Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, and specifically relates to a fast winding machine for current transformers. Background Technology

[0002] In the production of power equipment such as voltage transformers and current transformers, transformer winding machines are key pieces of equipment. The manufacturing of transformers requires winding a large number of turns of coil with high precision. Transformer winding machines can meet the demands of high-quality production, ensuring the stable performance and accuracy of the transformers.

[0003] Currently, the clamping structure design of high-speed instrument transformer winding machines on the market varies significantly depending on the shape of the instrument transformer during the winding process. Specifically, when the instrument transformer is circular, the industry commonly uses a three-wheel structure to achieve stable rotation and clamping of the transformer. This design ensures the accuracy and stability of the circular instrument transformer during the winding process. However, when the instrument transformer is transformed into a frame-shaped structure, the original wheel structure is no longer suitable. In this case, a robotic arm clamping method is required to adapt to the special shape of the frame-shaped instrument transformer. Although these different clamping structures can meet the clamping and winding requirements of circular and frame-shaped instrument transformers respectively, they cannot be universally applied to a single machine. This means that users cannot process both circular and frame-shaped instrument transformers simultaneously on the same high-speed instrument transformer winding machine. This undoubtedly increases the limitations of the equipment's use, restricts its application range, and increases the user's equipment investment costs and operational complexity. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed winding machine for current transformers, so as to solve the problem mentioned in the background art that current winding machines cannot perform universal winding processing for annular current transformers and frame-type current transformers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid winding machine for current transformers, comprising a base plate; a winding assembly is provided on the top of the base plate; a clamping mechanism is provided on one side of the winding assembly for clamping the current transformer and then rotating the current transformer to wind copper wire onto the current transformer component, thereby producing a finished current transformer; the clamping mechanism includes:

[0006] A ring-shaped transmission assembly; the ring-shaped transmission assembly includes at least one driving member located outside the winding assembly, and two driven members symmetrically arranged on both sides of the winding assembly; the ring-shaped transmission assembly is distributed in a three-point configuration;

[0007] A flexible transmission component is disposed below the annular transmission component; the flexible transmission component consists of a lifting plate and a flexible transmission section placed above the lifting plate; the flexible transmission section is connected to the drive section after horizontal sliding.

[0008] A fixed plate is disposed below the lifting plate, and a support plate passes through the edge of the fixed plate and the two are fixedly connected; the bottom end of the support plate is fixed to the base plate; the edge of the lifting plate is provided with a slot for the support plate to slide through.

[0009] A lifting assembly is installed between the fixed plate and the lifting plate; the lifting assembly moves up and down by the horizontal sliding of the drive unit.

[0010] In a preferred embodiment of this invention, the driving component of the annular transmission assembly includes a servo motor and a driving wheel mounted on the output end of the servo motor; the driven component includes a support rod and a driven wheel rotatably mounted on the top of the support rod. During the winding process of the annular current transformer, the winding assembly is first opened, and then the current transformer is placed between the driving wheel and the driven wheel, ensuring that the current transformer does not fall off. Subsequently, the servo motor and the winding assembly start synchronously. The winding assembly winds copper wire onto the current transformer, while the driving wheel is driven by the servo motor to rotate the current transformer, thereby winding copper wire around the annular current transformer. When installing the circular current transformer, the servo motor needs to be moved slightly away from the winding assembly to facilitate the placement of the annular current transformer between the driving wheel and the driven wheel. After placement, the servo motor is pushed back into its original position. The system achieves limiting and clamping of the annular current transformer, and in the subsequent rotation of the drive wheel, it drives the annular current transformer to rotate, while the driven wheel rotates under the rotation of the annular current transformer, and the driven wheel can also clamp the annular current transformer; the top of the base plate is equipped with two parallel slide rails, and the top of the slide rails has a strip groove. The servo motor is equipped with a mounting sleeve, and the two ends of the mounting sleeve are bent and overlapped on the slide rails. The bent parts of the mounting sleeve have screw holes. In adjusting the position of the servo motor, the servo motor with the mounting sleeve fixed is first pulled or pushed to the designated position, and then the bolt is passed through the screw hole and pressed against the strip groove at the top of the slide rail, thereby achieving clamping and fixing the position of the servo motor. The bottom of the support rod is installed in the strip groove of the slide rail; the bearing plate and the slide rail do not contact each other.

