In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skill in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0052] The laser processing equipment is a processing equipment using laser as a processing medium to achieve the processing purposes of laser cutting, laser welding, laser marking, laser engraving, etc.

[0053] In related technologies, in order to perform laser processing on workpieces with large thickness or height, a riser is usually set up to elevate the laser processing device. However, in order to prevent the laser from penetrating the base plate of the riser, the laser focus needs to be a certain distance from the base plate of the riser, which means that the riser needs to be set higher. This will increase the size of the riser, making it inconvenient to move and transport, and requiring a large storage space.

[0054] To address the aforementioned problems, this utility model proposes a laser equipment elevation bracket 100. This laser equipment elevation bracket 100 can be applied to laser processing equipment, which also includes a laser processing device. The laser equipment elevation bracket 100 can be used to elevate the laser processing device. The laser processing device typically includes a frame and a laser head. The frame has a processing space, which can accommodate a detachable material platform 2. The processing space has a bottom opening 21, which is exposed when the material platform 2 is removed. The laser head is positioned within the processing space, facing the bottom opening 21. The laser head emits laser light to perform laser cutting, laser welding, laser marking, and laser engraving on the workpiece. The laser equipment elevation frame 100 forms an extended space with a top opening 21. When using the laser equipment elevation frame 100 to elevate the laser processing device, the material loading platform 2 and other structures mounted on the frame of the laser processing device are removed. The bottom opening 21 of the laser processing device is connected to the top opening 21 of the laser equipment elevation frame 100. This arrangement increases the height of the space below the laser head, allowing the workpiece to be placed at least partially in the extended space of the laser equipment elevation frame 100, and the laser emitted from the laser head can also enter the extended space of the laser equipment elevation frame 100.

[0055] See also Figures 1 to 3 In one embodiment of this utility model, the laser equipment elevation frame 100 includes a base 1, a platform 2, and a lifting assembly 3. The platform 2 is located above the base 1 and has an opening 21 opposite to the base 1. The lifting assembly 3 is located between the base 1 and the platform 2. The lifting assembly 3 includes at least one driving member 32 and two telescopic mechanisms 31 located on both sides of the opening 21 along the first direction X. The telescopic mechanisms 31 are connected to the base 1 and the platform 2. The driving member 32 is connected to the telescopic mechanism 31 for driving the telescopic mechanism 31 to extend and retract along the height direction Z, so as to drive the platform 2 to rise and fall relative to the base 1.

[0056] In the embodiment of the present application, the laser equipment heightening stand 100 comprises a base 1, a platform 2, and a lifting assembly 3 for connecting the base 1 and the platform 2.

The projection of the lifting assembly 3 and the opening 21 of the platform 2 on the base 1 is arranged in a staggered manner, i.e., the platform 2 is located outside the opening 21. The lifting assembly 3 comprises a driving member 32 and two telescopic mechanisms 31. The telescopic mechanism 31 can be telescoped along the height direction Z of the laser equipment heightening stand 100. Two telescopic mechanisms 31 are arranged in a spaced manner along the first direction X, and are respectively located on both sides of the opening 21. One end of the telescopic mechanism 31 is connected with the base 1, and the other end of the telescopic mechanism 31 is connected with the platform 2 to support the platform 2. The arrangement of the two telescopic mechanisms 31 can stably support the platform 2. Optionally, the lifting assembly 3 can also be provided with the telescopic mechanism 31 on the other side of the opening 21.

[0058] The driving member 32 is in transmission connection with the telescopic mechanism 31, and is used for driving the telescopic mechanism 31 to telescope, so as to drive the platform 2 to ascend or descend relative to the base 1, so that the laser equipment heightening stand 100 has an unfolded state and a folded state. The height of the platform 2 in the unfolded state of the laser equipment heightening stand 100 is higher than the height of the platform 2 in the folded state of the laser equipment heightening stand 100. When the laser equipment heightening stand 100 is in the unfolded state, the lifting assembly 3, the base 1, and the platform 2 enclose an expansion space which is in communication with the opening 21 of the platform 2. Optionally, the unfolded state of the laser equipment heightening stand 100 can have multiple states. The platform 2 is lifted to different height positions by the lifting assembly 3 to form different unfolded states.

