Description

Technical Field

[0001] This utility model relates to the field of research and development technology of novel diamond-based composite materials, specifically to a wear resistance testing device for diamond composite materials. Background Technology

[0002] Diamond composite materials are materials composed of diamond and other materials (such as cemented carbide, metals, ceramics, etc.). They possess the high hardness, high wear resistance, and high thermal conductivity of diamond, as well as the strength, impact toughness, and other excellent properties of the matrix material. Wear resistance testing equipment for diamond composite materials is an important tool for testing the performance of diamond composite material products.

[0003] In the prior art, patent CN209014419U discloses a wear resistance testing device for nanodiamond composite materials, including a testing box, four legs fixedly connected to the lower end of the testing box, two boxes with hinges symmetrically connected on the front side wall of the testing box, and a servo motor fixedly installed on the top wall of the testing box by a bracket. A collection device is fixedly installed on the side wall of the testing box, and a rotating shaft is vertically connected to the output end of the servo motor.

[0004] Although this wear resistance testing equipment for nanodiamond composite materials collects material waste in a closed space, some material waste still remains inside the testing chamber due to the fact that the collection unit is located on the side of the testing chamber and is guided by wind. This affects the accuracy of the material waste statistics and ultimately the wear resistance test results of the material. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a wear resistance testing device for diamond composite materials. The device uses two collection hoppers to form a small collection space, which facilitates the rapid collection of wear debris, greatly improving the accuracy of wear resistance testing of diamond composite materials and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wear resistance testing device for diamond composite materials, comprising a wear resistance testing frame, a horizontal plate fixedly connected to the lower end of the wear resistance testing frame, a testing chamber provided at the upper end of the horizontal plate, and a collection mechanism;

[0007] The collection mechanism includes a lower collection hopper, an upper collection hopper, guide columns, a sliding plate, an auxiliary plate, and a collection chamber. The lower collection hopper is fixedly connected to the inside of the wear resistance testing frame. A uniformly distributed filter screen is installed at the lower end of the lower collection hopper. Guide columns are fixedly connected to the four corners of the wear resistance testing frame. A sliding plate is slidably connected to the upper end of the four guide columns. The lower end of the sliding plate is fixedly connected to the upper end of the upper collection hopper through symmetrically distributed support columns. The lower end of the upper collection hopper is fitted with the upper end of the lower collection hopper. A uniformly distributed auxiliary plate is fixedly connected to the middle of the outer surface of the upper collection hopper. The end of the auxiliary plate away from the center of the wear resistance testing frame is slidably connected to the outer surface of the horizontally adjacent guide columns. A discharge pipe is fixedly connected to the lower end of the lower collection hopper. The outer surface of the discharge pipe is slidably connected to the inside of the collection chamber. The collection chamber is located inside the testing chamber. The upper and lower collection hoppers form a small collection space, which facilitates the rapid collection of wear debris and greatly improves the accuracy of wear resistance testing of diamond composite materials.

[0008] Furthermore, a controller is provided on the left end of the front surface of the wear-resistant testing frame. The input end of the controller is electrically connected to an external power supply to control various electrical appliances.

[0009] Furthermore, the collection mechanism also includes an electric push rod, which is symmetrically arranged at the upper end of the wear-resistant testing frame. The telescopic ends of the electric push rods are fixedly connected to the upper end of the sliding plate, and the input ends of the two electric push rods are electrically connected to the output end of the controller to provide guidance for the movement of the upper collection hopper.

[0010] Furthermore, a fixed chamber is fixedly connected inside the lower collecting hopper, and a sliding disc is slidably connected inside the fixed chamber. Evenly distributed sliding rods are slidably connected to the upper end of the fixed chamber. The lower ends of the four sliding rods are all fixedly connected to the upper end of the sliding disc, and pressure plates are fixedly connected to the upper ends of the sliding rods. An electric push rod II is provided on the top wall of the fixed chamber. The telescopic end of the electric push rod II is fixedly connected to the upper end of the sliding disc, and the input end of the electric push rod II is electrically connected to the output end of the controller to achieve stable clamping of the diamond composite material.

