Description

Technical Field

[0001] The invention belongs to the technical field of diamond performance testing, in particular to a physical property testing device for artificial diamonds. Background Art

[0002] Diamond is the hardest substance known in nature, and can be widely used in industry and decoration. However, due to the limited reserves of natural diamonds and the difficulty in mining, artificial diamonds have gradually replaced them in industry, and artificial diamonds have broad development prospects.

[0003] Artificial diamonds are manufactured by rearranging the distribution configuration of carbon atoms under high pressure. In order to make them reach the level of industrial application, it is crucial to test their physical properties. Since artificial diamonds are often used in industrial knives, it is necessary to focus on high temperature resistance and hardness testing. The general test method is to directly perform a falling ball impact test, but this method requires a higher experimental platform, and the impact force is adjusted by adjusting the height and weight of the heavy object. It occupies a large area of ​​the site and is inconvenient to operate. In addition, the falling ball will form multiple bounces that cannot be eliminated due to its own elasticity, which may eventually cause the hidden danger of errors in the experimental results.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figures 1 to 10 As shown, the present invention provides a physical property testing device for artificial diamond, comprising an impact assembly 100, and the impact assembly 100 is arranged on a testing table;

[0048] The impact cylinder 300 is disposed at the rear of the impact assembly 100 and is used to impact the impact assembly 100 to move forward;

[0049] The sample clamping assembly 500 is disposed in front of the impact assembly 100 and is used to clamp a diamond sheet or a diamond block;

[0050] The sample clamping assembly 500 includes a jacket 501 with front and rear through holes, a diamond sheet or a diamond block is clamped inside the sample clamping assembly 500 and exposed to the external environment through the through holes, and the impact assembly 100 includes a striker 103 horizontally aligned with the through holes of the sample clamping assembly 500;

[0051] The detection device also includes a high-pressure chamber 200 and an air pump 400 disposed on the detection platform. The high-pressure chamber 200 is connected to the impact cylinder 300 through an electromagnetic valve 201. A pressure gauge 202 is also disposed on the high-pressure chamber 200 for detecting the internal pressure.

[0052] The air pump 400 is connected to the high-pressure chamber 200 to inject air and pressurize it.

[0053] The diamond sample is set in the sample clamping assembly 500, and the diamond sample is firmly clamped by the sample clamping assembly 500. The diamond sample is exposed by the middle through hole of the sample clamping assembly 500, and the impact assembly 100 drives the striker 103 to horizontally impact the diamond sample at high speed through the impact cylinder 300 to perform a hardness test on it. The test mechanism obtained by the above scheme has a high overall integration, a small occupied height and area, and easy adjustment of the impact parameters.

[0054] The air pump first injects gas into the high-pressure chamber 200 to increase the pressure in the high-pressure chamber 200 to reach the set index. Here, the high-pressure chamber 200 serves as a transfer pressure chamber to improve the stability and controllability of the scheme. The high-pressure chamber 200 is connected to the impact cylinder 300 through the solenoid valve 201. The solenoid valve 201 is turned on to release the pressure in the high-pressure chamber 200 into the impact cylinder 300, which can generate an explosive kinetic energy and push the output end of the impact cylinder 300 to eject the impact hammer 102 at high speed. This scheme is similar to the detonation method, but its safety is greatly improved compared to explosives.

[0055] like Figure 4 As shown, the impact assembly 100 also includes a slide rail 104 installed on the channel steel of the detection platform, a slider 101 slidably installed on the slide rail 104, and a top hammer 102 fixedly mounted on the rear side of the slider 101;

[0056] The striker 103 is fixedly mounted in front of the slider 101;

[0057] A striker 301 aligned in a straight line with the top hammer 102 is fixedly mounted on the output end of the impact cylinder 300 .

[0058] The slider 101 is arranged on the slide rail 104 and can slide freely on the slide rail 104. The striker 103 is used to directly impact the diamond sample to be tested. The top hammer 102 is the upper impact surface of the slider 101. The upper striker 103 of the impact cylinder 300 impacts the top hammer 102, protecting the other components of the two from being damaged by direct impact, and effectively realizing kinetic energy transmission. The defect of the difficulty in setting the buffer mechanism caused by the impact cylinder 300 directly impacting the diamond sample is avoided, and the impact cylinder 300 is effectively protected to extend its service life.

[0059] like Figures 1 to 3 As shown, the high pressure chamber 200 is also provided with an air release valve.

[0060] The top of the high-pressure chamber 200 is also equipped with a pressure relief valve. When the internal pressure of the high-pressure chamber 200 exceeds the container load threshold, the pressure can be actively or passively relieved through the internal pressure to further ensure safety.

