Description

Technical Field

[0001] The invention belongs to the technical field of composite honeycomb core materials, and in particular relates to a device and an operating method for chamfering a honeycomb core material. Background Art

[0002] In high-end manufacturing industries such as aviation, aerospace, and automobile manufacturing, composite materials are widely used due to their light weight and high strength. In particular, composite honeycomb cores, as a key component in sandwich structures, have a quality that is directly related to the performance of the final product. However, in the traditional honeycomb core preparation process, there are many shortcomings in cutting using saw blades, which not only affect the quality of the honeycomb core, but also reduce production efficiency.

[0003] First, the traditional saw blade cutting method is prone to deformation and overcutting of the honeycomb core due to the heavy weight of the tool and the strong cutting force, resulting in a large number of burrs on the workpiece surface, which requires subsequent manual trimming, which not only increases labor costs but also prolongs product preparation time. Secondly, due to the large vibration generated during saw blade cutting, it is difficult to ensure cutting accuracy, further increasing the difficulty of repair work. In addition, a large amount of harmful dust is released during the cutting process of the traditional method, which not only pollutes the working environment, but also poses a threat to the health of operators. Finally, the long-term exposure of the honeycomb core during the cutting and repair process may cause additional deformation or breakage, thereby reducing product quality, and may cause the honeycomb core to be contaminated, affecting the smooth progress of subsequent processes.

[0004] In summary, the existing technology has problems such as poor cutting accuracy, poor surface treatment, serious environmental pollution and waste of human resources, which need to be solved urgently to improve the efficiency and quality of composite honeycomb core preparation. Therefore, it is necessary to develop a new chamfering processing device that can overcome the above problems and meet the needs of modern industry for high-quality composite honeycomb cores.

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below. Figures 1 to 4 The embodiment of the present invention provides a device for chamfering a honeycomb core material, comprising: a machine tool body 100 and a support plate 200, wherein the machine tool body 100 is provided with a guide rail 110 and a positioning portion 120; a slider 210 is provided on the support plate 200, and the slider 210 can be slidably connected with the guide rail 110 to fix the support plate 200 to the machine tool body 100; a cutting portion 220 and a feeding portion 230 are provided on the support plate 200, wherein the cutting portion 220 is provided with a tool 223, and the positioning portion 120 is used to fix the workpiece to be processed at the tool setting point of the tool 223; the feeding portion 230 includes a moving portion 231 and a fixing portion 232, wherein the moving portion 231 is provided with a handle 233, and an operator can push the handle 233 to make the support plate 200 move along the guide rail 110 through the slider 210 to form a feeding motion, and an angle dial 234 is provided on the fixing portion 232, and the angle dial 234 is connected to a pointer 240 to indicate the angle between the current tool 223 and the machine tool worktable. By adopting a small-mass high-speed rotating blade, the vibration during cutting is effectively reduced, the cutting accuracy is improved, and the deformation and overcutting problems of the workpiece caused by the traditional saw blade cutting method are avoided, thereby ensuring the consistency and accuracy of the chamfer. Moreover, due to the sharpness and high-speed rotation characteristics of the blade, the surface of the honeycomb core after cutting is smooth and almost burr-free, which greatly reduces the workload of the subsequent finishing process. At the same time, the harmful dust generated by this device during the cutting process is reduced by about 63% compared with the traditional saw blade device, which helps to create a cleaner working environment, protect the health of operators, and is conducive to the dust-free and constant humidity management of the workshop.

[0028] Further, refer to Figure 1, the guide rail 110 provided on the machine tool body 100 ensures that the pallet 200 always maintains a straight line motion during the movement, avoiding cutting errors caused by offset. The slider 210 on the pallet 200 is slidably connected to the guide rail 110, so that the pallet 200 can move accurately along the guide rail 110, ensuring the stability and repeatability of the feeding movement. The cutting part 220 and the feeding part 230 are integrated on the pallet 200, which not only simplifies the structure of the equipment, but also improves the convenience of operation. Furthermore, the positioning part 120 is used to fix the workpiece to be processed at the tool point of the tool 223, ensuring that the starting position of each cutting is consistent, greatly improving the processing accuracy. In addition, the design of the angle dial 234 and the pointer 240 allows the operator to intuitively adjust and read the cutting angle, ensuring that the needs of chamfering at different angles can be met. This design not only improves the quality of chamfering, but also reduces the time of manual adjustment, significantly improving work efficiency.

