Description

Double jaw vice

The utility model system is relevant with vice, more detailed it, refer to especially a kind of clamping firmly, keep the Double jaw vice of balance.Belong to the pincers worker utensil.

As Fig. 1, shown in Figure 2, it is known Double jaw vice 10, it is a pedestal 11, two sliding seats 12,13, two

jaw seats

14,15, a holder 16 and a screw rod 17 in one, this screw rod 17 is gone in pedestal 11 bottoms, and two sliding seats 12, has reverse internal thread in 13 and screw rod 17 can be screwed, this

jaw seat

14,15 are sheathed on two sliding seats 12 respectively, on 13, system belongs to the solid slide in angle,

jaw seat

14,15 inboards respectively are installed with jaw 141,151, system is with workpiece to be processed 18 during operation, 19 are placed in jaw 141,151 and middle holder 16 between, rotary screw 17, make two sliding seats 12,13 drive jaw seat 14 synchronously, 15 draw close to central authorities, and make jaw 141,151 with middle holder 16 make clamping workpiece 18,19 action;

Owing to should middle holder 16 be three blocks 161,162,163, be cascadedly combined with double-screw bolt 164, and being provided with a groove 111 on pedestal 11 inserts and locatees for middle block 162, one may be body in many ways when the workpiece of clamping, circular, during anomalistic object, holder 16 tilts and firm holding workpiece in causing easily, again because of two workpiece 18,19 place on the pedestal 11 simultaneously, two workpiece 18,19 volumes are not of uniform size, margin of error millimeter mm promptly might cause workpiece 18 on one side clamping, the workpiece 19 of the side situation of clamping not as yet in addition, and the inclination of holder 16 in the easier formation, and make known Double jaw vice 10 and impracticable, its holding workpiece stability deficiency, this point is treated improvements for the utmost point.

A kind of Double jaw vice of the utility model, its objective is: this Double jaw vice has firm middle holder, can be fit to the workpiece of circle, polygonal body, and when two workpiece volumes are inconsistent, still can do the action of fastening clamp workpiece via pressure adjustmenting mechanism, reach the effect of firm clamping.

A kind of Double jaw vice of the utility model, it is a holder and a screw thread in a pedestal, two slides, the two jaw seats,, this pedestal is provided with a chute for two slides location and slippage, respectively push away reverse internal thread in two slides and screw togather for screw rod, this two jaws seat respectively is placed on two slides, and jaw seat side is provided with jaw, when this screw rod of rotation, two jaw seats are center displacement in opposite directions with middle holder synchronously, and this pedestal is provided with a groove to go into middle holder, and this pedestal side is established plate lid and worn for screw rod;

It is characterized in that: holder respectively is provided with screw in vertical and horizontal level in this, but holder horizontal positioned in making, the spiral shell of standing is located on the groove of pedestal, establish a screw in the plate lid of this pedestal, this plate lid side device one pressure adjustmenting mechanism, this pressure adjustmenting mechanism contains the screwed pipe of one section external screw thread, the adjustment cap of one internal thread, two elastic elements and one compresses ring, this compresses the end that this screw rod was established and be positioned to the interior tool screw thread of ring, keep out protruding wall and replace in going into for two elastic elements and have in the screwed pipe, this screwed pipe screws in the screw of plate lid, adjust cap in the screwed pipe outward turning, one flexible member is resisted against the baffle ring of screw rod, and another flexible member is resisted against and compresses ring; In view of the above, when a jaw seat and middle holder clamping workpiece, can continue rotary screw, screw rod is dallied and displacement and move another jaw seat and make another workpiece of clamping in the jaw seat, this pressure adjustmenting mechanism, can be via the adjustment flexible member elasticity size of adjusting cap, and adjust screw displacement length, reach the purpose that two workpiece can be stablized clamping.

Wherein, this screw rod and compress ring system and be fixed at screw rod and compress on the ring by a little double-screw bolt is to combine and the tool one is rotated synchronously.

Wherein, this two elastic elements is a spring.

Wherein, in this two sided of holder vertically to level to respectively being provided with a V-type groove.

Wherein, in this two sides proximal portion of holder each can be provided with the L type short slot of a level.

Wherein, in this holder just, the back side can be provided with several screws, for the fixing location workpiece of doing of a location-plate.

Wherein, the inboard top end of the pawl seat of this jaw seat is provided with a L type short slot, and medial surface has burr, and lateral surface is the plane, and is locked in the jaw seat with double-screw bolt.

The utility model has the advantages that: the clamping that can be used for different shape even the size difference of two workpiece also can be used the pressure adjustmenting mechanism adjustment, makes the firmly clamping simultaneously of two workpiece of size with stable, and is simple to operate, easy to use.
