Description

Technical Field

[0001] This utility model relates to the field of stator winding tooling technology, specifically to a stator winding tooling. Background Technology

[0002] The stator is the stationary part of a rotating electrical machine such as an electric motor or generator, and is an important component of the machine. Its main function is to interact with the rotor to realize the conversion between electrical energy and mechanical energy. In an electric motor, the stator receives electrical energy and generates a rotating magnetic field, driving the rotor to rotate and thus outputting mechanical energy; in a generator, the rotor rotates under the action of external forces, and the stator cuts the magnetic field lines generated by the rotor, thereby generating an induced electromotive force to output electrical energy.

[0003] The stator consists of three parts: the stator core, the stator winding, and the frame. During the stator production process, a stator winding machine is needed to wind copper wires onto the stator base to form the winding.

[0004] During the stator winding process, fixing fixtures are needed to secure the stator. However, common stator winding fixtures have poor applicability and cannot be used to fix stators with different inner diameters, which greatly reduces their practicality.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a stator winding tool that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A stator winding fixture includes: a machine base; and a fixing mechanism for fixing the stator.

[0009] The fixing mechanism includes: a bidirectional screw rotatably mounted on the machine base; a first motor that drives the bidirectional screw to rotate; a movable block threadedly connected to the bidirectional screw; a connecting rod hingedly mounted on the movable block; a clamping plate hingedly mounted on the end of the connecting rod; and a fixing rod that limits the movement of the movable block.

[0010] Furthermore, the fixing rod penetrates the side wall of the moving block, and the top end of the fixing rod is fixedly connected to the fixing plate, while the bottom end of the fixing rod is fixedly connected to the machine base.

[0011] Furthermore, multiple clamping plates are provided and are evenly distributed in a ring shape along the axial direction of the bidirectional screw.

[0012] Furthermore, it also includes: an ejection mechanism that ejects the wound stator;

[0013] The ejection mechanism includes: a fixed plate fixedly installed inside the machine base; a threaded rod rotatably installed on the fixed plate; a threaded tube threadedly connected to the threaded rod; an annular plate fixedly installed at the top end of the threaded tube; a drive assembly for rotating the threaded rod; and a limiting assembly for limiting the position of the threaded tube.

[0014] Furthermore, the drive assembly includes: a first bevel gear rotatably mounted inside the machine base; a second motor driving the first bevel gear to rotate; a second bevel gear meshing with the first bevel gear; and the second bevel gear being fixedly mounted on the bottom end of the threaded rod.

[0015] Furthermore, the limiting component includes: a limiting tube inserted and installed on the machine base; a limiting strip fixedly installed on the threaded tube; a limiting groove is formed inside the limiting tube, and the limiting strip is slidably installed in the limiting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model discloses a stator winding fixture. Through the setting of a fixing mechanism, it can fix stators with different inner diameters, thereby improving the applicability and practicality of the fixture. Moreover, multiple clamping plates are provided, so that the stator can be clamped and fixed from different directions, thereby improving the stability of the stator fixing. In addition, multiple clamping plates expand outward simultaneously, thereby automatically correcting the stator, making the fixed stator stable and improving the accuracy of stator processing.

[0026] like Figures 1 to 4 As shown, this utility model discloses a stator winding fixture, including: a machine base 1; and a fixing mechanism for fixing the stator.

[0027] The fixing mechanism includes: a bidirectional screw 3 rotatably mounted on the machine base 1; a first motor 2 that drives the bidirectional screw 3 to rotate, the first motor 2 being fixedly mounted inside the machine base 1; a movable block 4 threadedly connected to the bidirectional screw 3; a connecting rod 7 hingedly mounted on the movable block 4; a clamping plate 8 hingedly mounted on the end of the connecting rod 7; and a fixing rod 6 that limits the movement of the movable block 4. The fixing rod 6 passes through the side wall of the movable block 4, and its top end is fixedly connected to the fixing plate 5, and its bottom end is fixedly connected to the machine base 1. Multiple clamping plates 8 are provided and are evenly distributed in a ring along the axial direction of the bidirectional screw 3. There are two movable blocks 4, and multiple connecting rods 7 are hingedly mounted on each of the two movable blocks 4. Two connecting rods 7 are hingedly mounted on each clamping plate 8, and the other ends of the two connecting rods 7 are hinged to the adjacent movable blocks 4.

