[0002] Irregularly shaped workpieces possess advantages such as high temperature resistance, light weight, and high strength, making them suitable for high-temperature structural components such as complex irregularly shaped leading edges of aircraft. In the manufacturing process of these structural components, near-net-shape forming processes are generally used to prepare the shape of the irregularly shaped workpiece, while high-precision features such as mating positions are machined using advanced machining processes.

[0003] However, due to the limitations of the forming process precision, the shape accuracy of its irregular surface generally has a small deviation, which affects the clamping and alignment accuracy and the final machining accuracy. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide an attitude adjustment component, processing equipment and method for irregularly shaped workpieces, so as to solve the problem of poor clamping accuracy of irregularly shaped workpieces in the prior art.

[0005] The objective of this invention is mainly achieved through the following technical solutions: This invention provides a posture adjustment assembly for an irregularly shaped workpiece, including an XY-axis adjustment component. The XY-axis adjustment component includes an XY-axis adjustment support, an X-axis adjustment pin, a Y-axis adjustment pin, and a Y-axis adjustment block. The X-axis adjustment pin passes through the XY-axis adjustment support along the length of the irregularly shaped workpiece and its relative position to the XY-axis adjustment support is adjustable. The X-axis adjustment pin abuts against the irregularly shaped workpiece. One end of the Y-axis adjustment block is fixedly connected to the XY-axis adjustment support, and the other end of the Y-axis adjustment block is a suspended end. The Y-axis adjustment pin passes through the suspended end of the Y-axis adjustment block and its relative position to the Y-axis adjustment block is adjustable. The Y-axis adjustment pin abuts against the upper surface of the irregularly shaped workpiece.

[0006] Furthermore, there are two sets of XY-axis adjusting components, which are respectively located at both ends of the irregular workpiece and are arranged opposite to each other; the irregular workpiece is located between the X-axis adjusting pins of the two sets of XY-axis adjusting components.

[0007] Furthermore, the XY-direction adjusting component also includes a pressure block locking screw, which is fixedly connected to the XY-direction adjusting support.

[0008] Furthermore, a long through hole extending along the length of the irregular workpiece is opened on the Y-axis adjusting pressure block, and the pressure block locking screw passes through the long through hole and is fixedly connected to the XY-axis adjusting support.

[0009] Furthermore, it also includes a Z-axis adjustment component, which is used for reference adjustment of irregularly shaped workpieces in the Z-axis direction.

[0010] Furthermore, the Z-axis adjusting component includes a Z-axis adjusting support and multiple Z-axis adjusting pins; the cross-sectional shape of the Z-axis adjusting support is fork-shaped, including a connecting seat and two fork walls located at the top of the connecting seat, with a gap between the two fork walls, a portion of the Z-axis adjusting pins penetrates one of the fork walls along the thickness direction of the irregular workpiece and then abuts against the irregular workpiece, and another portion of the Z-axis adjusting pins penetrates the other fork wall along the thickness direction of the irregular workpiece and then abuts against the irregular workpiece.

[0011] Furthermore, the number of Z-axis adjustment components is multiple.

[0012] Furthermore, multiple Z-axis adjusting pins are arranged in multiple pairs, with each pair of Z-axis adjusting pins corresponding to each other. One Z-axis adjusting pin penetrates one of the fork walls, and the other Z-axis adjusting pin penetrates the other fork wall.

[0013] The present invention also provides a processing equipment for irregularly shaped workpieces, characterized in that it includes a clamping fixture, the clamping fixture including the aforementioned posture adjustment component for the irregularly shaped workpiece.

[0014] The present invention also provides a method for processing irregularly shaped workpieces, using the aforementioned processing equipment for irregularly shaped workpieces.

[0015] Compared with the prior art, the present invention can achieve at least the following beneficial effects: A) The posture adjustment component for irregularly shaped workpieces provided by the present invention can realize the posture alignment of irregularly shaped workpieces in the length and width directions by setting XY-axis adjustment components. The posture adjustment accuracy is high, thereby improving the subsequent processing accuracy of irregularly shaped workpieces.

