[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0048] It should be noted that when an element is referred to as "mounted on", "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0049] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0050] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0051] As Figures 1 to 8 shown, this application provides a wear resistance test method for a film-coated product, including the following steps:

[0052] Step S1: First fixation, place the tubular film-coated product 7 on the wear resistance test device, and fix both ends of the tubular film-coated product 7 through the wear resistance test device.

[0053] Step S2: Drilling, drill a through hole 8 in the tubular film-coated product 7.

[0054] Step S3: Second fixation, the wear resistance test device fixes the tubular film-coated product 7 through the through hole 8.

[0055] Step S4: Detection, use the wear resistance test device to perform translational wear resistance detection and rotational wear resistance detection on the tubular film-coated product 7, and evaluate the wear resistance of the tubular film-coated product 7 through a surface profiler.

[0056] It should be noted here that in the actual production and manufacturing process, a workpiece that can rotate around the axis of the tubular product usually needs to be installed inside the tubular product, or a workpiece that can move along the axis of the tubular product usually needs to be installed inside the tubular product, such as a telescopic rod, etc. In order to improve the wear resistance of the inner side of the tubular product, a film is usually coated on the inner side of the tubular product. However, when detecting the wear resistance of the inner side of the tubular film-coated product 7, the related technical field can only detect the translational wear resistance or rotational wear resistance of the tubular film-coated product 7, that is, it is impossible to detect the translational wear resistance or rotational wear resistance of the tubular film-coated product 7 at the same time, which is inconvenient to use.

[0057] The wear resistance test method for the film-coated product provided by this application can fix the tubular film-coated product 7 through the first fixation, and can prevent the tubular film-coated product 7 from rotating or moving during the drilling process, which is convenient for the drilling machine to drill. After drilling is completed, the second clamping mechanism 3 is used to perform second fixation on the tubular film-coated product 7. After the second fixation is completed, when detecting the translational wear resistance or rotational wear resistance of the tubular film-coated product 7 through the test mechanism, it can prevent the test mechanism from driving the tubular film-coated product 7 to move and affect the detection effect and test efficiency.

[0058] As Figures 1 to 8As shown, the present application also provides a wear resistance test device, including a frame 1, a drilling machine (not shown in the figure), two first clamping mechanisms 2, a second clamping mechanism 3, and a test mechanism (not shown in the figure). The drilling machine is installed on the frame 1. The two first clamping mechanisms 2 are both installed on the frame 1 and respectively clamp the two ends of the tubular coated product 7. The second clamping mechanism 3 is installed on the frame 1 and is located between the two first clamping mechanisms 2, and is further configured to fix the tubular coated product 7 through the through hole 8. The test mechanism includes a translation component 4, a rotation component 5, and two grinding components 6. The translation component 4 is installed on the frame 1, the rotation component 5 is installed on the frame 1 and is located at one end of the tubular coated product 7 away from the translation component 4. One of the grinding components 6 is installed on the translation component 4 and abuts against the inner side of the tubular coated product 7, and reciprocates along the first direction under the drive of the translation component 4. The other grinding component 6 is installed on the rotation component 5 and abuts against the inner side of the tubular coated product 7, and rotates around the first direction under the drive of the rotation component 5.

[0059] It should be noted here that the first direction above and below refers to the axial direction of the structure of the tubular coated product 7 itself, specifically the X-axis as described in Figure 1 the above.

