Description

Technical Field

[0001] The utility model belongs to the field of metal fitting processing, and particularly relates to a laser cutting machine for metal fitting processing. Background Technique

[0002] A laser cutting machine for metal fitting processing is a device that uses a highly energetic and concentrated laser beam to cut and process metal materials. It usually consists of a laser generator, an optical system, and a mechanical system, and can precisely cut metal materials, including steel, aluminum alloy, copper, etc.; the working principle of the laser cutting machine is to use the laser beam to melt and vaporize the metal material, thereby realizing cutting. After the laser beam is focused by the optical system, a light spot with a high energy density can be generated, causing the local melting and evaporation of the metal material, thereby realizing precise cutting.

[0003] At present, most of the laser cutting machines applied to metal fittings use special fixed molds to fix the metal fittings therein. When the size of the metal fittings to be cut changes, only by replacing the fixed molds can the metal fittings be fixed. This method not only requires a large number of prefabricated fixed molds, resulting in an increase in usage costs, but also when the size of the metal fittings is large, it is difficult for the fixed molds to limit the metal fittings well, resulting in inaccurate laser cutting of the metal fittings. At the same time, in a cost-effective factory, it will affect a certain production efficiency, and the existing laser cutting table for metal fittings lacks efficient heat dissipation for the tabletop and metal fittings. Prolonged high-temperature operation may cause thermal expansion of the tabletop and metal fittings, and then cause dimensional changes and shape deformations of the equipment and metal fittings, affecting the processing accuracy; therefore, a laser cutting machine for metal fitting processing is proposed to solve the problems of traditional metal fitting processing.

[0008] An installation cross beam is commonly installed between the two mounting seats meshed with the same thread flank in the two sets of metal fitting positioning components. A number of positioning bolts are arranged along the transverse direction of the installation cross beam.

[0010] As a further improvement of the present utility model, each of the two sets of metal fitting positioning components further includes a reciprocating motor arranged on the upper end face of the frame. The output end of the reciprocating motor is connected to one end of the threaded lead screw.

[0011] As a further improvement of the present utility model, a deep groove ball bearing part is also assembled in the bearing seat. The other end of the threaded lead screw is in full cooperation with the deep groove ball bearing part; a sleeve is sleeved at the bottom of each positioning bolt.

[0012] As a further improvement of the present utility model, the adjustment seat is arranged in a U shape and light bearings are assembled at both ends thereof.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] Given by Figures 1 - 3 There is a laser cutting machine for metal fitting processing, including a frame 1;

[0024] On the upper end surface of the frame 1, a cutting table surface is formed, and two groups of metal fitting positioning components 3 and a group of high-efficiency heat dissipation components 4 are assembled and arranged on the cutting table surface; among them

[0025] Both groups of metal fitting positioning components 3 include bearing seats 31 arranged on the upper end surface of the frame 1. A threaded lead screw 34 is rotatably provided on the bearing seat 31. Two nut sleeves 35 are externally meshed with the threaded lead screw 34. The two nut sleeves 35 are respectively meshed with one tooth line of the threaded lead screw 34. Mounting seats 36 are installed outside the two nut sleeves 35;

[0026] Between the two mounting seats 36 meshed with the same tooth line in the two groups of metal fitting positioning components 3, a mounting cross beam 37 is commonly installed. A plurality of positioning bolts 38 are arranged along the transverse direction on the mounting cross beam 37;

[0027] The high-efficiency heat dissipation component 4 includes two positioning seats 41 arranged on the upper end surface of the frame 1. An adjusting seat 42 is carried on the upper end surfaces of the two positioning seats 41. A small lead screw 44 is rotatably provided between the adjusting seats 42. A slider seat 45 is externally meshed with the small lead screw 44. A high-efficiency heat dissipation fan 48 is installed on one side of the slider seat 45.

