Description

Technical Field

[0001] This invention relates to the field of machinery, and more specifically, to a multi-point non-destructive straightening device and method. Background Technology

[0002] Due to their shape, long shaft parts are prone to bending deformation during prolonged use, affecting their normal operation. For example, lead screws are high-precision, slender, flexible shaft parts whose main function is to convert rotary motion into linear motion or torque into axial reciprocating force. Therefore, they have high requirements for precision, strength, and wear resistance. During machining or heat treatment, the combined effects of cutting force, centrifugal force, self-weight, and heat can cause the lead screw to bend and deform, affecting its use. Therefore, it is necessary to straighten the bending deformation of shaft-type products to ensure their straightness meets certain requirements for normal operation.

[0003] However, there is a problem in the straightening process: traditional straightening methods generally use multiple straightening rollers or cylinders for straightening, such as patents CN209736378U and CN213079609U. These methods involve direct contact between the non-destructive straightening device and the long shaft part. During this process, the friction generated by the non-destructive straightening device is very likely to cause scratches and wear on the long shaft part. Even if the straightness of the long shaft part meets the usage requirements, the damaged parts will affect the normal function of the entire long shaft part, and in severe cases, it will lead to direct scrapping. Summary of the Invention

[0004] Therefore, the present invention provides a multi-point non-destructive straightening device and method, which solves the problem of scratches and wear on long shaft parts caused by direct contact between the straightening device and the long shaft parts during the straightening process.

[0005] To address the aforementioned problems, this invention provides a multi-point non-destructive straightening device for non-destructive straightening of long shaft parts. The device includes: a frame comprising a base plate and two moving components mounted on the base plate; a detection component mounted on the frame for detecting the deformation of the long shaft part; a heating component mounted on the frame for heating the detected long shaft part; and a straightening component mounted on the frame for straightening the heated long shaft part. The moving components drive the long shaft part to move between the detection component, heating component, and straightening component, with the heating component positioned between the detection component and the straightening component.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The multi-point non-destructive straightening device includes a frame, a detection component, a heating component, and a straightening component. The frame includes a base plate and two moving components. The detection component, heating component, straightening component, and two moving components are all located on the base plate. The detection component and straightening component are placed adjacent to the heating component. The heating component is located between the detection component and the straightening component. The two ends of the long shaft part can be fixed on the moving components. The moving components are used to drive the long shaft part to move between the detection component, the heating component, and the straightening component.

[0007] When the multi-point non-destructive straightening device starts working, both ends of the long shaft part are fixed to the moving assembly. When the moving assembly moves the long shaft part to the detection assembly, multiple pressure sensors on the detection assembly begin to detect the deformation of the long shaft part. By monitoring the changes in the pressure sensor values, the deformation of the long shaft part at the pressure sensor is calculated. After the deformation of the long shaft part is detected, the moving assembly moves the long shaft part to the heating assembly. Multiple induction coils on the heating assembly quickly heat the deformed area of ​​the long shaft part. After the deformed area of ​​the long shaft part is heated, the heated long shaft part is quickly moved above the straightening assembly, where a cooling cylinder quickly immerses the long shaft part in the coolant. Through the principle of quenching, the long shaft part is straightened. During the straightening process, the long shaft part is in contact with the coolant; in the remaining processes, only the two ends of the long shaft part are in contact with the moving assembly, thus achieving a non-destructive straightening effect.

[0008] In one embodiment of the present invention, the detection component includes: a first fixed base disposed on a base plate; a plurality of first lifting mechanisms disposed between the base plate and the first fixed base; a first guide rail disposed on the first fixed base; and a plurality of detection devices disposed on the first guide rail; wherein the detection devices are used to detect the deformation of the long shaft part, and the detection devices are capable of moving axially along the first guide rail.

[0009] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: A first lifting mechanism is provided on the base plate, and the first lifting mechanism is located between the base plate and the first fixed seat. The first lifting mechanism can lift the first fixed seat and adjust the height of the detection component according to the diameter of the long shaft part. By adjusting the height of the detection component, contact between the detection component and long shaft parts of different diameters can be avoided. A first guide rail is provided on the first fixed seat, and multiple detection devices are provided on the first guide rail. The detection devices can move axially along the length direction of the long shaft part on the first guide rail. By setting multiple movable detection devices, the detection efficiency can be improved and the overall straightening time can be saved.

