Description

Technical Field

[0001] This invention relates to the field of rolling and expanding technology, and more specifically, to a semiconductor aluminum alloy rolling ring size measuring device and its usage method. Background Technology

[0002] The aluminum alloy ring parts used in semiconductors have extremely high requirements for dimensional accuracy and roundness consistency. Real-time and accurate measurement of the outer diameter during the ring rolling process is the core link to ensure the product qualification rate and control the processing accuracy.

[0003] Chinese patent CN219757173U discloses a diameter measuring device for a ring rolling machine. By setting a measuring seat on the ring rolling machine, it can conveniently and quickly measure the outer diameter of the ring, reducing manual operation and improving safety. However, when measuring the ring, it is necessary to remove the ring and place it on the measuring seat for measurement. If the size does not meet the requirements, it needs to be reworked. The ring on the measuring seat is put back into the ring rolling machine for rolling and expansion processing. After processing, it is removed and measured again, which is very inconvenient. In addition, the temperature of the ring drops during the back and forth transfer process. The ring needs to be reheated before re-rolling and expansion processing, resulting in extremely low processing efficiency. Summary of the Invention

[0027] To better understand this invention, the following is combined with... Figures 1-12 The present invention provides a detailed description of a semiconductor aluminum alloy ring rolling size measuring device and its usage method.

[0028] Example 1: like Figures 1-3 As shown, a semiconductor aluminum alloy ring rolling dimension measuring device includes: Ring rolling machine 1 is used for rolling and expanding rings 5; The diameter measuring mechanism includes an adjusting component 2 and a measuring carriage 4. The measuring carriage 4 is connected to the adjusting component 2 via a rotating rod 3. One end of the rotating rod 3 is rotatably connected to the adjusting component 2, and the other end of the rotating rod 3 is rotatably connected to the measuring carriage 4. The outer wheel 41 of the measuring carriage 4 rolls and fits against the outer ring of the ring 5. Electric push rod 6, one end of which is rotatably connected to adjustment component 2, and the other end of which is rotatably connected to the middle of rotating rod 3.

[0029] It should be noted that the rolling process can be either radial rolling only on the ring 5, or both radial and axial rolling on the ring 5. The main roll 11 of the ring rolling mill 1 abuts against the outer ring of the ring 5, and the core roll 12 of the ring rolling mill 1 abuts against the inner ring of the ring 5. During radial rolling, the main roll 11 drives the ring 5 to rotate, and at the same time, the main roll 11 or the core roll 12 feeds radially, reducing the distance between the main roll 11 and the core roll 12, thereby thinning the wall thickness and increasing the diameter of the ring 5. During axial rolling, a pair of tapered rolls (not shown in the figure) of the ring rolling mill 1 roll axially, thereby reducing the height of the ring 5 and increasing its diameter. In addition, the ring rolling mill 1 is also equipped with a pair of clamping rolls (not shown in the figure), which center and guide the ring 5 during the rolling process to ensure the roundness of the ring 5. The design of the main roll 11, core roll 12, tapered roll and clamping roll are all existing technologies and will not be described in detail here. The outer wheels 41 are located outside the housing of the measuring carriage 4 so that they can directly contact the ring 5. The measuring carriage 4 is rotatably mounted with four outer wheels 41. The axis of the outer wheels 41 is parallel to the axis of the ring 5. The outer wheels 41 can be detachably rolled and attached to the outer ring of the ring 5 by means of an electric push rod 6. When the output end of the electric push rod 6 extends, it pushes the end of the rotating rod 3 away from the adjusting component 2 to rotate towards the ring 5. The measuring carriage 4 moves synchronously with the rotating rod 3 until the outer rings of all four outer wheels 41 are in contact with the outer ring of the ring 5. When the output end of the electric push rod 6 shortens, it drives the end of the rotating rod 3 away from the adjusting component 2 to rotate away from the ring 5, thereby moving the measuring carriage 4 away from the ring 5 and separating the outer wheels 41 from the ring 5. The adjustment component 2 is located on the outside of the ring rolling mill 1. The adjustment component 2 is used to adjust the height of the measuring carriage 4 to ensure that, under different installation conditions, during the rolling process of the ring rolling mill 1, the measuring carriage 4 remains in contact with the outer ring of the bottom of the ring 5, so as to avoid the measuring carriage 4 affecting the axial rolling of the ring 5. The outer ring of the outer wheel 41 is provided with a frosted texture to reduce the probability of relative slippage between the outer wheel 41 and the ring 5, ensuring the accuracy of the measurement. Given that the diameter of the outer wheel 41 is d, during the rolling process of the ring 5, by measuring the number of rotations n of the outer wheel 41 when the ring 5 rotates once, the outer diameter D=nd of the ring 5 can be calculated, thereby realizing online diameter measurement of the ring 5 without stopping the machine for inspection, which greatly improves the rolling processing efficiency of the semiconductor aluminum alloy ring 5.

