Description

Technical Field

[0001] The present invention relates to the technical field of aircraft processing, in particular to a cutting device for processing a metal casing of a low-altitude aircraft. Background Art

[0002] In the processing of low-altitude aircraft metal casings, cutting is a key process that directly affects the dimensional accuracy, connection strength and subsequent assembly quality of the casing. Currently, the cutting equipment used in the industry for low-altitude aircraft metal casing processing is mostly based on traditional laser cutting machines, supplemented by simple fixtures to form a processing system. These existing equipment can meet the initial processing requirements in terms of basic cutting functions, that is, to achieve separation and cutting of metal materials through the high temperature effect of the laser beam. However, the existing technology has many defects in practical applications:

[0003] Existing equipment is not capable of collecting and treating pollutants such as smoke, exhaust gas and tiny particles generated during the cutting process. Most equipment lacks an effective negative pressure collection device or is only equipped with a simple exhaust structure, making it difficult to achieve real-time and efficient collection of pollutants. This not only deteriorates the working environment quality and endangers the health of operators, but also causes pollutants to adhere to the internal precision components of the laser cutting machine, causing erosion and damage to the equipment, shortening the equipment's service life and affecting the stable and efficient cutting work.

[0004] Furthermore, there are obvious shortcomings in the grinding process after cutting. Existing equipment often needs to transfer the cut workpiece to special grinding equipment for subsequent processing. The process connection is cumbersome, which reduces the overall processing efficiency. Even if some equipment integrates simple grinding functions, there are problems of incomplete and uneven grinding. The movement mode of the grinding parts is single, and it is impossible to fully cover the inner and outer walls of the workpiece cutting. There is a lack of effective auxiliary means to remove surface burrs, oxide layers and other impurities, making it difficult to ensure the flatness and smoothness after grinding. At the same time, the debris and grinding chips generated during the grinding process are easy to adhere to the workpiece or grinding parts, further affecting the grinding effect and efficiency, and cannot meet the needs of high-precision processing scenarios of low-altitude aircraft metal casings.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Combination Figures 1-8 As shown, the present invention provides a technical solution: a cutting device for processing a metal casing of a low-altitude aircraft, comprising a chassis 1, a processing component 4 and a control component 2 are respectively provided on both sides of the surface of the chassis 1, and a cutting component 3 for cutting a workpiece is provided on one side of the control component 2;

[0029] The cutting assembly 3 includes a fixed base 31 fixedly mounted on the chassis 1, a movable frame 32 rotatably connected to the fixed base 31, one end of the movable frame 32 movably connected to a first cylinder 33 rotatably mounted on the chassis 1, and the other end of the movable frame 32 rotatably connected to an adjusting rod 34, the adjusting rod 34 being threadedly connected to a movable base 35 slidably mounted on the movable frame 32, and a laser cutting machine 36 fixedly mounted on the movable base 35;

[0030] A collecting box 37 is fixedly installed on one side of the surface of the chassis 1, and a first connecting pipe 38 is provided on the top of the collecting box 37. The other end of the first connecting pipe 38 is connected to a telescopic hose 39, and the other end of the telescopic hose 39 is connected to a second connecting pipe 310. The other end of the second connecting pipe 310 is connected to a bent pipe 311, and the other end of the bent pipe 311 is connected to an absorption pipe 312, and the position of the absorption pipe 312 corresponds to that of the laser cutting machine 36. A fixed box 313 is fixedly installed on the bottom of the movable seat 35, and a motor group 314 is provided on the fixed box 313. The output end of the motor group 314 is fixedly connected to a fan 315 rotatably installed in the bent pipe 311.

