Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of a slide maroon, which is an example of a slide type cutting machine, FIG. 2 is a side view, and the slide marnoco 1 is behind a base 2 on which a circular turntable 3 is mounted so as to be horizontally rotatable at a substantially center. (Left side of FIGS. 1 and 2), the arm 4 is connected, and two parallel slide bars 6 and 6 serving as slide bodies can be slid in the front-rear direction on the holding portion 5 provided at the upper end of the arm 4 It is held. Reference numeral 7 denotes a rear end portion that connects the rear ends of the slide bars 6, 6, and 8 denotes a front end portion that connects the front ends to each other. The slide bar 6 has a stroke in which the rear end portion 7 and the front end portion 8 abut against the holding portion 5. , 6 can slide back and forth.

  Also, as shown in FIG. 3, a pair of left and right brackets 9, 9 is formed at the front end portion 8, and the base end portion 11 of the main body 10 is vertically moved by the support shaft 12 between the brackets 9, 9. It is rotatably mounted on the shaft. The main body 10 is provided with a disk-like saw blade 14 as a rotary blade that is driven to rotate by a motor 13 in the front-rear direction, and is normally attached to the upper limit position by a torsion spring (not shown) provided at the base end portion 11. It is energized. Reference numeral 15 denotes a safety cover for the saw blade 14, and 16 denotes a handle. The arm 4 is connected to the turntable 3 so that it can tilt at any angle to one side.

  Further, on the left and right sides of the base 2, guide fences 17 are fixed by bolts 18, 18,... The guide fence 17 has a guide surface whose front surface is perpendicular to the upper surface of the turntable 3 and is used for positioning of the material to be cut. Since the mounting holes of the bolts 18 in the base 2 are round holes that are slightly larger than the diameter of the bolts 18, the fixing positions at both ends of the guide fence 17 can be slightly moved back and forth.

  Therefore, when the slide marnoco 1 is operated by turning on the switch 19 provided on the handle 16 to drive the motor 13 and the saw blade 14 is rotated, when the handle 16 is gripped and the main body 10 is lowered, The workpiece to be cut placed on the table 3 can be cut at right angles to the guide fence 17. Further, when the turntable 3 is rotated, the angle cutting in which the angle of the saw blade 14 is changed in the horizontal direction can be performed, and when the arm 4 is tilted, the inclined cutting in which the angle of the saw blade 14 is changed in the vertical direction can be performed. Furthermore, when the main body 10 cut into the material to be cut is operated to be pushed backward at the front position, the main body 10 moves backward together with the slide bars 6 and 6, so that the slide cutting is possible.

  The support shaft 12 is provided with an adjustment mechanism for adjusting the saw blade 14 in parallel with the sliding direction of the main body 10. As shown in FIG. 3, the adjusting mechanism includes first and second small-diameter portions 20 and 20 that are coaxially provided at both ends of the support shaft 12 and are rotatably fitted to the left and right brackets 9 and 9, respectively. 2 is inserted into a connecting hole 22 of a sleeve 21 as an operation member (holding body). The connecting hole 22 is formed at a position eccentric from the axis of the sleeve 21 as shown in FIG. Further, a hexagonal head 24 similar to a bolt is connected to the outer surface side of each sleeve 21 coaxially with the sleeve 21 via a flange 23. At the periphery of the flange 23, a notch 25 is provided as a mark at the position in FIG. 3 where the connecting hole 22 is on the upper side, and the outer surface of the bracket 9 along the flange 23 rotates on the flange 23. A scale 26 is provided as an indication of the amount of movement of the notch 25 accompanying the above. Further, a screw hole 28 is formed above the bracket 9, a set screw 29 is screwed into the screw hole 28, and the sleeve 21 can be fixed at an arbitrary rotational position by screwing the set screw 29.

  When assembling the slide maroon 1 configured as described above, after setting the turntable 3 on the base 2 and temporarily fixing the guide fence 17 with the bolts 18, the arm 4 and the slide bars 6 and 6 are assembled to the turntable 3. The base end portion 11 of the main body 10 is positioned between the brackets 9 and 9 of the front end portion 8 of the slide bars 6 and 6 and is pivotally supported by the support shafts 12, and the sleeves 21 are assembled to the brackets 9 to the connection holes 22. The small-diameter portions 20 of the support shaft 12 are inserted, and the sleeves 21 and 21 are set at a rotational position where the connecting hole 22 is on the upper side. Then, the support shaft 12 is horizontally held between the brackets 9 and 9 via the sleeves 21 and 21.

