[0002] The grinding rod is the main grinding medium in the rod mill. Through the impact, grinding, shearing, and laminar crushing of the grinding rod, the rod mill can effectively grind the material to meet the requirements of different industries for the particle size of the material. Therefore, various properties of the grinding rod need to be detected during the production of the grinding rod, including hardness detection, wear resistance detection, strength detection, metallographic structure detection, and dimensional accuracy detection, etc.

[0003] Usually, workers will use different types of wear resistance testing machines to detect wear resistance. However, most of the current wear resistance testing machines can only simulate specific types of working conditions for detection, such as sliding wear, rolling wear, and abrasive wear, etc. But the actual use environment is often a combination of multiple wear forms. Therefore, in the wear resistance detection of the grinding rod, there will be a large deviation between the detection result and the wear resistance in actual use. Summary of the Invention

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Figure 1 Disclosed is a grinding rod performance testing device for detecting the performance of grinding rod types with different composition components, such as but not limited to chromium alloy grinding rods, ceramic grinding rods, and resin grinding rods. The detection types include sliding wear, rolling wear, abrasive wear, and the composite state of different wear conditions.

[0032] Such as Figure 1 , Figures 9 - 11As shown in the figure, the performance testing device for the grinding rod includes a test bench 1, which is divided into two movable parts. Two clamping cylinders 30 are respectively assembled on the test bench 1, corresponding to the two parts of the test bench 1. A plurality of elastic rubber plates 31 are arranged inside the clamping cylinder 30, presenting an annular array and a linear array assembly method respectively. And in the axial direction of the clamping cylinder 30, the length of the rubber plate 31 closer to the bottom of the cylinder is longer. When grinding rods with different diameters are inserted into the inside of the clamping cylinder 30 for installation, the surface of the rubber plate 31 is first extruded, and the grinding rod is clamped and fixed by the elastic force and friction force of the rubber plate 31, and the applicable diameter range of the grinding rod is also relatively wide. During detection, the clamping cylinder 30 is driven to rotate by an external motor, so as to drive the grinding rod to rotate (the motor is not shown in the figure).

[0033] The surface of the grinding rod is divided into different areas for different working condition types of detection, as well as compound working condition types of detection, including sliding wear working condition, rolling wear working condition, abrasive wear working condition, sliding and rolling wear compound working condition, sliding and abrasive wear compound working condition, and sliding rolling and abrasive wear compound working condition.

[0034] As Figures 2 - 4 As shown in the figure, for the simulation of the sliding wear working condition, it includes a limit ring 6 installed on the surface of one of the clamping cylinders 30 through a bearing to limit the clamping cylinder 30 to prevent its axial displacement, but the limit ring 6 and the clamping cylinder 30 can rotate relative to each other. An L-shaped or U-shaped connecting frame 5 is installed on the surface of the clamping cylinder 30. It should be noted that the connecting frame 5 does not affect the rotation of the clamping cylinder 30. A movable test plate 1 4 is assembled on the surface of the connecting frame 5. The shape of the test plate 1 4 is arc-shaped, fitting on the surface of the grinding rod, and the moving direction of the test plate 1 4 is the axial direction of the grinding rod.

[0035] At the same time, to adapt to grinding rods with different diameters, a height adjustment component is assembled on the surface of the connecting frame 5, including a moving block. A threaded rod is installed on the surface of the moving block, and the test plate 1 4 is installed on the end of the threaded rod through a bearing. The distance between the test plate 1 4 and the surface of the grinding rod is adjusted by rotating the threaded rod. A wavy limit groove 7 is opened on the inner side of the limit ring 6. A sleeve with an inner diameter larger than the diameter of the threaded rod is sleeved on the surface of the threaded rod. The sleeve is assembled with a limit ball 8 through a fixed rod. In this way, it is ensured that when the threaded rod rotates, the limit ball 8 will not rotate along with it. The limit ball 8 is stuck inside the limit groove 7. In order to ensure that the limit ball 8 can move along the inner shape of the limit groove 7, a circular ring groove communicating with the limit groove 7 needs to be opened on one side of the limit ring 6, and the fixed rod is located inside the circular ring groove.

[0036] When the clamping cylinder 30 rotates, it will drive the first test plate 4 and the grinding rod to rotate simultaneously through the connecting frame 5. In order to ensure that the first test plate 4 can generate an axial displacement and simulate the working condition of sliding wear, it is necessary to fix the limit ring 6 to ensure that during the rotation of the first test plate 4, the limit groove 7 generates an axial displacement on the limit ball 8.

[0037] For the types of chromium alloy grinding rods, two symmetrically installed support rods 11 are fixed on the surface of the limit ring 6. It should be noted that the support rods 11 cannot affect the rotation of the connecting frame 5. Two movable U-shaped frames 12 are symmetrically assembled on the surface of the test bench 1. The two ends of the U-shaped frame 12 movably penetrate the surface of the test bench 1. A connecting spring 15 is assembled between the outer surface of the test bench 1 and the U-shaped frame 12. One end of the U-shaped frame 12 is provided with an integrally formed guide rod 14, and the guide rod 14 is inclined and has a guiding effect on the connecting frame 5. The other end of the U-shaped frame 12 is provided with an integrally formed U-shaped plate 13, and one end of the support rod 11 just abuts against the inner side of the U-shaped plate 13. The two guide rods 14 are centrosymmetrically arranged.

