In order to solve the problem that prior art exists, people have carried out long-term exploration, it is proposed that solution miscellaneous
Scheme.Such as, Chinese patent literature discloses the injection plunger set of a kind of engine cylinder-body, [application number:
201521008355.1], plunger bushing body is provided with axially through centre bore, the top of plunger bushing body is provided with flange
Mounting disc, flange mounting disc is provided with four bolt mounting holes the most uniform, and centre bore is divided into spray from top to bottom
Oil section, closing in section and plunger construction section, described plunger construction section, oil spout section, the diameter of closing in section are sequentially reduced；Plunger construction section
Sidewall on be provided with circumferential groove and lower circumferential groove, the axis of described upper circumferential groove offsets to the right relative to centre bore,
The axis of lower circumferential groove, relative to centre bore left shift, is provided with " 7 " font on the lower left side wall of plunger bushing body
Left oil leab, the right side wall of the bottom of plunger bushing body is provided with the right oil leab of " 7 " shape, left oil leab and lower ring
Communicating to groove, right oil leab communicates with upper circumferential groove.
Above-mentioned scheme improves the subproblem of prior art to a certain extent, but, the program the most at least exists
Following defect: structural strength is poor, service life is short.
Summary of the invention
The purpose of this utility model is for the problems referred to above, it is provided that the post for automobile engine that a kind of structural strength is high
Plug.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this is for the plunger bag of automobile engine
Including lug and cylinder, described lug is connected by flange with cylinder, and the end of described cylinder is provided with stigma, described stigma
In circular platform type and external diameter is along with reducing away from cylinder, described stigma is arc-shaped transition with the junction of cylinder, described post
Body and flange connections are arc-shaped transition, and on the end of described cylinder, edge is arc-shaped transition, described lug and Flange joint
Place is for arc-shaped transition, and described lug, flange, cylinder, stud axis is identical and be integral type structure, described lug and cylinder
External diameter identical, the width of described flange is the twice of lug external diameter, the cone angle of described stigma be less than 1 °.Design is more closed
Reason, precision is high；Each junction, all with arc-shaped transition, is reduced the loss of mechanical friction, cylinder and the interference fits of stigma, is improved
Structural strength, integral structure makes each parts be connected firmly；Simple in construction and easily fabricated.
In the above-mentioned plunger for automobile engine, described flange is opposed pairs ear body, described ear body
Outboard end be circular arc type and half that arc diameter size is cylinder external diameter.
In the above-mentioned plunger for automobile engine, described lug and the external diameter of cylinder are all 29mm.
In the above-mentioned plunger for automobile engine, a length of 19mm of described lug, the length of described cylinder
Degree is 26mm, a length of 17mm of described stigma.
