Description

Technical Field

[0001] This utility model relates to the technical field of coupling locking, specifically a circumferential fastening device for machining radial couplings. Background Technology

[0002] Couplings are key components in mechanical transmissions, responsible for connecting two shafts or a shaft to a rotating component, transmitting motion and power, and providing overload protection. Their core function is to connect two shafts or a shaft to a rotating component and ensure synchronous rotation during motion and power transmission.

[0003] When assembling existing couplings, the mounting holes on the two coupling parts are generally aligned. External auxiliary tools are used to tighten the bolts one by one. Multiple threads are passed through the mounting holes and tightened in sequence. During the tightening process, it is necessary to ensure that the bolts are aligned with the mounting holes. If the tightening force of the threads is different, the axes of the two coupling parts may not be collinear, resulting in uneven force on the coupling during operation, which will produce periodic impacts. Utility Model Content

[0004] The purpose of this invention is to provide a circumferential fastening device for machining radial couplings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circumferential fastening device for machining radial couplings is used to fix two radial couplings, wherein multiple grooves are formed on the radial couplings.

[0007] The circumferential fastening device includes a first ring hoop and a second ring hoop. One end of the second ring hoop is hinged to the first ring hoop, and the other end is provided with a plurality of locking elements that can lock the first ring hoop.

[0008] The first ring and the second ring are respectively provided with limiting protrusions that can be inserted into the groove.

[0009] The circumferential fastening device for the radial coupling as described above: pressure plates are symmetrically arranged on the first ring clamp and the second ring clamp, and multiple buffer mechanisms are arranged between the two pressure plates.

[0010] The circumferential fastening device for the radial coupling as described above: arc-shaped grooves are formed on the first ring hoop and the second ring hoop respectively, and an arc-shaped block that is slidably connected to the arc-shaped groove is provided on the pressure plate.

[0011] The circumferential fastening device for the radial coupling as described above: the buffer mechanism includes a plug-in cylinder fixedly installed on one of the pressure plates, a plug-in rod slidably disposed at the end of the plug-in cylinder away from the pressure plate, and the end of the plug-in rod away from the plug-in cylinder being fixed to the other pressure plate;

[0012] It also includes a first spring, which is disposed inside the plug tube. One end of the first spring abuts against the plug rod, and the other end abuts against the inner end of the plug tube.

[0013] The circumferential fastening device of the radial coupling as described above: a plurality of insertion slots are formed on the second ring, and one end of the insertion slot is threadedly connected to a threaded rod capable of pressing the locking member.

[0014] The circumferential fastening device for the radial coupling as described above: the locking member includes a connecting rod, one end of which is slidably disposed in the insertion groove, and the other end is movably disposed with a ball that can be inserted into the locking hole formed by the first ring hoop;

[0015] It also includes a pressure plate that is slidably disposed in the insertion slot, the pressure plate being rotatably connected to the threaded rod, and a second spring being disposed in the insertion slot, one end of the second spring abutting against the pressure plate and the other end abutting against the connecting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When two radial couplings are connected, the two ends of the first ring are aligned with the radial couplings respectively. Rotating the second ring and combining it with the first ring forms a circular structure. After the locking element initially locks the first ring, the locking element is controlled to further lock the second ring, so as to achieve a tight connection between the first and second rings. The axes of the first and second rings coincide. During installation, it is not necessary to align the mounting holes on the couplings one by one and tighten the bolts. This ensures a stable connection between the two radial couplings while keeping the coupling axes always collinear, which simplifies the installation process and saves manpower and time costs.

[0026] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0027] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0028] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0029] Please see Figures 1-7 In this embodiment of the utility model, a circumferential fastening device for machining radial couplings is used to fix two radial couplings, wherein multiple grooves are formed on the radial couplings;

[0030] The circumferential fastening device includes a first ring hoop 1 and a second ring hoop 2. One end of the second ring hoop 2 is hinged to the first ring hoop 1, and the other end is provided with a plurality of locking elements that can lock the first ring hoop 1.

[0031] The first ring 1 and the second ring 2 are respectively provided with limiting protrusions 3 that can be inserted into the groove.

