Description

Detailed Description of the Invention

  The present invention relates to a linear grinding jig for an electric circular saw, which is used to accurately grind wood into a straight line using an electric circular saw and to improve processing accuracy, dimensional accuracy and work efficiency.

  Conventional straight saws for electric circular saws use thread on the wooden board to be cut, and then move the blade of the electric circular saw along the line, or place an auxiliary ruler on the wooden board to be cut and its side The wood was applied to the side of the base of the electric circular saw.

Problems to be solved by the invention

This had the following drawbacks.
When the electric circular saw tries to grind the wooden board in a straight line in order to use the rotation of the motor, when the rotary blade of the circular saw first hits the wooden board, the end of the cut surface will be turned up due to the rotation shaking, machining accuracy and dimensions As accuracy deteriorated, high skill and skill were required to maintain a straight line due to the vibration of the motor and the vibration of the circular saw blade.
In addition, when an auxiliary ruler is used, a method of fixing the auxiliary ruler to the ground wooden board surface to grind the wooden board while moving the electric circular saw along the side of the auxiliary ruler, but to prevent the electric circular saw from sideways. However, since it has to be removed each time, the work efficiency is lowered and the size from the circular saw blade of the electric circular saw to the side of the pedestal differs depending on the manufacturer, so it is necessary to change the position of the auxiliary ruler each time. .

Means for solving the problem

Embodiments of the present invention will be described below.
A positioning guide ruler alignment scale (7) is provided on the main body base (2) made of metal or wood, and a positioning guide ruler slide groove (6) is provided. As shown in the sectional view of FIG. The positioning guide ruler (3) is inserted into the positioning guide ruler slide groove (6) using the positioning guide ruler adjustment nut (5) and the positioning guide ruler adjustment bolt (9). A replaceable circular saw blade guide plate (4) is mounted on the saw blade guide plate fixing groove (11), and the connecting square rod insertion groove (8) for connecting the linear grinding jig for the electric circular saw of the present invention is mounted. Was provided.
The present invention is a jig for linear grinding for an electric circular saw having the above-described configuration.

In order to solve the above-described problems of the prior art, the present invention is provided with a positioning guide ruler alignment scale (7) and a positioning guide ruler slide (6) on the main body base (2), and an electric circular saw slide in the groove. The positioning guide ruler adjustment nut (5) and the positioning guide ruler adjustment bolt (9) are rotated to tighten or loosen the positioning guide ruler adjustment nut (5) provided with the guide groove (13). It is possible to move and fix at any position within the groove range, and replace the circular saw blade guide plate fixing groove (11) provided on the side of the main body base (2) to improve dimensional accuracy and machining accuracy. A connection for connecting the straight grinding jig (1) for the electric circular saw of the present invention so that the wooden circular saw blade guide plate (4) can be mounted and can be used for a long work material. Square rod insertion Grooves provided (8) and fixable wearing the connecting angle bar (12) in the groove.
When the present invention is used in the structure as described above, the electric circular saw fixed base (C) from the surface (B1) of the circular saw blade guide plate of the circular saw blade (B) of the electric circular saw (A). Measure the dimensions up to the surface (C1) per positioning guide ruler on the positioning guide ruler (3) using the positioning guide ruler alignment scale (7) with the positioning guide ruler adjustment nut (5) loosened. The positioning guide ruler (3) is fixed at regular intervals via a locking washer (10) by moving to the position and tightening the adjustment nut.
The linear saw jig (1) for the electric circular saw that has been adjusted as described above is aligned with the side of the circular saw blade guide plate (4) at the marking position on the upper surface of the work material (D), and the electric circular saw (A) is moved to the electric circular saw. Place on the straight saw jig for saw (1), and place the surface (C1) of the positioning guide ruler of the electric circular saw (A) along the side of the positioning guide ruler (3) as shown in the schematic diagram of FIG. It is possible to process the material accurately and quickly just by moving (A). Furthermore, as a means to improve work efficiency and dimensional accuracy, the surface of the positioning guide ruler located on the electric circular saw fixed base (C) An electric circular saw slide guide groove (13) provided in the positioning guide ruler (3) in (C1), a removable electric circular saw slide guide rail (14) for fitting into a guide rail mounting nut (15) and a guide rail Mounting bolt Hold (16) and attach.

The invention's effect

As described above, according to the present invention, the circular saw that is in contact with the circular saw blade guide plate (4) only by moving the electric circular saw (A) on the linear saw jig (1) for the electric circular saw. Since the blade (B) moves in a stable state, the processing accuracy and dimensional accuracy are improved without turning up the end of the cut surface, and the circular saw blade guide plate (4) using wood can be replaced. As a result, the circular saw blade guide plate (4) can be easily changed not only by straight grinding but also by cutting the work material (D) at an angle.
By providing positioning guide ruler (3) and circular saw blade guide plate (4), it can be applied to electric circular saws (A) of any size. The material can be processed accurately and quickly without the need for the process.
Further, the electric circular saw slide guide rail (14) is fitted into the electric circular saw slide guide groove (13) provided on the positioning guide ruler (3), and the electric circular saw (A) is moved, thereby further improving the work efficiency. In addition, the dimensional accuracy can be increased.
