[0051] The clamping mechanism 1 comprises a supporting piece 11, a pressing block 12 and a buckling piece 13, the supporting piece 11 is used for being connected with the equipment body 2, and at least one of the following connection modes can be adopted, for example, bolt connection, clamping, insertion, bonding, magnetic attraction connection and binding fixation. The supporting piece 11 is provided with a first end 111 and a second end 112 which are arranged at intervals, and the first end 111 is provided with a clamping hook 113; the first connecting end 123 of the pressing block 12 is hinged to the second end 112 of the supporting piece 11, so that the pressing block 12 can rotate relative to the supporting piece 11, so that the second connecting end 124 of the pressing block 12 is close to or away from the clamping hook 113. The pressing block 12 is defined as rotating relative to the supporting piece 11 to have a pressing position and an opening position, the distance between the second connecting end 124 and the clamping hook 113 when the pressing block 12 is in the pressing position is less than the distance between the second connecting end 124 and the clamping hook 113 when the pressing block 12 is in the opening position; when the pressing block 12 is in the pressing position, the pressing block 12 and the supporting piece 11 form an installation space 15 which can be used for clamping the laser head 32, when the pressing block 12 is in the opening position, the installation space 15 is open, and the laser head 32 can freely enter and exit the installation space 15. The second connecting end 124 of the pressing block 12 is provided with the buckling piece 13, the buckling piece 13 can be provided as a buckle, or a clamping hole or a reverse hook which can be buckled with the clamping hook 113 can be arranged on the buckling piece 13; the buckling piece 13 can be integrally formed with the pressing block 12, or the buckling piece 13 and the pressing block 12 can be arranged as a separate structure connected with each other, the buckling piece 13 can be fixed to the pressing block 12, or the buckling piece 13 can be movably arranged relative to the pressing block 12.

When the pressing block 12 rotates to the pressing position, the buckling piece 13 connected to the pressing block 12 can be buckled with the clamping hook 113 arranged on the supporting piece 11, so as to lock the pressing block 12 and the supporting piece 11, so that the laser head 32 can be clamped in the installation space 15, and the installation of the laser head 32 is realized. When the laser head 32 needs to be dismounted, only the buckling piece 13 is separated from the clamping hook 113, so that the pressing block 12 can rotate freely, so as to unlock the laser head 32. Therefore, when the clamping mechanism 1 is arranged in the laser processing equipment 100 for fixing the laser head 32, the laser head 32 is convenient to dismount.

[0053] Please refer to Figure 4 and Figure 5In an embodiment, the clamping member 13 is rotatable relative to the pressing block 12.

[0054] In the present embodiment, the clamping member 13 can be directly rotatably connected with the second connecting end 124 of the pressing block 12, or can be rotatably connected with the handle 14 as in the following embodiment. By rotatably arranging the clamping member 13 relative to the pressing block 12, the clamping member 13 can be clamped with or separated from the clamping hook 113 by only rotating the clamping member 13, without rotating the pressing block 12 simultaneously, so that the clamping member 13 is more flexible, and the clamping member 13 can be prevented from being excessively interfered by the pressing block 12 when the clamping member 13 is clamped with or separated from the clamping hook 113. In addition, when the laser head 32 is installed, the clamping member 13 can be first rotated to a suitable position, and then the pressing block 12 is pressed against the laser head 32, and then the clamping member 13 is clamped with the clamping hook 113.

[0055] Please refer to Figure 4 and Figure 5 In an embodiment, the clamping mechanism 1 further comprises a handle 14, one end of the handle 14 is hingedly connected with the second connecting end 124, and the hingedly connected position is a first hingedly connected position 141; the clamping member 13 is hingedly connected with the handle 14, and the hingedly connected position is a second hingedly connected position 142; the first hingedly connected position 141 and the second hingedly connected position 142 are eccentrically arranged; when the pressing block 12 is in the pressing position, the handle 14 has a locked state and an unlocked state relative to the pressing block 12; when the handle 14 is in the locked state, the clamping member 13 is clamped with the clamping hook 113; and when the handle 14 is in the unlocked state, the clamping member 13 is separated from the clamping hook 113.

