Description

Technical Field

[0001] This invention relates to an improvement in panel mounting technology, belonging to the field of machining, and particularly to a panel mounting method. Background Technology

[0002] To ensure the normal linear reciprocating motion of large, movable components, a half-type bushing is typically used at the mounting support position. The bushing is arranged around the circumference of the movable component to provide support. To prevent direct friction between the bushing and the external support cylinder, a removable plate is usually placed on the outside of the bushing. This plate needs to be in full contact with the bushing and the external support cylinder to achieve its wear-resistant function. These plates are often made of wear-resistant, corrosion-resistant, low-modulus nylon or other composite materials, but their rigidity is poor, and they are prone to deformation during clamping. Therefore, strict control is required during processing to ensure that the corresponding dimensional tolerances are met. In existing technologies, the plates are assembled by tooling or spot welding before precision machining to ensure the consistency of the inner diameter of the plate. However, using tooling to forcefully compress the workpiece's shape or inner diameter can lead to excessive internal stress after machining, making it difficult to meet the product's dimensional tolerance requirements.

[0003] Chinese patent application CN202021709462.8, filed on August 16, 2020, discloses a sheet metal processing device, including a processing table and a multi-axis slide table disposed above the processing table. The multi-axis slide table is equipped with a cutting tool facing the processing table. The processing table is equipped with a support member that lifts the sheet metal upwards. The multi-axis slide table is equipped with a scanning arm extending into the lower end face of the sheet metal. The end of the scanning arm is equipped with an intelligent sensor for inverted scanning and identification of the bottom surface of the sheet metal. This solution quickly and accurately measures the thickness and flatness of the sheet metal at any workstation, ensuring the stability and reliability of the cutting tool during processing, effectively reducing production costs, and meeting the needs of large-scale production of large-volume furniture orders. It effectively improves processing quality and efficiency, but it does not solve the problem of excessive internal stress after part processing.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this patent application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem of excessive internal stress after part processing in the prior art, and to provide a processing method for a bonding plate with less internal stress after part processing.

[0006] To achieve the above objectives, the technical solution of the present invention is: a method for processing a mounting plate, the method comprising the following steps:

[0007] The first step is to turn the blank, leaving a allowance on one side, to obtain the turned blank shape. Then, the turned blank shape is cut along the circumference to obtain multiple panel outlines.

[0008] The second step is to heat-treat the above-mentioned panel outline to remove residual stress inside the material in order to obtain a semi-finished panel.

[0009] The third step is to place the above-mentioned semi-finished plate on the base, perform reverse scanning on the semi-finished plate and the base to obtain the actual outline, and then use the actual outline as the blank for CNC machining to perform CNC machining to obtain the milled plate.

[0010] The fourth step is to place the milled panel on a drilling fixture, fix it in place, and then drill holes in the milled panel to obtain the finished panel.

[0011] In the fourth step, drilling holes is performed on the milled board to obtain the finished board. This also includes cleaning the drilled board with anhydrous alcohol. After cleaning, once the board surface is completely dry, a phased array ultrasonic instrument is used to perform all-round ultrasonic flaw detection.

[0012] During the testing process, each drilled area and surrounding area of ​​the board are scanned according to the preset testing parameters to ensure coverage of all critical areas;

[0013] If the flaw detection results show that the panel has the above-mentioned defects, it indicates that its structural integrity has been damaged and it cannot meet the strength requirements. The defect location must be marked immediately and milling and drilling must be carried out again. If no defects are found, the panel drilling process is deemed qualified and can proceed to the next step.

[0014] The first step involves turning the blank, leaving a allowance on one side, to obtain a turned blank. Then, the turned blank is cut along its circumference to obtain multiple panel contours, specifically:

[0015] First, turn the inner and outer circles to cut out the ring-shaped parts. Then, put it on a vertical lathe and use a four-jaw chuck to clamp the outer circle of the workpiece. Turn the inner and outer circles of the blank and chamfer both ends. Install the positioning groove in the middle of the inner circle. Then, use a parting tool to cut out a ring-shaped part. Then, remove the cut ring-shaped part. Then, follow the above steps to cut out three plate-mounted ring-shaped parts for the remaining clamped length of the blank.

[0016] First, machine the inner and outer circles, leaving a 5-10mm allowance on each side.

[0017] The blank is a hollow cylindrical blank.

