Description
Technical field
It the utility model is related to hardware spanner technical field, and in particular to a kind of fast assembling-disassembling round nut sleeve.
Background technology
At present in big-and-middle diesel engine manufacture, the moment of torsion of many nut checks is very big, all using hydraulic elongator to nut
Locked；Used for the ease of hydraulic elongator, bolt locking nut profile is designed to circle；Round nut is drawn with hydraulic pressure
To stretch before device locks to nut, round nut needs pretension, but existing spanner and sleeve, torque spanner can not all use,
The installation pretension of round nut and dismounting can only operate by hand, it is impossible to ensure the pretension precision of nut, manual operation installation is in advance
Tight and dismantlement work intensity is big, efficiency is low.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of fast assembling-disassembling round nut sleeve.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
A kind of fast assembling-disassembling round nut sleeve, described fast assembling-disassembling round nut sleeve, which has, to be nested with and need to dismount circle
Elastane thread set on shape nut；The bottom of the elastane thread set is the circular cone stage body in flaring footpath from top to bottom；Elastane thread
Covering, there is the axial pass trough being uniformly distributed along the circumference to form on the periphery of the circular cone stage body need to dismount round nut to clamp
Elastic clamping jaw；The middle part of the circular cone stage body upper surface has the hollow cylinder that raises up, the hollow cylinder it is outer
Wall has external screw thread；The middle part of the cylinder upper surface is outer hexagonal structure body；The center tool of the outer hexagonal structure body
There are four square holes being used cooperatively with torque spanner；Described fast assembling-disassembling round nut sleeve, which also has, to be nested with elastane thread set
The screw fastening tight set in outside；Described screw fastening tight set is tubular, and bottom and the elastane thread of the screw fastening tight set cover bottom
Circular cone stage body coordinate；The top of the screw fastening tight set is connected with described elastane thread external threading.
The top of the screw fastening tight set outside wall surface is machined with the annular knurl for being easy to handmade rotary.
The utility model proposes a kind of fast assembling-disassembling round nut sleeve efficiently solve the pretension precision of round nut
Low, the problem of dismantlement work intensity is big, efficiency is low.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that elastane thread covers in the utility model.
Fig. 3 is the structural representation of screw fastening tight set in the utility model.
In figure：1st, elastane thread set, 2, screw fastening tight set, 3, round nut need to be dismounted.
Embodiment：
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of fast assembling-disassembling round nut sleeve, described fast assembling-disassembling round nut sleeve, which has, to be nested with
The set of the elastane thread on round nut 1 need to dismounted；With reference to Fig. 2, the bottom of the elastane thread set 1 is flaring footpath from top to bottom
Circular cone stage body；Elastane thread cover on the periphery of the 1 circular cone stage body there is the axial pass trough that is uniformly distributed along the circumference to form to
The elastic clamping jaw of round nut need to be dismounted by clamping；The middle part of the circular cone stage body upper surface has the hollow cylinder to raise up
Body, the outside wall surface of the hollow cylinder have external screw thread；The middle part of the cylinder upper surface is outer hexagonal structure body；It is described
The center of outer hexagonal structure body has four square holes being used cooperatively with torque spanner；Described fast assembling-disassembling round nut sleeve is also
With the screw fastening tight set 2 being nested with the outside of elastane thread set；With reference to Fig. 2, described screw fastening tight set is tubular, the screw thread
The circular cone stage body of the bottom of lock sleeve and elastane thread set bottom coordinates；The top of the screw fastening tight set and described thread bullet
Property external threading connection.
The top of the screw fastening tight set outside wall surface is machined with the annular knurl for being easy to handmade rotary.
The utility model is in use, the utility model is inserted on round nut, the elastane thread set 1 of round nut sleeve
Bottom is that thin-walled elastic claw inner circle stepped hole is caught with round nut external diameter and upper surface, is turned with hand conrotatory on round nut sleeve
Screw fastening tight set 2, screw fastening tight set 2 move down on elastane thread set 1 so that the bottom of screw fastening tight set 2 is cylinder inner cone
Taper face is compressed outside the bottom thin-walled elastic claw of elastane thread set 1, and it is thin-walled bullet to cause elastane thread to cover 1 bottom
Property pawl deformation and uniform shrinkage, to round nut clamp, it is quick to round nut by electric and pneumatic instrument and ratchet spanner
Installation and dismounting；It is upward on elastane thread set 1 with screw fastening tight set 2 on hand reverse rotation round nut sleeve, screw fastening tight set 2
It is mobile so that the bottom of screw fastening tight set 2 is that cylinder inner conical surface enters to taper face outside the bottom thin-walled elastic claw of elastane thread set 1
Row loosens, and causes elastane thread to cover 1 lower deformation thin-walled elastic claw and restores, unclamps and round nut is clamped.This practicality is new
A kind of round nut sleeve of type can be according to round nut outside dimension, the product of design standard series, and then carries out different model
Round nut is rapidly assembled and disassembled.