[0030] It should be emphasized that under the action of rolling load, the main roll 11 and the core roll 12 will undergo elastic deformation, and the main roll 11 and the core roll 12 will wear after long-term use, which will cause the gap size between the main roll 11 and the core roll 12 to be mismatched with the actual wall thickness and outer diameter of the ring 5. Therefore, it is necessary to measure the outer diameter of the ring 5 to ensure the accuracy of rolling. During the initial measurement process, the feed speed of the main roller 11 or the core roller 12 is relatively fast, and the diameter of the ring 5 continuously increases. The calculated outer diameter is not the real-time outer diameter of the ring 5, but the outer diameter at a certain moment during the rotation of the ring 5. This calculated value can be regarded as the median value of the outer diameter of the ring 5 within the corresponding calculation time period. When the outer diameter of the ring exceeds the preset value, the feed speed of the main roller 11 or the core roller 12 gradually slows down or slows down in steps. At this time, the calculated outer diameter approaches the real-time outer diameter of the ring 5, thereby ensuring the accuracy of the measurement and that the measurement error is within the preset range. During the rolling process with a slowed feed speed, when the calculated outer diameter is within the preset range, it indicates that the outer diameter of the ring 5 meets the requirements, and the rolling is stopped.

[0031] In this embodiment, the outer wheel 41 is made of silicon nitride ceramic. Firstly, the silicon nitride outer wheel 41 has good heat resistance and a low coefficient of thermal expansion, making it suitable for contact between the outer wheel 41 and the high-temperature aluminum alloy ring 5. Under these high-temperature conditions, the outer wheel 41 does not deform, exhibits minimal thermal expansion error, and achieves high measurement accuracy. Secondly, the silicon nitride outer wheel 41 possesses excellent chemical inertness and has extremely low affinity for aluminum alloy oxide scale. The oxide scale on the outer ring 5 is unlikely to adhere to the outer wheel 41, thus ensuring measurement accuracy. Thirdly... The rotating rod 3 is suspended at one end connected to the measuring carriage 4. Silicon nitride has a low density and the outer wheel 41 is lightweight, which helps to reduce the overall weight of the measuring carriage 4, thereby reducing the load on the rotating rod 3 and preventing the rotating rod 3 from bending under long-term use, which would cause the axis of the outer wheel 41 to deviate and affect the accuracy of the measurement. Fourth, the outer wheel 41 made of silicon nitride has excellent wear resistance. Under long-term use, the outer wheel 41 can still maintain an accurate diameter, which helps to ensure the accuracy of the measurement and reduces maintenance and replacement costs.

[0032] Example 2: As an optimization of Example 1, such as Figure 7 and Figure 8 As shown, an inner wheel 43, which is rolledly connected to an outer wheel 41, is rotatably mounted inside the cavity 42 of the measuring carriage 4. A rotary encoder 44 is installed inside the cavity 42. The fixed end of the rotary encoder 44 is fixedly connected to the measuring carriage 4, and the input end of the rotary encoder 44 is drivenly connected to the rotating shaft of the inner wheel 43.

