Description

Technical Field

[0001] This utility model relates to the technical field of hardness testing equipment, and in particular to a hardness testing device for magnesium-aluminum alloys. Background Technology

[0002] An alloy is a solid product with metallic properties obtained by mixing and melting one metal with one or more other metals or non-metals, cooling and solidifying. Magnesium-aluminum alloys are alloys composed of magnesium as the base and other elements added. When conducting research and development testing, their hardness is generally tested using a hardness tester to determine their hardness performance.

[0003] A search revealed a public disclosure (announcement) number: CN223107424U, which discloses a magnesium-aluminum alloy hardness testing device, relating to the technical field of hardness testing equipment. This utility model includes a constraint mechanism, comprising a base plate and a placement platform fixedly mounted on the upper wall of the base plate, with a magnesium-aluminum alloy block placed on the upper wall of the placement platform; and a testing mechanism, comprising a frame rod fixedly mounted on the upper wall of the mounting plate, with a hydraulic cylinder fixedly connected between the two frame rods. In this magnesium-aluminum alloy hardness testing device, during the testing process, the operator first places the magnesium-aluminum alloy block on the placement platform. Then, the operator drives the hydraulic cylinder to further press down the lower pressure plate. At this time, two wedge-shaped blocks are pressed down, with the ends of the wedge blocks being obliquely shaped, further interacting with the clamping blocks. Utilizing the characteristic of the sliding rod sliding within the sliding groove, the two clamping blocks move relative to each other to clamp and fix the magnesium-aluminum alloy. The pressing test and clamping are integrated, making the operation convenient and quick.

[0004] Although the above scheme utilizes the characteristic of the sliding rod being set in the groove, thereby driving the two clamping blocks to move relative to each other to clamp and fix the magnesium-aluminum alloy, integrating the pressure test and clamping, making the operation convenient and quick, the fixed position of the test pressure rod makes it inconvenient to continuously test different points of the magnesium-aluminum alloy. Therefore, we propose a magnesium-aluminum alloy hardness testing device. Utility Model Content

[0005] The main purpose of this invention is to provide a magnesium-aluminum alloy hardness testing device. By setting a steering unit and a fixing unit, it solves the problem that it is inconvenient to continuously test different points of magnesium-aluminum alloy due to the fixed position of the test pressure rod.

The steering unit includes a fixed base mounted on the top of the main unit, a rotating through hole opened on the top of the fixed base, a rotating shaft movably disposed inside the fixed base and passing through the rotating through hole, and a driving component disposed inside the fixed base. The fixing unit includes a machining table mounted on the top of the rotating shaft, a fixing groove formed on the side wall of the machining table, a threaded shaft movably disposed inside the fixing groove and having threads with opposite directions at both ends, a movable part mounted on the circumferential side of the threaded shaft, a fixing part disposed on the side of the movable part, and a second drive motor mounted on the input end of the threaded shaft.

[0007] Preferably, the main unit includes a workbench and a base mounted on the bottom of the workbench.

[0008] Preferably, the fixing member further includes an incline connecting rod installed on the side wall of the moving member, and a clamping plate installed at the end of the incline connecting rod. The integral structure composed of the moving member and the fixing member has two sets, and the two sets of integral structures composed of the moving member and the fixing member are symmetrically arranged about the bisecting plane of the threaded shaft.

[0010] Preferably, the processing unit includes a gantry mounted on the top of the workbench, a moving slot opened on the side wall of the gantry, a threaded rod movably disposed in the moving slot, a moving seat mounted on the periphery of the threaded rod, a third drive motor mounted on the input end of the threaded rod, and a processing part disposed on the side of the moving seat.

[0011] Preferably, the processed component includes a hydraulic cylinder mounted on the side wall of the movable seat, and a test pressure rod mounted on the telescopic end of the hydraulic cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In this invention, through the configured steering unit and fixing unit, when the magnesium-aluminum alloy needs to be clamped, the magnesium-aluminum alloy is placed on the processing table. When the second drive motor drives the threaded shaft to rotate, the two moving parts can drive the fixing parts to move along the threaded shaft in a direction closer to each other until the two clamping plates clamp the magnesium-aluminum alloy, thus achieving convenient clamping of the magnesium-aluminum alloy. When it is necessary to continuously test different points of the magnesium-aluminum alloy, the third drive motor drives the threaded rod to rotate, causing the moving seat to drive the processing part to move along the threaded rod. At the same time, the first drive motor drives the worm gear to rotate, causing the worm gear to mesh with the worm wheel, thereby causing the rotating shaft to drive the magnesium-aluminum alloy above it to rotate synchronously, thus enabling the test pressure rod to continuously test different points of the magnesium-aluminum alloy.
