[0002] In new material-related services, online testing devices for the scratch resistance of enameled wire utilize mechanical stress to test scratch resistance. This is mainly achieved by designing specific mechanical structures to make a scraping tool contact and scrape the enameled wire. The scraping components apply mechanical stress to the surface of the coating at a preset frequency, simulating the friction and scraping action on the coating in actual production.

[0003] In publicly available literature, patent publication number CN216621979U discloses an online testing device for the scratch resistance of semi-open enameled wire. This technology connects one end of a detection component to a scratching component, while the other end of the detection component abuts against a damaged area of ​​the enameled wire's coating. This invention enables online testing of the scratch resistance of enameled wire, accelerates the determination of sample processing, effectively reduces waste wire rate, and lowers production costs. However, this technology has the following drawbacks.

[0004] Current testing methods for the scratch resistance of enameled wire have limitations. During testing, the enameled wire is in a single horizontal state, and friction testing is conducted by scraping the wire with a scraper.

[0015] The technical effects and advantages of the present invention.

[0016] 1. This invention employs a multi-directional cross test piece and a linkage scraper. When the moving block moves up and down reciprocally, the pressure groove frame drives the pressure shaft to drive the scraping inclined plate to stably scrape the cross-side of the enameled wire along the protruding post.

The inclined groove frame drives the inclined shaft to make the side inclined scraper stably scrape the cross-offset side along the inclined protruding rod. It stably applies pressure and scrapes the cross-section of the enameled wire in different directions, simulating the test under the actual winding contact state. This not only has a wider range of applicable test coverage, but also greatly improves the test efficiency.

[0017] 2. This invention employs a linkage scraper, which drives the linkage shaft and rotating bar to rotate clockwise and then counterclockwise through the meshing of a rack and gear. This causes the arc-shaped block to slide along the guide rail. The grooved bar is connected to the sleeve block through the positioning shaft, and under the elastic floating support of the spring sheet, the scraping bar can fit against the curved corner of the enameled wire for scraping. This achieves stable and close-fitting scraping test at the curved corner of the enameled wire, further improving the authenticity and coverage of the test. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1: like Figure 1 The online testing device for the scratch resistance of enameled wire shown includes a winding base 1, on the outer wall of which is provided a cross-wound enameled wire 2; a moving block 3, which slides on one side of the winding base 1, and a multi-directional cross test piece is installed on the outer wall of the moving block 3 near its top, on which a scratching inclined plate 4, a middle scraper 5, and a side-sloping scraper 6 are installed; a linkage scraper is installed on one side of the moving block 3, and a scraping bar 7 is provided on the linkage scraper; and a power unit is installed inside the winding base 1.

[0031] The operating principle of this embodiment is as follows: The winding base 1 is fixed to the test table by inserting bolts into the holes at the bottom of the mounting bolts, providing stable support. The enameled wire 2 is then wound around the outer wall of the winding base 1 in a cross-positioning manner for installation. A power component drives a moving block 3 to move up and down reciprocally. The moving block 3 drives a multi-directional cross-testing component, which in turn drives the scraping ramp 4, side ramp scraper 6, and intermediate scraper 5 to simultaneously scrape the cross ramp side, cross offset side, and cross top of the enameled wire 2. Simultaneously, the moving block 3 drives a linkage scraper, which in turn drives a scraping bend 7 to scrape the curved corner of the enameled wire 2. This simulates the cross-contact state of the enameled wire 2 in actual use, applying stable guiding pressure simultaneously to the offset side, ramp side, cross top, and curved corner of the cross-section. This not only broadens the testing coverage but also significantly improves testing efficiency.

[0032] Example 2: In this embodiment, as Figure 2 - Figure 3As shown, the multi-directional cross test piece includes: a groove frame 8, fixedly connected to one side of the outer wall of the movable block 3 near its top; a pressing shaft 9 is slidably connected to the inner wall of the groove frame 8; the groove frame 8 is inclined; the pressing shaft 9 is fixedly connected to the scraping inclined plate 4; a connecting strip 10 is installed on the upper inclined surface of the scraping inclined plate 4; both the scraping inclined plate 4 and the inter-scraper 5 are fixedly connected to the connecting strip 10; the scraping inclined plate 4 is in contact with the enameled wire 2; a protruding post 11 penetrates the interior of the scraping inclined plate 4; the bottom end of the protruding post 11 is connected to the winding seat 1. The scraping plate 4 is fixedly connected to the moving block 3, with a protruding post 11 guiding the sliding of the scraping plate 4. A sloping groove frame 12 is fixedly connected to the other side of the outer wall of the moving block 3, near its top. An angle is formed between the sloping groove frame 12 and the moving block 3, and the pressing groove frame 8 is perpendicular to the moving block 3. A sloping shaft 13 slides on the inner wall of the sloping groove frame 12 and is fixedly connected to the side sloping scraper 6. A sloping protruding rod 14 is installed on the inner wall of the side sloping scraper 6 and is fixedly connected to the winding seat 1. The side sloping scraper 6 contacts the enameled wire 2. The upper inclined surface of the scraping plate 4 is parallel to the lower inclined surface of the intermediate scraper 5, and a gap is provided between the scraping plate 4 and the intermediate scraper 5. The side sloping scraper 6 is perpendicular to the sloping shaft 13, and the sloping protruding rod 14 guides the sliding of the side sloping scraper 6.

