AI Technical Summary
The existing horizontal winding machine cannot achieve automatic bridge crossing, resulting in the inability to complete the winding operation of different wire ducts.
The hook and thread needle sliding assembly, servo motor and slewing power assembly are adopted to control the radial sliding and angle adjustment of the hook and thread needle through the servo motor to achieve accurate alignment of the hook and thread needle entry holes, and the design of arcuate grooves and cylindrical pins ensures that the enameled wire goes from one wire groove to another.
It realizes the automatic bridge function of the horizontal winding machine, adapts to the number of stator and stator slots of different models, reduces processing costs, and improves the smoothness of the winding process.

Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of electrical engineering machinery and equipment, and particularly relates to an overbridge wire-hooking mechanism on a needle-type winding machine. Background Art
[0002] Existing horizontal winding machines cannot perform automatic overbridging to complete winding of different wire grooves. Summary of the Invention
[0003] The object of the present invention is to provide a simple-structured, low-processing-cost, intelligent, controllable and adjustable overbridge device. This device can solve the problem that horizontal winding machines cannot perform automatic overbridging.
[0004] The technical solution of the present invention is as follows:
[0005] The wire-hooking needle, wire-hooking needle seat and slide rail together form a wire-hooking needle sliding assembly; the servo motor and pulley form a rotary power assembly; the servo motor, reduction gear and synchronous belt pulley form an angle adjustment assembly.
[0006] A rotary bearing is installed on the support frame body. The inner ring of the rotary bearing is connected to the mounting flange plate. The inner hole of the mounting flange plate installs a rotary flange through a bearing. One end of the rotary flange is connected to a rotating servo motor. A synchronous belt pulley is installed at the end of the mounting flange plate. The driving pulley is connected to the synchronous belt pulley through a synchronous belt. The reduction gear is connected above the support frame body; the wire-hooking needle and wire-hooking needle seat can slide freely on the slider guide rail. There is a movable cylindrical pin connection between the arc-shaped groove and the slider guide rail in the wire-hooking needle sliding assembly. The angle of the groove determines the installation angle and sliding angle of the wire-hooking needle sliding assembly. The mounting flange plate and the support can rotate freely. The rotary flange can rotate freely between the mounting flange and the support frame body due to the torque provided by the rotary power assembly. Two groups of three arc-shaped grooves are machined on the rotary flange. There is a movable cylindrical pin connection between the arc-shaped groove and the slider guide rail in the wire-hooking needle sliding assembly. When the curve rotary flange rotates, the cylindrical pin slides in the arc-shaped groove of the rotary flange, and the cylindrical pin drives the wire-hooking needle seat and wire-hooking needle to perform a radial linear motion on the slider guide rail; the servo motor can accurately control the rotation angle of the rotary flange, so as to accurately control the radial sliding distance of the wire-hooking needle. A synchronous belt pulley is installed at the end of the mounting flange plate, and the overall angle of the mounting flange plate is controlled by the angle adjustment assembly above the support to ensure that the wire inlet hole of the wire-hooking needle is aligned with the enameled wire by adjusting the angles of the mounting flange plate and the wire-hooking needle seat. The enameled wire is expanded to the outside of the variable-frequency stator end cover. Then, through the circumferential rotation of the stator. The enameled wire is transferred from one wire groove to another wire groove to ensure the smooth progress of the next winding.
[0007] Beneficial effects: 1. Due to the adoption of the above technical solution, the wire-hooking needle can send the enameled wire to a larger radius range from any required radius; therefore, the device can adapt to stators of different models. 2. The grooves of the mounting flange can be processed into different angles according to the needs of the number of stator slots to adapt to different stator requirements. 3. The automatic bridging function can be achieved during the winding process of the horizontal winding machine. Specific embodiments
[0008] The following further elaborates on the technical solution of the present invention by describing the specific embodiments in conjunction with the accompanying drawings.
