Abstract

The invention belongs to the technical field of measurement instruments and relates to a tool for detecting a threaded hole and an unthreaded hole of a part, in particular to a depth gauge with scales. The depth gauge comprises a go gauge, wherein a measurement sleeve with a scale line and numerical values on the surface is sleeved on the go gauge, the measurement sleeve is in threaded connection with a location ring, a copper sleeve is sleeved between the location ring and the go gauge, a threaded hole is arranged in the location ring, a locking bolt is matched and arranged in the threaded hole, the tail part of the go gauge is fixed on one end of a handle through a first tensioning sleeve, the other end of the handle is fixedly provided with a no-go gauge through a second tensioning sleeve, and an indication groove is etched in the go gauge. The depth gauge is simple, skilled and reasonable in structure, can be used for conveniently and rapidly detecting the threaded hole or unthreaded hole of the part, and can avoid misreading because reading vision of an operator is not influenced.

Description

A kind of band scale depth gauge
Technical field
The invention belongs to the surveying instrument technical field, relate to a kind of instrument that part threaded hole or endoporus are detected, specifically a kind of band scale depth gauge.
Background technology
In machining process, the processing quality of part internal thread (endoporus) directly affects follow-up and fit quality other part, so the crudy of part internal thread (endoporus) is detected the particularly necessity that just seems.Internal thread (endoporus)) mainly contains two detected parameters of thread pitch diameter (diameter of bore) and the degree of depth.At present, detection method commonly used mainly contains: one adopts feeler gauge and slide calliper rule to cooperate detects, and two adopt feeler gauge and carry out qualitative detection at some size grooves of the go side of feeler gauge processing.Though method one energy quantitative measurment, complex operation is measured efficient not high; Method two is measured and drift often can be occurred and be screwed to the end, and the size groove is back to the position of human eye, and the vision or the sense of touch that affects operating personnel are judged, in addition sometimes operating personnel point can't sense of touch, affect the use of the method.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of depth gauge simple in structure, compact, rational is provided, this depth gauge is simple to operate, and detection efficiency is high, energy quantitative measurment, convenient reading etc.
According to technical scheme provided by the invention: a kind of band scale depth gauge, be characterised in that: comprise drift, be set with the surface on the described drift with the measuring unit of scale mark and numerical value, the described measuring unit centring ring that is threaded, be set with copper sheathing between described centring ring and the drift, centring ring is provided with threaded hole, cooperate in the described threaded hole and be provided with lock-screw, described drift afterbody is fixed on handle one end by the first tensioning sleeve, the described handle other end is fixed with no-go gage by the second tensioning sleeve, etching indication groove on the described drift.
As a further improvement on the present invention, first of described drift is measured head and is threaded, and second of described no-go gage is measured head and is threaded.
As a further improvement on the present invention, it is smooth that first of described drift is measured head, and it is smooth that second of described no-go gage is measured head.
As a further improvement on the present invention, described handle is three look handles, and the end that links to each other with drift is for green, and the end that links to each other with no-go gage is for red.
The present invention compared with prior art, advantage is: (1), simple in structure, ingenious, reasonable, can detect quickly and easily the part thread pitch diameter.(2) operating personnel's reading vision is unaffected, avoids misread phenomenon.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A cut-open view among Fig. 1.
Fig. 3 is the smooth depth gauge structural drawing of band scale of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, comprise drift 1, measuring unit 2, indication groove 3, measuring unit end face 4, centring ring 5, handle 6, no-go gage 7, lock-screw 8, threaded hole 9, copper sheathing 10, the first tensioning sleeve 11, the second tensioning sleeve 12, the first measurement head 13, the second measurement head 14 etc.
As shown in Figure 1 and Figure 2, the present invention is a kind of depth gauge, comprise drift 1, be set with the surface on the described drift 1 with the measuring unit 2 of scale mark and numerical value, described measuring unit 2 centring ring 5 that is threaded, be set with copper sheathing 10 between described centring ring 5 and the drift 1, centring ring 5 is provided with threaded hole 9, described threaded hole 9 interior cooperations are provided with lock-screw 8, described drift 1 afterbody is fixed on handle 6 one ends by the first tensioning sleeve 11, described handle 6 other ends are fixed with no-go gage 7 by the second tensioning sleeve 12, etching indication groove 3 on the described drift 1.
First of described drift 1 is measured head 13 and is threaded, and second of described no-go gage 7 is measured head 14 and is threaded.
Described handle 6 is three look handles, and the end that links to each other with drift 1 is for green, and the end that links to each other with no-go gage 7 is for red.
The course of work of the present invention is as follows: drift 1 and no-go gage 7 detect the specification of thread pitch diameter, drift 1 screws in measured internal thread bottom during measurement, lock-screw 8 unclamps, measuring unit 2, centring ring 5 and copper sheathing 10 slide together, the end face 4 of measuring unit 2 contacts with measured internal thread end face, and the indication groove 3 on the screw thread drift 1 and scale mark and the numerical value institute respective value on the measuring unit 2 are exactly the degree of depth of measured internal thread at this moment.Inconvenient or can't reading such as the detection position, after lock-screw 8 lockings, reading after screwing out again.
The present invention is simple in structure, ingenious, reasonable, can detect quickly and easily the part internal thread, and operating personnel's reading vision is unaffected, avoids misread phenomenon.
Be with the smooth depth gauge structure of scale as shown in Figure 3, its measuring principle is identical with band scale depth of thread rule with method of operating.