[0016] B) The posture adjustment component for irregularly shaped workpieces provided by the present invention can change the length of the suspended part of the Y-axis adjusting pressure block by changing the relative position of the pressure block locking screw and the elongated through hole. When it is necessary to avoid the processing area, the pressure block locking screw can be loosened and the Y-axis adjusting pressure block can be moved to the outside of the irregularly shaped workpiece 4. The length of the suspended part of the Y-axis adjusting pressure block becomes smaller. At this time, tightening the pressure block locking screw completes the avoidance adjustment of the Y-axis adjusting pressure block.

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and are used together with the invention to illustrate the principles of the invention.

[0022] Example 1 This embodiment provides a posture adjustment component for irregularly shaped workpieces. See [link to component]. Figures 1 to 2 It includes an XY-direction adjustment component 2, which is used for the reference adjustment of the irregular workpiece 4 in the XY direction. Here, the X direction refers to the length direction of the irregular workpiece 4, and the Y direction refers to the width direction of the irregular workpiece 4.

[0023] Specifically, there are two sets of XY-direction adjusting components 2, respectively located at both ends of the irregularly shaped workpiece 4 and arranged opposite to each other. These include XY-direction adjusting supports 201 and X-direction adjusting pins 202, Y-direction adjusting pins 203, and Y-direction adjusting blocks 204. (See [reference]). Figure 1The X-axis adjusting pin 202 passes through the XY-axis adjusting support 201 along the length of the irregular workpiece 4, and its relative position to the XY-axis adjusting support 201 is adjustable (for example, the length of the pin passing through the XY-axis adjusting support 201 can be adjusted by rotating the X-axis adjusting pin 202). The irregular workpiece 4 is located between the X-axis adjusting pins 202 of the two sets of XY-axis adjusting members 2, and the X-axis adjusting pins 202 abut against the irregular workpiece 4. By adjusting the length of the X-axis adjusting pins 202 at both ends of the irregular workpiece 4 inserted into the XY-axis adjusting support 201, the relative position of the irregular workpiece 4 in the X direction can be adjusted; Y One end of the Y-axis adjusting block 204 is fixedly connected to the XY-axis adjusting support 201, and the other end of the Y-axis adjusting block 204 is a suspended end. The Y-axis adjusting pin 203 passes through the suspended end of the Y-axis adjusting block 204 and its relative position to the Y-axis adjusting block 204 is adjustable (for example, by rotating the Y-axis adjusting pin 203, the length of the pin passing through the Y-axis adjusting block 204 can be adjusted). The Y-axis adjusting pin 203 abuts against the upper surface of the irregular workpiece 4. By adjusting the length of the Y-axis adjusting pin 203 passing through the Y-axis adjusting block 204, the relative position of the irregular workpiece 4 in the Y direction can be adjusted.

[0024] Compared with the prior art, the posture adjustment component for irregular workpieces provided in this embodiment can achieve posture alignment of irregular workpiece 4 in the length and width directions by setting the XY axis adjustment component 2. The posture adjustment accuracy is high, thereby improving the subsequent processing accuracy of irregular workpiece 4.

[0025] Considering that the Y-axis adjusting block 204 may interfere with the processing area of ​​the irregular workpiece 4, in order to avoid the processing area, the aforementioned XY-axis adjusting component 2 also includes a block locking screw 205. The Y-axis adjusting block 204 has an elongated through hole extending along the length of the irregular workpiece 4. The block locking screw 205 passes through the elongated through hole and is fixedly connected to the XY-axis adjusting support 201. Thus, by changing the relative position of the block locking screw 205 and the elongated through hole, the length of the suspended portion of the Y-axis adjusting block 204 can be changed. When it is necessary to avoid the processing area, the block locking screw 205 can be loosened, and the Y-axis adjusting block 204 can be moved outwards from the irregular workpiece 4, reducing the length of the suspended portion of the Y-axis adjusting block 204. Then, tightening the block locking screw 205 completes the avoidance adjustment of the Y-axis adjusting block 204.

[0026] In order to adjust the Z-axis posture of the irregular workpiece, the posture adjustment component also includes a Z-axis adjustment component 3. The Z-axis adjustment component 3 is used for the reference adjustment of the Z-axis of the irregular workpiece 4. The Z-axis refers to the thickness direction of the irregular workpiece 4.

