Description

Technical Field

[0001] This invention belongs to the technical field of digital engraving of energy beams for aircraft sheet metal skin, specifically relating to a method for adjusting the energy beam path that passes through a five-axis oscillating head. Background Technology

[0002] The aircraft skin digital profiling equipment is used for digital profiling of aircraft sheet metal skin. Its core mechanism involves clamping the aircraft skin using a flexible clamping system and then machining it with a five-axis machine tool. This machining process is non-contact, meaning it is completed through ablation using an energy beam. Because it is a five-axis machine tool, it includes an AC tilting head. The energy beam is transmitted via a special reflective surface, making it a flight-like transmission method. The transmission path must pass through the tilting head, meaning it is transmitted internally to the machining head. This method is concealed and saves external space.

[0003] However, since the A-axis and C-axis of the AC oscillating head are constantly rotating during processing, it is crucial to ensure that the energy beam maintains a precise and constant transmission path as the AC oscillating head rotates. Even a slight deviation in any part of the transmission path will directly lead to an unstable transmission path and extremely large errors at the end, resulting in highly irregular and inconsistent errors in the processed skin parts. Ultimately, this will compromise the accuracy and quality of aircraft skin processing. Therefore, high-precision calibration of the transmission path is essential. Calibrating this energy beam after passing through the AC oscillating head is extremely difficult, and there is an urgent need for methods to achieve high-precision calibration to ensure the processing accuracy of aircraft skin parts.

[0004] Therefore, this invention discloses a method for adjusting the energy beam path through a five-axis oscillating head. Summary of the Invention

[0005] This invention discloses a method for adjusting the energy beam path through a five-axis oscillating head, which can accurately adjust the energy beam processed by the digital engraving equipment for aircraft skin, thereby ensuring the final skin processing accuracy.

