Description

Technical Field

[0001] This utility model belongs to the field of diamond wire testing technology, and in particular relates to a diamond wire strength testing device. Background Technology

[0002] Diamond wire is a cutting tool made by firmly fixing high-hardness, high-wear-resistant diamond abrasive grains onto a steel wire matrix through a certain process. It can achieve high-speed cutting and eliminates the need for expensive and environmentally unfriendly abrasive materials such as silicon carbide used in free cutting. The diamond wire cutting process only requires water or water-based cooling and cleaning fluid, which truly realizes environmentally friendly production and manufacturing. The reduction of diamond wire diameter and wire spacing increases the number of slices produced from a single silicon rod and reduces raw material consumption.

[0003] After diamond wire is produced, it needs to be tested. Tensile strength is a basic parameter for evaluating the quality of diamond wire. Diamond wire has a certain bowing during the cutting process. If the tensile strength is not up to standard, the breakage rate will increase. At the same time, tensile strength also reflects the quality of diamond wire and the quality of electroplating to a certain extent. When testing diamond wire, the existing equipment generally winds the two ends of the diamond wire around the winding column and performs tensile testing. It cannot perform strength tests of multiple groups of diamond wires at different strengths at the same time, which is inefficient. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a diamond wire strength testing device, which at least partially solves the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model is as follows: A diamond wire strength testing device includes a base plate for support and fixation. A support plate for support and a pull-down assembly for testing are installed on the upper wall of the base plate. A connecting plate is installed at the upper end of the support plate. A testing assembly is installed on the side of the connecting plate away from the support plate. The testing assembly is located at the upper end of the pull-down assembly. A hydraulic rod is also installed on the upper wall of the base plate. The hydraulic rod is located at the lower end of the pull-down assembly. The movable end of the hydraulic rod is connected to the bottom wall of the pull-down assembly.

[0006] The pull-down assembly includes multiple sets of telescopic rods, which are evenly spaced in a ring on the upper wall of the base plate. Each set of telescopic rods has a spring sleeved on its outer side. The springs are of the same type but different lengths, and provide different tensions to the diamond wire. Each set of springs has a mounting plate at its upper end, which is connected to the upper end of the telescopic rod. A first fixing post is located at the center of the upper wall of the mounting plate for binding and fixing one end of the diamond wire.

[0007] Preferably, the pull-down assembly further includes a lifting plate, the center of which is connected to the movable end of the hydraulic rod. The lifting plate is provided with a first slot, and multiple sets of the first slot are provided in a ring with equal intervals on the lifting plate. The number of the first slots is the same as the number of telescopic rods.

[0008] The telescopic rod and spring are movably disposed through the first slot, and the mounting plate is disposed on the upper wall of the lifting plate; when the hydraulic rod works, it pushes the lifting plate to move upward, and the lifting plate drives the mounting plate to move upward, at which time both the spring and the telescopic rod are in a stretched state.

[0009] Furthermore, the test assembly includes a connecting seat, the upper end of which is connected to the side of the connecting plate away from the support plate, and a fixing plate is installed at the lower end of the connecting seat. The fixing plate is provided with a second slot, and multiple sets of the second slot are provided. The multiple sets of the second slot are evenly arranged in a ring at equal intervals on the fixing plate. The number of the second slots is the same as the number of telescopic rods, and the second slot is located directly above the first slot.

[0010] The testing assembly further includes a testing plate, which is provided in multiple sets. The multiple sets of testing plates are evenly and movably arranged in a ring on a fixed plate. A pressure sensor is installed between the testing plate and the fixed plate. A second fixing post is installed at the center of the bottom wall of the testing plate. The second fixing post is movably disposed through a second slot and is located directly above the first fixing post. The second fixing post is used to bind and fix the other end of the diamond wire.

