Description

Technical Field

[0001] This invention relates to the field of testing technology, and in particular to a device and method for testing the heat resistance and insulation performance of diamond composite sheets. Background Technology

[0002] Diamond composite sheets are superhard materials composed of diamond layers and cemented carbide matrix. They are widely used in drilling and cutting tools. In actual working conditions, they need to withstand the high temperatures generated by intense friction. Therefore, evaluating their "heat resistance insulation performance" to prevent heat from being transferred to the interior is crucial to tool life. Thus, it is necessary to test the heat resistance insulation performance of diamond composite sheets.

[0003] Currently, existing heat insulation performance testing devices typically place the sample on a hollow heating platform, heat its surface with a heat source, and measure its temperature gradient to evaluate the heat insulation performance. However, after high-temperature testing (especially long-term or cyclic testing), the contact interface between the sample and the platform often forms microscopic adhesion due to local sintering, oxidation, or diffusion of the material, making it difficult to remove the sample smoothly. Therefore, this application proposes a heat insulation performance testing device and method for diamond composite sheets. Summary of the Invention

[0004] The purpose of this invention is to address the problem of high-temperature adhesion of samples and difficulty in removal in the prior art, and to propose a device and method for testing the heat resistance and insulation performance of diamond composite sheets.

The turntable has two sets of slots inside, and a temperature measuring station for placing a diamond composite sheet is fixed inside each of the two sets of slots. A motor for driving the turntable to rotate is installed inside the frame. The ejection mechanism, connected to the turntable, is used to eject the diamond composite sheet that is adhered to the temperature measuring stage. The cooling mechanism includes a cooler, a transmission pipe, a metal pipe, and a nozzle. The cooler is installed inside the frame, the transmission pipe is fixedly connected to the output end of the cooler, the metal pipe is connected to the transmission pipe, and the nozzle is connected to the metal pipe. A synchronization mechanism for driving the nozzle to continuously cool the moving diamond composite sheet includes an actuation component and a reset component, wherein: The actuation component is used to drive the nozzle to move along with the diamond when the diamond composite sheet arrives directly below the nozzle, and the reset component is used to drive the nozzle to reset.

[0006] Optionally, the ejection mechanism includes a ejector rod, a top plate, a side rod, and a guide block. The two ends of the ejector rod are slidably connected to the inside of the temperature measuring table and the turntable, respectively. The top plate is fixedly connected to the ejector rod, the side rod is fixedly connected to the outside of the top plate, and the guide block is fixedly connected to the top of the fixed platform.

[0007] Optionally, the execution component includes a trapezoidal block, a connecting block, two sets of arc-shaped guide rods, a fixing frame, an arc-shaped baffle, and a connecting frame. The trapezoidal block is slidably connected to the inside of the connecting block. Both sets of arc-shaped guide rods slide through the connecting block. The fixing frame is fixed to the top of the frame, and both ends of the arc-shaped guide rods are fixed to the inner wall of the fixing frame. The arc-shaped baffle is fixed to the outer side of the fixing frame, and the arc-shaped baffle is attached to the end of the trapezoidal block away from the nozzle. The connecting frame is fixed to the top of the connecting block, and the connecting frame is fixed to the outer side of the metal pipe.

[0008] Optionally, the reset mechanism includes a first spring, a connecting plate, a limiting rod, a support plate, and a second spring. The first spring is fixedly connected between the fixed frame and the connecting block. The connecting plate is fixedly connected to the trapezoidal block. The limiting rod is fixedly connected to the outer side of the connecting block and slides through the connecting plate. The support plate is fixedly connected to the end of the limiting rod away from the connecting plate. The second spring is fixedly connected between the support plate and the connecting plate.

[0009] Optionally, the elastic potential energy of the second spring is less than that of the first spring.

[0010] Optionally, the top of the arc-shaped baffle is provided with a slot, and an extension plate is embedded inside the slot.

[0011] Optionally, a spring three is sleeved on the outer side of the top rod, and the spring three is fixed between the top plate and the turntable.

[0012] Optionally, a connecting roller is rotatably connected to the outer side of the side rod.

[0013] Optionally, the top of the guide block may have multiple sets of vibration grooves.