[0027] Similarly, there are multiple sets of Z-axis adjusting components 3, each including a Z-axis adjusting support 301 and multiple Z-axis adjusting pins 302, see [link / reference]. Figure 2The Z-axis adjusting support 301 has a fork-shaped cross-section, comprising a connecting seat and two fork walls located at the top of the connecting seat. A gap exists between the two fork walls. A portion of the Z-axis adjusting pins 302 penetrates one fork wall along the thickness direction of the irregular workpiece 4 and abuts against the irregular workpiece 4. Another portion of the Z-axis adjusting pins 302 penetrates the other fork wall along the thickness direction of the irregular workpiece 4 and abuts against the irregular workpiece 4. When it is necessary to adjust the Z-axis posture of the irregular workpiece 4, the lengths through which the multiple Z-axis adjusting pins 302 penetrate the fork walls are adjusted, thereby enabling the adjustment of the Z-axis posture of the irregular workpiece 4.

[0028] For ease of operation, the above-mentioned Z-axis adjusting pins 302 are arranged in multiple pairs, with each pair of Z-axis adjusting pins 302 corresponding to each other. One Z-axis adjusting pin 302 penetrates one of the fork walls, and the other Z-axis adjusting pin 302 penetrates the other fork wall.

[0029] In summary, the reference adjustment component of this embodiment, through the setting of the XY-axis adjustment component 2 and the Z-axis adjustment component 3, can adjust the posture of the irregular workpiece 4 in the X, Y and Z directions respectively, thereby achieving precise positioning of the irregular workpiece 4 in the subsequent processing.

[0030] Example 2 This embodiment provides a processing equipment for irregularly shaped workpieces, see [link to relevant documentation]. Figures 3 to 4 It includes a clamping fixture, which includes the posture adjustment component for the irregularly shaped workpiece provided in Embodiment 1.

[0031] Compared with the prior art, the beneficial effects of the processing equipment for irregularly shaped workpieces provided in this embodiment are basically the same as the beneficial effects of the posture adjustment component for irregularly shaped workpieces provided in Embodiment 1, and will not be described in detail here.

[0032] In order to clamp the irregular workpiece 4 without damage, the clamping fixture also includes a base plate 8 and a flexible clamping assembly 1. The reference adjustment assembly and the flexible clamping assembly 1 are both located on the base plate 8. The flexible clamping assembly 1 is used for flexible clamping and support of the irregular workpiece 4. The XY axis adjustment support 201 is located on the base plate 8.

[0033] Specifically, regarding the structure of the flexible clamping component 1, see [link to relevant documentation]. Figure 5The device includes a support base 101, a hydraulic clamping plate 102, and an array of floating clamping components 103. The hydraulic clamping plate 102 is mounted on the support base 101. There are multiple hydraulic clamping plates 102 and array of floating clamping components 103. Some of the hydraulic clamping plates 102 and array of floating clamping components 103 are located on one side of the irregular workpiece 4, and other hydraulic clamping plates 102 and array of floating clamping components 103 are located on the other side of the irregular workpiece 4. The array of floating clamping components 103 is located between the hydraulic clamping plate 102 and the irregular workpiece 4. The base of the array of floating clamping components 103 is fixedly connected to the hydraulic clamping plate 102, and the array of floating heads of the array of floating clamping components 103 contacts the irregular workpiece 4. It should be noted that existing floating support systems are typically located below the supported structure for support. In this embodiment, the processing equipment for irregularly shaped workpieces adds a hydraulic clamping plate 102 to provide sufficient clamping force to the array-type floating clamping member 103. Controllable clamping is achieved through hydraulic pressure, allowing the array-type floating clamping member 103 to be positioned on the side of the irregularly shaped workpiece 4. This transforms a typical structure that can only provide floating support into a floating clamping structure suitable for clamping irregularly shaped workpieces 4. Furthermore, by using the array-type floating clamping member 103 to clamp the irregularly shaped workpiece 4, there is no force contact between the array-type floating head and the irregularly shaped workpiece 4, achieving conformal clamping. This makes it suitable for complex surface errors of the irregularly shaped workpiece 4 and reduces damage caused by sharp clamping points.

[0034] In order to achieve controllable clamping, the above-mentioned flexible clamping component 1 also includes a liquid supply unit and a hydraulic valve 104. The liquid supply unit is connected to the hydraulic clamp 102, and the hydraulic valve 104 is located on the connecting pipeline between the liquid supply unit and the hydraulic clamp 102. The hydraulic valve 104 controls the loosening and tightening of the hydraulic clamp 102.

