Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail.
The pincers that bend for installing anti-rotation sheet are installed by Z-shaped jaw 1 and the combination of jaw 6 of bending；Wherein,
Z-shaped jaw 1 includes two pull rods 9, and spacing is kept between pull rod 9 (to install but anti-rotation sheet to be bended for being inserted in
Screw pair)；The same end of two pull rods 9 is fixedly connected with bending jaw 8, and the front end of bending jaw 8 is bent simultaneously towards pull rod
Form the gib head of acute angle shape；It is equipped with the protruding portion reversed with the gib head of bending jaw 9 in the other end of two pull rods 9, makes to clamp
Whole mouth is in zigzag, and pin hole 10 is arranged at the center of protruding portion；
The jaw 6 that bends includes pincers 7 and jaw ontology in T shape, and the front end of jaw ontology has bending shape in obtuse angle
The gib head 12 of shape, the rear end of jaw ontology are fixedly connected with pincers 7；Vertical with obtuse angle overbending direction lead to is equipped on jaw ontology
Hole 13, pin shaft 5 pass through pin hole 10 and through-hole 13, and the jaw 6 that makes to bend is movably arranged between two pull rods 9 of Z-shaped jaw 1 and two
The gib head of person is oppositely arranged, collectively constitute outer narrow inner width wedge-shaped jaw (as shown in fig. 6, the right be main view, the left side is left view
Figure).
Consider to be connected firmly, notch can be set in the front end of pull rod 9, protrusion is set on bending jaw 8, is protruded
Portion's insertion notch simultaneously realizes being fixedly connected for bending jaw 8 and pull rod 9 by way of inlaying group weldering.In addition, in jaw ontology
Tail portion setting nick shaped pincers socket 11, pincers are real socket 11 and by way of inlaying group weldering 7 end insertion pincers
Existing jaw ontology is fixedly connected with clamping 7.Assuming that the distance of 12 end of gib head of jaw ontology to through-hole 13 is l1, clamp 7
The distance of tail end to through-hole 13 is l2；For laborsaving consideration, l2It at least should be l120 times.
Specific example is as follows:
The pincers that bend of the invention are using biasing layout (see Fig. 3), and Z-shaped jaw 1 is welded using inserted group, and one end is made
Gib head, the other end are drilled with pin hole 10, and insertion pin shaft 5 and 6 activity of jaw of bending form balance pivot on pin hole 10, and gib head is used for will
Anti-rotation sheet aerofoil bends molding (see Fig. 4)；It bends 6 head t shape (see Fig. 5) of jaw, middle part is drilled with through-hole 13, tail portion insert
There are pincers 7 and be welded and fixed, similar crowbar after combination, through-hole 13 and gib head distance are very short, through-hole 13 to the tail end distance clamped 7
It is very long, through-hole 13 as " crowbar " fulcrum and form high magnification numbe lever ratio.It can be the manual force F1's of operator
Under effect, several tons of pressure are formed to the aerofoil of anti-rotation sheet, two gib heads gradually collapse, and anti-rotation sheet bending is forced to be held tightly.
Z-shaped jaw 1 is inlayed by bending jaw 8 and two pull rods 9 group to be welded, and one end of bending jaw 8 is used with gib head
It is formed in anti-rotation sheet aerofoil, the reversed protruding portion end of 9 tail end of pull rod is drilled with pin hole 10, for assembling the jaw 6 that bends；Two pull rods 9
Between inner space convenient for being inserted in screw pair 3.
The jaw 6 that bends is an overall structure, and by being machined, the pincers of tail portion are socket 11 for assembling pincers
7, embedded structure can increase fusion length, improve warping resistance ability；Gib head 12 is for bending and holds anti-rotation sheet aerofoil tightly,
Through-hole 13 is assembled into the pincers that bend for being inserted into pin shaft 5 and Z-shaped jaw 1, and pin shaft 5 can be fixed with axle bumper；Pin shaft 5 is also lever simultaneously
The fulcrum of power, active force transmit Z-shaped jaw 1 by pin shaft 5；Z-shaped jaw 1 and 6 phase of jaw of bending under the action of directed force F 1
Interaction, two opposite stress of gib head form the gesture for doubles team, bend molding up to by anti-rotation sheet 4.