[0059] Optionally, the telescopic mechanism 31 can be a scissor-type telescopic mechanism 31, comprising a first connecting arm 313 and a second connecting arm 314, one end of the first connecting arm 313 and one end of the second connecting arm 314 are hinged to each other, one end of the first connecting arm 313 away from the second connecting arm 314 is hinged to the base 1, and one end of the second connecting arm 314 away from the first connecting arm 313 is hinged to the platform 2; the driving member 32 is used to drive the first connecting arm 313 and the second connecting arm 314 to fold or unfold along the height direction Z; for example, a screw rod 311 and a first connecting piece 312 threaded on the screw rod 311 can be arranged as in the following embodiment, the first connecting arm 313 and the second connecting arm 314 are both hinged to the first connecting piece 312, the driving member 32 drives the screw rod 311 to rotate to make the first connecting piece 312 move along the length direction of the screw rod 311, so as to make the first connecting arm 313 and the second connecting arm 314 fold or unfold. In some embodiments, the telescopic mechanism 31 can also not be provided with the first connecting arm 313, the screw rod 311 is arranged on the base 1, the driving member 32 drives the first connecting piece 312 to move, the angle between the second connecting arm 314 and the screw rod 311 changes, and the second connecting arm 314 folds or unfolds relative to the screw rod 311, which can also drive the platform 2 to ascend and descend. In addition, the lifting assembly 3 can be a cylinder pushing mechanism or the like. Optionally, the driving member 32 can be an electric structure, a pneumatic structure or a structure that can be manually driven by a user, which is not limited here.

[0060] That is, the technical scheme of the utility model, by setting the laser equipment heightening frame 100 as a telescopic structure, the platform 2 is driven to ascend and descend relative to the base 1 by the lifting assembly 3, so that the height of the laser equipment heightening frame 100 can be adjusted. When the laser equipment heightening frame 100 is needed to be used to pad the laser processing device, the platform 2 is lifted to the required height by the lifting assembly 3, and the surrounding fence 5 is covered. When the laser equipment heightening frame 100 is not needed to be used, the surrounding fence 5 is removed, and then the platform 2 is driven to descend by the lifting assembly 3 to reduce the height and volume of the laser equipment heightening frame 100, so as to move and transport, and reduce the storage space of the laser equipment heightening frame 100.

[0061] Please refer to Figure 2 and Figure 3In an embodiment, the telescopic mechanism 31 comprises a screw rod 311, a first connecting member 312, a first connecting arm 313 and a second connecting arm 314. The screw rod 311 extends along a second direction Y, the second direction Y, the first direction X and the height direction Z are perpendicular to each other. The first connecting member 312 is threadedly connected to the screw rod 311. One end of the first connecting arm 313 is hingedly connected to the first connecting member 312, and the other end of the first connecting arm 313 is hingedly connected to the base 1. One end of the second connecting arm 314 is hingedly connected to the first connecting member 312, and the other end of the second connecting arm 314 is hingedly connected to the platform 2. The driving member 32 is drivingly connected to the screw rod 311, for driving the screw rod 311 to rotate, so as to drive the first connecting member 312 to move along the length direction of the screw rod 311, so as to fold or unfold the first connecting arm 313 and the second connecting arm 314 relative to the screw rod 311.

[0062] In the embodiment, the telescopic mechanism 31 is provided as a scissor structure, comprising the screw rod 311 and the first connecting member 312 which is a screw rod nut threadedly cooperating with the screw rod 311. The telescopic mechanism 31 further comprises the first connecting arm 313 arranged above the screw rod 311 and the second connecting arm 314 arranged below the screw rod 311. The two ends of the first connecting arm 313 are hingedly connected to the first connecting member 312 and the base 1 respectively, and the two ends of the second connecting arm 314 are hingedly connected to the first connecting member 312 and the platform 2 respectively. Moreover, along the second direction Y (i.e. the length direction of the screw rod 311), the first connecting arm 313 and the second connecting arm 314 are located on the same side of the first connecting member 312. In this way, when the driving member 32 drives the screw rod 311 to rotate, the first connecting member 312 moves along the second direction Y, thereby driving the first connecting arm 313 and the second connecting arm 314 to move, so as to fold or unfold the first connecting arm 313 and the second connecting arm 314 relative to the screw rod 311. In this way, the first connecting arm 313 and the second connecting arm 314 can be folded, so as to sufficiently reduce the height and volume of the laser equipment heightening stand 100 in the folded state.

