Abstract
The utility model relates to a screw quick changing milling chuck, which comprises a clamp body, a lock cap and a spring sleeve, wherein, the lock cap is movably fixed at the end part of the clamp body, the inner cavity of the end part of the lock cap is provided with an inner screw, one section of the outer side surface of the spring sleeve is provided with an outer screw which is matched with the inner screw of the lock cap, and a cutting tool is inserted in the spring sleeve which is inserted in the clamp body. The screw quick changing milling chuck of the utility model adopts the mode that the lock cap is connected with the screw of the spring sleeve, and the lock cap can tension or loosen the spring sleeve under the applied force of the screws to realize the replacement of the cutting tool. The utility model has the advantages of novel structure and quick and convenient replacement of the cutting tool. The utility model can avoid the hammering and the squeezing when carrying out the replacement of the cutting tool.
Description
Technical field
The utility model relates to machine tool chuck, especially a kind of spiral quick-change type milling chuck.
Background technology
Very inconvenient when the chuck on the chuck, particularly milling machine on the existing lathe is changed cutter, the locking cap that need pound with a hammer makes cutter break away from locking cap, so easy damage lathe, and can influence the machining accuracy of lathe.
Summary of the invention
The purpose of this utility model just provides a kind of cutter changing spiral quick-change type milling chuck easily and efficiently.
Spiral quick-change type milling chuck of the present utility model comprises clamp, locking cap, spring housing, locking cap is fixed in the clamp end versatilely, locking cap end inner chamber has internal thread, the lateral surface of spring housing is provided with the external screw thread that matches with the locking cap internal thread for one section, cutter is inserted in the spring housing, and spring housing is inserted in the clamp.
Spiral quick-change type milling chuck operation principle of the present utility model is:
To pack in the machine tool chief axis hole with the clamp that institute's use lathe is complementary, and it is fastening with stay-bolt, milling cutter is inserted in the spring housing, go in the locking cap spring housing is left-handed again, and turn locking cap, spring housing is clamp-oned in the clamp under the threaded function pulling force, and milling cutter is clipped, and clamps with the eave tile wrench at last.During tool changing, rotate locking cap with the dextrorotation of eave tile wrench, spring housing can be extracted out the new cutter of cutter changing by the top pine under screw thread reaction pulling force.The different size cutter can screw off spring housing in this way, changes corresponding spring housing.
Spiral quick-change type milling chuck of the present utility model is to link to each other with the spring housing screw thread by locking cap, under threaded function power, the replacing that loose spring housing is realized cutter, its novel structure are strained or pushed up to locking cap, the replacing cutter is efficient and convenient, the hammering in the time of can avoiding cutter changing, extruding.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Spiral quick-change type milling chuck comprises clamp 1, locking cap 2, spring housing 3, locking cap 3 is fixed in clamp 1 end versatilely, locking cap 2 end inner chambers have internal thread 6, the lateral surface of spring housing 3 is provided with the external screw thread 5 that matches with locking cap 2 internal threads 6 for one section, cutter 4 is inserted in the spring housing 3, and spring housing 3 is inserted in the clamp 1.
