Hand-held rapid measurement gauge

Abstract

The utility model is a handheld rapid measurement inspection tool, which relates to the field of inspection tools. It solves the problems of traditional off-the-shelf measurement inspection tools. For traditional tools, multiple size positions need to be independently and quantitatively measured, the single-piece inspection takes a long time, the out-of-tolerance positions cannot be visually identified, and technicians need to repeatedly check the data, resulting in the accumulation and queuing of off-the-shelf parts at the inspection station. Existing inspection tools disperse dimensional tolerances among multiple independent measuring tools, and inspectors need to memorize complex tolerance standards. Its technical features include: a ring-shaped grip; and also include: an anti-slip structure installed on the lower surface of the ring-shaped grip, a support structure installed on the upper surface of the ring-shaped grip, and a detection structure installed on the upper surface of the support structure. During the detection process, if the part can be freely placed, it is qualified. If it cannot be freely placed into the inspection tool and the corresponding position of the part is visually identified as out-of-tolerance, it can meet the rapid identification of incoming inspection. The structure is relatively simple and easy to use.

Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and in particular to a handheld rapid measuring inspection tool. Background Technology

[0002] In the field of machinery manufacturing, incoming inspection of purchased parts is a key step in ensuring product quality.

[0003] Traditional measuring tools for purchased parts require independent quantitative measurement of multiple dimensions, which takes a long time to inspect a single part. It is also difficult to intuitively identify out-of-tolerance locations, requiring technicians to repeatedly check the data. This results in purchased parts accumulating and queuing at the inspection station. Existing tools distribute dimensional tolerances across multiple independent measuring instruments, requiring inspectors to memorize complex tolerance standards. Therefore, it is essential to design a handheld, rapid measuring tool to solve this problem. Utility Model Content
