[0002] A metering transformer refers to a transformer used for precise metering of voltage, current, electric energy, etc. in a circuit for measurement purposes, and is a general term for a voltage transformer for measurement and a current transformer for measurement.

[0003] The inventor found that during the production and processing of existing metering transformers, it is necessary to wind and wrap an insulating cloth around the outer side of the ring inside the transformer. In the existing technology, equipment similar to a winding machine is used for winding. However, due to the too small diameter of the ring inside some transformers, the winding ring plate inside the winding machine has a large size and cannot directly pass through the ring. Therefore, for such small rings, manual wrapping and winding methods are used, resulting in low overall production and processing efficiency.

[0018] S2 simultaneously makes the connection between the first clamping mechanism and the winding ring plate fixed. Then, it controls the conveying mechanism to convey the end of the insulating cloth to the first clamping mechanism, so that the first clamping mechanism fixes the end of the insulating cloth. Then, it releases the fixing of the insulating cloth by the conveying mechanism, makes the conveying mechanism return to the initial position, and at the same time controls the winding ring plate to rotate.

[0019] S3 When the winding of the insulating cloth is completed, it controls the second clamping mechanism to be connected and fixed to the winding ring plate, and makes the second clamping mechanism clamp and fix the other end of the insulating cloth;

At this time, it can control the rotation of the winding ring plate and the driving roller, and control their rotation speeds, so that the insulating cloth is evenly wound around the outside of the transformer ring. During the rotation of the winding ring plate, the insulating cloth will sequentially squeeze the corresponding support rods. When the support rod is squeezed from one end to the other end by the insulating cloth, it makes the support rod contract into the slider. At this time, it can automatically switch to another support rod to support the insulating cloth, and the slider where the support rod contracts automatically moves back, returns to the initial position, and makes the support rod extend again to wait for the next support. Through the sequential switching mode of the support rods, during the winding process of the insulating cloth, the insulating cloth can always be kept in a tensioned state, so that the insulating cloth can be more closely attached and wound around the outside of the transformer ring;

[0021] S5 When the winding of the insulating cloth is completed, it controls the second clamping mechanism to release the fixing of the insulating cloth, and at the same time releases the fixing of the driving roller to the transformer ring. At this time, the transformer ring with the insulating cloth wound can be sent to the next production step.

[0022] Compared with the prior art, the present invention has the following technical effects:

[0023] The design of the winding ring plate, the support rod and the slider can make the support rod reciprocate through the reciprocating movement of the slider. Coupled with the expansion and contraction of the support rod, during the winding process of the insulating cloth, the insulating cloth can squeeze the support rod and the slider to move towards one end. When the support rod moves to the end, through the contraction of the support rod, the insulating cloth is automatically switched to another support rod for support, and the slider after the support rod contracts will automatically return to the initial position. At the same time, the support rod can also extend again to wait for the next support. Through the sequential switching mode of the support rods, during the winding process of the insulating cloth, the insulating cloth can always be kept in a tensioned state, so that the insulating cloth can be wound around the transformer ring better and tighter;

[0024] Moreover, with such a design, the insulating cloth is integrated in the winding ring plate, so that when winding some transformer rings with a smaller diameter, it can pass through better and wind the transformer ring better; it realizes mechanized winding and improves production efficiency.

[0025] The addition of the conveying mechanism, the first clamping mechanism and the second clamping mechanism makes the whole more intelligent, reduces manual operation and improves efficiency.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terms used herein in the description of the present invention are only for the purpose of describing specific implementation manners and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3 , a processing device for the production of metering transformers, used for winding insulating cloth on the transformer ring. It includes a processing base 1, on which there are two symmetrically distributed and synchronously rotatable winding ring plates 16. At the same position of the two winding ring plates 16, there are notch grooves for placing the transformer ring. On the processing base 1, there are multiple rotatable driving rollers for driving the transformer ring to rotate. On the inner side walls of the winding ring plates 16, there are multiple evenly distributed arc grooves 162, and the multiple arc grooves 162 form a circle. In each arc groove 162, there is a slidable block 1631 that can move back and forth in a matching manner. On the outer sides of the slidable blocks 1631, there are telescopic support rods 163. Between the winding ring plates 16 located in the inner ring, there is a detachable first clamping mechanism for clamping and fixing the insulating cloth. Above the winding ring plates 16, there is a rotatable and wound insulating cloth, and above the winding ring plates 16, there is a conveying mechanism 14 for conveying the insulating cloth into the first clamping mechanism. Between the winding ring plates 16 located in the outer ring, there is also a detachably connected second clamping mechanism for fixing the end of the insulating cloth.

