Description

Technical Field

[0001] This utility model relates to the field of diamond agglomerated abrasive strength testing technology, and more specifically, it relates to a diamond agglomerated abrasive strength testing device. Background Technology

[0002] Diamond abrasive refers to a new type of abrasive formed by combining fine-grained single abrasive particles with a binder in a certain way. During the grinding process, each abrasive grain forms a grinding edge, and as the surface abrasive grains wear away, the internal abrasive is exposed, forming multiple layers of abrasive participating in the grinding process. Diamond abrasive can be used to make grinding wheels for rough grinding, as well as grinding pads and polishing fluids for precision grinding. It is a major tool in the industrial manufacturing field and has significant practical value. Single-particle compressive strength (also known as static compressive strength) refers to the static pressure required to completely break up superhard material particles, i.e., the crushing resistance of superhard material particles, and is an important technical indicator of the quality of superhard abrasives.

[0003] Current technologies suffer from narrow instrument detection ranges and suffer from high labor intensity, long processing times, and poorly designed devices leading to significant human error and low measurement accuracy. These problems severely impact the efficiency and reliability of diamond agglomerated abrasive measurements, necessitating an urgent development of a strength testing device that achieves both high measurement efficiency and high accuracy.

[0023] Example:

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] Please see Figure 1-2 This utility model provides a technical solution: a diamond agglomerated abrasive strength testing device, including a frame 1, a support 3 fixedly connected to the top of the frame 1, six retaining sleeves 4 fixedly connected to the top of the inner wall of the support 3, each retaining sleeve 4 having a movable strip 5 slidably connected inside, each movable strip 5 having a threaded groove 14 at its top, six drive motors 6 fixedly connected to the top of the support 3, each drive motor 6 having a threaded rod 7 fixedly connected through the support 3, one end of each threaded rod 7 being threaded into one of the six threaded grooves 14, and an upper anvil 8 fixedly connected to the bottom of each of the six movable strips 5. Through the combined action of the drive motors 6, screws, retaining sleeves 4, movable strips 5, upper anvil 8, and lower anvil 11, multiple sets of data can be tested simultaneously. The purpose is to save time and improve efficiency. Each of the six cassettes 4 is fixedly connected to a display 9. By setting the display 9 on the cassette 4, a single testing device can be independently controlled for testing, thus avoiding the mandatory requirement for the number of tests. The top of the bracket 3 is fixedly connected to the base 10, and the top of the base 10 is fixedly connected to six lower anvils 11. Each of the six lower anvils 11 is equipped with a pressure sensor 12. With the arrangement of the upper anvil 8, lower anvil 11 and pressure sensor 12, the pressure sensor 12 is located at the corresponding positions of the upper anvil 8 and lower anvil 11, and the pressure information of the tested particles is collected in real time. The testing time is shorter, the labor intensity is lower, and the test results are more intuitive, thus ensuring higher testing efficiency and testing accuracy.

[0026] Specifically, a controller 13 is provided on one side of the bracket 3, and fixing holes 2 are provided at the four corners of the top of the frame 1. The six clips 4 are all designed in a staggered manner. The base 10 is located below the bracket 3, and the six upper pressing anvils 8 are respectively vertically corresponding to the six lower pressing anvils 11.

[0027] By adopting the above technical solution, the controller 13 can be used to control conventional known devices such as computers. The controller 13 is electrically connected to the drive motor 6, the display 9 and the pressure sensor 12 through wires. The fixing hole 2 is provided to facilitate the fixing of the position of the frame 1.

[0028] The working principle of this utility model is as follows: When in use, place the frame 1 on the table, insert the screw through the fixing hole 2 into the table to fix the position of the frame 1, connect the device to an external power source and connect it to an external computer, adjust the parameters such as range, resolution, accuracy and speed on the computer, and start the test after setting the parameters. The test data will be presented on the computer in the form of data and curves. Place the diamond agglomerated abrasive on the tape, and stick the tape with the sample to be tested above the lower anvil 11. The output shaft of the drive motor 6 drives the threaded rod 7 to rotate. The threaded rod 7 rotates in the threaded groove 14, thereby pushing the movable bar 5 downward. The movable bar 5 falls along the sleeve 4, so that the upper anvil 8 is pressed on the diamond agglomerated abrasive. The pressure sensor 12 feeds back the pressure value to the computer. As the upper anvil 8 continues to fall, the pressure value fed back by the pressure sensor 12 changes accordingly, so that the pressure value forms a test curve from points to lines. Finally, it can be converted into a data table during the data saving process.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
