Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile cutting, in particular to an automatic laser cutting machine for aluminum profiles. Background Art

[0002] Aluminum profile is a special metal material made of aluminum alloy through extrusion or rolling. It has the characteristics of light weight, corrosion resistance, good thermal conductivity, etc., and is widely used in construction, automobiles, radiators and other fields. In practical applications, the length and shape of aluminum profiles can be customized according to actual needs, and cut into sections to meet the needs of specific projects.

[0003] However, traditional aluminum profile cutting methods, such as mechanical sawing or manual cutting, are usually limited by the accuracy of the saw blade or tool and the operator's skill level. The cutting accuracy is not high and secondary trimming is required after cutting, resulting in a relatively slow cutting speed. Especially when dealing with thicker or harder aluminum profiles, it often takes longer to complete the cutting task. Utility Model Content

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 5 , which is an automatic laser cutting machine for aluminum profiles according to an embodiment of the utility model, includes an operating table 10, a laser cutting assembly 20 installed at one end of the operating table 10, and three clamping assemblies 30 installed at intervals on the operating table 10; wherein, one clamping assembly 30 is fixedly installed at one end of the operating table 10, and the other two clamping assemblies 30 can be slidably connected to the operating table 10.

[0030] Guide rails 11 are installed on opposite sides of the top surface of the operating table 10 , and racks 12 are installed on the inner wall of the operating table 10 at one side corresponding to each guide rail 11 ; the guide rails 11 and the racks 12 are used to match and slide to connect the two clamping components 30 .

[0031] In this embodiment, the guide rail 11 is disposed along the length direction of the operating platform 10 , and the rack 12 is disposed along the length direction of the operating platform 10 .

[0032] The laser cutting assembly 20 includes a gantry 21 connected to one end of the operating table 10 , a support frame 22 slidably connected to the top of the gantry 21 , and a fiber laser 23 installed on one side of the support frame 22 ; the emission port of the fiber laser 23 is arranged toward the operating table 10 .

[0033] like Figure 2 As shown, in this embodiment, the support frame 22 is slidably connected to the gantry 21 via a guide rail pair, and the movement direction of the support frame 22 is perpendicular to the length direction of the operating platform 10 .

[0034] The clamping assembly 30 includes a bottom plate 31, an annular plate 32 mounted on the top surface of the bottom plate 31, four hand-adjustable slides 33 evenly spaced and mounted on one side of the annular plate 32, and four contact rollers 34 respectively mounted on one end of each hand-adjustable slide 33; the contact rollers 34 are arranged along the radial direction of the annular plate 32. The center hole of the annular plate 32 is used for the aluminum profile to pass through, and the contact rollers 34 are used to abut against the aluminum profile. The clamping assembly 30 is used to position the aluminum profile from different positions, and the fiber laser 23 on the gantry 21 emits laser to cut the aluminum profile, which can achieve high-precision cutting and automated operation, greatly improving the flexibility and efficiency of production.

[0035] Specifically, the contact rollers 34 are arranged in pairs, and the two contact rollers 34 of the same pair are arranged facing each other. The length direction of one pair of contact rollers 34 is perpendicular to the length direction of the other pair of contact rollers 34.

[0036] Furthermore, if Figure 3 and Figure 4 As shown, the plane where one pair of contact rollers 34 is located is offset from the plane where the other pair of contact rollers 34 is located, that is, the two pairs of contact rollers 34 are not on the same plane. By adjusting the manual slide 33, the two pairs of contact rollers 34 can be adjusted independently of each other to adapt to aluminum profiles of different widths and thicknesses.

[0037] In this embodiment, the bottom plate 31 of one clamping assembly 30 is fixedly connected to one end of the operating table 10, and the bottom plates 31 of the other two clamping assemblies 30 are slidably connected to the operating table 10. Specifically, the bottom surfaces of the bottom plates 31 of the other two clamping assemblies 30 are connected with sliders 311 and gears 312 at opposite ends, respectively, the gears 312 are located on the inner side of the sliders 311, the sliders 311 are matched and connected with the guide rails 11, and the gears 312 are matched and meshed with the racks 12 one by one, so as to realize the sliding connection between the two clamping assemblies 30 and the operating table 10. In actual use, the friction between the gears 312 and the racks 12 can generate a certain resistance by utilizing the interaction between them, and this resistance can be regarded as the damping of sliding. This damping can slow down the relative movement between the sliders 311 and the guide rails 11, help prevent easy sliding and excessive vibration, and thus improve the stability and accuracy of the clamping to a certain extent.

[0038] The above-mentioned automatic laser cutting machine for aluminum profiles has a simple structure and is easy to use. The clamping assembly 30 is used to position the aluminum profile, and the fiber laser 23 on the gantry 21 emits laser to cut the aluminum profile, which can achieve high-precision cutting and automated operation, greatly improving the flexibility and efficiency of production.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
