Abstract
The utility model provides a quick changing device for a chuck of a milling machine. As a steel wire clamping ring with an opening is adopted, and a nut and a quick changing chuck are provided with corresponding beveled edges, the nut can drive the steel wire clamping ring to slide along the beveled edge at the outer side of the nut during screwing process, the diameter is shortened, and the purpose of quick clamping is achieved under the action of the beveled edges of the quick changing chuck. The quick changing device for the chuck of the milling machine is simple in structure and convenient for processing.
Description
Technical field
The utility model has related to a kind of Clamp of milling machine fast replacing device, belongs to milling machine and makes the field.
Background technology
Existing milling machine generally all is to adopt on the chuck to have two projectioies with the fast replacing device of chuck, has the mode of two breach on the nut that is mated, and in the time of use, two projectioies is aimed at two breach respectively, and rotating nut pushes taper hole with chuck; In the time of dismounting nut is reversed, when the protruding alignment notch on the chuck, chuck is taken out.Therefore this kind structure changes trouble owing to need contraposition, and difficulty of processing is also bigger.
Summary of the invention
In order to overcome shortcoming of the prior art, the utility model provides a kind of Clamp of milling machine fast replacing device, comprise collet body, quick chuck and nut, described quick chuck inserts described nut, described nut sleeve is characterized in that in the rib hole of described collet body head: described nut head has a groove, and there is a groove in the described groove outside, the cone head of described quick chuck has one section groove, is provided with a steel wire collar with opening in the groove of described nut.
The groove of described nut matches with the groove of described quick chuck, and the angle of two grooves is 0-90 °, preferably 45 °.
The utility model provides a kind of Clamp of milling machine fast replacing device, owing to take a steel wire collar with opening, and corresponding groove is set on nut and quick chuck, make nut in the process of turning, drive the groove slip of steel wire collar along the nut outside, reduced, and be issued to the purpose of quick chucking in the groove effect of quick chuck.The utility model is simple in structure, and is easy to process.

The specific embodiment
Below be to describe the technical solution of the utility model in detail by accompanying drawing.
As shown in Figure 1, chuck fast replacing device described in the utility model is made up of collet body 1, quick chuck 2, nut 3 and steel wire collar 4 four parts.As shown in Figure 2,45 ° of grooves 6 of processing on the cone 5 of quick chuck 2 heads.As shown in Figure 3, at the endoporus head of nut 3, have a groove 7,45 ° of grooves 8 of the ramp type in groove 7 outsides match with groove 6 on the quick chuck 2.As shown in Figure 4, steel wire collar 4 has an opening 9.Tight 9 pinches of openings, steel wire collar 4 is put into the groove 7 of nut 3.Quick chuck 2 is inserted nuts 3, and nut 3 is enclosed within the head of collet body 1, at this moment quick chuck 2 afterbodys insert in the rib hole of collet body 1 with the transmission moment of torsion.At last nut 3 is tightened, in the process that nut 3 is tightened, it at first is the influence of the groove 8 on the nut 3, make steel wire collar 4 reduced, then be that groove 8 is climbed along the groove 6 on the quick chuck 2 with steel wire collar 4, the influence of the groove 8 on the nut 3 makes steel wire collar 4 reduced, and the groove 6 on the quick chuck 2 makes steel wire collar 4 diameters be tending towards becoming big, steel wire collar 4 is just by more and more tighter like this, thereby clamps quick chuck 2 securely.In the time of dismounting,, just can take out quick chuck 2 easily as long as unscrew nut 3.
Claims (2)
1. Clamp of milling machine fast replacing device, comprise collet body, quick chuck and nut, described quick chuck inserts described nut, described nut sleeve is in the rib hole of described collet body head, it is characterized in that: described nut head has a groove, there is a groove in the described groove outside, and the cone head of described quick chuck has one section groove, is provided with a steel wire collar with opening in the groove of described nut.
2. Clamp of milling machine fast replacing device according to claim 1 is characterized in that: the groove of described nut matches with the groove of described quick chuck, and the angle of two grooves is 0-90 °.