[0029] Furthermore, the present invention does not limit the specific structure of the positioning part 120. The positioning part 120 is used to fix the workpiece to be processed to the tool point of the tool 223, so as to ensure that the starting position of each cutting is completely consistent. Of course, the present invention does not limit the specific fixing method of the positioning part 120 and the workpiece to be processed. Preferably, the positioning part 120 will cooperate with a tool for fixing the workpiece to be processed such as 3M tape to fix the workpiece to be processed (honeycomb) on the area to be processed. In addition, the design of the angle dial 234 and the pointer 240 allows the operator to intuitively adjust and read the cutting angle, ensuring that the needs of chamfering at different angles can be met. This design not only improves the quality of chamfering, but also reduces the time of manual adjustment, significantly improving work efficiency.

[0030] Further, the support plate 200 is provided with an arc groove 250, a slideway 251 is provided in the arc groove 250, and a first support rod is provided on the angle turntable 234, and the first support rod can pass through the arc groove 250 and be fixed to the support plate 200 through the first fastening nut 260. Further, referring to Figure 2 , a semicircular hole 270 is provided on the support plate 200, and a second support rod is provided on the angle turntable 234. The second support rod can pass through the semicircular hole 270 and be fixed to the support plate 200 through the second fastening nut 280. Furthermore, a cutting section workbench stopper is provided on the angle turntable 234, and the cutting section workbench stopper can be fixed between the angle turntable 234 and the second fastening nut 280. The angle turntable 234 is fixed to the support plate 200 by fixing the first fastening nut 260 and the second fastening nut 280. Furthermore, a cutting section workbench stopper is provided between the second fastening nut 280 and the angle turntable 234. The function of the cutting section workbench stopper is to limit the moving range of the monitoring turntable to prevent it from sliding up and down and deviating from the predetermined position during the processing. Refer to Figure 3, an arc groove 250 and a slideway 251 are arranged on the support plate 200, and a first support rod is arranged on the angle turntable 234, which is fixed to the support plate 200 by a first fastening nut 260, and the second support rod can pass through the semicircular hole 270 and be fixed to the support plate 200 by a second fastening nut 280 to fix the angle turntable 234 on the support plate 200. By setting two fastening nuts, that is, the first fastening nut 260 is located in the arc groove 250, and the second fastening nut 280 is located in the semicircular hole 270, double locking of the angle turntable 234 can be achieved. This design not only improves the fixing effect after the angle is adjusted, but also ensures that the angle turntable 234 will not have any slight displacement or looseness during the processing. Especially in the case of high-speed cutting and long-term continuous processing, any slight angle change may cause burrs or deformation on the surface of the workpiece, affecting the quality of chamfering. Therefore, the double locking design significantly enhances the stability of the angle and ensures the consistent chamfering quality of each workpiece. The design of the arc groove 250 and the semicircular hole 270 provides two independent support points for the angle dial 234. Preferably, the scale range on the support plate 200 is 0° to 90°, so that the angle dial 234 can be accurately adjusted between 0° and 90°. The first fastening nut 260 is located in the arc groove 250, allowing the angle dial 234 to rotate freely within a certain range and be fixed at the desired angle by the fastening nut 260; the second fastening nut 280 is located in the semicircular hole 270, further limiting the movement range of the angle dial 234 to ensure that it will not shift after being fixed. This dual support structure not only improves the accuracy of angle adjustment, but also reduces the angle deviation caused by the loosening of a single fastening point, ensuring that each adjustment can achieve the desired effect.

