Description

Technical Field

[0001] The utility model relates to the technical field of wind power generators, in particular to a wire twisting device for motor stator lead wires. Background Art

[0002] The stator of a motor usually consists of a stator core and a stator winding. The stator winding cooperates with the embedded wire on the stator core. The stator winding usually has a lead wire for connecting to a power source. For example, a general motor has a positive lead wire and a negative lead wire. The positive or negative lead wire is composed of a plurality of enameled wires. After being wound into a stator winding by a winding machine, the plurality of enameled wires forming the positive or negative lead wires are in a loose state. These loose enameled wires need to be twisted into a strand so that the positive or negative lead wire is spirally shaped, so as to facilitate the subsequent provision of an insulating sleeve on the outside of the enameled wire.

DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figures 1 to 7 As shown, the twisting device of the motor stator lead wire of the utility model includes a stator clamping tool A, a workbench B, a lifting mechanism C, a limiting mechanism D, a clamping and rotating mechanism E, and a lifting and driving mechanism F. Each part and the relationship between each part are described in detail below.

[0035] The stator clamping fixture A is used to accommodate the stator, and the workbench B is used to connect with the jacking mechanism C and the lifting drive mechanism F.

[0036] The lifting mechanism C is connected to the workbench B, and the stator clamping tool A cooperates with the lifting mechanism C. In the utility model, the lifting mechanism C includes a first lifting driver 1, a fixed plate 2, and a first movable seat 3. The fixed plate 2 is fixed to the workbench B, the first lifting driver 1 is fixed to the fixed plate 2, the power output end of the first lifting driver 1 passes through the fixed plate 2 and is connected to the first movable seat 3, and the stator clamping tool A cooperates with the first movable seat 3.

[0037] A through hole is provided on the workbench B, and the fixed plate 2 is fixed to the workbench B after crossing the through hole on the workbench B. A first bracket 1a is fixed on the fixed plate 2. The first lifting drive 1 can adopt a linear drive such as a cylinder, a hydraulic cylinder, and an electric screw. In the utility model, the first lifting drive 1 preferably adopts a cylinder, and the cylinder body of the cylinder is fixed to the first bracket 1a. The piston rod of the cylinder passes through the fixed plate 2 and is fixed to the first movable seat 3. The first lifting drive 1 drives the first movable seat 3 to perform a lifting movement along the workbench B, so that the stator clamping tooling A located on the first movable seat 3 follows the first movable seat 3 to perform a lifting movement.

[0038] The lifting mechanism C also includes a clamping assembly for applying pressure to the stator clamping tool A. There are two clamping assemblies in the utility model and they are arranged on both sides of the stator clamping tool A. The clamping assembly includes a second lifting drive 4, a first connecting rod 5, a pressing arm 6, a second connecting rod 7, a connecting component 8, and a third connecting rod 9. The second lifting drive 4 can adopt a linear drive such as a cylinder, a hydraulic cylinder, and an electric screw. In the utility model, the second lifting drive 4 preferably adopts a cylinder. The second lifting drive 4 is fixed on the first movable seat 3, one end of the first connecting rod 5 is hinged to the power output end of the second lifting drive 4, the other end of the first connecting rod 5 is hinged to one end of the pressing arm 6, one end of the second connecting rod 7 is hinged to the power output end of the second lifting drive 4, the connecting component 8 is fixed to the second lifting drive 4, one end of the third connecting rod 9 is hinged to the connecting component 8, the other end of the second connecting rod 7 is hinged to the third connecting rod 9, and the other end of the third connecting rod 9 is hinged to the pressing arm 6.

[0039] A notch A1 is provided on the stator clamping tool A. When the stator clamping tool A needs to be clamped, the piston rod of the second lifting drive 4 extends to cause the first connecting rod 5, the second connecting rod 7, the third connecting rod 9, and the pressing arm 6 to swing, so that the pressing arm 6 enters the notch A1 from the side of the stator clamping tool A, so that the clamping assembly applies pressure to the stator clamping tool A and presses the stator clamping tool A onto the first movable seat 3 to prevent the stator clamping tool A from axial and circumferential movement.

