This invention relates to the field of mechanical assembly tooling technology, specifically to an installation device for a double-layer filter screen of a crusher. The device includes a hollow shaft. Through the cooperation of variable-diameter positioning components at both ends of the hollow shaft and a guiding installation component, a stable coaxial reference can be established using the center hole of the crusher rotor. The connecting rod between the second and first connecting rods drives the contact block to expand radially synchronously, causing the arc-shaped friction block to conform to the hole wall and complete the tooling positioning. No modification to the crusher body structure is required. An auxiliary handle drives the threaded rod to rotate, and the guide diameter formed by the guide frame is adjusted via a pull rod transmission. The adjustment size can be intuitively controlled using a scale and indicator needle. The auxiliary rollers on the guide frame reduce the pushing resistance of the filter screen cylinder, minimizing scratch damage to the inner wall and effectively improving the alignment efficiency and installation accuracy of the inner filter screen cylinder. It can adapt to reference center holes of different diameters and cylindrical workpieces of different specifications, helping to improve the tediousness of manual alignment and enhance the consistency of installation quality.

This application relates to a layered loading and transfer device for layered loading of components, comprising: an upper end plate and a lower end plate arranged opposite to the upper end plate, and at least two guide posts and at least one stop post detachably connected between the upper and lower end plates. Each guide post has a plurality of grooves spaced apart along its axial direction. The upper and lower surfaces of each groove form upper and lower surface surfaces for placing components. The stop post and the upper or lower surface surface together support and define the position of the component to be loaded. The width of the groove along the axial direction of the guide post is greater than the thickness of the component to be loaded. After being loaded into the layered loading and transfer device, the components to be loaded are spaced apart from each other along the axial direction of the guide post. Using the above-described solution of this application, layered loading of components is achieved, reducing scratch damage to components and printing paste layers, improving product yield efficiency, enabling shared use between processes, reducing human error rates, and lowering workload.
