Description

Technical Field

[0001] This invention relates to the field of aluminum profile machining center technology, and in particular to an aluminum profile machining center and machining method. Background Technology

[0002] In existing aluminum profile processing centers, the aluminum profiles need to be clamped in place before and after cutting. However, the entire process of drilling, milling, cutting, and slitting of the aluminum profile requires a large number of clamps. On the one hand, this can cause unnecessary tolerances during clamping, especially during the cutting process, which requires multiple clamping and loosening operations. On the other hand, it complicates the processing of aluminum profiles, as each processing step requires clamping, which is detrimental to processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an aluminum profile machining center, which uses a rotary milling transfer assembly to drive a rotary milling processing device to move to multiple positions on the profile for milling, and then transfers the profile held by the profile fixture to a cutting device, where the profile is cut into several segments. This aluminum profile machining center can effectively avoid the problem of large processing errors caused by multiple clamping, and also reduce the problem of low processing efficiency caused by clamping.

[0004] The present invention also proposes an aluminum profile processing method, which first drives a rotary milling processing device to move to multiple positions of the profile for milling processing, and then the profile held by the profile fixture is conveyed to the cutting device, and the profile is cut into several segments by the cutting device.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A method for processing aluminum profiles includes the following steps:

[0007] (1) The profile fixture holds the profile; the profile drilling and milling device moves along the length of the profile and performs drilling and milling on multiple positions of the profile;

[0008] (2) The profile clamp releases the profile; the pushing device pushes the profile toward the cutting device, causing the profile to move a specific length unit;

[0009] (3) The profile clamp holds the profile; the cutting device cuts the profile;

[0012] More preferably, in step (1), after the first processing section completes the drilling and milling process, some of the profile fixtures loosen their clamps and move to the first processing section, exposing the second processing section to be drilled and milled; the profile drilling and milling device moves to the second processing section and performs drilling and milling on the exposed second processing section.

[0013] In a further optimized manner, in step (1), before drilling and milling, the clamping end of the pusher device clamps the profile, the first end locator of the pusher device identifies the first end of the profile in place, the pusher device pushes the profile toward the cutting device until the end of the profile is identified by the end locator of the cutting device, and then stops moving. The total length of the profile is calculated by the moving distance of the pusher device.

[0014] In step (1), before drilling and milling, the pusher gradually moves toward the first end of the profile until the first end of the profile contacts the first end locator. Then, the clamping end of the pusher clamps the first end of the profile and pushes the end of the profile toward the end locator.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] The technical solution of this invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0055] An aluminum profile machining center includes: a machining base 2, a feeding device 7, a profile drilling and milling device 1, a cutting device 6, and a profile fixture 5;

[0056] Profile clamp 5 is installed on the processing base 2;

[0057] The pusher 7 is installed on the processing base 2, and clamps and drives the profile from the position of the profile drilling and milling processing device 1 to the position of the cutting device 6;

[0058] The profile drilling and milling processing device 1 is installed on the processing base 2 and can be driven to move to any position on the profile;

[0059] The cutting device 6 is installed on the processing base 2, and the pushing device 7 pushes the profile after drilling and milling from the position of the profile drilling and milling processing device 1 to the position of the cutting device 6 in a straight line.

[0060] This solution provides an aluminum profile processing center. A profile drilling and milling device 1 moves to multiple positions on the profile for drilling and milling (this can be a separate drill and a separate milling cutter; or it can be the same head, replaceable with a drill or a milling cutter). The processed profile is then conveyed to a cutting device 6, where it is cut into several segments. The moving distance of the pusher 7 determines the moving distance of the profile, thus limiting the length that can be cut after the profile enters the cutting device 6. Therefore, multiple clamping of the profile at the cutting device 6 is unnecessary, avoiding the problem of large processing errors caused by multiple clamping. This eliminates the need for clamping steps during profile processing, improving processing efficiency.

[0061] Preferably, it further includes: a first drive system 3;

[0062] The pushing device 7 includes: a pushing base 71 and a pushing robot 72;

[0063] The pusher base 71 is mounted on the first drive system 3 and is driven to move by the first drive system 3; the pusher robot 72 is mounted on the pusher base 71; the pusher robot 72 is used to clamp and move the profile.

