[0035] The embodiments of the utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the utility model are described in detail below. Figures 1-5 The clamp device 100 of the stator according to the embodiment of the utility model is described below.

[0036] The embodiments of the utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the utility model are described in detail below. Figures 1-3As shown, the stator clamp device 100 of the utility model embodiment, including: base 10 and clamping assembly 20, clamping assembly 20 set up at base 10, clamping assembly 20 includes: first clamping piece 21 and multiple second clamping pieces 22, first clamping piece 21 can rotatably be provided at base 10, multiple second clamping pieces 22 are respectively provided at first clamping piece 21, and multiple second clamping pieces 22 respectively form the accommodation cavity 30 of clamping stator with first clamping piece 21.

[0037] Specifically, the stator clamp device 100 is mainly composed of base 10 and clamping assembly 20, and the base 10 can provide the mounting position for the clamping assembly 20 and can provide the supporting force for the clamping assembly 20.

[0038] Among them, clamping assembly 20 is mainly composed of first clamping piece 21 and multiple second clamping pieces 22, first clamping piece 21 can rotatably be provided at base 10, since first clamping piece 21 and multiple second clamping pieces 22 are connected and matched, when first clamping piece 21 rotates, the whole clamping assembly 20 can rotate. When the stator core with winding in the clamping assembly 20 needs to be dipped in paint, after the stator core in the clamping assembly 20 is dipped in paint in the paint tank for one side, the stator core can be turned over by 180° by rotating first clamping piece 21, and the other side of the stator core can be dipped in paint, so that double-sided dipping in paint of the stator core can be realized, and the whole stator core can be dipped in paint without dead angle.

[0039] Similarly, when the stator core with winding in the clamping assembly 20 needs to be baked, one side of the stator core in the clamping assembly 20 can face the air outlet of the baking oven, and when one side of the stator core is baked, the stator core can be turned over by rotating first clamping piece 21.

[0040] In addition, multiple second clamping pieces 22 respectively form the accommodation cavity 30 of clamping stator with first clamping piece 21, wherein the accommodation cavity 30 is multiple, and multiple second clamping pieces 22 and first clamping piece 21 can jointly clamp multiple stator cores with winding, since the stator core with winding is heavy, the stator core with winding is placed in the accommodation cavity 30, so that the multiple stator cores with winding can be conveniently turned over.

[0041] Moreover, multiple stator cores with winding on the clamp device 100 can achieve maximum utilization in the limited volume of the dipping equipment and the baking oven, so that the dipping and baking efficiency of the multiple stator cores with winding can be improved, and the clamp device 100 can be conveniently moved between the dipping and the oven, and after the dipping and baking are completed, the support effect of the clamp device 100 can also facilitate the varnish operation and the insulation voltage detection work.

[0042] Therefore, the clamp device 100 of the stator can facilitate the overturning of the plurality of band-winding stator cores, thereby improving the impregnation and baking efficiency of the plurality of band-winding stator cores.

[0043] According to some embodiments of the present application, as shown in Figure 1 The plurality of second clamping pieces 22 are respectively arranged on the two sides of the first clamping piece 21, and the second clamping piece 22 on each side forms a containing cavity 30 with the first clamping piece 21.

Moreover, the second clamping piece 22 on each side forms a containing cavity 30 with the first clamping piece 21, so that the plurality of second clamping pieces 22 and the first clamping piece 21 can form a plurality of containing cavities 30, and each containing cavity 30 can place a band-winding stator core, thereby increasing the number of clamped band-winding stator cores.

[0045] According to some embodiments of the present application, as shown in Figure 1 The second clamping piece 22 on each side forms a plurality of containing cavities 30 arranged along the length direction of the first clamping piece 21 with the first clamping piece 21.

[0046] Specifically, the plurality of containing cavities 30 arranged along the length direction of the first clamping piece 21 can clamp a plurality of stator cores, and the length direction is the left-right direction, thereby avoiding clamping a single stator core. Moreover, the plurality of containing cavities 30 arranged along the length direction of the first clamping piece 21 are arranged at intervals, and the length direction is the left-right direction, thereby avoiding interference between the stator cores in the adjacent two containing cavities 30.

[0048] The first clamping groove 40 and the second clamping groove 50 can jointly exert force on the stator core, and can limit the stator core, thereby preventing the stator core from moving in the containing cavity 30, and also improving the stability of clamping the stator core.

[0049] According to some embodiments of the present application, as shown in Figure 1As shown, the clamping assembly 20 further comprises an adjusting member 60, which is arranged between the first clamping member 21 and the second clamping members 22 on both sides respectively, so that the distance between the first clamping member 21 and the second clamping members 22 on both sides can be adjusted.

