Description

Technical Field

[0001] This utility model belongs to the technical field of bolt broken wire removal devices, and particularly relates to a large bolt broken wire removal device. Background Technology

[0002] A large bolt breakage removal device is a tool or equipment used to remove broken threads from large bolts. When bolts on the flange of a high-pressure pump are under high temperature, high pressure and high preload, they become difficult to remove during maintenance, and the threads often get stuck. To facilitate the replacement or repair of bolts, a device is needed to treat them.

[0003] For example, Chinese patent document (CN111438663B) discloses a bolt breakage and wire removal device, which includes a pair of fixed seats. Neodymium magnet adsorption seats are fixedly installed at the bottom of the fixed seats on both sides. The housing has three coaxial cylindrical holes, an air bladder groove, and an oil reservoir. A bushing is fixedly inserted into the inner ring of the bearing. A traction rope is fixedly connected to the shaft of the rotating gear. The end of the compression air bladder away from the traction rope is connected to an air hole on the housing through a one-way air inlet valve. An air inlet is provided between the air bladder groove and the oil reservoir. An oil outlet is provided at the bottom of the oil reservoir. The bushing has an internal opening... The device includes a positioning groove in which a drill bit or a wire-retrieving head is movably inserted. This invention positions the drill bit and wire-retrieving head to ensure the stability and accuracy of the drill bit during drilling. Simultaneously, a loosening agent is injected along the hole wall, flowing around the broken bolt to loosen it. This simplifies the wire-retrieving process and improves efficiency. However, this device can only retrieve smaller screws, and it is difficult to remove harder bolts. Furthermore, it only allows for unilateral positioning, which may affect the uniformity of drilling. Therefore, improvements are needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-3 This utility model provides a technical solution: a large bolt wire removal device, including a clamping fixture 1, two fixing components 4 are provided on one side of the top of the clamping fixture 1, a magnetic drill 5 is provided below the fixing components 4, a connecting seat 6 is provided on the top of the magnetic drill 5, a driving component is provided inside the connecting seat 6, an adjusting rod 7 is provided on one side of the driving component, and a cooling component 8 is provided on the outer periphery of the adjusting rod 7.

[0032] The fixing component 4 includes a mounting box 401. One side of the mounting box 401 is fixedly connected to the outer wall of the clamping fixture 1, and a central through hole is provided at the junction of the clamping fixture 1 and the mounting box 401. The mounting box 401 has an inner cavity, and a rotating shaft 402 is provided on the top side of the inner cavity. A gear 403 is fixedly connected to the rotating shaft 402, and a ring gear 405 is meshed with the bottom of the gear 403. Multiple protrusions 406 are arranged in a circumferential array at equal angles inside the ring gear 405. A roller 407 is provided on the other side of the protrusions 406, and a horizontal plate 408 is fixedly connected to the other side of the roller 407. A fixing block 409 is fixedly connected to the other side of the horizontal plate 408. The rotating shaft 402 is rotatably connected inside the mounting box 401, and the end of the rotating shaft 402 away from the gear 403 extends to the outside of the mounting box 401 and is fixedly connected to the rotating shaft 402. The cross-section of the protrusion 406 is fan-shaped. The fixed block 409 extends into the central through hole on the side away from the horizontal plate 408, and the fixed block 409 is slidably connected inside the mounting box 401. A spring 410 is sleeved on the outer periphery of the fixed block 409. The two sides of the spring 410 are fixedly connected to the horizontal plate 408 and the inner wall of the mounting box 401, respectively. The output shaft of the drive assembly is connected to the conversion joint 2 on the side away from the adjusting rod 7. A hollow drill 3 is provided on the other side of the conversion joint 2.

[0033] Detailed Implementation: When a large bolt on the high-pressure pump body flange breaks during use, the protruding part of the bolt is cut off with an external cutting machine, and the surface is ground smooth. Then, the center position of the bolt is located and marked with a trowel. The center through hole inside the clamping jig 1 is aligned with the bolts on both sides of the broken part, and the bolts on both sides are inserted into the center through hole. When the outer wall of the bolt contacts the inner wall of the mounting box 401, the hand crank 404 is manually operated to drive the rotating shaft 402 and gear 403 to rotate. Utilizing the linkage effect between gear 403 and ring gear 405, power is transmitted to ring gear 405, causing ring gear 405 to drive the protrusion 406 to move. This causes the protrusion 406 to press against roller 407, horizontal plate 408, fixing block 409, and spring 410, causing the fixing block 409 to move towards the bolt and fix the outer surface of the bolt. This allows the clamping jig 1 to be quickly fixed to the high-pressure pump body flange. This improves the portability of the device during use. The magnetic drill 5 is then attached to the clamping fixture 1 and a center hole is drilled to mark the outer circle of the hollow drill 3 for easy alignment. After drilling, the magnetic drill bit is removed, and the hollow drill 3 is installed onto the magnetic drill 5 via the adapter 2. The hollow drill 3 then unclogs the broken threads of the large bolt. The magnetic drill 5 is then disassembled, and a special tool is used to remove the threads, ensuring the threads on the high-pressure pump flange are restored to their usable state. The size of the hollow drill 3 can be selected and adjusted according to actual needs. The adapter 2 solves the connection between the large hollow drill 3 and the magnetic drill 5, expanding the device's application range. Furthermore, the device avoids the risk of damage to the device body due to alignment deviations during drilling by using a centering alignment method. The clamping fixture 1 allows the installation and alignment of the magnetic drill 5 without a working surface, effectively improving the device's performance.

