Abstract
The invention belongs to the field of mechanical methods and particularly to a method for measuring the roundness of an eccentric part. The method is characterized in that the eccentric part is installed on a rotating table, a V-shaped reference block is installed on a telescopic support rod, the support rod is mounted on a reference frame having a determined distance to the center of the rotating table, and the support rod can rotate freely within a certain angle range around the reference frame; a measuring probe is mounted on the V-shaped reference block, and a signal of the measuring probe is connected to a measurement and control system; when the eccentric part revolves under the drive of the rotating table, two reference surfaces of the V-shaped reference block can be always kept in externally tangent relation with the eccentric part under the action of elastic part of the telescopic support rod; when the eccentric part continuously revolves for one circle, the measuring probe mounted on the V-shaped reference block continuously goes around the surface of the part for one circle, the measurement and control system can acquire a fluctuation signal related to the roundness of the measured eccentric part and further get the roundness of the surface of the eccentric part within a 360-degree range. The method is simple and easy to operate, scientific and reasonable, and has high measurement precision.
Description
Technical field
The invention belongs to the mechanical means class, specifically is a kind of measuring method of eccentric element circularity.
Background technology
In machine-building processing, the for example grinding of part, the circularity that needs the on-line measurement part, the measuring method that is used for the online circularity of mechanical component at present mainly is to adopt V-arrangement reference block mensuration, being about to measuring head is fixed on the V-arrangement reference block, in the roundness measurement process, it is circumscribed to utilize physical construction that two reference fields of V-arrangement reference block are remained with tested part, thereby obtains the circularities of tested part each point by being loaded on measuring sonde on the V-arrangement reference block.Yet V-arrangement reference block two reference fields and eccentric element to be kept reliable and stable circumscribed relation, also not have more scientific and reasonable, the simple method of a cover at present.Application number is that patented claim that " 03813741.0 ", name are called " checking the size of pin and the equipment of geometric properties " discloses and a kind of the V-arrangement reference block combined the measurement of finishing eccentric element each point circularity with a servo support, yet should overlap the supporting structure complexity, it is limited that it utilizes parallel-crank mechanism to follow the servo-actuated precision that eccentric element rotates, and need to adjust structural parameters according to measuring object, underaction is convenient.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of measuring method of scientific and reasonable, simple and easy to do, eccentric element circularity that the servo-actuated precision is high is provided.
Technical scheme of the present invention is as follows:
A kind of measuring method of eccentric element circularity, it is characterized in that: eccentric element is contained on the turntable, the V-arrangement reference block is loaded on the support bar that can stretch, and this support bar is installed on the benchmark frame of determining with turntable centre distance, and support bar can rotate freely in the certain angle scope around the benchmark frame; Install and measure probe on the V-arrangement reference block, the measuring sonde signal is connected to TT﹠C system; When eccentric element when turntable drives turning down, V-arrangement reference block two reference fields under retractable supports bar resilient force can remain circumscribed relation with eccentric element; When eccentric element turns over a circle continuously, be installed on measuring sonde on the V-arrangement reference block continuously around piece surface one circle, TT﹠C system can collect and the relevant fluctuation signal of tested eccentric element circularity, and can draw the circularity in the 360 degree scopes of eccentric element surface.
V-arrangement reference block of the present invention is installed on the support bar that can stretch, support bar can rotate freely at certain angle around the benchmark frame, when eccentric element when turntable drives turning down, V-arrangement reference block two reference fields and eccentric element remain circumscribed relation, thereby measure the circularity of measuring sonde in piece surface 360 degree scopes by TT﹠C system, simple and easy to do, scientific and reasonable, the measuring accuracy height.

Fig. 1 is a synoptic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of measuring method of eccentric element circularity is characterized in that:
A, eccentric element 2 is contained on the turntable 1;
B, V-arrangement reference block 7 is loaded on the support bar that can stretch 4, and this support bar 4 is installed on the benchmark frame 5 of determining with turntable center 8 distances, between support bar 4 and the benchmark frame 5 torque spring 9 is arranged, support bar 4 can be rotated freely in the certain angle scope around benchmark frame 5;
C, on V-arrangement reference block 7, install and measure the probe 6, measuring sonde 6 signals are connected to TT﹠C system;
D, when eccentric element 2 when turntable 1 drives turning down, V-arrangement reference block 7 two reference fields 3 under retractable supports bar 4 and torque spring 9 effects keep circumscribed with eccentric element 2, measuring sonde 6 can be measured the circularity of this point of eccentric element;
E, under driving, turntable 1 turns over a circle continuously when eccentric element 2, the measuring sonde 6 that is installed on the V-arrangement reference block 7 is measured a circle around piece surface continuously, TT﹠C system can collect the fluctuation signal relevant with tested part circularity, and can draw the circularity in the 360 degree scopes of eccentric element surface.
7 liang of reference fields of V-arrangement reference block 3 can keep circumscribed relation all the time with eccentric element 2 when the stroke of support bar 4 of the present invention and pendulum angle must keep eccentric element to rotate a circle.
Between support bar 4 of the present invention and the benchmark frame 5 torque spring 9 is arranged, benchmark frame 5 positions remain unchanged in the measuring process, and measured workpiece drives turning down and automatic stroke and the pendulum angle that forms support bar 4 at turntable 1.
Support bar 4 of the present invention has straight-line guidance mechanism, and obtains telescopic resilience power by spring, oil cylinder, cylinder etc.
