Abstract:
1. A jig device for fixing a casting block so as to cut it based on a base surface thereof, comprising: a main frame that forms a mounting portion and a front surface portion respectively corresponding to a lower part and a rear part of the casting block; a center guider that is formed in the center of the mounting portion to support the center of the lower part of the casting block; a base surface plate unit that is configured on the upper and lower center of the front surface portion to support the upper side and the lower side of the rear surface as a base surface through a cylinder, wherein the base surface plate includes a base surface plate cylinder, one or more upper and lower back/forth plates and a plurality of shaft-shape base surface dogs; a side surface pad unit that is configured on one side of the main frame to support one side surface of the casting block through a cylinder, wherein the side surface pad unit includes a side pad cylinder and a side pad; a lower lifting pad unit that is configured on the mounting portion respectively corresponding to both sides of the rear and front of the center guider to lower and raise the casting block through a cylinder; an upper clamping unit including an upper clamping cylinder, a both side clamping shaft and a both side upper clamper disposed respectively on both sides of the upper center of the front surface portion to fix both sides of the upper portion of the casting block through a cylinder and a hinge structure and wherein the both side clamper is configured to move forwards once the casting block is loaded from above therein; a lower clamping unit that is configured on the mounting portion corresponding to both sides of the center guider to fix both sides of the lower portion of the casting block through a cylinder; a sub clamping unit that is configured respectively at both sides of the front of the mounting portion to fix both sides of the front upper surface of the casting block through a cylinder, wherein the sub clamping unit includes a sub clamping cylinder and sub clamper; and a base surface pad unit that is configured at one side of the front surface portion to determine the contacting condition with the casting block according to the variation of air pressure.