[0031] In an embodiment of the present invention, by starting the first cylinder 33, the piston rod of the first cylinder 33 performs telescopic movement, thereby driving the movable frame 32 to rotate around its hinge point on the fixed base 31. Since the laser cutting machine 36 is fixedly mounted on the movable frame 32, the rotation of the movable frame 32 will synchronously drive the laser cutting machine 36 to rotate toward the side where the workpiece is located. This rotation method can accurately adjust the height distance between the laser cutting machine 36 and the workpiece to meet the height parameter requirements of different cutting processes. At the same time, the operator can manually rotate the adjusting rod 34. The adjusting rod 34 converts the rotational motion into the linear motion of the movable base 35 through the threaded transmission between it and the movable base 35, thereby driving the movable base 35 and the laser cutting machine 36 fixed on the movable base 35 to move up and down in the vertical direction. Through this up and down movement operation, the relative position relationship between the laser cutting machine 36 and the workpiece in the horizontal direction can be further flexibly adjusted to ensure that the laser cutting machine 36 can accurately cut the workpiece;

[0032] By turning on the motor group 314, the fan 315 can be driven to rotate. When the fan 315 rotates at a high speed, a negative pressure environment will be formed in the bend pipe 311 and the entire air flow channel. Since the positions of the absorption pipe 312 and the laser cutting machine 36 correspond to each other, under the action of the negative pressure, the smoke, exhaust gas, small particles and other pollutants generated by the laser cutting machine 36 in the process of cutting the material will be quickly sucked into the absorption pipe 312 along the direction of the air flow. After these pollutants enter the absorption pipe 312, they will pass through the bend pipe 311, the second connecting pipe 310, the telescopic hose 39 and the first connecting pipe 38 in sequence, and finally be transported to the collection box 37. The collection box 37 is usually provided with a gas filter. The filter device or specific containing structure can effectively intercept and collect the incoming pollutants to prevent them from spreading into the surrounding environment again. As the motor group 314 continues to operate, the fan 315 continuously generates negative pressure, so that the entire air flow circulation continues, so that the pollutants generated in the working area of ​​the laser cutting machine 36 can be collected into the collection box 37 in real time and efficiently, effectively improving the environmental quality when the laser cutting machine is working, reducing the harm of pollutants to the health of operators, and also avoiding the erosion and damage of pollutants to the precision components inside the laser cutting machine, thereby extending the service life of the equipment and ensuring the stability and efficiency of laser cutting work.

[0033] Example 2: Combination Figure 4 As shown, on the basis of embodiment one, the control component 2 includes a fixing frame 21 fixedly mounted on the chassis 1, a driving motor 22 is fixedly mounted on the outer wall of the fixing frame 21, a sleeve 23 is rotatably mounted on one side of the fixing frame 21, and the sleeve 23 is connected to the output end of the driving motor 22 through a synchronous pulley transmission member 24, and a synchronous pulley transmission member 24 is fixedly mounted on one end of the sleeve 23.

[0034] In an embodiment of the present invention, in the workpiece processing process, the workpiece is first passed through the center position of the sleeve 23 and the chuck 25 in a precise positioning manner. The chuck 25 has a reliable clamping function. Through its internal clamping mechanism, such as the radial movement of the claws, a uniform and sufficient clamping force is applied to the workpiece, thereby firmly clamping the workpiece in a predetermined position to ensure that the workpiece will not be displaced or loosened during subsequent processing, providing a basic guarantee for high-precision processing. When the drive motor 22 is turned on, the drive motor 22 starts to work as the power source of the entire rotating system, and its output end rotates according to the set speed and direction. The output torque is transmitted through the synchronous pulley transmission member 24, and the synchronous pulley transmission member 24 is composed of a driving pulley, a driven pulley and a synchronous belt. The driving pulley is installed at the output end of the driving motor 22, and the driven pulley is installed on the sleeve 23. During the transmission process, the synchronous belt and the pulley rely on tooth engagement to avoid slipping, and can accurately transmit the rotational motion and power of the driving motor 22 to the sleeve 23. After receiving the rotational power, the sleeve 23 drives the chuck 25 rigidly connected to it to rotate together. Since the chuck 25 has firmly clamped the workpiece, the workpiece will also rotate synchronously with the sleeve 23 and the chuck 25, forming a stable rotation processing system. At this time, the cutting component 3 cuts the workpiece in a rotating state according to the pre-set processing parameters and procedures.

