Description
Technical field
The utility model belongs to punching machine sided nut field, and in particular to a kind of lathe side screw nut loosing prevention device.
Background technique
Currently, using screw connector in most mechanical equipments, when being hit, the connection bolt for vibrating position is easy pine
Normal operation that is dynamic and influencing mechanical equipment.As in punching apparatus, only workbench fixed with fastening nut, this knot at present
Structure can make host, workbench generation vibration loosen fastening nut, so that host deformation be made to influence life in pressure process repeatedly
Produce the qualification rate of part.
Summary of the invention
Aiming at the shortcomings in the prior art, the utility model provides a kind of lathe side screw nut loosing prevention device, to solve
The problem of existing punching machine side nut is easy to loosen in long-time punching course, and punching precision is caused to reduce, high rejection rate.
The utility model is achieved through the following technical solutions.
The side setting of a kind of lathe side screw nut loosing prevention device, including machine body, the machine body is tightened
The nut of workbench, upper and lower two, the nut are one group, pass through wirerope between top nut and lower nut and bundle connection, institute
It is welded with two grade bolts on the nut stated, concave shape slot, the side of the concave shape slot are provided on two grade bolts
Through slot is connected, the wirerope is wound at the fixed block of concave shape front of the slot, and the both ends extracted after winding cross one another volume
It is drawn around from through slot, reaches up to lower nut, reached from concave shape slot from lower nut second level nut lower part, separate and twine originally
Around wirerope both ends, one end bypasses out of concave shape slot, and the other end finally merges in character cut in bas-relief from the external mistake of concave shape slot
The outside of shape slot, both ends cross one another winding, are integrally wound on spud pile after winding.By special wire rope fixing device,
The fixation for completing nut, reduces the loosening of nut, and wirerope is replaceable, substantially increases production efficiency and precision.
Preferably, being provided with annular groove on the spud pile.Increase with the friction of wirerope, that reduces loosening can
It can property.
Preferably, the concave shape slot and through slot position inside top nut and lower nut are symmetrical.So that wirerope inclines
It sideling winds, is conducive to the tension of wirerope.
Compared with prior art: by special wirerope binding mode, realizing the fixation between two nuts, prevent pine
Dynamic, effect is good, long service life.

Specific embodiment
With reference to the accompanying drawing with specific embodiment, the utility model is described further.
The side setting of a kind of lathe side screw nut loosing prevention device, including machine body, the machine body is tightened
The nut 1 of workbench, described about 1 two, nut is one group, is connected between top nut and lower nut by the binding of wirerope 4
It connects, two grade bolts 2 is welded on the nut 1, are provided with concave shape slot 5, the concave shape on two grade bolts 2
The side of slot 5 connects through slot 3, and the wirerope 4 is wound at the fixed block of 5 front end of concave shape slot, two extracted after winding
End crosses one another winding from the extraction of through slot 3, reaches up to lower nut, reaches concave shape slot from lower nut second level nut lower part
At 5, the both ends of the wirerope of winding originally are separated, one end bypasses out of concave shape slot 5, and the other end is from the outside of concave shape slot 5
It crosses, finally merges in the outside of concave shape slot 5, both ends cross one another winding, are integrally wound on spud pile 41 after winding, described
Annular groove is provided on spud pile 41, the concave shape slot 5 and 3 position of through slot inside top nut and lower nut are symmetrical.
During the installation process, nut 1 is installed first, after the installation is completed, second level nut 2 is welded, takes out a steel wire at this time
Rope 4, wirerope 4 is inserted in the fixed block of upper end, and both ends come out from two of concave shape slot 5 respectively, out after reach through slot
3, cross winding is carried out in through slot 3, is wound into a strand, is gone out from the tail portion of through slot 3, continues to wind, and reaches the spiral shell of lower section
Mother 1 stops from the concave shape slot 5 on right side from below after the tail portion winding of the second level nut 2 of nut 1, a strand is continued at this time
Both ends are split up into, one end enters in concave shape slot 5, and the other end is from the outside through mistake, at the lower section for reaching 41 position of spud pile jointly.
Cross winding is continued at both ends at this time, is wound into a strand, is integrally wrapped on the annular groove of spud pile 41, and
It knots, no matter how punching machine uses, and any loosening will not all occur for nut, because the position of upper lower nut is defined,
Unless wire cable rupture or loosening, more change steel rope.
The protection scope of the utility model includes but is not limited to embodiment of above, and the protection scope of the utility model is to weigh
Subject to sharp claim, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that are each fallen within
The protection scope of the utility model.