[0011] In a preferred embodiment of the present invention, the flexible transmission unit includes a transmission belt; a through groove is provided in the middle of the lifting plate; two limiting wheels are provided at the end of the lifting plate away from the winding assembly; a sleeve is also fitted on the support rod, which is located directly below the driven wheel, wherein the outer diameter of the sleeve is equal to that of the driven wheel. Because their outer diameters are equal, the sleeve can be smoothly moved into the driven wheel during subsequent lifting of the transmission belt, and can also be smoothly moved onto the sleeve during subsequent descent; the transmission belt is fitted around the limiting wheels and the sleeve to achieve the installation of the transmission belt; the surface of the lifting plate has openings along the inner and outer walls of the transmission belt. The device is equipped with multiple auxiliary limiting holes, and a main limiting hole is provided at one end of the lifting plate near the winding assembly. An integral support plate is also fixed at one end of the transmission belt near the winding assembly. Part of the transmission belt overlaps the support plate. An inner bearing is also sleeved on the support rod, and the inner bearing is located between the sleeves. The inner bearing not only connects the support rod and the sleeve, but also prevents the sleeve from rotating when the support rod rotates, ensuring that the transmission belt is stationary when not in use. The support plate is sleeved on the outside of the sleeve. During the subsequent lifting of the lifting plate, the support plate will be sleeved on the outside of the driven wheel. To avoid transmission obstruction, the support plate and the sleeve do not contact each other.

[0012] As a preferred technical solution of the present invention, a second through slot is provided in the middle of the fixed plate. The vertical projection areas of the second through slot and the first through slot completely overlap. The output end of the servo motor passes through the second through slot and the first through slot, thereby ensuring that the servo motor is not blocked by the lifting plate and the fixed plate when moving horizontally. Multiple auxiliary limiting rods passing through the auxiliary limiting holes and a main limiting rod passing through the main limiting hole are fixed on the top of the fixed plate. The main limiting rod contacts the outer surface of the transmission belt. By setting the auxiliary limiting rod and the main limiting rod, the transmission belt can be limited and stored when not in use, avoiding the phenomenon of the transmission belt becoming scattered.

[0013] In a preferred embodiment of the present invention, the lifting assembly comprises two sets, symmetrically distributed around the center of the second through slot. Each set of lifting assemblies includes a push plate horizontally placed on top of a fixed plate. A connecting rod is rotatably connected to one end of the push plate, and a lifting rod is rotatably connected to the top of the connecting rod. The top of the lifting rod is fitted against the bottom of the lifting plate, facilitating subsequent lifting of the lifting plate via the lifting rod. A mounting seat is also fixedly provided on the top of the fixed plate, and the mounting seat is rotatably connected to the other end of the lifting rod. A middle plate is also fixedly provided on the inner side of the push plate, and the middle plate is sleeved on the output shaft of the servo motor. A bearing is also provided between the middle plate and the output shaft of the servo motor. The bearing enables the servo motor to slide horizontally, driving the middle plate to move. At the same time, it ensures that the output shaft of the servo motor will not make direct contact with the middle plate during rotation. When the servo motor slides horizontally, the output end of the servo motor will drive the middle plate to move. The middle plate will synchronously drive the push plate to move. The push plate will pull the bottom of the connecting rod horizontally, causing the connecting rod to rotate. Since the top of the lifting rod is rotatably connected to the connecting rod, the lifting rod rotates itself under the horizontal movement of the connecting rod, gradually changing from an inclined state to a vertical state. During this rotation and lifting process, the bottom of the lifting rod rotates around the mounting base, while the top of the lifting rod is lifted, thereby lifting the bottom of the lifting plate and thus raising the height of the lifting plate.

