Abstract
The utility model relates to a cutting blade for removing burrs of a chamfer surface on the inner wall of a bearing outer ring, which comprises a blade body, wherein one end of the blade body is provided with a cutting edge part, the cutting edge part is provided with two arc cutting edges which are symmetrically arranged, and a horizontal plane lower than the height of the arc cutting edges is arranged between the two arc cutting edges. The cutting blade for removing the bearing outer ring inner wall chamfer surface burrs changes the cutting mode and performance after changing the shape of the cutter, can simultaneously solve the problems of flanging burrs generated during machining and reducing the necessity of increasing working procedures, can also realize one-time machining, realizes simultaneous machining of two end surfaces in one clamping, reduces nearly half of machining time, prolongs the service life of the designed blade by one time compared with the service life of the traditional blade, and achieves the effects of cost reduction and efficiency improvement.
Description
The technical field is as follows:
the utility model relates to the technical field of bearing processing, in particular to a cutting blade for removing burrs of a chamfer surface on the inner wall of a bearing outer ring.
Background art:
the prior bearing outer ring faces great technical difficulty after turning: 1. the product has burr flanging when using a traditional cutting tool 1' (shown in figure 1) in the processing process, if the flanging burr needs to be removed, a process is added, the cost is increased, and time and labor are wasted; 2. both ends of the hard turning product need to be subjected to hard turning, and when the existing traditional cutter is used, one side needs to be cut and then taken down to be replaced and the other side needs to be clamped and machined, so that the time and the labor are wasted, and the yield is delayed.
The utility model has the following contents:
aiming at the problems, the utility model provides the cutting blade for removing the burrs of the chamfer surface on the inner wall of the outer ring of the bearing, which has the advantages of simple structure, good cutting effect and capability of greatly improving the machining efficiency.
The utility model is realized by the following technical scheme:
the cutting blade for removing the burrs of the bearing outer ring inner wall chamfer surface comprises a blade body, wherein one end of the blade body is provided with a cutting edge part, the cutting edge part is provided with two arc cutting edges which are symmetrically arranged, and a horizontal plane lower than the height of the arc cutting edges is arranged between the two arc cutting edges.
In order to ensure the cutting effect, the left arc cutting edge deflects 5 degrees to the left and the right arc cutting edge deflects 5 degrees to the right as an optimization.
In order to avoid interference, the width of the horizontal plane between the two arc cutting edges is larger than that of the arc cutting edges.
The utility model has the following beneficial effects: the cutting blade for removing the bearing outer ring inner wall chamfer surface burrs changes the cutting mode and performance after changing the shape of the cutter, can simultaneously solve the problems of flanging burrs generated during machining and reducing the necessity of increasing working procedures, can also realize one-time machining, realizes simultaneous machining of two end surfaces in one clamping, reduces nearly half of machining time, prolongs the service life of the designed blade by one time compared with the service life of the traditional blade, and achieves the effects of cost reduction and efficiency improvement.
Description of the drawings:
FIG. 1 is a schematic view of a conventional cutting tool of the prior art;
fig. 2 is a schematic structural diagram of a cutting blade for deburring a chamfer surface on the inner wall of a bearing outer ring according to the utility model.
Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model more readily understood by those skilled in the art, and thus will more clearly and distinctly define the scope of the utility model.
The cutting blade for removing the bearing outer ring inner wall chamfer surface burrs as shown in fig. 2 comprises a blade body 1, wherein one end of the blade body 1 is provided with a cutting edge part, the cutting edge part is provided with two arc cutting edges 11 which are symmetrically arranged, a horizontal plane 12 lower than the heights of the arc cutting edges 11 is arranged between the two arc cutting edges 11, the width of the horizontal plane 12 between the two arc cutting edges 11 is greater than that of the arc cutting edges 11, the arc cutting edge 11 on the left side deflects 5 degrees leftwards, and the arc cutting edge 11 on the right side deflects 5 degrees rightwards.
During processing, as shown in fig. 3, the blade body 1 firstly enters from the right side of the product 2, the arc cutting edge on the left side of the blade body 1 performs cutting processing on the right side chamfer 3 of the product 2, after the processing is completed, the blade body 1 moves to the left side of the product 2, then the blade body enters from the left side, the arc cutting edge on the right side of the blade body 1 performs cutting processing on the left side chamfer 3 of the product 2, the blade does not need to be replaced, and the two sides of the product 2 can be processed simultaneously.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "side", "end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: any person skilled in the art can modify or easily conceive the technical solutions described in the foregoing embodiments or equivalent substitutes for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the embodiments of the present invention, and they should be construed as being included therein. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
