Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail embodiment:
As shown in Figure 1, the utility model is a kind of engine cylinder cover air flue current stabilization test valve lift adjustment mechanism, comprise bolt 2, engine valve 6, engine cylinder cover 7, valve spring 8, described engine cylinder cover air flue current stabilization test valve lift adjustment mechanism also comprises dial gauge 1, dial gauge holder 3, frock clamp skewback 4, fixed support 5, described engine cylinder cover 7 is provided with bolt hole, and fixed support 5 is arranged on the engine cylinder cover 7, on the fixed support 5 bolt hole is set, bolt 2 passes frock clamp skewback 4, and head and engine valve 6 points fit, and described dial gauge 1 is fitted on the bolt top surface 11 of bolt 2 by dial gauge holder 3.
Bolt hole on the bolt hole of described engine cylinder cover 7 and the fixed support 5 all is set to incline structure, and the bolt hole on the bolt hole of engine cylinder cover 7 and the fixed support 5 is set to center line in the structure on the same line.
Described frock clamp skewback 4 is set to the structure of slope, and its slope angle equates with engine cylinder cover 7 bottom surface angles with engine valve 6 shafts; Described frock clamp skewback 4 is fastenedly connected with engine cylinder cover 7 by the fixed support 5 that is arranged on the side.
Bolt hole on the described frock clamp skewback 4 is set to the helicitic texture that cooperates with bolt 2.
Described engine valve 6 contacts with bolt 2, and is set to structure very close to each other.
The principle of work of the utility model engine cylinder cover air flue current stabilization test valve lift adjustment mechanism is as follows:
As shown in Figure 1: at first engine valve 6 and valve spring 8 all install.Boring on frock clamp skewback 4, and set out helicitic texture, its size matches with bolt 2; Frock clamp skewback 4 usefulness fixed supports 5 are installed on the engine cylinder cover 7, and guarantee that bolt 2 center lines and engine valve 6 center lines are on the same line; Measure the deflection (being the size of valve stroke) of bolt in the other end of bolt 2 with dial gauge 1, must eliminate the gap between bolt 2 and the engine valve 6 before measuring.
The utility model design proposal is the planform according to engine cylinder cover and valve group, be designed to the cover angle of inclination skewback the same with the angle of cylinder cap bottom surface with the valve shaft, come unseat the valve by screw thread with bolt, measure the other end of bolt again with dial gauge, be used for measuring the degree of depth of bolt unseat the valve, i.e. the size of valve stroke.
When adopting traditional valve lift adjustment mechanism to do the test of air flue current stabilization, its frock clamp need be done different frock clamps according to different engine cylinder cover types, frock clamp and engine cylinder cover are one to one, also will waste very large resource engine valve at the shaft tapping simultaneously.Adopt the design's valve lift adjustment mechanism can do the engine cylinder cover air flue current stabilization test of arbitrary money type, it is simple in structure, and is easy and simple to handle, quick, and it is more accurate to measure numerical value, satisfies testing requirements; The expense of also having saved workmanship clamping tool has greatly simultaneously been saved company cost.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
