Quick detection device for sizes of inner cavities of flywheel casings

Abstract

The invention discloses a quick detection device for sizes of inner cavities of flywheel casings. The quick detection device comprises a positioning reference object, a mandrel is rotationally mounted in the center of the positioning reference object, an adjusting support is fixedly mounted at the upper end of the mandrel, an adjusting bolt is arranged on the adjusting support, an inspection device is fixedly mounted at the front end of the adjusting support via the adjusting bolt, and a roller bearing is arranged between the mandrel and the reference object. The quick detection device is simple in structure and simple, convenient and speedy to operate, and detection results are visual.

Description

technical field [0001] The invention mainly relates to a checking tool for quickly detecting the inner cavity size of flywheel housings of various diesel engines. Background technique [0002] With the increase in the variety of diesel engines, there are more than a dozen types of flywheel housings for multi-cylinder diesel engines, with different thicknesses and inner cavity diameters. The inner cavity of the detection flywheel housing is deeper and the diameter is larger, which cannot be fully tested with conventional measuring tools; the inner cavity diameter directly affects Whether the flywheel ring gear interferes with the inner cavity wall after assembly, and the thickness (inner cavity depth) affects whether the flywheel can be assembled in place; in routine inspection, local measurement is performed with a depth gauge or a vernier caliper, which cannot ensure the same thickness within the diameter range; It is very difficult to detect the diameter and thickness of t...

[0002] With the increase in the variety of diesel engines, there are more than a dozen types of flywheel housings for multi-cylinder diesel engines, with different thicknesses and inner cavity diameters. The inner cavity of the detection flywheel housing is deeper and the diameter is larger, which cannot be fully tested with conventional measuring tools; the inner cavity diameter directly affects Whether the flywheel ring gear interferes with the inner cavity wall after assembly, and the thickness (inner cavity depth) affects whether the flywheel can be assembled in place; in routine inspection, local measurement is performed with a depth gauge or vernier caliper, which cannot ensure the same thickness within the diameter range; It is very difficult to detect the diameter and thickness of the inner cavity with a larger diameter. In order to solve this type of detection problem, a inspection tool for the rapid detection of the inner cavity size and depth of the flywheel housing is designed.