[0006] This invention is achieved through the following technical solution: A method for adjusting the energy beam path through a five-axis oscillating head, the five-axis oscillating head including mutually perpendicular A-axis and C-axis, the C-axis being parallel to the machine tool Z-axis, a machining head mounted on the A-axis that rotates with the A-axis, and an energy beam emitter arranged on the axis of the machine tool Z-axis; comprising the following steps: Step 1: Disassemble the A-axis and C-axis. The energy beam emitter emits energy beams along the Z-axis of the machine tool at the highest and lowest positions, respectively. The energy beams pass through the cross-shaped obstruction and then enter the dominant test paper. The direction of the energy beam is adjusted based on the shadow formed on the dominant test paper after being irradiated by the energy beam, until the shadows formed on the dominant test paper by the energy beams emitted by the energy beam emitter at the highest and lowest positions of the machine tool Z-axis completely overlap. Step 2: Install the A-axis and C-axis onto the Z-axis of the machine tool. Arrange a first reflective surface at the bottom of the Z-axis of the machine tool so that the energy beam is reflected by the first reflective surface and emitted along the X-axis of the machine tool. Arrange a cross-shaped obstruction on the X-axis of the machine tool. Emits energy beams along the X-axis direction at the far end and near end of the X-axis of the machine tool so that the energy beams are incident on the visible test paper after passing through the cross-shaped obstruction. Adjust the pose of the first reflective surface based on the shadow formed by the visible test paper after being irradiated by the energy beams until the shadows formed by the energy beams emitted by the energy beam emitters at the far end and near end of the X-axis of the machine tool on the visible test paper completely overlap. Step 3: Set the visible test paper at the same height on the first side of the first reflective surface, and rotate synchronously with the C-axis. Rotate the C-axis and emit energy beams when the C-axis is at different rotation angles. Keep the direction of the energy beam emitter's emission axis parallel to the machine tool's Z-axis. Adjust the position of the energy beam emitter in the horizontal plane so that the shadows formed by the energy beams emitted when the C-axis is at different rotation angles on the visible test paper overlap. Step 4: Set the second reflective surface at the same height as the position of the visible test paper on the first side of the first reflective surface, so that the energy beam is emitted parallel to the Z-axis of the machine tool after being emitted through the second reflective surface. Set the visible test paper on a horizontal plane perpendicular to the direction of energy beam emission. The energy beam emitter emits energy beams along the Z-axis of the machine tool at the highest and lowest positions of the machine tool. Adjust the pose of the second reflective surface until the shadows formed by the energy beams emitted by the energy beam emitter at the highest and lowest positions of the machine tool Z-axis on the visible test paper completely overlap. Step 5: Set a fourth reflective surface below the first reflective surface at the intersection of the A-axis and the C-axis, and set a third reflective surface at the same height and parallel to the first side of the fourth reflective surface; rotate the A-axis and C-axis to 0°, and adjust the pose of the third and fourth reflective surfaces until the energy beams emitted by the energy beam emitter at the highest and lowest positions of the machine tool Z-axis are reflected by the third and fourth reflective surfaces and then emitted to overlap with the shadows formed by the visible test paper; Step 6: Install the machining head on the A-axis. Place an adjustable focusing lens inside the output end of the machining head. Arrange masking tape on the horizontal surface below the machining head. Position the A-axis at 0°. Place the C-axis at the first and second corners, with a 180° interval between the first and second corners. When the C-axis is at the first corner, move the energy beam emitter along the X-axis or Y-axis of the machine tool to obtain a first corner mark on the masking tape. When the C-axis is at the second corner, move the energy beam emitter along the X-axis or Y-axis of the machine tool to obtain a second corner mark on the masking tape. Adjust the orientation of the focusing lens relative to the horizontal surface until the first and second corner marks coincide. Step 7: Rotate the A-axis and C-axis to different angle combinations and emit energy beams under different angle combinations. Place paper tape at the emission end of the energy beam. Determine whether the energy beam is affected by the rotation of the A-axis and C-axis based on the fine holes formed by the energy beam on the paper tape. If it is determined that the energy beam is affected by the rotation of the A-axis and C-axis, repeat steps 1-6 above until it is determined that the energy beam is not affected by the rotation of the A-axis and C-axis. If it is determined that the energy beam is not affected by the rotation of the A-axis and C-axis, the energy beam path adjustment is completed.

[0007] To better realize the present invention, step 1 further includes: Step 1.1: Make the emission axis of the energy beam emitter parallel to the Z-axis of the machine tool, disassemble the A-axis and C-axis, and the energy beam emitter emits an energy beam along the Z-axis of the machine tool; Step 1.2: Set the detection tube coaxially within the allowable range of coaxiality error on the emission path of the energy beam. Inside the detection tube, a cross-shaped obstruction is set between the incident end and the exit end. A visible test paper is set at the exit end of the detection tube. Step 1.3: Raise the energy beam emitter along the Z-axis of the machine tool to the lowest position of the Z-axis, so that the energy beam forms a four-petal shadow on the visible test paper after passing through the cross-shaped obstruction. Adjust the pose of the energy beam emitter until the four petal shadows are equal in size. Step 1.4: Keep the position of the detection tube unchanged, raise the energy beam emitter along the Z-axis of the machine tool to the highest position of the Z-axis of the machine tool and emit the energy beam so that the energy beam forms a four-petal shadow on the visible test paper after passing through the cross-shaped obstruction. Compare the difference between the four-petal shadow formed by the energy beam emitter at the lowest position of the Z-axis of the machine tool and the highest position of the lowest position of the Z-axis of the machine tool. Step 1.5: Repeat steps 1.1-1.4 above until the two four-lobed shadows formed on the visible test paper by the energy beam emitted from the lowest position of the machine tool's Z-axis completely overlap.