[0064] The pusher robot 72 grips the profile and, driven by the first drive system 3, moves the profile from the profile clamp 5 to the cutting device 6. The moving distance of the first drive system 3 is the distance the profile extends into the cutting device 6. Only after the first cut is performed by the cutting device 6 does the first drive system 3 drive the pusher robot 72 to move the profile in the conveying direction of the cutting device 6 (e.g., ...). Figure 1(In the direction of the arrow) the profile is moved, and the cut end continues to be conveyed to the cutting device 6 until the pushing robot 72 stops moving. The distance between the cut end of the profile and the saw blade of the cutting device 6 is the moving distance of the pushing robot 72.

[0065] More preferably, the pushing robot 72 includes: a pushing rod 721, a pushing telescopic driver 722, a fixed clamping plate 723, a movable clamping plate 724, and a pushing connecting arm 725;

[0066] One end of the push rod 721 is connected to the push base 71, and the other end is connected to the fixed end of the push telescopic actuator 722; the fixed clamping plate 723 is installed on the push telescopic actuator 722, and the movable clamping plate 724 is rotatably installed on the fixed clamping plate 723; the output end of the push telescopic actuator 722 is rotatably connected to the movable clamping plate 724 through the push connecting arm 725, which is used to drive one end of the push connecting arm 725 to move linearly, thereby causing the movable clamping plate 724 at the other end to rotate relative to the fixed clamping plate 723, so as to adjust the size of the clamping opening 726 formed between the movable clamping plate 724 and the fixed clamping plate 723.

[0067] The push rod 721 is arranged horizontally, with a push telescopic actuator 722 at one end. A fixed clamping plate 723 is fixed to the fixed end of the push telescopic actuator 722. The two ends of the push arm 725 are rotatably connected to the fixed clamping plate 723 and the movable clamping plate 724, respectively. As shown in the figure, one end of the movable clamping plate 724 is also rotatably connected to the fixed clamping plate 723. When the output end of the push telescopic actuator 722 outputs and drives one end of the push arm 725 to move linearly, the push arm 725 drives the movable clamping plate 724 to rotate relative to the fixed clamping plate 723, causing the clamping jaws formed between the fixed clamping plate 723 and the movable clamping plate 724 to open. The clamping jaws are used to clamp the profile. In this design, the push robot 72 moves under the transmission action of the first drive system 3, driving the profile to move, thereby allowing the profile to extend into the cutting device 6 when the profile clamp 5 is released. The moving distance of the first drive system 3 determines the length of each profile segment cut. The pusher telescopic actuator 722 is a known mechanism with linear drive movement, such as a cylinder.

[0068] In a further optimized manner, the pushing device 7 includes: a pushing gripper assembly 73;

[0069] The pusher gripper assembly 73 includes: a first auxiliary arm 731, a second auxiliary arm 732, a pusher turntable 733, and a pusher gripper driver 734;

[0070] The first end of the first auxiliary arm 731 is rotatably connected to the pusher base 71, the second end of the first auxiliary arm 731 is rotatably connected to the first end of the second auxiliary arm 732, and the second end of the second auxiliary arm 732 is rotatably connected to the pusher turntable 733; the output end of the pusher gripper driver 734 is connected to the first auxiliary arm 731 and is used to drive the first auxiliary arm 731 to extend and retract, thereby driving the pusher turntable 733 to rotate through the second auxiliary arm 732; the pusher turntable 733 is synchronously connected to the pusher robot 72.

[0071] The pusher gripper assembly 73 can adjust the clamping angle of the pusher robot 72 on the profile. For example, in some embodiments, one section of the profile is difficult to clamp. In this case, the rotation of the pusher gripper assembly 73 can drive the pusher robot 72 to rotate, making it easier for the pusher robot 72 to clamp the section. In addition, preferably, the profile drilling and milling processing device 1 will mill various positions of the profile, such as the upper surface, lower surface, and both sides in the direction of movement. For this purpose, this solution preferably adds a pusher gripper assembly 73, which flips the profile and switches the processing surface of the profile to be aligned with the profile drilling and milling processing device 1, so that the profile drilling and milling processing device 1 can quickly process each surface. Specifically, the pusher clamp driver 734 has a telescopic end, such as a cylinder, which can drive a part of the first auxiliary arm 731 to move; the output end of the pusher clamp driver 734 drives a part of the first auxiliary arm 731 to move, causing the first auxiliary arm 731 to rotate around the pusher base 71, and causing the second auxiliary arm 732 to swing; since the output end of the pusher clamp driver 734 is telescopic, its telescopic process can be regarded as a cyclic process, through the first auxiliary arm 731 driving the second auxiliary arm 732 to swing back, driving the pusher turntable 733 to rotate; the pusher turntable 733 rotates synchronously with the pusher rod 721, driving the pusher rod 721 to rotate, and then driving the fixed clamping plate 723 and the movable clamping plate 724 to rotate, so that the profile held by the clamping jaws rotates.

