Inner hole radial circle run-out detecting tool

Abstract

The invention discloses an inner hole radial circle run-out detecting tool, which comprises a supporting rod and a hollow tube. The rear end of the supporting rod is inserted into the front end of the hollow tube, the supporting rod is provided with a movable sleeve, the movable sleeve with the adjustable position is fixed on the supporting rod, the hollow tube is provided with a fixed sleeve, a spring is disposed between the movable sleeve and the fixed sleeve, a rod head is arranged at the front end of the supporting rod, a base is arranged at the rear end of the hollow tube, a radial bearing is disposed on the lower surface of the rod head, two radial bearings are disposed on the lower surface of the base, a position-adjustable dial indicator support is disposed on the hollow tube, and a dial indicator is arranged on the dial indicator support. The inner hole radial circle run-out detecting tool has the advantages of lightness, simplicity, convenience in movement and service and stableness and reliability in measurement, has good generality, and is applicable to measuring inner circles with different diameters.

Description

technical field [0001] The invention relates to a detection tool, in particular to a tool for detecting radial runout of an inner hole. Background technique [0002] In the process of mechanical production and manufacturing, in order to ensure the concentricity of parts during assembly, it is often necessary to measure the radial circular runout of the inner hole of a part relative to a given reference inner circle to determine its concentricity. At present, the concentricity of the parts can be well guaranteed by the precision of the machine tool during the processing of the parts, and it can be easily measured online, but it is more complicated to measure the concentricity of the parts during the assembly process. The structures are relatively complex, and the detection results are not very accurate and stable, which will have a negative impact on the assembly of the workpiece. In addition, the current inner hole radial runout detection tool is not universal, and it is of...

At present, the concentricity of the parts can be well guaranteed by the precision of the machine tool during the processing of the parts, and it can be easily measured online, but it is more complicated to measure the concentricity of the parts during the assembly process. The structure is relatively complex, and the detection results are not very accurate and stable, which will have a negative impact on the assembly of the workpiece

In addition, the current inner hole radial runout detection tool is not universal, and it is often necessary to design different measurement tools for parts with different diameters, which will also increase the production cost of the enterprise.
