Abstract
Description
Technical Field
[0001] This invention relates to the field of insulator processing technology, and in particular to a positioning and crimping fixture for composite insulators. Background Technology
[0002] In the field of power transmission and distribution, composite insulators play a crucial role as key equipment. They can not only effectively isolate high voltage electricity, prevent current leakage, and ensure the safe and stable operation of the power system, but also demonstrate good adaptability in various complex environments due to their excellent electrical performance, mechanical performance, and weather resistance. They are widely used in power facilities such as transmission lines and substations.
[0003] In the traditional composite insulator crimping installation process, due to the irregular shape and fragile texture of the insulator components, and the lack of effective positioning and fixing devices, they are prone to displacement or shaking during crimping. Therefore, crimping tools often cannot achieve uniform pressure on the insulator components, resulting in uneven pressure on different parts of the insulator components. Some areas may be over-compressed due to excessive pressure, resulting in deformation, cracking, and other damage, while other areas may be under-compressed due to insufficient pressure, resulting in gaps or looseness at the connection. This uneven crimping effect will seriously affect the electrical and mechanical properties of the insulator, reduce its safety and stability in actual operation, and may even cause power failures, posing a serious threat to the normal operation of the power system.

[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. This invention uses an air pump to inflate the air collecting plate, and uses air pressure to simultaneously pressurize and extrude the pressure rods in multiple sleeves, applying uniform pressure to the insulator workpiece. At the same time, the sliding plate inside the sleeve cooperates with the limiting spring to automatically adjust the size of the opening at the top of the sleeve when the air pressure is unbalanced, balancing the air pressure inside each sleeve and ensuring that the pressure applied by each pressure rod is uniform. This avoids damage to the insulator due to excessive local stress caused by uneven pressure, significantly improving the crimping quality and the service life of the insulator.
[0017] 2. This invention achieves omnidirectional stable positioning of the insulator by setting a first clamping plate and a second clamping plate at the top and bottom of the insulator processing part, and using a limiting plate to clamp the clamping plate assembly. This design can effectively prevent the insulator from shifting or shaking during the crimping process, ensure the accurate crimping position, improve the accuracy and reliability of the crimping installation, and ensure the connection strength and sealing between the insulator and the mounting shaft.
[0018] 3. The present invention uses a pressure-reducing component set at the top of the gas collecting plate to absorb and buffer pressure impact during the crimping process through a viscoelastic damper. This effectively reduces the instantaneous impact force on the equipment itself and the insulator components during crimping. This design not only protects the mechanical structure of the crimping fixture and extends the service life of the equipment, but also reduces the risk of damage to the internal structure of the insulator due to excessive impact force, further improving the safety and stability of the crimping process.
[0019] 4. The first and second clamping plates in the clamping plate assembly of the present invention achieve spacing adjustment through adjusting rods, which can flexibly adapt to insulator processing parts of different sizes and shapes. At the same time, the honeycomb plate installed inside the first clamping plate enhances the strength and stability of the clamping plate, and the protective pad further protects the surface of the insulator from damage. This makes the tooling have good versatility and adaptability, which can meet the crimping requirements of composite insulators of different specifications, and reduce production costs and equipment replacement frequency.

[0029] 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.
[0030] Please see Figure 1-8 The present invention provides a composite insulator positioning and crimping fixture, including a base 1 and an insulator processing component 2. The insulator processing component 2 is disposed at the top of the base 1. A processing frame 3 is fixedly installed at the top of the base 1. A crimping mechanism 4 with a screw 42 is disposed in the middle of the processing frame 3. The crimping mechanism 4 includes a screw 42 rotatably mounted on the surface of the processing frame 3 for pressing and moving a pressure component 45.
[0031] The screw 42 can move the pressure assembly 45, which can press down the insulator part 2 to achieve the crimping installation of the insulator part 2.
[0032] In the technical solution of this application embodiment, the pressurizing component 45 includes an air collecting plate 452 disposed on the surface of the screw 42. A cover plate 451 is sealed and installed on the top of the air collecting plate 452. An air pump 48 is installed on the top of the processing frame 3. An air outlet pipe 46 is installed between the output end of the air pump 48 and the air collecting plate 452. A plurality of sleeves 457 are installed at the bottom end of the air collecting plate 452. A pressure rod 458 is slidably installed inside the sleeve 457. A sliding plate 453 is slidably installed on the air collecting plate 452 near the inner bottom wall of the sleeve 457. A limit spring 454 is fixedly installed between the sliding plate 453 and the inner wall of the groove of the air collecting plate 452. An elastic rope 455 is fixedly installed between the sliding plate 453 and the pressure rod 458.
