Description

Technical Field

[0001] This invention relates to the field of polymer materials technology, and more specifically to a device for testing the wear resistance of polymer materials. Background Technology

[0002] With the continuous development of science and technology, materials science has made great progress, and various new materials are emerging one after another and being applied to more and more fields. Polymer materials are one of the most representative ones, with a wide range of applications and increasing importance. During the production process, polymer materials need to be tested for wear resistance to check their wear resistance performance.

[0003] When testing the wear resistance of polymer materials, it is necessary to use a grinding device to repeatedly grind the same position of the polymer material to test its wear resistance. However, existing polymer materials have poor fixation during grinding, and the polymer material will be displaced due to the force of the grinding device, which reduces the accuracy of the test. Therefore, we propose a polymer material wear resistance testing device. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a polymer material abrasion resistance testing device, including a base plate, a support leg fixedly connected to the bottom of the base plate, a fixing frame fixedly connected to the top of the base plate, a limit frame fixedly connected to the top of the fixing frame, an electric push rod fixedly connected to the top of the inner wall of the limit frame, a lifting plate fixedly connected to the bottom of the electric push rod, a motor fixedly connected to the top of the lifting plate, a rotating rod fixedly connected to the bottom of the motor, a grinding frame fixedly connected to the top of the base plate, a turntable fixedly connected to the bottom of the rotating rod, a threaded rod fixedly connected to the bottom of the base plate, a storage rack threadedly connected to the bottom of the threaded rod, a filter screen fixedly connected to the inner wall of the storage rack, a hexagonal rod inserted into the top of the base plate, and a discharge valve provided at the bottom of the storage rack, and further comprising:

[0005] The clamping component includes a rotating ring, which is rotatably connected to the bottom of the turntable via a bearing. A telescopic rod is fixedly connected to the bottom of the turntable. A limiting frame is fixedly connected to the top of a fixed frame. The fixed frame is located at the top rear end of the base plate. The end of the limiting frame away from the fixed frame extends to the top of the grinding frame. Two electric push rods are installed inside the limiting frame. A lifting plate is fixedly connected to the telescopic end of the electric push rod, allowing the lifting plate to push the motor upward via the electric push rod. The rotating rod extends through the limiting frame to the top of the turntable. A hexagonal rod is slidably connected to the inner wall of the base plate. A grinding block is fixedly connected to the bottom of the telescopic rod. A support frame is fixedly connected to the bottom of the inner wall of the grinding frame. A clamping block is installed at the lower end of the rotating ring.

[0006] The extrusion component includes a ring frame, which is rotatably connected to the bottom of the turntable via a bearing. A sliding groove plate is fixedly connected to the bottom of the ring frame, and a positioning ring is rotatably connected to the top of the grinding block via a bearing.

[0007] A flushing component, comprising a water tank, which is fixedly connected to a base plate via an extension rod. A sealing component is provided at the inner ring of the water tank. A circular tube is connected to the end of the sealing component away from the water tank. A circular annular tube is connected to the end of the circular tube away from the sealing component. A right-angle tube is connected to the inner ring of the circular annular tube. A circular hole ring is connected to the bottom of the right-angle tube.

[0008] Furthermore, the circular ring is rotatably connected to the turntable via a bearing, the bottom of the circular ring is connected to the interior of the grinding frame via a circular hole, and the top of the water tank is connected to a water inlet pipe.

[0009] Furthermore, the bottom of the rotating rod passes through the limiting frame and extends to the bottom outer end of the limiting frame. The turntable contacts the inner wall of the grinding frame. A drainage hole is opened at the bottom of the inner wall of the grinding frame. The grinding frame communicates with the interior of the storage rack through the drainage hole. The top of the support frame contacts the bottom of the grinding block.

The grinding block is fixedly connected to the bottom of the turntable via a telescopic rod. After the polymer material is placed inside the grinding frame, the support frame contacts the bottom center of the polymer material. When the grinding block grinds the polymer material, the support frame supports and limits the polymer material to prevent it from sinking during grinding, which would reduce the grinding efficiency of the grinding block and reduce the accuracy of the wear resistance test. The bottom of the elastic rod is fixedly connected to the top of the clamping block, and an anti-slip pad is fixedly connected to the bottom of the clamping block.

[0011] The number of clamping blocks is set to six.

A slider is slidably connected to the inner wall of the slide plate. The hinge frame and the slider are hinged together by a spring rod. The ring frame is rotatably connected to the bottom of the turntable. When the turntable rotates, the slide plate is positioned inside the grinding frame by the ring frame and will not rotate synchronously with the turntable, thus avoiding tilting of the polymer material during grinding, which would reduce the accuracy of the detection. The slider and the clamping block are hinged together by a diagonal rod.