[0014] As a preferred technical solution of the present invention, the top of the lifting plate is provided with two sets of tensioning components. The two sets of tensioning components are symmetrically distributed around the center of the through slot. Each set of tensioning components includes a fixed block fixed to the top of the lifting plate and a movable block rotatably connected to the fixed block. A torsion spring is also installed between the movable block and the fixed block. A tensioning wheel is installed at the end of the movable block away from the fixed block. When the frame-type current transformer is wound by the transmission belt, the tensioning components will be used. In use, under the action of the rebound force of the torsion spring, the fixed block and the movable block will expand outward, so that the tensioning wheel abuts against the inner wall of the transmission belt. The tensioning wheel abuts against the inner wall of the transmission belt. When the frame-type current transformer is transmitted by the transmission belt, since the frame structure has a long side and a short side, in order to ensure the stable positioning and transmission of the frame-type current transformer by the transmission belt, it is necessary to ensure that the transmission belt always has a tension force. Therefore, the tensioning components can tighten the transmission belt towards the outside of the lifting plate, thereby achieving the adjustment of the tension of the transmission belt.

[0015] As a preferred technical solution of the present invention, the top surface of the lifting plate is further provided with two limiting grooves, each limiting groove being respectively disposed inside each tensioning assembly. A locking assembly is also disposed within the limiting groove, the locking assembly including a locking plate having a horizontal portion and an inclined portion. A shaft passes through the intersection of the horizontal portion and the inclined portion of the locking plate. The shaft is not shown in the figure, but the hole at the intersection for the shaft to pass through is shown. The locking plate rotates around the shaft, and the horizontal portion of the locking plate rotates from a horizontal position towards... The downward rotation of the limiting groove, and the upward rotation from the bottom of the limiting groove to a horizontal position, prevents the horizontal part of the locking plate from excessively tilting due to being pressed against by the clamping post later. It also ensures that the clamping post remains in contact with the horizontal part of the locking plate during the initial horizontal sliding phase. A locking post is fixed at one end of the top surface of the horizontal part of the locking plate, with its top protruding from the limiting groove and abutting against the inner side of the movable block. When the drive belt is not in use, to ensure that the drive belt can rise synchronously with the lifting plate, the entire drive belt can be limited by the main limiting rod and the auxiliary limiting rod, but not... It should have tension to prevent the drive belt from being too tight on the sleeve and unable to separate. Therefore, the locking pin can limit the movable block and tension wheel, preventing the tension wheel from contacting the inner wall of the drive belt. The locking assembly also includes a connecting block fixed to the end of the push plate. A pressing pin is installed on the connecting block. The top of the pressing pin is always in contact with the bottom surface of the locking plate. When the drive belt is not in use, the limiting groove is penetrated by the locking pin, which limits the movable block. When the lifting rod lifts the lifting plate, the connecting block and the pressing pin will move synchronously with the push plate. Move until the lifting plate rises to the designated position. The connecting block and the clamping column driven by the push plate will move to the inclined area of ​​the locking plate. The clamping column will lift the inclined part of the locking plate upward, while the horizontal part of the locking plate will rotate downward. This will cause the locking column to rotate synchronously towards the inside of the limiting groove. At this time, the moving block is no longer limited by the locking column, so that the transmission belt can be properly clamped, and the tension of the transmission belt can be adjusted. In order to ensure the normal up and down rotation of the locking column, there should be a gap between the locking column and the inner end face of the limiting groove.

[0016] As a preferred technical solution of the present invention, the clamping column includes an inner cylinder fixed on the connecting block and an outer cylinder movably sleeved outside the inner cylinder. A spring is installed inside the inner cylinder, and the top of the spring abuts against the inner top surface of the outer cylinder. When the lifting plate is lifted, the inner cylinder will spring back and lift the outer cylinder, thereby ensuring that the outer cylinder is always in contact with the locking plate, ensuring subsequent compression and adjustment of the locking plate.

