However, if the clamping does not require such a large force Then, there is no need to provide holes lc and Id in the shaft 1. Instead, the step 2c on the right side of the annular piston 3a that releases air must be provided with a hole 8 that communicates with the outside of the hydraulic cylinder 2 in the same way as the step 2d. Example 1 'As shown in Fig. 5, the shaft 1 is arranged. Since the two rollers 9a can be strongly pressed down by the τ-shaped member 5 which is pressed down by two shafts 1, the one shaft is used instead. Since the T-shaped member 5 uses an L-shaped member (not shown), the roller 9a can be extended to the next structure. In Embodiment 1, the shaft 1 is turned to the right from the state of FIG. 2 to the state of FIG. When moving, if less force is needed, the shaft 1 can be moved to the right even without the ring piston 3a, so 'no The large inner diameter portion 2a on the left side of FIG. 1 is required, and the weight can be used to reduce the size of the device.

Therefore, if according to the second invention If the pressure fluid supply piping during the supply is damaged and the fluid pressure drops, the first trapezoidal block 30 can be stopped at the lowered position, so the workpiece 40 can be held in a held state. In particular, it is effective when the jig device 100 is installed on a vertical surface such as a column, and even if the fluid pressure is lowered, the workpiece 40 will not fall, and accidents can be prevented and safety can be maintained. If the clamp device 100 using the fluid pressure actuating rod of the second cylinder is used in a plurality of adjacent combinations, the space required for piping can be very simplified.

(Third invention) If the third invention is used, the force port JEL 59 shown in FIG. 6 can be simply and strongly held. (Fourth invention) As shown in FIGS. 4 and 5, if two shafts are used However, since the two rollers 9a arranged on both sides of the clamping bolt 31 are simultaneously pressed, the lowering operation of the clamping bolt 31 can be stabilized. When the fourth invention is used, the trapezoidal block buckle in Figure 丨 can be pressed down uniformly and reliably, so that the workpiece 40 can be surely clamped.

Patent application scope 1. 2. 4. A8 B8 C8 D8 A kind of hydraulic operating rod, which is characterized in that: a horizontally arranged hydraulic cylinder is inserted with a gap to slowly deepen the axis of the gap, the gap and the horizontal plane The angle between them is smaller than the friction angle. The hydraulic cylinder is provided with a through-hole penetrating upward. The through-hole is provided with a pressure-applying index by means of pressure, and a horizontal direction is provided below the rod. For the extended pin, the pin is engaged with the gap # of the shaft, and the hydraulic cylinder acts on the hydraulic cylinder to move the shaft from the deeper part of the gap to the shallower part and press the pin. According to item 丨 of the patent application scope, a hydraulic actuating lever is used, in which the second piece is arranged on the inclined surface of the first piece having a slope that swells laterally from the side to the upper end to make surface contact, and the second piece The upper and lower through-holes are provided, and the insertion from the upper side of the through-hole to the upper side has a larger protrusion than the through-hole A <the lever. When the pin is depressed, the first block piece is pushed out horizontally on the sloped side and descends. According to item 1 of the patent application scope, the cylinder center of the collet clamp is fixed on the upper part of the hydraulic actuator. Dry, according to the first, second, and third items of the patent application scope-as a rod 'wherein, the rod is placed on the two hydraulic cylinders and is pressed and simultaneously fitted into the hydraulic cylinder The axis of each is printed by the above-mentioned sales and consumption cooperative of the Central Standards Bureau of the Ministry of Economy.
