Description

Technical Field

[0001] The invention belongs to the technical field of production and processing of metering transformers, and in particular relates to processing equipment and a processing method for producing metering transformers. Background Art

[0002] A metering transformer is a transformer used for the purpose of measuring and accurately measuring voltage, current, electric energy, etc. in a circuit. It is a general term for measuring voltage transformers and measuring current transformers.

[0003] The inventors found that during the production and processing of existing metering transformers, it is necessary to wrap a circle of insulating cloth around the outside of the circular ring inside the transformer. In the existing technology, equipment similar to a winding machine is used for winding. However, since the diameter of the circular ring in some transformers is too small, the winding ring plate in the winding machine is too large and cannot pass directly through the circular ring. Therefore, for such small circular rings, manual wrapping and winding are used, which makes the overall production and processing efficiency low.

[0015] A processing method for a processing device for producing a metering transformer, using the processing device for producing a metering transformer, is characterized in that it comprises the following steps: S1 first places the annular transformer ring on the processing base, and controls the driving roller to wrap the transformer ring. At this time, the center of the transformer ring is located in the notch groove; S2 simultaneously connects and fixes the first clamping mechanism and the winding ring plate, then 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 releases the fixing of the insulating cloth by the conveying mechanism, restores the conveying mechanism to the initial position, and controls the winding ring plate to rotate, at which time the insulating cloth will automatically be wound in a ring shape to the outside of the support rod; S3: After the insulating cloth is wound, the second clamping mechanism is controlled to be connected and fixed to the winding ring plate, and the second clamping mechanism is used to clamp and fix the other end of the insulating cloth; S4 then separates the first clamping mechanism, and 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 and the driving roller can be controlled to rotate, and the rotation speed of the two can be controlled to make the insulating cloth evenly wound around the outside of the transformer ring. During the rotation of the winding ring plate, the insulating cloth will squeeze the corresponding support rods in turn.

At this time, another support rod can be automatically switched to support the insulating cloth, and the slider of the retracted support rod automatically moves back to restore the initial position, and the support rod is extended again to wait for the next support. Through the mode of sequential switching of the support rods, the insulating cloth can always be kept in a tensioned state during the winding process, so that the insulating cloth can be more closely wrapped around the outside of the transformer ring. S5 When the insulating cloth is wound, the second clamping mechanism is controlled to release the fixing of the insulating cloth, and the driving roller is released from the fixing of the transformer ring.

[0016] Compared with the prior art, the present invention has the following technical effects: The design of the winding ring plate, the support rod and the slider can make the support rod reciprocate through the reciprocating motion of the slider, and then cooperate with the extension and contraction of the support rod so that the insulating cloth can squeeze the support rod and the slider to move toward one end during the winding process. When the support rod moves to the end, the support rod is contracted to make the insulating cloth automatically switch to another support rod for support, and the slider will automatically return to the initial position after the support rod is contracted. At the same time, the support rod can also be extended again to wait for the next support. Through the sequential switching mode of the support rod, the insulating cloth can always be kept in a tensioned state during the winding process, so that the insulating cloth can be better and more tightly wound on the transformer ring; Moreover, this design integrates the insulating cloth into the winding ring plate, so that when winding some transformer rings with smaller diameters, it can pass through better and wind the transformer rings better; mechanized winding is achieved, and production efficiency is improved.

[0017] The addition of the conveying mechanism, the first clamping mechanism and the second clamping mechanism makes the whole more intelligent, reduces manual operations and improves efficiency.

[0033] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 A processing device for producing a metering transformer, used for winding the insulating cloth on the transformer ring, comprising a processing base 1, on which two symmetrically distributed and synchronously rotatable winding ring plates 16 are provided, and the two winding ring plates 16 are provided with a notch groove for inserting the transformer ring at the same place, and the processing base 1 is provided with a plurality of rotatable driving rollers for driving the transformer ring to rotate, and the inner side wall of the winding ring plate 16 is provided with a plurality of evenly distributed arc grooves 162, and the plurality of arc grooves 162 form a circle, and the arc grooves 16 2 are provided with matching sliders 1631 that can move back and forth, and retractable support rods 163 are provided on the outer sides of the sliders 1631. A detachable first clamping mechanism for clamping and fixing the insulating cloth is provided between the winding ring plates 16 located at the inner ring, and a rotatable and wound insulating cloth is provided above the winding ring plates 16, and a conveying mechanism 14 for conveying the insulating cloth to the first clamping mechanism is provided above the winding ring plates 16. A detachable second clamping mechanism for fixing the ends of the insulating cloth is also provided between the winding ring plates 16 located at the outer ring.