[0033] It should be noted that the measuring carriage 4 is fixedly equipped with a wheel frame 45. One end of the wheel frame 45 extends into the cavity 42, and the other end of the wheel frame 45 extends out of the housing. The outer wheels 41 and inner wheels 43 are rotatably mounted on the wheel frame 45. There are four inner wheels 43 and four wheel frames 45. The four inner wheels 43 are respectively rolledly connected to the four outer wheels 41. At least one rotary encoder 44 is installed in the cavity 42. The fixed end of the rotary encoder 44 is fixedly mounted on the wheel frame 45, and the input end of the rotary encoder 44 is fixedly connected to the rotating shaft of the inner wheel 43. The inner wheel 43 and the outer wheel 41 are in a rolling connection, meaning that the outer ring of the inner wheel 43 is in contact with the outer ring of the outer wheel 41. When the outer wheel 41 rotates, the friction of the contact surfaces drives the inner wheel 43 to rotate synchronously. There is no relative slippage between the inner wheel 43 and the outer wheel 41. Specifically, the outer ring of the inner wheel 43 is also provided with a frosted texture, thereby increasing the friction between the inner wheel 43 and the outer wheel 41 and avoiding relative slippage between the inner wheel 43 and the outer wheel 41, which would affect the accuracy of the measurement. By using a rotary encoder 44 to collect the number of rotations of the inner wheel 43, the number of rotations of the outer wheel 41 can be calculated. Compared with manual counting, this greatly improves the accuracy and convenience of measurement. The input end of the rotary encoder 44 is preset to output N fixed pulse signals for each rotation. When the ring 5 being processed completes one rotation, the rotary encoder 44 collects and outputs P pulse signals in real time. Then, the actual number of rotations of the inner wheel 43 is P / N. Given that the ratio of the diameter of the inner wheel 43 to the diameter of the outer wheel 41 is k, the actual number of rotations of the outer wheel 41 is n=kP / N. Therefore, the outer diameter D of the ring 5 is D=kdP / N. By utilizing the high-precision characteristics of pulse counting, the accurate measurement of the number of rotations of the inner wheel 43 can be achieved, thereby ensuring the accuracy of the outer diameter measurement of the ring 5. By setting the inner wheel 43, the input end of the rotary encoder 44 is connected to the shaft of the inner wheel 43 through a transmission connection. Both the inner wheel 43 and the rotary encoder 44 are located inside the cavity 42. Due to the obstruction of the housing, the temperature inside the cavity 42 is low, which helps to protect the rotary encoder 44, improve the service life of the rotary encoder 44, and reduce maintenance costs. If the rotary encoder 44 is directly used to measure the number of rotations of the outer wheel 41, that is, the input end of the rotary encoder 44 is connected to the shaft of the outer wheel 41 through a transmission connection, then the rotary encoder 44 is also located outside the housing of the measuring carriage 4. During the measurement process, the rotary encoder 44 is surrounded by a high-temperature environment, which makes the rotary encoder 44 prone to aging and failure, and the measurement accuracy will also be reduced.

[0034] In this embodiment, four rotary encoders 44 are installed inside the cavity 42. The input ends of the four rotary encoders 44 are fixedly connected to the shafts of the four inner wheels 43 respectively. The actual number of rotations of the inner wheels 43 is taken as the average of the number of rotations measured by the four rotary encoders 44, which reduces the error caused by possible slippage between the outer wheel 41 and the ring 5, thereby further improving the accuracy and reliability of the measurement.

[0035] Example 3: As an optimization of Example 2, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 9As shown, the adjustment assembly 2 includes an electric slide table 21, a mounting frame 22, a guide rod 23, an adjustment plate 24, a cylinder 25, a connecting rod 26, a traveling trolley 27, and a compression spring 28. The mounting frame 22 is fixedly installed on the output end of the electric slide table 21. The guide rod 23 is fixedly connected to the mounting frame 22. The adjustment plate 24 is slidably connected to the guide rod 23. The cylinder 25 is fixedly installed on the mounting frame 22 and is drivenly connected to the adjustment plate 24. A groove 241 is provided on the side of the adjusting plate 24 near the main roller 11 of the rolling mill 1. The connecting rod 26 is slidably connected to the groove 241. The traveling trolley 27 is fixedly connected to the end of the connecting rod 26 away from the adjusting plate 24. The compression spring 28 is sleeved on the outer ring of the connecting rod 26. One end of the compression spring 28 is fixedly connected to the traveling trolley 27, and the other end of the compression spring 28 is fixedly connected to the adjusting plate 24. The rotating rod 3 is rotatably connected to the traveling trolley 27.

