Description

Technical Field

[0001] The utility model belongs to the technical field of reactor production and manufacturing, and particularly relates to an adjustable multi-screw press-fitting device. Background Art

[0002] A reactor, also called an inductor, generates a magnetic field within a certain space it occupies when a conductor is energized, so all current-carrying electrical conductors have inductance in the general sense. A delta-shaped reactor is a type of reactor, whose three-phase core legs are arranged in a delta shape, so as to ensure the compactness of the delta-shaped reactor, reduce noise, and prolong the service life of the reactor.

[0003] In the manufacturing process of the reactor, a reactor core pressing device is required to ensure effective and reliable press-fitting of the entire reactor core, so as to reduce the influence and displacement of the coil caused by vibration generated during the operation of the reactor. However, the traditional pressing beam method for pressing has limited pressing force on the coil position, and the long-term pressing state is prone to wear through the insulating layer, resulting in communication between the iron core and the clamping member, causing potential safety hazards. Contents of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable multi-screw press-fitting device, which has the advantages of ensuring that the reactor core leg is in a pressed state, and the up-and-down tension of the connecting screw can ensure the strength and stability of each component of the iron core.

[0005] The above technical purpose of the utility model is achieved through the following technical solution: an adjustable multi-screw press-fitting device, comprising two lower clamping plates, two upper clamping plates and connecting plates, the two upper clamping plates and the two lower clamping plates are integrally I-shaped, an upper iron yoke is sandwiched between the two upper clamping plates, a lower iron yoke is sandwiched between the two lower clamping plates, the two upper clamping plates are connected through the connecting plate, the two lower clamping plates are also connected through the connecting plate, a reactor core leg is sandwiched between the upper iron yoke and the lower iron yoke, a connecting screw is connected between the upper clamping plate and the lower clamping plate located on one side, the connecting plate is integrally connected with a pressing block, and the connecting plate and the pressing block are integrally T-shaped.

[0006] By adopting the above technical solution: the two lower clamping plates are connected through the connecting plate, and the two upper clamping plates are also connected through the connecting plate, while the upper clamping plate and the lower clamping plate on one side are connected through the connecting screw, so that the lower clamping plate, the upper clamping plate and the connecting plate can form a stable whole, which frames the upper iron yoke and the lower iron yoke, and ensures that the reactor core leg between the upper iron yoke and the lower iron yoke can be clamped tightly.

[0007] Meanwhile, the pressing block on the connecting plate can contact the upper iron yoke or the lower iron yoke.

[0008] The present invention is further configured such that both the upper clamping plate and the lower clamping plate have an outer cavity and an inner cavity, the two sides of the upper yoke are placed on the inner cavities of the two upper clamping plates, and the two sides of the lower yoke are placed on the inner cavity of the lower clamping plate.

[0009] The above technical solution allows for easy support of the upper and lower yokes by the inner cavity before the two upper clamping plates and the two lower clamping plates are connected by a connecting plate. This facilitates the clamping and fixing of the upper and lower yokes.

[0010] The present invention is further configured such that one end of the connecting screw is located in the inner cavity of the upper clamping plate, and the other end is located in the inner cavity of the lower clamping plate.

[0011] The above technical solution is adopted: the connecting screw is used to connect and tighten the upper and lower clamping plates on one side.

[0012] The present invention is further provided that both ends of the connecting screw are threaded with locking nuts.

[0013] The above technical solution is adopted: the inner wall of the inner cavity is provided with a through hole through which the connecting screw passes, and the locking nut connected by the connecting screw can be pressed on the inner wall of the inner cavity so that the upper clamping plate and the lower clamping plate can be connected together.

[0015] By adopting the above technical solution, the spring can provide sufficient clamping force when the connecting screw connects the upper and lower clamping plates, and has good buffering and shock absorption capabilities, which can better absorb impact and dissipate energy.

