Abstract
The utility model discloses a kind of fluting cylindrical bolt tool special for dismounting, its structure is：The top surface of sleeve is provided with two semi-circular recesses, is provided with a straight rib between two grooves, and the inner side of sleeve is provided with a foursquare cavity.The instrument of fluting cylindrical bolt dismounting is supported the use with ratchet spanner, and ratchet spanner is matched with two semi-circular recesses of extracting tool, and the foursquare cavity of extracting tool is corresponding with the fluting cylindrical bolt of engine lubricating oil pressure maintaining valve.This instrument solves the problems, such as during the assembly or disassembly of larger fluting cylindrical bolt during engine assembly it is impossible to ensure moment of torsion torque requirement.Select different foursquare cavity dimension so that it may assembly or disassembly is carried out to the fluting cylindrical bolt of different size.And this specific purpose tool structure is simple, easy to use, is easy to processing and manufacturing, has good practical value.
Description
Technical field
This utility model belongs to mechanical maintenance tool in use and in particular to a kind of be exclusively used in what cross-notching cylindrical bolt was dismantled
Instrument.
Background technology
Fluting cylindrical bolt is a kind of very common securing member, is widely used in machinery industry.The function of this bolt
It is that two kinds of parts tighten together, or a kind of part is fixed on some tool functional parts, have good
Prevent come off and fastening effect.The size of fluting cylindrical bolt is bigger, and the tightening torque being fastened is bigger.Therefore large-scale open
During the installation and removal of groove cylindrical bolt, if using simple instrument in addition to can not meeting required tightening torque, both taken
When again laborious, do not meet assembly technology requirement yet.The utility model proposes specific purpose tool, not only can laborsaving quickly to large-scale
Fluting cylindrical bolt is assembled, and ensures its fastening effect, can ensure that when being dismantled the periphery of fluting cylindrical bolt is not subject to
Damage.
Content of the invention
The purpose of this utility model is to provide a kind of instrument of fluting cylindrical bolt dismounting, for engine lubricating oil
The fluting cylindrical bolt of pressure maintaining valve is dismantled.
Below in conjunction with accompanying drawing, structural principle of the present utility model is illustrated.Fluting cylindrical bolt tool special for dismounting its
Structure is that the top surface of sleeve is provided with two semi-circular recesses, is provided with a straight rib, the inner side of sleeve is provided with one between two grooves
Individual foursquare cavity.
The instrument of fluting cylindrical bolt dismounting is supported the use with ratchet spanner, two semicircles of ratchet spanner and extracting tool
Connected in star matches, and the foursquare cavity of extracting tool is corresponding with the fluting cylindrical bolt of engine lubricating oil pressure maintaining valve.
Feature of the present utility model and beneficial effect be, solves larger fluting cylindrical bolt during engine assembly
It is impossible to ensure the problem of moment of torsion torque requirement during assembly or disassembly.Select different foursquare cavity dimension so that it may to difference
The fluting cylindrical bolt of specification carries out assembly or disassembly.And this specific purpose tool structure is simple, easy to use, it is easy to processing system
Make, there is good practical value.
Brief description
Fig. 1 is this utility model structural principle sketch.
Fig. 2 is the side view of Fig. 1.
Specific embodiment
Below in conjunction with accompanying drawing and by embodiment, structure of the present utility model is described further.
