Detailed Embodiments

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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.

[0014] An impact toughness determination device for diamond disclosed by the present invention is mainly applied to the scenario where local overheating occurs during the preheating process of the diamond impact toughness determination device, resulting in uneven heating of the diamond specimen because the temperature cannot be detected in time.

[0015] Refer to Figure 1-8 , an impact toughness determination device for diamond, including a determination cabinet 1; A control console 10, fixedly connected between the rear side of the control console 10 and the front side of the determination cabinet 1; A workbench 4, fixedly connected between the bottom end of the workbench 4 and the top end of the determination cabinet 1; An impact tank 5, movably connected inside the workbench 4; An air delivery pipe 7, fixedly connected between the front end of the air delivery pipe 7 and one side of the impact tank 5; A chlorine gas tank 8, fixedly connected between the top end of the chlorine gas tank 8 and the bottom end of the air delivery pipe 7; A temperature detection component 11, located outside the impact tank 5. The temperature detection component 11 includes a temperature detector 1111, and the front end of the temperature detector 1111 is in contact with the outside of the impact tank 5; A temperature reduction component 14, located inside the temperature detection component 11. The temperature reduction component 14 includes symmetric cooling heads 1404, and two positioners 1411 are arranged at the middle position of the symmetric cooling heads 1404.

[0016] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6, the temperature detection component 11 further includes symmetric connecting plates 1101. At the top of the symmetric connecting plates 1101, two symmetric fixing seats 1102 are fixedly connected. On the opposite sides of the fixing seats 1102 away from the control console 10, auxiliary round rods 1103 are fixedly connected. Inside the two fixing seats 1102 close to the control console 10, threaded rods 1104 are movably connected. One end of the threaded rod 1104 close to the chlorine gas tank 8 is connected to a driving motor 1105 through a coupling. Both the outer sides of the threaded rod 1104 and the auxiliary round rod 1103 are movably connected with sliding plates 1106. At the top of the sliding plate 1106, an arc-shaped frame 1107 is fixedly connected. Inside the arc-shaped frame 1107, an arc-shaped gear 1108 is fixedly connected. And inside the arc-shaped frame 1107, a servo motor 1112 is provided. The power output shaft of the servo motor is connected to a movable rod 1110 through a coupling. On the outer side of the movable rod 1110, a rotating gear 1109 is fixedly connected. Between the outer side of the top of the rotating gear 1109 and the arc-shaped gear 1108, they are meshed through tooth grooves. Arc-shaped grooves are opened on both sides of the arc-shaped frame 1107. Between the inside of the arc-shaped groove close to the driving motor 1105 and the outer side of one end of the movable rod 1110, they are movably connected. Inside the arc-shaped groove away from the driving motor 1105, a sliding seat 1113 is movably connected. The front end of the sliding seat 1113 is fixedly connected to the rear side of the driving motor 1105. And both ends of the outer side of the movable rod 1110 are movably connected with connecting frames 1114. Round holes are opened at both ends inside the connecting frames 1114. Inside the round holes, arc-shaped rods 1115 are movably connected. The bottom ends of the arc-shaped rods 1115 are fixedly connected to the inner bottom of the arc-shaped frame 1107. At the bottom of the connecting frame 1114, a retaining member 1116 is fixedly connected. Between the bottom of the retaining member 1116 and the top of the temperature detector 1111, they are fixedly connected.

