Description

  The present invention relates to a rail adapter that is detachably attached to a base of a cutting tool, a cutting tool with a rail adapter including the rail adapter, and a cutting tool with a guide device.

  A portable cutting machine (portable circular saw) generally has a structure in which a main body with a built-in motor is connected to an upper portion of a base, and a circular saw blade (blade) driven to rotate by the electric motor has a predetermined amount of base. A workpiece (work material) that protrudes from the bottom surface and is set on the bottom surface side of the base is processed with the circular saw blade (Patent Document 1 below).

  A long guide member (ruler plate) is used when a workpiece is cut straightly over a long distance by a portable cutting machine. A rail portion (guide protrusion) extending in the longitudinal direction is provided on the upper surface of the guide member. The interconnection between the portable cutting machine and the guide member is performed by a rail adapter. The rail adapter is provided with an engaging portion (a guide recess extending in the cutting progress direction) that engages with the rail portion of the guide member. By fixing the rail adapter to the base of the portable cutting machine and engaging the rail adapter engaging part with the rattle of the guide member without rattling (slidably fitted), the portable cutting machine is long. It is possible to accurately move linearly over a distance, and it is possible to easily perform an accurate cutting operation of a workpiece.

JP 2012-213829 A

  The rail adapter is provided with two guide bars extending vertically in the same direction before and after the cutting progress direction. By fixing these two guide bars to the base of the portable cutting machine from the side, the rail adapter is provided. Is attached to a portable cutting machine. For this reason, when attaching the two guide bars to the base of the portable cutting machine, the circular saw blade is positioned (contacted) on the end surface of the guide member serving as the cutting line, and the side surface of the circular saw blade is The fixing bolt had to be tightened while adjusting the insertion depth of the two guide bars with respect to the base of the portable cutting machine so as to be parallel to the rail portion of the guide member. Here, the guide bar is displaced during tightening of the fixing bolt, and the guide bar is often fixed to the base in the displaced state. As described above, the work of fixing the guide bar to the base of the portable cutting machine is a very troublesome work.

  In addition, when the workpiece is inclined and cut, if the position of the inclined fulcrum of the circular saw blade does not coincide with the bottom of the base, the cutting line will be closer to the rail adapter side compared to the case of right-angle cutting if no adjustment is made. (It will not coincide with the end face of the guide member). Therefore, even when the rail adapter is attached to the base of the portable cutting machine with great effort to cut the workpiece at right angles, the circular saw blade is again positioned on the end face of the guide member when performing inclined cutting. However, it was necessary to retighten the fixing bolt while making a troublesome adjustment that the side surface of the circular saw blade is parallel to the rail portion of the guide member. The above problems are common to other cutting tools such as jigsaws.

Embodiment 1
A first embodiment of the present invention will be described with reference to FIGS. The front-rear direction is defined by FIG. The rail adapter 10 of this Embodiment is detachably attached to the tool base 2 of the portable cutting machine (portable circular saw) 1 as a cutting tool as shown in FIGS. The portable cutting machine 1 to which the rail adapter 10 is attached is an example of a cutting tool with a rail adapter. Moreover, what attached the rail adapter 10 to the portable cutting machine 1, and also engaged the rail adapter 10 with the guide member 20 is an illustration of the cutting tool with a guide apparatus.

  The rail adapter 10 is made of metal such as stainless steel, and is used to connect the portable cutting machine 1 and the guide member 20 to each other when the workpiece 30 is cut straight at a long distance by the portable cutting machine 1. It is done. As shown in FIG. 1, the rail adapter 10 includes an adapter base 15, an eccentric dial 17 as a restricting member, and a guide bar 18. The adapter base 15 has a guide recess 16 as an engaging portion that engages with a rail portion 22 of a guide member 20 described later. The guide recess 16 extends parallel to a cutting line by the portable cutting machine 1 to which the rail adapter 10 is attached. The eccentric dial 17 is supported by the adapter base 15 so as to be rotatable about a rotation shaft 17b (screw), and regulates a distance between the adapter base 15 and a tool base 2 described later. The guide bar 18 is fixed to the front end portion and the rear end portion of the adapter base 15 by screws or the like, and extends to the tool base 2 side.

