Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding devices, in particular to a transformer skeleton winding device. Background Art

[0002] In the winding process of transformer coils, the winding skeleton of the cylindrical structure mostly puts the prefabricated skeleton structure onto the rotating shaft, and realizes uniform coil winding by driving the skeleton to rotate around the axis and move at a uniform speed in the axial direction. In this process, it is necessary to ensure that the position of the skeleton structure relative to the rotating shaft is fixed to ensure the stability of the winding and obtain high-quality wound coils. To achieve this purpose, it is common to provide a skeleton fastening device composed of multiple active actuators. For example, a special limiting structure driven by a cylinder is used to fix the skeleton structure relative to the rotating shaft. Using too many active actuators will make the overall device structure complicated and the working energy consumption excessive. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a transformer skeleton winding device, which ensures the stability of the skeleton position during the coil winding process, simplifies the complexity of loading and unloading actions, and achieves the purpose of reducing working energy consumption.

[0006] Furthermore, the limiting structure includes a zoom section, a sleeve section and a limiting block in sequence from its insertion end to its root. After the zoom section passes through the central axis through hole, the skeleton structure is sleeved and fitted on the sleeve section; the zoom section is wider than the sleeve section, and the zoom section constrains the skeleton structure to fit on the limiting end face of the limiting block.

[0010] Beneficial effects: The utility model provides a transformer skeleton winding device, which adopts a limiting structure as a fixing structure for the skeleton structure winding coil, thereby realizing passive limiting fixation, which ensures the position stability of the skeleton during the winding process without the need to install additional active fastening devices, thereby reducing the complexity of the device, and reducing energy consumption and costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 The figure is a schematic top view of the structure of an embodiment of the utility model. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] As attached Figure 1 The transformer skeleton winding device includes a loading slot 1, a discharge slot 2 and a winding mechanism 3. The loading slot 1 and the discharge slot 2 are arranged side by side. The upper ends of the loading slot 1 and the discharge slot 2 are both provided with slots for the skeleton structure 4 to enter and exit the corresponding slot cavity. The winding mechanism 3 is located on one side of the loading slot 1 and the discharge slot 2. The winding mechanism 3 is provided with a limiting structure 5. The loading slot 1 and the discharge slot 2 are close to the winding mechanism 3. The side is provided with a slot port for the limiting structure 5 to enter and exit the corresponding slot cavity. When the skeleton structure 4 is located in the corresponding slot cavity, the central axis through hole of the skeleton structure 4 is aligned with the slot port, and the limiting structure 5 is inserted and matched with the central axis through hole. The winding mechanism is also provided with a driving module, including a driving device for the limiting structure to move in a three-dimensional space, which is used to cooperate with the loading slot and the discharge slot; and also includes a driving device for driving the limiting structure to rotate around its own axis, which is used to realize the winding of the coil.

[0014] This solution realizes the loading and unloading actions of the skeleton structure relative to the winding mechanism through the cooperation of the limiting structure of the winding mechanism with the loading slot and the unloading slot, and the skeleton structure after loading is limited and fixed by the limiting structure. No additional active fastening device is required to realize the position fixation of the skeleton structure during the winding process. The entire winding process only requires driving the winding mechanism to move and driving the limiting structure to rotate, which simplifies the overall structure of the device and reduces working energy consumption.

[0015] The feeding slot 1 includes a narrow slot cavity 11 and a wide slot cavity 12, and the two ends of the narrow slot cavity 11 are connected to the wide slot cavity 12; the winding drum part in the middle of the skeleton structure 4 is adapted to be placed in the narrow slot cavity 11, and the baffle parts at both ends of the skeleton structure 4 are limited in the wide slot cavity 12. The feeding slot is roughly an I-shaped slot, which is adapted to the common cylindrical skeleton structure. The narrow slot cavity is used to position the inserted skeleton. When the winding mechanism extends from the slot end of the feeding slot and its limiting structure gradually cooperates with the skeleton structure, the baffle at the end of the skeleton is fitted with the end face of the narrow slot cavity to play a limiting role, so as to avoid the skeleton from moving during the insertion and feeding process. After the complete insertion and cooperation, the skeleton is lifted by the winding mechanism so that the skeleton structure is taken out from the slot at the upper end, and then the winding mechanism carries the skeleton back to the winding station to complete the winding operation.

[0016] The limiting structure 5 includes a zoom section 51, a sleeve section 52 and a limiting block 53 in sequence from its insertion end to its root. After the zoom section 51 passes through the central axis through hole, the skeleton structure 4 is sleeved and fitted on the sleeve section 52; the zoom section 51 is wider than the sleeve section 52, and the zoom section 51 constrains the skeleton structure 4 to fit on the limiting end face of the limiting block 53. Among them, the scaling section can be scaled and adjusted in the width direction. In order to ensure that the skeleton does not loosen relative to the rotating shaft and rotate during the winding process, the central axis through hole of the sleeve is mostly set as a square hole, which plays a role of annular limiting. In the natural state, the width of the scaling section is wider than the width of the central axis through hole, and the thickness is adapted to the central axis through hole, and the width, thickness and length of the sleeve section are all adapted to the central axis through hole. When inserting and loading, the scaling section is forced to shrink in width under the thrust, so that the scaling section can enter and pass through the central axis through hole. When the scaling section just completely passes through the central axis through hole, the sleeve section just completely overlaps with the central axis through hole. At this time, the scaling section loses the external force and restores the original width, thereby firmly constraining the skeleton structure on the limit block in the axial direction of the central axis through hole, thereby achieving the effect of limiting and fixing the skeleton structure, and this process only needs to provide a thrust for the limit structure to approach the skeleton structure and insert it relative to the central axis through hole.

[0017] Preferably, the zoom section 51 and the sleeve section 52 are composed of two elastic bodies 50, and a narrow gap is provided between the two elastic bodies 50. The narrow gap is used to provide an escape space. During the insertion process, the ends of the two elastic bodies are forced to approach each other to achieve the purpose of shrinking the width. After the zoom section passes through the central axis through hole, the two elastic bodies are reset under the action of their respective elastic forces, thereby restoring the original size to achieve the effect of limiting. The two elastic bodies are relatively far away from the elastic force generated, and are pressed against the inner wall of the central axis through hole, further tightening and fixing the position of the skeleton structure on the limiting structure. This makes the skeleton more stable during the winding process.

[0018] The discharge chute 2 is provided with a discharge port on one side away from the winding mechanism 3. The end of the discharge chute 2 is a discharge bayonet 21. The opening width of the discharge bayonet 21 is narrower than the end face width of the skeleton structure 4. The bottom of the discharge chute 2 is inclined downward from the discharge bayonet 21 toward the discharge port. When discharging, the wound skeleton is first driven to the top of the discharge chute by the winding mechanism, and then lowered so that the wound skeleton is placed into the discharge chute, and at the same time, the root limit block of the limit structure is located in the discharge bayonet. Then, by retracting the winding mechanism, the skeleton position is constrained by the wall of the discharge chute, so that the limit structure is separated from the skeleton structure and withdrawn from the discharge bayonet to complete the discharging action. The unloaded winding coil slides along the bottom surface of the inclined chute to the discharge port for discharge.

[0019] Preferably, the loading slot 1, the unloading slot 2, and the winding mechanism 3 are arranged in a plurality in the same direction and at equal intervals, and the arrangement direction is consistent with the parallel direction of the loading slot 1 and the unloading slot 2. Multiple winding mechanisms can act synchronously, that is, synchronous winding of multiple transformer coils can be achieved, effectively improving production efficiency.

[0020] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
