Description

[Detailed Description of the Invention] The present invention relates to a cutting stopper mechanism for a router, large cutting machine, dovetail groove processing machine, etc.

For example, when machining a large cut B, a large cut C, etc. on a workpiece a as shown in Fig. 1 using the above-mentioned router, fire cutter, dovetail groove processing machine, etc., the cut with a bit is made in advance. By providing a stopper mechanism that regulates the depth, it is possible to precisely process the large insert b, large insert hook C, etc. to a desired depth.

Conventionally, various types of stopper mechanisms have been known as the above-mentioned stopper mechanisms, but all of the current ones can only adjust the height in one step, so for example, the stopper mechanism shown in Fig. 1 cannot be adjusted in height. When machining dovetail C, if the depth of cut differs between large cut C' and dovetail C'', the height of the stopper must be adjusted each time, making the operation complicated and troublesome. It had the disadvantage of being inefficient.

Therefore, as a result of consideration in view of the above-mentioned drawbacks of the conventional technology, the present invention was developed as follows:
By configuring the machine so that it can be stopped in stages, it is possible to perform machining with different depths of cut, such as large cutting, large cutting, or dovetail grooves, with a single touch, and to freely adjust the depth of each cut. A stopper mechanism for this purpose was obtained.

The present invention will be explained in detail below based on the drawings showing an embodiment of the large-scale processing machine.

First, the processing machine is composed of a processing machine main body 1 and a support body 2, as shown in FIGS. 2 and 3.

As shown in FIG. 2, the processing machine main body 1 is driven by a motor case 3 in which a motor 4 and a blade arbor 5 are coupled together by a motor shaft 4a and a power transmission mechanism 6 such as a winding or gear. Collet chucks 7 are mounted on each of the outwardly protruding ends.
A flat bit 8 and a dovetail bit 9 are removably attached.

In addition, a stopper body 10 is mounted on one side of the motor case 3, parallel to the axis of the blade arbor 5, and rotates into a hole 11 formed through the center of the side wall of the motor case 3 in a direction perpendicular to the blade arbor 5. Center bolt 1 that freely penetrates

On the outside of the above-mentioned front and rear guide bar 18.18, a side play (20.20) is installed parallel to the above-mentioned front and rear guide bar 18.18 so as to be flush with the contact surface of the workpiece 21.
Furthermore, the end of the longitudinal feed screw rod 23 with a handle 23a is rotatably supported by the vise 16 and the support 17, preventing movement in the axial direction. Screw the front and rear sliding bases 19 together,
The front and back sliding base 19 is rotated by the rotation of the handle 23a.
The left and right sliding base 23 is slidably fitted to the left and right guide bars 25 installed on the front and back sliding base 19, and the left and right sliding base 23 is screwed into In addition, a handle 26 and a left and right feed screw rod 26 with an a are supported on the front and rear sliding base 19 so as to be rotatable while preventing axial movement.
3 is movable in the left-right direction; and a clamp mechanism 29 in which a clamp plate 28 is supported on the support 17 so as to be movable in the front-back direction by operating the handle 27.
It is a form of formality that these are provided respectively.

Thus, the processing machine main body 1 is rotatably supported by the left and right sliding base 23 of the support body 2 by the center bolt 12 and with the vertical feeding means 30 interposed therebetween.

That is, as clearly shown in FIG. 2, vertical grooves 31 are provided in the side walls of the left and right sliding base 23, and the stopper body 10 is fitted therein so as to be movable up and down, and a knob 33 is fixed to the center bolt 12. The left and right sliding base 23 is assembled by screwing together the tightening screw 32.

The processing machine main body 1 is fixed to the support body 2, and the tightening nut 34 is loosened, and after it comes into frictional contact with the knob 33, it is further loosened to tighten the tightening screw 32 and the center bolt 12. By unraveling, the processing machine main body 1 can be rotated with respect to the support stand 2.

In addition, two lock bolts 35 and 35 are attached to the side wall of the processing machine body 1 and the stopper body 10, as shown in FIGS. 2 and 4.
', two microswitches 36.3g, and a lock plate 37 with a limit lever 38 are provided, respectively.
By rotating (180 degrees) to selectively use the lock plate 37, the lock plate 37 hits the lock bolt 35 or 35' and stops at the respective position, and at this time the micro switch 36 or 36' and the limit lever 38 are activated. Contact.

In this case, when the processing machine main body 1 is rotating, even if the push button 39 provided on the motor case 3 is turned on, the motor 4 and the field 4' are not energized.

Next, when the lock plate 37 hits the lock bolt 36 and stops, one of the micro switches 36 and 36' is turned on by the limit lever 38, so the push button 3 is turned on.
By turning on 9, the motor 4 rotates.

Now, assuming that the motor 4 rotates in the forward direction when the microswitch 36 is turned on, the motor 4 rotates in the reverse direction when the microswitch 36' is turned on.

