Claims

[Scope of Claim for Utility Model Registration] ■ The required number of barrens are placed on or embedded in the pallet P, and are connected to the hydraulic flow channels arranged in various ways in the barrel P, and are connected to each other through the hydraulic flow channels. In a hydraulic clamp cylinder for a jig that is operated by supplying and discharging high-pressure oil at the same time, a check valve 7 or a normally closed check valve 20 is provided in the flow path 5 communicating from the hydraulic flow path to the hydraulic clamp cylinder Hc, and the check valve 7 or the normally closed check valve 20, and the external opening/closing mechanisms 8 and 9 or 19 and 21, which can automatically return, are opened, and the high pressure oil supplied from the hydraulic flow path is individually introduced into the hydraulic clamp cylinder Hc. Features: Hydraulic clamp cylinder for jigs. ■ When installing the normally closed check valve 20 in the flow path 5, the flow path 5
is branched into supply channels 17■ and ■ and return channels 17■ and
The hydraulic clamp cylinder according to item 0, wherein a check valve 7 having no external opening/closing mechanism is attached to the return passages 17 (1) and 17 (2).
