Abstract
The invention provides a large part processing and leveling method. The method comprises the following steps: (1) roughly leveling and (2) finely leveling, wherein the step (1) of roughly leveling comprises the sub-steps: 1) firstly arranging three equal-height leveling blocks in a range of 180 degrees on a working table, then lifting and putting parts on the equal-height leveling blocks, and finally arranging a hydraulic jack in each equal-height leveling block position; and 2) roughly leveling the parts via rising and falling of the hydraulic jack by using a height caliper and simultaneously padding gaskets on the equal-height leveling blocks. The step (2) of finely leveling is characterized by communicating water with an alignment instrument. The method is simple and is convenient to operate; the measurement accuracy can be controlled within 0.02mm; the accuracy of the method is obviously higher than that of the conventional leveling method.

On high parallels, finally in one hydraulic jack of each equal-height padding iron location arrangements；
2) utilize height gauge, and by the lifting of hydraulic jack, part is carried out the most levelling, simultaneously at equal-height padding iron
Upper pad pad；
(2) essence is levelling: utilize water connection alignment instrument to carry out essence levelling.
As further technical scheme, thick levelling time, first levelling part left and right directions, more levelling fore-and-aft direction.
As further technical scheme, described water connection alignment instrument includes three identical water tumblers, two sections of flexible pipes and three
Individual contour survey mass, each water tumbler fixes a contour survey mass in same position transverse horizontal, at the bottom of one of them water tumbler
Portion arranges two waterpipe jointings, respectively arranges a waterpipe jointing bottom two other water tumbler, and described two sections of flexible pipes pass through water
Interface tube three water tumblers of connection.
As further technical scheme, utilize water connection alignment instrument carry out smart levelling time: 1) water is connected alignment instrument
Three water tumblers are arranged on the horizontal plane of part, and make the lower surface of contour survey mass and the horizontal plane laminating of part；
2) add water in water tumbler, and after the water surface is steady, at the same position of each contour survey mass, use micrometric depth gauge respectively
The contour survey mass of measurement, to the distance of the water surface, regulates hydraulic jack, so that each contour survey mass is to the water surface simultaneously
Distance equal, then pad pad on equal-height padding iron.
As further technical scheme, smart levelling time, first levelling part left and right directions, more levelling fore-and-aft direction.
As further technical scheme, the method further comprises the steps of: (3) and uses pressure plate mode, fills Clamp blocks,
Compress point with the strong point in a straight line.
As further technical scheme, after clamping parts, again measure contour survey mass extremely with micrometric depth gauge
The distance of the water surface, if change is not less than 0.05mm, then takes off water connection alignment instrument, and centering terminates, and otherwise unclamps part,
And change point is carried out pad, until levelling.
Compared with prior art, the inventive method is simple, easy to operate, and certainty of measurement can be controlled in 0.02mm with
In, more much higher than traditional leveling method precision.

Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
The inventive method in use, needs to use water connection alignment instrument, and the present invention provides a kind of water connection alignment instrument,
Its structure is as shown in Fig. 3～Fig. 7, and this alignment instrument is mainly contour by three identical 1, two sections of flexible pipes 2 of water tumbler and three
Survey mass 3 forms.The most each water tumbler fixes a contour survey mass 2 in same position transverse horizontal.Three water tumblers
In a water tumbler bottom two waterpipe jointings 4 are set, a waterpipe jointing is respectively set bottom two other water tumbler.Two
Section flexible pipe connects three water tumblers by waterpipe jointing.Water pipe head for be fixed on bottom water tumbler and with water tumbler inner space phase
Logical steel pipe.Contour survey mass 3 is rectangle survey mass, when it is fixed on water tumbler, and upper surface and water cup mouth plane
Equal.
In order to measure conveniently, water tumbler 1 is designed as including diapire and at least two sidewall, and one of them sidewall is planar side
Wall, contour survey mass is fixed in water tumbler flat sidewall be fixed in flat sidewall by packing ring and screw 5.This enforcement
Example provides a kind of concrete water tumbler structure, as shown in Figure 3, Figure 4, including diapire 11 and two sidewalls, one of them side
Wall is flat sidewall 12, and another sidewall is semicircular arc sidewall 13, also referred to as semi-circular cylindrical water tumbler.
The inventive method specifically includes step:
The most levelling:
1. first operative employee all lays three equal-height padding irons 6 on work top in the range of 180 degree, secondly by part 7
(as a example by nuclear power low pressure level Four dividing plate) handling is positioned on equal-height padding iron 6, finally in each equal-height padding iron 6 position
Arrange a hydraulic jack 8, see Fig. 1；
2. look for about straight part split.
3. use the special height gauge of scribing by bench worker, by the lifting of hydraulic jack 8, use and prop up on equal-height padding iron 6
Pad copper sheet or pad, make machined omoplate sealing surface the most levelling, and first levelling left and right directions in leveling procedures, before levelling
Rear to.
Essence is levelling:
1. water connect alignment instrument is uniform to be placed in part plane, and water tumbler (semi-circular cylindrical) spacing between any two is as far as possible
Greatly, in the case of ensureing that water tumbler 1 (semi-circular cylindrical) the planar side wall periphery 9 with part is close to, use and compress
Device 10 (this enforcement uses by the device holding out against screw and nut forms) makes baseplane and the nuclear power of contour survey mass 3
Dividing plate omoplate sealing surface fits tightly, and sees Fig. 2.
2. pouring in water connection alignment instrument, treats that the water surface is steady.
The most as shown in Figure 8, from the same position of the contour survey mass 3 of three water tumblers, use micrometric depth gauge inspection respectively
Survey the distance of contour survey mass 3 to the water surface, if A, B, C size measured is unequal, and hydraulic jack need to be passed through
Lifting, on equal-height padding iron, pad copper coin, copper sheet or pad adjust placement E, F, G tri-actual base of water tumbler respectively
The relative relief in 3, quasi-face, is gradually reduced the angle α in reference face and theoretical principle face so that it is the A of measurement, B,
C size relative size gradually reaches unanimity, until relative error is less than 0.03mm under free state.In leveling procedures first
Levelling left and right, in direction, the levelling world.
4. using pressure plate mode, fill Clamp blocks, compressing point otherwise to need to use auxiliary with the strong point in a straight line
Help supporting way.
5. it is again with micrometric depth gauge and detects the distance of contour survey mass 3 to the water surface, see if there is and changed, if becoming
Changing not less than 0.05mm, it is qualified to be considered as, and otherwise needs to unclamp workpiece pressuring clamping device, and change point is carried out pad, until full
Foot requirement.
6. from workpiece, take off water connection alignment instrument.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, it is noted that
All any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included in this
Within bright protection domain.
