[0016] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0019] See also Figure 1-3 A Brinell hardness tester positioning tooling, the body 4 is installed on the Brinell hardness tester 1, the Brinell hardness tester 1 includes a lifting platform 2 and a pressing block 3, including a base 41, a square groove is opened on both sides of the base 41, a guide rod 42 is arranged in one square groove, and a bidirectional screw 43 is passed through the other square groove, and a movable frame 46 is connected to each end of the guide rod 42 and the bidirectional screw 43, and a positioning plate 44 is fixedly connected to each of the two movable frames 46, each positioning plate 44 includes a baffle 442 and a support plate 441, and the opposite sides of the two baffles 442 are respectively provided with an arc surface, and the two support plates 441 are inclined. During use, the operator installs the main body 4 on the lifting platform 2, and then rotates the two-way screw 43 with one hand, so that the two moving frames 46 move toward each other under the restriction of the guide rod 42, while the operator holds the part with the other hand. If it is an ordinary block-type part, the operator only needs to place the part on the base 41, and wait for the baffles 442 on the two positioning plates 44 to clamp the part together to test it through the pressing block 3. If it is a bolt-type part, it is necessary to place the larger part of the part on the support plate 441 of the two positioning plates 44, and provide the part with oblique upward support through the inclined support plate 441. At the same time, the two baffles 442 cooperate to lower the part and fix it, and then the hardness test can be started. If it is a spherical part, when the two baffles 442 clamp it, the arc surface of the baffle 442 can increase the clamping degree of the spherical part, thereby ensuring the fixation of the spherical part, and then the hardness test can be carried out. It has a wide range of applications, does not require the operator to frequently replace the positioning device, is simple and convenient to operate, and improves the test efficiency.

[0020] In some embodiments, a knob 45 is fixedly connected to the end of the bidirectional screw 43. The knob 45 can increase the contact area between the operator's hand and the bidirectional screw 43, thereby quickly rotating the bidirectional screw 43, so that the operator does not need to expend too much effort when rotating the bidirectional screw 43, facilitating operation and improving positioning speed.

[0021] In some embodiments, a hole 47 is formed at the bottom of the base 41. The hole 47 is a non-through hole. It not only provides a connection point between the body 4 and the lifting platform 2 to ensure the stability of the connection between the body 4 and the lifting platform 2, but also allows the body 4 to be rotated through the hole 47, so that different parts of the part can be hardness measured.

[0022] In some embodiments, a rubber ring is attached to the hole 47. When the operator inserts the body 4 onto the lifting platform 2, the rubber ring on the hole 47 contacts the lifting platform 2, which can increase the friction between the lifting platform 2 and the base 41, thereby ensuring that the body 4 can be firmly inserted into the lifting platform 2 and the measurement can be carried out smoothly.

[0023] In some embodiments, the body 4 is made of metal. The metal body 4 is wear-resistant and drop-resistant, and has high strength, a long service life, and can be used by the operator to provide strong support for the part with the help of the lifting platform 2, thereby enhancing the bearing capacity of the device and ensuring the accuracy of the part hardness measurement.

[0024] In some embodiments, the top of the Brinell hardness tester 1 is provided with a groove 11, which is the same size as the base 41. The groove 11 can be used to store the body 4, making it convenient for the operator to pick up the body 4 for positioning at any time, thereby improving the speed of part measurement. The inner wall of the groove 11 can be covered with a rubber material to increase the friction between the groove 11 and the base 41, thereby enhancing the stability of the groove 11 to the body 4.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