[0072] Further optimization also includes: a fixed-length component;

[0073] The length-fixing component includes: a head positioner 81 and an end positioner 82;

[0074] The first end positioner 81 is installed in the clamp; the last end positioner 82 is disposed close to the cutting device 6; the first end positioner 81 and the last end positioner 82 are respectively located at both ends of the profile, and are used to calculate the positions of the two ends of the profile in order to calculate the length of the profile.

[0075] The length-fixing component can calculate the length of the profile, and the first-end locator 81 located in the clamp can identify the first end of the profile. The pushing device 7 pushes the profile to move, and the clamp drives the first end to move, so that the end of the profile passes through the end locator 82. After the end locator 82 identifies the end, the length of the profile can be determined by calculating the moving distance of the pushing device 7, which has an automatic length-fixing function. The first-end locator 81 is located at the clamp position, which is generally located at the first end of the profile; the end locator 82 is located at the cutting device 6, preferably at the position aligned with the cutting blade, or the end locator 82 can be set at any position of the cutting device 6, and the distance between the end locator 82 and the cutting blade will be taken into account and corrected when calculating the length of the profile.

[0076] Among them, the first-end locator 81 and the last-end locator 82 are known mechanisms with positioning and identification functions, such as infrared identification devices, contact positioning devices, laser identification devices, etc.

[0077] Further optimization also includes: a first drive system 3;

[0078] The first drive system 3 includes: a material pusher drive component 30;

[0079] The feeding drive assembly 30 includes: a first conveying rack 31, a first conveying driver 32, a first gear 33, a first conveying track 34, and a first conveying slider 35;

[0080] The first conveying rack 31 and the first conveying track 34 are respectively installed on the processing base 2; the first conveying driver 32 and the first conveying slider 35 are respectively installed on the pushing device 7; the output end of the first conveying driver 32 is connected to the first gear 33 for driving the first gear 33 to rotate; the first gear 33 meshes with the first conveying rack 31; the first conveying slider 35 is movably engaged with the first conveying track 34.

[0081] The first conveying rack 31 and the first conveying track 34 are respectively installed on the processing base 2; the first conveying driver 32 is respectively installed on the pushing device 7 and the profile drilling and milling processing device 1. The output end of the first conveying driver 32 rotates, driving the first gear 33 to rotate; since the rotation of the first gear 33 is meshed with the first conveying rack 31, the first gear 33 rotates and moves relative to the first conveying rack 31, driving the first conveying driver 32 to move along the first conveying rack 31. Based on the first conveying slider 35 being movably engaged with the first conveying track 34, the pushing device 7 and the profile drilling and milling processing device 1 can move the first conveying track 34, realizing the position adjustment of the pushing device 7 and the profile drilling and milling processing device 1.

[0082] More preferably, it also includes: a second drive system 4;

[0083] Multiple profile clamps 5 are respectively mounted on the second drive system 4 and are driven by the second drive system 4 to move on the processing base 2;

[0084] The second drive system 4 includes: a second transmission rack 41, a second transmission driver 42, a second gear 43, a second transmission track 44, and a second transmission slider 45;

[0085] The second conveying rack 41 and the second conveying track 44 are respectively mounted on the processing base 2; the second conveying driver 42 and the second conveying slider 45 are respectively mounted on the profile fixture 5; the output end of the second conveying driver 42 is connected to the second gear 43 for driving the second gear 43 to rotate; the second gear 43 meshes with the second conveying rack 41; the second conveying slider 45 is movably engaged with the second conveying track 44.