[0060] For the wear resistance test device provided by the present application, through the two first clamping mechanisms 2, the two ends of the tubular coated product 7 can be fixed. When using the drilling machine to drill holes in the tubular coated product 7, the situation that the tubular coated product 7 rotates or moves can be prevented, which is convenient for the drilling machine to drill holes and reduces the drilling difficulty. After the drilling is completed, the second clamping mechanism 3 fixes the tubular coated product 7 through the through hole 8. When using the test mechanism to grind the inner side of the tubular coated product 7, the situation that the tubular coated product 7 rotates or moves relative to the first clamping mechanism 2 can be prevented. Compared with fixing the tubular coated product 7 through the first clamping mechanism 2, the second clamping mechanism 3 can completely fix the tubular coated product 7, and the fixing effect is better, which helps to improve the detection effect and test efficiency of the wear resistance test device. With the cooperation of the translation component 4 and the grinding component 6, the translation component 4 can drive the grinding component 6 to reciprocate along the first direction on the inner side of the tubular coated product 7, so as to perform translational wear resistance detection on the inner side of the tubular coated product 7. With the cooperation of the rotation component 5 and the grinding component 6, the rotation component 5 can drive the grinding component 6 to rotate around the first direction on the inner side of the tubular coated product 7, so as to perform rotational wear resistance detection on the inner side of the tubular coated product 7.

[0061] In an embodiment of the present application, please refer to Figures 1 to 8, the grinding assembly 6 includes a first adjusting member 61, a second adjusting member 62 and a plurality of grinding columns 63. The first adjusting member 61 is installed on the translation assembly 4 or the rotation assembly 5. The second adjusting member 62 is installed on the first adjusting member 61 and moves along the first direction driven by the first adjusting member 61. The plurality of grinding columns 63 are all installed on the second adjusting member 62 and move towards each other or away from each other driven by the second adjusting member 62.

[0062] It should be noted here that in this embodiment, the number of the grinding columns 63 is set to four as an example for illustration. Of course, in other embodiments, according to actual application requirements, the number of the grinding columns 63 can also be set to two, three, five... other numbers, which is not uniquely limited here.

[0063] With such a setting, the first adjusting member 61 can drive the plurality of grinding columns 63 to move along the first direction. In the actual application process, the tester can adjust the position of the grinding columns 63 according to the distance between the grinding columns 63 and the tubular film product 7, so that the grinding columns 63 can always be located inside the tubular film product 7 during the grinding process, ensuring the detection effect of the wear resistance test device; and, under the action of the first adjusting member 61, the grinding columns 63 can be applied to tubular film products 7 of different lengths, improving the applicable range of the wear resistance test device. The second adjusting member 62 can drive the plurality of grinding columns 63 to move towards each other or away from each other. In the actual application process, the tester can adjust the position of the plurality of grinding columns 63 in the radial direction of the tubular film product 7 according to the inner diameter of the tubular film product 7, so that the plurality of grinding columns 63 can always abut against the inner side of the tubular film product 7, ensuring the detection effect of the wear resistance test device; and, under the action of the second adjusting member 62, the grinding columns 63 can be applied to tubular film products 7 of different diameters, further improving the applicable range of the wear resistance test device.

[0064] In an embodiment of the present application, please refer to Figures 1 to 8 , the first adjusting member 61 includes a fixing plate 611, a plurality of adjusting screws 612, an adjusting plate 613, a plurality of first adjusting nuts 614 and a plurality of second adjusting nuts 615. The fixing plate 611 is installed on the translation assembly 4 or the rotation assembly 5. The plurality of adjusting screws 612 are all passed through the fixing plate 611 and are arranged at intervals. The adjusting plate 613 is connected to one end of the plurality of adjusting screws 612 and is located on the side of the fixing plate 611 facing the second adjusting member 62. The plurality of first adjusting nuts 614 are screwed onto the plurality of adjusting screws 612 and are located on the side of the fixing plate 611 facing away from the second adjusting member 62 and are arranged in one-to-one correspondence with the plurality of adjusting screws 612. The plurality of second adjusting nuts 615 are screwed onto the plurality of adjusting screws 612 and are located on the side of the fixing plate 611 facing the second adjusting member 62 and are arranged in one-to-one correspondence with the plurality of adjusting screws 612.

[0065] It should be noted here that in this embodiment, the number of the first adjusting nuts 614 and the number of the second adjusting nuts 615 are both set to four as an example for illustration. Of course, in other embodiments, according to actual application requirements, the first adjusting nuts 614 and the second adjusting nuts 615 can also be set to two, three, five... other numbers, which are not uniquely limited herein.

