[0002] Diamond tools are manufactured primarily from diamond particles or powder. Due to their exceptional hardness and wear resistance, they are widely used in various industries and processing fields. Diamond tools come in many varieties, classified by various criteria, including abrasive tools, cutting tools, drilling tools, and dressing tools.

[0003] Wear testing of diamond tools is a crucial step in evaluating their ability to resist wear during use. This approach aims to quantify the wear rate and wear resistance of diamond tools under specific operating conditions to ensure they meet expected service life and performance requirements. Existing methods for testing diamond tool wear often struggle to accurately simulate actual operating environments, resulting in significant discrepancies between test results and actual applications. Furthermore, testing is inefficient and costly. Therefore, developing a testing device that can efficiently and accurately assess the wear resistance of diamond tools is crucial. Utility Model Content

[0016] Furthermore, it also includes a support, which includes a column and a base, and the column is arranged on the support; the shell is connected to the support rod.

[0017] Different from the existing technology, the above technical solution uses a fluid mixture formed by the abrasive particles and grinding powder generated by the diamond tool in actual operation and the coolant required by the diamond tool in actual operation to test the diamond tool sample on the inner wall of the cavity.

[0040] See also Figure 1-Figure 3As shown, the present invention provides a diamond tool wear resistance testing device, comprising a housing 10, wherein the housing 10 has a cavity 101, and a rotating assembly 40 is rotatably connected to the cavity 101; a fluid mixture formed by mixing abrasive particles and grinding powder generated by the diamond tool in actual operation and a coolant required by the diamond tool in actual operation is used to test the diamond tool sample 50 on the inner wall of the cavity 101, and the fluid mixture is introduced into the cavity 101, and then the rotating assembly 40 is rotated in the cavity 101, driving the fluid mixture to collide, grind, and flush the diamond tool sample 50, simulating the actual operating environment of the diamond tool to perform a wear resistance test on the diamond tool sample 50, evaluate the wear resistance of the diamond tool sample 50, improve test efficiency and accuracy, and reduce research and development costs; at the same time, the diamond tool sample 50 is detachably connected to the cavity 101, and the diamond tool sample 50 can be batched and quantitatively tested to ensure the accuracy and repeatability of the test results, so as to achieve rapid improvement of the wear resistance of the diamond tool sample 50, greatly saving research and development time and costs.

[0041] The above-mentioned diamond tool wear resistance testing device can test the wear resistance of diamond tools. Diamond tools include diamond abrasives used for grinding and polishing various materials, such as bonded abrasives (such as grinding wheels, sand tiles, grinding stones, grinding heads, etc.), coated abrasives (such as sanding belts, etc.), and loose abrasives (such as grinding pastes, etc.); diamond cutting tools used for cutting various materials, such as diamond saw blades, diamond wire saws, diamond cutting blades, diamond circular saw blades, band saws, gang saws, rope saws, etc.; diamond drilling tools used for exploration and development in geology, petroleum, coal, metallurgy and other departments, such as drill bits, reamers, and construction engineering drills; diamond dressing tools used for fine dressing of workpieces, such as dressing rollers, dressing pens, dressing blocks, etc., as well as other related diamond tools.

[0042] The following provides an embodiment of a diamond tool wear resistance testing device.

[0043] The housing 10 has a cavity 101 and is provided with an opening communicating with the cavity 101; a cover 20 is provided corresponding to the opening to open and close the opening; a plurality of diamond tool samples 50 are detachably connected to the inner sidewall of the cavity 101;

[0044] The rotating assembly 40 is connected to the cavity 101 and rotates relative to the cavity 101;

[0045] The fluid mixture enters the cavity 101 from the opening, and the rotating assembly 40 rotates relative to the cavity 101 so that the fluid mixture collides, grinds, and flushes the diamond tool sample 50 to perform a wear resistance test on it.

[0046] The housing 10 has a cavity 101 therein. The cavity 101 is used to accommodate the fluid mixture, the rotating assembly 40, and the diamond tool sample 50. Therefore, the size and height of the cavity 101 can be set according to actual needs, that is, they can be set based on the sizes of the fluid mixture, the rotating assembly 40, and the diamond tool sample 50. The housing 10 has an opening connected to the cavity 101, so that the cavity 101 in the housing 10 is a semi-enclosed cavity 101. The fluid mixture can enter the cavity 101 through the opening. Of course, the diamond tool sample 50 can also be removed and installed through the opening. The opening is closed by the cover 20 to form a complete sealed cavity. In this sealed cavity, the fluid mixture, under the action of the rotating assembly 40, collides, rubs, and washes the diamond tool sample 50 to perform wear resistance testing. The cover 20 is used to open and close the opening. During the wear resistance test, the opening is opened by the cover 20 to allow the fluid mixture to enter the cavity 101 from the opening. The opening is then closed by the cover 20, and the rotating assembly 40 rotates within the cavity 101 to allow the fluid mixture to collide, grind, and flush the diamond cutting tool sample to perform a wear resistance test. The cover 20 can be a complete component or a combination of multiple components. The opening is opened and closed by rotating, pushing, pulling, or flipping. The opening can be opened and closed manually or electrically controlled. Preferably, when the cover 20 closes the opening, the cover 20 is sealed with the opening to prevent the fluid mixture from leaking under the action of the rotating assembly 40.

