Description

Go-no go gauge pattern depth of thread gauge

Technical field

The utility model is related to a kind of special measuring tools for detecting the machined depth of thread.

Background technology

There are high-volume same size and the threaded hole of depth in engine component process, to reach guarantee product The targets such as quality and the cost of charp tool need frequently to measure the size of screw thread hole depth.

In existing industry, it is common to use thread quality gauge cooperation vernier caliper measures, and also fraction uses band The depth of thread of scale or digital display class is advised（Similar to slide calliper rule）.The former needs first to read the length of external thread gauge in process variable is surveyed Degree, then screws in machined screw thread, then obtain the depth of thread by dimension conversion by external thread gauge.Due to being calculated, It is relatively high to the level of skill requirement of survey crew, while measurement process is very cumbersome, measurement efficiency is very low.Although and the latter Precision is high, but its higher price and is easily damaged, and there is still a need for readings, are more suitable for the fields such as research and development of products.Two kinds of surveys Amount method is applied when in there are the batch production process of a large amount of threaded holes, the efficiency that meeting extreme influence measures.

Invention content

In order to overcome the above problem existing for existing method, the utility model provides a kind of go-no go gauge pattern depth of thread Gauge.The gauge is suitable for metastable high volume production process to size, the identical threaded hole that need to frequently measure of specification Depth carries out quality verification, at low cost with easy to operate, simple in structure, manufacture and durable etc. advantages, and can improve survey Amount efficiency makes operator have more times to do other work.

The purpose of this utility model is achieved through the following technical solutions：

A kind of go-no go gauge pattern depth of thread gauge, including screw thread length bar and screw thread length bar sleeve, wherein：

The left end of the screw thread length bar is equipped with go-no go gauge, and right end is equipped with oblong openings；

The screw thread length bar sleeve is equipped with and the corresponding screw thread mouth of oblong openings；

The right end of the screw thread length bar by oblong openings and screw thread mouth it is axially adjustable be connected to screw thread length bar sleeve It is interior.

Threaded hole is measured to bottom in use, the screw thread length bar with go-no go gauge is screwed in, and passes through full-length Screw thread length bar sleeve to the depth of thread, whether verify by qualification.

The utility model has the following advantages：

The go-no go gauge pattern depth of thread gauge of the utility model is a kind of and compact measurement apparatus of produce reality, It is a kind of measuring instrument efficiently, inexpensive, is suitable for threaded hole identical to a large amount of specifications in batch production and surveys Amount.By reduction using calliper and the process calculated, time of measuring is saved, labor intensity is reduced and calculates the measurement brought The risk of mistake, can greatly improve the measurement efficiency of reviewer and operator, and reduce labor intensity.

Specific embodiment

The technical solution of the utility model is further described below in conjunction with the accompanying drawings, however, it is not limited to this, every Technical solutions of the utility model are modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model It encloses, should all cover in the scope of protection of the utility model.

As shown in Figs 1-4, go-no go gauge pattern depth of thread gauge provided by the utility model is by screw thread length bar 1, amount of thread Stick sleeve 2, fastening bolt 3 form, wherein：

The left end band go-no go gauge of the screw thread length bar 1, right end are equipped with oblong openings；

The screw thread length bar sleeve 2 is equipped with and the corresponding screw thread mouth of oblong openings；

The right end of the screw thread length bar 1 is axially adjustable in screw thread length bar sleeve 2 by oblong openings and screw thread mouth；

The fastening bolt 3 passes through screw thread mouth and oblong openings that screw thread length bar 1 and screw thread length bar sleeve 2 are connected as one Body.

The go-no go gauge device of the utility model can quickly carry out depth of thread verification, as shown in figure 5, using process such as Under：

（a）Go-no go gauge screw thread length bar part is screwed in and is measured threaded hole to the bottom of thread.

（b）Whether qualified carry out verification product to go-no go gauge position with tactile by visual observation.

By taking M10 screw thread hole depths as an example：Each measurement process total time-consuming 4 minutes, wherein screwing and screw out external thread gauge needs Take about 1 minute.The length for exposing workpiece surface after quality gauge to the length of thread quality gauge and screwing measures Then reading carries out dimension conversion, average to take about 3 minutes.Use the go-no go gauge pattern depth of thread gauge of the utility model The time of reading and dimension conversion can be eliminated, it is only necessary to screw in screw thread, screw out screw thread can to the depth of thread it is whether qualified into Row verification, can improve 4 times of measurement efficiency.

Claims (1)

1. a kind of go-no go gauge pattern depth of thread gauge, it is characterised in that the depth of thread gauge is by screw thread length bar and amount of thread Stick sleeve forms, wherein：