[0056] In the present embodiment, the clamping mechanism 1 is provided with the handle 14 for driving the clamping member 13 to move, the handle 14 has a connecting end and an operating end which are arranged at intervals, the clamping member 13 is rotatably connected with the connecting end of the handle 14, and the connecting end of the handle 14 is hingedly connected with the second connecting end 124 of the pressing block 12; wherein the first hingedly connected position 141 at which the handle 14 is hingedly connected with the pressing block 12 is eccentrically arranged at the second hingedly connected position 142 at which the clamping member 13 is hingedly connected with the handle 14; a user can drive the handle 14 to rotate by pulling the operating end of the handle 14, so as to switch the handle 14 between the locked state and the unlocked state, and drive the handle 14 to move the clamping member 13, so as to drive the clamping member 13 to be clamped with or separated from the clamping hook 113 when the pressing block 12 is in the pressing position. In the case that the pressing block 12 is in the pressing position, when the handle 14 is rotated to the locked state, the clamping member 13 can be clamped with and locked by the clamping hook 113; and when the handle 14 is rotated to the unlocked state, the clamping member 13 is separated from the clamping hook 113. By this arrangement, the clamping member 13 can be clamped with or separated from the clamping hook 113 without directly operating the clamping member 13, and the operation arm is lengthened by the handle 14, so that the clamping member 13 can be clamped with or separated from the clamping hook 113 more conveniently, and the operation convenience is improved.

[0057] Optionally, in the embodiment, when the clasp 13 is engaged with the hook 113, the clasp end 131, the first hinge position 141 and the second hinge position 142 of the clasp 13 can be located on the same line, and the first hinge position 141 is located between the clasp end 131 and the second hinge position 142. Alternatively, the clasp end 131, the first hinge position 141 and the second hinge position 142 of the clasp 13 can not be located on the same line, for example, in the following embodiment, when the clasp 13 is engaged with the hook 113, the first line 144 between the clasp end 131 and the first hinge position 141 and the second line 145 between the clasp end 131 and the second hinge position 142 are not collinear, so as to improve the connection strength of the engagement between the clasp 13 and the hook 113, and improve the pressure of the pressure block 12 to the laser head 32.

[0058] Please refer to Figure 6 In an embodiment, when the clasp 13 is engaged with the hook 113 and the handle 14 is in the locked state, the line between the clasp end 131 and the first hinge position 141 of the clasp 13 is the first line 144, and the line between the clasp end 131 and the second hinge position 142 is the second line 145, and the second line 145 is located on the side of the first line 144 towards the mounting space 15.

[0059] In the embodiment, the handle 14, the clasp 13 and the pressure block 12 form a lever and eccentric wheel structure. Specifically, when the handle 14 is in the unlocked state, the handle 14 is in a relaxed state, and at this time the clasp 13 is separated from the hook 113. When the handle 14 is rotated from the unlocked state to the locked state, the clasp end 131 of the clasp 13 gradually approaches the hook 113, and the clasp end 131 will first overlap the hook 113. At this time, the handle 14 has not reached the locked position, and the handle 14 is continuously rotated. At this time, the first hinge position 141, which is the rotation center of the handle 14, is taken as the lever fulcrum, so as to make the second hinge position 142 and the clasp 13 rotate towards the side of the mounting space 15, so as to make the clasp 13 tightly engage the hook 113, so that the second line 145 between the clasp end 131 and the second hinge position 142 of the clasp 13 is located on the side of the first line 144 between the clasp end 131 and the first hinge position 141 towards the mounting space 15. At this time, the direction of the reaction force of the handle 14 from the locking member is not in the same direction as the tangent direction of the rotation center of the handle 14, and a self-locking structure is formed between the handle 14, the clasp 13, the hook 113 and the pressure block 12, so that the handle 14 is in a clamped and locked state, so as to ensure that the clasp 13 and the hook 113 are stably engaged and will not be loosened, and the laser head 32 clamping mechanism can stably clamp the laser head 32.

