Description

Technical Field

[0001] This application relates to the field of aviation aluminum processing equipment, and in particular to a three-axis loop cutting machine for processing aviation aluminum. Background Art

[0002] The three-axis loop cutting machine for processing aviation aluminum is a high-precision equipment specially used for processing aviation aluminum. Aviation aluminum has the characteristics of light weight and high strength and is widely used in the aerospace field. The three-axis loop cutting machine realizes the fine cutting of aviation aluminum through the precise movement of three axes, namely X, Y, and Z, in combination with a loop cutting wire.

[0003] The existing aviation aluminum cutting machines usually consist of a machine tool main body, a three-axis motion system, a cutting wire, a driving system, etc. The three-axis motion system drives the workpiece to move on the machine tool main body, and then the driving system drives the cutting wire to move, so as to perform cutting processing on the workpiece.

[0004] Currently, the processing of aviation aluminum usually involves the integrated cutting of aluminum on an unprocessed plate according to processing requirements by the cutting wire. The remaining aluminum after cutting is still sleeved on the finished workpiece. Moreover, because the aluminum usually processed has a large mass, it takes a long time for the staff to take out the processed finished product, thus affecting the processing efficiency of aluminum. Summary of the Invention

[0005] In order to further improve the processing efficiency of aviation aluminum, this application provides a three-axis loop cutting machine for processing aviation aluminum.

[0006] The three-axis loop cutting machine for processing aviation aluminum provided by this application adopts the following technical solutions: A three-axis loop cutting machine for processing aviation aluminum, comprising a workbench, a positioning drive assembly, and a cutting assembly. The positioning drive assembly is installed on the workbench and is used for clamping and driving the workpiece to move. The cutting assembly includes a limiting frame, a driving member, a cutting wire, a pushing cylinder, and a pushing rod. The limiting frame is installed on the workbench through the driving member. The cutting wire is installed on the limiting frame and is used for processing the workpiece. The pushing cylinder is installed on the limiting frame. The pushing rod is slidably connected to the limiting frame and is connected to the piston rod of the pushing cylinder. The pushing rod can move vertically under the drive of the piston rod of the pushing cylinder.

[0007] By adopting the above technical solution, the positioning and driving assembly installed on the workbench fixes the workpiece and drives the workpiece to move, adjusts the workpiece to a suitable processing position. The cutting wire is installed on the limit frame, and the driving part drives the limit frame to move, so that the cutting wire cuts the workpiece. At the same time, through the cooperation between the positioning and driving assembly and the driving part, the processed waste after cutting is cut into smaller blocks, and then the pushing cylinder drives the pushing rod to move, and the pushing rod pushes out the smaller block processed waste after cutting, so that the staff can directly take out the processed product, thereby further improving the processing efficiency of aluminum materials.

[0008] In a specific feasible implementation, the driving part includes a first driving motor, a first driving gear and a first limit rack. The first driving motor is installed on the limit frame, the first driving gear is installed on the output shaft of the first driving motor and is coaxially installed with the output shaft, and the first limit rack is installed on the workbench and is installed along the X-axis of the workbench.

[0009] By adopting the above technical solution, the cooperation of the first driving motor, the first driving gear and the first limit rack enables the limit frame to move accurately along the X-axis direction of the workbench. This design not only improves the positioning accuracy of the cutting assembly, but also ensures the stability of the aviation aluminum material during the processing process, thereby improving the cutting quality. In addition, this solution effectively reduces the material waste caused by position deviation and further improves the processing efficiency.

[0010] In a specific feasible implementation, the pushing rod is set as a U-shaped block, a limit plate is installed on the limit frame, limit sleeves are correspondingly arranged on both sides of the limit plate for the pushing rod, both ends of the pushing rod are respectively slidably connected in the limit sleeves on both sides, the pushing cylinder is installed on the limit plate and is located between the two side rods of the pushing rod, and the piston rod of the pushing cylinder is fixedly connected to the middle part of the pushing rod.

[0011] By adopting the above technical solution, setting the pushing rod as a U-shaped block can effectively increase the contact area between the pushing rod and the processed waste and improve the pushing efficiency. The limit sleeves arranged on both sides of the limit plate slidably connect both ends of the pushing rod to ensure the stability of the pushing rod when moving in the vertical direction and avoid deviation. The pushing cylinder is installed on the limit plate and is fixedly connected to the middle part of the pushing rod through the piston rod, so that the pushing rod can move smoothly in the vertical direction under the drive of the pushing cylinder, thereby efficiently pushing out the processed waste, reducing the manual cleaning time and improving the processing efficiency.