[0042] The design of the winding ring plate 16, the support rod 163 and the slidable block 1631 enables the support rod 163 to reciprocate through the reciprocating movement of the slidable block 1631. Combined with the telescoping of the support rod 163, during the winding process of the insulating cloth, the insulating cloth can squeeze the support rod 163 and the slidable block 1631 to move towards one end. When the support rod 163 moves to the end, through the contraction of the support rod 163, the insulating cloth automatically switches to another support rod 163 for support. After the support rod 163 contracts, the slidable block 1631 will automatically return to the initial position, and at the same time, the support rod 163 can also extend again, waiting for the next support. Through the sequential switching mode of the support rod 163, the insulating cloth can always be kept in a tensioned state during the winding process, so that the insulating cloth can be wound on the transformer ring better and tighter;

[0043] Moreover, with such a design, the insulating cloth is integrated into the winding ring plate 16, making it possible to better pass through and wind the transformer ring when winding some transformer rings with a smaller diameter.

[0044] The addition of the conveying mechanism 14, the first clamping mechanism and the second clamping mechanism makes the whole more intelligent, reduces manual operation and improves efficiency.

[0045] In this embodiment, please refer to Figure 2 、 Figure 4, the cross-section of the arc-shaped groove 162 is convex, and a first spring 1637 for driving the slider 1631 to return to its initial position is provided in the arc-shaped groove 162. A first adjustment groove 1632 is provided on the outer side wall of the slider 1631, and the support rod 163 is slidably connected in the first adjustment groove 1632. A second spring 1633 for driving the support rod 163 to automatically pop out is provided in the first adjustment groove 1632. A through-type second adjustment groove 1638 is provided in the slider 1631 located in the arc-shaped groove 162. A push rod 1634 is slidably connected in the second adjustment groove 1638. The end of the push rod 1634 is connected to a first connecting piece 1635 that can be bent. The extended end of the first connecting piece 1635 movably passes through the first adjustment groove 1632 and is fixedly connected to the support rod 163. After the slider 1631 moves to one side, the push rod 1634 contacts and presses against the side wall of the arc-shaped groove 162, and drives the support rod 163 to automatically retract into the first adjustment groove 1632 through the transmission of the first connecting piece 1635.

[0046] The design of the first spring 1637 enables the insulating cloth to squeeze the first spring 1637 during the winding process, storing energy in the first spring 1637. The addition of the push rod 1634 and the first connecting piece 1635 enables the push rod 1634 to move in the second adjustment groove 1638 through the extrusion between the push rod 1634 and the inner wall of the arc-shaped groove 162 when the slider 1631 moves to the end, thereby realizing the automatic contraction of the support rod 163 through the first connecting piece 1635. The addition of the second spring 1633 enables the previous support rod 163 and the slider 1631 to move to the initial position under the release of the stored energy of the first spring 1637 when the insulating cloth switches to the next support rod 163 because there is no extrusion of the insulating cloth. The elasticity of the second spring 1633 can drive the support rod 163 to automatically extend. Such a design can realize the reciprocating movement of the slider 1631 and the support rod 163, as well as the telescopic control of the support rod 163.

[0047] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 , a winding groove 112 is provided on the processing base 1. Two fixedly connected fixing plates 11 are provided at the upper end of the winding groove 112. The winding ring plates 16 are respectively rotatably connected to the corresponding fixing plates 11. A plurality of rotatable winding rollers 111 for driving the two winding ring plates 16 to rotate synchronously are provided on both the fixing plates 11 and the winding groove 112. A winding motor for driving the winding roller 111 to rotate is provided on the fixing plate 11. The winding motor and the winding roller 111 can realize the synchronous rotation of the two winding ring plates 16. Among them, a winding ring groove for limiting the rotation of the winding ring plate 16 is provided on the fixing plate 11.