[0086] Specifically, the first drive system 3 and the second drive system 4 can be replaced by known mechanisms with drive functions to drive the profile drilling and milling device 1 and the profile fixture 5 to move linearly or curvilinearly, such as cylinder drive or a combination of motor and lead screw. In one embodiment, the fixed end of the cylinder is mounted on the processing base 2, and the output end is connected to the profile drilling and milling device 1 or the profile fixture 5, driving the profile drilling and milling device 1 or the profile fixture 5 to move; in another embodiment, the output end of the motor is connected to the lead screw, the motor drives the lead screw to rotate, and the nut seat mounted on the lead screw is movable; simply connecting the nut seat to the profile drilling and milling device 1 or the second drive system 4 can drive the profile drilling and milling device 1 or the second drive system 4 to move linearly. In the initial state, the profile fixture 5 clamps the profile at multiple positions; the profile drilling and milling device 1 of this solution can move to any position of the profile, ensuring that the processing tool 146 can move to any position of the profile. Furthermore, the machining tool 146 of the profile drilling and milling processing device 1 first performs drilling and milling processing on multiple positions of the profile, then the profile clamp 5 loosens its clamping jaws, the pusher device 7 pushes the profile to move, causing the profile to move a specific unit distance in the direction of the cutting device 6, and then the profile clamp 5 clamps the profile again.

[0087] The second transmission rack and the second transmission track are respectively installed on the processing base; the second transmission driver is installed on the profile fixture 5. The output end of the second transmission driver rotates, driving the second gear to rotate; since the rotation of the second gear is meshed with the second transmission rack, the second gear rotates and moves relative to the second transmission rack, driving the second transmission driver to move along the second transmission rack. Based on the second transmission slider being movably engaged with the second transmission track, the profile fixture 5 can move the second transmission track, realizing the position adjustment of the profile fixture 5.

[0088] Further optimization also includes: a first drive system 3;

[0089] The first drive system 3 includes: a drilling and milling drive mechanism 12;

[0090] The profile drilling and milling processing device 1 includes: a drilling and milling base frame 11, a movable base plate 13, and a drilling and milling processing section 14;

[0091] The output end of the drilling and milling drive mechanism 12 is connected to the movable base plate 13, and is used to drive the movable base plate 13 to move laterally along the X-axis, move laterally along the Y-axis, and / or move vertically along the Z-axis; the drilling and milling processing part 14 is mounted on the movable base plate 13.

[0092] The drilling and milling processing unit 14 includes: a first angle driver 141, a first angle adjustment plate 142, a second angle driver 143, a second angle adjustment plate 144, a drilling and milling driver 145, and a processing tool 146;

[0093] The first angle driver 141 is mounted on the movable base plate 13, and its output end is connected to the first angle adjustment plate 142 for driving the first angle adjustment plate 142 to rotate about the parallel axis of the X-axis. The second angle driver 143 is mounted on the first angle adjustment plate 142, and its output end is connected to the second angle adjustment plate 144 for driving the second angle adjustment plate 144 to rotate. The rotation axis of the second angle driver 143 is perpendicular to the rotation axis of the first angle driver 141. The drilling and milling driver 145 is mounted on the second angle adjustment plate 144, and its output end is connected to the machining tool 146 for driving the machining tool 146 to rotate.

[0094] This solution provides a profile drilling and milling processing device 1, which drives the processing tool 146 to move along the X, Y and Z axes through the drilling and milling drive mechanism 12. Combined with the first angle driver 141 and the second angle driver 143 to adjust the angle of the processing tool 146, the processing tool 146 can perform milling on multiple surfaces of the profile, improve the milling capability, and solve the problem of limited milling angle in the prior art.

[0095] Specifically, the drilling and milling drive mechanism 12 is a known mechanism with a driving and moving function. It can drive the drilling and milling processing unit 14 to move along the X-axis, Y-axis, and Z-axis, so that after the drilling and milling processing unit 14 is positioned, the processing tool 146 is brought closer to the processing surface of the profile. For the processing of the processing tool 146, it is only necessary to start the drilling and milling driver 145, which drives the processing tool 146 to rotate, so that the required shape can be processed on the surface of the profile. For the adjustment of the processing angle of the processing tool 146, the first angle driver 141 is mounted on the movable base plate 13. The output end of the first angle driver 141 drives the first angle adjustment plate 142 to rotate, which in turn drives the second angle driver 143 to rotate. The second angle driver 143 then drives the second angle adjustment plate 144 to rotate, which in turn drives the drilling and milling driver 145 on the second angle adjustment plate 144 to rotate, thereby adjusting the angle of the processing tool 146. After the adjustment of the two angle drivers, the position of the processing tool 146 can be adjusted to multiple sides of the profile, thereby improving the processing capability of the processing tool 146 on the profile.