[0012] In a specific feasible implementation, the positioning and driving assembly includes a positioning frame, a second driving motor, a second driving gear, a second limiting rack, and a positioning disk. The positioning frame is slidably connected to the workbench. The second driving motor is installed on the positioning frame. The second driving gear is installed on the output shaft of the second driving motor. The second limiting rack is installed on the workbench and is installed along the Y-axis direction of the workbench. The second driving gear is meshed with the second limiting rack. The positioning disk is installed on the positioning frame. The positioning disk is set as a magnetic chuck, and the workpiece is fixed through a magnetic adsorption structure.

[0013] By adopting the above technical solution, the second driving motor drives the second driving gear to rotate, and then the second driving gear cooperates with the second limiting rack installed on the workbench, so as to drive the positioning frame to move along the Y-axis direction of the workbench, and then drive the positioning disk installed on the positioning frame to move along the Y-axis direction. The adsorption structure on the positioning disk can firmly fix the workpiece, ensure that the workpiece remains stable during the processing, avoid the decline of processing accuracy caused by vibration or movement, further improve the positioning accuracy and stability of the workpiece on the three-axis circular cutting machine, and then improve the processing quality of the aviation aluminum material.

[0014] In a specific feasible implementation, it further includes a rotating motor. The rotating motor is installed on the positioning frame. The positioning disk is installed on the output shaft of the rotating motor.

[0015] By adopting the above technical solution, the addition of the rotating motor enables the positioning disk to perform a rotating motion under the drive of the rotating motor. This can not only adjust the processing angle of the workpiece to meet the multi-angle processing requirements, but also improve the processing flexibility and adaptability. Combining with the moving function of the positioning frame, the rotating motor further enhances the spatial operation ability of the equipment, providing strong support for the precision processing of complex aviation aluminum materials.

[0016] In a specific feasible implementation, a keyway is opened on the lower end surface of the positioning disk. A spline shaft is installed on the output shaft of the rotating motor. The spline shaft is slidably connected in the keyway, so that the positioning disk is slidably connected to the output shaft of the rotating motor. A support member is installed on the output shaft of the rotating motor. The support member is used to support the positioning disk.

[0017] By adopting the above technical solution, the sliding connection structure between the positioning disk and the output shaft of the rotating motor can realize the flexible adjustment of the positioning disk in the axial direction. The cooperation between the keyway and the spline shaft ensures the stability of the positioning disk during rotation. At the same time, the setting of the buffer effectively reduces the impact of the vibration generated during the processing on the positioning disk, thereby improving the processing accuracy and extending the service life of the equipment.

[0018] In a specific feasible implementation scheme, the support member includes a support spring and a support ring. The support ring is provided in two groups. The two groups of support rings are respectively installed on the output shaft of the rotating motor and the lower bottom surface of the positioning plate. The support spring is installed between the two groups of support rings, and the two ends of the support spring are respectively fixedly connected to the support rings at the upper and lower ends. The positioning plate is slidably connected to the output shaft of the rotating motor.

[0019] By adopting the above technical solution, the positioning plate and the output shaft of the rotating motor are flexibly connected through the support spring and the support ring. The support spring can provide a buffering effect when the positioning plate is impacted or vibrated, effectively reducing the vibration amplitude of the positioning plate, thereby improving the stability during the processing. In addition, the design of the support spring can also compensate for the slight displacement of the positioning plate during the rotation process, ensuring that the positioning plate always maintains accurate positioning, thereby improving the processing accuracy of aviation aluminum.

[0020] In a specific possible implementation scheme, it also includes a material guide box, the workbench is provided with a plurality of material passing holes, the plurality of material passing holes are evenly distributed, the material guide box is installed under the workbench, the material guide box is arranged in a bucket shape, a material collection bin is installed at the lowest end of the material guide box, and a material discharge port is opened on the side wall of the material collection bin.

[0021] By adopting the above technical solution, the material guide box is installed directly below the workbench, and a plurality of corresponding material passing holes are opened on the workbench. The cutting waste generated during the workpiece processing can pass through the material passing holes into the material guide box, and slide along the side wall of the material guide box into the collecting bin for collection and storage, thereby realizing the automatic collection and orderly management of waste, improving the cleaning efficiency of the equipment, reducing the workload of manual cleaning, and avoiding the influence of waste accumulation on the processing process, thereby improving the overall efficiency of aviation aluminum processing and the cleanliness of the environment.

