Description

Technical Field

[0001] The invention relates to the technical field of blade production equipment, and in particular to a blade surfacing wear-resistant layer defect detection tool and a detection method. Background Art

[0002] Low-pressure turbine blades are mostly in the form of a serrated crown structure. Adjacent blades need to cooperate with each other through the damping surface of the serrated crown, and the wear-resistant layer is welded on the damping surface of the serrated crown by argon arc welding to reduce excessive wear of the damping surface during engine operation. In the production process of turbine rotors, due to the complex structure of the turbine rotor blade crown, it is generally produced by precision casting without excess. During this molding process, there will be production defects such as slag inclusions, holes, cracks, surface defects, and casting defects inside the blade crown, which will cause defects in the wear-resistant layer of the blade crown. At present, in the defect detection of the wear-resistant layer of the blade crown, due to the complex blade body shape and different cross-sections along the blade length, it is not easy to perform fixed detection. Instead, the fluorescent penetrant is manually applied to the surface of the blade crown, and then the ultraviolet radiation is used to detect whether the wear-resistant layer of the turbine rotor blade crown is defective. It not only has a low degree of automation and low detection efficiency, but also the manual application will cause the problem of uneven application of the fluorescent penetrant, which affects the accuracy of the detection results.

DETAILED DESCRIPTION

[0035] The core of the present invention is to disclose a blade cladding wear-resistant layer defect detection tool to improve the defect detection efficiency and accuracy of the blade crown cladding wear-resistant layer.

[0036] Another object of the present invention is to provide a detection method suitable for the above-mentioned detection tooling.

[0037] In order to make the technical personnel in this field better understand the scheme of the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention recorded in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the invention recorded in the claims.

[0038] like Figure 1 As shown, the blade surfacing wear-resistant layer defect detection tool provided by the embodiment of the present invention includes a detection chamber 10 and a brushing part 20, wherein the detection chamber 10 is set with an opening at the top in the vertical direction, and the detection chamber 10 specifically includes a bottom plate to contact the placement plane, and when the detection chamber 10 is placed in a use state, the bottom plate is located at the bottom of the detection chamber 10 in the vertical direction. The detection chamber 10 can be a vertical plate arranged around the bottom plate to form an enclosure structure, or a plurality of columns can be arranged on the bottom plate to form an open cavity structure; in some embodiments of the present invention, in order to improve the closure of the detection chamber 10, a vertical plate structure is preferably arranged on the bottom plate to improve the convenience of the subsequent imaging process. The detection chamber 10 is at least set with an opening at the top in the vertical direction, and the brushing part 20 covers the top opening of the detection chamber 10 in the vertical direction, and preferably, in order to improve the convenience of the brushing part 20, the brushing part 20 is connected to the detection chamber 10 in a vertical direction with adjustable height. It should be noted that the brushing part 20 can be slidably disposed as a whole on the side wall structural component of the detection chamber 10, or it can be connected to the side wall or base of the detection chamber 10 through a retractable structure such as a push rod to achieve its height adjustment in the vertical direction.

[0039] Specifically, the brushing part 20 includes a penetrant container 210 and a brushing assembly 220, wherein the penetrant container 210 is used to contain a fluorescent penetrant, i.e., a substance used to apply to the crown area of ​​the blade to detect defects in the cladding wear-resistant layer. The vertical height of the penetrant container 210 is higher than that of the brushing assembly 220, and is connected to the brushing assembly 220, so that when the fluorescent penetrant needs to be added to the brushing assembly 220, the fluorescent penetrant can flow into the brushing assembly 220 by gravity; and the brushing assembly 220 is arranged toward the inside of the detection cavity 10, i.e., toward the bottom plate of the detection cavity 10. A clamping assembly 30 is also provided in the detection chamber 10, and the clamping assembly 30 includes at least a first driving part 310 and a first gear 320. The first driving part 310 and the first gear 320 are transmission connected to each other so as to drive the first gear 320 to rotate along its axial direction. The first gear 320 is used to clamp and fix the blade. It should be noted that since the shape of the crown area on the blade is more complicated, the first gear 320 and the brushing assembly 220 are spaced apart so that the first gear 320 can be on the relatively flat and regular area on the blade, such as the root area of ​​the blade, to maintain its stable connection effect, and after fixing the blade, the crown area of ​​the blade is located directly below the brushing assembly 220. On the basis of the above structure, after the blade is fixed on the first gear 320, the brush assembly 220 can be made to contact the blade crown area by adjusting the height of the brushing part 20, and under the driving action of the first driving part 310 and the filling action of the penetrant container 210 on the brush assembly 220, the fluorescent penetrant can be applied to the blade crown area in a rotating state through the brush assembly 220. It should be noted that it is preferred that the brush assembly 220 contacts and is pressed onto the blade crown area with an appropriate force, so that when there is a concave defect on the blade crown area, the brush assembly 220 can effectively apply the fluorescent penetrant to the concave defect position under the action of pressure.