[0040] The limit mechanism D limits the rising position of the stator, and the limit mechanism D is located above the lifting mechanism C. Since the stator clamping fixture A follows the first movable seat 3 to perform the lifting and lowering movement, when the stator clamping fixture A rises to the wire twisting position, the upper end of the stator in the stator clamping fixture A forms abutment with the lower end surface of the limit mechanism D, thereby limiting the stator clamping fixture A from continuing to rise. Since the lower end of the stator is positioned by the step in the inner hole of the stator clamping fixture A, both ends of the stator are positioned, thereby limiting the axial movement of the stator during the wire twisting process.

The pressure block base 10 is fixed to the lifting drive mechanism F, the linear driver 11 is fixed to the pressure block base 10, one end of the pressure block 12 is bent to form a first bent portion, and the other end of the pressure block 12 is bent to form a second bent portion 12a for cooperating with the circumferential surface of the stator, one end of the linear driver 11 is fixed to the first bent portion on the pressure block 12, a clearance notch is provided on the pressure block base 10, and the middle part of the pressure block 12 cooperates with the clearance notch.

[0042] During actual operation, the lower end of the pressure block base 10 faces the upper end of the stator to form a restriction, and the piston rod of the linear drive 11 retracts to drive the pressure block 12 to move, so that the second bending portion 12a is matched with the circumferential surface of the stator, thereby avoiding the stator from tilting, that is, ensuring that the stator remains vertical during the twisting process.

The third lifting driver 20 can adopt linear drivers such as cylinders, hydraulic cylinders, and electric screws. In the utility model, the third lifting driver 20 preferably adopts a cylinder. The third lifting driver 20 is fixed on the support frame 13. The output end of the third lifting driver 20 is connected to one end of the coupling 21, and the other end of the coupling 21 is connected to one end of the transmission shaft 22.

[0051] Before the enameled wire is twisted, the angle formed by the axial direction of the enameled wire and the radial direction of the stator is less than 10°. Therefore, the axial direction of the enameled wire needs to be folded to a state parallel to the axial direction of the clamping unit. Therefore, the utility model also includes a clamping wire folding mechanism G that folds the enameled wire on the stator to be parallel to the axial direction of the clamping rotating mechanism E.

[0056] The distance between the finger cylinder 31 and the stator clamping fixture A can be adjusted by the lateral driving unit, so that the present invention is suitable for twisting wires of stators with different diameters (different stator outer diameters result in different sizes of the stator clamping fixture A).

[0057] The working steps of this utility model are as follows:

[0058] S1, the stator clamping tool A equipped with the stator is fitted on the first movable seat 3, the piston rod of the second lifting drive 4 is extended, the first connecting rod 5, the second connecting rod 7, the third connecting rod 9, and the pressing arm 6 are swung, and the pressing arm 6 enters the recess A1 from the side of the stator clamping tool A, so that the clamping assembly applies pressure to the stator clamping tool A, and presses the stator clamping tool A on the first movable seat 3.

[0059] S2, the first lifting driver 1 drives the first movable seat 3 to rise, and the stator clamping fixture A rises with the first movable seat 3, and the upper end of the stator clamping fixture A abuts against the lower surface of the pressure block base 10. The first lifting driver 1 stops power output, and the stator clamping fixture A keeps abutting against the pressure block base 10. The piston rod of the linear driver 11 retracts to drive the pressure block 12 to move, so that the second bending portion 12a is matched with the circumferential surface of the stator.

[0060] S3, the first linear drive 35 drives the second bracket 27 to move, so that the finger cylinder 31 installed on the second bracket 27 moves toward the stator clamping fixture A, and the multiple enameled wires on the stator in the stator clamping fixture A passively enter the clamping range of the finger cylinder 31, and the finger cylinder 31 works to clamp the enameled wires. The second rotary drive 28 works to drive the rotating shaft 30 and the finger cylinder 31 to rotate in turn, thereby rotating the finger cylinder 31 clamping the enameled wires, so that the multiple enameled wires are folded to a state parallel to the axis of the clamping unit.