[0014] Secondly, the present invention provides a method for testing the heat resistance and insulation performance of diamond composite sheets, applied to the heat resistance and insulation performance testing device for diamond composite sheets described in the first aspect, the method comprising the following steps: S1. Sample loading and heating test: The robotic arm places the sample on the temperature measuring platform, and the motor drives the turntable to rotate it above the high-temperature welding gun for heating. At the same time, the high-temperature tester tests the heat resistance and insulation performance of the sample. S2. Ejection and separation: After the test, the turntable continues to rotate. The side rod contacts the inclined surface of the guide block and rises. The top plate pushes the top rod upward to separate the sample from the temperature measuring table. The connecting roller on the side rod rolls along the vibration groove, causing the top rod to generate micro-vibration to assist in separation. S3. Following the cooling process, after the sample is moved to the bottom of the nozzle, the cold air from the air cooler blows cold air through the nozzle to cool it down. At the same time, the rotating side rod pushes the trapezoidal block, causing the connecting block to slide along the arc-shaped guide rod. The connecting frame drives the nozzle to move synchronously to achieve continuous cooling. S4. Reset and Material Retrieval: After the side rod passes the trapezoidal block, springs one and two release their elastic force, pulling the connecting block and pushing the trapezoidal block to reset respectively. The nozzle returns to its initial position, and the cooled sample is sent to the robot arm to be picked up and removed, completing the cycle.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention uses an ejection mechanism to automatically separate the sample from the temperature measuring platform after testing, effectively overcoming the problem of material handling caused by high-temperature adhesion. Furthermore, a cooling mechanism is used to rapidly cool the ejected high-temperature sample to a safe temperature, thus facilitating subsequent gripping and transfer by the robotic arm. This design improves the reliability of sampling and operational safety, and realizes automation and efficiency in the testing process.

[0016] Furthermore, the actuator can drive the nozzle to move synchronously with the rotating sample, achieving continuous and uniform cooling and ensuring sufficient cooling; the reset component can automatically reset the nozzle after a single cooling cycle, thus ensuring the continuity of the cooling process and the reliability of the automated cyclic operation of the equipment.

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-4As shown, this invention proposes a testing device for the heat resistance and insulation performance of diamond composite sheets, comprising a frame 1. A robotic arm 2 for loading and unloading and a high-temperature testing instrument 4 for testing diamond composite sheets are respectively mounted on the top of the frame 1. The frame 1 supports the robotic arm 2 and the high-temperature testing instrument 4. The robotic arm 2, as a mature existing technology, can grasp the diamond composite sheets, while the high-temperature testing instrument 4 can measure the temperature of the heated diamond composite sheets to determine their heat resistance and insulation performance. It should be noted that in this embodiment, the high-temperature testing instrument 4 relies on photoelectric detection elements such as infrared sensors to receive the thermal radiation energy emitted by the tested object and convert it into an electrical signal. The surface temperature of the object is calculated according to the law of thermal radiation, thus achieving non-contact temperature measurement. A high-temperature welding torch 3 is mounted on the top of the inner wall of the frame 1. The high-temperature welding torch 3, as a mature existing technology, can be used to rapidly heat the surface of the diamond composite sheets. The testing device also includes at least one solid... A fixed platform 5 is attached inside the frame 1. A turntable 6 is rotatably connected inside the fixed platform 5. The turntable 6 can rotate along the inside of the fixed platform 5. Two sets of slots 7 are opened inside the turntable 6. Temperature measuring platforms 8 for placing diamond composite sheets are fixed inside the two sets of slots 7. When heating and testing the diamond composite sheet, the diamond composite sheet is first picked up by the robot arm 2 and placed on the top of the temperature measuring platform 8. The frame 1 is equipped with a motor 9 for driving the turntable 6 to rotate. At this time, the motor 9 starts and drives the turntable 6 to rotate. When the turntable 6 rotates, it will move the diamond composite sheet located on the top of the temperature measuring platform 8. When the diamond composite sheet moves to the direct below the high temperature tester 4, the motor 9 stops and then the high temperature welding gun 3 is started. The high temperature welding gun 3 heats the surface of the diamond composite sheet. As the temperature of the diamond composite sheet rises, the high temperature tester 4 can test the heat resistance and insulation performance of the diamond composite sheet in real time.