[0096] The drilling and milling drive mechanism 12 is a known mechanism that drives linear or curved movement. In one embodiment, the drilling and milling drive mechanism 12 includes a cylinder. The output end of the cylinder is connected to the drilling and milling machining part 14, driving the drilling and milling machining part 14 to move laterally along the X-axis, laterally along the Y-axis, and / or move vertically along the Z-axis. In another embodiment, the drilling and milling drive mechanism 12 includes a motor and a lead screw. The output end of the motor is connected to the lead screw, and the motor drives the lead screw to rotate. A nut seat mounted on the lead screw is movable. By simply connecting the nut seat to the drilling and milling machining part 14, the drilling and milling machining part 14 can be driven to move laterally along the X-axis, laterally along the Y-axis, and / or move vertically along the Z-axis. The first angle actuator 141, the second angle actuator 143, and the milling / drilling actuator 145 are known mechanisms with drive rotation, such as a motor or a combination of a motor and a reducer. The rotation axes of the first angle actuator 141 and the second angle actuator 143 are perpendicular. The first angle actuator 141 drives the first angle adjusting plate 142 to rotate, and the second angle actuator 143 on the first angle adjusting plate 142 drives the second angle adjusting plate 144 to rotate around an axis perpendicular to the first angle actuator 141, thereby improving the flexibility of machining tool angle adjustment. The machining tool 146 includes a milling cutter and a drill cutter.

[0097] Preferably, it further includes: a tool changing assembly 15;

[0098] The tool changing assembly 15 includes: a tool holder 151;

[0099] A plurality of the machining tools 146 are detachably mounted on the tool holder 151; the drilling and milling driver 145 is driven close to the tool holder 151, and the output end of the drilling and milling driver 145 is used to mount and remove the machining tools 146 from the tool holder 151.

[0100] The tool holder 151 is equipped with multiple machining tools 146 of different sizes and types, which can be replaced by the drilling and milling driver 145 to adapt to different machining applications. The drilling and milling driver 145 moves towards the tool holder 151, driven by the drilling and milling drive mechanism 12, the first angle driver 141, and / or the second angle driver 143, so that the output end of the drilling and milling driver 145 is close to and connected to the machining tool 146, or the output end of the drilling and milling driver 145 places the original machining tool 146 on the tool holder 151 and replaces it with a new machining tool 146. The tool holder 151 can be equipped with a known fixture to fix the machining tool 146.

[0101] More preferably, the tool holder 151 is connected to the top of the drilling and milling base 11, and the tool holder 151 is suspended in the air; the drilling and milling driver 145 rotates the output end from bottom to top to the bottom of the tool holder 151.

[0102] As shown in the figure, the tool holder 151 is located on top of the drilling and milling base 11. When the first angle adjustment plate 142 rotates around the parallel axis of the X-axis, the drilling and milling driver 145 abuts against the tool holder 151 from bottom to top around the parallel axis of the X-axis. Since the drilling and milling driver 145 rotates from bottom to top, the machining tool 146 is more easily placed at the output end of the drilling and milling driver 145 under the action of gravity, and the machining tool 146 can be changed faster, effectively shortening the tool change time and improving the machining efficiency of the profile. In addition, the tool holder 151 is suspended, and the distribution of the tool holder 151 reduces the lateral space occupied by the overall structure, making the overall structure more compact.

[0103] In a further optimized manner, the tool changing assembly 15 includes: a frame movement driver 152 and a frame connecting plate 153;

[0104] The frame movement driver 152 is mounted on the drilling and milling base frame 11, and the output end of the frame movement driver 152 is connected to the frame connecting plate 153 for driving the frame connecting plate 153 to move along the X-axis; the frame connecting plate 153 is connected to the tool holder 151.

[0105] The frame movement driver 152 drives the frame connecting plate 153 to move along the X-axis, thereby driving the tool holder 151 to move along the X-axis and moving multiple machining tools 146 of the tool holder 151. This synchronizes the position of the tool holder 151 with the position of the drilling and milling driver 145, so that when changing tools, the drilling and milling driver 145 only needs to rotate around the parallel axis of the X-axis to reach the position of the machining tool 146, thus improving tool changing efficiency. The frame movement driver 152 is a known mechanism with a driving movement function, such as a cylinder. The output end of the cylinder is connected to the frame connecting plate 153, driving the frame connecting plate 153 to move along the X-axis.

