Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing equipment, and in particular to a CNC drilling and milling machine for aluminum profiles. Background Technology

[0002] With the rapid development of industrial technology and the continuous upgrading of manufacturing, the requirements for the precision and efficiency of aluminum profile processing are becoming increasingly stringent.

[0003] In the prior art, Chinese utility model patent application number CN202021088481.8 discloses a multi-angle CNC drilling and milling machine. This device connects the two ends of a support rod to a rotating shaft via a fixed plate, enabling the support rod and its clamping body to rotate eccentrically along the shaft. A tilting assembly on the machine body allows the support rod to rotate automatically. A swinging structure composed of a tilting cylinder, guide rail, slider, and connecting rod allows the support rod and its clamping body to rotate within a certain angle. At 0°, 90°, and -90° angles, the clamping body can drag three faces of the aluminum profile upwards, and the spindle motor performs drilling and milling on each face sequentially. However, this technology has the following drawbacks: Firstly, during drilling and milling at 90° and -90° angles, the clamping body obstructs part of the aluminum profile, making it impossible to drill and mill the obstructed portion. Secondly, the drilling and milling debris is easily scattered, posing a risk of injury and making cleanup extremely difficult.

[0004] In summary, a key challenge in the drilling and milling process of aluminum profiles is achieving three-sided drilling and milling without obstruction by the clamping body, thus preventing chip splashing. Therefore, we propose a CNC drilling and milling machine for aluminum profiles to address these issues. Utility Model Content

[0008] Preferably, the first clamping mechanism includes two first sliders symmetrically arranged in a slide groove, and the first sliders are slidably connected to the slide groove. A first driving assembly is provided in the worktable. A first support plate is fixedly installed on the top of the first slider. A first mounting plate is fixedly installed on the side of the top of the first support plate near the rotating shaft. A first clamping plate perpendicular to the first mounting plate is provided on one side of the top of the first support plate. A first cylinder is installed on the side of the first mounting plate away from the rotating shaft. A first limiting plate is hinged to the extension end of the first cylinder. The end of the first limiting plate away from the first cylinder is hinged to the first clamping plate.

[0009] Preferably, the first drive assembly includes a first drive motor, which is fixedly mounted on one side of the worktable. The output shaft of the first drive motor passes through the worktable and is connected to a first lead screw with double threads. The two ends of the first lead screw are rotatably connected to the inner wall of the slide groove, and the surface of the first lead screw is threadedly connected to the first slider.

[0010] Preferably, the second clamping mechanism includes two second sliders, which are slidably connected in a groove between the two sliders. The second sliders are slidably connected to the surface of the first lead screw. A second driving assembly is provided in the worktable. A second support plate is fixedly installed on the top of the second slider. A second clamping plate is provided on the top of the second support plate on the same side as the first clamping plate. A second mounting plate is fixedly installed on the top of the second support plate away from the second clamping plate. A second cylinder is installed on the side of the second mounting plate close to the second clamping plate. A second limiting plate is fixedly installed on the extension end of the second cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When drilling and milling the profile body on three sides, it is not affected by the obstruction of the clamping body. Through the movable first clamping mechanism, second clamping mechanism and second drive assembly, the clamping position can be flexibly adjusted according to the processing requirements when drilling and milling the profile body on three sides. When it is necessary to drill and mill the part obstructed by the second clamping mechanism, the second slider is moved by the second drive assembly. Since the profile body and the rotating roller of the second clamping mechanism are slidably connected, the obstructed part can be exposed for processing, thereby effectively avoiding the obstruction of the clamping body on the profile body, ensuring the integrity and accuracy of processing, and improving the processing quality and efficiency of aluminum profiles.

