The invention has the advantages of high processing efficiency and low production cost.

Description

technical field [0001] The invention relates to a rotary drilling mold for processing aluminum skirts of pistons, in particular to a rotary drilling mold capable of arbitrarily indexing inclined holes. Background technique [0002] In mechanical processing, inclined holes are often drilled on the cylindrical surface, especially the combined piston with steel top and aluminum skirt. When processing the aluminum skirt, there are special requirements for small holes that are neither parallel nor perpendicular to the axis. Mass production At the same time, the corresponding tooling is produced and processed in small batches, and the scribing is used to position and drill the holes. In this way, some directional positioning auxiliary tools are also produced, and the drilled holes have large deviations. Especially the market demand is diversified, and the production of the corresponding tooling in small batches is time-consuming. Low machining accuracy, time-consuming and material...