[0034] The design of the winding ring plate 16, the support rod 163 and the slider 1631 can make the support rod 163 reciprocate through the reciprocating motion of the slider 1631, and cooperate with the extension and contraction of the support rod 163, so that the insulating cloth can squeeze the support rod 163 and the slider 1631 to move toward one end during the winding process, and when the support rod 163 moves to the end, the support rod 163 is contracted, so that the insulating cloth automatically switches to another support rod 163 for support, and the slider 1631 after the support rod 163 is contracted will automatically return to the initial position, and the support rod 163 can also be extended again to wait for the next support, and the insulating cloth can be kept in a tensioned state during the winding process through the sequential switching mode of the support rod 163, so that the insulating cloth can be better and tighter wound on the transformer ring; Moreover, such a design integrates the insulating cloth into the winding ring plate 16, so that when winding some transformer rings with smaller diameters, the insulating cloth can pass through better and the transformer rings can be wound better; The addition of the conveying mechanism 14, the first clamping mechanism and the second clamping mechanism makes the whole more intelligent, reduces manual operations and improves efficiency.

[0035] In this example, see Figure 2 , Figure 4The arc groove 162 has a convex cross-section, and a first spring 1637 is provided in the arc groove 162 for driving the slider 1631 to return to its initial position. A first adjustment groove 1632 is provided on the outer wall of the slider 1631, and the support rod 163 is slidably connected in the first adjustment groove 1632. A second spring 1633 is provided in the first adjustment groove 1632 for driving the support rod 163 to automatically pop out. The slider 1631 located in the arc groove 162 is provided with a through-type second adjustment groove 1638, and the second adjustment groove 1638 is provided with a push rod 1634 with a sliding connection, and the end of the push rod 1634 is connected to a first connecting piece 1635 that is bendable, and the extended end of the first connecting piece 1635 movably passes through the first adjustment groove 1632 and is connected and fixed to the support rod 163. After the slider 1631 moves to one side, the push rod 1634 contacts and squeezes the side wall of the arc groove 162, and the support rod 163 is automatically recovered into the first adjustment groove 1632 through the transmission of the first connecting piece 1635.

[0036] The design of the first spring 1637 enables the insulating cloth to squeeze the first spring 1637 during the winding process, so that the first spring 1637 stores energy. The addition of the push rod 1634 and the first connecting member 1635 enables the push rod 1634 to move in the second adjusting groove 1638 through the squeezing between the push rod 1634 and the inner wall of the arc groove 162 when the slider 1631 moves to the end, thereby realizing the automatic contraction of the support rod 163 through the first connecting member 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 energy stored in the first spring 1637 when the insulating cloth switches to the next support rod 163, because there is no squeezing 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 motion of the slider 1631 and the support rod 163, as well as the telescopic control of the support rod 163.

[0037] In this example, see Figure 1 , Figure 2 and Figure 3 The processing base 1 is provided with a winding groove 112, and two fixedly connected fixing plates 11 are provided at the upper end of the winding groove 112. The winding ring plates 16 are rotatably connected with the corresponding fixing plates 11, and the fixing plates 11 and the winding groove 112 are provided with a plurality of rotatable winding rollers 111 used to drive the two winding ring plates 16 to rotate synchronously. The fixing plate 11 is provided with a winding motor used to drive the winding rollers 111 to rotate. The winding motor and the winding rollers 111 can realize the synchronous rotation of the two winding ring plates 16, and the fixing plate 11 is provided with a winding ring groove for limiting the rotation of the winding ring plate 16.

[0038] In this example, see Figure 3 and Figure 6 The fixed plate 11 is provided with a placement shaft 15, and the insulating cloth is placed on the placement shaft 15 in a winding shape. The fixed plate 11 is provided with a fixedly connected first hydraulic rod 141, and the end of the first hydraulic rod 141 is connected to the conveying mechanism 14, and the conveying mechanism 14 includes a conveying plate 142 and an extrusion plate 144. The first hydraulic rod 141 is fixedly connected to the conveying plate 142, and the conveying plate 142 is provided with a plurality of fixedly connected second hydraulic rods 143, and the end of the second hydraulic rod 143 is connected and fixed to the extrusion 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 extrusion and fixation of the end of the insulating cloth, so that the conveying mechanism 14 can realize the fixation and conveyance of the insulating cloth.