[0014] The number of sliding plates is set to six, and the slider and the hinge frame are hinged by two elastic rods.

[0015] Furthermore, the slider is located at one end of the slide plate near the telescopic rod, the ring frame is located at the top center of the slide plate, and the positioning ring is located on the outer surface of the telescopic rod.

[0016] Furthermore, the flushing component includes an air cylinder rod, the bottom of which is fixedly connected to the top of a hexagonal rod. An air cushion is provided inside the air cylinder rod, and a pull rod is fixedly connected to the top of the air cushion. The pull rod and the air cylinder rod are hinged together by an elastic triangular frame. An arc plate is fixedly connected to the center end of the elastic triangular frame. The turntable is rotatably connected to a water tank through a circular hole ring. The water tank is connected to a circular ring pipe through a circular pipe. Water inside the water tank enters the interior of the circular ring pipe through the circular pipe and then enters the interior of the grinding frame through the circular hole ring to cool the polymer material. The top of the air cylinder rod is connected to the top of the water tank through a bent pipe. A drive ring is fixedly connected to the top of the turntable, and a semi-circular frame is fixedly connected to the surface of the drive ring.

[0017] The elastic triangular frame is located at the outer end of the air pump rod, and the bottom of the air pump rod is connected to a one-way valve. The number of air pump rods is set to four.

[0018] Furthermore, the end of the arc plate away from the elastic tripod contacts the surface of the drive ring, the inner wall of the drive ring contacts the surface of the grinding frame, and the semi-circular frame and the arc plate are horizontally arranged.

[0019] Furthermore, the sealing component includes a fixing block and a sealing ring. The fixing block is fixedly connected to the inner wall of the water tank, the sealing ring is fixedly connected to the inner wall of the water tank, a groove ring is fixedly connected to the inner wall of the sealing ring, a sealing gasket is fixedly connected to the inner wall of the groove ring, a blocking plate is provided inside the sealing ring, and a positioning slide is fixedly connected to the inner wall of the sealing ring.

[0020] The blocking plate is fixedly connected to the positioning slide by a spring, and the blocking plate is slidably connected to the inner wall of the positioning slide. The water tank and the round pipe are connected by a fixing block. The sealing ring is connected to the fixing block, and the blocking plate is in contact with the surface of the sealing gasket.

[0021] The beneficial effects of this invention are as follows:

[0022] This invention features a clamping component inside the grinding frame. After the polymer material is placed inside the grinding frame, it contacts and is supported by the clamping component. The turntable moves into the grinding frame via an electric push rod, bringing the clamping component into contact with the surface of the polymer material. The downward movement of the electric push rod further compresses and fixes the polymer material. The compression component further increases the clamping force by compressing the clamping component. A flushing component is located above the grinding frame to flush the polymer material, preventing it from overheating during grinding. A sealing component is located inside the water tank to seal it. When the grinding block stops polishing the polymer material, the sealing component blocks the water tank, preventing water waste. The water used to flush the polymer material enters the storage rack through a leak and is filtered through a filter to remove impurities, improving the reuse rate.

[0023] In this invention, after the polymer material is placed inside the grinding frame, the polymer material will come into contact with the top of the contact frame. The contact frame increases the friction between itself and the polymer material through a rubber pad. The rotating ring pushes the clamping block downward by the downward movement of the turntable. The clamping block contacts the top surface of the polymer material through an anti-slip pad. The pressure of the downward movement of the electric push rod is used to clamp and fix the polymer material. The clamping block uses the elastic force of the elastic rod to improve the stability of clamping the polymer material.

[0024] When the turntable of this invention moves into the interior of the grinding frame, the grinding block contacts the top of the support frame. After the grinding block contacts the top of the support frame, it squeezes the telescopic rod to retract. The grinding block pushes the elastic rod upward through the hinge frame. The elastic rod pushes the slider to move inside the slide plate. The slider squeezes the clamping block downward through the inclined rod, further increasing the clamping force of the clamping block on the polymer material and improving the stability of the polymer material during grinding.

[0025] In this invention, the semi-circular frame compresses the arc plate through the rotation of the drive ring. The elastic triangle deforms due to the compression of the arc plate, which in turn pushes the pull rod upward. The air cushion reciprocates inside the air cylinder rod due to the deformation of the elastic triangle. The air cylinder rod transmits gas to the inside of the water tank, and the gas pushes the water inside the water tank into the inside of the circular ring, cooling the polymer material and the grinding block. The water impacts the polymer material, preventing grinding debris from adhering to the surface of the polymer material, thus reducing grinding efficiency and detection efficiency.

