Abstract
The invention discloses a static roundness measurement device and method. The static roundness measurement device is composed of a base with parallel bottom angles, a dial indicator and a dial indicator locking bolt. The method includes the steps of firstly, manufacturing the base; secondly, assembling the device; thirdly, selecting a datum cambered surface; fourthly, measuring data. In the fourth step, the measuring device is moved in the circumferential direction so that a pointer of the dial indicator can slide on the measured outer round surface, the change of the degree of the dial indicator is read, and finally the roundness value is obtained. The measuring device can independently measure the size of a workpiece without being matched with other devices, and therefore the larger the size of the workpiece is, the better the measurement cost is embodied; a measurer does not need to grasp the lying operation technology or the workpiece clamping and correcting technology; the clamping and aligning accuracy of the workpiece on the device is ensured due to the measurement result, limitation on diameter indirect measurement is eliminated, and measurement accuracy is improved.
Description
Technical field:
The present invention relates to measure under a kind of static state the circularity of rotary work piece or assembling rotary work piece and measurement mechanism and the method that relative radius changes.
Background technology:
The cylindrical of turbogenerator shaft retaining ring seam and termination slot wedge retaining ring seam, traditional handicraft adopts termination slot wedge is assembled in rotating shaft, with car retaining ring seam.This technique can ensure rotating shaft retaining ring seam and termination slot wedge retaining ring seam cambered surface radius measure-alike, circularity form and position tolerance is accurate.Nuclear power Half Speed turbogenerator shaft retaining ring seam is processed separately, after processing inserting slot, and prepackage termination slot wedge the retaining ring seam cambered surface with addition of work termination slot wedge.With addition of work and assemble after the slot wedge of termination, retaining ring seam coordinates the circularity form and position tolerance of cambered surface, there is no feasible measuring method under static state, installs because termination slot wedge is symmetrical, measure the method for diameter by outside micrometer, cannot accurately judge symmetrical two place's measuring point radius error trend.Relatively feasible measuring method is: use large-scale sleeping carriage to make workpiece under rotation status, use the external disc of clock gauge to measure, obtain relative outside dimension and circularity.Based on above-mentioned background, be badly in need of a kind of brand-new measuring method of research and development, coordinate the circularity form and position tolerance of cambered surface and outside dimension relatively to check with addition of the termination slot wedge seam after work.
Summary of the invention:
The object of this invention is to provide rotary work piece or the circularity form and position tolerance of assembling rotary work piece and the measuring method of relative radius under a kind of safer, more convenient, static state that versatility is stronger.Nuclear power Half Speed rotating shaft seam roundness measurement after the assembling termination slot wedge that is applicable to mention in technical background, measures circularity and relative radius for a greater variety of assembling rotary work pieces and changes a kind of simple, accurate and effective measurement means is provided.
Technical scheme of the present invention is: this measurement mechanism is made up of the base with parallel base angle (2) (1), clock gauge (3) and clock gauge clamping screw (4), and its measuring method comprises the steps:
1) base is made: first according to measured workpiece benchmark cambered surface length, manufacture and design the base (1) of measurement mechanism, cylindrical base angle, base both sides (2) is parallel, as the guide rail of measurement mechanism, there is the clock gauge positioning through hole that connects base base top, and there is locking screw pit pilot hole side;
2) device assembling: clock gauge (3) is penetrated to the pilot hole of base, and lock the position of clock gauge on base by the clamping screw of side;
3) choose benchmark cambered surface: survey instrument base closed slide is placed in benchmark cambered surface, the closed slide at base base angle and measured workpiece form two parallel line contacts, clock gauge indicator frame is at benchmark cambered surface cylindrical place and the number of degrees are made zero, and sets up measuring basis;
4) measurement data: measurement mechanism is moved in tested cambered surface, and measurement mechanism base angle is supported on measuring point both sides, and clock gauge pointer is supported on concrete measuring point, reads the clock gauge number of degrees, obtains relative radius;
5) traverse measuring device along the circumferential direction slides clock gauge pointer on tested periphery, reads the clock gauge number of degrees and changes, and obtains circularities.
Technique effect:
Traditional handicraft, the circularity behavior tolerance measurement of rotary work piece need carry out complex operation and dependence equipment on clamping scope is greater than the sleeping carriage of workpiece size.During due to clamping workpiece centering, exist certain error, measurement result cannot get rid of this part of error amount.Conventional gauges can only be measured the diameter dimension of rotary work piece in addition, and for assembling rotary work piece, the relative radius of assembling parts can only be measured indirectly according to diameter dimension, and radius error judges inaccurate.
The present invention's tool compared with traditional process has the following advantages:
1, instrument is with low cost, measures with low cost;
2, measuring method is simply easy to grasp, simple operation;
3, measurement result is accurate.
In application process of the present invention, do not need equipment to coordinate completely, can measure by complete independently workpiece size, therefore workpiece size is larger, more can embody measurement cost of the present invention; Survey crew is without grasping sleeping carriage operative technique, clamping workpiece centering technology; Measurement result has been got rid of the clamping centering precision of workpiece on equipment, and has solved the limitation that diameter dimension is measured indirectly, has improved measurement precision.
Principle of work: for measured workpiece size, base is measured in design, and base thickness determines on base, there is the parallel circle cylindricality base angle of a pair of mirror image according to measured workpiece axial length, as the guide rail of base, base angle span determines according to measured workpiece outside dimension.When device uses, base angle and measured workpiece are that two parallel lines contact, thereby have guaranteed that clock gauge indicator direction is perpendicular to work centre line.Measure when pony sill is located at benchmark cambered surface the clock gauge number of degrees are made zero and set up benchmark, with two base angles, place and clock gauge indicator, three-point fix basic circle cambered surface radius.When measurement, adjust base decorating position, read the clock gauge number of degrees by clock gauge indicator is erected to concrete point position, can measure concrete measuring point change in radius, with the method can rigorous examination the assembly precision of assembling rotary work piece.At along the circumferential direction mobile measuring equipment of measured workpiece, can obtain continuously change in radius trend, thereby under static state, obtain the circularity situation of rotary work piece.
