Description

Technical Field

[0001] This utility model belongs to the field of steel casting processing technology, and specifically relates to a steel casting hardness testing device. Background Technology

[0002] In modern industrial production, steel castings are widely used as key components in many fields such as machinery manufacturing, automotive industry, and aerospace. Their quality directly affects the performance, safety, and service life of products, and hardness, as one of the important indicators for measuring the quality of steel castings, is particularly crucial for accurate testing.

[0003] Application CN201720698951.X discloses a testing fixture suitable for hardness testing, comprising jaws for gripping the object to be tested, a base for mounting the jaws, a cover plate, a connecting rod, a push rod, a compression spring, an operating handle, and a handle lever; the cover plate has a handle for the user to grip; and the base has a mounting groove. This fixture enables rapid gripping of the object to be tested, and the gripping operation is simple and quick.

[0004] However, the hardness testing methods proposed in the aforementioned documents have many drawbacks. During the testing process, steel castings, with their varied shapes, are difficult to precisely fix in the testing position. Even slight positional deviations can lead to significant errors in the test results, failing to accurately reflect the actual hardness of the steel castings. Furthermore, their applicability is limited, and their testing efficiency is low. Operators need to spend considerable time and effort on equipment debugging and process control, making it difficult to meet the demands for rapid and efficient testing in large-scale industrial production. In addition, during the pressure testing phase, some equipment lacks effective buffering and pressure distribution mechanisms, which can easily cause irreversible damage to the steel castings during the testing process. This not only affects the subsequent use of the steel castings but also increases production costs. Utility Model Content

[0026] Example

[0027] Reference Figure 1-4 This is an embodiment of the present invention, which provides a steel casting hardness testing device, comprising,

[0028] The detection assembly 100 includes a base 101, a support plate 102 fixedly connected to the upper end of the base 101, an upright plate 103 fixedly connected to the side wall of the support plate 102, a crossbeam 104 fixedly installed at the end of the upright plate 103, a connecting rod 105 movably inserted into the upper side wall of the crossbeam 104, and a pressure plate 106 fixedly connected to the end of the connecting rod 105, the end of the pressure plate 106 extending above the support plate 102.

[0029] The positioning component 200 includes a slide rail 201 fixedly connected to the upper side wall of the support plate 102, a slider 202 slidably installed in the middle of the slide rail 201, a material support plate 203 fixedly connected to the upper end of the slider 202, and a test mold base 204 fixedly connected to the end of the material support plate 203. The test mold base 204 is used in conjunction with the pressure plate 106.

[0030] The base 101 serves as the fundamental support for the entire device, firmly placed on the working surface. The support plate 102 is vertically fixed to the upper end of the base 101, providing vertical mounting support for other components. The upright plate 103 is horizontally fixed to the side wall of the support plate 102, extending the installation space to connect the crossbeam 104. The crossbeam 104 is fixedly installed at the end of the upright plate 103, forming a horizontal structure spanning above the support plate 102. The connecting rod 105 is movably inserted into the upper side wall of the crossbeam 104, allowing it to move up and down on the crossbeam 104. The pressure plate 106 is fixedly connected to the end of the connecting rod 105, its lower end extending above the support plate 102, used to apply pressure to the steel casting placed on the support plate 102. The positioning assembly 200 is mainly used for precise positioning of the steel casting, ensuring the accuracy of the inspection. The slide rail 201 is fixedly connected to the upper side wall of the support plate 102, providing a linear motion track. The slider 202 can slide freely on the slide rail 201. The support plate 203 is fixedly connected to the upper end of the slider 202 and moves with the slider 202. The test mold base 204 is fixedly connected to the end of the support plate 203 and is used to place the steel casting to be tested. It is used in conjunction with the pressure plate 106 to test the hardness of the casting.

[0031] Specifically, the positioning component 200 also includes a limiting block 205 fixedly connected to the end of the support plate 102, and the limiting block 205 is engaged with the end of the slide rail 201.

[0032] A limiting block 205 is fixedly connected to the end of the support plate 102. The limiting block 205 is engaged with the end of the slide rail 201. Its function is to limit the sliding range of the slider 202 on the slide rail 201 and prevent the slider 202 from leaving the slide rail 201.

[0033] Furthermore, the positioning component 200 also includes a roller 206 rotatably mounted on the top of the limiting block 205, with the upper end of the roller 206 rolling in contact with the lower end face of the material support plate 203.

