[0002] At present, when assembling some components such as static contacts, bolt connection structures and pipe joint connection structures are involved. In order to ensure the centring of the static contact and the reliable connection of the threaded structure, the bolts of the static contact assembly body need to be diagonally and cyclically fastened, and a predetermined torque needs to be applied to the pipe joint connection structure.
[0003] In the prior art, when the bolts are diagonally and cyclically fastened, the static contact assembly body needs to be rotated to the corresponding position by manpower to diagonally and cyclically fasten the bolts. Since the static contact assembly body has a certain weight, it is difficult to diagonally and cyclically fasten the bolts. When the predetermined torque is applied to the pipe joint connection structure, one hand of the assembler needs to fix the static contact assembly body on the workbench, and the other hand needs to apply the torque. This is likely to cause the loss of the bottom torque, resulting in that the applied torque does not reach the predetermined torque, and affecting the assembly reliability. SUMMARY

[0020] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so as to be easily carried out by one of ordinary skill in the art. Also, portions irrelevant to the description of the exemplary embodiments are omitted in the accompanying drawings for the sake of clarity.
[0021] In the present disclosure, it should be understood that terms such as "include" or "have" are intended to indicate that there are features, numbers, steps, actions, components, parts or combinations thereof disclosed in the specification, and do not exclude the possibility that one or more other features, numbers, steps, actions, components, parts or combinations thereof exist or are added.
[0022] It should also be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0023] The assembly device provided by the embodiment is mainly used for assembling a specific component, which refers to any component containing a bolt connection structure and / or a pipe joint connection structure. For example, it can be a component containing a bolt connection structure, which needs to be diagonally and circularly fastened, or a component containing a pipe joint connection structure, which needs to be applied with a predetermined torque, or a component containing both the bolt connection structure and the pipe joint connection structure, which needs to be diagonally and circularly fastened and applied with a predetermined torque.
[0024] Figure 1 A structural schematic diagram of an assembly device of a component is shown. As shown in the figure, the assembly device comprises a rotating disc 1, a fixed disc 2, a limiting part 3 and a limiting part 4. Figure 1 As shown in the figure, the rotating disc 1 is provided with the limiting part 3 and the limiting part 4, the limiting part 3 is used to cooperate with the bottom part of the component assembly body to limit the bottom part of the component assembly body at a predetermined position of the rotating disc 1, which can prevent the relative movement between the rotating disc 1 and the component assembly body.
[0025] As shown in the figure, the rotating disc 1 is provided with the limiting part 3 and the limiting part 4, the limiting part 3 is used to cooperate with the bottom part of the component assembly body to limit the bottom part of the component assembly body at a predetermined position of the rotating disc 1, which can prevent the relative movement between the rotating disc 1 and the component assembly body. Figure 1
[0026] In one possible implementation, the limiting component 3 comprises at least two positioning pins which are inserted into positioning holes of the bottom end part of the component assembly, and the engagement between the positioning pins and the positioning holes can limit the bottom end part of the component assembly at a predetermined position of the rotating disc 1. For example, as shown in Figure 1 The rotating disc 1 is provided with two positioning pins, and of course, in other examples, the limiting component 3 can comprise three or more positioning pins, which are generally uniformly distributed on the rotating disc 1.
[0027] In another possible implementation, the limiting component 3 comprises at least three buckles which are engaged with the edges of the bottom end part of the component assembly to fix the bottom end part of the component assembly at a predetermined position of the rotating disc 1. Generally, the buckles are uniformly distributed on the rotating disc 1.
[0028] Of course, in other implementations, the limiting component 3 can also have other structures such as clamps and the like, as long as it can fix the bottom end part of the component assembly on the rotating disc 1, which is not limited herein.
[0029] In one possible implementation, the limiting component 3 is used to limit the bottom end part of the component assembly at a predetermined position of the rotating disc 1, so that the center of the bottom end part is located on the central axis of the rotating disc, so that the center of gravity of the component assembly can remain unchanged when the rotating disc rotates, which is more conducive to the diagonal cyclic tightening of the bolts.
