Abstract

(57) [Abstract] (With correction) [Problem] To enable a round shed material having a non-uniform shape to be cut and used for a timber construction method of a wooden building. The processing machine includes an auxiliary base that can be moved to the front side or the rear side of a main body base, and a center of a cutting cutter provided on an upper part of the main body base is arranged at a processing position of a processing material within a movement range of the main body base. In a state where the work cannot be performed, the auxiliary base is used to secure a fastening and fixing position with respect to the work material, so that the center of the cutting cutter can be arranged at the work position of the work material.

Description

[Detailed description of the invention] [Purpose] The present invention relates to mortise processing of pillars as pillars, which are structural materials by a timber construction method of wooden construction, which has been known since ancient times in Japan, and to work for feet of pillars.

For the tenon machined at both ends of the pillar, the structural materials of the girder, purlin, beam, and climbing beam, which are related to the base, girder, purlin, beam, and climbing beam, are all called hut materials. The framing method is divided into a method in which all hut materials are used with square materials, and a method in which all hut materials are used with round materials.

For the processing of hut materials, a reference point called water is set, and the height of the girder, purlin, beam, and climbing beam is determined from the reference point. Form the roof of the building. When using square materials, the width and thickness of the timber are determined uniformly, so the positional relationship between the hut materials is always horizontal, so the length of the bundle and the combination of each timber can be easily calculated and processed. Since it is only necessary to machine a mortise, it can be easily machined with a commercially available corner only machine or a chain chisel machine.

When using round materials, natural or partially lumbered wood is used, so the shape and size of each piece of wood will be different. It is necessary to process the mortise first horizontally for the inclination generated due to the difference in the size and shape of each hut material. In addition, the processing of the feet and pillars does not come to the center of the processed material, it is always several centimeters above and below the water, several centimeters from the center, and the difference in the size of each wood is 30 centimeters. In some cases, this requires the use of a large base and a large vise to secure the machine to the workpiece, making it impossible to machine with commercially available corner-only machines and chain-chin machines.

 [Problem to be solved by the invention] Place the machine on the top of the ink drawn on the round material of different sizes and shapes as described above, and tighten the work piece from below using the fastening vise provided at the bottom of the machine. By fixing the machine, the ink written on the work material is easy to see, the alignment and the operation of the machine are easy, and it is the best method for fixing a small machine to a large work material.

However, there are several problems. The first is that the base must be reduced in size a little because of the weight. The second is the large difference in the thickness of each processed material. The feeding amount of the provided wood tightening screw increases each time the work material changes, increasing the burden on the worker and deteriorating the workability. Third, the tightening force of the vise part with respect to the base part increases the work material. The fourth point is that the base part may not move during fine adjustment of ink alignment after fixing the machine, and the fourth point is that the work material is surrounded by the shaft connecting the base part and the vise part of the machine, The machine must be attached and detached while tilting the machine forward from a small gap in the front of the machine.

The present invention focuses on the above problems.

[Means for Solving the Problems] In order to solve the above problems, the present invention solves each problem as follows.

The first point is to reduce the size and weight of the base by providing an independent auxiliary base that can be moved behind the main base. By fixing the machine and fixing the machine, it is possible to cut the processing position.

The second problem with the feed amount of the tightening screw provided in the vise is that the position of the fulcrum of the clamp bar related to the tightening screw is moved, and the work holding metal provided at the tip of the clamp bar and the crank bar Since the movement of the thread is inversely proportional, if the difference in the size of the workpiece is large, the position of the fulcrum of the crank bar is moved toward the thread and the movement of the clamp bar is set to the maximum inverse proportion. By maximizing the movement of the work material holding bracket, the burden on the operator can be reduced and the work can be performed quickly.

The third problem is that when the machine is fixed to the work material, the tightening force of the vise from below is applied to the base used, making it difficult to make fine adjustment movements of the base. By mounting a plurality of rollers 1 to 2 mm below the bottom surface of each base to the contacting parts and attaching to both ends of the base, the tightening force is directly applied to the rollers, and the rotation of the rollers reduces the movement of the base.

The fourth problem is that the work material is enclosed by the base, vise and shaft of the machine, and the machine can only be attached to and detached from the work material through the gap on the front of the machine. By turning the vise part 90 degrees in the longitudinal direction of the work material, the members provided at the bottom of the machine are temporarily released to create a space at the bottom of the machine. So that it can be lifted to the top surface.

By the above means, each problem was solved, and small and lightweight mortises of small timber such as pillars and mortars and pillars were machined safely and accurately.

 [Embodiment] An embodiment of the method for cutting a round / square bar mortar according to the present invention will be described below. 1 and 2 are views showing a state in which a machine is fixed to a workpiece and a processing position is secured, and FIG. 1 shows that three movable parts can be moved with respect to a processing part 7 located at an end of a workpiece 6. The figure shows a state in which the auxiliary base is arranged at the center of the work material 6 and the machine body 1 is fixed at the vice 4. FIG. 2 shows a state in which a main body base 2 is arranged for a processing portion 7 located at the center of a processing material 6 and a processing machine main body 1 is fixed to a processing material 6 with a vice portion 4. The main and auxiliary bases 2 and 3 have the purpose of receiving the tightening force of the vice section related to the used base when the machine is fixed, and lightening the movement of the base used for fine adjustment. A plurality of 2A and 3A rollers are attached to both sides of the base. A 4V vice is provided with 4A tightening screws, 4B clamp bars, and 4C material tightening parts. 5 is a machine main body. The connection shaft 8 of the vice portion is a cutter blade for cutting.

FIGS. 3 and 4 are detailed views of the vise portion, and FIG. 3 shows each member combination of the vise portion. A plurality of pin holes a are installed in the 4B crank bar, and the pin holes are moved to the tightening screw 4A side. The clamp bar is pushed up by feeding the screw, and the clamp bar is pulled down by returning the screw. At this time, the movement of the clamp bar screw side and the movement of the 4C material tightening bracket side provided at the tip of the crank bar are 4A. Movement by several times the screw feed amount enables tightening and retightening of the work material with small screw feed from large to small material. Fig. 4 shows the difference in the movement of the clamp bar by moving the fulcrum position. FIG.
