Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0020] like Figure 1 and Figure 2 As shown, a universal spindle for a swing-arm type inductor coil winding device includes a hollow cavity structure spindle 1. One end of the spindle 1 is connected to a bearing seat 2, and the other end is connected to an inner shaft 3. A synchronous transmission structure 4 and a ball bearing guide sleeve assembly 5 are sequentially fitted in the middle of the spindle 1. One end of the ball bearing guide sleeve assembly 5 is connected to the inner shaft 3, and the outer side of the ball bearing guide sleeve assembly 5 is connected to a swing arm 6. A guide wheel 7 is provided on the inner shaft 3, and one end of the inner shaft 3 is connected to a quick-change chuck 8. A steering wheel 9 is provided on the swing arm 6, and the swing arm 6 is connected to a lead wire nozzle 10. The spindle 1, guide wheel 7, steering wheel 9, and lead wire nozzle 10 are matched. The quick-change chuck 8 of this invention, through a pre-calibration mechanism, such as the quick-connect design between the quick-change chuck and the inner shaft, ensures the coaxiality of the winding and the height accuracy of the upper end face, eliminating the need for repeated adjustments. With the adjustable structure of the swing arm, operators can easily adapt to a variety of inductor specifications by simply changing the chuck assembly, reducing equipment downtime.
[0021] like Figure 4 As shown, the synchronous transmission structure 4 includes a drive wheel 41, which is sleeved on the outside of the main shaft 1. A synchronous belt 42 is sleeved on the outside of the drive wheel 41, and the synchronous belt 42 matches the synchronous pulley 43. This invention, through the synchronous transmission structure 4 and servo motor control, enables the drive wheel 41 and the synchronous pulley 43 to directly transmit torque, allowing the main shaft 1 and the swing arm 6 to rotate efficiently and in tandem. Combined with the drive control system, the synchronous up-and-down movement of the swing arm driven by the ball guide bushing assembly 4 achieves high-speed, continuous winding, reducing manual operation errors and increasing output per unit time.
[0022] The ball bearing guide bushing assembly 5 includes a guide rail 51. A recessed groove 52 is formed inside the main shaft 1, and the guide rail 51 is mounted on the groove 52. A movable ring 53 is fitted onto the outer side of the main shaft 1, matching the groove 52. A fixed ring 54 is fitted onto the outer side of the movable ring 53 and the groove 52, with one end connected to a mounting base 55. The mounting base 55 is connected to a swing arm 6. Several bearings 56 are fitted onto the outer side of the fixed ring 54, and an outer bushing 57 is fitted onto the outer side of each bearing 56. The active wheel bushing 57 is connected to the main shaft 1, transmitting torque via a synchronous belt 42 and a synchronous pulley 43, enabling the main shaft and swing arm to rotate synchronously and efficiently. Simultaneously, the ball bearing guide bushing assembly 5 drives the swing arm to move up and down, achieving continuity and high speed in the winding process.
[0023] One end of the guide rail 51 is connected to the synchronous transmission structure 4, and the other end of the guide rail 51 is connected to the inner shaft 3. The ball bearing guide bushing assembly 5 of this utility model provides low-friction, high-rigidity motion guidance, ensuring that the swing arm 6 can accurately perform precession motion under the drive of the servo motor, so that the copper wires are tightly and neatly arranged on the winding fixture, reducing coil looseness or misalignment defects, thereby improving product consistency and yield.
[0024] The swing arm 6 includes a first swing arm 61 and a second swing arm 62. Both the first and second swing arms 61 and 62 are fixedly connected to the mounting base 55 via bolts. The arm length of the second swing arm 62 is greater than that of the first swing arm 61. A fixing groove 63 is correspondingly formed inside the second swing arm 62, and the fixing groove 63 is connected to the steering wheel 9. The bottom of the second swing arm 62 is connected to the lead wire nozzle 10. This invention fixes the swing arm 6 to the ball bearing guide sleeve assembly 5. When the moving ring 53 moves along the guide rail 51, the swing arm 6 can move up and down precisely and flexibly. During operation, the servo motor transmits torque through the synchronous transmission structure 4, causing the main shaft 1 and the swing arm 6 to rotate together, allowing the copper wire to be wound onto the winding fixture shaft. Simultaneously, under the drive of the ball bearing guide sleeve assembly 5 in the drive control system, the swing arm 6 moves up and down, ensuring that each turn of copper wire wound on the winding fixture is tightly and neatly arranged.
[0025] like Figure 1 As shown, in a specific embodiment, the copper wire passes through the hollow cavity of the main shaft 1, then exits from below the guide wheel 7, then passes through the fixing groove 63 and exits from the outside of the steering wheel 9, and finally exits from the lead wire nozzle 10 to wind the copper wire onto the core of the winding fixture.
[0026] Although the technical solutions of this utility model have been described and enumerated in detail, it should be understood that modifications to the above embodiments or the adoption of equivalent alternatives are obvious to those skilled in the art. Such modifications or improvements made without departing from the spirit of this utility model are all within the scope of protection claimed by this utility model.