[0030] Figure 2 A top view of a fixed disc provided by an embodiment of the present disclosure is shown. As shown in Figure 2 The fixed disc 2 is in the form of a ratchet wheel with a plurality of teeth, Figure 2 The fixed disc 2 has four teeth, and of course, in other implementations, the fixed disc 2 has five or six teeth, which is not limited herein. As shown in Figure 1 The fixed disc 2 is fixedly connected with the rotating disc 1, and the fixed disc 2 can continuously rotate in the first direction (i.e., counterclockwise) under the driving of the rotating disc 1 without being blocked by the limiting component 4. When the fixed disc 2 rotates in the second direction (i.e., clockwise) under the driving of the rotating disc 1, it will be blocked on the gear of the fixed disc 2 by the limiting component 4, thereby locking the rotation of the fixed disc 2 in the second direction.
[0031] When assembling the component, the bottom part of the component assembly can be matched with the limiting part 3 of the rotating disc 1 to limit the bottom part of the component assembly at a predetermined position of the rotating disc 1, and then the remaining parts can be assembled on the bottom part. During the assembly of the component, if diagonal cyclic tightening of the bolt is required, the rotating disc 1 can drive the fixed disc 2 and the component assembly to rotate in the first direction and hover at positions required for diagonal cyclic tightening in sequence, so that the assembler can tighten the bolt in the order required for diagonal cyclic tightening. If a predetermined torque needs to be applied to the threaded connection structure in the second direction, the rotating disc 1 can drive the fixed disc 2 and the component assembly to rotate in the second direction, and the limiting part 4 can be clamped on the gear of the fixed disc 2 to lock the rotation of the fixed disc 2 and the component assembly in the second direction, so that the assembler can apply a predetermined torque to the threaded connection structure in the second direction.
[0032] Here, the first direction and the second direction are opposite directions. When the first direction is the clockwise direction, the second direction is the counterclockwise direction. When the first direction is the counterclockwise direction, the second direction is the clockwise direction. Figure 1 For example, the first direction is the counterclockwise direction and the second direction is the clockwise direction. After the assembly of the component using the assembly section shown in FIG. 4, the threaded connection structure on the component needs to apply a predetermined torque in the clockwise direction. Figure 1
[0033] The assembly device for the component provided in the embodiment includes a rotating disc 1, a fixed disc 2, and a limiting part 3 and a limiting part 4 arranged on the rotating disc 1. When the bolt is diagonally cyclically tightened, the rotating disc 1 drives the fixed disc 2 and the component assembly to rotate in the first direction and hover at positions required for diagonal cyclic tightening in sequence, so that the assembler can tighten the bolt in sequence. In this way, the diagonal cyclic tightening of the bolt is realized by the rotation of the rotating disc 1, which saves manpower and makes the diagonal cyclic tightening of the bolt easy even if the component assembly has a certain weight. When a predetermined torque needs to be applied to the threaded connection structure, the rotating disc 1 drives the fixed disc 2 and the component assembly to rotate in the second direction, and the limiting part 4 is clamped on the gear of the fixed disc 2 to lock the rotation of the fixed disc 2 and the component assembly in the second direction, so that the assembler can apply a predetermined torque to the threaded connection structure in the second direction. The application of the torque is more convenient, the bottom torque loss can be avoided, the applied torque can reach the predetermined torque, and the assembly reliability is ensured.
[0034] In a possible implementation, the limiting component 3 is slidably connected with the rotating disc 1, and the limiting component 3 slides radially on the rotating disc 1, where radial refers to sliding towards the center of the rotating disc 1. When the limiting component 3 slides to a corresponding position, the limiting component 3 is locked on the rotating disc 1 by a locking component.