[0018] In the second step, the outline of the above-mentioned panel is heat-treated to remove residual stress inside the material, in order to obtain a semi-finished panel, specifically:

[0019] Use anhydrous alcohol to thoroughly clean each ring component of the panel. Utilize the strong detergency and rapid evaporation of anhydrous alcohol to remove impurities from the surface of the ring component. After cleaning, place the ring components one by one into a hot water tank filled with deionized water, ensuring that the ring components are completely submerged and that there are gaps between them.

[0020] Then, the heating device is turned on to heat the deionized water in the hot water tank. The heating rate is strictly controlled to not exceed 5℃ / 15min. The water temperature is slowly raised to 100±5℃ and heated continuously for 10-15 hours.

[0021] After heating is complete, the ring-shaped part is removed and allowed to cool naturally to room temperature. At this point, the residual stress inside the ring-shaped part has been fully released, resulting in a semi-finished product.

[0022] The third step involves placing the semi-finished panel onto the base and performing a reverse scan of the semi-finished panel and the base to obtain the actual contour. Then, using the actual contour as the blank for CNC machining, CNC machining is performed to obtain the milled panel. Specifically:

[0023] First, place the plaque stably on the preset scanning fixture. The positioning structure of the fixture ensures that the plaque is in a vertical position to avoid distortion of scanning data due to tilting. Then, use a hot melt glue gun to evenly apply hot melt glue around the joint between the plaque and the scanning fixture. After the glue cools and solidifies, the plaque will be firmly bonded to the fixture, preventing displacement due to slight vibration during scanning.

[0024] Then, the handheld laser scanner is used to perform a 3D overall scan of the mounting plate and the scanning fixture. During the scan, the mounting plate is scanned from multiple angles and directions to obtain the actual mounting plate blank and its placement position on the scanning fixture.

[0025] The milled part is placed on a drilling fixture, which uses a central positioning groove and two side positioning blocks to position and clamp the plate.

[0026] The diameter of the hole to be processed is Φ18. First, pre-drill with a drill bit that is half the diameter of the hole to be processed, and then use a Φ12 end mill to perform layer milling to avoid cracking of the material.

[0027] The process of obtaining the finished plate further includes: wrapping the plate with non-woven fabric, and then vacuum drying the plate to prevent the edges from damaging the vacuum bag.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. In the processing method of the cladding plate of the present invention, the blank is first turned, leaving a allowance on one side to obtain a turned blank. Then, the turned blank is cut along the circumference to obtain multiple cladding plate contours. The cladding plate contours are heat-treated to remove residual stress inside the material to obtain a cladding plate semi-finished product. The cladding plate semi-finished product is placed on a base, and the cladding plate semi-finished product and the base are reverse-scanned to obtain the actual contour. Then, the actual contour is used as the blank for CNC machining to obtain the milled cladding plate. The milled cladding plate is placed on a drilling fixture and fixed. Then, holes are drilled in the milled cladding plate to obtain the finished cladding plate. The advantages of this design are as follows:

[0030] Firstly, by turning the blank as a whole and leaving a single-sided allowance, the material waste of independent rough machining of a single part is reduced, and the material loss is reduced; multiple panel contours are obtained by cutting along the circumference, which realizes the concentrated use of materials and is more efficient than the traditional single-piece blanking method. At the same time, the allowance provides adjustment space for subsequent finishing, avoiding the impact of initial size error on the final accuracy.

[0031] Secondly, the internal residual stress of the plate material is removed by heat treatment. At the same time, after the plate is fully deformed by heat treatment, reverse scanning is used to obtain the true blank shape. The true blank shape is then used as the blank for the machining program, which reduces the number of idle passes and makes it easier to control the depth of cut and feed rate of the tool, preventing large internal residual stress in the parts caused by large depth of cut and large feed.

[0032] Thirdly, the actual outline of the semi-finished board is obtained through reverse scanning, and CNC machining is performed based on this. This avoids errors caused by initial deformation of the blank or dimensional changes after heat treatment. At the same time, it ensures that the key dimensions of the board meet the tolerance requirements.

[0033] Therefore, the internal stress of the parts of this invention is relatively small after processing.

[0034] 2. In the processing method of the mounting plate of the present invention, the mounting plate blank is a hollow cylindrical blank, which reduces the manufacturing difficulty of the blank compared with the arc-shaped blank; it can improve the material utilization rate compared with the block blank; the cylindrical blank can be cut along the circumference and length direction, which facilitates continuous operation and improves production efficiency. Therefore, the present invention has low manufacturing difficulty and is easy to operate.

