Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] To solve the problem that the position of an object is prone to shift during the engraving process, resulting in inaccurate engraving accuracy, please refer to Figures 1 - 7, a large-scale high-precision laser engraving machine provided in this embodiment includes a frame 10. An elevating assembly 20, a translation assembly 30, and an engraving assembly 50 for engraving an object are arranged inside the frame 10. The translation assembly 30 is used to carry the object to be engraved, the elevating assembly 20 is used to drive the translation assembly 30 to adjust its position, and clamping assemblies 40 for fixing the engraved object are installed at both ends above the translation assembly 30;
[0029] The clamping assembly 40 includes a protective shell 41 fixedly connected to the translation assembly 30. The protective shell 41 is used to protect its internal structure. One end of the protective shell 41 is fixedly connected to a second motor 42. The second motor 42 serves as the power source for the sliding of a first sliding block 45. The output shaft of the second motor 42 is fixedly connected to a bidirectional screw 43 rotatably arranged inside the protective shell 41. Opposite threads are provided at both ends of the bidirectional screw 43. A first limiting rod 44 fixed inside the protective shell 41 is arranged on one side of the bidirectional screw 43. Symmetrically arranged first sliding blocks 45 are threadedly connected to the bidirectional screw 43. The first sliding blocks 45 slide on the first limiting rod 44. Support rods 46 are symmetrically and rotatably connected inside the first sliding blocks 45. The other ends of the two groups of support rods 46 are rotatably connected to clamping plates 47. A spring 471 is fixedly connected to the clamping plate 47. One end of the spring 471 is fixedly connected to a fitting plate 472. Place the object to be engraved on the translation assembly 30, start the second motor 42. When the output shaft of the second motor 42 drives the bidirectional screw 43 to rotate, the first sliding blocks 45 slide on the bidirectional screw 43 under the restriction of the first limiting rod 44. Through the sliding of the first sliding blocks 45, the support rods 46 inside the first sliding blocks 45 rotate to adjust their angles and positions, so that the support rods 46 push the clamping plates 47 towards the object on the translation assembly 30. Through the corresponding movement of the two groups of clamping plates 47, the object on the translation assembly 30 above is clamped, and the fitting plate 472 can fit the surfaces of objects with different shapes under the action of the spring 471 on the clamping plate 47.
[0030] Considering that the object to be engraved needs to be moved to the translation assembly 30 and adjusted to a suitable height for engraving the object, refer to Figures 1 - 3, the lifting assembly 20 includes a first hydraulic cylinder 21 fixedly connected inside the frame 10. The first hydraulic cylinder 21 serves as a power source. The movable end of the first hydraulic cylinder 21 is rotatably connected to a first gear 22. A first chain 23 is engaged with the first gear 22. One end of the first chain 23 is fixedly connected to a fixed block 24, and the fixed block 24 is fixed inside the frame 10. One end of the first hydraulic cylinder 21 is fixedly connected to a fixed rod 25, and the fixed rod 25 is fixed inside the frame 10. A connecting plate 26 slides on the fixed rod 25. One end of the first chain 23 is fixedly connected to the connecting plate 26. One end of the first hydraulic cylinder 21 is fixedly connected to a fixed rod 25, and the fixed rod 25 is fixed inside the frame 10. A connecting plate 26 slides on the fixed rod 25. The connecting plate 26 is fixed to the other end of the first chain 23. Before moving the object to be carved onto the translation assembly 30, the lifting assembly 20 can drive the translation assembly 30 to descend to the bottom end of the frame 10 to facilitate moving the object onto the translation assembly 30. After placing the object on the translation assembly 30, start the first hydraulic cylinder 21 to make its movable end push the first gear 22 to move vertically. Under the action of the first chain 23, the first gear 22 will rotate when moving vertically. By the rotation of the first gear 22, the connecting plate 26 fixedly connected to one end of the first chain 23 drives the translation assembly 30 to adjust its position following the movable end of the first hydraulic cylinder 21.
[0031] Considering that after carving the object, it is necessary to move the object away onto the translation assembly 30 and continue to load materials onto the translation assembly 30. Refer to Figures 1 - 4 , therefore, the translation assembly 30 includes a storage rack 31 fixedly connected to the connecting plate 26. The storage rack 31 is provided with an inner cavity. A plurality of rotating shafts 32 are rotatably connected inside the inner cavity. One end of the rotating shaft 32 is fixedly connected to a second gear 33. A second chain 34 is engaged with the second gear 33. A first sliding plate 35 fixedly connected to the end of the storage rack 31 is slidably installed on the frame 10. A first motor 36 for driving one of the rotating shafts 32 to rotate is installed on the first sliding plate 35. The first motor 36 serves as the power source for the rotation of the rotating shaft 32. When the object needs to be moved onto the storage rack 31 and continue to load materials onto the storage rack 31 after carving, start the first motor 36. Under the rotation of the first motor 36, the rotating shaft 32 rotates. Under the action of the second gear 33 and the second chain 34, the rotating shafts 32 inside the rotating storage rack 31 rotate in the same direction. By the rotation of the rotating shaft 32, the object placed on its surface can be conveyed, so that the object can move out of the storage rack 31 at one end of the storage rack 31 and continue to load materials at the other end of the storage rack 31, reducing manual operation and improving work efficiency.
[0032] Considering that it is necessary to carve the object on the translation assembly 30. Refer to Figure 1 and Figures 6 - 7, therefore, the engraving component 50 includes a second sliding plate 51 that slides inside the frame 10. The second sliding plate 51 is used to carry the laser transmitter 54. A second hydraulic cylinder 52 is fixedly connected to the second sliding plate 51, and the second hydraulic cylinder 52 is fixedly installed at the upper end of the frame 10. The second hydraulic cylinder 52 is used to adjust the height of the laser transmitter 54. A second sliding block 53 is slidably connected inside the second sliding plate 51. The laser transmitter 54 is fixedly connected below the second sliding block 53. A transmission component 55 is provided inside the second sliding plate 51.

One end of the reciprocating screw 551 is fixedly connected to a third motor 553 installed on the second sliding plate 51. When engraving an object on the translation component 30, start the second hydraulic cylinder 52 to drive the laser transmitter 54 on the second sliding plate 51 to approach the object on the translation component 30. Under the operation of the numerical control computer, the laser transmitter 54 can work to emit laser, and under the rotation of the third motor 553, the second sliding block 53 slides on the reciprocating screw 551 under the restriction of the second limiting rod 552, so as to realize the laser transmitter 54 sliding with the second sliding block 53 to change its position to meet the requirements of the engraving style of the object.
