Description

Technical Field

[0001] This utility model relates to the field of bellows compensator technology, and more specifically, to a fixing fixture for processing and assembling bellows compensators. Background Technology

[0002] A bellows compensator, also commonly called an expansion joint or telescoping joint, consists of a bellows (an elastic element) that forms its main working body, along with accessories such as end pipes, supports, flanges, and guide pipes. It is mainly used in various pipelines to compensate for thermal displacement, mechanical deformation, and absorb various mechanical vibrations, thereby reducing pipeline deformation stress and extending pipeline service life.

[0003] During the production process of bellows compensators, tensile tests are required. However, the existing telescopic clamps used in the production and processing of bellows compensators only have clamping functions and do not have telescopic functions, which affects the production efficiency of bellows compensators.

[0004] A search revealed that Chinese patent CN214186833U discloses a telescopic clamp for the production and processing of bellows compensators. By controlling the threaded rod with a knob, the transmission nut moves to the left or right. The transmission nut then moves the first and second transmission rods to the left or right, thereby moving the clamping device to the left or right. This allows the clamping device to freely adjust its extension and retraction when clamping the bellows compensator, facilitating production work for the staff.

[0005] In actual use, the telescopic clamps used for manufacturing and processing the aforementioned bellows compensators only use two clamping rods to clamp the bellows compensators, lacking any limiting function for the bellows compensators. This can cause displacement due to external forces during processing, resulting in deviations in the bellows compensators and affecting assembly accuracy. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fixing fixture for processing and assembling bellows compensators, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fixing fixture for processing and assembling a bellows compensator includes a base, a worktable fixedly connected to the top of the base, a positioning component and a clamping mechanism provided on the outside of the worktable, and the clamping mechanism being installed on one side of the positioning component.

[0009] The positioning assembly includes multiple support plates, each with a telescopic spring fixedly connected to one side. A limit ring is fixedly connected to one end of each telescopic spring, and two first sliders are fixedly connected to the bottom of the limit ring. Multiple first sliding grooves are formed on the upper surface of the base, with the first sliders slidably connected to the inner sides of the first sliding grooves. Two rollers are rotatably connected inside the limit ring. A first electric push rod is fixedly connected to one side of the limit ring, with a fixed ring fixedly connected to the output end of the first electric push rod. The fixed ring is slidably connected to the inside of the limit ring, and a bellows compensator is provided between the multiple limit rings.

[0010] By adopting the above technical solution, the stability of the second electric push rod during the processing is enhanced, and the positioning deviation caused by human operation or equipment error is reduced.

[0011] As a further description of the above technical solution: the clamping mechanism includes a second electric push rod, which is installed inside the base. The output end of the second electric push rod is fixedly connected to a movable plate. Multiple first hinge supports are fixedly connected to the outside of the movable plate. A push rod is hinged to the inside of the first hinge supports. One end of the push rod is hinged to a second hinge support. A support ring is fixedly connected to one side of the second hinge support. Multiple guide rods are slidably connected inside the movable plate. The bottom end of the guide rod is fixedly connected to the upper surface of the worktable. A limit plate is fixedly connected to the top end of the guide rod. The bottom ends of the multiple support rings are all fixedly connected to second sliders. Multiple second slide rails are provided on the upper surface of the worktable. The second sliders are slidably connected to the inner sides of the second slide rails.

[0012] By adopting the above technical solution, the second electric push rod can be securely clamped and limited, thereby improving the overall accuracy.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up positioning components, compared with the existing technology, multiple rollers can assist the second electric push rod to move downward. The telescopic movement of multiple limit rings can adapt to the second electric push rod of different sizes. And multiple fixing rings can limit the movement on the outside of the second electric push rod, which can ensure the positional accuracy of the second electric push rod during processing and assembly, facilitate the increase of the stability of the second electric push rod during processing, help reduce processing errors caused by vibration or displacement, and improve product quality.

[0015] 2. By setting up a clamping mechanism, compared with the existing technology, multiple limiting rings can provide annular support and limit the second electric push rod on the inner side, and correspond to the support points of multiple fixing rings on the outer side of the second electric push rod, thereby stably limiting the second electric push rod, evenly dispersing the stress during the processing, and reducing the deformation or damage of the bellows caused by excessive local stress.

[0023] 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.

[0024] The embodiments disclosed in this application are as follows: Figure 1-5 The shown is a fixing fixture for processing and assembling a bellows compensator, including a base 1, a worktable 2 fixedly connected to the top of the base 1, a positioning component and a clamping mechanism provided on the outside of the worktable 2, and the clamping mechanism is installed on one side of the positioning component.