[0050] The adjusting member 60 can adjust the distance between the first clamping member 21 and the second clamping members 22 on both sides, that is, the adjusting member 60 can adjust the distance between the first clamping member 21 and the second clamping member 22 on one side, and also can adjust the distance between the first clamping member 21 and the second clamping member 22 on the other side.

When it is needed to adjust the position of the first clamping member 21 and the second clamping member 22 on one side, the nut 62 on one side can be rotated, so that the distance between the second clamping member 22 and the first clamping member 21 can be adjusted, thereby adapting to the stator core of different sizes.

[0053] Further, the second clamping members 22 on both sides of the first clamping member 21 are connected through the screw rod 61, so that the stator core can be clamped in the radial direction of the stator core, and the position of the second clamping members 22 on both sides of the first clamping member 21 can be adjusted through the connection of the screw rod 61, which is also convenient for installation.

[0054] According to some embodiments of the present application, Figure 3 As shown, the first clamping member 21 is provided with a stator stop member 211, which is located between the adjacent two accommodating cavities 30, so that the stator can be stopped in the axial direction.

[0056] According to some embodiments of the present application, Figure 1 and Figure 3 The first clamping member 21 includes a first clamping plate 212 and a rotating disc 213, and a plurality of second clamping members 22 are arranged on the first clamping plate 212, and the plurality of second clamping members 22 and the first clamping plate 212 form the accommodating cavities 30 for clamping the stator cores, and the rotating disc 213 is arranged at both ends of the first clamping plate 212 and is rotatably arranged on the base 10.

[0058] Further, the rotating disc 213 is arranged at both ends of the first clamping plate 212, and the rotating disc 213 can rotate relative to the base 10, so that the first clamping plate 212 and the plurality of second clamping members 22 rotate together to flip the stator core, so that the stator core can be dipped in paint and baked at different angles.

[0059] In addition, as shown in Figure 5 The first clamping plate 212 includes a first clamping body 70 and a first clamping portion 71, and the first clamping body 70 and the first clamping portion 71 jointly form the plurality of first clamping grooves 40, the first clamping portion 71 is connected to both ends of the first clamping body 70, the first clamping portion 71 includes a first section 711, a second section 712 and a third section 713, one end of the first section 711 is connected to the first clamping body 70, and the second section 712 and the third section 713 are connected to the other end of the first section 711. In this way, the first clamping plate 212 can be adapted to the cylindrical stator core, and can be more closely matched with the cylindrical stator core.

[0060] Further, as shown in Figure 5As shown, the second clamping piece 22 comprises a second clamping body 80 and a second clamping part 81, the second clamping body 80 and the second clamping part 81 jointly form a plurality of second clamping grooves 50, the second clamping part 81 is connected to both ends of the second clamping body 80, the second clamping part 81 comprises a fourth section 811, a fifth section 812 and a sixth section 813, the sixth section 813 is connected to the second clamping body 80, one end of the fifth section 812 is connected to the fourth section 811, and the other end of the fifth section 812 is connected to the sixth section 813. In this way, the second clamping piece 22 can be adapted to the cylindrical stator core, and can make it cooperate more closely with the cylindrical stator core.

[0061] According to some embodiments of the present application, Figure 1 As shown, the base 10 comprises a bottom plate 11, a first support plate 12 and a second support plate 13, the first support plate 12 is connected to the bottom plate 11, the turntable 213 at one end of the first clamping plate 212 is rotatably arranged on the first support plate 12, the second support plate 13 is connected to the bottom plate 11, and the second support plate 13 is arranged in opposite spaced relation to the first support plate 12, and the turntable 213 at the other end of the first clamping plate 212 is rotatably arranged on the second support plate 13.

[0062] The base 10 is mainly composed of the bottom plate 11, the first support plate 12 and the second support plate 13, the first support plate 12 can support one end of the first clamping plate 212, and the second support plate 13 can support the other end of the first clamping plate 212.

[0063] According to some embodiments of the present application, the diameter of the accommodating cavity 30 is d, and d satisfies the relationship: 150mm≤d≤400mm.

[0064] When the stator core needs to be installed in the accommodating cavity 30, the diameter of the stator core with windings is selected to be not less than 150mm. If the diameter of the stator core is less than 150mm, a gap is easily generated between the stator core and the accommodating cavity 30, which causes the stator core to be unable to be effectively clamped, and thus the stator core is easily moved in the accommodating cavity 30. Therefore, the diameter of the stator core is not less than 150mm.

[0065] In addition, the diameter of the stator core with windings is selected to be not more than 400mm. If the diameter of the stator core is more than 400mm, the stator core cannot be placed in the accommodating cavity 30, and thus it is inconvenient to clamp the stator core. Therefore, the diameter of the stator core with windings is not more than 400mm.
