Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine with high cutting surface flatness. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system; the laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal; as the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] When existing laser cutting machines are processing sheet metal parts, in most cases the sheet metal parts are directly placed on the processing table. However, due to the lack of fixation of the sheet metal parts, the sheet metal parts are easily affected by external forces during the processing, causing the sheet metal parts to loosen and shift in position, resulting in reduced flatness of the cut surface, affecting the overall accuracy of the sheet metal parts. Therefore, a laser cutting machine with high cutting surface flatness is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

The top end of the connecting rod 7 is fixedly connected with a connecting plate 8. The top end of the connecting plate 8 is fixedly connected with a clamping cylinder 9. The bottom end of the output shaft of the clamping cylinder 9 is fixedly connected with a clamping plate 10. The top end of the clamping plate 10 is fixedly connected with a limiting component 11.

[0026] The height of the gantry is higher than the height of the clamping cylinder 9, so that the sheet metal part can be laser cut by the laser cutting head.

[0027] The clamping assembly 6 includes a threaded sleeve 61 fixedly connected to the right side of the first sliding block 4 , the inner side of the threaded sleeve 61 is connected to a threaded rod 62 via threaded transmission, and the left end of the threaded rod 62 is rotatably connected to a clamping plate 63 .

[0029] By rotating the rotating block 13, the threaded rod 62 can be moved left and right, thereby driving the clamping plate 63 to move left and right. The outer side of the first sliding block 4 can be restricted to the outer side of the limiting sliding rod 3 through the clamping plate 63, thereby fixing the position of the connecting plate 8.

[0030] The limiting assembly 11 includes a limiting rod 111 fixedly connected to the top of the clamping plate 10 , a limiting hole 112 is provided at the top of the connecting plate 8 , and the top of the limiting rod 111 is fixedly connected to a limiting block 113 .

[0032] The limiting assembly 11 can limit the movement of the clamping plate 10 , effectively preventing the clamping plate 10 from being displaced during the up and down movement, thereby improving the stability of the movement of the clamping plate 10 .

[0033] There are two first sliding blocks 4 on the outer side of the right-side limiting sliding rod 3 , two second sliding blocks 5 on the outer side of the left-side limiting sliding rod 3 , and two clamping plates 10 .

[0035] Working principle:

[0036] First, place the sheet metal to be laser cut on the top of the laser cutting table 1, and rotate the rotating block 13 to move the threaded rod 62 left and right, thereby driving the clamping plate 63 to move left and right, so that the clamping plate 63 contacts the limit of the right limit slide bar 3, and move the connecting plate 8 to the top of the sheet metal;

[0037] Then: rotate the rotating block 13 so that the clamping plate 63 is re-limited to the outside of the right limiting slide rod 3, start the clamping cylinder 9, so that the clamping plate 10 moves up and down, and then the clamping pad 12 will be squeezed with the top of the sheet metal, and the two ends of the sheet metal are fixed by the two clamping pads 12, which effectively prevents the sheet metal from shifting in position during the processing and improves the flatness of the cut surface of the sheet metal.