[0033] During the pressing of the insulator component 2 via the air collecting plate 452, the air pressure inside the air collecting plate 452 increases as the air pump 48 is activated to pressurize the air collecting plate 452. This increases the pressure, pushing the pressure rod 458 to slide within the sleeve 457. Multiple pressure rods 458 apply pressure to the insulator component 2. As the pressure rods 458 move, they drive the sliding plate 453 via the elastic rope 455, thus sealing the air inlet at the top of the sleeve 457. When the air pressure inside the multiple sleeves 457 is unbalanced, the pressure rods 458 move the sliding plate 453 by different distances, sealing the opening at the top of the sleeve 457. This regulates the air pressure inside the multiple sleeves 457, ensuring pressure balance and allowing the insulator component 2 to be pressed smoothly. This reduces pressure loss during pressing and ensures stable installation and use.
[0034] In some embodiments, two motors 41 are fixedly mounted on the surface of the processing frame 3, and a screw 42 is rotatably mounted on the top of the base 1. The output shaft of the motor 41 is fixedly connected to the screw 42. A threaded sleeve 43 is threadedly mounted on the outer surface of the screw 42, and a fixing rod 44 is fixedly mounted on the surface of the threaded sleeve 43. An air collecting plate 452 is fixedly mounted on the free end of the fixing rod 44.
[0035] In this process, by starting the motor 41, the motor 41 drives the screw 42 to rotate, the screw 42 drives the threaded sleeve 43 to move, the threaded sleeve 43 drives the fixed rod 44 to move, and the fixed rod 44 drives the pressure assembly 45 to move downward. The pressure assembly 45 presses down on the insulator part 2, thereby pressing the insulator part 2 into place through the air collecting plate 452. In this way, the motor 41 drives the screw 42 to rotate, precisely controlling the moving distance and direction of the threaded sleeve 43, thereby precisely controlling the pressure position of the pressure assembly 45 and ensuring the accuracy of the pressing process.
[0036] In some embodiments, a tension spring 456 for resetting the pressure rod 458 is provided at one end inside the sleeve 457, and an anti-friction pad is installed at the end of the pressure rod 458 near the insulator component 2.
[0037] The pressure rod 458 is equipped with a tension spring 456 at one end inside the sleeve 457. When the pressure rod 458 extends out of the sleeve 457 under air pressure and applies pressure to the insulator workpiece 2, the tension spring 456 will generate tension, causing the pressure rod 458 to tend to retract into the sleeve 457, thus achieving the reset of the pressure rod 458. An anti-friction pad is installed at the end of the pressure rod 458 near the insulator workpiece 2. The anti-friction pad can effectively reduce the friction between the pressure rod 458 and the insulator workpiece 2, avoid damage to the surface of the insulator workpiece 2 due to friction, and ensure the quality of the insulator workpiece 2.
[0038] In some embodiments, the top end of the gas collecting plate 452 is provided with a pressure relief assembly 47 with a viscoelastic damper 473, a pressure plate 471 is rotatably mounted on the surface of the threaded sleeve 43, a fixing plate 472 is fixedly mounted on the top end of the gas collecting plate 452, and the viscoelastic damper 473 is installed between the pressure plate 471 and the fixing plate 472.
[0039] During the crimping process, when the pressure rod 458 applies pressure to the insulator component 2, an impact force may be generated. After being subjected to pressure, the pressure plate 471 moves towards the fixed plate 472. The viscoelastic damper 473 absorbs and buffers the impact force through its own viscoelastic properties, protecting the insulator component 2 and other parts of the crimping fixture, reducing damage caused by excessive impact force, and at the same time, by buffering the impact force, the crimping process is made more stable, improving the crimping quality and ensuring that the connection between the insulator component 2 and the mounting shaft is firm and reliable.
[0040] In some embodiments, the processing frame 3 is provided with a fixing mechanism 5 with a limiting plate 55 inside. Two sliding rods 51 are fixedly installed inside the processing frame 3. Sliding sleeves 52 are slidably installed on the outer surface of the sliding rods 51. Long plates 53 are fixedly installed on the surfaces of the two sliding sleeves 52 that are close to each other. Support members 54 are fixedly installed on the surface of the long plates 53. The limiting plate 55 is fixedly installed on the free end of the support member 54, and the insulator processing part 2 is disposed between the two limiting plates 55.
[0041] The insulator component 2 is positioned between two limiting plates 55. When it is necessary to fix the insulator component 2, the position of the sliding sleeve 52 on the sliding rod 51 is moved, which drives the long plate 53, the support 54 and the limiting plate 55 to move. The cooperation between the sliding rod 51 and the sliding sleeve 52 can flexibly adjust the position of the limiting plate 55 to adapt to insulator components 2 of different sizes, improve the versatility of the tooling, and thus achieve the clamping and fixing of the insulator component 2.
