Abstract

The invention relates to the technical field of milling cutter disc welding, in particular to a milling cutter disc welding fixture and a welding method applying the same and solves problems of weldment shape changing and dimensional accuracy reduction due to welding deformation in a welding process of a milling cutter disc. A cutter disc outer ring fixedly sleeves a cutter disc body, and a pre-tightening ring is connected with the cutter disc outer ring through a plurality of groups of threaded connectors and fixed to a base through a screw. The cutter disc body is provided with a plurality of groups of cutter grooves, and cutter disc positioning and clamping devices are arranged in the cutter grooves respectively and fixedly arranged on the base. By arrangement of the positioning and clamping devices in the cutter grooves of the cutter body, cutter groove wall positioning and clamping are completed in a welding process, so that welding deformation in the welding process is avoided; by adjustment of the positioning and clamping devices, control of welding deformation at any time in the welding process can be guaranteed, and the problem of uncontrollable welding deformation is solved.

Description

technical field [0001] The invention relates to the technical field of milling cutter welding, in particular to a milling cutter disc welding tool and a welding method using the tool. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling; each tooth cuts off the allowance of the workpiece intermittently in turn during work. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines; [0003] During the welding process of the milling cutter head, welding deformation will definitely occur. Welding deformation changes the shape of the weldment and reduces the dimensional accuracy; in the production of welded structures, it is very important to reduce welding deformation. Although people have explored a variety of methods to reduce welding deformation, the traditional method is often performed separately after welding, resulting in high cost and low efficie...