[0011] Preferably, both the first and second fixing posts are provided with fixing grooves to facilitate the winding and fixing of the diamond wire in the fixing grooves.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows: a spring is sleeved on the outside of each set of telescopic rods. The multiple sets of springs are of the same type but different in length, and provide different tensile forces to the diamond wire. Different tensile force tests can be carried out on the same type of diamond wire. Attached Figure Description

[0020] like Figures 1-3 As shown, a diamond wire strength testing device includes a base plate 1 for support and fixation. A support plate 2 for support and a pull-down assembly 3 for testing are installed on the upper wall of the base plate 1. A connecting plate 4 is installed on the upper end of the support plate 2. A testing assembly 5 is installed on the side of the connecting plate 4 away from the support plate 2. The testing assembly 5 is located directly above the pull-down assembly 3. A hydraulic rod 6 is also installed on the upper wall of the base plate 1. The hydraulic rod 6 is located at the lower end of the pull-down assembly 3, and the movable end of the hydraulic rod 6 is connected to the bottom wall of the pull-down assembly 3.

[0021] The pull-down assembly 3 includes a telescopic rod 7, which is provided in multiple sets. The multiple sets of telescopic rods 7 are evenly arranged in a ring on the upper wall of the base plate 1. A spring 8 is sleeved on the outer side of each set of telescopic rods 7. The multiple sets of springs 8 are of the same type but different in length, and provide different tensions to the diamond wire. A mounting plate 9 is provided at the upper end of each set of springs 8. The mounting plate 9 is connected to the upper end of the telescopic rod 7. A first fixing post 10 is provided at the center of the upper wall of the mounting plate 9 for binding and fixing one end of the diamond wire.

[0022] The pull-down assembly 3 also includes a lifting plate 11. The center of the lifting plate 11 is connected to the movable end of the hydraulic rod 6. The lifting plate 11 is provided with a first slot 12. Multiple sets of the first slot 12 are provided. The multiple sets of the first slot 12 are evenly arranged in a ring on the lifting plate 11 at equal intervals. The number of the first slot 12 is the same as the number of telescopic rods 7.

[0023] It should be noted that the telescopic rod 7 and the spring 8 are movably installed through the first slot 12, and the mounting plate 9 is installed on the upper wall of the lifting plate 11; when the hydraulic rod 6 works, it pushes the lifting plate 11 to move upward, and the lifting plate 11 drives the mounting plate 9 to move upward. At this time, both the spring 8 and the telescopic rod 7 are in a stretched state.

[0024] The test component 5 includes a connecting seat 13. The upper end of the connecting seat 13 is connected to the side of the connecting plate 4 away from the support plate 2. A fixing plate 14 is installed at the lower end of the connecting seat 13. The fixing plate 14 is provided with a second slot 15. Multiple sets of the second slot 15 are arranged in a ring at equal intervals on the fixing plate 14. The number of the second slots 15 is the same as the number of telescopic rods 7. The second slots 15 are located directly above the first slot 12.

[0025] The test assembly 5 also includes a test plate 16, which has multiple sets. The multiple sets of test plates 16 are evenly and movably arranged in a ring on the fixed plate 14. A pressure sensor 17 is installed between the test plate 16 and the fixed plate 14. A second fixing post 18 is installed at the center of the bottom wall of the test plate 16. The second fixing post 18 is movably disposed through the second slot 15. The second fixing post 18 is located directly above the first fixing post 10. The second fixing post 18 is used to bind and fix the other end of the diamond wire.

[0026] Both the first fixing post 10 and the second fixing post 18 are provided with fixing grooves 19, which facilitates the winding and fixing of diamond wire in the fixing grooves 19.

[0027] In practical use, the hydraulic rod 6 pushes the lifting plate 11 upward, and the lifting plate 11 drives the mounting plate 9 upward. At this time, the spring 8 and the telescopic rod 7 are both in a stretched state. Then, the diamond wire is wound and fixed on the corresponding first fixed post 10 and second fixed post 18 respectively. At this time, the diamond wire is in a relaxed state. Then, the hydraulic rod 6 slowly moves downward. Under the action of the spring 8, the mounting plate 9 moves slowly downward against the upper wall of the lifting plate 11, driving the first fixed post 10 to move downward. The first fixed post 10 pulls the diamond wire, and the diamond wire is in a taut state, applying tension to the second fixed post 18. The second fixed post 18 applies tension to the test plate 16, and the test plate 16 squeezes the pressure sensor 17. As the hydraulic rod 6 continues to move downward, the lifting plate 11 also continues to move downward. Due to the different lengths of the springs 8, the mounting plate 9 connected to the longest spring 8 stops moving first, until all the mounting plates 9 are out of contact with the lifting plate 11. Different diamond wires bear different tensions, and the pressure sensor 17 is used to detect the tension.
