Description

Technical Field

[0001] The present application relates to the technical field of mutual inductors, and in particular to an assembly device for mutual inductors. Background Art

[0002] Transformer is a general term for current transformer and voltage transformer, which can convert high voltage into low voltage and high current into low current, and is used for measurement or protection system. Its main function is to convert high voltage or high current into standard low voltage or standard low current in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, transformer can also be used to isolate high voltage system to ensure the safety of people and equipment.

[0003] In the related art, reference can be made to the Chinese patent with authorization announcement number CN218939410U, which is a mutual inductor assembly structure, including a housing 100, a terminal block 200, a mutual inductance coil 300, a phase busbar 400 and a phase connecting pin 500. When the phase busbar 400 is bent, the middle part of the phase busbar 400 is U-shaped and includes a horizontal plate 410 and a vertical plate 420 located on both sides of the horizontal plate 410. The ends of the two vertical plates 420 are bent outward with a bending portion 430. The phase connecting pin 500 is riveted or welded to one of the vertical plates 420, and the mutual inductance coil 300 is installed on the other vertical plate 420.

[0004] When assembling the mutual inductor, the phase connecting pin needs to be fixedly installed on one of the vertical plates, and then the mutual inductance coil is installed on the bent portion. When installing the phase connecting pin, the phase busbar and the phase connecting pin need to be positioned by a clamp, and then they are welded or riveted fixed by a riveting machine or a welding machine. During the fixing process, the vertical plate and the bent portion on the other side may easily interfere with the operation of the riveting machine or the welding machine, and after being bent to form the vertical plate and the horizontal plate, they need to be removed again and installed on a new clamp and the phase connecting pin for positioning, which greatly prolongs the time spent on the assembly process, and the re-positioning also reduces the positioning accuracy, thereby reducing the assembly efficiency and quality of the mutual inductor. Summary of the invention

[0005] In order to improve the assembly efficiency and quality of a mutual inductor, the present application provides an assembly device for a mutual inductor.

[0006] The present application provides an assembly device for a transformer, which adopts the following technical solution:

[0007] An assembly device for a mutual inductor comprises a base and an assembly device arranged on the base, wherein the assembly device comprises:

[0008] A fixing seat, which is arranged on the machine base and has a plug-in slot for plugging and matching with the phase busbar;

[0009] A pressing assembly, which is arranged on the fixing seat and is used to position the phase busbar located on the plug-in slot;

[0010] A bending mechanism, which is arranged on a fixing seat and is used to limit and bend the phase busbar into two sections to form a horizontal plate and one of the vertical plates;

[0011] The clamping mechanism is arranged on the fixing seat and is used to clamp the phase line connecting needle; after the bending mechanism is bent, the limiting of the phase line busbar is released so that the phase line connecting needle is pressed against the phase line busbar for positioning under the action of the gravity of the clamping mechanism.

[0012] By adopting the above technical solution, one end of the phase busbar is plugged and installed on the plug-in slot for preliminary positioning, the pressing assembly is started to press on the phase busbar for positioning, and the bending mechanism is started to limit the phase busbar into two sections. The bending mechanism first limits the side of the phase busbar close to the plug-in slot, and then the bending mechanism is rotated for the first time to bend to form a vertical plate. The bending mechanism is started to limit the latter part of the phase busbar, and then the bending mechanism releases the limit on the side of the phase busbar close to the plug-in slot, so that a part of the phase busbar close to the plug-in slot is exposed, and the phase connecting pin is installed on the clamping mechanism. The phase connecting needle is pressed against the vertical plate under the action of gravity of the clamping mechanism for positioning, and then riveted or welded, so that the phase connecting needle is fixedly installed on the phase busbar; the bending mechanism is started to limit the phase busbar in two sections, and the bending mechanism rotates for the second time to bend the phase busbar to form a horizontal plate, and the bending mechanism releases the limit on the phase busbar, and then the phase busbar can be removed, and then the other end of the phase busbar is plugged into the plug-in slot, and the bending mechanism starts bending twice, and finally two vertical plates and two bent parts are formed, so as to complete the fixation of the phase busbar and the phase connecting needle.