[0010] In one embodiment of the present invention, the detection device is provided with multiple pressure sensors, and the pressure sensors are evenly distributed.

[0011] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: each detection device is equipped with multiple pressure sensors, each of which can detect the deformation of long shaft parts. Setting multiple pressure sensors can further improve detection efficiency and increase the accuracy and precision of detection. The uniform distribution of pressure sensors keeps the detection time at the same rate, which can further improve detection efficiency.

[0012] In one embodiment of the present invention, the heating assembly includes: a second fixed base disposed on a base plate; a plurality of second lifting mechanisms disposed between the base plate and the second fixed base; a second guide rail disposed on the second fixed base; and a plurality of heating devices disposed on the second guide rail, wherein the heating devices are used to heat the long shaft parts; wherein the heating devices are used to heat the long shaft parts and are axially movable along the second guide rail.

[0013] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: A second lifting mechanism is provided on the base plate, and the second lifting mechanism is located between the base plate and the second fixed seat. The second lifting mechanism can lift the second fixed seat, and the height of the heating component can be adjusted according to the diameter of the long shaft part. By adjusting the height of the heating component, contact between the heating component and long shaft parts of different diameters can be avoided. A second guide rail is provided on the second fixed seat, and multiple heating devices are provided on the second guide rail. The heating devices can move axially along the length direction of the long shaft part on the second guide rail. By setting multiple movable heating devices, the heating efficiency can be improved and the overall straightening time can be saved.

[0014] In one embodiment of the present invention, the heating device includes: a second base; a second fixing block fixed to the second base; a first gear fixed to the second fixing block; a second gear fixed to the second fixing block, the second gear meshing with the upper end of the first gear, the second gear having a second cavity in the middle for accommodating a long shaft part, and the second gear having an inner surface; and a plurality of induction coils disposed on the inner surface, and the induction coils being evenly distributed.

[0015] Compared with the prior art, the technical effects achieved by this technical solution are as follows: The second base is mounted on the second guide rail and is used to move on the second guide rail. The second base also supports and fixes the second fixing block. The second fixing block is equipped with a first gear and a second gear, which mesh with the first gear. The rotation of the first gear drives the rotation of the second gear. There is a second cavity in the middle of the second gear, and a second opening is provided on the second gear. The second opening is used to allow the long shaft part to enter the second cavity, providing an entrance and exit for the long shaft part to enter and leave the second cavity. The second cavity is used to accommodate the long shaft part. Furthermore, there is an inner surface on the second gear, and multiple induction coils are mounted on the inner surface. Each induction coil can perform high-frequency induction heating on the deformed part. The heating device is equipped with multiple induction coils to further ensure precise heating of the deformed part. The heating parameters of the multiple induction coils can be controlled individually. In this invention, multiple heating devices are provided, and the heating devices can move along the axial direction of the long shaft part. The number of heating devices corresponds to the number of straightening positions in a single operation.

[0016] In one embodiment of the present invention, the moving component includes: a third fixed block, which is fixed to a base plate; a third guide rail, which is disposed on the third fixed block; a third moving block, which can move on the third guide rail; a third servo motor, which is fixed to the third moving block; and a third turntable holder, which is fixed to the third moving block, and a third pneumatic chuck and a fourth servo motor are fixed on the third turntable holder; wherein the third pneumatic chuck is used to clamp either end of the long shaft part, and the fourth servo motor is used to drive the long shaft part to rotate.

[0017] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: The moving component includes a third fixed block, which supports the third guide rail and other structures, and provides a height for the multi-point non-destructive straightening device. The third guide rail is mounted on the third fixed block, providing a stable linear environment for the movement of the third moving block. The third moving block is used to connect and fix the third servo motor and the third turntable chuck. The third servo motor provides power for the movement of the third moving block. The third turntable chuck is used to connect and fix the third pneumatic chuck and the fourth servo motor. The third pneumatic chuck is used to clamp any end of the long shaft part, and the fourth servo motor provides power for the rotation of the long shaft part.

[0018] In one embodiment of the present invention, a fourth guide rail is also provided on the base plate, and any moving component is capable of moving axially along the fourth guide rail.

[0019] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: a fourth guide rail is also provided on the base plate, and any moving component can move axially along the fourth guide rail. Since the long shaft parts that need to be straightened have different lengths, any moving component can move axially along the length direction of the fourth guide rail and the long shaft parts to accommodate the use of different long shaft parts and improve the usability of the multi-point non-destructive straightening device.