[0023] As one implementation method, such as Figures 2-8As shown, the testing device also includes an ejection mechanism and a cooling mechanism. The ejection mechanism is connected to the turntable 6 and is used to eject the diamond composite sheet that is adhered to the temperature measuring platform 8. Due to the prolonged heating of the diamond composite sheet by the high-temperature welding torch 3, the contact interface between the sample (referring to the diamond composite sheet in this embodiment) and the temperature measuring platform 8 often forms microscopic adhesion due to local sintering, oxidation, or diffusion of the material, making it difficult to remove the sample smoothly. In this embodiment, after the test is completed, the turntable 6 will drive the ejection mechanism to run synchronously when rotating. When the turntable 6 rotates to a certain number of revolutions, the ejection mechanism will apply an upward thrust to the bottom of the sample, causing the sample to detach from the adhesion to the temperature measuring platform 8. The cooling mechanism includes a cooler 10, a transmission pipe 11, a metal pipe 12, and a nozzle 13. The cooler 10 is installed inside the frame 1, and the transmission pipe 12... The nozzle 11 is fixedly connected to the output end of the air cooler 10. The air cooler 10, as a mature existing technology, can transmit cold air to the inside of the transmission pipe 11. The metal pipe 12 is connected to the transmission pipe 11, and the transmission pipe 11 then transmits the cold air to the inside of the metal pipe 12. The nozzle 13 is connected to the metal pipe 12, and finally the cold air is blown out through the nozzle 13. When the sample arrives below the nozzle 13, the nozzle 13 can cool down the high-temperature sample, avoiding the situation where the sample surface temperature is too high and accidentally injures the operator. Subsequently, after the tested sample arrives at the control range of the robot 2, the robot 2 can easily grasp the sample, effectively avoiding the problem of sticking and being difficult to remove. At this time, the cold air sprayed by the nozzle 13 has reached a safe temperature, so even if the operator touches it accidentally, it will not cause any threat.

[0024] Furthermore, such as Figure 8 , Figure 9 and Figure 10 As shown, the testing device also includes a synchronization mechanism for driving the nozzle 13 to continuously cool the moving diamond composite sheet. This mechanism includes an execution component and a reset component. The execution component drives the nozzle 13 to move along with the diamond when the diamond composite sheet reaches directly below it. After the sample (diamond composite sheet) reaches directly below the nozzle 13, the turntable 6 continues to rotate. As the turntable 6 rotates, the ejection mechanism, which rotates with it, drives the execution component. When the execution component operates, it causes a change in the position of the metal tube 12. The metal tube 12 drives the nozzle 13 to remain directly above the sample (i.e., the nozzle 13 moves along with the sample during its movement), ensuring that the nozzle 13 continuously cools the sample surface. The reset component is used to drive the nozzle 13 to reset. After the nozzle 13 cools the sample for a period of time, the ejector mechanism releases control over the actuator, and the reset component drives the actuator to reset. The reset of the actuator then drives the metal tube 12 to reset, and the reset of the metal tube 12 eventually drives the nozzle 13 to reset, so that the nozzle 13 can continuously cool the sample in the next group.

[0025] As one implementation method, such as Figure 6 and Figure 7 As shown, the ejection mechanism includes an ejector rod 14, a top plate 15, a side rod 16, and a guide block 17. The ejection mechanism is described in detail below: The two ends of the top rod 14 are slidably connected to the interior of the temperature measuring platform 8 and the turntable 6, respectively. When the turntable 6 rotates, it drives the top rod 14 to perform a circular motion around the center of the turntable 6. The top plate 15 is fixedly connected to the top rod 14. When the top rod 14 is running (i.e., in circular motion), it drives the top plate 15 to perform a circular motion as well. The side rod 16 is fixedly connected to the outside of the top plate 15. At this time, the top plate 15 drives the side rod 16 to perform a circular motion. The guide block... 17 is fixed to the top of the fixed platform 5. When the turntable 6 rotates a certain number of times, the side rod 16 will contact the inclined surface of the guide block 17. Since the position of the guide block 17 is fixed, the side rod 16 will be lifted by the force. The upward movement of the side rod 16 will drive the top plate 15 to move upward. The upward movement of the top plate 15 will eventually drive the top rod 14 to move upward. The upward movement of the top rod 14 will apply a pushing force to the bottom of the heated sample, forcing the sample to separate from the adhesion of the temperature measuring platform 8, which will facilitate the subsequent gripping operation of the robot arm 2.