[0033] The operating principle of this embodiment is as follows: when the moving block 3 moves up and down reciprocally, the moving block 3 will drive the pressing frame 8 to move up and down reciprocally. The pressing frame 8 will drive the pressing shaft 9 to start moving up and down reciprocally. At the same time, the pressing shaft 9 will slide along the inner wall of the pressing frame 8. In this way, the pressing shaft 9 will drive the scraping inclined plate 4 to move up and down reciprocally. The scraping inclined plate 4 will move up and down reciprocally and stably along the outer wall of the protrusion 11. The scraping inclined plate 4 will guide the cross-shaped oblique part of the enameled wire 2 to move up and down reciprocally and stably for scraping test. At the same time, the scraping inclined plate 4 will drive the connecting strip 10 to move up and down reciprocally. The connecting strip 10 will drive the intermediate scraper 5 to move up and down reciprocally. The intermediate scraper 5 will start moving up and down reciprocally and scraping test on the top of the cross-shaped part of the enameled wire 2.

[0034] Simultaneously, the moving block 3 drives the inclined groove frame 12, which is offset and tilted, to move up and down reciprocally. The inclined groove frame 12 drives the inclined shaft 13 to move up and down reciprocally. The inclined shaft 13 drives the side inclined scraper 6 to move up and down reciprocally. The side inclined scraper 6 moves up and down reciprocally along the outer wall of the inclined convex rod 14. The side inclined scraper 6 can then move up and down reciprocally with the cross-offset side of the enameled wire 2. In this way, the scraping inclined plate 4, the side inclined scraper 6, and the intervening scraper 5 simultaneously perform a stable scraping test on the cross-offset side, the cross-offset side, and the cross top of the enameled wire 2. If the scraped part is not damaged by paint peeling, it is qualified; if it is damaged by paint peeling, it is unqualified. The test data is transmitted remotely to the back-end management computer online through the wireless controller 29. In this way, the testing operation of the enameled wire 2 can be realized in the new material related services. Not only is the testing coverage wider, but the testing efficiency is also greatly improved.

[0035] Example 3: In this embodiment, as Figure 2 - Figure 5 As shown, the linkage scraper includes: a rack 15, fixedly connected to one side of the moving block 3, with a gear 16 meshing and drivingly connected to one side of the inner wall of the rack 15, and a coaxial linkage shaft 17 fixed to the inner wall of the gear 16, the linkage shaft 17 being rotatably connected to the winding seat 1; a rotating bar 18, one end of which is fixed to one side of the outer wall of the linkage shaft 17, and an arc-shaped block 19 fixed to the other end of the rotating bar 18; and a guide rail 20, installed on the outer wall of the arc-shaped block 19, the guide rail 20 being fixed to the winding seat 1. A guide rail 20 is used to guide the sliding of the arc-shaped block 19. A groove 21 is fixedly connected to one end of the arc-shaped block 19. A positioning shaft 22 is fixedly installed on the inner wall of the groove 21, and a sleeve 23 is provided on the outer wall of the positioning shaft 22. The sleeve 23 is fixedly connected to the scraper bar 7, and the positioning shaft 22 is used to position the sleeve 23 to rotate. A spring piece 24 is provided on one side of the scraper bar 7. Both the groove 21 and the scraper bar 7 are fixedly connected to the spring piece 24, and the spring piece 24 is used to provide elastic force to the scraper bar 7. There is a gap between the groove 21 and the scraper bar 7, and the groove 21 is slidably connected to the guide rail 20. The upper surface of the scraper bar 7 is at the same level as the upper surface of the groove 21.

[0036] The operating principle of this embodiment is as follows: when the moving block 3 moves up and down reciprocally, the moving block 3 drives the rack 15 to move up and down reciprocally. The rack 15 drives the gear 16 to rotate clockwise and then counterclockwise. The gear 16 drives the linkage shaft 17 to rotate clockwise and then counterclockwise. The linkage shaft 17 rotates clockwise and then counterclockwise on the winding seat 1. The linkage shaft 17 drives the rotating bar 18 to rotate clockwise and then counterclockwise. The rotating bar 18 drives the arc block 19 to rotate clockwise and then counterclockwise. The arc block 19 rotates clockwise and then counterclockwise along the inside of the guide rail 20.

