Raceway groove depth detection gauge

Abstract

The invention discloses a raceway groove depth detection gauge comprising a test sleeve; a groove is arranged on the bottom of the test sleeve; the bottom of the groove is provided with the first through hole; the groove and the first through hole can form a mounting through hole; a test rod is arranged in the mounting through hole; the test wall of the test sleeve is provided with a compact screwhole connected with the first through hole; a compact screw is arranged in the compact screw hole, and compacted and connected with the side wall of the test rod; a stop rod is arranged in the grooveand matched with the groove; a measuring bar is sleeved by a pressure spring; one end of the pressure spring is compacted and connected with the end face of the stop rod, and the other end is compacted and connected with the end face of a gland; the measuring bar is matched with the second through hole. A steel ball of the standard specifications and the gauge are combined so as to test the groove depth of the parts; the surface of the steel ball is in an arced shape, so the steel ball can be precisely filled in the arc-shaped groove on the bottom of the part groove, thus precisely representing the height of the arc-shaped groove, and reaching the determination accuracy.

Description

technical field [0001] The invention belongs to the field of parts processing and testing, and relates to a measuring tool for testing the depth of raceway grooves. Background technique [0002] In the production process of parts, for parts containing grooves, the depth of the groove determines the quality of the parts, which is very important for the detection of the groove depth of the parts. The existing measuring tools directly use a single casing gauge or indicator It is not possible to accurately measure parts with arc-shaped grooves at the bottom of grooves. At the same time, parts with deep grooves need to be replaced with measuring tools, and the measurement process is cumbersome. Contents of the invention [0003] The object of the present invention is to provide a measuring tool for detecting the depth of raceway grooves. The measuring rod of the measuring tool is covered with a compression spring. For grooves of different depths, the measuring rod is pressed, a...
