Description

Technical Field

[0001] This invention relates to the field of aluminum alloy casting processing equipment, and in particular to a multi-directional automatic cutting device and cutting system. Background Technology

[0002] With the development of lightweight automotive demand, automotive parts originally made of cast iron or cast steel are gradually being replaced by lightweight aluminum alloy castings. Aluminum castings are generally made by pouring molten aluminum. After the aluminum casting is cast, the gate will be connected to the aluminum casting. Therefore, in order to facilitate the subsequent processing of the aluminum casting, a cutting machine is needed to cut the aluminum casting from the gate.

[0003] Existing cutting machines mostly employ simple mechanical cutting tools, such as saw blades or cutters, and use electric motors, hydraulic systems, or pneumatic power sources to drive the tools in reciprocating or rotary motion to cut off the gate. For example, some small, traditional cutting machines use a motor to rotate a saw blade, utilizing the saw blade's cutting action to cut off the gate. Furthermore, the positioning and clamping of these machines are relatively simple, typically employing manual positioning or simple mechanical positioning devices, such as positioning slots or blocks. Clamping devices are generally manual or semi-automatic fixtures, such as pressure plates or clamps, which are manually operated to secure the aluminum alloy casting and prevent movement during the cutting process. This type of cutting machine has the following drawbacks in practical applications: (1) Low cutting accuracy: Manual positioning and manual clamping methods make it difficult to guarantee the accuracy and consistency of positioning each time, which can easily lead to deviation in the cutting position. Moreover, factors such as vibration and wear of the cutting tool during the cutting process will also affect the cutting accuracy, resulting in an uneven cutting surface and potentially leaving a large amount of gate allowance, which requires further processing.

[0004] (2) Low production efficiency: Traditional cutting machines can usually only cut the gates of aluminum alloy castings one by one, and cannot achieve batch or continuous operation; in addition, manual loading, unloading, positioning and clamping operations are time-consuming, labor intensity is high, fatigue is easy to occur, which affects work efficiency and product quality, making it difficult to meet the needs of large-scale production.

[0005] (3) Poor adaptability: Existing cutting machines are generally designed for specific types or sizes of aluminum alloy casting gates. For gates of different shapes, sizes and structures, different cutting tools or fixtures need to be replaced, and even the equipment needs to be adjusted and modified, resulting in poor flexibility and versatility.

[0006] (4) Low level of automation: It lacks automated detection, monitoring and feedback mechanisms, cannot monitor parameters and product quality in real time during the cutting process, and cannot automatically adjust the cutting process according to the actual situation, which easily leads to scrap and defective products.

[0025] The following is in conjunction with the appendix Figure 1-10The present invention will provide a more detailed description of an embodiment of a multi-directional automatic cutting device and cutting system.

[0026] A multi-directional automatic cutting device, such as Figure 3 , 4 As shown, the system includes a workbench 1 and a cutting robot 2 mounted on one side of the workbench 1. The workbench 1 is equipped with a five-axis rotary mechanism 3, and a positioning and clamping assembly 4 is fixedly connected to the five-axis rotary mechanism 3. The five-axis rotary mechanism 3 includes an angle adjustment component 31 and a rotary component 32. The rotary component 32 is mounted on the angle adjustment component 31. The angle adjustment component 31 is used to drive the rotary component 32 and the positioning clamping component 4 to achieve multi-angle tilt adjustment. One end of the rotary component 32 is connected to the angle adjustment component 31, and the other end is connected to the positioning clamping component 4 for transmission. The cutting robot 2 includes a base 21 and a multi-axis drive arm 22 mounted on the base 21. One end of the multi-axis drive arm 22 is fixed to the base 21, and the other end is connected to a connecting seat 23. The connecting seat 23 is connected to a cutting component 5 and a milling component 6 respectively. The cutting component 5 is used to cut off the gate, and the milling component 6 is used to remove burrs. The cutting component 5 and the milling component 6 are arranged perpendicular to each other and are both connected to the connecting seat 23 via an electric spindle 24.

