Description

Technical Field

[0001] The utility model relates to the technical field of transformer processing equipment, in particular to a copper wire protective cover for transformer skeleton processing. Background Art

[0002] The toroidal transformer is a common electrical component. Its main components are coils and iron cores. During the transformer production process, a winding machine is needed to wind the transformer frame. The wire of the winding machine is generally copper wire. Multiple sets of copper wire reels are set behind the winding machine to input copper wire into the winding machine. In order to protect the copper wire and avoid copper wire entanglement, each copper wire reel needs to be placed in a separate protective cover.

[0003] When the copper coil is placed inside the protective cover, the copper wire is prone to shaking when it rotates inside the protective cover during the process of the winding machine pulling out the copper wire, resulting in an uneven wire output process. The stress between the copper wire output through the top outlet of the protective cover and the protective cover shell will also cause uneven wire output, making the copper wire output uneven, thereby affecting the winding effect of the front-end winding machine on the surface of the skeleton, resulting in uneven winding density and even winding failure.

A copper wire protective cover for transformer skeleton processing is proposed to solve the problem that when the copper coil is placed inside the protective cover, the copper wire is prone to shaking when it rotates inside the protective cover during the process of the winding machine pulling out the copper wire, resulting in an uneven wire output process, and even winding failure.

A sector piece 24 is fixedly connected to one end of the shaft 4. By setting a positioning device 2, when using the protective cover, the copper coil tube is sleeved from one end of the screw 25 onto the outer surface of the rotating shaft 4, and then the screw 25 is rotated to control the screw 25 to move along the inner wall of the rotating shaft 4 toward the rotating shaft 4, and the depth of the tapered rod 26 penetrating into the circular groove 21 is adjusted so that the tapered rod 26 pushes the sliding rod 22 to move outward and compresses the spring 23 to press the sector piece 24 against the inner wall of the copper coil tube. When the copper wire is pulled by the winding machine, the copper coil tube will rotate on the outer surface of each sector piece 24, and the angle between the copper coil tube and the rotating shaft 4 is further limited by the sector piece 24, so as to avoid shaking of the copper coil tube when it rotates as much as possible, thereby affecting the winding effect of the copper wire on the skeleton.

When the copper wire is output at one side of the protective cover body 1, one end of the copper wire can be passed through between the L-shaped block 27 and the positioning block 28, so that the copper wire passes between the L-shaped block 27 and the positioning block 28. The movement angle and position of the copper wire can be further restricted, and the movement path of the copper wire can be avoided as much as possible when the copper wire is pulled. Changes in the winding effect of the copper wire on the skeleton are avoided. One side of the inner wall of the L-shaped block 27 is rotatably connected with a groove ring 29, and a groove is provided on the outer surface of the groove ring 29. When the copper wire passes between the L-shaped block 27 and the positioning block 28, the movement of the copper wire can be further restricted by the groove on the outer surface of the groove ring 29, thereby increasing the stability of the copper wire when it leaves the surface of the copper coil tube.

[0031] Reference Figure 2-5 As shown, in this embodiment: one side of the L-shaped block 27 is rotatably connected to the first bolt 210, and one side of the positioning block 28 is fixedly connected to the threaded ring 211, and the inner wall of the threaded ring 211 is threadedly connected to the outer surface of the first bolt 210. Rotating the first bolt 210 can make the threaded ring 211 move on the outer surface of the first bolt 210 to control the positioning block 28 to slide on the outer surface of the L-shaped block 27. Adjusting the distance between the L-shaped block 27 and the positioning block 28 is convenient for limiting the position of copper wires of different thicknesses. One end of the screw rod 25 away from the tapered rod 26 is fixedly connected to a cylindrical block 212, and the outer surface of the cylindrical block 212 is fixedly connected to a plurality of protrusions. Holding the protrusions on the outer surface of the cylindrical block 212 and rotating the cylindrical block 212 can more conveniently control the rotation of the screw rod 25 without slipping.

[0032] Reference Figure 1-2 As shown, in the present embodiment: one side of the support rod 5 is rotatably connected with the mounting seat 6, one side of the support rod 5 is provided with an adjusting device 3, the adjusting device 3 comprises a groove plate 31, one side of the groove plate 31 is fixedly connected with one side of the mounting seat 6, a plurality of positioning holes 32 are provided on the outer surface of the groove plate 31, one end of the support rod 5 is fixedly connected with a protrusion 33, the inner wall of the protrusion 33 is threadedly connected with a second bolt 34, when the support rod 5 and the protective cover body 1 are installed on one side of the winding machine through the mounting seat 6, the support rod 5 can be pushed to rotate on one side of the mounting seat 6 to adjust the angle between the support rod 5, the mounting seat 6 and the winding machine, after the adjustment is completed, the second bolt 34 is rotated to make the second bolt 34 move on the inner wall of the protrusion 33 and insert one end into the positioning hole 32 on the outer surface of the groove plate 31, so as to fix the relative position and angle between the support rod 5 and the mounting seat 6.

[0033] Reference Figure 1-2As shown, in the present embodiment: one end of the second bolt 34 is fixedly connected with a round block 35, and the round block 35 is made of rubber material. When one end of the second bolt 34 provided with the rubber round block 35 is inserted into the interior of the positioning hole 32, the contact with the inner wall of the positioning hole 32 is tighter, and the position fixation between the support rod 5 and the mounting seat 6 is more stable. One side of the support rod 5 is fixedly connected with a fan-shaped block 36, and one side of the fan-shaped block 36 slides on one side of the groove plate 31. When the support rod 5 is pushed to rotate to adjust the angle between the support rod 5 and the mounting seat 6, one side of the fan-shaped block 36 will slide on one side of the groove plate 31, further limiting the angle between the support rod 5 and the mounting seat 6, and avoiding shaking of the support rod 5 during rotation and after fixing as much as possible.

[0034] Working principle: When winding the skeleton, first clamp the mounting seat 6 on one side of the support rod 5 on the winding machine or the frame rod on one side of the winding machine, and connect the mounting seat 6 to the frame rod through tools such as bolts. After the connection is completed, the support rod 5 can be pushed to rotate on one side of the mounting seat 6 to adjust the angle between the support rod 5 and the protective cover body 1 and the winding machine. After the adjustment is completed, rotate the second bolt 34 to make the second bolt 34 move on the inner wall of the protrusion 33, and clamp the rubber round block 35 at one end into the inside of the positioning hole 32 to fix the angle between the support rod 5 and the mounting seat 6, and then put the copper coil tube sleeve from one end of the screw rod 25 on the outer surface of the rotating shaft 4, and then rotate the screw 25 to control the screw 25 to move on the inner wall of the rotating shaft 4 toward the rotating shaft 4, and adjust the tapered rod 26 to go deep into the circular groove 21, so that the tapered rod 26 pushes the sliding rod 22 to move outward and compresses the spring 23 to press the sector piece 24 against the inner wall of the copper coil barrel, and then one end of the copper wire is passed through between the L-shaped block 27 and the positioning block 28, and the first bolt 210 is rotated to make the threaded ring 211 move on the outer surface of the first bolt 210 to adjust the position of the positioning block 28, so that the copper wire is located between the positioning block 28 and the groove on the outer surface of the groove ring 29. When the copper wire is pulled by the winding machine, the copper coil barrel will rotate on the outer surface of each sector piece 24, and the angle between the copper coil barrel and the rotating shaft 4 will be further restricted by the sector piece 24. After the copper wire is output, it will pass between the groove ring 29 and the positioning block 28 to further restrict the moving path of the copper wire, so as to avoid accidents in winding as much as possible.
