[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 3 A quality control inspection device 100 according to an embodiment of the present invention is described. The quality control inspection device 100 is used to detect the quality of a turbine shaft assembly 200. The turbine shaft assembly 200 includes a turbine head 201 and a rotating shaft 202. The turbine head 201 and the rotating shaft 202 can be connected by welding. As some embodiments of the present application, pre-welding can be performed at the welding position of the turbine head 201 and the rotating shaft 202. The pre-welding position is evenly arranged along the circumference of the rotating shaft 202. After the pre-welding is completed, the turbine head 201 and the rotating shaft 202 are continuously welded in the circumference so that the turbine head 201 is fixed to one end of the rotating shaft 202.

[0030] like Figure 1-Figure 3 As shown, according to an embodiment of the present invention, a quality control inspection device 100 for a turbine shaft assembly 200 includes: a base 1, the base 1 is formed with a mounting hole 11 for mounting a rotating shaft 202, and the mounting hole 11 extends along the height direction of the base 1; a first mounting column 2 and an axial swing detection member 3, the first mounting column 2 is fixedly arranged on the base 1, the axial swing detection member 3 is fixedly arranged on the first mounting column 2, and the detection end of the axial swing detection member 3 is used to abut against the surface of the turbine head 201 facing the rotating shaft 202; a second mounting column 4 and a radial displacement detection member 5, the second mounting column 4 is fixedly arranged on the base 1, the radial displacement detection member 5 is arranged on the second mounting column 4, and the detection end of the radial displacement detection member 5 is used to abut against the side of the turbine head 201.

[0031] The base 1 is formed with a mounting hole 11, and the mounting hole 11 extends along the height direction of the quality control inspection device 100. Figure 1 In the up and down direction of the mounting hole 11, the mounting hole 11 is used to mount the rotating shaft 202, so that the turbine shaft assembly 200 is set on the quality control inspection device 100 through the rotating shaft 202, so as to facilitate the inspection of the turbine shaft assembly 200. As some embodiments of the present application, the first mounting column 2 and the base 1 can be integrally formed. As some embodiments of the present application, the first mounting column 2 and the base 1 can be connected by bolts so that the first mounting column 2 is fixed to the base 1.

[0032] As some embodiments of the present application, the axial swing detection member 3 can be constructed as a lever-type dial indicator. The axial swing detection member 3 can have a fixed end and a detection end. The fixed end of the axial swing detection member 3 and the first mounting column 2 can be connected by, but not limited to, bolts, clamping, etc., so that the axial swing detection member 3 is fixed to the first mounting column 2. The detection end of the axial swing detection member 3 can abut against the surface of the turbine head 201 and the surface facing the rotating shaft 202, so that the axial swing detection member 3 can detect the axial side swing of the turbine shaft assembly 200. Qualified turbine shaft assemblies 200 (the axial side swing runout value is less than 0.15 mm) are screened out for subsequent processing, and unqualified turbine shaft assemblies 200 (the axial side swing runout value is greater than or equal to 0.15 mm) are screened out for scrapping.

[0033] As some embodiments of the present application, the second mounting column 4 and the base 1 can be integrally formed. As some embodiments of the present application, the second mounting column 4 and the base 1 can be connected by bolts so that the second mounting column 4 is fixed to the base 1. As some embodiments of the present application, the radial displacement detection member 5 can be constructed as a telescopic dial indicator. The radial displacement detection member 5 can have a fixed end and a detection end, and the fixed end of the radial displacement detection member 5 and the second mounting column 4 can be connected by bolts, clamping, etc., but not limited to, so that the radial displacement detection member 5 is fixed to the second mounting column 4, and the detection end of the radial displacement detection member 5 can be abutted against the side of the turbine head 201, so that the radial displacement detection member 5 can detect the radial eccentricity of the turbine shaft assembly 200, thereby selecting qualified (radial eccentricity runout value is less than 0.15 mm) turbine shaft assembly 200 for subsequent processing, and selecting unqualified (radial eccentricity runout value is greater than or equal to 0.15 mm) turbine shaft assembly 200 for scrapping.