[0028] When the stator is fixed, it is sleeved on the outside of multiple clamping plates 8. At this time, the first motor 2 is started to drive the bidirectional screw 3 to rotate. The bidirectional screw 3 drives the two moving blocks 4 to move simultaneously. Through the limiting effect of the fixed rod 6, the two moving blocks 4 move closer or further away from each other along the axis of the bidirectional screw 3.

[0029] When two moving blocks 4 approach each other, they can drive the adjacent connecting rods 7 to move. The connecting rods 7 drive the clamping plates 8 to move, thereby driving multiple clamping plates 8 to expand outwards at the same time, thus clamping and fixing the stator.

[0030] Since the positions of the multiple clamping plates 8 can be adjusted, stators with different inner diameters can be fixed, which improves the applicability and practicality of the tooling.

[0031] Furthermore, multiple clamping plates 8 are provided, which can clamp and fix the stator from different directions, thereby improving the stability of the stator fixation.

[0032] In addition, multiple clamping plates 8 extend outwards simultaneously, thereby automatically correcting the stator, making the fixed stator stable, and improving the accuracy of stator processing.

[0033] Once the stator is processed, the first motor 2 is started to rotate in reverse, thereby driving multiple clamping plates 8 to retract inward, releasing the stator from its fixed state, thus making it easier to remove the stator.

[0034] It also includes: an ejection mechanism for ejecting the wound stator; the ejection mechanism includes: a fixed plate 5 fixedly installed in the machine base 1; a threaded rod 12 rotatably installed on the fixed plate 5; a threaded tube 13 threadedly connected to the threaded rod 12; an annular plate 14 fixedly installed at the top end of the threaded tube 13; a drive assembly for driving the threaded rod 12 to rotate; and a limiting assembly for limiting the threaded tube 13; the drive assembly includes: a first bevel gear 10 rotatably installed in the machine base 1; a second motor 9 driving the first bevel gear 10 to rotate; a second bevel gear 11 meshing with the first bevel gear 10; the second bevel gear 11 fixedly installed at the bottom end of the threaded rod 12; the limiting assembly includes: a limiting tube 15 inserted and installed on the machine base 1; and a limiting strip 16 fixedly installed on the threaded tube 13; a limiting groove is opened in the limiting tube 15, and the limiting strip 16 is slidably installed in the limiting groove.

[0035] When the stator is fixed, the bottom of the stator abuts against the top of the annular plate 14. The annular plate 14 provides support for the stator.

[0036] After the stator is processed, the second motor 9 is started to drive the first bevel gear 10 to rotate. The first bevel gear 10 drives the second bevel gear 11 to rotate, which in turn drives the threaded rod 12 to rotate. The threaded rod 12 drives the threaded tube 13 to move. The threaded tube 13 drives the limiting strip 16 to slide in the limiting groove. Through the cooperation between the limiting strip 16 and the limiting tube 15, the threaded tube 13 moves upward along the axial direction of the threaded rod 12, which in turn drives the annular plate 14 to move upward, and in turn drives the processed stator to move upward, making it easier for the workers to remove the stator and improving the convenience of the operation.

[0037] Working principle: When fixing the stator, the stator is sleeved on the outside of multiple clamping plates 8. At this time, the first motor 2 is started to drive the bidirectional screw 3 to rotate. The bidirectional screw 3 drives two moving blocks 4 to move simultaneously. Through the limiting action of the fixing rod 6, the two moving blocks 4 move closer or further away from each other along the axial direction of the bidirectional screw 3. When the two moving blocks 4 move closer to each other, they can drive the adjacent connecting rod 7 to move. The connecting rod 7 drives the clamping plates 8 to move, thereby causing multiple clamping plates 8 to expand outwards simultaneously, thus clamping and fixing the stator. Since the position of multiple clamping plates 8 can be adjusted... The tooling can be adjusted to fix stators with different inner diameters, improving its applicability and practicality. Furthermore, multiple clamping plates 8 are provided, allowing for clamping and fixing of the stator from different directions, thus improving the stability of the stator fixation. Additionally, the simultaneous outward expansion of multiple clamping plates 8 automatically corrects the stator, ensuring stability after fixing and improving the precision of stator machining. Once the stator machining is complete, the first motor 2 is started to rotate in the reverse direction, causing the multiple clamping plates 8 to retract inward, releasing the stator from its fixed state and facilitating its removal.
