Description

[Detailed description of the invention] This invention prevents the risk of injury to hands, fingers, etc. due to rotation of the plane body when attaching or removing the fishing force, or adjusting the exposure amount of the cutting edge, and also prevents the risk of injury to hands, fingers, etc. when adjusting the cutting edge. This invention relates to a device for fixing a plane barrel in order to facilitate operations such as the following.

Conventionally, in the above-mentioned device, the plane body is fixed by engaging a stopper with an engagement spring energized in a retaining hole drilled in the end face of the plane body and a through hole formed in the side surface of the plane frame body. It is known that the plane barrel is fixed by fitting both ends of a linear stopper into engagement holes formed in the bottom surface of the plane frame and the side surface of the plane body.

However, with conventional devices that engage the stopper in the retaining hole, including the above device, the tip of the stopper and the bottom of the retaining hole do not come into contact, and the stopper is engaged in the middle of the retaining hole. Since the configuration is such that the stopper and the engagement hole, or the clearance created between the stopper and its holding part, rattling occurs. It is difficult to form the retaining holes with the same diameter, and even if it were possible to form the retaining holes with the same diameter, it would be difficult to determine the engagement position of the retaining hole and the stopper. It is unavoidable that looseness will occur in the fitting.

Therefore, when the plane barrel is fixed, the plane body will wobble, making it difficult to adjust the fishing force blade edge, and will also reduce the measurement accuracy of the exposed amount of the blade edge, which will have a negative impact on the fishing force installation, removal, and blade edge adjustment. There was a drawback of giving.

Therefore, as a result of studies in view of the above-mentioned drawbacks of the conventional methods, the present invention has been developed to create a plane that can easily determine the fitting position of the retaining hole and the stopper, tightly fit the two, and thereby fix the plane body without wobbling. The purpose is to provide a torso fixing device.

The drawings showing the embodiments of the present invention will be described in detail below.
In FIGS. 1 and 2, a front surface plate 2 is formed between a rear surface plate 1 and a front surface plate 2, which is provided so that its surface 2a can be adjusted with an adjustment shaft 3 relative to the surface 1a of the rear surface plate 1. Inside the cavity 4, a planer barrel 5 is rotatably supported by a bearing part 6 which is integral with the rear surface plate 1 so as to be driven and rotated by a motor 7. It is fixed via a presser foot 10 so that it can be attached and detached and the amount of exposure of the cutting edge can be adjusted.

Thus, the cutting edge of the fishing force 8 is placed on the one side end surface 5a of the plane body 5 and the bearing portion 6 opposite thereto, at a position where the cutting edge of the fishing force 8 is most exposed from the plate surfaces 2a, la of the front and rear surface plates 2, 1. An engaging hole 11 and a through hole 12 are formed at positions facing each other, and the through hole 12 is formed through the through hole 12, and the through hole 12 has a retaining part 13a at the outer end thereof, which is made of a rod-like member. Stopper 1 formed by bending
3 is elastically biased by a spring 14' to slide toward the plane body 5 side, and the tip thereof is rotatably engaged with the engagement hole 11 to fix the plane body 5. The retaining portion 13a is engaged with the stopper receiver 15 provided protruding from the outer wall surface of the bearing portion 6 by retracting the stopper 13 outward against the elastic force of the spring 4. The tip of the stopper is disengaged from the engagement hole 11 and is disposed so as to release the fixation of the plane barrel 5, and furthermore, the deepest part of the retaining hole 11 is provided in the conical hole 11a, and corresponds to the tapered surface of the conical hole 11a. Stopper 1
3 is provided in the tapered part 13b, and the tapered part 13b is elastically butt-fitted into the conical hole 11a by the spring 14, and the two are fitted concentrically and press-fitted without any play. It is configured so that

Here, the engaging hole 11 and the stopper 13 are provided to have the same diameter as possible, and the through hole 12 has a small diameter portion 12 a on the plane body 5 side.
On the outside, a spring receiver 16 is provided in a step shape on the large diameter portion 12b and has a diameter that allows rotation and sliding within the large diameter portion 12b, and is fixed to the stopper 13. The spring 14 is elastically biased against the stopper 13 by supporting both ends of the bearing cover 18 which is installed on the outer wall surface of the bearing part 6 with screws 17.

In addition, in the illustrated example, the stopper receiver 15 is made by bending a metal plate into an oval shape on the side, as shown in FIG.
The engaging recess 15b provided on the end face of the stopper 13 is provided so as to be able to hold the engaging part 13a of the stopper 13 so that it does not come off naturally, and is fixed to the outer surface of the bearing cover 18 by welding or the like. It is set up vertically.

In the above configuration, when cutting, the stopper 13 is pulled outward against the elastic force of the spring 14, and the retaining portion 13a is engaged with the engagement recess 15b of the stopper receiver 15, thereby removing the stopper. Since the tip of the knife 13 is kept out of the engagement hole 11 of the plane barrel 5, the plane barrel 5 is kept in a rotating state.

In the above state, when the engaging part 13a is removed from the stopper receiver 15, the stopper 13 is resiliently repelled by the spring 14 and moves toward the plane barrel 5, so the engagement hole 12 of the plane barrel 5 and the stopper 13 are made to face each other. As a result, the collar 13 is fitted into the engagement hole 12, and the plane barrel 5 is fixed.
Since they are in elastic contact with a, their tapered surfaces are pressed against each other, and the plane barrel 5 is fixed without wobbling.

As explained above, according to the plane barrel fixing device according to the present invention, the stopper 1 is elastically biased toward the plane barrel 5 side by the spring 14.
The taper 13b provided at the tip of the cutter 3 is butted against the conical portion 11a of the retaining hole 11 provided in the end face of the plane barrel 5, so that the tapered surfaces of the two are brought into pressure contact with each other. By tightly fitting the stopper 13 into the engagement hole 11, the plane barrel 5 can be fixed without wobbling, thereby making it possible to safely attach and detach the fishing force and adjust the exposure amount of the cutting edge. This can be done with high precision, and the tapered portion 13b facilitates positioning and fitting of the engagement hole 11 and the stopper 13. Therefore, the retaining hole 11 and the stopper 13 are made to have the same diameter to prevent rattling. Since it can be formed into a shape, the effect of preventing rattling can be further enhanced, and the above-mentioned positioning and fitting can be made easier.
