DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 2 A laser cutting head comprises a mounting plate 1, a connecting plate 2 is fixedly mounted on the mounting plate 1, a cutting head 11 is fixedly mounted on the connecting plate 2, and a locking mechanism is installed between the connecting plate 2 and the mounting plate 1;

[0023] The following points are worth noting:

[0024] The clamping mechanism includes a clamping plate 3, a clamping slot 4, a slider 5, a nut 9 and a screw 10. Two sliders 5 are slidably mounted on the connecting plate 2. A sliding slot 8 matching the two sliders 5 is provided on the connecting plate 2. A linkage structure is installed between the two sliders 5. A clamping plate 3 is fixedly mounted on each of the two sliders 5. A clamping slot 4 matching the two clamping plates 3 is provided on the mounting plate 1. A screw 10 is fixedly mounted on one of the sliders 5. A nut 9 connected to the screw 10 by thread rotation is rotatably mounted on the connecting plate 2.

[0025] Rotating the nut 9 moves the screw rod 10, thereby driving the slider 5 fixedly connected to the screw rod 10 to move, so that the clamping plate 3 on the slider 5 engages with the clamping groove 4, so as to install the connecting plate 2. Compared with the original direct use of bolts to fix the connecting plate 2 and the mounting plate 1, direct force on the bolts can be avoided, thereby extending the service life of the bolts.

[0026] A plurality of pillars are fixedly mounted on the nut 9, a rotating block is fixedly mounted on each pillar, and an annular groove matching with the plurality of rotating blocks is provided on the connecting plate 2;

[0027] The rotation of the nut 9 drives the pillar to rotate, and the rotation of the pillar drives the rotating block to slide in the annular groove. The friction between the rotating block and the annular groove is small, which facilitates the rotation of the nut 9 and avoids direct contact between the nut 9 and the connecting plate 2, which can effectively extend the service life of the nut 9.

[0028] The linkage structure includes a rack 7 and a gear 6. The gear 6 is rotatably mounted on the connecting plate 2, and a rack 7 meshing with the gear 6 is fixedly mounted on each of the two sliders 5.

[0029] When the slider 5 fixedly connected to the screw 10 moves, it drives the rack 7 on the slider 5 to move. The movement of the rack 7 drives the gear 6 meshing with it to rotate. The rotation of the gear 6 drives the other rack 7 meshing with it to move in the opposite direction, so that the other slider 5 moves in the opposite direction to the slider 5. The two sliders 5 move in the opposite direction at the same time, which can ensure that the center line of the connecting plate 2 and the center line of the mounting plate 1 are located on the same vertical line, avoid the situation where the connecting plate 2 and the mounting plate 1 are offset due to wear of the clamping plate 3, and ensure that the position of the cutting head 11 remains unchanged, thereby improving the cutting quality.

[0030] Two fixed blocks 12 are fixedly mounted on the connecting plate 2, a slide bar 13 is fixedly mounted on each of the two fixed blocks 12, a slide sleeve 14 is slidably mounted on each of the two slide bars 13, and a locking mechanism is installed between each of the two slide bars 13 and the corresponding slide sleeve 14;

[0031] The above are worth noting:

[0032] The locking mechanism includes an insertion rod 18, a spring 19 and a slot 20. The insertion rod 18 is slidably mounted on the sliding sleeve 14. The spring 19 is fixedly mounted between the insertion rod 18 and the sliding sleeve 14. The sliding rod 13 is provided with two slots 20 that match the insertion rod 18.

[0033] Pull the rod 18 out of the slot 20, then pull up the sleeve 14, which can drive the cover 15 to move, and then insert the rod 18 into another slot 20 under the action of the spring 19 to lock the sleeve 14. At this time, the cover 15 is also fixed. This is to shift and fix the cover 15 to improve the stability of the cover 15.

[0034] A cover body 15 matching with the cutting head 11 is fixedly mounted on the two sliding sleeves 14. A square hole is provided at the bottom of the cover body 15. Two rotating shafts are fixedly mounted in the square hole. A sealing door 16 is rotatably mounted on each of the two rotating shafts. A spring ring is fixedly mounted between the two sealing doors 16 and the corresponding rotating shafts. An automatic opening mechanism is installed between the cutting head 11 and the sealing door 16.

[0035] The above are worth noting:

[0036] 1. The opening mechanism includes a lever 17. Two levers 17 are fixedly mounted on the cutting head 11 and are matched with corresponding sealing doors 16;

[0037] As the cover body 15 moves upward, the sealing door 16 will be pushed open under the action of the push rod 17. At this time, the cutting head 11 can emit laser for cutting, thereby achieving the purpose of automatically opening the sealing door 16. There is no need to lock the sealing door 16, and the operation is convenient.

[0038] The function of the spring ring is to reset the sealing door 16, so that the sealing door 16 can rotate automatically when the cover body 15 is in the next process, without manual rotation, and is more convenient to use.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