[0035] When the limiting component 3 includes at least two positioning pins, the at least two positioning pins can be slid to positions corresponding to positioning holes on the bottom end part of the component assembly according to the positions of the positioning holes, and the limiting component 3 is locked on the rotating disc 1 by a locking component, so that the positioning pins are inserted into the corresponding positioning holes to limit the bottom end part of the component assembly at a predetermined position of the rotating disc 1.
[0036] When the limiting component 3 includes at least three buckles, the bottom end part of the component assembly can be placed on the rotating disc 1 first, and then the at least three buckles are slid to positions corresponding to the edge positions of the bottom end part of the component assembly to be clamped, and then the limiting component 3 is locked on the rotating disc 1 by a locking component, so that the bottom end part of the component assembly is limited at a predetermined position of the rotating disc 1.
[0037] The embodiment can slidably connect the limiting component 3 with the rotating disc 1, and the limiting component 3 slides radially on the rotating disc 1, so that the bottom end parts of different component assemblies can be fixed on the rotating disc 1, and the assembly device is suitable for various component assemblies and has strong versatility.
[0038] In a possible implementation, the limiting component 3 is detachably connected with the rotating disc 1.
[0039] When the limiting component 3 includes at least two positioning pins, since the shapes and / or sizes of the positioning holes of the bottom end parts of different component assemblies can be different, the positioning pins can be detachably connected with the rotating disc 1, and for positioning holes of different shapes and / or sizes, positioning pins of corresponding shapes and / or sizes can be installed.
[0040] When the limiting component 3 includes at least three buckles, since the edge sizes and / or shapes of the bottom end parts of different component assemblies can be different, the buckles can be detachably connected with the rotating disc 1, and for bottom end parts of different edge shapes and / or sizes, buckles of corresponding shapes and / or sizes can be installed.
[0041] The embodiment can detachably connect the limiting component 3 with the rotating disc 1 to be suitable for fixing the bottom end parts of different component assemblies, so that the assembly device has better versatility.
[0042] In a possible implementation, the limiting component 4 comprises at least one sliding pin, such as Figure 1 As shown, the limiting component 4 comprises four sliding pins, and each tooth on the fixed disc 2 is provided with a sliding pin. Figure 3 A structural schematic diagram of a sliding pin provided by an embodiment of the present disclosure is shown in FIG. 4. Figure 3 As shown, the sliding pin comprises a fixed block 41, a blocking pin 42, a spring 43, and a bolt 44. The fixed block 41 is fixed on the rotating disc 1, and a slide channel in the radial direction of the rotating disc 1 is arranged in the fixed block 41. The blocking pin 42 is located in the slide channel. The spring 43 is wound on the bolt 44, one end of the spring 43 is connected to the fixed block 41, and the other end is connected to the blocking pin 42. The bolt 44 is fixedly connected with the blocking pin 42.
[0043] In this embodiment, in the case of the fixed disc 2, Figure 1 When the rotating disc 1 drives the fixed disc 2 to rotate in the first direction, i.e., the counterclockwise direction, with the rotation of the fixed disc 2, the blocking pin 42 is stopped by the teeth of the fixed disc 2 and slides outward, causing the spring 43 to be stretched. When a tooth of the fixed disc 2 rotates past the blocking pin 42, the blocking pin 42 slides inward to contact the next tooth of the fixed disc 2 under the action of the spring 43. In this way, the teeth on the fixed disc 2 can slide past the blocking pin 42 in turn without being blocked, and the rotating disc 1 drives the fixed disc 2 and the component assembly to continuously rotate in the counterclockwise direction. When the rotating disc 1 drives the fixed disc 2 to rotate in the second direction, i.e., the clockwise direction, with the rotation of the fixed disc 2, the blocking pin 42 will be stuck in the teeth of the fixed disc 2, locking the rotation of the fixed disc 2 in the clockwise direction.
[0044] Of course, in other embodiments, the gear direction of the fixed disc 2 can be reversed. At this time, the first direction is the clockwise direction, and the second direction is the counterclockwise direction.