[0027] Specifically, the angle adjustment component 31 enables the rotation component 32 and the positioning clamping component 4 to achieve multi-angle tilt adjustment. The rotation component 32, in turn, drives the positioning clamping component 4 to rotate 360 ​​degrees, allowing the aluminum casting fixed on the positioning clamping component 4 to be flexibly adjusted to any processing angle in space. This allows the cutting robot 2 to perform precise cutting operations on the aluminum casting from different directions. Simultaneously, the five-axis rotation mechanism 3, through the coordinated operation of the angle adjustment component 31 and the rotation component 32, effectively expands the processing orientation range of the aluminum casting, improves the flexibility and adaptability of the cutting process, and meets the process requirements of multi-directional cutting of complex aluminum castings.

[0028] In this embodiment, as Figure 7 , 8 As shown, the angle adjustment assembly 31 includes a fixed base 311, an indexing plate 312, a five-axis base plate 313, and a drive motor 314. The fixed base 311 is fixed to the workbench 1, and the indexing plate 312 is symmetrically arranged on the fixed base 311. One side of the indexing plate 312 is connected to a turntable 315, and the other side is connected to a rotary distributor 316. The five-axis base plate 313 has a U-shaped structure, and both ends of the five-axis base plate 313 are rotatably connected to the turntable 315. The drive motor 314 is arranged on the indexing plate 312, and its output end is connected to the turntable 315 for transmission.

[0029] Specifically, when the drive motor 314 starts, its output drives the turntable 315 to rotate. Through the rotational connection between the turntable 315 and the two ends of the five-axis base plate 313, the five-axis base plate 313 is driven to perform multi-angle tilt adjustments around the axis of the indexing plate 312. The indexing plate 312 precisely controls the tilt angle of the five-axis base plate 313, while the rotary distributor 316 ensures stable transmission of hydraulic oil or signals during angle adjustment, guaranteeing the stability and accuracy of the angle adjustment assembly 31. The U-shaped design of the five-axis base plate 313 not only provides a stable support platform for the installation of the rotating assembly 32 but also effectively avoids interference with other components during movement, further improving the smoothness of the mechanism's operation.

[0030] It should be noted that the drive motor 314 drives the turntable 315 to rotate through the gear transmission structure in the indexing plate 312, thereby enabling the five-axis base plate 313, which is fixedly connected to the turntable 315, to adjust the pitch angle around the central axis of the indexing plate 312. The adjustment range can be set by the program according to the actual processing requirements, and can generally achieve multi-angle tilt from 0 to 90 degrees.

[0031] In this embodiment, as Figure 8 As shown, the rotating assembly 32 includes a rotating table 321, a rotating motor 322, and an oil circuit distributor 323. The rotating table 321 is fixed on the five-axis base plate 313. The rotating motor 322 is located on one side of the rotating table 321, and its output end is connected to the rotating table 321 for driving the rotating table 321 to rotate. The oil circuit distributor 323 is located at the bottom of the rotating table 321 and is connected to the external hydraulic system 11 through a pipeline for controlling the rotation angle. A baffle 324 is provided between the rotating table 321 and the positioning and clamping assembly 4.

[0032] Specifically, when the rotary motor 322 starts, its output shaft drives the worm gear structure inside the rotary table 321 through a coupling, causing the rotary table 321 to rotate continuously or in increments 360 degrees relative to the five-axis base plate 313. The oil circuit distributor 323 controls the on / off state and flow rate of hydraulic oil, working in conjunction with the rotary motor 322 to achieve precise control of the rotation angle of the rotary table 321, meeting the requirements of high-precision machining. The baffle 324 is made of high-strength alloy material, effectively preventing debris generated during machining from splashing into the rotating assembly 32, avoiding wear on precision components such as gears and bearings, and extending the service life of the equipment.

[0033] In this embodiment, as Figure 7 and Figure 9As shown, the positioning and clamping assembly 4 includes a fixed plate 41, a positioning block 42, and a cylinder clamp 43; the positioning block 42 is located on the top two sides of the fixed plate 41 and is provided with positioning pins 421; multiple sets of cylinder clamps 43 are provided on the fixed plate 41 along the diagonal direction, and the output end of the cylinder clamp 43 is provided with a clamping block 431; the fixed plate 41 is also provided with a receiving block 44, the top of the receiving block 44 is inclined along the direction of the positioning block 42, and is used to cooperate with the clamping block 431 to clamp the aluminum casting.

