Abstract
The utility model discloses an adjustable boring cutter for a snap spring groove. The adjustable boring cutter for the snap spring groove comprises a boring bar. An adjusting nut is arranged on the outer circle of the middle of the boring bar, a guiding long groove is axially arranged in the outer circle of the boring bar, a lever is arranged inside the guiding long groove, a cutter head square hole is formed in the head portion of the boring bar, and a cutter head is arranged inside the cutter head square hole. The adjustable boring cutter for the snap spring groove can be sleeved in an inner hole of a main shaft of a boring mill. The adjustable boring cutter can rotate in low speed while the adjusting nut can be adjusted in a manual mode. According to the lever principle, feed amount of the cutter head can be adjusted continuously, and the snap spring groove can be bored. The adjustable boring cutter for the snap spring groove has the advantages of being unique in design, simple in structure, high in production efficiency, capable of machining snap spring grooves in small holes, wherein the snap spring grooves in the small holes are difficult to machine through ordinary boring mills. Meanwhile, cutters are convenient to assemble and disassemble.