[0035] 3. In the processing method of the mounting plate of the present invention, the mounting plate is placed stably on a preset scanning fixture. The positioning structure of the fixture ensures that the mounting plate is in a vertical position, avoiding data distortion caused by tilting. Then, hot melt glue is evenly applied around the joint between the mounting plate and the scanning fixture using a hot melt glue gun. After the glue cools and solidifies, the mounting plate is firmly bonded to the fixture, preventing displacement due to slight vibrations during scanning. Therefore, the present invention is safe to use and stable in operation. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] See Figures 1 to 5 A method for processing a mounting plate, the method comprising the following steps:

[0043] The first step is to turn the blank, leaving a allowance on one side, to obtain the turned blank shape. Then, the turned blank shape is cut along the circumference to obtain multiple panel outlines.

[0044] The second step is to heat-treat the above-mentioned panel outline to remove residual stress inside the material in order to obtain a semi-finished panel.

[0045] The third step is to place the above-mentioned semi-finished plate on the base, perform reverse scanning on the semi-finished plate and the base to obtain the actual outline, and then use the actual outline as the blank for CNC machining to perform CNC machining to obtain the milled plate.

[0046] The fourth step is to place the milled panel on a drilling fixture, fix it in place, and then drill holes in the milled panel to obtain the finished panel.

[0047] In the fourth step, drilling holes is performed on the milled board to obtain the finished board. This also includes cleaning the drilled board with anhydrous alcohol. After cleaning, once the board surface is completely dry, a phased array ultrasonic instrument is used to perform all-round ultrasonic flaw detection.

[0048] During the testing process, each drilled area and surrounding area of ​​the board are scanned according to the preset testing parameters to ensure coverage of all critical areas;

[0049] If the flaw detection results show that the panel has the above-mentioned defects, it indicates that its structural integrity has been damaged and it cannot meet the strength requirements. The defect location must be marked immediately and milling and drilling must be carried out again. If no defects are found, the panel drilling process is deemed qualified and can proceed to the next step.

[0050] The first step involves turning the blank, leaving a allowance on one side, to obtain a turned blank. Then, the turned blank is cut along its circumference to obtain multiple panel contours, specifically:

[0051] First, turn the inner and outer circles to cut out the ring-shaped parts. Then, put it on a vertical lathe and use a four-jaw chuck to clamp the outer circle of the workpiece. Turn the inner and outer circles of the blank and chamfer both ends. Install the positioning groove in the middle of the inner circle. Then, use a parting tool to cut out a ring-shaped part. Then, remove the cut ring-shaped part. Then, follow the above steps to cut out three plate-mounted ring-shaped parts for the remaining clamped length of the blank.

[0052] First, machine the inner and outer circles, leaving a 5-10mm allowance on each side.

[0053] The blank is a hollow cylindrical blank.

[0054] In the second step, the outline of the above-mentioned panel is heat-treated to remove residual stress inside the material, in order to obtain a semi-finished panel, specifically:

[0055] Use anhydrous alcohol to thoroughly clean each ring component of the panel. Utilize the strong detergency and rapid evaporation of anhydrous alcohol to remove impurities from the surface of the ring component. After cleaning, place the ring components one by one into a hot water tank filled with deionized water, ensuring that the ring components are completely submerged and that there are gaps between them.

[0056] Then, the heating device is turned on to heat the deionized water in the hot water tank. The heating rate is strictly controlled to not exceed 5℃ / 15min. The water temperature is slowly raised to 100±5℃ and heated continuously for 10-15 hours.

[0057] After heating is complete, the ring-shaped part is removed and allowed to cool naturally to room temperature. At this point, the residual stress inside the ring-shaped part has been fully released, resulting in a semi-finished product.

[0058] The third step involves placing the semi-finished panel onto the base and performing a reverse scan of the semi-finished panel and the base to obtain the actual contour. Then, using the actual contour as the blank for CNC machining, CNC machining is performed to obtain the milled panel. Specifically:

[0059] First, place the plaque stably on the preset scanning fixture. The positioning structure of the fixture ensures that the plaque is in a vertical position to avoid distortion of scanning data due to tilting. Then, use a hot melt glue gun to evenly apply hot melt glue around the joint between the plaque and the scanning fixture. After the glue cools and solidifies, the plaque will be firmly bonded to the fixture, preventing displacement due to slight vibration during scanning.

