[0004] The existing method of measuring the groove position can only be done using a projector or a three-coordinate measuring machine. Although this method can accurately measure the groove position, it requires special equipment and measurement personnel with relevant measurement knowledge to perform the measurement. Generally, operators cannot measure whether the groove position meets the design tolerance on the drawing alone. Summary of the invention

The fixed seat is fixed to the base, the slide rail is fixed to the fixed seat, the support body is fixed to the fixed seat, and the meter support is fixed to the support body.

[0008] Furthermore, the sliding seat includes a sliding seat body and a mounting seat. The sliding seat body is provided with a sliding groove for slidingly matching with the support. The mounting seat is fixed to the support. The mounting seat is provided with a guide hole for matching with the measuring cone gap. The guide hole is a step hole.

[0009] Furthermore, the measuring cone includes a cone body and a push-pull handle. One end of the cone body is fixed to the push-pull handle. A limiting protrusion is provided on the circumferential surface of the cone body or the push-pull handle.

[0010] Furthermore, the standard component includes a connecting seat and a standard block. The connecting seat cooperates with the base, and a groove is provided on the connecting seat. The standard block is connected to the connecting seat after cooperating with the groove. The standard groove is set on the standard block, and the connecting seat is also provided with a slot or a socket for plugging and cooperating with the positioning component, and the slot or the socket is connected with the groove.

[0011] Furthermore, the connecting seat is annular, and the standard block is provided with an extension portion, which cooperates with the slot or the jack.

[0012] Furthermore, the positioning assembly includes a positioning seat and a connecting block. The positioning seat is fixed to the base, and the connecting block is fixed to the base or the positioning seat.

At this time, one of the yokes is inserted into the coupling groove and is gap-matched with the coupling groove 12. The screws are tightened, and the stator core is clamped by the clamp block, so that the stator core is fixed to prevent the stator core from moving. A thrust is applied to the push-pull handle to insert the cone into the groove on the outer peripheral surface of the stator core. A force is applied to the sliding seat along the axial direction of the base, so that the sliding seat drives the measuring cone to move along the axial direction of the base. Since the measuring table abuts against the sliding seat, if the measuring cone inserted in the groove can move, the reading on the measuring table changes, and the reading is obtained from the measuring table. The reading is compared with the design value on the drawing to determine whether the reading falls within the tolerance range required on the drawing. If it does, it means that the processed groove meets the requirements; if not, it means that the processed groove does not meet the requirements.

[0016] The present invention drives the measuring cone inserted into the groove to move linearly through the sliding seat, so that the reading of the measuring meter changes. This structure can detect stators of different models, which can save a lot of time for confirming the groove position, and also improves the accuracy of measurement, making the existing measurement values ​​more accurate and reliable.

Apply a thrust to the push-pull handle 4b, so that the cone 4a is inserted into the groove B on the outer circumference of the stator core A. Apply a force along the X-axis direction of the base 1 to the sliding seat 3, so that the sliding seat 3 drives the measuring cone 4 to move along the X-axis direction of the base 1. Since the measuring table 6 is against the sliding seat 3, if the measuring cone 4 inserted in the groove B can move, the reading on the measuring table 6 will change. The reading is obtained from the measuring table 6, and the reading is compared with the design value on the drawing to determine whether the reading falls within the tolerance range required on the drawing. If so, it means that the processed groove B meets the requirements; if not, it means that the processed groove B does not meet the requirements.