[0035] Considering that the surface to be machined on the irregular workpiece 4 needs to always face upwards during the machining process, after machining one surface of the irregular workpiece 4, it is necessary to adjust the position of the irregular workpiece 4 so that the other surface of the irregular workpiece 4 faces upwards. Therefore, the above-mentioned clamping fixture also includes a position quick-change assembly. For example, the position quick-change assembly includes a first position pull stud 5, a second position pull stud 6, and a third position pull stud 7. The first position pull stud 5 is located on the first side of the base plate 8, the second position pull stud 6 is located on the second side of the base plate 8, the first side and the second side are opposite to each other, and the third position pull stud 7 is located on the lower end face of the base plate 8.

[0036] Accordingly, the aforementioned clamping fixture has a first pose mode, a second pose mode, and a third pose mode. When the clamping fixture is in the first pose mode, the first pose pull pin 5 is positioned downwards and penetrates the machine tool of the machining equipment before being inserted into the zero-point positioning system of the machining equipment, achieving rapid positioning of the first pose. When the clamping fixture is in the second pose mode, the second pose pull pin 6 is positioned downwards and penetrates the machine tool of the machining equipment before being inserted into the zero-point positioning system of the machining equipment, achieving rapid positioning of the second pose. When the clamping fixture is in the third pose mode, the third pose pull pin 7 is positioned downwards and penetrates the machine tool of the machining equipment before being inserted into the zero-point positioning system of the machining equipment, achieving rapid positioning of the third pose. Thus, through the pose quick-change assembly with the above structure, high-precision reference transfer can be achieved to complete the machining of multiple surfaces in a single clamping operation.

[0037] Example 3 This embodiment provides a method for processing irregularly shaped workpieces, using the processing equipment provided in Embodiment 1 or Embodiment 2. The processing method includes the following steps: Step 1: Grind the surface of the irregular workpiece until the continuous silicon carbide coating is completely removed or the continuous silicon carbide coating at the corresponding position of the machining tool during the arc machining process is removed, exposing part of the carbon fiber. Step 2: Place the irregularly shaped workpiece in the clamping fixture, so that the clamping fixture clamps the irregularly shaped workpiece; Step 3: Rough machining of the irregularly shaped workpiece using electric arc machining; Step 4: Use ultrasonic vibration-assisted machining to finish the rough-machined irregular workpiece to the final part size.

[0038] Compared with existing technologies, the machining method for irregularly shaped workpieces provided in this embodiment adopts a combination of arc machining and ultrasonic vibration-assisted machining. First, arc machining is used for rough machining, which removes material efficiently and with high energy. However, the surface roughness of the irregularly shaped workpiece produced by arc machining is poor, and the recast layer affects the strength of the workpiece. Subsequently, ultrasonic vibration-assisted machining is used for finishing to remove defects such as the recast layer and cracks generated by arc machining. Ultrasonic vibration-assisted machining can generate cutting forces that are 1 / 3 to 1 / 2 smaller than conventional milling, which is beneficial for controlling the surface quality of irregularly shaped workpieces, ensuring the machining accuracy of the plane, and ensuring the dimensional accuracy of the irregularly shaped workpiece, while meeting the requirements of efficient and low-damage machining of irregularly shaped workpieces. On the other hand, the irregularly shaped workpiece is pre-treated before clamping, and the continuous silicon carbide coating is removed until the continuous silicon carbide coating at the corresponding position of the machining tool during arc machining is removed, exposing part of the carbon fiber. This can effectively improve the overall conductivity of the irregularly shaped workpiece during arc machining.

[0039] In order to process the material with more optimized process parameters, the following steps are included before step 1 above: Multiple test blanks are provided, and multiple test blanks are processed using different multi-energy field process parameters to obtain multiple test irregular-shaped workpieces; Calculate the comprehensive damage evaluation factor for each tested irregularly shaped workpiece; The optimal process parameter is the multi-energy field process parameter corresponding to the minimum value among multiple comprehensive damage evaluation factors; The optimal process parameters are adopted as the machining process parameters for irregularly shaped workpieces.

