This utility model relates to the field of heald frame installation technology for looms, and in particular to a modular heald frame motion coupling mechanism, including a bracket with both ends bent upwards and a first guide rail installed on both sides. The advantages of this utility model are: by setting up a drive motor, crank, first connecting rod, second connecting rod, transmission rod, and actuating rod, the drive motor is energized and operates. Utilizing the crank-rocker mechanism, the slider is driven to circulate up and down within the second guide rail, thereby allowing the first and second heald frames to slide relative to each other between the first guide rails, layering the warp yarns. By setting four adjustment components, the length of the mechanism can be adjusted, thereby adjusting the relative movement amplitude of the first and second heald frames. Furthermore, the structure is simple, combining the advantages of quick assembly and adjustability, while also offering good maintainability. It enables rapid reconstruction of the motion transmission path and assembly positioning, facilitating widespread use.

The invention relates to a preparation method of a lightweight high-toughness beryllium-aluminum composite material, in particular to a preparation method of a lightweight high-toughness beryllium-aluminum composite material capable of obtaining strong interface bonding through matrix alloying. In order to solve the problem that the mechanical property of the material is limited due to the fact that a beryllium-aluminum interface is not easy to regulate and control in the preparation of the beryllium-aluminum composite material, the invention provides a preparation method for obtaining the lightweight and high-toughness beryllium-aluminum composite material with strong interface combination through matrix alloy component design and interface combination regulation and control. The added Zn element can react with a BeO layer on the surface of the beryllium powder to generate a ZnxBe (1-x) O interface strengthening phase at a Be-Al interface, a stable oxide layer on the surface of the beryllium powder is destroyed, immersion of molten aluminum is facilitated, BeAl2O4 can be formed to realize connection of the beryllium-aluminum interface, and the surface of the beryllium powder is protected. An interface bonding mode is converted from an initial beryllium-aluminum direct bonding type interface to a reaction type interface bonding of strong interface bonding; and the V element can improve the brittleness of beryllium and improve the ductility of the material.