[0040] On the basis of the above-mentioned embodiment, the blade cladding wear-resistant layer defect detection tool further includes a shooting component 40 and an imaging component 50, wherein the imaging component 50 may be a visual sensor and a camera, etc., which are components that can capture and transmit images, and the visualization component is used to generate ultraviolet radiation. It should be noted that in the detection tool provided by the embodiment of the present invention, the fluorescent penetrant contained in the penetrant container 210 is a water-washable fluorescent penetrant. At the same time, the shooting area of ​​the shooting component 40 is set toward the blade crown area to cover the blade crown area.

[0041] Furthermore, if Figure 2As shown, in some embodiments of the present invention, the first driving part 310 is a motor with a mature structure and easy to assemble and use. The motor is fixedly arranged on the bottom plate of the detection chamber 10, and the power output shaft of the motor is sleeved with a second gear 330 to drive the second gear 330 to rotate, and the outer periphery of the second gear 330 is meshed with a third gear 340 and a fourth gear 350. It should be noted that the central axis areas of the third gear 340 and the fourth gear 350 are fixedly arranged on the bottom plate of the detection chamber 10 through an L-shaped support rod 360, so that the third gear 340 and the fourth gear 350 are 0 can be stably supported in the meshing area with the second gear 330, and at the same time, the third gear 340 and the fourth gear 350 are both meshed with the first gear 320, that is, in the above structure, the first driving part 310 realizes the transmission of the first gear 320 through the second gear 330, the third gear 340 and the fourth gear 350, which can not only improve the rotation stability of the first gear 320 through the meshing action of the multi-stage gears, but also the third gear 340 and the fourth gear 350 can support the first gear 320, thereby reducing the risk of the first gear 320 being deflected when fixing the blade.

[0042] On the basis of the above embodiments, Figure 2 , Figure 3 and Figure 6As shown, the first gear 320 is preferably a notched gear for fixed assembly of the blade 70. Specifically, the first gear 320 is provided with a placement groove 3210 in its notched area, which extends inward from the outer wall of the first gear 320. The placement groove 3210 is an arc-shaped structure for the end of the blade 70 or other regular arc-shaped areas to be inserted. At the same time, combined with the structure of the placement slot 3210, a spring slot 3220 and a sliding block 3230 are also provided on the first gear 320. The spring slot 3220 is arranged close to the placement slot 3210, and the sliding block 3230 is slidably arranged in the spring slot 3220, and the sliding block 3230 is connected to the bottom of the spring slot 3220 through a spring. Specifically, the spring can drive the sliding block 3230 to slide along the spring slot 3220 in the absence of external force, and since the spring slot 3220 is arranged close to the placement slot 3210, the sliding block 3230 can be driven by the spring to close the gap area on the outer wall of the first gear 320; at the same time, when the operator drives the sliding block 3230 into the spring slot 3220, the spring is compressed, and the sliding block 3230 can be at least partially embedded in the spring slot 3220 to open the gap area of ​​the first gear 320. In the above structure, the operator can first push the sliding block 3230 into the spring groove 3220 and continue to apply pressure to the sliding block 3230 to open the opening area of ​​the placement groove 3210 on the first gear 320 to place the blade 70 into the placement groove 3210; after completing the placement of the blade 70, release the sliding block 3230, and the sliding block 3230 pops up under the action of the spring and closes the notch area of ​​the first gear 320 to complete the fixation and limitation of the blade 70.

