  The projecting member 510 is disposed on the front side (arrow F direction side) of the third frame 410 in the front-rear direction (arrow FB direction).

  Next, the connector 500 will be described with reference to FIG. Fig.8 (a) is a side view of the connection body 500, FIG.8 (b) is sectional drawing of the connection body 500 in the VIIIb-VIIIb line | wire of FIG. 8 (a).

  As shown in FIG. 8, the projecting member 510 of the connector 500 has a spherical ball 511 made of metal, and a male screw projected from the ball 511 upward (in the direction of the arrow U) and engraved on the outer periphery And a bolt portion 512 fastened to the third frame 410 of the grinder side frame 400.

  The support member 520 of the connector 500 includes a metal main body 521 formed in a cylindrical shape, and a magnetic part 522 disposed on the upper surface of the main body 521. At least a part of the magnetic portion 522 is a magnet, has an inner diameter substantially the same as the outer diameter of the sphere 511, and forms a spherical surface convex downward (in the direction of the arrow D). Therefore, the spherical body 511 is displaceably supported by sliding on the upper surface of the magnetic portion 522. In addition, the attraction force by the magnetic portion 522 can maintain the grinder side frame 400 in a predetermined posture with respect to the base side frame 300. On the other hand, when a force exceeding the adsorptive power of the magnetic portion 522 is applied (for example, when an excessive displacement occurs in the grinder G), the spherical portion 511 (projecting member 510) is moved from the magnetic portion 522 (support member 520). It can be separated.

While being able to maintain a predetermined posture, it is possible to allow free movement of the grinder G (the grinder side frame 400) relative to the base member 100 (the base side frame 300). Thereby, the sensible person can experience the behavior in which the grinder G is displaced in multiple directions.

  Next, referring to FIG. 9, the regulating body 600 will be described. Fig.9 (a) is a front view of the control body 600, FIG.9 (b) is sectional drawing of the control body 600 in the IXb-IXb line | wire of Fig.9 (a).

  As shown in FIG. 9, in the restricting body 600, the opening of the main body 610 is formed in a circular shape in a front view, and the buffer rubber 620 is provided over the entire circumference of the inner peripheral surface of the opening. The buffer rubber 620 is formed in a U-shaped (groove) shape in cross section, and is engageable with the inner edge of the opening of the main body 610. The inner diameter of the opening of the main body 610 is smaller than the outline of the cover g2 of the grinder G, the clamping base 430 and the clamping cover 440 (see FIG. 1).

  The restricting body 600 is fixed to the base side frame 300 (second frame 320) by bolts (not shown) between the sandwiching base 430 and the sandwiching cover 440 and the cover g2 of the grinder G in the front and rear direction (arrow F-B direction). Fastened and fixed. Further, the grip portion g1 of the grinder G is inserted through the opening of the main body 610 (see FIGS. 1 and 2). Therefore, the displacement of the grinder G can be suppressed by the contact between the inner circumferential surface of the opening of the main body 610 and the grip portion g1 of the grinder G. At the time of contact, shock is buffered by the buffer rubber 620.

  The inner diameter of the opening of the main body 610 is smaller than the outer diameter of the cover g2 of the grinder G and the pinching base 430 and the pinching cover 440. Displacement of the grinder G in the forward direction (arrow F direction side) is suppressed by the abutment of the clamping base 430 and the clamping cover 440 with the restricting body 600. it can.

  Therefore, displacement of the grinder G can be regulated to a predetermined amount while permitting displacement of the grinder G in multiple directions. Thus, the grinder sensation apparatus 1001 can be miniaturized. In addition, the grinder G can abut on the case body 700, and the case body 700 can be prevented from being damaged. Therefore, it is possible to prevent the broken part of the case body 700 and the grinder G from coming into contact with the user, and to experience the behavior of the grinder G safely.

  Further, when the cover g2 of the grinder G abuts on the restricting body 600, the contact between the grinding stone g3 and the restricting body 600 can be suppressed, and damage to the restricting body 600 can be suppressed.

  Referring back to FIG. 1 to FIG. 3, the method of feeling by the grinder physical sensation apparatus 1001 will be described.

  The feeling by the grinder physical sensation device 1001 is operated with the grinder G held on the grinder side frame 400, the plug of the grinder G (not shown) connected to the outlet 830 of the operation panel 800 and the power switch of the grinder G turned on. The switch 820 of the board 800 is pressed. As a result, the grinding stone g3 starts to rotate, and the reaction force associated with the rotation reaction force of the grinding stone g3 and the contact with the workpiece W makes it possible to experience a sudden displacement or runaway of the grinder G. That is, the plug can be inserted into the outlet 830 while the power switch is turned on to simulate an aspect in which the grinder G runs wild.