[0036] It should be noted that the fixed end of the electric push rod 6 is rotatably connected to the adjusting plate 24, and the end of the rotating rod 3 away from the measuring carriage 4 is rotatably connected to the traveling carriage 27. The cylinder 25 drives the adjusting plate 24 to move up and down, thereby driving the connecting rod 26, the traveling carriage 27, the compression spring 28, the rotating rod 3, the measuring carriage 4 and the electric push rod 6 to move synchronously, thereby adjusting the height of the measuring carriage 4 and ensuring that the outer wheel 41 is in contact with the outer ring at the bottom of the ring 5 during the measurement process. The electric slide table 21 pushes the mounting frame 22 to move closer to the main roller 11, thereby driving the guide rod 23, adjusting plate 24, cylinder 25, connecting rod 26, traveling trolley 27, compression spring 28, rotating rod 3, measuring trolley 4 and electric push rod 6 to move synchronously until all wheels of the traveling trolley 27 roll and fit against the outer ring of the main roller 11, and the compression spring 28 is compressed; by utilizing the friction between the traveling trolley 27 and the main roller 11, the traveling trolley 27 is not easy to sway up and down, which helps to ensure the stability of the rotating rod 3 and the measuring trolley 4; If the connecting rod 26, the traveling trolley 27, and the compression spring 28 are not provided, and the rotating rod 3 is directly mounted on the adjusting plate 24, in order to ensure that the outer wheel 41 of the measuring trolley 4 can be pressed tightly against the outer ring of the ring 5 by the thrust of the electric push rod 6, the included angle between the rotating rod 3 and the electric push rod 6 cannot be too small. In this case, the adjusting plate 24 needs to be set long enough, which will cause the suspended end of the adjusting plate 24 to wobble easily, affecting the stability of the measuring trolley 4. This invention avoids the up-and-down swaying of the traveling trolley 27 by utilizing the vertical friction between the wheels of the traveling trolley 27 and the main roller 11, thus ensuring the stability of the measuring trolley 4 and helping to ensure the accuracy and reliability of the outer diameter measurement of the ring 5.

[0037] In this embodiment, the main roller 11 is radially fed. The main roller 11 is rotatably mounted on the roller seat 13. The roller seat 13 is slidably connected to the frame 15 of the ring rolling machine 1. The ring rolling machine 1 drives the roller seat 13 to move through the hydraulic cylinder 14, thereby driving the main roller 11 to perform radial feed. The adjustment assembly 2 also includes a guide rail 20 and a slider. The guide rail 20 is fixedly mounted on the ground. The slider is slidably connected to the guide rail 20. The electric slide table 21 is fixedly mounted on the top of the slider. The length direction of the guide rail 20 is parallel to the feed direction of the main roller 11. Two baffles 16 are fixedly mounted on the side of the roller seat 13 near the mounting frame 22. The mounting frame 22 is sandwiched between the two baffles 16. The sides of the two baffles 16 that are close to each other are in contact with the mounting frame 22. The movement of the roller seat 13 drives the two baffles 16 to move, thereby driving the mounting frame 22 to move synchronously. During this process, the electric slide table 21 slides on the guide rail 20, thereby ensuring that the wheels of the traveling trolley 27 are stably in contact with the main roller 11.

[0038] It is important to emphasize that during the rolling process of the ring 5, the output end of the electric push rod 6 is adaptively shortened. Specifically, the two ends of the electric push rod 6 are rotatably connected to the adjusting plate 24 and the rotating rod 3 through two rotating seats. A pressure sensor is set between the output end of the electric push rod 6 and the corresponding rotating seat. When the diameter of the ring 5 increases, the pressure sensor is compressed. When the pressure exceeds the preset value, the output end of the electric push rod 6 shortens, so that the pressure value detected by the pressure sensor is always kept within the preset range. This ensures the calculation while avoiding excessive pressure between the outer wheel 41 and the ring 5, which could damage the outer wheel 41.

