The sinusoidal centering frame has wide application scope, the measuring method is simple, the hole measurement can be carried out, and the shaft measurement can be also carried out, and the problem of coaxiality detection of large-size hole or shaft can be solved, and the product quality can be enhanced.

Description

A kind of sine centering frame that detects coaxiality of large diameter cylindrical surface
Technical field
The utility model relates to a kind of axiality detection device, especially a kind of sine centering frame that detects coaxiality of large diameter cylindrical surface.
Background technology
At present, right alignment generally is divided into the right alignment in hole and the right alignment of axle, for the right alignment in the hole of large scale engineering goods, detects, and in practice, be all to adopt optical means, use tripod centering frame to determine the Kong center, read the deviation of center, hole relative datum axis with micr-alignment telescope.But tripod centering frame can only be for diameter the location in the hole within 228mm, the right alignment that is greater than the large scale engineering goods such as the hole of 528mm or axle for diameter detects, and there is no at present accurately, measurement mechanism reliably.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model purpose is to provide a kind of sine centering frame that detects coaxiality of large diameter cylindrical surface, this device can overcome the limitation that existing tripod centering frame detects, be applicable to detecting the center positioning method of large diameter hole and axle, efficiently solve the right alignment that diameter reaches the hole of 700mm and axle and detect a difficult problem, guarantee that right alignment detects accurate, reliable, easy to operate, positioning precision is high.
In order to realize the foregoing invention purpose, the utility model adopts technical scheme as described below:
A kind of sine centering frame that detects coaxiality of large diameter cylindrical surface, comprise measurement bay, combined diagram level and measuring stick, measurement bay is comprised of base and the mark post be arranged on base, the left and right sides of base lower surface is symmetrically arranged with respectively measuring stick, the top of mark post is provided with the installation targets hole, be placed with combined diagram level on the upper surface of base, the center line of described installation targets hole and measuring stick is parallel to each other.
Further, described measuring stick is fixed by screws on measurement bay.
Owing to adopting technique scheme, the utlity model has following superiority:
The sine centering frame of the detection coaxiality of large diameter cylindrical surface that the utility model provides, applied widely, measuring method is simple, swift and convenient to operate, increases work efficiency; Can not only carry out the measurement in hole, can also carry out the measurement of axle, and all can use for hole and the axle of different-diameter, full and accurate, accurate, reliable, the effective right alignment that has solved oversized hole or axle of the structure of measurement detects a difficult problem, thereby has improved the quality of product; The saving of labor, save time, be convenient to promote.

In figure; The 1-measurement bay; The 2-combined diagram level; The 3-measuring stick; The 4-mark post; 5-installation targets hole; The 6-micr-alignment telescope; The 7-mill trunnion; The 8-optical axis .
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
In conjunction with Fig. 1, a kind of sine centering frame that detects coaxiality of large diameter cylindrical surface, comprise measurement bay 1, combined diagram level 2 and measuring stick 3, measurement bay 1 is comprised of base and the mark post 4 be arranged on base, the left and right sides of base lower surface is symmetrically arranged with respectively measuring stick 3, and measuring stick 3 is fixed by screws on measurement bay 1; The top of mark post 4 is provided with installation targets hole 5, is placed with combined diagram level 2 on the upper surface of base, and the center line of described installation targets hole 5 and measuring stick 3 is parallel to each other.
Concrete using method of the present utility model is as follows:
As shown in Figure 3, the frame A that first sine felt relieved is placed on respectively on the inner headed face at mill trunnion 7 two ends, left and right with sinusoidal centering frame B, and the sine frame A that feels relieved is placed in to A1 place, and the sinusoidal frame B that feels relieved is placed in the B1 place; With their positions in a circumferential direction of skin hammer fine setting, make combined diagram level 2 on sinusoidal centering frame A and sinusoidal centering frame B all in zero-bit; Adjust micr-alignment telescope 6 on 4 degree of freedom, make its optical axis 8 by sine the feel relieved center in installation targets hole 5 of frame B of frame A and sine of feel relieved; At this moment, the optical axis 8 of micr-alignment telescope 6 is exactly datum axis;
Again sine centering frame A and sinusoidal centering frame B are moved to respectively to B2 place, A2Yu position, position, make its combined diagram level 2 again all in zero-bit, aim at the installation targets Kong center of sinusoidal centering frame A and sinusoidal centering frame B by micr-alignment telescope 6, read their relative optical axis 8 deviation X in the horizontal and vertical directions a, Y aand X b, Y b; Finally, determine level and offset of vertical amount X, the Y of maximum deviation point according to minimal condition, detect the coaxiality error in the hole of mill trunnion: f=(X 2+ Y 2) 1 /2 .
Sinusoidal centering frame is one section arc location by the face of cylinder, in order to eliminate the deviation from circular from measured axis or hole, way by rotational workpieces, the circular arc of getting four symmetric positions on the whole face of cylinder is detected, detected four coaxiality errors, using in four coaxiality errors a maximum result as final coaxiality error.
