Self-aligning and leveling table for high-precision cylindricity meter

Abstract

The invention belongs to the fields of measurement and detection, particularly relates to a centering and leveling work platform for a high-precision cylindricity measuring instrument and aims to provide the centering and leveling work platform which has the advantages of simpler structure, small regulating resistance and high feeding precision. The centering and leveling work platform comprises a centering device, a leveling device and a support device, wherein the centering device and the leveling device are mounted on the support device, the centering of the work platform is implemented by the centering device, and the leveling of the work platform is implemented by the leveling device. Centering is carried out through the adoption of a bevel gear steering box 5, a centering worm gear box 7 and a centering feeding head 22, and the input-output angle of the worm gear box is converted by a bevel gear. Besides, a spring is utilized to apply a certain pre-tightening force, centering shift is transmitted through the rolling of steel balls in a centering ball disc, and sliding friction is replaced by rolling friction, so that the resistance is reduced, and the error is reduced to a certain degree, therefore, the centering precision is improved.

Description

technical field [0001] The invention belongs to the field of measurement and detection, and in particular relates to a centering and leveling workbench for a high-precision cylindricity meter. Background technique [0002] In some technical fields, precision parts such as holes and shafts on servo mechanisms and inertial devices require accuracy at the sub-micron level, and shape accuracy requirements at the tens of nanometer level, and their accuracy directly affects servo mechanisms, Quality and reliability of inertial devices. To produce such high-precision precision parts, a high-precision cylindricity meter is required for calibration. Therefore, the accuracy of the cylindricity meter directly affects the detection of precision parts. [0003] The centering and adjusting platform is the key part of the cylindricity meter. It is connected with the rotating spindle and is mainly used to adjust the eccentricity and inclination of the workpiece. These adjustments are extr...

Problems solved by technology

[0004] At present, the centering and leveling worktables of domestic and foreign cylindricity instruments are mainly divided into two types: manual and automatic. Although the adjustment efficiency of automatic adjustment is relatively high, the motor used will generate heat and vibration during the working process, which will affect the The measurement results are affected, and at the same time, the structure is complex and the cost is high, while the manual adjustment can reduce the manufacturing cost and ensure high alignment and leveling accuracy

[0005] The existing manual centering and leveling workbench has a complex structure, heavy weight, and low feed accuracy. The resistance encountered during the centering process is relatively large, which greatly affects the measurement accuracy of cylindricity