[0048] In this embodiment, please refer to Figure 3 and Figure 6 , a placing shaft 15 is provided on the fixing plate 11, the insulating cloth is placed in a wound state on the placing shaft 15, the fixing plate 11 is fixedly connected with a first hydraulic rod 141, the end of the first hydraulic rod 141 is connected to the conveying mechanism 14, the conveying mechanism 14 includes a conveying plate 142 and a pressing plate 144, the first hydraulic rod 141 is fixedly connected with the conveying plate 142, a plurality of second hydraulic rods 143 fixedly connected are provided on the conveying plate 142, and the end of the second hydraulic rod 143 is fixedly connected to the pressing plate 144. The addition of the first hydraulic rod 141 and the second hydraulic rod 143 realizes the conveying of the conveying plate 142 and the pressing and fixing of the end of the insulating cloth, so that the conveying mechanism 14 can fix and convey the insulating cloth.

[0049] In this embodiment, please refer to Figure 3 , Figure 5 , the first clamping mechanism includes a clamping frame 1611 and a first clamping plate 1613. Symmetrically distributed first clamping plates 1613 are provided in the clamping frame 1611, and a third spring 1612 for driving the two first clamping plates 1613 to approach each other is provided in the clamping frame 1611. A third adjustment groove 1618 is provided on one side of the clamping frame 1611. A third adjustment plate 1615 connected in a sliding manner is provided in the third adjustment groove 1618. The third adjustment plate 1615 is made of a metal material that can be adsorbed by a magnet, and both ends of the third adjustment plate 1615 are fixedly connected with bendable second connectors 1614. The extending ends of the second connectors 1614 respectively pass through the third adjustment groove 1618 and are connected to the corresponding first clamping plates 1613. Symmetrically distributed first limiting grooves 161 for placing the clamping frame 1611 are provided on the winding ring plate 16. One of the first limiting grooves 161 penetrates through the winding ring plate 16. A first recovery groove communicated with the first limiting groove 161 is provided on the fixing plate 11. The clamping frame 1611 is slidably connected in the first recovery groove. A third hydraulic rod 1616 fixedly connected is provided in the first recovery groove. A recovery plate 1617 fixedly connected is provided at the end of the third hydraulic rod 1616. A first electromagnet is provided in the recovery plate 1617. The first electromagnet adsorbs the third adjustment plate 1615 to move so that the recovery plate 1617 is fixedly connected with the clamping frame 1611.

[0050] The designs of the clamping frame 1611 and the first clamping plate 1613 enable the fixation of the clamping frame 1611 through the engagement between the clamping frame 1611 and the first limiting groove 161. The first electromagnet and the third adjusting plate 1615 are designed with magnetically adsorbable materials. When the first clamping mechanism needs to be connected to the winding ring plate 16, only by controlling the third hydraulic rod 1616 to extend can the clamping frame 1611 be driven to extend and inserted into the first limiting groove 161. When it is necessary to separate from the third hydraulic rod 1616, only by canceling the magnetism of the first electromagnet can the clamping frame 1611 be automatically separated from the third hydraulic rod 1616. Meanwhile, under the action of the second connecting piece 1614 and the third spring 1612, after the clamping frame 1611 is separated from the third hydraulic rod 1616, the third adjusting plate 1615 loses the adsorption of the electromagnet and can be controlled to move closer to each other under the action of the third spring 1612, so as to realize that the first clamping plate 1613 can automatically clamp and fix the insulating cloth. At the same time, when separation is required, only by making the first electromagnet regain its magnetism can the magnetism adsorb the third adjusting plate 1615 to move towards the first electromagnet, making the recovery plate 1617 fit and squeeze against the clamping frame 1611 for fixation. At this time, only by controlling the third hydraulic rod 1616 to contract can the automatic separation of the clamping frame 1611 from the winding ring plate 16 be realized. At the same time, when the recovery plate 1617 is fixedly attached to the clamping frame 1611, the third adjusting plate 1615 will automatically move to one end due to magnetism, and thus the first clamping plate 1613 can be driven to move away from each other automatically through the second connecting piece 1614.

