[0006] The adaptive placement module includes two base plates and two placement platforms, with the two placement platforms fixedly connected to the upper sides of the two base plates respectively.

[0007] The welding auxiliary module includes two auxiliary seats and two rotating seats.

The two rotating seats are located on opposite sides of the two auxiliary seats respectively.

[0008] The system is equipped with an assembly frame, a front plate, a distribution plate, a tail frame, a movable seat, an adaptive placement module, and a welding auxiliary module. The adaptive placement module is used to arrange the insulators to be welded.

The movable platform is designed to meet the insulator placement requirements during welding, ensuring that the insulators can fully fit in the welding position and guaranteeing the welding operation.

[0011] In a preferred embodiment, two symmetrical displacement hydraulic cylinders are fixedly connected to the side of the assembly frame away from the tailstock, and the telescopic ends of the two displacement hydraulic cylinders are fixedly connected to the outer baffle on the same side.

[0014] By incorporating a welding auxiliary module, which uses two movable auxiliary seats in conjunction with a rotating seat to press and hold the two insulators to be welded, the two insulators are brought into contact, ensuring the welding effect. At the same time, during the welding operation, the rotating seat can drive the two insulators to rotate synchronously, achieving complete welding at the contact position and improving the overall smoothness of the welding process. The contact block is made of rubber, which can improve the clamping effect while avoiding over-clamping that could damage the insulators.

[0015] In a preferred embodiment, an electric slide rail is provided between the auxiliary frame and the tail frame. A movable frame is movably connected to the electric slide rail, and the tail frame has two symmetrical slide grooves.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The high-voltage power transmission and transformation insulator welding fixture disclosed in this invention is mainly used in scenarios where current welding equipment has poor adaptability and low welding efficiency.

[0029] Reference Figures 1-7A welding fixture for high-voltage power transmission and transformation insulators includes an assembly frame 1, a front plate 2 and two separate plates 3 on the assembly frame 1, and a tail frame 4 is bolted to one side of the assembly frame 1 near the two separate plates 3. The front plate 2 has two symmetrical sliding grooves, and a movable seat 5 is slidably connected inside the two sliding grooves. An adaptive placement module 6 is provided on each of the two movable seats 5. The assembly frame 1 is bolted to two symmetrical auxiliary frames 7, which are symmetrically distributed on the outside of the two separate plates 3. A welding auxiliary module 8 is provided on the two auxiliary frames 7.

[0030] The adaptive placement module 6 includes two base plates 601 and two placement platforms 602, with the two placement platforms 602 located on the upper side of the two base plates 601 and connected by bolts.

[0031] The welding auxiliary module 8 includes two auxiliary seats 801 and two rotating seats 802. The two auxiliary seats 801 are symmetrically distributed, and the two rotating seats 802 are rotatably connected to the two auxiliary seats 801 through bearings. The two rotating seats 802 are located on opposite sides of the two auxiliary seats 801.

[0032] Specifically, the adaptive placement module 6 is adjusted according to the specifications of the two insulators to be welded. Then, the two insulators to be welded are placed on the two adaptive placement modules 6 respectively. The starting device moves the two insulators to the welding position (welding auxiliary module 8). The welding auxiliary module 8 clamps and fixes the two insulators. Then, the two insulators are welded with the assistance of the welding auxiliary module 8.

[0033] In specific application scenarios, the device uses an adaptive placement module 6 to place and arrange the insulators to be welded. The adaptive placement module 6 can adaptively adjust according to the actual specifications of the insulators to be welded, thereby meeting the welding requirements of insulators of different specifications. The welding auxiliary module 8 is used to assist welding, which can realize the complete welding operation of the insulator while ensuring the stability of the insulator position during welding, thus improving the smoothness of the welding process.

[0034] Reference Figure 3 , Figure 4 and Figure 5In a preferred embodiment, the adaptive placement module 6 further includes two L-shaped frames 603, which are bolted together on the underside of two base plates 601. A sliding groove is provided on the movable seat 5, and the two L-shaped frames 603 are slidably connected within the groove. A station plate 604 is bolted to the underside of each base plate 601, and a sliding groove is provided on each of the two partition plates 3. The two station plates 604 are slidably connected within the grooves of the two partition plates 3. Each L-shaped frame 603 has threaded holes with opposite thread directions. A reverse motor 605 is bolted to one side of the movable seat 5, and a lead screw 608 is connected to the output end of the reverse motor 605 via a coupling. One end of the screw 608 passes through the threaded holes of the two L-shaped brackets 603 and is rotatably connected to the inner wall of one side of the movable seat 5 via bearings. The screw 608 is rotatably connected to the threaded holes of the two L-shaped brackets 603 via the inner wall threads. An outer baffle 606 is bolted to the side of the movable seat 5 away from the distribution plate 3. Rectangular grooves are provided on both base plates 601. Multiple movable sliding rods 609 are bolted between the inner walls of the two sides of the rectangular grooves. A movable platform 607 is provided inside the rectangular groove. Multiple through holes are provided on the movable platform 607. The multiple movable sliding rods 609 are slidably connected inside the multiple through holes. Return springs 610 are bolted to both sides of the movable platform 607. The other end of the return spring 610 is bolted to the inner wall of the adjacent movable platform 607.

