Description

Technical Field

[0001] This utility model relates to the field of material wear testing technology, specifically to a wear testing device for composite materials. Background Technology

[0002] Composite material wear testing refers to evaluating the wear performance of composite materials under specific conditions through a series of experimental methods and equipment. This test aims to simulate the wear of materials in actual use, thereby understanding their durability and service life. Currently, wear testing is often required in the production process of tungsten carbide reinforced steel matrix composites.

When it is necessary to compare the wear performance of two sets of tungsten carbide reinforced steel matrix composite materials produced under different processes, separate wear tests are usually required, which often requires a lot of time and effort and affects the efficiency of the testing work.

[0023] Example 1:

[0024] Please see Figures 1-4As shown, this utility model provides a wear testing device for composite materials, including a support platform 1 and a fixed frame 8. A stepper motor 25 is fixedly installed on the right end of the front surface of the fixed frame 8, and a drive roller 26 is fixedly installed on the output end of the stepper motor 25. An abrasive belt 28 is connected to the surface of the drive roller 26. A rotating shaft 15 is movably connected to the left side of the support platform 1 via a bearing. A first bevel gear 14 is fixedly installed on the right side of the rotating shaft 15. A first rotating sleeve 6 is movably connected to the left end of the support platform 1 via a bearing. A second bevel gear 16 is fixedly installed at the middle end of the first rotating sleeve 6, and a first bevel gear 14 is threaded to the top of the first rotating sleeve 6. The screw 7 has a lifting plate 9 fixedly connected to its top. A pressure sensor 13 is fixedly installed between the middle end of the lifting plate 9 and the top of the fixed frame 8. A worm gear 2 is movably connected to the front surface of the support platform 1 via a bearing. A rotating rod 20 is movably connected to the middle end of the inner cavity of the support platform 1 via a bearing. A worm wheel 19 is fixedly installed at the middle end of the rotating rod 20. A U-shaped rod 21 is fixedly connected to the upper end of the rotating rod 20. Both ends of the U-shaped rod 21 are movably connected to a connecting rod 18 via a bearing. A movable clamping plate 4 is movably connected to the surface of the connecting rod 18 via a bearing. Both ends of the top of the outer surface of the support platform 1 are fixedly connected to a U-shaped baffle 5.

[0025] In this technical solution, the support platform 1, U-shaped baffle 5, worm gear 2, worm wheel 19, rotating rod 20, U-shaped rod 21, connecting rod 18, and movable clamping plate 4 are used to clamp and fix the two sets of tungsten carbide reinforced steel matrix composite materials to be compared and tested, preventing the tungsten carbide reinforced steel matrix composite materials from shifting during subsequent testing. Furthermore, the rotating shaft 15, first bevel gear 14, second bevel gear 16, first rotating sleeve 6, first screw 7, lifting plate 9, pressure sensor 13, fixing frame 8, stepper motor 25, drive roller 26, and sanding belt 28 are used to simultaneously grind the surfaces of the two sets of tungsten carbide reinforced steel matrix composite materials. This facilitates comparison between the two sets of tungsten carbide reinforced steel matrix composite materials during wear testing, effectively improving the efficiency of wear comparison testing and greatly facilitating daily testing work.

[0026] It should be noted that the pressure sensor 13 and the stepper motor 25 are electrically connected to an external PLC controller so that personnel can observe the monitoring data of the pressure sensor 13 and control the stepper motor 25 through the PLC controller.

[0027] Example 2:

[0028] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2As shown, the right end of the support platform 1 is movably connected to a second rotating sleeve 11 via a bearing. The top of the second rotating sleeve 11 is threadedly connected to a second screw 10. The top of the second screw 10 is fixedly connected to the right end of the bottom of the lifting plate 9. A second synchronous pulley 24 is fixedly installed at the lower end of the second rotating sleeve 11. A first synchronous pulley 17 is fixedly installed at the lower end of the first rotating sleeve 6. A synchronous belt 23 is drivingly connected between the middle end of the first synchronous pulley 17 and the middle end of the second synchronous pulley 24.