  Here, as shown in FIG. 6A, when the guide fence 17 and the saw blade 14 are both inclined with respect to the sliding direction S of the main body 10, the sleeve 21 is interposed via the hexagonal head 24 with a wrench or the like. , 21 are synchronized and rotated point-symmetrically (for example, the right side is rotated forward by 5 degrees and the left side is rotated backward by 5 degrees). Then, as shown in FIGS. 5A and 5B, the support shaft 12 is twisted while maintaining a horizontal posture, and the left and right end portions are tilted in opposite directions. Since the angle of the main body 10 is also changed according to the tilt of the support shaft 12, the direction of the saw blade 14 can be adjusted to the sliding direction S as shown in FIG. The parallelism of the saw blade 14 is confirmed as follows, for example.

  The main body 10 is moved to the frontmost slide position, and a rectangular parallelepiped backing plate manufactured with high dimensional accuracy is placed on the turntable 3 in contact with the left side surface of the saw blade 14. 10 is gradually slid backward. If the saw blade 14 is tilted counterclockwise when viewed from above (the state shown in FIG. 7), a gap is gradually formed between the contact plate and the saw blade 14, and conversely tilted clockwise. If there is, the contact plate is pushed by the saw blade 14 and moves to the left on the turntable 3. The operator determines the inclination direction of the saw blade 14 depending on whether the gap is opened or the contact plate moves, and adjusts the angle of the saw blade 14 as appropriate. Of course, the contact position of the abutting plate may be the right side surface of the saw blade 14, and the tilt direction can be determined in the same manner even when the main body 10 is slid from the rear to the front.

  After confirming the parallelism of the saw blade 14 in this way, the bolt 18 of the guide fence 17 is loosened to make a fine movement state, and after aligning the guide fence 17 at a right angle with respect to the saw blade 14 as shown in FIG. This is fixed with bolts 18. The right angle with the saw blade 14 may be confirmed using a curved scale or the like applied to the saw blade 14 and the guide fence 17. Therefore, the parallelism of the saw blade 14 with respect to the sliding direction of the main body 10 and the right angle of the guide fence 17 can be adjusted. Note that a dial gauge may be used instead of a backing plate or a curved scale, and the adjustment work may be performed while viewing the measured value.

As described above, according to the slide maroon 1 and the assembling method thereof, the slide bar 6 and the main body 10 are connected between the pair of brackets 9, 9 provided on the left and right sides of the front end portion 8. Assuming that the end portion 11 is positioned and the brackets 9 and 9 and the base end portion 11 are pivotally attached to the support shaft 12, a sleeve 21 capable of tilting one end of the support shaft 12 in the front-rear direction to one bracket 9. The other bracket 9 is provided with a sleeve 21 capable of tilting the other end of the support shaft 12 in the front-rear direction opposite to the tilt side of one end, so that the slide direction of the main body 10 and the saw blade 14 are parallel to each other. Adjustment can be made quickly and accurately. In particular, since the support shaft 12 can be directly tilted using the left and right sleeves 21, the adjustment procedure is simple and does not take time and effort. Therefore, adjustment work can be easily performed including the initial setting in the assembly process.
Further, since the sleeve 21 (holding body) is employed as the first and second operation members, the operation members can be easily formed.
On the other hand, according to the assembly method including adjustment of the guide fence 17, the guide fence 17 can be accurately assembled on the basis of the sliding direction of the main body 10, which leads to improvement of cutting accuracy and reduction of cutting resistance.

In the above embodiment, the rotation position of the sleeve with the connection hole on the upper side is set as an initial setting, but the rotation position with the connection hole on the lower side may be set as an initial setting. Moreover, although the small diameter part was provided in the edge part of the spindle, and it connected with the sleeve, you may connect the edge part of the spindle which is not made into a small diameter part with holding bodies, such as a sleeve.
Further, in the above embodiment, a connecting hole is provided in the sleeve serving as the holding body, and the two are connected by inserting the small diameter portion of the support shaft. Conversely, the inner side of the holding body without the connecting hole is provided. It is also possible to connect the two by projecting a pin at an eccentric position on the end face and inserting the pin into a connecting hole provided on the end face axis of the support shaft. In this case as well, the support shaft is tilted by the rotating operation of the holding body. In addition, in addition to the bolt head shape as described above, a knob screw, a lever, or the like may be provided on the holding body so as to be rotatable.
In addition, in the above embodiment, the left and right brackets are each provided with a sleeve as a holding body, but the holding body is provided only on one of the brackets, and the sliding direction of the main body can be adjusted only by tilting one end of the support shaft. It is also possible to adjust the parallelism with the saw blade.

On the other hand, in addition to the screw hole 28 and the set screw 29, for example, in the case of the above-described form, the holding body locking mechanism is hinged with a regulating member that fits the hexagonal head and stops the rotation. Or a structure in which a pin is inserted into and removed from a recess or a through hole provided on the side surface of the sleeve.
In addition, the present invention can also be applied to a slide mark saw and a cutting machine other than the above-described forms such as a slide body having a single slide bar, a turntable not provided, and a type in which an arm does not tilt.