[0020] In one embodiment of the present invention, the straightening assembly includes: a cooling tank disposed on a base plate; and a cooling cylinder disposed in the cooling tank, at least a portion of which is disposed within the cooling tank.

[0021] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: The straightening component includes a cooling tank, which is fixed on the base plate and contains coolant for cooling the heated long shaft parts; the straightening component also includes a cooling cylinder, which supports the long shaft parts and is used to quickly immerse the long shaft parts in the coolant and remove them from the coolant.

[0022] In one embodiment of the present invention, the present invention also provides a control method for a multi-point non-destructive straightening device, wherein the control method for the multi-point non-destructive straightening device includes:

[0023] Step S100: The detection component detects the deformation of the long shaft part and obtains the deformation curve.

[0024] Step S200: Based on the deformation curve, determine the required heating temperature and heating area for the long shaft part, and move the long shaft part to the heating assembly;

[0025] Step S300: The heating assembly heats the long shaft part that has been inspected according to the determined heating temperature and heating area, and moves the long shaft part to the straightening assembly;

[0026] Step S400: The straightening assembly straightens the long shaft parts after heating;

[0027] Step S500: After the straightening is completed, move the long shaft part to the detection component again and perform the detection. If the long shaft part is still deformed, repeat steps S100-S500; if the long shaft part is not deformed, the straightening is completed.

[0028] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the multi-point non-destructive straightening device is working, the two ends of the long shaft part are first fixed to the third pneumatic chuck of the moving assembly. The third servo motor on the moving assembly provides power to the third moving block, which then moves the long shaft part above the detection assembly. Pressure sensors on the detection assembly detect all parts of the long shaft part and obtain its deformation curve. The system determines the deformation points of the long shaft part based on the formed deformation curve, and determines the required heating area and heating temperature. The system makes a heating decision and moves the long shaft part to the heating assembly. The heating assembly performs high-frequency induction heating on the heating area of ​​the long shaft part based on the system's decision. After heating, the long shaft part is moved above the straightening assembly, and a cooling cylinder quickly immerses it in the coolant in the cooling tank for cooling. This process straightens the long shaft part through quenching. After cooling, the long shaft part is removed from the coolant by the cooling cylinder and transported back to the pressure sensor detection area of ​​the detection assembly for re-detection. This process is repeated until the long shaft part is straightened and meets product requirements. This method utilizes rapid heating and then rapid cooling of the deformed protruding section of the long shaft part to release internal stress and eliminate stress imbalances generated during heat treatment, thus achieving a straightening effect. The moving assembly can repeatedly move the long shaft part between the detection assembly, heating assembly, and straightening assembly, improving the accuracy of straightening through multiple detection-heating-straightening steps.

[0029] In one embodiment of the present invention, the required heating temperature and heating area of ​​the long shaft part are determined according to the deformation curve, and the long shaft part is moved to the heating assembly, including:

[0030] Step S210: Select multiple locations with the largest deformation on the long shaft part according to the deformation curve diagram;

[0031] Step S220: Calculate the required heating temperature and heating area for the location;

[0032] Step S230: Move the long shaft part to the heating assembly.

[0033] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: The required heating temperature and heating area for the long shaft part are determined, and during the process of moving the long shaft part to the heating assembly, the positions with the largest deformation on the long shaft part are selected, and the required heating temperature and heating area for these positions are calculated. Prioritizing the heating of the positions with the largest deformation allows for the overall straightening of the long shaft part, followed by detailed straightening, thus improving straightening efficiency.

[0034] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0035] (1) Non-destructive straightening, without contacting or damaging long shaft parts during the straightening process;

[0036] (2) Multi-point straightening improves straightening efficiency;

[0037] (3) The straightening amount of long shaft parts can be adjusted independently, and it can be used to straighten long shaft parts of different diameters / lengths;

[0038] (4) The moving component can drive the long shaft parts to move repeatedly between the detection component, heating component, and straightening component. Through multiple detection-heating-straightening steps, the accuracy of straightening is improved.

