Description

Technical Field

[0001] This application relates to the assembly of current transformer coils, and more particularly to a current transformer coil assembly apparatus. Background Technology

[0002] A current transformer is a device that converts a large current into a small current. It is widely used in the measurement and protection of power systems. The number of turns in the coil is an important parameter of a current transformer, which directly affects its accuracy and performance. To ensure more accurate operation of the transformer in the later stages, the installation of the transformer coil is the most important step.

[0003] The existing current transformer coil is assembled by pressing with a pressing part located at the top. This assembly method is only suitable for current transformers with regular shapes. For current transformers with V-shaped iron cores, it is not possible to assemble them quickly. The operation and installation are time-consuming and laborious. In order to solve the above problems, a current transformer coil assembly device is proposed. Utility Model Content

[0004] The purpose of this application is to provide a current transformer coil assembly device with advantages such as push and press functions, which solves the problem that current transformers with V-shaped iron cores cannot be quickly assembled and that operation and installation are time-consuming and laborious.

[0005] The present application provides a current transformer coil assembly device with the following technical solution: it includes a base plate, an iron core and a frame, and a flange sheet metal, a guide seat and a limiting plate are installed and connected on the top of the base plate;

[0006] A placement groove is provided between the guide seat and the limiting plate. The placement groove is opened on the side of the guide seat. A pushing hole is opened on the side of the limiting plate. A cylinder is installed and connected to the side of the flange sheet metal. A push rod is provided inside the cylinder. A limiting block is fixedly connected to the surface of the push rod. A fixing block is fixedly connected to one end of the push rod. Two fixing plates are fixedly connected to the side of the fixing block. A roller is movably connected between the two fixing plates through a pin shaft. A through rod is provided inside the iron core. The iron core is located in the placement groove. The skeleton is sleeved on the surface of the through rod. Two grooves are provided at the bottom of the base plate. A suction cup is fixedly connected to the top of the groove.

[0007] By adopting the above technical solution, the main frame and positioning reference of the device can be formed by the flange sheet metal, guide seat, and limiting plate on the base plate. The placement groove on the side of the guide seat can accurately accommodate the iron core, ensuring its fixed position during assembly. The pushing hole of the limiting plate can provide precise guidance for the subsequent pressing action. Using a cylinder as a power source, its push rod can ensure controllable stroke through the limiting block. The fixing block, fixing plate, and roller at the end can form a pressure head. The roller can be used to contact and push the insertion rod. The iron core is pre-placed in the placement groove, and the insertion rod in the center serves as a guide shaft. When the cylinder drives the push rod forward, the roller pushes the insertion rod to deflect. After the deflection is completed, the skeleton can be fitted onto the surface of the insertion rod, thus completing the core mechanical assembly action. The two grooves at the bottom of the base plate and the suction cup at the top can form an adsorption system. When the device is placed on the worktable, the suction cup can generate suction to firmly fix the entire device, preventing displacement or vibration during assembly and ensuring operational stability.

[0008] Preferably, the roller surface is provided with a rubber pad;

[0009] By adopting the above technical solution and setting a rubber pad, elastic contact can be provided, avoiding direct rigid compression of the insertion rod by the roller. This can prevent scratches, indentations or deformation on the surface of the insertion rod. At the same time, it can also provide more reliable friction, ensuring that the roller can effectively push the insertion rod to deflect.

[0010] Preferably, the base plate has a sliding groove inside, the sliding groove is located at the top of two grooves, two fixed tubes are fixedly connected inside the sliding groove, a through hole is opened between the bottom of the fixed tube and the top of the suction cup, and a one-way air valve and an air inlet pipe are provided on the surface of the fixed tube.

[0011] By adopting the above technical solution and setting a one-way air valve, the air inside the suction cup can be discharged when the suction cup is squeezed and fixed, thereby maintaining the vacuum inside the suction cup. By setting an air inlet pipe, a physical channel for vacuum generation and transmission can be formed. Air can flow into the suction cup through the air inlet pipe, so that the suction cup will no longer adhere to the table.

[0012] Preferably, a fixing rod is fixedly connected to the inner side of the sliding groove, and two sliding cylinders are slidably connected to the surface of the fixing rod;

[0013] By adopting the above technical solution, the sliding cylinder can be slidably connected to the surface of the fixed rod to provide the function of a sliding guide rail.

[0014] Preferably, a U-shaped connecting plate is fixedly connected to the two surfaces of the slide cylinders, and a plug is fixedly connected to the side of the U-shaped connecting plate, the plug being snapped into the air intake pipe;

[0015] By adopting the above technical solution, the only external passage for air to enter the suction cup chamber can be blocked by the plug being attached to the air inlet pipe. At this time, the vacuum inside the suction cup can be maintained for a long time, which can make the equipment adsorb stably. By setting a U-shaped connecting plate and a sliding cylinder, a moving component that slides on the fixed rod can be formed. Its position change determines whether the plug is inserted into or pulled out of the air inlet pipe.

