Abstract
The utility model relates to a clamping head of a milling machine. A locking nut 3 is movably connected with a locking ring 4 provided with a conical surface 8 on an inner ring through an annular groove and a steel ball 6. The conical surface of the front end of a spring clamping sleeve 2 is matched with the conical surface 8 on the inner ring of the locking ring 4, and a sleeve returning ring 7 is arranged between the spring clamping sleeve 2 and the locking ring 4. The clamping head has the advantages of uniform clamping force distribution, firm clamping, small possibility of the falling of a cutter, high centering precision, easy sleeve return and no sleeve blocking phenomenon. The utility model is suitable for milling machines or other machine tools to clamp cutters.
Description
The utility model relates to the anchor clamps of the used milling cutter of a kind of milling machine.
Common milling fixture is to fit mutually by the interior inclined-plane of locking nut and the outer inclined-plane of spring chuck, and screw by locking nut.Because the differential seat angle that its two internal and external threads fit clearance produces, can not be fitted fully in two inclined-planes, compression area accounts for 2/3rds of binding face, stressed irregular, serious wear, so reduced the clamping force and the centering precision of chuck, make cutter clamp not strongly, fall easily cutter, also increased the circular runout and the damage spring chuck of milling cutter.In addition, this structure is in use blocked the spring chuck through regular meeting, can not successfully withdraw from; will be with beaing vibrations or the spring clip cover could being taken out with the instrument prying and pulling; operation is extremely inconvenient, influences operating efficiency, also easily machine tool chief axis and anchor clamps is caused certain damage.
The purpose of this utility model is exactly for overcoming the deficiency described in the background technology, and a kind of centering precision height is provided, and clamping is firm, drill drift is easy to novel Clamp of milling machine.
The purpose of this utility model is achieved by the following technical solution:
This Clamp of milling machine comprises collet body and locking nut, it mainly is to be provided with a retaining ring between locking nut and spring chuck, this retaining ring has interior annular conical surface and cannelure, in the locking nut and the cannelure of retaining ring outer peripheral face adapt, the drill drift ring is between the scrobicular ring of the scrobicular ring of spring chuck and retaining ring.Be equipped with steel ball in the cannelure of locking nut and retaining ring junction.The conical surface of spring chuck end and the interior annular conical surface of retaining ring adapt.Said drill drift ring is the elastic circular ring of a band opening.
Fig. 1: the overall structure schematic diagram of chuck.
Fig. 2: the structural representation of retaining ring.
Fig. 3: the structural representation of spring chuck.
Below with reference to accompanying drawing the utility model is done an explanation.
As shown in Figure 1, this chuck mainly is to be made of collet body 1, locking nut 3, spring chuck 2, retaining ring 4.Wherein, on locking nut 3 inner peripheral surfaces, be provided with cannelure 11, the cannelure 10 in having on retaining ring 4 excircles of annular conical surface 8 and cannelure 11 relative engagement of locking nut 3, steel ball 6 is positioned at cannelure 10,11, again by screw 5 sealings.Also be provided with scrobicular ring 13 (referring to Fig. 2) in the retaining ring 4.Be positioned on the spring chuck 2 of collet body 1 and have elastic joint 9, the interior annular conical surface 8 of the taper seat of its front end and retaining ring 4 adapts, and also is provided with a scrobicular ring 12 (referring to Fig. 3) on the excircle of this chuck 2.Between the scrobicular ring 12 of the scrobicular ring 13 of retaining ring 4 and spring chuck 2, be provided with the circular drill drift ring 7 of a band opening.
Chuck after the improvement is owing to designed retaining ring 4, and with locking nut 3 and retaining ring 6 active connections of 4 usefulness steel balls, combinational gap is very little, and can proofread and correct differential seat angle voluntarily, guarantees its centering precision.Locking nut 3 spins by screw thread with collet body 1 front end, and the interior annular conical surface 8 of retaining ring 4 and the taper seat that has spring chuck 2 front ends of elastic joint 9 are fitted tightly, and clamp force distribution is even.And the clamping that the mutual applying of two taper seats is can be with the milling cutter shank that is positioned at spring chuck 2 firm is difficultly fallen cutter and circular runout, does not also damage chuck.The effect of drill drift ring 7 is that spring chuck 2 and retaining ring 4 are connected as a single entity by scrobicular ring 12,13, utilize the elastic principle realization spring chuck 2 of spring chuck 2 to advance and retreat synchronously with locking nut 3, solved the cutting ferrule problem that takes place during chuck uses, easy to use, loading and unloading freely.
The utility model has overcome the deficiency described in the background technology, have reasonable in design, simple in structure, Centering accuracy height, the advantage such as easy to use. The milling machine or other lathe that are suitable for Multiple Type use.
