Description

Technical Field

[0001] The invention belongs to the technical field of isolating switch assembly, and in particular relates to an automatic centering device and a centering method for an isolating switch. Background Art

[0002] At present, due to the particularity of high-voltage electrical products, the demand is low, manual assembly methods have been used for a long time, the degree of automation is low, and management is relatively extensive. Production enterprises have long maintained traditional production processes. However, the production of high-voltage SF6GIS has grown rapidly with the demand for electricity, and with the continuous research and development of production technology, in order to build a smart grid and realize the informatization, digitization and automation of the entire grid, the corresponding high-voltage electrical enterprises are required to increase the technical transformation of product production, improve product quality, and ensure the good market competitiveness of the enterprise. To this end, production enterprises have expanded their capacity and carried out technical transformation to innovate production capacity, manufacturing process and quality level.

[0003] The high-voltage electrical products currently developed by various manufacturers are mainly developing in the direction of full intelligence, and their equipment technology will become simple, saving time and effort. However, the high-voltage switch products themselves have a certain impact on the promotion of assembly technology, such as the variety, type and difficulty of batch assembly of products. These factors lead to more manual processes for the assembly of high-voltage products, and the assembly speed will also be subject to many restrictions. Therefore, in order to realize automatic assembly technology and reach or even exceed international standards, the assembly of high-voltage products urgently needs to develop in the direction of automation of assembly processes in industries such as instruments, electronics, and automobiles. Realizing high-tech assembly line production is also an important measure to achieve the internationalization of enterprises.

[0004] When assembling the moving side intermediate conductor and the static side intermediate conductor in the disconnector, it is necessary to ensure that the docking hole in the moving side intermediate conductor is aligned with the docking hole in the static side conductor with high precision. Since the moving side intermediate conductor is fixedly installed on the insulating basin on the moving side, and the static side intermediate conductor is fixedly installed on the insulating basin on the static side, the moving side intermediate conductor and the static side intermediate conductor generally need to rely on the insulating basins on both for angle positioning when they are aligned and assembled. Therefore, the accuracy of the relative position of the moving side intermediate conductor and the insulating basin during assembly and the accuracy of the relative position of the static side intermediate conductor and the insulating basin during assembly have a very important influence on the high precision alignment of the docking holes after the two are assembled. In the related art, when assembling the moving side intermediate conductor or the static side intermediate conductor and the insulating basin, a bolt thread locking method is generally adopted. Taking the assembly of the static side intermediate conductor as an example, generally the static side insulating basin is fixed first, and then the connection hole on the static side intermediate conductor is aligned with the connection hole on the insulating basin, and then the bolts are used to pass through the connection holes to lock and fix the two. However, the following problems are prone to occur during the above assembly process: on the one hand, the tightening operation itself is prone to deviations in the screwing direction, causing the position of the intermediate conductor relative to the insulating basin to change; on the other hand, since there are three intermediate conductors on the moving side and the static side, three bolts need to be used for tightening operations respectively, and the three tightening operations may affect each other, further increasing the probability of the position of the intermediate conductor relative to the insulating basin to change. As a result, it is easy to cause the relative position of the intermediate conductor and the insulating basin to deviate from the expected situation, thereby affecting the subsequent alignment assembly of the intermediate conductor on the moving side and the intermediate conductor on the static side.

[0005] The current existing technology uses two people to cooperate in manual assembly. The assembly uses tools such as jigs and mirrors to assist in alignment. The jigs are mainly used to clamp the conductor part that needs to be assembled into the jig to ensure the distance between each phase. The mirror is mainly used to observe the distance between the conductor periphery and the conductor seat. If the distance is not much different, it is considered to be aligned. However, when assembling the grounding end and the isolated static end, there will be a large gap. In this case, manual adjustment back and forth is required, which takes a lot of time, and there is uncertainty in the quality. The quality of manual assembly also varies from person to person, and the differences are large. Summary of the invention

[0006] The purpose of the present invention is to provide an automated centering device and a centering method for a disconnector, which solves the problem that the centering quality cannot be guaranteed by manual assembly and it takes a lot of time and energy.