  In this case, since the grinder G and the work material W are disposed inside the arrangement space partitioned by the case body 700, the grinder G is protected from the exposed grinder G and chips generated thereby. Can safely experience the behavior of Further, since the case body 700 has light transparency, the behavior of the grinder G can be visually recognized by the experienced person from many directions.

  As described above, since the posture of the grinder G can be maintained at a predetermined position by the attraction of the spheres 511 by the magnetic portion 522 (see FIG. 8), the above operation (feeling) is performed using the grinding stone g3 of the grinder G as a work material W The state may be started from the state in which the grinding stone g3 of the grinder G is separated from the workpiece W. In the former case, it is possible to experience the behavior of the grinder G due to the influence of rotational inertia when the rotation of the grindstone g3 is started, and in the latter case, when a repulsive force is applied from the workpiece W to the grindstone g3. It is possible to experience the displacement behavior of the grinder G.

  Here, according to the grinder physical sensation device 1001, since the gripping member 450 is disposed (projected) outside the disposition space from the opening formed in the back plate 720 of the case body 700, By holding it, it is also possible to experience the behavior (a runaway) of the grinder G via the holding member 450.

  As a method of feeling the grinder G by holding the holding member 450, first, while holding the holding member 450, pressing the switch 820 keeps the power switch ON as described above. A method is illustrated in which a plug (not shown) is inserted into the outlet 830 to experience an aspect in which the grinder G suddenly goes wild. In particular, when the switch 820 is pressed in a state where the grindstone g3 is in contact with the work material W, the grindstone g3 in contact with the work material W starts to rotate, and the grinder G is moved by the reaction force. You can experience the behavior of being greatly plunged.

  Second, with the grindstone g3 rotated, the grinder G is displaced by the operation of the holding member 450, and the side surface (peripheral surface) of the grindstone g3 is brought into contact with the work material W, whereby the side surface of the grindstone g3 ( An example is given of a method in which the outer peripheral surface is carelessly applied to a wall or the like to experience a mode in which the grinder G is flipped. The grinder G can be displaced by the operation of the gripping member 450, and the bottom surface (axial end face) of the grinding stone g3 can be brought into contact with the work material W, so that the reaction force at the time of appropriate grinding can be felt.

  Third, when operating in a state where there is a defect in the grinding stone g3 (for example, a state in which the grinding stone g3 is attached at a position offset to the drive shaft or a state in which the grinding stone g3 partially missing is attached) The method of making the sensible person experience the behavior (vibration) of the grinder G is illustrated. That is, the behavior of the grinder G with a defect can be experienced by a person having a feeling.

  In this case, in the workpiece fixing member 200, a plurality of clamp levers 240 are disposed on the movement trajectory of the grindstone g3 when the grinder G is displaced with the connector 500 as a fulcrum. That is, the plurality of workpieces W can be fixed on the movement trajectory of the grindstone g3. Therefore, for example, the work material W fixed by the clamp lever 240 at the center (center in the arrow L-R direction) is higher than the work material W fixed by the clamp levers 240 on the both sides (arrow U-D direction) By making the size small (low), it is possible to change the portion (bottom and side) of the grinding stone g3 to be brought into contact with the material to be cut W without requiring replacement of the material to be cut W. Can be easily increased.

  In addition, the gripping member 450 is disposed at the rear end (end on the arrow B side) of the third frame 410, and the projecting member 510 is disposed on the front side (arrow F direction side) of the third frame 410 . That is, the distance from the protruding member 510 (connection body 500) to the gripping member 450 can be made larger than the distance from the grindstone g3 to the protruding member 510 (connection body 500). Therefore, even when the repulsive force acting on the grindstone g3 is small and the displacement of the grinder G is small, the displacement of the gripping member 450 can be increased, and the repulsive force acting on the gripping member 450 can be increased accordingly, and the behavior of the grinder G Can be fully experienced.

  When a force exceeding the attraction of the magnetic portion 522 is applied to the grinder G, the sphere 511 (projecting member 510) can be separated from the magnetic portion 522 (support member 520) (see FIG. 8), for example When the grindstone g3 tries to get over the corner or protrusion of the work material W when the side surface (peripheral surface) of the grindstone g3 is made to abut on the work material W, the grinder G is separated by the above-described separation. Can experience the behavior of large displacement.

  On the other hand, when the force acting on the grinder G is equal to or less than the adsorption force of the magnetic portion 522, the behavior of the grinder G in a state where the grinder G is held by the base side frame 300 (base member 100) via the connector 500. Can be experienced.

