Problems solved by technology

The most advanced detection method in the existing technology is a three-dimensional coordinate detector. Although the detector is accurate in measurement, the detection cost is high and the work efficiency is low, so it is not suitable for the inspection tool on the production site.
In conventional production, a mandrel plus a dial indicator is used for comparative testing. The inspection tool can also be used for accurate measurement. The disadvantages are that the installation of the inspection tool is complicated, the inspection operation is difficult, and the efficiency is low. It cannot meet the online inspection requirements of mass production.

Embodiment Construction

[0012] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0013] The paired and mutually perpendicular hole center distance inspection tool shown in the accompanying drawing includes a positioning mandrel 3 standing on a flat workbench 1 and matching with the vertical hole of the workpiece 4, and a mandrel 2 matching with the horizontal hole of the workpiece 4 . The positioning mandrel 3 is tangent to the outer wall of the middle section of the mandrel 2 . This embodiment is a test tool for the center distance of the pump body of the motorcycle oil pump, in which the shaft section of the positioning mandrel 3 with an outer diameter of Φ21.4mm cooperates with the hole at the vertical position of the oil pump to determine the position of the oil pump on the flat workbench 1, and then Insert the matched mandrel 2 from the horizontal hole on the right side of the oil pump, locate the mandrel 3 to...

Abstract

The invention discloses a detection tool for center distance between matched and mutually perpendicular holes. The detection tool comprises a positioning core shaft which is vertically arranged on a flat-plate worktable and is matched with a workpiece perpendicular hole, as well as a mandrel matched with a workpiece horizontal hole. The sum of the radius and deviation of the positioning core shaft and the middle segment of the mandrel is equal to a designed value of the center distance between matched and mutually perpendicular holes of a detected workpiece. In actual detection, the positioning core shaft and mandrel intersect, and errors of the center distance are judged according to the tangency condition of the outer walls of the two. The detection tool having the advantages of simple structure, easy manufacture and fast measurement is particularly suitable for on-line detection in mass production field.

Description

technical field [0001] The invention relates to a checker, in particular to a checker for paired detection and the center distance between vertical holes. Background technique [0002] There are often paired and mutually perpendicular holes on the shell and box parts. These holes require high relative position accuracy and are difficult to process. Such holes are mandatory inspection items during the production process. The most advanced detection method in the prior art is a three-dimensional coordinate detector. Although the detector is accurate in measurement, it has high detection cost and low work efficiency, and is not suitable for the inspection tool on the production site. In conventional production, a mandrel plus a dial indicator is used for comparative testing. The inspection tool can also be used for accurate measurement. The disadvantages are that the installation of the inspection tool is complicated, the inspection operation is difficult, and the efficiency is...