[0039] In this example, see Figure 3 , Figure 5 The first clamping mechanism includes a clamping frame 1611 and a first clamping plate 1613, wherein the clamping frame 1611 is provided with symmetrically distributed first clamping plates 1613, and the clamping frame 1611 is provided with a third spring 1612 for driving the two first clamping plates 1613 to approach each other, a third adjusting groove 1618 is provided on one side of the clamping frame 1611, and a third adjusting plate 1615 slidably connected is provided in the third adjusting groove 1618, and the third adjusting plate 1615 is made of a metal material that can be adsorbed by a magnet, and fixedly connected and bendable second connecting members 1614 are provided at both ends of the third adjusting plate 1615, and the extending ends of the second connecting member 1614 are movable through the third adjusting groove 1618 and The corresponding first clamping plate 1613 is connected, and the winding ring plate 16 is provided with a first limiting groove 161 which is symmetrically distributed and used for placing the clamping frame 1611, one of the first limiting grooves 161 passes through the winding ring plate 16, and the fixed plate 11 is provided with a first recovery groove which is connected with the first limiting groove 161, and the clamping frame 1611 is slidably connected in the first recovery groove, and a fixedly connected third hydraulic rod 1616 is provided in the first recovery groove, and a fixedly connected recovery plate 1617 is provided at the end of the third hydraulic rod 1616, and a first electromagnet is provided in the recovery plate 1617, and the first electromagnet adsorbs the third adjustment plate 1615 to move so that the recovery plate 1617 is connected and fixed to the clamping frame 1611.

[0040] The design of the clamping frame 1611 and the first clamping plate 1613 can realize the fixation of the clamping frame 1611 through the engagement between the clamping frame 1611 and the first limiting groove 161, and the first electromagnet and the third adjusting plate 1615 are designed as materials that can be adsorbed by magnets, so that when the first clamping mechanism needs to be connected with the winding ring plate 16, it is only necessary to control the extension of the third hydraulic rod 1616 to drive the clamping frame 1611 to extend and insert into the first limiting groove 161, and when it is necessary to separate from the third hydraulic rod 1616, it is only necessary to cancel the magnetism of the first electromagnet to automatically separate the clamping frame 1611 from the third hydraulic rod 1616. At the same time, under the action of the second connecting member 1614 and the third spring 1612, when the clamping frame 1611 is separated from the third hydraulic rod 1616, the third adjusting plate 16 15 loses the adsorption of the electromagnet, and under the action of the third spring 1612, the first clamping plates 1613 can be controlled to move closer to each other, so that the first clamping plates 1613 can automatically clamp and fix the insulating cloth. At the same time, when separation is required, it is only necessary to restore the magnetism of the first electromagnet, and the magnetism can adsorb the third adjustment plate 1615 to move toward the first electromagnet, so that the recovery plate 1617 and the clamping frame 1611 are pressed and fixed. At this time, it is only necessary to control the third hydraulic rod 1616 to contract, so that the clamping frame 1611 and the winding ring plate 16 can be automatically separated. At the same time, when the recovery plate 1617 and the clamping frame 1611 are pressed and fixed, the third adjustment plate 1615 will automatically move to one end due to magnetism, thereby driving the first clamping plates 1613 to automatically move away from each other through the second connecting member 1614.

[0041] In this example, see 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 retractable positioning rods 147 are provided at both ends of the base plate 148. The winding ring plate 16 is provided with a second limiting groove 164 which is symmetrically distributed and used for the positioning rod 147 to be engaged and connected. A plurality of telescopic rods 146 are provided on one side of the base plate 148. The ends of the telescopic rods 146 are connected and fixed 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 and the base plate 148 are close to each other to squeeze and fix the insulating cloth.

[0042] By engaging the positioning rod 147 with the second limiting groove 164, a selective connection between the base plate 148 and the winding ring plate 16 is achieved, making it detachable. The extension and retraction of the telescopic rod 146 can achieve the selective fixation of the insulating cloth by the second clamping plate 145.

[0043] In this example, see Figure 3 , Figure 6 and Figure 7 The base plate 148 has symmetrically distributed positioning grooves 1484 at both ends, the positioning rod 147 is slidably connected in the positioning groove 1484, and the outer end of the positioning rod 147 is hemispherical, and the positioning groove 1484 is provided with a fourth spring 1486 for driving the positioning rod 147 to automatically pop out. The elasticity of the fourth spring 1486 ensures that the hemispherical shape of the end of the positioning rod 147 is always located on the outside of the base plate 148, and the positioning groove 1484 is provided with a slidably connected positioning plate 1488, the positioning plate 1488 is fixedly connected to the fourth spring 1486, and the other end of the positioning plate 1488 is provided with a fixedly connected telescopic tube 1489, and the extending end of the telescopic tube 1489 is fixedly connected to the positioning rod 147.

