Abstract

The utility model relates to a bench clamp and the jaws of the bench clamp, which is used for clamping the work piece in the machinery industry. The utility model is provided with a screw rod [3] which is rotated around the fixed nut, and the screw rod [3] drives the movable clamp body [1] to combine with the fixed clamp body [5]. The utility model is characterized in that the upper ends of the movable clamp body [1] and the fixed clamp body [5] are respectively provided with jaws filling slots [2] and [6]; a planar style jaw [9], a concave V-shaped jaw [10] and a convex V-shaped jaw [11] which can be unloaded and loaded quickly from the jaws filling slots [2] and [6] and exchanged to each other. The three jaws can form six compositions which can totally obtain the maximal clamping area and the optimal clamping force when clamping various shape work pieces. The utility model has the advantages of the quick replacement of the jaws, convenience of clamping work pieces, etc.

Description

But the bench vice of quick change jaw and jaw

Bench vice and jaw that a kind of machinery industry clamping workpiece is used.

The common table vice has a screw mandrel (3) around hold-down nut rotation, and screw mandrel (3) drives moving caliper (1) with fixed caliper (5) closing and clamping work pieces.A pair of jaw is a plane, is fastened on respectively on moving caliper (1) and the fixed caliper (5) with four screws.Its shortcoming is to make various difform workpiece all obtain maximum grip face and best chucking power.It is not only to non-planar clamping workpiece difficulty, and workpiece easily takes place to slide and the damage workpiece in process.If adopt the non-planar jaw to come clamping non-planar workpiece, change jaw at every turn and all will dismantle four screws and screw four screws, waste time and energy, very inconvenient.

The purpose of this utility model provides a kind of bench vice with jaw fitting recess and assembly cover jaw, accomplishes that jaw can change fast, and clamping different shape workpiece can both obtain maximum grip face and best chucking power.

Formation of the present utility model and embodiment are provided by accompanying drawing:

Fig. 1 is the bench vice structure chart with jaw fitting recess.

Fig. 2 is the sectional view and the constitutional diagram thereof of three kinds of supporting jaws.

Fig. 3 is pack into the schematic diagram of jaw fitting recess (2) of jaw (9).

As shown in Figure 1, the upper end of moving caliper (1) and fixed caliper (5) has jaw fitting recess (2) and (6) respectively.Its cell body is a rectangle, also can make single splitter type or two splitter type.Iron-stone accounts for four shaping holes being convenient to hammering processing usefulness on (7), its diameter is respectively 8 millimeters, 6 millimeters, 4 millimeters, 2 millimeters.

Supporting jaw has three kinds six, i.e. (9) two of plane jaws, (10) two of recessed V-type jaws, (11) two of protruding V-type jaws.Therefore shown in figure two, above-mentioned jaw can constitute A, B, C, D, six kinds of combinations of E, F, clamping different shape workpiece easily.Between the lower end of jaw (9), (10), (11) and the jaw fitting recess (2) (6) is movingly, so jaw (9), (10), (11) can draw off from jaw fitting recess (2), (6) apace and pack into, changes mutually.After hours, all jaw can be put into the tool box, and is both convenient, again safety.

Compare with common bench vice, the utlity model has quick replacing jaw, the characteristics such as clamping workpiece convenience.

Claims

1, bench vice and the jaw used of a kind of machinery industry clamping workpiece, it has a screw mandrel [3] around the hold-down nut rotation, screw mandrel [3] drives moving caliper [1] and fixed caliper [5] closing, feature of the present utility model is that the upper end of moving caliper [1] and fixed caliper [5] has jaw fitting recess [2] and [6] respectively, plane jaw [9], recessed V-type jaw [10], protruding V-type jaw [11] can draw off from jaw fitting recess [2], [6] apace and pack into, change mutually.

2, by described bench vice of claim 1 and jaw, it is characterized in that the jaw fitting recess (2) and the cell body of (6) they are rectangle, also can make single splitter type or two splitter type.

3,, it is characterized in that between the lower end of jaw (9), (10), (11) and jaw fitting recess (2), (6) for movingly by claim 1 or 2 described bench vice and jaws.
