Abstract
The invention discloses a kind of strong magnet rotor length detection snap-gauge, including a body, the body to be equipped with measuring flume, and the side and bottom surface of the measuring flume are perpendicular；Body is made of non-magnet material.The present invention can be disturbed to avoid by strong magnetic attachment, more quickly and accurately draw measurement result, and cost is relatively low.
Description
Technical field：
The present invention relates to a kind of strong magnet rotor length detection snap-gauge.
Background technology：
Because the rotor in magnetic suspension motor has strong magnetic, the making material of traditional vernier caliper or micrometer existing in the market
Material is permeability magnetic material (specific customization measurer cost is too high), can all be held by this kind of rotor, cause inconvenient measurement.Force to use
Common calliper needs more people to coordinate when detecting, and be easy to cause rotor surface damage and damage slide calliper rule；Other are such as rubber ruler
Measurement accuracy requirement is not reached Deng measurer.Therefore, it is necessory to be improved to the prior art to solve the deficiency of the prior art.
The content of the invention：
The present invention is to provide a kind of strong magnet rotor length detection snap-gauge to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：A kind of strong magnet rotor length detection snap-gauge, including a body, the body
Measuring flume is equipped with, the side and bottom surface of the measuring flume are perpendicular；
Body is made of non-magnet material.
Further, the body is equipped with lightening hole.
The present invention has the advantages that：The present invention can be disturbed to avoid by strong magnetic attachment, more quickly and accurately
Go out measurement result, cost is relatively low.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 is application structure figure of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
Such as Fig. 1, the present invention discloses a kind of strong magnet rotor length detection snap-gauge, including a body 1, is equipped with and surveys on body 1
Measuring tank 11, the side and bottom surface of the measuring flume 11 are perpendicular.Body 1 is made of non-magnet material.
To mitigate weight, lightening hole 12 is equipped with body 1.
In application, make the snap-gauge of some suitable dimensions, for example, rotor size to be measured and tolerance for 607 (0~+
0.2), 11 length of snap-gauge measuring flume of making is for 607.5 (specific size be subject to measured value).
Such as Fig. 2, in use, by one detection faces of snap-gauge fitting rotor, one size end face, another detection faces are the same as rotor other one
The gap of 0.5mm or so is formed between size end face, detects the gap actual size using standard clearance gauge at this time, final rotor
Physical length subtracts clearance gauge thickness for snap-gauge measured value.
To ensure the accuracy of testing result, following work is carried out：
1) snap-gauge opening spacing is detected using the preceding slide calliper rule with reference block or qualification every time, record is actual
Value；
2) used and lain in snap-gauge in special box, and placed according to the environmental condition required by measurer, prevented
Only deform.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made without departing from the principle of the present invention, these improvement also should be regarded as the present invention's
Protection domain.
