Zusammenfassung: | PURPOSE:To smoothly perform the buffer and housing operatons of a work head by connecting the work head with a supporter through a four-knotted parallel link with a buffer arm and an oil-pressure cylinder and a buffer mechanism. CONSTITUTION:A work head 2 is provided to a supporter 1 through a four- knotted parallel link A, a buffer arm 5 is attached in a rocking manner to the shaft of the supporting point of an upside arm 3 of the four-knotted parallel link A, and betwen the end of the buffer arm 5 and the shaft of the work head 2 for the upside arm 3 is connected with an oil-pressure cylinder 6. Then, the connected part between the buffer arm 5 and the oil-pressure cylinder 6 is connected to the supporter 1 through the buffer mechanism B. Thus, overloading to the work head 2 is offset of the buffer mechanism B and in housing the work head 2, the oil-pressure cylinder 6 is extended and lifted up by the four-knotted parallel link A. |