[0029] In this technical solution, through the arrangement of the first synchronous pulley 17, the synchronous belt 23, the second synchronous pulley 24, the second rotating sleeve 11, and the second screw 10, the first rotating sleeve 6 can rotate while the second synchronous pulley 24 and the second rotating sleeve 11 are driven to rotate via the first synchronous pulley 17 and the synchronous belt 23. Since the first screw 7 and the second screw 10, and the first synchronous pulley 17 and the second synchronous pulley 24 have the same specifications, the first rotating sleeve 6 and the second rotating sleeve 11 can simultaneously drive the first screw 7 and the second screw 10 to move downward under the action of rotation, thereby effectively ensuring that the lifting plate 9 can move downward smoothly, avoiding the lifting plate 9 from tilting due to force, and ensuring that the test operation can be carried out normally.

[0030] Example 3:

[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a tension roller 27 is movably connected to the left end of the inner cavity of the fixed frame 8 via a bearing. The left end of the sanding belt 28 is driven to the surface of the tension roller 27. The back end of the drive roller 26 is movably connected to the right end of the inner cavity of the fixed frame 8 via a bearing. Guide slide rods 12 are slidably connected to both ends of the lifting plate 9. The bottom of the guide slide rods 12 is fixedly connected to the top of the fixed frame 8. Guide rods 3 are fixedly connected to both ends of the top of the support platform 1. The middle end of the movable clamping plate 4 is slidably connected to the surface of the guide rods 3. A rubber pad is fixedly connected to the upper end of the movable clamping plate 4. A support plate 22 is movably connected to the back end of the worm gear 2 via a bearing. The bottom of the support plate 22 is fixedly connected to the bottom of the inner cavity of the support platform 1. The first bevel gear 14 meshes with the second bevel gear 16, and the worm gear 2 meshes with the worm wheel 19.

[0032] In this technical solution, the tensioning roller 27 can be used to tension and guide the left end of the sand belt 28. The guide slide rod 12 is used to guide the fixed frame 8 and the lifting plate 9, preventing the fixed frame 8 from tilting due to force. The guide rod 3 is used to guide the moving clamp 4, preventing the moving clamp 4 from tilting due to force. The support plate 22 is used to support the back of the worm gear 2.

[0033] The working principle of this utility model is as follows: When it is necessary to conduct a comparative wear test on two sets of tungsten carbide reinforced steel matrix composites produced under different processes, the two sets of tungsten carbide reinforced steel matrix composites of the same specifications are placed on the top of the support platform 1 and inside the U-shaped retaining frame 5. The worm gear 2 is rotated, which drives the worm wheel 19, the rotating rod 20 and the U-shaped rod 21 to rotate. The rotation of the U-shaped rod 21 can push the moving clamp 4 to move through the connecting rod 18 until the moving clamp 4 can be tightly attached to the side of the tungsten carbide reinforced steel matrix composite, thereby clamping and fixing the two sets of tungsten carbide reinforced steel matrix composites to be compared and tested, and preventing the tungsten carbide reinforced steel matrix composites from shifting during the subsequent test. Then, the rotating shaft 15 and the first bevel gear 14 are rotated, which drives the second bevel gear 16 and the first rotating sleeve 6 to rotate. The rotation of the first rotating sleeve 6 drives the first screw 7, lifting plate 9, pressure sensor 13, fixed frame 8, stepper motor 25, drive roller 26, and sanding belt 28 to move downwards until the sanding belt 28 is in close contact with the top of the two sets of tungsten carbide reinforced steel matrix composite materials. At the same time, when the pressure data of the sanding belt 28 on the tungsten carbide reinforced steel matrix composite materials monitored by the pressure sensor 13 is required for composite testing, the stepper motor 25 is started to drive the drive roller 26 to rotate. The rotation of the drive roller 26 drives the sanding belt 28 to move, so that the sanding belt 28 can simultaneously perform grinding operations on the surfaces of the two sets of tungsten carbide reinforced steel matrix composite materials under the action of movement. This makes it convenient for personnel to compare the two sets of tungsten carbide reinforced steel matrix composite materials during wear testing, effectively improving the efficiency of wear comparison testing and bringing great convenience to personnel's daily testing work.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