[0016] The present invention is further configured such that the lower clamping plate and the connecting plate are connected by bolts, and the upper clamping plate and the connecting plate are also connected by bolts.

[0017] The above technical solution is adopted: the two lower clamping plates are connected to the connecting plate by bolts, so that the lower clamping plates and the connecting plate are connected as a whole; the two upper clamping plates are connected to the connecting plate by bolts, so that the upper clamping plates and the connecting plate are connected as a whole.

[0018] The present invention is further configured such that a fastening screw passing through the reactor core column is connected between the upper yoke and the lower yoke.

[0019] The above technical solution is adopted: the fastening screw is used to further connect the upper yoke and the lower yoke to ensure that the upper yoke and the lower yoke can press the reactor core column tightly.

[0020] The present invention is further configured such that anti-loosening washers are fitted at both ends of the fastening screw, and fastening nuts that press on the anti-loosening washers are threaded to both ends of the fastening screw.

[0021] The above technical solution is adopted: the two ends of the fastening screw pass through the upper yoke and the lower yoke respectively, and the two ends of the fastening screw are threaded to fastening nuts, so that the upper yoke and the lower yoke are connected together.

[0023] 2. By incorporating a connecting screw, a locking nut, a connecting washer, and a spring, this utility model provides excellent buffering and shock absorption capabilities when the connecting screw connects to the upper and lower clamping plates, thus better absorbing impact and dissipating energy.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1: refer to Figure 1 , Figure 3An adjustable multi-screw press-fitting device includes two lower clamping plates 1, two upper clamping plates 2, and a connecting plate 3. The two upper clamping plates 2 and the lower clamping plates 1 are all in the shape of an I-beam. An upper yoke 4 is clamped between the two upper clamping plates 2, and a lower yoke 5 is clamped between the two lower clamping plates 1. The two upper clamping plates 2 are connected by the connecting plate 3, and the two lower clamping plates 1 are also connected by the connecting plate 3. A reactor core column 7 is clamped between the upper yoke 4 and the lower yoke 5. A connecting screw 8 is connected between the upper clamping plate 2 and the lower clamping plate 1 on one side.

[0028] The two lower clamping plates 1 are connected by a connecting plate 3, and the two upper clamping plates 2 are also connected by a connecting plate 3. The upper clamping plate 2 on one side is connected to the lower clamping plate 1 by a connecting screw 8, so that the lower clamping plate 1, the upper clamping plate 2, and the connecting plate 3 can form a stable whole. The upper iron yoke 4 and the lower iron yoke 5 of the frame column ensure that the reactor core column 7 between the upper iron yoke 4 and the lower iron yoke 5 can be clamped.

[0029] refer to Figure 1 , Figure 4 Both the upper clamping plate 2 and the lower clamping plate 1 have an outer cavity 9 and an inner cavity 10. The two sides of the upper yoke 4 are placed on the inner cavities 10 of the two upper clamping plates 2, and the two sides of the lower yoke 5 are placed on the inner cavity 10 of the lower clamping plate 1.

[0030] Before the two upper clamping plates 2 and the two lower clamping plates 1 are connected by the connecting plate 3, the inner cavity 10 can easily support the upper yoke 4 and the lower yoke 5. After that, the two upper clamping plates 2 and the two lower clamping plates 1 are connected by the connecting plate 3, which can easily clamp and fix the upper yoke 4 and the lower yoke 5.

[0031] refer to Figure 1 , Figure 3 One end of the connecting screw 8 is located inside the inner cavity 10 of the upper clamping plate 2, and the other end is located inside the inner cavity 10 of the lower clamping plate 1.

[0032] The connecting screw 8 is used to connect and tighten the upper clamping plate 2 and the lower clamping plate 1 on one side.

[0033] refer to Figure 2 , Figure 3 Both ends of the connecting screw 8 are threaded with locking nuts 13.

