Miscellaneous, field test personnel can not quickly detect, and need three coordinate measurements of professional, and process is complicated, and round of visits is long to ask
Topic.
In order to achieve the above objectives, the utility model adopts the following technical solution: a kind of permanent magnetism vector motor stator piece inspection
Tooling is tested, including the fixed disc for placing stator piece and the inner diameter check tool and outer diameter that are used cooperatively with fixed disc
Cubing, fixed disc middle part is axial to offer inner diameter measurement hole, and one end face edge of fixed disc is circumferentially evenly arranged with several axis
It is described interior relative to the symmetrical spacer pin of the positioning pin there are two settings on the inside of one of positioning pin to the positioning pin in direction
Diameter cubing includes internal diameter drift, internal diameter no-go gage, and the testing fixture for external diameter includes outer diameter drift, outer diameter no-go gage.
Further, internal diameter drift one end is central axial is provided with fixing axle, and internal diameter no-go gage one end is provided with handle, another
Hold it is central axial offer fixation hole, fixing axle and fixation hole are cooperatively connected.
Further, the fixing axle is threadedly coupled with fixation hole.
Further, on internal diameter no-go gage fixation hole be provided with No.1 chamfering between end face at one end and lateral surface.
Further, the outer diameter drift and outer diameter no-go gage integral structure.
Further, outer diameter drift and outer diameter no-go gage inner sidewall connection are provided with No. two chamferings.
Further, testing fixture for external diameter further includes median drift.
The utility model has the beneficial effect that compared with prior art
1. can quickly judge whether the stator of permanent magnetism vector motor is qualified, does not have to measure specific data, quickly inspect by random samples,
The size of intuitive judgment product improves the efficiency of production testing；
2. internal diameter drift is fixed in the fixation hole of internal diameter no-go gage by fixing axle, is fixed, detected using coaxial
When, can show whether internal diameter is qualified with one-time detection, internal diameter drift need to be only inserted into stator by detection method simple, intuitive
Diameter, if internal diameter no-go gage cannot be inserted into, internal diameter drift be can be inserted, then proves internal diameter qualification, on the contrary then stator is unqualified；By outer diameter
No-go gage and outer diameter drift are integrally formed, and are coaxially disposed, and detection is facilitated, and cover outer diameter drift on stator when need to only detect, if
Outer diameter no-go gage cannot be set on stator, and outer diameter drift can be set on stator, then prove stator outer diameter qualification, on the contrary then fixed
Son is unqualified；The No.1 chamfering opened up on internal diameter no-go gage facilitates detection, prevents because internal diameter no-go gage is different from internal diameter drift diameter
And stop, the abnormal situation of detection occur occurs, and outer diameter no-go gage and outer diameter drift can be prevented by similarly offering No. two chamferings
Diameter it is different and stops, the abnormal situation generation of detection occur while can also be improved detection efficiency.