[0034] Specifically, when the aluminum casting is placed on the fixed plate 41, the positioning pin 421 on the positioning block 42 inserts into the pre-set positioning hole in the aluminum casting, achieving initial positioning. Subsequently, the cylinder clamp 43 is activated, controlling the clamping block 431 to move towards the aluminum casting, cooperating with the receiving block 44 to form a stable clamping of the aluminum casting. The inclined design of the receiving block 44 can adapt to the bottom structure of aluminum castings of different shapes, ensuring that the aluminum casting is subjected to uniform force during clamping and avoiding workpiece deformation due to excessive local pressure. Multiple sets of cylinder clamps 43 are distributed along the diagonal, which can fix the aluminum casting from multiple directions, further improving the stability and reliability of clamping and meeting the strict requirements of high-precision cutting processing for workpiece positioning.

[0035] In this embodiment, as Figure 10 As shown, the cutting assembly 5 includes a cutting handle 51 and a saw blade 52. One end of the cutting handle 51 is rotatably connected to the electric spindle 24, and the other end is fixed to the saw blade 52. The milling assembly 6 includes a hydraulic handle 61 and a milling cutter 62. One end of the hydraulic handle 61 is drive-connected to the electric spindle 24, and the other end is fixed to the milling cutter 62.

[0036] Specifically, the cutting shank 51 is made of high-strength alloy steel, possessing excellent rigidity and wear resistance. It effectively transmits the torque of the electric spindle 24 and reduces vibration during the cutting process. The saw blade 52 is made of ultra-fine grain cemented carbide, with staggered saw teeth and special edge strengthening treatment, enabling high-speed and efficient cutting of aluminum casting gates, producing a smooth, burr-free cut. The hydraulic shank 61 clamps the milling cutter 62 through hydraulic expansion, providing high clamping force and precision, effectively preventing displacement of the milling cutter 62 during high-speed rotation. The milling cutter 62 is made of integral cemented carbide, with a rationally designed helix angle and excellent chip removal performance. It can quickly remove burrs remaining on the surface of the aluminum casting and gate after cutting, significantly improving the surface quality of the workpiece.

[0037] In this embodiment, as Figure 5As shown, the workbench 1 includes a frame 101 and protective covers 102 located on both sides of the frame 101; a feeding trough 103 is provided on the frame 101 for discharging cutting waste and aluminum casting workpieces; a chip removal mechanism 7 is provided below the feeding trough 103 for automatically separating the chips and gates generated during processing and discharging them separately; a dust discharge port 104 is provided on the protective cover 102, and a dust removal mechanism 8 is connected to the outside of the dust discharge port 104 for absorbing the dust generated during the cutting and deburring process.

[0038] Specifically, the frame 101 is welded from square tubing, providing a stable structure capable of withstanding various impacts during processing. The protective cover 102 is composed of a transparent acrylic sheet and a metal frame, facilitating operator observation of the processing while effectively preventing debris and dust from spilling out. The width and depth of the feed chute 103 are designed based on the dimensions of the aluminum casting and the volume of processing waste, ensuring that waste and workpieces can smoothly slide into the chip removal mechanism 7. The dust discharge ports 104 are located on the top and sides of the protective cover 102, forming a multi-point dust collection layout to maximize the capture of dust generated during processing.

[0039] In this embodiment, as Figure 1 , 2 As shown, the chip removal mechanism 7 includes a conveyor belt 71, a screening assembly 72, and a collection box 73; the conveyor belt 71 has a Z-shaped structure, with one end extending to the bottom of the work platform 1; the screening assembly 72 is located on the inclined section of the conveyor belt 71, and the screening assembly 72 has multiple layers of screens inside; the collection box 73 is located below the screening assembly 72 and is used to collect the separated waste chips.

[0040] Specifically, the conveyor belt 71 is made of wear-resistant rubber with anti-slip textures on the surface, effectively conveying processing waste and workpieces. The screening assembly 72 contains multiple layers of screens with apertures arranged from largest to smallest. When waste and workpieces enter the screening assembly 72 along the conveyor belt 71, smaller debris passes through the screens and falls into the collection box 73, while larger pieces of material continue to be conveyed along the conveyor belt 71 to their designated location, achieving automatic separation of waste and workpieces. The collection box 73 is equipped with casters at the bottom for easy periodic cleaning of waste by operators.