[0026] Furthermore, such as Figure 9 , Figure 10 and Figure 11 As shown, the execution component includes a trapezoidal block 18, a connecting block 19, two sets of arc-shaped guide rods 20, a fixing frame 21, an arc-shaped baffle 22, and a connecting frame 33. The execution component is described in detail below: The trapezoidal block 18 is slidably connected to the inside of the connecting block 19. As the turntable 6 continues to rotate, the side rod 16 makes a circular motion and contacts the inclined surface of the trapezoidal block 18, applying pressure to it. Both sets of arc-shaped guide rods 20 slide through the connecting block 19, providing support for the connecting block 19 and allowing it to move only along the outer side of the arc-shaped guide rods 20. The fixing frame 21 is fixed to the top of the frame 1, and both ends of the arc-shaped guide rods 20 are fixed to the inner wall of the fixing frame 21. The fixing frame 21 provides support for the two sets of arc-shaped guide rods 20. The arc-shaped baffle 22 is fixed to the outer side of the fixing frame 21, and the arc-shaped baffle 22 is in contact with the end of the trapezoidal block 18 away from the nozzle 13. Due to the arc shape... The position of the baffle 22 is fixed, and the arc-shaped baffle 22 blocks the trapezoidal block 18 from moving inside the connecting block 19. The pressure applied by the side rod 16 to the inclined surface of the trapezoidal block 18 is converted into a thrust. The side rod 16 will then push the trapezoidal block 18 to move, and the movement of the trapezoidal block 18 will drive the connecting block 19 to move. The connecting block 19 will then move along the outside of the two sets of arc-shaped guide rods 20. The connecting frame 33 is fixed to the top of the connecting block 19, and the connecting frame 33 is fixed to the outside of the metal tube 12. When the connecting block 19 moves, the connecting block 19 will also drive the connecting frame 33 to move. The movement of the connecting frame 33 will drive the nozzle 13 to move. At this time, the nozzle 13 will be continuously above the sample, continuously cooling the sample.

[0027] Furthermore, such as Figure 9 , Figure 10 and Figure 11 As shown, the reset mechanism includes spring 23, connecting plate 24, limiting rod 25, support plate 26, and spring 27. The reset mechanism is described in detail below: The first spring 23 is fixed between the fixed frame 21 and the connecting block 19. When the connecting block 19 moves, it pulls the first spring 23, causing it to deform and generate elastic potential energy. The arc-shaped baffle 22 has a limited length. After the trapezoidal block 18 and the connecting block 19 move a certain distance along the outside of the arc-shaped guide rod 20, the arc-shaped baffle 22 will release its obstruction of the trapezoidal block 18. The connecting plate 24 is fixed to the trapezoidal block 18, and the limiting rod 25 is fixed to the outside of the connecting block 19, and the limiting rod 25 slides through the connecting plate 24. The support plate 26 is fixed to the end of the limiting rod 25 away from the connecting plate 24. The second spring 27 is fixed between the support plate 26 and the connecting plate 24. The elastic potential energy of spring 27 is less than that of spring 23. The pressure applied by side rod 16 to the inclined surface of trapezoidal block 18 will push trapezoidal block 18 towards connecting plate 24 when spring 23 is stationary. The movement of trapezoidal block 18 will cause connecting plate 24 to squeeze spring 27, causing spring 27 to deform and generate elastic potential energy. Then, when side rod 16 passes over trapezoidal block 18, side rod 16 releases the squeeze on trapezoidal block 18, and spring 23 and spring 27 will stop being stressed and release their elastic potential energy. Spring 27 pushes trapezoidal block 18 to reset through connecting plate 24, and spring 23 pulls connecting block 19 to reset, so that nozzle 13 returns to its initial position, which is convenient for continuous cooling of the next group of samples.

[0028] As one implementation method, such as Figure 9 , Figure 10 and Figure 11 As shown, the top of the arc-shaped baffle 22 is provided with a slot 28, and an extension plate 29 is embedded inside the slot 28. When it is necessary to increase the cooling time of the nozzle 13 following the sample, the extension plate 29 can be inserted into the extension plate 29. At this time, after the trapezoidal block 18 moves away from the blocking range of the arc-shaped baffle 22, it will be further blocked by the extension plate 29, thereby extending the distance the nozzle 13 moves and increasing the cooling time of the nozzle 13 on the sample. Finally, after the trapezoidal block 18 moves away from the blocking of the extension plate 29, the nozzle 13 will stop following the sample.

[0029] Furthermore, such as Figure 6 and Figure 7 As shown, a spring 30 is sleeved on the outer side of the top rod 14. The spring 30 is fixed between the top plate 15 and the turntable 6. When the side rod 16 moves the top plate 15 upward, the top plate 15 will pull the spring 30. The spring 30 will deform under the force and generate elastic potential energy. After the side rod 16 releases its control over the top plate 15, the spring 30 will release the elastic potential energy and pull the top plate 15 downward to reset. This avoids excessive friction and "jamming" caused by the top rod 14, top plate 15 and side rod 16 falling under the action of gravity.

[0030] Furthermore, such as Figure 6 and Figure 7 As shown, a connecting roller 31 is rotatably connected to the outer side of the side rod 16. The connecting roller 31 is configured to rotate along the surface of the guide block 17 when the side rod 16 contacts the guide block 17, thereby reducing friction and improving the service life of the device.