[0035] Specifically, the adaptive placement module 6 is adjusted according to the specifications of the insulators to be welded:

[0036] Two reverse motors 605 are started simultaneously to drive the lead screw 608 to rotate. The two L-shaped frames 603 on the movable seat 5 move closer or further apart from each other. The positions of the two base plates 601 on the movable seat 5 are changed to meet the placement requirements of the insulator to be welded. Then, a pushing or pulling force is applied to the outer baffle 606 to move the movable seat 5 on the assembly frame 1. The positions of the two movable seats 5 are adjusted so that the two movable seats 5 meet the welding point alignment requirements of the insulator.

[0037] Upon reaching the welding position, the welding auxiliary module 8 will run as follows:

[0038] The welding auxiliary module 8 applies pressure to the two insulators to be welded from the outside. The two insulators to be welded move closer to each other until they are completely in contact. During this process, the two insulators to be welded are brought closer together by force, the movable platform 607 is shifted by force, and the return spring 610 undergoes elastic deformation.

[0039] In specific application scenarios, the adaptive placement module 6 is suitable for the arrangement and placement of insulators to be welded and the insulator placement stage of the welding process. That is, the adaptive placement module 6 can adjust the position of the placement platform 602 according to the actual specifications of the insulators to be welded, so that the placement platform 602 can meet the placement requirements of insulators of different specifications and improve the applicability of the device. The movable platform 607 is movable and can meet the insulator placement requirements during welding, so that the insulators can achieve full fit requirements when in the welding position, ensuring the welding operation of the insulators.

[0040] Reference Figure 4 In a preferred embodiment, two symmetrical displacement hydraulic cylinders 9 are bolted to the side of the assembly frame 1 away from the tailstock 4, and the telescopic ends of the two displacement hydraulic cylinders 9 are bolted to the outer baffle 606 on the same side.

[0041] Specifically, when adjusting the position of the movable seat 5, two shifting hydraulic cylinders 9 are activated to extend and retract synchronously. After the outer baffle 606 is subjected to force, it drives the two movable seats 5 to move closer to each other or further away. By using the shifting hydraulic cylinders 9 to adjust the position of the two movable seats 5, it can adapt to the welding position requirements of insulators of different specifications and further improve the applicability of the device.

[0042] Reference Figure 5 and Figure 6 In a preferred embodiment, the welding auxiliary module 8 further includes an auxiliary motor 804. Slide grooves are provided on the upper sides of both attachments 7. Two auxiliary seats 801 are slidably connected within the slide grooves of the two attachments 7. Self-adjusting hydraulic cylinders 805 are bolted to both attachments 7. The extension and retraction ends of the two self-adjusting hydraulic cylinders 805 are bolted to the attachments 7 on the same side. An auxiliary motor 804 is bolted to one attachment 7. The output shaft of the auxiliary motor 804 is connected to a short shaft via a coupling. The other end of the short shaft passes through the attachment 7 and is bolted to a rotating seat 802. Contact blocks 803, made of rubber, are bolted to the opposite sides of both rotating seats 802.

[0043] Specifically, when the two insulators to be welded are moved to the welding position (the two insulators move from the placement platform 602 to the position of the movable platform 607, and the two insulators are between the two auxiliary frames 7), the two self-adjusting hydraulic cylinders 805 are activated to extend and retract synchronously, and the two auxiliary seats 801 move closer to each other until the contact blocks 803 on the two rotating seats 802 contact and press with the outer side of the two insulators, so that the two insulators move closer together until they are completely in contact;

[0044] During the welding operation, the auxiliary motor 804 is started to drive the rotating seat 802 on the auxiliary seat 801 to rotate, and the two insulators and the auxiliary seat 801 maintain a uniform and synchronous rotation state.

[0045] In specific application scenarios, the welding auxiliary module 8 is suitable for clamping and fixing two insulators during welding operations and for assisting in welding. Specifically, the welding auxiliary module 8 uses two movable auxiliary seats 801 in conjunction with the rotating seat 802 to press and fix the two insulators to be welded, achieving the fit between the two insulators and ensuring the welding effect. At the same time, during the welding operation, the rotating seat 802 can drive the two fitted insulators to rotate synchronously, achieving complete welding at the fit position of the two insulators and improving the overall smoothness of the welding process. The contact block 803 is made of rubber, which can improve the clamping effect while avoiding over-clamping that could damage the insulators.

