Abstract

The utility model discloses a detection tooling of the size of an out-of-round hole of a self-locking nut. The detection tooling consists of an upper limit size measuring body and a lower limit size measuring tool body which are integrally or separately arranged, wherein an upper limit size groove is arranged in the upper limit measuring tool body and is provided with two side walls which are parallel to each other and between which a distance is an upper limit size of the nut to be detected, and a lower limit size groove is arranged in the lower limit measuring tool body and is provided with two side walls which are parallel to each other and between which a distance is a lower limit size of the nut to be detected. According to the detection tooling of the size of the out-of-round hole of the self-locking nut, the out-of-round hole of the self-locking nut is respectively put in the upper limit size groove and the lower limit size groove in an aligning way, and whether the out-of-round hole of the self-locking nut can be put in the grooves or not is judged, so that whether the size of the out-of-round hole of the self-locking nut is larger than the upper and lower limit sizes can be known without reading size data, the detection accuracy is reasonable and the detection speed is quick.

Description

A kind of detection frock of self-locking nut crimping size
Technical field
Whether qualified the utility model relate to a kind of self-locking nut crimping size detection frock that is used to detect.
Background technology
Self-locking nut is shown in Fig. 1-2, owing to possessing good self-locking property, in Aero-Space, the widespread use of defence field.Its relevant criterion all has clearly regulation to the locking property of self-locking nut; Usually for the first time the effective torque that is screwed into, the effective torque after repeatedly (general 5 times, the Aero-Space nut is 15 times) is screwed into, back-outs all should be controlled in the scope of regulation (decay should be too not big).This just requires the closing in size s of self-locking nut to be controlled at a reasonable range.So it is particularly important that the detection of closing in size just seems.Because self-locking nut crimping distortion back be local oval, generally in the prior art adopt manual work with the vernier caliper measurement size that closes up, underproof product is chosen; Reprocess to qualified size; Need be when prior art is used vernier caliper to the taking multiple measurements of the diverse location of the outer peripheral face of self-locking nut, sense data is confirmed the size of self-locking nut; And then judge whether self-locking nut is qualified, make that the efficient of self-locking nut crimping size detection is low.
The utility model content
The purpose of the utility model is to provide a kind of detection frock of self-locking nut crimping size, has solved the inefficient problem of self-locking nut crimping size detection in the prior art.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of detection frock of self-locking nut crimping size; High limit of size measuring and lower limit measuring by one or split setting constitute; Last measuring is provided with high limit of size groove; High limit of size groove have be parallel to each other and spacing be the two side of the nut closing in high limit of size to be measured, following measuring is provided with the lower limit groove, the lower limit groove have be parallel to each other and spacing be the two side of nut closing in lower limit to be measured.
Described upward measuring and following measuring are set to the single measuring of one up and down, and described high limit of size groove and lower limit groove lay respectively at the upper and lower end face of described single measuring.
Described high limit of size groove is a U-lag.
Described lower limit groove is a U-lag.
The detection frock of a kind of self-locking nut crimping size of the utility model; Only need the closing in of self-locking nut be aimed at respectively and put into high limit of size groove and lower limit groove; Judge whether the closing in of self-locking nut can put into wherein; Whether the closing in size that can learn self-locking nut fast surpasses the upper and lower limit size, need not to read dimensional data again, and accuracy of detection is reasonable, detection speed is fast.
Further, last measuring is arranged to one with following measuring, makes things convenient for carrying and using of this detection frock.

Embodiment
A kind of embodiment of detection frock of self-locking nut crimping size; Shown in Fig. 3-4; Comprise by the high limit of size measuring 1 on top and the lower limit measuring 2 of bottom being wholely set the single measuring 11 that constitutes, the upper surface of single measuring 11 is provided with high limit of size groove 12, and high limit of size groove 12 is a U-lag; The two side of the high limit of size groove 12 of U-shaped be parallel to each other and between apart from the high limit of size of dimension D for closing up; Single measuring 11 is provided with lower limit groove 22, and lower limit groove 22 also is a U-lag, the two side of the lower limit groove 22 of U-shaped be parallel to each other and between apart from the lower limit of size d for closing up.
The foregoing description in use; Shown in Fig. 5-8; Aim at the lower limit groove earlier with the closing in position of self-locking nut and put it into, if the self-locking nut crimping position can be smoothly when measuring the lower limit groove of frock, judge this self-locking nut crimping spot size<standard value requirement; The self-locking nut crimping inaccuracy of dimensions, this moment, self-locking nut was for scrapping state; If the closing in position of self-locking nut can't pass the lower limit groove of measuring frock; Again high limit of size groove being aimed at the closing in position of self-locking nut puts it into; If the self-locking nut crimping position can judge that this self-locking nut crimping spot size is qualified smoothly through measuring the high limit of size groove of frock; If this self-locking nut crimping spot size>standard value requirement can not be judged through measuring the high limit of size groove of frock in the self-locking nut crimping position, the self-locking nut crimping inaccuracy of dimensions can guarantee through closing up again this moment.
In other embodiment, described high limit of size measurer and lower limit measurer can also be provided with separately.