  The eccentric dial 17 is made of resin, and in the state shown in FIG. 1 (corresponding to right-angle cutting), it does not protrude from the end surface 15a (end surface on the tool base 2 side) of the adapter base 15 to the tool base 2 side, and is in the state shown in FIG. In the case of 45 ° inclined cutting), the adapter base 15 protrudes from the end surface 15a of the adapter base 15 to the tool base 2 side by a predetermined amount X. Although not shown, the eccentric dial 17 protrudes from the end face 15a of the adapter base 15 toward the tool base 2 even in a state rotated 90 ° from the state shown in FIG. 1 (corresponding to 30 ° inclined cutting) ( The amount of protrusion is smaller than X). That is, the eccentric dial 17 can change the protrusion amount from the end surface 15a of the adapter base 15 to the tool base 2 side according to its rotational position. The eccentric dial 17 is provided on the adapter base 15 by a rotating shaft 17b that is a screw so that the eccentric dial 17 can be rotated by applying a certain force or more in the rotational direction. When the eccentric dial 17 projects from the end surface 15a of the adapter base 15 to the tool base 2 side, the outer peripheral surface of the eccentric dial 17 comes into contact with the end surface 2a of the tool base 2 so that the tool base 2 moves relative to the adapter base 15 side. Thus, the distance between the adapter base 15 and the tool base 2 is restricted. The eccentric dial 17 does not restrict the relative movement of the tool base 2 toward the non-adapter base 15 side. On the upper surface of the eccentric dial 17, 0, 30, 45 and numerals are displayed. Each number corresponds to the inclination angle of the circular saw blade 4 of the portable cutting machine 1. The operator can select the protruding amount of the eccentric dial 17 corresponding to each inclination angle by matching each number with an arrow or the like shown on a part of the adapter base 15. The outer peripheral surface of the eccentric dial 17 has a flat surface portion 17 a at a position corresponding to an inclination angle of 45 ° of the circular saw blade 4. When the flat surface portion 17a contacts the tool base 2, the direction connecting the contact portion and the rotating shaft 17b is the same as the insertion direction of the rail adapter 10 with respect to the tool base 2.

  Since the portable cutting machine 1 to which the rail adapter 10 is attached has the same configuration as that conventionally used, only a brief description will be given below. As shown in FIGS. 3 to 6, the portable cutting machine 1 includes a tool base 2, a tool body 3, and a circular saw blade (blade) 4. The tool base 2 is a substantially rectangular plate made of metal such as aluminum. The tool base 2 is a base to which the rail adapter 10 is attached. The longitudinal direction of the tool base 2 coincides with the cutting direction. The bottom surface of the tool base 2 is a sliding surface with the guide base 21 of the guide member 20. When the cutting operation is performed without using the guide member 20, the bottom surface of the tool base 2 is a sliding surface with a processing material (work material) 30 such as wood. The tool body 3 can be tilted around the tilting fulcrum A as shown in FIG. 6 with respect to the tool base 2 by a known tilt position adjusting mechanism (not shown), and by a known cutting depth adjusting mechanism (not shown). The tool base 2 is supported so as to be rotatable up and down. The circular saw blade 4 is supported by the tool body 3 so as to protrude downward from the tool base 2. The rotation of a motor (not shown) built in the tool body 3 is transmitted to the circular saw blade 4 via a reduction mechanism (not shown), and the circular saw blade 4 is rotationally driven. The fixing bolt 7 is provided in the tool body 3 in order to fasten and fix the guide bar 18 of the rail adapter 10 from above.