And (iv).

  The base member 2100 includes a metal plate portion 2110 formed in a plate shape having a substantially rectangular shape in top view, and conductive rubber rubber feet 120 disposed by fastening at four corner portions on the lower surface of the plate portion 2110. Equipped with

  Openings 2111 and 2112 are formed in the plate portion 2110. The opening 2111 is a hole having a substantially rectangular shape in top view in the central portion of the plate portion 2110, and the opening 2112 is formed on both sides of a stand 2310 described later as a circular hole in top view. The cord g4 of the grinder G is inserted into the opening 2112 and wired to an external outlet using a space formed by raising the rubber foot 120.

  In the present embodiment, the work material W is directly fixed to the plate portion 2110 by fastening with a bolt (not shown).

And a connecting body 2500 to be connected.

  The base side frame 2300 includes a stand 2310 disposed on the upper surface of the plate portion 2110 of the base member 2100, a first metal frame 2320 formed in a plate shape bent in a side view shape, and the first frame 2320 The second frame 2330 is disposed on the first frame 2320 so as to project to the front, and a bearing unit 2340 is connected to the stand 2310 so that the first frame 2320 can be displaced (rotated).

  The stand 2310 includes a base 2311 fastened and fixed to the plate portion 2110, and a metal shaft 2312 which is erected from the base 2311 in the vertical direction (arrow U-D direction) and formed in a cylindrical shape. The bearing unit 2340 includes a bearing 2341 in which the shaft 2312 of the stand 2310 is fitted in the inner ring, and a holder 2342 holding the outer ring of the bearing 2341 and fastened and fixed to the first frame 2320. Thus, the first frame 2320 is rotatable with respect to the base member 2100 (plate portion 2110) with the shaft 2312 of the stand 2310 as a rotation center.

  The grinder side frame 2400 is disposed on the third frame 2410 via a metal third frame 2410 formed in a plate shape, a support 2420 erected from the upper surface of the third frame 2410, and the support 2420. And a resinous sandwiching cover 2430.

  The support 2420 is formed so that its entire length can be adjusted (stretched), and by adjusting the entire length of the support 2420, the grip portion g1 of the grinder G can be held between the third frame 2410 and the holding cover 2430.

  The connector 2500 has a shaft holder 2510 that protrudes downward (in the direction of arrow D) from the lower surface of the third frame 2410 of the grinder side frame 2400, and a horizontal posture (that is orthogonal to the shaft 2312 of the stand 2310). And a metal shaft 2520 fixed as an axis, and a bearing unit 2530 rotatably holding the shaft 2520.

  Since the shaft 2520 and the shaft 2312 of the stand 2310 are disposed in a posture orthogonal to each other, the grinder G (the grinder side frame 2400) can be displaced in multiple directions.

  The bearing unit 2530 includes a bearing 2531 in which the shaft 2520 is fitted to the inner ring, and a holder 2532 that holds the outer ring of the bearing 2531 and is fastened and fixed to the first frame 2320. As a result, the grinder side frame 2400 (third frame 2410) is rotatable relative to the base side frame 2300 (first frame 2320) with the shaft 2520 as the rotation center (see FIG. 15).

  In addition, the grinder side frame 2400 includes a distance adjustment mechanism 2540 and a coil spring 2550.

  One end of the coil spring 2550 is engaged with the post 2331 formed on the lower surface of the second frame 2330, and the other end is engaged with the post 2411 formed on the upper surface of the third frame 2410. Arranged in a state. The grindstone g3 of the grinder G can be pressed against the work material W with a predetermined force by utilizing the elastic recovery force of the coil spring 2550.

  Therefore, regardless of the size and shape of the grinder G, the work material W or the grindstone g3, and even when the grindstone g3 is worn, the grindstone g3 can be brought into contact with the work material W. That is, the behavior of the grinder G in a state in which the grindstone g3 and the work material W abut against each other is reliably performed without performing complicated operations such as adjustment of the attachment position of the grinder G and adjustment of the inclination angle of the grinder side frame 2400. I can feel it.

  The behavior of the grinder G can be adjusted by changing the magnitude of the pressing force by changing the magnitude of the pressing force of the grinder g3 of the grinder G against the work material W by changing the coil spring 2550. .

  The restriction body 2600 includes a metal main body 2610 fastened and fixed to the plate portion 2110 of the base member 2100 with a bolt, and a rubber shock absorbing rubber 2620 fastened and fixed to the main body 2610 with a bolt. A pair is arranged in a posture toward the grinder G.