[0037] In this way, the guide rail 20 can guide the arc block 19 to slide back and forth, and the arc block 19 drives the groove 21 to rotate clockwise and then counterclockwise, ensuring that the groove 21 can stably achieve clockwise and then counterclockwise rotation. The groove 21 drives the positioning shaft 22 to rotate clockwise and then counterclockwise, and the positioning shaft 22 drives the sleeve block 23 to rotate clockwise and then counterclockwise. At the same time, the groove 21 drives the spring piece 24 to rotate clockwise and then counterclockwise, and the spring piece 24 and the sleeve block 23 drive the scraper bar 7 to rotate clockwise and then counterclockwise. In this way, the scraper bar 7 stabilizes the curved corner of the enameled wire 2 according to the guide position of the guide rail 20. During the scratch test, when the scraping bar 7 contacts the curved corner of the enameled wire 2, the scraping bar 7 drives the sleeve block 23 to rotate laterally. The sleeve block 23 rotates laterally along the outer wall of the positioning shaft 22. At the same time, the spring piece 24 provides a lateral floating elastic force to the scraping bar 7. In this way, the scraping bar 7 can fit against the curved corner of the enameled wire 2 for the scratch test. If the scratched area is not damaged by paint peeling, it is qualified; if it is damaged by paint peeling, it is unqualified. The test data is transmitted remotely to the back-end management computer online through the wireless controller 29. This not only expands the applicable testing coverage but also greatly improves testing efficiency.

[0038] Example 4: In this embodiment, as Figure 6 - Figure 7 As shown, the power components include: a socket block 25, which slides on the inner wall of the winding base 1, and is fixedly connected to the moving block 3. The inner wall of the socket block 25 is provided with a threaded screw 26, and a torque sensor 28 is installed at the top of the screw 26. The top of the torque sensor 28 is fixedly connected to the winding base 1, and the torque sensor 28 is used to sense the torque of the screw 26. A geared motor 27 is installed at the bottom of the screw 26, and the geared motor 27 is used to drive the screw 26 to rotate. The outer wall of the geared motor 27 is fixedly connected to the winding base 1. A wireless controller 29 is provided below the moving block 3, and the wireless controller 29 is fixedly connected to the winding base 1. The geared motor 27 and the torque sensor 28 are both electrically connected to the wireless controller 29.

[0039] The operating principle of this embodiment is as follows: the screw 26 is driven to rotate forward by the geared motor 27, and the screw 26 drives the sleeve block 25 to engage in transmission. Under the action of the thread transmission force, the sleeve block 25 begins to move upward along the inner wall of the winding seat 1. At the same time, the sensing end of the torque force sensor 28 senses the torque force of the screw 26 to ensure that the screw 26 moves upward stably according to the specified torque force during transmission. Meanwhile, the sleeve block 25 drives the moving block 3 to move upward. After the moving block 3 moves upward, the screw 26 is driven to rotate in reverse by the geared motor 27. The screw 26 drives the sleeve block 25 to move downward under the action of the thread transmission force. In this way, the sleeve block 25 drives the moving block 3 to move downward. At the same time, the sensing end of the torque force sensor 28 senses the torque force of the screw 26 to ensure that the moving block 3 moves up and down stably.

[0040] Example 5: In this embodiment, as Figure 8 - Figure 9 As shown, each end of the enameled wire 2 is fitted with a mounting sleeve 30, and each mounting sleeve 30 has a bolt 31 threadedly connected to its outer wall. The outer wall of the mounting sleeve 30 is provided with a support bar 32, and one side of the support bar 32 is provided with a reinforcing bar 33. Both the support bar 32 and the reinforcing bar 33 are fixedly connected to the winding seat 1. The mounting sleeve 30 is fixedly connected to the support bar 32, and the other mounting sleeve 30 is fixedly connected to the reinforcing bar 33.

[0041] The operating principle of this embodiment is as follows: When installing the enameled wire 2, the enameled wire 2 is cross-positioned and wound around the outer wall of the winding seat 1. The cross-angled oblique side of the enameled wire 2 contacts the scraping oblique plate 4, and at the same time, the cross-offset side of the enameled wire 2 contacts the side oblique scraper 6. Meanwhile, one end of the enameled wire 2 is inserted into the installation sleeve 30, and the other end of the enameled wire 2 is inserted into another installation sleeve 30 to achieve straightening. By rotating the two bolts 31, the bolts 31 and the installation sleeve 30 are threadedly engaged and locked. In this way, the enameled wire 2 is cross-positioned and wound, simulating the scraping performance test of the actual enameled wire 2 in the contact state of winding.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
