Embodiment
[0028] Example: For easily deformable rod parts.
[0029] First remove the water baffle on the probe box, the workpiece passes through the probe box, rotate and then tighten the two ends of the workpiece with three-jaw chucks respectively, and ensure that the water baffle is inserted into the groove of the probe box, and then rotate the hand wheel wire The bar drives the tension slide plate to move to the left, properly tensions the workpiece, fills the probe box with water to make the ultrasonic waves propagate in the solid-liquid two-phase, and it is best to be equipped with a water circulation device during the measurement process to ensure the water level in the probe box Meet the requirements of normal measurement.
[0030] 1. For the measurement of the diameter of solid, plastic, and easily deformed slender rod parts: first, turn on the probe to emit sound waves, adjust the outer ring and inner ring to a suitable eccentric phase and probe distance, and observe the echo w...

The invention belongs to the technical field of part non-damage detection of a special rod class, and particularly relates to a cross section measuring device of a high-ductility long-thin rod part. The cross section measuring device of the high-ductility long-thin rod part solves the problems that a rod-class part which has the characteristics of being high in ductility, large in major axis ratio and easy to deform does not have a mature detection method and a device. The cross section measuring device of the high-ductility long-thin rod part comprises a plurality of ultrasonic probes, a workpiece clamping and tensioning device, a main driving system, a feed driving system and a probe fine adjusting mechanism, wherein the workpiece clamping and tensioning device can conduct positioning and tensioning of a workpiece, the main driving system can enable the workpiece to rotate and enable two ends of the workpiece to has the same angular speed, the feed driving system can enable the ultrasonic probes to move to the other end of the workpiece from on end of the workpiece, and the probe fine adjusting mechanism can adjust the heights of the ultrasonic probes and the distance between the probes and the workpiece. Compared with the prior art, the cross section measuring device of the high-ductility long-thin rod part has the advantages of solving the problems that the rod-class part which has the characteristics of being high in ductility, large in major axis ratio and easy to deform is low in efficiency, and difficult in implementation, deformation affects measuring results, detection precision can not be ensured and the like.
Description
technical field [0001] The invention belongs to the technical field of non-destructive testing of special rod parts, and in particular relates to a section measuring device for high-plastic slender rod parts. Background technique [0002] In a special occasion, it is necessary to measure the cross-sectional dimension parameters of a special rod part. This kind of workpiece has the following characteristics: the aspect ratio is large, generally in the About, the outer diameter of the workpiece is about ; The plasticity is very good, and severe bending deformation occurs when clamping with a conventional three-jaw chuck; the process requires sampling inspection of the inner diameter, wall thickness, and other parameters of the workpiece section. [0003] Insufficient rigid stability leads to a large degree of bending deformation, while the rotation of the workpiece will cause large torsional deformation, making the measurement impossible. Therefore, the workpiece needs to ...