[0017] As a preferred technical solution of the present invention, the main limiting rod and the auxiliary limiting rod are at the same height; when the lifting plate is lifted to the processing position by the lifting rod, the main limiting rod and the auxiliary limiting rod are flush with the top surface of the lifting plate, that is, the main limiting rod and the auxiliary limiting rod no longer protrude to the outside of the lifting plate, so as to avoid affecting the subsequent transmission, and the transmission belt moves from the sleeve to the driven wheel.

[0018] As a preferred technical solution of the present invention, the winding assembly includes a mounting plate fixed on the base plate, which is located between the two slide rails; a winding coil is rotatably disposed on the front surface of the mounting plate, and a drive motor is disposed at one end of the mounting plate away from the lifting plate, the drive motor being connected to the winding coil via a belt; a wire-passing block with holes is also fixed on the winding coil, wherein the winding coil is annular during winding, and the winding coil itself has an openable structure when winding is completed and when installing the current transformer. This structure is prior art, so it will not be described further here. During winding, copper wire is first passed through the wire-passing block with holes, and then the winding coil is rotated by the drive motor, and the current transformer sleeved with the winding coil can realize the winding process.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention modifies the conventional transmission method by innovatively adding a flexible transmission component, significantly improving the applicability and flexibility of the instrument transformer rapid winding machine. Specifically, this flexible transmission component can perform limit transmission on frame-type instrument transformers, and can switch the transmission mode of the device as needed to achieve transmission of the winding machine to the circular sensor. This design ensures a stable and precise clamping effect during the winding process of different types of instrument transformers. Through this improvement, this invention not only overcomes the limitations of existing rapid instrument transformer winding machines in terms of clamping structure, achieving universal clamping for both circular and frame-type instrument transformers, but also ensures the quality and efficiency of the winding operation, effectively addressing the shortcomings of existing structures in use, and bringing a more convenient and efficient solution to the instrument transformer manufacturing industry.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1 to 11 This invention provides a technical solution: a high-speed winding machine for current transformers, comprising...

[0045] Base plate 100; a winding assembly is provided on the top of the base plate 100;

[0046] A clamping mechanism is provided on one side of the winding assembly to clamp the current transformer and then rotate it, thereby winding copper wire onto the current transformer component to produce the finished current transformer. The clamping mechanism includes:

[0047] A ring-shaped transmission assembly; the ring-shaped transmission assembly includes at least one driving member located outside the winding assembly, and two driven members symmetrically arranged on both sides of the winding assembly; the ring-shaped transmission assembly is distributed in a three-point configuration;

[0048] A flexible transmission component is disposed below the annular transmission component; the flexible transmission component consists of a lifting plate 200 and a flexible transmission section disposed above the lifting plate 200; the flexible transmission section is connected to the drive section after horizontal sliding.

[0049] A fixed plate 300 is disposed below the lifting plate 200. A bearing plate 301 passes through the edge of the fixed plate 300 and the two are fixedly connected. The bottom end of the bearing plate 301 is fixed on the base plate 100. A slot 200e is provided on the edge of the lifting plate 200 for the bearing plate 301 to slide through.

[0050] A lifting assembly is disposed between the fixed plate 300 and the lifting plate 200; the lifting assembly performs lifting and lowering movements when the drive unit slides horizontally; when the drive unit does not slide horizontally, i.e. Figure 1 In its current state, the device can transmit data to the annular current transformer. When the drive unit slides horizontally away from the winding assembly, it transforms into... Figure 11 In this state, the flexible transmission component will replace the original ring transmission component to realize the winding processing of the frame-type transformer.