[0043] It should be further explained that, since the first gear 320 is a notched gear design structure and some areas on its outer wall have no gear teeth, the third gear 340 and the fourth gear 350 are provided to cooperate in driving the first gear 320. When the notched area on the first gear 320 rotates to the meshing position of the first gear 320 and the third gear 340, the first gear 320 can achieve transmission under the meshing action of the fourth gear 350, and vice versa. The coordinated transmission of the two gears can achieve a continuous and stable driving effect of the first gear 320 with a notch.

[0044] As for the brush assembly 220 for coating the blade crown area, Figure 4As shown, in some embodiments of the present invention, the brush assembly 220 mainly includes a solution cavity 2210, a connecting plate 2220 and bristles 2230. Specifically, a hole is opened at the bottom of the penetrant container 210 to allow the fluorescent penetrant to flow out from the bottom of the penetrant container 210, and the top of the solution cavity 2210 is connected to the bottom opening of the penetrant container 210 through the connecting plate 2220. The connecting plate 2220 constitutes a transition area for temporary storage of the fluorescent penetrant. On the basis of achieving upper and lower communication through the connecting plate 2220, the solution cavity 2210 is respectively provided with drip holes 22110 on both side walls in the vertical direction. It should be noted that the solution cavity 2210 and the penetrant container 210 are connected through a hole structure, which is difficult to align, so a transition needs to be achieved through a connecting plate 2220. The output and reception of the fluorescent penetrant through the hole structure can reduce the impact of the fluorescent penetrant delivery process, allowing the fluorescent penetrant to enter the solution cavity 2210 more gently and have a more sufficient impregnation effect.

[0045] On this basis, the bristles 2230 are fixedly connected to the bottom of the solution cavity 2210. The bristles 2230 are a structure used to contact the crown area of ​​the blade. The bristles 2230 receive the fluorescent penetrant through the drip hole 22110 at the bottom of the solution cavity 2210, and under the dripping action, the bristles 2230 in each area fully absorb the fluorescent penetrant, and can continuously output the fluorescent penetrant during the rotation of the crown area to achieve uniform coating on the crown area.

[0046] In order to further optimize the above technical solution, in some embodiments of the present invention, the bristles 2230 are in an inverted conical structure, and the bottom area of ​​the conical structure is fixed to the bottom of the solution cavity 2210 for receiving the fluorescent penetrant from the drip hole 22110; and the tip area of ​​the conical structure is arranged toward the bottom plate of the detection cavity 10 for coating the leaf crown area. It should be noted that the bristles 2230 form a closed cavity 22310 in the midline area of ​​its conical structure, and the drip hole 22110 at the bottom of the solution cavity 2210 is connected to the closed cavity 22310. The fluorescent penetrant flowing out from the drip hole 22110 at the bottom of the solution cavity 2210 can produce a certain accumulation effect in the cavity structure. At the same time, the area of ​​the bristles 2230 with denser tips can also fully receive the fluorescent penetrant, making the coating of the fluorescent penetrant on the leaf crown area more uniform. At the same time, the fluorescent penetrant can only contact with the inner side of the conical bristles 2230, avoiding the problem of fluorescent penetrant sagging on the outside of the bristles 2230.

