Digit Control Machine Tool is installed the jockey of emery wheel
Technical field
The utility model relates to a kind of Digit Control Machine Tool parts, relates in particular to a kind of jockey that emery wheel is installed.
Background technology
Digit Control Machine Tool is used very extensive aspect fine finishining now, such as after emery wheel has been installed, be used for processing dragging track, when track is very high to required precision, we just need an energy stable operation when high-speed grinding, the emery wheel of non-jitter, in the prior art, emery wheel is directly installed on the Digit Control Machine Tool by the emery wheel locating shaft, cause the stability of emery wheel not enough, the emery wheel high-speed grinding has jumping phenomena, needs again repeatedly to locate if additionally install the words of fixture additional, cause the axle center of main shaft of numerical control machine tool and emery wheel to have skew, error occurs.
Summary of the invention
Technical problem to be solved in the utility model provides the jockey that a kind of Digit Control Machine Tool is installed emery wheel, defective stably inadequately when solving in the prior art emery wheel high-speed grinding.
Technical scheme
A kind of Digit Control Machine Tool is installed the jockey of emery wheel, constitute by axle (1) and emery wheel locating shaft (2) two parts, described axle (1) comprises the positioning body (11) of a truncated cone-shaped, there is a boss (12) at round platform major part place, the microcephaly is equipped with clamping device (13) in the place, and hole (21) individual and that boss (12) matches is arranged in the middle of the described emery wheel locating shaft (2).
The tapering of the positioning body of described truncated cone-shaped (11) is 7:24.
Described clamping device (13) is a binding nut.
Beneficial effect
The utility model makes more stable that emery wheel is connected with Digit Control Machine Tool, has reduced the shake when the emery wheel high-speed row is changeed, the planar processing precision when guaranteeing grinding.

Fig. 2 is an emery wheel locating shaft structural representation of the present utility model, and a is a left view, and b is a front view.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
A kind of Digit Control Machine Tool is installed the jockey of emery wheel, constitute by axle 1 and emery wheel locating shaft 2 two parts, described axle 1 as shown in Figure 1, positioning body 11 taperings that comprise a truncated cone-shaped are that the main shaft of 7:24 and Digit Control Machine Tool matches, the location, there is a boss 12 at round platform major part place, be connected with the hole 21 on the emery wheel locating shaft 2, play the effect of centering, the microcephaly is equipped with binding nut 13 in the place, when emery wheel with after machine tool chief axis is connected, binding nut 13 clamps the lathe blind rivets.
Shown in 2, emery wheel locating shaft 2 is machined by the metalworking one as shown, and both sides have square key 22 to be connected with the square key of main shaft of numerical control machine tool to match, and screwed hole 23 passes the M16 connecting bolt, is connected and fixed with main shaft of numerical control machine tool, and play emery wheel the location is installed at cam 24 places.
Installation step:
1. earlier on emery wheel locating shaft 2, assemble a flat key, then emery wheel is slowly pushed on the emery wheel locating shaft.
2. dress pad, upper locking nut is eliminated axial force and is pieced together tightly again.
3. in the hole 21 of emery wheel locating shaft 2, insert axle 1 again, must firmly be inserted into the end to axle 1,, arranged so must firmly insert up to air because air is difficult to venting in the hole 21.
4. with nylon sling emery wheel is winched to the main shaft of numerical control machine tool mouth then, align main shaft and slowly push, this moment, driving must be hung steadily.Rotate slowly that the Digit Control Machine Tool clamping device behind the blind rivet locking emery wheel locating shaft, penetrates four connecting bolts of M16 by clamping button again behind the square key that inserts main shaft, slowly fasteningly refill the emery wheel case after fastening until four bolts are whole.
5. must try commentaries on classics after installing and to carry out grinding.
