[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an element in the middle. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an element in the middle at the same time. In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments, such as "inside", "outside", "left", "right" and similar expressions are only for the purpose of explanation and are not intended to limit the present invention.

[0025] Please refer to Figures 1 to 6 , is a schematic diagram of a flexible mounting mechanism 100 of a laser cutting head of the present invention, wherein Figure 7 The flexible mounting mechanism 100 of the laser cutting head is installed with the laser cutting head 200. The flexible mounting mechanism 100 of the laser cutting head comprises a support frame 20, a fixing seat 30 mounted on the support frame 20, a receiving seat 40 magnetically fixed to the fixing seat 30, and a protective rope 50 installed between the fixing seat 30 and the receiving seat 40. The receiving seat 40 is connected to the laser cutting head 100.

[0026] Furthermore, the fixing seat 30 is provided with a magnet block 301, and the receiving seat 40 is made of ferromagnetic material, so that the receiving seat 40 can be well magnetically fixed to the fixing seat 30. In another embodiment, the receiving seat 40 is provided with a magnet block 301, and the fixing seat 30 is made of ferromagnetic material, so that the receiving seat 40 can be well magnetically fixed to the fixing seat 30. In other embodiments, the fixing seat 30 and the receiving seat 40 can both be provided with magnet blocks, as long as the magnetism of the magnet block on the fixing seat 30 is different from the magnetism of the magnet block on the receiving seat 40.

[0027] Furthermore, a protrusion 31 is provided on the fixing seat 30, and a groove 41 adapted to the protrusion 31 is provided on the receiving seat 40, wherein the cross-sections of the protrusion 31 and the groove 41 are triangular, so that the protrusion 31 plays a certain guiding role, and the receiving seat 40 can be quickly and orderly fixed on the fixing seat 30 under the action of magnetic attraction.

[0028] Furthermore, a proximity switch 32 is installed on the fixing seat 30, and a proximity switch sensing plate 42 is installed on the receiving seat 40, and the proximity switch sensing plate 42 is arranged opposite to the proximity switch 32. During use, if the laser cutting head 200 detaches from the fixing seat 30 with the receiving seat 40 after hitting an object, the proximity switch sensing plate 42 separates from the proximity switch 32, and the proximity switch 32 will disconnect the power supply at this time, so that the entire machine tool stops working, and the protection is good. In this embodiment, the number of the proximity switch 32 and the proximity switch sensing plate 42 are both two, so that dual sensing control is realized, and the accuracy is further guaranteed.

[0029] In this embodiment, the protection rope 50 is a steel wire rope, and in other embodiments, it can also be a cotton rope, a hemp rope, etc., which are not limited here. There are two protection ropes 50 in this embodiment, which are symmetrically installed on the fixing seat 20 and the receiving seat 40.

[0030] Furthermore, the flexible mounting mechanism 100 of the laser cutting head also includes a lifting driver 60 mounted on the support frame 20, and an adapter seat 70 connected to the lifting driver 60, and the adapter seat 70 is connected to the fixed seat 20. Through the arrangement of the lifting driver 60 and the adapter seat 70, the fixed seat 30, the receiving seat 40, and the laser cutting head 200 can be driven to move up and down. In one embodiment, a threaded rod 61 is installed on the lifting driver 60, and the adapter seat 70 is a threaded seat and is sleeved with the threaded rod 61. At this time, the lifting driver 60 is a servo motor, which can drive the threaded rod 61 to rotate forward and reverse, and then drive the adapter seat 70 to rise or fall. In other embodiments, the lifting driver 60 can also be a telescopic cylinder, and the telescopic rod of the telescopic cylinder is connected to the adapter seat 70, and the telescopic rod is driven to extend and retract by the telescopic cylinder to complete the lifting action.

[0031] Further, the inner wall of the support frame 20 is provided with a guide rail groove 21, and the outer wall of the adapter 70 is provided with a guide rail 71 adapted to the guide rail 21, so that the adapter 70 is very stable when moving up and down on the support frame 20. In this embodiment, the number of the guide rail groove 21 and the number of the guide rail 71 are both two.

[0032] Furthermore, a limiting baffle 72 is provided on the adapter seat 70, and the limiting baffle 72 abuts against the outer wall of the support frame 20, so as to limit the adapter seat 70, making it more stable and less likely to loosen when moving.

[0033] The flexible installation mechanism 100 of the laser cutting head mentioned above is installed with the support frame 20 connected to the mechanical arm of the machine tool, and the laser cutting head 200 is connected and fixed to the receiving seat 40. When in use, the mechanical arm moves the laser cutting head 200 on the machine tool and performs laser cutting on the material. Since the fixing seat 30 and the receiving seat 40 are fixed by magnetic attraction, they have a certain flexibility. When the laser cutting head 200 collides with other objects during operation, it will separate from the fixing seat 30 with the receiving seat 40 to overcome the magnetic attraction force, and the laser cutting head 200 will not be damaged due to hard collision. Moreover, the provision of the protective rope 50 can prevent the laser cutting head 200 from falling and breaking after separating from the fixing seat 30 with the receiving seat 40, and the protective performance is good.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
