The specific embodiment
At first, referring to Fig. 1 to Fig. 4, the vice jaw structure that the utility model can make workpiece sink, this vice has a body 10, and these body 10 1 ends form a fixed jaw 11, and opposing parallel is convexly equipped with the screw part 13 that a spiral shell is established a driving screw 12 but other holds then, the then sliding movable jaw 14 of establishing between this fixed jaw 11 and this screw part 13, by rotating this driving screw 12, make this movable jaw 14 to move, to reach the effect of holding workpiece to these fixed jaw 11 directions.
Wherein, it should be noted that, this fixed jaw 11 is installed with a combination block 20 respectively with the relative inner edge surface of this movable jaw 14, the block that this combination block 20 generally is rectangle, the two ends of this combination block 20 spiral shell respectively are provided with a location bolt 21, and the end face spiral shell of this combination block 20 is provided with at least two and adjusts bolt 22, and the inner top surface of this combination block 20 is provided with most the oblique guide holes 201 of equidistantly arranging shape, be equiped with an elastic parts 23 respectively in each oblique guide hole 201, in present embodiment, this elastic parts 23 is springs, and be equiped with cylindrical without exception floating part 24 respectively in each oblique guide hole 201, be subjected to the pushing and pressing of each elastic parts 23 under each floating part 24 normality, protrude the end face and the side of this combination block 20, and the oblique tangent plane 241 that is provided with of the end face of each floating part 24, this tangent plane 241 is parastate with the side of this combination block 20, and the end face of this floating part 24 is parallel with the end face of this combination block 20, and this floating part 24 has the dissected valley 242 of an arc with respect to the bottom surface of this tangent plane 241, and the bottom surface of this floating part 24 has a profile groove 243, makes this profile groove 243 and these dissected valley 242 cross-shaped attitudes;
In addition this combination block 20 side of differing from each oblique guide hole 201 has a sunken groove 202 that is horizontally set, it is ccontaining for a gear-stopping bar 25 to fall into groove 202, the two ends of this gear-stopping bar 25 have a location division 251 respectively, in present embodiment, this location division 251 is grooves, it perhaps is a hole, each location division 251 is supported for each bolt 21 spiral shell respectively, and this gear-stopping bar 25 is positioned in this sunken groove 202, and the end face of this gear-stopping bar 25 is pushed by this two adjustment bolt 22, and gets so that each floating part 24 is adjusted level heights;
This gear-stopping bar 25 is convexly equipped with out a projection 252 respectively with respect to dissected valley 242 1 sides of each floating part 24 in addition, this projection 252 is positioned in this dissected valley 242, and the bottom surface that makes this gear-stopping bar 25 is abutted against on the profile groove 243 of each floating part 24, make each floating part 24 be able to be colluded and hold the location, not the elastic force of reason elastic parts 23 and deviating from.
Please cooperate and consult Fig. 5, workpiece 30 is positioned between the fixed jaw 11 and movable jaw 14 of vice, the user makes movable jaw 14 to move to fixed jaw 11 directions, to reach the effect of holding workpiece 30 by rotating driving screw 12; When movable jaw 14 promotes workpiece 30 to fixed jaw 11 direction clampings, can impose horizontal horizontal thrust, one side of workpiece 30 is abutted against to the medial surface of the combination block 20 of fixed jaw 11, at this moment, because of workpiece 30 abuts against in the tangent plane 241 of the floating part 24 of combination block 20, so the tangent plane 241 to floating part 24 imposes lateral pressure, after the elastic force of the elastic parts 23 of fixed jaw 11 to be overcome and movable jaw 14, each floating part 24 is moved down, and while elasticity of compression assembly 23, and because of floating part 24 moves down, the related pushing force that makes gear-stopping bar 25 lose each floating part 24 also moves down synchronously; And because of fastening the close tangent plane 241 that is affixed by each floating part 24 in the both sides of workpiece 30, make workpiece 30 and floating part 24 between the two, be absolute position way of contact configuration, so when floating part 24 moves down, also driving workpiece 30 simultaneously descends, closely abut against end face (as shown in Figure 6) until the bottom surface of workpiece 30, compel the power of holding to keep splendid clamping, and exempted the unnecessary work of knocking in vice jaw.
And, workpiece 30 bottom surfaces and vice jaw end face closely abut against state because of being, at this moment, the user is if continue to rotate driving screw 12, can make the phenomenon that produces relative slip between floating part 24 and the workpiece 30, thus, can too do not pushed with the face that is held of guaranteeing workpiece 30, and produced the facts that the surface crushes or is out of shape.
In addition, referring to Fig. 4, a because side of combination block 20 installing location one gear-stopping bar 25, and the projection 252 of gear-stopping bar 25 is positioned in the dissected valley 242 of floating part 24 bottom surfaces, so prevented floating part 24 phenomenon that rotates really, with the tangent plane 241 and the side of combination block 20 of the guaranteeing floating part 24 capable state of keeping tie forever; In addition, the bottom surface of gear-stopping bar 25 abuts against on the profile groove 243 of each floating part 24, make each floating part 24 be able to be colluded by gear-stopping bar 25 and hold the location, and the elastic-restoring force of each elastic parts 23 of reason not causes floating part 24 to deviate from combination block 20.
In addition, the user is utilized each adjustment bolt 22 that tunes combination block 20 end faces, make and respectively adjust bolt 22 pushing gear-stopping bar 25 downwards, and abut against on the profile groove 243 of each floating part 24 because of the bottom surface of gear-stopping bar 25, so make gear-stopping bar 25 be driven whole floating part 24 to bottom offset, and get so that each floating part 24 is adjusted to identical level height, make whole adjustment mode simply easy.
Comprehensive the above as can be known, the vice jaw structure that the utility model can make workpiece sink is subjected to abutting against the tangent plane in floating part after the vice jaw clamping by workpiece, makes workpiece be driven by floating part and sinks automatically, and have splendid clamping and compel the power of holding.