[0066] With such a setting, the tester can adjust the positions of the first adjusting nut 614 and the second adjusting nut 615 on the adjusting screw 612 by rotating the first adjusting nut 614 and the second adjusting nut 615. By adjusting the positions of the first adjusting nut 614 and the second adjusting nut 615 on the adjusting screw 612, the tester can adjust the position of the adjusting plate 613, and further can adjust the positions of the multiple grinding columns 63 in the first direction, so that the grinding columns 63 can be applicable to tubular coated products 7 of different lengths. Moreover, under the action of the first adjusting nut 614, the second adjusting nut 615 and the adjusting screw 612, self-locking can be achieved, which helps to improve the structural stability between the adjusting plate 613 and the fixing plate 611, and makes the adjusting plate 613 not easy to move relative to the fixing plate 611. During the grinding process, the grinding columns 63 can stably grind the inner side of the tubular coated product 7, which helps to improve the detection effect and test efficiency of the wear-resistant test device.

[0067] In an embodiment of the present application, refer to Figures 1 to 8 , the second adjusting member 62 includes a central shaft 621 and a spline groove 622. The central shaft 621 is connected to the side of the adjusting plate 613 facing away from the fixing plate 611, and the spline groove 622 is formed in the adjusting plate 613 and the central shaft 621. The first adjusting member 61 further includes a spline rod 616. The spline rod 616 is connected to the fixing plate 611 and is slidably clamped in the spline groove 622.

[0068] With such a setting, when the rotating assembly 5 drives the multiple grinding columns 63 to rotate, through the spline groove 622 and the spline rod 616, compared with the use of the adjusting screw 612 to transmit force between the fixing plate 611 and the adjusting plate 613, the force transmission of the spline groove 622 and the spline rod 616 is more stable and not easy to shake, so that the grinding columns 63 can more stably grind the inner side of the tubular coated product 7, which helps to improve the detection effect and test efficiency of the wear-resistant test device. Moreover, under the action of the spline groove 622 and the spline rod 616, it helps to further improve the structural stability between the fixing plate 611 and the adjusting plate 613, and enables the adjusting plate 613 to move relative to the fixing plate 611 along the first direction.

[0069] In an embodiment of the present application, please refer to Figures 1 to 8, the second adjusting member 62 includes a central shaft 621, an adjusting sleeve 623, a slider 624, a plurality of first hinge rods 625, a plurality of second hinge rods 626 and a plurality of third hinge rods 627. The central shaft 621 is connected to the first adjusting member 61. The adjusting sleeve 623 is screwed onto the central shaft 621. The slider 624 is sleeved on the central shaft 621 and is located at one end of the adjusting sleeve 623 away from the first adjusting member 61. A plurality of first hinge rods 625 are hinged between a plurality of grinding columns 63 and the slider 624 and are arranged in one-to-one correspondence with the plurality of grinding columns 63. A plurality of second hinge rods 626 are hinged between a plurality of grinding columns 63 and the central shaft 621 and are arranged in one-to-one correspondence with the plurality of grinding columns 63. A plurality of third hinge rods 627 are hinged between a plurality of grinding columns 63 and the central shaft 621 and are arranged in one-to-one correspondence with the plurality of grinding columns 63. Among them, the second hinge rod 626 and the third hinge rod 627 are arranged in parallel.

[0070] It should be noted here that in this embodiment, the number of the first hinge rods 625, the number of the second hinge rods 626 and the number of the third hinge rods 627 are all set to four as an example for illustration. Of course, in other embodiments, according to actual application requirements, the number of the first hinge rods 625, the second hinge rods 626 and the third hinge rods 627 can also be set to two, three, five... other numbers, which are not uniquely limited here.