[0026] After the air pressure enters the water tank, the air pressure inside the water tank increases, and the gas pushes the blocking plate and the sealing gasket to separate. This allows the water inside the water tank to enter the inside of the circular tube through the sealing ring. When the grinding block stops rotating, the air pressure inside the water tank decreases, and the blocking plate uses the elasticity of the spring to contact the sealing gasket and block the water tank, thus avoiding water waste.

The invention includes a clamping component 16 inside the grinding frame 11. After the polymer material is placed inside the grinding frame 11, the polymer material contacts and is supported by the clamping component 16. The turntable 12 is moved by the electric push rod 5. After moving into the interior of the grinding frame 11, the clamping component 16 contacts the surface of the polymer material, and the polymer material is squeezed and fixed by the downward movement of the electric push rod 5. The squeezing component 25 squeezes the clamping component 16 by the downward movement of the electric push rod 5, further increasing the clamping force of the clamping component 16. A flushing component 7 is provided above the grinding frame 11 to flush the polymer material and prevent the polymer material from getting too hot during grinding. A sealing component 45 is provided inside the water tank 40 to seal the water tank 40. When the grinding block 18 stops grinding the polymer material, the sealing component 45 will block the water tank 40 to avoid wasting water. The water after flushing the polymer material enters the interior of the storage rack 15 through the leakage hole and is filtered by the filter screen 14 to improve the reuse rate.

A sealing component 45 is provided on the inner ring of the water tank 40. A round pipe 41 is connected to the end of the sealing component 45 away from the water tank 40. A circular annular pipe 42 is connected to the end of the round pipe 41 away from the sealing component 45. A right-angle pipe 46 is connected to the inner ring of the circular annular pipe 42.

[0042] The circular ring 43 is rotatably connected to the turntable 12 via a bearing. The bottom of the circular ring 43 is connected to the interior of the grinding frame 11 through a circular hole. The top of the water tank 40 is connected to a water inlet pipe.

[0043] The bottom of the rotating rod 9 passes through the limiting frame 4 and extends to the bottom outer end of the limiting frame 4. The turntable 12 contacts the inner wall of the grinding frame 11. A hole is opened at the bottom of the inner wall of the grinding frame 11. The grinding frame 11 communicates with the interior of the storage rack 15 through the hole. The top of the support frame 19 contacts the bottom of the grinding block 18.

[0044] The clamping component 16 includes a contact frame 23, which is fixedly connected to the bottom of the inner wall of the grinding frame 11. A rubber pad 22 is fixedly connected to the top of the contact frame 23. An elastic rod 26 is fixedly connected to the bottom of the rotating ring 20. The bottom of the elastic rod 26 is fixedly connected to the top of the clamping block 24. After the polymer material is placed inside the grinding frame 11, the polymer material will contact the top of the contact frame 23. The contact frame 23 increases the friction between itself and the polymer material through the rubber pad 22. The rotating ring 20 pushes the clamping block 24 downward by the downward movement of the turntable 12. The clamping block 24 contacts the top surface of the polymer material through the anti-slip pad 21. The pressure of the downward movement of the electric push rod 5 is used to clamp and fix the polymer material. The clamping block 24 uses the elastic force of the elastic rod 26 to improve the stability of clamping the polymer material. An anti-slip pad 21 is fixedly connected to the bottom of the clamping block 24.

[0045] The number of clamping blocks 24 is set to six.

[0046] There are two contact frames 23, both of which are located inside the grinding frame 11. The two grinding frames 11 are of different sizes, and the clamping block 24 is located above the contact frames 23.

[0047] The extrusion component 25 includes a hinge frame 32, which is fixedly connected to the bottom of the positioning ring 33. A slider 34 is slidably connected to the inner wall of the slide plate 31. When the turntable 12 moves into the interior of the grinding frame 11, the grinding block 18 contacts the top of the support frame 19. After the grinding block 18 contacts the top of the support frame 19, the extrusion telescopic rod 17 is retracted. The grinding block 18 pushes the elastic rod 36 upward through the hinge frame 32. The elastic rod 36 pushes the slider 34 to move inside the slide plate 31. The slider 34 squeezes the clamping block 24 downward through the inclined rod 35, further increasing the clamping force of the clamping block 24 on the polymer material and improving the stability of the polymer material during grinding. The hinge frame 32 and the slider 34 are hinged through the elastic rod 36, and the slider 34 and the clamping block 24 are hinged through the inclined rod 35.