[0013] The bending mechanism can realize two bending of the phase busbar without changing the clamp. At the same time, after the first bending, the bending mechanism limits and positions the other parts of the phase busbar, so that the vertical plate part can continue to be positioned after bending, reducing the probability of rebound and deformation after bending. At the same time, the phase connecting pin is limited by the clamping mechanism, and under the action of gravity, the phase connecting pin is pressed against the phase busbar for positioning. Therefore, no matter what the size of the phase connecting pin is, positioning can be achieved, which greatly improves the convenience and accuracy of the positioning process, thereby greatly improving the assembly efficiency and quality of the transformer assembly process.

[0014] Optionally, the bending mechanism includes:

[0015] A first bending assembly and a second bending assembly, wherein the first bending assembly is arranged on a fixed seat and is used to bend the phase busbar to form a vertical plate, and the second bending assembly is arranged on the first bending assembly and is used to bend the phase busbar to form a horizontal plate portion after the first bending assembly is bent; when the first bending assembly completes bending, the second bending assembly limits the phase busbar and then the first bending assembly unlocks the limit on the phase busbar.

[0016] By adopting the above technical scheme, the first bending component starts to limit the phase busbar and then rotates to bend it, the second bending component starts to limit and position the phase busbar, the first bending component releases the limit on the phase busbar to expose the phase busbar, and then the phase connecting pin is fixedly connected to the vertical plate. During the connection process, the second bending component is used to position the phase busbar. After the connection is completed, the first bending component continues to limit and position the phase busbar, the second bending component rotates to bend the phase busbar, and then the other end of the phase busbar is plugged and installed on the plug-in slot, and then the first bending component is limited and rotated to perform the first bending, and the second bending component is limited and rotated to perform the second bending, and finally a horizontal plate, two vertical plates and two bending parts are obtained, thereby completing the production of the phase busbar and the fixation of the phase busbar and the phase connecting pin, thereby improving the assembly efficiency and accuracy of the mutual inductor.

[0017] Optionally, the first bending component includes:

[0018] A first limiting seat, wherein the first limiting seat is rotatably arranged on the fixed seat and the rotation direction is perpendicular to the length direction of the phase busbar;

[0020] A first driving member and a second driving member, wherein the first driving member and the second driving member are respectively arranged on the fixing seat and the first limiting seat and are respectively used to drive the first limiting seat and the second limiting seat to rotate.

[0021] By adopting the above technical solution, when the phase busbar is plugged and installed on the plug-in slot, the phase busbar is positioned against the first limit seat, and the second driving member drives the second limit seat to press against the first limit seat to form a limit chamber. The limit chamber can limit the phase busbar, and the second bending assembly also limits the phase busbar. The first driving member starts to drive the first limit seat to rotate, so as to achieve bending of the phase busbar. After the bending is completed, the second driving member drives the second limit seat away from the first limit seat to expose the phase busbar. At this time, the second bending assembly continues to limit the phase busbar, and then the phase connecting pin is installed. After the installation is completed, the second limit seat continues to rotate and press against the first limit seat to continue to limit the phase busbar, and the second bending assembly rotates to bend the phase busbar.

[0022] Optionally, the pressing component includes:

[0023] A pressing plate, which is slidably disposed on the fixing seat in a direction close to or away from the plug-in slot and is used to press against the phase busbar for positioning;

[0024] The telescopic member is arranged on the fixing seat and is used for driving the pressing plate to move.

[0025] By adopting the above technical solution, the telescopic member is started to drive the pressure plate to move, so that the pressure plate is pressed against the phase busbar for positioning, or the pressure plate is unlocked away from the phase busbar.

[0026] Optionally, the fixing seat is provided with a slot which is plugged into and matched with the plug-in busbar, and when the phase busbar is plugged into and matched with the plug-in slot and the slot, they are in a perpendicular state to each other.

[0027] By adopting the above technical scheme, when the phase busbar is bent, the operation method is normal, and when the phase busbar is straight, the phase busbar is plugged and installed on the slot for positioning, and then the phase connecting pin is limited and positioned by the clamping mechanism. The phase connecting pin is pressed against the phase busbar under the action of gravity of the clamping mechanism for positioning, and then welding or riveting can be carried out, thereby realizing the assembly of more types of phase busbars, especially when encountering small batches and different types of phase busbars, there is no need to frequently replace the clamp, which can greatly improve the assembly efficiency and quality, and improve the assembly efficiency and quality of the transformer.

