Abstract

The invention provides a composite tool for bearing hole machining and a machining method, and belongs to the technical field of machining, the tool comprises a tool handle and a tool body, and the tool handle and the tool body are coaxially arranged. A first convex ring and a second convex ring which correspond to each other are arranged on the cutter body, a first blade is arranged on the first convex ring, a second blade is arranged on the second convex ring, and the first blade and the second blade are facing blades. And a boring blade and / or a chamfering blade are / is also arranged on the cutter body between the first convex ring and the second convex ring. According to the compound tool, the multiple blades are compounded on the same tool body, the production efficiency can be improved, the bearing hole machining cost is reduced, and the production and machining process is more controllable.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a composite tool for machining a bearing hole and a machining method. Background technique [0002] Cylinder block bearing holes are usually rough-bored and fine-bored with boring tools during the machining process. In order to ensure the machining accuracy, the requirements for the tools are usually very strict. Moreover, the machining process of bearing holes includes different processes such as rough boring, fine boring, upper plane milling, reverse milling plane, upper chamfering, reverse chamfering and so on. Six different tools need to be replaced during the bearing hole process. Frequent tool replacement not only increases product processing time and reduces production efficiency, but also increases tool cost, which is not conducive to improving the economic benefits of enterprises. [0003] The prior art CN110883346A discloses a multi-functional boring tool for inner ...
