Silencing cavity bottom hole depth gauge

Abstract

The invention relates to the technical field of cavity bottom holes, in particular to a depth gauge for the bottom hole of a muffler cavity, which includes a measuring rod and a support sleeve. A through hole is provided in the inner cavity of the support sleeve, and a cylindrical pin is arranged in the support sleeve. The measuring rod includes a moving rod, a transparent rod handle and a rod sleeve, the lower end of the moving rod is connected with a plug, the upper end of the transparent rod handle is connected to the lower end of the rod sleeve, and the moving rod is inserted into the transparent rod handle And in the rod sleeve, the upper end shaft of the moving rod is connected with a pull ring. The depth gauge of the bottom hole of the muffler chamber has a simple structure. It is convenient to measure whether the size and depth of the cylindrical pin meet the requirements by adding a measuring rod. The detection and measurement of the depth realizes the scope of use of the detection equipment. The pull ring is used to facilitate the pulling of the moving rod, thereby quickly detecting the threaded hole and improving the detection efficiency. By adding balls, it is convenient for the detection equipment to move up and down in the support sleeve.

Description

technical field [0001] The invention relates to the technical field of cavity bottom holes, in particular to a depth gauge for a bottom hole of a muffler cavity. Background technique [0002] In mechanical parts, the threaded hole detection tool of the part is a tool to detect whether the part is qualified or not, but the traditional method of detecting the depth of the cavity bottom hole is to insert the detection tool into the threaded hole, but some threaded holes will change accordingly. Small, so it is not convenient to detect the depth in the threaded hole. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the defects of the prior art and provide a depth gauge for the bottom hole of the muffler chamber. The depth gauge for the bottom hole of the sound-absorbing cavity has the characteristics of simple structure, convenient use, and the ability to stretch and detect the depth of the threaded hole.
