It is convenient and efficient until angle is met the requirements.
Embodiment
Step 1. centering requirement；L1=L2, a1=a2=required angle a.
First jackshaft of step 2. and the second jackshaft have been placed on the base.
First centering indicator is mounted on the first jackshaft by step 3., and centering indicator schematic diagram is shown in Fig. 3.
3.1 are mounted on centering indicator flange base in the end flange of the first jackshaft, are tightened by bolts.
3.2 are packed into centering indicator pointer in the hole of centering indicator flange base, and the first centering indicator of adjustment refers to
Distance L of the needle end part to the flange base end of the first centering indicator3(see Fig. 2) records the scale reading of fixing bolt.
3.3 are fixed centering indicator pointer with fixing bolt (see Fig. 3).
Second centering indicator is mounted on the second jackshaft by step 4. by the method for step 3.
Step 5. adjusts the position of the first jackshaft and the second jackshaft, indicates the first centering indicator and the second centering
The end of device contacts.
Step 6. measures the distance (left and right directions) of the first centering indicator and centering indicator, sees Fig. 4.
Step 7. adjusts the first jackshaft and the second jackshaft, makes l1=l2。
Step 8. rotates the first jackshaft, and whether the end of the first centering indicator of observation, which has, is deviateed the second centering indicator
End, if without indicating qualified.
Step 9. rotates the second jackshaft, and whether the end of the second centering indicator of observation, which has, is deviateed the first centering indicator
End, if without indicating qualified.
Step 10. measures the distance L (measurement of the first centering indicator and the second centering indicator between identical graduation point
Position is at the top of the pointer to middle indicator), see Fig. 5.
Step 11. calculates angle a corresponding to distance L1(a2), the table of comparisons of distance L and angle a are shown in Table 1.
Wherein, L1It is the instruction of the total length of the first centering indicator, i.e. the first intermediate shaft flange front end face and the first centering
The distance of device end (circle point)；L2It is the total length of the second centering indicator, i.e. the second intermediate shaft flange front end face and second pair
The distance of middle indicator end (circle point)；L3It is flange base of the first centering indicator pointer end to the first centering indicator
The distance of end；L4It is distance of the second centering indicator pointer end to the flange base end of the first centering indicator；a1It is
The center line of first jackshaft (the first centering indicator) and the angle of the first jackshaft and two flange center's lines；a2It is second
The center line of jackshaft (the second centering indicator) and the angle of the first jackshaft and two flange center's lines；
Fig. 4 is the visual angle (vertically looking down from upper) of top view, that is to say the projection of centering indicator in the horizontal plane；l1
And l2It is the vertical range in projection between the flange of the first centering indicator and the flange of the second centering indicator, l1=l2I.e.
Indicate that two flanges are parallel in projection.
Relationship in corresponding table: distance L see also illustrates；Under normal circumstances, distance is the data for being easier to measure, and angle
It is more difficult directly to be measured with tool, but corresponding angle is calculated according to the relationship of trigonometric function after measuring distance；In order to save
Calculating repeatedly in the construction process, specially calculation before construction got well a certain angle a positive and negative section (such as: (a-3) °
To distance value L corresponding to (a+3) °)；In the construction process, the L value in the table of comparisons is compared with the data L of actual measurement, from
And it can rapidly obtain an angle about.
Illustrate: the table of comparisons sets centering indicator in a certain fixed calibration points such as (scale S=100+75)
Table 1
Calculation formula: L=2*S*cos (a/2).
Explanation about S in formula: S is the distance that centering indicator end (pointer needle point) arrives a certain scale；Because of scale
Zero point not instead of pointer needle point, 100 in an optional distance such as file be exactly distance of the needle point to scale zero
It is that 100, S=100+75 indicates to be distance of the needle point at scale 75.
12. measuring L, corresponding table 1 obtains respective angles, sees whether meet the requirements；If being unsatisfactory for requiring, in adjustment first
Between axis and the second jackshaft, until the corresponding angle of the L measured is met the requirements.
In conclusion the beneficial effect of the method for determining intermediate shaft assignment angle provided by the invention is: among two
After axis and two centering indicators install, adjusts position and measure distance, after being calculated according to formula L=2*S*cos (a/2)
Intermediate shaft assignment angle a corresponding to distance L is obtained, if a is undesirable, continues to adjust among the first jackshaft and second
Axis, it is convenient and efficient until the corresponding angle of the L measured is met the requirements.
