After acquiring partial data using the device, software can be used to calculate the thickness of a curved-surface thin wall, thereby accelerating measurement, achieving high precision, and greatly improving the precision and quality in processing related components. The device is particularly suitable for the processing of radome.
Description
Technical field
The utility model relates to a kind of geometric parameter measurement device, relates in particular to a kind of measurement mechanism of 3 D complex curved surface Thin-wall Revolving Part normal direction thickness.
Background technology
Antenna house is the 3 D complex curved surface Thin-wall Revolving Part of being made by hard brittle material, electricity thickness is the antenna house electrical performance indexes, it is relevant to the specific inductive capacity of thickness and material with geometric method, the electric thickness error foot designing requirement of the semi-finishing irdome day after tomorrow, need carry out accurate reconditioning to profile in the antenna house, compensate electric deviation by the geometric method that changes the cover wall to thickness, its processing belongs to Free-Form Surface Machining.Thereby geometric method is the key of accurate reconditioning to the measurement of thickness.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of normal direction thickness rapid measurement device, measures inconvenience, the defective that precision is low in the prior art to solve.
A kind of normal direction thickness rapid measurement device comprises three coordinate measuring machine, is 3 micrometric displacement touch sensors of center of circle annular array (1) with the measuring head on the three coordinate measuring machine (2).
The length of described micrometric displacement touch sensor (1) is than the long 10mm of measuring head (2).
Beneficial effect
The utility model is by after measuring partial data, and available software calculates the thickness of curved surface thin-walled, and measuring speed is fast, and the precision height can improve the machining precision and the quality of correlated parts greatly, is particularly suitable for being applied to the processing of antenna house.
Description of drawings
Fig. 1 is the utility model structural representation;
Schematic diagram when Fig. 2 is measurement.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of normal direction thickness rapid measurement device comprises three coordinate measuring machine, is 3 micrometric displacement touch sensors 1 of center of circle annular array with the measuring head on the three coordinate measuring machine 2, described micrometric displacement touch sensor 1 is slightly longer than measuring head 2, and its length difference h is 10mm.
The shift value that three micrometric displacement touch sensors 1 that the utility model is evenly arranged with circumferencial direction 120 degree are exported when the measuring head 2 of three coordinate measuring machine (CMM) touches part, because the measuring mechanism size is definite, obtain contacting the volume coordinate of three points on the part with sensor by the coordinate figure of CMM measuring head, the shift value that is superimposed with three micrometric displacement touch sensors again obtains three volume coordinate points, the plane parallel that these three points make up is in the section, thereby the normal direction angle on the plane that makes up is the normal direction of institute's measuring point, then the CMM measuring head is adjusted to this normal direction theta alignment outline coordinate points by the progressive contact measurement of interior profile, coordinate figure by CMM inside and outside contour point that measuring head is surveyed can calculate 2 three-dimensional distance, be the thickness of the normal orientation of tested point, revolving parts with smooth surface can use this measuring system to carry out continuous coverage, deposit data in buffer memory, obtain the coordinate of each point and the normal vector of this point in real time by software processes.
As shown in Figure 2, if tested part is a hollow hemisphere, shift value should be identical shown in the triple motion touch sensor so, thereby the plane that three points contacting with part of sensor make up is the section, the normal in section is the normal direction of measured point, then measuring head is transferred to this normal direction and is aimed at the point on the profile in the outline measured point measurement part, the three-dimensional distance that obtains inside and outside contour point then is a normal direction thickness, and theoretical precision is error free.When tested part was the complex profile thin-walled revolution workpiece, the measuring mechanism errors of principles was relevant with the leg-of-mutton area that micro-displacement sensor three contacts are formed, and area is more little, and error is more little; Also relevant with the curvature of curved surface pace of change.Can set up Model Calculation and go out this error.
Claims (2)