[0008] To better realize the present invention, step 2 further includes: Step 2.1: Install the A-axis and C-axis onto the Z-axis of the machine tool, and adjust the A-axis and C-axis to 0° so that the A-axis is parallel to the X-axis of the machine tool and the C-axis is parallel to the Z-axis of the machine tool. Arrange the first reflecting surface at the bottom of the Z-axis of the machine tool. Step 2.2: Set up a detection tube on the emission path of the energy beam after reflection by the first reflecting surface. The axis of the detection tube is parallel to the X-axis of the machine tool. Inside the detection tube, a cross-shaped obstruction is set between the incident end and the emission end. A visible test paper is set at the emission end of the detection tube, and the surface of the visible test paper is perpendicular to the X-axis of the machine tool. Step 2.3: The energy beam emitter emits an energy beam to form a four-lobed shadow on the dominant test paper. The pose of the first reflective surface is adjusted until the four lobed shadows are of equal size. Step 2.4: Emits an energy beam at the near end of the X-axis of the machine tool, keeping the first reflector pose unchanged and the detection cylinder axis parallel to the X-axis of the machine tool. Move the position of the detection cylinder until the four petal shadows formed on the visible test paper after the energy beam passes through the detection cylinder are of equal size. Step 2.5: Emits an energy beam at the far end of the X-axis of the machine tool, keeping the pose of the first reflecting surface and the pose of the detection cylinder unchanged, so that the energy beam forms a four-petal shadow on the visible test paper; compare the difference between the two four-petal shadows formed by the energy beam emitter at the far end of the X-axis of the machine tool and at the near end of the X-axis of the machine tool. Step 2.6: Repeat steps 2.1-2.5 above until the two four-lobed shadows formed by the energy beam emitter at the far end position and the near end position of the X-axis of the machine tool completely overlap.

[0009] To better realize the present invention, step 3 further includes: Step 3.1: Place a visible test paper that rotates synchronously with the C-axis at the same height on the first side of the first reflective surface, and remove the detection tube; Step 3.2: After adjusting the C-axis to the 0° position, emit an energy beam to form a first circular shadow on the dominant test paper; after adjusting the C-axis to the 180° position, emit an energy beam to form a second circular shadow on the dominant test paper; compare the difference between the first and second circular shadows. Step 3.3: Keep the direction of the energy beam emitter's emission axis parallel to the machine tool's Z-axis, and adjust the position of the energy beam emitter in the horizontal plane until the first circular shadow and the second circular shadow completely overlap. Step 3.4: After adjusting the C-axis to 90°, emit the energy beam to form a third circular shadow on the dominant test paper; after adjusting the C-axis to 270°, emit the energy beam to form a fourth circular shadow on the dominant test paper; compare the differences between the third and fourth circular shadows. Step 3.5: Keep the energy beam emitter's emission axis parallel to the machine tool's Z-axis, and adjust the energy beam emitter's position in the horizontal plane until the third circular shadow and the fourth circular shadow completely overlap. Step 3.6: After adjusting the C-axis to 0°, 90°, 180° and 270° in sequence, emit the energy beam. Repeat steps 3.1 to 3.5 above until the four circular shadows formed by the energy beam on the dominant test paper completely overlap.

[0010] To better realize the present invention, step 4 further includes: Step 4.1: Set the second reflector at the same height and parallel to the first side of the first reflector so that the energy beam is emitted parallel to the Z-axis of the machine tool after being emitted through the second reflector, and set the visible test paper on the horizontal plane perpendicular to the direction of energy beam emission. Step 4.2: The energy beam emitter emits an energy beam at the lowest position of the machine tool's Z-axis, causing the energy beam to form a first circular shadow on the visible test paper after being reflected sequentially by the first and second reflective surfaces; the energy beam emitter emits an energy beam at the highest position of the machine tool's Z-axis, causing the energy beam to form a second circular shadow on the visible test paper after being reflected sequentially by the first and second reflective surfaces; compare the differences between the first and second circular shadows. Step 4.3: Adjust the pose of the second reflective surface until the first circular shadow and the second circular shadow completely overlap.