[0039] Example 4: As an optimization of Example 3, such as Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a fixing bracket 242 is fixedly installed on the adjusting plate 24. A spray gun 29 is fixedly installed on the end of the fixing bracket 242 away from the adjusting plate 24. The measuring carriage 4 has an air hole 46 corresponding to the spray gun 29. The air hole 46 is connected to the cavity 42.

[0040] It should be noted that the high-temperature gas around the ring 5 will enter the cavity 42. The spray gun 29 is used to inject cold air into the cavity 42 through the air hole 46, thereby cooling the internal space of the cavity 42 and ensuring the stable operation of the rotary encoder 44. Specifically, the measurement of the outer diameter of the ring 5 by the measuring carriage 4 is intermittent, with a preset time interval between two adjacent measurements. During the measurement, the electric push rod 6 pushes the rotating rod 3, and all the outer wheels 41 of the measuring carriage 4 are in contact with the outer ring of the ring 5. After the measurement is completed, the electric push rod 6 drives the rotating rod 3 to reset. At this time, the spray gun 29 is inserted into the air hole 46 and sprays a preset volume of cold air to cool the cavity 42. Through the intermittent measurement and the design of the spray gun 29, the service life of the diameter measuring mechanism is greatly improved.

[0041] Example 5: As an optimization of Example 4, such as Figure 3 , Figure 7 , Figure 8 and Figure 10 As shown, a first fixing ring 31 is fixedly installed on the rotating rod 3, and a second fixing ring 47 is fixedly installed on the measuring trolley 4. The first fixing ring 31 and the second fixing ring 47 are connected by a tension spring 7.

[0042] It should be noted that by setting the tension spring 7, a continuous and stable elastic tension force can be formed on the measuring carriage 4, which effectively restricts the free swaying and disordered rotation of the measuring carriage 4, and ensures the positional stability of the measuring carriage 4 in its natural state. This ensures that when the electric push rod 6 pushes the rotating rod 3 to rotate towards the ring 5, all the outer wheels 41 of the measuring carriage 4 can fit against the outer ring of the ring 5. Specifically, during the process of measuring the trolley 4 approaching the ring 5, two of the outer wheels 41 of the measuring trolley 4 that are away from the second fixed ring 47 first come into contact with the outer ring of the ring 5. Under the continued push of the electric push rod 6, the measuring trolley 4 rotates, the distance between the second fixed ring 47 and the first fixed ring 31 increases, the tension spring 7 is stretched, and the other two outer wheels 41 of the measuring trolley 4 that are close to the second fixed ring 47 come into contact with the outer ring of the ring 5. In addition, the design of the tension spring 7 helps to ensure that all the outer wheels 41 of the measuring carriage 4 remain in contact with the outer ring of the ring 5 during the rolling process of the ring 5, thereby helping to ensure the accuracy of the measurement.

[0043] Example 6: As an optimization of Example 5, such as Figure 6 , Figure 9 and Figure 10 As shown, a digital universal angle gauge 8 is installed on the adjusting plate 24, a guide sleeve 32 is fixedly connected to the rotating rod 3, the fixed arm 81 of the digital universal angle gauge 8 is fixedly connected to the adjusting plate 24, and the movable arm 82 of the digital universal angle gauge 8 is slidably sleeved with the guide sleeve 32.

[0044] It should be noted that the fixed arm 81 is fixedly connected to the adjusting plate 24 via the connecting arm 243, the connecting arm 243 is fixedly connected to the adjusting plate 24, the fixed arm 81 is fixedly installed on the connecting arm 243, and the length direction of the fixed arm 81 is parallel to the length direction of the connecting rod 26. Under the guidance of the guide sleeve 32, the length direction of the movable arm 82 remains parallel to the length direction of the rotating rod 3. The digital universal angle gauge 8 is used to detect the angle between the connecting rod 26 and the rotating rod 3 in real time. During the rolling and expanding process of ring 5, the outer diameter of ring 5 continues to expand, which will drive the rotating rod 3 to deflect slowly. The angle between the connecting rod 26 and the rotating rod 3 can be detected in real time by the digital universal angle gauge 8. When the angle detected by the digital universal angle gauge 8 reaches the preset value, it means that the size of ring 5 is close to the standard size of rolling and expanding. The rolling machine 1 automatically slows down the feed speed of rolling and expanding and adopts a low-speed fine rolling mode to complete the finishing process, so as to accurately calculate the outer diameter of ring 5 and ensure the rolling and expanding accuracy of ring 5.