[0017] Specifically, when performing temperature detection at various positions of the tank body during preheating, the drive motor 1105 is started to drive the threaded rod 1104 to rotate. Since the sliding plate 1106 is simultaneously sleeved on the threaded rod 1104 and the auxiliary round rod 1103, when the threaded rod 1104 rotates, the sliding plate 1106 moves smoothly along the radial direction of the tank body under the guiding action of the threaded rod 1104 and the auxiliary round rod 1103. The sliding seat 1113 slides synchronously in the arc-shaped groove on the side of the arc-shaped frame 1107 close to the drive motor 1105, ensuring the stability of the movement process of the arc-shaped frame 1107 and realizing the adjustment of the radial position. When the arc-shaped frame 1107 moves to the appropriate radial position, the servo motor 1112 inside the arc-shaped frame 1107 is started to drive the movable rod 1110 to rotate, and the rotating gear 1109 on the outside of the movable rod 1110 rotates accordingly. Because the rotating gear 1109 meshes with the arc-shaped gear 1108 on the inner side of the arc-shaped frame 1107 through the tooth groove, the rotating gear 1109 will perform a circular motion along the track of the arc-shaped gear 1108 when rotating, driving the movable rod 1110 to slide in the arc-shaped grooves on both sides of the arc-shaped frame 1107. The connecting frames 1114 at both ends of the movable rod 1110 are connected to the bottom of the arc-shaped frame 1107 through the internal round holes and the arc-shaped rods 1115. As the movable rod 1110 moves, the temperature detector 1111 fixed by the retainer 1116 at the bottom of the connecting frame 1114 scans the surface of the impact tank 5 in an arc-shaped trajectory for circumferential scanning, collecting temperature data at different circumferential positions of the tank body. During the process, accurate temperature detection helps to timely detect abnormal temperatures of the tank body, take measures in advance for adjustment, maintain the thermal stability during equipment operation, and ensure the stable and reliable operation of the entire diamond impact toughness measurement equipment.

[0018] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in a preferred embodiment, symmetric cabinet doors 2 are fixedly connected to the front end of the measurement cabinet 1. The cabinet doors 2 are located below the control console 10. Ventilation openings 3 are fixedly connected to both sides of the measurement cabinet 1. A connection port 6 is fixedly connected to the side of the workbench 4 close to the air delivery pipe 7. A fixed connection is made between the inside of the connection port 6 and the outside of the air delivery pipe 7. A tank cover 9 is movably connected to the side of the impact tank 5 away from the air delivery pipe 7. A sliding member 16 is fixedly connected to the bottom end of the impact tank 5. The bottom end of the sliding member 16 is movably connected to a chute seat 12. A fixed connection is made between the bottom end of the chute seat 12 and the top end of the workbench 4. Sliding rods 15 are fixedly connected to both ends inside the workbench 4. A plurality of sliders 13 are movably connected to the outside of the sliding rods 15.

[0019] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8, the temperature reduction component 14 further includes an annular frame 1401. The bottom end of the annular frame 1401 is fixedly connected to the top end of the connecting plate 1101 near the threaded rod 1104. A cooling tank 1402 is fixedly connected inside the annular frame 1401. One end of the cooling tank 1402 is fixedly connected to a delivery pipe 1403. A sliding circular part 1405 is fixedly connected to the outside of the delivery pipe 1403. An arc-shaped chute is provided at the top end of the arc-shaped frame 1107. The circular sliding part 16 is movably connected inside the arc-shaped chute. The end of the delivery pipe 1403 away from the cooling tank 1402 is fixedly connected to a branch pipe 1409. Both ends of the branch pipe 1409 are fixedly connected to the top end of the cooling head 1404. A belt 1407 is movably connected to the outside of the movable rod 1110. A chute is provided at the top end of the arc-shaped frame 1107. The belt 1407 is movably connected inside the chute. A rotating shaft 1406 is movably connected to the inside of the top end of the belt 1407. The delivery pipe 1403 is wound around the outside of the rotating shaft 1406. One side of the rotating shaft 1406 is movably connected to a connecting and fixing frame 1408. One end of the connecting and fixing frame 1408 is movably connected to the side of the arc-shaped frame 1107 near the driving motor 1105. The top ends of the positioners 1411 are fixedly connected to support plates 1410. Both sides of the opposite sides of the support plates 1410 are fixedly connected to the connecting frame 1114. The branch pipe 1409 is fixedly connected between the top ends of the support plates 1410.

