Composite threaded gauge achieving rapid detection

Abstract

The invention discloses a composite threaded gauge achieving rapid detection. The composite threaded gauge comprises a shank part, the front end of the shank part is a go end, the rear end of the shank part is a not-go end, the outer side of the not-go end is provided with a thread, and a threaded not-go gauge is formed; the outer side of the go end is provided with two sections of threads which are used for decreasing the number of turns of screwing when a deep hole is measured, and a threaded go gauge is formed; two opposite planes are milled on the side face of the shank part, scales used for observing the depth of an inspected threaded hole are printed on one plane, and a tool number, a go and not-go end identification and the specification of the inspected thread are printed on the other plane. According to the composite threaded gauge achieving rapid detection, the multifunctional structural design is adopted, the threaded plug gauge and the threaded depth gauge are integrated on a same inspection tool, thread tooth-type inspection and depth inspection can be achieved simultaneously, the number of inspection tools is decreased, and the tool management cost is reduced. A special structure is adopted by the thread formed in the go end of the inspection tool, the screwing length with the inspected hole can be effectively decreased when the thread depth is detected, rapid measurement of hole depth is achieved, the measurement efficiency is improved, and convenience and rapidness are provided for on-site operation of inspection personnel.

Description

【Technical field】 [0001] The invention belongs to the technical field of detection tools and relates to a rapid detection composite thread gauge. 【Background technique】 [0002] Thread gauges (thread plug gauges and thread depth gauges) are widely used in mass production for their simplicity and reliability. However, it is inconvenient to use different inspection tools for thread profile and depth inspection, and the increase in the number of inspection tools will inevitably bring about increased costs and inconvenience in on-site tooling management. [0003] On the other hand, for thread depth measurement, the traditional method requires the measuring tool to be completely screwed with the entire length of the thread to be measured, which is undoubtedly extremely unfavorable to the work intensity and inspection efficiency of inspectors when faced with a large number of deep hole inspections. 【Content of invention】 [0004] The object of the present invention is to overco...
