Description

Technical Field

[0001] The invention relates to the technical field of transformer manufacturing, and in particular to a winding device for transformer flying wires. Background Art

[0002] Transformer winding machine is a special equipment used to wind transformer coils. In the transformer coil production process, winding equipment is divided according to the transformer voltage level or capacity. There are automatic wire winding machines and foil coil winding machines for winding high and low voltage coils of distribution transformers; there are vertical winding machines and horizontal winding machines for winding large power transformer coils.

[0003] Generally, a small transformer includes an inner frame, a coil and an iron core, the coil is wound on the inner frame, the inner frame includes a center hole, and the iron core is installed in the center hole. The manufacturing process of the small transformer is to first insert the inner frame into the winding shaft on the transformer winding machine, and then continuously wind the coil onto the inner frame.

[0004] Generally, the wires are twisted manually, but manual twisting is not only labor-intensive, but also inefficient; therefore, a special jig for twisting transformer wires with flying wires is developed, as described in Chinese patent CN201220216100.4, which includes an upper clamp and a lower clamp, one end of which is provided with a connecting shaft, and the upper clamp is fixedly connected to the lower clamp by a movable pin, and a spring is also provided between the top of the upper clamp and the lower clamp, and the flying wire is placed in the interface of the upper and lower clamps, and then the rotating motor is turned on to drive the jig to rotate, so that the flying wire can be twisted. However, when the flying wire is fixed between the upper and lower clamps, the tail end of the upper clamp needs to be pressed downward first, and under the action of the spring, the head of the upper clamp opens, so that the flying wire can be placed in the interface. This operation method has low work efficiency, and at the same time, it is easy to injure the hand when touching the rotating upper clamp by hand, which brings safety hazards. Summary of the invention

[0005] The present invention aims to provide a winding device for transformer flying leads, so as to solve the problem in the prior art that the flying lead head needs to be manually fixed before winding during the winding process.

[0006] The transmission gear of claim 1, wherein the first and second gears are connected along the longitudinal axis of the wheel shaft and the second and third gears are engaged with the first and second gears of the vehicle frame, and the transmission gears are connected along the longitudinal axis of the wheel shaft to the rotationally connected wheel shaft. The wall is vertically provided with a slide groove, the positioning rod is slidably arranged in the slide groove, and a partition is provided on the slide rod, and the partition divides the slide rod into a smooth part and a meshing part located below the smooth part, and the upper surface of the smooth part is provided with a groove, and the groove passes through from one side of the upper surface of the smooth part to the other side, and the two sides of the meshing part are respectively meshed with the driving wheel and the driven wheel; the winding device includes an annular tube and a winding disk, and the winding disk includes a winding rod and two circular blocking plates, and the blocking plates are meshed with the inner wall of the annular tube, and the winding rod is connected to a first motor for driving the winding disk to rotate; a fixing frame is fixedly provided on the upper surface of the fixing plate, and a telescopic rod is fixed on the fixing frame, and the telescopic rod and the slide rod are located on the same central axis, and an extrusion block for extruding the groove is provided at an end of the telescopic rod away from the fixed frame; the driving shaft is connected to a second motor for driving the driving shaft to rotate.

[0007] The working principle and beneficial effects of this solution are as follows: when in use, the flying wire is wound around the outer wall of the winding rod, the transformer is placed on the smooth part of the slide rod, the partition plays a supporting role therefor, the flying wire is wound around the winding rod, the first motor is turned on, the winding disc is rotated until the flying wire head is placed in the groove, the second motor is turned on, the driving shaft starts to rotate, driving the driving wheel and the driving fan-shaped wheel to rotate, the driving wheel rotates forward to drive the transmission wheel to reverse, the transmission wheel reverses to drive the driven wheel to rotate forward, the driving fan-shaped wheel drives the slide rod meshing with it to move upward, and in the process of the slide rod moving upward, the groove contacts the extrusion block, the extrusion block squeezes the groove, so that the flying wire is fixed The wire is fixed in the groove. At this time, as the sliding rod moves upward, the winding drum continuously winds the transformer on the sliding rod. At the same time, the process of the sliding rod moving upward squeezes the telescopic rod to shorten. Because in the process of the sliding rod moving upward, the pressure block on the telescopic rod keeps squeezing the wire end of the flying wire, so that the flying wire will not fall out. Until the winding is completed, the first click and the second motor are turned off to cut the flying wire, and then the second motor is turned on. At this time, the driven fan wheel engages with the sliding rod to drive the sliding rod to move downward. After the sliding rod moves out of the annular pipe, the second motor is turned off to take out the transformer, and the winding is completed. Repeat the above steps to wind the next transformer. The device in this scheme can utilize the rise of the sliding rod so that the sliding rod is squeezed by the squeezing block, so that the flying wire head in the groove is fixed. Compared with the prior art, the device replaces human hands, making the working efficiency of the flying wire twisting higher, and the human hands do not contact the rotating shaft, making the operation safer and avoiding safety hazards. It is suitable for promotion and application.