[0028] In this embodiment, through the mutual movement and cooperation of multiple components in the metal fitting positioning component 3, in actual use, the set metal fitting positioning component 3 can drive the two mounting cross beams 37 to freely adjust the spacing above the frame 1, so as to cooperate with the plurality of positioning bolts 38 arranged on the mounting cross beam 37 to complete the stable downward pressing and limiting of the metal fitting; compared with the traditional mold limiting, when the three-axis laser cutting machine body 2 of the present application cuts the metal fitting, through the limiting of the metal fitting by the metal fitting positioning component 3, it can ensure that the metal fitting is stably clamped during the processing, thereby ensuring the processing accuracy and stability. At the same time, the set mounting cross beam 37 can also freely adjust the clamping spacing for metal fittings of different sizes, so as to use the positioning bolts 38 to press and limit metal fittings of different sizes, improving the processing efficiency and the universality of the limiting.

[0029] Furthermore, through the mutual movement and cooperation of multiple components within the efficient heat dissipation assembly 4, during actual use, the efficient heat dissipation assembly 4 can drive the efficient heat dissipation fan 48 to perform reciprocating linear movement above the frame 1. By controlling the lateral movement of the efficient heat dissipation fan 48 through the efficient heat dissipation assembly 4, it can ensure that the efficient heat dissipation fan 48 evenly covers the metal fittings and the cutting tabletop, thereby achieving a uniform heat dissipation effect for the metal fittings. At the same time, the reciprocating mobile efficient heat dissipation can reduce the temperature of the metal fittings and the cutting tabletop, reducing the thermal deformation of the metal fittings caused by high temperature, which helps to maintain the cutting quality and processing accuracy.

[0030] Specifically, referring to Figure 2 , both sets of metal fitting positioning components 3 further include a reciprocating motor 33 disposed on the upper end surface of the frame 1, and the output end of the reciprocating motor 33 is connected to one end of the threaded lead screw 34.

[0031] In this embodiment, during use, the provided reciprocating motor 33 can be used to rotate and drive the threaded lead screw 34. When the user connects the power supply to the reciprocating motors 33 within the two sets of metal fitting positioning components 3, the reciprocating motor 33 can drive its output end, thereby causing the threaded lead screw 34 to rotate.

[0032] During use, the power connection method of the provided reciprocating motor 33 is prior art, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the art. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0033] Specifically, referring to Figure 2 , a deep groove ball bearing part 32 is also assembled in the bearing seat 31, and the other end of the threaded lead screw 34 is in full contact and cooperation with the deep groove ball bearing part 32; a 39 is sleeved at the bottom of each positioning bolt 38.

[0034] In this embodiment, the provided deep groove ball bearing part 32 can be used to cooperate with the threaded lead screw 34 to achieve the stable rotation of the threaded lead screw 34. In a preferred embodiment, the provided deep groove ball bearing part 32 can reduce the friction when the threaded lead screw 34 rotates, making the rotation of the threaded lead screw 34 smoother, thereby reducing energy loss and wear, extending the service life, and ensuring the precise rotation of the threaded lead screw 34 to achieve positioning accuracy.

[0035] Specifically, referring to Figure 3, the adjusting seat 42 is arranged in a U shape, and light bearings 43 are assembled at both ends thereof. Both ends of the small lead screw 44 are rotatably connected to one of the light bearings 43 respectively; two optical axes 46 are also installed on the adjusting seat 42. The two optical axes 46 are respectively arranged on one side of the slider seat 45 and are slidably connected to the slider seat 45; a reciprocating rotary motor 47 is also assembled at one end of the adjusting seat 42, and the output end of the reciprocating rotary motor 47 is connected to one end of the small lead screw 44.

[0036] In this embodiment, during actual use, the user connects a power supply to the reciprocating rotary motor 47, so that the reciprocating rotary motor 47 can drive the small lead screw 44 to rotate. At this time, through the lateral limit of the two optical axes 46 and the rotation between the small lead screw 44 and the light bearing 43, the slider seat 45 engaged outside the small lead screw 44 can drive the high-efficiency cooling fan 48 to move in a reciprocating straight line along the stroke range of the adjusting seat 42, so that the high-efficiency cooling fan 48 can move horizontally above the frame 1 and perform reciprocating and efficient heat dissipation on the metal fittings.