[0051] In this embodiment, please refer to Figure 3 , Figure 6 , the second clamping mechanism includes a second clamping plate 145 and a base plate 148. The base plate 148 is detachably connected to the conveying plate 142, and both ends of the base plate 148 are provided with telescopic positioning rods 147. The winding ring plate 16 is provided with symmetrically distributed second limiting grooves 164 for engaging and connecting with the positioning rods 147. One side of the base plate 148 is provided with a plurality of telescopic rods 146, and the ends of the telescopic rods 146 are fixedly connected to the second clamping plate 145. The telescopic movement of the telescopic rods 146 controls the reciprocating movement of the second clamping plate 145, so that the second clamping plate 145 fits close to the base plate 148 to squeeze and fix the insulating cloth.

[0052] Through the engagement between the positioning rod 147 and the second limiting groove 164, the selective connection between the base plate 148 and the winding ring plate 16 is realized, making it detachable. The telescopic movement of the telescopic rod 146 can realize the selective fixation of the insulating cloth by the second clamping plate 145.

[0053] In this embodiment, please refer to Figure 3 , Figure 6 andFigure 7 At both ends of the base plate 148, there are symmetrically distributed positioning grooves 1484. The positioning rod 147 is slidably connected in the positioning groove 1484, and the outer end of the positioning rod 147 is hemispherical. A fourth spring 1486 for driving the positioning rod 147 to automatically pop out is provided in the positioning groove 1484. The elasticity of the fourth spring 1486 makes the hemispherical shape at the end of the positioning rod 147 always located outside the base plate 148. A slidably connected positioning plate 1488 is provided in each of the positioning grooves 1484. The positioning plate 1488 is fixedly connected to the fourth spring 1486, and the other end of the positioning plate 1488 is fixedly connected to an expansion tube 1489. The extending end of the expansion tube 1489 is fixedly connected to the positioning rod 147.

[0054] Due to the design of the fourth spring 1486 and the hemispherical shape at the end of the positioning rod 147, when the base plate 148 moves between the winding ring plates 16, the hemispherical shape can effectively squeeze the positioning rod 147 into the positioning groove 1484 automatically. And the elasticity of the fourth spring 1486 enables the positioning rod 147 to automatically pop out when it moves to the second limiting groove 164, so that the positioning rod 147 is initially engaged and fixedly connected with the second limiting groove 164. With the addition of the expansion and contraction of the expansion tube 1489 and the positioning plate 1488, by further extending the expansion tube 1489, the positioning rod 147 can be completely engaged and fixed with the second limiting groove 164. Such a design is because when the conveying mechanism 14 drives the base plate 148 to move to the first clamping mechanism, it will pass by the second limiting groove 164. If the positioning rod 147 can be directly engaged with the second limiting groove 164 for the first time, it will cause the base plate 148 to be unable to be conveyed to the first clamping mechanism. This mode can not only ensure that the base plate 148 can move to the first clamping mechanism, but also realize the effective fixation of the base plate 148 when it needs to be fixed to the winding ring plate 16.

[0055] In this embodiment, please refer to Figure 3 、 Figure 6 and Figure 7 Inside the base plate 148, there is a linkage groove 1481. A slidably and sealingly connected linkage plate 1482 is provided in the linkage groove 1481. The linkage plate 1482 is made of a material that can be adsorbed by a magnet. A fifth spring 1483 for driving the linkage plate 1482 to automatically return to its initial position is provided in the linkage groove 1481. A second electromagnet for adsorbing the linkage plate 1482 is provided at the bottom of the conveying plate 142. Telescopic diversion hoses 1487 are provided in the positioning grooves 1484. One end of each diversion hose 1487 is communicated with the corresponding expansion tube 1489, and the other end of each diversion hose 1487 is communicated with the corresponding linkage groove 1481.