[0071] With such a setting, an isosceles structure can be formed by enclosing the central shaft 621, the first hinge rod 625 and the second hinge rod 626. By rotating the adjusting sleeve 623, the tester can change the position of the adjusting sleeve 623 on the central shaft 621, thereby changing the position of the slider 624 on the central shaft 621. When the slider 624 moves in the first direction, the first hinge rod 625 and the second hinge rod 626 can rotate towards each other or away from each other. A parallelogram structure can be formed by enclosing the central shaft 621, the grinding column 63, the second hinge rod 626 and the third hinge rod 627. By driving the first hinge rod 625 and the second hinge rod 626 to rotate towards each other or away from each other, the tester can change the position of the grinding column 63 in the radial direction of the tubular film product 7, so that the grinding column 63 can closely adhere to the inner side of the tubular film product 7, which helps to improve the grinding effect, detection effect and test efficiency of the wear-resistant test device; and, the tester can also adjust the position of the grinding column 63 according to the diameter of the tubular film product 7, which helps to improve the applicable range of the wear-resistant test device.

[0072] In an embodiment of the present application, please refer to Figures 1 to 8 , the translation assembly 4 includes a reciprocating driver 41 and a third adjusting member 42. The third adjusting member 42 is installed between the grinding assembly 6 and the reciprocating driver 41 and reciprocates along the first direction under the drive of the reciprocating driver 41.

[0073] With such a setting, when detecting the translational wear resistance of the tubular coated product 7, the third adjusting member 42 can drive the polishing column 63 to rotate on the inner peripheral side of the tubular coated product 7, so as to change the position of the polishing column 63 on the inner peripheral side of the tubular coated product 7, and further detect the parallel wear resistance at different positions on the inner peripheral side of the tubular coated product 7, which helps to improve the detection range of the wear resistance test device.

[0074] In an embodiment of the present application, refer to Figures 1 to 8 , the third adjusting member 42 includes a mounting plate 421, a mounting cover 422, a first rotating plate 423, a plurality of pin holes 424, a plug pin 425, a rotating rod 426 and a second rotating plate 427. The mounting plate 421 is mounted on the output end of the reciprocating driver 41, the mounting cover 422 is mounted on the mounting plate 421, the first rotating plate 423 is rotatably mounted in the mounting cover 422 and is located between the mounting plate 421 and the mounting cover 422. The plurality of pin holes 424 are all opened on the outer peripheral side of the first rotating plate 423 and are arranged at intervals. The plug pin 425 passes through the mounting cover 422 and is inserted into any one of the pin holes 424. The rotating rod 426 is connected to the first rotating plate 423 and passes through the mounting cover 422. The second rotating plate 427 is connected to the end of the rotating rod 426 away from the first rotating plate 423 and is mounted on the polishing assembly 6.

[0075] With such a setting, during the test, the tester pulls out the plug pin 425, which can change the polishing position of the polishing column 63, helping to improve the detection range of the wear resistance test device. With the cooperation of the plug pin 425 and the pin holes 424, it can prevent the polishing column 63 from rotating relative to the tubular coated product 7 during translational polishing, so that the polishing column 63 can stably polish the tubular coated product 7. Under the action of the rotating rod 426, the distance between the first rotating plate 423 and the second rotating plate 427 can be increased. Compared with the case where the rotating rod 426 is not provided, it can avoid the interference of the adjustment of the adjusting plate 613 due to the too small distance between the first rotating plate 423 and the second rotating plate 427, ensuring that the adjusting plate 613 can be normally adjusted. Through the mounting plate 421 and the mounting cover 422, the normal rotation of the first rotating plate 423 can be ensured.

[0076] In an embodiment of the present application, please refer to Figures 1 to 8 , the first clamping mechanism 2 includes a first lower clamping plate 21, a plurality of first screw rods 22, a first upper clamping plate 23 and a plurality of first nuts 24. The first lower clamping plate 21 is slidably mounted on the frame 1. The plurality of first screw rods 22 are all connected to the first lower clamping plate 21 and are arranged at intervals. The first upper clamping plate 23 is slidably sleeved on the plurality of first screw rods 22. The plurality of first nuts 24 are screwed on the plurality of first screw rods 22 and are located on the side of the first upper clamping plate 23 facing away from the first lower clamping plate 21 and are arranged in one-to-one correspondence with the plurality of first screw rods 22.