[0106] Alternatively, the tool changing assembly 15 may include: a carriage rotation driver 154;

[0107] The frame rotation driver 154 is connected to the frame connecting plate 153; the output end of the frame rotation driver 154 is connected to the tool holder 151 and is used to drive the tool holder 151 to rotate.

[0108] The turret rotation driver 154 drives the tool holder 151 to rotate, so that the machining tools 146 on the tool holder 151 rotate, and different machining tools 146 pass through the output end of the drilling and milling driver 145. In order to provide the drilling and milling driver 145 with the required machining tools 146 through rotation, the drilling and milling driver 145 avoids the situation where the drilling and milling driver 145 needs to perform multiple X, Y, and Z axis position adjustments to reach the machining tools 146, thereby improving the tool changing efficiency of the drilling and milling driver 145.

[0109] Preferably, the drilling and milling drive mechanism 12 includes: an X-axis drive assembly 121;

[0110] The X-axis drive assembly 121 includes: an X-axis transmission rack 1211, an X-axis transmission driver 1212, an X-axis gear 1213, an X-axis transmission track 1214, and an X-axis transmission slider 1215;

[0111] The X-axis transmission rack 1211 and the X-axis transmission track 1214 are respectively mounted on the machining base 2; the X-axis transmission driver 1212 and the X-axis transmission slider 1215 are respectively mounted on the drilling and milling base 11; the output end of the X-axis transmission driver 1212 is connected to the X-axis gear 1213 for driving the X-axis gear 1213 to rotate; the X-axis gear 1213 meshes with the X-axis transmission rack 1211; the X-axis transmission slider 1215 is movably engaged with the X-axis transmission track 1214.

[0112] X-axis transmission rack 1211 and X-axis transmission track 1214 are respectively mounted on machining base 2; X-axis transmission driver 1212 is respectively mounted on drilling and milling base 11. The output end of X-axis transmission driver 1212 rotates, driving X-axis gear 1213 to rotate; since X-axis gear 1213 and X-axis transmission rack 1211 are meshed, X-axis gear 1213 rotates and moves relative to X-axis transmission rack 1211, driving X-axis transmission driver 1212 to move along X-axis transmission rack 1211. Based on the X-axis transmission slider 1215 being movably engaged with X-axis transmission track 1214, drilling and milling base 11 can move X-axis transmission track 1214, and drilling and milling base 11 then drives machining tool to move along X-axis, realizing the position adjustment of machining tool on X-axis.

[0113] More preferably, the drilling and milling drive mechanism 12 includes: a Z-axis drive assembly 123 and a Y-axis drive assembly 122;

[0114] The Z-axis drive assembly 123 includes: a Z-axis driver 1230 and a Z-axis lifting plate 1231;

[0115] The Z-axis driver 1230 is mounted on the drilling and milling base 11; the output end of the Z-axis driver 1230 is connected to the Z-axis lifting plate 1231 and is used to drive the Z-axis lifting plate 1231 to move up and down along the Z-axis.

[0116] The Y-axis drive assembly 122 includes: a Y-axis mounting base 1221 and a Y-axis driver 1220;

[0117] The Y-axis fixed base 1221 is mounted on the Z-axis lifting plate 1231; the Y-axis driver 1220 is mounted on the Y-axis fixed base 1221, and the output end of the Y-axis driver 1220 is connected to the movable base plate 13 for driving the movable base plate 13 to move along the Y-axis.

[0118] The output of the Z-axis driver 1230 drives the Z-axis lifting plate 1231 to move along the Z-axis, which in turn moves the Y-axis fixed seat 1221 on the Z-axis lifting plate 1231 along the Z-axis. This, in turn, moves the movable base plate 13 connected to the Y-axis driver 1220 along the Z-axis, thus moving the drilling and milling driver 145 along the Z-axis. The output of the Y-axis driver 1220 is connected to the movable base plate 13, driving the movable base plate 13 to move along the Y-axis, which in turn moves the drilling and milling driver 145 on the movable base plate 13 along the Y-axis. Therefore, the drilling and milling driver 145 can be adjusted via the X-axis drive assembly 121, the Y-axis drive assembly 122, and the Z-axis drive assembly 123, enabling movement along the X, Y, and Z axes, thus improving the flexibility of the drilling and milling driver 145.