[0028] Optionally, a first mounting block and a second mounting block are detachably mounted on the fixing seat, the plug slot and the slot are respectively provided on the first mounting block and the second mounting block, and the first mounting block is provided with a through slot for the pressure plate to pass through.

[0029] By adopting the above technical solution, when the bending size of the phase busbar is different, different first mounting blocks or second mounting blocks are replaced, so that the phase busbars of different sizes can be bent, thereby improving the adaptability of this structure, improving the assembly efficiency and quality of the mutual inductor, and reducing the assembly cost; at the same time, the pressure plate can be moved away from the outside of the first mounting block through the groove, which improves the convenience of replacing the first mounting block and the second mounting block.

[0030] Optionally, the clamping mechanism includes:

[0031] A counterweight block, the counterweight block is vertically slidably mounted on a fixed seat;

[0032] A positioning assembly, which is arranged on the fixing seat and is used to position the counterweight block and to provide buffering when the counterweight block drives the phase line connection needle to move downward;

[0033] Two connection blocks, the two connection blocks are connected to each other and are slidably arranged on the counterweight block so that one of the connection blocks is aligned with the phase busbar, and the phase connection pin is inserted and arranged on one of the connection blocks for positioning;

[0034] A limiting assembly is arranged on the counterweight block and is used to locate the positions of the two connecting blocks.

[0035] By adopting the above technical scheme, in the initial state, the two connecting blocks are located above the phase busbar, and the positioning component positions the counterweight block and the two connecting blocks. After the first bending of the bending component is completed and the limit of the phase busbar is released, one end of the phase connecting pin is plugged and installed on one of the connecting blocks, and then the positioning component is released. Under the action of gravity, the counterweight block drives the phase connecting pin to press against the phase busbar for positioning, and then welding or riveting can be performed to fix the phase connecting pin and the phase busbar. Then the second bending is continued. After the bending is completed, the limit of the phase busbar is released, and then the phase busbar and the counterweight block are pulled upward. The counterweight block moves upward to drive the phase connecting pin to move, so that the phase busbar is detached from the plug-in slot, and then the phase busbar can be removed.

[0036] When switching between two different types of phase busbars, straight and curved, the limit assembly is unlocked, pushing the two connecting blocks to move so that the other connecting block is aligned with the phase busbar, and then assembly continues. In this way, the assembly of different types of phase busbars can be adapted through the same clamping mechanism, thereby improving the efficiency and accuracy of the assembly process of different types of phase busbars. At the same time, the positioning assembly can also buffer the downward movement of the phase connecting pin driven by the counterweight block, reducing the probability of impact damage to the phase connecting pin, and improving the assembly efficiency and quality of the transformer.

[0039] A positioning screw is threadedly connected to a fixing seat. When the counterweight needs to be positioned, the positioning screw pushes the positioning spring piece to press against the limiting groove for positioning.

[0040] By adopting the above technical scheme, when the counterweight needs to be positioned, the positioning screw is turned to push the positioning spring piece against the positioning slot for positioning; and when the counterweight needs to be lowered, the positioning screw is turned away from the positioning spring piece, and the counterweight pushes the positioning spring piece away from the counterweight under the action of gravity, so that the positioning spring piece moves from the previous limit slot to the next limit slot. Therefore, the positioning spring piece can buffer the descent of the counterweight, thereby reducing the probability of the phase line connecting pin being damaged by collision with the phase line busbar after moving downward, and the positioning spring piece cooperates with the positioning slot to increase the position range of the counterweight after positioning, thereby improving the convenience during positioning, thereby improving the assembly efficiency and quality of the transformer.

At this time, one of the connecting blocks is aligned with the phase busbar located below. When replacement is required, the two connecting blocks are pushed back so that the other connecting block is pressed against the other limit block for positioning. At the same time, the magnet sheet is also adsorbed on the connecting block for positioning, so that the other connecting block is aligned with the phase busbar located below, thereby realizing the positioning of two different types of phase connecting pins.
