A kind of quick bench vice
Technical field
The present invention relates to a kind of bench vice, relate in particular to a kind of quick bench vice.
Background technology
In mechanical field and other every profession and trade, what sold on clamping device that extensively adopts and the market all is traditional, constant for many years, the bench vice of guide screw matrix structure; This type bench vice mainly comprises base, operating grip, is connected with fixedly vice body on the base, and fixation clamps is connected with the folding of movable vice body on one's body through leading screw; Be connected with handle set on the operating grip; Drive moving caliper through the handle rotary screw rod and move forward and backward, realize the clamping of workpiece and loosen, it is slower that it regulates length between vices speed; Operator's labour intensity is big, and efficient is lower.
Summary of the invention
The purpose of this invention is to provide a kind of jaw can quickly opening and closing, the quick bench vice of high efficiency.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of quick bench vice comprises base, operating grip; Be connected with fixedly vice body on the base, fixation clamps is connected with movable vice body through leading screw on one's body, is connected with handle set on the operating grip; It is characterized in that: the left part of leading screw is designed with right-handed thread, and the right part of leading screw is designed with left hand thread, and screw thread is combined with left-handed nut on the leading screw in the movable vice body; Left-handed nut is slidingly connected through feather key and movable vice body horizontal plane, and the right-hand member of left-handed nut is fixedly connected with boss, and boss is positioned at the outside of movable vice body; The left part of left-handed nut is designed with circlip groove, and C shape circlip is housed in the circlip groove, and the right side of C shape circlip has pad; Be with the screw thread spring on the left-handed nut on pad right side; Left-handed nut is corresponding with left hand thread, and the right-hand member of leading screw has square knuckle, and square knuckle is fixedly connected with handle set through pin.
Advantageous effect of the present invention is: because this structure of the present invention, so use the jaw of the present invention can quickly opening and closing, increase work efficiency.

In the accompanying drawing: 1, fixing vice body; 2, movable vice body; 3, C shape circlip; 4, circlip groove; 5, spring; 6, feather key; 7, boss; 8, pin; 9, operating grip; 10, square knuckle; 11, left-handed nut; 12, left hand thread; 13, base; 14, right-handed thread.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:
The present invention is as shown in Figure 1, and a kind of quick bench vice comprises base 13, operating grip 9; Be connected with fixedly vice body 1 on the base 13, fixedly be connected with movable vice body 2 through leading screw on the vice body 1, be connected with handle set on the operating grip; It is characterized in that: the left part of leading screw is designed with right-handed thread 14, and the right part of leading screw is designed with left hand thread 12, and screw thread is combined with left-handed nut 11 on the leading screw in the movable vice body 2; Left-handed nut 11 is slidingly connected through feather key 6 and movable vice body 2 horizontal planes, and the right-hand member of left-handed nut 11 is fixedly connected with boss 7, and boss 7 is positioned at the outside of movable vice body 2; The left part of left-handed nut 11 is designed with circlip groove 4, and C shape circlip 3 is housed in the circlip groove 4, and the right side of C shape circlip 3 has pad; Be with screw thread spring 5 on the left-handed nut 11 on pad right side; Left-handed nut 11 is corresponding with left hand thread 12, and the right-hand member of leading screw has square knuckle 10, and square knuckle 10 is fixedly connected with handle set through pin 8.
Use the present invention, when shaking operating grip, make the leading screw rotation, thus drive activity vice body fast moving, and then the folding of control jaw, this structure can double the speed that movable vice body moves.