[0050] The flushing component 7 includes an air cylinder rod 48, the bottom of which is fixedly connected to the top of a hexagonal rod 8. An air cushion 53 is installed inside the air cylinder rod 48, and a pull rod 52 is fixedly connected to the top of the air cushion 53. The pull rod 52 and the air cylinder rod 48 are hinged together by an elastic triangular frame 49. An arc plate 51 is fixedly connected to the center end of the elastic triangular frame 49. The air cylinder rod 48 is connected to the top of the water tank 40 via a bent pipe 47. In this invention, the semi-circular frame 54, through the rotation of the drive ring 50, presses against the arc plate 51. The elastic triangular frame 49 deforms due to the pressure from the arc plate 51, and thus... Push the lever 52 upward, and the air cushion 53 moves back and forth inside the air cylinder rod 48 through the deformation of the elastic triangular frame 49. The air cylinder rod 48 transmits gas to the inside of the water tank 40. The gas pushes the water inside the water tank 40 into the inside of the circular ring 43 to cool the polymer material and the grinding block 18. The water impacts the polymer material to prevent the grinding debris from adhering to the surface of the polymer material, which would reduce the grinding efficiency and the detection efficiency.

[0053] Example 2

[0054] Distinguishing features from Example 1;

[0055] like Figure 8 As shown: The sealing component 45 includes a fixing block 60 and a sealing ring 61. The fixing block 60 is fixedly connected to the inner wall of the water tank 40, and the sealing ring 61 is fixedly connected to the inner wall of the water tank 40. A groove ring 62 is fixedly connected to the inner wall of the sealing ring 61, and a sealing gasket 64 is fixedly connected to the inner wall of the groove ring 62. A blocking plate 63 is provided inside the sealing ring 61. After the air pressure of the present invention enters the interior of the water tank 40, the air pressure inside the water tank 40 increases, and the gas will push the blocking plate 63 to separate from the sealing gasket 64, so that the water inside the water tank 40 can enter the interior of the round tube 41 through the sealing ring 61. When the grinding block 18 stops rotating, the air pressure inside the water tank 40 decreases, and the blocking plate 63 uses the elasticity of the spring 65 to contact the sealing gasket 64 to block the water tank 40, thus avoiding the waste of water. A positioning slide 66 is fixedly connected to the inner wall of the sealing ring 61.

[0056] The blocking plate 63 is fixedly connected to the positioning slide 66 via the spring 65. The blocking plate 63 is slidably connected to the inner wall of the positioning slide 66. The water tank 40 and the round pipe 41 are connected via the fixing block 60. The sealing ring 61 is connected to the fixing block 60. The blocking plate 63 is in contact with the surface of the sealing gasket 64.

[0057] One specific application of this embodiment is as follows: After the polymer material is placed inside the grinding frame 11, the polymer material will contact the top of the contact frame 23. The contact frame 23 increases the friction between itself and the polymer material through the rubber pad 22. The rotating ring 20 pushes the clamping block 24 downward through the downward movement of the turntable 12. The clamping block 24 contacts the top surface of the polymer material through the anti-slip pad 21. The pressure of the downward movement of the electric push rod 5 is used to clamp and fix the polymer material. The clamping block 24 uses the elastic force of the elastic rod 26 to improve the clamping force on the polymer material. To ensure the stability of the molecular material clamping, when the turntable 12 moves into the grinding frame 11, the grinding block 18 contacts the top of the support frame 19. After contact, the grinding block 18 compresses the telescopic rod 17 to retract. The grinding block 18 pushes the elastic rod 36 upward through the hinge frame 32. The elastic rod 36 pushes the slider 34 to move inside the slide plate 31. The slider 34 compresses the clamping block 24 downward through the inclined rod 35, further increasing the clamping force of the clamping block 24 on the polymer material and improving the stability of the polymer material during grinding. To ensure stability, the semi-circular frame 54, through the rotation of the drive ring 50, compresses the arc plate 51. The elastic triangular frame 49 deforms due to the compression of the arc plate 51, which in turn pushes the pull rod 52 upward. The air cushion 53 reciprocates inside the air cylinder rod 48 due to the deformation of the elastic triangular frame 49. The air cylinder rod 48 transmits gas to the inside of the water tank 40, pushing the water inside the water tank 40 into the circular ring 43, cooling the polymer material and the grinding block 18. The water also washes the polymer material. To prevent grinding debris from adhering to the surface of the polymer material, which would reduce grinding efficiency and thus testing efficiency, the gas pressure enters the water tank 40. As the gas pressure inside the water tank 40 increases, it pushes the blocking plate 63 and the sealing gasket 64 to separate, allowing water inside the water tank 40 to enter the round tube 41 through the sealing ring 61. When the grinding block 18 stops rotating, the gas pressure inside the water tank 40 decreases, and the blocking plate 63 uses the elasticity of the spring 65 to contact the sealing gasket 64 to block the water tank 40, thus preventing water waste.