[0038] In the initial state, the end of the support rod 11 abuts against the inside of the U-shaped plate 13, thereby limiting the position of the limit ring 6. During the rotation, the connecting frame 5 rotates with the clamping cylinder 30. When it rotates to the surface of the guide rod 14, it squeezes the guide rod 14, indirectly squeezing the U-shaped frame 12, and the U-shaped plate 13 will also move away from the support rod 11. At this time, the connecting spring 15 is in a stretched state until the connecting frame 5 disengages from the guide rod 14. During this process, the U-shaped plate 13 on the symmetric side will still limit the support rod 11. It should also be noted that the inclination degree and length of the guide rod 14 need to ensure that the connecting frame 5 can pass through the U-shaped frame 12 smoothly and prevent the connecting frame 5 from being stuck inside the U-shaped frame 12. When the connecting frame 5 disengages from the guide rod 14, the resilience of the connecting spring 15 will make the U-shaped frame 12 return to the initial position, thereby realizing the limit again until the connecting frame 5 rotates to the U-shaped frame 12 at the symmetric position and continues to repeat the above operations.

[0039] For the types of ceramic grinding rods and resin grinding rods, since these types of grinding rods do not contain iron components, a magnetic attraction plate 9 is assembled at the bottom of the limit ring 6. Similarly, the magnetic attraction plate 9 does not affect the rotation of the connecting frame 5. An electromagnet 10 is assembled on the surface of the test bench 1, and the electromagnet 10 and the magnetic attraction plate 9 are located on the same vertical line. When the electromagnet 10 is energized, the generated magnetism will have an adsorption effect on the magnetic attraction plate 9, which is equivalent to providing a continuous downward pulling force on the limit ring 6, thereby ensuring the stability of the limit ring 6 and indirectly ensuring the stability of the axial displacement. However, since the magnetic attraction force of the electromagnet 10 will affect the grinding rods containing iron, cobalt, and nickel components, this implementation method is for grinding rods without iron, cobalt, and nickel components.

[0040] As Figure 1and Figure 5 As shown, for the simulation of rolling wear conditions, it is only necessary to assemble a fixing frame 17 on the surface of the test bench 1, and also assemble a height adjustment assembly on the fixing frame 17, including a threaded rod threadedly mounted on the fixing frame 17, and a test plate 2 16 is movably mounted on the end of the threaded rod through a bearing, and the test plate 2 16 is tightly attached to the surface of the grinding rod. The distance between the test plate 2 16 and the grinding rod is adjusted by the height adjustment assembly. During the rotation of the grinding rod, the test plate 2 16 does not move, thereby realizing the simulation of rolling wear conditions.

[0041] like Figure 6 and Figure 8 As shown, for the simulation of abrasive wear conditions, it is necessary to fix an abrasive frame 18 on the surface of the test bench 1 through supporting legs, the inside of the abrasive frame 18 needs to be filled with abrasives used in actual production, through holes 19 are provided on both sides of the abrasive frame 18, and removable leak-proof plates 20 are installed on both sides of the inside of the abrasive frame 18, and the grinding rod moves through the surface of the leak-proof plates 20. Similarly, different leak-proof plates 20 are replaced for grinding rods of different diameters. During the rotation of the grinding rod, the abrasive will rub against the grinding rod, thereby realizing the simulation of abrasive wear conditions.

[0042] like Figures 6 - 9 As shown, it is aimed at complex sliding and rolling wear combined conditions, sliding and abrasive wear combined conditions, and sliding rolling and abrasive wear combined conditions.

[0043] A movable detection frame 2 is assembled on the surface of the test bench 1, and an abrasive frame 18 is also assembled on the surface of the detection frame 2, and corresponding through holes 19 are opened, and leak-proof plates 20 for abrasives of different diameters are installed. A rotatable long rod 21 is assembled inside the detection frame 2, and the surfaces of the long rod 21 and the clamping cylinder 30 are fixedly sleeved with a gear 22, and the two gears 22 are connected by rotating a gear 23 installed on the surface of the test bench 1. It should be noted that the length of the gear 22 on the long rod 21 is less than the length of the gear 22 on the clamping cylinder 30, and the length of the gear 23 is the same as the length of the gear 22 on the clamping cylinder 30, so as to ensure that during the movement of the detection frame 2, the gear 22 and the gear 23 can still maintain a stable meshing state, and when the detection frame 2 moves, it will drive the abrasive frame 18 to move, thereby simulating the composite situation of sliding and abrasive working conditions.

[0044] A test rod 3 is provided in close contact with the surface of the grinding rod. A short rod 24 penetrates through the center position of the test rod 3. Gear three 25 is fixedly sleeved on the surfaces of both the short rod 24 and the long rod 21. The two gear three 25 are drivingly connected by a transmission belt 26. Collar 27 is sleeved on the surfaces of both the long rod 21 and the short rod 24. The collar 27 is fixedly installed through bearings. A connecting rod 28 formed integrally is provided between the two collars 27. At this time, it can be ensured that when the long rod 21 rotates, it can also drive the test rod 3 to rotate to simulate the rolling wear working condition. At the same time, the long rod 21 moves along with the detection frame 2, and the test rod 3 will also move along with the detection frame 2 to simulate the combined working condition of sliding and rolling wear. During the reciprocating movement of the detection frame 2, the test rod 3 moves to the working condition area simulated by the abrasive frame 18. The two overlapping simulated areas are the combined working condition areas of sliding, rolling and abrasive wear. Conducting separate simulations and combined simulations of different working conditions on the same grinding rod at the same time can more intuitively and realistically reflect the wear conditions of the grinding rod in different working states, making the detection results closer to the actual use results.

[0045] In order to be applicable to grinding rods of different diameters, the lower end of the connecting rod 28 extends below the long rod 21. A movable pressing rod 29 is assembled on the surface of the detection frame 2. The pressing rod 29 can be driven to move by rotating a threaded rod or an electric push rod. The pressing rod 29 abuts against the surface of the extended position of the connecting rod 28. The connecting rod 28 is rotated by the pressing force of the pressing rod 29 to ensure that the test rod 3 can abut against the surfaces of grinding rods of different diameters.
