- the resiliently urged presser 9 a engaging portion 1 1 2) of the rotating body 6 is engaged with the engagement recess 1 1 1 of the pressing body 5 so that the pressing body 5 and the rotating body 6 The pressing body 5 is prevented from rotating relative to the first rotation position and the second rotation position between the first rotation position and the second rotation position. Rotate.
- the presser 9 a is engaged with the engagement recess 11 1, and the pivoting body 6 and the pressing body 5 are engaged. Turns together. Then, by pivoting the pivoting body 6 from the intermediate pivoting position toward the other pivoting position, the first sliding surface 5 b and the second sliding surface 6 c are slipped, and the engagement recess 1 is formed. The engagement between 11 and the presser 9 a is released. On the other hand, when the pivoting body 6 is pivoted from the other pivoting position toward the other pivoting position, the presser 9 a engages with the engagement recess 11 1 in the middle thereof .
- the pressing release position of the pressing body 5 has a width, that is, a height.
- the pressing body 5 moves from the side away from the pressing position to the side closer to the pressing position. It has become to move. Therefore, the pressing body 5 can be rotated at the position away from the work 2 in the same direction as the axial center 7, ie, in the vertical direction, and the pressing body 5 is rotated in the first direction. Even when there is an obstacle on the way from the position to the second rotation position, the pressing body 5 can get over the obstacle.
- the pressing body 5 since the pressing body 5 approaches the pressing position while rotating from the first pivoting position to the second pivoting position, the pressing body 5 moves between the pressing release position and the pressing position at the second pivoting position. It is possible to reduce the stroke between them. Therefore, the pressing force for pressing the work 2 by the pressing body 5 can be increased.
- the first guiding surface 15 2 (first elongated hole 4 g) is the second guiding surface 1 7 1 (second elongated hole 4). Compared to h), the inclination is gentler, and the pressing force for pressing the work 2 can be further increased.
- the present invention is not limited to the above-described embodiment, and various other modifications are possible.
- the fixing portion 1 may be an MC pallet, a machine table, or any other table.
- the fixed object is not the work 2 but may be, for example, a jig, a fixture or a mold.
- the contact means 1 10 in the clamp device 3 is composed of a coil spring 8 as an elastic member, and a plunger 9 as an engagement recess 11 1 and an engagement member 1 13. Recess 11 1 and plunger 9 may be omitted.
- the main body 4 is provided with a plate-like base portion 4b for mounting and fixing to the fixing portion 1, but instead, as shown in FIG. 12, the main body 4 has a tool such as a spanner or the like.
- the tool hooking portion 1 8 1 to be hooked, 1st external thread portion 1 8 3 screwed with the nut 1 8 2 and 2nd external thread portion 1 8 4 to be screwed into the fixing portion 1 May be
- the rotary body 6 is not provided with the operating handle 6 g for rotating operation, but as shown in FIG. 13, a tool hooking portion 1 91 is provided to which a tool 190 such as a spanner etc. is hooked. It may be done.
- the rotation range limiting means 130 is not limited to the convex portion 1 31 provided on the main body 4 and the concave portion 1 3 2 provided on the pressing body 5 as shown in FIGS. As shown in 5, a recess 1 32 formed by a notch in the tip of the outer cylinder 201 fixedly attached to the main body 4 and a protrusion of the pressing body 5 extending laterally from the through hole 5a side. It may consist of part 1 3 1. That is, the rotation range limiting means 130 may be composed of a concave portion 132 on the side of the main body 4 and a convex portion 131 on the side of the pressing body 5.
- the clamp device 3 is provided with a coil spring 8 biased between the main body 4 and the pressing body 5, instead of the coil spring 8, as shown in FIG. It may be provided with an elastic piece 301 as an elastic member constituting at least the contact means 110 such as a flat panel or a spring washer which is biased between the pressing body 5 and the like.
- the elastic piece 301 is also an elastic body as an element constituting the holding means 120 and an elastic material as an element constituting the supporting means 160.
- the guided protrusion 1 51 is provided on the rotating body 6, and the guiding surfaces 1 52 and 1 7 1 are provided on the main body 4.
- the protrusions 1 51 may be provided on the main body 4 and the guide surfaces 1 52 and 1 7 1 may be provided on the rotating body 6.
- the engagement recess 1 1 1 is provided on the pressing body 5 and the plunger 9 as the engagement member 1 1 3 is provided on the turning body 6, but on the contrary
- the engagement recess 1 1 1 is provided on the rotating body 6, and the plunger 9 is provided on the pressing body 5.
- the clamp device according to the present invention is used to fix a work, a jig, a fixture, or a mold to a fixture base, an MC pallet, a machine table or the like.