[0077] It should be noted here that in this embodiment, the number of the first screws 22 and the number of the first nuts 24 are both set to two as an example for illustration. Of course, in other embodiments, according to actual application requirements, the number of the first screws 22 and the first nuts 24 can also be set to three, four, five... other numbers, which are not uniquely limited here.

[0078] With such a setting, the tester can tightly screw a plurality of first nuts 24 to stably clamp the tubular film-covered product 7 between the first upper clamping plate 23 and the first lower clamping plate 21, so as to facilitate the drilling machine to drill holes in the tubular film-covered product 7, greatly reducing the drilling difficulty. Moreover, the first upper clamping plate 23 is directly sleeved on a plurality of first screws 22, and the tester can adjust the distance between the first upper clamping plate 23 and the first lower clamping plate 21 by rotating a plurality of first nuts 24, so as to be able to clamp tubular film-covered products 7 with different diameters, which helps to improve the application range of the wear-resistant test device.

[0079] Optionally, the first lower clamping plate 21 includes a first lower connecting plate 211, two first lower inclined plates 212, two first lower ear plates 213 and two first wedge-shaped blocks 214. The two first lower inclined plates 212 are connected to both ends of the first lower connecting plate 211. The two first lower ear plates 213 are respectively connected to the two first lower inclined plates 212, are respectively located at one end of the first lower inclined plates 212 far from the first lower connecting plate 211, and are arranged in one-to-one correspondence. The two first wedge-shaped blocks 214 are respectively connected to the two first lower ear plates 213 and are arranged in one-to-one correspondence. The frame 1 includes a base 11 and two wedge-shaped grooves 12. The two wedge-shaped grooves 12 are both opened in the base 11 and are arranged at intervals. Wherein, the two first wedge-shaped blocks 214 are slidably clamped in the two wedge-shaped grooves 12 and are arranged in one-to-one correspondence.

[0080] With such a setting, a groove can be formed by enclosing the first lower connecting plate 211 and the two first lower inclined plates 212. When fixing the tubular film-covered product 7, the groove can be used to preliminarily limit the position of the tubular film-covered product 7, and can prevent the tubular film-covered product 7 from rolling on the surface of the first lower clamping plate 21. When placing the tubular film-covered product 7, through the two first wedge-shaped blocks 214 and the two wedge-shaped grooves 12, the first lower clamping plate 21 and the base 11 can be slidably connected, and the first lower clamping plate 21 can adjust its position on the base 11 according to the tubular film-covered product 7, so as to ensure that the first lower clamping plate 21 is always located at the end of the tubular film-covered product 7. Moreover, after the first clamping mechanism 2 fixes the tubular film-covered product 7, through the two first wedge-shaped blocks 214 and the two wedge-shaped grooves 12, the first clamping mechanism 2 can be clamped and connected to the frame 1, which helps to improve the structural stability between the first clamping mechanism 2 and the frame 1, so that the first clamping mechanism 2 can more stably clamp the tubular film-covered product 7.

[0081] Optionally, the first upper clamping plate 23 includes a first upper connecting plate 231, two first upper inclined plates 232, and two first upper ear plates 233. The two first upper inclined plates 232 are connected to both ends of the first upper connecting plate 231. The two first upper ear plates 233 are respectively connected to the two first upper inclined plates 232, are respectively located at one end of the first upper inclined plates 232 away from the first upper connecting plate 231, and are arranged in one-to-one correspondence.

[0082] With such an arrangement, a groove can be formed by enclosing the first upper connecting plate 231 and the two first upper inclined plates 232. When fixing the tubular film-covered product 7, the groove can further limit the tubular film-covered product 7, and can prevent the tubular film-covered product 7 from rolling between the first upper clamping plate 23 and the first lower clamping plate 21. With the cooperation of the groove formed by the first lower clamping plate 21, the fixing effect of the first clamping mechanism 2 on the tubular film-covered product 7 is effectively improved.

