[0002] The motor stator includes a stator core and windings. The inner circumference of the stator core is provided with several winding slots. The windings are fitted with the winding slots. The part between two adjacent winding slots is the yoke. The outer circumference of the stator core is provided with grooves.

[0004] Currently, the only way to measure the position of the groove is by using a projector or coordinate measuring machine. Although this method can accurately measure the position of the groove, it requires specialized equipment and measurement personnel with relevant measurement knowledge.

[0033] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art are briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other embodiments can be obtained based on the drawings without creative effort, and these embodiments are still within the protection scope of the claims of this utility model.

[0034] like Figures 1 to 5 This utility model discloses a detection mechanism for the groove position of a stator core, comprising a base 1, a support 2, a sliding support 3, a measuring cone 4, a gauge support 5, and a measuring gauge 6. The following is a detailed description of each part and the relationship between them.

[0035] The base 1 is generally rectangular or cubic. The base 1 consists of a base plate 1a and a boss 1b located on the base plate 1a. A notch 1c is formed between the base plate 1a and the boss 1b. After the support 2 is engaged with the notch 1c, the support 2 is fixed to the base 1.

[0036] Support 2 is fixed to base plate 1a. Support 2 includes fixed seat 2a, slide rail 2b for sliding cooperation with sliding seat 3, and support body 2c. Fixed seat 2a is fixed to base 1.

The slide body 3a has a sliding groove for sliding engagement with the support 2. The mounting base 3b is fixed to the support 2 and has a guide hole 3c for clearance engagement with the measuring cone 4. The guide hole 3c is a stepped hole. When a force is applied to the sliding mount 3 along the X-axis of the base 1, the sliding mount 3 can move along the X-axis of the base 1.

[0038] The measuring cone 4 is used for insertion and mating with the groove. The measuring cone 4 is arranged along the Y-axis of the base 1 and has a clearance fit with the sliding seat 3. The measuring cone 4 includes a cone body 4a and a push-pull handle 4b. One end of the cone body 4a is fixed to the push-pull handle 4b, and a limiting protrusion 4c is provided on the circumferential surface of the cone body 4a or the push-pull handle 4b. In this embodiment, the cone body 4a has a clearance fit with the small-diameter section and the large-diameter section of the guide hole 3c, the push-pull handle 4b has a clearance fit with the large-diameter section of the guide hole 3c, and the limiting protrusion 4c is located in the large-diameter section of the guide hole 3c and has a clearance fit with the large-diameter section. When the measuring cone 4 feeds into the groove, if the limiting protrusion 4c and the step in the guide hole 3c cannot move, the feed amount of the measuring cone 4 reaches its maximum.

[0039] The gauge support 5 is connected to the support 2 or the base 1. The measuring instrument 6 abuts against the sliding seat 3. In this embodiment, the gauge support 5 is preferably fixed to the support body 2c in the support 2. The support body 2c has a through hole, and the measuring instrument 6 passes through the gauge support 5 and the support body 2c before abutting against the sliding seat 3. The measuring instrument 6 is a dial indicator or a micrometer indicator.

[0040] The standard component mates with the base 1. The standard component has a standard groove 8a on its circumferential surface for mates with the measuring cone 4. The standard component includes a connecting seat 7 and a standard block 8. The connecting seat 7 mates with the base 1 and is annular. The connecting seat 7 has a groove 7a. The standard block 8 mates with the groove and is fixed to the connecting seat 7. The standard groove 8a is located on the standard block 8. The connecting seat 7 also has a slot 7b or insertion hole for the positioning component to be inserted into. The slot 7b or insertion hole communicates with the groove 7a. The standard block 8 has an extension 8b that mates with the slot 7b or insertion hole.

[0041] The positioning component positions the standard component and is fixed to the base 1. The positioning component includes a positioning seat 9 and a connecting block 10. The positioning seat 9 is connected to the base 1. The boss 1b is provided with an assembly groove, and the positioning seat 9 is provided with a protrusion. After the protrusion mates with the assembly groove, the positioning seat 9 and the boss 1b are fastened together as a whole by screws.

[0042] The connecting block 10 is connected to the base 1 or the positioning seat 9. In this embodiment, the positioning seat 9 is provided with a clearance groove 9a, and the connecting block 10 is clearance-fitted with the clearance groove 9a. The bottom of the mounting groove on the boss 1b is provided with a mounting hole 1d. A screw is used to pass through the connecting block 10 and engage with the mounting hole on the boss 1b, thereby positioning the connecting block 10. At least two positioning blocks 11 are provided on the circumferential surface of the connecting block 10, and a mating groove 12 is formed between two adjacent positioning blocks 11 to engage with a standard component or stator core.

[0043] This utility model also includes a clamping assembly for clamping standard components or stator cores. There are at least two clamping assemblies. Each clamping assembly includes a clamping block 13 and a screw 14. A threaded hole is provided on the side of the base 1. The screw 14 passes through the clamping block 13 and is threadedly connected to the threaded hole on the base 1.

[0044] This utility model also includes a support rod 15, which is fixed to the base 1. An angle of 20-70° is formed between the base 1 and the support rod 15, preferably 50°. With this structure, the ends of the base 1 and the support rod 15 can be fitted with the worktable (not shown in the worktable figure), thereby forming a triangular structure between the base 1, the support rod 15, and the worktable. When the stator core A is placed on the base 1, the stator core A can automatically abut against the positioning seat 9 under the action of gravity, which helps to save operation time.

[0045] The usage process of this utility model is as follows:

[0046] like Figures 1 to 5 First, surround the connecting seat 7 around the positioning seat 9, ensuring the inner wall of the connecting seat 7 abuts against the positioning seat 9. After aligning the standard block 8 with the groove 7a on the connecting seat 7, insert the extension 8b of the standard block 8 into the mating groove 12, and secure the standard block 8 to the connecting seat 7 with screws. Apply a pushing force to the push-pull handle 4b, causing the cone 4a to insert into the standard groove 8a. Adjust the measuring gauge 6 until its reading is zero. This completes the calibration and zeroing of the measuring gauge 6 using the standard assembly.

[0047] Remove the connector 7 with the standard block 8 from the base 1, and place the stator core A to be tested on the base 1. Figure 6 The inner wall of the stator core A is brought abutted against the positioning seat 9, and the groove B on the outer circumferential surface of the stator core A aligns with the cone 4a. At this time, one of the yokes C is inserted into the mating groove 12 and fits with the mating groove 12 with a clearance. The screw 14 is tightened, and the stator core A is clamped by the clamping block 13, thereby fixing the stator core A and preventing it from moving. A pushing force is applied to the push-pull handle 4b, causing the cone 4a to be inserted into the groove B on the outer circumferential surface of the stator core A. A force is applied to the sliding mount 3 along the X-axis of the base 1, causing the sliding mount 3 to move the measuring cone 4 along the X-axis of the base 1. Since the measuring gauge 6 is against the sliding mount 3, if the measuring cone 4 inserted in the groove B can move, the reading on the measuring gauge 6 will change. The reading is obtained from the measuring gauge 6 and 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 machined groove B meets the requirements; if it does not, it means that the machined groove B does not meet the requirements.