[0008] Furthermore, a limiting plate is provided between the two blocking plates, and a limiting through hole is provided on the side wall of the limiting plate. The limiting plate can allow the flying wire to pass through the limiting through hole, and the limiting through hole can prevent the flying wire from moving during the rotation of the winding drum, resulting in uneven winding.

[0009] Furthermore, the contact surface between the extrusion block and the groove is provided with anti-skid protrusions, so as to make the flying wire in the groove and the extrusion block more stable and ensure the winding effect.

[0010] Furthermore, a limiting ring is provided on the lower surface of the meshing portion, which can prevent the slide bar from being separated from the active sector wheel due to inertia when the slide bar rises under the action of the active sector wheel.

[0011] Furthermore, the partition is provided with a positioning groove, which can fix the wire in the positioning groove after the transformer winding is completed, so as to prevent the flying wire from moving around.

[0012] Furthermore, the smooth portion is made of magnets. When the transformer is placed on the slide bar, the smooth portion is made of magnets, so the transformer can be adsorbed, and the transformer will not fall if there is no external force. BRIEF DESCRIPTION OF THE DRAWINGS

A positioning groove 6 is provided on the partition 15. A groove 16 is provided on the upper surface of the smooth portion. The groove 16 runs from one side of the upper surface of the smooth portion to the other side. The two sides of the meshing portion are respectively meshed with the driving wheel 14 and the driven wheel 7. A limit ring 10 is provided on the lower surface of the meshing portion. The winding device includes an annular tube 2 and a winding drum 3. The winding drum 3 includes a winding rod and two circular blocking plates. The blocking plates are meshed with the inner wall of the annular tube 2. A limit ring 10 is provided between the two blocking plates. Plate 4, the side wall of the limiting plate 4 is provided with a limiting through hole, and the winding rod is connected to a first motor for driving the winding drum 3 to rotate; a fixing frame 1 is fixedly provided on the upper surface of the fixing plate 5, and a telescopic rod 18 is fixedly provided on the fixing frame 1, and the telescopic rod 18 and the sliding rod 11 are located on the same central axis, and an extrusion block 17 for extruding the groove 16 is provided at one end of the telescopic rod 18 away from the fixing frame 1, and an anti-slip convex point is provided on the contact surface of the extrusion block 17 and the groove 16; the driving shaft 13 is connected to a second motor for driving the driving shaft 13 to rotate.

[0017] When in use, the flying wire is wound around the outer wall of the winding rod, and the transformer is placed on the smooth part of the slide bar 11. When the transformer is placed on the smooth part, since the smooth part is made of magnets, the transformer can be adsorbed. In the absence of other external forces, the transformer will not fall. The partition 15 supports it. The flying wire is wound around the winding rod, and the first motor is turned on to rotate the winding drum 3 until the flying wire head is in the groove 16. The limiting through hole can prevent the flying wire from moving during the rotation of the winding drum 3, resulting in uneven winding. The second motor is turned on, and the driving shaft 13 starts to rotate, driving the driving wheel 14 and the driving sector wheel 12 to rotate. The driving wheel 14 rotates forward to drive the transmission wheel to reverse, and the transmission wheel reverses to drive the driven wheel 7 to rotate forward. The driving sector wheel 12 drives the slide bar 11 meshed with it to move up. During the upward movement of the slide bar 11, the groove 16 contacts the extrusion block 17, and the extrusion block 17 squeezes the groove 16, so that the flying wire is fixed in the groove 16, and the anti-slip protrusion makes the groove 16 and the anti-slip protrusion contact with the groove 16. The flying wire in the extrusion block 17 is more stable, ensuring the winding effect. At this time, as the sliding bar 11 moves upward, the winding drum 3 continuously winds the transformer on the sliding bar 11. At the same time, the process of the sliding bar 11 moving upward squeezes the telescopic rod 18 to shorten. Because in the process of the sliding bar 11 moving upward, the pressing block on the telescopic rod 18 keeps squeezing the wire end of the flying wire, so that the flying wire will not fall out. The limiting ring 10 can prevent the sliding bar 11 from rising under the action of the active fan wheel 12 and separating from the active fan wheel 12 under the action of inertia until the winding is completed. The positioning groove 6 can fix the wire in the positioning groove 6 after the transformer winding is completed to prevent the flying wire from moving anywhere, and then turn off the first motor and the second motor, cut the flying wire, and then turn on the second motor. At this time, the driven fan wheel 9 is engaged with the sliding bar 11, driving the sliding bar 11 to move downward. After the sliding bar 11 moves out of the annular pipeline, the second motor is turned off and the transformer is taken out, and the winding is completed. Repeat the above steps to wind the next transformer. The device in this scheme can utilize the rise of the slide bar 11 so that the slide bar 11 is squeezed by the squeezing block 17, so that the flying wire head in the groove 16 is fixed. Compared with the prior art, the device replaces human hands, making the flying wire twisting work more efficient, and the human hands do not contact the rotating shaft, making the operation safer and avoiding safety hazards, which is suitable for promotion and application.
