Abstract

PURPOSE: To enable a position of a cutter to be aligned with a marking line on an upper surface of a material to be worked in a short time. CONSTITUTION: A plate support member 36 is provided to a long hole part 30a of a fixed head 30, and a plate 37 coming in contact with a tip 26a and a rear end 26b of a blade 26 is fitted to a tip of the plate support member 36. Groove parts 36a, 36b with which a pin 38 is engaged at a position wherein a front face 37a or a rear face of the plate 37 conforms to a marking line 42 are formed on an outer periphery of the plate support member 36. The plate support member 36 is horizontally moved, and the pin 38 is pushed into the groove part 36b corresponding to a plane cutter 21 to fix a position of the plate 37. By making the plate 37 abut against the rear end 26b of the blade 26, the marking line 42 conforms to the rear end 26b of the blade 26.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter attachment position setting device for a woodworking router having a cutter for mortising a workpiece.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIG. Conventionally, in the cutter 121, a bolt 143 provided at the rear end of the cutter 121 is rotated to move back and forth, and the head of the bolt 143 is attached to the rotary shaft 124 by abutting the head of the bolt 143 against the side surface of the recess 124a of the rotary shaft 124.

When determining the position of the cutting edge of the cutter 121, the tip 126a or the rear end 126 of the blade 126 of the cutter 121 is used.
The length from b to the head of the bolt 143 is set to a specified value while measuring with a measuring tool, or the black wire 42 marked on the upper surface of the workpiece 41 and the tip 126a or the rear end 126b of the blade 126 are set. After the positions are matched with a measuring tool or the like and set, the cutter 121 is fixed to the rotary shaft 124 by the collet chuck 140.

[0004]

However, in the above method, if the position of the cutter 121 is not aligned, the rotary shaft 1 is replaced each time.
There is an inconvenience that the cutter 121 must be taken out of the 24 and the bolt 143 must be moved back and forth.
There is a problem that it takes a long time to align the blade edge of the blade with the black line 42.

An object of the present invention is to eliminate the above-mentioned problems of the prior art and to enable the position setting of the black line and the cutter marked on the upper surface of the work material to be performed in a short time.

[0006]

In order to achieve the above object, the present invention provides a woodworking lute machine having a head provided with a cutter for mortising on a vise for fixing a workpiece. Between the head and the plate support member, the head is provided with a plate support member that can rotate and move in parallel with the cutter, and a plate that determines the position of the cutter is provided at the tip of the plate support member. Further, a positioning means for positioning the plate at a predetermined position is provided.

[0007]

With the above construction, the cutter is arbitrarily inserted into the rotary shaft of the head, the plate support member is positioned at a predetermined position by the positioning means, and the cutter is moved in this state to move the cutter to the plate. Abut the front or rear edge of the blade. As a result, the black line marked on the upper surface of the workpiece fixed in place and the tip or rear end of the cutter can be aligned.
