Detailed Implementation

[0021] Example 1

[0022] As shown in Figures 1-4, the laser cutting equipment proposed in this embodiment includes a base 1 and a fixing device; a cutting table 2 is provided on the base 1.

[0023] The fixing device includes a fixing seat 3 with multiple linearly arranged support plates 11 on the cutting table 2, a threaded rod 4 threadedly connected to the fixing seat 3, two symmetrically distributed guide rods 5 slidably connected to the fixing seat 3, a flat clamping plate 6 on the guide rod 5, a rotating connector 7 on the flat clamping plate 6, and a support frame 9 on the cutting table 2; one end of the threaded rod 4 is inserted into the interior of the rotating connector 7 and rotatably connected; the cutting table 2 is provided with a groove 12; the support frame 9 is provided with a fixing device, which includes an arc-shaped clamping plate 10 located directly above the groove 12 and provided with an elastic anti-slip pad; and a handwheel 8 is provided at the end of the threaded rod 4 away from the rotating connector 7.

[0024] In this embodiment, when a stainless steel plate needs to be cut, the stainless steel plate is first placed on the support plate 11, and then the threaded rod 4 is rotated by the handwheel 8. The threaded rod 4 engages with the fixed seat 3 and rotates with the rotating connector 7. Under the guidance of the guide rod 5, the threaded rod 4 drives the flat clamping plate 6 to move closer to the stainless steel plate through the rotating connector 7. With the cooperation of two people, the two sides of the stainless steel plate are clamped. When a stainless steel pipe needs to be cut, the stainless steel pipe is first placed in the groove 12, and then the threaded rod 4 is rotated by the handwheel 8. Through the same transmission method as fixing the stainless steel plate, the arc-shaped clamping plate 10 moves downward until both ends of the stainless steel pipe are clamped. The elastic anti-slip pads ensure that the contact area between the arc-shaped clamping plate 10 and the stainless steel pipe is large enough to ensure the stability of the stainless steel pipe. This achieves a good fixing and clamping effect on the stainless steel plate and stainless steel pipe, ensuring the stability of the workpiece during cutting. The operation is simple and convenient, and it has good practicality.

[0025] Example 2

[0026] As shown in Figures 1, 3, and 4, the laser cutting equipment proposed in this embodiment, compared with the first embodiment, has a movable frame 17 above the base 1, a mounting base 20 slidably connected to the movable frame 17, and a cutting mechanism on the mounting base 20. The cutting mechanism includes a cylinder 21 mounted on the mounting base 20, a lifting seat 22 driven and connected to the cylinder 21, and a laser cutter 23 mounted on the lifting seat 22.

[0027] The drive mechanism on the base 1 includes two mounting brackets 13 distributed on the left and right, a first motor 14 mounted on one mounting bracket 13, a first lead screw 15 rotatably connected to the mounting bracket 13, a crossbar 16 mounted on the other mounting bracket 13, a second motor 18 mounted on a movable bracket 17, and a second lead screw 19 rotatably connected to the movable bracket 17; the first motor 14 and the first lead screw 15 are drivenly connected, the first lead screw 15 and the first motor 14 are threadedly connected, the movable bracket 17 is slidably connected to the crossbar 16, the second motor 18 and the second lead screw 19 are drivenly connected, and the mounting base 20 and the second lead screw 19 are threadedly connected.

[0028] In this embodiment, when cutting, the first motor 14 drives the first lead screw 15 to rotate, so that the first lead screw 15 and the moving frame 17 are screwed together. Under the guidance of the crossbar 16, the moving frame 17 moves along the axial direction of the first lead screw 15. The second motor 18 drives the second lead screw 19 to rotate, so that the second lead screw 19 is screwed together with the mounting base 20, so that the mounting base 20 moves along the axial direction of the second lead screw 19. At the same time, the cylinder 21 drives the laser cutting machine 23 to lift and lower, thereby realizing the all-round position adjustment of the laser cutting machine 23.

[0029] Example 3

[0030] As shown in Figure 4, in this embodiment of the laser cutting equipment, compared with the second embodiment, the laser cutting machine 23 is provided with a cover 24, the cover 24 is provided with a connecting rod 25, the connecting rod 25 is provided with a fixing plate 26, and six bolts 27 arranged in a ring array are provided through the fixing plate 26. The bolts 27 are threadedly connected to the mounting base 20.

[0031] The mounting base 20 is provided with a fumigation assembly, which includes a fumigation pipe 28 disposed on the mounting base 20, a dust collection hood 30 disposed inside the cover 24, and a conduit 29 for connecting the fumigation pipe 28 and the dust collection hood 30.

[0032] In this embodiment, during cutting, the hood 24 prevents the fumes generated during cutting from quickly dissipating into the surrounding air. At the same time, the fume hood 28, duct 29, and dust hood 30 quickly absorb and treat the fumes around the hood 24, ensuring the health of the workers. Furthermore, the hood 24 can be quickly installed and disassembled using the connecting rod 25, fixing plate 26, and bolts 27, facilitating the inspection and maintenance of the cutting mechanism and fume extraction components.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