[0007] The present invention is achieved through the following technical solutions:

[0008] The invention discloses an automatic centering device for a disconnector, comprising a frame, and a first mounting seat for positioning an insulating basin and a second mounting base for positioning an intermediate conductor, which are arranged on the frame;

[0009] A connecting frame is installed on the second mounting base, an elastic pressure mechanism and a six-component sensor are installed on the connecting frame, and a spacing between the elastic pressure mechanism and the first mounting seat is provided for inserting an intermediate conductor;

[0010] The six-component sensor has a force-bearing structure adapted to the docking hole of the intermediate conductor, and the force-bearing structure is used to be inserted into the docking hole of the intermediate conductor during the locking process of the intermediate conductor and the insulating basin;

[0011] The second mounting base is connected with a lifting drive mechanism for driving the second mounting base to move so as to adjust the distance between the middle conductor and the insulating basin;

[0012] The first mounting seat is provided with a first rotation driving mechanism for driving the first mounting seat to rotate; the second mounting seat is provided with a second rotation driving mechanism for driving the connecting frame to rotate.

[0013] Furthermore, a positioning groove matched with the insulating basin is provided on the first mounting seat, and is used to place the insulating basin in the positioning groove for positioning.

[0014] Furthermore, the elastic pressure mechanism includes a sliding column, an elastic member, a limit block and a pressure plate. The sliding column is slidably connected to the connecting frame. The pressure plate and the limit block are respectively fixed at both ends of the sliding column. The elastic member is arranged between the pressure plate and the connecting frame, and the elastic member applies pressure on the pressure plate so that the pressure plate has a tendency to move away from the connecting frame. The limit block is used to limit the sliding column from detaching from the connecting frame.

[0015] Furthermore, the elastic pressure mechanism also includes a connecting sleeve, which is installed through the connecting frame and is sleeved outside the sliding column.

[0016] Furthermore, the elastic member is a compression spring.

[0017] Further, the six-component sensor is connected to the connecting frame through a sliding connection mechanism;

[0018] The sliding connection mechanism includes a slide seat, a mounting block slidably arranged on the slide seat, and a linear driver arranged on the slide seat. The six-component sensor is fixedly arranged on the mounting block. The linear driver is connected to the mounting block and is used to drive the mounting block to move.

[0019] Furthermore, the force-bearing structure is in an annular shape, and the outer ring surface of the annular force-bearing structure is gap-matched with the inner ring wall of the docking hole of the intermediate conductor.

[0020] Furthermore, an elastic ring is provided between the outer ring surface of the force-bearing structure and the inner ring wall of the docking hole of the intermediate conductor, so as to protect the inner wall of the docking hole of the intermediate conductor.

[0021] Furthermore, the automated centering device further includes a controller, which is electrically connected to the first rotation drive mechanism, the lifting drive mechanism, and the second rotation drive mechanism, and is used to control the operation of the first rotation drive mechanism, the lifting drive mechanism, and the second rotation drive mechanism;

[0022] The controller is electrically connected to the six-component sensor and is used for receiving pressure data collected by the six-component sensor.

[0023] The present invention also discloses a centering method of the automated centering device, comprising the following process:

[0024] After the intermediate conductor is placed between the first mounting seat and the elastic pressure mechanism and aligned with the insulating basin, the second mounting seat is driven down by the lifting drive mechanism, and the second mounting seat drives the connecting frame and the elastic pressure mechanism disposed on the connecting frame to descend until the elastic pressure mechanism contacts the top end of the intermediate conductor and elastically presses the top end of the intermediate conductor;

[0025] Pre-tighten the intermediate conductor and the insulating basin; during the pre-tightening operation, first pre-tighten one of the intermediate conductors, then drive the first mounting seat to rotate through the first rotation drive mechanism, and simultaneously drive the connecting frame to rotate through the second rotation drive mechanism, so as to drive the insulating basin, the intermediate conductor, the elastic pressure mechanism and the six-component sensor to rotate synchronously; then pre-tighten the remaining intermediate conductors;