[0011] To better realize the present invention, step 5 further includes: Step 5.1: Set a fourth reflective surface below the first reflective surface at the intersection of the A-axis and the C-axis; set a third reflective surface at the same height and parallel to the first side of the fourth reflective surface; and arrange the dominant test paper on the horizontal surface below the fourth reflective surface. Step 5.2: Rotate the A-axis and C-axis to 0°. The energy beam emitter emits an energy beam at the lowest position of the machine tool's Z-axis, causing the energy beam to be reflected sequentially by the first, second, third, and fourth reflecting surfaces, forming a first circular shadow on the visible test paper. The energy beam emitter then emits an energy beam at the highest position of the machine tool's Z-axis, causing the energy beam to be reflected sequentially by the first, second, third, and fourth reflecting surfaces, forming a second circular shadow on the visible test paper. Compare the differences between the first and second circular shadows. Step 5.3: Adjust the pose of the third reflective surface until the first circular shadow and the second circular shadow completely overlap; Step 5.4: Install the machining head on the A-axis, and set a focusing lens with adjustable position inside the output end of the machining head so that the energy beam is reflected by the fourth reflecting surface and then enters the machining head. Step 5.5: Place paper tape at the output end of the processing head, rotate the A-axis so that the A-axis is at three positions of 90°, 0° and -90° respectively to emit energy beams to form three fine holes on the paper tape, and adjust the pose of the third reflective surface until the three fine holes are completely overlapped. Step 5.6: Disassemble the processing head, place a visible test paper on the horizontal plane below the fourth reflective surface, and emit an energy beam at the lowest position of the machine tool's Z-axis to form a first circular shadow on the visible test paper; emit an energy beam at the highest position of the machine tool's Z-axis to form a second circular shadow on the visible test paper; compare the difference between the first and second circular shadows. Step 5.7: Adjust the pose of the fourth reflective surface until the first circular shadow and the second circular shadow completely overlap.

[0012] To better realize the present invention, step 6 further includes: Step 6.1: Install the machining head on the A-axis, set a focusing lens that can adjust the position inside the output end of the machining head, and place paper tape on the horizontal surface below the machining head; Step 6.2: Rotate the A-axis to 0° and the C-axis to 0°, and move the energy beam emitter along the positive direction of the X-axis of the machine tool to obtain the first scribe line on the paper tape; rotate the A-axis to 0° and the C-axis to 180°, and move the energy beam emitter in the reverse direction along the X-axis of the machine tool to obtain the second scribe line on the paper tape, and compare the overlap between the first scribe line and the second scribe line; Step 6.3: Adjust the position of the focusing lens relative to the horizontal plane until the first and second graduation lines completely coincide. Step 6.4: Rotate the A-axis to 0° and the C-axis to 90°, and move the energy beam emitter along the positive direction of the Y-axis of the machine tool to obtain the third scribe line on the paper tape; rotate the A-axis to 0° and the C-axis to 270°, and move the energy beam emitter in the reverse direction along the Y-axis of the machine tool to obtain the fourth scribe line on the paper tape, and compare the overlap between the third scribe line and the fourth scribe line; Step 6.5: Adjust the position of the focusing lens relative to the horizontal plane until the third and fourth graduation lines completely coincide.

[0013] To better realize the present invention, step 7 further includes: Step 7.1: Keep the A-axis at -90°, rotate the C-axis to 0°, 90°, 180°, and 270° in sequence, and then emit the energy beam. Place the paper tape horizontally below the fourth reflector and check whether the four holes formed in sequence on the paper tape overlap. If they overlap, proceed to step 7.2. Step 7.2: Keep the A-axis at 0°, rotate the C-axis to 0°, 90°, 180° and 270° in sequence and then emit the energy beam. Place the paper tape horizontally below the fourth reflector and check whether the four holes formed in sequence on the paper tape overlap. If they overlap, proceed to step 7.3. Step 7.3: Keep the A-axis at 90°, rotate the C-axis to 0°, 90°, 180°, and 270° in sequence, and then emit the energy beam. Place the paper tape horizontally below the fourth reflector and check whether the four holes formed in sequence on the paper tape overlap. If they overlap, proceed to step 7.4. Step 7.4: Repeat steps 7.1-7.3 above to obtain a total of twelve holes on the paper tape. Check whether the twelve holes overlap. If they overlap, the energy beam path adjustment is completed. If they do not overlap, adjust the energy beam transmission path and repeat steps 1-6 until the twelve holes overlap.

