Description

Technical Field

[0001] This application relates to the field of coil winding technology, and in particular to a CNC winding machine that facilitates the clamping of irregularly shaped coils. Background Technology

[0002] A voltage transformer is a very important current measurement sensor that can span low-voltage and high-voltage power supply systems, reducing the voltage of high-voltage circuits to a lower value to facilitate measurement and protection by instruments and protection devices. The coil is an important component of the voltage transformer, and its quality and performance directly affect the effectiveness of the voltage transformer.

[0003] Existing coils are usually made by winding enameled copper wire onto an iron core using a winding machine. The coil shape is usually circular, but in some special fields, rectangular, sector-shaped, and other irregular coils are used. When winding irregular coils, a clamp with a belt is usually used to fix the iron core. During fixing, the worker places the iron core on the belt clamp, then manually pulls the belt to wind the belt around the rotating roller and tighten it to fix the iron core.

[0004] The existing technical solutions mentioned above have the following drawbacks: when continuously winding multiple rectangular coils, workers need to repeatedly pull the belt manually to load and unload the materials, resulting in low work efficiency. Utility Model Content

[0005] This application provides a CNC winding machine that facilitates the loading and unloading of materials by workers and improves the working efficiency of winding irregularly shaped coils.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A CNC winding machine for easily clamping irregularly shaped coils includes a base, a head mounted on the base, a mounting plate on the base, a winding groove on the mounting plate, and a notch for the head to rotate. A drive guide wheel, a driven guide wheel, and a limit guide wheel are rotatably mounted on the mounting plate. At least two drive guide wheels and at least two driven guide wheels are spaced apart, arranged in a rectangular pattern. At least two limit guide wheels are spaced apart. A push plate is slidably mounted on the mounting plate, a connecting rod is fixedly connected to the push plate, and an electric push rod is mounted on the mounting plate. The output end of the electric push rod is connected to the connecting rod. A tensioning guide wheel is rotatably mounted on the push plate. A belt for fixing the iron core is wound around the driving guide wheel, the driven guide wheel, the limiting guide wheel, and the tensioning guide wheel. The belt enters the winding groove between the two limiting guide wheels. The section of the belt in the winding groove is U-shaped and wraps around the outside of the iron core. The distance between the two limiting guide wheels is less than the diameter of the iron core. A limiting belt is fixed to the belt. A section of the limiting belt is bent into an arc shape towards the iron core. The outer walls of the driving guide wheel, the driven guide wheel, the limiting guide wheel, and the tensioning guide wheel are all machined to form an arc-shaped surface that fits with the belt and the limiting belt.

[0008] By adopting the above technical solution, the belt inside the winding groove is U-shaped and wraps around the outside of the iron core. The distance between the limiting guide wheels is less than the diameter of the iron core, so that the opening of the U-shaped section of the belt is smaller than the outer diameter of the iron core, thereby restricting the movement of the iron core within the winding groove. The side of the limiting belt away from the belt bends into an arc shape towards the iron core to wrap around the outer edge of the iron core, preventing the iron core from detaching from the U-shaped section of the belt. The output end of the electric push rod extends, which can tension the belt and the limiting belt, thus tensioning a section of the belt inside the winding groove to wrap around the wire to be wound. The iron core is fixed in the winding slot by a belt located inside the winding slot. This ensures that the iron core is firmly clamped on the winding machine. The electric push rod is controlled to loosen the belt again, making it easier for the operator to remove the wound irregular coil. Then, the iron core to be wound is placed in the winding slot, with the belt wrapping around the iron core in a U-shape. This simplifies the manual operation steps when winding multiple irregular coils continuously, facilitates loading and unloading, and improves the work efficiency of winding irregular coils.

[0009] Optionally, the mounting plate is provided with limiting holes for fixing the limiting guide wheel, and multiple limiting holes are provided at intervals.

[0010] By adopting the above technical solution, changing the installation of the limiting roller in different limiting holes, and adjusting the distance between the limiting roller and the machine head, the distance of the belt opening in the U-shaped section in the winding groove when fixing the iron core can be adjusted. The size of the U-shaped opening of the belt can be adjusted according to the size of the iron core, increasing the applicability of the winding machine when winding irregular iron cores.

[0011] Optionally, the push plate is provided with mounting holes for fixing the tension guide wheel, and multiple mounting holes are spaced apart.

