[0002] Polyamide (PA, commonly known as nylon) is a resin first developed by the American DuPont Corporation for fiber use. It was industrialized in 1939 and PA composite materials can be used in the automotive industry.
[0003] Before using PA composite materials, it is necessary to conduct wear resistance testing on PA composite materials to see whether they can maintain good wear resistance after long-term wear. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a PA composite material wear resistance detection device for solving the technical problem of detecting whether the PA composite material has good wear resistance.
[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

DETAILED DESCRIPTION
[0015] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0016] Example:
[0017] like Figure 1 As shown, a PA composite material wear resistance testing device includes a first support plate 22 and a second support plate 15. The second support plate 15 is fixedly mounted on one end of the first support plate 22. A grinding piece for grinding the composite material is provided on one end of the first support plate 22. An adjustable and rotatable mounting frame is provided on one end of the second support plate 15. A protective frame 11 for limiting the movement of the composite material is fixed on the mounting frame. A pushing plate 12 for applying pressure to the composite material is provided in the protective frame 11.
[0018] After cutting the PA composite material to be detected into a shape that fits the inner wall of the protection frame 11, place the PA composite material into the protection frame 11. Rotate the mounting frame, and the mounting frame drives the PA composite material to rotate through the protection frame 11, so that one end of the PA composite material abuts against the grinding piece. Push the push plate 12 to always press on the PA composite material. Start the grinding piece, and the grinding piece grinds the PA composite material. After grinding, take out the PA composite material, compare the polished area and the unpolished area of the PA composite material, and use this method to detect the wear resistance of the PA composite material.
[0019] As Figure 1 shown, the grinding piece includes a grinding motor 23, a driving shaft 24 and a grinding disc 25. The grinding motor 23 is fixedly arranged at the top end of the first support plate 22. The driving shaft 24 is power-connected to the output end of the grinding motor 23. The grinding disc 25 is fixedly arranged at the end of the driving shaft 24. During use, the grinding disc 25 can be replaced according to the actual use situation.
[0020] As Figure 1 and Figure 3 shown, two mounting blocks 17 are symmetrically and fixedly arranged at one end of the second support plate 15. A connecting shaft 18 is rotatably arranged between the two mounting blocks 17. The mounting frame is fixedly arranged on the connecting shaft 18. A working motor 16 is fixedly arranged at one end of the second support plate 15. The working motor 16 is power-connected to the end of the connecting shaft 18 extending out of the mounting block 17. The rotation angle of the connecting shaft 18 is adjusted through the working motor 16, so as to adjust the angle of the mounting frame. When the mounting frame is at an upward-inclined angle, it is convenient for the user to put the PA composite material to be polished into the protection frame 11. When the mounting frame is in a horizontal state, it is convenient for the grinding piece to grind the PA composite material to be polished.
[0021] As Figure 1 shown, the mounting frame includes a first connecting rod 19, a second connecting rod 20, a third connecting rod 21 and a carrier plate 14. The first connecting rod 19 is fixedly arranged on the connecting shaft 18. The second connecting rod 20 is fixedly arranged at the end of the first connecting rod 19. The third connecting rod 21 is fixedly arranged at the end of the second connecting rod 20. The carrier plate 14 is fixedly arranged at the other end of the second connecting rod 20. The carrier plate 14 is arranged above the third connecting rod 21. The protection frame 11 is fixedly arranged at the end of the third connecting rod 21. A protection cavity 10 is vertically and throughly opened in the protection frame 11. A cylinder 13 is fixedly arranged at the bottom end of the carrier plate 14. The push plate 12 is fixedly arranged at the telescopic end of the cylinder 13. The outer periphery of the push plate 12 is in contact with the inner wall of the protection cavity 10.
[0022] As Figure 2 shown, two first stress shafts 29 are rotatably arranged on the outer periphery of the protection frame 11. First blocking blocks 26 are fixedly arranged at the ends of the first stress shafts 29. Two second stress shafts 30 are rotatably arranged at the bottom end of the protection frame 11. Second blocking blocks 31 are fixedly arranged at the ends of the second stress shafts 30.
[0023] As shown Figure 1 and Figure 2 As shown, two limiting plates 28 are hinged on the protection frame 11. Limiting grooves 27 are formed on the limiting plates 28. The length and width of the limiting grooves 27 are different. Thus, after the first blocking block 26 and the second blocking block 31 rotate a certain angle, the first blocking block 26 and the second blocking block 31 can pass through the limiting grooves 27. After the first blocking block 26 and the second blocking block 31 rotate a certain angle again, the first blocking block 26 and the second blocking block 31 cannot pass through the limiting grooves 27, thereby limiting the position of the limiting plates 28. When the limiting plates 28 are in a horizontal state, they can prevent the PA composite material to be detected from falling out of the protection cavity 11.
[0024] Working principle:
[0025] Start the working motor 16. The working motor 16 drives the first connecting rod 19 to rotate through the connecting shaft 18. The first connecting rod 19 drives the protection frame 11 to rotate through the third connecting rod 21. After the protection frame 11 rotates to a certain angle, the protection frame 11 tilts upward. Put the cut PA composite material to be detected into the protection cavity 10. Rotate the first force-bearing shaft 29 through the first blocking block 26 to make the limiting plate 28 separate from the first blocking block 26. Rotate the limiting plate 28 to make the second blocking block 31 and the second force-bearing shaft 30 pass through the limiting groove 27. Then rotate the second blocking block 31 to fix the limiting plate 28. Start the working motor 16. The working motor 16 drives the first connecting rod 19 to rotate through the connecting shaft 18. The first connecting rod 19 drives the protection frame 11 to rotate through the third connecting rod 21. After the protection frame 11 rotates to a certain angle, the protection frame 11 is in a horizontal state, making one end of the PA composite material to be detected abut against one end of the grinding disc 25. Rotate the second blocking block 31 and the second force-bearing shaft 30 to make the limiting plate 28 separate from the second blocking block 31. Rotate the limiting plate 28 to make the first blocking block 26 and the first limiting shaft 29 pass through the limiting groove 27. Rotate the first blocking block 26 to fix the limiting plate 28. Start the cylinder 13. The cylinder 13 pushes the pushing plate 12 to move downward. The pushing plate 12 always presses on the PA composite material. Start the grinding motor 23. The grinding motor 23 drives the grinding disc 25 to rotate through the driving shaft 24. The grinding disc 25 grinds the PA composite material. After grinding for a period of time, take out the PA composite material and compare the grinding area and the ungrinded area.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