[0060] Then, the handheld laser scanner is used to perform a 3D overall scan of the mounting plate and the scanning fixture. During the scan, the mounting plate is scanned from multiple angles and directions to obtain the actual mounting plate blank and its placement position on the scanning fixture.

[0061] The milled part is placed on a drilling fixture, which uses a central positioning groove and two side positioning blocks to position and clamp the plate.

[0062] The diameter of the hole to be processed is Φ18. First, pre-drill with a drill bit that is half the diameter of the hole to be processed, and then use a Φ12 end mill to perform layer milling to avoid cracking of the material.

[0063] The process of obtaining the finished plate further includes: wrapping the plate with non-woven fabric, and then vacuum drying the plate to prevent the edges from damaging the vacuum bag.

[0064] The supplementary technical features of this invention are as follows:

[0065] The system automatically stitches and processes the scanned data to generate a 3D model that includes the complete shape of the actual blank (such as dimensions, surface accuracy, surface roughness, and other details) and the specific placement position of the blank on the scanning fixture (such as spatial parameters such as offset and angle relative to the fixture positioning reference). This not only accurately restores the actual state of the blank, but also provides an intuitive and precise digital basis for subsequent processing calibration and dimensional inspection, effectively improving processing accuracy and efficiency.

[0066] Example 1:

[0067] A method for processing a mounting plate, the method comprising the following steps:

[0068] The first step is to turn the blank, leaving a allowance on one side, to obtain the turned blank shape. Then, the turned blank shape is cut along the circumference to obtain multiple panel outlines.

[0069] The second step is to heat-treat the above-mentioned panel outline to remove residual stress inside the material in order to obtain a semi-finished panel.

[0070] The third step is to place the above-mentioned semi-finished plate on the base, perform reverse scanning on the semi-finished plate and the base to obtain the actual outline, and then use the actual outline as the blank for CNC machining to perform CNC machining to obtain the milled plate.

[0071] The fourth step is to place the milled panel on a drilling fixture, fix it in place, and then drill holes in the milled panel to obtain the finished panel.

[0072] Example 2:

[0073] Example 2 is basically the same as Example 1, except that:

[0074] In the fourth step, drilling holes is performed on the milled board to obtain the finished board. This also includes cleaning the drilled board with anhydrous alcohol. After cleaning, once the board surface is completely dry, a phased array ultrasonic instrument is used to perform all-round ultrasonic flaw detection.

[0075] During the testing process, each drilled area and surrounding area of ​​the board are scanned according to the preset testing parameters to ensure coverage of all critical areas;

[0076] If the flaw detection results show that the panel has the above-mentioned defects, it indicates that its structural integrity has been damaged and it cannot meet the strength requirements. The defect location must be marked immediately and milling and drilling must be carried out again. If no defects are found, the panel drilling process is deemed qualified and can proceed to the next step.

[0077] Example 3:

[0078] Example 3 is basically the same as Example 1, except that:

[0079] The first step involves turning the blank, leaving a allowance on one side, to obtain a turned blank. Then, the turned blank is cut along its circumference to obtain multiple panel contours, specifically:

[0080] First, turn the inner and outer circles to cut out the ring-shaped parts. Then, place the workpiece on a vertical lathe and use a four-jaw chuck to clamp the outer circle of the workpiece. Turn the inner and outer circles of the blank and chamfer both ends. Install the positioning groove in the middle of the inner circle. Then, use a parting tool to cut out a ring-shaped part and remove the cut ring-shaped part. Then, follow the above steps to cut out three plate-mounted ring-shaped parts for the remaining clamping length of the blank. When turning the inner and outer circles first, leave a 5-10mm allowance on each side. The blank is a hollow cylindrical blank.

[0081] Example 4:

[0082] Example 4 is basically the same as Example 1, except that:

[0083] First, each plate ring is thoroughly cleaned with anhydrous alcohol. The strong cleaning power and rapid evaporation of anhydrous alcohol remove metal shavings, oil, coolant and other impurities that remain on the surface of the ring during the cutting process. This prevents impurities from adhering to the surface or penetrating into the material during subsequent heat treatment, which would affect the treatment effect. After cleaning, the plate rings are placed one by one into a hot water tank filled with deionized water, ensuring that the rings are completely submerged and that there are gaps between them to avoid uneven heating caused by stacking.

