[0002] In the process of winding the stator of an electric motor, it is necessary to hook a copper wire with a stranding rod and rotate the stranding rod to wind the copper wire around the insertion pin of the stator to complete the process of stranding the insertion pin.

[0003] As disclosed in a prior patent, a stranding rod with a winding angle (application number: 202123326148.9) includes an outer stranding sleeve and an inner stranding sleeve. The outer stranding sleeve is sleeved on the inner stranding sleeve, the outer wall of the inner stranding sleeve is in close contact with the inner wall of the outer stranding sleeve, the inner stranding sleeve can rotate within the outer stranding sleeve and drive the outer stranding sleeve to rotate in the same direction, and a stranding opening is provided at the lower end of the inner stranding sleeve, the size of which changes according to the angle of rotation of the inner stranding sleeve relative to the outer stranding sleeve; the wire body is wrapped through the stranding opening, then the stranding opening is contracted by rotating the inner stranding sleeve, and then the inner stranding sleeve drives the outer stranding sleeve to rotate in the same direction to drive the wire body to wind. However, this kind of stranding rod has a complex structure and higher cost. Summary of the Utility Model

[0004] In order to solve the above problems, the technical object of the utility model is to provide a stranding rod with a simple structure and lower cost; and this stranding rod can strand in both forward and reverse directions, making it more convenient to use.

[0005] Another technical object of the utility model is to provide a stranding mechanism with a simple structure and lower cost; and this stranding mechanism can strand in both forward and reverse directions, making it more convenient to use.

[0006] In order to achieve the above object, the technical solution of the utility model is as follows.

[0007] A stranding rod, which includes:

[0008] A rod body, with an insertion hole provided at the lower end of the rod body;

[0009] Two stranding bodies, which are fixedly arranged at the lower end of the rod body and are located on both sides of the insertion hole respectively. A wire passing groove communicating with the insertion hole is formed between the two stranding bodies; a stranding groove is formed between the stranding body and the rod body, and the stranding grooves at the two stranding bodies are both communicated with the wire passing groove.

[0010] When this stranding rod works, the insertion hole is aligned with the insertion pin of the stator and lowered so that the insertion pin of the stator extends into the insertion hole; at this time, the copper wire obliquely passes through the wire passing groove, and the higher end of the copper wire corresponds to both stranding grooves; then, by rotating the stranding rod clockwise or counterclockwise and rising, the higher end of the copper wire is wound around the insertion pin of the stator from bottom to top through the corresponding stranding groove to complete the stranding process.

[0011] In this stranded wire rod, it is a single-rod structure, and compared with the existing composite stranded wire rod composed of multiple parts, it has a simpler structure and lower cost; and the stranded wire rod is more efficient during production and assembly; in addition, based on the fact that there are two stranded wire bodies in the stranded wire rod, two stranded wire grooves are formed with the rod body respectively, so that no matter whether the stranded wire is rotated clockwise or counterclockwise, the stranded wire process can be completed through the corresponding one of the two stranded wire grooves, so that the stranded wire rod can meet more usage requirements and is more convenient to use.

[0012] Furthermore, the twisted wire rod is integrally formed, which makes the production and assembly of the twisted wire rod more convenient.

[0013] Furthermore, the stranded wire body is in an "L" shape as a whole.

[0014] Furthermore, a slip-off prevention portion is provided on one side of the stranded wire body that extends toward the wire trough, and a first avoidance groove is provided on the slip-off prevention portion at a location corresponding to the insertion hole. The slip-off prevention portion prevents the copper wire from escaping the stranded wire trough during winding. Simultaneously, the first avoidance groove avoids the stator pins, allowing them to smoothly enter the insertion hole.

[0015] Furthermore, a second escape groove is provided at the lower end of the rod body, connected to the insertion hole. The second escape groove extends through the end surface of the lower end of the rod body, connecting to the stranding grooves of both stranding bodies via the wire passing groove. The provision of this second escape groove allows the higher end of the copper wire to be avoided during stranding, thereby preventing the lower end of the rod body from contacting the higher end of the copper wire during stranding and causing the copper wire to break.

