Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving machines, in particular to a fixing frame for a laser tube of a laser engraving machine. Background Art

[0002] Most existing laser tube brackets use two semicircular rings of the same diameter to hold and support the laser tube, depending on the tube diameter. Laser tubes of different diameters require rigid brackets with upper and lower semicircular rings of the same diameter, making replacement and use inconvenient.

[0003] In the prior art, a Chinese patent document with publication number CN218476154U has been proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a fixing frame for a laser tube of a laser engraving machine includes a circular frame, and two lower brackets and an adjustment device for moving the lower brackets are provided on the bottom surface of the circular frame.

[0004] In order to solve the problem that laser tubes with different diameters need to use rigid brackets with upper and lower semicircular rings of the same diameter, which is inconvenient to replace and use, the existing technology adopts an adjustable fixing bracket for fixing. However, the clamping of the fixing bracket still needs to be manually adjusted, which leads to slow manual clamping efficiency and the problem of clamping being too tight or too loose. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing bracket for a laser tube of a laser engraving machine, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A fixing frame for a laser tube of a laser engraving machine comprises a fixing frame, a supporting device is movably mounted on the bottom of the fixing frame, a pressing device is fixedly mounted on the top of the fixing frame, and a fixing component is fixedly mounted on the surface of the pressing device;

[0008] The fixing assembly includes a telescopic rod, one end of the telescopic rod is fixedly mounted with a fixing plate, and a spring is fixedly mounted on the surface of the fixing plate.

[0009] A further improvement of the technical solution of the present utility model is that: the fixing frame includes a fixing frame outer frame, the inner surface of the fixing frame outer frame is provided with a movable groove, and the top surface of the fixing frame outer frame is provided with a movable hole.

[0010] A further improvement of the technical solution of the present utility model is that: the supporting device includes a servo motor fixedly mounted on one side of the outer frame of the fixed frame, the output end of the servo motor is fixedly mounted with a bidirectional threaded rod, the surface of the bidirectional threaded rod is movably mounted with a movable block, the top surface of the movable block is fixedly mounted with a supporting plate, and by arranging a servo motor to connect the bidirectional threaded rod, the position of the supporting plate can be mechanically driven by the motor to adjust the position of the supporting plate, thereby preventing manual adjustment from causing inaccurate supporting position, thereby causing unbalanced placement of the pipeline, and further affecting the cooperation and fixation of the fixed plate.

[0011] A further improvement of the technical solution of the present utility model is that: the pressing device includes a hydraulic cylinder fixedly installed on the top surface of the outer frame of the fixing frame, the control end of the hydraulic cylinder is fixedly installed with a pressing rod, and one end of the pressing rod is fixedly installed with a mounting plate. By setting the pressing device, it is possible to facilitate the installation of the fixing component while starting the hydraulic cylinder to mechanically drive the pressing rod to drive the fixing component to move downward, thereby cooperating with the supporting device to perform the pipeline fixing operation, effectively improving the mechanization degree of the fixing frame.

[0012] A further improvement of the technical solution of the present invention is that: the telescopic rod is fixedly mounted on the surface of the mounting plate, and a connecting elastic band is fixedly mounted on one side of the fixing plate. By arranging the telescopic rod and the spring between the mounting plate and the fixing plate, a buffer damping structure can be formed, so that a certain buffer can be provided during clamping to prevent direct downward pressing and fixing from easily squeezing too much and causing damage to the pipeline. At the same time, the buffering amplitude is limited and does not hinder fixation.

[0013] A further improvement of the technical solution of the present utility model is that: the bidirectional threaded rod is arranged in the movable groove and is slidably connected to the inner surface of the outer frame of the fixed frame, and the lower pressure rod is slidably connected to the outer frame of the fixed frame through the movable hole. By installing the bidirectional threaded rod in the movable groove, it is possible to drive the movable block to move while limiting it.

[0014] A further improvement of the technical solution of the present invention is that the top end of the spring is fixedly connected to the top surface of the mounting plate, and one end of the connecting elastic band is fixedly connected to one side of another set of fixing plates.

[0015] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0016] 1. The utility model provides a fixing bracket for laser tubes of laser engraving machines. By setting a servo motor connected to a bidirectional threaded rod, the motor can mechanically drive the adjustment of the position of the supporting plate, preventing manual adjustment from causing inaccurate supporting position, resulting in unbalanced placement of the pipeline, and further affecting the fixation of the fixing plate.

[0017] 2. The utility model provides a fixing bracket for the laser tube of a laser engraving machine. By setting a downward pressing device, it is easy to install the fixing component. At the same time, the hydraulic cylinder can be started to mechanically drive the downward pressing rod to drive the fixing component to move downward, thereby cooperating with the supporting device to perform the pipeline fixing operation, effectively improving the mechanization degree of the fixing bracket.

[0018] 3. The utility model provides a fixing bracket for the laser tube of a laser engraving machine. By arranging a telescopic rod and a spring between the mounting plate and the fixing plate, a buffer damping structure can be formed, so that a certain buffer can be provided during clamping to prevent direct downward pressure and fixing, which may cause excessive squeezing and damage to the tube. At the same time, the buffering amplitude is limited and does not hinder fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1-5 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the supporting device 2 includes a servo motor 21 fixedly mounted on one side of the outer frame 11 of the fixed frame, the output end of the servo motor 21 is fixedly mounted with a bidirectional threaded rod 22, the surface of the bidirectional threaded rod 22 is movably mounted with a movable block 23, and the top surface of the movable block 23 is fixedly mounted with a supporting plate 24. By arranging the servo motor 21 to connect the bidirectional threaded rod 22, the position of the supporting plate 24 can be mechanically driven by the motor to prevent manual adjustment from causing inaccurate supporting position, thereby causing unbalanced placement of the pipeline, and further affecting the fixation of the fixed plate 42. The pressing device 3 includes a hydraulic cylinder 31 fixedly installed on the top surface of the fixing frame outer frame 11, a pressing rod 32 is fixedly installed on the control end of the hydraulic cylinder 31, and a mounting plate 33 is fixedly installed on one end of the pressing rod 32.