[0044] The hemispherical design of the fourth spring 1486 and the end of the positioning rod 147, the hemispherical design of the end of the positioning rod 147, can make the hemispherical shape effectively squeeze the positioning rod 147 into the positioning groove 1484 automatically when the base plate 148 moves to between the winding ring plate 16, and the elasticity of the fourth spring 1486 can make the positioning rod 147 automatically pop out when it moves to the second limiting groove 164, so that the positioning rod 147 is initially engaged and connected with the second limiting groove 164, and the extension and contraction of the telescopic tube 1489 and the addition of the positioning plate 1488 can be achieved through the telescopic tube The further extension of 1489 can realize that the positioning rod 147 is completely engaged and fixed with the second limit groove 164. This design is because when the conveying mechanism 14 drives the base plate 148 to move to the first clamping mechanism, it will pass through the second limit groove 164. If the positioning rod 147 can directly engage with the second limit groove 164 for the first time, it will make it impossible to convey 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 that the base plate 148 can be effectively fixed when it needs to be fixed to the winding ring plate 16.

[0045] In this example, see Figure 3 , Figure 6 and Figure 7 A linkage groove 1481 is provided in the base plate 148, a linkage plate 1482 that is slidably and sealed 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 is provided in the linkage groove 1481 for driving the linkage plate 1482 to automatically restore the initial position, a second electromagnet is provided at the bottom of the conveying plate 142 for adsorbing the linkage plate 1482, a retractable guide hose 1487 is provided in the positioning groove 1484, one end of the guide hose 1487 is connected to the corresponding telescopic tube 1489, and the other end of the guide hose 1487 is connected to the corresponding linkage groove 1481.

[0046] The design of the second electromagnet, the guide hose 1487 and the linkage plate 1482 is that when the positioning rod 147 needs to be fully engaged with the second limit groove 164, only the second electromagnet needs to be demagnetized. At this time, the linkage plate 1482 is restored to its initial position under the action of the fifth spring 1483, and the positioning rod 147 can be fully inserted into the second limit groove 164 through hydraulic transmission. Because the positioning rod 147 will preferentially engage with the second limit groove 164 under the action of the fourth spring 1486, the base plate 148 will not fall directly after the second electromagnet is demagnetized, thereby ensuring the overall stability.

[0047] In this example, see Figure 3 , Figure 6 and Figure 7 The telescopic rod 146 is provided with a sixth spring for driving the second clamping plate 145 to automatically separate from the base plate 148. The second clamping plate 145 is provided with a bendable third connecting member 1485. The end of the third connecting member 1485 movably passes through the linkage groove 1481 and is connected to the linkage plate 1482. Such a design enables the base plate 148 to be completely 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.

[0048] In this example, see Figure 1 , Figure 2 and Figure 3 The number of the driving rollers is more than 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 distributed in a ring shape, a first shaft for rotation connection is provided at the bottom of the first roller 12, the first shaft is arranged on a processing base 1, a driving motor for driving one of the first rollers 12 to rotate forward and reverse is provided on the processing base 1, a hidden groove 131 is provided on the processing base 1, a second shaft 132 for rotation connection is provided at the bottom of the second roller 13, the bottom of the second shaft 132 is rotationally 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, and buffer rubber is provided on the surfaces of the first roller 12 and the second roller 13.

[0049] In this embodiment, the first limiting groove 161 and the second limiting groove 164 are on the same straight line.

[0050] In this embodiment, a cutting knife that can move back and forth is provided on the extrusion plate 144 , and a hydraulic rod is also provided on the extrusion plate 144 , and the hydraulic rod drives the cutting knife to reciprocate.

