Abstract
The invention relates to a tool used for dismounting spare parts of a diesel engine, in particular to a spanner used for dismounting a high-pressure oil tube union nut of a diesel engine. The spanner comprises main structures of an operating handle (1), a guide slot structure (2), an axial positioning structure (3), an internal double offset ring spanner working surface (4) and the like, and is a slot structure that the opened internal regular dodecagon-shaped double offset ring spanner is combined with the axial positioning structure so as to increase the matching with the outer diameter of the high-pressure oil tube; and the high-efficient tool for dismounting the oil tube union nut is capable of quick insertion of an end part of the oil tube and accurate positioning and is capable of flexible operation in a narrow space. The spanner has the characteristics of being high in operating efficiency, humanized, high in reliability and the like, and has wide application prospect.
Description
Technical field
The present invention relates to a kind of the dismounting parts and components of diesel engine instrument that is applicable to, particularly a kind of spanner of dismounting diesel engine high-pressure fuel conduit union nut.
Background technology
In carrying out diesel fuel injection system correlation test process, operating personnel understand the high-pressure oil pipe assembly that is used for connecting high-pressure channel in the frequent disassembly system.And the union nut at high-pressure oil pipe two ends is for fixing oil pipe end, produces the critical component of high pressure sealing axial force, often applies when mounted the screw-down torque of (30 ~ 50) N.m different range according to vitta structure and sealing means.Simultaneously the Modern Engine layout design is more and more compacter, so that during the dismounting oil pipe, uses common open-end wrench and common inner hexagon spanner all to be difficult to dismantle, tends to cause the damage of union nut force part or destruction, and operating efficiency is extremely low.
Summary of the invention
The technical problem to be solved in the present invention is: the interior just polygon double offset ring spanner of opening is combined with axial location, increase notching construction, but provide a kind of quick insertion oil pipe end and axial location, the efficient oil pipe union nut extracting tool that can operate flexibly at small space, i.e. a kind of spanner for dismounting diesel engine high-pressure fuel conduit union nut.
Technical scheme accompanying drawings of the present invention is as follows:
A kind of spanner for dismounting diesel engine high-pressure fuel conduit union nut is comprised of the interior double offset ring spanner working face 4 of operating grip 1 and operating grip 1 one ends, and described interior double offset ring spanner working face 4 is dodecagon, cooperates, locates with the oil pipe union nut;
Described interior double offset ring spanner working face 4 is provided with guiding notching construction 2, and described guiding notching construction 2 groove widths cooperate with the oil pipe crest clearance;
The vertical plane of described interior double offset ring spanner working face 4 is provided with axial positioning structure 3, described axial positioning structure 3 and oil pipe union nut end contact and axial location.
Technique effect of the present invention is:
The efficient dismantling device of described a kind of dismounting high-pressure oil pipe used for diesel engine union nut has that simple in structure, easy to operate, accurate positioning is quick, a hommization, reliability high, no matter detects for automobile or maintenance all is with a wide range of applications.

The specific embodiment
Also the present invention will be further described in detail by reference to the accompanying drawings below by concrete embodiment.
The present invention relates to a kind of spanner for dismounting diesel engine high-pressure fuel conduit union nut, comprise operating grip 1, described operating grip 1 one ends are provided with interior double offset ring spanner working face 4, and described interior double offset ring spanner working face 4 is dodecagon, cooperates, locates with the oil pipe union nut; Described interior double offset ring spanner working face 4 is provided with guiding notching construction 2, and described guiding notching construction 2 groove widths cooperate with the oil pipe crest clearance; The vertical plane of described interior double offset ring spanner working face 4 is provided with axial positioning structure 3, described axial positioning structure 3 and oil pipe union nut end contact and axial location.
Patent of the present invention comprises the primary structures such as operating grip 1, guiding notching construction 2, axial positioning structure 3, interior double offset ring spanner working face 4.It is characterized in that interior double offset ring spanner working face adopts dodecagon, compare with common regular hexagon, more be conducive among a small circle, cooperate, locate with the high-pressure oil pipe union nut fast, realize quick, the accurately dismounting of oil pipe.Simultaneously spanner increase has notching construction 2, and groove width cooperates with the high-pressure oil pipe crest clearance, and the instrument of being convenient to is take the oil pipe outer surface as guiding, and quick insertion high-pressure oil pipe, and then accurate location have more hommization.Adopt simultaneously axial positioning structure 3, so that spanner is after inserting high-pressure oil pipe, fast and oil pipe union nut end contact and axial location, unusual slip can not occur, avoid causing that spanner comes off and personal injury.
The present invention can realize the quick location of high-pressure oil pipe used for diesel engine assembly union nut, efficient dismounting.
Consult shown in Figure 1, the efficient dismantling device of a kind of dismounting high-pressure oil pipe used for diesel engine union nut of patent of the present invention, profile is different from common open-end wrench and inner hexagon spanner, increases to be conducive to high-pressure oil pipe and to insert the notching construction 2 that plays guide effect; Consult among Fig. 4 shown in the B-B view, axial location structure 3 can produce positioning function with the oil pipe union nut, cooperates fast and easy, reliable dismounting nut with the dismounting active force working face 4 of dodecagon.
Consult among Fig. 3 shown in the A-A view, after the professional tool that relates to of patent of the present invention inserts high-pressure oil pipe smoothly, can utilize the rotation of dodecagon flexible structure, in tight space, find the fit angle suitable with the high-pressure oil pipe union nut, under the prerequisite that does not reduce transmission efficiency, realize efficient dismounting operation.
