Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a chip discharging mechanism in a superfinishing planer.

[Conventional technology]

Conventionally, a super-finishing planer, which has a head part equipped with a planing blade above the base and ejects long continuous chips generated during cutting, is a four-sided chip produced when cutting material with a planing blade. Scattered on the surface, it was troublesome to clean up the chips. Also, the chips discharged upward do not fall from the head and fall again on the planer blade, which hinders the chip discharge of the cutting material to be cut next, or the chips get on the cutting edge of the planer blade, and the chip to be cut next. The finish of the material was bad.

In order to eliminate the above-mentioned problems, as shown in Fig. 4, a planer blade
A chip discharging plate 18 extending in the longitudinal direction of 15 is connected to a rotary support shaft 19 to remove chips generated during cutting.
The method of discharging to the planer blade 15 side was adopted.

[Problems to be solved by the device]

However, in the related art as described above, dedicated parts (chip discharge plate 18, rotary support shaft 19) are attached to discharge chips, so the number of parts inevitably increases and the cost increases. Was there.

The purpose of the present invention is to solve the above-mentioned problems of the prior art,
This is to reduce the number of parts in a structure having a chip discharging function and to simplify the structure.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a super-finishing planing machine comprising a head having a rotary table equipped with a planer blade and a base having a material feeding belt facing the head and feeding a cutting material, A chip discharge wall having a shape for guiding the chip discharge direction to the planer blade side is integrally formed on the rotary table in the longitudinal direction of the planer blade.

[Action]

With the above configuration, the chips generated during cutting are guided to the planer blade side while being guided to the chip discharge wall. After cutting, the chips fall off the head and do not hinder the ejection of the next chip to be cut.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a front view of a super-finishing planing board showing an embodiment of the present invention, FIG. 2 is a sectional view of a head portion, and FIG. 3 is a sectional view of the head portion showing a chip discharge state.

In the figure, 1 is a base, and a cutting material 2 is on the upper surface of the base 1.
A head 4 is provided on the base 1 so as to face the base 1, and a circular recess is formed in the center of the head 4.
Forming 4a. The base 1 and the head 4 are connected by a column 5, and the head 4 is lifted and lowered via a feed screw 7 by rotating a lift handle 6. As shown in FIG. 2, a rotary table 8 is embedded in the recess 4a of the head 4, and the rotary table 8 is supported by a table push-up 9 provided on the lower surface of the head 4. The blade opening plate 11 is attached to the front side (right side when viewed from FIG. 2) with the fixing bolt 10 with respect to the feeding direction (left direction when viewed from FIG. 2) in the rotary table 8, and the rear side of the blade opening plate 11 is attached. A front blade 12 and a back blade 13 are attached to the left side (as viewed from FIG. 2) with fixing screws 14 to form a planing blade 15. The rotary table 8 has a chip discharge wall 16 located above the blade plate 11 and facing the cutting edge of the planer blade 15
Chip guide surface of chip discharge wall 16 molded in the longitudinal direction of 15
16a is formed in an arc shape so as to guide the discharge direction of the chips 17 to the planer blade 15 side.

In the above structure, as shown in FIG. 3, first, the cutting material 2 is set on the base 1 and the feed screw 7 is rotated by the elevating handle 6 to lower the head 4 to a predetermined position. Next, the feeding belt 3 is rotated by a motor (not shown) to feed the cutting material 2 to the planer blade 15 side.

The upper surface of the cutting material 2 is cut by the planer blade 15, and the chips 17 produced during the cutting are pushed upward from between the planer blade 15 and the blade plate 11, and as the cutting progresses, the chips 17 become longer, as shown in FIG. While being guided by the arc of the chip guide surface 16a, it is guided to the planer blade 15 side. After the cutting, the chips 17 drop from the head 4 to eliminate the troubles such as preventing the discharge of the chips 17 to be cut next.

Therefore, since the chip discharge wall 16 is simply formed on the rotary table 8, the structure can be made inexpensive and the conventional labor for mounting the chip discharge plate can be omitted.

[Effect of device]

According to the present invention, the function of reliably discharging the chips from the head is performed by the chip discharging wall integrally formed with the rotary table, so that the number of parts can be reduced, the cost can be reduced, and the structure can be simplified.