[0063] Optionally, the driving member 32 can be provided as a motor, for driving the screw rod 311 to rotate by electric driving. In some embodiments, the driving member 32 can also be provided as a crank 321, for driving the screw rod 311 to rotate by manually rotating the crank 321. In the embodiment, even by manual driving, the telescopic mechanism 31 is relatively labor-saving.

[0064] Please refer to Figure 2In an embodiment, the lead screw 311 comprises a first section 3111 and a second section 3112 arranged along the second direction Y, the first section 3111 and the second section 3112 have opposite thread directions, the telescopic mechanism 31 comprises two first connecting members 312, one of the first connecting members 312 is threadedly connected to the first section 3111, and the other first connecting member 312 is threadedly connected to the second section 3112; the telescopic mechanism 31 comprises two first connecting arms 313 and two second connecting arms 314, one first connecting arm 313 and one second connecting arm 314 are connected to one first connecting member 312.

In this way, when the driving member 32 drives the lead screw 311 to rotate, the two first connecting members 312 move towards or away from each other, so that the two first connecting arms 313 and the two second connecting arms 314 can be synchronously stretched or folded. Through the arrangement of the two sets of first connecting arms 313 and second connecting arms 314, the support strength and stability of the platform 2 can be improved.

[0066] Please refer to Figure 2 and Figure 3 In an embodiment, the telescopic mechanism 31 further comprises a limiting member 318, the limiting member 318 is fixed between the first section 3111 and the second section 3112, and at least one first connecting member 312 abuts against the limiting member 318 when the laser equipment heightening stand 100 is in the folded state.

[0067] In the embodiment, the limiting member 318 can be provided as a limiting protrusion fixed on the lead screw 311, or as a limiting ring sleeved on the lead screw 311. Through the arrangement of the limiting member 318, the movement range of the first connecting member 312 can be limited. When the laser equipment heightening stand 100 is folded, the first connecting member 312 gradually approaches the limiting member 318 until abutting against the limiting member 318, at this time, the first connecting member 312 cannot continue to move, and the telescopic mechanism 31 cannot continue to fold, thereby limiting the descending height of the platform 2, which can avoid the collision between the platform 2 and the base 1, and improve the use safety.

[0068] Please refer to Figure 2 and Figure 3In one embodiment, the telescopic mechanism 31 further includes a second connecting member 317, a third connecting arm 315, and a fourth connecting arm 316.

[0069] In this embodiment, a second connecting member 317 is provided at the end of the lead screw 311. The second connecting member 317 can be sleeved on the lead screw 311 or spaced apart from the lead screw 311. The lead screw 311 can rotate relative to the second connecting member 317. The telescopic mechanism 31 also includes a third connecting arm 315 and a fourth connecting arm 316. The two ends of the third connecting arm 315 are respectively hinged to the second connecting member 317 and the first connecting arm 313, and the hinge position between the third connecting arm 315 and the first connecting arm 313 is located between the two ends of the first connecting arm 313. The two ends of the fourth connecting arm 316 are respectively hinged to the second connecting member 317 and the second connecting arm 314, and the hinge position between the fourth connecting arm 316 and the second connecting arm 314 is located between the two ends of the second connecting arm 314. This arrangement can improve the structural stability and support strength of the telescopic mechanism 31, avoid bending deformation of the first connecting arm 313 and the second connecting arm 314, and help increase the load-bearing capacity.

[0070] Please see Figure 2 and Figure 3 In one embodiment, the drive element 32 is configured as a rocker arm 321.

[0071] In this configuration, when it is necessary to switch between the unfolded and folded states of the laser equipment elevation frame 100, the crank 321 is turned to drive the lead screw 311 to rotate, thereby extending and retracting the telescopic mechanism 31.
