62 and the adjustment rod 63, the flanging block 32 is lifted and tilted to a certain angle, completing the flanging of the cut side panel 400. When the guide block 7 disengages from the second guide rod 65, the flanging block 32 returns to its original position.

[0051] Through the above steps, the laser cutting gun 100 can complete the cutting and flanging of the two side panels 400 of the cutting tool in one back-and-forth movement, thereby significantly improving the processing efficiency.

[0052] Based on the above, the present invention utilizes a lifting mechanism 5 to achieve angle adjustment of the support platform 3 on a conventional linearly movable laser cutting machine platform, thereby facilitating the cutting of the two side panels 400 with the cooperation of the laser cutting gun 100, eliminating multiple positioning and corresponding cutting operations, and improving processing efficiency. The present invention also utilizes a drive assembly 6 and a flanging block 32 to achieve flanging of the side panels 400 during the return of the laser cutting gun 100, eliminating repeated positioning of the flanging process offline and further improving processing efficiency.

[0053] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