[0011] Furthermore, an electric push rod three is provided at the upper end of the sliding plate, and a motor compartment is slidably connected to the upper end of the upper collection hopper. The telescopic end of the electric push rod three is fixedly connected to the upper end of the motor compartment. A motor is provided on the bottom wall of the motor compartment, and a grinding wheel is fixedly connected to the lower end of the motor output shaft. Fans are provided at both the front and rear ends of the upper surface of the upper collection hopper. The input ends of the motor, the two fans, and the electric push rod three are all electrically connected to the output end of the controller to realize the grinding of diamond composite materials and provide driving force for the movement of diamond composite material waste.

[0012] Furthermore, a pressure sensor is installed on the bottom wall of the detection chamber. The pressure probe of the pressure sensor is installed in conjunction with the lower end of the collection chamber. The pressure sensor is bidirectionally electrically connected to the controller. By detecting the mass of diamond composite material waste, the wear resistance of the diamond composite material is calculated based on the wear time.

[0013] Furthermore, the lower end of the testing chamber is fixedly connected with evenly distributed guide rods, and the interior of the horizontal plate is provided with evenly distributed sliding openings.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This diamond composite material wear resistance testing equipment has the following advantages:

[0015] The upper collection hopper is moved downward by an electric push rod, so that the upper and lower collection hoppers form a small collection space. This avoids excessive splashing of the wear debris generated by the diamond composite material, and at the same time facilitates the rapid collection of the wear debris. This prevents too much diamond composite material debris from remaining in the collection chamber, which would affect the accuracy of the wear resistance test of the diamond composite material, and greatly improves the accuracy of the wear resistance test of the diamond composite material.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a wear resistance testing device for diamond composite materials, including a wear resistance testing frame 1, a horizontal plate 16 fixedly connected to the lower end of the wear resistance testing frame 1, a testing chamber 12 provided at the upper end of the horizontal plate 16, a controller 17 provided at the left end of the front surface of the wear resistance testing frame 1, the input end of the controller 17 being electrically connected to an external power supply, and also includes a collection mechanism 2.

[0022] Collection mechanism 2 includes a lower collection hopper 21, an upper collection hopper 22, guide columns 23, a sliding plate 24, an auxiliary plate 25, and a collection chamber 26. The lower collection hopper 21 is fixedly connected to the inside of the wear-resistant testing frame 1. A uniformly distributed filter screen 18 is provided at the lower end of the lower collection hopper 21. Guide columns 23 are fixedly connected to the four corners of the wear-resistant testing frame 1. A sliding plate 24 is slidably connected to the upper end of the four guide columns 23. The lower end of the sliding plate 24 is fixedly connected to the upper end of the upper collection hopper 22 through symmetrically distributed support columns. The lower end of the upper collection hopper 22 is fitted with the upper end of the lower collection hopper 21. The middle of the outer surface of the upper collection hopper 22... The auxiliary plate 25 is fixedly connected to the part, and the end of the auxiliary plate 25 away from the center of the wear-resistant test frame 1 is slidably connected to the outer surface of the horizontally adjacent guide column 23. The lower end of the lower collection hopper 21 is fixedly connected to the discharge pipe, and the outer surface of the discharge pipe is slidably connected to the inside of the collection bin 26. The collection bin 26 is located inside the test bin 12. The collection mechanism 2 also includes an electric push rod 27, which is symmetrically arranged on the upper end of the wear-resistant test frame 1. The telescopic ends of the electric push rod 27 are fixedly connected to the upper end of the sliding plate 24, and the input ends of the two electric push rods 27 are electrically connected to the output end of the controller 17.