[0015] 2. To prevent chip splashing and facilitate chip cleaning, chip guide rubber is installed around the milling cutter in the three-axis linkage tool set, and a chip collection groove is installed under the worktable. During drilling and milling, the chips are blocked by the chip guide rubber and fall into the chip collection groove along the slide, preventing chip splashing and reducing the risk of injury to operators. At the same time, operators only need to open the door of the chip collection groove periodically to clean the chips, making chip cleaning easier and more convenient, improving the working environment, and enhancing the safety and sustainability of production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1-4 A CNC drilling and milling machine for aluminum profiles includes a bed 1. A control panel 2 is located on one side of the bed 1 for inputting machining parameters, starting or stopping the equipment, and adjusting the machining mode. This control panel is electrically connected to various electrical control components on the drilling and milling machine. Two symmetrical support plates 3 are located on both sides of the top of the bed 1. A rotating shaft 4 is rotatably mounted on one side of each support plate 3. A worktable 5 is fixedly installed between the two rotating shafts 4. The rotating shafts 4 pass through the support plates 3 and are connected to a drive component 11, which provides power for the rotation of the worktable 5. This drive component 11 can be a servo motor, a rotary cylinder, etc. The drive component 11 can precisely control the rotation angle and speed of the worktable 5. A three-axis linkage tool set 6 is located above the worktable 5. The three-axis linkage tool set 6 is slidably connected to the bed 1. Through the movement of three axes, it realizes the precise processing of aluminum profiles. The worktable 5 is provided with a sliding groove 7 that runs through the top and bottom of the worktable 5. A first clamping mechanism for clamping two end faces of the aluminum profile is slidably connected in the sliding groove 7. A second clamping mechanism 9 for clamping three sides of the aluminum profile is provided between the first clamping mechanisms 8. The position of the first clamping mechanism 8 can be adjusted to adapt to the processing requirements of aluminum profiles of different lengths. The position of the second clamping mechanism 9 can be adjusted to adjust the position of the aluminum profile during processing, so that the obscured part is exposed for processing. The chip removal component 10 is provided on the bed 1 to avoid chip splashing and make the chip easy to clean.

[0024] The first clamping mechanism 8 includes two first sliders 81 symmetrically arranged in the slide groove 7, and the first sliders 81 are slidably connected to the slide groove 7. A first drive assembly 87 is provided in the worktable 5. The first drive assembly 87 is used to adjust the position of the first sliders 81. A first support plate 82 is fixedly installed on the top of the first sliders 81. A first mounting plate 84 is fixedly installed on the side of the top of the first support plate 82 near the rotating shaft 4. A first clamping plate 8 is provided on one side of the top of the first support plate 82, perpendicular to the first mounting plate 84. 3. A first cylinder 85 is installed on the side of the first mounting plate 84 away from the rotating shaft 4. A first limiting plate 86 is hinged to the extension end of the first cylinder 85. The end of the first limiting plate 86 away from the first cylinder 85 is hinged to the first clamping plate 83. When the first cylinder 85 is activated to extend, the extension of the first cylinder 85 causes the first limiting plate 86 to be close to both ends of the profile. Since the first limiting plate 86 is hinged to the first cylinder 85 and the first clamping plate 83, the profile can be stably clamped regardless of whether the end face is a right angle or an inclined surface.

[0025] The first drive assembly 87 includes a first drive motor 871, which is fixedly mounted on one side of the worktable 5. The output shaft of the first drive motor 871 passes through the worktable 5 and is connected to a first lead screw 872 with double threads. The two ends of the first lead screw 872 are rotatably connected to the inner wall of the slide groove 7. The surface of the first lead screw 872 is threadedly connected to the first slider 81 and rotates under the drive of the first drive motor 871. The double threads on the surface of the first lead screw 872 are threadedly connected to the two first sliders 81 respectively, so as to realize the synchronous movement or reverse movement of the two first sliders 81.

[0026] The second clamping mechanism 9 includes two second sliders 91, which are slidably connected in a groove 7 between the two first sliders 81. The second sliders 91 are slidably connected to the surface of the first lead screw 872 to ensure that the first clamping mechanism 8 and the second clamping mechanism 9 do not interfere with each other during movement. A second drive assembly 97 is provided in the worktable 5. The second drive assembly 97 is used to adjust the position of the second sliders 91. A second support plate 92 is fixedly installed on the top of the second sliders 91. The top of the second support plate 92 is provided with a part on the same side as the first clamping plate 83. The second clamping plate 93 and the second support plate 92 are fixedly provided with a second mounting plate 94 on the top of the side away from the second clamping plate 93. A second cylinder 95 is installed on the side of the second mounting plate 94 close to the second clamping plate 93. A second limiting plate 96 is fixedly installed on the extended end of the second cylinder 95. Rotary rollers are rotatably installed on the top of the second support plate 92 and the side of the second clamping plate 93 and the second limiting plate 96 that are close to each other. When the second cylinder 95 is activated to extend, the second limiting plate 96 clamps the other side of the profile body, so that the profile body is firmly clamped.