[0083] In an embodiment of the present application, please refer to Figures 1 to 8 , the second clamping mechanism 3 includes a second lower clamping plate 31, a plurality of second screw rods 32, a second upper clamping plate 33, a plurality of second nuts 34, a third screw rod 35, and a third nut 36. The second lower clamping plate 31 is slidably installed on the frame 1. The plurality of second screw rods 32 are all connected to the second lower clamping plate 31 and are arranged at intervals. The second upper clamping plate 33 is slidably sleeved on the plurality of second screw rods 32. The plurality of second nuts 34 are screwed onto the plurality of second screw rods 32 and are located on the side of the second upper clamping plate 33 facing away from the second lower clamping plate 31, and are arranged in one-to-one correspondence with the plurality of second screw rods 32. The third screw rod 35 passes through the second lower clamping plate 31 and the second upper clamping plate 33, and passes through the through hole 8. The third nut 36 is screwed onto the third screw rod 35 and is located on the side of the second upper clamping plate 33 facing away from the second lower clamping plate 31.

[0084] With such an arrangement, the tester can make the tubular film-covered product 7 be clamped more stably between the second upper clamping plate 33 and the second lower clamping plate 31 by tightening the plurality of second nuts 34, so as to facilitate the testing mechanism to detect the translational wear resistance and rotational wear resistance of the tubular film-covered product 7. Moreover, the second upper clamping plate 33 is directly sleeved on the plurality of second screw rods 32. The tester can adjust the distance between the second upper clamping plate 33 and the second lower clamping plate 31 by rotating the plurality of second nuts 34, so as to be able to clamp tubular film-covered products 7 with different diameters, which helps to improve the applicable range of the wear resistance test device. In addition, after the tubular film-covered product 7 is fixed by using the second clamping mechanism 3, compared with the first clamping mechanism 2, the third screw rod 35 passes through the second lower clamping plate 31, the tubular film-covered product 7, and the second upper clamping plate 33. The third screw rod 35 and the third nut 36 can completely fix the tubular film-covered product 7, and the fixing effect is better.

[0085] Optionally, the second lower clamping plate 31 includes a second lower connecting plate 311, two second lower inclined plates 312, two second lower ear plates 313, and two second wedge blocks 314. The two second lower inclined plates 312 are connected to both ends of the second lower connecting plate 311. The two second lower ear plates 313 are respectively connected to the two second lower inclined plates 312, and are respectively located at one end of the second lower inclined plates 312 away from the second lower connecting plate 311, and are arranged in one-to-one correspondence. The two second wedge blocks 314 are respectively connected to the two second lower ear plates 313, and are arranged in one-to-one correspondence. Among them, the two second wedge blocks 314 are slidably clamped in the two wedge grooves 12, and are arranged in one-to-one correspondence.

[0086] It should be noted here that during the translation wear resistance test, when the acting force of the reciprocating driver 41 is relatively large, the tester can install wedge blocks (not shown in the figure) into the wedge grooves 12 and fix the wedge blocks in the wedge grooves 12 with bolts to prevent the first clamping mechanism 2 and the second clamping mechanism 3 from sliding.

[0087] With such a setting, a groove can be formed by enclosing the second lower connecting plate 311 and the two second lower inclined plates 312. When fixing the tubular coated product 7, the tubular coated product 7 can be further limited by the groove. When placing the tubular coated product 7, through the two second wedge blocks 314 and the two wedge grooves 12, the second lower clamping plate 31 and the base 11 can be slidably connected, and the second lower clamping plate 31 can adjust its position on the base 11 according to the tubular coated product 7, so as to ensure that the second lower clamping plate 31 is always located in the middle of the tubular coated product 7. Moreover, after the tubular coated product 7 is fixed by using the second clamping mechanism 3, through the two second wedge blocks 314 and the two wedge grooves 12, the second clamping mechanism 3 can be clamped and connected to the frame 1, which helps to improve the structural stability between the second clamping mechanism 3 and the frame 1, so that the second clamping mechanism 3 can clamp the tubular coated product 7 more stably.