[0012] By adopting the above technical solution, changing the installation of the tensioning roller in different mounting holes, and adjusting the distance between the tensioning roller and the machine head, the length of the belt segment in the winding groove when fixing the iron core can be adjusted. The length of the belt when tensioning can be adjusted according to the size of the iron core, thereby increasing the applicability of the winding machine when winding irregular iron cores.

[0013] Optionally, a rubber layer is fixedly attached to the driving guide wheel, the driven guide wheel, the limiting guide wheel, and the tensioning guide wheel.

[0014] By adopting the above technical solution, the rubber layer can increase the friction between the guide wheel and the belt and the limiting belt, reduce the danger of belt slippage causing the iron core to rotate and jam, and ensure the safety and stability of the winding machine operation.

[0015] Optionally, a pressure plate is fixedly connected to the push plate.

[0016] By adopting the above technical solution, the pressure plate moves along the slide groove to the top of the winding groove as the push plate moves. At this time, the pressure plate is located above the iron core. When the winding machine winds the wire, the tension of the enameled copper wire may pull the iron core to shake in the winding groove, or even cause the side of the iron core away from the notch to come out of the winding groove. The pressure plate can prevent the iron core from moving away from the mounting groove, ensuring that the iron core will not come out of the mounting groove during winding.

[0017] Optionally, wear-resistant plates are fixedly connected to both the pressure plate and the winding groove.

[0018] By adopting the above technical solution, the wear-resistant plates on the pressure plate and in the winding groove can reduce the wear of the pressure plate and the winding groove, reduce the risk of the iron core not rotating smoothly due to the wear of the pressure plate and the winding groove, and ensure the safety and stability of the winding machine.

[0019] Optionally, a support rod is fixedly connected to the mounting plate, and at least two support rods are spaced apart, with the length of the support rod closer to the machine head being greater than the length of the other support rod.

[0020] By adopting the above technical solution, the mounting plate can be tilted so that when the belt is loosened after winding, the iron core slides away from the machine head in the mounting groove, allowing the loose belt to enter the winding groove. This makes it easier for workers to remove the wound irregular coils, facilitating loading and unloading and improving the work efficiency of winding irregular coils.

[0021] Optionally, a rubber pad is fixed to the bottom of the base.

[0022] By adopting the above technical solution, the rubber pad can increase the stability of the machine base, reduce the slippage of the machine base caused by vibration during the operation of the winding machine, and ensure the safety and stability of the winding machine during operation.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up an installation plate, push plate, and belt, the iron core is securely clamped on the winding machine. The electric push rod is controlled to loosen the belt again, making it easier for the workers to take out the wound irregular coils. Then, the iron core to be wound is placed in the winding slot, so that the belt wraps around the iron core in a U-shape. This simplifies the manual operation steps for workers when winding multiple irregular coils continuously, facilitates loading and unloading, and improves the work efficiency of winding irregular coils.

[0025] 2. By adding a rubber layer, the friction between the guide wheel and the belt and limit belt can be increased, reducing the risk of belt slippage causing the iron core to rotate and jam, thus ensuring the safety and stability of the winding machine.

[0026] 3. By incorporating wear-resistant plates, wear on the pressure plate and winding groove can be reduced, thereby mitigating the risk of uneven core rotation caused by wear on the pressure plate and winding groove, and ensuring the safety and stability of the winding machine.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a CNC winding machine that facilitates the clamping of irregularly shaped coils, referring to... Figure 1 and Figure 2The winding machine includes a base 1, with rubber pads 11 bonded to the bottom of the base 1. Four rubber pads 11 are arranged in a rectangle on the bottom surface of the base. A head 2 is installed on one side of the base 1. A mounting plate 3 is provided on the base 1. The mounting plate 3 has a rectangular surface, and four support rods 31 are integrally formed on the lower surface of the mounting plate 3. The four support rods 31 are distributed in a rectangle on the lower surface of the mounting plate 3. The length of the two support rods 31 closer to the head 2 is greater than the length of the two support rods 31 farther away from the head 2.