[0047] The above-mentioned diamond tool sample 50 refers to a diamond tool sample that is selected for specific testing or analysis in the diamond tool wear resistance test. It is usually representative and can reflect the overall performance or characteristics of the batch or type of diamond tools. There is no limitation on the shape, size and quantity of the diamond tool sample 50, and it can be set according to the specific wear resistance test requirements. The above-mentioned fluid mixture is formed by mixing the abrasive particles and abrasive powder generated by the diamond tool in actual operation and the coolant required by the diamond tool in actual operation (to flush the abrasive particles and abrasive powder on the diamond tool and cool the diamond tool, etc.), and the wear resistance test of the diamond tool sample 50 is carried out to simulate the actual operating environment of the diamond tool. The following diamond tool takes the diamond cutting tool as an example to further explain the fluid mixture. The diamond cutting tool cuts rock and produces rock particles and rock powder in the actual cutting environment. To simulate the actual operating environment of diamond tools, a certain mass of rock particles, rock powder and the required cooling water are mixed to form a fluid mixture. The fluid mixture collides, grinds and flushes the diamond cutting tool samples to test the wear resistance of the diamond cutting tool samples.

[0048] The rotating assembly 40 is connected to the cavity 101 and rotates relative to the cavity 101. The rotation of the rotating assembly 40 relative to the cavity 101 can be in one of two states: one, the rotating assembly 40 does not rotate, and the cavity 101 rotates relative to the rotating assembly 40; two, the cavity 101 does not rotate, and the rotating assembly 40 rotates relative to the cavity 101; three, both the cavity 101 and the cavity 101 can rotate, with the rotating assembly 40 and the cavity 101 rotating in the same direction but at different speeds. Four, both the cavity 101 and the cavity 101 can rotate, with the rotating assembly 40 and the cavity 101 rotating in opposite directions. Preferably, the rotating assembly 40 and the cavity 101 rotate in opposite directions to hinder the inertia of the fluid mixture formed by the abrasive particles, grinding powder, and coolant, thereby enhancing the wear test effect of the diamond tool specimen 50. Although not shown in the figure, it is understood that the rotating assembly 40 also includes a drive unit that drives the rotating assembly 40 to rotate relative to the cavity 101. In this embodiment, the driving unit may be a motor.

[0049] The rotating assembly 40 in the cavity 101 rotates relative to the cavity 101, driving the fluid mixture to collide, grind, and flush the diamond tool sample 50 to perform a wear test on the diamond tool sample 50. The diamond tool wear resistance is evaluated by comparing the diamond tool sample 50 before and after the test. The weight difference of all diamond tool samples 50 before and after the test can be used as a basis for evaluating the wear resistance. The surface condition of the diamond tool before and after the test can also be observed with the naked eye or under a microscope to evaluate the wear resistance, such as whether the diamond tool has slight cracks, pits, or changes in grinding marks. The diamond working surface can also be inspected before and after the test to check the exposed height and distribution of the diamond particles as a basis for evaluating the wear resistance. If the exposed height of the diamond is too low or unevenly distributed, it means that the tool is severely worn. Of course, the grinding force change of the diamond tool before and after the test can also be monitored with the help of a grinding force measuring instrument.

[0050] The present invention is further described in terms of the rotation of the rotating assembly 40. The rotating assembly 40 includes a rotating shaft 401 and a plurality of blades 402 distributed circumferentially along the rotating shaft 401. The rotating shaft 401 drives the plurality of blades 402 to rotate circumferentially around the rotating shaft 401. During the rotation of the blades 402, the fluid mixture is driven to collide, grind, and flush the diamond tool sample 50, thereby performing a wear resistance test on the diamond tool sample 50. Preferably, the rotating shaft 401 is arranged on the central axis of the cavity 101. The central axis of the cavity 101 is a line located at the center of the inner wall of the cavity 101. The rotating shaft 401 is arranged on the central axis of the cavity 101 to ensure that the fluid mixture is evenly distributed in the cavity 101, so that the diamond tool sample 50 is subjected to more uniform and comprehensive collision, grinding and flushing, thereby improving the accuracy and reliability of the test. At the same time, it can balance the load during rotation, reduce vibration and noise during operation, reduce energy loss, improve the flow efficiency and stability of the fluid mixture, and subject the diamond tool sample 50 to a more stable and continuous impact, thereby more accurately evaluating its wear resistance. In certain embodiments, the inner wall of the cavity 101 is filled with diamond tool samples 50 in rows and columns. Specifically, it is preferred that several of the paddles 402 are located in the middle of the width direction of the inner wall of the cavity 101. The paddles 402 are located in the middle of the width direction of the inner wall of the cavity 101 to promote uniform distribution and sufficient collision of the fluid mixture, and can more evenly apply impact force to the diamond tool sample 50, thereby improving the effect of the wear resistance test. In certain embodiments not shown, the plurality of paddles are divided into multiple groups, each group including multiple paddles 402. The multiple groups of paddles 402 are spaced apart along the axial direction of the rotating shaft 401, and the lengths of adjacent paddles 402 can be the same or different. Specifically, it is also preferred that the cavity 101 is cylindrical so that the distance between the paddle 402 and the inner wall of the cavity 101 is equal, that is, the distance between the paddle 402 and the diamond tool sample 50 connected to the inner wall of the cavity 101 is equal, which further promotes the uniform distribution and sufficient collision of the fluid mixture, and can more evenly apply the impact force to the diamond tool sample 50, thereby improving the effect of the wear resistance test.

