Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-6 As shown, the present invention is a device for detecting the quality of blades.

[0021] Example 1 Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 In this invention, a technical solution is provided: a mounting platform 1, a detection frame 2 is fixedly mounted on the upper end of the mounting platform 1, an infrared microscope 3 is provided at the front end of the detection frame 2, a connecting frame plate 4 is provided at the lower end of the detection frame 2, a second hydraulic telescopic rod 5 is provided on the right side of the detection frame 2, and a mounting bracket 6 is provided on the upper left side of the mounting platform 1. The mounting platform 1 is equipped with a reciprocating screw 103 that can move the movable base 104 laterally left and right, and a circular blade body 108 is provided above the movable base 104. The mounting bracket 6 has a take-up roller 602 connected to the paper roll 603 on its front side, and a drawing pen 608 connected to the movable support plate 605 is provided on the front surface of the paper roll 603.

[0022] Furthermore, the reciprocating lead screw 103 is threadedly connected to the movable base block 104, and both ends of the movable base block 104 are provided with side baffles 105 that slide laterally within the mounting platform 1. A second servo motor 106 is also provided on the inner side of the movable base block 104. A movable mounting seat 107 is provided on the upper end of the second servo motor 106 for centering the circular blade body 108. A nut 109 is threadedly connected to the upper part of the movable mounting seat 107.

[0023] Furthermore, the take-up roller 602 is wound and connected to the paper roll 603, and the paper roll 603 is arranged symmetrically about the center line of the mounting bracket 6. The mounting bracket 6 is fixedly connected to the third mounting box 604, and the lower end of the third mounting box 604 is mounted on the upper end of the mounting platform 1.

[0024] Furthermore, the inner side of the third mounting box 604 is also provided with a second damping spring 606 connected to the movable support plate 605, and the outer end of the movable support plate 605 is movably connected with a roller 607. The rear inner side of the third mounting box 604 is provided with a clearance groove.

[0025] Furthermore, the movable support plate 605 forms an elastic telescopic movement within the third mounting box 604 via the second damping spring 606, and the movable support plate 605 forms a snap-fit ​​sliding structure on the third mounting box 604 via the clearance groove. The drawing pen 608, which is fixedly installed at the rear end of the movable support plate 605, is in an abutting fit with the front surface of the roll paper 603.

[0026] Specifically, firstly, the circular blade body 108 requiring quality inspection is fitted onto the movable mounting base 107, and a nut 109 is used to thread it onto the movable mounting base 107, so that the circular blade body 108 can be securely installed on the movable mounting base 107. During quality inspection, the first servo motor 102 is turned on to rotate the reciprocating screw 103, causing the movable base block 104, which is threadedly connected to the reciprocating screw 103, to slide laterally within the mounting platform 1. Since side baffles 1 are fixedly installed at both ends of the movable base block 104... 05. It can shield the upper surface of the front groove of the mounting platform 1 to prevent the circular blade body 108 from cracking or other impurities from entering during subsequent quality inspection, which could cause the reciprocating screw 103 to jam and become blocked. The movable base block 104 is equipped with a second servo motor 106, which can generate a rapid rotational force on the circular blade body 108 when detecting the cutting status of different materials. The fixed crossbar 101 installed at the upper end of the mounting platform 1 can provide stable rear support for the circular blade body 108.

[0027] Next, when the reciprocating screw 103 moves the movable base block 104, it can drive the circular blade body 108 from the left end to the right end. When passing the mounting bracket 6, since the roller 607 is movably connected to the upper end of the movable support plate 605, the inner end surface of the roller 607 will abut against the upper and lower surfaces of the circular blade body 108. When the circular blade body 108 passes, the movable support plate 605 will move up and down in the third mounting box 604 under the elastic action of the second damping spring 606. At this time, if the upper and lower surfaces of the circular blade body 108 are not flat enough, the greater the movement of the movable support plate 605, the greater the surface roughness of the circular blade body 108. The smaller or no movement of the movable support plate 605, the smaller the surface roughness of the circular blade body 108. Within a reasonable manufacturing error, it can meet the standard.

[0028] The movable support plate 605 has a fixed engraving pen 608 at its rear end. When the movable support plate 605 moves up and down, the rear end of the engraving pen 608 will come into contact with the front end surface of the roll paper 603, so that the engraving pen 608 can engrave a circuit diagram on the roll paper 603. This allows for a direct view of the surface flatness of the circular blade body 108. The roll paper 603 is wound and connected to the take-up roller 602. When the next piece of the circular blade body 108 is inspected, the fourth servo motor 601 can be turned on to rotate the take-up roller 602, causing the roll paper 603 wound and connected to the outside of the take-up roller 602 to be repositioned, so that the inspection effect is more intuitive and clear.

[0029] The front of the detection frame 2 is equipped with an infrared microscope 3, which can be used for detection by microscope or infrared light. The principle is that the infrared microscope 3 illuminates the sample with an infrared light source. Different chemical groups will absorb infrared light of specific wavelengths and form characteristic absorption spectra. The system focuses the infrared light on a small area of ​​the sample to be tested. The monitor measures the reflected or transmitted infrared spectral signal. By analyzing the characteristic peaks of the spectrum, the chemical composition, molecular structure and functional group distribution of the area can be determined. Its main testing items include: chemical composition analysis, contaminant detection, and material defect analysis. Chemical composition analysis: Identification of blade material composition, analyzing the chemical composition of the blade substrate material to confirm whether it meets the standard requirements; Coating composition detection: Detecting the chemical composition of the coating material to verify the coating quality; Heat treatment status analysis: Judging whether the heat treatment process is qualified by metallographic characteristics such as carbide distribution and retained austenite; Contaminant detection: Surface contaminant analysis, detecting contaminants such as oil, fingerprints, and fibers adhering to the blade surface; Manufacturing process contamination: Identifying impurities and foreign objects introduced during processing; Corrosion product analysis: Analyzing the composition of oxidation and corrosion products on the blade surface; Material defect analysis: Interface bonding state, detecting whether there are defects at the interface between the coating and the substrate; Microcrack analysis: Identifying microcrack areas through compositional changes; Oxide layer analysis: Detecting the degree of oxidation on the blade surface.

