Description

[Detailed explanation of the idea] This invention relates to a handle hole processing device.

When assembling the frame material A shown in Figure 1, it is customary to use mitered joints between the ends of each sap material B. In this case, as shown in Figures 2 and 3, It is necessary to machine handle holes D' on the fastening surfaces C and C' (which form a 45 degree angle in Figures 2 and 3) of the sapwood B and B'.

However, conventionally, such handle hole processing on the fastening surfaces c and c' was performed by manually or automatically feeding the sapwood B and B' one by one to a circular saw.
Processing was time-consuming and inefficient.

Therefore, the purpose of this invention is to provide a handle hole machining device that can improve the efficiency of handle hole machining.

An embodiment of this invention is shown in FIGS. 4 to 66.

That is, this handle hole machining device has a circular saw 2 installed in a horizontal position on a base 1, and a circular saw 2 placed between the base 1 and the circular saw 2.
A pair of workpiece mounting tables 3, 3 arranged horizontally on the left and right side and capable of moving forward and backward toward the circular saw from mutually opposing directions in the horizontal position; and the workpiece mounting table. 3, 3, and the handle hole machining position of the fastening surface C of the workpiece (sapwood B) protrudes from the edge of the workpiece mounting table 3, 3, and is attached to the circular saw 2. Rulers 4, 4 that regulate the position of the workpieces (sap material B, B) on the workpiece mounting tables 3, 3 face each other; Material B,
B) A top holding member 5 and a side holding member 6 for pressing and fixing B) from the upper surface side and side side thereof, and the circular saw 2 direction of the workpiece mounting table 3 installed on the base 1 and 3. A stopper 7.7 is provided for stopping the advance of the circular saw 2 at a predetermined position and regulating the depth of machining of the handle hole into the workpiece (sap material B) by the circular saw 2.

Each of the upper pressing members 5 and the horizontal pressing members 6 are cylinders, and the movement of the workpiece mounting tables 3, 3 is also performed dynamically by driving the cylinders (not shown).

The circular saw 2 is driven by a belt 11 between a pulley 9 provided on the drive shaft of the motor 8 and a pulley 10 provided on the rotating shaft of the circular saw 2.
I'm hanging on to it.

The stopper 7.7 is a bracket 1 protruding from the base 1.
2, the bolt is screwed sideways to make it possible to rotate and adjust its regulating position.

In FIG. 4, 13 is the workpiece mounting table 3,
3 is a vertical position correction operating device that controls position correction in the vertical direction, and 14 is a workpiece mounting table 3, 3.
This is a longitudinal position correction operating device for controlling the position correction in the longitudinal direction, that is, in the horizontal direction perpendicular to the forward and backward direction of the workpiece mounting tables 3, 3. By operating these devices 13.14, the ruler 4.4 , the workpieces (sapwood B, B) roughly positioned on the workpiece mounting tables 3, 3 by the upper presser member 5 and the side presser member 6 can be corrected to an accurate position with respect to the circular saw 2. That's what I do.

As shown in FIGS. 5 and 6, the rulers 4, 4 directly place the workpiece (sap material B) and place the workpiece on the end position regulating flange 15 which is erected at the end thereof. Place table 3,3
A lower ruler 4a is used to vertically align the machining surface C of the workpiece material (sapwood B) to the edge of the workpiece material (sapwood B), and a lower ruler 4a is placed on the side of the workpiece material (sapwood B) to determine the overall position of the workpiece material (sapwood B). Horizontal ruler to set 4b-2
It consists of 7 parts.

In addition, horizontal rulers 4b are placed on the left and right sides of the workpiece mounting tables 3, 3.
The reason why the positions of contact with the workpiece material (sap material B) are made different is to take into account that the direction of cutting rotation by the circular saw 2 is reversed on the left and right sides.

With this configuration, as shown in FIG. 7, the fastening surface C (processed at an angle of 45 degrees in this example) faces the circular saw 2 side, and the two covers are placed so that the circular saw 2 is sandwiched between them. Processed materials (
Place the sapwood B, B) on the left and right workpiece mounting tables 3, 3.
By positioning with a ruler 4 on top and a presser member 5°6, the handle hole can be easily machined at a desired position simply by advancing the workpiece mounting tables 3, 3 toward the circular saw 2 from the left and right. Moreover, two workpieces (sap material B, B) can be processed simultaneously with one circular saw 2, and processing efficiency can be greatly improved.

Furthermore, due to the presence of the vertical position correction operating device 13 and the longitudinal position correction operating device 14, a workpiece (sapwood B) of a different standard with slightly different thickness and width dimensions is also provided.
Even for machining, the ruler 4 can be used as is without being replaced, and the work efficiency can be further improved.

Furthermore, due to the presence of the stopper 7.7, the delivery can be made at an accurate depth of cut without paying much attention to the degree of advancement of the workpiece mounting tables 3, 3, making the machining work even easier. can.

Note that the lower ruler 4a and the horizontal ruler 4b are not limited to the above-mentioned example, and of course may have any shape depending on the shape and dimensions of the workpiece.

For example, in the case of processing a sap material B' whose thickness dimension t is larger than its width dimension W as shown in FIG. As shown in the figure, using a lower ruler 4'a whose upper surface forms an inclined surface on which the workpiece (sapwood B') is placed,
') so that its side surface is in contact with the upper surface of the lower ruler 4'a, that is, the thickness direction is horizontal. The horizontal ruler 4'b may be positioned in an inclined position so as to be able to control the position of the side surface of the sap material B' which is perpendicular to the edge of the sap material B' which is in an inclined position with respect to the horizontal plane.

As described above, the handle hole machining device of this invention consists of a circular saw installed in a horizontal position, and a pair of workpieces that can move forward and backward toward the circular saw, which is placed horizontally on either side of the circular saw. a mounting table; a ruler placed on the workpiece mounting table for regulating the position of the workpiece so that the handle hole machining position on the end face of the workpiece faces the circular saw; A holding member that presses and fixes the workpiece whose position is regulated on the workpiece placement table, and a holding member that stops the workpiece placement table from advancing in the direction of the circular saw at a predetermined position to determine the delivery machining depth by the circular saw. Since it is equipped with a stopper that regulates the width, it has the effect that the hole in the frame edge can be efficiently and accurately processed with a simple operation.
