[0002] Existing double-folded or multi-folded laser tubes are generally installed on laser equipment through supporting devices. Laser equipment has high requirements for precision, especially after the angle and position of the laser tube are debugged, slight changes in angle will cause a large change in the route of the laser, thus affecting the accuracy and efficiency of laser processing. At present, the laser tube generally uses two supporting devices to support it front and back to fix it in the laser equipment platform. The laser equipment platform will generate a high temperature during operation. The temperature change can easily cause slight deformation of part of the workpiece or the entire platform of the laser equipment platform. Due to the large span of the laser tube, slight deformation of part of the workpiece or the entire platform of the laser equipment platform will also act on the supporting device, causing the angle of the laser tube to shift, thereby affecting the processing accuracy. Summary of the invention

[0005] Furthermore, a through slot is provided on the mounting seat, the slideway extends along a through direction of the through slot, and a shell is sleeved on the outer side of the mounting seat to support one end of the elastic member.

[0006] Furthermore, the deformation absorbing component also includes a disc seat arranged below the mounting seat, the disc seat is connected to the base through bolts, and the mounting seat and the disc seat are rotatably connected with the extension rod of the ball head as a rotating shaft.

[0007] Furthermore, the extension rod of the ball head passes through the disc seat to be fixedly connected to the base.

[0010] Beneficial effects: This solution absorbs the micro deformation transmitted from the laser device to the base by providing a support device with a deformation absorption component. Specifically, a ball head that can rotate in the mounting seat is provided so that it can be adjusted to rotate 360° when the base receives local distortion and deformation.

DETAILED DESCRIPTION

[0012] Combination Figures 1 to 6 As shown, this embodiment provides a laser device 1, including a mounting platform 2, a laser tube 3, a fixed support structure and at least one multi-dimensional adaptive support device 4, wherein the fixed support structure and the support device 4 are used to support and fix the laser tube 3 on the mounting platform 2 of the laser device 1.

[0013] Combination Figures 3 to 6 As shown, the posture-stable laser tube support device 4 comprises a base 41, a deformation absorbing component 42, and a fixing component 43, wherein the deformation absorbing component 42 is rotatably connected to the base 41, and comprises a ball head 422, a mounting seat 424, and an elastic member 426, wherein the ball head 422 is connected to the base 41 via an extension rod 423; the mounting seat 424 is connected to the fixing component 43 via a connecting member 44, and a slideway 425 extending along the length direction of the laser tube 3 is formed in the mounting seat 424; the ball head 422 is rotatably arranged in the slideway 425 to absorb the torque transmitted by the base 41, and the elastic members 426 are respectively arranged on opposite sides of the ball head 422 along the extension direction of the slideway 425 to absorb the deformation along the length direction of the laser tube 3 transmitted from the base 41 to the fixing component 43.

[0014] The torque referred to here refers to the rotational torque force applied to the base when the mounting platform undergoes a slight deformation in a certain direction. The deformation along the length direction of the laser tube refers to the force on the base along the length direction of the laser tube caused by the extension, contraction or local deformation of the mounting platform due to temperature, or caused by installation errors.

[0015] Combination Figures 4 to 6 As shown, in this embodiment, the base 41 is provided with a mounting hole suitable for being connected to the mounting platform 2 of the laser device 1 by bolts, and a bolt hole is provided in the middle position of the base 41 for connecting the disc seat 421. The fixing component 43 is set to a polygon, which is connected to the deformation absorbing component 42 through a connecting member 44, and the fixing component 43 can adopt an existing structure. In one embodiment, the fixing component 43 includes an upper support frame 431 and a lower support frame 432, and the upper support frame 431 and the lower support frame 432 are connected by sheet metal. The upper support frame 431 and the lower support frame 432 are suitable for enclosing a space for supporting and fixing two laser tubes 3, and a triangular support member is provided between the two laser tubes 3 to support the two laser tubes 3 to prevent the laser tube 3 from shaking in the space enclosed by the fixing component 43.

[0016] Combination Figures 4 to 6As shown, the deformation absorbing assembly 42 includes a disc seat 421, a mounting seat 424, a ball head 422, an elastic member 426 and a housing 427. The disc seat 421 is connected to the base 41, the mounting seat 424 is arranged above the disc seat 421, a slot for mounting the ball head 422 is arranged at the central axis of the mounting seat 424, and a through slot extending along the length direction of the laser tube 3 is arranged in the mounting seat 424. A slideway 425 is formed in the through groove, and the cross-section of the through groove is set to be hemispherical or fan-shaped suitable for matching the size of the ball head 422. The ball head 422 is set in the slideway 425 and can rotate 360° in the slideway 425. The extension rod 423 of the ball head 422 extends downward to be connected to the base 41 and can be fixedly connected to the base 41, so that when the base 41 is subjected to a local rotation torque, the ball head 422 can be driven to rotate in the slideway 425 to absorb the torque exerted on the base 41, prevent the torque and deformation from being transmitted to the fixing component 43, and keep the laser tube 3 in the fixing component 43 stable.

[0017] Two elastic members 426 are also arranged in the slideway 425. The two elastic members 426 are respectively arranged at opposite ends of the ball head 422 and extend along the length direction of the slideway 425, so that when the base 41 is deformed along the length direction of the laser tube 3, the ball head 422 can be driven to compress the elastic member 426, so that the deformation borne by the base 41 is absorbed by the ball head 422, thereby preventing the deformation from being transmitted to the laser tube 3 of the fixing assembly 43. Here, a housing 427 is sleeved on the outer side of the mounting seat 424 to support one end of the elastic member 426 and restrict the elastic member 426 in the slideway 425. The elastic member 426 can be set as a spring.

[0018] Combination Figures 4 to 6 As shown, in this embodiment, the mounting seat 424 and the disc seat 421 are connected with the extension rod 423 of the ball head 422 as the rotation axis to realize rotation connection, and the extension rod 423 is used to keep the mounting seat 424 in a predetermined position, and can only rotate around the extension rod 423. When the base 41 is subjected to local torsional deformation, the ball head 422 rotates in the slide 425 to absorb the torque. When the base 41 is subjected to deformation force along the length direction of the laser tube 3, the ball head 422 moves along the direction of the slide 425 to compress one of the elastic members 426, thereby absorbing the deformation. It should be noted that during the operation of the support device 4, the deformation caused by the temperature is mainly concentrated along the length direction of the laser tube 3 and the rotation torque. Therefore, this solution can effectively deal with the influence of the deformation caused by the temperature of the laser device 1 during the operation on the laser tube 3.

[0019] The laser device 1 is provided with a fixed support structure and a support device 4, which are respectively arranged near the front and rear ends of the laser tube 3 and have a large span. When a slight deformation occurs, the fixed support structure plays a stabilizing role, and the slight deformation is absorbed by the deformation absorption component of the support device 4. The difference between the fixed support structure and the support device 4 here is mainly that the base of the fixed support structure is rigidly connected to the fixed component to prevent the fixed component from rotating, thereby playing a fixing role.

[0020] Through the solution of this embodiment, the stability of the double-folded laser tube 3 can be effectively improved, and the ability to resist slight deformation can be improved to improve the accuracy of the laser during operation.

[0021] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.

[0022] The above description of the drawings used in the implementation manner only illustrates certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without paying creative work.
