Abstract

A universal working pliers, the central part of the pliers body (7) is a hollow cylinder, and a static jaw (10) is arranged in the cylinder. The matching part of the static jaw (10) and the clamp body (7) is a cylindrical surface. An annular positioning groove (8) is arranged on the outer cylindrical surface, and a rectangular groove with a dovetail groove is arranged inside the annular positioning groove. The rectangular groove is provided with a rectangular screw nut (9). The movable jaw (14) penetrates into the static jaw (10), and the screw rod (16) is arranged in the movable jaw (14). The lower part of the clamp body (7) is a cylinder which is movably matched with the supporting seat (4). The center of the supporting seat (4) is provided with a cylindrical positioning shaft (20). The universal working pliers can rotate 360 degrees in the horizontal plane, the jaw can rotate 180 degrees around the horizontal shaft, and the pliers body can rotate 90 degrees in the vertical direction. The working pliers can be used for machine tools and common bench pliers.

Description

Universal working pliers

The utility model relates to a kind of working clamp, particularly a kind ofly both can use on lathe, can do the general-purpose working clamp of common bench vice again.

The working clamp that uses in producing at present has two kinds: a kind of is common bench vice, and another kind is the machine vice.Though two kinds of working clamps are widely used, all exist not enough.Mostly can only make unidirectional motion during the work of two kinds of vices, can not carry out multi-directional rotation, the jaw structure also mostly is fixed, to abnormity, complicated and have a part processing difficulty of angle.The multifunctional bench clamp (patent No. ZL92223492.2) that the Chinese patent communique is announced is though increase to some extent on function, and poor practicability, rigidity are also not enough, and operating accuracy is low, and movable clamp port lacks locking device, and functional reliability is not enough, and can't use on lathe.

The purpose of this utility model is the deficiency that overcomes the work on hand pincers, provides a kind of can the use on lathe to can be used as the novel omnipotent working clamp that common bench vice uses again.

The utility model is achieved in that omnipotent working clamp mainly is made up of chassis 19, supporting seat 4, caliper 7, fixed nip 10, movable clamp port 14 etc.Caliper 7 centres are a hollow cylinder.Fixed nip 10 is housed in cylinder, and fixed nip 10 is a cylindrical surface structure with the caliper mating part, has annular positioning groove 8 on the external cylindrical surface, and locatees with dog screw; Fixed nip 10 inside have the rectangular channel of band dovetail groove.Rectangle screw 9 is housed in the rectangular channel.Screw 9 is connected with fixed nip 10 usefulness screws 18.Movable clamp port 14 penetrates in the fixed nip 10, penetrates the cuboid of part for the band dovetail.Leading screw 16 installations are positioned in the movable clamp port 14 and pass screw 9.Spacing pressing plate 6,17 is equipped with at leading screw 16 two ends, compresses with screw 5,15 respectively, and the axis of caliper 7, fixed nip 10, movable clamp port 14 and the axis of leading screw 16 are parallel to each other.

Cylinder wedge lock cover 22,23 is equipped with at caliper 7 tops, and cylinder wedge lock cover 28,29 is equipped with at the movable clamp port middle part.The two pairs of lock sleeves are by screw rod 24 and 30 tensions, and it is vertical that screw axis and the axis of part fixed nip 10 with screw mandrel 16 that be locked are antarafacial.Fixed nip 10 has T-slot 11 with movable clamp port 14 tops, and the medial surface of each jaw is equipped with rectangle jaw mold insert 12,13.Caliper 7 bottoms are cylinder, with supporting seat 4 for movingly.Cylindrical end face has ring-type locating slot 21, and locatees with dog screw.Caliper 7 is compressed by 2 latch segments 26.Latch segment 26 is a rectangular shaped slider, and caliper 7 left and right sides respectively have one.Support spring 27 is equipped with in latch segment 26 inside, can move up and down.The axis of tie down screw 25 is vertical with horizontal plane.Supporting seat 4 inside are the face of cylinder, and cylinder locating shaft 20 is equipped with at the center.Supporting seat 4 is connected with chassis 19 usefulness bolt assemblies 1.Have ring-type T-slot 2 on the chassis.Reaching on the taper seat on fixed nip 10, chassis 19 on the arc surface of caliper dead ahead, all be shaped on graduation mark 3.

Characteristics of the present utility model are: omnipotent working clamp can return three-sixth turn in horizontal plane, and jaw can be around horizontal rotational shaft 180 degree, and vice body can return in vertical direction and turn 90 degrees.Indicate by scale the angle of revolution of three directions.Movable clamp port is equipped with the leading screw locking device, guarantees reliable operation.The jaw of working clamp is changeable jaw, is suitable for installation special-shaped, complex parts.This working clamp can be used for lathe, also can be used as common bench vice.

The utility model is described in further detail below in conjunction with embodiment shown in the drawings:

Fig. 1 is the profile of omnipotent working clamp;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is that the C of Fig. 2 is to view;

Fig. 4 is the B-B profile of Fig. 1.

Among the figure, 1-bolt assembly, 2-ring-type T-slot, 3-graduation mark, the 4-supporting seat, 5,15, the 18-screw, 6, the spacing pressing plate of 17-, the 7-caliper, the 8-annular positioning groove, 9-rectangle screw, 10-fixed nip, 11-T shape groove, 12,13-rectangle jaw mold insert, 14-movable clamp port, 16-leading screw, 19-chassis, 20-cylinder locating shaft, 21-ring-type locating slot, 22,23,28,29-cylinder wedge lock cover, 24,25, the 30-tie down screw, 26, latch segment, the 27-support spring.

Shown position is a general-purpose working clamp horizontal level state.Rotary screw 16 can make movable clamp port 14 move forward and backward.If horizontal plane rotation, but loose bolts group 1 are rotated in place back fastening bolt assembly 1 and get final product.If the vertical direction rotation can be become flexible two tie down screws 25, after the anglec of rotation puts in place, again two fastening getting final product of tie down screw.If around horizontal rotational shaft, can become flexible tie down screw 24, after the anglec of rotation puts in place again with its fastening getting final product.After workpiece clamps, must lock the tie down screw 30 of movable clamp port, rotate at work to prevent leading screw.When working special-shaped part, can utilize the T-slot on the sound jaw that changeable jaw is installed.Jaw mold insert 12,13 also can be made changeable.