[0051] In this embodiment, the driving component in the annular transmission assembly includes a servo motor 106 and a driving wheel 107 mounted on the output end of the servo motor 106; the driven component includes a support rod 109 and a driven wheel 108 rotatably mounted on the top of the support rod 109. During the winding process of the annular current transformer, the winding assembly is first opened, and then the current transformer is placed between the driving wheel 107 and the driven wheel 108, ensuring that the current transformer does not fall off. Subsequently, the servo motor 106 and the winding assembly start synchronously. The winding assembly winds copper wire onto the current transformer, while the driving wheel 107 is driven by the servo motor 106 to rotate the current transformer, thereby winding copper wire around the annular current transformer. When installing the circular current transformer, the servo motor 106 needs to be slightly moved away from the winding assembly to facilitate the placement of the annular current transformer between the driving wheel 107 and the driven wheel 108. After placement, the servo motor 106 is pushed back into its original position, thus achieving the winding of the circular current transformer. The toroidal current transformer is locked in place, and the rotation of the subsequent drive wheel 107 drives the toroidal current transformer to rotate. The driven wheel 108 rotates under the rotation of the toroidal current transformer, and the driven wheel 108 can also clamp the toroidal current transformer. Two parallel slide rails 101 are installed on the top of the base plate 100. The top of the slide rails 101 has a strip groove. The servo motor 106 is equipped with a mounting sleeve. The two ends of the mounting sleeve are bent and overlapped on the slide rail. On the rail 101, a screw hole is provided at the bend of the mounting sleeve. In adjusting the position of the servo motor 106, the servo motor 106 with the mounting sleeve fixed is first pulled or pushed to the designated position, and then the bolt is passed through the screw hole and pressed against the strip groove at the top of the slide rail 101, thereby achieving a tight fit and fixing the position of the servo motor 106. The bottom of the support rod 109 is installed in the strip groove of the slide rail 101; the bearing plate 301 and the slide rail 101 do not contact each other.

[0052] In this embodiment, the flexible transmission unit includes a transmission belt 202. A through groove 200b is provided in the middle of the lifting plate 200. Two limiting wheels 201 are provided at the end of the lifting plate 200 away from the winding assembly. A sleeve 108a is also sleeved on the support rod 109. The sleeve 108a is located directly below the driven wheel 108. The outer diameter of the sleeve 108a is equal to that of the driven wheel 108. Because their outer diameters are equal, the sleeve 108a can be smoothly moved into the driven wheel 108 during the subsequent lifting of the transmission belt 202, and can also be smoothly moved onto the sleeve 108a during the subsequent descent. The transmission belt 202 is sleeved on the outside of the limiting wheels 201 and the sleeve 108a to realize the installation of the transmission belt 202. Multiple auxiliary limiting holes 200c are provided on the surface of the lifting plate 200 along the inner and outer walls of the transmission belt 202. The lifting plate 200 has a main limiting hole 200d at one end near the winding assembly. The transmission belt 202 is also fixed with an integrated support plate 200f at the other end near the winding assembly. Part of the transmission belt 202 overlaps with the support plate 200f. An inner bearing 108b is also sleeved on the support rod 109. The inner bearing 108b is located between the sleeves 108a. The inner bearing 108b can connect the support rod 109 and the sleeve 108a, and can also prevent the support rod 109 from driving the sleeve 108a to rotate when it rotates, thus ensuring that the transmission belt 202 is stationary when not in use. The support plate 200f is sleeved on the outside of the sleeve 108a. During the subsequent lifting of the lifting plate 200, the support plate 200f will be sleeved on the outside of the driven wheel 108. To avoid transmission obstruction, the support plate 200f and the sleeve 108a do not contact each other.

[0053] In this embodiment, a second through slot 300a is provided in the middle of the fixed plate 300. The vertical projection areas of the second through slot 300a and the first through slot 200b completely overlap. The output end of the servo motor 106 passes through the second through slot 300a and the first through slot 200b, thereby ensuring that the servo motor 106 will not be blocked by the lifting plate 200 and the fixed plate 300 when moving horizontally. Multiple auxiliary limiting rods 303 passing through the auxiliary limiting holes 200c and a main limiting rod 302 passing through the main limiting hole 200d are fixed on the top of the fixed plate 300. The main limiting rod 302 contacts the outer surface of the transmission belt 202. Through the setting of the auxiliary limiting rods 303 and the main limiting rods 302, the transmission belt 202 can be limited and stored when not in use, avoiding the phenomenon of the transmission belt 202 becoming scattered.

