Embodiment
Come the centering measurement mechanism of flange mounting hole before and after the expansion pipe of the utility model marine diesel is described in further detail below in conjunction with accompanying drawing and specific embodiment, but can not limit protection domain of the present utility model with this.
The centering measurement mechanism of flange mounting hole mainly is that flange is installed the problem that misplaces before and after solving expansion pipe before and after the expansion pipe of the utility model marine diesel, purpose is the side-play amount of flange before and after the expansion pipe will be adjusted to the right place, satisfies the adjustment requirement of low-speed diesel engine expansion pipe.
The primary structure of centering measurement mechanism of the present utility model as shown in Figure 1, Fig. 1 is the structural representation of the centering measurement mechanism of flange mounting hole before and after the expansion pipe of the utility model marine diesel.As seen from the figure, the centering measurement mechanism of flange mounting hole is made up of pedestal 1, gauge rod 2 and movable gage 3 before and after the marine diesel expansion pipe.
Have the inside groove of a strip on pedestal 1, the length of this inside groove is greater than the distance of marine diesel expansion pipe upper flange relative opening.Its objective is the needs of the flange centering measurement that adapts to different model, make the flange relative opening of different distance all can be fixed in the above-mentioned inside groove.For easy to use, reduce manufacturing cost, pedestal 1 is designed to square shaft-like, and its inside groove is positioned at shaft-like middle part.
An end of inside groove vertically is provided with described gauge rod 2 on pedestal 1, this gauge rod 2 is for having the square bar of scale, the bottom of gauge rod 2 is fixed in the described inside groove movably, removable being meant here can be moved with keeping its verticality in inside groove, mainly is the needs of flange when measuring that satisfy different-diameter.Require vertically between gauge rod 2 and the pedestal 1, and gauge rod 2 is the linear bar of standard.
The long limit of oblong aperture is provided with scale on the described movable gage 3, and the scale zero on the movable gage 3 is positioned at the middle part, increases successively to both sides, and gauge rod 2 top middle portion are provided with the standard lines that is used to identify.The distance that can come the comparison hole to depart from the standard tag line on the gauge rod 2 is convenient to operation and correction like this.
By the said structure setting, centering measurement mechanism of the present utility model just can carry out centering have been measured the front and back flange of expansion pipe, and can be general between the expansion pipe of different model.
The concrete application of centering measurement mechanism of the present utility model as shown in Figure 2, Fig. 2 is a centering measurement mechanism of the present utility model at the synoptic diagram that flange mounting hole before and after the marine diesel expansion pipe is measured.As seen from the figure, in centering measurement mechanism of the present utility model use, specifically can comprise the steps:
At first, marine diesel expansion pipe 4 and two flanges are ready to complete, then one of them flange are weldingly fixed on an end of expansion pipe.
Secondly, an end of welding being finished flange is shelved on the pedestal 1 of centering measurement mechanism, because this flange contact bottom surface, can be called rear flange 6, two relative on the rear flange 6 mounting holes are aligned in inside groove on the benchmark 1, pass these two relative mounting holes with two screws expansion pipe 4 and rear flange 6 are fixed with the centering measurement mechanism.
Once more, with another flange as forward flange 5, forward flange 5 is positioned over the top of expansion pipe 4, carry out with rear flange 6 on mounting hole tentatively align, then the movable gage 3 on the centering measurement mechanism is being moved on the gauge rod 2 on the forward flange 5, at first check on the forward flange 5 with rear flange 6 on corresponding mounting hole whether align, the standard of checking is to see that mounting hole on the forward flange 5 is whether corresponding to the standard lines at gauge rod 2 tops, if not lining up and then measuring its difference amount with movable gage 3 is what, adjust alignment then, then can prepare after the alignment forward flange 5 is fixed in the expansion pipe 4.
Once more, remove above-mentioned centering measurement mechanism, forward flange 5 is weldingly fixed in the expansion pipe 4.
At last, above-mentioned centering measurement mechanism is installed to once more on the rear flange 6 or forward flange 5 of expansion pipe 4, whether the mounting hole of flange correspondence has dislocation before and after detecting, and measures its degree of misalignment with the scale on the movable gage 3 and whether satisfies the error range that technical standard allows if having dislocation.
This instrument can carry out the trickle adjustment of expansion pipe front and back flange mounting hole relative position, get final product the variable quantity of observed data in the adjustment process, and only need 1 operator of tool operation, and improved adjustment precision and work efficiency, be applicable to diesel engine and main equipment installation expansion pipe.
Undoubtedly, the centering measurement mechanism of flange mounting hole can also have other structure to replace form, version that is not limited only to mention in the foregoing description and using method before and after the marine diesel expansion pipe of the present utility model.Generally speaking, protection domain of the present utility model also comprises other conspicuous for those skilled in the art conversion and substitutes.