[0034] Cooling assembly 8 includes a mounting plate 801, which is fixedly connected to the outer periphery of an adjusting rod 7. The adjusting rod 7 is threaded into the inside of a connecting seat 6. A handle is fixedly connected to the adjusting rod 7 away from the outside of the connecting seat 6. A liquid bladder 802 is fixedly connected to one side of the mounting plate 801 opposite to the connecting seat 6. A connecting plate 803 is fixedly connected to the other side of the liquid bladder 802. A rotating seat 804 is rotatably sealed on the other side of the connecting plate 803 via a bearing. The other side of the rotating seat 804 is fixedly connected to the outer wall of the connecting seat 6. A cavity is formed inside the rotating seat 804. One side of the cavity is connected to the liquid bladder 802, and the top of the cavity is connected to the infusion tube 805. The other end of the infusion tube 805 is connected to the infusion frame 806. The bottom of the infusion frame 806 is fixedly connected to the top of the clamping fixture 1. Multiple nozzles are connected to the bottom of the infusion frame 806. Two guide tubes 807 are symmetrically arranged outside the liquid bladder 802. One end of the guide tube 807 is fixedly connected to the outer wall of the connecting plate 803. A guide post 808 is slidably connected inside the guide tube 807. The end of the guide post 808 away from the guide post 808 is fixedly connected to the outer wall of the mounting plate 801.

[0035] Detailed implementation: The position of the hollow drill 3 is adjusted by adjusting rod 7. During this process, mounting plate 801 will squeeze liquid bladder 802, and the liquid inside liquid bladder 802 will be transported to the inside of infusion frame 806 through infusion pipe 805. Then, it will be sprayed onto the surface of hollow drill 3 or magnetic drill bit through multiple nozzles to assist in cooling the surface and prevent it from affecting its service life and performance, thereby effectively improving the overall performance of the device.

[0036] Working Principle: When a large bolt on the high-pressure pump body flange breaks during use, the protruding part of the bolt is cut off with an external cutting machine, and the surface is ground smooth. The center position of the bolt is then located and marked with a saw. The center through-hole inside the clamping jig 1 is aligned with the bolts on both sides of the broken section, and the bolts on both sides are inserted into the center through-hole. When the outer wall of the jig contacts the inner wall of the mounting box 401, the hand crank 404 is manually operated to rotate the shaft 402 and gear 403. Utilizing the linkage effect between gear 403 and ring gear 405, power is transmitted to the ring gear 405, causing it to move the protrusion 406. This protrusion then presses against the roller 407, horizontal plate 408, fixing block 409, and spring 410, causing the fixing block 409 to move towards the bolt, thus fixing the outer surface of the bolt. This quickly fixes the clamping jig 1 onto the high-pressure pump body flange. Next, the magnetic drill 5 is attached to the clamping fixture 1 and a center hole is drilled to mark the outer circle of the hollow drill 3 for easy alignment. After drilling, the magnetic drill bit is removed, and then the hollow drill 3 is installed onto the magnetic drill 5 through the adapter 2, so that the hollow drill 3 can break through the broken threads of the large bolt. After that, the magnetic drill 5 is disassembled, and the threads on the high-pressure pump body flange are removed using a special tool to ensure that the threads are restored to their usable state. The size of the hollow drill 3 can be selected and adjusted according to actual needs. The adapter 2 solves the connection between the large hollow drill 3 and the magnetic drill 5, expanding the application range of the device. The position of the hollow drill 3 is adjusted by the adjusting rod 7. During this process, the mounting plate 801 will squeeze the liquid bladder 802, and the liquid inside the liquid bladder 802 will be transported to the inside of the infusion frame 806 through the infusion tube 805. Then, it will be sprayed onto the surface of the hollow drill 3 or the magnetic drill bit through multiple nozzles to assist in cooling the surface. It is convenient to use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