In this way, when either the flat bit 8 or the dovetail bit 9 is used, it is rotated in the normal direction when in use.

Further, the above-mentioned vertical feeding means 30 moves the above-mentioned stopper body 1°,
A vertical feed screw rod 40 with a handle 40a is installed vertically so as to be freely rotatable while preventing movement in the axial direction, and is screwed into the screw hole 23b of the left and right sliding base 23 to form the handle 40.
By rotation a, the processing machine main body 1 can be moved up and down in the axial direction of the blade arbor 5 with respect to the support body 2.

In this way, with the workpiece 21 clamped to the support 2, the main body of the processing machine is lowered by the vertical feed means 30 and the bit is used to process large-scale cuts, etc.
A stopper mechanism 4 is provided to enable machining of large inserts etc. to a desired depth.

In this case, the stopper mechanism 41 has the above-mentioned stopper body 1 that moves up and down together with the processing machine main body 1, as shown in FIG.
A through hole or notch 4 is formed in the horizontal part 10a of 0 in the vertical direction.
2, and a stopper plate 4 that can freely open and close the through hole 42.
3 is pivotally connected with a rivet or the like, while the through hole 42
A screw hole is provided at a suitable location of the support body 2, that is, on the upper surface of the left and right sliding base 23, so as to face coaxially with the screw hole, and an adjustment nut 46 is interposed in the screw hole so as to have a diameter larger than the inner diameter of the through hole 42. A first stopper 45 made of a bolt or the like is screwed in such a way that its height can be adjusted freely, and the head 48 a is inserted into a screw hole 47 opened at the upper end of the first stopper 45 from the inner diameter of the through hole 42 . A second stopper 48, which is provided with a small diameter, is height-adjustable through an adjustment nut 49 and screwed together coaxially, and when the through hole 42 is closed by the stopper plate 43, the fifth As shown in the figure, the second stopper 48 abuts against the stopper plate 43 and becomes a stopper, and when the through hole 42 is opened by the stopper plate 43, the first stopper 45 is moved as shown in Figure A. It is configured to abut against the opening edge of the through hole 42 and act as a stopper in two stages.

In the above configuration, the downward stroke of the processing machine main body 1 with respect to the support body 2 is large as shown in FIG.
The stroke shown in the figure is smaller than that, and the stroke can be adjusted by further adjusting the heights of the first stopper 45 and the second stopper 48.

Therefore, as shown in FIG. 1, for example, when machining a large cut b on a workpiece, it is necessary to adjust the height of the second stopper 48 in advance in accordance with the depth of the large cut to be machined. often,
Also, when machining a large dovetail hook C, adjust the heights of the first and second stoppers 45 and 48 to correspond to the depth of the large dovetail C' and the depth of the dovetail c'' to be machined in advance. Keep it
First, with the through hole 42 closed by the stopper plate 43, the vertical feed means 30 is operated to process a large cut C'.Then, the through hole 42 is opened and the vertical feed means 30 is operated to lower the processing machine body 1. It is possible to process the armrest C”.

At this time, according to the illustrated example, the large input C is made by ten bits 8.
After machining ', the main body 1 of the processing machine is rotated 180 degrees and the dovetail C" is machined using the dovetail bit 9.

Note that the processing machine of the present invention is not limited to the above-mentioned embodiment, but may also be a router in which the bit moves up and down with respect to the support 2 by at least the vertical feed means 30 to cut the workpiece 21. 1 and other similar processing machines.

As explained above, according to the cut stopper mechanism for routers and other processing machines according to the present invention, the processing machine main body 1 is moved up and down with respect to the support 2 by the vertical feed means 30, and the bit 8 or 9 is used to In a processing machine configured to cut a material 21, the cutting stopper mechanism 41 is configured to open and close a through hole etc. 42 provided in the stopper body 10 using a stopper plate 43, thereby allowing the first stopper 45 and the second stopper 48 to be connected to each other. so that it can be stopped in two stages by
Katsumata 1st. Since the heights of the second stoppers 45 and 48 are adjustable, the heights of the second stoppers 45 and 48 are adjusted in advance.
If the heights of both stoppers 45.4B are adjusted, the depth of cut by the bits 8 and 9 can be made in two stages simply by opening and closing the through hole 42 with the stopper plate 43. Therefore, for example, Even when the depth of cut is different, such as when cutting with a large depth of cut, there is no need to adjust the height of the stopper midway, and it is easy to perform large cuts with a preset depth of cut. This has the effect of making it easy, efficient, and highly accurate to process.

Also, 1st. Since the height of each of the second stoppers 45 and 48 can be adjusted independently, the height can be adjusted over a wider range by adjusting the height of each, and the depth of cut can be adjusted over a wide range in multiple stages. In addition, the stopper mechanism 41
The stopper plate 43 and the first . Since the structure can be easily formed from the second stoppers 45 and 48, it can be manufactured at low cost.