[0022] In a specific possible implementation scheme, an inclined slide is installed on the workbench located on one side of the moving direction of the driving member, and the inclined slide is used to guide and collect the processing waste pushed out by the push rod.

[0023] By adopting the above technical solution, the inclined slide is installed on the workbench on the side of the moving direction of the driving part. When the pushing cylinder drives the pushing rod to move downward and drives the limit frame to move through the driving part, the pushing rod pushes the small cutting fragments formed by cutting in the direction of the inclined slide, and slides along the inclined slide and collects them, thereby reducing the frequency and workload of manual cleaning and improving the overall processing efficiency. At the same time, it can avoid the waste of waste materials, recycle the waste materials, facilitate subsequent processing or recycling, reduce resource waste, and improve the environmental protection performance of the equipment.

[0024] In a specific possible implementation scheme, a plurality of ball and socket structures are provided on the workbench, and balls are installed in the ball and socket structures.

[0025] By adopting the above technical solution, multiple sets of ball socket structures are arranged on the workbench and balls are installed therein, which can significantly reduce the friction between the workpiece and the workbench surface during the processing, thereby improving the smoothness of the workpiece movement. This design not only helps to reduce the wear of the workpiece surface, but also improves the processing accuracy and efficiency.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the material pushing cylinder and the material pushing rod, the cut finished workpiece can be automatically separated from the remaining aluminum material and pushed out, significantly reducing the manual operation time and improving the processing efficiency; 2.

Detailed Description of the Invention

[0031] The embodiment of the present application discloses a three-axis loop cutting machine for processing aviation aluminum materials.

[0032] As Figure 1 shown, the three-axis loop cutting machine for processing aviation aluminum materials includes a workbench 1, a positioning drive assembly 2 and a cutting assembly 3. A plurality of brackets are installed on the lower end surface of the workbench 1, and the workbench 1 is supported on the ground through the plurality of brackets. The positioning drive assembly 2 and the cutting assembly 3 are both installed on the workbench 1, and the positioning drive assembly 2 and the cutting assembly 3 can move perpendicular to each other on the workbench 1.

[0033] The cutting assembly 3 includes a limit frame 31, a driving member 32, a cutting wire 33, a material pushing cylinder 34 and a material pushing rod 35. A first guide rail is installed on the workbench 1, and the first guide rail is installed along the X-axis direction of the limit frame 31. A slider of the limit frame 31 is installed on the limit frame 31, and the slider of the limit frame 31 is slidably connected to the first guide rail, so that the limit frame 31 is slidably connected to the workbench 1. The driving member 32 includes a first driving motor 321, a first driving gear 322 and a first limit rack 323. The first limit rack 323 is arranged on the workbench 1 along the installation direction of the first guide rail. The first driving motor 321 is installed on the limit frame 31, the first driving gear 322 is installed on the output shaft of the first driving motor 321, and the first driving gear 322 is meshed with the first limit rack 323. By driving the first driving gear 322 to rotate through the first driving motor 321, since the first driving gear 322 is meshed with the first limit rack 323, the first limit rack 323 limits the first driving gear 322, so as to drive the limit frame 31 to move in the reverse direction of the X-axis of the workbench 1.

[0034] The workpiece is fixed and driven to move by the positioning and driving assembly 2 installed on the workbench 1, and the workpiece is adjusted to a suitable processing position. The cutting wire 33 is installed on the limit frame 31, and the driving member 32 drives the limit frame 31 to move, so that the cutting wire 33 cuts the workpiece. At the same time, through the cooperation between the positioning and driving assembly 2 and the driving member 32, the processed waste after cutting is cut into smaller blocks, and then the material pushing cylinder 34 drives the material pushing rod 35 to move, and the material pushing rod 35 pushes out the smaller block-shaped processed waste after cutting, so that the staff can directly take out the processed product, thereby further improving the processing efficiency of aluminum materials.