[0045] In this embodiment, two sets of diameter measuring mechanisms are mirrored about the symmetrical plane of the ring rolling machine 1. The two sets of symmetrically arranged diameter measuring mechanisms can simultaneously measure the outer rings on both sides of the ring 5. During the rolling and expansion process, two sets of outer diameter measurement data are collected simultaneously, and the two sets of data are compared and the average value is calculated. This helps to avoid measurement deviations caused by local deformation and single-point detection errors in unilateral measurement, and further ensures the accuracy of the rolling and expansion process.

[0046] Example 7: As an optimization of Example 6, such as Figure 1 , Figure 11 and Figure 12 As shown, an adjustment unit 91 is installed on the frame 15 of the ring rolling machine 1. A laser head 92 and a first sensor 93 are fixedly installed at the output end of the bottom of the adjustment unit 91. The laser head 92 and the first sensor 93 are both located between the main roller 11 and the core roller 12 of the ring rolling machine 1. The laser head 92 is used to make marking holes on the ring 5, and the first sensor 93 is used to detect the marking holes.

[0047] It should be noted that the laser head 92 is used to make marking holes on the top end face of the aluminum alloy ring 5. The marking holes can be set to easily identifiable hole shapes such as round holes or oblong holes according to the detection requirements of the first sensor 93, so as to ensure that the first sensor 93 can accurately identify the marking holes. The first sensor 93 preferably adopts a diffuse reflection photoelectric sensor, specifically the HG-C1100L3-P type photoelectric sensor. This sensor has the characteristics of strong light interference resistance, high detection accuracy and fast response speed, which helps to ensure the accuracy of the calculation. When the ring 5 rotates with the main roller 11, the first sensor 93 continuously scans the top and end faces of the ring 5. When the marked hole processed by the laser head 92 is detected twice, it can be determined that the ring 5 has rotated a full circle. During the time period of the marked holes detected on both sides, the average number of pulse signals output by the rotary encoder 44 is the P value used for calculation. The precise calibration of the number of rotations of the ring 5 is achieved through the cooperation of the laser head 92 and the first sensor 93, which is conducive to further improving the accuracy of the outer diameter measurement of the ring 5.

[0048] Example 8: As an optimization of Example 7, such as Figure 11 and Figure 12 As shown, a second sensor 94 is also fixedly installed at the output end of the adjustment part 91. The second sensor 94 is used to monitor the distance between itself and the top surface of the ring 5. The second sensor 94 is also used to detect the depth of the marking hole.

[0049] It should be noted that during the initial rolling process, the laser head 92, the first sensor 93, and the second sensor 94 are all at a suitable working height. When only the ring 5 is radially rolled, the height and diameter of the ring 5 will increase. When only the ring 5 is axially rolled, the height of the ring 5 will decrease and the diameter will increase. That is, during the rolling process, the height of the top surface of the ring 5 will change, which will lead to the laser head 92, the first sensor 93, and the second sensor 94 being at a suitable working height. The second sensor 94 is electrically connected to the adjustment unit 91. The second sensor 94 collects the distance data between itself and the top surface of the ring 5 in real time, providing data basis for the adjustment unit 91 to adjust the height of the laser head 92, the first sensor 93 and the second sensor 94, ensuring that the three are always within the optimal working range and avoiding detection failure due to changes in the height of the ring 5 during the rolling process. Furthermore, during the rolling and expanding process of the ring 5, the marking holes on the top surface of the ring 5 will be rolled and squeezed, resulting in shallower hole depths, blurred hole shapes, or even disappearance. This affects the first sensor 93's recognition of the marking holes and causes errors in the counting of the number of rings. The second sensor 94 detects the depth of the marking holes. When the hole depth detection value is lower than the preset value, the second sensor 94 transmits an electrical signal to the laser head 92. The laser head 92 then re-drills a hole at the original marking hole position, deepening and clarifying the marking hole. This ensures that the first sensor 93 can clearly identify and detect the marking hole, guaranteeing the accuracy and reliability of the calculation.

