Embodiment Construction

[0044] The specific implementation of the roundness measuring instrument and its measuring method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] See attached figure 1 And attached figure 2 , a swing cylinder 2 is fixedly installed on the base 1 of the roundness measuring instrument, and the swing cylinder 2 is controlled by a pneumatic unit to realize rotation and swing. The fixed part of the swing cylinder 2 is fixedly connected with the base 1, and the swing part of the swing cylinder 2 is fixedly connected with a platform3. A sensor bracket 5 is arranged on the platform 3 through the connecting plate 4. The sensor bracket 5 is a hollow structure connected up and down. Four displacement sensors 6 are arranged on the sensor bracket 5. The four displacement sensors 6 are arranged in a cross shape, and the two displacement sensors are arranged in the same position. On a straight line, perpendicular to each o...

Abstract

The invention relates to the technical field of machining and detection and discloses a roundness measuring instrument comprising a base and a signal processing unit. A sensor support that is of an up-down-through hollow structure is arranged on a platform arranged on the base, and four displacement sensors which are in crossed arrangement are mounted on the sensor support. A mandrel is fixedly arranged on the base and penetrates the platform to extend into the sensor support. A mount is arranged at the top end of the mandrel and located right below the four displacement sensors. The invention further discloses a measuring method of the roundness measuring instrument. By means of four-point synchronous measurement, the measurement speed is increased greatly.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and detection, in particular to a roundness measuring instrument and a measuring method thereof. Background technique [0002] The roundness measurement of existing cylindrical parts or tubular parts is all completed by a roundness meter, which is a measuring tool for measuring the roundness error of a workpiece by using the rotary axis method. The roundness meter is divided into two types: sensor rotary type and table rotary type. [0003] The existing roundness meter has slow detection speed, high equipment cost and high requirement for ambient temperature, and is suitable for laboratory environment applications. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned technical problems, and provide a roundness measuring instrument and its measuring method. Four displacement sensors are used to measure the four directions of the par...
