[0029] The following is combined with the attached Figure 1 - Figure 2The following further describes the present application with specific embodiments:

[0030] First of all, it should be noted here that in the description of the present application, when terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other orientation words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings.

In addition, in the present application, unless otherwise clearly specified and limited, when terms such as "installation", "connection", "connection" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limit connections, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium; therefore, for those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] As Figures 1 to 2 shown, a laser cutting protection device includes: a moving table 2, a linear screw module 3, a clamping assembly 4, a fixed rod 5 and a protection gasket 6. The linear screw module 3 is fixed on the moving table 2, and the guide rail of the linear screw module 3 is arranged along the length direction of the moving table 2; the clamping group is fixed on the slider 31 of the linear screw module 3; the fixed rod 5 is fixed on the clamping assembly 4, and the fixed rod 5 is arranged along the moving direction of the slider 31; the protection gasket 6 is fixed at the free end of the fixed rod 5.

[0032] In the present application, when performing the operation of laser cutting a pipe, first place the laser cutting protection device in a suitable position. The linear screw module 3 is fixed on the moving table 2, and its slider 31 can move along the length direction of the moving table 2 on the guide rail. The clamping assembly 4 is fixed on the slider 31 of the linear screw module 3 and moves along with the movement of the slider 31. The fixed rod 5 is fixed on the clamping assembly 4, and the protection gasket 6 is fixed at the free end of the fixed rod 5. Before the laser cutting starts, drive the slider 31 to move through the linear screw module 3, so that the protection gasket 6 moves to the position of the pipe to be cut, and insert the protection gasket 6 into the pipe, which plays a role in blocking the splashing of locally melted substances generated during laser cutting into the inside of the pipe.

[0033] This device can automatically insert the protection gasket 6 into the pipe without manual operation, saving the time of manually inserting the protection gasket 6, enabling continuous cutting work during laser cutting, greatly improving the production efficiency, and can also be automatically withdrawn from the pipe body after cutting and continue to be inserted into the pipe body for processing during subsequent cutting.

[0034] Specifically, it further includes a base 7. A rail 71 is fixed on the base 7. The moving platform 2 is slidably arranged on the rail 71, and the moving direction of the moving platform 2 is perpendicular to the moving direction of the slider 31.

[0035] The moving platform 2 can slide on the rail 71 perpendicular to the moving direction of the slider 31, which can conveniently adjust the position of the moving platform 2 and directly move it away when not in use.

[0036] Specifically, a plurality of protective covers 8 are hinged on the moving platform 2, and the protective covers 8 can cover the linear screw module 3.

[0037] During the operation of the device, the protective cover 8 can prevent the operator from accidentally contacting the operating linear screw module 3, reducing the risk of personal injury. At the same time, it also avoids abnormal operation of the device caused by accidental touch, improving the safety of the workplace.

[0038] Specifically, the protective gasket 6 is arc-shaped.

[0039] Due to good fitting with the inner wall of the pipe fitting, during the laser cutting process, the arc-shaped protective gasket 6 is not prone to shaking or displacement, and has a wrapping effect. The splashed substances can move towards the central position of the protective gasket 6 after hitting it.

[0040] Specifically, there are two clamping assemblies 4. The clamping assembly 4 includes a frame body 41. The frame body 41 is fixed on the slider 31. The frame body 41 has a placement hole 411. A first clamping block 42 and a second clamping block 43 are arranged in the placement hole 411. The first clamping block 42 is provided with a first clamping groove 421, and the second clamping block 43 is provided with a second clamping groove 431. The first clamping groove 421 and the second clamping groove 431 are used to clamp the fixing rod 5. A regulating nut 44 is threadedly connected to the slider 31, and the end of the regulating nut 44 can extend into the placement hole 411 and abut against the second clamping block 43.

[0041] Place the fixing rod 5 in the placement hole 411 of the frame body 41, between the first clamping block 42 and the second clamping block 43. By rotating the regulating nut 44 on the slider 31, its end extends into the placement hole 411 and gradually abuts against the second clamping block 43. As the regulating nut 44 is continuously screwed in, the second clamping block 43 moves towards the first clamping block 42, so that the first clamping groove 421 of the first clamping block 42 and the second clamping groove 431 of the second clamping block 43 gradually clamp the fixing rod 5, thereby realizing the clamping and fixing of the fixing rod 5.

[0042] By adjusting the extrusion effect of the adjusting nut 44 on the first clamping block 42 and the second clamping block 43, a large clamping force can be generated to ensure that the fixing rod 5 is firmly fixed in the clamping assembly 4. The magnitude of the clamping force can be adjusted by the degree of screwing in of the adjusting nut 44, so as to adapt to fixing rods 5 of different diameters. The operations of clamping and disassembling the fixing rod 5 are very simple and can be completed only by rotating the adjusting nut 44. In actual use, the operator can quickly replace the fixing rod 5 or the protective gasket 6, improving work efficiency and reducing operation time and labor intensity.

[0043] Specifically, the frame body 41 includes a first frame 412 and a second frame 413, and the first frame 412 and the second frame 413 are detachably connected.

[0044] When it is necessary to install or replace the components inside the clamping assembly 4, the first frame 412 and the second frame 413 can be disassembled for easy operation.

[0045] Specifically, there is a gap between the two clamping assemblies 4.

[0046] The fixing rod 5 can be clamped at two positions by the two clamping assemblies 4, making the clamping of the fixing rod 5 more stable.

[0047] It should be noted that the above embodiments are only used to illustrate the present application and do not limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the art can still modify the present application or make equivalent substitutions.