  The guide member 20 is a long ruler plate, and is used when the work material 30 is straightly cut at a long distance by the portable cutting machine 1. The guide member 20 is fixed to the workpiece 30 by a clamp or the like (not shown). The guide member 20 includes a guide base 21 and a rail portion (guide convex portion) 22. An end surface 21 a of the guide base 21 is parallel to the rail portion 22 and serves as a cutting line by the portable cutting machine 1. Although not shown in the drawing, a rubber fluff prevention plate is attached to the end surface 21a of the guide base 21 along the traveling direction of the portable cutting machine 1, and this fluff is prevented during cutting operation. It is necessary to fix the guide bar 18 by setting the position of the circular saw blade 4 so as to contact the working plate.

  The preparation procedure for the right-angle cutting is, for example, as follows. The tilt position of the tool body 3 with respect to the tool base 2 is set so that the circular saw blade 4 is perpendicular to the bottom surface of the tool base 2. Further, the eccentric dial 17 of the rail adapter 10 is set in the state shown in FIGS. Then, the guide bar 18 of the rail adapter 10 is inserted (inserted) into a through hole (not shown) of the tool base 2. The insertion depth is set until the end surface 15a on the tool base 2 side of the rail adapter 10 contacts the end surface 2a on the adapter base 15 side of the tool base 2 (FIGS. 3 and 5). That is, it is assumed that a part of the rail adapter 10 and a part of the tool base 2 come into contact with each other in the insertion direction. Then, the guide bar 18 is fastened and fixed by the fixing bolt 7 of the tool body 3 in a state where the end surface 15 a of the rail adapter 10 and the end surface 2 a of the tool base 2 are abutted with each other. Thereafter, the guide concave portion 16 of the rail adapter 10 is engaged with the rail portion 22 of the guide member 20 (fitted without backlash). Then, the circular saw blade 4 is positioned on (contacts with) the end surface 21 a of the guide base 21, and the side surface of the circular saw blade 4 is parallel to the rail portion 22 of the guide member 20. That is, in the present embodiment, the end surface 15a of the rail adapter 10 and the end surface 2a of the tool base 2 are abutted with each other so that the circular saw blade 4 is positioned on the end surface 21a of the guide base 21, and the circular saw blade The four side surfaces are dimensionally parallel to the rail portion 22 of the guide member 20.

  The preparation procedure for inclined cutting is, for example, as follows. The tilt position of the tool body 3 with respect to the tool base 2 is set so that the circular saw blade 4 is inclined at a desired angle with respect to the bottom surface of the tool base 2. Here, as shown in FIG. 6, since the tilting fulcrum A is above the bottom surface of the tool base 2 and closer to the rail adapter 10 than the circular saw blade 4, for example, in the case of 45 ° inclined cutting, right-angle cutting and In comparison, the cutting line (circular saw blade 4) approaches the rail adapter side by a distance X. For this reason, the tool base 2 needs to be separated from the adapter base 15 by a distance X as compared with the case of right-angle cutting. Therefore, the eccentric dial 17 of the rail adapter 10 is set in a state shown in FIGS. 2 and 4 (a state in which a predetermined amount X protrudes from the end surface 15a of the adapter base 15 to the tool base 2 side). Then, the guide bar 18 of the rail adapter 10 is inserted into a through hole (not shown) of the tool base 2, and the outer peripheral surface of the eccentric dial 17 (the flat portion 17 a in the case of 45 ° inclination) abuts (contacts) the end surface 2 a of the tool base 2. When the guide bar 18 is tightened with the fixing bolt 7, the tool base 2 is fixed in a state of being separated from the adapter base 15 by the distance X. Thereafter, the guide recess 16 of the rail adapter 10 is engaged (fitted) with the rail portion 22 of the guide member 20. Then, the circular saw blade 4 is positioned on (contacts with) the end surface 21 a of the guide base 21, and the side surface of the circular saw blade 4 is parallel to the rail portion 22 of the guide member 20. In the case of 30 ° inclined cutting, the rotational position of the eccentric dial 17 may be rotated by 90 ° from the state shown in FIGS.

  According to the present embodiment, the following effects can be achieved.