[0034] By promptly scrapping the unqualified turbine shaft assembly 200 in the initial stage after welding, the risk of the unqualified turbine shaft assembly 200 being scrapped due to "overcutting" in the later dynamic balancing stage after unnecessary shaft grinding and fine turning can be reduced, thereby effectively reducing the production cycle and production costs. ("Overcutting" refers specifically to cutting beyond the allowable cutting range, which will eventually lead to a failure mode in which the parts cannot meet the mechanical stress conditions)

[0035] Specifically, the welded turbine shaft assembly 200 is inserted into the quality control inspection device 100, and further, the rotating shaft 202 is inserted into the mounting hole 11 of the quality control inspection device 100, and the detection end of the axial swing detection member 3 is abutted against the surface of the turbine head 201 facing the rotating shaft 202, and the detection end of the radial displacement detection member 5 is abutted against the side of the turbine head 201. Manually and smoothly turn the turbine shaft assembly 200 (at least one circle), during the rotation of the turbine shaft assembly 200, the axial swing detection member 3 can detect the runout value of the axial side swing, and the radial displacement detection member 5 can detect the runout value of the radial eccentricity. The turbine shaft assembly 200 with the runout value of the axial side swing and the runout value of the radial eccentricity both less than 0.15 mm is a qualified part.

[0036] The qualified turbine shaft assemblies 200 screened out are subjected to subsequent production processes such as shaft grinding and precision turning, which is conducive to achieving the production capacity requirement of the turbine shaft assemblies 200 of the production line in the subsequent production stage that the movable rate is greater than or equal to 90%, and can also meet the quality control requirements of the turbine shaft assemblies 200 of the production line in the subsequent production stage that the single dynamic balance value of the turbine shaft assemblies 200 is small and the cutting range does not exceed the standard. The unqualified turbine shaft assemblies 200 screened out are promptly scrapped, which is conducive to reducing the scrap rate of the subsequent turbine shaft assemblies 200 production line (the scrap rate of the qualified turbine shaft assemblies 200 after screening can be controlled within 5% in the subsequent production stage), and can also reduce the final production cycle of a single good turbine shaft assembly 200, for example: the production cycle is within 50 seconds, and the qualified number of good turbine shaft assemblies 200 in a single-shift production line is increased, for example: the qualified number is more than 400.

[0037] Therefore, by setting up the axial swing detection part 3 and the radial displacement detection part 5, the axial side swing and radial eccentricity of the turbine shaft assembly 200 can be detected, so as to screen out qualified (the axial side swing runout value and the radial eccentricity runout value are both less than 0.15 mm) turbine shaft assemblies 200 for subsequent processing, which is beneficial to meet the quality control requirements of the turbine shaft assembly 200 and reduce the scrap rate of the subsequent turbine shaft assembly 200 production line.

[0038] In some embodiments of the present invention, Figure 1 As shown, the first mounting column 2 and the second mounting column 4 are both arranged on the upper surface of the base 1 .

[0039] Among them, the first mounting column 2 and the second mounting column 4 are both arranged on the upper surface of the base 1. Such an arrangement can make the positions of the first mounting column 2 and the second mounting column 4 arranged reasonably. By arranging the first mounting column 2 and the second mounting column 4 on the upper surface of the base 1, the turbine shaft assembly 200 is inserted into the mounting hole 11 from above. The base 1 and the axial swing detection member 3 can support the turbine shaft assembly 200, which can reduce the risk of the turbine shaft assembly 200 falling from the quality control inspection device 100 during the inspection process, which is conducive to improving the safety of the turbine shaft assembly 200 during the inspection process. It is also beneficial for the first mounting column 2 and the second mounting column 4 to be arranged on the same side of the base 1, so that the axial swing detection member 3 installed on the first mounting column 2 and the radial displacement detection member 5 installed on the second mounting column 4 can be arranged on the same side of the base 1, so that the axial swing detection member 3 and the radial displacement detection member 5 can simultaneously detect the axial side swing runout value and the radial eccentric runout value of the turbine shaft assembly 200, respectively, thereby improving the inspection efficiency of the quality control inspection device 100.

[0040] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the first mounting column 2 and the second mounting column 4 are opposite to each other and spaced apart. Along the arrangement direction of the first mounting column 2 and the second mounting column 4 , the mounting hole 11 is located between the first mounting column 2 and the second mounting column 4 .

[0041] Among them, the first mounting column 2 and the second mounting column 4 are arranged opposite to each other, and the first mounting column 2 and the second mounting column 4 are arranged spaced apart. Along the arrangement direction of the first mounting column 2 and the second mounting column 4, the mounting hole 11 is located between the first mounting column 2 and the second mounting column 4. Such an arrangement can make the positions of the mounting hole 11, the first mounting column 2 and the second mounting column 4 reasonably arranged. When the rotating shaft 202 of the turbine shaft assembly 200 is inserted into the mounting hole 11, along the arrangement direction of the first mounting column 2 and the second mounting column 4, the axial swing detection component 3 and the radial displacement detection component 5 can be respectively arranged on both sides of the turbine shaft assembly 200, which is beneficial for the axial swing detection component 3 and the radial displacement detection component 5 to simultaneously detect the axial side swing runout value and the radial eccentricity runout value of the turbine shaft assembly 200 on both sides of the turbine shaft assembly 200, which is beneficial to reduce the risk of the axial swing detection component 3 and the radial displacement detection component 5 interfering with each other due to the close distance between the detection results.