[0061] like Figures 1 to 4 As shown, the detection device also includes a high-power laser lamp 800 arranged in a straight line with the sample clamping assembly 500, an infrared temperature measurement camera 700 arranged above the sample clamping assembly 500, and an adjustable microscopic camera 900 arranged on the other side of the sample clamping assembly 500 and facing its through hole;

[0062] The sample clamping assembly 500 also includes a jacket unit 1 5011 and a jacket unit 2 5012, which are spliced ​​together by screws 5013. A vertical through groove 5014 is provided on the inner side of the jacket 501 to be vertically aligned with the infrared temperature measurement camera 700 arranged above.

[0063] The high-power laser light 800 is adjusted to focus directly into the through hole of the sample clamping assembly 500 to heat the diamond sample therein. The high-power laser light 800 can generate a temperature of thousands of degrees and accurately heat the diamond sample. Compared with the traditional baking heating method, it protects the related fixtures and other accessories. At the same time, the adjustable microscope camera 900 coaxially arranged with it can observe the dissociation state of the diamond while heating, and can detect the dynamic change process of the physical state of the diamond.

[0064] The vertical through slot 5014 formed on the jacket 501 is vertically aligned with the infrared temperature measuring camera 700. The infrared temperature measuring camera 700 can monitor whether the temperature of the diamond sample reaches the rated test temperature through the vertical through slot 5014, thereby realizing the synchronization of temperature detection and dynamic performance monitoring. The adjustable microscopic camera 900 can be separated from the impact test. By adjusting the camera to deviate, the diamond can be subjected to the impact test next. The adjustment is convenient and the functionality is strong.

[0065] like Figures 3 to 6 As shown, a sample groove 5015 is provided on the outer periphery of the through hole of the jacket unit 1 5011 for placing a diamond sheet or a diamond block, and a top support protrusion 5016 adapted to the sample groove 5015 is provided on the outer periphery of the through hole of the jacket unit 2 5012. The sample groove 5015 and the top support protrusion 5016 cooperate to clamp the diamond sheet or the diamond block inside.

[0066] The sample clamping assembly 500 also includes two mounting sleeves 502 clamped on the outer periphery of the jacket 501 . The two mounting sleeves 502 are horizontally symmetrically arranged. An observation slot vertically aligned with the vertical through slot 5014 and the infrared temperature measurement camera 700 is provided on the mounting sleeves 502 .

[0067] The diamond sample is placed in the sample slot 5015, and the top support protrusion 5016 is inserted into the sample slot 5015 to clamp it, and the screw 5013 is tightened to achieve accurate positioning and alignment with the through hole of the jacket 501, ensuring that it does not deviate after being hit. The sample slot 5015 can be set to a polygonal shape, which is specifically set as needed.

[0068] The mounting sleeve 502 is used to clamp and limit the jacket 501 , and a through hole is provided on the top thereof to align with the vertical through slot 5014 , so that the infrared temperature measuring camera 700 can monitor the temperature of the diamond sample through the through hole and the vertical through slot 5014 .

[0069] like Figures 1 to 3 As shown, the side of the installation sleeve 502 is provided with a vertical slot, which is used to cooperate with the limiting plate 503 installed on the channel steel to achieve positioning;

[0070] A pressure sensor 5017 whose input end is supported on the jacket 501 is provided on the rear side of the mounting sleeve 502 .

[0071] The mounting sleeve 502 and the limiting plate 503 can be quickly assembled through the cooperation of the card slots. The horizontal assembly is firm and simple, and the mounting sleeve 502 can be inserted downward.

[0072] The pressure sensor 5017 measures the impact force on the diamond in the jacket 501 after it is impacted, which is used for subsequent statistical analysis of the relationship between the diamond performance and the impact force, so as to facilitate the analysis of the physical properties of the diamond.

[0073] like Figure 1 and Fig.10 As shown, a buffer cylinder 600 is provided in the extension direction of the output end of the impact cylinder 300;

[0074] The buffer cylinder 600 includes a cylinder body 601 mounted on a testing platform;

[0075] The piston rod 602 is interference fit in the cavity of the cylinder body 601;

[0076] The outer end of the piston rod 602 is located in the travel path of the output end of the impact cylinder 300;

[0077] Both sides of the piston rod 602 are filled with hydraulic oil for buffering. An elastic member is provided on one side of the piston rod 602 to support the piston rod 602 to reset. A two-way valve 603 is provided at the piston end of the piston rod 602.

[0078] The buffer cylinder 600 is used to buffer the output end of the impact cylinder 300. After the hammer 301 hits the top hammer 102, the hammer 301 can be stopped by hitting the output end of the piston rod 602 to prevent the top hammer 102 from being continuously pushed to interfere with it and the transition extension of the output end of the impact cylinder 300 from causing internal damage. The cavity of the cylinder body 601 is divided into two front and rear cavities by the piston of the piston rod 602. The cavity facing the top hammer 102 is filled with hydraulic oil with an interference, while the cavity on one side is partially empty. When the piston rod 602 is hit, it moves to the cavity filled with hydraulic oil on one side to squeeze the cavity, and the hydraulic oil is directed to the other cavity through the two-way valve 603. The two-way valve 603 is a two-way valve with different conduction areas in two directions. When the hydraulic oil is directed from the interference side to the other side, it will be blocked, while when it is directed from the other side to the interference side, it will not be damped. Therefore, after the piston rod 602 is hit, it can convert the impact energy into internal energy and the potential energy of the elastic member, which has an effective damping effect.

