Description

Technical Field

[0001] The utility model relates to a coil winding and tensioning device, in particular to a high-frequency transformer coil winding and tensioning device, belonging to the technical field of transformer coil winding equipment. Background Art

[0002] A high-frequency transformer is a transformer with an operating frequency exceeding 10kHz, which is composed of a ferrite core and an enameled wire coil. In the Chinese patent authorization announcement number CN211366528U, a transformer coil winding device is disclosed, which facilitates the user to wind the wire through the setting of a rotating mechanism and a second rotating shaft, and facilitates the user to move the drum through the cooperation of a moving mechanism. The drum moves left and right while rotating, which facilitates the user to wind the wire and prevent the wire from being entangled and affecting the winding. Through the cooperation of a semicircular baffle, it is convenient for the user to comb the wire and prevent the wire from being entangled during the winding process, solving the problem that the traditional transformer coil winding device cannot wind autonomously.

[0003] The above transformer coil winding device winds the enameled wire on the drum. During the winding process, when the winding speed slows down, it is easy to cause the enameled wire between the outer coil roll and the drum to loosen, and it does not have the function of tightening the enameled wire, which seriously affects the winding effect of the transformer coil. In addition, combined with the existing transformer coil winding device with the function of tightening the enameled wire, the coil roll of the rolled enameled wire needs to be assembled on the winding device. Because a certain rotation damping is required between the coil roll assembly column of the winding device and the coil roll, it is not convenient to install the coil roll on the coil roll assembly column of the winding device; moreover, when the coil roll is subjected to excessive tension of the enameled wire, the enameled wire is easily broken due to the excessive tension.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment of the utility model provides a high-frequency transformer coil winding and tensioning device.

[0027] The utility model comprises a base 1, and two symmetrical sets 2 are arranged on the top of the base 1, and the sets 2 comprise a fixed cylinder 201 and four arc-shaped plates 209, and the inner wall of the fixed cylinder 201 is slidably connected with a movable block 1 202, and the outer surface of the movable block 1 202 is fixedly connected with a movable block 203, and the outer surface of the movable block 203 is fixedly connected with a spring 204, and the outer surface of the movable block 203 is fixedly connected with a symmetrical handle 205, and the shape of the handle 205 is Z-shaped, and the movable block 203 can be moved more conveniently by arranging the handle 205.

[0028] The coil roll 10 of the transformer coil winding device is mounted on the tensioning device through two mounting parts 2 (please refer to Figure 2 ).

[0029] A group of connecting rods 1 206 are fixedly connected to the outer surface of the movable block 1 202 , and one end of each connecting rod 1 206 is hinged to a connecting rod 2 207 . One end of the fixed cylinder 201 is fixedly connected to a fixed column 208 , and the connecting rod 207 is hinged to the inner wall of the arc plate 209 .

[0030] The inner wall of each arc plate 209 is hinged with a connecting rod three 211, the outer surface of the fixed column 208 is fixedly connected with a group of connecting rods four 212, and the inner wall of each arc plate 209 is fixedly connected with a limiting plate 210, and the minimum spacing between the four arc plates 209 is limited by the setting of the limiting plate 210.

[0031] The above-mentioned connecting rod three 211 is hinged with the connecting rod four 212, and the spring 204 is located inside the fixing tube 201, and the spring 204 plays a role in resetting the connecting rod one 206.

[0032] The two handles 205 extend to the outside of the fixed tube 201 and are slidably connected to the fixed tube 201 . Each connecting rod 206 extends to the outside of the fixed tube 201 and is slidably connected to the fixed tube 201 .

[0033] Please refer to Figure 2 , Figure 3 and Figure 4 In the above scheme, by pushing the handle 205 left or right to move the connecting rod 1 206 left or right, the angle between the connecting rod 207 and the connecting rod 3 211 can be changed, so that the spacing between the four arc plates 209 can be adjusted, so that the four arc plates 209 can expand or contract about the fixed column 208.

[0034] The upper surface of the base 1 is fixedly connected with a fixing plate 1 3 and a fixing plate 2 7 , the middle of the fixing plate 1 3 is fixedly inlaid with an electric push rod 4 , and the middle of the fixing plate 2 7 is fixedly installed with a servo motor 8 .

[0035] Among them, the telescopic ends of the two electric push rods 4 are rotatably connected to the fixed disk 1 5, the output shaft of the servo motor 8 is fixedly connected to the fixed disk 2 9, and the fixed disk 1 5 and the fixed disk 2 9 are respectively fixedly connected to the fixed cylinders 201 in the two sets 2.

[0036] In the above solution, the servo motor 8 is used to drive one of the assembly components 2 to rotate, and the electric push rod 4 is used to adjust the horizontal position of the other assembly component 2.

[0037] The bottom surface of the base 1 is fixedly connected with symmetrical support frames 6, and the two support frames 6 can be clamped on the transformer coil winding device so that the tensioning device is fixed on the transformer coil winding device.

[0038] When the utility model is in use: firstly, the electric push rod 4 is started to shorten the electric push rod 4, and then the coil roll 10 is placed between the two sets 2, and then the handle 205 in one of the sets 2 is pulled to compress the spring 204, and at the same time, the connecting rod 1 206 moves away from the fixed column 208, and the angle between the connecting rod 207 and the connecting rod 3 211 becomes larger, and the four arc plates 209 contract about the fixed column 208, and then the set 2 is inserted into the middle hole of the coil roll 10, and then the handle 205 is released, and under the elastic action of the spring 204, the connecting rod 1 206 can move in the direction of the fixed column 208, and the angle between the connecting rod 207 and the connecting rod 3 211 becomes smaller, so that the four arc plates 209 can expand about the fixed column 208, until the arc plates 209 are close to the middle hole wall of the coil roll 10, and the coil roll 10 can be fixedly sleeved on one of the sets 2;

[0039] Then, the electric push rod 4 is started to extend, and the handle 205 in the other set 2 is pulled in the direction of the fixed plate 1 3 to compress the spring 204. At the same time, the connecting rod 1 206 moves away from the fixed column 208, and the angle between the connecting rod 207 and the connecting rod 3 211 becomes larger, and the four arc plates 209 contract about the fixed column 208. When the electric push rod 4 extends, the set 2 is inserted into the middle hole of the coil roll 10, and then the handle 205 is released. Under the elastic action of the spring 204, the connecting rod 1 206 can move in the direction of the fixed column 208, and the angle between the connecting rod 207 and the connecting rod 3 211 becomes smaller, so that the four arc plates 209 can expand about the fixed column 208 until the arc plates 209 are close to the middle hole wall of the coil roll 10, so that the coil roll 10 is fixedly sleeved on the other set 2. In summary, the coil roll 10 can be quickly and conveniently sleeved on the device.

[0040] Then, one end of the enameled wire on the coil roll 10 is connected to the transformer winding device to perform the winding operation. During the winding operation, the two sets 2 and the coil roll 10 are rotated synchronously by starting the servo motor 8 to provide the coil roll 10 with a reverse rotational force, thereby tightening the loose enameled wire, so that the transformer winding device can keep the enameled wire in a taut state during the winding operation, thereby improving the winding effect of the transformer coil. In addition, because the middle hole of the coil roll 10 is mounted on the device through the set 2, the four arc plates 209 are tightly attached to the middle hole wall of the coil roll 10 under the elastic action of the spring 204, but are not completely fixed thereto. Therefore, when the coil roll 10 is subjected to excessive tension from the enameled wire, the coil roll 10 slips on the surface of the four arc plates 209, which can avoid the enameled wire from being broken due to excessive tension, thereby improving the tensioning effect of the enameled wire.
