Description

A rapid detection compound thread gauge

【Technical field】

The utility model belongs to the technical field of detection tools and relates to a rapid detection composite thread gauge.

【Background technique】

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.

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 utility model】

The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, provide a kind of rapid detection composite thread gauge that is used for a large number of deep threaded holes.

In order to achieve the above object, the utility model adopts the following technical solutions to achieve:

A rapid detection composite thread gauge, including a handle, the front end of the handle is a through end, the rear end is a stop, and the outside of the stop is provided with threads to form a thread stop gauge; The two sections of thread with the number of turns are enough to form a thread gauge; the side of the shank is milled with two opposite planes, one is printed on the scale for observing the depth of the threaded hole to be inspected, and the other is printed for tooling number, general End-stop identification and thread specifications to be checked.

The further improvement of the utility model is:

The threads of the through end and the stop end are provided with plug gauge chip pockets.

The thread gauge includes an end thread, a middle polished rod and an end thread; the end thread is an incomplete thread profile, which is removed along the circumferential direction by wire cutting and fitter grinding The thread structure makes the radial dimension of the front end smaller than the diameter of the bottom hole of the threaded hole under inspection.

The terminal thread includes a connected front thread and a rear thread, the front thread has the same structure as the end thread of the thread gauge, and the positions of the threaded parts of the two are opposite, and the rear thread is a complete thread.

The polished rod in the middle is a square rod.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model adopts a multi-functional structure design, and integrates the thread plug gauge and the thread depth gauge on the same inspection tool, which can simultaneously realize thread profile detection and depth inspection, reduce the number of inspection tools, and reduce tooling management costs. The thread at the through end of the inspection tool adopts a special structure, which can effectively reduce the screwing length with the measured hole when detecting the thread depth, realize rapid measurement of hole depth, improve measurement efficiency, and provide convenience for inspectors on-site operation.

Further, the overall structure of the utility model is based on the thread plug gauge structure, one end is a thread through gauge, the other end is a thread stop gauge, and the handle has a scale to display the measured thread hole depth value. The structure of the threaded end is special. After the thread processing is completed, part of the structure is removed by wire cutting and fitter grinding. When measuring deep holes, the number of screwing turns is reduced and the depth detection efficiency is improved.

【detailed description】

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1 and Fig. 2, the utility model comprises a handle 3, the front end of the handle 3 is a through end 1, the rear end is a stop end 2, and the outside of the stop end 2 is provided with threads to form a thread stop gauge; the outside of the pass end 1 is provided with The two sections of thread that reduce the number of screwed turns when measuring deep holes are enough to form a thread gauge; the side of the shank 3 is milled with two opposite planes, and a scale for observing the depth of the threaded hole to be inspected is printed on one plane. Another print is for tooling number, no-go identification, and thread size checked. The threads of the through end 1 and the stop end 2 are provided with plug gauge chip pockets 4 . The thread gauge includes the end thread 5, the middle polished rod 6 and the end thread; the end thread 5 is an incomplete thread profile, which is removed along the circumferential direction by wire cutting and fitter grinding The thread structure makes the radial dimension of the front end smaller than the diameter of the bottom hole of the threaded hole under inspection. The terminal thread includes a connected front thread 7 and a rear thread 8. The front thread 7 has the same structure as the end thread 5 of the general thread gauge, and the positions of the threaded parts of the two are relatively arranged, and the rear thread 8 is a complete thread. Middle part polished rod 6 is a square rod.

The thread profile of the non-stop end of the utility model is designed according to the relevant requirements of the thread plug gauge; the handle part is milled with a facet to print the scale, which is used to observe the depth of the threaded hole to be inspected; the small face in the other direction is used to print the tooling number, the mark of the non-stop end and Checked thread specifications, etc.

The rapid depth inspection structure is improved on the basis of the through end of the inspection tool, and the incomplete tooth shape is used, so that the radial dimension of the front end of the inspection tool is smaller than the diameter of the bottom hole of the threaded hole to be inspected, and the inspection tool can be directly inserted into the inspection tool during inspection Threaded holes, eliminating unnecessary screwing, and relying on the complete tooth profile of the end to achieve correct screwing with the measured threaded hole. After the through end is screwed into the bottom of the threaded hole, the depth of the threaded hole can be determined by observing the end face of the hole and the scale of the handle of the inspection tool.

If the through end can be correctly screwed into the threaded hole, it means that the threaded hole under inspection meets the size requirements of the through end of the plug gauge, and the stop end of the inspection tool can be used for further inspection.

As shown in Figure 2, the use process of the inspection tool designed for the M10-7H threaded hole, the structural size of the thread through gauge part, the maximum radial dimension is 7.94, and the diameter of the bottom hole of the thread to be inspected is Φ8.5. During the measurement, the inspection tool can be directly put into the threaded hole to be inspected in the L length section, without screwing in like a conventional depth inspection tool, and the effect is shown in Figure 3.

Working process of the present utility model:

As shown in Figure 4, when the L-length plug gauge completely enters the threaded hole under inspection, the inspection tool can be tilted at a certain angle α (6°~10°), and slowly start to screw together, so that the thread of the inspection tool is in line with the threaded hole under inspection. The threads are initially screwed together. Because the incomplete thread profile and axis of the front and rear sections are symmetrically distributed, there is an automatic correction function during the screw-in process, and the inspection tool will automatically return to the position coincident with the thread axis to be inspected, as shown in Figure 5.

When the inspection tool is completely screwed into the threaded hole to be inspected, the depth dimension of the threaded hole to be inspected can be obtained by visual inspection through the scale printed on the handle of the inspection tool. During the whole process, the inspection tool can be screwed in. It has been shown that the thread profile to be inspected meets the requirements of the through end of the plug gauge, and can be further inspected by the end stop. On the contrary, if the through end of the inspection tool cannot be screwed in no matter how it is adjusted, it means that the checked thread profile is not up to the requirements of the open end, and the thread profile is out of specification, so there is no need to measure the depth dimension.

The above content is only to illustrate the technical idea of the utility model, and cannot limit the protection scope of the utility model. Any changes made on the basis of the technical solution according to the technical idea proposed by the utility model all fall into the scope of the utility model. within the scope of protection of the claims.