[0034] Among them, a roller 206 is rotatably installed on the top of the limiting block 205. The upper end of the roller 206 rolls in contact with the lower end face of the material support plate 203. When the material support plate 203 moves, the roller 206 rotates, effectively reducing the friction when the material support plate 203 moves.

[0035] Furthermore, the positioning component 200 also includes a positioning block 207 slidably mounted on the side wall of the support plate 102, and an insert block 208 fixedly connected to the end of the positioning block 207, the end of the insert block 208 extending to the side wall of the material support plate 203.

[0036] A positioning block 207 is slidably mounted on the side wall of the support plate 102. An insert block 208 is fixedly connected to the end of the positioning block 207, and the end of the insert block 208 extends to the side wall of the material support plate 203. When it is necessary to fix the position of the material support plate 203, the positioning block 207 is pushed so that the insert block 208 is inserted into the corresponding slot in the side wall of the material support plate 203, thereby achieving positioning.

[0037] Preferably, the positioning assembly 200 further includes a horizontal elbow clamp 209 fixedly connected to the side wall of the support plate 102, with the end of the horizontal elbow clamp 209 fixedly connected to the side wall of the positioning block 207.

[0038] In order to facilitate the operation of the positioning block 207, a horizontal elbow clamp 209 is fixedly connected to the side wall of the support plate 102. The end of the horizontal elbow clamp 209 is fixedly connected to the side wall of the positioning block 207. By operating the horizontal elbow clamp 209, the position of the positioning block 207 and the insertion block 208 can be easily controlled.

[0039] It should be noted that the detection assembly 100 also includes a vertical elbow clamp 107 fixedly connected to the upper end of the crossbeam 104, and the end of the vertical elbow clamp 107 is fixedly connected to the upper end of the connecting rod 105.

[0040] To facilitate easy locking of the connecting rod 105, a vertical elbow clamp 107 is fixedly connected to the upper end of the crossbeam 104, with its end fixedly connected to the upper end of the connecting rod 105. When the height of the pressure plate 106 needs to be adjusted, the vertical elbow clamp 107 is released, allowing the connecting rod 105 to move freely; after adjustment, the vertical elbow clamp 107 is clamped to fix the position of the connecting rod 105 and the pressure plate 106.

[0041] Preferably, the detection assembly 100 further includes a spring post 108 fixedly connected to the lower side wall of the pressure plate 106, with the end of the spring post 108 extending above the test mold base 204.

[0042] A spring column 108 is fixedly connected to the lower side wall of the pressure plate 106. The end of the spring column 108 extends above the test mold base 204. The spring column 108 plays a role in buffering and applying pressure evenly during the test, and at the same time facilitates the detection of the state of the steel casting during the hardness test by the control equipment.

[0043] In operation, when testing the hardness of steel castings, the steel casting to be tested is first placed on the test mold base 204. By operating the horizontal elbow clamp 209, the positioning block 207 is released, allowing the slider 202 to slide freely on the slide rail 201, moving the support plate 203, along with the test mold base 204 and the steel casting, to the appropriate testing position. Then, the horizontal elbow clamp 209 is operated again, causing the positioning block 207 to drive the insert block 208 to insert into the side wall of the support plate 203, fixing the position of the support plate 203. At this time, the vertical elbow clamp 107 is adjusted, and the connecting rod 105 is released, causing the pressure plate 106 to descend under gravity. The spring column 108 at the lower end of the pressure plate 106 first contacts the steel casting. As the pressure plate 106 continues to descend, the spring column 108 is compressed, applying gradually increasing pressure to the steel casting, simulating the pressure conditions that the steel casting may withstand in actual use. Based on the deformation of the steel casting under pressure, its hardness is determined to meet the standard. After the test is completed, reverse the operation of the vertical elbow clamp 107 to raise the pressure plate 106, then operate the horizontal elbow clamp 209 to release the positioning block 207, and remove the test mold base 204 and the steel casting to complete one test process.

[0044] In summary, the slide rail 201, slider 202, limit block 205, and positioning block 207 in the positioning assembly 200 ensure that the steel casting is in a precise position during the inspection process, avoiding inaccurate test results due to positional deviations. The design of the roller 206 reduces friction when the support plate 203 moves, making the positioning process smoother. The vertical elbow clamp 107 and horizontal elbow clamp 209 allow operators to easily and quickly adjust the height of the pressure plate 106 and fix the position of the support plate 203, greatly improving inspection efficiency. The spring column 108 at the lower end of the pressure plate 106 acts as a buffer during inspection, preventing damage to the steel casting and ensuring that pressure is evenly distributed on the steel casting during application, making the test results more reliable.
