Abstract
The invention discloses a bench screw. The bench screw comprises a base, a fixed jaw and a movable jaw, wherein the fixed jaw is fixedly arranged on the base; the movable jaw is fixedly connected with a screw rod; the screw rod is matched with a screw rod nut; the screw rod nut is fixedly arranged on the base; the base comprises a base body; the center of the base body is provided with a screw rod nut mounting hole; and a nut seat provided with the screw rod nut is disposed in the screw rod nut mounting hole and is welded with the base body. The bench screw is reasonable in structure, convenient to manufacture and use and excellent in working effect. Because the nut seat of the screw rod nut is arranged in the screw rod nut mounting hole and is welded with the base body, the bench screw is more convenient to manufacture, accurate in location and excellent in working effect; and the screw rod nut is very convenient to repair and exchange.
Description
Technical field
The present invention relates to a kind of instrument, is a kind of machining bench vice.
Background technology
Existing bench vice, the form that its feed screw nut slings for both sides, fragile, processing effect is undesirable.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, manufacture, easy to use, the bench vice of good working effect.
Technical solution of the present invention is:
A kind of bench vice, comprise base, regular jaw, moving jaw, it is characterized in that: regular jaw is installed on base, and moving jaw is fixedly connected with screw mandrel, and screw mandrel coordinates with feed screw nut, feed screw nut is installed on base; Described base comprises base body, and the central authorities of base body are provided with feed screw nut's installing hole, and the nut seat being provided with feed screw nut is loaded in feed screw nut's installing hole, and welds with base body.
Described feed screw nut has two sections, the front and back be parallel to each other; Internal thread in rear sector hole coordinates with the external screw thread of inner sleeve, and the inner surface of inner sleeve is the thread segment form alternate with smooth section on the circumferential surface, and shiny surface is concave form; The inner surface of front sector hole is the thread segment form alternate with smooth section on the circumferential surface, and shiny surface is concave form; The surface of screw mandrel is the thread segment form alternate with smooth section on the circumferential surface, and thread segment is in the convex form coordinated with the smooth section of inner sleeve and feed screw nut; Be provided with screw mandrel rotational positioning at inner surface of inner race to dash forward; Screw mandrel in inner sleeve can tandem motion and rotate form.
The present invention is rational in infrastructure, manufacture, easy to use, good working effect.Adopt " nut seat of feed screw nut is loaded in feed screw nut's installing hole, and welds with base body ", manufacture more convenient, registration, good working effect, and the maintenance of feed screw nut, change very convenient.Adopt feed screw nut to have two sections, the front and back form be parallel to each other, screw mandrel first by the closed jaw of tandem motion, then, is worked jaw jam-packed convenient, fast by slightly rotary screw.
