Description
Technical field
The utility model relates to a kind of lathe with the outer chuck of processing cylinder sleeve and pipe fitting special use.
Background technology
The outer chuck of traditional lathe, the mode that when the card workpiece, adopts two ends to hold out against mostly, this mode the inclined to one side phenomenon of feed occurs at the workpiece end face not at ordinary times easily, and this is the shortcoming of prior art.
Summary of the invention
The purpose of this utility model provides a kind of outer chuck of easy to use, accurate positioning, can effectively overcome the shortcoming of prior art.
The purpose of this utility model realizes according to following technical scheme, it comprises chuck seat, it is characterized in that: chuck seat is provided with a boss ring, the outside of this boss ring is by the gland that is threaded, in the boss ring, be provided with base, be fixedly connected with spring tension pawl on base, be provided with a pull bar at the inner chamber of spring tension pawl, an end of this pull bar passes the deck dish.Its end that is positioned at spring tension pawl inner chamber of described pull bar is taper, and the tapering of its tapering and spring tension pawl inner chamber matches.Its end that is positioned at spring tension pawl inner chamber of described pull bar is for spherical.
The utility model is owing to adopt technique scheme, and when pull bar inwardly moved, the stressed rising of spring tension pawl of jig can rise by workpiece, thus it have easy to use, the characteristics of accurate positioning.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 removes side view behind gland and the pull bar for the utility model.
In the accompanying drawing, 1-chuck seat, 2-gland, 3-spring tension pawl, 4-base, 5-pull bar, 6-boss ring, 7-hole.