[0030] Example 2 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 In this invention, a technical solution is provided: a first movable clamping plate 407 and a second movable clamping plate 409 are respectively provided on the upper and lower sides of the inside of the connecting frame plate 4 for clamping the cutting substrate 4010.

[0031] Furthermore, a third servo motor 403 is installed on the inner side of the connecting frame plate 4. Both ends of the third servo motor 403 are movably connected to the drive gear 404. Below the drive gear 404, a driven gear 406 connected to the connecting frame plate 4 is provided. Both the driving gear 404 and the driven gear 406 have a linkage shaft fixedly installed on their inner ends for winding and connecting with the belt 405.

[0032] Furthermore, the upper end of the drive gear 404 is meshed with a gear roller 408, and the gear roller 408 is meshed with the second movable clamping plate 409. Driven gear 406 is meshed with first movable clamping plate 407; The first movable clamping plate 407 and the second movable clamping plate 409 both form a snap-fit ​​sliding structure within the connecting frame plate 4.

[0033] Furthermore, a fixing pressure plate 402 is fixedly installed on the upper and lower sides of the front end of the connecting frame plate 4 to press the clamped cutting substrate 4010 against it, so that the middle contact part between the cutting substrate 4010 and the connecting frame plate 4 forms a hollow state.

[0034] Specifically, in embodiment one, after the circular blade body 108 passes the flatness test, it will continue to move to the right under the action of the movable base block 104. When it reaches the middle position of the mounting platform 1, cutting substrates 4010 of different materials are sequentially replaced and installed on the front side of the connecting frame plate 4. At this time, the third servo motor 403 is turned on to rotate the drive gear 404. Since the inner ends of both the drive gear 404 and the driven gear 406 are equipped with linkage shafts, when the drive gear 404 rotates, it can drive the driven gear 406 to rotate synchronously and in the same direction through the belt 405 that is wound and connected to both the drive gear 404 and the driven gear 406. At the same time, The driven gear 406 is meshed with a gear roller 408 at its upper end, which can cause the gear roller 408 to rotate in the opposite direction to the driving gear 404. Thus, the rotation direction of the driven gear 406 is opposite to that of the gear roller 408. Through the meshing connection between the driven gear 406 and the first movable clamping plate 407, and the meshing connection between the gear roller 408 and the second movable clamping plate 409, the first movable clamping plate 407 and the second movable clamping plate 409 can be driven to move in the same direction when the driven gear 406 and the gear roller 408 rotate, so as to use the first movable clamping plate 407 and the second movable clamping plate 409 to position and clamp the cutting substrate 4010.

[0035] Fixed pressure plates 402 are fixedly installed on both the upper and lower sides of the front end of the connecting frame plate 4. When the cutting substrate 4010 is fixedly installed in front of the connecting frame plate 4, the middle part of the connection between the cutting substrate 4010 and the connecting frame plate 4 is hollowed out by the pressure of the fixed pressure plates 402. This makes it easier for the circular blade body 108 to cut the cutting substrate 4010. By opening the first hydraulic telescopic rod 401 to drive the connecting frame plate 4 to move back and forth as a whole, the contact area between the circular blade body 108 and the cutting substrate 4010 can be increased, so that the cutting effect can be viewed more intuitively.

[0036] Example 3 This embodiment is derived based on Embodiment 1 and Embodiment 2. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 5 In this invention, a technical solution is provided: a second mounting box 504 is provided below the second hydraulic telescopic rod 5, and a compression rod 505 is provided on the inner side of the second mounting box 504 and is fitted to the pressure detector 503.

[0037] Furthermore, a first mounting box 502 connected to the mounting base plate 501 is fixedly mounted on the upper end of the second mounting box 504, and a pressure detector 503 is fixedly mounted on the inner side of the first mounting box 502. A first damping spring 506 is provided on the outer side of the compression rod 505.

[0038] Furthermore, the compression rod 505 is elastically telescopic within the second mounting box 504 via the first damping spring 506, and the upper surface of the compression rod 505 is fitted against the lower surface of the pressure detector 503. The extrusion rods 505 are evenly distributed below the mounting base plate 501.

[0039] Specifically, in conjunction with Embodiments 1 and 2, after the circular blade body 108 is inspected using the mounting bracket 6, connecting frame plate 4, and infrared microscope 3, the movable base block 104 is moved again, causing the circular blade body 108 to move to the right end. At this time, the second hydraulic telescopic rod 5 is opened to lower the mounting base plate 501, so that the lowest end of the extrusion rod 505 contacts the upper surface of the rear end of the circular blade body 108. Through the continuous descent of the second hydraulic telescopic rod 5, the extrusion rod 505 can elastically extend and retract within the second mounting box 504 via the first damping spring 506. The upper end of the extrusion rod 505 is in contact with the lower surface of the pressure detector 503 installed inside the first mounting box 502. At this time, the pressure applied by the second hydraulic telescopic rod 5 can be recorded through the first mounting box 502 until the extrusion rod 505 bends or breaks the circular blade body 108, thereby detecting the specific compressive strength of the circular blade body 108.

[0040] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
