Embodiment
Embodiments of the present invention are further illustrated with reference to specific embodiment：
See Fig. 1-Fig. 8, a kind of motor Fast Installation spotting device, including following method and step：
1) on the basis of mechanical axis 1, with dial gauge or amesdial measure mechanically and electrically machine shaft coupling it is radial and axial partially
Difference, two axles will rotate simultaneously during measurement, with the influence of abatement apparatus foozle；And by whether (upper and lower 2 points of " returning circle "
Sum is equal to 2 sums in left and right) examine the accuracy of measurement.
2) radial direction is detected and recorded with axial deviation numerical value up and down and in the both direction of left and right, utilize formulaWithAdjustment displacement and the adjustment position of left and right directions of the above-below direction of motor shaft 2 are calculated respectively
Move, wherein：For the adjustment displacement of motor front foot,For the adjustment displacement of the motor rear foot.
In formula：B is radial missing；
A is axial deviation；
D is the diameter that end face is beaten at table；
Y is distance of the motor front foot to shaft coupling；
X is distance of the motor rear foot to motor front foot；
When two shaft coupling inclination angle opening upwards, in formulaTake on the occasion of calculating；When two shaft coupling inclination angles, Open Side Down
When, in formulaNegative value is taken to calculate；When electrical axis are higher than mechanical axis, b takes negative value to calculate in formula；Work as electrical axis
During less than mechanical axis, b is taken on the occasion of calculating in formula；
3) according to the numerical value calculated in step 2), using the pad of the numerical value thickness respectively to above and below motor progress and left and right
The adjustment of displacement in direction, make motor shaft 1 and mechanical axis 2 coaxial.
Either above-below direction or left and right directions, all it is likely to occur eight kinds of eccentric situations as Figure 1-Figure 8.In figure
A is radial missing, and b is axial deviation.Upper in figure be positive direction, time is negative direction, that is to say, that when calculate must be worth on the occasion of
When, according to view direction, adjust upward displacement；When calculate must be worth for it is negative when, according to view direction, adjust displacement downwards.
Embodiment 1：
See the top view that Fig. 9 is motor, A in figure (under) for a left side, B (on) for the right side.It can be seen that in left and right directions
On, deviation be present in the radial direction and axial direction of motor shaft 2 and mechanical axis 1.Motor shaft 2 is first measured using the above method relative to machine
The radial missing b=0.14mm and axial deviation a=0.08mm of tool axle 1.Diameter D=240mm at table is beaten in end face, and motor front foot is arrived
The distance y=200mm of shaft coupling, the distance x=2300mm of the motor rear foot to motor front foot.See Fig. 9, two shaft coupling inclination angle openings
Upwards, thereforeTake on the occasion of calculating；Electrical axis are less than mechanical axis, therefore b takes and is on the occasion of calculating, calculation formula：
Wherein 0.21mm is the adjustment displacement of motor front foot, and 0.97mm is the adjustment displacement of the motor rear foot.Due to calculated value
For on the occasion of therefore motor 4 should being adjusted upward in view direction, actual direction should adjust motor 4 to the right.What is adjusted is specific
Method is as follows：
Pin 3,5 jackscrews before and after motor right side are unclamped, it is 0.21mm that front foot 3 fills in thickness with jackscrew end on the right side of motor
Clearance gauge, the rear foot 5 fills in the clearance gauge that thickness is 0.97mm with jackscrew end on the right side of motor, two jackscrews is tightened, in two jackscrew caps
It is upper to draw mark respectively, two jackscrews are unclamped, extract clearance gauge, unclamp motor base bolt, add the pad of adjusting height, then
Two jackscrews screw back original position by mark on the right side of motor.Tighten jackscrew on the left of motor, you can move motor and clearance gauge thickness to the right
Consistent distance, end clearance are stayed according to technical standard, finally tighten motor foot bolt, beat table measurement centering result.
Embodiment 2：
See the top view that Figure 10 is motor 4, A in figure (under) for a left side, B (on) for the right side.It can be seen that in right and left
Upwards, there is deviation in the radial direction and axial direction of motor shaft 2 and mechanical axis 1.First measured using the above method motor shaft 2 relative to
The radial missing b=0.2mm and axial deviation a=0.1mm of mechanical axis 1.Diameter D=240mm at table is beaten in end face, and motor front foot is arrived
The distance y=200mm of shaft coupling, the distance x=2300mm of the motor rear foot to motor front foot.See Figure 10, two shaft coupling inclination angles are opened
Mouth is downward, thereforeNegative value is taken to calculate；Electrical axis are higher than mechanical axis, therefore b takes negative value to calculate, and calculation formula is：
Wherein 0.28mm is the adjustment displacement of motor front foot, and 1.24mm is the adjustment displacement of the motor rear foot.Due to calculated value
For negative value, therefore motor should be adjusted downwards in view direction, actual direction should adjust motor to the left.The specific side of adjustment
Method is as follows：
Pin 6,7 jackscrews before and after motor left side are unclamped, it is 0.28mm that front foot 6 fills in thickness with jackscrew end on the left of motor
Clearance gauge, the rear foot 7 fills in the clearance gauge that thickness is 1.24mm with jackscrew end on the left of motor, two jackscrews is tightened, in two jackscrew caps
It is upper to draw mark respectively, two jackscrews are unclamped, extract clearance gauge, unclamp motor base bolt, add the pad of adjustment height, then
Two jackscrews on the left of motor are screwed back original position by mark.Tighten jackscrew on the right side of motor, you can motor is mobile to the left thick with clearance gauge
Consistent distance is spent, end clearance is stayed according to technical standard, finally tightens motor foot bolt, beats table measurement centering knot
Fruit.
The adjustment of motor upper-lower position, due to actual direction and direction as shown be it is consistent, therefore result of calculation on the occasion of when,
Increase foundation bolt pad, adjust upward displacement motor.If result of calculation obtains negative value, foundation bolt pad is reduced, to downward
Whole displacement motor.
The present invention is applicable not only to the installation centering of motor, and can be generalized to similar mechanical equipment installation and (have coaxial
Spend desired equipment), there is universal directive significance to mechanical equipment installation engineering.