[0033] Reference Figure 1 and Figure 2 The mounting plate 3 has a winding groove 32 for accommodating the iron core near the head 2. A notch for the head 2 to rotate is also provided on the side of the mounting plate 3 near the head 2, and this notch communicates with the winding groove 32. A drive guide wheel 33, a driven guide wheel 34, and a limit guide wheel 35 are rotatably mounted on the mounting plate 3. Two drive guide wheels 33 are spaced apart and symmetrically arranged on the section of the mounting plate 3 away from the head 2. A motor is installed inside the base 1, and the motor's output shaft is connected to the shaft of one of the drive wheels via a coupling. In this embodiment, the motor and... The couplings are not shown. Two driven guide wheels 34 are spaced apart and symmetrically arranged on one side of the mounting plate 3 near the machine head 2. Two drive guide wheels 33 and two driven guide wheels 34 are arranged in a rectangle on the mounting plate 3. A limiting hole for fixing the limiting guide wheel 35 is opened in the section of the mounting plate 3 near the machine head 2. Multiple limiting holes are spaced apart along the edge of the plate surface of the section of the mounting plate 3 near the machine head 2. Two limiting guide wheels 35 are spaced apart and are located on both sides of the notch in the section of the mounting plate 3 near the machine head 2.

[0034] Reference Figure 1 and Figure 2 The mounting plate 3 has a groove at a distance away from the machine head 2. A strip hole is opened at the bottom of the groove. A push plate 4 is slidably installed in the groove. The surface of the push plate 4 is rectangular. A connecting rod is integrally formed on the side of the push plate 4 facing the strip hole. The end of the connecting rod away from the push plate 4 extends out of the bottom surface of the mounting plate 3 from the strip hole. An electric push rod 41 is installed at the bottom of the mounting plate 3. The output end of the electric push rod 41 is fixed to the connecting rod by bolts. A tension guide wheel 42 is rotatably installed on the push plate 4. The push plate 4 has mounting holes for fixing the tension guide wheel 42. Multiple mounting holes are spaced apart along the length of the push plate 4.

[0035] Reference Figure 1 and Figure 2A belt 5 for fixing the iron core is wound around the driving guide wheel 33, driven guide wheel 34, limiting guide wheel 35, and tensioning guide wheel 42. The belt 5 enters the winding groove 32 between the two limiting guide wheels 35. The belt 5 in the winding groove 32 is U-shaped and wraps around the outside of the iron core. The distance between the two limiting guide wheels 35 is less than the diameter of the iron core, so that the opening of the U-shaped section of the belt 5 is smaller than the outer diameter of the iron core, thereby restricting the movement of the iron core in the winding groove 32. Both sides of the belt 5 are integrally formed with limiting bands 51. The side of the positioning belt 51 away from the belt 5 bends into an arc shape towards the iron core to wrap around the outer edge of the iron core and prevent the iron core from coming out of the U-shaped section of the belt 5. The peripheral walls of the driving guide wheel 33, the driven guide wheel 34 and the limiting guide wheel 35 are recessed inward to fit the arc shape of the belt 5 and the limiting belt 51. The peripheral wall of the tensioning guide wheel 42 protrudes outward to fit the arc shape of the belt 5 and the limiting belt 51. The outer walls of the driving guide wheel 33, the driven guide wheel 34, the limiting guide wheel 35 and the tensioning guide wheel 42 are all bonded with a rubber layer.

[0036] Reference Figure 2 and Figure 3 A pressure plate 6 is bolted to the surface of the push plate 4 near the head 2. The surface of the pressure plate 6 is U-shaped and the opening faces the head 2. One part of the pressure plate 6 extends out of the push plate 4 and is located above the winding groove 32. Wear-resistant plates are glued to the bottom of the winding groove 32 and the side of the pressure plate 6 facing the winding groove 32. A protective cover 7 is bolted to the side of the mounting plate 3 away from the base 1.

[0037] When using this winding machine to clamp the iron core, place the iron core to be wound in the winding groove 32 of the mounting plate 3. The belt 5 enters the winding groove 32 between the two limiting guide rollers 35, forming a U-shaped section that wraps around the iron core. The belt 5 in the winding groove 32 wraps around the outside of the iron core in a U-shape. The distance between the limiting guide rollers 35 is less than the diameter of the iron core, so that the opening of the U-shaped section of the belt 5 is smaller than the outer diameter of the iron core, thus restricting the movement of the iron core within the winding groove 32. The side of the limiting belt 51 away from the belt 5 bends into an arc shape towards the iron core to further wrap the iron core. The outer edge of the core restricts the iron core from detaching from the belt 5 in a U-shape. The output end of the control electric push rod 41 extends to drive the connecting rod and push plate 4 to move towards the machine head 2 in the slide groove. The tensioning roller moves towards the machine head 2 to tension the belt 5 and the limiting belt 51, so that a section of belt 5 in the winding groove 32 is tensioned to wrap the iron core to be wound. The iron core is fixed in the winding groove 32 by the section of belt 5 located in the winding groove 32, so as to ensure that the iron core is firmly clamped on the winding machine.

