Description

The utility model relates to the field of construction, rural construction and, in particular, can be used for construction work in regions remote from stationary sawmills.

There is a known problem of the lack of tools for building a wooden house from logs, for example, for creating flat bases on a log.

Known longitudinally milling woodworking machine containing a bed with two guides, a carriage with the possibility of longitudinal movement, on which is mounted a tool head with a drive, a table for the workpiece, see RU 2040390, cl. B27C 9/04 publ. 07/25/1995.

However, a well-known machine tool is a complex and expensive facility and cannot be used in small towns and villages.

The aim of the creation of the claimed invention is to achieve a technical result to simplify and cheapen the cutting system of flat surfaces and provide the ability to create flat surfaces with a hand tool.

The specified technical result is achieved by the fact that in the known system, on the working end of the electric drive (drill), on both sides of the axis of symmetry of the future plane there are two vertically mounted guide wheels, and on the output axis of the electric drive through the gear, horizontally, a circular saw is installed, in addition , the gear transmission is made in the form of two bevel gears, the shaft of one of the gears is connected to an electric drive (drill), and the shaft of the second gear connected to it is connected to a circular saw, flat be is oriented horizontally.

The utility model is illustrated by graphic materials. In FIG. 1 shows a general view of the structure of the saw; FIG. 2 shows a kinematic diagram. The structure shown in FIG. 1 and 2 has the following notation:

1. drill;

2. steering wheels

3. the first bevel gear;

4. the second bevel gear;

5. circular saw;

6. center line;

7. Guide line for wheels.

The utility model consists of an electric drill 1, in front of which two vertical guide wheels 2 are mounted in front. The drill is connected to two bevel gears 3, 4. The first bevel gear 3 is fixed in the drill 1. The second bevel gear 4 is connected to it, on which shaft is fixed horizontally oriented circular saw 5.

With the tool work as follows.

The log is fixed on the table or in the goats and draw a direct guide line on its surface. Then half the distance between the guide wheels 2 of the tool is measured from this line and two reference lines are drawn for their movement.

Given that the user will move the circular saw 5 forward, and if a drill is used as an electric drive, its handle will restrict movement, therefore, to work with an electric drill 1, it should be turned 180 °. In the same position, the guide wheels 2 are attached to the drills 1. Then, the shaft of the first bevel gear 3, which is in contact with the second bevel gear 4, is fixed in the drills 1, and the wheels 2 are mounted on the guide lines 7. Thus, due to the structural arrangement of the lower points wheels 2 and a circular saw in one horizontal plane 6, the latter is installed horizontally and at a certain depth of cut of the tree. After that, turn on the drill 1 and advance the saw into the trunk of the log.

Given that the cut piece of wood during the advancement of the saw 5 will rest against the drill 1, then the cut piece should be broken off and removed periodically.

The claimed utility model is new, previously unknown, which indicates its compliance with the criterion - novelty.

The design of the utility model can be made in rural conditions using improvised materials, which indicates its compliance with the patentability criterion - industrial applicability.