(1) The rail adapter 10 has its end face 15a and the end face 2a of the tool base 2 abutted to each other so that the circular saw blade 4 in a state of being cut at right angles is positioned on the end face 21a of the guide base 21, and Since the side surface of the blade 4 is dimensioned to be parallel to the rail portion 22 of the guide member 20, the fixing bolt 7 is tightened while finely adjusting the insertion depth of the guide bar 18 with respect to the tool base 2. The rail adapter 10 can be easily attached and fixed to the tool base 2 without a troublesome work, and the usability can be greatly improved.

(2) The rail adapter 10 can change the amount of protrusion of the eccentric dial 17 from the end surface 15a of the adapter base 15 to the tool base 2 side by changing the rotational position of the eccentric dial 17, and the protrusion of the eccentric dial 17 can be changed. Since the distance between the adapter base 15 and the tool base 2 is regulated according to the amount, setting the rotational position of the eccentric dial 17 according to the angle of inclined cutting makes it easy as in the case of right-angle cutting. In addition, the rail adapter 10 can be attached and fixed to the tool base 2 and the usability can be greatly improved.

(3) Since the eccentric dials 17 are provided in total, one each before and after the cutting progress direction, the side surface of the circular saw blade 4 and the guide recess 16 of the rail adapter 10 should be parallel to each other with high accuracy. Can do.

(4) Since the configuration that regulates the distance between the rail adapter 10 and the tool base 2 is completed on the rail adapter 10 side, no configuration change is required for the portable cutting machine 1 to which the rail adapter 10 is attached. It is preferable because the introduction cost is low.

(5) When the flat surface portion 17a comes into contact with the tool base 2, the direction connecting the contact portion and the rotating shaft 17b is the same as the insertion direction of the rail adapter 10 with respect to the tool base 2. 2 is less likely to turn the eccentric dial 17. For this reason, it is easy to adjust the force during adjustment, and it is easy to use.

Embodiment 2
A second embodiment of the present invention will be described with reference to FIGS. 7 to 9, illustration of the guide member 20 and the tool body 3 shown in FIGS. 3 and 4 is omitted. In the first embodiment described above, the eccentric dial 17 as the restricting member is provided on the rail adapter 10, whereas in the present embodiment, the eccentric dial 8 as the restricting member is provided on the tool base 2. The eccentric dial 8 has the same shape as the eccentric dial 17 shown in FIG. 1, is supported by the tool base 2 so as to be rotatable about the rotation shaft 8b, and rotates to project from the rotation shaft 8b to the rail adapter 10 ( The distance between the rail adapter 10 and the tool base 2 is regulated by changing the projection amount. Specifically, the eccentric dial 17 regulates the relative movement of the rail adapter 10 toward the tool base 2 by contacting the guide bar 18 of the rail adapter 10 with the outer peripheral surface of the eccentric dial 17. The distance between the base 2 is restricted. The eccentric dial 8 does not restrict the relative movement of the rail adapter 10 toward the counter tool base 2 side. In the present embodiment, the width adjusting bolts 19 are provided at the front end portion and the rear end portion of the rail adapter 10, respectively. When the width adjusting bolt 19 is loosened, the side wall 16a of the guide recess 16 can be moved in the width direction, and when the width adjusting bolt 19 is tightened, the side wall 16a can be fixed at an arbitrary position in the width direction. Accordingly, the rail adapter 10 can be used even if the width of the rail portion 22 of the guide member 20 shown in FIG. In the present embodiment, the guide recess 16 also functions as an adapter base that supports the guide bar 18.

