[0029] Before explaining any implementation manner of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0030] In the present application, the terms "comprise", "include", "have" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0031] In the present application, the term "and / or" describes an associative relationship of associated objects and indicates that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump may represent: the sole existence of a centrifugal vortex magnetic pump, the simultaneous existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, and the sole existence of a centrifugal vortex magnetic pump. Additionally, in the present application, the character " / " generally represents an "and / or" relationship between the associated objects before and after.

[0032] In the present application, the terms "connect", "combine", "couple", "mount" may be direct connection, combination, coupling or mounting, or may be indirect connection, combination, coupling or mounting. Among them, by way of example, direct connection means that two parts or components are connected together without the need for an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling and may include electrical connection or coupling.

[0033] In this application, those of ordinary skill in the art will understand that relative terms used in connection with quantities or conditions (such as "about", "approximately", "substantially", etc.) are intended to include the recited value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with a particular value due to manufacturing, assembly, use, etc. Such terms should also be considered to disclose ranges defined by the absolute values of two endpoints. Relative terms may refer to a plus or minus of a certain percentage (such as 1%, 5%, 10% or more) of the indicated value. Numerical values without the use of relative terms should also be disclosed as specific values with tolerances. In addition, when expressing relative angular positional relationships (such as substantially parallel, substantially perpendicular), "substantially" may refer to a plus or minus of a certain number of degrees (such as 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0034] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0035] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", "rear", etc. are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of this application.

It should also be understood that orientation terms such as upper side, lower side, left side, right side, front side, rear side, etc. not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side may include directly below, lower left, lower right, lower front, and lower rear, etc.

[0036] Please refer to Figures 1 to 3 , this embodiment provides a laser nozzle mounting mechanism, which includes a carrier 1, a first level 2, a second level 3, and a connection component 4.

[0037] Among them, the carrier 1 is used to install the laser nozzle 100 on the frame. In this embodiment, the carrier 1 is screwed to the back of the housing of the laser nozzle 100. The first level 2 is arranged on the laser nozzle 100 along the first direction, and the first level 2 is configured to detect the levelness of the laser nozzle 100 in the first direction. The second level 3 is arranged on the laser nozzle 100 along the second direction, and the second level 3 is configured to detect the levelness of the laser nozzle 100 in the second direction. The first horizontal direction is perpendicular to the second horizontal direction. The connection assembly 4 is arranged between the carrier 1 and the frame. The connection assembly 4 is configured to connect the carrier 1 to the frame and make the relative position between the carrier 1 and the frame adjustable.

[0038] It can be understood that the levelness of the laser nozzle 100 is detected by the first level 2 and the second level 3. In combination with this embodiment, the first level 2 and the second level 3 cooperate to determine the levelness of the laser nozzle 100 on the horizontal plane, so as to accurately reflect the position state of the laser nozzle 100 after being installed on the frame, which is more convenient for the staff to adjust the position of the laser nozzle 100, and thus helps to improve the installation accuracy of the laser nozzle 100.

[0039] It should be noted that both the first level 2 and the second level 3 are existing technologies, and the models of the first level 2 and the second level 3 can be selected according to the actual application scenarios. This embodiment does not make specific requirements and restrictions on this.

[0040] To improve the convenience for the staff to observe the first level 2 and the second level 3, both the first level 2 and the second level 3 are arranged on the top surface of the laser nozzle 100.

[0041] Specifically, a first accommodation groove 5 and a second accommodation groove 6 are provided on the top surface of the laser nozzle 100. The first level 2 is embedded in the first accommodation groove 5, and the second level 3 is embedded in the second accommodation groove 6. It can be understood that the settings of the first accommodation groove 5 and the second accommodation groove 6 can play a certain protective role for the first level 2 and the second level 3, so as to avoid damage to the first level 2 and the second level 3 due to bumps. It can also be understood that the first accommodation groove 5 and the second accommodation groove 6 also provide an installation position for the first level 2 and the second level 3 respectively, which is more convenient for installing the first level 2 and the second level 3, and has a simple structure and low production cost.

[0042] In this embodiment, the structures of the first accommodation groove 5 and the second accommodation groove 6 are the same. The structure of the first accommodation groove 5 will be described below as an example. An arc transition surface is provided at the notch of the first accommodation groove 5. With this setting, it can play a guiding role for the first level 2 when the first level 2 is embedded in the first accommodation groove 5, which is more convenient for operation. It should be noted that the arc transition surface can be made by chamfering process and will not be elaborated.

[0043] Furthermore, the connecting component 4 includes an adjusting through hole 41 and a locking bolt arranged on the carrier 1. The locking bolt can penetrate through the adjusting through hole 41 and be screwed onto the frame body to lock the carrier 1 to the frame body. There are two adjusting through holes 41, and the two adjusting through holes 41 are arranged in the vertical direction, and correspondingly, there are two locking bolts.

[0044] It can be understood that locking the carrier 1 to the frame body through the locking bolt is convenient for operation, has a simple structure, and low usage cost. It should be noted that the verticality of the laser nozzle 100 usually does not deviate much. In combination with this embodiment, the adjustment can be achieved by adjusting the locking degree of the corresponding locking bolt. Exemplarily, if the upper side of the laser nozzle 100 inclines outward, further tightening the upper side locking bolt or loosening the lower side locking bolt can achieve the adjustment of the verticality of the laser nozzle 100.

[0045] Furthermore, the two adjusting through holes 41 form a set of adjusting hole groups, and there are two sets of adjusting hole groups arranged in the horizontal direction. With such a setting, the connection between the carrier 1 and the frame body can be made more reliable. Of course, in other embodiments, the adjusting hole groups can also be set to three groups, four groups or more groups, and no specific requirements and limitations are made in this regard.

[0046] It should be noted that the verticality of the laser nozzle 100 is also affected by the machining errors of one or more of the laser nozzle 100, the frame body and the carrier 1, and the adjustment stroke achieved by only loosening or tightening the upper and lower locking bolts cannot cover the maximum deviation value of the verticality of the laser nozzle 100. For this reason, in this embodiment, the connecting component 4 further includes a plurality of gaskets, and the gaskets can be disposed between the carrier 1 and the frame body to adjust the angle of the carrier 1 around the horizontal direction. It should be noted that the thickness of a single gasket can be selected according to the actual application scenario, such as 1 mm, 2 mm, etc.

[0047] To better dispose the gasket between the carrier 1 and the frame body, the carrier 1 includes a mating surface that can fit onto the frame body. With such a setting, both sides of the gasket can respectively fit the mating surface and the side surface of the carrier 1.

[0048] Furthermore, the adjusting through hole 41 is a counterbore, and the head of the locking bolt can be accommodated in the counterbore of the counterbore. It can be understood that by accommodating the head of the locking bolt in the counterbore of the counterbore, the head of the locking bolt will not protrude from the surface of the carrier 1, thereby avoiding the situation where the locking bolt rotates due to accidental contact.

[0049] In addition, this embodiment further provides a laser cutting machine, which includes a frame body, a laser nozzle 100, and the above-mentioned laser nozzle mounting mechanism. The laser nozzle 100 is mounted on the frame body through the laser nozzle mounting mechanism. It can be understood that the mounting accuracy of the laser nozzle 100 of the laser cutting machine including the above-mentioned laser nozzle mounting mechanism is higher.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