[0039] (5) By rapidly heating and then rapidly cooling the deformed protruding section of the long shaft part, the internal stress is released and the internal stress imbalance generated during the heat treatment process is eliminated. Attached Figure Description

Detailed Implementation

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example 1

[0052] See Figures 1-7 In one specific embodiment, the multi-point non-destructive straightening device includes: a frame 400, which includes a base plate 410 and two moving components 420, the moving components 420 being disposed on the base plate 410; a detection component 100, which is disposed on the frame 400 and is used to detect the deformation of the long shaft part 500; a heating component 200, which is disposed on the frame 400 and is used to heat the detected long shaft part 500; and a straightening component 300, which is disposed on the frame 400 and is used to straighten the heated long shaft part 500; wherein, the moving components 420 are used to drive the long shaft part 500 to move between the detection component 100, the heating component 200 and the straightening component 300, and the heating component 200 is disposed between the detection component 100 and the straightening component 300.

[0053] Specifically, the multi-point non-destructive straightening device includes a frame 400, a detection component 100, a heating component 200, and a straightening component 300. The frame 400 includes a base plate 410 and two moving components 420. The detection component 100, the heating component 200, the straightening component 300, and the two moving components 420 are all mounted on the base plate 410. The detection component 100 and the straightening component 300 are placed adjacent to the heating component 200. The heating component 200 is located between the detection component 100 and the straightening component 300. The two ends of the long shaft part 500 can be fixed on the moving components 420. The moving components 420 are used to drive the long shaft part 500 to move between the detection component 100, the heating component 200, and the straightening component 300.

[0054] When the multi-point non-destructive straightening device starts working, according to the length of the long shaft part 500, the two moving components 420 are moved to the appropriate position and fixed, so that the two ends of the long shaft part 500 are respectively fixed on the third pneumatic chuck 426 of the moving component 420, and the third servo motor 424 on the moving component 420 provides a power for the movement of the moving component 420.

[0055] When the moving component 420 moves the long shaft part 500 to the detection component 100, the first elevator 120 at the detection component 100 lifts and lowers according to the diameter of the long shaft part 500, adjusting the detection component 100 to a suitable height (it stops when the distance between the plane of the pressure sensor 141 and the center of the third pneumatic chuck 426 is slightly higher than the radius of the long shaft part 500). At the same time, the fourth servo motor 427 on the moving component 420 starts running and drives the long shaft part 500 to rotate. At this time, the multiple pressure sensors 141 on the detection component 100 can detect all parts of the long shaft part 500.

[0056] By monitoring the changes in the pressure sensor 141, the deformation of the long shaft part 500 at the pressure sensor 141 is calculated, forming a deformation curve. After the deformation of the long shaft part 500 is detected, the system selects several locations with the largest deformation based on the deformation curve (generally 1-8 locations are selected based on the deformation area of ​​the long shaft part 500), and determines the required heating area and heating temperature. The moving component 420 moves the long shaft part 500 to the heating component 200. The heating component 200 is equipped with multiple heating devices 240, which can simultaneously perform high-frequency induction heating on different heating areas of the long shaft part 500 according to system requirements. Multiple induction coils on the heating devices 240 Induction coil 252 rapidly heats the deformed area of ​​long shaft part 500. Induction coil 252 can also operate independently to facilitate heating different circumferential positions of long shaft part 500. After heating the deformed area, the heated long shaft part 500 is quickly moved above the straightening assembly 300. Cooling cylinder 320 quickly immerses the long shaft part 500 in coolant, straightening it through quenching. After cooling, the long shaft part 500 is removed from the coolant by cooling cylinder 320 and transported back to the detection area of ​​pressure sensor 141 in detection assembly 100 for re-detection. This process is repeated until the long shaft part 500 is straightened and meets product requirements. During the straightening process, the long shaft part 500 is in contact with the coolant. In the remaining processes, only the two ends of the long shaft part 500 contact the moving assembly 420, achieving a non-destructive straightening effect.

[0057] See Figure 2 In one specific embodiment, the detection component 100 includes: a first fixed base 110 disposed on a base plate 410; a plurality of first lifts 120 disposed between the base plate 410 and the first fixed base 110; a first guide rail 130 disposed on the first fixed base 110; and a plurality of detection devices 140 disposed on the first guide rail 130. The detection devices 140 are used to detect the deformation of the long shaft part 500, and are axially movable along the first guide rail 130.

