Description

[Detailed Description of the Invention] The present invention relates to a split-type face milling cutter, and in particular, the cutter member can be easily attached and detached from the outer circumferential direction.

Conventionally, this type of face milling cutter generally has an indexable tip attached to the outer periphery of the milling cutter body, and the indexable tip is mounted in the center using a hole to be attached to and removed from the main shaft of the machine tool.

However, in the direction of the main axis, attaching and detaching operations may be difficult due to the weight of the face milling cutter, the work material, etc. Especially for large diameter cutters, due to their weight, it takes a lot of time to replace them from a safety standpoint. .

Therefore, there is a need for the development of a split type face milling cutter that can be easily and safely attached to and removed from a machine tool in a short period of time.

Therefore, in the present invention, the main body member and the ivy member are shaped separately, and are made in view of the above-mentioned points.
To provide a split type face milling cutter in which these parts can be easily and reliably attached and detached.

Hereinafter, one embodiment of the split type face milling cutter of the present invention will be described with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a main body member which forms an annular body by drilling a center mounting hole 2, and a flange 3 is formed on the outer peripheral portion of the main body member.

A cutter member 6 having a throw-away tip 4 fixed to it by a wedge piece 5 is attached to the outer peripheral portion of the main body member 1.

This cutter member 6 is for dividing the ring into an appropriate number of parts (four parts in the case shown), and is attached to the main body member 1 with bolts 7.

In this case, the bolt 7 is attached so that its axial center line is inclined with respect to the annular surface of the flange 3, as clearly shown in FIG. is pressed against the flange 3.

In this installation, the receiving hole 8 of the cutter member 6 in which the head of the bolt 7 is located is formed as a long hole on the flange 3 side, as shown in FIG. When the cutter member 6 is loosened from the seat 9, the cutter member 6 slides down by its own weight to the position of the guide pin 10.

As clearly shown in FIG. 4, the guide pin 10 has its axial center line parallel to the annular surface of the flange 3, and the receiving hole 11 formed in the cutter member 6 is located on the flange 3 side. Form a long hole in the hole.

Therefore, when the cutter member 6 slides down due to its own weight, the guide pin 10 supports the cutter member 6.

This is for safety reasons, after which the cutter member is removed from the main body 1.

The split type face milling cutter constructed in this way is installed by screwing the bolt 7 into the main body member 1, so that the cutter member 6 can be attached and detached. This is also effective from a safety standpoint, as it prevents heavy objects from falling.

As explained above, the present invention provides a mounting mechanism that allows the cutter member to be removed from the outer circumferential side of the main body member, making it easy to attach and detach the cutter member to the machine tool for large-diameter face milling cutters. This has the advantage that it can be carried out reliably and also provides safety in transporting heavy objects.

Claims (1)

[Scope of utility model registration request] A cutter member 6 consisting of a main body member 1 having a center mounting hole 2 and a flange 3 formed on the outer periphery thereof, and a split ring having a throw-away tip 4 arranged and fixed on the outer edge thereof. In this split-type face milling cutter, the cutter member 6 is installed radially from the outer circumferential portion of the main body member 1 and includes a plurality of mounting bolts 7 and guide pins 10, which are assembled so as to be detachable. The mounting bolt 7 is attached to the main body member 1.
The cutter member 6 is screwed into the cutter member 6 from its outer periphery, and its axial center line is inclined toward the annular surface of the flange 3. The cutter member 6 is located in the receiving hole 8 in which the cutter member 6 can be pressed toward the flange 3,
The guide pin 10 is attached to the main body member 1 so as to protrude from its outer circumferential portion, and its axial center line is parallel to the annular surface of the flange 3, and the guide pin 10 is attached to the main body member 1 so as to protrude from its outer peripheral portion. 6, a receiving hole 11 whose protruding portion becomes an elongated hole toward the flange 3 side.
A split type face milling cutter, characterized in that the cutter member 6 is located inside and the mounting is adapted to support the cutter member 6 which has slipped down under its own weight when the bolt 7 is loosened.