[0054] In this embodiment, two sets of lifting components are provided and symmetrically distributed around the center of the through slot 2 300a. Each set of lifting components includes a push plate 402 horizontally placed on top of the fixed plate 300. A connecting rod 403 is rotatably connected to one end of the push plate 402, and a lifting rod 404 is rotatably connected to the top of the connecting rod 403. The top of the lifting rod 404 fits against the bottom of the lifting plate 200, facilitating subsequent lifting of the lifting plate 200 via the lifting rod 404. A mounting seat 405 is also fixedly provided on the top of the fixed plate 300, and the mounting seat 405 is rotatably connected to the other end of the lifting rod 404. A middle plate 401 is also fixedly provided on the inner side of the push plate 402. The middle plate 401 is sleeved on the output shaft of the servo motor 106. A bearing is also provided between the middle plate 401 and the output shaft of the servo motor 106, and the servo motor 106 slides horizontally through the bearing. The servo motor 106 drives the middle plate 401 to move, while ensuring that the output shaft of the servo motor 106 does not directly contact the middle plate 401 during rotation. When the servo motor 106 slides horizontally, the output end of the servo motor 106 drives the middle plate 401 to move. The middle plate 401 synchronously drives the push plate 402 to move, and the push plate 402 pulls the bottom of the connecting rod 403 horizontally, causing the connecting rod 403 to rotate. Since the top of the lifting rod 404 is rotatably connected to the connecting rod 403, the lifting rod 404 rotates itself under the horizontal movement of the connecting rod 403, gradually changing from an inclined state to a vertical state. During this rotation and lifting process, the bottom of the lifting rod 404 rotates around the mounting base 405, and the top of the lifting rod 404 is lifted, thereby lifting the bottom of the lifting plate 200, thus achieving the lifting of the height of the lifting plate 200.

[0055] In this embodiment, two sets of tensioning components are provided on the top of the lifting plate 200. The two sets of tensioning components are symmetrically distributed around the center of the through slot 200b. Each set of tensioning components includes a fixed block 203 fixed on the top of the lifting plate 200 and a movable block 205 rotatably connected to the fixed block 203. A torsion spring 204 is also installed between the movable block 205 and the fixed block 203. A tensioning wheel 206 is installed at the end of the movable block 205 away from the fixed block 203. When the frame-type current transformer is wound through the transmission belt 202, the tensioning components will be used. In use, under the action of the rebound force of the torsion spring 204, the fixed block 203 and the movable block 205 are expanded outward, so that the tensioning wheel 206 abuts against the inner wall of the transmission belt 202. The tensioning wheel 206 abuts against the inner wall of the transmission belt 202. When the frame-type current transformer is transmitted through the transmission belt 202, refer to Figure 11The frame-type current transformer is placed in the concave area of ​​the transmission belt 202, which is the original position of the main limiting rod 302. Between the transmission belt 202 and the winding coil 105, since the frame structure has long and short sides, in order to ensure the stable limiting and transmission of the frame-type current transformer by the transmission belt 202, it is necessary to ensure that the transmission belt 202 always has tension. Therefore, the tensioning component can press the transmission belt 202 against the outside of the lifting plate 200, thereby adjusting the tension of the transmission belt 202. When the frame-type current transformer rotates, it will not contact the driven wheel 108. At this time, the driven wheel 108 mainly plays the role of transmitting power to the transmission belt 202.