[0040] Specifically, the calculation of the comprehensive damage assessment factor includes the following steps: Step 1: Divide the surface of the irregularly shaped workpiece into multiple test irregularly shaped workpiece areas; Step II: Obtain the damage parameters of the irregularly shaped workpiece after processing. The damage parameters include the damage location, damage type, damage size (i.e., length and width), and recast layer thickness. Step III: Using a scanning electron microscope at the same magnification (e.g., 1000x), statistically analyze the damage parameters of the machined irregular workpiece in each test area to obtain a defect data table; Step IV: Calculate the crack damage evaluation factor, fiber debonding damage evaluation factor, and fiber pull-out damage evaluation factor for each test irregular workpiece area. The calculation formula for the crack damage evaluation factor is as follows: F a = N a / S In the formula, F a As a crack damage evaluation factor, N a To test the number of crack damage areas in irregularly shaped workpieces, S To test the area of ​​the irregularly shaped workpiece; The calculation formula for the fiber debonding damage evaluation factor is as follows: F b = N b / S In the formula, F b As an evaluation factor for fiber debonding damage, N b To test the amount of fiber debonding damage in the area of ​​the irregularly shaped workpiece, S To test the area of ​​the irregularly shaped workpiece; The formula for calculating the fiber pull-out damage evaluation factor is as follows: F c = N c / S In the formula, F c As a factor for evaluating fiber pull-out damage, N c To test the number of fiber pull-out damages in the area of ​​irregularly shaped workpieces, S To test the area of ​​the irregularly shaped workpiece; Step V: Calculate the regional damage evaluation factor based on the crack damage evaluation factor, fiber debonding damage evaluation factor, fiber pull-out damage evaluation factor, and recast layer thickness. The calculation formula for the regional damage evaluation factor is as follows: P=l 1 F a +l 2 F b +l 3 F c +l 4 F h In the formula, P As a regional damage assessment factor, l 1 represents the crack damage weight. F a As a crack damage evaluation factor, l 2 represents the fiber debonding damage weight. F b As an evaluation factor for fiber debonding damage, l 3 represents the fiber pull-out damage weight. F c As a factor for evaluating fiber pull-out damage, l 4 represents the damage weight of the recast layer. F h It is one-tenth the thickness of the recast layer.

[0041] in, l 1 +l 2 +l 3 +l 4=1, l 1 represents 0.2~0.5. l 2 represents 0.1~0.2. l 3 represents 0.1~0.2. l 4 represents 0.3~0.5.

[0042] Step VI: Calculate the sum of the regional damage evaluation factors of multiple test irregular workpiece areas and divide it by the result of the test irregular workpiece area to obtain the comprehensive damage evaluation factor.

[0043] In order to obtain accurate damage location, damage type, and damage size, step II above, which involves obtaining the damage location, damage type, and damage size of the irregularly shaped workpiece after processing, includes the following steps: Using a scanning electron microscope at low magnification (e.g., 100-500 times), the overall surface morphology of the processed test irregular workpiece is observed to determine the location of damage on the surface of the irregular workpiece in each test area. Using a scanning electron microscope at medium magnification (e.g., 1000-2000x), the damage morphology characteristics at the damage location are observed to determine the damage type. Statistical analysis is then performed to obtain the number of cracks, fiber debonding, and fiber pull-out in each test irregular workpiece area. Damage scales within each tested irregular workpiece area were obtained using a scanning electron microscope at high magnification (e.g., 5000 to 20000 times).

[0044] Similarly, in order to obtain an accurate recast layer thickness, the recast layer thickness can be obtained in step I above using the following method.

[0045] One approach includes the following steps: Step a: Cut the machined, irregularly shaped workpiece along the Z-axis. Step b: Use a scanning electron microscope to perform energy dispersive spectroscopy analysis on the cross-section of the machined irregular-shaped workpiece to obtain the oxygen content of the cross-section of the machined irregular-shaped workpiece. Step c: Draw the energy spectrum of thickness and oxygen content, and determine the thickness of the recast layer based on the location of oxygen fluctuations.

[0046] Another approach includes the following steps: Step a': Cut the machined, irregularly shaped workpiece along the Z-axis. Step b': Use an X-ray diffractometer to perform phase analysis on the cross-section of the machined irregular workpiece to obtain the phase diagram of the oxide; Step c': Determine the thickness of the recast layer based on the changes in oxide content in the phase diagram.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
