Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example

[0024] like Figures 1-2 As shown, this embodiment provides a core straightening fixture, including a support assembly 1 for supporting the stator, a fixture fixing plate 5 on the top of the support assembly 1, and a straightening assembly 2 for compressing and straightening the outer periphery of the stator mounted on the fixture fixing plate 5. Details are as follows... Figure 4 and 6 As shown, the straightening assembly 2 includes two symmetrical mounting strips 201 fixed to both sides of the tooling fixing plate 5. Two sliding rods 202 are fixed between the two mounting strips 201. Two symmetrical sliders 203 are slidably fitted onto the two sliding rods 202, allowing the sliders 203 to slide back and forth at the two sliding rods 202. A screw 204 is threaded to the middle portion of each of the two mounting strips 201. A rotating shaft 205 is fixedly connected to the end of the screw 204 near the slider 203. A rotating shaft 205 is fixedly installed on the side of the slider 203 near the adjacent mounting strip 201. The snap-fit ​​block 206 has an upward-facing U-shaped slot 210. The rotating shaft 205 is placed in the U-shaped slot 210. When the screw 204 is rotated by the added handle 209, the rotating shaft 205 rotates in the U-shaped slot 210, so as to realize the purpose of adjusting the slider 203 to slide back and forth along the slide bar 202. Each slider 203 has a mounting base 207 installed at the two inner corners. Each mounting base 207 has a vertically set roller 208 installed at it to adapt to the fit of the outer ring when the stator rotates.

[0025] like Figure 3 As shown, the support assembly 1 includes a tray 101 with an opening in the middle. An inner support cylinder 102 is fixed at the opening. A fixed cylinder 103 concentric with the inner support cylinder 102 is also fixed in the middle of the tray 101. A limiting block 104 is fixed on the outer peripheral wall of the inner support cylinder 102 for matching the vertical groove on the outer periphery of the stator (i.e., the vertical groove on the outer surface of the conventional stator). The end of the limiting block 104 extends into the interior of the inner support cylinder 102.

[0026] like Figure 4As shown, the correction component 2 is provided with a caliper component 3 for easy and precise adjustment. In detail, the caliper component 3 includes two clamping blocks 301. The two clamping blocks 301 are fixedly installed on any slide bar 202. The fixed installation position is determined according to the actual stator specifications and can be evenly distributed at both ends of the center of the slide bar 202. Two aligning members 302 are fixedly installed on the two clamping blocks 301. Calipers 303 that cooperate with the aligning members 302 are fixedly installed on the upper surface of the two sliders 203 near the clamping blocks 301 respectively.

[0027] The tooling fixing plate 5 has a through groove 6 in the middle for the stator to pass through. The tooling fixing plate 5 is equipped with several roller assemblies 4 that are adapted to the through groove 6. Specifically, the roller assembly 4 includes six fixing bolts 401. Two fixing bolts 401 are provided through the tooling fixing plate 5 on the side near the slide rod 202. The bottom of the fixing bolt 401 is rotatably mounted with a roller 402. The upper end of the fixing bolt 401 is threadedly connected with a fixing nut 403 for limiting the position. The roller 402 is placed on the outer periphery of the fixing cylinder 103 and contacts the outer periphery of the fixing cylinder 103, which facilitates the rotation of the tooling.

[0028] like Figures 5-6 As shown, it should be noted that the bottom of the middle of the other two sliders 203 is also fixed with connecting blocks 7, and the connecting blocks 7 are equipped with two other fixing bolts 401 as well as rollers 402 and fixing nuts 403 installed in the same manner as above. Their function is to make the rotation of the fixed cylinder 103 smoother by increasing the number of rollers 402.

[0029] In this embodiment, the core straightening fixture first places the stator onto the inner support cylinder 102 on the tray 101, so that any vertical groove on the outer periphery of the stator is aligned with the end of the limiting block 104. Figure 2 The vertical grooves on the surface of the stator are called vertical grooves (corresponding to the end of the limiting block 104). At the same time, the through groove 6 at the bottom of the tooling fixing plate 5 is placed on the fixing cylinder 103, so that the stator passes through the through groove 6 and is located between the two straightening components 2. After the overall tooling is placed, one of the straightening components 2 is adjusted first. The screw 204 is rotated by the handle 209, which pushes the slider 203 to move along the slide bar 202 towards the stator. When the alignment part 302 is aligned with the position set on the caliper 303, the handle 209 is no longer rotated. Then the other handle 209 is rotated so that the other alignment part 302 is aligned with the position set on the caliper 303. Then the tooling is rotated, and the outer periphery of the stator is squeezed and straightened by the roller 208.

[0030] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