[0034] The inner wall of the inner cavity 10 has a through hole through which the connecting screw 8 passes, and the locking nut 13 threaded to the connecting screw 8 can be pressed against the inner wall of the inner cavity 10 so that the upper clamping plate 2 and the lower clamping plate 1 can be connected together.

[0035] refer to Figure 2 , Figure 3The inner bottom wall of the inner cavity 10 of the upper clamping plate 2 and the inner top wall of the lower clamping plate 1 are both connected to springs 11 sleeved on the connecting screw 8. A connecting washer 12 connected to the spring 11 is also sleeved on the connecting screw 8.

[0036] The spring 11 can provide sufficient clamping force when the connecting screw 8 connects the upper clamping plate 2 and the lower clamping plate 1, and has good buffering and shock absorption capabilities, which can better absorb impact and dissipate energy.

[0037] refer to Figure 1 , Figure 2 The lower clamping plate 1 and the connecting plate 3 are connected by bolts 17, and the upper clamping plate 2 and the connecting plate 3 are also connected by bolts 17.

[0038] The two lower clamping plates 1 are connected to the connecting plate 3 by bolts, so that the lower clamping plates 1 and the connecting plate 3 are connected as a whole. The two upper clamping plates 2 are connected to the connecting plate 3 by bolts, so that the upper clamping plates 2 and the connecting plate 3 are connected as a whole.

[0039] Brief description of the usage process: First, connect one lower clamping plate 1 to the connecting plate 3 with bolts 17. Then, connect one upper clamping plate 2 to the connecting plate 3 with bolts 17. Next, place the two sides of the upper yoke 4 on the inner cavity 10 of the two upper clamping plates 2. Then, place the two sides of the lower yoke 5 on the inner cavity 10 of the two lower clamping plates 1. Then, connect another upper clamping plate 2 to the connecting plate 3 with bolts 17 and another lower clamping plate 1 to the connecting plate 3 with bolts 17. This will clamp the upper yoke 4 and the lower yoke 5. Then, press the reactor core column 7 with the upper yoke 4 and the lower yoke 5. Finally, connect the upper clamping plate 2 and the lower clamping plate 1 with the connecting screw 8.

[0040] Example 2: Based on Example 1, and referring to Figure 1 , Figure 3 An adjustable multi-screw pressing device further includes a pressing block 6, and a connecting plate 3 is integrally connected to the pressing block 6, with the connecting plate 3 and the pressing block 6 forming an overall T-shape.

[0041] The pressure block 6 on the lower connecting plate 3 is used to abut against the lower yoke 5, and the pressure block 6 on the upper connecting plate 3 is used to abut against the upper yoke 4.

[0042] refer to Figure 1 , Figure 2 A fastening screw 15, which passes through the reactor core column 7, connects the upper yoke 4 and the lower yoke 5.

[0043] The fastening screw 15 is used to further connect the upper yoke 4 and the lower yoke 5 to ensure that the upper yoke 4 and the lower yoke 5 can press the reactor core column 7 tightly.

[0044] refer to Figure 1 , Figure 2 Both ends of the fastening screw 15 are fitted with anti-loosening washers 14, and both ends of the fastening screw 15 are threaded with fastening nuts 16 that press against the anti-loosening washers 14.

[0045] The two ends of the fastening screw 15 pass through the upper yoke 4 and the lower yoke 5 respectively, and the two ends of the fastening screw 15 are threaded to the fastening nut 16, so that the upper yoke 4 and the lower yoke 5 are connected together.

[0046] Brief description of the usage process: When the two upper clamping plates 2 clamp the upper yoke 4 and the two lower clamping plates 1 clamp the lower yoke 5, the pressure block 6 of the lower connecting plate 3 abuts against the lower yoke 5, and the pressure block 6 of the upper connecting plate 3 abuts against the upper yoke 4, so that the upper yoke 4 and the lower yoke 5 can exert force on the reactor core column 7.

[0047] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