[0058] Specifically, the detection assembly 100 includes a first fixed base 110, multiple first lifts 120, a first guide rail 130, and multiple detection devices 140. The first lifts 120 are mounted on the base plate 410 and positioned between the base plate 410 and the first fixed base 110. The first lifts 120 can lift the first fixed base 110, allowing the height of the detection assembly 100 to be adjusted according to the diameter of the long shaft part 500. Adjusting the height of the detection assembly 100 prevents it from contacting long shaft parts 500 of different diameters. The first fixed base 110 is equipped with the first guide rail 130, and multiple detection devices 140 are mounted on the first guide rail 130. The detection devices 140 can move axially along the length of the long shaft part 500 on the first guide rail 130. By providing multiple movable detection devices 140, detection efficiency can be improved, and overall straightening time can be saved.

[0059] Preferably, in order to improve detection efficiency and save detection time, the detection device 140 can be set to 4 or more.

[0060] In one specific embodiment, the detection device 140 is provided with a plurality of pressure sensors 141, and the pressure sensors 141 are evenly distributed.

[0061] Furthermore, each detection device 140 is equipped with multiple pressure sensors 141, each of which can detect the deformation of the long shaft part 500. Setting multiple pressure sensors 141 can further improve detection efficiency and increase detection accuracy and precision. The even distribution of pressure sensors 141 keeps the detection time at the same rate, which can further improve detection efficiency.

[0062] Preferably, in order to better improve detection efficiency and accuracy, the pressure sensor 141 can be set to 20 or more.

[0064] Specifically, the heating assembly 200 includes a second fixed base 210, multiple second lifts 220, a second guide rail 230, and multiple heating devices 240. The second lifts 220 are mounted on the base plate 410 and positioned between the base plate 410 and the second fixed base 210. The second lifts 220 can lift the second fixed base 210, allowing the height of the heating assembly 200 to be adjusted according to the diameter of the long shaft part 500. Adjusting the height of the heating assembly 200 prevents it from contacting long shaft parts 500 of different diameters. The second fixed base 210 is equipped with the second guide rail 230, and multiple heating devices 240 are mounted on the second guide rail 230. The heating devices 240 can move axially along the length of the long shaft part 500 on the second guide rail 230. By providing multiple movable heating devices 240, heating efficiency can be improved, and overall straightening time can be saved.

[0067] Furthermore, the heating device 240 includes a second base 241, a second fixing block 242, a first gear 243, a second gear 250, and multiple induction coils 252.

The second fixing block 242 is provided with the first gear 243 and the second gear 250. The second gear 250 meshes with the first gear 243. The rotation of the first gear 243 drives the rotation of the second gear 250. The second gear 250 has a second cavity in the middle and a second opening on it. The second opening is used to allow the long shaft part 500 to enter the second cavity, providing an entrance and an exit for the long shaft part 500 to enter and leave the second cavity. The second cavity is used to accommodate the long shaft part 500. Furthermore, an inner surface 251 exists on the second gear 250, and multiple induction coils 252 are disposed on the inner surface 251. Each induction coil 252 can perform high-frequency induction heating on the deformed part of the long shaft part 500. The setting of multiple induction coils 252 can further improve the heating efficiency. The uniform distribution of the induction coils 252 can make the long shaft part 500 heat up more evenly.

[0068] Preferably, in order to better improve heating efficiency, the induction coil 252 can be set to 5 or more.

[0070] Furthermore, the moving component 420 includes a third fixed block 421, which supports the third guide rail 422 and other structures, and provides a height for the multi-point non-destructive straightening device. The third guide rail 422 is mounted on the third fixed block 421, providing a stable linear environment for the movement of the third moving block 423. The third moving block 423 is used to connect and fix the third servo motor 424 and the third turntable chuck 425.

The third pneumatic chuck 426 is used to clamp any end of the long shaft part 500, and the fourth servo motor 427 provides power for the rotation of the long shaft part 500.

[0071] In one specific embodiment, the base plate 410 is further provided with a fourth guide rail 430, and any moving component 420 is capable of moving axially along the fourth guide rail 430.

[0072] Furthermore, a fourth guide rail 430 is provided on the base plate 410, and any moving component 420 can move axially along the fourth guide rail 430. Since the long shaft parts 500 that need to be straightened have different lengths, any moving component 420 can move axially along the fourth guide rail 430 and the length direction of the long shaft parts 500 to accommodate different long shaft parts 500 and improve the usability of the multi-point non-destructive straightening device.