[0032] In this embodiment, when the two radial couplings are connected, the two ends of the first ring clamp 1 are aligned with the radial couplings respectively. The second ring clamp 2 is rotated to combine with the first ring clamp 1 to form a ring structure. After the locking member initially locks the first ring clamp 1, the locking member is controlled to further lock the second ring clamp 2 to achieve a tight connection between the first ring clamp 1 and the second ring clamp 2. The axes of the first ring clamp 1 and the second ring clamp 2 coincide. During installation, it is not necessary to align the mounting holes on the couplings one by one and tighten the bolts. This ensures that the two radial couplings are stably connected while keeping the coupling axes always collinear, which simplifies the installation process and saves manpower and time costs.

[0033] It should be noted that the limiting protrusions 3 on the first ring clamp 1 and the second ring clamp 2 are inserted into the groove, which can effectively prevent the radial coupling from rotating relative to each other during installation or operation, thereby improving the stability and reliability of the connection.

[0034] Preferably, baffles 4 are provided at both ends of the first ring clamp 1 and the second ring clamp 2, which can further limit the position of the coupling.

[0035] As a further embodiment of this invention, pressure plates 5 are symmetrically arranged on the first ring hoop 1 and the second ring hoop 2, and multiple buffer mechanisms are arranged between the two pressure plates 5.

[0036] Preferably, the first ring hoop 1 and the second ring hoop 2 are respectively formed with arc-shaped grooves, and the pressure plate 5 is provided with an arc-shaped block 501 that is slidably connected to the arc-shaped grooves.

[0037] Among them, the end of the pressure plate 5 away from the buffer mechanism has a pressing surface 502. When the two pressure plates 5 are inserted between the radial couplings, the pressing surface 502 is pressed by the couplings, and the pressure plate 5 is subjected to a force that moves toward the buffer mechanism. Under the restriction of the arc-shaped groove and the arc-shaped block 501, the pressure plate 5 moves relative to the couplings to make room for the couplings, so as to facilitate the installation of the first ring hoop 1 and the second ring hoop 2.

[0038] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The buffer mechanism includes a plug-in cylinder 7 fixedly installed on one of the pressure plates 5, a plug-in rod 6 slidably disposed at the end of the plug-in cylinder 7 away from the pressure plate 5, and the end of the plug-in rod 6 away from the plug-in cylinder 7 fixed to the other pressure plate 5;

[0039] It also includes a first spring 8, which is disposed inside the plug tube 7. One end of the first spring 8 abuts against the plug rod 6, and the other end abuts against the inner end of the plug tube 7.

[0040] In the initial state, the first spring 8 is in a compressed state. At this time, the position of the pressure plate 5 is restricted by the arc-shaped groove. After the first ring clamp 1 and the second ring clamp 2 are aligned with the coupling, the pressure plate 5 squeezes the first spring 8 again. When the two radial couplings are subjected to vibration or impact, the deformation of the first spring 8 can absorb and release energy, avoid damage to the coupling, and not affect the stable connection between the first ring clamp 1 and the second ring clamp 2 and the coupling.

[0041] For further solutions to this utility model, please refer to [link / reference]. Figure 6 and Figure 7 The second ring 2 has a plurality of insertion slots, and one end of each insertion slot is threadedly connected to a threaded rod 9 capable of pressing against the locking member.

[0042] The locking component includes a connecting rod 11, one end of which is slidably disposed in the insertion groove, and the other end is movably disposed with a ball 1101 that can be inserted into the locking hole 101 formed by the first ring 1.

[0043] It also includes a pressure plate 10 that is slidably disposed in the insertion slot. The pressure plate 10 is rotatably connected to the threaded rod 9, and a second spring 12 is disposed in the insertion slot. One end of the second spring 12 abuts against the pressure plate 10, and the other end abuts against the connecting rod 11.

[0044] Specifically, after the second ring 2 rotates to initially engage with the first ring 1, the ball 1101 is inserted into the locking hole 101. At this time, the connection between the first ring 1 and the second ring 2 is unstable. By controlling the rotation of the threaded rod 9, the threaded rod 9 moves towards the insertion groove along its own axis while rotating. The pressure plate 10 is squeezed by the threaded rod 9 and moves towards the second spring 12 in the insertion groove. When the ball 1101 is further inserted into the locking hole 101, the connecting rod 11 is inserted into the locking hole 101. At this time, the outer wall of the connecting rod 11 abuts against the outer wall of the locking hole 101. The first ring 1 and the second ring 2 cannot easily separate, thereby achieving a stable connection between the first ring 1 and the second ring 2, and ensuring the fastening of the coupling by the ring structure formed by the first ring 1 and the second ring 2.
