Detailed Description

Reference numerals in the drawings of the specification include: the device comprises a detection body 1, a jacking component 2, a centering component 3, a spring 4, a ball 5, a dial indicator 6, a magnetic gauge stand 7, a handle 8, a symmetry line 9, a workpiece 10, a tangent plane 11, a reference hole 12 and a detection hole 13.

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Examples

As shown in fig. 1 to 3, the embodiment provides a runout detection tool, which includes a detection tool body 1, wherein the detection tool body 1 is in a cylindrical shape, a tangent plane 11 is arranged on the cylindrical surface of the detection tool body 1 along a symmetry line 9, centering components 3 are fixed on the tangent plane 11, and the axes of the centering components 3 intersect at the center of the detection tool body 1. The included angle between two centering parts 3 is 120 degrees, and threaded connection between centering part 3 and the body of examining 1 in this embodiment, and centering part 3 and work piece 10 contact one side be the arc surface to avoid centering part 3 fish tail work piece 10, be convenient for examine the rotation of body 1 simultaneously.

Examine and run through on the body 1 and seted up the mounting hole, the axis and the coincidence of symmetry line 9 of mounting hole, the mounting hole is kept away from the downthehole spheroid 5 of having placed of 3 one ends of centering part, and 5 one end opening apertures of spheroid are placed to the mounting hole and are less than 5 diameters of spheroid to avoid spheroid 5 to go out.
