Abstract

Split type smooth internal limit gage for stopper is processed to internal grinding machine and lathe, and the stopper feeler gauge includes go side and not -go -end all have gauge head, handle, round pin, and its characterized in that carves a groove at the go side handle, and every 10mm is the interval and has on the gauge head neck being greater than radial outstanding screw, is used for the blind hole bottom that gets into whole prior to the gauge head. This frock precision high (IT6 level and more than), be applicable to the internal diameter in the detection of 100~315mm blind hole part, be applicable to the ordinary part that the internal diameter is 100~315mm too, it is still scaled that the handle of advising is led to in this design, it is clear and definite, the degree of depth in suggestion hole directly perceived, can more audio -visual resolution lead to rule, the no -go gage, detection length has been increased, provide swift measurement mode for the operator, improve work efficiency, avoid because the too big go side of empty sword blocks after going down, the condition that is difficult for taking out takes place, in a disguised form improve feeler gauge life. Feeler gauge simple structure, low in manufacturing cost, materials are few, and remaining material also can recycle.

Description

A kind of split type smooth internal limit gage

Technical field

This utility model relates to plant equipment and manufactures field, is specifically related to a kind of feeler gauge carrying out surveying plug to aperture。

Background technology

Smooth feeler gauge is a kind of accurate plug tool for surveying plug workpiece smooth inner bore size, and bright finish feeler gauge makes maximum limit of size and the minimum limit of size two kinds, with the use of。In a set of plug tool, the measuring head diameter minimum limit of size is called go side, and gauge head maximum limit of size is called not-go-end, and in surveying plug, go side feeler gauge should pass through inner hole of workpiece path, and its no-go end feeler gage then should not pass through this path。

In current GB1957-2006 " smooth internal limit gage ", inner hole of workpiece footpath size detection being used smooth feeler gauge, the smooth feeler gauge of known split comprises drift, no-go gage [actually general call " go side=drift gauge head " " not-go-end=no-go gage gauge head "。Whether entering the situation in workpiece hole by logical, the not-go-end of feeler gauge, to judge to change aperture qualified, go side enter and not-go-end be judged to when can not enter qualified。The feeler gauge pattern recommended according to national standard and range of application table thereof, do not specify not holotype feeler gauge specifically why shape, only indicate that internal diameter can make not holotype (part for cylinder) between the feeler gauge of 100mm～315mm。The phenomenon of this kind of feeler gauge existing defects is: when detection is relatively big-diameter blind hole, when there is again wider empty cutter on its side, the go side of feeler gauge is stuck when being likely to down bottom, even if taking out, will also result in a degree of abrasion of workpiece。

Summary of the invention

The purpose of this utility model is in that to provide a kind of split type smooth internal limit gage, overcomes disadvantages mentioned above, feeler gauge go side can be prevented to be stuck, and feeler gauge go side can rapidly enter blind hole and can correctly detect blind hole plug。

A kind of split type smooth internal limit gage, for internal grinder and lathe process, a set of feeler gauge includes go side and not-go-end, structure is identical: the pin-and-hole at straight pin traverse handle and gauge head central link place, it is characterized in that carving a groove on the handle of go side, every 10mm is interval and has radially projecting screw on gauge head cervical region, for entering blind via bottom prior to gauge head entirety。

This utility model has the advantage that this tool structure is simple, precision high (IT6 level and more than), efficiency is high, low cost of manufacture, suitable in internal diameter in the detection of 100～315mm blind-hole parts, it is applied equally to the common parts that internal diameter is 100～315mm, it is possible to differentiate drift, no-go gage more intuitively。Blocking after can also avoiding down due to the empty excessive go side of cutter, situation about not easily taking out occurs；Gauge head cervical region has and highlights screw radially, for entering blind via bottom prior to gauge head entirety, add detection length, and avoid gauge head to be stuck, in a disguised form raising feeler gauge service life。Owing to go side, not-go-end materials are saved, remaining material can also be recycled。The handle of the design drift also has scale, clearly, the degree of depth in visual cues hole, provides quick metering system to operator。

Detailed description of the invention

The split type smooth internal limit gage of this utility model, during for internal grinder and lathe process, detection is between 100～315mm blind-hole parts, the feeler gauge pattern recommended according to national standard and range of application table thereof, a set of feeler gauge includes go side and not-go-end, see Fig. 8 a～d, for the not holotype that structure is identical: straight pin 3 is through the pin-and-hole of handle 2 with gauge head 1 central link place, see accompanying drawing 2～7, it is characterized in that at go side handle 2 groove at quarter one, every 10mm is interval and has radially projecting screw on gauge head 1 cervical region, for entering blind via bottom prior to gauge head entirety。Split type smooth slip limit plug feeler gauge, for the detection to part aperture, structure is identical: straight pin 3,3 ' is passed through the pin-and-hole of handle 2,2 ' styletable and gauge head 1,1 ' junction, it is characterized in that: carve a groove at go side handle 2 axial plane, every 10mm is interval and has radially projecting screw 4 on gauge head 1 cervical region, for entering blind via bottom prior to gauge head entirety。

Holotype go side gauge head 1, not-go-end gauge head 1 ' are not cylinder and cut both sides, only retain diameter and 10 °～20 ° parts of both sides radian thereof, and by the center of circle to antermarginal straight line constriction, circle centre position has radial hole, dispose handle 2,2 ' styletable and have axial aperture, disposing straight pin 3；Go side gauge head 1 and not-go-end gauge head 1 ' distinguishing characteristics are that go side gauge head 1 has a radial screw hole with side edge straight line place。

Go side handle 2 axially cuts one section of radian, forms plane, is carved with groove。

Screw 4 length through gauge head 1 screw hole to be longer than gauge head 1 radial width。

Use this set feeler gauge of the design, first the length of workpiece blind hole is obtained according to drawing or survey plug handle scale estimation, length according to workpiece blind hole deduces feeler gauge go side and enters into the position of blind hole end, it is screwed into corresponding screw, or make marks in the position of drift handle, remember the position near this labelling, with the naked eye estimate that it is with using Position Approximate, or it is stuck in part outer end of hole with flat parts such as clearance gauges, convenient location。So can relieved, fast use drift, withstand on inner bore of part until screw one is surveyed。