[0025] The positioning assembly includes multiple support plates 3, each with a telescopic spring 4 fixedly connected to one side. A limit ring 5 is fixedly connected to one end of each telescopic spring 4, and two first sliders 6 are fixedly connected to the bottom of the limit ring 5. Multiple first grooves 7 are formed on the upper surface of the base 1, and the first sliders 6 are slidably connected to the inner sides of the first grooves 7. Two rollers 8 are rotatably connected inside the limit ring 5. A first electric push rod 9 is fixedly connected to one side of the limit ring 5, and a fixing ring 10 is fixedly connected to the output end of the first electric push rod 9. The fixing ring 10 is slidably connected to the inside of the limit ring 5. Corrugated tubes are provided for compensation between the multiple limit rings 5. The device 11 utilizes the extension and retraction of multiple telescopic springs 4 to drive the limiting rings 5 ​​to adapt to the second electric push rods 12 of different sizes, so that the multiple limiting rings 5 ​​can be positioned on the outside of the second electric push rods 12. At the same time, when the second electric push rods 12 are pressed down, multiple rollers 8 can assist the second electric push rods 12 in moving. Then, the first electric push rod 9 is activated to push the fixed rings 10 to move, so that the multiple fixed rings 10 can be limited on the outside of the second electric push rods 12. This helps to increase the stability of the second electric push rods 12 during the processing and helps to reduce processing errors caused by vibration or displacement.

[0026] Reference Figure 3 and 6 As shown, the clamping mechanism includes a second electric push rod 12, which is installed inside the base 1. A movable disk 13 is fixedly connected to the output end of the second electric push rod 12. Multiple first hinge supports 14 are fixedly connected to the outer side of the movable disk 13. A push rod 15 is hinged to the inner side of each first hinge support 14. A second hinge support 16 is hinged to one end of each push rod 15. A support ring 17 is fixedly connected to one side of the second hinge support 16. Multiple guide rods 18 are slidably connected inside the movable disk 13. The bottom end of each guide rod 18 is fixedly connected to the upper surface of the worktable 2. A limit disk 19 is fixedly connected to the top end of each guide rod 18. Second sliders 20 are fixedly connected to the bottom ends of the multiple support rings 17. Multiple second slide rails 21 are provided on the upper surface of the worktable 2. The second sliders 20 and the second... The slide rail 21 is slidably connected to the inside. The movable plate 13 is moved by the second electric push rod 12, which in turn drives the multiple first hinge supports 14 to move. The push rod 15 is hinged to the inner sides of the first hinge supports 14 and the second hinge supports 16 at both ends, so that when the movable plate 13 moves, the support ring 17 can be moved by the push rod 15 to support and fix it inside the second electric push rod 12. At the same time, the support point of the support ring 17 inside the second electric push rod 12 corresponds to the support point of the multiple fixed rings 10 outside the second electric push rod 12. Thus, the multiple support rings 17 and the fixed rings 10 can cooperate to clamp and limit the second electric push rod 12, which can stably limit the second electric push rod 12 and improve the processing stability.

[0027] Working principle of this utility model: This utility model designs a fixing fixture for the processing and assembly of bellows compensators. The specific structure is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation between various structures, when the second electric push rod 12 needs to be assembled, the bottom end of the second electric push rod 12 is first placed between multiple limiting rings 5, and the second electric push rod 12 is pressed down. Utilizing the extension and retraction of multiple telescopic springs 4, and with the first slider 6 slidably connected to the inner side of the first slide groove 7, the multiple limiting rings 5 ​​can extend and retract according to the size of the second electric push rod 12. Multiple rollers 8 are rotatably connected to the inside of the limiting rings 5, so that the second electric push rod 12 can be assisted to move downward when pressed down. At the same time, the multiple limiting rings 5 ​​can be positioned on the outside of the second electric push rod 12. Then, the first electric push rod 9 is activated, and the first electric push rod 9 can push the fixing ring 10 to fit against the outside of the second electric push rod 12, thereby further positioning the second electric push rod 12.

[0028] Then, the second electric push rod 12 is activated, which pushes the movable plate 13 upward. Multiple guide rods 18 provide guidance for the movement of the movable plate 13, allowing the movable plate 13 to drive multiple first hinge supports 14 to move. The two ends of the push rod 15 are respectively hinged to the inner sides of the first hinge supports 14 and the second hinge supports 16, allowing the movable plate 13 to push the support ring 17 to move outward through the push rod 15. The second slider 20 is slidably connected to the inner side of the second slide rail 21, which provides guidance for the movement of the support ring 17. Multiple support rings 17 can support and limit the second electric push rod 12. At the same time, the support points of multiple support rings 17 on the inner side of the second electric push rod 12 correspond to the support points of multiple fixed rings 10 on the outer side of the second electric push rod 12, so as to better limit and fix the second electric push rod 12, thereby facilitating the subsequent processing and assembly of the second electric push rod 12.