[0023] The lower collection hopper 21 has a fixed chamber 3 internally, a sliding disc 4 internally, and a uniformly distributed sliding rod 5 slidably connected to the upper end of the fixed chamber 3. The lower ends of the four sliding rods 5 are fixedly connected to the upper ends of the sliding disc 4, and pressure plates are fixedly connected to the upper ends of the sliding rods 5. An electric push rod 6 is installed on the top wall of the fixed chamber 3. The telescopic end of the electric push rod 6 is fixedly connected to the upper end of the sliding disc 4, and the input end of the electric push rod 6 is electrically connected to the output end of the controller 17. The diamond composite material to be tested is placed on the upper end of the fixed chamber 3, and then the controller 17 drives the electric push rod 6. The telescopic end of the electric push rod 6 extends and pushes the sliding disc 4 downward. The downward movement of the sliding disc 4 causes the four sliding rods 5 to move downward. The downward movement of the sliding rods 5 causes the vertically adjacent pressure plates to move downward. The pressure plates contact the diamond composite material, thereby clamping and fixing the diamond composite material.

[0024] Wherein: an electric push rod 11 is provided at the upper end of the sliding plate 24; a motor compartment 7 is slidably connected to the upper end of the upper collecting hopper 22; the telescopic end of the electric push rod 11 is fixedly connected to the upper end of the motor compartment 7; a motor 8 is provided on the bottom wall of the motor compartment 7; a grinding wheel 9 is fixedly connected to the lower end of the output shaft of the motor 8; fans 10 are provided at both the front and rear ends of the upper surface of the upper collecting hopper 22; the input ends of the motor 8, the two fans 10, and the electric push rod 11 are all electrically connected to the output end of the controller 17; the electric push rod... When the electric push rod 27 operates, the telescopic end of the electric push rod 27 extends, pushing the sliding plate 24 downward. Guided by the guide post 23, the sliding plate 24 moves downward, causing the upper collecting hopper 22 to move downward. Simultaneously, the auxiliary plates 25 all move downward on the outer surface of their corresponding guide posts 23, further ensuring the stability of the upper collecting hopper 22's sliding. When the lower end of the upper collecting hopper 22 is inserted into the slot at the upper end of the upper collecting hopper 21, the controller 17 shuts off the electric push rod 27 and activates the electric push rod 11. Okay, the telescopic end of the electric push rod 11 extends and pushes the motor compartment 7 to move down. The movement of the motor compartment 7 drives the grinding wheel 9 to move down. When the grinding wheel 9 comes into contact with the diamond composite material, the controller 17 shuts off the electric push rod 11 and starts the motor 8. The output shaft of the motor 8 rotates and drives the grinding wheel 9 to rotate. The rotating grinding wheel 9 comes into contact with the diamond composite material, causing wear on the diamond composite material. At the same time, the controller 17 starts the fan 10. The fan 10 blows the diamond composite material waste downward in the small collection space formed by the lower collection hopper 21 and the upper collection hopper 22, so that the diamond composite material waste is collected inside the discharge pipe. At the same time, the air is discharged through the filter screen 18. Under the action of the filter screen 18, the diamond composite material waste is retained inside the lower collection hopper 21. Then the diamond composite material waste falls into the collection compartment 26 through the discharge pipe. When the grinding wheel 9 has worked for a specified time, the controller 17 shuts off the motor 8 and the fan 10.

[0025] The bottom wall of the detection chamber 12 is equipped with a pressure sensor 13. The pressure probe of the pressure sensor 13 is fitted to the lower end of the collection chamber 26. The pressure sensor 13 is bidirectionally electrically connected to the controller 17. The lower end of the detection chamber 12 is fixedly connected with evenly distributed guide rods 15. The interior of the horizontal plate 16 is provided with evenly distributed sliding slots. The guide rods 15 are all slidably connected to the vertically adjacent sliding slots. The lower end of the horizontal plate 16 is equipped with an electric push rod 14. The telescopic end of the electric push rod 14 is fixedly connected to the lower end of the detection chamber 12. The input end of the electric push rod 14 is electrically connected to the output end of the controller 17. The controller 17 enables the operation of the pressure sensor 13. The pressure sensor 13 controls the pressure of the diamond inside the collection chamber 26. The weight of the diamond composite material waste is calculated and transmitted to the signal receiving end of the controller 17. The controller 17 calculates the wear amount of the diamond composite material per unit time based on the data, and finally obtains the wear resistance performance of the diamond composite material. Then, the controller 17 activates the electric push rod 14. The telescopic end of the electric push rod 14 retracts, causing the detection chamber 12 to move down, which in turn causes the collection chamber 26 to move down. At the same time, the guide rods 15 slide inside the corresponding sliding ports to ensure the stability of the downward movement of the collection chamber 26. When the collection chamber 26 stops contacting the discharge pipe, the collection chamber 26 is removed, and the diamond composite material waste inside the collection chamber 26 is cleaned, ready for the next wear resistance test of the material.