[0119] In a further optimized manner, the Z-axis drive assembly 123 includes: a Z-axis slider 1235 and a Z-axis track 1236;

[0120] One of the Z-axis slider 1235 and the Z-axis track 1236 is installed on the Z-axis lifting plate 1231, and the other is installed on the drilling and milling base frame 11; the Z-axis slider 1235 is movably engaged with the Z-axis track 1236;

[0121] The Y-axis drive assembly 122 includes: a Y-axis conveying slider 1225 and a Y-axis conveying track 1226;

[0122] One of the Y-axis conveying slider 1225 and the Y-axis conveying track 1226 is installed on the Z-axis lifting plate 1231, and the other is installed on the movable base plate 13; the Y-axis conveying slider 1225 is movably engaged with the Y-axis conveying track 1226.

[0123] As shown in the figure, the Y-axis conveyor slider 1225 is mounted on the Z-axis lifting plate 1231, the Y-axis conveyor track 1226 is mounted on the movable base plate 13, the Y-axis conveyor slider 1225 is engaged with the Y-axis conveyor track 1226, and the movable base plate 13 moves relative to the Z-axis lifting plate 1231 along the Y-axis. As shown in the figure, the Z-axis slider 1235 is mounted on the Z-axis lifting plate 1231, the Z-axis track 1236 is mounted on the drilling and milling base frame 11, the Z-axis slider 1235 is engaged with the Z-axis track 1236, and the Z-axis lifting plate 1231 moves relative to the drilling and milling base frame 11 along the Z-axis.

[0124] Optimally, the Z-axis driver 1230 includes: a Z-axis motor 1232, a Z-axis screw 1233, and a Z-axis nut seat 1234;

[0125] The Z-axis motor 1232 is mounted on the drilling and milling base 11, and the output end of the Z-axis motor 1232 is connected to the Z-axis screw 1233 for driving the Z-axis screw 1233 to rotate; the Z-axis nut seat 1234 is movably fitted to the Z-axis screw 1233 along the Z-axis through a threaded structure; the Z-axis nut seat 1234 is connected to the Z-axis lifting plate 1231;

[0126] The Y-axis driver 1220 includes: a Y-axis transmission rack 1222, a Y-axis transmission motor 1223, and a Y-axis gear 1224;

[0127] The Y-axis transmission rack 1222 is mounted on the movable base plate 13; the Y-axis transmission motor 1223 is mounted on the Y-axis fixed base 1221; the output end of the Y-axis transmission motor 1223 is connected to the Y-axis gear 1224 for driving the Y-axis gear 1224 to rotate; the Y-axis gear 1224 meshes with the Y-axis transmission rack 1222.

[0128] Z-axis motor 1232 drives Z-axis screw 1233 to rotate. Z-axis nut seat 1234 mounted on Z-axis screw 1233 is movable on Z-axis screw 1233. Simply connect Z-axis nut seat 1234 to Z-axis lifting plate 1231 to drive Z-axis lifting plate 1231 to move up and down along Z-axis.

[0129] The output end of the Y-axis transmission motor 1223 rotates, driving the Y-axis gear 1224 to rotate. Since the rotation of the Y-axis gear 1224 is meshed with the Y-axis transmission rack 1222, the rotation of the Y-axis gear 1224 and its relative movement relative to the Y-axis transmission rack 1222 causes the Y-axis transmission motor 1223 to move along the length direction of the Y-axis transmission rack 1222. Based on the fact that the Y-axis transmission slider 1225 is movably engaged with the Y-axis transmission track 1226, the movable base plate 13 can move on the Y-axis transmission track 1226 and move along the Y-axis, thus realizing the position adjustment of the machining tool 146 on the Y-axis.

[0130] The drilling and milling driver 145 has two output terminals, which are arranged in opposite directions.

[0131] The drilling and milling driver 145 preferably has two output ends, which are used to install machining tools 146 respectively, so that the drilling and milling driver 145 can simultaneously install two machining tools 146. During the drilling and milling process, the drilling and milling driver 145 can directly switch to use machining tools 146 of different specifications as needed, which can avoid the problem of changing tools again.

[0132] A method for processing aluminum profiles includes the following steps:

[0133] (1) The profile clamp 5 holds the profile; the profile drilling and milling device 1 moves along the length of the profile and performs drilling and milling on multiple positions of the profile;

[0134] The profile has a certain length, and this solution only requires the profile drilling and milling processing device 1 to first perform drilling and milling processing on the profile. The first drive system 3 drives the movement, and the processing tool 146 first performs milling processing at any position on the profile. Here, the drilling and milling processing does not emphasize that multiple parts of the profile must be drilled and milled. Because only some parts of the profile need drilling and only some parts need milling, the drilling and milling processing here refers to completing drilling and milling processing as a whole.

