Technical Field

[0001] The utility model belongs to the technical field of coil processing equipment, and particularly relates to a cylinder-assisted positioning type coil winding machine. Background Art

[0002] A coil is a spring-like structure formed by winding an insulated wire tightly together. In an AC circuit, the coil has the function of blocking the passage of AC current, so the coil can block current, transform voltage, connect, and load in an AC circuit. Coil products have a wide range of uses. They are mainly used in automobile motors, small circuit breakers, etc. Some coils have precise requirements on the outer dimensions, especially export products have clear specifications for the coil ends and coil angles. The commonly used method is to use a special winding machine to automatically process the coil. The current winding machine controls each tool end through the rotation of cams of different shapes to arrange the wire, wrap the head, break the clamp wire, twist the wire, etc. The disadvantage is that the cam control action has low accuracy, and the existing winding machine does not have the auxiliary lifting and positioning function for the front end of the coil. When the winding machine starts winding, it first clamps the wire from top to bottom with a chuck and then rotates to wind it. The chuck easily causes the front end to be pressed down and deformed, so that the angle between the front end of the wire and the coil body is less than 90°, resulting in the need for manual correction of the end. The shape of the wound coil is manually adjusted at the end, and standardized production cannot be achieved. The bending angle of each coil end is not completely consistent, which affects the yield rate and causes problems such as low production efficiency. Summary of the invention

[0013] The utility model is further explained below in conjunction with the accompanying drawings. The technical solution of this embodiment is used to process coils. The front end of this type of coil is a straight portion that is required to be perpendicular to the axis direction of the coil; the tail end of the coil is required to be parallel to the axis direction of the coil; and the middle winding part is a spring-shaped coil body. In the process of the winding machine processing the wire into a coil, the wire feeding device first outputs a section of wire horizontally as the front end of the coil, and then the chuck clamps the wire and rotates it to wind the wire around the thin cylindrical rod, and then other bending devices bend the tail end of the coil, and finally the wire cutting device cuts to complete the processing of a coil.

[0014] like Figure 1 and Figure 2As shown, an auxiliary positioning type coil winding machine includes a winding machine and an auxiliary positioning device. The winding machine mainly includes a machine body 1, an operating table 4 installed on the machine body table, a chuck 5 on the top of the operating table 4, a control table and a display screen. On the circular ring table of the operating table 4, a wire feeding device 401, a bending device, and a wire cutting device are evenly distributed according to angles. A switch is set on the control table, and the display screen is a touch screen with adjustable parameters. The winding machine drives the connected cam to rotate through a motor. The cam is a special-shaped plate. The protruding part of the cam touches and pushes the working end of the corresponding device on the operating table 4 to reciprocate along the radial direction of the operating table 4. By adjusting the cam speed, each device is operated at different times and speeds to process various processes of the coil. The end face of the chuck 5 is provided with a groove 503 which can clamp the outer diameter of the wire. The chuck 5 is mounted on the moving arm of the fuselage 1. The chuck 5 moves and rotates along the up and down direction with the moving arm. The end of the chuck 5 is suspended within the range of the center hole of the ring of the operating table 4. The chuck 5 is a variable diameter cylindrical rod. The lower end is a thin cylindrical rod 501 for winding the coil. The end face of the thick cylindrical rod 502 at the upper end is processed with a groove 503 adapted to the outer diameter of the wire along the conveying direction of the wire at the junction with the thin cylindrical rod 501. The auxiliary positioning device is a servo motor 2 and a telescopic rod 3 driven by the servo motor 2. The servo motor 2 is mounted inside the fuselage 1. The telescopic rod 3 can move up and down according to the moving distance set by the servo motor 2. The end face of the telescopic rod 3 is a plane. The telescopic rod 3 is located within the range of the center hole of the ring of the operating table 4. The telescopic rod 3 and the chuck 5 do not interfere with each other and the operating table 4 when they move up and down.

[0015] As another embodiment, other structures are the same as those of the above-mentioned embodiment, except that the end of the telescopic rod 3 is V-shaped, which is suitable for processing a coil structure in which the angle between the axis of the front end of the coil and the axis of the coil body is greater than 90°. The front end of the wire is bent to a corresponding angle by the telescopic rod 3 pushing the front end of the wire upward and the downward pressure of the chuck 5 to form an opposite force.

[0016] like Figure 3 and Figure 4 As shown, when in use, first, the servo motor 2 controls the telescopic rod 3 to move upward to a height just in contact with the lower surface of the wire output in the horizontal direction to lift the front end of the wire and keep it horizontal, then the clamp 5 moves downward to the groove 503 to just clamp the wire, then the clamp 5 rotates to make the wire wrap around the thin cylindrical rod 501 while the telescopic rod 3 moves downward back to its original position, and then the bending device and the wire cutting device bend and shear the wire according to the preset program to complete the coil processing.

[0017] The above are specific embodiments of the present utility model and the technical principles used. Any modification or equivalent transformation based on the technical solution of the present utility model should be included in the protection scope of the present utility model.
