[0002] The hardness of cast steel balls is an important indicator for evaluating their performance, and the corresponding hardness requirements vary depending on the type of steel ball. In existing technologies, Rockwell hardness testers are commonly used to test the hardness of cast steel balls. However, before testing, operators often visually place the cast steel ball directly at the center of the Rockwell hardness tester's stage, which is inaccurate. If the steel ball is not centered, it will roll on the stage when the indenter contacts it, affecting the testing results. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the existing technology, when testing the hardness of steel balls using a Rockwell hardness tester, the operator usually places the steel ball directly in the center of the worktable by visual inspection. This process is not very accurate. If the steel ball is not in the center, it will roll on the test table when the indenter touches it, thus affecting the testing effect of the device. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a casting steel ball testing device.

[0023] Example 1:

[0024] To prevent the steel ball from rolling during the testing process, combined with Figures 1-4 As shown, a casting steel ball testing device is proposed. A testing mechanism 1 is set up to test the hardness of the steel ball. A fixing mechanism 2 is set on the testing mechanism 1 so that the steel ball can be stably fixed at the center position of the support plate 101. A conversion mechanism 3 is set on the fixing mechanism 2 so as to easily convert the testing point of the steel ball.

[0025] To ensure the steel ball is stably fixed at the center of the support platform, a fixing mechanism 2 is proposed. This mechanism involves two adjusting blocks 205. Two long plates 201 are fixedly connected to the top of the support plate 101. A directional rod 203 is fixedly connected between the two long plates 201. A bidirectional threaded rod 204 is rotatably connected between the two long plates 201. Each adjusting block 205 has a circular groove at its top, and a small telescopic rod 202 is installed in each groove. A connecting block 206 is fixedly connected to the movable end of each small telescopic rod 202. Support rods 207 are rotatably connected to opposite sides of each connecting block 206. Hemispherical fixing covers a208 are fixedly connected to opposite sides of each support rod 207. A connecting plate 209 is fixedly connected to the center of the top of the support plate 101. A fixing rod is fixedly connected to the top of the connecting plate 209, and a hemispherical fixing cover b210 is fixedly connected to the fixing rod. The two threads of the bidirectional threaded rod 204 are respectively connected to the two... The adjusting blocks 205 are threaded together, and both adjusting blocks 205 can slide on the two directional rods 203. The hemispherical fixing cover b210 is located at the center of the support plate 101. The positions of the bidirectional threaded rod 204 and the directional rod 203 are fixed by the two adjusting blocks 205. The bottom of the steel ball is supported by the fixing rod and the hemispherical fixing cover b210. The positions of the two connecting blocks 206 are adjusted by the two small telescopic rods 202. The two hemispherical fixing covers a208 are used to fix and clamp the two sides of the steel ball, ensuring the stability of the steel ball in hardness testing. At the same time, the bidirectional threaded rod 204 can drive the distance between the two hemispherical fixing covers a208 to be adjusted synchronously. The height of the two hemispherical fixing covers a208 can be easily adjusted by the two small telescopic rods 202, so that the device can fix and test steel balls of different specifications, which greatly improves the detection range of the device for steel balls.

[0026] Example 2:

[0027] Based on Example 1, the technical solution proposed in Example 1 is used to solve the problem that in the prior art, when testing the hardness of cast steel balls, most workers visually place the cast steel balls directly at the center of the Rockwell hardness tester's worktable, which has poor accuracy. If the steel ball is not in the center, it will roll on the test table when the indenter touches it, thus affecting the testing effect of the device. However, after testing a certain point of the steel ball, in order to further improve the testing effect of the device, it is usually necessary to change the testing point of the steel ball. In order to facilitate use, manpower consumption should be reduced.

[0028] To facilitate the conversion of the detection points for the steel ball, combined with Figure 1 and Figure 4As shown, a conversion mechanism 3 is proposed. A fixing plate 301 is fixedly connected to the top of each of the two connecting blocks 206. Adjusting gears 302 are rotatably connected to the opposite sides of each fixing plate 301. Fixed gears 303 for driving the two hemispherical fixed covers a208 are rotatably connected to the opposite sides of the two connecting blocks 206. A micro motor 304 is installed on the opposite sides of each of the two fixing plates 301. The two adjusting gears 302 are respectively engaged with the two fixed gears 303. Rubber rings are installed on the side of each of the two hemispherical fixed covers a208 and one hemispherical fixed cover b210 near their center points. The two fixing plates 301... Two micro motors 304 are installed and fixed. Two fixed gears 303 are used to synchronously adjust two hemispherical fixed covers a208. Rubber rings increase the friction between the steel ball and the two hemispherical fixed covers a208, preventing them from sliding easily. The two micro motors 304 drive the adjusting gears 302 on the two fixed plates 301 to rotate simultaneously, so that the two adjusting gears 302 mesh with the two fixed gears 303 respectively, thereby driving the two hemispherical fixed covers a208 to rotate stably around the fixed steel ball, thus detecting and switching the test point below the pressure measuring head 104, improving the detection effect of the device.

[0029] To enable the device to easily test the hardness of steel balls, a testing mechanism 1 is proposed. A support plate 101 is provided, with two small cylinders 102 mounted on its top. The movable ends of the two small cylinders 102 are fixedly connected to a support frame 103. A pressure measuring head 104 is mounted at the center of the bottom of the support frame 103. The support plate 101 fixes the positions of the two small cylinders 102, and the height of the support frame 103 can be easily adjusted by adjusting the two small cylinders 102, allowing the pressure measuring head 104 to test the hardness of the steel balls.
