Description
Technical field
A kind of tool sleeve is the utility model is related to, more particularly, to a kind of high-performance aciculiform Multifunctional sleeve.
Background technology
Sleeve barrel tool refers to a kind of specific purpose tool that can be elastic, and in daily production and life, mechanical object exists
When maintenance and maintenance, it is often necessary to tighten more screw mechanism.Chinese patent discloses a kind of for loading and unloading bolt and nut
Instrument and its Multifunctional sleeve（Publication number：CN106312882A）, including multi-stage sleeve head and end caps, multi-stage sleeve head according to
It is secondary it is telescopic connect together, the length of prime collet head is less than the length for the rear class collet head being socketed with it, end caps
It is arranged on the end of afterbody collet head；During work, the Multifunctional sleeve is pressed onto on bolt or nut, the set of corresponding model
Cylinder head and bolt or nut coordinate, and the collet head smaller than bolt or nut model is pressed back into the collet head body of corresponding model
In；Dismantle or fasten after completing, the collet head automatic spring being pressed into；All sleeves at different levels in addition to afterbody collet head
Back-moving spring is respectively provided between head and end caps；Back-moving spring is cylindrical helical spring；In collet heads at different levels just
The front end of hexagonal hole as work functional hole with for loading and unloading corresponding bolt or nut, it is all in addition to afterbody collet head
The rear end of collet heads at different levels is machined with back-moving spring mounting hole；Two collet heads of adjacent socket, outer six prism of prime collet head
Wedge-shaped boss structure is machined with face, it is corresponding with being machined with the interior regular hexagon hole hole wall for the rear class collet head that it is socketed
Wedge-shaped groove structure；Afterbody collet head is the tube-in-tube structure in a cylindrical interior regular hexagon hole, and its rear portion is radially machined with
Fastener hole fastens end caps to coordinate with fastening bolt；End caps are a multidiameter structures；The big end external diameter of end caps
It is identical with the external diameter of afterbody collet head；The small end of end caps is processed into positive six prismsby structure, positive six prismsby structure it is outer
Boss structure is machined with cylinder to install with afterbody collet head to coordinate, and is also machined with the small end outer cylinder of end caps
The screw of radial direction with fastener hole, fastening bolt cooperation；Also be machined with the big end outer face of end caps mounting hole with phase
The pneumatic or electric tool assembling coordinated；Collet head has three-level.But this sleeve can not be applied to needle roller, and assembling
Shi Dingwei is more inaccurate, and instrument is easily beated when using, and assembly precision is poor.
Utility model content
The utility model is to provide a kind of high-performance aciculiform Multifunctional sleeve, and it is mainly solved present in prior art
Sleeve can not be applied to needle roller, and positioning is more inaccurate in assembling, and instrument is easily beated when using, assembly precision compared with
The technical problem of difference etc..
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
High-performance aciculiform Multifunctional sleeve of the present utility model, including sleeve body, described sleeve body inside are provided with
Square hole and hexagonal aciculiform hole, multiple needle trays are provided with the inwall in aciculiform hole, the tip of square hole is provided with arc groove.Square hole and pin
Shape hole is arranged together, and integrated level is higher.Needle tray can position a plurality of needles, prevent its movement.It can be risen using arc groove
To the effect finely tuned during assembling.
Preferably, the clamping slot of circular arc is provided with the inwall of described square hole.Clamping slot can be equipped with steel ball, can
With clamping tool.
Preferably, it is provided with rectangular channel on the inwall in described aciculiform hole.Needle body can be conveniently positioned using rectangular channel.
Preferably, being provided with locating slot on the inwall of described square hole, locating slot is trapezoidal, embedded with buffering in locating slot
The inwall of square hole is protruded in part, bolster outer end.Instrument can be positioned by bolster, the bounce of instrument when preventing from using.
Preferably, the inwall of described square hole the inner is provided with multiple knurling layers.It can be increased using multiple knurling layers
Frictional force with inserting instrument, prevents its abjection.
Therefore, the utility model can increase the positioning between each part and sleeve by multiple cell bodies and knurling layer
Precision, more accurate during assembling, instrument is not easy to beat during use, simple and reasonable for structure.
