Description

Technical Field

[0001] This utility model relates to the field of winding tension adjustment technology, specifically an automatic winding tension adjustment auxiliary device for disc motor stator coils. Background Technology

[0002] Copper wire is wound around the rotor core using specialized equipment to form the rotor winding. The quality of the rotor is closely related to the processing quality of the rotor core and the winding quality of the rotor winding.

[0003] A search of Chinese patent CN217600107U reveals a tension adjusting device for a motor rotor winding machine. This device, when installed in its designated position, winds a piece of wire onto the outer walls of two arc-shaped tension plates. Upon energization of a first motor, the output of the first motor drives a stabilizing shaft to rotate. This stabilizing shaft, in turn, drives the forward and reverse threads to rotate. The forward and reverse threads then move a stabilizing thread sleeve, which in turn rotates a connecting rod. The connecting rod then moves the arc-shaped tension plates, expanding the wire during this movement and further increasing the tightness of the wire during winding, thus improving the overall efficiency of the device.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. During the winding process, the movement of the threaded sleeve is controlled by the forward and reverse threads, thereby controlling the movement of the tension plate. The thread drive has increased clearance and poor return accuracy due to friction and wear, which is not suitable for high-speed reciprocating adjustment. Moreover, the adjustment speed is slow and cannot meet the needs of asymmetric winding, thus reducing the efficiency of the automatic winding tension adjustment auxiliary device for disc motor stator coil.

[0007] A tension assist mechanism is disposed on the outer wall of the turntable;

[0008] The tension assist mechanism includes an auxiliary frame fixedly connected to the outer wall of the turntable. A second motor is installed on one side of the outer wall of the auxiliary frame. One end of the output shaft of the second motor is connected to a rotating rod via a coupling. Gears are fixedly connected to the outer walls of both sides of the rotating rod. A first sliding groove is formed on the inner walls of both sides of the top of the auxiliary frame. A first support rod is slidably connected to the inner wall of the first sliding groove. A second sliding groove is formed on the inner walls of both sides of the bottom of the auxiliary frame. A second support rod is slidably connected to the inner wall of the second sliding groove. A rack is fixedly connected to the outer walls of the first and second support rods. A first support frame is slidably connected to the inner wall of the top of the auxiliary frame. A second support frame is slidably connected to the inner wall of the bottom of the auxiliary frame. The first support rod is fixedly connected to the outer wall of the first support frame. The second support rod is fixedly connected to the outer wall of the second support frame. Spare hydraulic rods are installed on the inner walls of both sides of the first and second support frames. A tension plate is fixedly connected to one end of the piston rod of the spare hydraulic rod.

[0009] Preferably, the tension plate is arc-shaped, and the outer wall of the tension plate is provided with a ceramic coating.

[0010] Preferably, the gear meshes with the rack, and the first support rod and the second support rod are located on both sides of the gear.

[0011] Preferably, hydraulic dampers are installed on the inner walls of both sides of the auxiliary frame, and one end of the piston rod of each of the two hydraulic dampers is fixedly connected to the outer wall of the first support frame and the second support frame, respectively.

[0013] This utility model provides an automatic winding tension adjustment auxiliary device for disc motor stator coils through improvements, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model is equipped with a stabilizing plate, a tension plate, a gear, a rack, a rotating rod, and a spare hydraulic rod. The rack on the second support rod is connected to the right side of the gear, and the directions are opposite. When the gear rotates, it quickly drives the first support frame to rise through the rack, and drives the second support frame to fall. The distance between the two tension plates increases, thereby adjusting the tension. The first motor controls the rotation of the turntable and the auxiliary frame to perform automatic winding. The meshing transmission of the gear and rack supports instantaneous large-range tension adjustment. Moreover, the tension plates on the first or second support frame can be adjusted separately through the spare hydraulic rod to perform asymmetrical winding tension adjustment. The rolling friction resistance is smaller, the transmission efficiency is higher, and there is no self-locking problem. It is suitable for high-speed reciprocating adjustment and can perform asymmetrical winding according to the adjustment requirements, thus improving the efficiency of the automatic winding tension adjustment auxiliary device for disc motor stator coils.

[0015] Secondly, this utility model incorporates a tension plate, a ceramic coating, and a hydraulic damper. The ceramic coating on the outer wall of the tension plate provides excellent wear resistance, and the hydraulic damper inside the auxiliary frame can suppress the rebound of the tension plate and prevent the wire from loosening when the winding stops suddenly, thus improving the safety of the automatic winding tension adjustment auxiliary device for the disc motor stator coil.

[0027] The tension auxiliary mechanism includes an auxiliary frame 5 fixedly connected to the outer wall of the turntable 4. A motor 2 9 is installed on one side of the outer wall of the auxiliary frame 5. One end of the output shaft of the motor 2 9 is connected to a rotating rod 12 via a coupling. Gears 13 are fixedly connected to the outer walls of both sides of the rotating rod 12. A sliding groove 1 is opened on the inner walls of both sides of the top of the auxiliary frame 5. A support rod 14 is slidably connected to the inner wall of the sliding groove 1. A sliding groove 2 is opened on the inner walls of both sides of the bottom of the auxiliary frame 5. A support rod 2 15 is slidably connected to the inner wall of the sliding groove 2. A rack 17 is fixedly connected to the outer walls of the support rod 1 14 and the support rod 2 15. A support frame 1 6 is slidably connected to the inner wall of the top of the auxiliary frame 5. A support frame 2 10 is slidably connected to the inner wall of the bottom of the auxiliary frame 5. The support rod 14 is fixedly connected to the outer wall of the support frame 1 6. The support rod 2 15 is fixedly connected to the outer wall of the support frame 2 10. A spare hydraulic rod 8 is installed on the inner walls of both sides of the support frame 1 6 and the support frame 2 10.

[0028] Furthermore, the tension plate 16 is arc-shaped, and the outer wall of the tension plate 16 is provided with a ceramic coating 11. The gear 13 meshes with the rack 17, and the first support rod 14 and the second support rod 15 are located on both sides of the gear 13.

[0030] Working principle: When using the automatic winding tension adjustment auxiliary device for disc motor stator coils, the tension of the winding is adjusted by the tension plates 16 set at the top and bottom of the auxiliary frame 5.