[0088] Optionally, the second upper clamping plate 33 includes a second upper connecting plate 331, two second upper inclined plates 332, and two second upper ear plates 333. The two second upper inclined plates 332 are connected to both ends of the second upper connecting plate 331. The two second upper ear plates 333 are respectively connected to the two second upper inclined plates 332, and are respectively located at one end of the second upper inclined plates 332 away from the second upper connecting plate 331, and are arranged in one-to-one correspondence.

[0089] With such a setting, a groove can be formed by enclosing the second upper connecting plate 331 and the two second upper inclined plates 332. When fixing the tubular film-coated product 7, the groove can further limit the tubular film-coated product 7, and can prevent the tubular film-coated product 7 from rolling between the second upper clamping plate 33 and the second lower clamping plate 31. With the cooperation of the groove formed by the second lower clamping plate 31, the fixing effect of the second clamping mechanism 3 on the tubular film-coated product 7 is effectively improved.

[0090] The working principle of the wear-resistant test device provided by this application is as follows: The tester first places the tubular coated product 7 at the two first lower clamping plates 21. The tester adjusts the distance between the two first lower clamping plates 21 according to the length of the tubular coated product 7 and through the wedge-shaped groove 12 and the first wedge-shaped block 214 until the two first lower clamping plates 21 respectively move to both ends of the tubular coated product 7. The tester sleeves the first upper clamping plate 23 on the first screw rod 22 and uses the first nut 24 to fix the first upper clamping plate 23; similarly, another first upper clamping plate 23 is installed at the first lower clamping plate 21. At this time, the tubular coated product 7 is clamped by the two first clamping mechanisms 2. The tester uses a drilling machine to drill a hole in the middle of the tubular coated product 7 (that is, between the two first clamping mechanisms 2). After drilling the through hole 8, the tester moves the second lower clamping plate 31 to the through hole 8 and fixes the second upper clamping plate 33 to the second lower clamping plate 31 through the second screw rod 32 and the second nut 34. The tester then passes the third screw rod 35 through the second lower clamping plate 31, the tubular coated product 7, and the second upper clamping plate 33 in sequence, and finally uses the third nut 36 to fix the third screw rod 35. After fixing the tubular coated product 7, the test mechanism can be used to detect the wear-resistant performance of the tubular coated product 7. When detecting the rotational wear-resistant performance of the tubular coated product 7, the tester changes the distance between the adjusting plate 613 and the fixing plate 611 by rotating the first adjusting nut 614 and the second adjusting nut 615 until the grinding column 63 completely extends into the tubular coated product 7. The tester continues to rotate the adjusting sleeve 623 so that the adjusting sleeve 623 moves away from the adjusting plate 613 in the first direction. The adjusting sleeve 623 drives the slider 624 to move away from the adjusting plate 613 in the first direction. Driven by the slider 624, the first articulated rod 625 and the second articulated rod 626 rotate towards each other, and the third articulated rod 627 rotates synchronously with the second articulated rod 626 until the grinding column 63 abuts against the inner side of the tubular coated product 7. The tester starts the rotating assembly 5, and the rotating assembly 5 drives the grinding column 63 to rotate around the first direction through the first adjusting member 61 and the second adjusting member 62 to achieve rotational grinding. After grinding is completed, the tester uses a surface profiler for evaluation. When detecting the translational wear-resistant performance of the tubular coated product 7, similarly, the tester completely extends the grinding column 63 into the tubular coated product 7 and makes the grinding column 63 abut against the inner side of the tubular coated product 7. The tester starts the reciprocating driver 41, and the reciprocating driver 41 drives the grinding column 63 to reciprocate in the first direction through the third adjusting member 42, the first adjusting member 61, and the second adjusting member 62 to achieve translational grinding. After grinding is completed, the tester uses a surface profiler for evaluation.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of the present application shall be included within the protection scope of the present application.