[0042] In some embodiments, a clamping plate assembly 57 is provided inside the limiting plate 55 near the insulator processing part 2, and the two clamping plate assemblies 57 form a circle, with the insulator processing part 2 disposed inside the clamping plate assembly 57.
[0043] An adjusting rod 59 is provided between the first clamping plate 573 and the second clamping plate 58. By adjusting the length of the adjusting rod 59, the distance between the first clamping plate 573 and the second clamping plate 58 can be changed to accommodate insulator parts 2 of different heights. A buffer pad 56 is provided on the surface of the limiting plate 55 near the first clamping plate 573. The buffer pad 56 can play a buffering role during clamping and reduce the impact on the first clamping plate 573.
[0044] In some embodiments, the clamping plate assembly 57 includes a first clamping plate 573 installed on the inner top wall of the limiting plate 55, a second clamping plate 58 installed on the inner bottom wall of the limiting plate 55, and an insulator processing component 2 disposed between the first clamping plate 573 and the second clamping plate 58. An adjusting rod 59 for adjusting the spacing is disposed between the first clamping plate 573 and the second clamping plate 58, and a buffer pad 56 is disposed on the surface of the limiting plate 55 near the first clamping plate 573.
[0045] An adjusting rod 59 is provided between the first clamping plate 573 and the second clamping plate 58. By adjusting the length of the adjusting rod 59, the distance between the first clamping plate 573 and the second clamping plate 58 can be changed to accommodate insulator parts 2 of different heights. A buffer pad 56 is provided on the surface of the limiting plate 55 near the first clamping plate 573. The buffer pad 56 can play a buffering role during clamping and reduce the impact on the first clamping plate 573.
[0046] In some embodiments, a circular plate 571 is installed at the top of the first clamping plate 573, a honeycomb plate 572 is fixedly installed inside the first clamping plate 573, a protective pad 574 is installed on the surface of the first clamping plate 573 near the insulator component 2, and grooves and insert plates 575 are respectively opened on the surfaces of the two symmetrically installed first clamping plates 573 that are close to each other.
[0047] The first clamping plate 573 has a honeycomb plate 572 fixedly installed inside. The honeycomb plate 572 has high strength and light weight, which can enhance the structural strength of the first clamping plate 573. A protective pad 574 is installed on the surface of the first clamping plate 573 near the insulator workpiece 2. The protective pad 574 can prevent the first clamping plate 573 from directly contacting the insulator workpiece 2 and avoid scratching the insulator workpiece 2. The surfaces of the two symmetrically installed first clamping plates 573 that are close to each other are respectively provided with grooves and insert plates 575. When clamping the insulator workpiece 2, the matching structure of the grooves and insert plates 575 makes the connection between the two first clamping plates 573 tighter, improves the clamping stability, and ensures the smooth progress of the crimping process.
[0048] In some embodiments, a protrusion 576 is fixedly installed at the bottom end of the first clamping plate 573, and the protrusion 576 fills the space between the first clamping plate 573 and the insulator component 2.
[0049] The first clamping plate 573 has a protrusion 576 fixedly installed at its bottom end. When clamping the insulator workpiece 2, the protrusion 576 fills the space between the first clamping plate 573 and the insulator workpiece 2. The protrusion 576 can be designed according to the shape and size of the insulator workpiece 2 to better fit it. The protrusion 576 increases the friction between the first clamping plate 573 and the insulator workpiece 2, improves the clamping stability, and prevents the insulator workpiece 2 from sliding during the crimping process. At the same time, the protrusion 576 can better adapt to the shape of the insulator workpiece 2, making the first clamping plate 573 and the insulator workpiece 2 fit more tightly, reducing gaps and improving the crimping quality.
[0050] In some embodiments, a plurality of electric push rods 6 are fixedly installed on the top of the base 1, and a push plate 7 for limiting the installation shaft of the insulator processing part 2 is fixedly installed on the output shaft of the electric push rod 6, and the cross section of the push plate 7 is arc-shaped.
[0051] During the crimping installation of the insulator, the insulator needs to be crimped onto the mounting shaft of the insulator. By controlling the extension and retraction of the electric push rod 6, the push plate 7 limits the mounting shaft of the insulator processing part 2, ensuring that the mounting shaft remains stable during the crimping process. By stabilizing the position of the mounting shaft, the offset of the mounting shaft during the crimping process is avoided, the crimping accuracy is improved, and the installation quality of the insulator is ensured.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be covered within the scope of protection of this invention.
