Section precision is not only directly related to the reliability of test result, but also influences engine performance and detection machine service life.
Laser alignment instrument be it is a kind of can effectively detect engine crankshaft flywheel end and detection machine main shaft whether the equipment of centering,
Its is easy to operate, but expensive, is a no small burden for medium-sized and small enterprises.
Summary of the invention
At low cost start machine testing centering adjustment equipment the purpose of the present invention is to provide a kind of.
In order to achieve the above objectives, the present invention adopts the following technical scheme:
Start machine testing centering adjustment equipment, including the testing agency being arranged on rack and regulating mechanism, the tune
Section mechanism includes the vertical displacement part of the transverse shift part for driving engine transverse movement and vertical motion；The detection machine
Structure includes fixed disk and sleeve, and circuit orbit, the center of circle of the circuit orbit and detection machine main shaft are offered in the fixed disk
Axis be overlapped, the sleeve is open at one end, and telescoping rod, the telescoping rod are hinged at the center of the sleeve other end
Including rotating bar and cavity, the cavity is fastened in circuit orbit, and sliding block, first switch and the second switch are equipped in cavity,
Sliding block is slidably connected at intracavitary, and first switch and the second switch is located at sliding block two sides, and first switch and the second switch is sliding
In the cavity, first switch and the second switch is equipped with the first inclined-plane for dynamic setting, and sliding block is equipped with the cooperated with the first inclined-plane
Two inclined-planes open up on cavity wall there are two the through-hole passed through respectively for first switch and the second switch, and first switch and the
Two switches are connected with elastic component between cavity inner wall respectively, and first switch is positive for controlling transverse shift part and vertical displacement part
Movement, for controlling transverse shift part and vertical displacement part counter motion, sliding block is fixedly connected first switch with rotating bar, round
Track inner sidewall is equipped with the first conductive sheet and the second conductive sheet, and the first conductive sheet is electrically connected with transverse shift part, and second is conductive
Piece is electrically connected with vertical displacement part.
The working principle of this programme is:
Testing agency is for detecting whether crankshaft-flywheel end is aligned with detection machine main shaft, and regulating mechanism is for automatically adjusting hair
Position of the motivation on rack, to guarantee crankshaft and the centering of detection machine main shaft.
In testing agency, due to position of the detection machine on rack be it is fixed, be fixed on detection machine main shaft
Fixed disk can be used as detection crankshaft and detection machine main shaft whether the object of reference of centering, circle is done in telescoping rod one end in circuit orbit
When Zhou Yundong, if rotating bar is overlapped with the axis at sleeve connection just with crankshaft, telescoping rod length in rotation is kept not
Become, the motion profile of telescoping rod surrounds a circular cone just, if rotating bar is not weighed at sleeve connection with the axis of crankshaft
It closes, shows that detection machine main-shaft axis is not overlapped with crankshaft center line, need to adjust engine location so that the two centering, when crankshaft exists
When eccentric in transverse direction, when telescoping rod moves in a circle in circuit orbit, the state in compression or elongation always, when stretching
Contracting rod piece is when in a compressed state, and the intracorporal sliding block of chamber is moved towards the direction close to first switch, the second inclined-plane on sliding block
The first inclined-plane in first switch is squeezed, moves first switch towards the direction close to the first conductive sheet, first switch and the
The contact of one conductive sheet, first switch are connected to by the first conductive sheet with transverse shift part, and first switch is controlling transverse shift part just
To movement, so that engine be driven horizontally to move towards the center point close to circuit orbit.When crankshaft is vertically eccentric
When, with laterally it is upper eccentric similarly, when telescoping rod moves in a circle in circuit orbit, also always in compression or elongation
State, when telescoping rod is when in a compressed state, first switch is connected to by the second conductive sheet with vertical displacement part, first switch
Transverse shift part forward motion is controlled, so that engine is driven horizontally to move towards the center point close to circuit orbit, when
When telescoping rod is in elongation state, second switch is connected to by the second conductive sheet with vertical displacement part, and second switch control is horizontal
To displacement member counter motion, so that engine be driven horizontally to move towards the center point close to circuit orbit.
Following technical effect can be reached using this programme:
1, without gage measuring, error caused by avoiding because of manual measurement, and hand-motion need to be only used when operation
Rotating bar one end moves in a circle in circuit orbit, easy to operate, and this programme structure is simple, and all parts are normal
See components, it is cheap, it is particularly suitable for medium-sized and small enterprises for starting machine testing；
2, position of the engine on rack is automatically adjusted by regulating mechanism, examines the axis of engine crankshaft from trend
Survey machine main-shaft axis is drawn close, until the two is overlapped the centering for realizing engine and detection machine；
3, it by the cooperation of cavity and rotating bar, realizes and judges automatically whether eccentric and bias the side of engine crankshaft
To.
Further, the angle that the center of circle of the first conductive sheet and the second conductive sheet and circuit orbit is formed is 60 degree.At this time
The distance between one conductive sheet and the second conductive sheet are unlikely to too close, therefore the work of transverse shift part and vertical displacement part is mutually not
It influences.
