Description

Technical Field

[0001] The utility model relates to the technical field of winding equipment, in particular to a head protection structure for a winding machine, a winding positioning mechanism and a winding machine. Background Art

[0002] The stator core usually includes teeth arranged at intervals and a yoke for connecting the teeth. When winding, the enameled wire needs to be wound in multiple layers at each tooth position to form a coil winding, and each layer of coils should form a dense structure arranged in sequence. During the winding process of the common flying fork winding machine, the flying fork drives the winding nozzle to rotate along a circular or circular-like path, and moves along the axial direction of the flying fork at the same time, so that the coils are wound and arranged in sequence, but the outer contour of the tooth winding area is rectangular, such as Figure 6 As shown in the figure, due to the large difference between the rotation path of the wire nozzle and the shape of the tooth contour, the wire nozzle is prone to the problem of axial movement when winding the short side of the tooth, that is, "wire floating". Wire floating will cause the coil to be arranged messily and loosely during winding, and even accumulate, thereby affecting the subsequent process and motor performance. Utility Model Content

Preferably, the auxiliary head guard includes an upper auxiliary head guard 531 and a lower auxiliary head guard 532 which are separately arranged, and the upper auxiliary head guard 531 and the lower auxiliary head guard 532 are respectively arranged on the upper side and the lower side of the iron core 61, and the upper arc portion and the lower arc portion are respectively arranged on the side of the upper auxiliary head guard 531 and the lower auxiliary head guard 532 close to the iron core 61. The split design of the auxiliary head guard facilitates operations such as movement and replacement.

[0026] The auxiliary head guard lifting assembly also includes a secondary head guard translation assembly and a secondary head guard lifting assembly. The secondary head guard translation assembly includes a third translation guide rail 541 and a secondary head guard translation platform 542. The third translation guide rail 541 is arranged in a horizontal plane along a direction perpendicular to the iron core 61.

The upper secondary head guard 531 and the lower secondary head guard 532 are respectively fixedly mounted on the second lifting plate 553 and the secondary head guard translation platform 542. Through the above structure, the auxiliary head guard translation platform 542 drives the upper auxiliary head guard 531 and the lower auxiliary head guard 532 to synchronously approach or move away from the iron core 61 in the horizontal direction, and the second lifting plate 553 drives the upper auxiliary head guard 531 to approach or move away from the lower auxiliary head guard 532 in the vertical direction, thereby adjusting the relative distance between the two auxiliary head guards and meeting the guiding needs of the enameled wire during the winding process.

During winding, the main head guard 511 and the auxiliary head guard move to the front and rear sides of the tooth to be wound. The main head guard 511 and the auxiliary head guard are arranged relative to each other in the horizontal direction and move synchronously, thereby limiting the winding trajectory of the enameled wire in the direction of the flying fork axis, ensuring that the winding on the long side and short side of the tooth can be kept uniform, neat and dense. The left head guard 512 and the right head guard 513 move to the left and right sides of the tooth to be wound, so as to protect the enameled wire on the side of the tooth when the flying fork switches between different teeth, and prevent the enameled wire from being scratched or damaged during the winding process. Preferably, the main head guard 511, the left head guard 512 and the right head guard 513 are provided with an avoidance groove in the middle, and the avoidance groove is arranged corresponding to the shape of the tooth of the iron core 61, so that the tooth can be embedded in the head guard during winding, so that the head guard can be inserted into the gap between the teeth to position and protect at various positions of the winding.

[0029] It also includes a tooling 62 that supports the iron core 61, and a tooling translation mechanism 63 that drives the tooling 62 and the iron core 61 to move horizontally. The tooling 62 is clamped on one side of the yoke of the iron core 61. The tooling translation mechanism 63 can be a lead screw, a linear guide rail or other mechanisms that can achieve linear transmission.

[0030] The main head guard translation assembly includes a second translation guide rail 521, which is arranged on the first translation plate 422 and parallel to the first translation guide rail 421.
