Description

Technical Field

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

[0002] The toroidal winding machine is a special equipment used to produce toroidal coils such as toroidal transformers, current transformers, and magnetic toroidal inductors. For example, the patent with announcement number CN207233572U discloses a transformer winding device, including a motor, a rotating rod, a positioning assembly and a winding rod. The motor rotating shaft is upwardly arranged on the bottom plate, and the rotating shaft of the motor is connected to the rotating rod. The winding rod is detachably arranged on the top of the rotating rod. The positioning assembly includes a positioning bracket, and a positioning base is provided on the positioning bracket. The positioning base is arranged corresponding to the winding rod, and an adjusting pressure plate is provided on the positioning base corresponding to the winding rod to limit the upward and downward movement of the transformer skeleton sleeved on the winding rod. The device drives the coil frame to rotate through a motor, so that it can efficiently wind the wire. An adjusting pressure plate is provided to prevent the coil frame from moving. The transformer winding device is easy to operate. However, during the winding process, the copper wire will be wound around the same position of the coil frame, which will cause uneven winding. This will make the electromagnetic induction capacity of the transformer fail to meet the transformer standard, thereby affecting the winding quality of the transformer, and the winding tension cannot be adjusted. If the winding is relatively loose, the coil is likely to fall off or loosen later, thereby causing damage to the transformer.

[0003] To this end, the utility model provides a toroidal transformer winding device. Utility Model Content

[0022] In this embodiment, a placement groove 2 is provided in the support frame 1 , and the placement groove 2 corresponds to the rotating shaft 3 . Both ends of the rotating shaft 3 are sleeved with anti-slip sleeves 4 .

[0023] The friction of the rotating shaft 3 can be increased by sleeve-mounting the anti-slip sleeve 4, thereby increasing the difficulty of rotating the rotating shaft 3, and thus increasing the tension on the copper wire 20, ensuring that the copper wire 20 can be tightly wound around the circumference of the toroidal transformer 22.

[0024] The positioning block 7 is fixedly connected to the mounting frame 5 by bolts. A through slot 8 is provided in the positioning block 7 , and the through slot 8 corresponds to the copper wire 20 .

[0025] Specifically, after the copper wire 20 is pulled out, it passes through the pulley 6 and then through the through slot 8 , so that the copper wire 20 can be vertically upward, thereby being conveniently wound on the toroidal transformer 22 . The pulley 6 can reduce the friction on the copper wire 20 .

[0026] A motor 9 is fixed to one side of the support frame 1, and the output end of the motor 9 is fixedly connected to one end of the reciprocating screw 11, a limit plate 19 is fixed between the reciprocating screw 11 and the sliding rod 21, a toroidal transformer 22 is installed on the sliding rod 21, and anti-slip grooves are provided on the circumference of the sliding rod 21, a fixing plate 13 is installed at one end of the sliding rod 21, an insert block 12 is fixed on the fixing plate 13, a slot is opened in the sliding rod 21, and the slot is threadedly matched with the insert block 12, a plurality of springs 15 are fixed between the fixing plate 13 and the pressure plate 14, a slide plate 17 is threadedly matched with the reciprocating screw 11, a plurality of connecting rods 18 are installed between the push plate 16 and the slide plate 17, the connecting rods 18 are rotatably connected to the slide plate 17, a plurality of sliding shafts 10 are fixed to the side of the slide plate 17 away from the push plate 16, and the sliding shafts 10 are slidably matched with the support frame 1.

[0027] Specifically, when the copper wire 20 needs to be wound around the toroidal transformer 22, the fixing plate 13 is rotated to separate the plug block 12 from the slot, and the toroidal transformer 22 can be sleeved on the slide bar 21, and then the fixing plate 13 is installed, so that the spring 15 pushes the pressure plate 14, and the pressure plate 14 squeezes and pushes the toroidal transformer 22. The toroidal transformer 22 is clamped and fixed by the pressure plate 14 and the limit plate 19, and then the slide plate 17 is rotated to make the slide plate 17 slide, and the slide plate 17 drives the push plate 16 to slide until the push plate 16 contacts the toroidal transformer 22, fixes one end of the copper wire 20 to the toroidal transformer 22, and then starts the motor 9, so that the motor 9 drives the reciprocating screw 11 to rotate, thereby driving the slide bar 21 to rotate, and the slide bar 21 drives the toroidal transformer 22 to rotate. At the same time, the push plate 16 pushes the toroidal transformer 22 to move, and the copper wire 20 can be evenly wound around the toroidal transformer 22.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
