Embodiment Construction

[0023] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The principle of three-point method error separation technology is as follows: figure 1 shown. The three sensors P0, P1, and P2 are installed at different positions on the circumference of the workpiece, and the angles between the three sensors are α and β respectively. It is required that the installation axes of the three sensors intersect at the center of the circle O, which is also the origin and origin of the coordinate system XOY. Rotate the center of the table. When measuring, the sensor is fixed, and the workpiece to be measured is driven by the rotary table to make a rotary motion. According to the output equation of the measurement results and the error separation equation of the three-point method, the roundness error of the workpiece and the rotation error of the rotary axis can be separated by using appropriate paramete...

Abstract

The invention relates to a sensor installation and adjustment system and a laser leveling reference device. The sensor installation and adjustment system includes at least three sensor installation and adjustment devices and a laser leveling reference device for installing lasers. The sensor installation and adjustment device is provided with The height adjustment part and the horizontal alignment mechanism for adjusting the level of the sensor fixing seat, the horizontal alignment mechanism includes the target positioning hole set on the front mounting plate and the target marking line set on the rear mounting plate, the distance between the target positioning hole and the target marking line The wiring is arranged in parallel with the sensor. The laser leveling reference device of the present invention is provided with at least three height adjustment components arranged at intervals around the circumference for adjusting the level of the laser fixing seat. The system and device of the present invention can quickly make the measurement axes of multiple sensors coplanar and installed at the same center, improve the efficiency and accuracy of sensor installation and positioning, and further ensure the measurement accuracy of roundness error and rotation error.

Description

technical field [0001] The invention belongs to the technical field of rotary error separation of rotary shafts, and in particular relates to a sensor installation and adjustment system and a laser leveling reference device. Background technique [0002] Roundness error is one of the important indicators to measure the shape accuracy of cylindrical parts. The size of the roundness error of parts seriously affects the working performance and motion performance of parts, and affects the overall performance of mechanical equipment. When measuring the roundness error of parts and the rotation accuracy of the rotary axis of the machine tool on site, error separation technologies such as the three-point method in the time domain and the three-point method in the frequency domain are often used to realize the separation of the axis rotation error and the roundness error of the part. Eccentric characteristics, and has a high test accuracy. Since the three-point roundness error sepa...
