Description

Technical Field

[0001] This utility model belongs to the field of aluminum door and window processing technology, specifically relating to a five-axis machining center for aluminum materials. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Currently, in the aluminum door and window processing industry, milling of aluminum profiles primarily involves single-pass, single-profile processing. For complex profiles requiring the machining of multiple end faces, the main processing concept is stationary equipment with moving profiles. Each time an end face in a spatial position is machined, the profile needs to be removed from the processing equipment, resulting in high manual labor intensity and long processing time. Furthermore, the positioning device often shifts during repeated positioning, causing the finished workpiece to deviate from its original position, especially when machining workpieces with complex curved surfaces or numerous holes, making operation even more difficult. Existing five-axis machining centers cannot complete multi-face machining of arc-shaped or irregularly shaped materials in one operation. Moreover, after completing auxiliary machining of multiple faces, the material needs to be manually transferred to a saw for sawing, requiring repeated positioning, which further reduces processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a five-axis machining center for aluminum materials, which can at least solve one of the above-mentioned technical problems.

[0005] To achieve the above objectives, one or more embodiments of this utility model provide a five-axis machining center for aluminum materials, including a frame, a limiting device, and a gantry device. The limiting device is disposed on both sides of the frame, and multiple sets of clamps are evenly distributed on the upper side of the frame. The clamps slide along the X-axis direction of the frame. The gantry device includes two columns connected to the side of the frame, and the columns are provided with an X-axis mechanism that slides along the frame. A Y-axis mechanism is provided at the top of the gantry device.

[0006] Furthermore, two first linear guide slider pairs are distributed in parallel on the upper part of the frame, and a second linear guide slider pair and a third linear guide slider pair are distributed on both sides of the frame in the width direction, with a first rack and a second rack distributed in the middle of the second linear guide slider pair and the third linear guide slider pair, respectively.

[0007] Furthermore, the first rack is located in the middle of the second linear guide slider pair, the second rack is located in the middle of the third linear guide slider pair, and baffles are provided on both sides of the first rack and the second rack in the length direction.

[0008] Furthermore, the limiting device includes a push plate, which is pushed by a first cylinder and moves up and down along the fourth linear guide slider pair.

[0009] Furthermore, the upper part of the clamp is provided with a fifth linear guide slider pair, the lower part of the clamp is provided with a clamping block, and the two ends of the fifth linear guide slider pair are provided with sliding blocks; the clamping block moves linearly on the fifth linear guide slider pair by being pushed by the second cylinder.

[0010] Furthermore, a sixth linear guide slider pair is provided on the outer side of the column of the gantry device. The sixth linear guide slider pair is provided with a tool magazine installed close to the frame. The tool magazine includes multiple milling cutters and a saw blade installed in an umbrella shape.

[0011] Furthermore, the bottom of the column is connected to the second linear guide slider pair and the third linear guide slider pair on both sides of the frame.

[0012] Furthermore, a servo motor is also provided on the column, and the motor shaft of the servo motor is provided with transmission gears that mesh with the first rack and the second rack respectively.

[0013] Furthermore, the gantry device is also equipped with a lifting device connected to the Y-axis mechanism, and the lifting device is connected to the Y-axis mechanism through a Y-axis sliding plate.

[0014] Furthermore, the lifting device is equipped with a seventh linear guide slider pair and a Z-axis slide plate, and a dual-axis swing head is provided at the lower end of the lifting device. The dual-axis swing head is connected to the Z-axis slide plate, and the dual-axis swing head includes a first swing head that rotates vertically around the lifting device and a second swing head that rotates horizontally.

[0015] The beneficial effects of one or more of the above technical solutions are as follows:

[0016] This invention utilizes a clamping device with evenly distributed fixtures on the frame that slide along the first linear guide slider pair. A first cylinder drives a push plate to position the aluminum material nearby. A second cylinder drives a clamping block to move along the fifth linear guide slider pair for clamping. This allows the workpiece to be clamped in a single setup to accommodate different widths. Simultaneously, a lifting device driven by a fourth cylinder moves along the seventh linear guide slider pair, eliminating repeated positioning errors, improving the machining accuracy of complex curved surfaces, significantly shortening the clamping stroke, and avoiding accuracy deviations caused by repeated positioning. The dual-axis swing head, with its second swing head rotating around the X-axis and its first swing head rotating around the Z-axis, works in coordination with the Z-axis of the lifting device, the X-axis of the gantry device, and the Y-axis mechanism. Combined with an umbrella-shaped tool magazine integrating multiple milling cutters and one saw blade, the equipment can perform composite processes such as drilling, milling, and cutting in a single operation.

[0023] like Figures 1 to 4 As shown, this embodiment provides a five-axis machining center for aluminum materials, including a frame 1, a limiting device 2, a fixture 3, a tool magazine 4, a dual-axis swivel head 5, a gantry device 6, a Y-axis mechanism 7, and a lifting device 8.

[0024] like Figure 1 As shown, the limiting device 2 is set on both sides of the frame 1. When processing aluminum materials, the limiting device 2 on the nearest side can be selected for positioning. Multiple sets of clamps 3 that slide along the X-axis of the frame 1 are evenly arranged on the upper side of the frame 1. The gantry device 6 includes two columns 23 connected to the side of the frame 1. An X-axis mechanism is set on the column 23, and a Y-axis mechanism 7 is installed on the top of the gantry device 6. A servo motor 24 is also set on the column 23.

[0025] Specifically, such as Figure 2 As shown, two first linear guide slider pairs 9 are distributed in parallel on the upper part of the frame 1 to ensure the sliding stability of the clamp 3; second linear guide slider pairs 11 and third linear guide slider pairs 12 are distributed on both sides of the width direction of the frame 1, and the bottom of the column 23 is connected to the second linear guide slider pairs 11 and third linear guide slider pairs 12 on both sides of the frame 1.

