Protrusions 5e, 5e are formed on the right side of the bracket 5 in the figure, and a belt cover 53 is placed on the protrusions 5e, 5e and fixed by pins 54, 54. The belt cover 53 covers the back side (right side in FIG. 7) of the belt sander 38, and is configured to be easily attached to and detached from the bracket 5 by the pins 54, 54. Further, in the vicinity of the drive roller 27, a connecting pipe 55 connected to a dust collecting device (not shown) for collecting chips is arranged.

On the other hand, in FIG. 2, a guide plate fixing screw 56 is attached to the table 2, and the guide plate fixing screw 56 is provided with a guide plate 57 for guiding a material to be polished. The guide plate 57 is rotatable about the axis of the guide plate fixing screw 56, and the contact angle of the material to be polished with the belt sander 38 or the like can be adjusted. Further, the guide plate 57 is constructed so that its position can be adjusted in the left-right direction in FIG. On the other hand, in the center of the hollow member 13, a hollow member lifting / lowering regulation mechanism 58 is arranged.

The operation of the polishing board thus configured will be described in detail below. First, a case where the belt sander 38 is used in an upright state as shown in FIG. 8 will be described. In FIG. 2, the handle 11 is loosened, moved along the guide hole 1a, positioned at an appropriate position, and fastened, so that the holding plate is attached via the handle shaft 10 attached to the handle 11 in FIG. 4 also rotates about the rotation pin 3, and the bracket 5 also rotates. As a result, the drive roller 27 and the driven roller 50 (see FIG. 1) can be erected. Then, the surface plate 37 provided with the roller bracket 44 is fixed to the bracket 5. Then, as shown in FIG. 6, the belt sander 38 is provided between the driving roller 27 (see FIG. 1) and the driven roller 50 in a state where the side surface 46c of the lever 46 is in contact with the right side surface of the roller bracket 44 in the drawing. And rotate the lever 46 clockwise around the fulcrum portion 46b in FIG. Then, the lever 46 rotates while the tip 46a of the lever 46 slides on the right side surface of the roller bracket 44. Then, the holding body 45 moves leftward in the figure, and the driven roller 50 moves leftward in the figure, whereby the belt sander 38 is tensioned (FIG. 5). Further, after the belt sander 38 is stretched, the belt cover 53 is fixed to the bracket 5 by the pins 54, 54 in FIG. When systemizing a machine tool such as a table saw having the same height as the polishing machine with the polishing machine, a machine tool 92 having a table having the same height as the table 2 of the polishing machine 93 in FIG. 9 is used. It is placed beside the polishing board 93. Then, with the fixed handle 34 (see FIG. 3) loosened, the front and rear rails 36 are moved in the left-right direction in the drawing. The front and rear rails 36 are engaged with the engaging members 33 (FIG. 3) of the polishing board 93 and the engaging members (not shown) of the machine tool 92 with the groove portions 36a (FIG. 3) of the front and rear rails 36, so that the polishing board 93 By tightening the fixed handle 34 (FIG. 3) of FIG. 3 and the fixed handle (not shown) of the machine tool 92, the machine tool 92 and the polishing machine 93 are integrated. In this state, in FIG. 1, the motor 7 is driven to rotate the pulleys 8 and 9 via the motor shaft 7a. As the pulleys 8 and 9 rotate, the pulleys 19 and 24 rotate via the belts 20 and 25. As the pulley 19 rotates, the drive shaft 18 also rotates, and the drive roller 27 also rotates. The rotation of the driving roller 27 causes the belt sander 38 to move between the driven roller 50 and the driven roller 50. On the other hand, since the outer diameters of the pulley 19 and the pulley 24 are slightly different, the rotational speeds of the two pulleys 19 and 24 are different. Therefore, in FIG. 3, since the contact position between the contact portion 19a of the pulley 19 and the cam 24a of the pulley 24 changes, the pulley 19 moves up and down in FIG. Along with this, the drive roller 27 also moves up and down via the drive shaft 18. Therefore, one side of the belt sander 38 moves up and down, and the polishing efficiency can be improved. In this state, the material to be polished (not shown) is brought into contact with the belt sander 38 while being guided by the guide plate 57 (see FIG. 2), whereby the polishing work by the belt sander 38 can be performed. At this time, the machine tool 92 is placed beside the grinding machine 93 in FIG. 9 so as to be integrated, so that the table of the machine tool 92 can be used as an auxiliary table during the work of the grinding machine 93. Further, the material subjected to the cutting work or the like by the machine tool 92 can be polished by using the side polishing machine 93, and the work efficiency is good. Further, during the operation of the machine tool 92, the table of the polishing board 93 can act as an auxiliary table.

The hollow member 13 also moves up and down as the drive roller 27 moves up and down. Therefore, by controlling the vertical movement of the hollow member 13, the vertical movement of the drive roller 27 can also be regulated. That is, when the vertical movement of the drive roller 27 is not desired, the vertical movement of the hollow member 13 is regulated by operating the hollow member up-and-down regulating mechanism portion 58 (see FIG. 2), which in turn regulates the vertical movement of the drive roller 27. To do.

Further, by operating the handle 11 in FIG. 2 and appropriately inclining the bracket 5 (see FIG. 1), the working surface of the belt sander 38 is parallel to the surface of the table 2 as shown in FIG. Can be In this case, it is particularly effective for polishing a flat surface.

Further, when polishing is performed using a spindle sander 91 as shown in FIG. 11, the belt cover 53 (see FIG. 6), the belt sander 38 (see FIG. 6), the surface plate 37 (see FIG. 6) described above are used. (Ref.) Are removed in the reverse order. Further, in FIG. 3, the nut 28 is removed and the drive roller 27 is removed from the drive shaft 18. Then, the spindle sander 91 is inserted into the drive shaft 18, and the nut 28 is tightened and fixed (FIG. 12). In this state, the motor 7 (see FIG. 1) is operated to rotate and vertically move the spindle sander 91 in the same mechanism as the belt sander 38 described above. When the vertical movement of the spindle sander 91 is not desired, the vertical movement of the hollow member 13 is regulated by the above-mentioned hollow member raising / lowering regulating mechanism 58 (FIG. 2), and thus the vertical movement of the spindle sander 91 is prevented. Can be regulated. Even when this spindle sander is used, as shown in FIG. 9, by integrating the grinding machine 93 and the machine tool 92, as in the case of using the belt sander described above, the respective tables serve as auxiliary tables, The table area can be increased, and the polishing work can be performed immediately after the cutting work and the like, which improves work efficiency.

It should be noted that, in the above-described embodiment, the one in which both the belt sander 38 and the spindle sander 91 can be used as the polishing machine has been described, but the polishing machine that can selectively use both sanders is described. It may not be a disc, and may be, for example, a polishing disc dedicated to a belt sander or a polishing disc dedicated to a spindle sander.
