Fig. 1, Fig. 4, Fig. 5 are the sequential operation quick vice in the embodiment of the invention.
One, characteristics of the present invention are: (structural type with Fig. 1 illustrates)
1. for rapid axial moves moving jaw 2, and an end of screw mandrel 6 is designed to process the section screw mandrel 16 of several axial grooves on screw thread 12, nut 7 also respective design becomes section, and screw mandrel 16 can be slipped over from section nut 7 fast.
2. in order to lock screw mandrel 6, and to the workpiece application of force, lateral layout one block 9 of the screw thread 10 of section nut 7.When screw thread 12 meshed with screw thread 10, the side 11 of screw thread 12 was blocked and spline by the side 13 of block 9, and screw thread 10 makes screw mandrel 16 not move axially again, thereby pinned screw mandrel 16.At this moment, the motion between the screw thread of screw thread by screw mandrel 6 one ends and nut 1 just can be to the moving jaw application of force.
3. the sequential operation in order to realize being threaded into button and breaking away from, the rotation direction of the screw thread at the two ends of screw mandrel 6 is designed to opposite direction, design spring 5 and the pin 4 that prevents screw mandrel 16 back-out nuts 1.
In Fig. 1, fix a section nut 7 on the regular jaw seat 8, and on nut 7, offer the groove 17 that section screw mandrel 16 is passed through fast; For making screw mandrel 6 bear axial tension, the one end is designed to the screw mandrel 16 of section, and left-handed thread 12 is arranged on the screw mandrel 16, and the screw thread 10 on the nut 7 can mesh with the screw thread 12 on the screw mandrel 16; A block 9 that can make screw mandrel 6 splines and bear moment of torsion is also designed in the end of nut 7.
Right-handed nut 1 successfully cooperates installation with moving jaw 2, and is spacing with snap ring 3, establishes one at an end of nut 1 and can limit the pin 4 of the slewing area of screw mandrel 6, and make the spring 5 that produces the relative movement resistance between nut 1 and the screw mandrel 6.
The following describes the operating procedure of sequentially-operating quick vice:
(1) program of vice roll adjustment and clamping work pieces:
1, when the jaw 2 of the vice of Fig. 1 is in any aperture state, when the screw thread 12 of screw mandrel 16 is in the dead slot 17 of nut 7 screw threads 10, as the state of accompanying drawing 2.Workpiece is put in the position of rapid adjustment jaw 2, promotes moving jaw 2, and screw mandrel 16 slides in nut 7, and jaw 2 is fast near workpiece.
2, clockwise (eyeing right from the left side of Fig. 1) rotating nut 1, under the effect of the frictional force that spring 5 produces, screw mandrel 6 also rotates with nut 1.When screw thread on screw mandrel 6 the other ends 12 and screw thread 10 stagger and can not go into to detain the time, screw mandrel 16 be obstructed and can not rotates.At this moment, nut 1 still is rotated further, and screw mandrel 6 moves axially (left).When the thread of screw thread 12 is aimed at the thread groove of screw thread 10, just can go into button.Because nut 7 is left-handed, so screw thread 12 easier entering in the screw thread 10.When the side 13 of block 9 was run in the side 11 of screw thread 12, screw mandrel 6 can not rotate again, can not move axially again, as the state of Fig. 3.When if nut 1 rotates again, nut 1 drives moving jaw 2 relative to screw mandrel 6 rotations and moves clamping work pieces.
(2) vice unclamps the program of workpiece:
When the clamped condition of Fig. 3, rotate counterclockwise nut 1, the tangential force that the screw pair of screw mandrel 16 produces increases the resistance that rotates counterclockwise of screw mandrel 16, the tangential force that the screw pair of screw mandrel 6 and nut 1 produces helps the disengagement campaign of nut 1, and spring force is relatively very little when clamping, so nut 1 rotates and loosening workpiece earlier.After workpiece was loosening, spring 5 was in the frictional force that produces on the screw pair of nut 1 and screw mandrel 6 and sell under 4 the effect and make the screw thread 12 of screw mandrel 16 break away from screw threads 10.When the side 18 of block 9 was run in the groove side 19 of screw mandrel 16, screw mandrel 16 was obstructed and can not rotates, and after pin 4 was run into the screw thread starting point face 15 of screw mandrel 6, release process stopped.
The difference of the structural type of Fig. 5 and the structural type of Fig. 1 is: pin 4 is on the nut 14 of screw mandrel 16 left ends, and screw thread starting point face 23 is on screw rod 28; Nut in the explanation of Fig. 1 structural type 1, screw mandrel 6, starting point face 15 are changed into screw rod 28, nut 14, starting point face 23 respectively, be the explanation of Fig. 5 structural type.
Two, the characteristics of mechanism of the present invention are: (structural type with Fig. 4 illustrates)
1, the structural type of Fig. 4 is the structural type of Fig. 1 to be done suitably to revise to form when external force directly acts on screw mandrel 16.The modification content is: the rotation direction of the screw thread of two ends identical (being all left-handed among Fig. 4) on the screw mandrel 6: the internal thread that cooperates with screw mandrel 6 is arranged on the moving jaw 22; In regular jaw 24, fix rotary section nut 25; Spring 20 acts on section nut 25; Act on screw thread starting point face 26 on the screw mandrel 6 at the pin on the moving jaw 22 4; Snap ring 21 blocks spring 20; And design the bearing 27 of the frictional force of a nut 25 when reducing to unclamp.
2, programmed sequence of operations:
The program of A, vice roll adjustment and clamping work pieces
When the vice jaw is in any aperture state, and its screw mandrel 16 rapid adjustment jaw 22 positions when being in Fig. 2 state with section nut 25, put into work after, promote screw mandrel 16 and make moving jaw 22 fast near workpiece.Clockwise rotate screw mandrel 16, can not go into button if the screw thread of screw mandrel 16 12 staggers with screw thread 10, section nut 25 is stirred in the side 11 of screw mandrel 16, makes it to rotate with screw mandrel 16.Screw mandrel 6 rotates and is moved to the left with respect to nut 22, and spring 20 makes section nut 25 when rotating resistance be arranged, and this resistance helps into button.When screw mandrel 16 moves axially to the groove of thread of the accurate screw thread 10 of thread of screw thread 12, just can go into button.When side 13 that block 9 is run in the side 11 of screw thread 12 (Fig. 3 state), screw mandrel 16 can not rotate in section nut 25 again, can not axially move left again, when screw mandrel 16 is rotated further again, promotes moving jaws 22 and the application of force by screw mandrel 6.
B, the program when unclamping workpiece:
When screw mandrel 16 is in Fig. 3 state, because having, the tangential component that the screw thread 12 of screw mandrel 16 is subjected to hinders in screw thread 12 from screw thread 10, and the rotational resistance of section nut 25 is little, when rotating counterclockwise screw mandrel 16, moving jaw 22 is loosening earlier, the screw thread 12 of screw mandrel 16 breaks away from the screw thread 10 of nut 25 then, enters in the groove 17.Screw mandrel 16 is rotated further, and runs into pin 4 until screw thread starting point face 26 and ends when spacing.
The structural type of Fig. 5 also can be applicable on the structure of Fig. 4 by revising.
In a word, mechanism structure of the present invention is simple, reliable, is widely used, and can be applicable in the product of the quick roll adjustment of many need and the application of force.