[0035] Example 3: Combination Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, on the basis of the second embodiment, the processing component 4 includes a mounting base 41 mounted on the chassis 1, a servo motor 42 is fixedly mounted on the top of the mounting base 41, a rotating disk 43 is fixedly connected to the output end of the servo motor 42, a central shaft 44 is fixedly mounted at the axis of the rotating disk 43, an outer shaft 45 is fixedly mounted at a position deviated from the center of the rotating disk 43, and a grinding piece 46 is provided at the end of the central shaft 44 and the outer shaft 45.

[0036] The grinding member 46 includes a fixed rod 47 fixedly mounted on the end of the central shaft 44, the other end of the fixed rod 47 being slidably connected to a telescopic rod 48, a second cylinder 423 being fixedly mounted on both sides of the fixed rod 47, the output end of the second cylinder 423 being fixedly connected to the outer wall of the telescopic rod 48, a transverse plate 49 being fixedly mounted on both sides of the telescopic rod 48, a surface grinding member 410 being rotatably connected to the transverse plate 49, and an end grinding member 411 for grinding the end of the workpiece being provided between the two surface grinding members 410;

[0037] A rotating shaft 412 is rotatably connected to the horizontal plate 49, and a surface grinding piece 410 is fixedly mounted on the rotating shaft 412. A first bevel gear 414 is fixedly mounted on the inner side of the rotating shaft 412, and a grinding motor 413 is provided at one end of the rotating shaft 412. A third cylinder 424 is fixedly mounted inside the telescopic rod 48, and a spline rod 425 is rotatably connected to the output end of the third cylinder 424. The other end of the spline rod 425 is fixedly connected to the end grinding piece 411. A sleeve rod 426 is slidably connected to the outer wall of the spline rod 425, and the sleeve rod 426 is rotatably mounted on the telescopic rod 48. The outer wall of the sleeve rod 426 is fixedly connected to a second bevel gear 427 meshing with the first bevel gear 414.

[0038] The horizontal plate 49 is slidably connected to a movable frame 415 in the vertical direction. Gear rods 416 are fixedly installed on both sides of the inner wall of the movable frame 415. A half gear 417 is fixedly connected to the outer wall of the rotating shaft 412 and meshes with the gear rods 416. Knocking rods 418 are slidably connected to both sides of the horizontal plate 49. The outer walls of the two knocking rods 418 are fixedly connected to mounting brackets 419, and the mounting brackets 419 are fixedly connected to the outer wall of the movable frame 415. A damping spring 420 is provided on one side of the mounting bracket 419 and is sleeved on the knocking rods 418.

[0039] A positioning frame 428 is sleeved on the outer wall of the central axis 44, and the positioning frame 428 is fixedly mounted on the rotating disk 43. The outer wall of the positioning frame 428 is rotatably connected to a driven gear 429, and the surface of the driven gear 429 is provided with an arc groove 432 in a circumferential array. An adjusting motor 430 is fixedly mounted on one side of the positioning frame 428, and the output end of the adjusting motor 430 is fixedly connected to a driving gear 431 meshing with the driven gear 429. The positioning frame 428 is slidably connected to a sliding rod 433 in a circumferential array, and the end of the sliding rod 433 is fixedly connected to a guide rod 434, and the inner end of the guide rod 434 is slidably mounted in the arc groove 432, and the outer end of the sliding rod 433 is fixedly connected to an arc block 435.

