Abstract
The utility model discloses a kind of steel bushing of electric wrench and head capsule high stability location structure, including the steel bushing in head capsule and press-in head capsule head opening, steel bushing described in banding after the head capsule heating in medium frequency cooling, the steel bushing surface is provided with convex tendon, and the opening inner surface of the head capsule is provided with the neck being caught in for the convex tendon.Using device described in the utility model, head capsule can be fitted close with steel bushing, be not easy to loosen, and can prevent head capsule and steel bushing play.
Description
Technical field
The utility model belongs to assembly tool field, determines more particularly to a kind of steel bushing of electric wrench with head capsule high stability
Bit architecture.
Background technology
Electric wrench is broadly divided into impact wrench, torsion is cut spanner, constant torque wrench, corner spanner, angular spanner, hydraulic pressure and pulled
Hand, torque spanner, rechargeable electric wrench.Impact wrench is the instrument for screwing screw, bolt, fixture etc..Impact wrench
Generally steel bushing is pressed into head capsule, but due to be impossible to when steel bushing is processed with head capsule as design so just coordinating, one
Surely error is had, so abrasion is easily produced during press fitting, and after some time of use, matching somebody with somebody between head capsule and steel bushing
No longer close, generation loosening is closed, influences the performance of electric wrench.
The content of the invention
Problem to be solved in the utility model is：A kind of steel bushing of electric wrench is provided to tie with the positioning of head capsule high stability
Structure.
To solve the above problems, technical scheme provided by the utility model is:A kind of steel bushing of electric wrench is high with head capsule
Steel bushing in stability location structure, including head capsule and press-in head capsule head opening, banding after the head capsule heating in medium frequency cooling
The steel bushing, the steel bushing surface is provided with convex tendon, and the opening inner surface of the head capsule is provided with what is be caught in for the convex tendon
Neck.
Further：The neck both ends are equipped with the lead-in chamfered for being easy to convex tendon to be pressed into.
Further：The steel bushing is that surface polishes steel bushing, avoids the steel bushing and the head capsule mutual cooperation surface
Damage.
Further：Opening one end outwardly of the head capsule extends internally out the circle block edge relative with steel bushing end face,
Supported between the block edge and the end face of steel bushing and be provided with wool felt collar, prevent oil leak.
Further：The one end of the opening of the head capsule inwardly is fixed with the rubber ring to be offseted with the steel bushing, and sealing is anti-
Dirt.
Further：The neck inwall be provided with friction decorative pattern, be easy to cooling after convex tendon combined with neck more consolidate
Reliably.
Further：The convex tendon is axially arranged with multilayer along steel bushing, and the convex tendon in every layer is equiangularly spaced along steel bushing circumference
Arrangement.
The utility model has the advantages that:
Head capsule can be fitted close with steel bushing, be not easy to loosen, and can prevent head capsule and steel bushing play in the case of a high temperature.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Fig. 1 is the structural representation of the steel bushing with head capsule high stability location structure of this electric wrench；
Wherein:1. head capsule;2. steel bushing；3. wool felt collar；4. convex tendon；5. neck；6. rubber ring；7. block edge.
Embodiment
Embodiment:The steel bushing and head capsule high stability location structure of electric wrench as depicted, including head capsule 1 and press-in
Steel bushing 2 in the head opening of head capsule 1, the steel bushing 2 are that surface polishes steel bushing, avoid the steel bushing from being cooperated with the head capsule
The damage on surface.Steel bushing 2 described in banding after the heating in medium frequency of head capsule 1 cooling, the surface of steel bushing 2 is provided with convex tendon 4, described convex
Muscle 4 is axially arranged with multilayer along steel bushing, and the convex tendon 4 in every layer is along the equiangularly spaced arrangement of the circumference of steel bushing 2, and the institute of the head capsule 1
State opening inner surface and be provided with the neck 5 being caught in for the convex tendon 4, the inwall of neck 5 is provided with friction decorative pattern, and increase is described convex
Friction between muscle 4 and the neck 5, and the both ends of the neck 5 are equipped with the lead-in chamfered for being easy to convex tendon to be pressed into（Do not drawn in figure
Go out）.The convex tendon 4 is fitted close with the neck 5, prevents from being subjected to displacement between the head capsule 1 and steel bushing 2.The head capsule 1
Opening one end outwardly extends internally out the circle block edge 7 relative with steel bushing end face, is supported between the block edge 7 and the end face of steel bushing 2
The one end of opening inwardly provided with head capsule 1 described in wool felt collar 3 is fixed with the rubber ring 6 to be offseted with the steel bushing 2, reaches sealing
It is dust-proof to prevent oil leak.
For examples detailed above only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
People is can to understand content of the present utility model and implement according to this, can not limit the scope of protection of the utility model with this.It is all
The equivalent transformation done according to the utility model Spirit Essence or modification, should all cover the scope of protection of the utility model it
It is interior.
