Abstract
The utility model provides a modified bench vice, its characterized in that's drive disk assembly comprises spline screw rod and nut, little helical pitch screw rod and nut, locating piece and reset spring or comprises big helical pitch screw rod and nut, little helical pitch screw rod and nut and gearshift. When the clamp body is unloaded, the movable clamp body can move quickly by mainly driving the spline screw rod and the nut or by the large-lead screw rod and the nut; when the workpiece is clamped, the small lead screw and the nut are used for transmission, so that labor is saved or pressing force can be increased. The bench vice has the advantages of improving the labor efficiency and lightening the labor intensity.
Description
The utility model relates to a kind of improved bench vice, particularly a kind of energy fast advance and retreat and labour-saving bench vice.
Though existing bench vice model kind is more, its drive disk assembly is a screw rod and its nut that matches is formed, and caliper is unloaded and finish by the rotation of this screw rod when compressing object.Example: its drive disk assembly of bench vice of the 150mm type that sell in existing market is exactly to be made up of steel screw rod and the cast iron nut of T26 * 5 or T24 * 5(GB784-65).The bench vice of this drive disk assembly of being made up of single screw rod and nut, in use have following deficiency: one, bench vice is when zero load, and moving caliper can not be advanced and retreat rapidly, needs turning handle continually, wastes time and energy.Two, during clamping article,, need bigger hand-power because of the screw rod helical pitch is bigger.
But the purpose of this utility model provides a kind of fast advance and retreat and labour-saving bench vice.
The purpose of this utility model realizes by following design and scheme.
Its design is to change drive disk assembly into two parts to form, and a part can be carried out caliper fast when zero load, and another part makes can be laborsaving when compressing object, and its design can realize by following two schemes.One, by spline screw rod and nut (promptly milling several axial notches) on the surface of common screw and the inner surface of nut, (its helical pitch than the little 01-06 of helical pitch that will improve the bench vice drive screw doubly for one location and a resetting means and little helical pitch screw rod, the middle little 01-04 in footpath is doubly, and is as follows) and nut composition drive disk assembly.Spline screw rod and nut are the parts that caliper can be advanced when zero load fast, and this is because the jog of spline screw rod and nut has the state of two relative positions, the one, and the attitude that matches, at this moment the spline screw rod can slide in splined nut; The 2nd, misfit attitude, the spline screw rod then can not slide by axis.When clipping to object, spline screw rod and nut are in misfit attitude and make spline screw rod location with positioner, at this moment change again by little helical pitch screw drive, advance moving caliper to compress object, because the helical pitch of little helical pitch screw rod, in the footpath little, can reduce hand-power or increase thrust so compare with the improved bench vice of want.Two, drive disk assembly is by big helical pitch screw rod (its helical pitch compares and the big 1-7 of the drive screw that will improve bench vice times, and is as follows) and nut, and little helical pitch screw rod and nut and gearshift are formed.Caliper by big helical pitch screw drive, promotes moving caliper fast and advances when zero load, clip to object after, then change the transmission of little helical pitch nut into by gearshift.Gearshift is made up of butterfly spring, circumference pin, flat spring, overcoat.
The utlity model has following advantage: 1, caliper is when zero load, and translational speed is fast, can save time; Can be laborsaving when 2, compressing object, S22 * 2(TB23-66) drive screw with existing bench vice T26 * 5 compares if little helical pitch screw rod of the present utility model is elected as, calculates according to theory and can reduce hand-power or increase thrust 40%.

Below in conjunction with accompanying drawing the utility model is further described
With reference to Fig. 1, splined nut 8 is contained on the bottom faces of fixed caliper 3, and spline screw rod 4 is through in the splined nut 8, and fixedly be inserted in the cavity of little helical pitch nut 7 left part.Little helical pitch screw rod 5 right-hand members and little helical pitch nut 7 spin, and connect a back-moving spring 6 between the housing of the outer surface of little helical pitch nut 7 and moving caliper 2.Fig. 2 shows that bright locating piece 9 is fixed on the little helical pitch nut 7.Fig. 3 represents that the spline screw rod 4 and the jog of splined nut 8 are outer in the state of misfitting, and Fig. 4 represents that the spline screw rod 4 and the jog of splined nut 8 are in identical state.With reference to Fig. 5, Fig. 6, big helical pitch nut 10 is contained on the bottom faces of fixed caliper 3, big helical pitch screw rod 11 is spun in the big helical pitch nut 10, left end and little helical pitch screw rod 12 are fixedly connected, little helical pitch screw rod 12 left ends are profile of tooth garden nut shape, little helical pitch nut 14 rotation sets are on little helical pitch screw rod 12, its left end periphery has the corresponding groove of profile of tooth with little helical pitch screw rod 12 left ends, 15 activities of circumference pin are inserted in the groove of the tooth of little helical pitch screw rod 12 left ends and little helical pitch nut 14 left ends, flat spring 18 1 ends are pressed on the left side of circumference pin 15, accompany a butterfly spring 13 between little helical pitch nut 14 and the moving caliper 2, overcoat 16 is enclosed within on the little helical pitch nut 14 by the spline form, and overcoat 16 inboards have blocks circumference pin 15 toward the step 17 that moves right.
Operating process of the present utility model is as follows: scheme one, inhour rotary handle 1, little helical pitch screw rod 5 has a garden nut because of right-hand member, rotation ends and can drive spline screw rod 4 after the terminal and rotate to when locating piece 9 is collided with the housing of moving caliper 2 and end, at this moment, back-moving spring 6 is in tension, and spline screw rod 4 and splined nut 8 are in the state of Fig. 4, thereby spline screw rod 4 can slide in splined nut 8 moving caliper 2 is advanced rapidly, when clipping to workpiece, being about to handle 1 turns clockwise, the little helical pitch nut 7 of 6 of back-moving springs pulling drives spline screw rods 4 and is inverted to locating piece 9 and runs into the another side of moving caliper 2 housings and end, at this moment spline screw rod 4 is in Fig. 3 state with splined nut 8, and the spline screw rod can not move axially, and continues rotary handle 1 little helical pitch screw rod 5 and drives moving caliper 2 workpiece pressings.Scheme two, handle 1 turns clockwise and drives overcoat 16, overcoat 16 drives little helical pitch nut 14, because the left end groove of little helical pitch nut 14 and the tooth of little helical pitch screw rod 12 left ends are blocked by circumference pin 15, thereby little helical pitch screw rod 12 and big helical pitch screw rod 11 rotate along with little helical pitch nut together, thereby make moving caliper 2 fast moving.When jaw clips to workpiece, butterfly spring 13 is compressed, and little helical pitch nut 14 disengaging gardens week sells, and little helical pitch screw rod 12 and big helical pitch screw rod 11 stop operating, little helical pitch nut 14 continues to promote moving caliper 2 workpiece pressings around little helical pitch screw rod 12 rotations under overcoat 16 drives.The operation of unclamping workpiece and falling back is, inhour rotary handle 1, little helical pitch nut 14 counter-rotatings, workpiece unclamps, garden week pin snaps in the groove of little helical pitch nut 14 left ends again, at this moment, and little helical pitch nut 14, little helical pitch screw rod 12 and big helical pitch screw rod 11 become a unitary rotation again, thereby moving caliper 2 is fallen back fast.