[0031] Among them, such as Figure 6 and Figure 7 As shown, the top of the guide block 17 has multiple sets of vibration grooves 32. The multiple sets of vibration grooves 32 allow the side rod 16 to float up and down due to the interference of the vibration grooves 32 as it moves along the surface of the guide block 17. The up and down displacement of the side rod 16 is transmitted through the top plate 15, which drives the top rod 14 to make small up and down reciprocating movements in sync, thereby forming a continuous vibration force. The continuous small-amplitude vibration allows the contact surface between the sample and the temperature measuring stage 8 to always be in a micro-sliding state, which is equivalent to turning static friction into dynamic friction. The separation resistance is greatly reduced, which makes it easier for the top rod 14 to separate the sample from the temperature measuring stage 8.

[0032] A method for testing the heat resistance and insulation properties of diamond composite sheets, the method comprising the following steps: S1. Sample loading and heating test: The robotic arm 2 places the sample on the temperature measuring platform 8, and the motor 9 drives the turntable 6 to rotate it above the high-temperature welding gun 3 for heating. At the same time, the high-temperature tester 4 tests the heat resistance and insulation performance of the sample. S2. After the test, the turntable 6 continues to rotate. The side rod 16 contacts the inclined surface of the guide block 17 and rises. The top plate 15 pushes the top rod 14 to move upward, separating the sample from the temperature measuring table 8. The connecting roller 31 on the side rod 16 rolls along the vibration groove 32, causing the top rod 14 to generate micro-vibration to assist separation. S3. Following the cooling process, after the sample is moved to the area below the nozzle 13, the cold air from the air cooler 10 blows through the nozzle 13 to cool it down. At the same time, the rotating side rod 16 pushes the trapezoidal block 18, causing the connecting block 19 to slide along the arc-shaped guide rod 20. The connecting frame 33 drives the nozzle 13 to move synchronously, thus achieving continuous cooling. S4. Reset and material handling: After the side rod 16 passes over the trapezoidal block 18, spring 1 23 and spring 2 27 release their elastic force, pulling the connecting block 19 and pushing the trapezoidal block 18 to reset respectively. The nozzle 13 returns to the initial position, and the cooled sample is sent to the robot arm 2 to be picked up and removed, completing the cycle.

[0033] In this embodiment, the robotic arm 2 first places the diamond composite sheet sample on the top of the temperature measuring platform 8 on the turntable 6; then, the motor 9 drives the turntable 6 to rotate, sending the sample above the high-temperature welding torch 3 for heating, while the high-temperature tester 4 measures its temperature to evaluate its heat resistance and insulation performance; after the test is completed, the turntable 6 continues to rotate, and the ejection mechanism on it operates accordingly. When the side rod 16 fixed to the outside of the top plate 15 contacts and moves along the inclined surface of the guide block 17 fixed to the fixed platform 5, the side rod 16 drives the ejector rod 14 to move upward through the top plate 15, lifting the sample from the temperature measuring platform 8 and separating it. The connecting roller 31 on the outside of the side rod 16 rolls along the vibration groove 32 opened at the top of the guide block 17, causing the ejector rod 14 to generate continuous micro-vibration, further breaking the adhesion; then… When the sample rotates with the turntable 6 to below the nozzle 13, the cold air generated by the cooling fan 10 is blown out of the nozzle 13 through the transmission pipe 11 and the metal pipe 12 to cool the sample. At the same time, the side rod 16 pushes the trapezoidal block 18 in the actuator during rotation, causing the connecting block 19 to slide along the arc-shaped guide rod 20 fixed to the fixed frame 21. This causes the nozzle 13 to move synchronously through the connecting frame 33, achieving continuous cooling. When the side rod 16 passes the trapezoidal block 18, the spring 23 and spring 27 in the reset mechanism release their elastic potential energy, pulling the connecting block 19 and pushing the trapezoidal block 18 to reset, respectively, and the nozzle 13 returns to its initial position. Finally, the cooled sample is sent by the turntable 6 to the robot arm 2 and safely picked up, thus completing one test cycle.

Following the cooling, after the sample is moved to the bottom of the nozzle (13), the cold air from the cold air blower (10) blows and cools it through the nozzle (13). At the same time, the rotating side rod (16) pushes the trapezoidal block (18), causing the connecting block (19) to slide along the arc-shaped guide rod (20). The nozzle (13) is driven to move synchronously through the connecting frame (33) to achieve continuous cooling. S4. Reset and material handling: After the side rod (16) passes over the trapezoidal block (18), spring one (23) and spring two (27) release their elastic force, pulling the connecting block (19) and pushing the trapezoidal block (18) to reset respectively. The nozzle (13) returns to the initial position, and the cooled sample is sent to the robot (2) to be picked up and removed, completing the cycle.