[0016] Furthermore, the second avoidance groove is semicircular as a whole.

[0017] Furthermore, a third avoidance groove is formed between the lower end of the rod and the side of the two stranded wire bodies facing away from the stranding slots. The third avoidance groove is connected to the wire passing slot. The provision of the third avoidance groove prevents the lower end of the copper wire from being wound around the stator pins when the stranded wire bodies pass through the stranding slots and wind the higher end of the copper wire from bottom to top, thereby preventing the subsequent stator winding from being affected.

[0018] A stranding mechanism, which includes a lifting bracket, a rotating bracket, a lifting cylinder, a rotating motor, a rotating shaft and the stranding rod. The lifting cylinder is fixedly arranged on the lifting bracket, the lifting cylinder is drivingly connected with the rotating bracket, the rotating motor is fixedly arranged on the rotating bracket, and the rotating motor is drivingly connected with the rotating shaft. The rotating shaft is connected to the upper end of the stranding rod. In this mechanism, the rotating motor drives the rotation of the rotating shaft, the rotating group drives the rotation of the stranding rod, and the lifting cylinder can also drive the lifting of the rotating bracket, so as to drive the stranding rod to lift, and realize the control of the lifting and rotation of the stranding rod to complete the stranding process; based on the structural design of the stranding rod, the stranding mechanism is relatively simpler and has lower cost compared with the existing stranding structures; and this stranding mechanism can strand in both forward and reverse directions, making it more convenient to use.

[0019] Further, the rotating bracket includes a first bracket, a second bracket and a guide shaft. The first bracket and the second bracket are respectively located on the upper and lower sides of the lifting bracket. The rotating motor is fixedly arranged on the first bracket. The rotating shaft passes through the lifting bracket and then through the second bracket to be connected with the stranding rod, and the rotating shaft is rotatably connected with the second bracket; the upper end of the guide shaft is fixedly arranged on the first bracket, the lower end of the guide shaft passes through the lifting bracket and is fixedly arranged on the second bracket, and the guide shaft is vertically movably connected with the lifting bracket; the lifting cylinder is drivingly connected with the second bracket.

[0020] The lifting cylinder drives the second bracket to move up and down. The second bracket synchronously drives the first bracket and the stranding rod to move up and down through the rotating shaft, and drives the guide shaft to move up and down at the lifting bracket for guiding, so as to control the stability of the stranding rod during the up and down movement.

[0021] Further, the rotating shaft is rotatably connected with the second bracket through a bearing, and the guide shaft is vertically movably connected with the lifting bracket through a linear bearing.

[0022] Further, there are multiple rotating motors, rotating shafts and stranding rods. Multiple lifting cylinders, rotating motors, rotating shafts and stranding rods are symmetrically arranged on both sides of the lifting cylinder respectively;

[0023] The number of guide shafts is multiple, and multiple guide shafts are symmetrically arranged on both sides of the lifting cylinder respectively; this symmetrical arrangement makes the stranding mechanism work more smoothly.

[0024] Further, the lifting cylinder is fixedly arranged on the upper side of the lifting bracket, and the lifting cylinder passes through the lifting bracket to be drivingly connected with the second bracket; a fourth avoidance groove is arranged on the first bracket corresponding to the lifting cylinder, and the lifting cylinder passes through the fourth avoidance groove.

[0025] The beneficial effects of the present utility model are as follows: the structure is simpler and the cost is lower; moreover, when the stranding rod is being produced and assembled, the efficiency is also higher; in addition, based on the fact that there are two stranding bodies on the stranding rod to respectively form two stranding grooves with the rod body, no matter whether the stranding rod rotates clockwise or counterclockwise for stranding, the stranding process can be completed through one of the two corresponding stranding grooves, so that the stranding rod can meet more usage requirements and is more convenient to use.