  The preparation procedure for the right-angle cutting and the inclined cutting is, for example, as follows. The tilt position of the tool body 3 with respect to the tool base 2 is set so that the circular saw blade 4 has a desired angle with the bottom surface of the tool base 2. Further, the eccentric dial 8 is set at a rotational position in accordance with the inclination angle. Note that the example of FIG. 8 corresponds to 45 ° inclined cutting, and the example of FIG. 9 corresponds to right-angle cutting. Then, the guide bar 18 of the rail adapter 10 is inserted (inserted) into a through hole (not shown) of the tool base 2, the tip of the guide bar 18 is abutted against (contacted with) the outer peripheral surface of the eccentric dial 8, and the guide bar 18 is fixed. Tighten with bolts 7 and fix. Thereafter, as in the case of the first embodiment shown in FIGS. 3 to 6, the guide concave portion 16 of the rail adapter 10 is engaged (fitted) with the rail portion 22 of the guide member 20. Then, the circular saw blade 4 is positioned on (contacts with) the end surface 21 a of the guide base 21, and the side surface of the circular saw blade 4 is parallel to the rail portion 22 of the guide member 20. The distance between the tool base 2 and the rail adapter 10 in the right-angle cutting is an example of the first distance, and the same distance in the 45 ° inclined cutting is an example of the second distance. Other points of the present embodiment are the same as those of the first embodiment. According to the present embodiment, the same effects as those of the first embodiment can be obtained except that the configuration of the portable cutting machine 1 needs to be changed.

Embodiment 3
A third embodiment of the present invention will be described with reference to FIGS. While the eccentric dial 17 is used as the restricting member in the first embodiment, the plate 12 is used as the restricting member in the present embodiment. The knob 13 is an operation unit for the user to change the protruding amount of the plate 12 from the end face 15 a of the adapter base 15. FIG. 10 shows a state where the plate 12 does not protrude from the end face 15 a of the adapter base 15. FIG. 11 shows a state in which the knob 13 is slid and the plate 12 is projected from the end face 15 a of the adapter base 15 by a predetermined amount X. The knob 13 is provided with a metal leaf spring 14, and the leaf spring 14 is engaged with an engaged portion (not shown) provided on the inner surface of the adapter base 15 that accommodates the knob 13. A plurality of engaged portions are provided, and in this case, the inclined angles are provided at four locations corresponding to 0 degrees, 15 degrees, 30 degrees, and 45 degrees. When the leaf spring 14 is engaged with the engaged portion, the knob 13 is restricted from moving in the protruding direction, but when a force of a certain level or more is applied to the knob 13, the leaf spring 14 is deformed and engaged. Is released, and the knob 13 is allowed to move in the protruding direction. Although not shown, a scale indicating the corresponding inclination angle may be displayed on the side of the knob 13. The preparation procedure for the right-angle cutting and the inclined cutting may be performed in the same manner as in the first embodiment. Other points of the present embodiment are the same as those of the first embodiment. The present embodiment can achieve the same effects as those of the first embodiment.

  The present invention has been described above by taking the embodiment as an example. However, it is understood by those skilled in the art that various modifications can be made to each component and each processing process of the embodiment within the scope of the claims. By the way. Hereinafter, modifications will be described.

  The cutting tool to which the rail adapter 10 is attached is not limited to a portable cutting machine, and may be another type such as a jigsaw. In the first embodiment, the configuration in which the end surface 15a of the adapter base 15 is in contact with the end surface 2a of the tool base 2 during right-angle cutting is illustrated. However, the outer peripheral surface of the eccentric dial 17 is also connected to the end surface 2a of the tool base 2 even during right-angle cutting. It is good also as a structure which contacts. Similarly in the third embodiment, the plate 12 may be in contact with the end surface 2a of the tool base 2 even in the case of right-angle cutting. In the first embodiment, the flat portion of the outer peripheral surface of the eccentric dial 17 may be added corresponding to one or both of the inclination angles 0 ° and 30 °. The same applies to the eccentric dial 8 of the second embodiment. Further, although two eccentric dials 17 and two knobs 13 are provided, only one may be used.

  In the embodiment, for example, when the end surface 15a of the adapter base 15 and the end surface 2a of the tool base 2 are brought into contact with each other, the side surface of the circular saw blade 4 comes into contact with the end surface 21a of the guide base 21, Although the case where the dimensional relationship of the tool base 2 and the guide member 20 was adjusted mutually was demonstrated, the application range of this invention is not limited to such a case. By having a basic configuration in which the distance between the rail adapter and the tool base (attachment base) is variably regulated, the rail adapter can be easily attached to the tool base as compared with the conventional case.