[0042] In some embodiments of the present invention, Figure 3 As shown, the mounting hole 11 penetrates the base 1 along the height direction of the base 1 .

[0043] Among them, the mounting hole 11 passes through the base 1 along the height direction of the base 1. Such a configuration can make the mounting hole 11 reliably avoid the turbine shaft assembly 200. Since the turbine shaft assembly 200 has tolerances during the production process, by making the mounting hole 11 pass through the base 1 along the height direction of the base 1, the risk of the turbine shaft assembly 200 abutting against the base 1 when the tolerances of the turbine shaft assembly 200 are all in the upper tolerance can be reduced, thereby reducing the risk of reduced accuracy or even damage to the turbine shaft assembly 200, which is beneficial to improving the reliability of the turbine shaft assembly 200 during the inspection process.

[0044] In some embodiments of the present invention, Figure 3 As shown, a radial limiting surface 111 is formed on the inner surface of the mounting hole 11 . The radial limiting surface 111 is adjacent to the upper end of the mounting hole 11 . The radial limiting surface 111 is used for abutting against the rotating shaft 202 for limiting.

[0045] Wherein, the rotating shaft 202 may include a neck 205, a large shaft 203 and a small shaft 204. When the turbine shaft assembly 200 is subjected to radial eccentricity detection, the turbine shaft assembly 200 may be subjected to radial eccentricity detection at the large shaft 203 position. When the turbine shaft assembly 200 is subjected to axial sway detection, the axial sway detection may be performed at the junction of the large shaft 203 and the small shaft 204. However, during the detection process, the detection position of the turbine shaft assembly 200 needs to abut against the base 1 to fix the turbine shaft assembly 200, and the working surface of the turbine shaft assembly 200 will inevitably be worn during the rotation of the turbine shaft assembly 200. Therefore, the fixed positions for radial eccentricity detection and axial sway detection are converted from the peripheral wall of the large shaft 203 and the junction of the large shaft 203 and the small shaft 204 to the peripheral wall of the neck 205 and the inclined surface of the neck 205, respectively, and the inclined surface of the neck 205 is connected between the peripheral wall of the neck 205 and the large shaft 203.

[0046] The mounting hole 11 is formed with a radial limit surface 111, and the radial limit surface 111 is formed on the inner surface of the mounting hole 11, and the radial limit surface 111 is adjacent to the upper end of the mounting hole 11. Such a setting can make the position of the radial limit surface 111 reasonably set. When the turbine shaft assembly 200 is assembled on the quality control inspection device 100, it is beneficial to set the radial limit surface 111 at a position corresponding to the peripheral wall of the neck 205, so that the radial limit surface 111 is abutted and limited with the rotating shaft 202, so that in the process of rotating the turbine shaft assembly 200, the radial displacement detection part 5 can smoothly detect the radial eccentricity runout value to detect whether the turbine shaft assembly 200 is qualified, and then screen out qualified turbine shaft assemblies 200 for subsequent processing, which is beneficial to meet the quality control requirements of the turbine shaft assembly 200 and reduce the scrap rate of the subsequent turbine shaft assembly 200 production line.

[0047] It should be noted that when the radial limiting surface 111 abuts against the peripheral wall of the neck 205 for limiting, the peripheral wall of the main shaft 203 and the mounting hole 11 are clearance-matched to reduce the risk of the base 1 wearing the peripheral wall of the main shaft 203, thereby further reducing the risk of scrapping the turbine shaft assembly 200 and improving the detection safety of the turbine shaft assembly 200.

[0048] In some embodiments of the present invention, Figure 3 As shown, the radial limiting surface 111 is annular and extends along the circumference of the mounting hole 11 .

[0049] Among them, the radial limiting surface 111 is annular, and the radial limiting surface 111 extends along the circumference of the mounting hole 11, so that the radial limiting surface 111 has a certain area, which is conducive to the radial limiting surface 111 to reliably limit the turbine shaft assembly 200, and reduce the risk of excessive error in the radial eccentricity of the turbine shaft assembly 200 due to random shaking of the turbine shaft assembly 200, thereby reducing the risk of misjudgment of the quality of the turbine shaft assembly 200 and improving the accuracy of quality screening of the turbine shaft assembly 200.