[0027] The second drive assembly 97 includes a second drive motor 971, which is fixedly mounted on one side of the worktable 5. The output shaft of the second drive motor 971 passes through the worktable 5 and is connected to a second lead screw 972. The two ends of the second lead screw 972 are rotatably connected to the inner wall of the slide groove 7. The surface of the second lead screw 972 is threadedly connected to the second slider 91 and slidably connected to the first slider 81. Driven by the second drive motor 971, the second lead screw 972 rotates, and its surface thread is threadedly connected to the second slider 91, realizing the movement of the second slider 91. At the same time, the surface thread of the second lead screw 972 is slidably connected to the first slider 81, ensuring that the first clamping mechanism 8 and the second clamping mechanism 9 do not interfere with each other during movement. Because the three sides of the profile body clamped by the second clamping mechanism 9 are all provided with rotating rollers, when the second slider 91 moves, the profile body and the second clamping mechanism 9 are slidably connected, thereby exposing the covered part for processing.

[0028] The chip removal assembly 10 includes a chip guide rubber sheet disposed around the end mill in the three-axis linkage tool set 6 and a chip collection groove 101 disposed on the bed 1 below the worktable 5. The chip collection groove 101 has a chip removal opening on its side wall away from the three-axis linkage tool set 6, and a door panel 102 is hinged to the opening. During the machining process, the chip guide rubber sheet blocks the waste chips to prevent them from splashing and guides them into the slide 7, so that they fall into the chip collection groove 101 along the slide 7. When it is necessary to clean the waste chips, the operator can open the door panel 102 to clean the waste chips out of the chip collection groove 101. When closed, the sealing of the chip collection groove 101 is ensured to prevent waste chip leakage.

[0029] Working principle:

[0030] First, based on the length of the aluminum profile to be drilled and milled, the first drive motor 871 in the first drive assembly is started. The first drive motor 871 drives the first lead screw 872 with double threads to rotate, thereby moving the two first sliders 81 that slide symmetrically in the slide groove 7 to the appropriate position, placing both ends of the aluminum profile on the first support plate 82. At this time, since the top of the rotating roller at the upper end of the second support plate 92 and the top of the first support plate 82 are on the same plane, the profile body is also placed on the rotating roller at the upper end of the second support plate 92. One side of the profile is tightly attached to the first clamping plate 83, and the second... The top of the rotating roller on the inner side of the clamping plate 93 is on the same plane as the inner side of the first clamping plate 83, and one side of the profile body is also tightly attached to the rotating roller on the inner side of the second clamping plate 93. Then, the first cylinder 85 is activated to extend, and the extension of the first cylinder 85 causes the first limiting plate 86 to be close to both ends of the profile. Since the first limiting plate 86 is hinged to the first cylinder 85 and the first clamping plate 83, the profile can be stably clamped regardless of whether the end face of the profile is a right angle or an inclined plane. At the same time, the second cylinder 95 is activated to extend, so that the second limiting plate 96 clamps the other side of the profile body. Thus, the profile is firmly clamped.

[0031] Then, the three-axis linkage tool set 6 and the rotary drive 11 are started. The rotary drive 11 drives the worktable 5 to rotate, so that the aluminum profile can be processed at different angles such as 0°, 90° and -90°. When it is necessary to drill and mill the part that is covered by the second clamping mechanism 9, the second drive motor 971 in the second drive assembly is started. The second drive motor 971 drives the second lead screw 972 to rotate, so that the second slider 91 moves in the slide groove 7. Since the three sides of the profile body that are clamped by the second clamping mechanism 9 are rotating rollers, when the second slider 91 moves, the profile body and the second clamping mechanism 9 are slidably connected, so that the covered part is exposed for processing.

[0032] During the drilling and milling process, since the slide 7 runs through the top and bottom of the worktable 5, and the milling cutter in the three-axis linkage tool group 6 is equipped with a chip guide rubber, the chips will be blocked by the chip guide rubber and fall into the chip collection groove 101 set on the bed 1 below the worktable 5 along the slide 7. Then, the door panel 102 of the chip collection groove 101 can be opened periodically to clean the waste chips.