[0040] In the embodiment of the present invention, after the cutting work is completed, the two parts of the workpiece are separated, that is, the distance between the two workpieces is adapted to the specifications of the end grinding piece 411, and the two parts of the workpiece are fixed and positioned. The preliminary positioning of the partial grinding assembly is achieved by turning on the second cylinder 423. The second cylinder 423 serves as a linear motion actuator, and the telescopic movement of its piston rod drives the telescopic rod 48 to move linearly. Since the cross plate 49 is fixedly connected to the telescopic rod 48, and the surface grinding piece 410 and the end grinding piece 411 are installed on the cross plate 49, the movement of the telescopic rod 48 will drive the cross plate 49, the surface grinding piece 410 and the end grinding piece 411 to move linearly. The end grinding piece 411 moves synchronously, so that the surface grinding piece 410 accurately contacts the end of the workpiece, providing an initial position guarantee for the subsequent grinding operation, and then the third cylinder 424 is turned on. The third cylinder 424 also serves as a linear motion actuator. The extension and contraction of its piston rod drives the spline rod 425 to move linearly. The end grinding piece 411 is installed on the spline rod 425, so the movement of the spline rod 425 will make the end grinding piece 411 accurately located between the cutting points of the two workpieces after cutting, so as to meet the demand for grinding the cut surface. Then the grinding motor 413 is turned on. The grinding motor 413 serves as a power source, and its output shaft drives the rotation The shaft 412 rotates synchronously, and the rotating shaft 412 is fixedly connected to the surface grinding member 410 and the first bevel gear 414, so it will drive the surface grinding member 410 and the first bevel gear 414 to rotate synchronously. The first bevel gear 414 and the second bevel gear 427 are meshed with each other. The rotation of the first bevel gear 414 will drive the second bevel gear 427 to rotate. The second bevel gear 427 is connected to the spline rod 425 through a spline, thereby transmitting power to the spline rod 425 and the end grinding member 411, so that the end grinding member 411 also rotates synchronously. At this time, the rotating surface grinding member 410 can grind the outer wall of the workpiece, and the end grinding member 411 is 1 can grind the inner wall and cutting surface of the workpiece. In addition, the servo motor 42 is turned on. The servo motor 42 serves as the power source for the rotational motion. Its output shaft drives the rotating disk 43 to rotate. The central shaft 44 and the outer shaft 45 are installed on the rotating disk 43. Therefore, they rotate synchronously with the rotating disk 43. The central shaft 44 and the outer shaft 45 respectively drive the corresponding grinding members 46 to rotate, so that the surface grinding member 410 and the end grinding member 411 perform circular motion while rotating themselves. This composite motion mode enables the grinding members to perform comprehensive and uniform grinding on the inner and outer walls of the cut portion of the workpiece, thereby improving the grinding quality and efficiency.

[0041] And when the rotating shaft 412 rotates, it can drive the half gear 417 to rotate synchronously. When the half gear 417 rotates, it can cooperate with the gear rods 416 meshing on both sides to drive the movable frame 415 to move back and forth, so that the elastic force of the damping spring 420 can make the movable frame 415 drive the mounting frame 419 and the knocking rod 418 to move back and forth, so that the knocking rod 418 knocks the workpiece out, so that it can cooperate with the surface grinding piece 410 and the end grinding piece 411 to knock the workpiece during grinding. During the grinding process, when the surface grinding piece 410 and the end grinding piece 411 perform conventional grinding operations on the workpiece, the reciprocating knocking action of the knocking rod 418 can cause the workpiece to vibrate slightly. This vibration helps to break the stress concentration area on the surface of the workpiece caused by grinding, so that the grinding agent is more evenly distributed on the surface of the workpiece, so that the surface grinding piece 410 can remove the roughness on the surface of the workpiece more comprehensively and evenly. The end grinding piece 410 and the end grinding piece 411 are respectively used to grind the end of the workpiece and the polishing part 411. The polishing part 410 is used to grind the end of the workpiece and the polishing part 411 is used to grind the end of the workpiece. The polishing part 410 is used to grind the end of the workpiece and the polishing part 41 ...
