Abstract
Description
Technical Field
[0001] This utility model relates to the field of compensator processing technology, specifically to a flange drilling device for compensator processing. Background Technology
[0002] Expansion joints, also commonly called compensators or expansion joints, consist of a bellows (an elastic element) as their main working component, along with accessories such as end pipes, supports, flanges, and conduits. Expansion joints are flexible structures installed on container shells or pipelines to compensate for additional stress caused by temperature differences and mechanical vibrations. They utilize the effective expansion and contraction deformation of their main working component, the bellows, to absorb dimensional changes in pipelines, conduits, and containers caused by thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements. They can also be used for noise reduction and vibration damping, and in heating systems. To prevent pipeline deformation or damage due to thermal expansion or temperature stress when heating pipelines heat up, compensators are installed on the pipelines to compensate for thermal expansion, thereby reducing stress on the pipe walls and the forces acting on valves or support structures. During the manufacturing of compensators, multiple holes for mounting bolts need to be drilled in the flanges of the compensator, thus requiring a flange drilling device for compensator manufacturing.
[0003] Existing drilling devices for flanges typically involve fixing the compensator using a clamping mechanism, rotating the compensator, and then drilling holes in the flange one by one using a drill bit. Precise flange rotation is required during this drilling process. Uneven hole distribution is crucial for successful installation; uneven drilling can negatively impact subsequent product installation. Furthermore, existing flange drilling devices for compensator processing suffer from drift in the compensator's center position during fixing and adjustment. Asynchronous lateral or opposing movements of the two clamping components can alter the compensator's position during rotation and drilling, causing a shift in the distance between the drilled holes and the flange's sides. This overall displacement of the drilled holes reduces drilling quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flange drilling device for compensator processing. It solves the problem that when the compensator is fixed and adjusted, the asynchronous left-right or opposite movement of the two clamping components may cause the center position of the compensator to change. As a result, when the compensator is rotated for drilling, the length of the drilling position from the two sides of the flange will change, leading to an overall offset of the drilling position and reducing the drilling quality.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] See Figure 1-7 This utility model provides a technical solution: a flange drilling device for compensator processing, the structure of which includes a base 1, a bracket 2 fixedly connected to the top of the base 1, a drilling mechanism 3 provided on the surface of the bracket 2, a mounting plate 4 fixedly connected to one side of the top of the base 1, a first driving member 5 fixedly connected to the bottom of the mounting plate 4, a first driving gear 6 fixedly connected to the output end of the first driving member 5, a rotating ring 7 provided on the top of the base 1, a toothed groove 8 opened on the outer surface of the rotating ring 7, the first driving gear 6 meshing with the toothed groove 8, a synchronous adjustment mechanism 9 provided inside the rotating ring 7, a compensator body 10 provided on the top side of the synchronous adjustment mechanism 9, a ball bearing 11 embedded in the bottom of the rotating ring 7, and the top of the base 1... The compensator body 10 is provided with an annular groove 12, and the ball bearing 11 is rolled and connected inside the annular groove 12. The compensator body 10 is fixed by the synchronous adjustment mechanism 9. Then, the position of the drilling mechanism 3 is adjusted according to the diameter of the compensator body 10 and the drilling position. After adjustment, the drilling mechanism 3 is used to drill holes on the surface of the compensator body 10. After each hole is drilled, the first driving component 5 is activated to drive the first driving gear 6 to rotate. The first driving gear 6 drives the rotating ring 7 to rotate through the tooth groove 8, thereby adjusting the drilling position of the compensator body 10 until all the required holes are drilled on the flange of the compensator body 10. Then, the compensator body 10 with holes drilled is removed from the synchronous adjustment mechanism 9.
[0030] The synchronous adjustment mechanism 9 includes a slide rail 91. The number of slide rails 91 is set to be multiple. One end of each slide rail 91 is centrally symmetrically and uniformly fixedly connected to the inner wall of the rotating ring 7. The other ends of the multiple slide rails 91 are fixedly connected together, and the multiple slide rails 91 are interconnected.
[0031] Among them, a connecting plate 92 is fixedly connected to multiple slide rails 91, a second driving member 93 is fixedly connected to the surface of the connecting plate 92, a second driving gear 94 is fixedly connected to the output end of the second driving member 93, and the second driving gear 94 and the rotating ring 7 are arranged in concentric circles.
[0032] A support block 95 is fixedly connected to one side of the slide rail 91. A slider 96 is slidably connected inside the slide rail 91. A fixing block 97 is fixedly connected to the top of the slider 96. A threaded rod 98 is rotatably connected inside the slide rail 91. One end of the threaded rod 98 passes through the support block 95 and is fixedly connected to a driven gear 99. The driven gear 99 is meshed with a second drive gear 94. Multiple fixing blocks 97 are placed simultaneously inside the compensator body 10, and the positions of the fixing blocks 97 are synchronized according to the inner diameter of the compensator body 10. Adjustment is performed so that the fixing block 97 can press against the compensator body 10. During adjustment, the second drive member 93 is activated to drive the second drive gear 94 to work. The second drive gear 94 drives the threaded rod 98 to rotate through the driven gear 99. Due to the restriction of the slide rail 91, the rotation of the threaded rod 98 causes the slider 96 to slide inside the slide rail 91, and multiple sliders 96 slide synchronously. The sliding of the slider 96 can drive the fixing block 97 to move, so that the fixing block 97 can slide to the inner wall of the compensator body 10 and press against it.
