摘要： A clamp device (1) capable of easily and securely fixing an object to be clamped to a base part, allowing the reduction of production cost by its simplified structure, and capable of fixing the object to be clamped to the base part by its engagement with the inner peripheral wall part or side wall part of the hole part of the object to be clamped, comprising a rod support part (5) rotatably supporting a clamp rod (3) on a clamp body (2) so as to be selectively switched between a clamp position and a clamp release position by moving the engagement part (25) of the clamp rod (3) in a direction generally orthogonal to the longitudinal direction of the clamp rod (3), a piston drive mechanism (6) drivingly moving a piston member (4) between a clamp operation position and a clamp operation release position, and a cam mechanism (7) driving the engagement part (25) of the clamp rod (3) in a clamp direction (generally rightward) by the drive force of the piston drive mechanism (6) driving the piston member (4) in the clamp operation position.

摘要： A positioning and fixing device capable of increasing positioning accuracy for positioning a fixed object relative to a base body, allowing a reduction in manufacturing cost by reducing the number of parts, and capable of maintaining high positioning accuracy and stable clamped state even when the device is repeatedly used for a long period. The positioning and fixing device (3) comprises a positioning mechanism (13) having an annular tapered surface (40) formed on the outer peripheral part of a cylindrical shaft part (10b) for horizontally positioning a work pallet (1) and reduced in diameter toward the axial tip side of the cylindrical shaft part (10b) and an annular engagement part (41) formed on the inner peripheral part of an annular engagement member (11) engageably with the annular tapered surface (40) and elastically deformable in the radial direction by the engagement thereof with the annular tapered surface (40). The engagement part (41) further comprises a tapered ring part (50) allowed to come into surface contact with the annular tapered surface (40) and a plurality of ribs (51) arranged continuously with each other from the tapered ring part (50) to the radial outer side.

摘要： A work pallet positioning and fixing device that is capable of positioning in two directions, horizontal and vertical, through elastic deformation of an annular engaging portion, of reliably elastically deforming also in a peripheral local area with the engaging portion reliably elastically deforming throughout the periphery, and so on. In positioning a work pallet (1) on a base body (2) by a positioning and fixing device (3), an annular relief groove (68) allows an engaging portion (66) integrally formed on a bush (60) to elastically deform in the diameter increasing direction, and since the engaging portion is formed with a plurality of slits (70), the engaging portion (66) easily elastically deforms in the diameter increasing direction to maintain the annular taper surface (67) of the engaging portion (66) in close contact engagement relation to the annular taper surface (23) of a cylindrical shaft (10b); therefore, the work pallet (1) can be accurately positioned horizontally and vertically on the base body (2), without the danger of the positioning accuracy being lowered by cutting chips or the like.