[0084] Subsequently, the heating device is activated to heat the deionized water in the hot water tank, strictly controlling the heating rate to not exceed 5℃ / 15min, and slowly raising the water temperature to 100±5℃. This slow heating process avoids the generation of new thermal stress inside the ring-shaped part due to sudden temperature changes, ensuring uniform temperature change across all parts of the material. Heating continues for 10-15 hours. Through this prolonged constant-temperature treatment, the residual stress generated during cutting and processing inside the ring-shaped part gradually relaxes and releases under the influence of heat, reducing the risk of deformation and cracking due to stress concentration during subsequent processing or use. After heating, the ring-shaped part is removed and allowed to cool naturally to room temperature. At this point, the residual stress inside the ring-shaped part has been fully released, resulting in more stable material properties and a semi-finished product with superior mechanical properties, laying a reliable foundation for subsequent finishing processes. The entire heat treatment process, through precise temperature control, sufficient processing time, and rigorous pre-treatment cleaning, effectively ensures the quality stability of the ring-shaped part, resulting in a semi-finished product.

[0085] First, place the plaque stably on the preset scanning fixture. The positioning structure of the fixture ensures that the plaque is in a vertical position to avoid distortion of scanning data due to tilting. Then, use a hot melt glue gun to evenly apply hot melt glue around the joint between the plaque and the scanning fixture. After the glue cools and solidifies, the plaque will be firmly bonded to the fixture, preventing displacement due to slight vibration during scanning.

[0086] Then, the handheld laser scanner is used to perform a 3D overall scan of the mounting plate and the scanning fixture. During the scan, the mounting plate is scanned from multiple angles and directions to obtain the actual mounting plate blank and its placement position on the scanning fixture.

[0087] The milled part is placed on a drilling fixture, which uses a central positioning groove and two side positioning blocks to position and clamp the plate.

[0088] The diameter of the hole to be processed is Φ18. First, pre-drill with a drill bit that is half the diameter of the hole to be processed, and then use a Φ12 end mill to perform layer milling to avoid cracking of the material.

[0089] The process of obtaining the finished plate further includes: wrapping the plate with non-woven fabric, and then vacuum drying the plate to prevent the edges from damaging the vacuum bag.

[0090] Example 5:

[0091] Example 5 is basically the same as Example 1, except that:

[0092] Step 1: First, turn the inner and outer circles to cut out the ring-shaped part; place it on a vertical lathe, use a four-jaw chuck to clamp the outer circle of the workpiece, and turn the inner and outer circles of the workpiece (approximately 10mm higher than the workpiece's net height, in this example Φ750 / Φ660*170mm), as well as chamfering the two ends at 20*8, and install a positioning groove of Φ680*50 in the middle of the inner circle; then use a parting tool to cut out a ring-shaped part with a height of 170mm (leaving an allowance of approximately 5mm in height), and remove the cut ring-shaped part; repeat this process for the remaining clamped length of blank, cutting out 3 ring-shaped parts (they must be consistent, i.e., the inner and outer circles, chamfering at both ends, and inner ring groove are machined to the required position, leaving a 0.5mm allowance at the cut end face);

[0093] Step 2: Machine the end face of the cut-off end of the ring part to ensure the height of the workpiece; continue on the vertical machine, turn the workpiece over, and position it with the end face machined from the ring part. With the end face of the cut-off end of the grooving tool facing upward, use the pressure plate to press the step at the inner groove, and machine the end face of the workpiece to ensure that the parallelism of the two end faces is within 0.10mm.

[0094] The third step is to mill the workpiece. Place the ring-shaped part obtained in the second step on the cutting fixture, use the Φ660 inner hole for positioning, use a pressure plate to press the workpiece, the pressing torque is not greater than 12Nm, use a milling head with an end mill, and use milling to divide the ring and process 3 workpieces.

[0095] Step 4: Heat treat the three divided panel parts. Clean the panel parts with anhydrous alcohol, then place them in a hot water tank filled with deionized water. The heat treatment equipment is an electrically heated hot water tank. Place the end face of the panel part in contact with the bottom of the hot water tank, keeping it free in the diameter direction, and gently press it down with a pressure plate to prevent it from tipping over. Heat the water to 100±5℃, and the heating rate should not exceed 5℃ / 15min. After boiling in the water for 10~15 hours, remove the panel parts to fully release the residual stress inside the panel blank.