[0014] To better realize the present invention, furthermore, during the twelve energy beam emission processes, if there are any cases where there are no fine holes on the paper tape, the energy beam transmission path is re-checked and adjusted until fine holes appear on the paper tape.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The present invention uses a combination of a detection tube and visible paper, as well as perforation of paper tape, to mark and display the energy beam, effectively solving the problem of the energy beam not being able to be displayed, and making the energy beam calibration process simple and easy; (2) The present invention determines whether the energy beam is parallel to the Z-axis by emitting petal-shaped shadows at the high and low ends of the machine tool Z-axis, and determines whether the energy beam is parallel to the X-axis after passing through the first reflecting surface by emitting petal-shaped shadows at the far and near ends of the machine tool X-axis. The direction adjustment of the energy beam is clearly marked, which solves the problem of the difficulty in determining the direction adjustment of the energy beam. (3) This invention establishes a basis for judging whether the energy beam coincides with the C-axis and a specific adjustment basis by directly forming a circular shadow on the visible paper with the energy beam and by arranging the visible paper at the second reflective surface, comparing the shadows at the C-axis positions of 0° and 180°, 90° and 270°, and simultaneously comparing the shadows at the four positions of 0°, 180°, 90° and 270°, thus solving the problem of difficulty in judging and adjusting the coincidence of the energy beam and the C-axis. (4) The present invention uses paper tape to emit energy beams at the nozzle of the processing head, so that the A-axis is located at three typical positions of 90°, 0° and -90° respectively, forming three fine holes on the paper tape. By comparing whether the three fine holes overlap, the method of judging whether the energy beam reflected by the third reflective surface overlaps with the A-axis axis is not abstract and is visualized, making the process simple and fast. (5) The present invention determines whether the energy beam coincides with the C-axis of the machine tool after passing through the focusing lens by scribing lines on the paper tape along the X-axis of the machine tool when the C-axis is 0° and 180° respectively; and by scribing lines on the paper tape along the Y-axis of the machine tool when the C-axis is 90° and 270° respectively. This method makes it quick and simple to determine whether the final energy beam coincides with the C-axis. (6) This invention further simplifies and quickly examines whether the energy beam is affected by the rotation of the A-axis and C-axis by detecting whether the fine holes formed by the paper tape at the nozzle end of the energy beam overlap at twelve typical positions formed by rotating the A-axis and C-axis to different angles. At the same time, it provides a good method and applicable means for subsequent rapid examination of whether there are problems with the energy beam path. Attached Figure Description