[0020] Specifically, when the temperature is detected to be too high and the high-temperature area is cooled down, since the bottom end of the annular frame 1401 is fixedly connected to the connecting plate 1101, the entire cooling component 14 moves with the temperature detection component 11. At the same time, the sliding circular part 1405 outside the conveying pipe 1403 slides in the arc-shaped chute at the top of the arc-shaped frame 1107, ensuring that the conveying pipe 1403 can flexibly follow the movement of the arc-shaped frame 1107, so that the cooling head 1404 initially approaches the high-temperature area. During the movement of the arc-shaped frame 1107, the movable rod 1110 rotates, and the belt 1407 outside it moves in the chute at the top of the arc-shaped frame 1107, driving the rotation of the rotating shaft 1406. The conveying pipe 1403 wound around the outside of the rotating shaft 1406 is accordingly retracted and extended. According to the distance change between the cooling head 1404 and the cooling tank 1402, the length of the conveying pipe 1403 is automatically adjusted to ensure that the conveying pipe 1403 will not affect the transmission of the cooling medium due to pulling or slack, and ensure the stable connection between the cooling head 1404 and the cooling tank 1402. When the temperature detector 1111 accurately locates the high-temperature area, the locator 1411 is connected to the connecting frame 1114 through the support plate 1410 at the top, further calibrating the position of the cooling head 1404 to accurately align it with the high-temperature area. The cooling medium in the cooling tank 1402 is transported to the cooling head 1404 through the conveying pipe 1403 and the branch pipe 1409. The cooling head 1404 releases the cooling medium to cool down the high-temperature area, realizing the accurate cooling of the high-temperature area of the impact tank 5. It can closely follow the temperature detection component 11, accurately locate the high-temperature area, make the cooling head 1404 directly act on the heat source, avoid over-cooling the normal temperature area, improve the cooling efficiency and effect, and ensure the temperature uniformity of the impact tank 5.

[0021] A method for using an apparatus for measuring the impact toughness of diamond, using an apparatus for measuring the impact toughness of diamond as described above, includes the following steps: Step 1: Start the device. Chlorine gas in the chlorine gas tank 8 is injected into the impact tank 5 through the gas transmission pipe 7 to preheat the tank body. During this process, the temperature detector 1111 in the temperature detection component 11 closely adheres to the outside of the impact tank 5 to monitor the temperature of each part of the tank body in real time. If the temperature of a certain area is detected to be too high and exceeds the preset uniform temperature range, the symmetrically distributed cooling heads 1404 in the cooling component 14 quickly cool down the high-temperature area through the accurate positioning of the intermediate locator 1411 to ensure the uniform temperature inside the impact tank 5 and provide stable environmental conditions for subsequent tests; Step 2: Select the sieved standard diamond specimen, put it together with the steel ball into the specimen tube, and place a gasket to ensure that the specimen is in a horizontal and stable state in the tube. Subsequently, place the specimen tube loaded with the specimen smoothly into the impact tank 5 movably connected inside the workbench 4 to complete the loading work of the specimen and prepare for the impact test; Step 3: The console 10 precisely controls the impact tank 5 to perform impact motion according to a preset program. The impact tank 5 operates according to the established motion trajectory and parameters, so that the steel balls inside generate an impact force on the diamond specimen, simulating the impact process under actual working conditions. During the entire impact test process, the console 10 continuously monitors and records relevant data for subsequent analysis and evaluation of the impact toughness of the diamond.

10. A method for using an impact toughness measurement device for diamond, which uses an impact toughness measurement device for diamond as described in claim 9, characterized in that, It includes the following steps: Step 1: Start the equipment. Chlorine gas in the chlorine gas tank (8) is injected into the impact tank (5) through the gas pipeline (7) to preheat the tank body. During this process, the temperature detector (1111) in the temperature detection component (11) is closely attached to the outside of the impact tank (5) to monitor the temperature of each part of the tank body in real time. If the temperature of a certain area is detected to be too high and exceeds the preset uniform temperature range, the symmetrically distributed cooling heads (1404) in the cooling component (14), through the precise positioning of the intermediate positioner (1411), quickly cool the high-temperature area to ensure the uniform temperature inside the impact tank (5) and provide stable environmental conditions for subsequent tests; Step 2: Select the screened standard diamond specimen, put it together with the steel ball into the specimen tube, and place gaskets to ensure that the specimen is in a horizontal and stable state in the tube. Subsequently, smoothly place the specimen tube loaded with the specimen into the impact tank (5) movably connected inside the workbench (4) to complete the loading work of the specimen and prepare for the impact test; Step 3: The console (10) precisely controls the impact movement of the impact tank (5) according to the preset program. The impact tank (5) operates according to the established movement trajectory and parameters, so that the steel ball inside generates an impact force on the diamond specimen, simulating the impact process under actual working conditions. During the entire impact test process, the console (10) continuously monitors and records relevant data for subsequent analysis and evaluation of the impact toughness of the diamond.
