Description

Early stage device for table saw

The present invention relates to an early stage device for a circular saw table, and more specifically, to a circular saw table that enables fast setting and release of the early rod through simple operation, and easy setting of various angles, and enables use in both left and right directions. It relates to the early detection device.

In general, plywood, MDF panel (Medium Density Fiber Panel), LPM panel (Low Pressure Melamine Panel), PB panel (Particle Board Panel), etc. are widely used for woodworking or construction. Accurate cutting is essential to use as

Thus, a circular saw table is mainly used for cutting the plate. In a conventional circular saw table, a rotary saw blade rotatable at high speed is installed on the upper surface of one side of a rectangular table formed in a predetermined size to protrude to a predetermined height, and one side of the table, That is, a guide rail for adjusting the position of the early stage is usually installed in the longitudinal direction of the table.

Therefore, when you want to cut a plate to a certain size using a circular saw table, first fix the position of the early stage based on the rotary saw blade according to the width of the plate to be cut, then place the plate to be cut on the table top to raise one end of the plate. If the plate material is pushed in the direction of the rotating saw blade rotating at high speed while in close contact with the reference surface of the plate material, the plate material can be cut to the desired size while the plate material is cut by the rotating saw blade.

On the other hand, the conventional early rod has a reference plane for cutting the plate on one side in the longitudinal direction, and a slider that moves precisely along the guide rail of the circular saw table is installed at one end, and the position of the slide is fixed on one side of the slider. Since the fixing means is provided, the position of the early stage can be arbitrarily adjusted and fixed on the top of the circular saw table according to the size of the plate to be cut.

However, the conventional early rod generally has a fixing means made of a rotary knob to fix the slider moving along the guide rail so that it does not move or to repeatedly rotate the fixing means to release the fixing of the slider. It has the disadvantage of being cumbersome and inconvenient to release.

In addition, the conventional early rod is provided with a fixing means on the slider installed at one end, so that the fixing force is exerted on the slider moving along the guide rail, so it can be used only on a circular saw table equipped with a guide rail, so there is a limitation in use. .

In addition, since the fixing force is exerted by the slider located at one end of the early rod, no separate fixing force is exerted on the other end of the early rod. There is a disadvantage of causing defects in cutting of

In addition, in the process of cutting the plate, if necessary, the plate is cut at a predetermined angle to cut the plate to a shape other than a square or a rectangle. As well as there is a disadvantage in that the resulting cost burden is increased, there is also the disadvantage that the use of an angle adjuster configured separately from the early stage is cumbersome and inconvenient.

In addition, since the reference plane for cutting of the board is generally formed only on the right side of the conventional early rod, when a right-handed person uses the early rod, the plate material to be cut is closely attached to the reference surface formed on the right side of the early rod, and then more force is applied to the right hand. Although there is no big inconvenience in moving the plate in a state in close contact with the reference plane, when left-handed people use the early rod, there is a disadvantage in that it is inconvenient to use because of the location of the reference plane located on the right side of the early rod.