[0050] In some embodiments of the present invention, Figure 3 As shown, an axial limit bevel 112 is also formed on the inner surface of the mounting hole 11. Along the axial direction of the mounting hole 11, the axial limit bevel 112 is located on the inner side of the radial limit surface 111 and is adjacent to the radial limit surface 111. From the radial limit surface 111 away from the axial limit bevel 112 to the direction close to the axial limit bevel 112, the axial limit bevel 112 is inclined toward the inner side of the mounting hole 11. The axial limit bevel 112 is used to abut and limit with the rotating shaft 202.

[0051] The mounting hole 11 is formed with an axial limiting inclined surface 112, which is formed on the inner surface of the mounting hole 11. Along the axial direction of the mounting hole 11, the axial limiting inclined surface 112 is located inside the radial limiting surface 111, and the axial limiting inclined surface 112 is adjacent to the radial limiting surface 111. The inclination angle and length of the axial limiting inclined surface 112 are adapted to the inclination angle and length of the inclined surface of the neck 205.

[0052] Specifically, from the radial limit surface 111 away from the axial limit bevel 112 to the direction close to the axial limit bevel 112, the axial limit bevel 112 is inclined toward the inner side of the mounting hole 11. Such a setting can make the position, shape and size of the axial limit bevel 112 reasonably set. When the turbine shaft assembly 200 is assembled on the quality control inspection fixture 100, it is beneficial to set the axial limit bevel 112 at a position corresponding to the bevel of the neck 205, and make the axial limit bevel 112 reliably abut against the bevel of the neck 205 for limiting. In the process of rotating the turbine shaft assembly 200, it is beneficial for the axial swing detection part 3 to smoothly detect the runout value of the axial side swing, so as to detect whether the turbine shaft assembly 200 is qualified, and then screen out qualified turbine shaft assemblies 200 for subsequent processing, which is beneficial to meet the quality control requirements of the turbine shaft assembly 200 and reduce the scrap rate of the subsequent turbine shaft assembly 200 production line.

[0053] It should be noted that when the axial limit bevel 112 abuts against the bevel of the neck 205 for limiting, the junction of the large shaft 203 and the small shaft 204 is clearance-matched with the base 1 to reduce the risk of the base 1 wearing the junction of the large shaft 203 and the small shaft 204, thereby further reducing the risk of scrapping the turbine shaft assembly 200 and improving the detection safety of the turbine shaft assembly 200.

[0054] In some embodiments of the present invention, Figure 3 As shown, the axial limiting inclined surface 112 is annular and extends along the circumference of the mounting hole 11 .

[0055] Among them, the axial limiting bevel 112 is annular, and the axial limiting bevel 112 extends along the circumference of the mounting hole 11, so that the axial limiting bevel 112 has a certain area, which is beneficial for the axial limiting bevel 112 to reliably limit the turbine shaft assembly 200, and reduce the risk of excessive error in the runout value of the turbine shaft assembly 200 due to arbitrary shaking of the turbine shaft assembly 200, thereby reducing the risk of misjudgment of the quality of the turbine shaft assembly 200 and improving the accuracy of quality screening of the turbine shaft assembly 200.

[0056] In some embodiments of the present invention, Figure 1-Figure 3As shown, the base 1 may include: a base body 12 and a third mounting column 13, the first mounting column 2, the second mounting column 4 and the third mounting column 13 are all fixedly arranged on the upper surface of the base body 12, the third mounting column 13 is formed with a first sub-mounting hole 131, the base body 12 is formed with a second sub-mounting hole 121, the first sub-mounting hole 131 and the second sub-mounting hole 121 are opposite and adjacent, and the first sub-mounting hole 131 and the second sub-mounting hole 121 are configured as mounting holes 11. The axial limiting inclined surface 112 and the radial limiting surface 111 are both arranged inscribed in the first sub-mounting hole 131 and arranged on the side of the first sub-mounting hole 131 away from the second sub-mounting hole 121. Among them, the third mounting column 13 can be arranged between the first mounting column 2 and the second mounting column 4, and the first mounting column 2, the second mounting column 4 and the third mounting column 13 are all fixedly arranged on the upper surface of the base body 12. Such an arrangement can make the positions of the first mounting column 2, the second mounting column 4 and the third mounting column 13 reasonably arranged. By providing the first mounting column 2, the second mounting column 4 and the third mounting column 13 on the upper surface of the base 1, the turbine shaft assembly 200 is inserted into the first sub-mounting hole 131 from above, and the third mounting column 13 can support the turbine shaft assembly 200, which can reduce the risk of the turbine shaft assembly 200 falling from the quality control inspection fixture 100 during the inspection process, which is beneficial to improving the safety of the turbine shaft assembly 200 during the inspection process.

