Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a casing and a tool with a chip discharging mechanism, and in particular, by improving the shape of the casing body, it can be used even if there is interference between a processing jig, a workpiece, and the casing body. .
[0002]
[Prior art]
Conventionally, in this type of casing and tool with a chip discharge mechanism, the casing body is generally provided concentrically with a rotary tool such as a face mill, or has a spiral shape near the chip discharge port. It has become.
[0003]
[Problems to be solved by the invention]
However, in the tool with a chip discharging mechanism, the cylindrical casing body inevitably has a larger diameter than the face mill located on the inner peripheral side. Therefore, when the casing body interferes with the processing jig or the projection of the workpiece, or when a pair of casing bodies interfere with each other as seen in simultaneous processing, the tool with a chip discharging mechanism is In general, it has a problem that it cannot be used.
[0004]
In view of the above, the present invention intends to provide a casing and a tool with a chip discharging mechanism in which the shape of the casing body is improved and a processing jig or the like does not interfere.
[0005]
[Means for Solving the Problems]
The present invention has been made in view of the above-described points, and a front guide is provided at the annular end of the substantially cylindrical casing body, and a chip discharge port is provided at the outer peripheral side thereof. Based on the premise of a casing with a chip discharging mechanism, interference with a processing jig or the like is avoided.
[0006]
That is, the present invention provides a casing with a chip discharge mechanism in which a non-interfering side surface with respect to a processing jig or the like is formed on a part of the outer peripheral side surface of the casing body.
[0007]
In addition, a rotary tool such as a face mill is disposed on the inner peripheral portion of the casing with the chip discharge mechanism, so that a chip discharge space is formed between the rotary tool and the casing body. A tool with a tool is provided.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the casing with a chip discharge mechanism of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 is an explanatory view conceptually showing a casing with a chip discharge mechanism of the present invention. A front guide 2 is provided on the annular end side of the casing body 1, and a fixture 3 is provided on an outer peripheral portion. An air supply hose 4 and an air discharge port 5 are provided. Further, since the casing body 1 and the front guide 2 are of an openable / closable type, a hinge portion 6 and a fastener portion 7 are provided.
[0010]
By the way, as shown in FIGS. 1 and 2, the casing 1 with a chip discharging mechanism is formed with a non-interference side 8 for avoiding interference with a processing jig or the like on a part of the outer peripheral side. ing. In this case, the non-interfering side surface 8 forms a side surface perpendicular to the annular end, and in the configuration of the casing 1 with the chip discharge mechanism, the non-interfering side surface 8 forms part of the casing body 1. Although the internal space is narrowed and the flow of airflow accompanying rotation is deteriorated, it becomes practical because interference with a processing jig or the like can be avoided.
[0011]
FIG. 3 is a conceptual explanatory view showing an embodiment of the tool with a chip discharge mechanism according to the present invention. The casing body 1 described above is attached to the outer portion of the main shaft 10 of the processing machine with mounting screws 11a, 11b, 11c. The mounting plates 12a, 12b and the like are attached in a non-rotating state, and a chip discharge space 13 is formed between the rotating tool 9 and the casing body 1. As a result, the internal space on the right side of the chip discharge space 13 is narrow in the tool with the chip discharge mechanism shown in FIG.
[0012]
For the cutting edge tip 14 provided in the rotary tool 9, appropriate means such as a fixing means using a wedge or a fixing means using a set screw using a tip with a hole can be adopted. Further, a chip guide member (not shown) for guiding chips generated by cutting with the cutting edge tip 14 is, for example, an individual member as shown in JP-A-7-164275. A case where a ring-shaped member extending in a bowl shape at the outer peripheral end as seen in JP-A-1-109014 can be appropriately employed.
[0013]
FIG. 4 is a conceptual explanatory view showing another embodiment of the tool with a chip discharge mechanism of the present invention, and is applied when the projection 15a of the work 15 interferes.
[0014]
That is, the casing body 1 is shown in FIGS. 5 and 6 (a) and 6 (b), but in order to avoid interference by the projection 15a of the work 15 indicated by an imaginary line on a part of the outer peripheral portion thereof, A non-interfering side surface 8 made of an inclined surface is formed. In this case, the components of the casing body 1 are the same as those in FIG. 1, and are provided with a front guide 2, an air supply hose 4, an air discharge port 5, and the like.
[0015]
FIG. 7 shows another embodiment of the tool with a chip discharging mechanism, and the non-interfering side surface 8 includes an annular end side of the casing body 1 as clearly shown in FIGS. 7 and 9. Is formed as an inclined surface on the opposite side. In this case, the non-interfering side surface 8 of FIG. Moreover, the components with which the casing main body 1 is equipped are provided with the front guide 2, the hose 4, the air discharge port 5, etc. similarly to what was mentioned above.
[0016]
FIG. 10 shows still another embodiment of the tool with a chip discharging mechanism, which is applied when the workpiece 15 is cut simultaneously.
[0017]
That is, the tool with a chip discharging mechanism of this embodiment is such that the non-interfering side surfaces 8 face each other, and the gap amount t is configured so that there is no collision in the approaching state as shown in the figure. .
[0018]
In the above embodiments, an air-injection-type casing with an air supply hose 4 and a tool with a chip discharge mechanism have been described. However, an airless system without an air supply hose 4 or a casing main body 1 is described. It is also possible to change to a dust collector suction system in which a duct hose and a dust collector (not shown) are connected to the air discharge port 5, respectively.
[0019]
【The invention's effect】
As described above, since the non-interfering side surface 8 is formed on the outer peripheral portion of the casing body 1 as described above, the present invention can be applied even when the processing jig, the projection 15a of the workpiece 15 and the like interfere. It is possible and has the advantage that effective chip recovery is possible.
