An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view of a slide type cutting machine according to the present invention, FIG. 2 is a plan view in a state after cutting, and FIG. 3 is a front view. In FIG. 1, reference numeral 1 denotes a base, and the base 1 is fixed to the ground (floor) or the like because the slide type cutting machine is a stationary type. Also base 1
A holding member 2 is provided at a rear portion (right side in the figure) of the upper surface of the. The holding member 2 is provided with a slide shaft 4 via bearings 3 and 3 so as to be movable in the axial direction. The slide shaft 4 is covered by a casing 5,
This casing 5 is also configured to move in the axial direction of the slide shaft 4 together with the slide shaft 4. A holding plate 6 is fixed to a front portion (left portion in the drawing) of the casing 5, and a swing arm 8 is provided on the holding plate 6 via a support shaft 7 so as to be swingable. The swing arm 8 is provided with a casing 9 for housing a motor (not shown), and a circular saw blade 10 is rotatably supported. The circular saw blade 10 is configured to be rotated by the rotation of a motor shaft (not shown) of the motor being transmitted through a gear. A handle 11 is fixed to the swing arm 8, and a roller 13 is held on the handle 11 via a support member 12. The swing arm 8 is provided with a safety cover 31 that can rotate coaxially with the circular saw blade 10.

On the other hand, a table 1a is provided on the left side of the base 1 in FIG. 1, and a support member 14 is provided on a front side surface of the table 1a, and a through hole 14a of the support member 14 is provided.
Is provided with a shaft 15 so as to be movable in the axial direction. The shaft 15 is configured so that the movement is restricted by a fixing bolt 16 provided on the support member 14. One end of a rail 18 is pivotally connected via a pin 17 to the upper end of the shaft 15 in the drawing. A support member 19 is provided at an appropriate position on the upper surface of the base 1, and a shaft 20 is provided in a through hole 19a of the support member 19 so as to be movable in the axial direction. The movement of the shaft 20 is restricted by a fixing bolt 21 provided on the support member 19. And rail 18
A long hole 18a is formed in the other end of the shaft 20 in the axial direction, and is fixed to the upper end of the shaft 20 by a positioning bolt 22 in a position-adjustable state. The shafts 15 and 20 are provided with scales 15a and 20a, respectively.
It is configured so that it can be easily positioned at a desired position.

FIG. 4 is a view for explaining an engagement state of the roller 13 with the rail 18. That is, the rail 18 has a U-shaped cross section, and holes 18 having a width slightly larger than the outer diameter of the roller 13 are provided at two positions in the front-rear direction of the upper plate member 18b.
c, 18c are formed. At the time of cutting, the roller 13 is inserted through one of the holes 18c, and the rail 1 is inserted.
While being moved along 8, it is configured to be cut and removed upward from the other hole 18c.

[0009] The operation of the slide cutting machine thus configured will be described below. First, in the case of performing horizontal cutting, in FIG. 1, the fixing bolts 16 and 21 are loosened, and the height positions of the shafts 15 and 20 are positioned and fixed with reference to the scales 15a and 20a. The bolt 16 and the fixing bolt 21 are fastened to position the shaft 15 and the shaft 20. Further, the workpiece 23 is placed on the table 1a. In this state, a motor (not shown) is driven to rotate the circular saw blade 10 and rotate the swing arm 8 about the support shaft 7 in a counterclockwise direction in the figure. At this time, the swing arm 8 is
4 (see FIG. 5), the swing arm 8 is urged in the clockwise direction about the support shaft 7 in the drawing, so that the swing arm 8 is rotated counterclockwise against the urging force of the spring 24. Becomes The roller 13 is inserted from the hole 18c of the rail 18 by the rotation of the swing arm 8, and the roller 13 is
8 is engaged. FIG. 5 is a diagram showing the state at this time.

Further, from the state shown in FIG. 5, the operator grips the handle 11 and moves the circular saw blade 10 rightward in the figure. During this movement, since the roller 13 is engaged with the rail 18, the urging force of the spring 24 is received by the plate 18 b on the upper side of the rail 18.
No extra force is required without receiving the urging force of No. 4 and comfortable work can be performed. During the cutting operation, the slide shaft 4 slides with the casing 5 with respect to the bearing 3. Then, by the movement of the circular saw blade 10, a desired press-cutting operation of the workpiece 23 is performed. FIG. 6 is a diagram showing the end state of the cutting operation.

The roller 13 is connected to the plate 1 of the rail 18.
8b, the roller 13 is released from engagement with the rail 18 and the handle 11 is moved to the left in the figure to return to the initial state (FIG. 1).

Next, the operation in the case of performing inclined groove cutting or the like will be described below. In this case, in FIG. 7, the fixing bolts 16, the fixing bolts 21, and the positioning bolts 22 are loosened, and the shafts 15 and 20 are moved in the axial direction so as to have a desired height and a desired inclination state. At this time, one end of the rail 18 is pivotally connected to the shaft 15 by the pin 17, but the other end is in a state where it can move with respect to the shaft 20, so that the rail 18 can be smoothly inclined. Then, the fixing bolt 16, the fixing bolt 21, and the positioning bolt 22 are tightened and fixed at the desired inclined positions. FIG. 7 is a view showing a state where the rail 18 is inclined.

In this state, the same cutting operation as described above is performed. In this case, the circular saw blade 10 is held with the rail 18 inclined with respect to the plane of the table 1a and guided by the rail 18. Meanwhile, the cutting movement is performed, so that the cutting is inclined downward to the right in the drawing.

[0014]

According to the present invention, as described above, the push-off operation can be performed even in a stationary slide type cutting machine, and the size of the entire apparatus can be reduced. The movement of the circular saw blade is guided and regulated by the rail mechanism, so that the operator does not need a force against the urging force of the spring provided on the arm member,
Comfortable work can be performed. In addition, since the guide rail member has a structure that can be inclined with respect to the table, it is possible to easily perform operations such as inclined groove cutting.