[0135] (2) The profile clamp 5 releases the profile; the pusher 7 pushes the profile toward the cutting device 6, causing the profile to move a specific length unit;

[0136] (3) Profile clamp 5 holds the profile; cutting device 6 cuts the profile;

[0137] Repeat steps (2) and (3).

[0138] In a further optimized manner, in step (1), before drilling and milling, the profile fixture 5 is automatically assigned to multiple positions of the profile, and the first processing section of the profile is exposed between two adjacent profile fixtures 5; the profile drilling and milling device 1 moves to the first processing section and performs drilling and milling on multiple first processing sections.

[0139] Before drilling and milling, the system allocates profile clamps 5 according to the length of the profile, so that the profile clamps 5 are pressed as tightly as possible against the section of the profile that does not need to be machined, exposing the first machining section. The profile drilling and milling processing device 1 moves to the first machining section and performs drilling and milling processing on the exposed first machining section.

[0140] More preferably, in step (1), after the first processing section completes the drilling and milling process, part of the profile fixture 5 loosens its clamping jaws and moves to the first processing section, exposing the second processing section to be drilled and milled; the profile drilling and milling device 1 moves to the second processing section and performs drilling and milling on the exposed second processing section.

[0141] The system calculates the length of the profile and assigns the position of the profile fixture 5 accordingly. For profiles with fewer processing stations, where there is only a first processing section and no second processing section is needed, the profile drilling and milling device 1 only needs to move to the first processing section for processing before moving to the cutting device 6. However, for profiles with even fewer processing stations, the profile fixture 5 can be initially assigned to the second processing section. The profile drilling and milling device 1 processes the first processing section first, then moves the profile fixture 5 to the first processing section, exposing the second processing section of the profile. The profile drilling and milling device 1 then performs drilling and milling on the second processing section. Thus, this solution allows for one-time drilling and milling on the profile surface. The profile fixture 5 and the other fixture have coordination capabilities, and the position of the profile fixture 5 will not be repeatedly moved.

[0142] In step (1), before drilling and milling, the clamping end of the pusher 7 clamps the profile, the head end locator 81 of the pusher 7 identifies the head end of the profile in place, the pusher 7 pushes the profile toward the cutting device 6 until the end of the profile is identified by the end locator 82 of the cutting device 6, and then stops moving. The total length of the profile is calculated by the moving distance of the pusher 7.

[0143] In addition to its pushing function, the pushing device 7 also performs profile positioning and length determination. The end positioner 81 at the clamping end of the pushing device 7 identifies the profile's first end as it is in position. The pushing device 7 moves the profile while clamping it, driving the profile's end to the end positioner 82. The pushing device 7 then stops moving, aligning the profile's end with the end positioner 82, thus achieving profile positioning. Simultaneously, the moving distance of the pushing device 7 can be calculated. When the end positioner 81 identifies the profile's first end, the pushing device 7 moves, driving the profile's end to the end positioner 82, positioning both ends of the profile. The total length of the profile can then be calculated from the moving distance of the pushing device 7. Once the total length of the profile is calculated, the system can allocate profile fixtures 5 according to the profile's length, improving the profile processing efficiency.

[0144] In step (1), before drilling and milling, the pusher 7 gradually moves toward the first end of the profile until the first end of the profile contacts the first end locator 81. Then, the clamping end of the pusher 7 clamps the first end of the profile and pushes the end of the profile toward the end locator 82.

[0145] The first end positioner 81 and the last end positioner 82 are preferably connected to the pusher device 7 via communication or electrical connection. When the first end positioner 81 contacts the profile, it controls the clamping end of the pusher device 7 to clamp the first end of the profile. Under the driving action of the pusher device 7, the last end of the profile is driven to move to the recognition area of ​​the last end positioner 82. The last end positioner 82 can control the pusher device 7 to stop moving, thereby positioning the first and last ends of the profile and achieving precise length positioning.

[0146] The technical principles of this solution have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this solution and should not be construed as limiting the scope of protection of this solution in any way. Based on this explanation, those skilled in the art can readily conceive of other specific implementations of this solution without inventive effort, and these implementations will all fall within the scope of protection of this solution.
