In addition, as shown in FIG. 5, the width | variety of the division | segmentation groove | channel 53 is made larger than the base diameter of the press member 40 so that the base 40a of the press member 40 can enter.

  Then, with the cam surface 54 applied to the flat washer 43, the flange 38 of the pressing member 40 is pressed through the flat washer 43 and the disc spring 42, and the pressing member 40 is pressed against the elasticity of the coil spring 41, and the lever The fixed shaft 57 is press-fitted into the fixed shaft holding hole 15 through the shaft hole 55 of the member 50. Further, the handle 52 of the lever member 50 protrudes from the holder main body 12, that is, at the reference position of the lever member 50, as shown by the solid line in FIG. Extend to stick out.

  In this state, the pressing member 40 is urged by the urging force of the coil spring 41 and pressed against the cam surface 54 via the flat washer 43 and the disc spring 42, and the tip surface 36 of the pressing member 40 is a straight line of the support member 24. It is separated from the inclined bottom surface 31 of the groove and faces the inclined bottom surface 31. The lever member 50 is held by the holder body 12 so as to be rotatable in the horizontal direction from the back side to the front side of the holder body 12 as indicated by a two-dot chain line in FIG. .

  As described above, the holder 10 having the support member 24, the pressing member 40, the lever member 50, and the like attached to the holder body 12 is fixed to a fixture base, an MC pallet, a machine table, or the like as shown in FIG. Placed on the base 60 (in the illustrated embodiment, placed on the fixture base).

  Then, the two stepped screw insertion holes 19 of the holder main body 12 are aligned with the screw holes 61 formed in the fixing base 60, and the fixing bolts 62 each having, for example, a hexagonal hole are inserted into the stepped screw insertion holes 19 respectively. The tip of the fixing bolt 62 is screwed into the screw hole 61 and tightened until the head 63 of the fixing bolt 62 abuts against the stepped portion of the stepped screw insertion hole 19, and the holder main body 12 is fixedly mounted on the mounting surface 64 of the fixing base 60. To do.

  In this way, the holder 10 is mounted on the mounting surface 64 of the fixed base 60 to hold the object to be fixed such as a workpiece together with other holders of the same type or other types, fasteners or positioning tools. Fix it.

  At a position where the holder 10 is attached, the workpiece 66 as a fixed object is supported by being placed on the shaft member 28 of the support member 24. Alternatively, the shaft member 28 and the nut member 29 may be eliminated, and the support member 24 may be made of only the main body member 27 and placed on the main body member 27 so that the workpiece 66 is directly supported by the main body member 27.

  Now, when holding the workpiece 66 using the holder 10, the workpiece 66 is placed on the shaft member 27 of the support member 24. Then, the support member 24 enters the support member insertion hole 13 of the holder body 12 against the elasticity of the coil spring 23. At this time, the air in the support member insertion hole 13 escapes to the outside through the vent hole 21, and the support member 24 moves smoothly.

By pressing the pressing member 40 against the support member 24, the movement of the support member 24 is fixed by frictional resistance due to surface contact.

  At this time, when the workpiece 66 is heavy, as shown in FIG. 8, the support member 24 penetrates deeply into the support member insertion hole 13, and the inclined bottom surface 31 of the linear groove facing the tip surface 36 of the pressing member 40 becomes shallow. If the lever member 50 is rotated to a small extent, the distal end surface 36 comes into contact with the inclined bottom surface 31. On the other hand, when the workpiece 66 is light, the support member 24 enters the support member insertion hole 13 shallowly as shown in FIG. 9, and the inclined bottom surface 31 of the linear groove facing the tip surface 36 of the pressing member 40 is deepened. The lever member 50 is largely rotated until the front end surface 36 contacts the inclined bottom surface 31. In FIG. 2, H is the minimum rotation position, K is the maximum rotation position, and the lever member 50 fixes the movement of the support member 24 within the rotation range of the minimum rotation position H and the maximum rotation position K. .

  By the way, in embodiment mentioned above, the holder main body 12 was made into one rectangular parallelepiped block shape. However, as shown in FIGS. 10 and 11, for example, the holder main body 12 is held by the first main body portion 12A that holds the support member 24, the second main body portion 12B that holds the lever member 50, and the pressing member 40. The third main body portion 12C may be divided and configured. Here, the third main body portion 12C may not be provided, and a plurality of third body portions 12C may be provided instead of one.

  In this way, the lever member 50 is moved away from the end portion of the workpiece, such as the central portion of the workpiece, such as in the center, where the operator's hand cannot be inserted. By rotating, the movement of the support member 24 can be easily fixed by remote control. When one or more, that is, one or a plurality of third main body portions 12C are provided, the long pressing member 40 can be held by the third main body portions 12C, and remote operation with a longer distance can be handled. .

  In the embodiment shown in FIGS. 10 and 11, each of the first main body portion 12A, the second main body portion 12B, and the third main body portion 12C constituting the holder main body 12 is passed through a stepped screw insertion hole 68. Fix to a fixing base (not shown) with fixing bolts (not shown) with hexagonal holes. Then, one pressing member 40 is held by these three portions 12A, 12B, and 12C, and the lever member 50 is rotated to move the pressing member 40 against the support member 24 to support the workpiece 66. The movement of the support member 24 is fixed.

  The object to be fixed held by the holder 12 is not limited to a workpiece (work). For example, a workpiece (workpiece) such as a jig or a fixture base such as a jig plate to which the jig is attached is mounted. ) Other than that.