[0047] In order to improve the versatility of the inspection tooling, Figure 1 and Figure 5As shown, in some embodiments of the present invention, multiple groups of brushing assemblies 220 are arranged at intervals to be able to apply fluorescent penetrant to the crown area of ​​leaves of different sizes, and one or more of the multiple groups of brushing assemblies 220 work together to meet the detection requirements. On this basis, a conductive plate 230 is also slidably arranged at the bottom of the penetrant container 210, and the conductive plate 230 is arranged between the penetrant container 210 and the brushing assembly 220 in the vertical direction to isolate the penetrant container 210 from the brushing assembly 220. Meanwhile, a plurality of conducting holes 2310 are provided on the conducting plate 230. The conducting holes 2310 are through-hole structures, which penetrate the upper and lower walls of the conducting plate 230 in the vertical direction. When the conducting plate 230 is slidably arranged at the bottom of the osmotic agent container 210, only when a single conducting hole 2310 is aligned with a group of drip holes 22110 of the solution cavity 2210 and the bottom opening of the osmotic agent container 210, that is, when the bottom opening of the osmotic agent container 210, the conducting hole 2310 and the drip hole 22110 are located on the same vertical line, the corresponding solution cavity 2210 is connected to the osmotic agent container 210. The setting of the conduction plate 230 satisfies the connectivity function of the osmotic agent container 210 with different solution cavities 2210, and when multiple brush assemblies 220 are set, the corresponding brush assembly 220 can be selected to start. Similarly, digital or letter labels can be set on the conduction plate 230 to indicate the position where it can connect to the corresponding solution cavity 2210.

[0048] Furthermore, in some embodiments of the present invention, the detection tooling also includes an electric telescopic rod 60, which is fixedly arranged on the side wall, column or bottom floor structure of the detection chamber 10, and the action end of the electric telescopic rod 60 is arranged against the brushing part 20, and the electric telescopic rod 60 is connected to the detection chamber 10 in a height-adjustable manner in the vertical direction through the area of ​​the action end. At the same time, it should be noted that it is preferred that a plurality of electric telescopic rods 60 are arranged and evenly abut the brushing part 20, and evenly abutting here means that each telescopic rod bears the same force. For example, when the brushing part 20 is a rectangular structure, four electric telescopic rods 60 can be arranged and respectively arranged at the four corners of the brushing part 20.

[0049] Furthermore, in some embodiments of the present invention, the photographing component 40 is an industrial camera with high-speed photographing capability and stable and reliable performance; the imaging component 50 is a mercury quartz lamp for generating ultraviolet radiation.

[0050] In addition, it should be noted that, in some embodiments of the present invention, the penetrant container 210 is a rectangular cavity structure, so as to have a regular structure and be stably supported, and the penetrant container 210 is provided with an opening at its top for filling with fluorescent penetrant.

[0051] Furthermore, an embodiment of the present invention also provides a method for detecting defects in a blade surfacing wear-resistant layer. The method uses the blade surfacing wear-resistant layer defect detection tool provided in any of the above embodiments to perform defect detection on the blade surfacing wear-resistant layer. Specifically, the method includes at least the following steps:

[0052] S01: Assembling the blade: fix the blade to the first gear on the clamping assembly so that the blade crown is located directly below the brushing assembly, and adjust the height of the brushing part so that the brushing assembly in the brushing part contacts the blade crown.

[0053] It should be noted that when the first gear is a notched gear, the blade root can be fixed by an arc-shaped inner groove structure so that the blade crown area is located directly below the painting assembly.

[0054] S02: driving the blades: opening the first driving part in the clamping assembly to drive the first gear to rotate, and the first gear drives the blades and the blade crown to rotate synchronously.

[0055] S03: Filling the penetrant: connecting the penetrant container containing the fluorescent penetrant and the brush assembly, so that the fluorescent penetrant reaches the leaf crown through the contact between the brush assembly and the leaf crown, and the fluorescent penetrant is evenly applied to the surface of the leaf crown through the rotation of the leaf crown.

[0056] It should be noted that in step S02 and step S03, after the crown area of ​​the blade contacts the coating assembly, the crown area is rotated first, and then the fluorescent penetrant in the coating assembly is filled, so as to avoid a large amount of fluorescent penetrant dripping and waste when filling the fluorescent penetrant first, and the problem of uneven coating in the crown area.

[0057] S04: Imaging and shooting: After the fluorescent penetrant is applied on the leaf crown surface, disconnect the penetrant container and the brush assembly, and raise the brush part to separate the brush assembly from the leaf crown. The first drive part drives the first gear to rotate slowly, turn off all external lights, turn on the imaging component, and shoot the leaf crown surface through the shooting component. The defects on the leaf crown surface appear as blue-green spots or stripes under the action of ultraviolet radiation emitted by the imaging component.
