DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woodworking apparatus for producing various woodworking products, and more particularly to finished products such as tea cups, wooden plates, round trays, confectionery, tea bowls, tea chests, salad balls, and the like. Is the most suitable woodworking equipment for making woodwork products such as discs or cylinders.

[0002]

2. Description of the Related Art Conventionally, the above-mentioned woodworking products are manufactured by:
For example, in most cases, a material is fixed to a rotating shaft of a lathe or the like, and a cutting tool is pressed against the material to form a shape. However, this working method requires a great deal of skill in the work and is not suitable for mass production of the same product, and also has a drawback that so-called "loss" is generated frequently and the cost is eventually increased.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention proposes a woodworking apparatus designed so that anyone can easily produce large quantities of woodwork products such as discs and bowls without any skill. .

[0004]

SUMMARY OF THE INVENTION The present invention comprises a frame, a processing table which is horizontal with respect to the frame, a rotation and vertical movement shaft provided on the frame, and a chuck provided at an end of the frame. Use a processing device such as a drilling machine.

A feature of the present invention is a pair of columns provided on both sides of the table, a cylinder and a piston shaft provided with the columns, and a bridge provided at the end of the piston shaft.
And a holding plate provided with an opening larger than the outer diameter of the product made at the center thereof, and the chuck includes:
It is provided with a pair of cutters which are attached to the vertical drive shaft and process both front and back surfaces of the product.

[0006] One of the above-mentioned cutters, for example, a cutter on the surface is fixed to a chuck of a vertical moving shaft in advance. Subsequently, a flat material is placed on the table, and the vertical moving shaft is lowered. As a result, the pressing plate fixes the material on the table.
Here, when one of the cutters is lowered while being rotated, the cutter passes through the opening of the holding plate to form a circular recess on one surface of the material.

Next, when the processing of one side is completed, the presser plate is raised, the material is inverted, and the presser plate is lowered again and fixed on the table. On the other hand, another cutter, for example, a back cutter is fixed to the vertical moving shaft, and the lower surface of the material can be processed as a result of lowering the cutter, so that a woodwork product can be easily manufactured.

[0008] The pair of cutters for processing the front and back surfaces are “substantially inverted T-shaped” and “substantially T-shaped”, respectively.
The vertical portion is constituted by a rotating shaft and a flat cutter blade at the end thereof. By rotating the cutter, a disc-shaped product is obtained. So each cutter,
Since it is flat, there is an advantage that it can be easily processed and polished when worn.

At this time, it is natural that the surface processing and the rear surface processing must be performed at the same position in the vertical direction. For this reason, the present invention is provided with a guide rod which can fit the concave part and the upper end of the product to be manufactured, and the end of the guide rod can be fitted in a hole provided in the center of the table. It is.

After forming a circular recess on one side of the above material, the holding plate is raised to take out the material, and a guide rod is fitted into a hole provided at the center of the table. After that, the material is turned over and the unprocessed surface is defined as the surface. At this time, the back surface of the material is already processed on one side of a product having a circular depression, and the head of the guide rod is fitted into this depression. As a result, both the front and back surfaces are always performed at the same position in the vertical direction.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a case where a tea ceremony is made as an embodiment of the present invention. FIG. 1 shows a conventional drilling machine, (1) is a vertical frame, and (2) is an intermediate frame. (3) is a rotary and vertical drive mechanism provided on the axis of the frame (1) above the table (2), and (4) is a vertical movement thereof. The operation handle (6) is a chuck provided at the end of the rotation and vertical movement shaft (5).

A pair of columns (7) are provided on both sides of the table (2), and cylinders (8) for hydraulic pressure and the like are vertically mounted above the pair of columns (7). This cylinder (8)
A piston shaft (9) is provided on the lower surface of the piston so as to protrude downward, and a horizontal pressing plate (10) is bridged to the end of each piston shaft (9). An opening (11) is provided which is larger than the outer diameter of the product to be manufactured.

A center portion of the table (2) is provided with a "T" -shaped hole (12). A guide rod having a "T" -shaped cross section as shown in FIG. (13) can be fitted. In this case, the head of the guide rod (13) is located above the table (2).
At this time, it is important that the outer diameter of the guide rod (13) is the same as the diameter of the hollow at the center of the surface of the tea tray to be manufactured.

FIGS. 2 and 3 show a surface cutter (1) attached to a vertical movement shaft (5) by the chuck (6).
4) and a backside cutter (15). These front and back cutters (14) and (15) are "substantially inverted T-shaped" and "substantially T-shaped", respectively, and the vertical portions are the rotation shafts (16) and (17). Cutter blades (18) and (19).

As shown in FIG. 6, a cutter blade (18) for forming a surface is provided with a convex portion (2) for forming a depression (C) at the center of a tea tray (B).
0) is provided at the center of the lower surface, whereas the center of the upper surface of the cutter blade (19) for forming the back surface is provided with an annular projection (D) at the center of the back surface of the tea tray (B). A groove (21) has been drilled.

First, the rotating shaft (16) of the surface cutter (14) is fixed to the vertical moving shaft (5) by the chuck (6). Subsequently, a flat wood material (A) is placed on the table (2). In this case, the thickness of the material (A) is slightly larger than the thickness of the tea cup to be processed. Then cylinder (8)
As a result, the pressure plate (10) is lowered to fix the material (A) between the tables. Here, the drive mechanism (3) is driven to turn the handle (4).

As a result, the vertical moving shaft (5) and the surface cutter (14) descend while rotating, and pass through the opening (11) of the holding plate (10) to the material (A) to form the surface shape of the tea stool. The dent is machined. At this time, a circular dent (C) is formed by the projection (20) of the cutter blade (18).
In this operation, it is preferable that the depression of the surface shape is manufactured in the same operation at several places according to the size of the material.

Next, the cylinder (8) is raised again to remove the material (A) from the table (2). After that,
The guide rod (13) is fitted into the hole (12) of the table (2). At this time, the head of the guide rod (13) protrudes above the table (2). In this state, the material (A) is turned over, and the head of the guide rod (13) is fitted into the recess (C) already processed on one side thereof. Is easily and reliably performed.

Subsequently, in the same manner as in the case of processing the front surface, the cutter blade is changed to the cutter blade (15) for processing the back surface, the holding plate (10) is lowered to press the material, and the back surface is processed in the same manner as described above. A tea cup as shown in FIG. 6 can be easily manufactured.

【The invention's effect】

As described above, the present invention enables anyone to easily produce large quantities of wood products such as discs and bowls without any skill.
