Abstract

(57) [Abstract] [Purpose] To eliminate the change in groove depth in slide cutting and perform groove cutting work with a uniform depth in a slide cutting machine that performs groove cutting work on a processed material. [Structure] Shaft holder 13 held by circular saw section 7
The shaft 14 is vertically slidably fitted to the upper surface of the base 1, the plate 15 is fixed to the lower portion of the shaft 14, and the sliding of the shaft 14 is fixed at an arbitrary position by the knob bolt 16. When the circular saw part 7 is pushed down, the processed material 1
If the lower surface of the plate 15 contacts the upper surface of the plate 2 and slide cutting is performed in this state, the deflection with the slide bar 4 and the like is eliminated, and the amount of cutting into the processed material 12 is constant, so that accurate groove cutting work can be performed. It can be carried out.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutting depth regulating device when grooving a slide cutting machine.

[0002]

[Prior Art]

 The conventional technique will be described with reference to FIG. FIG. 2 is a side view of a conventional slide type cutting machine. The circular saw part 7 holds a lower limit stopper 10 for setting the swing lower limit position of the circular saw part 7, and when performing a grooving operation on the work material 12, the cutting depth is set to an arbitrary depth. After adjusting the lower limit position of the circular saw part 7 up and down by the lower limit stopper 10, hold the circular saw part 7 at the upper limit position, hold the handle 11, and slide the circular saw part 7 toward you. Next, when the handle 11 is pushed down, the lower end of the lower limit stopper 10 contacts the upper surface of the protruding portion of the hinge 5 at the set lower limit position, and the circular saw part 7 is slid to the fence 2 side in the lower limit position for cutting. It was

[Problems to be solved by the device]

 Conventionally, when the handle 11 is pushed down and slid to perform cutting, the depth of cut is restricted by the lower limit stopper 10. However, the pressing force of the handle 11 causes the base 1, the slide bar 4, and the like to bend, and the depth of the groove changes between the front side and the fence 2 side. An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a slide-type cutting machine capable of grooving work with a uniform depth.

[0004]

[Means for Solving the Problems]

 According to the present invention, the shaft holder is arranged in the circular saw portion, the shaft is fitted into the shaft holder so that the shaft can be slid up and down, and the plate is fixed to the lower part of the shaft to slide the shaft. Freely fix at any position with a knob bolt so that the upper surface of the processed material and the lower surface of the plate abut.

[0005]

[Action]

 In the present invention, the lower surface of the plate, which is fixed at a predetermined position depending on the height of the processed material, contacts the upper surface of the processed material during grooving work, so the cutting depth of the cutting tool is kept constant with reference to the upper surface of the processed material. Can be kept at

【Example】

 An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a side view of the slide cutting machine of the present invention. In the figure, a fence 2 supporting a processed material 12 is fixed on the upper surface of a base 1, and a holder 3 is held behind the base 1. A slide holding member (not shown) is provided above the holder 3, and a hinge 5 is connected to the slide holding member via a slide bar 4 in parallel with the upper surface of the base 1 so as to be slidable back and forth. A circular saw portion 7 which is swingable up and down with respect to the base 1 is pivotally supported about a base point 6. A cutting tool 9 which is rotated by a motor 8 is held on the circular saw portion 7, and a lower limit stopper 10 for restricting the swinging lower limit position of the circular saw portion 7 is further provided. Reference numeral 11 is a notch handle. A shaft 14 is fitted in a shaft holder 13 held by the circular saw portion 7 so as to be vertically slidable toward an upper surface of the base 1, and a plate 15 is fixed to a lower portion of the shaft 14. The sliding of the shaft 14 is fixed by a knob bolt 16. In the above configuration, when performing a grooving operation on the processed material 12, the lower limit stopper 10 is moved up and down to adjust the cutting depth to an arbitrary depth, and the upper surface of the processed material 12 and the lower surface of the plate 15 are aligned. Slide the shaft 14 to the desired position and fix it with the knob bolt 16. Next, hold the handle 11 and slide the circular saw portion 7 toward you while keeping the upper limit position. Further, when the handle 11 is pushed down, the lower end of the lower limit stopper 10 contacts the upper surface of the protruding portion of the hinge 5 at the set lower limit position. When cutting is performed on the workpiece 12 while the circular saw portion 7 has reached the lower limit position, the lower surface of the plate 15 contacts the upper surface of the workpiece 12. In this state, by sliding the circular saw portion 7 toward the fence 2, it is possible to eliminate the bending of the sliding bar 4 and the like and perform a grooving operation with a uniform depth.

[0007]

[Effect of the device]

 According to the present invention, by providing the plate that regulates the groove depth with respect to the upper surface of the processed material, it is possible to eliminate the deflection of the slide bar and the like during the slide cutting and perform the groove cutting work with a uniform depth. The cutting accuracy can be improved.