[0057] The first mounting column 2, the second mounting column 4 and the third mounting column 13 are all fixedly mounted on the upper surface of the base body 12, which is beneficial for the first mounting column 2, the second mounting column 4 and the third mounting column 13 to be arranged on the same side of the base 1, so that the turbine shaft assembly 200, the axial swing detection component 3 and the radial displacement detection component 5 can be arranged on the same side of the base 1, so that the axial swing detection component 3 and the radial displacement detection component 5 can simultaneously and smoothly detect the axial side swing runout value and the radial eccentricity runout value of the turbine shaft assembly 200, thereby improving the detection efficiency of the quality control inspection device 100.

[0058] The third mounting column 13 is formed with a first sub-mounting hole 131, and the base body 12 is formed with a second sub-mounting hole 121. The first sub-mounting hole 131 and the second sub-mounting hole 121 are arranged opposite to each other, and the first sub-mounting hole 131 and the second sub-mounting hole 121 are arranged adjacent to each other. The first sub-mounting hole 131 and the second sub-mounting hole 121 are jointly constructed as a mounting hole 11. When the turbine shaft assembly 200 is assembled on the quality control inspection device 100, the small shaft 204 is assembled on the second sub-mounting hole 121, and the large shaft 203 is assembled on the first sub-mounting hole 131. By setting the third mounting column 13, the assembly height of the turbine shaft assembly 200 can be matched with the height of the axial swing detection part 3 and the height of the radial displacement detection part 5, which is conducive to the axial swing detection part 3 and the radial displacement detection part 5 to smoothly detect the axial side swing runout value and the radial eccentricity runout value of the turbine shaft assembly 200 at the same time.

[0059] Furthermore, by adjusting the height of the first mounting column 2, the second mounting column 4 and the third mounting column 13, the height of the quality control inspection device 100 can be adjusted, so that the height is adjusted to a position that matches the height of the inspector, thereby reducing the difficulty for the inspector to turn the turbine shaft assembly 200. It can also reduce the difficulty for the inspector to read the axial side swing runout value and the radial eccentricity runout value, thereby reducing the inspection difficulty of the turbine shaft assembly 200, which is beneficial to improving the inspection and screening efficiency of the turbine shaft assembly 200.

[0060] In some embodiments of the present invention, Figure 1 As shown, the base 1, the first mounting column 2 and the second mounting column 4 are integrally formed.

[0061] Among them, the base 1, the first mounting column 2 and the second mounting column 4 are integrally formed, that is, the base 1, the first mounting column 2 and the second mounting column 4 are constructed as an integrally formed part, and the integrally formed part has good structural strength. By integrally forming the base 1, the first mounting column 2 and the second mounting column 4, the connection reliability of the base 1 and the first mounting column 2, the base 1 and the second mounting column 4 can be improved, and the probability of fracture at the connection between the base 1 and the first mounting column 2, the base 1 and the second mounting column 4 can be reduced, thereby improving the structural stability of the quality control inspection fixture device 100.

[0062] Furthermore, compared with the method of separately processing and then assembling the base 1, the first mounting column 2 and the second mounting column 4, the integrally formed base 1, the first mounting column 2 and the second mounting column 4 can reduce the processing molds and processing steps of the quality control inspection device 100, thereby reducing the production time and production cost of the quality control inspection device 100.

[0063] It should be noted that the traditional SWA (turbine shaft assembly 200) machining quality control full process solution is: EBW (electronic welding turbine shaft) initial welding - pull-out force detection (first inspection), penetration cutting detection (first inspection) - weld surface material metallographic inspection (first inspection) - ultrasonic non-destructive testing (100 inspections).

[0064] The new SWA turbine shaft assembly 200 machining quality control full process solution of the present application is: EBW initial welding - pull-out force detection (first inspection), penetration cutting detection (first inspection) - weld surface material metallographic inspection (first inspection) - detection of "axial sway and radial eccentricity" (new addition in 100 inspections) through the quality control inspection device 100 - ultrasonic non-destructive testing (100 inspections). By adding the detection steps of axial sway and radial eccentricity, the quality control of the turbine shaft assembly 200 is effectively improved.
