Abstract

The invention relates to an instrument capable of measuring a surface profile of a complicated revolving part. The instrument comprises a worktable and a profilemeter arranged on the worktable, wherein the profilemeter is composed of a Z-axis air floatation stand column arranged on the worktable, an X-axis air floatation guide rail arranged on the Z-axis air floatation stand column, a sensor and a survey probe arranged on the X-axis air floatation guide rail, and a mobile platform installed on the worktable by guide rails; the survey probe is parallel to the X-axis of the worktable. The instrument further consists of a three-dimensional platform arranged on the worktable, wherein the three-dimensional platform is provided with clamp claws capable of clamping parts to be measured, the center shaft of the three-dimensional platform is arranged on a straight line on which the survey probe is located. The instrument can realize the simultaneous measurement of profile and circularity.

Description

A kind of instrument of measuring surface profile of complicated revolving parts
Technical field
The present invention relates to a kind of surveying instrument, relate in particular to a kind of instrument of measuring surface profile of complicated revolving parts.
Background technology
When the revolving parts surface profiles such as measurement internal rotor, ratchet, it is less that roundness measuring equipment is measured range, can not satisfy the measurement requirement, although contourgraph can satisfy the requirement of measuring range, can not realize the measurement to whole solid of revolution.
Summary of the invention
The object of the invention provides a kind of instrument of measuring surface profile of complicated revolving parts, and it has solved in existing roundness measuring equipment or the contourgraph technical matters that can not measure surface profile of complicated revolving parts.
Technical scheme of the present invention is:
A kind of instrument of measuring surface profile of complicated revolving parts, comprise worktable, be located at the contourgraph on the worktable, described contourgraph comprises the Z axis air supporting column that is arranged on the worktable, be arranged on X-axis air-float guide rail on the Z axis air supporting column, be arranged on sensor on the X-axis air-float guide rail and chaining pin, by the mobile platform of guide rails assembling on worktable; Described chaining pin is parallel with the X-axis of worktable; Its special character is: described instrument also comprises the three-dimensional platform that arranges on the worktable, but is provided with the jaw of clamping tested part on the described three-dimensional platform; The central shaft of described three-dimensional platform is positioned on the straight line of chaining pin place.
Above-mentioned jaw is scroll chuck.
Technique effect of the present invention is:
1, can when realizing profile and circularity, measure by an instrument.
2, can measure simple profile or complex revolving body surface profile.
Description of drawings
Fig. 1 is the structural representation of the present invention when measuring the complex revolving body surface profile;
Fig. 2 is the structural representation of the present invention when measuring simple profile;
Reference numeral is as follows: 1-worktable, 2-X axle air-float guide rail, 3-chaining pin, 4-tested part, 5-scroll chuck, the three-dimensional platform of 6-, 7-mobile platform, 8-sensor, 9-Z axle air supporting column, 10-guide rail.
Embodiment
Referring to Fig. 1 and Fig. 2, the present invention can realize respectively the measurement to profile and circularity on an instrument.When measuring tested part circularity, mobile platform 7 is moved to a end away from sensor 8 along guide rail 10, tested part 4 is placed on the scroll chuck 5 of three-dimensional platform 6, adjust the sensor 8 on tested part 4 and the contourgraph, and then rotate three-dimensional platform 6 and just can realize measurement to circularity, this measuring principle is identical with common roundness measuring equipment, just the sensor on original roundness measuring equipment is substituted with the sensor on the contourgraph.
When measuring the tested part profile, mobile platform 7 is shifted to an end of close sensor 8 along guide rail 10, the profile measurement frock is placed on the mobile platform 7, and tested part to be measured on the clamping, adjust the contact of the sensor 8 on the contourgraph perpendicular to the tested part surface, X-axis air-float guide rail 2 on the mobile contourgraph can be realized the measurement to the tested part working profile, and this measuring principle is identical with common contourgraph.
Principle of work of the present invention:
But the present invention is circularity or the profile of independent measurement tested part not only, but also can measure the profile of complex revolving body.The measurement problem that this has solved the complex revolving body surface profiles such as rotor and ratchet has improved measurement efficient simultaneously.For the measurement of the surface profile of complicated revolving parts such as internal rotor and ratchet the time, the present invention combines and realizes measuring simultaneously circularity and profile by having roundness measuring equipment and contourgraph now.At first tested part 4 is placed on the scroll chuck 5 in the three-dimensional platform 6 as shown in Figure 1, adjust the sensor 8 on the contourgraph, so that the centre of gyration is crossed at sensor 8 centers, wherein sensor 8 can be inductance sensor, so that the chaining pin 3 on the contourgraph is over against the center of three-dimensional platform 6, wherein the gauge head on the chaining pin 3 contacts with tested part 4, the utmost point on tested part 4 surfaces is directly changed passing to sensor, and is transferred in the computing machine.Then begin to rotate three-dimensional platform 6, utilize the sensor measurement circularity on the contourgraph, simultaneously because the rotation of three-dimensional platform 6 self, so that the tested part 4 that is fixed thereon also rotates thereupon, then the sensor on the contourgraph can collect tested part profile when rotated, and then reaches the effect that records simultaneously the tested part profile.
The present invention utilizes the roundness measuring equipment scan method to the scanning of complex revolving body surface profile, utilizes contourgraph sensor measurement structure to carry out the data acquisition outline data, thereby has realized the measurement to complex revolving body surface profiles such as rotor and ratchets.