[0016] Preferably, a connecting rod is fixedly connected to the side of the U-shaped connecting plate, one end of the connecting rod slides through the side of the sliding groove and is fixedly connected to a top block;

[0017] By adopting the above technical solution, the top block can serve as a human-machine interaction point. When the device needs to be moved, people can press the top block inward to disengage the plug from the air inlet pipe, allowing air to flow into the suction cup, breaking the vacuum state, and causing the suction cup to lose its suction force. The device can then be easily lifted, and people can move the device.

[0018] Preferably, the bottom plate has a shrinkage groove on its side, the top block is located in the shrinkage groove, and the side of the top block is flush with the side of the bottom plate;

[0019] By adopting the above technical solution, the design of setting the side of the top block flush with the side of the bottom plate can avoid accidental contact. When pressing, simply press into the shrinkage groove.

[0020] Preferably, a connecting spring is fitted on the surface of the fixing rod, and the two ends of the connecting spring are respectively fixedly connected to the side of the U-shaped connecting plate and the inside side of the sliding groove;

[0021] By adopting the above technical solution and by setting a connecting spring, when the operator releases the top block, the compressed connecting spring releases its elasticity, which can push the U-shaped connecting plate to move along the direction of the fixed rod and slide back to its original position. The return movement of the U-shaped connecting plate can drive the plug to automatically re-insert and seal the air intake pipe.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This transformer coil assembly device uses a base plate with flange sheet metal, guide seat, and limiting plate to form the main frame and positioning reference. The placement groove on the side of the guide seat can accurately accommodate the iron core, ensuring its fixed position during assembly. The pushing hole of the limiting plate can provide precise guidance for subsequent pressing actions. A cylinder is used as a power source, and its push rod is controlled by the limiting block. The fixing block, fixing plate, and roller at the end form a pressing head. The roller can contact and push the insertion rod. The iron core is pre-placed in the placement groove, and the insertion rod in the center acts as a guide shaft. When the cylinder drives the push rod forward, the roller pushes the insertion rod to deflect. After the deflection is complete, the frame can be fitted onto the surface of the insertion rod, thus completing the core mechanical assembly action. The two grooves at the bottom of the base plate and the suction cup at the top form an adsorption system. When the device is placed on the worktable, the suction cup can generate suction to firmly fix the entire device, preventing displacement or vibration during assembly and ensuring operational stability.

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0035] Example 1: A transformer coil assembly device, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a base plate 1, an iron core 3 and a frame 4. The top of the base plate 1 is equipped with a flange sheet metal 101, a guide seat 102 and a limit plate 103.

[0036] A placement groove 104 is provided between the guide seat 102 and the limiting plate 103. The placement groove 104 is opened on the side of the guide seat 102. A push hole 105 is opened on the side of the limiting plate 103. A cylinder 2 is installed and connected to the side of the flange sheet metal 101. A push rod 201 is provided inside the cylinder 2. A limiting block 202 is fixedly connected to the surface of the push rod 201. A fixing block 203 is fixedly connected to one end of the push rod 201. Two fixing plates 204 are fixedly connected to the side of the fixing block 203. The two fixing plates 204 are connected to each other. A roller 205 is movably connected via a pin shaft. A through-rod 301 is installed inside the iron core 3, which is positioned within a placement groove 104. A frame 4 is fitted onto the surface of the through-rod 301. Two grooves 106 are provided at the bottom of the base plate 1, with suction cups 1019 fixedly connected to the top of each groove. The main frame and positioning reference of the device can be formed by the flange sheet metal 101, guide seat 102, and limiting plate 103 on the base plate 1. The placement groove 104 on the side of the guide seat 102 can precisely accommodate the iron core 3. To ensure its fixed position during assembly, the push hole 105 of the limiting plate 103 provides precise guidance for subsequent pressing actions. Using the cylinder 2 as a power source, its push rod 201 can ensure controllable stroke through the limiting block 202. The end fixing block 203, fixing plate 204 and roller 205 can form a pressing head. The roller 205 can be used to contact and push the insertion rod 301. The iron core 3 is pre-placed in the placement groove 104, and the insertion rod 301 in the center serves as a guide shaft. When the cylinder 2 drives the push rod 201 forward, the roller 205 pushes the insertion rod 301 to deflect. After the deflection is completed, the frame 4 can be fitted onto the surface of the insertion rod 301, thereby completing the core mechanical assembly action. The two grooves 106 at the bottom of the base plate 1 and the suction cup 1019 at the top can form an adsorption system. When the device is placed on the workbench, the suction cup 1019 can generate suction to firmly fix the entire device, preventing displacement or vibration during assembly and ensuring operational stability.