[0026] The six-component sensor is driven to slide so that the force-bearing structure on the six-component sensor is plugged into the docking hole of the intermediate conductor; during the plugging process, if the intermediate conductor is slightly offset relative to the expected position during the aforementioned pre-tightening operation, the force-bearing structure in the six-component sensor with a set posture acts on the inner wall of the docking hole through the plugging operation to drive the intermediate conductor to slightly deviate and return to the expected position; thereafter, one of the intermediate conductors is fully tightened;

[0027] Then, the first mounting seat and the connecting frame are synchronously driven to rotate by the first rotation driving mechanism and the second rotation driving mechanism, thereby driving the insulating basin, the middle conductor, the elastic pressure mechanism and the six-component sensor plugged into the docking hole of the middle conductor to synchronously rotate;

[0028] Finally, the remaining intermediate conductors that have not yet been fully tightened are fully tightened.

[0029] Compared with the prior art, the present invention has the following beneficial technical effects:

[0030] The invention discloses an automatic centering device for disconnectors, comprising a first mounting seat and a second mounting seat, wherein the first mounting seat is used to position an insulating basin, and a connecting frame is installed on the second mounting seat, wherein an elastic pressure mechanism and a six-component sensor are installed on the connecting frame, and the elastic pressure mechanism is used to apply pressure to an intermediate conductor placed on the insulating basin by arranging the elastic pressure mechanism and the six-component sensor to cooperate, so that the intermediate conductor placed on the insulating basin can be positioned to a certain extent to prevent the intermediate conductor from shaking greatly during the process of screwing the bolts; on the other hand, the intermediate conductor can be allowed to adjust its position in a small range. By plugging the six-component sensor with a pre-designed angle posture into the docking hole in the intermediate conductor, the six-component sensor can be used to correct the position of the intermediate conductor. If a certain deviation occurs in the intermediate conductor relative to the insulating basin during the placement process or the assembly process, the force structure in the fixed position six-component sensor can be used to correct the position of the intermediate conductor. In addition, after the assembly is completed, the measurement data of the six-component sensor can also be used to judge whether the relative position between the intermediate conductor and the insulating basin meets the assembly expectation, and the six-component sensor can also play a role in detection and verification.

[0031] A first rotating drive mechanism is arranged on the first mounting seat to drive the first mounting seat to rotate, and then drive the insulating basin to rotate; a second rotating drive mechanism is arranged on the second mounting seat to drive the connecting frame to rotate, and then drive the intermediate conductor to rotate; through the synchronous rotation of the two rotating drive mechanisms, it is ensured that the insulating basin, the intermediate conductor, the elastic pressure mechanism that elastically applies pressure to the intermediate conductor and the six-component sensor complete the rotation synchronously.

[0032] Furthermore, the sliding column is slidably connected to the connecting frame, the pressure plate is fixed to one end of the sliding column, and the elastic member is located between the pressure plate and the connecting frame. The function of the elastic member is to make the pressure plate tend to move away from the connecting frame, thereby applying pressure to the intermediate conductor. This elastic pressure method can adaptively adjust the pressure within a certain range to adapt to the possible dimensional errors, installation position deviations, etc. of the intermediate conductor, to ensure stable contact and pressure effects. The elastic pressure mechanism can make the pressure distribution of the pressure plate on the surface of the intermediate conductor relatively uniform. Compared with the rigid direct pressure method, the presence of the elastic member allows the pressure plate to be adaptively adjusted according to the actual situation of the surface of the intermediate conductor, so that the pressure on the entire contact surface is more balanced.

[0033] Furthermore, the mounting block can slide on the slide, and the six-component sensor is fixed on the mounting block, which enables the six-component sensor to flexibly change its position within the range defined by the slide. In practical applications, it may be necessary to adjust the position of the sensor according to different measurement scenarios, the position of the target object, or the overall layout of the measurement system to obtain more accurate and effective measurement data; by driving the mounting block to move through the linear drive, the position change of the sensor can be precisely controlled.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, not all embodiments.

[0046] The components described and shown in the drawings and embodiments of the present invention may be arranged and designed in various configurations. Therefore, the detailed description of the embodiments of the present invention provided in the following drawings is not intended to limit the scope of the claimed invention, but merely represents a selected embodiment of the present invention. Based on the drawings and embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] It should be noted that the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, element, method, article or equipment that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to the process, element, method, article or equipment.

