Technical Field
[0001] This application relates to the technical field of steel ball testing, and in particular to a steel ball hardness testing device. Background Technology
[0002] A steel ball is a spherical component made of carbon steel or stainless steel, widely used in industry, construction, and machinery manufacturing, and is an important basic material. In the production and processing of steel balls, hardness is one of the key indicators for measuring quality and performance, reflecting the steel ball's resistance to deformation, wear, and fracture. Therefore, the testing of steel ball hardness is particularly important and usually requires the use of specialized hardness testing equipment.
[0003] In related technologies, the hardness of steel balls is mainly tested using a hardness testing device. This device typically consists of a testing platform and a hardness testing component. Due to the spherical nature of the steel ball, it may move during the testing process. Therefore, to ensure the stability of the steel ball's position, a placement groove is usually opened on the upper surface of the testing platform. By placing the steel ball inside the placement groove, the steel ball is positioned to ensure that the hardness testing component is aligned with the center of the steel ball. However, in actual testing, steel balls of different specifications may have certain size differences, while the size of the placement groove is fixed. This may lead to the hardness testing component being misaligned with the center of the steel ball, potentially affecting the accuracy of the test.
[0004] Therefore, those skilled in the art have provided a steel ball hardness testing device to solve the problems mentioned in the background art. Utility Model Content

Activating the hardness testing component 3 allows for hardness testing of the steel ball placed inside the testing box 1. Furthermore, a support plate 4 is fixedly installed inside the testing box 1, providing support for the placed steel ball. A drive assembly 5, a transmission assembly 6, and multiple adjustment components 7 are movably installed inside the testing box 1. A clamping plate 8 is movably installed on each adjustment component 7, and the clamping plate 8 is movably connected to the support plate 4. The number of adjustment components 7 is... The number of clamping plates can be set to three or more. Multiple adjustment components 7 can be used to set multiple clamping plates 8 one-to-one. The steel ball being tested can be placed between multiple clamping plates 8. Specifically, the user can drive the transmission component 6 to operate through the drive component 5. The operation of the transmission component 6 can simultaneously drive multiple adjustment components 7 to operate. The operation of multiple adjustment components 7 can synchronously adjust the movement of multiple clamping plates 8, so that the steel ball can be clamped and limited by multiple clamping plates 8. The position of multiple clamping plates 8 can be adjusted according to the size of the steel ball, so as to keep the hardness detection component 3 aligned with the center of steel balls of different sizes as much as possible. This can improve the accuracy of the steel ball hardness detection of this application and make this application more conducive to practical use.

The outer wall of the first bevel gear 503 meshes with the outer wall of the bottom end of the transmission assembly 6.
[0039] In this embodiment, when the user rotates the handle 502, the first shaft 501 can control the first bevel gear 503 to rotate, and the rotation of the first bevel gear 503 can drive the transmission assembly 6 to operate.

[0041] In this embodiment, the anti-slip pad 9 increases the friction between itself and the placed steel ball, thereby enhancing the stability of the steel ball's position. When a person rotates the handle 502, the anti-slip strip 10 increases the friction between itself and the person's hand, thus providing a certain anti-slip effect.

The outer wall of the second bevel gear 602 meshes with the outer wall of the first bevel gear 503. The outer wall of the third bevel gear 603 meshes with the outer wall of one end of the adjustment assembly 7.

The outer wall of the fourth bevel gear 702 meshes with the outer wall of the third bevel gear 603.
[0045] In this embodiment, the fourth bevel gear 702, in cooperation with the rotating third bevel gear 603, can control the threaded rod 701 to rotate. While the threaded rod 701 is rotating, the clamping plate 8 can be adjusted to move under the limit of the slide groove 402.
[0046] The implementation principle of the steel ball hardness testing device in this application embodiment is as follows:
[0047] In use, the steel ball to be tested for hardness is placed between multiple clamping plates 8 on the support plate 4. The user drives the transmission component 6 through the drive component 5, which in turn drives multiple adjustment components 7. The operation of the adjustment components 7 synchronously adjusts the movement of the multiple clamping plates 8, thus controlling the clamping plates 8 to clamp and limit the steel ball. Activating the hardness testing component 3 allows for hardness testing of the steel ball. The position of the multiple clamping plates 8 can be adjusted according to the size of the steel ball, thus ensuring that the hardness testing component 3 is aligned with the center of steel balls of different sizes, thereby improving the accuracy of the hardness testing and making the application more practical.