[0018] Example 1: This embodiment discloses a method for adjusting the energy beam path through a five-axis oscillating head, such as... Figures 1-3As shown, the five-axis oscillating head includes mutually perpendicular A-axis and C-axis, with the C-axis parallel to the machine tool's Z-axis. A machining head 5, which rotates along the A-axis, is mounted on the A-axis. An energy beam emitter is arranged on the axis of the machine tool's Z-axis. The process includes the following steps: Step 1: Disassemble the A-axis and C-axis. The energy beam emitter emits energy beams along the Z-axis of the machine tool at the highest and lowest positions, respectively. The energy beams pass through the cross-shaped obstruction and then enter the dominant test paper. The direction of the energy beam is adjusted based on the shadow formed on the dominant test paper after being irradiated by the energy beam, until the shadows formed on the dominant test paper by the energy beams emitted by the energy beam emitter at the highest and lowest positions of the machine tool Z-axis completely overlap. Step 2: Install the A-axis and C-axis onto the Z-axis of the machine tool. Arrange the first reflective surface 1 at the bottom of the Z-axis of the machine tool so that the energy beam is reflected by the first reflective surface 1 and emitted along the X-axis of the machine tool. Arrange a cross-shaped obstruction on the X-axis of the machine tool. Emit the energy beam along the X-axis direction at the far end and near end of the X-axis of the machine tool so that the energy beam enters the visible test paper after passing through the cross-shaped obstruction. Adjust the pose of the first reflective surface 1 based on the shadow formed by the visible test paper after being irradiated by the energy beam until the shadows formed by the energy beam emitted by the energy beam emitter at the far end and near end of the X-axis of the machine tool on the visible test paper completely overlap. Step 3: Set a visible test paper at the same height on the first side of the first reflective surface 1, which rotates synchronously with the C-axis. Rotate the C-axis and emit energy beams when the C-axis is at different rotation angles. Keep the direction of the energy beam emitter's emission axis parallel to the machine tool's Z-axis. Adjust the position of the energy beam emitter in the horizontal plane so that the shadows formed by the energy beams emitted when the C-axis is at different rotation angles on the visible test paper overlap. Step 4: Set the second reflective surface 2 at the same height as the position of the visible test paper on the first side of the first reflective surface 1, so that the energy beam is emitted parallel to the Z-axis of the machine tool after being emitted through the second reflective surface 2. Set the visible test paper on a horizontal plane perpendicular to the direction of energy beam emission. The energy beam emitter emits energy beams along the Z-axis of the machine tool at the highest and lowest positions of the machine tool respectively. Adjust the pose of the second reflective surface 2 until the shadows formed by the energy beams emitted by the energy beam emitter at the highest and lowest positions of the machine tool Z-axis on the visible test paper completely overlap. Step 5: Set a fourth reflective surface 4 below the first reflective surface 1 at the intersection of the A-axis and the C-axis. Set a third reflective surface 3 at the same height and parallel to the first side of the fourth reflective surface 4. Rotate the A-axis and C-axis to 0° and adjust the pose of the third reflective surface 3 and the fourth reflective surface 4 until the energy beam emitted by the energy beam emitter at the highest and lowest positions of the machine tool Z-axis, respectively, is reflected by the third reflective surface 3 and the fourth reflective surface 4 and then emitted to overlap with the shadow formed by the visible test paper. Step 6: Install machining head 5 on the A-axis. Set an adjustable focusing lens 6 inside the output end of machining head 5. Arrange paper tape on the horizontal surface below machining head 5. Position the A-axis at 0°. Position the C-axis at the first and second corners, with a 180° interval between the first and second corners. When the C-axis is at the first corner, move the energy beam emitter along the X-axis or Y-axis of the machine tool to obtain a first corner mark on the paper tape. When the C-axis is at the second corner, move the energy beam emitter along the X-axis or Y-axis of the machine tool to obtain a second corner mark on the paper tape. Adjust the orientation of the focusing lens 6 relative to the horizontal surface until the first and second corner marks coincide. Step 7: Rotate the A-axis and C-axis to different angle combinations and emit energy beams under different angle combinations. Place paper tape at the emission end of the energy beam. Determine whether the energy beam is affected by the rotation of the A-axis and C-axis based on the fine holes formed by the energy beam on the paper tape. If it is determined that the energy beam is affected by the rotation of the A-axis and C-axis, repeat steps 1-6 above until it is determined that the energy beam is not affected by the rotation of the A-axis and C-axis. If it is determined that the energy beam is not affected by the rotation of the A-axis and C-axis, the energy beam path adjustment is completed.

