Description

Technical Field

[0001] The utility model relates to the technical field of hardness detection equipment, and particularly relates to a hardness detection device for magnesium alloy. Background Technique

[0002] Magnesium alloy is an alloy composed of magnesium as the base and other elements added. When it is under research and development testing, its hardness is generally detected by a hardness tester to determine its own hardness performance. At present, during the use of the hardness tester, if the hardness of different positions of the magnesium alloy needs to be detected, generally, the position of the magnesium alloy itself needs to be moved, which is time-consuming and laborious, and the use effect is not ideal. Or for the tester used for magnesium alloy, when the size of the magnesium alloy itself is large, it is difficult to position and fix it.

[0003] After retrieval, in the Chinese patent with the publication number of CN 214224834 U, a hardness tester for the research and development testing of high-performance magnesium alloy is mentioned, which relates to the technical field of related equipment for magnesium alloy production.

The middle part of the bottom of the connecting block is connected with a mounting plate. The middle part of the bottom of the mounting plate is slidably connected with a slider through a slide rail. The middle part of the bottom of the slider and the middle part of the inner side of the lower part of the vertical rod are both connected with a hardness tester main body.

[0004] The above device has drawbacks in the specific use process. During the hardness detection of the magnesium alloy by the above device, first, the magnesium alloy needs to be clamped and fixed, and then the hardness of the magnesium alloy can be detected. The operation process is relatively cumbersome. Therefore, the above device needs to be improved. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0024] Embodiment 1:

[0025] Please refer to Figures 1 - 4 as shown in the figure. The present utility model is a hardness detection device for magnesium - aluminum alloy, including

[0026] a restraint mechanism 100, including a bottom plate 101 and a placement table 102 fixedly arranged on the upper wall of the bottom plate 101. A magnesium - aluminum alloy block is placed on the upper wall of the placement table 102. Two groups of guiding components are symmetrically arranged on both sides of the magnesium - aluminum alloy block. A clamping block 103 is arranged above the guiding components. Two mounting plates 104 are symmetrically and fixedly connected to the upper wall of the bottom plate 101. An elastic component is arranged on one side of the clamping block 103;

[0027] The detection mechanism 200 includes a support rod 201 fixedly arranged on the upper wall of the mounting plate 104. A hydraulic cylinder 202 is fixedly connected between the two support rods 201. A hydraulic shaft 203 is provided at the lower end of the hydraulic cylinder 202. A lower pressing plate 204 is fixedly installed on the outer wall of the hydraulic shaft 203. Two wedge-shaped blocks 205 are symmetrically and fixedly connected to the bottom wall of the lower pressing plate 204. The wedge-shaped blocks 205 have a pushing effect on the clamping blocks 103. A notch is provided on one side wall of the wedge-shaped block 205. A test assembly is provided below the hydraulic shaft 203.

[0028] As Figures 1 - 4 can be seen, the guiding assembly includes guide rails 105 and sliding rods 106. The two guide rails 105 are symmetrically and fixedly arranged on the upper wall of the placing table 102. A chute opening is formed on the upper wall of the guide rail 105. The sliding rod 106 is slidably arranged in the chute opening. The upper wall of the sliding rod 106 is fixedly connected to the bottom wall of the clamping block 103.

[0029] The elastic assembly includes a transverse shaft rod 107, a limiting piece 108, a spring 109 and a circular plate 110. A through hole is formed on one side wall of the mounting plate 104. The transverse shaft rod 107 is slidably arranged in the through hole. The limiting piece 108 is fixedly arranged on one side wall of the mounting plate 104 and is movably installed on the outer wall of the transverse shaft rod 107. One side wall of the circular plate 110 is fixedly connected to one end of the transverse shaft rod 107. The spring 109 is arranged between the circular plate 110 and the limiting piece 108 and is sleeved on the outer wall of the transverse shaft rod 107. The other end of the transverse shaft rod 107 passes through the notch and is fixedly connected to one side wall of the clamping block 103.

[0030] As can be seen from the above, during the test, the staff first places the magnesium alloy block on the placing table 102. Then, the staff drives the hydraulic cylinder 202 to further drive the lower pressing plate 204 to press down. At this time, the two wedge-shaped blocks 205 press down. Among them, the end of the wedge-shaped block 205 is in an inclined section shape and further interacts with the clamping block 103. Utilizing the characteristic that the sliding rod 106 is slidably arranged in the chute opening, the two clamping blocks 103 are driven to move relatively to clamp and fix the magnesium alloy. The downward pressing test and clamping are integrated, and the operation is convenient and fast;

[0031] Among them, when the two clamping blocks 103 move relatively, at this time, the spring 109 is compressed. After the hardness of the magnesium alloy is detected, the two wedge-shaped blocks 205 move upward, and the wedge-shaped blocks 205 no longer interact with the clamping blocks 103. The spring 109 returns to its original state, driving the two clamping blocks 103 to move away from each other. Then, after the test is completed, it is convenient for the staff to take away the magnesium alloy block.

A hydraulic shaft 203 is arranged at the lower end of the hydraulic cylinder 202. A lower pressing plate 204 is fixedly installed on the outer wall of the hydraulic shaft 203. Two wedge-shaped blocks 205 are symmetrically and fixedly connected to the bottom wall of the lower pressing plate 204. The wedge-shaped blocks 205 have a pushing effect on the clamping block 103. A notch is arranged on one side wall of the wedge-shaped block 205. A testing component is arranged below the hydraulic shaft 203.