[0060] The operation end of the handle 14 and the second hinge position 142 are the manual force arm L1 when the handle 14 is locked, the first hinge position 141 and the second hinge position 142 are the force arm L2 when the clamping piece 13 is locked with the hook 113, the length of the handle 14 is extended, the force arm L1 of the handle 14 is greater than the self-locking force arm L2, so that the pressure required for manual operation is much smaller than the clamping force, and a smaller operating force can be used to lock the clamping mechanism 1 to reliably clamp the laser head 32, improving the operation convenience.

[0061] It should be noted that in the embodiment, the first connecting line 144 and the second connecting line 145 are not physical structures, and the included angle α of the first connecting line 144 and the second connecting line 145 can be 1°, 5°, 10°, 15°, 30° or any value greater than 0, which is not limited here.

[0062] Please refer to Figure 6 In an embodiment, the surface of the handle 14 facing the pressing block 12 is provided with an abutting portion 143, and the abutting portion 143 abuts against the pressing block 12 when the handle 14 is in the locked state. This arrangement allows the handle 14 and the pressing block 12 to interact in the pressing direction, and at this time, the component force of the force of the locking piece acting on the handle 14 is opposite to the direction of the force of the pressing block 12 acting on the handle 14, which is beneficial to locking the handle 14; and the pressure of the handle 14 on the pressing block 12 is also beneficial to clamping the laser head 32 by the pressing block 12, so that the clamping mechanism 1 can maintain a relatively stable clamping state, and the laser head 32 is reliably clamped.

[0063] Please refer to Figure 4 and Figure 7 In an embodiment, the surface of the support 11 facing the mounting space 15 is provided with a first positioning structure 114, and the first positioning structure 114 is used to cooperate with a second positioning structure 323 provided on the laser head 32 to position the laser head 32.

[0064] In the embodiment, the second positioning structure 323 and the first positioning structure 114 are mutually matched structures for positioning the laser head 32 when the laser head 32 is installed on the clamping mechanism 1. For example, the positioning column 1141 is arranged on the surface of the support 11 facing the installation space 15 as the first positioning structure 114, and the positioning hole 3231 is arranged on the side of the laser head 32 as the second positioning structure 323, and the positioning column 1141 is inserted into the positioning hole 3231 when the laser head 32 is installed. In some embodiments, the positioning column 1141 can be arranged on the laser head 32, and the corresponding positioning hole 3231 is arranged on the surface of the support 11 facing the installation space 15, and the laser head 32 can also be positioned in the same way. In some embodiments, the first positioning structure 114 can also include the positioning hole 3231 and the positioning column 1141, and the corresponding second positioning structure 323 includes the positioning hole 3231 and the positioning column 1141, the positioning hole 3231 in the first positioning structure 114 matches the positioning column 1141 in the second positioning structure 323, and the positioning column 1141 in the first positioning structure 114 matches the positioning hole 3231 in the second positioning structure 323. In addition, in some embodiments, the installation groove can also be arranged on the surface of the support 11 facing the installation space 15 as the first positioning structure 114, and part of the laser head 32 is embedded in the installation groove for positioning. Of course, the first positioning structure 114 and the second positioning structure 323 can also be other matched positioning structures, such as bosses and grooves.

[0065] In the embodiment, one first positioning structure 114 and one second positioning structure 323 are matched as a group of positioning structures, and only one group of positioning structures can be arranged between the support 11 and the laser head 32, or two or more groups of positioning structures can be arranged, which is not limited herein.

[0066] Please refer to Figure 4 and Figure 7 In an embodiment, the first positioning structure 114 is arranged as one of the positioning column 1141 and the positioning hole 3231, the second positioning structure 323 is arranged as the other one of the positioning column 1141 and the positioning hole 3231, and the positioning column 1141 is inserted into the positioning hole 3231.

[0067] In the embodiment, the support 11 can be provided with a positioning column 1141 as a first positioning structure 114 on the surface thereof facing the mounting space 15, and a positioning hole 3231 as a second positioning structure 323 can be arranged on the side surface of the laser head 32. In some embodiments, the positioning column 1141 can be arranged on the laser head 32, and a positioning hole 3231 can be arranged on the surface of the support 11 facing the mounting space 15.
