[0002] The hardness of nickel-phosphorus alloy steel sheets is a crucial indicator of their quality and performance, directly impacting their behavior during subsequent processing and use. For example, in the manufacture of automotive parts, insufficient hardness in the nickel-phosphorus alloy steel sheets can lead to deformation and wear under external forces, affecting vehicle safety and lifespan. In the production of electronic device housings, appropriate hardness ensures good protective performance, preventing damage from collisions and compression. Therefore, sampling and hardness testing are necessary during production. However, existing testing equipment typically includes loading, clamping, and unloading mechanisms; the more complex the mechanism, the more prone it is to damage, leading to frequent maintenance.

[0023] 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.
[0024] In modern industrial production, nickel-phosphorus alloy steel sheets are widely used in many fields such as automobile manufacturing, electronic equipment, and aerospace due to their excellent corrosion resistance, wear resistance, hardness, and good appearance.
[0025] Due to the inherent technical limitations of existing technologies, such as complex structures and high maintenance frequencies, please refer to... Figures 1-4 This embodiment provides a hardness testing device for nickel-phosphorus alloy steel plate production. The device has a simple overall structure, strong compatibility, low maintenance frequency, and is suitable for batch sample testing. It includes a fixed platform 1, with two sets of guide rails 12 mounted on the top of the platform. Movable plates 2 are slidably mounted on the guide rails 12. A material holder 3 is detachably connected to one end of the movable plate 2. A reciprocating moving mechanism 4, which drives the movable plate 2 to move horizontally, is fixed to the side wall of the fixed platform 1. A material hopper 6 is located above the movable plate 2 and is screwed into a fixed frame 5, which is mounted on the fixed platform 1. One side is equipped with a fixed frame 2 7 installed on a fixed platform 1. A cylinder 8 is installed on the top of the fixed frame 2 7, and a hardness testing head 9 is installed at the bottom of the cylinder 8. Before use, take out a sample of the same size according to the size of the material hole 302 on the material seat 3, and then place the sample in the material hopper 6. Use the reciprocating moving mechanism 4 to drive the movable plate 2 to move. The movable plate drives the material seat 3 to move. When the material seat 3 is at the bottom of the material hopper 6, the sample falls directly into the material hole 302. Then the material seat 3 can drive the sample to the position of the cylinder 8. The cylinder 8 drives the hardness testing head 9 to contact the surface of the sample and realize the hardness test.
[0026] Existing testing equipment typically includes a feeding mechanism, clamps, and an unloading mechanism. The more structures there are, the more prone they are to damage, leading to a higher frequency of maintenance. For this issue, please refer to... Figure 2 The reciprocating moving mechanism 4 includes a drive assembly 401 mounted on the side wall of the fixed platform 1. A gear 402 is meshed on the upper part of the drive assembly 401. The gear 402 is fixedly connected to the bottom of the fork arm 403. The bottom of the fork arm 403 is rotatably connected to the fixed platform 1 via a rotating shaft. The top of the fork arm 403 is provided with a fork groove, and a protrusion 404 is slidably connected in the fork groove. The protrusion 404 is fixedly connected to the side wall of the movable plate 2. Further, the drive assembly 401 includes a motor 4011 mounted on the side wall of the fixed platform 1. A rotating block 4012 is fixedly mounted on the output shaft of the motor 4011. One end of the rotating block 4012 is hinged to a connecting rod 4013. The toothed plate 4014 is located below and meshes with the gear 402. The motor 4011 drives the rotating block 4012 to rotate. The rotating block 4012 drives the toothed plate 4014 to move through the connecting rod 4013. The toothed plate 4014 drives the fork arm 403 to rotate through the meshing action with the gear 402. The fork arm 403 drives the protrusion 404 to move through the fork groove. The protrusion 404 drives the movable plate 2 to move. The movable plate 2 drives the material seat 3 to move horizontally. The material seat 3 is located at the positions of the hopper 6, the cylinder 8, and the conveyor belt 10, respectively, corresponding to the steps of feeding, testing, and unloading, which can complete the entire hardness testing of the sample.
[0027] Furthermore, a slide rail 4015 is installed on the side wall of the fixed platform 1, and the toothed plate 4014 is slidably mounted on the slide rail 4015; the slide rail 4015 enables the toothed plate 4014 to remain stable when moving horizontally.
[0028] Since the sample is directly fixed in the material hole 302 of the material holder 3, it is not applicable when dealing with samples of different sizes. To address this issue, a positioning groove 201 and a positioning protrusion 301 are respectively provided at the end of the movable plate 2 that contacts the material holder 3. The positioning protrusion 301 is inserted into the positioning groove 201 and connected by screws. Since the movable plate 2 and the material holder 3 are connected by screws, the material holder 3 can be disassembled and replaced, and a suitable material holder 3 can be replaced according to the size of the sample.
[0029] Furthermore, a through-hole 302 is provided on the material holder 3, and an inclined surface 3021 is provided at the top edge of the material hole 302; the material hole 302 is used to place the sample, so that the sample will not move during the testing process, and there is no need to use a clamp to fix the sample, making the structure simpler.
[0030] After the samples are inspected, they are divided into qualified and unqualified products. To facilitate the removal of unqualified samples, a conveyor belt 10 is installed on one side of the fixed platform 1, and an unqualified box 11 is provided below one side of the conveyor belt 10. After the material seat 3 moves above the conveyor belt 10, the sample will fall from the bottom of the material hole 302 onto the conveyor belt 10. When the sample fails the inspection, the conveyor belt 10 conveys it forward and puts the sample into the unqualified box 11. Conversely, qualified samples are sent backward.
[0031] Furthermore, a guide groove 202 is provided at the bottom of the movable plate 2 to cooperate with the guide rail 12; this allows the movable plate 2 and the guide rail 12 to form a sliding fit relationship, thereby improving the stability of the movable plate 2 during translation.
[0032] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
