Abstract
Engine and carburetor negative pressure adjustment system, including frame, computer are the utility model is related to, the frame is provided with stepper motor, orientation tapered sleeve, straight screwdriver and Phillips screwdriver；The straight screwdriver is used for the word screw for adjusting SJ negative pressure, and the Phillips screwdriver is used for the Philip's head screw for adjusting MJ negative pressure, orientation tapered sleeve is respectively arranged with straight screwdriver and Phillips screwdriver, and by orienting tapered sleeve fixed in the frame；The stepper motor is provided with two and is controlled by computer, and drives straight screwdriver and Phillips screwdriver rotation respectively.The utility model uses orientation tapered sleeve to influence degree of regulation to avoid occurring rocking during screw is adjusted using duplexing structure design, the synchronous adjust automatically MJ negative pressure adjustments screw of energy and SJ negative pressure adjustment screws.
Description
Technical field
It the utility model is related to idling owner negative pressure adjustment technology when engine and carburetor dispatches from the factory.
Background technology
Engine and carburetor is before dispatching from the factory, it is necessary to manually make MJ negative pressure and SJ negative pressure adjustments to certain suitable position
MJ negative pressure values and SJ negative pressure values meet idling and dispatched from the factory regulation.Past, usually by the MJ negative pressure on manual adjustment carburetor
Adjusting screw and SJ negative pressure adjustment screws, to adjust above-mentioned negative pressure parameter.
Because the change of MJ negative pressure values influences whether the change of SJ negative pressure values, only above-mentioned two adjusting screw cooperates
The value for meeting specification can be just adjusted to, this, which gives to manually adjust, brings very big difficulty, because manually can only once adjust one
Screw, it is difficult to which the degree that two screws are adjusted to cooperate, so the precision of manual adjustment is very low, misses by a mile.
The content of the invention
To solve the technical problem present in prior art, the utility model provides engine and carburetor negative pressure adjustment system
System, the system are adopted using duplexing structure design, the synchronous adjust automatically MJ negative pressure adjustments screw of energy and SJ negative pressure adjustment screws
With orientation tapered sleeve degree of regulation is influenceed to avoid occurring rocking during screw is adjusted.
The utility model is realized using following technical scheme：Engine and carburetor negative pressure adjustment system, including frame, meter
Calculation machine, the frame are provided with stepper motor, orientation tapered sleeve, straight screwdriver and Phillips screwdriver；The straight screwdriver is used
In a word screw of adjustment SJ negative pressure, the Phillips screwdriver is used for the Philip's head screw for adjusting MJ negative pressure, straight screwdriver and ten
Orientation tapered sleeve is respectively arranged with word screwdriver, and by orienting tapered sleeve fixed in the frame；The stepper motor is provided with
Two and computer is controlled by, and drives straight screwdriver and Phillips screwdriver rotation respectively.
The utility model compared with prior art, has the following advantages that and beneficial effect：
1st, duplexing structure design：Straight screwdriver and Phillips screwdriver are driven respectively with two stepper motors, to realize
Synchronous adjustment MJ negative pressure adjustments screw and SJ negative pressure adjustment screws, alignment error is small, and precision is high.
2nd, because straight screwdriver and Phillips screwdriver are long, MJ the and SJ negative pressure adjustment screws on adjustment carburetor
During easily rock, screwdriver can be ensured behind the center of alignment screw using tapered sleeve is oriented, in the process entirely adjusted
In no longer deviate.
3rd, easily there is skidding during being adjusted due to straight screwdriver, thus the utility model is in a word screw
Guide sleeve is additionally arranged on knife, when straight screwdriver contacts with carburetor screw, straight screwdriver can be prevented by the guide sleeve
Skid when rotated and deviate the flat recess mouth of screw.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1：Orient tapered sleeve；2：Stepper motor；3：Straight screwdriver guide sleeve；4 straight screwdrivers；5：Philip's head screw
Knife；6：Propulsion cylinder.
Embodiment
The utility model is described in further detail with reference to embodiment and accompanying drawing, but implementation of the present utility model
Mode not limited to this.
Embodiment
As shown in figure 1, the utility model includes using double automatic mechanism, frame, computer (figure are specifically included
Not shown in), frame is provided with propulsion cylinder 6, stepper motor 2, orients tapered sleeve 1, straight screwdriver 4 and Phillips screwdriver 5, and one
The periphery of word screwdriver 4 is also nested with guide sleeve 3, and stepper motor 2 is provided with two, and orientation tapered sleeve 1 also is provided with two, propulsion cylinder
6 propulsion for adjusting whole engine and carburetor negative pressure adjustment system.
Straight screwdriver 4 is used for the word screw for adjusting SJ negative pressure, and Phillips screwdriver 5 is used for the cross spiral shell for adjusting MJ negative pressure
Silk.Orientation tapered sleeve 1 is respectively equipped with straight screwdriver 4 and Phillips screwdriver 5, and is fixed to by orienting tapered sleeve 1 in frame, two
Platform stepper motor 2 is controlled by computer and drives straight screwdriver 4 and Phillips screwdriver 5 to rotate respectively.Orient the main of tapered sleeve
Effect is to prevent from swinging because screw is oversize, simultaneously as being two screwdrivers and together, using tapered sleeve form, can be saved
Save space.
Wherein, straight screwdriver 4 and Phillips screwdriver 5 are the electric screw driver of designed, designed, and two screwdrivers are simultaneously
MJ negative pressure adjustments screw and SJ negative pressure adjustment screws are adjusted.The amplitude of adjustment and control, it is electric to stepping dependent on calculating
The instruction that machine is sent.
Orientation tapered sleeve 1 mainly prevents straight screwdriver 4 or Phillips screwdriver 5 from being put after being aligned with carburetor benchmark
It is dynamic.
When straight screwdriver contacts with carburetor screw, by straight screwdriver guide sleeve 3, straight screwdriver can be prevented
Skid when rotated, so as to deviate the flat recess mouth of screw.
Above-described embodiment is the preferable embodiment of the utility model, but embodiment of the present utility model is not by above-mentioned
The limitation of embodiment, it is other it is any without departing from Spirit Essence of the present utility model with made under principle change, modify, replace
Generation, combination, simplify, should be equivalent substitute mode, be included within the scope of protection of the utility model.