[0056] The design of the second electromagnet, the diversion hose 1487, and the linkage plate 1482 is such that when the positioning rod 147 needs to be fully engaged with the second limiting groove 164, it only requires the second electromagnet to demagnetize. At this time, under the action of the fifth spring 1483, the linkage plate 1482 returns to its initial position. Through hydraulic transmission, the positioning rod 147 can be fully inserted into the second limiting groove 164. Since the positioning rod 147 will be initially engaged with the second limiting groove 164 preferentially under the action of the fourth spring 1486, after the second electromagnet demagnetizes, the base plate 148 will not drop directly, ensuring the overall stability.

[0057] In this embodiment, please refer to Figure 3 , Figure 6 and Figure 7 , a sixth spring for driving the second clamping plate 145 to automatically separate from the base plate 148 is provided on the telescopic rod 146. A bendable third connecting member 1485 is provided on the second clamping plate 145, and the end of the third connecting member 1485 movably passes through the linkage groove 1481 and is connected to the linkage plate 1482. With such a design, after the base plate 148 is fully engaged and fixed with the second limiting groove 164, the movement of the linkage plate 1482 can drive the second clamping plate 145 to automatically squeeze and fix the end of the insulating cloth through the third connecting member 1485. When the base plate 148 is connected to the conveying plate 142, the sixth spring can automatically open the second clamping plate 145.

[0058] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 , the number of the driving rollers exceeds three, and the driving rollers include a first roller 12 and a second roller 13. The first roller 12 and the second roller 13 are annularly distributed. A first shaft rotatably connected is provided at the bottom of the first roller 12, and the first shaft is arranged on the processing base 1. A driving motor for driving one of the first rollers 12 to rotate forward and backward is provided on the processing base 1. A hidden groove 131 is provided on the processing base 1. A second shaft 132 rotatably connected is provided at the bottom of the second roller 13, and the bottom of the second shaft 132 is rotatably connected to the hidden groove 131. A fourth hydraulic rod 133 for driving the second shaft 132 to rotate vertically is provided in the hidden groove 131. Buffer rubbers are provided on the surfaces of the first roller 12 and the second roller 13.

[0059] In this embodiment, the first limiting groove 161 and the second limiting groove 164 are on the same straight line.

[0060] In this embodiment, a cutting knife that can move back and forth is provided on the pressing plate 144, and a hydraulic rod is also provided on the pressing plate 144, and the hydraulic rod drives the cutting knife to reciprocate.

[0061] When this application is in use:

[0062] First, place the current transformer ring on the base plate 148. Control the fourth hydraulic rod 133 to drive the second roller 13 to rotate to the vertical state, so that the second roller 13 and the first roller 12 squeeze and limit the current transformer ring. At the same time, control the second hydraulic rod 143 to squeeze and fix the end of the insulating cloth, and control the first hydraulic rod 141 to extend, driving the base plate 148 to move towards the first clamping mechanism;

[0063] When the base plate 148 moves to the first clamping mechanism, control the third hydraulic rod 1616 to drive the clamping frame 1611 to insert into the first limiting groove 161. At this time, the two first clamping plates 1613 are in a separated state. When the base plate 148 moves to the first clamping mechanism, the end insulating cloth is located within the first clamping plate 1613. At this time, only need to control the first electromagnet to release magnetism, and the third adjusting plate 1615 can return to its initial position under the action of the third spring 1612. At the same time, the third spring 1612 drives the first clamping plates 1613 to approach each other, so that the first clamping plates 1613 automatically fix the end of the insulating cloth;

[0064] Then control the second hydraulic rod 143 to release the fixing of the insulating cloth by the pressing plate 144, control the first hydraulic rod 141 to contract, and at the same time control the winding motor to drive the winding ring plate 16 to rotate, so that the insulating cloth is evenly wound around the outer side of the support rod 163. When the insulating cloth is wound to the set length, stop the rotation of the winding motor, make the positioning rod 147 located above the second limiting groove 164, then control the base plate 148 to move downward, so that the positioning rod 147 is initially engaged with the second limiting groove 164. Then release the magnetism of the second electromagnet, and the linkage plate 1482 automatically returns to its initial position under the action of the fifth spring 1483. Through the transmission of hydraulic pressure, the positioning rod 147 is completely engaged and fixed with the second limiting groove 164, and the linkage plate 1482 will also drive the second clamping plate 145 to automatically squeeze and fix the insulating cloth through the third connecting piece 1485. Then control the cutting knife to cut off the insulating cloth. After the outermost end of the insulating cloth is fixed in this way, when there is only the last part of the insulating cloth left, it can be wound around the outer side of the current transformer ring better and more tightly. Control the clamping force of the second clamping plate 145 on the insulating cloth, so that the insulating cloth can finally automatically separate from the second clamping plate 145;