[0038] After fixing the iron core, move the machine head 2 to the winding position and prepare for winding. Start the motor to drive the drive guide wheel 33 connected to it to rotate. The drive guide wheel 33 drives the belt 5 and the limit belt 51 to rotate. A section of belt 5 in the winding groove 32 wraps around the iron core and rotates, cooperating with the machine head 2 to wind the enameled copper wire onto the iron core.

[0039] After winding is completed, the output end of the control electric push rod 41 retracts and drives the push plate 4 to move away from the machine head 2 along the slide groove. The tension guide wheel 42 moves away from the machine head 2, so that the belt 5 is relaxed again, making it easier for the workers to take out the wound irregular coil. Then, the iron core to be wound is placed in the winding groove 32, so that the belt 5 wraps around the iron core in a U-shape. This simplifies the manual operation steps of the workers when winding multiple irregular coils continuously, facilitates the loading and unloading of materials, and improves the working efficiency of winding irregular coils.

[0040] When using this winding machine to wind coils of different sizes, by changing the installation of the tension roller in different mounting holes and adjusting the distance between the tension roller and the machine head 2, the length of the belt 5 in the U-shaped section in the winding groove 32 when the iron core is fixed can be adjusted. The length of the belt 5 when tensioned can be adjusted according to the size of the iron core, increasing the applicability of the winding machine when winding irregular iron cores.

[0041] When using this winding machine to wind coils of different sizes, by changing the installation of the limiting rollers in different limiting holes and adjusting the distance between the limiting rollers and the machine head 2, the opening distance of the belt 5 in the U-shaped section of the winding groove 32 when fixing the iron core can be adjusted. The size of the opening of the U-shaped section of the belt 5 can be adjusted according to the size of the iron core, increasing the applicability of the winding machine when winding irregular iron cores.

[0042] When using this winding machine to wind irregularly shaped coils, the pressure plate 6 moves along the slide along the push plate 4 to above the winding groove 32. At this time, the pressure plate 6 is located above the iron core. When the winding machine winds the wire, the tension of the enameled copper wire may pull the iron core to shake in the winding groove 32, or even cause the side of the iron core away from the notch to come out of the winding groove 32. The pressure plate 6 can prevent the iron core from moving away from the mounting groove, ensuring that the iron core will not come out of the mounting groove during winding.

[0043] When using this winding machine to wind irregularly shaped coils, the protective cover 7 can prevent the loose belt 5 from falling off and prevent foreign objects from entering between the belt 5 and the drive guide wheel 33 or the driven guide wheel 34, reducing the risk of foreign objects causing the belt 5 to jam or even be damaged.

[0044] When using this winding machine to wind irregularly shaped coils, the rubber layer on the outer walls of the drive guide wheel 33, driven guide wheel 34, limit guide wheel 35, and tension guide wheel 42 increases the friction between the guide wheels and the belt 5 and limit belt 51, reducing the risk of the iron core rotating and jamming due to belt 5 slippage, thus ensuring the safety and stability of the winding machine's operation. The wear-resistant plates on the pressure plate 6 and inside the winding groove 32 reduce wear on the pressure plate 6 and winding groove 32, lowering the risk of the iron core rotating unevenly due to wear, and ensuring the safety and stability of the winding machine's operation.

[0045] When using this winding machine to wind irregularly shaped coils, the lengths of the two support rods 31 closer to the machine head 2 are greater than the lengths of the two support rods 31 farther from the machine head 2. This allows the mounting plate 3 to be tilted, so that after winding, when the belt 5 loosens, the iron core slides away from the machine head 2 within the mounting groove, allowing the loose belt 5 to enter the winding groove 32. This facilitates the removal of the wound irregularly shaped coil by the operator, making loading and unloading easier and improving the efficiency of winding irregularly shaped coils. The rubber pad 11 at the bottom of the machine base 1 increases the stability of the machine base 1, reduces the slippage of the machine base 1 caused by vibrations during operation, and ensures the safety and stability of the winding machine during operation.

[0046] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