[0031] Furthermore, the cutting part 220 is also provided with a motor 221 and a motor fixing device 222, the motor fixing device 222 is fixed to the angle turntable 234 by screws, and the motor 221 can be snapped into the motor fixing device 222. The design of the rotational connection with the motor 221 allows the cutter 223 to rotate at a high speed under the drive of the motor 221, thereby achieving efficient cutting. This design not only improves the cutting speed, but also ensures the stability and consistency of the cutting process. The rotational connection between the cutter 223 and the motor 221 adopts a precise mechanical structure, which can transmit sufficient torque to ensure that the cutter 223 remains stable during the cutting process. Especially when processing composite honeycomb cores, the high-speed rotation of the cutter 223 can reduce cutting resistance, reduce the risk of deformation of the workpiece, and improve cutting accuracy. Of course, the present invention does not limit the specific connection mode of the tool 223 and the motor 221. Preferably, the tool 223 can be rotatably connected with the motor 221, and a cutter head fastening bolt is provided between the tool 223 and the motor 221. When the blade is no longer sharp after a long period of processing, the cutter head fastening bolt can be unscrewed to replace the tool 223 to ensure the efficiency of chamfering. Further, a locking device 300 is also provided below the support plate 200, and a handle 310 and a rotating shaft 320 are provided on the locking hand wheel. The handle 310 and the rotating shaft 320 are connected so that the rotating shaft 320 can be locked to the edge of the guide rail 110. This design ensures the absolute stability of the support plate 200 during the processing. The function of the locking device 300 is to press the rotating shaft 320 against the edge of the guide rail 110 by rotating the handle 310 after the support plate 200 reaches the predetermined position, so as to prevent the support plate 200 from being displaced during the processing. This design not only improves the safety of processing, but also ensures the accuracy of cutting. Especially in the high-speed cutting process, any slight displacement may cause burrs or deformation on the workpiece surface, affecting the product quality. Furthermore, an emergency stop button is also provided on the machine tool body 100. The design of setting an emergency stop button on the machine tool body 100 provides safety protection for the operator in emergency situations. The function of the emergency stop button is that when an event that is not in the original processing plan occurs, such as a workpiece stuck, a tool breakage or other dangerous situations, the operator can immediately press the button to directly cut off the power of the machine tool 100 and quickly stop all movements. This design not only protects the personal safety of the operator, but also avoids further damage to the equipment and workpieces.

[0032] Further, refer to Figure 4 The present invention also provides an operating method of a honeycomb core material chamfering device, using any of the above devices, comprising the following steps:

[0033] S1: Loosen the first fastening nut 260 and the second fastening nut 280, adjust the angle dial 234 to rotate it to a corresponding angle, and then tighten the first fastening nut 260 and the second fastening nut 280;

[0034] S2: After confirming that the tool 223 is available, the machine tool body 100 is powered on, and the handle 233 is pushed to push the support plate 200 to the expected starting position;

[0035] S3: The workpiece to be processed is installed and fixed on the positioning part 120, and after routine inspection, the rotation button of the tool 223 is pressed. After the tool 223 reaches a predetermined rotation speed, the support plate 200 is pushed toward the workpiece at a speed of 500 to 3000 mm / min to complete the chamfering;

[0036] S4: After the processing is completed, the stop button of the tool 223 is pressed, and the workpiece can be removed only after the tool 223 stops rotating completely;

[0037] S5: If an event not originally planned occurs during the processing, the emergency stop button can be immediately pressed to directly power off the machine tool 100. This method ensures the efficiency and consistency of chamfering through a series of standardized operating steps. First, the operator needs to adjust the angle dial 234 to the required chamfering angle and fix it by tightening the nut 260 to ensure the accuracy of the angle. Then, after confirming that the tool 223 is available, the machine tool 100 is powered on, and the handle 233 is pushed to push the pallet 200 to the expected starting position to ensure the correctness of the cutting starting point. Then, the workpiece to be processed is installed and fixed on the positioning part 120, and the tool 223 rotation button is pressed after routine inspection. After the tool 223 reaches the predetermined speed, the pallet 200 is pushed to move toward the workpiece at a speed of 500 to 3000 mm / min to complete the chamfering. This standardized operating process not only improves processing efficiency, but also reduces the possibility of human error. Finally, after the processing is completed, the stop button of the tool 223 is pressed, and the workpiece can be removed only after the tool 223 stops rotating completely, ensuring the safety of the operation. In addition, if an event that is not in the original processing plan occurs during the processing, the operator can immediately press the emergency stop button to directly power off the machine tool 100 and quickly stop all movements, thereby protecting the safety of the operator and the equipment. In short, this operation method significantly improves the efficiency and safety of chamfering processing and ensures high-quality product output.
