In some cases, the seal may be incomplete and pressure fluid may leak, making it impossible to supply sufficient power. If the pressing force of the press plate 4 is increased to eliminate this inconvenience, the pallet 3
comes off from the positioning pin 1, and as a result, the pressure contact plate 4
The supply port 6 in the pallet 3 and the inlet port 5 in the pallet 3
Of course, it will be impossible to connect to Palette 3.
A problem arises in which it becomes impossible to even position the object.

価になる問題があつた。 Furthermore, the apparatus shown in FIG. 6 has a structure in which the side edges of the pallet 3 are sandwiched between the pressure contact plate 14 and the receiving seat 15 in order to communicate the supply port 16 and the inflow port 17. Although there is no particular risk of such a problem occurring, since the pressure contact plate 14 is pressed against the pallet 3 from below, it is difficult to set the upper limit position of the pressure contact plate 14, and the entire device becomes complicated and expensive. It was hot. That is, in the apparatus shown in FIG. 6, it is common to first raise the press plate 14 and abut it against the pallet 3, and then lower the receiving seat 15 so that the pallet 3 is sandwiched between the two. Pressure contact plate 14
It is necessary to stop the pallet 3 at an appropriate position so that it does not push up the pallet 3. Conventionally, a stopper 21 is provided for this purpose, but the position of the bottom surface of the pallet 3 rarely matches the position determined in the design due to the accumulation of machining errors of each component. , the position of the stopper 21 must be determined by so-called on-site alignment, and in that case, the position of the pressure contact plate 1
The work was unavoidably troublesome, as it was necessary to take care not to impair the sealing performance due to the surface contact between pallet 4 and pallet 3. Also three cylinders 1
1, 12, and 20, the total number of valves increases by providing a valve for each,
As a result, the overall structure becomes complicated and expensive.

し正確に面接触する。Function In this device, when the direct-acting actuator is operated to move the pressure plate toward the receiving seat, the surface of the pressure plate that forms the supply port comes into surface contact with the target member to be supplied. . When the actuator is further operated in this state, since the floating body to which the actuator is attached is supported by the elastic body and is in a floating state, the floating body is moved by the reaction force caused by pressing the press plate against the supplied member. The actuator moved together with the actuator, and as a result, the receiving seat integrated with the floating body moved toward the pressure plate, and eventually the supplied material was partially sandwiched between the pressure contact plate and the receiving seat, ensuring sealing performance. In this state, the supply port and the inflow port communicate with each other. That is, both the pressure contact plate and the receiving seat move around the supplied member. In addition, in this invention, the floating body and the pressure plate are movably attached to the same guide shaft, the pressure plate is attached to a rod that is substantially integrated with the actuator attached to the floating body, and the rod is attached to the receiving seat. Since it is engaged with the machine frame so that it can move in the axial direction, it has high rigidity to support the pressure plate, and as a result, the pressure plate is prevented from bending, and the pressure plate can accurately face the supplied material. Contact.

れた効果を得ることができる。Effects of the Invention As is clear from the above explanation, according to the device of this invention, a direct-acting actuator for moving the pressure contact plate and a receiving seat for clamping the supplied member together with the pressure contact plate are integrally provided on the floating body. Moreover, since the floating body is supported by an elastic body and made movable, when the supplied member is clamped, the floating body moves due to the reaction force from the supplied member, and as a result, the receiving seat and Since the pressure contact plate moves around the supplied member, it is possible to eliminate inconveniences such as pushing and moving the positioned supplied member.
In addition, since the pressure contact plate was supported by two shaft-like members, the guide shaft and the rod parallel to the guide shaft,
The pressure contact plate has high rigidity against bending loads, and therefore accurately moves in parallel to come into surface contact with the supplied member, so that the supply port and the inflow port can be connected with good sealing performance. Furthermore, with this invention, all operations can be performed by a single direct-acting actuator, and there is no need for a stopper to accurately stop the pressure plate, making it a simple and inexpensive device. It is possible to obtain excellent practical effects such as the ability to