[0096] Step 5: Place the three mounting plates on the scanning fixture, keeping them vertical. Use a hot melt glue gun to fix the mounting plates around the joint between the mounting plates and the scanning fixture. Use a handheld laser scanner to perform a 3D scan of the mounting plates and the scanning fixture (including four columns) to obtain the actual mounting plate blank and its placement position on the scanning fixture. Since the mounting plates are irregularly shaped, it is impossible to find the theoretical CNC machining coordinate system after deformation. The scanning fixture is integrated with the mounting plates and uses four columns to facilitate finding the CNC machining coordinate system.

[0097] Step 6: In the CNC programming software, align the scanning fixture with the theoretical fixture, and then use the optimal placement position to align the actual blank with the theoretical model to ensure that the machining allowance is minimized; connect the columns at symmetrical positions of the cross to serve as the X and Y directions respectively, and output the CNC machining program.

[0098] Step 7: Place the scanning fixture on the CNC milling machine, use a dial indicator to measure the center of each column, connect the centers of the symmetrical columns to obtain the X and Y directions of the machining coordinate system, and then follow the tool path of the CNC program. During milling, the tool must be sharp, with a rake angle of 10-15°. Use a high linear velocity and small feed rate to avoid overheating and part cracking. In this case, a Φ20 end mill is used with a rake angle of 12°, a linear velocity of 300 mm / min, a feed rate of 0.2 mm / r, and a depth of cut of 0.5 mm. Keeping the clamping unchanged, machine the outer arc, inner arc, and positioning groove of the plate in sequence.

[0099] Step 8: Place the mounting plate on the side hole machining fixture using the positioning groove, with the two side baffles close to the sides of the mounting plate, and then drill holes in the mounting plate; the drilling process is as follows: the diameter of the hole to be processed is Φ18, first use a drill bit (Φ10) with a diameter of about half the diameter of the hole to be processed for pre-drilling, and then use a Φ12 end mill for layer milling to avoid material cracking.

[0100] Step 9: Clean the parts with anhydrous alcohol to ensure that the surface is free of impurities. Then, use a phased array ultrasonic instrument to perform ultrasonic testing on the material to check for defects such as delamination and cracking. If there are defects, the parts need to be reprocessed.

[0101] Step 10: Depending on the usage environment, different post-treatments are performed on the panels. In environments with high insulation requirements, vacuum drying of the panels is also required. Wrap the panels with non-woven fabric to prevent the sharp edges from damaging the vacuum bag. Place the wrapped panels into the vacuum bag and seal it with sealing strips. Insert a nozzle into the vacuum bag and use a vacuum pump to perform vacuuming, ensuring a vacuum level of -0.08 to -0.10 MPa. Place the panels in the vacuum bag in a drying oven and dry at 60–80°C for 4 hours.

The water temperature is slowly raised to 100±5℃ and heated continuously for 10-15 hours. After heating is complete, the ring-shaped part is removed and allowed to cool naturally to room temperature. At this point, the residual stress inside the ring-shaped part has been fully released, resulting in a semi-finished product.

7. The method for processing a mounting plate according to claim 1, characterized in that: The third step involves placing the semi-finished panel onto the base and performing a reverse scan of the semi-finished panel and the base to obtain the actual contour. Then, using the actual contour as the blank for CNC machining, CNC machining is performed to obtain the milled panel. Specifically: First, place the plaque stably on the preset scanning fixture. The positioning structure of the fixture ensures that the plaque is in a vertical position to avoid distortion of scanning data due to tilting. Then, use a hot melt glue gun to evenly apply hot melt glue around the joint between the plaque and the scanning fixture. After the glue cools and solidifies, the plaque will be firmly bonded to the fixture, preventing displacement due to slight vibration during scanning. Then, the handheld laser scanner is used to perform a 3D overall scan of the mounting plate and the scanning fixture. During the scan, the mounting plate is scanned from multiple angles and directions to obtain the actual mounting plate blank and its placement position on the scanning fixture.

8. The method for processing a mounting plate according to claim 7, characterized in that: The milled part is placed on a drilling fixture, which uses a central positioning groove and two side positioning blocks to position and clamp the plate.

9. A method for processing a mounting plate according to claim 8, characterized in that: The diameter of the hole to be processed is Φ18. First, pre-drill with a drill bit that is half the diameter of the hole to be processed, and then use a Φ12 end mill to perform layer milling to avoid cracking of the material.

10. A method for processing a mounting plate according to any one of claims 1 to 9, characterized in that: The process of obtaining the finished plate further includes: wrapping the plate with non-woven fabric, and then vacuum drying the plate to prevent the edges from damaging the vacuum bag.