[0073] See Figure 7 In one specific embodiment, the straightening component 300 includes: a cooling tank 310 disposed on a base plate 410; and a cooling cylinder 320 disposed in the cooling tank 310, at least a portion of which is disposed within the cooling tank 310.

[0074] Furthermore, the straightening assembly 300 includes a cooling tank 310, which is fixed to the base plate 410 and contains coolant for cooling the heated long shaft part 500; the straightening assembly 300 also includes a cooling cylinder 320, which supports the long shaft part 500 and is used to quickly immerse the long shaft part 500 in the coolant and remove the long shaft part 500 from the coolant.

Example 2

[0076] See Figure 8 In one specific embodiment, the present invention also provides a control method for a multi-point non-destructive straightening device, which controls the multi-point non-destructive straightening device. The control method for the multi-point non-destructive straightening device includes:

[0077] Step S100: The detection component 100 detects the deformation of the long shaft part 500 and obtains the deformation curve.

[0078] Step S200: Based on the deformation curve, determine the required heating temperature and heating area for the long shaft part 500, and move the long shaft part 500 to the heating assembly 200;

[0079] Step S300: The heating assembly 200 heats the long shaft part 500 that has been inspected according to the determined heating temperature and heating area, and moves the long shaft part 500 to the straightening assembly 300;

[0080] Step S400: The straightening assembly 300 straightens the heated long shaft part 500;

[0081] Step S500: After the straightening is completed, move the long shaft part 500 to the detection component 100 again and perform the detection. If the long shaft part 500 is still deformed, repeat steps S100-S500; if the long shaft part 500 is not deformed, the straightening is completed.

[0082] Specifically, when the multi-point non-destructive straightening device is working, the two ends of the long shaft part 500 are first fixed on the third pneumatic chuck 426 of the moving assembly 420. The third servo motor 424 on the moving assembly 420 provides power to the third moving block 423. The third moving block 423 drives the long shaft part 500 to move the long shaft part 500 above the detection assembly 100. The pressure sensor 141 on the detection assembly 100 detects all parts of the long shaft part 500 and obtains the deformation curve of the long shaft part 500. The system determines the deformation location of the long shaft part 500 based on the formed deformation curve, and determines the required heating area and heating temperature, forming a heating decision. At the same time, the long shaft part 500 is moved to the top of the detection assembly 100. Part 500 is moved to heating assembly 200; heating assembly 200 performs high-frequency induction heating on the heating area of ​​long shaft part 500 according to the decision provided by the system; after heating, long shaft part 500 is moved above straightening assembly 300, and cooling cylinder 320 quickly immerses long shaft part 500 in coolant in cooling tank 310 to cool it. Through the principle of quenching, long shaft part 500 is straightened. After cooling, long shaft part 500 is carried out of coolant by cooling cylinder 320 and transported back to the detection area of ​​pressure sensor 141 of detection assembly 100 for detection again. The above steps S are repeated until long shaft part 500 is straightened and meets product requirements. This method utilizes rapid heating and then rapid cooling of the deformed protruding section of long shaft part 500 to release internal stress and eliminate the stress imbalance generated during heat treatment, thereby achieving the straightening effect. The moving component can drive the long shaft parts to move repeatedly between the detection component, heating component, and straightening component. Through multiple detection-heating-straightening steps, the accuracy of straightening is improved.

[0083] In one specific embodiment, based on the deformation curve, the required heating temperature and heating area of ​​the long shaft part 500 are determined, and the long shaft part 500 is moved to the heating assembly 200, including:

[0084] Step S210: Select the multiple positions with the largest deformation on the long shaft part 500 according to the deformation curve diagram;

[0085] Step S220: Calculate the required heating temperature and heating area for the location;

[0086] Step S230: Move the long shaft part 500 to the heating assembly 200.

[0087] Specifically, the required heating temperature and heating area of ​​the long shaft part 500 are determined, and during the process of moving the long shaft part 500 to the heating assembly 200, the positions with the largest deformation on the long shaft part 500 are selected, and the required heating temperature and heating area of ​​these positions are calculated. Prioritizing the heating of the positions with the largest deformation allows for the overall straightening of the long shaft part 500 to be performed first, followed by detailed straightening of the long shaft part 500, thus improving straightening efficiency.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