[0079] The two-way valve 603 can also be set as a two-way conducting valve with a small conducting area, so that the two-way movement of the piston rod 602 is damped, thereby reducing the complexity of the structure without affecting the purpose of the function.

[0080] The elastic member provided therein will eventually push the piston rod 602 to return to its original position.

[0081] like Figure 1 , Figure 2 and Figure 8 As shown, the adjustable microscopic camera 900 includes a folding rod 901 and a passive cylinder 902 which are hingedly mounted to each other, and a camera mounted on the folded end of the folding rod 901;

[0082] The passive cylinder 902 is used to control the flipping angle of the folding rod 901;

[0083] The input end of the passive cylinder 902 is connected to the solenoid valve 201 .

[0084] When the air pump pressurizes the high-pressure chamber 200, the solenoid valve 201 is connected to the passive cylinder 902 and is cut off from the impact cylinder 300. Therefore, at this time, the pressurized piston rod of the passive cylinder 902 extends to expand the folding angle of the folding rod 901, thereby flipping the camera upward and lifting it to avoid the impact trajectory of the striker 103. This plays the role of automatically lifting the camera to prevent damage to the camera due to negligence. When the internal pressurization of the high-pressure chamber 200 reaches the rated value, the solenoid valve 201 connects the high-pressure chamber 200 and the impact cylinder 300, and cuts off the high-pressure chamber 200 from the passive cylinder 902. Then the impact cylinder 300 drives the impact assembly 100 to impact the diamond sample, but at this time, since the air pressure in the passive cylinder 902 is constant, the camera module remains in a high position and does not affect the impact test. After the test is completed, the solenoid valve 201 will be reset. At this time, the high-pressure chamber 200 is in a medium-low pressure state, the passive cylinder 902 and the high-pressure chamber 200 are connected, and the high pressure in the passive cylinder 902 is transmitted to the high-pressure chamber 200, causing the passive cylinder 902 to return to a medium-low pressure state, and then the camera is slowly placed in place to align with the through hole of the sample clamping assembly 500 to observe the state of the internal diamond after the impact.

[0085] like Figure 2 and Figure 8 As shown, the impact assembly 100 includes an anti-jump damping rod 105 , which is installed on the detection platform and has a telescopic end connected to the slider 101 .

[0086] The telescopic end of the anti-jump damping rod 105 is connected to the slider 101, and the slider 101 will not be damped by the anti-jump damping rod 105 when it slides toward the sample clamping assembly 500. When the striker 103 bounces back after hitting the jacket 501, the anti-jump damping rod 105 provides damping to consume the elastic force, thereby preventing the striker 103 from bouncing on the diamond sample.

[0087] The anti-jump damping rod 105 is a gas rod equipped with a one-way valve flap. When the slider 101 drives the anti-jump damping rod 105 to hit the diamond sample, the anti-jump damping rod 105 draws air from the outside to the inside, and the flap can be opened in one direction without damping, so that the anti-jump damping rod 105 can expand and contract with the slider 101 without damping. The one-way flap is provided with an air hole. When the slider 101 bounces backward, the anti-jump damping rod 105 contracts inward to squeeze the internal air and can only be discharged from the air hole to the outside, thus forming damping to consume elastic potential energy, preventing reciprocating bounce phenomenon, and reducing device damage and test result errors.

[0088] The above is one of the implementation methods adopted by the present application, and the technicians in the relevant field can also expand and set other damping methods through the scheme proposed in the specification of the present application, including but not limited to friction damping under conditions, cylinder spring damping, etc. All of them are foreseeable changes and settings to achieve the technical purpose of the present application.

[0089] The working principle and use process of the present invention:

[0090] Lift the adjustable microscope camera 900, drive the air pump 400 to inject air into the high-pressure chamber 200, observe the parameters on the pressure gauge, stop the air pump 400 when the parameters reach the set value, control the solenoid valve to connect the high-pressure chamber 200 and the impact cylinder 300, and the output end of the impact cylinder 300 is directly equipped with the top hammer 102 through 301, and the striker 103 penetrates into the sample clamping assembly 500 to impact the diamond sample to achieve the impact test.

[0091] The high-power laser lamp 800 is aligned with the through hole of the sample holding assembly 500 and its focal length is adjusted to directly heat the diamond sample. The temperature of the internal diamond is observed through the infrared temperature measuring camera 700, and the thermal dissociation state of the diamond is observed using the adjustable microscope camera 900.

[0092] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0093] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
