Inner hole chamfer depth gauge

Abstract

The invention provides an inner hole chamfer depth gauge. A gauge body is a hollow cylinder; the middle upper portion of a sliding measuring head is a cylindrical sliding guide column which is matched with the gauge body, a flat groove is arranged on a side of the sliding guide column, and the lower portion of the sliding measuring head is a cone measuring head for detecting chamfer depths; and a threaded through hole is arranged on a side of the gauge body, a limiting screw is arranged in the threaded through hole, and the top of the limiting screw is screwed in the flat groove of the sliding guide column so as to limit an axial movement range of the sliding measuring head in the gauge body. The inner hole chamfer depth gauge has the advantages of convenience in use, easiness in repair, low cost, long service life, measurability and the like, and is particularly applicable to comparing and measuring chamfer depths of deep inner holes difficultly observed by eyes or inner holes of blind holes, real-time monitoring to chamfer depths of inner holes on a production line is realized, and production efficiency is improved.

Description

technical field [0001] The invention belongs to measuring and testing equipment in the field of mechanical processing, in particular to an inner hole chamfering depth gauge. Background technique [0002] In the field of mechanical processing, in a series of workpieces containing oil passages and subjected to high pressure, such as connecting bodies, there will be many deep inner hole chamfers that are difficult to observe with the naked eye. The workpieces are sealed by these chamfers to achieve greater pressure. The purpose of preventing the oil passage from leaking under high pressure is that these chamfer depths have relatively precise tolerance requirements and must be inspected. At present, for the detection of the chamfering depth of the inner hole, the conventional method of dissecting the workpiece destroys the workpiece, and batch detection cannot be done; the expensive profiler cannot realize constant detection on the production line, and the detection frequency is...

Problems solved by technology

At present, for the detection of the chamfering depth of the inner hole, the conventional method of dissecting the workpiece destroys the workpiece, and batch detection cannot be done; the expensive profiler cannot realize constant detection on the production line, and the detection frequency is low, requiring professional detection

Chinese Patent Utility Model Specification No. CN2864577Y provides a kind of inner hole chamfer depth comparison block, which is used to measure and compare the depth of inner hole chamfer, but it is not applicable to the deeper inner hole chamfer depth measurement which is difficult to observe by naked eyes.