[0051] When using this application: First, place the transformer ring on the base plate 148, control the fourth hydraulic rod 133 to drive the second roller 13 to rotate to a vertical state, so that the second roller 13 and the first roller 12 squeeze and limit the 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 toward the first clamping mechanism; When the base plate 148 moves to the first clamping mechanism, the third hydraulic rod 1616 is controlled to drive the clamping frame 1611 to insert into the first limiting groove 161. At this time, the two first clamping plates 1613 are separated. When the base plate 148 moves to the first clamping mechanism, the insulating cloth at the end is located in the first clamping plate 1613. At this time, it is only necessary to control the first electromagnet to demagnetize, and the third adjustment plate 1615 can restore the 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 ends of the insulating cloth. Then, the second hydraulic rod 143 is controlled to release the fixing of the extrusion plate 144 on the insulating cloth, and the first hydraulic rod 141 is controlled to contract, and at the same time, the winding motor is controlled to drive the winding ring plate 16 to rotate, so that the insulating cloth is evenly wound around the outside of the support rod 163. When the insulating cloth is wound to a set length, the winding motor is stopped to make the positioning rod 147 located above the second limiting groove 164, and then the base plate 148 is controlled to move downward, so that the positioning rod 147 is initially engaged with the second limiting groove 164, and then the magnetism of the second electromagnet is released, and the linkage plate 1482 is moved under the action of the fifth spring 1483. Automatically restore the initial position, through hydraulic transmission, the positioning rod 147 is completely engaged and fixed with the second limiting groove 164, and the linkage plate 1482 will also synchronously drive the second clamping plate 145 through the third connecting member 1485 to automatically squeeze and fix the insulating cloth, and then control the cutting knife to cut the insulating cloth, so that after the outermost end of the insulating cloth is fixed, when only the last part of the insulating cloth is left, it can be better and more tightly wound on the outside of the transformer ring; control the clamping force of the second clamping plate 145 on the insulating cloth, so that the insulating cloth can finally be automatically separated from the second clamping plate 145; At the same time, the first electromagnet is restored to magnetism, and the third hydraulic rod 1616 is controlled to make the recovery plate 1617 fit with the clamping frame 1611. The recovery plate 1617 is connected and fixed to the clamping frame 1611 by the adsorption of the third adjustment plate 1615 and the first electromagnet. At the same time, the displacement of the third adjustment plate 1615 can be driven by the second connecting member 1614 to automatically separate the first clamping plate. Then, the third hydraulic rod 1616 only needs to be controlled to contract to separate the clamping frame 1611 from the winding ring plate 16. Then, the insulating cloth of the inner ring of the winding ring plate 16 is connected and fixed 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. After the winding is completed, the first hydraulic rod 141 is controlled to move the conveying plate 142 to the base plate 148, and the second electromagnet is turned on to connect the base plate 148 and the conveying plate 142. At this time, the linkage plate 1482 moves, and the second clamping plate 145 is automatically opened through the third connecting piece 1485, and the telescopic tube 1489 contracts, driving the positioning rod 147 to contract to the initial position. Then the first hydraulic rod 141 can be controlled to move upward, so that the insulating cloth enters between the second clamping plates 145 and waits for the next conveying.

[0052] A processing method for a processing device for producing a metering transformer, using the processing device for producing a metering transformer, is characterized in that it comprises the following steps: S1 first places the annular transformer ring on the processing base 1, and controls the driving roller to wrap the transformer ring. At this time, the center of the transformer ring is located in the notch groove; S2 simultaneously connects and fixes the first clamping mechanism and the winding ring plate 16, then controls 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 releases the fixing of the insulating cloth by the conveying mechanism 14, so that the conveying mechanism 14 returns to the initial position, and controls the winding ring plate 16 to rotate, at which time the insulating cloth will automatically be wound in a ring shape to the outside of the support rod 163; S3: After the insulating cloth is wound, the second clamping mechanism is controlled to be connected and fixed to the winding ring plate 16, and the second clamping mechanism is used to clamp and fix the other end of the insulating cloth; S4 then separates the first clamping mechanism, and 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 speed of the two can be controlled to make the insulating cloth evenly wound around the outside of the transformer ring. During the rotation of the winding ring plate 16, the insulating cloth will squeeze the corresponding support rods 163 in sequence. When the support rod 163 is squeezed from one end to the other end by the insulating cloth, the support rod 163 is retracted into the slider 1631. At this time, another support rod 163 can be automatically switched to support the insulating cloth, and the slider 1631 of the retracted support rod 163 automatically moves back to restore the initial position, and the support rod 163 is extended again to wait for the next support. Through the mode of sequential switching 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 more closely wrapped around the outside of the transformer ring. S5 When the insulating cloth is wound, the second clamping mechanism is controlled to release the fixing of the insulating cloth, and the driving roller is released from the fixing of the transformer ring. At this time, the transformer ring wound with the insulating cloth can be sent to the next production step.