[0033] The slider 96 is threadedly connected to the threaded rod 98, and the threaded rod 98 is slidably connected to the support block 95.
[0034] The drilling mechanism 3 includes a third driving component 31, which is fixedly installed on the back of the bracket 2. The output end of the third driving component 31 is fixedly connected to a lead screw 32. One end of the lead screw 32 passes through the bracket 2 and is rotatably connected to the inner surface of the bracket 2. A moving block 33 is threadedly connected to the surface of the lead screw 32.
[0035] Among them, rollers 34 are fixedly connected to both sides of the movable block 33, and a groove 35 is opened on the inner surface of the bracket 2, and the rollers 34 are rotatably connected to the inside of the groove 35.
[0036] Hydraulic rods 36 are fixedly connected to both sides of the bottom of the movable block 33. The bottom ends of the two hydraulic rods 36 are fixedly connected to a motor 37. The output end of the motor 37 is fixedly connected to a drill bit 38. The third drive unit 31 is started to drive the lead screw 32 to rotate. Due to the restriction of the slide groove 35, the movable block 33 moves left and right. At the same time, the roller 34 slides inside the slide groove 35 until the bottom of the drill bit 38 is on the same vertical plane as the drilling position. When drilling, the hydraulic rods 36 and the motor 37 are started. The hydraulic rods 36 drive the motor 37 to move downward. The motor 37 drives the drill bit 38 to rotate, so the drill bit 38 continuously moves downward and drills the compensator body 10 until the drilling is completed.
[0037] When drilling holes in the flange of the compensator body 10 during operation, the compensator body 10 is first fixed by the synchronous adjustment mechanism 9. Then, the position of the drilling mechanism 3 is adjusted according to the diameter of the compensator body 10 and the drilling position. After adjustment, the drilling mechanism 3 is used to drill holes in the surface of the compensator body 10. After each hole is drilled, the first drive component 5 is activated to drive the first drive gear 6 to rotate. The first drive gear 6 drives the rotating ring 7 to rotate through the tooth groove 8, thereby adjusting the drilling position of the compensator body 10 until all the required holes are drilled on the flange of the compensator body 10. Then, the compensator body 10 with holes drilled is removed from the synchronous adjustment mechanism 9.
[0038] When using the synchronous adjustment mechanism 9 to fix the compensator body 10 to be drilled, firstly, multiple fixing blocks 97 are placed simultaneously inside the compensator body 10. Then, the positions of the fixing blocks 97 are adjusted synchronously according to the inner diameter of the compensator body 10, so that the fixing blocks 97 can press against the compensator body 10. During adjustment, the second drive component 93 is activated to drive the second drive gear 94 to work. The second drive gear 94 drives the threaded rod 98 to rotate through the driven gear 99. Due to the limitation of the slide rail 91, the rotation of the threaded rod 98 drives the slider 96 to move along the slide rail 91. The internal sliding mechanism 1 has multiple sliders 96 sliding synchronously. The sliding of sliders 96 can drive the fixed block 97 to move, so that the fixed block 97 can slide to the inner wall of the compensator body 10 and press against it. The center position between multiple sliders 96 does not change, thus ensuring that the center position of the compensator body 10 does not change. Therefore, when adjusting and clamping the compensator body 10, the center position will not change, ensuring that the distance from the two sides does not change when the compensator body 10 rotates to drill a hole, thus ensuring the uniformity of drilling.
[0039] Before drilling, the position of the drill bit 38 is adjusted according to the diameter of the center of the drilling trajectory. During adjustment, the third drive unit 31 is activated to drive the lead screw 32 to rotate. Due to the restriction of the slide groove 35, the moving block 33 moves left and right, while the roller 34 slides inside the slide groove 35 until the bottom of the drill bit 38 is on the same vertical plane as the drilling position. During drilling, the hydraulic rod 36 and the motor 37 are activated. The hydraulic rod 36 drives the motor 37 to move downward, and the motor 37 drives the drill bit 38 to rotate. Thus, the drill bit 38 continuously moves downward and drills the compensator body 10 until the drilling is completed. Then, the hydraulic rod 36 drives the drill bit 38 upward and drives the rotating ring 7 to rotate through the first drive gear 6, causing the compensator body 10 to rotate. The next drilling position rotates to below the drill bit 38, and the same drilling mechanism 3 drills at this position. This process is repeated until all the holes in the compensator body 10 are drilled.