[0035] The limit frame 31 is set as a U-shaped frame, and the two side walls of the limit frame 31 are respectively located at the upper and lower ends of the workbench 1. The cutting wire 33 is installed on the limit frame 31, and both ends of the cutting wire 33 are fixedly connected to the two side walls of the limit frame 31 respectively. A wire passing groove is formed on the workbench 1 corresponding to the cutting wire 33, and the cutting wire 33 passes through the wire passing groove, so as to prevent the workbench 1 from interfering with the movement of the cutting wire 33. A limit plate is installed on one side wall of the limit frame 31. The material pushing rod 35 is preferably set as a U-shaped rod. Limit sleeves are installed on both sides of the limit plate, and the two side rods of the material pushing rod 35 are respectively slidably connected to the limit sleeves on both sides. The material pushing cylinder 34 is installed on the limit plate, and the piston rod of the material pushing cylinder 34 is fixedly connected to the middle part of the material pushing rod 35. At the same time, since the material pushing rod 35 is set as a U-shaped rod, it can ensure good contact between the material pushing rod 35 and the waste, thereby further improving the material pushing effect. At the same time, the limit sleeves can effectively limit the movement track of the material pushing rod 35 and prevent it from deviating during the pushing process. The material pushing cylinder 34 can be a single-acting cylinder or a multi-stage cylinder, which is specifically determined according to the thrust requirement.

[0036] The pusher rod 35 is set as a U-shaped block, which can effectively increase the contact area between the pusher rod 35 and the processing waste, and improve the pushing efficiency. The limiting sleeves arranged on both sides of the limiting plate are slidably connected to both ends of the pusher rod 35 to ensure the stability of the pusher rod 35 when moving in the vertical direction and avoid deviation. The pusher cylinder 34 is installed on the limiting plate and is fixedly connected to the middle part of the pusher rod 35 through a piston rod, so that the pusher rod 35 can move smoothly in the vertical direction under the drive of the pusher cylinder 34, thereby efficiently pushing out the processing waste, reducing the manual cleaning time, and improving the processing efficiency.

[0037] As Figure 2 shown, the positioning drive assembly 2 includes a positioning frame 21, a second drive motor 22, a second drive gear 23, a second limit rack 24 and a positioning disk 25. A second guide rail is installed on the workbench 1 along the Y-axis direction. A positioning frame 21 slider is installed on the positioning frame 21, and the positioning frame 21 slider is slidably connected to the second guide rail, so that the positioning frame 21 is slidably connected to the workbench 1, and at the same time, the positioning frame 21 can be driven to move along the Y-axis direction of the workbench 1.

[0038] The second drive motor 22 drives the second drive gear 23 to rotate, and then through the cooperation between the second drive gear 23 and the second limit rack 24 installed on the workbench 1, the positioning frame 21 is driven to move along the Y-axis direction of the workbench 1, so as to drive the positioning disk 25 installed on the positioning frame 21 to move along the Y-axis direction. The adsorption structure on the positioning disk 25 can firmly fix the workpiece, ensure the stability of the workpiece during the processing, avoid the decline of the processing accuracy caused by vibration or movement, further improve the positioning accuracy and stability of the workpiece on the three-axis circular cutting machine, and thus improve the processing quality of the aviation aluminum material.

[0039] As Figure 3 shown, in the embodiment of the present application, a rotating motor 4 is further included. The rotating motor 4 is installed on the positioning frame 21, the output shaft of the rotating motor 4 is arranged along the Z-axis direction of the workbench 1, a spline shaft is installed on the output shaft of the rotating motor 4, a keyway is installed on the lower plate surface of the positioning plate, the keyway corresponds to the spline shaft, the spline shaft is inserted into the keyway, and the positioning disk 25 can slide relative to the spline shaft, so that the positioning disk 25 is slidably connected to the rotating motor 4, and the positioning disk 25 can be driven to rotate by the rotating motor 4. A support member 5 is installed on the output shaft of the rotating motor 4, and the support member 5 is used to provide a supporting force for the positioning disk 25.

[0040] The addition of the rotating motor 4 enables the positioning disk 25 to perform a rotating motion driven by the rotating motor 4. This can not only adjust the machining angle of the workpiece to meet the multi-angle machining requirements, but also improve the machining flexibility and adaptability. Combining with the moving function of the positioning frame 21, the rotating motor 4 further enhances the spatial operation ability of the equipment, providing strong support for the precision machining of complex aviation aluminum materials.

[0041] An adsorption structure for fixing the workpiece is installed on the positioning disk 25, and the adsorption structure can be a vacuum adsorption device. The vacuum adsorption device fixes the workpiece by evacuating the air, thus effectively ensuring the stability of the workpiece during the machining process.

[0042] The support member 5 includes a support ring 51 and a support spring 52. There are two groups of support rings 51, and the two groups of support rings 51 are respectively installed on the output shaft of the rotating motor 4 and the lower end face of the positioning disk 25.