[0041] In this embodiment, as Figure 1 As shown, the dust removal mechanism 8 includes a vacuum cleaner 81 and a dust collection pipe 82. One end of the dust collection pipe 82 is connected to the vacuum cleaner 81, and the other end is connected to the dust discharge port 104.

[0042] Specifically, the vacuum cleaner 81 uses a high-power centrifugal fan with strong suction, capable of drawing dust from inside the protective cover 102 through the dust collection pipe 82. The dust collection pipe 82 is made of wear-resistant flexible hose and can be flexibly arranged according to the position of the protective cover 102. The air outlet of the vacuum cleaner 81 is equipped with a high-efficiency filter device, which can purify the intake air, reduce dust pollution to the environment, and protect the health of the operator.

[0043] In this embodiment, as Figure 10 As shown, the multi-directional cutting device also includes a tool magazine mechanism 9, which is located on one side of the cutting robot 2 and is used to store cutting components 5 and milling components 6 of different specifications. The tool magazine mechanism 9 includes a tool magazine frame 91 and multiple tool holder seats 92. The tool magazine frame 91 has a stepped structure, and the tool holder seats 92 are equidistantly arranged on the top of the tool magazine frame 91 and are provided with a locking component 93 for installing tools. A photoelectric sensor 94 is provided on one side of the locking component 93 for detecting tools.

[0044] Specifically, the tool magazine 91 adopts a stepped layout design, which can store different models of cutting components 5 and milling components 6 in layers according to tool specifications and usage frequency, improving tool changing efficiency. The locking component 93 of the tool holder 92 achieves quick locking through the engagement of spring-loaded jaws with the annular groove on the tool holder, ensuring that the coaxiality error of the tool after installation does not exceed 0.02mm. The photoelectric sensor 94 detects the presence of a tool in the tool holder 92 by emitting an infrared beam. When a tool is detected as missing or in an abnormal position, it immediately sends a signal to the electronic control system 12, triggering an alarm and pausing the machining process to prevent machining failures or product quality defects caused by tool problems. The locking component 93 adopts a jaw-type structure for locking with the tool holder, preventing the tool from loosening or falling off. The inner side of the jaw is equipped with a wear-resistant rubber pad, which can increase the friction between the jaw and the tool holder, improve clamping stability, and avoid damage caused by rigid contact between the jaw and the tool holder. When a tool needs to be changed, the electric spindle 24 drives the current tool to the corresponding tool holder 92 position. The clamping jaws of the clamping assembly 93 open under hydraulic drive. After the tool is fully inserted, the jaws close to complete the fixation. The entire tool changing process is automatically controlled by the electronic control system 12, which effectively improves the continuity of machining.

[0045] A cutting-off system, such as Figure 1 , 2 As shown, including Multi-directional automatic cutting device; Soundproof room 10 is composed of multiple soundproof panels and is used to house the multi-directional automatic cutting device and isolate processing noise. The hydraulic system 11 is located outside the soundproof room 10 and is connected to the cutting robot 2 and the five-axis rotating mechanism 3 via hydraulic pipelines to provide power. The electrical control system 12 is electrically connected to the five-axis rotary mechanism 3, the cutting robot 2, the chip removal mechanism 7, and the dust removal mechanism 8, and is used to control the operation of the entire cutting process.

[0046] Specifically, the electrical control system 12 includes an electrical control cabinet and a controller. The electrical control cabinet and controller are located outside the soundproof room 10 and are electrically connected. The controller uses a PLC control system, which can achieve automated control of various actuators through preset programs, including angle adjustment of the five-axis rotary mechanism 3, rotation of the rotary component 32, clamping action of the positioning clamping component 4, multi-axis linkage of the cutting robot 2, and coordinated operation of the chip removal and dust removal mechanism 8. Simultaneously, the controller also has a human-machine interface, allowing operators to perform parameter settings, program calls, status monitoring, and fault alarms via a touchscreen, facilitating real-time monitoring of equipment operation and flexible adjustments.

