[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0027] The laser cutting and fixing device according to the embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0028] like Figure 1-Figure 3 As shown, the laser cutting processing fixing device of the embodiment of the utility model may include an installation box 1, multiple pillars 2, a driving mechanism 3, a first clamping mechanism 4, a second clamping mechanism 6, a support rod 5, a laser cutting mechanism 7, a cooling mechanism 8 and multiple partitions 9.

[0029] Among them, multiple partitions 9 are installed on the installation box 1, multiple pillars 2 are installed at the four corners of the installation box 1, the driving mechanism 3 and the support rod 5 are both installed on the pillars 2, the driving mechanism 3 is installed on one side of the installation box 1, and the support rod 5 is installed on the other side of the installation box 1.

[0030] It can be understood that the support rod 5 and the driving mechanism 3 can be supported by the provided support column 2, and at the same time, the provided partition plate 9 can collect dust and debris generated by welding.

[0031] The first clamping mechanism 4 and the second clamping mechanism 6 are both installed between the driving mechanism 3 and the support rod 5 . The first clamping mechanism 4 and the second clamping mechanism 6 are arranged to form a semi-enclosed structure. The laser cutting mechanism 7 is installed on the support rod 5 .

[0032] It should be noted that, in this embodiment, the first clamping mechanism 4 and the second clamping mechanism 6 are provided with slots, which can facilitate the insertion of the laser cutting mechanism 7. At the same time, the semi-enclosed structure can block dust generated by welding and prevent it from spraying and overflowing.

[0033] The cooling mechanism 8 is disposed inside the installation box 1 , and the cooling mechanism 8 may include an exhaust fan 81 and an exhaust port 82 .

[0034] The air outlet 82 is connected to the exhaust fan 81 , and the air outlet 82 corresponds to the position of the laser cutting mechanism 7 .

[0035] Specifically, when laser cutting of the workpiece is required, the workpiece is placed between the two cover shells. Then, the protruding length of the stud 63 inside the first cover shell 41 is adjusted and fixed by a nut, thereby fixing the baffle 64. At the same time, the push rod motor 45 pushes the connecting rod 42 and the pressure plate 43, and the workpiece is clamped by the baffle 64 and the pressure plate 43.

[0036] When the workpiece is clamped, the rotating motor 31 drives the threaded rod 32 to rotate. When the threaded rod 32 rotates, the moving block 33 moves. Since the first cover shell 41 is threadedly connected to the support rod 5 through the sliding block 44, it can drive the first cover shell 41 to move. When the two cover shells are spliced ​​together, a semi-enclosed structure is formed. The laser head 74 is adjusted by the electric slider 73 to perform laser cutting. At this time, the exhaust fan 81 is turned on. The exhaust fan 81 can suck dust and make the air inside the first cover shell 41 and the second cover shell 61 produce convection to cool down.

[0037] Therefore, by cooperating with the exhaust port 82, the first cover shell 41, the second cover shell 61 and the partition plate 9, more effective heat dissipation can be achieved during the cutting process, reducing the thermal deformation of the cut piece during the processing process, and improving the accuracy and stability of laser cutting. At the same time, the emission of dust and smoke in the air can be reduced.

[0038] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the first clamping mechanism 4 may include a first cover shell 41 , a connecting rod 42 , a pressing plate 43 , a sliding block 44 , a push rod motor 45 and a fixing block 46 .

[0039] The fixed block 46 and the sliding block 44 are respectively installed on two sides of the first cover shell 41 , the fixed block 46 is connected to the driving mechanism 3 , and the sliding block 44 is installed on the support rod 5 .

[0040] It can be understood that the driving mechanism 3 is capable of driving the first covering shell 41 to move, so that the first covering shell 41 and the second covering shell 61 are brought closer to each other.

[0041] The push rod motor 45 is installed on the installation box 1 , and the output shaft of the push rod motor 45 is connected to the connecting rod 42 . The connecting rod 42 passes through one side of the first cover shell 41 , and the pressure plate 43 is installed on one side of the connecting rod 42 .

[0042] It should be noted that, in this embodiment, the first cover shell 41 is controlled to move through the driving mechanism 3, and the pressure plate 43 is clamped and pressed toward the baffle 64 through the push rod motor 45, so that the clamping and blocking actions do not interfere with each other, are not limited by the size of the workpiece, and do not take up too much space.

[0043] In one embodiment of the present invention, Figure 1 As shown, the second clamping mechanism 6 may include a second cover shell 61 , a mounting block 62 , a stud 63 and a baffle 64 .

[0044] The mounting blocks 62 are arranged on both sides of the second cover shell 61 , the studs 63 pass through the surface of the second cover shell 61 , and the other side of the studs 63 is connected to the baffle 64 .

[0045] It can be understood that the second clamping block adjusts the position of the baffle 64 by the extended length of the stud 63, so that the positions of different workpieces can be exposed to the slots for laser cutting.

[0046] In one embodiment of the present invention, Figure 1 As shown, the driving mechanism 3 may include a rotating motor 31 , a threaded rod 32 , a moving block 33 , a bearing block 34 and a cross bar 35 .

[0047] The output shaft of the rotating motor 31 is connected to the threaded rod 32 , the bearing block 34 is installed between the cross bar 35 and the threaded rod 32 , the moving block 33 is installed on the threaded rod 32 , and the moving block 33 is connected to the fixed block 46 .

[0048] It is understandable that the rotating motor 31 can drive the threaded column to rotate, thereby driving the moving block 33, and cooperating with the sliding block 44 to drive the first cover shell 41 to move, thereby realizing the splicing of the first cover shell 41 and the second cover shell 61.

[0049] In one embodiment of the present invention, Figure 1 As shown, the laser cutting mechanism 7 may include a support block 71 , an extension rod 72 , an electric slider 73 and a laser head 74 .

[0050] The support block 71 is mounted on the support rod 5 , the extension rod 72 is mounted on the support block 71 , the electric slider 73 is mounted on the extension rod 72 , and the laser head 74 is mounted on the bottom of the electric slider 73 .

[0051] It should be noted that the electric slider 73 can drive the laser head 74 to move to different positions, and the laser head 74 can perform laser cutting on the workpiece.

[0052] In summary, the laser cutting processing fixture of the embodiment of the utility model can achieve more effective heat dissipation during the cutting process, can reduce the thermal deformation of the cutting piece during the processing process, and improve the accuracy and stability of laser cutting. At the same time, it can reduce the emission of dust and smoke in the air and extend the service life of the equipment.