[0045] In a possible implementation, the limiting component 4 comprises at least one pawl structure, and the pawl structure comprises a pawl, a pawl seat, and an elastic connecting piece. The pawl seat is fixed on the rotating disc 1. The pawl is installed on the pawl seat through the elastic connecting piece.
[0046] In this embodiment, when the rotating disk 1 drives the fixed disk 2 to rotate in the first direction, as the fixed disk 2 rotates, the pawl is pushed outward by the teeth of the fixed disk 2, causing the elastic connector to be stretched. When one tooth of the fixed disk 2 passes the stop pin 42, under the action of the elastic connector, the pawl rotates inward to contact the next tooth of the fixed disk 2. In this way, the teeth on the fixed disk 2 can slide past the pawl in sequence without being blocked, realizing that the rotating disk 1 drives the fixed disk 2 and the component assembly to rotate continuously in the first direction. When the rotating disk 1 drives the fixed disk 2 to rotate in the second direction, as the fixed disk 2 rotates, the pawl will lock the teeth of the fixed disk 2, preventing the fixed disk 2 from rotating in the second direction.
[0047] In one possible implementation, the fixed disk 2 and the rotating disk 1 are connected by a deep groove ball bearing and a thrust bearing.
[0048] In this embodiment, the deep groove ball bearing is a common type of bearing, characterized by simple structure, ease of use, low coefficient of friction, high limiting speed, high precision, and good interchangeability. It mainly bears radial loads and is used to ensure the coaxial rotation of the fixed disk 2 and the rotating disk 1. The thrust bearing is a bearing specifically designed to bear axial loads. Its main function is to allow rotational motion under axial force while minimizing friction. In this embodiment, the thrust bearing is mainly used to bear the weight of the component assembly.
[0049] In one possible implementation, the component includes a stationary contact structure of a high-voltage circuit breaker, which is a component comprising a bolted connection structure and a threaded connection structure.
[0050] Example, Figure 4 This illustration shows an assembly diagram of the stationary contact structure of a high-voltage circuit breaker according to an embodiment of the present disclosure, as shown below. Figure 4 As shown, the fixed disk 2 and the rotating disk 1 in the assembly device are connected by a deep groove ball bearing 5 and a thrust bearing 6. The limiting component 3 on the rotating disk 1 is a positioning pin, and the limiting component 4 on the rotating disk 1 is a sliding pin. Figure 4 The image shows the retaining block 41 and the stop pin 42 in the sliding pin. When assembling the stationary contact structure, the bottom part of the stationary contact assembly, i.e., Figure 4The positioning hole on the lower terminal block 71 in the middle is matched with the limiting component 3, i.e. the positioning pin of the rotating disc 1, the lower terminal block 71 of the static contact assembly is limited at the predetermined position of the rotating disc 1, then the static support 72, the static contact 73 and the static arc contact 74 can be assembled on the bottom end part in sequence, the bolt connection is needed between the lower terminal block 71 and the static support 72, the bolt connection is needed between the static support 72 and the static contact 73, the bolt connection structure is provided, at this time the diagonal circulation fastening of the bolt is needed, the rotating disc 1, the fixed disc 2 and the static contact assembly can be driven to rotate along the first direction and hover to the positions required by the diagonal circulation fastening in sequence, the assembler can fasten the bolt according to the order required by the diagonal circulation fastening of the bolt; the screw connection is needed between the static contact 73 and the static arc contact 74, the screw connection structure is provided, the predetermined torque needs to be applied to the screw connection structure, at this time the rotating disc 1, the fixed disc 2 and the static contact assembly can be driven to rotate along the second direction, the blocking pin 42 is clamped on the gear of the fixed disc 2, the rotation of the fixed disc 2 and the static contact assembly in the second direction is locked, the assembler uses the torque wrench to apply the predetermined torque to the screw connection structure along the second direction.
