When the eccentric shaft part is driven to rotate by the turntable, the eccentric disc and the turntable rotate synchronously, so that a measurement probe, the V-shaped reference block and the telescopic supporting rod in the roundness detecting process only move in parallel; when the turntable continuously rotates for one circle, the roundness of the measurement probe on the surface of the part in a 360-degree range is measured by a measurement and control system; and the method is simple, convenient, feasible, scientific, reasonable and high in measurement precision.
Description
Technical field
The invention belongs to mechanical means class, specifically a kind of roundness measurement method of excentric shaft part.
Background technology
In the Precision Machining process of excentric shaft part, the for example grinding of engine crankshaft connecting rod neck, need the roundness deviation of on-position measure excentric shaft part, mainly to adopt V-arrangement reference block mensuration for the method for axle part circularity on-position measure at present, be fixed on V-arrangement reference block by measuring head, in roundness measurement process, utilize supporting construction to make two reference fields of V-arrangement reference block remain circumscribed with measured axis piece surface, thereby obtain the circularity changing value of measured axis piece surface each point by being loaded on the measuring sonde of V-arrangement reference block.But V-arrangement reference block two reference fields and excentric shaft part are kept to reliable and stable circumscribed relation, also there is no a set of more scientific and reasonable, simple method at present.Application number be " 03813741.0 ", name be called " check pin size and the equipment of geometric properties " Patent Application Publication a kind of eccentric pin part roundness measurement method based on servo support, but this supporting structure complexity, adjust difficulty, underaction is convenient; Application number is 201110003560.9, name be called " a kind of measuring method of roundness of eccentric part " Patent Application Publication a kind of excentric shaft part roundness measurement method based on retractable support mechanism, but in its measuring process, the lasting variation of measuring head detection angles make circularity data acquisition and computation process complicated.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of roundness measurement method of scientific and reasonable, simple and easy to do, excentric shaft part that measuring accuracy is high is provided.
Technical scheme of the present invention is as follows:
A kind of roundness measurement method of excentric shaft part, it is characterized in that: a turntable and is installed on base and is measured support, measure on support an eccentric disc is installed, eccentric disc is positioned at turntable top, and this eccentric disc is synchronizeed and is rotated with turntable, excentric shaft part is contained on turntable, a telescopic supporting rod is fixed on eccentric disc by swivel bearing, bearing center is identical with the eccentric throw of eccentric disc centre distance and excentric shaft part, and telescopic supporting rod can freely rotate around swivel bearing; One V-arrangement reference block is installed on telescopic supporting rod, on V-arrangement reference block, measuring head is housed, measuring sonde signal is connected to TT&C system; In the time that excentric shaft part rotates under turntable drives, eccentric disc is synchronizeed and is rotated with turntable, and in rotary course only there is parallel in V-arrangement reference block, measuring sonde, telescopic supporting rod, V-arrangement reference block its two reference field and eccentric element under the effect of telescopic supporting rod inner elastomeric power keep circumscribed, and measuring sonde can be measured the circularity under this state of excentric shaft part; Excentric shaft part turns over a circle continuously, the stroke of telescopic supporting rod and the anglec of rotation ensure that its two reference field of V-arrangement reference block and eccentric element keep circumscribed relation all the time, the measuring sonde being installed on V-arrangement reference block scans a circle around excentric shaft piece surface continuously, TT&C system can collect the fluctuation signal relevant to circularity from measuring sonde, and can draw the circularities within the scope of excentric shaft piece surface 360 degree.
V-arrangement reference block of the present invention is installed on telescopic supporting rod, and telescopic supporting rod is fixed on eccentric disc by swivel bearing, and telescopic supporting rod can freely rotate around swivel bearing.In the time that excentric shaft part rotates under turntable drives, eccentric disc is synchronizeed and is rotated with turntable, make measuring sonde in roundness measurement process, V-arrangement reference block and telescopic supporting rod that parallel only occur, guaranteed that turntable rotational angle and measuring sonde are consistent in the scanning angle of excentric shaft piece surface.When turntable turns over a circle continuously, TT&C system is measured the circularity of measuring sonde within the scope of piece surface 360 degree, and simple and easy to do, scientific and reasonable, measuring accuracy is high.
