Description

Double travel universal vice

The utility model two-pass universal vice relates to field of mechanical technique, is applicable to that machine-building processing, repairing trades are as clamping tool.

In the clamping device of machine-building and repairing, " vice " had the history of centuries so far, but with regard to its structure, never done great improvement from bringing into use in 18th century at present.This vice is mainly by base, fixed caliper, and moving caliper and lining thereof, leading screw and nut thereof, jaw and screw nut are formed, and its weak point is: 1, it is not attractive in appearance to exist profile, and volume is big and heavy; 2, because have only a caliper motion, then exist the slow-footed problem of one-stroke; 3, jaw can not be used more, particularly circular work package is existed the holding workpiece instability, to the direct situation of clamping of the conical surface, inclined-plane workpiece.

The purpose of this utility model provides a kind of two-pass universal vice, and the jaw of this vice has two-pass and opening degree big (increasing nearly one times), can the stable holding circle, the purpose of workpiece such as square, taper, inclined-plane.

The design (Fig. 1) of the utility model two-pass universal vice is by worm screw (4), worm gear (5), outer moving caliper (6), leading screw (8), main body (18), interchangeable pincers seats (14), special screw (15), voussoir (16), jaw (17), key (13,23), interior moving caliper (19) and cylindrical shell (2), base (1) is formed, and it is that key (13) is used M that its assembling connects ₆Screw is fixedly connected on the worm gear (5), and then worm gear is placed in the groove of main body (18).Key (23) is put into outer moving caliper (6), again outer moving caliper is pushed in worm gear and the main body along key (13), interior moving caliper (19) is outside key (23) pushes in the moving caliper (6), leading screw (8) is installed in outer moving caliper (6) and goes up And by in the moving caliper (19) in the screw-in that is threaded, moving caliper (6) is gone up thrust ring (10) is installed outside then; And is with on the fixedly connected moving caliper outside of screw (9) of M6 * 24mm, handle (7) is arranged on one end of leading screw (8), retaining lid (20) is arranged on the other end, be fixedly connected on the leading screw (8) with the screw (21) of M6 * 15mm.Worm screw (4) is screwed in the worm gear (5), be screwed and be connected on the main body (18).Then cylindrical shell (2) is placed on the base (1), main body (18) is placed on the cylindrical shell, compresses with housing screw (24) to be connected on the base.

The interchangeable caliper seat (14) of two symmetries is fixedly connected on the inside and outside moving caliper (6,19) with soket head cap screw (11), voussoir (16) jaw (17) is fixedly connected on the interchangeable pincers seats (14) of two symmetries by special screw (15), then dust cap (22) is screwed and is connected on the interior moving caliper, even if constitute the two-pass universal vice, its course of action is:

1, unclamps locking device on the outer moving caliper (6), during rotational lead screw (8) (left-handed), outer moving caliper moves right at the thrust lower edge of leading screw key (13), interior adjustable clamp along key (23) to left movement (realize jaw open), otherwise then close up (holding workpiece).

2, when outer moving caliper is in locking state, rotational lead screw (8), interior moving caliper (19) can move to the left or to the right.

3, when workpiece in clamping, can do following two motions if unclamp the locking device of outer moving caliper at jaw (17): (1) can push away outer moving caliper and move to the left or to the right along key (13).(2), rotary worm (4), because of worm gear (5) drives key (13), key (13) drives the inner and outer movable caliper again and does the interior any rotation of 180 degree.

When 4, unclamping housing screw (24), main body (18) drives the inner and outer movable caliper and goes up any rotation of making 360 degree at base (1).

The effect of the utility model two-pass universal vice is compared with prior art: 1, the contact-making surface of jaw can be changed to square, circular, taper and ramp structure, has the characteristics of the various difform workpiece of stable holding; 2, because caliper can be made advance and retreat and rotatablely move under the state of holding workpiece, work has finishes the arbitrary orientation processing request in (multiplex's step) in a clamping (operation), as the milling inclined-plane, and skewed slot or reach the advantages such as hole of turning multicenter distance on lathe in boring on the inclined-plane; 2, when turning handle, be that leading screw (8) also rotates, can make inside and outside moving caliper do relative motion, be two-pass motion, relatively move, so just increased nearly one times opening degree thereby drive jaw, thereby accelerated the process of clamping workpiece, help car, mill, the work of work post such as plane, brill, boring, pincers, have that volume is little, in light weight, the effect of good looking appearance.

Fig. 1 is the structure chart of the utility model two-pass universal vice.