[0019] Example 2: This embodiment discloses a method for adjusting the energy beam path through a five-axis oscillating head, which is an optimization based on Embodiment 1. Step 1 specifically includes: Step 1.1: Make the emission axis of the energy beam emitter parallel to the Z-axis of the machine tool, disassemble the A-axis and C-axis, and the energy beam emitter emits an energy beam along the Z-axis of the machine tool; Step 1.2: A detection tube is coaxially positioned within the allowable coaxiality error range of the energy beam's emission path. A cross-shaped obstruction is placed inside the detection tube between the incident and exit ends. A visible test strip is placed at the exit end of the detection tube. The detection tube has a hollow internal structure, with two round rods arranged in a cross shape inside. A slot for fixing the visible test strip is provided at the exit end of the detection tube. When the energy beam enters from the incident end of the detection tube and passes through the round rods, it leaves a shadowed and unshadowed area on the visible test strip. The portion blocked by the round rods will not allow the energy beam to pass through, while the portion not blocked by the round rods passes through and projects onto the visible test strip, thus forming an image on the visible test strip. Figure 4 The four-petaled shadow shown.

[0020] Step 1.3: Raise the energy beam emitter along the Z-axis of the machine tool to the lowest position of the Z-axis, so that the energy beam forms a four-petal shadow on the visible test paper after passing through the cross-shaped obstruction. Adjust the pose of the energy beam emitter until the four petal shadows are equal in size. Step 1.4: Keep the position of the detection tube unchanged, raise the energy beam emitter along the Z-axis of the machine tool to the highest position of the Z-axis of the machine tool and emit the energy beam so that the energy beam forms a four-petal shadow on the visible test paper after passing through the cross-shaped obstruction. Compare the difference between the four-petal shadow formed by the energy beam emitter at the lowest position of the Z-axis of the machine tool and the highest position of the lowest position of the Z-axis of the machine tool. Step 1.5: Repeat steps 1.1-1.4 above until the two four-lobed shadows formed on the visible test paper by the energy beam emitted by the energy beam at the lowest position of the machine tool's Z-axis completely overlap. This completes the initial position adjustment of the energy beam emitter. At this time, ensure that the energy beam emitted by the energy beam emitter is emitted along the Z-axis of the machine tool, that is, ensure that the energy beam is emitted perpendicular to the horizontal plane.

[0021] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0022] Example 3: This embodiment discloses a method for adjusting the energy beam path through a five-axis oscillating head, which is an optimization based on embodiment 1 or 2. Step 2 specifically includes: Step 2.1: Install the A-axis and C-axis onto the Z-axis of the machine tool, and adjust the A-axis and C-axis to 0° so that the A-axis is parallel to the X-axis of the machine tool and the C-axis is parallel to the Z-axis of the machine tool. Arrange the first reflecting surface 1 at the bottom of the Z-axis of the machine tool. Step 2.2: A detection tube is set on the emission path of the energy beam after reflection by the first reflecting surface 1. The axis of the detection tube is parallel to the X-axis of the machine tool. A cross-shaped obstruction is set inside the detection tube between the incident end and the emission end. A visible test paper is set at the emission end of the detection tube, and the surface of the visible test paper is perpendicular to the X-axis of the machine tool. The function of the first reflecting surface 1 is to reflect and deflect the energy beam emitted along the Z-axis of the machine tool to a direction parallel to the X-axis of the machine tool. The Z-axis of the machine tool is the vertical direction of the horizontal plane, and the X-axis of the machine tool is the direction parallel to the horizontal plane. The axis of the detection tube is set parallel to the X-axis of the machine tool, and the visible test paper is set perpendicular to the X-axis of the machine tool at the emission end of the detection tube. Step 2.3: The energy beam emitter emits an energy beam to form a four-petal shadow on the visible test paper. The pose of the first reflective surface 1 is adjusted until the four petal shadows are of equal size. Here, the main adjustment is the tilt angle of the first reflective surface 1 relative to the horizontal plane. Step 2.4: Emits an energy beam at the near end of the X-axis of the machine tool, ensuring that the energy beam hits the linear test paper. Keep the first reflective surface 1 in the same position and keep the axis of the detection cylinder parallel to the X-axis of the machine tool. Move the position of the detection cylinder until the four petals of shadow formed on the visible test paper after the energy beam passes through the detection cylinder are of equal size.