[0048] The features and performances of the present invention are further described in detail below in conjunction with the embodiments.

[0049] The present invention provides an automated centering device for an isolating switch, which can be used to assemble the intermediate conductor 7 in the isolating switch with the insulating basin. The intermediate conductor 7 can be either a static side intermediate conductor or a dynamic side intermediate conductor, both of which need to be assembled with the insulating basin. The automated centering device includes a frame 1, a first mounting seat 2, an elastic pressure mechanism 5, and a six-component sensor 6. Among them, the first mounting seat 2 is arranged on the frame 1 and is used to position the insulating basin, and the insulating basin is in the shape of a disc. The first mounting seat 2 is provided with a positioning groove adapted to the insulating basin, and the insulating basin can be placed in the positioning groove for positioning. The elastic pressure mechanism 5 in the present invention is arranged on the frame 1, located above the first mounting seat 2, and located below the second mounting seat 3. There is a spacing between the first mounting seat 2 and the elastic pressure mechanism 5 for inserting the intermediate conductor 7, and the elastic pressure mechanism 5 is used to elastically apply pressure to the intermediate conductor 7 placed on the insulating basin.

[0050] Specifically, the elastic pressure means that: on the one hand, the pressure applied by the elastic pressure mechanism 5 to the intermediate conductor 7 can maintain a certain stability of the intermediate conductor 7, so that the intermediate conductor 7 will not be displaced to a large extent during the process of screwing the intermediate conductor 7 to the insulating basin. On the other hand, the elastic pressure can allow the intermediate conductor 7 to be slightly displaced during the tightening and assembly process.

[0051] The six-component sensor 6 in the present invention is connected to the connecting frame 4 and has a set posture relative to the frame 1. The six-component sensor 6 has a force-bearing structure 60 that is compatible with the docking hole 70 of the intermediate conductor 7, and the force-bearing structure 60 is used to be inserted into the docking hole 70 of the intermediate conductor 7 during the locking process of the intermediate conductor 7 and the insulating basin. Since the elastic pressure-applying mechanism 5 elastically applies pressure to the intermediate conductor 7, the intermediate conductor 7 is allowed to be slightly displaced during the tightening and assembly process. By plugging the six-component sensor 6 with a set posture into the docking hole 70 in the intermediate conductor 7, the six-component sensor 6 can be used to perform position correction calibration on the intermediate conductor 7.

[0052] The six-component sensor 6 and the elastic pressure-applying mechanism 5 are arranged relatively on both sides of the conductor 7 . The elastic pressure-applying mechanism 5 fixes the upper end or the side of the conductor 7 . The six-component sensor 6 is docked in the three-phase hole of the conductor 7 .

[0053] Specifically, if the intermediate conductor 7 has a certain deviation relative to the insulating basin during the placement process or the assembly process (pre-tightening process), the force-bearing structure 60 in the fixed-position six-component sensor 6 can be used to correct the position of the intermediate conductor so that the intermediate conductor 7 is slightly displaced and is in the expected position. In addition, after the assembly is completed, the measurement data of the six-component sensor 6 can also be used to determine whether the relative position between the intermediate conductor 7 and the insulating basin meets the assembly expectations, that is, the six-component sensor 6 can also play a detection and verification role.

[0054] The automated centering device of the present invention further includes a second mounting seat 3 disposed on the frame 1, and the elastic pressure mechanism 5 and the six-component sensor 6 are both disposed on the second mounting seat 3. The automated centering device further includes a lifting drive mechanism 10 disposed on the frame 1, and the lifting drive mechanism 10 is connected to the second mounting seat 3 through a transmission chain, and is used to drive the second mounting seat 3 to move so as to adjust the spacing between the intermediate conductor 7 and the insulating basin. Through the above-mentioned arrangement, the second mounting seat 3 capable of being lifted and lowered is used to drive the elastic pressure mechanism 5 and the six-component sensor 6 to rise and fall synchronously, which, on the one hand, facilitates the elastic pressure mechanism 5 and the six-component sensor 6 to move relative to the intermediate conductor 7 during the assembly operation, so as to facilitate the placement of the intermediate conductor 7, the abutment and pressure of the elastic pressure mechanism 5 relative to the intermediate conductor 7, and the plugging operation of the six-component sensor 6; on the other hand, it enables the automated centering device to adapt to intermediate conductors 7 of different lengths.