[0051] In certain embodiments not shown, the paddle 402 is connected to the rotating shaft 401 and has an angle α with the axial projection of the rotating shaft 401. The design of the angle α enables the paddle 402 to more effectively disturb the fluid mixture during rotation, thereby generating a greater lift force on the fluid mixture, thereby increasing the frequency and intensity of collisions between the fluid mixture and the diamond tool sample 50. This helps to more comprehensively evaluate the wear resistance of the diamond tool. The value range of α can be 0°≤α≤60°. By adjusting the size of the angle, the angle and force of the fluid impacting the diamond tool sample 50 can be changed, thereby simulating different test conditions. This helps to more comprehensively evaluate the wear resistance of the diamond tool under different working conditions.

[0052] The diamond tool sample 50 is detachably connected to the inner wall of the cavity 101, and the diamond tool sample 50 can be subjected to batch and quantitative testing to ensure the accuracy and repeatability of the test results. The detachable connection between the diamond tool sample 50 and the cavity 101 can be designed in a detachable connection method according to specific needs and conditions, such as threaded connection, snap connection, etc. For further explanation, the threaded connection is used as an example. A screw hole 102 is provided on the inner wall of the cavity 101 at a position corresponding to the diamond tool sample 50, and a screw 60 is provided on the side of the diamond tool sample 50 corresponding to the cavity 101. The screw 60 is threadedly connected to the screw hole 102.

[0053] The present invention also provides a support 30 comprising a column 301 and a base 302, with the column 301 being mounted on the support 30. The housing 10 is connected to the support rod. The support 30 provides a stable support base for the housing 10, and thus for the diamond tool wear test device, ensuring stability during testing and preventing displacement or tilting due to vibration or external forces.

[0054] The following provides an application example of a diamond tool wear resistance testing device. The outer shell is cylindrical, and its cavity 101 has the same shape as the outer shell. The outer shell is assembled from two upper and lower circular plates and side panels. The diameter of the circular plates is 300 mm, and the width of the side panels is 200 mm. Both the circular plates and the side panels are made of wear-resistant steel. The central shaft in the rotating assembly 40 is rotatably connected between the two circular plates. Six paddle blades 402 are connected to the circumference of the central shaft. The paddle blades 402 are made of cemented carbide material. The diamond tool specimens 50 are rectangular parallelepipeds with a length of 20 mm, a width of 15 mm, and a height of 15 mm. The diamond tool specimens 50 are evenly distributed in rows and columns on the inner wall of the cavity 101. The back of the diamond tool specimens 50 are connected by bolts and fixed to the prepared screw holes 102 on the inner wall of the cavity 101. A certain mass of a fluid mixture such as rock, rock powder, and water is then poured into the opening of the cavity 101, and the opening is closed by the cover 20. The direction and speed of the rotating assembly 40 and the housing 10 can be set separately as needed, such as the clockwise speed range of the housing 10 is 0-100 r / min, the counterclockwise speed range of the blade is 0-100 r / min, and the test time is 0-24h. The clockwise rotation of the housing 10 is used to cause the diamond tool sample 50 to collide, grind, and flush with the fluid mixture in the housing 10. At the same time, the counterclockwise rotation of the rotating assembly 40 is set to hinder the clockwise movement inertia of the fluid mixture formed by the mixture of abrasive particles, grinding powder and coolant, thereby enhancing the wear test effect of the diamond tool sample 50. The above method can not only simulate the actual operating environment of diamond tool wear-resistant parts and the test results are highly accurate, but also can simultaneously test diamond tool samples 50 with different compositions in batches to achieve rapid improvement of the wear resistance of the diamond tool samples 50, greatly saving R&D time and cost.

[0055] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments described herein, or equivalent structural or process transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields are all included in the scope of protection of the present utility model patent.
