る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric router, and more particularly to a motor housing having a cylindrical body, a base having a cylindrical housing grip that fits into the body of the housing, and a combination of the base and the housing. In the electric router, the electric router is provided with a locking means for integrally tightening the base and the housing in a desired positional relationship, and a cutter protruding from the base surface and driven by the motor. This invention relates to an improvement in a mechanism for adjusting the amount of protrusion of a cutter.

をひき起こす。 In conventional electric routers of this type, the locking means is loosened so that the body of the housing can slide within the housing gripping part of the base, and the body is slid as appropriate to achieve the desired positional relationship, that is, the desired amount of blade protrusion. At this point, the locking means was tightened to obtain the desired protruding state of the knife. A feature of such a conventional device is that it can be adjusted in a short time, but it has the disadvantage that the accuracy of the protrusion amount of the blade is poor because the adjustment is made by visual estimation. This causes a problem in that the accuracy of cutting depth becomes less or less accurate when using an electric router.

量ｈ分だけ被削材を切削する。 The component configuration of the electric router according to the present invention is as follows. A housing 2 having a cylindrical body 20 containing a motor is provided. A male thread 22 is formed in the body portion 20 of the housing 2 . Also provided is a base 3 having a housing gripping portion 30 that fits into the body portion 20 of the housing 2 and grips the housing 2. Fixing of the housing 2 and the base 3 is achieved by tightening the locking means 4 consisting of a bolt 40 and a nut 42 to narrow the slit 32 of the base 3, thereby reducing the inner peripheral diameter of the housing gripping portion 30 of the base 3. The rotary blade 6 protruding from the base surface (lower surface) 34 of the base 3 is fixed to the motor shaft 9 and rotates to cut the workpiece by an amount h of protrusion from the base surface 34.

0 is housed in a relationship that allows rotation but prevents axial movement, and the female thread 70 of the ring 7 is
The male screw 22 of the housing is assembled into the housing.
A wave spring 8 is interposed between the base 3 and the ring 7, and the spring 8 causes the ring 7 to
is pressed away from the core of the body 20 of the housing 2, and a portion of the female screw 70 of the ring 7 and a portion of the male screw 22 of the housing 2 are pressed into engagement with each other.

手動させることにより実現できる。 Next, the operation of adjusting the protrusion amount, that is, the depth of cut, of the blade in the electric router according to the present invention will be explained. First, when performing coarse adjustment (see Figure 4), lock means 4
Loosen the bolt 40 and remove the slit 32 of the base 3.
In the state in which the inner circumferential diameter of the housing gripping part 30 is widened, the ring 7 exposed from the base 3 is pressed against the biasing direction of the spring 8 (in the direction of arrow B in FIG. 4). Ring 7 and housing 2
This can be achieved by manually moving the base 3 (or housing 2) up and down by disengaging the screws 22 and 70.

ング２が上下へねじ送りされ微調整ができる。 For fine adjustment (see Figure 3), the bolt 40 of the locking means 4 is loosened in the same way as for coarse adjustment, and the ring 7 exposed from the base 3 is rotated (see the arrow in Figure 3). C direction)
As a result, the ring 7 is pressed by the spring 8.
Since the screws 22 and 70 of the housing 2 are partially engaged with each other, the housing 2 can be screwed up and down in accordance with the amount of rotation of the ring 7, allowing fine adjustment.