[0056] In this embodiment, the top surface of the lifting plate 200 is further provided with two limiting grooves 200a. Each limiting groove 200a is respectively disposed inside each tensioning assembly. A locking assembly is also provided in the limiting groove 200a. The locking assembly includes a locking plate 503, which has a horizontal part and an inclined part. A shaft passes through the intersection of the horizontal part and the inclined part of the locking plate 503. The shaft is not shown in the figure, but the hole for the shaft to pass through at the intersection is shown in the figure. The locking plate 503 rotates around the shaft. The horizontal part of the locking plate 503 rotates from a horizontal position towards the bottom of the limiting groove 200a, and rotates upward from the bottom of the limiting groove 200a towards the water. The flat surface prevents excessive warping of the horizontal portion of the locking plate 503 due to the clamping post 502 pressing against it later. It also ensures that the clamping post 502 remains in contact with the horizontal portion of the locking plate 503 during the initial horizontal sliding phase. A locking post 504 is fixed at one end of the top surface of the horizontal portion of the locking plate 503. The top of the locking post 504 protrudes from the limiting groove 200a and abuts against the inner side of the movable block 205. When the transmission belt 202 is not in use, to ensure that the transmission belt 202 can rise synchronously with the lifting plate 200, the entire transmission belt 202 can be limited by the main limiting rod 302 and the auxiliary limiting rod 303, but should not have tension to prevent the transmission belt 202 from being overly fitted onto the sleeve 108a. Because the belt is tightly secured and cannot be separated, the locking post 504 limits the movable block 205 and the tension wheel 206, preventing the tension wheel 206 from contacting the inner wall of the transmission belt 202. The locking assembly also includes a connecting block 501 fixed to the end of the push plate 402. A pressing post 502 is installed on the connecting block 501. The top of the pressing post 502 is always in contact with the bottom surface of the locking plate 503. When the transmission belt 202 is not in use, the limiting groove 200a is penetrated by the locking post 504, and the movable block 205 is limited by the locking post 504. When the lifting rod 404 lifts the lifting plate 200, the connecting block 501 and the pressing post 502 will move synchronously with the push plate 402 until the lifting plate 200 is lifted. After the push plate 402 rises to the designated position, the connecting block 501 and the clamping column 502 driven by the push plate 402 will move to the inclined area of ​​the locking plate 503. The clamping column 502 will lift the inclined part of the locking plate 503 upward, while the horizontal part of the locking plate 503 will be rotated downward, and the locking column 504 will rotate synchronously towards the inside of the limiting groove 200a. At this time, the movable block 205 is no longer limited by the locking column 504, so that the transmission belt 202 can be properly clamped, and the tension of the transmission belt 202 can be adjusted. In order to ensure the normal up and down rotation of the locking column 504, the locking column 504 should leave a gap with the inner end face of the limiting groove 200a.

[0057] In this embodiment, the clamping column 502 includes an inner cylinder 502c fixed on the connecting block 501 and an outer cylinder 502a movably sleeved outside the inner cylinder 502c. A spring 502b is installed inside the inner cylinder 502c. The top of the spring 502b abuts against the inner top surface of the outer cylinder 502a. When the lifting plate 200 is lifted, the inner cylinder 502c will spring back and lift the outer cylinder 502a, thereby ensuring that the outer cylinder 502a is always in contact with the locking plate 503, ensuring subsequent compression and adjustment of the locking plate 503.

[0058] In this embodiment, the main limiting rod 302 and the auxiliary limiting rod 303 are at the same height. When the lifting plate 200 is lifted to the processing position by the lifting rod 404, the main limiting rod 302 and the auxiliary limiting rod 303 are flush with the top surface of the lifting plate 200. That is, the main limiting rod 302 and the auxiliary limiting rod 303 no longer protrude to the outside of the lifting plate 200, so as to avoid affecting the subsequent transmission. The transmission belt 202 moves from the sleeve 108a to the driven wheel 108.

[0059] In this embodiment, the winding assembly includes a mounting plate 104 fixed on the base plate 100, which is located between two slide rails 101. A winding coil 105 is rotatably disposed on the front surface of the mounting plate 104, and a drive motor 103 is disposed at one end of the mounting plate 104 away from the lifting plate 200. The drive motor 103 is connected to the winding coil 105 via a belt. A wire-passing block 600 with holes is also fixed on the winding coil 105. The winding coil 105 is annular during winding. When the winding is completed and when the current transformer is installed, the winding coil 105 itself has an openable structure. This structure is prior art and will not be described further here. During winding, the copper wire is first passed through the wire-passing block 600 with holes, and then the winding coil 105 is rotated by the drive motor 103. The current transformer sleeved with the winding coil 105 can realize the winding process.

[0060] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
