[0002] When producing transformers, equipment is usually used to complete highly repetitive tasks such as winding, rubber coating, and core installation, while manual work is used to complete material preparation, loading and unloading, and appearance quality inspection. Specifically, when winding the transformer, the transformer frame is manually installed on the winding shaft of the transformer winding machine. After the wire is wound on the transformer frame, the servo motor drives the winding shaft to rotate to complete the winding. Then, the transformer frame that has been wound is manually removed, and the above actions are repeated for a new round of winding work.

[0039] Example

[0040] Please refer to Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a transformer winding tool for use with a transformer winding machine to automatically feed and unload the transformer winding machine. Specifically, the transformer winding machine is provided with a winding shaft, the transformer winding tool is located directly in front of the transformer winding machine and corresponds to the position of the winding shaft, the winding shaft is driven by a servo motor to move and rotate, and the winding shaft is used to be plugged and matched with the core hole of the transformer frame. It should be noted that the transformer winding machine is a prior art and will not be described here.

[0041] Specifically, the transformer winding tooling includes a base plate 10 and a positioning seat 11 arranged on the base plate 10, and the positioning seat 11 is provided with an upwardly opening loading trough 111 and a lower loading trough 112 side by side. Among them, the loading trough 111 is provided with a first opening 1111 facing the first side 113 of the positioning seat 11, and a second opening 1112 is provided facing the second side 114 opposite to the first side 113, and the first opening 1111 and the second opening 1112 provide avoidance space for the movement of the winding shaft. In actual operation, a person places the transformer skeleton to be wound into the loading trough 111 and fixes it in a fixed position. Under the drive of the servo motor, the winding shaft extends from the first opening 1111 into the loading trough 111 and is plugged into the core hole of the transformer skeleton. Then, the servo motor drives the winding shaft to lift upward to take the transformer skeleton away from the loading trough 111, so as to realize automatic loading of the transformer winding machine. The transformer winding machine then drives the winding shaft to rotate through the servo motor to complete the winding work of the transformer skeleton. The discharge chute 112 is provided with a discharge port 1121 toward the first side 113, and the discharge chute 112 is provided with a third opening 1122 toward the second side 114. The discharge port 1121 and the third opening 1122 provide avoidance space for the movement of the winding shaft, and the width of the discharge port 1121 is smaller than the width of the discharge chute 112. In actual operation, after the transformer winding machine completes the winding work of the transformer skeleton, the servo motor drives the winding shaft to move with the wound transformer skeleton toward the positioning seat 11, and extends into the discharge chute 112 from the opening above the discharge chute 112, and then the winding shaft is pulled out from the discharge port 1121. Since the width of the discharge port 1121 is smaller than the width of the discharge chute 112, the transformer skeleton abuts against the inner wall of the discharge chute 112 when the winding shaft is pulled out, and the transformer skeleton plugged on the winding shaft is automatically removed under the action of force, thereby realizing automatic unloading.

[0042] In addition, in order to save the connection of wires and two clamping processes, one side of two independent transformer frames is connected so that the two transformer frames can be folded. After one clamping, the two transformer frames can be processed together. After the processing is completed, they can be folded in half and used in pairs. Therefore, the feeding trough 111 is arranged in a "W"-shaped structure, which matches the shape of the two folded transformer frames, and can cooperate with the processing of the two transformer frames connected on one side, which can simplify the process and improve production efficiency.

[0043] like Figure 4 As shown, in this embodiment, the feeding trough 111 includes a transverse groove 1113, a first T-shaped groove 1114 and a second T-shaped groove 1115, and the first T-shaped groove 1114 and the second T-shaped groove 1115 are symmetrically arranged with the transverse groove 1113 as the symmetry axis. That is, the first T-shaped groove 1114 and the transverse groove 1113 form an "I"-shaped groove body, and the second T-shaped groove 1115 and the transverse groove 1113 form another "I"-shaped groove body, and the "I"-shaped groove body is adapted to the shape of the transformer skeleton, and the two "I"-shaped groove bodies are connected to form a "W"-shaped structure, which is adapted to the shape of the two transformer skeletons connected on one side after folding, and can be used to fix the position of the transformer skeleton, which is convenient for matching with the transformer winding machine processing.

[0044] In a preferred embodiment, the transverse groove 1113 is a waist-shaped groove. Specifically, two transformer frames connected on one side are folded and placed in the loading trough 111, and the overlapping parts correspond to the positions of the transverse grooves 1113. Since the overlapping parts may need to be adjusted, the transverse grooves 1113 are set as waist-shaped grooves to facilitate position adjustment.

[0045] like Figure 1 and Figure 4 As shown, in this embodiment, a threaded hole (not shown in the figure) is provided on the base plate 10, and a countersunk hole 115 corresponding to the threaded hole is provided on the positioning seat 11. The positioning seat 11 is installed on the base plate 10 by a countersunk bolt 1151.

[0046] Specifically, the positioning seat 11 is fixedly installed on the base plate 10 by passing the countersunk bolt 1151 through the threaded hole and the countersunk hole 115. The countersunk bolt 1151 can be sunk into the countersunk hole 115 to ensure that the surface of the connection part is flat to avoid collision with the transformer frame and damage to the transformer frame.

[0047] In a preferred embodiment, the countersunk hole 115 is provided in a waist-shaped structure, which facilitates adjusting the position of the positioning seat 11 installed on the base plate 10 to achieve precise positioning.

[0048] In a preferred embodiment, a plurality of positioning seats 11 are provided, and the plurality of positioning seats 11 are arranged side by side on the bottom plate 10. Specifically, the positioning seats 11 correspond to the number and position of the winding shafts of the transformer winding machine, and a plurality of positioning seats 11 can be provided to realize batch processing and improve production efficiency.

[0049] In a preferred embodiment, the plurality of positioning seats 11 are integrally formed and are firm and not easily damaged.

[0050] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a plurality of fixing holes 101 are provided on the bottom plate 10. Specifically, the fixing holes 101 are used to fix the bottom plate 10 to ensure that the position of the transformer winding tool is stable during operation and is not prone to displacement.

[0051] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a chamfer structure 1123 is provided at the top edge of the upper material trough 111 and the lower material trough 112. The chamfer structure 1123 can remove burrs on the top edge of the upper material trough 111 and the lower material trough 112 caused by machining, and passivate the edges to avoid scratching personnel when taking and placing the transformer frame, thereby ensuring safety in use.

[0052] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
