Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, specifically to a voltage regulating line mold. Background Technology

[0002] In transformer manufacturing, the voltage regulating coil, as a key component for voltage regulation, directly affects the transformer's electrical performance and operational stability due to its winding quality. Voltage regulating coils are typically wound from copper or aluminum wire (such as enameled wire or bare copper wire), and the output voltage is adjusted by changing the number of turns or the connection method. They are widely used in distribution transformers, power transformers, and on-load tap changers. Our previously filed patent for a voltage regulating die allows for the winding of coils with different numbers of turns by changing the die's diameter. However, in practice, it was found that each adjustment of the die's diameter requires manual measurement, which is time-consuming and impacts production efficiency.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0008] Furthermore, the voltage regulating die also includes a drive assembly, which is disposed inside the winding drum. The drive assembly is used to drive the first slider and the second slider to move closer to or further away from each other.

[0009] Furthermore, a rotation space is provided inside the winding drum, the rotation space extending along the extension direction of the winding drum, and the driving component includes: a first moving member, at least a portion of which is located within the rotation space and is movably disposed along the extension direction of the rotation space, and the first moving member protrudes from the rotation space and is connected to a first sliding member; a second moving member, at least a portion of which is located within the rotation space and is movably disposed along the extension direction of the rotation space, and the second moving member protrudes from the rotation space and is connected to a second sliding member, the second moving member and the first moving member being disposed close to or far from each other.

[0012] Furthermore, the second movable member is provided with a second connecting protrusion, which is movably disposed in the limiting slide groove and is connected to the second movable member.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] According to an embodiment of this utility model, a voltage regulating line mold is provided. Please refer to [link / reference]. Figures 1 to 2It includes: a line mold body 1, which has a fixed part and a movable part, the movable part being movably disposed relative to the fixed part; a distance measuring element, the transmitting end of the distance measuring element being mounted on the movable part, the receiving end of the distance measuring element being mounted on the fixed part, and the distance measuring element being used to measure the distance between the fixed part and the movable part.

[0020] By adopting the above technical solution, the alignment installation scheme of fixing the transmitter of the ranging device to the winding plate 3 of the movable part and fixing the receiver to the winding drum 2 of the fixed part achieves the effect of real-time automatic feedback of winding radius change data, completely replacing manual measurement operation, significantly shortening the mold adjustment time and eliminating human measurement error.

[0021] Please refer to Figure 2 The wire mold body 1 includes: a winding drum 2, which extends along a preset direction; a plurality of winding plates 3, which are arranged around the winding drum 2 in the circumferential direction, and the plurality of winding plates 3 form a winding area for positioning the coil; each winding plate 3 is movably arranged relative to the winding drum 2 so as to adjust the size of the winding area when each winding plate 3 moves closer to or further away from the winding drum 2.

[0022] The transmitter of the ranging device is mounted on one of the winding plates 3, and the receiver of the ranging device is mounted on the winding drum 2. The transmitter of the ranging device is positioned facing the receiver of the ranging device. Furthermore, the ranging device is a ranging sensor or an infrared rangefinder. The ranging sensor is connected to an external display device through a controller to view the distance between the winding plate 3 and the winding drum 2, i.e., the real-time radius of the wound coil.

[0023] By adopting the above technical solution, an adjustable winding area is formed by multiple winding plates 3 surrounding the winding drum 2 in a circumferential manner, and each winding plate 3 moves radially closer to or further away from the winding drum 2 at the same time, the effect of continuously stepless adjustment of the coil diameter is achieved, ensuring that the inter-turn gap is evenly distributed during the coil winding process and improving the consistency of the coil structure.

[0024] Please refer to Figure 1The wire mold body 1 further includes: a first sliding member 4, which is movably sleeved on the winding drum 2 along the extension direction of the winding drum 2; a plurality of first transmission rods 6, which are arranged around the first sliding member 4 in the circumferential direction, and are arranged one-to-one with a plurality of winding plates 3, and each first transmission rod 6 is hinged to the first sliding member 4 and the corresponding winding plate 3 respectively; a second sliding member 5, which is movably sleeved on the winding drum 2 along the extension direction of the winding drum 2; the second sliding member 5 is spaced apart from the first sliding member 4 so that when adjusting the size of the winding area, the second sliding member 5 and the first sliding member 4 move closer or further apart from each other; and a plurality of second transmission rods 7, which are arranged around the second sliding member 5 in the circumferential direction of the second sliding member 5, and are arranged one-to-one with a plurality of winding plates 3, and each first transmission rod 6 is hinged to the first sliding member 4 and the corresponding winding plate 3 respectively.

[0025] When the first sliding member 4 and the second sliding member 5 move closer or further apart, the first sliding member 4 drives the winding plates 3 to move closer or further apart through the first transmission rods 6 and the second sliding member 5 drives the winding plates 3 to move closer or further apart through the second transmission rods 7, so as to adjust the size of the winding area.

[0026] By adopting the above technical solution, through the bidirectional linkage scheme of the first sliding member 4 being hinged to the corresponding winding plate 3 via multiple first transmission rods 6 and the second sliding member 5 being hinged to the corresponding winding plate 3 via multiple second transmission rods 7, the axial linear motion of the first sliding member 4 and the second sliding member 5 is efficiently converted into the synchronous radial displacement of the winding plate 3, thereby achieving precise coordinated control of the motion trajectory of the winding plate 3 group.

[0027] The winding drum 2 forms a fixed part, while the winding plates 3, the first sliding member 4, the second sliding member 5, the first transmission rod 6, and the second transmission rod 7 form a movable part.