[0046] Reference Figure 2 , Figure 4 and Figure 5 In a preferred embodiment, an electric slide rail 10 is provided between the auxiliary frame 7 and the tail frame 4. A movable frame 11 is slidably connected to the electric slide rail 10. The tail frame 4 has two symmetrical sliding grooves. The side of each of the two movable seats 5 away from the outer baffle 606 is bolted to a limiting slide rod 12. The other ends of the two limiting slide rods 12 are slidably connected in the two sliding grooves of the tail frame 4, respectively. The outside of each of the two limiting slide rods 12 is slidably connected to a pusher frame 13. The two pusher frames 13 are symmetrically distributed on both sides of the movable frame 11. The side of each of the two pusher frames 13 near the tail frame 4 is bolted to a push plate 14. Both pusher frames 13 have round holes. The movable frame 11 is bolted to a synchronous push rod 15. The synchronous push rod 15 is slidably connected in the round holes of the two pusher frames 13, respectively.

[0047] Specifically, after the two insulators to be welded are placed, the electric slide rail 10 is activated to move the moving frame 11 to the tail frame 4. The two push frames 13 move forward synchronously under the action of the synchronous push rod 15, pushing the two insulators to be welded forward synchronously until they reach the position of the movable platform 607. The limiting slide rod 12 is fixedly connected to the movable seat 5. When the movable seat 5 is adjusted, the limiting slide rod 12 moves synchronously, so the push frame 13 moves along with the limiting slide rod 12 (the push frame 13 slides outside the synchronous push rod 15). After the welding operation is completed, the moving frame 11 will be reset under the drive of the electric slide rail 10, waiting for the next welding operation. By using the moving frame 11 to drive the push frame 13, the synchronous movement of the two insulators on the placement platform 602 is realized.

[0048] Reference Figure 5 and Figure 7In a preferred embodiment, a welding box 16 is provided on the outer side of the tailstock 4. A tilting shaft 17 is rotatably connected to one inner wall of the welding box 16 via a bearing. The other end of the tilting shaft 17 passes through the other side wall of the welding box 16 and is bolted to a driving gear 19. Two symmetrical stop bars 18 are bolted to the outside of the tilting shaft 17. An adjusting motor 20 is bolted to one inner wall of the welding box 16. The output shaft of the adjusting motor 20 passes through the wall of the welding box 16 and is bolted to a drive gear 21. The drive gear 21 and the driving gear 19 mesh with each other through tooth grooves. A welding table 22 is slidably connected between the two inner walls of the welding box 16, and a welding torch 23 is provided on the welding table 22.

[0049] Specifically, the adjusting motor 20 is adjusted according to the specifications of the insulator to be welded. The adjusting motor 20 drives the drive gear 21 to mesh with the traction gear 19, and the flipping shaft 17 flips to drive the stop rod 18 to deflect, so as to realize the limit requirements of insulators of different specifications. After the welding auxiliary module 8 clamps and fixes the two insulators to be welded, the positions of the welding table 22 and the welding gun 23 are adjusted according to the welding point position of the insulator to be welded, and then the welding operation is carried out.

[0050] Working principle: During use, the adaptive placement module 6 is adjusted according to the specifications of the two insulators to be welded (two reverse motors 605 are started simultaneously to drive the lead screw 608 to rotate, the two L-shaped frames 603 on the movable seat 5 move closer or further away from each other, the positions of the two base plates 601 on the movable seat 5 are changed to meet the placement requirements of the insulators to be welded, and then two shifting hydraulic cylinders 9 are started to extend and retract synchronously. After the outer baffle 606 is subjected to force, it drives the two movable seats 5 to move closer or further away from each other. The movable seats 5 move on the assembly frame 1 so that the two movable seats 5 meet the welding point alignment requirements of the insulators).

[0051] Place the two insulators to be welded on the two adaptive placement modules 6 respectively. Start the device to move the two insulators to the welding position (welding auxiliary module 8). That is, start the electric slide rail 10 to drive the moving frame 11 to the tail frame 4 position. The two push frames 13 move forward synchronously under the action of the synchronous push rod 15, pushing the two insulators to be welded forward synchronously until they reach the position of the live platform 607.

[0052] Subsequently, the welding auxiliary module 8 clamps and fixes the two insulators (two self-adjusting hydraulic cylinders 805 are activated to extend and retract synchronously, and the two auxiliary seats 801 move closer to each other until the contact blocks 803 on the two rotating seats 802 contact and press with the outer side of the two insulators, so that the two insulators move closer together until they are completely attached). Then, with the assistance of the welding auxiliary module 8, the two insulators are welded (the auxiliary motor 804 is activated to drive the rotating seat 802 on one of the auxiliary seats 801 to rotate, and the two insulators and the auxiliary seat 801 maintain a uniform synchronous rotation state. During the process, the welding torch 23 completely welds the contact position of the two insulators).

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
