The technical scheme of the utility model is that: the anti-seismic milling cutter rod comprises a sleeve and a milling cutter head, wherein the sleeve and the milling cutter head are connected through a milling cutter rod body, the milling cutter rod body penetrates through the sleeve and is coaxially arranged, and two ends of the milling cutter rod body extend to the outer side of the sleeve; the milling cutter bar body is connected with the inner wall of the sleeve through a plurality of bearings, one end of the milling cutter bar body is connected with the milling cutter head through an internal thread hole arranged along the central shaft of the milling cutter bar body, and the other end of the milling cutter bar body is connected with the gear through a key and a key groove.
Preferably, the milling cutter rod body and the gear connecting end coaxially extend outwards to form an external thread end, and the external thread end is connected with a spiral ring.
Preferably, the key groove is formed in the inner wall of the gear, and the key is arranged on the milling cutter rod body corresponding to the key groove.
Preferably, the outer diameter of the end of the milling cutter bar body connected with the milling head protruding out of the sleeve is larger than the inner diameter of the sleeve.
Preferably, the orifice of the internal thread hole is provided with a smooth part for increasing the hole-entering depth of the milling head.
Preferably, four bearings are provided.
Compared with the prior art, the utility model has the advantages that:
the utility model discloses well cutter arbor body passes through bearing and bushing, wherein one end and cutter head threaded connection, and the other end and gear joint drive milling cutter work through the cutter arbor body at last, and each part is connected firmly, and the antidetonation is effectual, and product machining precision is high.
