When the higher steel wire of fixture grab tensile strength, material can be deformed in drawing process, so that fixture chucking power is insufficient, so as to cause
It stretches steel wire to skid, influences the reliability and accuracy of experimental result, and in order to make material is non-slip to need to increase the power clamped
Degree, the tooth form for increasing dynamics rear jig surface can more be goed deep into, and steel wire is caused to be broken in the deep position of tooth form, influence test knot
Fruit, while cannot achieve the height of flexible alignment jig.
The invention provides the following technical scheme: steel wire pulling force grip of testing machine, including support column, workbench and clamp machine
Structure, the support column are fixedly connected with workbench by lower left side, and the upper end middle position of the workbench is fixedly connected with fixed block,
The upper end of the fixed block is fixedly connected with sleeve, and the right end of the sleeve is fixedly connected with spanner, and the center of the sleeve is passed through
It wears and sets lifting screw, the upper end of the lifting screw is fixedly connected with fixed plate, and the upper end of the fixed plate is fixedly connected with clamping
Part, the clamp mechanism include disk, left fixture and right fixture, and the left upper end of the clamping element is flexibly connected left fixture, described
The surrounding of the right fixture of clamping element upper right side flexible connection, the left fixture and right fixture is flexibly connected by fastener with disk.
Preferably, the quantity of the spanner is four, and is oppositely arranged the left and right sides for being distributed in the sleeve two-by-two.
Preferably, the workbench, support column, fixed block, clamp mechanism, sleeve, lifting screw, fixed plate, clamping element
Quantity be two.
Preferably, the inner wall of the sleeve is provided with screw thread.
Preferably, the lifting screw can be along sleeve lining oscilaltion campaign.
Preferably, the side of the left fixture and right fixture is provided with several teeth, and the left fixture and the right side
The length of fixture is 50cm, and the depth of the tooth is 1mm.
Be compared with the prior art, the present invention have it is following the utility model has the advantages that
The depth of tooth is reduced, is increased by lengthening the contact surface of left fixture and right fixture suitable for steel wire pulling force grip of testing machine
The quantity of tooth is increasing clamping dynamics and is increasing the same of frictional force in this way to realize the quantity of increase tooth to increase contact point
When can reduce tooth steel wire deformation is caused fracture influence, can also be effectively relieved steel wire skid the phenomenon that, secondly go up and down
The height of screw rod adjustable left fixture and right fixture, improves the flexibility and accuracy of steel wire pulling force grip of testing machine.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, steel wire pulling force grip of testing machine, including support column 1, workbench 2 and clamp mechanism, support column 1
Be fixedly connected with workbench 2 by lower left side, the upper end middle position of workbench 2 is fixedly connected with fixed block 3, the upper end of fixed block 3
It is fixedly connected with sleeve 4, the right end of sleeve 4 is fixedly connected with spanner 5, and the center of sleeve 4 is through setting lifting screw 6, lifting
The upper end of screw rod 6 is fixedly connected with fixed plate 11, and the upper end of fixed plate 11 is fixedly connected with clamping element 12, clamp mechanism include disk 7,
Left fixture 8 and right fixture 9, the left upper end of clamping element 12 are flexibly connected left fixture 8, and 12 upper right side of clamping element is flexibly connected right fixture
9, the surrounding of left fixture 8 and right fixture 9 is flexibly connected by fastener 10 with disk 7, and the quantity of spanner 5 is four, and two-by-two
It is oppositely arranged the left and right sides for being distributed in sleeve 4, workbench 2, support column 1, fixed block 3, clamp mechanism, sleeve 4, lifting screw
6, fixed plate 11, the quantity of clamping element 12 are two, and the inner wall of sleeve 4 is provided with screw thread, and lifting screw 6 can be along set
4 inner wall oscilaltion campaigns of cylinder, are acted on using the mutual cooperation between them, adjust left fixture 8 and right folder so as to realize
The side of the height of tool 9, left fixture 8 and right fixture 9 is provided with several teeth, and the length of left fixture 8 and right fixture 9 is
50cm, the depth of tooth are 1mm, are acted on using the mutual cooperation between them, to realize that the quantity for increasing tooth contacts to increase
Point can reduce the influence that tooth causes fracture to steel wire deformation while increasing clamping dynamics and increasing frictional force in this way,
The phenomenon that steel wire skids can also be effectively relieved.
When work, user pushes hard spanner 5 first and rotates with moving sleeve 4, adjusts so as to drive lifting screw 6
At this moment steel wire is manually placed at left fixture 8 and right folder when required height is arrived in adjusting by the height of left fixture 8 and right fixture 9
