End cap 5 is arranged with the cylindrical step hole of matching with cruciform slot screw 6 for a pair; A pair cruciform slot screw 6 is after passing above-mentioned a pair cylindrical step hole, and a pair axial threaded hole be provided with fixed caliper 4 tail end again matches, thus end cap 5 is packed in the tail end of fixed caliper 4.
The inner face of end cap 5 is provided with the feather key 5-1 be structure as a whole with it, and this feather key is axial projection, can match with the gathering sill that fixed caliper 4 and moving caliper 3 are provided with separately.The effect of feather key 5-1: one is that moving caliper 3 can carry out axis movement fast along above-mentioned feather key 5-1 by the gathering sill 3-2 which is provided with; Two be ensure screw mandrel 1 and moving caliper 3 and fixed caliper 4 and end cap 5 can together with turn round.
Screw mandrel 1 and moving caliper 3 and fixed caliper 4 and end cap 5 can within the scope of vertical plane 0 ~ 360 ° together with turn round, thus the suitable operating angle of adjustment workpiece, is convenient to bench work; Revolution carries out pre-determined bit locking by the set lever 15 pairs of fixed calipers 4 being arranged on bearing 14 side after adjusting to the right place, thus screw mandrel 1 can not be turned round with end cap 5 with moving caliper 3 and fixed caliper 4.Chassis can be fixed on work top, and bearing 14 can rotate within the scope of 0 ~ 360 °, horizontal plane, after adjusting to the right place, is locked on chassis by bearing 14 by another set lever being arranged on rest base.
As shown in Figure 1 and Figure 2, this snap-action device comprise end cap 5, hand 12, rotating shaft 11, torsion spring 13, screw 8, screw is 8-1, spring 9, screw mandrel 1; Wherein:
As shown in Figure 1 and Figure 2, the outer face of end cap 5 is provided with fin 5-3, this fin 5-3 is the axial projection in circular arc, and the outer circumference surface of above-mentioned axial raised outer circumference surface and end cap is tangent.Be provided with for passing screw the radial direction through hole of 8-1 and the axial screw for fixed dam 7 in one end of fin 5-3; The other end of this fin 5-3 and hand should be less than the tiger's jaw width of a pincers worker hand the distance between 12 movable one end, meet pincers worker manual requirement.
As shown in Figure 2, the outer circumference surface of end cap 5 is provided with the lug 5-2 radially extended; This lug 5-2 is provided with the axial screw matched with rotating shaft 11.This rotating shaft 11 is screw, and the axial screw that itself and lug 5-2 are provided with matches.
As shown in Figure 1 and Figure 2, hand is curved shape 12, and its one end can be movable, and its middle corner is arranged on lug 5-2 by rotating shaft 11, and its other end is provided with, with screw, the outer end of 8-1 is formed the movable opening coordinated.This hand 12 for controlling screw-threaded engagement between screw 8 and screw mandrel 1 and thread separation state.
Torsion spring 13 is arranged with in the rotating shaft 11 between 12 and lug 5-2 at hand.One end of this torsion spring 13 is inserted in the through hole that screw is provided with 8-1 outer end, and torsion spring 13 can also prevent hand from the U-shaped opening on 12 and screw are departed from the outer end of 8-1; The other end of this torsion spring 13 abuts against hand on the lateral surface of 12 movable one end.
The effect of torsion spring 13 and compression spring 9 is: unclamp hand 12 time, compression spring 9 and torsion spring 13 can order about fast hand 12 automatic Rapid resets, torsion spring 13 can also increase hand handle tightly speed sense and handle effect; Meanwhile, compression spring 9 can also order about screw 8-1 and screw 8 Rapid reset automatically, realizes the screw-threaded engagement between screw 8 and screw mandrel 1.
As shown in Figure 1 and Figure 2, screw 8 and the screw be arranged on outside it are structure as a whole 8-1, and the two is disposed radially, and perpendicular with the screw mandrel 1 arranged vertically.
Be provided with arc surface at the inner end of screw 8, above-mentioned arc surface is provided with the internal thread be meshed with the external screw thread on screw mandrel 1.The threaded portion of this screw 8 is corresponding with the gathering sill 3-2 on moving caliper 3, and this screw 8 is meshed with screw mandrel 1 through the gathering sill 3-2 on moving caliper 3.The width of screw 8 is slightly less than the width of the gathering sill 3-2 on moving caliper 3.
The screw thread that screw 8 with screw mandrel 1 are provided with is the nonstandard saw-tooth thread of negative angle, and the main stress face axial section of screw screw thread is α leaning angle, and α leaning angle is 1 ° ~ 10 ° scopes; Wire rod thread front end axial section is α leaning angle, and α leaning angle is 1 ° ~ 10 ° scopes, and wire rod thread rear end axial section is the large oblique angle of β, and β is 20 ° ~ 60 ° scopes.
Screw is cylindrical the inner of 8-1, and its position between fin 5-3 and screw 8 is arranged with spring 9, and this spring 9 is compression spring; This screw is flat-shaped structure the outer end of 8-1, and it inserts hand in the U-shaped opening on 12, and the two formation activity coordinates; At screw, the outer end of 8-1 is also provided with the through hole for inserting torsion spring 13 one end.
As shown in Figure 1, at screw 8 and screw, the arranged outside of 8-1 and spring 9 is had baffle plate 7, one end of this baffle plate is fixed on fin 5-3 by soket head cap screw 10, and above-mentioned soket head cap screw 10 and fin 5-3 are provided with axial screw and match; The other end of this baffle plate 7 is circular arc, forms matched in clearance with the cylindrical of screw mandrel 1.The effect of baffle plate 7 is, when fast moving caliper 3 carries out larger distance quick mobile, can protect screw 8 and spring 9, prevents from being subject to the external impacts such as packing ring and cause damaging.
The course of work of snap-action multipurpose vice of the present invention is as follows:
See Fig. 1, Fig. 2, pincers worker hand pins fin 8-1, inwardly pulls hand 12 simultaneously, and this hand 11 rotates the other end of 12 around the shaft, drives screw 8-1 and screw 8 outwards movement simultaneously, realizes the thread separation between screw 8 and screw mandrel 1.At this moment, by Quick push/pull moving caliper 3, the fast clutch of moving caliper 3 and fixed caliper 4 can be realized, and then realize Quick-clamped and unclamp workpiece.
Decontrol hand 12, under the effect of spring 9 and torsion spring 13, this hand 11 rotates and rapid resets around the shaft 12; Meanwhile, screw 8 and screw under the effect of spring 9, move inward reset 8-1 rapidly, and make screw 8 and screw mandrel 1 be in screw-threaded engagement state.At this moment, rotate driving lever 2 and screw mandrel 1, moving caliper can be driven to move at a slow speed.
In addition, when screw 8 is in screw-threaded engagement state with screw mandrel 1, does not increase any action, can optionally moving caliper 3 be advanced fast to fixed caliper 4 direction yet.