[0050] In this embodiment, the second sensor 94 is preferably an SCI20011 type spectral confocal displacement sensor, which has high-precision non-contact ranging and micro-deformation detection capabilities, and can meet the depth detection requirements of the marking hole.

[0051] Example 9: As an optimization of Example 8, such as Figure 1 , Figure 11 and Figure 12 As shown, the adjustment unit 91 includes a first servo electric cylinder 911 and an adjustment frame 912. The first servo electric cylinder 911 is fixedly installed on the frame 15. The adjustment frame 912 is connected to the first servo motor for vertical drive and is slidably connected to the frame 15. The laser head 92, the first sensor 93 and the second sensor 94 are all fixedly installed at the bottom of the adjustment frame 912.

[0052] It should be noted that by using the first servo electric cylinder 911 to drive the adjustment frame 912 to move up and down, the overall height of the bottom laser head 92, the first sensor 93, and the second sensor 94 can be adjusted synchronously. This can adapt to the processing requirements of semiconductor aluminum alloy rings 5 ​​with different thicknesses and specifications. At the same time, the height of the laser head 92, the first sensor 93, and the second sensor 94 can be adjusted in real time according to the detection data of the second sensor 94, so that the three are always in the optimal working position.

[0053] In this embodiment, the laser head 92, the first sensor 93, and the second sensor 94 are respectively fixedly mounted on the bottom of the adjustment frame 912 by independent and detachable mounting bases 913. Each mounting base 913 is fixed to the bottom of the adjustment frame 912 by bolts. Since the optimal working positions of the laser head 92, the first sensor 93, and the second sensor 94 are different, by setting mounting bases 913 of different heights, after the height of the adjustment frame 912 is fixed, the laser head 92, the first sensor 93, and the second sensor 94 can all be in their respective optimal working positions. In addition, the laser head 92, the first sensor 93, and the second sensor 94 are all fixedly mounted on their respective mounting bases 913 by bolts to facilitate maintenance and replacement.

[0054] Example 10: A method of using a semiconductor aluminum alloy ring rolling dimension measuring device includes the following steps: S1. Place the ring 5 to be processed on the outer ring of the core roller 12; S2. The electric slide table 21 drives the traveling trolley 27 to move closer to the main roller 11 until the wheels of the traveling trolley 27 are in contact with the outer ring of the main roller 11. S3, the ring rolling machine 1 performs rolling and expanding operations on the ring 5; S4. The diameter measuring mechanism intermittently measures the outer diameter of ring 5; S5. When the outer diameter of the ring 5 is within the preset range, stop the rolling operation and remove the processed ring 5.

[0055] It should be noted that S4 includes the following steps: S41, the electric push rod 6 pushes the rotating rod 3 to rotate towards the ring 5 until all the outer wheels 41 of the measuring trolley 4 are in contact with the outer ring of the ring 5; S42. Calculate the outer diameter of the ring 5 using the measuring trolley 4. S43, the electric push rod 6 drives the rotating rod 3 to reset, and the spray gun 29 is inserted into the air hole 46 to cool the cavity 42; S44, Repeat S41-S43.

[0056] In S42, when the digital universal angle gauge 8 detects that the angle has reached the preset value, the feed speed of the main roller 11 is slowed down. In addition, when the calculated outer diameter exceeds the preset value, it can also be used as a basis for slowing down the feed speed of the main roller 11. The angle detected by the digital universal angle gauge 8 is given priority as the basis. When the digital universal angle gauge 8 is faulty or damaged, the calculated outer diameter can be used as the basis. The dual protection ensures the improved adaptability of the equipment.