[0028] Furthermore, the winding drum 2 is provided with a first limiting protrusion 8 and a second limiting protrusion 9. Both the first limiting protrusion 8 and the second limiting protrusion 9 extend along the extension direction of the winding drum 2. The first limiting protrusion 8 and the second limiting protrusion 9 are spaced apart along the extension direction of the winding drum 2. The first sliding member 4 is movably disposed on the first limiting protrusion 8 along the extension direction of the first limiting protrusion 8. The second sliding member 5 is movably disposed on the second limiting protrusion 9 along the extension direction of the second limiting protrusion 9.

[0029] By adopting the above technical solution, and by setting a first limiting protrusion 8 extending axially on the winding drum 2 to constrain the first sliding member 4 and a second limiting protrusion 9 to constrain the second sliding member 5, the effect of forcibly restricting the sliding members 4 and 5 to move only along the axial direction of the winding drum 2 is achieved, eliminating the risk of radial offset and ensuring the motion stability of the transmission mechanism.

[0030] Please refer to Figure 1 The voltage regulating die also includes a drive assembly 10, which is disposed inside the winding drum 2. The drive assembly 10 is used to drive the first sliding member 4 and the second sliding member 5 to move closer to or further away from each other.

[0031] By adopting the above technical solution, the integrated solution of embedding the drive component 10 in the rotation space of the winding drum 2 and directly connecting the first sliding member 4 and the second sliding member 5 achieves the effect of providing driving force in a centralized manner and avoiding interference from external mechanisms in the coil winding operation, thus optimizing the spatial layout of the equipment.

[0032] Please refer to Figure 2 The winding drum 2 has a rotation space that extends along the extension direction of the winding drum 2. The drive assembly 10 includes: a first moving member 12, at least a portion of which is located within the rotation space and is movably disposed along the extension direction of the rotation space, and the first moving member 12 protrudes from the rotation space and is connected to the first sliding member 4; and a second moving member 13, at least a portion of which is located within the rotation space and is movably disposed along the extension direction of the rotation space, and the second moving member 13 protrudes from the rotation space and is connected to the second sliding member 5. The second moving member 13 and the first moving member 12 are disposed close to or far from each other.

[0033] By adopting the above technical solution, and through the sealed design of the first moving part 12 nested in the rotation space and externally connected to the first sliding part 4, and the second moving part 13 nested in and externally connected to the second sliding part 5, the effect of isolating metal dust from entering the drive mechanism during the winding operation is achieved, extending the service life of the equipment, and at the same time realizing the efficient transmission of axial driving force.

[0034] Please refer to Figure 2 The drive assembly 10 further includes a bidirectional lead screw 11, which is rotatably disposed in the rotation space. The bidirectional lead screw 11 includes a left thread section and a right thread section with opposite directions of rotation. The left thread section and the right thread section are respectively threaded with the first moving member 12 and the second moving member 13 to drive the first moving member 12 and the second moving member 13 to move closer to or further away from each other.

[0035] By adopting the above technical solution, the reverse thread transmission scheme of driving the first moving part 12 with the left thread section of the bidirectional lead screw 11 and driving the second moving part 13 with the right thread section achieves the effect of synchronously controlling the precise reverse movement of the first moving part 12 and the second moving part 13 with a single input shaft rotation, ensuring the geometric accuracy of the symmetrical expansion or contraction of the winding plate 3 groups.

[0036] Please refer to Figure 2The winding drum 2 is provided with a limiting groove, which extends along the extension direction of the winding drum 2; the first moving part 12 is provided with a first connecting protrusion 14, which is movably disposed in the limiting groove and is connected to the first moving part 12.

[0037] By adopting the above technical solution, and by setting the first connecting protrusion 14 on the first moving part 12 to be embedded in the limiting groove of the winding cylinder 2 to prevent rotation, the effect of constraining the circumferential rotational freedom of the first moving part 12 and transmitting the axial driving force in a directional manner is achieved, thus ensuring the accuracy of the linear motion trajectory of the first sliding part 4.

[0038] Please refer to Figure 2 The second movable member 13 is provided with a second connecting protrusion 15, which is movably disposed in the limiting slide groove and is connected to the second movable member 13.

[0039] By adopting the above technical solution, and by setting a second connecting protrusion 15 on the second moving part 13 and embedding it into the same limiting groove, the effect of synchronously constraining the movement trajectory of the second moving part 13 is achieved, maintaining the coaxiality of the movement axes of the first moving part 12 and the second moving part 13, and avoiding mechanism jamming.

[0040] Working principle: When the operator inputs the target coil diameter command through an external control device, the controller automatically calculates the corresponding target radial displacement of the winding plate 3 and activates the drive assembly 10 built into the winding drum 2. At this time, the bidirectional lead screw 11 rotates, with its left threaded section driving the first moving member 12 and its right threaded section driving the second moving member 13 to move in opposite directions (the first moving member 12 pushes the first sliding member 4 to move axially along the first limiting protrusion 8 via the first connecting protrusion 14, and the second moving member 13 pushes the second sliding member 5 to move axially along the second limiting protrusion 9 via the second connecting protrusion 15), causing the first sliding member 4 and the second sliding member 5 to move towards or away from each other. The winding plate 3 is moved radially towards or away from the winding drum 2 by multiple first transmission rods 6 hinged by the first sliding member 4 and multiple second transmission rods 7 hinged by the second sliding member 5, thereby achieving stepless adjustment of the winding area. At the same time, the transmitter of the ranging device installed on the winding plate 3 sends a signal to the receiver on the winding drum 2 in real time. The controller continuously acquires the real-time distance data between the winding plate 3 and the winding drum 2 and compares it with the target value. If the error exceeds the threshold, the rotation angle of the bidirectional lead screw 11 is finely adjusted until the feedback value of the ranging device meets the target range and then the drive stops. Finally, the coil winding is completed on the winding plate 3 group with the calibrated diameter.
