    • 专利摘要:
    A boring tool comprising a tool head provided with a slot extending transverse to the axis of the tool head in which a pair of opposite cutting knives are guided movable in longitudinal direction of the slot. A spacer is guided in the tool head movable between a first and a second position. In the first position the spacer is located between inner ends of the cutting knives which are spring biased to engage the spacer to be movable with the latter in the longitudinal direction of the slot while holding the cutting knives in a cutting position. In the second position the spacer frees the cutting knives to move under the influence of the biasing springs toward each other to an inactive position.

    (54) BORSHTANGA
    one
    This invention relates to metal working, namely, to finishing of holes.
    Known boring bar with a device for removal of the cutter by means of a movable 5 in the axial direction of the remote element.
    The disadvantage of boring bars are limited technical capabilities.
    The purpose of the invention is the expansion of technical capabilities.
    The goal is achieved by the fact that the remote element is stepped and is installed with the possibility of radial movement., J
    FIG. 1 shows the proposed boring bar; in fig. 2 - section AA on 4ig. one.
    In the housing 1 of the boring bar, an axially movable axially mounted spring-loaded distance element 3 under the influence of the hydraulic cylinder 2 is used to retract the incisors 4 and 5, the incisors 4 and 5 are installed in diametrically located openings of the housing.
    Section 6 of the remote element 3 in contact with the cutters, consists of two stages 7 and 8, of larger diametral size and smaller, respectively.
    The remote element is mounted with the possibility of radial movement due to the fact that the stepped section 6 is made on the sleeve 9, which has an oval opening 10 through which the cylindrical spacer passes.
    Borshtanga works as follows.

    [1]
    At the beginning of the cutting process, the spacer is actuated by the hydraulic cylinder to the left to contact the incisors with a larger step of the stepped part of the remote element, and to remove the incisors from the surface to be processed, the stationary element is fed to the right to contact the incisors with a smaller step. Such constructive implementation of boring bar provides expansion of its technical capabilities. Claims of the invention Borstanga with a device for retracting a Reetz by means of a remote element moving in an axial direction 97300 44, characterized in that, with an extension of technical capabilities, the remote element is made stepwise and is installed with the possibility of radial movement.