[0047] The processing flow of the above cutting system is as follows: System startup and self-test: Start the electrical control system 12, and the system enters the self-test mode to detect the working status of each module, such as the cutting robot, the tool magazine mechanism 9, the five-axis rotation mechanism 3, and the hydraulic system 11, to ensure that each component is operating normally.

[0048] Tool selection and clamping: The electronic control system 12 sends instructions to the cutting robot according to the preset machining parameters. The cutting robot moves to the designated position in the tool magazine, grabs the appropriate tool, and clamps the tool on the electric spindle 24 to complete the tool preparation.

[0049] Workpiece positioning and clamping: The production line robot grabs the aluminum alloy casting to be processed and places it on the positioning and clamping assembly 4; the electrical control system 12 controls the hydraulic system 11 to start, assisting the positioning and clamping assembly 4 to complete the precise clamping of the workpiece, ensuring that the workpiece does not shift during the processing.

[0050] Machining posture adjustment: The five-axis rotary mechanism 3 drives the workpiece or electric spindle 24 to flexibly adjust the posture according to the machining requirements, so that the tool and the machining surface are at the optimal machining angle to meet the multi-directional machining requirements.

[0051] Cutting and deburring operations: The electric spindle 24 drives the cutting tool to rotate at high speed to cut off the gate of the aluminum alloy casting, and then completes the deburring process of the product; during the operation, the dust collector 81 starts simultaneously to remove the generated dust in real time; the automatic separation chip removal structure works continuously to automatically separate the chips from the gate and discharge them separately.

[0052] Work completion and cycle: After processing is completed, the cutting robot 2 returns the cutting tool to the designated position of the tool magazine mechanism 9; the hydraulic system 11 is depressurized, the positioning and clamping assembly 4 is released, and the production line robot takes away the processed product; the electrical control mechanism controls the system to enter the next workpiece cycle processing, or shuts down the system according to the instruction to realize automated continuous operation.

[0053] Working principle of the invention: In the actual processing, the aluminum casting is first fixed by the positioning and clamping assembly 4. The production line robot places the aluminum casting on the fixed plate 41, and the positioning pin 421 on the positioning block 42 achieves initial positioning. Then, the cylinder clamp 43 is activated, and the clamping block 431 at its output end cooperates with the receiving block 44 to apply clamping force to the aluminum casting from the diagonal direction, ensuring that the aluminum casting will not be displaced during processing. Next, the electrical control system 12 controls the five-axis rotary mechanism 3 to start working according to the preset processing parameters. Among them, the drive motor 314 in the angle adjustment assembly 31 drives the turntable 315 to rotate, which drives the five-axis base plate 313 to rotate around the index. The tilt angle of the disc 312 is adjusted, and the rotary motor 322 of the rotating component 32 drives the rotary table 321 to rotate. Combined with the precise control of the rotation angle by the oil circuit distributor 323, the aluminum casting on the positioning clamping component 4 is adjusted to the optimal processing position. Finally, the cutting robot 2 retrieves the cutting component 5 or milling component 6 of the corresponding specification and size from the tool magazine mechanism 9 according to the processing requirements. The multi-axis transmission arm 22 of the cutting robot 2 drives the cutting component 5 or milling component 6 to move to the processing position according to the instructions. The electric spindle 24 drives the saw blade 52 or the milling cutter 62 to rotate at high speed to cut off the pouring gate of the aluminum casting or to mill the burrs.

[0054] During processing, debris and waste materials fall into the chip removal mechanism 7 through the feed chute 103 of the workbench 1. The conveyor belt 71 transports the waste materials to the screening component 72 for separation, and the waste chips fall into the collection box 73. Larger gate waste materials are discharged from the end of the conveyor belt 71. At the same time, the dust removal mechanism 8 continuously absorbs dust from the processing area through the dust discharge port 104 to ensure a clean working environment. If it is necessary to change the tool, the cutting robot 2 can move to the tool magazine mechanism 9 to automatically change the cutting component 5 or milling component 6 of the required specifications. The entire processing is carried out in a soundproof room 10, which effectively reduces noise pollution. The hydraulic system 11 provides stable power to each actuator, and the electrical control system 12 coordinates the operation of all mechanisms. The entire processing flow realizes automated and intelligent control, effectively improving the accuracy, efficiency and safety of aluminum casting cutting processing.