[0026] The working principle of the wear resistance testing device for diamond composite materials provided by this utility model is as follows: During operation, the operator first stably places the wear resistance testing frame 1, the fixed chamber 3, and other mechanisms in a horizontal working area. After stable placement, the operator places the diamond composite material to be tested on the upper end of the fixed chamber 3. Then, the operator uses the controller 17 to operate the electric push rod 6. The extension end of the electric push rod 6 extends, pushing the sliding disk 4 downwards. The downward movement of the sliding disk 4 causes the four sliding rods 5 to move downwards. The downward movement of the sliding rods 5 causes the vertically adjacent pressure plates to move downwards. The pressure plates contact the diamond composite material, achieving clamping and fixing of the diamond composite material. After stable clamping, the operator uses the controller 17 to close the electric push rod 6 and operate the electric push rod 27. The extension end of the push rod 27 pushes the sliding plate 24 downward. Guided by the guide post 23, the sliding plate 24 moves downward, causing the upper collecting hopper 22 to move downward. Simultaneously, the auxiliary plates 25 move downward on the outer surface of their corresponding guide posts 23, further ensuring the stability of the upper collecting hopper 22's sliding motion. When the lower end of the upper collecting hopper 22 is inserted into the slot at the upper end of the upper collecting hopper 21, the controller 17 shuts off the electric push rod 27 and activates the electric push rod 11. The extension end of the electric push rod 11 pushes the motor housing 7 downward, causing the grinding wheel 9 to move downward. When the grinding wheel 9 comes into contact with the diamond composite material, the controller 17 shuts off the electric push rod 11 and activates the motor 8, causing the output shaft of the motor 8 to rotate. The grinding wheel 9 rotates, contacting the diamond composite material and causing wear. Simultaneously, the controller 17 activates the fan 10, which blows diamond composite material debris downwards within the small collection space formed by the lower and upper collection hoppers 21 and 22. This ensures the debris is collected inside the discharge pipe. The airflow passes through the filter screen 18, which retains the debris inside the lower collection hopper 21. The debris then falls through the discharge pipe into the collection chamber 26. When the grinding wheel 9 has worked for a specified time, the controller 17 shuts off the motor 8 and fan 10, and activates the pressure sensor 13. Sensor 13 calculates the weight of diamond composite material waste inside collection chamber 26 and transmits the data to the signal receiving end of controller 17. Controller 17 calculates the wear amount of diamond composite material per unit time based on the data, and finally obtains the wear resistance performance of diamond composite material. Then, controller 17 activates electric push rod 14. The telescopic end of electric push rod 14 retracts, causing detection chamber 12 to move down, which in turn causes collection chamber 26 to move down. At the same time, guide rods 15 slide inside their corresponding sliding ports to ensure the stability of collection chamber 26 as it moves down. When collection chamber 26 stops contacting the discharge pipe, personnel remove collection chamber 26 and clean the diamond composite material waste inside, ready for the next wear resistance test of the material.

[0027] It is worth noting that the controller 17 disclosed in the above embodiments controls the operation of electric push rod 1 27, electric push rod 2 6, motor 8, fan 10, electric push rod 3 11, pressure sensor 13 and electric push rod 4 14 using methods commonly used in the prior art.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
