The invention provides a four-way valve assembly machining method which comprises the following steps that a four-way valve and an aluminum pipe are provided, and the four-way valve is provided with an aluminum connecting part; the four-way valve and the aluminum piping are assembled; one end of the aluminum piping is connected with the aluminum connecting part in a matched mode; and the four-way valve and the aluminum piping which are assembled are welded and fixed through flame brazing or high-frequency welding. The four-way valve is provided with an aluminum connecting part, so that welding connection of the four-way valve and the aluminum piping is facilitated.

The utility model provides a kind of foamed ceramic composite machine bed of integrated cooling runner, including foamed ceramic pedestal, reinforcing rib, workbench, the inside of foamed ceramic pedestal is equipped with the hole structure of net-like distribution, hole structure includes rib hole and runner hole, rib hole is used to fill reinforcing rib, runner hole constitutes cooling medium passage;Runner hole inner wall is equipped with sealing layer, runner hole is equipped with medium inlet and medium outlet on foamed ceramic pedestal side wall;Reinforcing rib is filled in the inner wall of rib hole, and is integrated with foamed ceramic pedestal solidification, form built-in reinforcing framework;Workbench is fixedly arranged on the upper surface of foamed ceramic pedestal, and workbench is integrally connected with reinforcing rib at the orifice of rib hole.This foamed ceramic composite machine bed of integrated cooling runner has active temperature control capability, and has the advantages of lightweight, strong vibration absorption and damping capacity, high structural strength, good dimensional stability.

This invention provides a foamed ceramic composite machine tool bed with layered isolation between flow channels and ribs. It includes a foamed ceramic base with an internal channel structure comprising a cooling layer and a reinforcing layer. The cooling layer is located above the reinforcing layer, and the cooling layer and reinforcing layer are completely isolated by a solid foamed ceramic partition. The cooling layer contains multiple horizontally parallel flow channels, each with a sealing layer on its inner wall. The flow channels also have media inlets and outlets on the sidewalls of the foamed ceramic base. The reinforcing layer contains horizontal and vertical slots arranged in a three-dimensional mesh pattern. Reinforcing ribs fill these slots and are integrally formed with the foamed ceramic base, creating a built-in reinforcing skeleton. This foamed ceramic composite machine tool bed offers advantages such as strong active temperature control, no interference between the flow channels and the skeleton, simple manufacturing process, lightweight design, strong vibration absorption and damping capabilities, high structural strength, and good dimensional stability.
