Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a safety device (processing jig) when performing groove processing, etc. on a woodworking processing machine.

[Background of the idea]

Conventionally, when grooving is performed by protruding a grooving cutter or the like above a table, the workpiece is fed while being manually pressed against a lip fence surface that serves as a guide and the table surface. In this case, since the cutting reaction force of the cutter was large, it was necessary to press the cutter strongly against the table surface, making it impossible to feed the material smoothly. In addition, if the pressing force against the table surface was weak, there was a risk that the material would vibrate or bounce back toward you.

If processed using an automatic material feeding device (feeder), the above-mentioned problems would not occur, but it would be extremely expensive. In addition, automatic material feeding devices are installed on the table surface, so when processing wide materials such as plywood, they get in the way and have to be removed or installed in a different location, which can be time-consuming. Ta.

[Purpose of invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks and increase safety during cutting.

[Summary of the idea]

The present invention focuses on pressing the material with a roller pressed by a compression spring, etc., and a U-shaped holder shaft, which has a material holding member made of the rollers etc. at one end, is rotated by a holder provided on the top surface of the lip fence. It is designed to fit freely.

[Example of idea]

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. 1 is a table. The groove cutter 2 protruding from the surface of the table 1 is driven by an electric motor and a drive device (not shown). A guide bar 3 is fixed to the front end of the table 1, and a lip fence 4 is slidably provided on the guide bar 3. The knob 5 fixes the lip fence 4 and the guide bar 3. A holder 6 is fixed on the lip fence 4 with screws, and a holder shaft 7 is held in the holder 6 so as to be vertically movable. The knob 8 is for fixing the holder 6 and the holder shaft 7 at appropriate vertical positions, and is provided at a position that does not protrude from both sides of the lip fence 4. The other end of the holder shaft 7 is rotatably fitted into a hole 18 provided in a base 17 at the upper part of the shaft 9. The holder shaft 7 and shaft 9 are fixed by a knob 10 screwed into the base 17. A spring 11 is attached to the shaft portion 19 of the shaft 9, and a roller holder 12 pressed by the spring 11 is fitted onto the shaft 9. The roller holder 1
2, a roller 14 is rotatably supported by a roller shaft 13. Further, a groove for fitting a key 15 is formed in the shaft portion 19 of the shaft 9, and by fitting the key 15 into the shaft portion 19 of the shaft 9,
The shaft 9 and roller holder 12 are prevented from rotating.

In the above configuration, the lip fence 4 is moved so that a groove can be formed at a predetermined position on the material 16, and the lip fence 4 is fixed to the guide bar 3 using the knob 5. Next, loosen the knob 8, rotate the holder shaft 7 so that the roller 14 is positioned almost directly above the grooving cutter 2, tighten the knob 8 at a position where the material 16 is appropriately pressed by the spring 11, and then tighten the holder shaft 7. The shaft 7 is fixed to the holder 6.
Next, the knob 10 is loosened, the guide surface of the lip fence 4 and the axial direction of the roller 14 are positioned at approximately right angles, and the knob 10 is tightened. Further, the material 16 is removed toward the front, the groove cutter 2 is raised to a predetermined height, and the material 16 is fed while being pressed against the guide surface of the lip fence 4 to perform cutting work. At this time, since the material 16 is pressed by the roller 14 via the spring 11, the material 16 does not flap, and the work can be carried out with peace of mind. In addition, since the material holding jig is installed on the top surface of the lip fence 4, when it is not in use, all you have to do is loosen the knob 8, rotate the material holding jig to the side of the lip fence 4 that is not in use, and fix it, which is very convenient. be.

[Effect of idea]

According to the present invention, since the material is pressed by a roller using a spring, there is no flapping or repulsion of the material, and cutting work can be carried out with peace of mind. Since it is installed on the wall, it can be rotated and easily removed from the work area when not in use.

Claims (1)

[Scope of utility model registration request] In a woodworking processing machine that protrudes a processing tool above the table and performs groove processing using a lip fence parallel to the tool as a guide, one end of a U-shaped holder shaft is attached to a holder fixed to the top surface of the lip fence so that it can rotate freely. A fixing means for fixing the holder shaft to the holder is provided at a position that does not protrude from both sides of the lip fence, and a pressing member is provided at the other end of the holder shaft, located horizontally to the table surface. 1. A material holding jig for a woodworking processing machine, characterized in that a roller is supported so as to be movable up and down.