[0037] Please see Figure 3The roller 205 is provided with a rubber pad 206. By providing the rubber pad 206, elastic contact can be provided, avoiding the roller 205 from directly and rigidly squeezing the insertion rod 301. This can prevent scratches, indentations or deformation on the surface of the insertion rod 301. At the same time, it can also provide more reliable friction, ensuring that the roller 205 can effectively push the insertion rod 301 to deflect.

[0038] Please see Figure 5The base plate 1 has a sliding groove 107 inside, which is located at the top of two recesses 106. Two fixing tubes 109 are fixedly connected inside the sliding groove 107. A through hole 108 is formed between the bottom of the fixing tube 109 and the top of the suction cup 1019. A one-way valve 1010 and an air inlet pipe 1011 are provided on the surface of the fixing tube 109. By setting the one-way valve 1010, air inside the suction cup 1019 can be expelled when the suction cup 1019 is squeezed and fixed, thus maintaining the vacuum level inside the suction cup 1019. The air inlet pipe 1011 forms a physical channel for vacuum generation and transmission, allowing air to flow into the suction cup 1019, preventing the suction cup 1019 from adhering to the table and allowing it to slide. A fixed rod 1012 is fixedly connected to the inner side of the moving groove 107. Two sliding cylinders 1015 are slidably connected to the surface of the fixed rod 1012, providing a sliding guide. A U-shaped connecting plate 1013 is fixedly connected to the surface of the two sliding cylinders 1015. A plug 1014 is fixedly connected to the side of the U-shaped connecting plate 1013. The plug 1014 is engaged in the air inlet pipe 1011, blocking the only external passage for air to enter the suction cup 1019 chamber. At this time, the vacuum inside the suction cup 1019 is maintained for a long time, allowing the equipment to stably adsorb. By setting the U-shaped connecting plate 1013 and the sliding cylinders 1015, a system can be formed on the fixed rod 1012. The positional change of the sliding component on 012 determines whether the plug 1014 is inserted into or removed from the air inlet pipe 1011. A connecting rod 1020 is fixedly connected to the side of the U-shaped connecting plate 1013. One end of the connecting rod 1020 slides through the side of the sliding groove 107 and is fixedly connected to a top block 1018. By setting the top block 1018, it can become a human-machine interaction point. When the device needs to be moved, people can press the top block 1018 inward to disengage the plug 1014 from the air inlet pipe 1011, allowing air to flow into the suction cup 1019, breaking the vacuum state, causing the suction cup 1019 to lose its suction force, and the device can be easily lifted, allowing people to move the device. A contraction groove 1017 is opened on the side of the base plate 1, and the top block 1018 is in a contracted state. Inside the groove 1017, the side of the top block 1018 is flush with the side of the bottom plate 1. This design avoids accidental contact. When pressing, simply press into the shrink groove 1017. A connecting spring 1016 is fitted on the surface of the fixing rod 1012. The two ends of the connecting spring 1016 are fixedly connected to the side of the U-shaped connecting plate 1013 and the inside side of the sliding groove 107, respectively. By setting the connecting spring 1016, when the operator releases the top block 1018, the compressed connecting spring 1016 releases its elasticity, which can push the U-shaped connecting plate 1013 to move along the direction of the fixing rod 1012 and slide back to its original position. The return movement of the U-shaped connecting plate 1013 can drive the plug 1014 to automatically re-insert and seal the air intake pipe 1011.

[0039] The implementation principle of this application embodiment is as follows: When in use, people place the device on the table. After placement, people press down on the device, which allows the air in the suction cup 1019 to be discharged through the one-way air valve 1010, thereby maintaining the vacuum in the suction cup 1019 and allowing the suction cup 1019 to adhere to the table, thus forming an adsorption system. When the device is placed on the workbench, the suction cup 1019 can generate suction force to firmly fix the entire device, preventing displacement or vibration during assembly and ensuring operational stability. After completion, the device can be used.

[0040] When it is necessary to assemble the iron core 3 and the frame 4, people put the iron core 3 into the placement slot 104. After the placement is completed, the cylinder 2 is started, which can push the roller 205 to move. By moving the roller 205, the insertion rod 301 can be shifted. After the shift is completed, people can put the frame 4 on the surface of the insertion rod 301, thus completing the core mechanical assembly action.

[0041] When the device needs to be lifted, people press the top block 1018, which can disengage the plug 1014 from the air inlet pipe 1011, allowing air to flow into the suction cup 1019, breaking the vacuum state, causing the suction cup 1019 to lose its suction force, and the device can be easily lifted, allowing people to move the device.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