[0026] Specifically, a first rack 10 and a second rack 14 are respectively distributed between the second linear guide slider pair 11 and the third linear guide slider pair 12; the first rack 10 is located in the middle of the second linear guide slider pair 11, and the second rack 14 is located in the middle of the third linear guide slider pair 12, and baffles 13 are provided on both sides of the length direction of the first rack 10 and the second rack 14.

[0027] The servo motor 24 has a transmission gear 26 on its motor shaft that meshes with the first rack 10 and the second rack 14 respectively. The servo motor 24 drives the gear 26 to rotate, thereby realizing the meshing transmission between the gear 26 and the rack. This enables the gantry device 6 to slide along the second linear guide slider pair 11 and the third linear guide slider, and ensures the stability of the gantry device 6.

[0028] The baffles 13 on both sides of the first rack 10 and the second rack 14 along their length direction ensure that the gear 26 does not exceed the length of the rack and disengage from the rack when it is engaged.

[0029] like Figure 2 As shown, the limiting device 2 includes a push plate 17, which is driven by the first cylinder 15 to move up and down on the fourth linear guide slider pair 16. During the processing of aluminum materials, the operator can select the nearest side for positioning according to the position of the workpiece to optimize the process and improve efficiency.

[0030] like Figure 3 As shown, the upper part of the clamp 3 is provided with a fifth linear guide slider pair 21, and the lower part of the clamp 3 is provided with a clamping block 18. The clamping block 18 ensures the stable connection between the clamp 3 and the first linear guide slider pair 9. Sliding blocks 20 are provided at both ends of the fifth linear guide slider pair 21. The sliding blocks 20 are pushed on the fifth linear guide slider pair 21 by the second cylinder 19 to move linearly, which not only improves the flexibility of the operation of the clamp 3, but also ensures the stability and reliability of the clamp 3 during the working process.

[0031] Specifically, the sliding block 20 moves linearly by being pushed by the second cylinder 19; the second cylinder 19, as a power source, can provide a stable and powerful pushing force, enabling the sliding block 20 to move smoothly in a straight line on the fifth linear guide slider pair 21; this ensures the stability and reliability of the fixture 3 during operation, while also greatly improving work efficiency and ease of operation.

[0032] like Figure 4As shown, the gantry device 6 is equipped with a tool magazine 4 and a lifting device 8. The tool magazine 4 is connected to the sixth linear guide slider pair 28 installed on the column 23 of the gantry device 6. The top of the gantry device 6 is also equipped with a Y-axis slide plate 27. The seventh linear guide slider pair 31 is connected to the Y-axis mechanism 7 through the Y-axis slide plate 27. The lifting device 8 is connected to the seventh linear guide slider pair 31. The lifting device 8 is equipped with a Z-axis slide plate 29 and the seventh linear guide slider pair 31. The lower end of the lifting device 8 is equipped with a dual-axis swing head 5. The dual-axis swing head 5 is connected to the Z-axis slide plate 29 and moves up and down along the seventh linear guide slider pair 31. The dual-axis swing head 5 includes a first swing head that rotates around the Z-axis direction of the lifting device 8 and a second swing head that rotates around the X-axis.

[0033] Specifically, the tool magazine 4 includes multiple milling cutters and one saw blade arranged in an umbrella shape. Through the tool magazine 4 designed on the gantry device 6, the number of milling cutters in the tool magazine 4 is no less than eight, and the number of saw blades is no less than one, ensuring high efficiency and precision in both milling and sawing. Combined with the coordinated rotational movement of the second and first swing heads of the dual-axis swing head 5, different surfaces can be processed in a continuous process, thus avoiding the tedious step of manually changing workpieces when processing different surfaces. This greatly improves processing efficiency and precision, enabling high-precision drilling and milling of complex three-dimensional curved surfaces of aluminum materials for doors and windows in a single operation.

[0034] The working principle of this utility model:

[0035] After the aluminum material is placed on the frame 1, the push plate 17 is driven by the first cylinder 15 to move along the fourth linear guide slider pair 16, pushing the aluminum material to the limiting device 2. Then, the clamp 3 slides along the X-axis first linear guide slider pair 9 to both sides of the aluminum material; the second cylinder 19 drives the sliding block 20 to move along the fifth linear guide slider pair 21, cooperating with the fifth stop block 22 to clamp the workpiece.

[0036] The servo motor 24 of the gantry device 6 drives the gear 26 through the reducer 25, which meshes with the rack of the frame 1, causing the whole machine to move along the second linear guide slider pair 11 and the third linear guide slider pair 12.

[0037] Y-axis mechanism 7 drives lifting device 8 to move laterally along the gantry beam. Fourth cylinder 30 drives Z-axis slide plate 29 to move vertically along seventh linear guide slider pair 31. Subsequently, the second swing head of dual-axis swing head 5 rotates around the X-axis of lifting device 8 to adjust the tool tilt angle, and the first swing head rotates 360° around the Z-axis of lifting device 8 to compensate for the direction, so that the tool is always perpendicular to the surface to be machined, realizing one-time drilling and milling of curved surfaces, inclined surfaces, and grooves.

[0038] The tool magazine 4 contains eight pre-installed milling cutters and a saw blade; after milling is completed, the third cylinder drives the saw blade to move along the sixth linear guide slider pair 28 to switch to sawing mode.

[0039] The gantry device 6 drives the saw blade to move along a preset trajectory. The first and second swing heads adjust the saw blade angle in real time to achieve irregular end face cutting.

[0040] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