[0065] At the same time, make the first electromagnet restore magnetism, and control the third hydraulic rod 1616 to make the recovery plate 1617 fit with the clamping frame 1611. Through the adsorption of the third adjusting plate 1615 and the first electromagnet, the recovery plate 1617 is connected and fixed with the clamping frame 1611. At the same time, the displacement of the third adjusting plate 1615 can drive the automatic separation of the first clamping plates through the transmission of the second connecting piece 1614. Then only need to control the third hydraulic rod 1616 to contract, and the clamping frame 1611 can be separated from the winding ring plate 16;

[0066] Next, connect and fix the insulating cloth inside the inner ring of the winding ring plate 16 to the transformer ring. At this time, the driving motor and the winding motor can be started to drive the insulating cloth to automatically wind around the transformer ring;

[0067] After winding is completed, control the first hydraulic rod 141 to move the conveying plate 142 to the base plate 148, and turn on the second electromagnet to connect the base plate 148 and the conveying plate 142. At this time, the linkage plate 1482 moves, drives the second clamping plate 145 to automatically open through the third connecting piece 1485, and the telescopic tube 1489 contracts, driving the positioning rod 147 to contract to the initial position. Then, control the first hydraulic rod 141 to move upward to make the insulating cloth enter between the second clamping plates 145 and wait for the next conveyance.

[0068] A processing method of a processing device for producing a metering transformer, using the processing device for producing a metering transformer, which is characterized by including the following steps:

[0069] S1 First, place the annular transformer ring on the processing base 1, and control the driving roller to wrap the transformer ring. At this time, the center of the transformer ring is located in the notch groove;

[0070] S2 At the same time, connect and fix the first clamping mechanism to the winding ring plate 16. Then, control the conveying mechanism 14 to convey the end of the insulating cloth to the first clamping mechanism, so that the first clamping mechanism fixes the end of the insulating cloth. Then, release the fixing of the insulating cloth by the conveying mechanism 14 to make the conveying mechanism 14 return to the initial position. At the same time, control the winding ring plate 16 to rotate. At this time, the insulating cloth will automatically wind around the outside of the support rod 163 in a ring shape;

[0071] S3 When the winding of the insulating cloth is completed, control the second clamping mechanism to connect and fix to the winding ring plate 16, and make the second clamping mechanism clamp and fix the other end of the insulating cloth;

[0072] Next, S4 separates the first clamping mechanism. Before the insulating cloth is wound, the end of the insulating cloth is connected and fixed to the transformer ring. At this time, the winding ring plate 16 and the driving roller can be controlled to rotate, and the rotation speeds of the two are controlled so that the insulating cloth is evenly wound on the outer side of the transformer ring. During the rotation of the winding ring plate 16, the insulating cloth will sequentially press the corresponding support rods 163. When the support rod 163 is pressed from one end to the other end by the insulating cloth, the support rod 163 contracts into the slider 1631. At this time, another support rod 163 can be automatically switched to support the insulating cloth, and the slider 1631 in which the support rod 163 contracts automatically moves back to restore the initial position, and the support rod 163 extends again to wait for the next support. Through the sequential switching mode of the support rods 163, the insulating cloth can always be kept in a tensioned state during the winding process, so that the insulating cloth can be more closely attached and wound on the outer side of the transformer ring;

[0073] S5 After the insulating cloth winding is completed, control the second clamping mechanism to release the fixation of the insulating cloth, and at the same time release the fixation of the driving roller on the transformer ring. At this time, the transformer ring with the insulating cloth wound can be sent to the next production step.
