Simple depth touch gauge

Abstract

The invention relates to a simple depth touch gauge. The simple depth touch gauge comprises a touch gauge through end, a measuring body, a first tensioning sleeve, a three-color handle, a second tensioning sleeve and a touch gauge stop end, wherein the measuring body is connected with the touch gauge through end in a sliding manner, and capable of sliding along the axial direction and rotating along the radial direction of the touch gauge through end, respectively; the touch gauge through end is fixed at one end of the three-color handle by the first tensioning sleeve; and the touch gauge stop end is fixed at the other end of the three-color handle by the second tensioning sleeve. Threads are arranged on each of the touch gauge through end and the touch gauge stop end; and the each of the touch gauge through end and the touch gauge stop end is smooth. The simple depth touch gauge has the advantages of being simple, compact and reasonable in structure, convenient to operate, low in manufacturing cost, high in detecting efficiency and the like. The measuring body can rotate on the through end, so that the step surface of the measuring body faces operating personnel for convenience in vision or touch judgment of the operating personnel; and moreover, the operating personnel use fingers to touch to improve detecting precision and reduce error in judgment.

Description

technical field [0001] The invention relates to a touch gauge, in particular to a simple threaded (or smooth) depth touch gauge, which belongs to the technical field of measurement and detection. Background technique [0002] In the existing technology, the processing of internal thread or internal hole is a very common process in the machining process. Internal thread mainly has two detection parameters of internal thread pitch diameter (or internal hole diameter) and depth. Internal thread pitch diameter (Roughly machined inner hole diameter) is usually qualitatively tested with a through / stop thread gauge (smooth gauge); the common method for thread (or inner hole) depth is to process some size grooves on the through end of the plug gauge for qualitative testing, and its detection accuracy Low, the detection results often cause judgment errors due to the position of the threaded hole or inner hole affecting the operator's vision, and the method is not suitable for threade...
