[0002] Hydraulic pressure bolts are special fasteners used for high-pressure sealing connections, widely applied in fields such as petrochemicals, power, and aerospace where sealing and safety requirements are extremely high. These bolts achieve tightening through precisely controlled hydraulic pressure technology, ensuring the reliability and sealing of the connection under extreme operating conditions.

[0003] A search revealed Chinese patent CN213497000U, which discloses a bolt thread repair structure. This structure addresses the limitations of existing bolt repair structures, which cannot be adjusted according to the bolt's diameter and length. Furthermore, the lack of a guiding direction makes the bolt prone to damage, reducing the accuracy of bolt repair. However, hydraulic fastening bolts are mostly twelve-angle flange bolts. Using two screws to fix the bottom of the bolt can easily result in a fixed contact area that is essentially a line. During the bolt repair process, the bolt may rotate, leading to reduced repair efficiency. Utility Model Content

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-6 This utility model provides a hydraulic fastening bolt thread repair device, including a base 1, a rotating frame 2 rotatably connected to the top of the base 1, a slide 4 slidably connected to the outer circumference of the rotating frame 2, a die 19 for repairing the thread of the fastening bolt on the top of the slide 4, the die 19 being mounted on the slide 4 by a fixing component, a lower mounting hole 5 being opened on the top of the base 1, a mounting seat 3 being placed in the lower mounting hole 5, a placement hole 11 for placing the flange face of the fastening bolt being opened on the top of the mounting seat 3, a protrusion that fits into the flange face of the fastening bolt being opened on the inner circumference of the placement hole 11, the mounting seat 3 being used in sets, each set having multiple placement holes 11 of different specifications, wherein the diameter of the largest placement hole 11 is not greater than the diameter of the mounting seat 3;

[0026] In use, the corresponding mounting base 3 is equipped according to the model of the fastening bolt. The mounting base 3 is installed into the lower mounting hole 5, and then one end of the fastening bolt is inserted into the placement hole 11 to complete the installation and limiting of the fastening bolt. Then, the appropriate die 19 is selected according to the model of the fastening bolt, and the die 19 is installed on the slide 4. The slide 4 is slid down to make the die 19 contact the fastening bolt. Then, the slide 4 is rotated so that the die 19 repairs the threads of the fastening bolt. The placement hole 11 is provided with multiple diameters, which can be selected according to the needs. The fastening bolt is limited by the protrusion and the placement hole 11, so that the fastening bolt cannot be rotated, thereby completing the complete fixation of the fastening bolt. At the same time, the fastening bolt and the die 19 can be quickly aligned so that their midpoints are on the same center line, which improves the ease of use and fixing stability of the device.

[0027] In this utility model, the fixing component includes an upper mounting hole 17 opened on the top of the slide 4, a fixing bracket 18 placed in the upper mounting hole 17, a die 19 fixed in the fixing bracket 18 by bolts and keyway, and the bottom end of the die 19 extends beyond the bottom end of the slide 4. The top of the slide 4 is provided with a limiting component for fixing the fixing bracket 18.

[0028] The die 19 is placed in the mounting bracket 18 according to the keyway, and then the die 19 is fixed with bolts to make the die 19 and the mounting bracket 18 an integral unit. Then the mounting bracket 18 is placed in the upper mounting hole 17 and fixed with the limiting component, thereby completing the installation of the die 19. The upper mounting hole 17 has various specifications, which can install dies 19 of different specifications. The maximum diameter of the upper mounting hole 17 does not exceed the diameter of the mounting bracket 18. It can be selected according to the needs to improve the applicability of the device.

[0029] The limiting component includes multiple external threaded plates 15 welded to the top of the carriage 4, and the multiple external threaded plates 15 are combined to form a ring with a notch. The inner diameter of the ring is not less than the diameter of the upper mounting hole 17, and the outer circumference of the ring is threaded with a fixing screw 16.

[0030] After the mounting bracket 18 is installed on the slide 4, the fixing screw 16 is fitted over the ring and rotated to move the fixing screw 16 downward, so that the bottom of the fixing screw 16 contacts the mounting bracket 18, thereby limiting the mounting bracket 18 and preventing the mounting bracket 18 from moving out of the upper mounting hole 17, thus improving the stability of the device.

[0031] The slide 4 has multiple through holes at its bottom, and a mounting bracket 13 is fitted inside each hole. A scraper 14 is welded to the bottom of the mounting bracket 13. The top of the mounting bracket 13 is fixed to the slide 4 at an adjustable angle by a nut. The bottom end of the scraper 14 does not exceed the bottom end of the die 19, so as not to affect the repair of the fastening bolt by the die 19. After the fastening bolt thread is repaired, the die 19 is removed, and the scraper 14 is rotated to adjust the angle of the scraper 14 so that one end of the scraper 14 can enter the lower mounting hole 5. The slide 4 is rotated so that the scraper 14 scrapes off the debris that falls on the base 1, allowing the debris to enter the lower mounting hole 5 and cleaning the debris on the base 1, thus improving the cleaning effect of the device.

[0032] The bottom of the rotating frame 2 is rotatably connected to an L-shaped frame 12. When one end of the L-shaped frame 12 contacts the bottom of the slide 4, the L-shaped frame 12 limits the slide 4 so that it will not slip, which facilitates the placement of fastening bolts and improves the ease of use of the device.

[0033] The base 1 has a sliding hole 6 on one side, and a collection box 8 is slidably connected in the sliding hole 6. The top of the collection box 8 has a collection groove 9, and the diameter of the collection groove 9 is not less than the diameter of the lower mounting hole 5. The lower mounting hole 5 has a limit groove on one side that prevents the mounting seat 3 from rotating. This limit groove is used to guide the debris, so that the debris will not remain in the lower mounting hole 5. The debris that falls into the lower mounting hole 5 will fall directly into the collection groove 9 for collection, which facilitates the unified treatment of the debris.

[0034] One side of the base 1 is rotatably connected to a baffle 7, and one end of the baffle 7 is in contact with the collection box 8. The baffle 7 limits the collection box 8 so that the collection box 8 will not move out of the sliding hole 6.

[0035] The working principle of this utility model is as follows: A corresponding mounting base 3 is provided according to the type of fastening bolt. The mounting base 3 is installed into the lower mounting hole 5. Then, one end of the fastening bolt is inserted into the placement hole 11, thus completing the installation limit of the fastening bolt. A suitable die 19 is selected according to the type of fastening bolt. The die 19 is placed in the fixing bracket 18 according to the keyway. Then, the die 19 is fixed with bolts, making the die 19 and the fixing bracket 18 an integral unit. The fixing bracket 18 is then placed into the upper mounting hole 17. A fixing screw 16 is fitted over the ring. Rotating the fixing screw 16 moves it downwards, thereby allowing the bottom of the fixing screw 16 to move downwards. The die 19 is installed by contacting the fixing bracket 18 and limiting the fixing screw 16 against the fixing bracket 18. The slide 4 is slid down to make the die 19 contact the fastening bolt. Then the slide 4 is rotated so that the die 19 repairs the threads of the fastening bolt. The die 19 is provided with placement holes 11 of various diameters, which can be selected according to the needs. The fastening bolt is limited by the protrusion and the placement hole 11, so that the fastening bolt cannot be rotated, thus completing the complete fixation of the fastening bolt. At the same time, the fastening bolt and the die 19 can be quickly aligned so that their midpoints are on the same center line, which improves the ease of use and the stability of the device.
