Abstract
A magnesium alloy knife sleeve for a numerically controlled lathe aims to solve the problems that the smoothness and the inspirit of a processing surface are caused by bad seismic resistant capabilityof the prior steel knife sleeve, the load of a motor rotor is increased due to heavier weight, so that the service life is shortened, and the like. The magnesium alloy knife sleeve is characterized in that a shaft hole (7) for allowing a knife to be inserted in is formed in the central position of an outer sleeve (1); the outer sleeve (1) is made of magnesium alloy materials; a steel inner sleeve(2) is arranged at the end of a flange, a shaft hole (7) for allowing the knife to be inserted in is also formed in the central position of the steel inner sleeve (2), and the front end of steel inner sleeve (2) is conical, the rear half part of the steel inner sleeve (2) is in the shape of a circular truncated cone, and a positioning convex bar (9) is arranged on the surface of the steel inner sleeve (2) and embedded into a cone-shaped hole formed at the end part of the outer sleeve (1); and a knife fixed bolt hole (3) is formed on the flange. The utility model has the advantages of long mechanical service life, smooth product surface, high cutting accuracy and the like, is an ideal substitute product of the steel knife sleeve, and can be widely applied to the numerically controlled lathe.
Description
One, technical field
The utility model belongs to a kind of machining accessory, relates in particular to a kind of numerically controlled lathe magnesium alloy broach shell.
Two, background technology
Numerically controlled lathe is one of most advanced machinery of field of machining in the world, and a numerically controlled lathe has a plurality of broach shells, and the steel broach shell weight that adopts usually at present is big, influence machinery service life; Particularly its shock resistance is poor, makes the fineness of machinery vibration in motion process causing finished surface and precision be difficult to reach the problem that product quality requires and is difficult to solve all the time.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, for market provides a kind of in light weight, numerically controlled lathe broach shell that anti-seismic performance is good simple in structure, easy to make, with low cost.
The technical solution of the utility model is: it is made up of overcoat and interior cover, the center of overcoat is provided with the axis hole of interspersed cutter, and be provided with in the steel and overlap being provided with flange end, the center of cover also is provided with the axis hole of interspersed cutter in described, its front end is conical, and latter half is a round platform, and its surface is provided with positioning convex strip, be inlaid in the round taper hole of overcoat end setting, and on flange, be provided with the cutter fixing threaded hole.Described overcoat is to be made by magnesium alloy materials, and is provided with groove and fastening screw in a side of its outer surface, the steel stator by bolting in groove.
The beneficial effects of the utility model are: it has good antihunt action, particularly reduces to add the resistance that occur man-hour when fine finishining, alleviates and chatters, thereby reach the fineness of processing, can adapt to the processing of degree of depth bore hole and hard material; Have in light weightly simultaneously, numerically controlled lathe is owing to have a plurality of broach shell needs, thereby alleviates the load of numerically controlled lathe revolution, the prolonged mechanical life-span.Detect by test, the magnesium alloy broach shell is increased to 6D than common steel broach shell attenuation rate from 3D, and the product cutting precision and the surface smoothness that process are improved significantly.
Below in conjunction with accompanying drawing the utility model is further described.