[0037] Furthermore, the light bearings 43 arranged on the adjusting seat 42 can ensure that the rotation of the small lead screw 44 is smoother, thereby reducing energy loss and wear and extending the service life.

[0038] Specifically, referring to Figure 1 , a three-axis laser cutting machine body 2 is assembled and arranged on the frame 1; two groups of linear lead screw modules are assembled horizontally at the bottom of the frame 1, and the three-axis laser cutting machine body 2 is assembled on the two groups of linear lead screw modules and can slide linearly along the horizontal range of the frame 1.

[0039] In this embodiment, the linear lead screw modules arranged on the frame 1 can provide high-precision linear movement for the three-axis laser cutting machine body 2, ensuring that the laser cutting head can be accurately positioned during the processing, so as to achieve precise cutting and processing; at the same time, the linear lead screw modules have high rigidity and stability, can reduce vibration and displacement, and ensure the stability and reliability during the laser cutting process.

[0040] The laser cutting machine for processing metal fittings of the present utility model:

[0041] Step 1: In actual use, when the user needs to perform a cutting operation on a metal fitting, place it on the cutting tabletop of the frame 1, and then adjust the two sets of metal fitting positioning components 3 so that the metal fitting positioning components 3 can limit the metal fitting. During this period, the user connects the power supply to the reciprocating motors 33 in the two sets of metal fitting positioning components 3, so that the reciprocating motors 33 can drive their output ends, thereby rotating the threaded lead screws 34. When the threaded lead screws 34 are rotating, limited by the connection of the two mounting cross beams 37, the nut sleeves 35 outside the threaded lead screws 34 can drive the mounting seats 36 to move linearly along the pitch range of the threads of the threaded lead screws 34. Through the left-handed and right-handed thread settings of the threaded lead screws 34, the four mounting seats 36 can drive the two mounting cross beams 37 to perform an opposing clamping movement or a reverse separating movement.

[0042] Step 2: The user places the metal fitting between the two mounting cross beams 37 and simultaneously adjusts the distance between the two mounting cross beams 37 according to the size of the metal fitting. When the appropriate downward pressure range is adjusted, the user can then rotate several positioning bolts 38, so that the positioning bolts 38 can drive 39 downward until 39 contacts the surface of the metal fitting. At this time, 39 can be used in cooperation with the cutting tabletop of the frame 1 to achieve stable downward pressure positioning of the metal fitting.

[0043] Step 3: After the metal fitting is fixed on the frame 1, the user can then control and drive the linear lead screw module on the frame 1, so that the three-axis laser cutting machine body 2 can move linearly on the frame 1. At the same time, in cooperation with the three-axis control in the three-axis laser cutting machine body 2, finally, the three-axis laser cutting machine body 2 can complete the cutting operation on the metal fitting on the frame 1. The provided metal fitting positioning components 3 can be adjusted in a timely manner for metal fittings of different sizes, thereby achieving stable positioning of the metal fittings.

[0044] Step 4: After the operation of the three-axis laser cutting machine body 2 is completed, the user can drive the high-efficiency heat dissipation component 4 to complete the high-efficiency heat dissipation of the metal fitting. During this period, the user connects the power supply to the reciprocating rotary motor 47, so that the reciprocating rotary motor 47 can drive the small lead screw 44 to rotate. At this time, limited laterally by the two optical axes 46 and in cooperation with the rotation between the small lead screw 44 and the light-duty bearing 43, the slider seat 45 meshing outside the small lead screw 44 can drive the high-efficiency heat dissipation fan 48 to move linearly in a reciprocating manner along the stroke range of the adjustment seat 42. At this time, the user connects the power supply to the high-efficiency heat dissipation fan 48, and the high-efficiency heat dissipation fan 48 can blow the metal fitting in a reciprocating manner, thereby achieving high-efficiency heat dissipation treatment of the metal fitting and the frame 1.

[0045] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