[0055] The frame 1 in the present invention is provided with a first rotary drive mechanism 11, which is connected to the first mounting seat 2 and is used to drive the first mounting seat 2 to rotate. Through the above arrangement, the first rotary drive mechanism 11 can be used to drive the insulating basin positioned on the first mounting seat 2 to rotate through the first mounting seat 2. The advantage of this design is that, due to the placement of the three intermediate conductors 7 relative to the insulating basin, the connection points of two intermediate conductors 7 are located on both sides of the connection point of another intermediate conductor 7. In this way, for the automatic assembly mechanism used to thread the intermediate conductors 7 and the insulating basin, when performing the tightening assembly operation, the automatic assembly mechanism is prone to interfere with the frame 1 or other components. Through the above design, after the tightening assembly of part of the intermediate conductors 7 is completed, the first mounting seat 2 is driven to rotate so that the points on the insulating basin that have not been tightened and assembled are rotated to a position that is convenient for the automatic assembly mechanism to perform the tightening operation. In this way, the difficulty of the assembly operation can be reduced and the damage caused by collision can be reduced.

[0056] like Figure 1 As shown, in the present invention, a second rotation drive mechanism 30 and a connecting frame 4 that can rotate driven by the second rotation drive mechanism 30 are also provided on the second mounting seat 3, and the elastic pressure mechanism 5 and the six-component sensor 6 are both provided on the connecting frame 4, and the connecting frame 4 is installed on the lower side of the second mounting seat 3. By providing the second rotation drive mechanism 30 and the connecting frame 4, when the first mounting seat 2 rotates, the connecting frame 4 can be synchronously driven to drive the elastic pressure mechanism 5 and the six-component sensor 6 to rotate. In this way, Figure 8 As shown, when the insulating basin and the intermediate conductor 7 need to be rotated synchronously, the first rotation drive mechanism 11 and the second rotation drive mechanism 30 can be controlled to work synchronously to drive the first mounting seat 2 and the connecting frame 4 to rotate synchronously, thereby driving the insulating basin, the intermediate conductor 7, the elastic pressure mechanism 5 that elastically applies pressure to the intermediate conductor 7, and the six-component sensor 6 plugged into the docking hole 70 of the intermediate conductor 7 to complete the rotation synchronously.

[0057] Combination Fig. 9 and Fig.10As shown in the figure, the elastic pressure mechanism 5 in the present invention includes a sliding column 51, an elastic member 52, a limit block 53 and a pressure plate 50. The sliding column 51 is slidably arranged on the connecting frame 4, the pressure plate 50 and the limit block 53 are respectively fixedly arranged at both ends of the sliding column 51, the elastic member 52 is arranged between the pressure plate 50 and the connecting frame 4, and the elastic member 52 presses the pressure plate 50 so that the pressure plate 50 has a tendency to move away from the connecting frame 4, and the limit block 53 is used to limit the sliding column 51 from leaving the connecting frame 4. Through the above arrangement, under the action of the elastic member 52, the pressure plate 50 drives the sliding column 51 to have a tendency to slide downward, but due to the limitation of the limit block 53, the sliding column 51 cannot slide downward excessively, so that it can maintain a balanced state when not affected by external forces. When the pressure plate 50 abuts against the intermediate conductor 7 and applies pressure to the intermediate conductor 7 , the pressure plate 50 can not only apply pressure to the intermediate conductor 7 , but also allow the intermediate conductor 7 to be slightly displaced under sufficient external force through the self-adaptation of the elastic member 52 .

[0058] In order to increase the stability of the sliding of the sliding column 51 relative to the connecting frame 4, a connecting sleeve 54 is also provided. The connecting sleeve 54 passes through the connecting frame 4 and is fixedly installed on the connecting frame 4. At the same time, the connecting sleeve 54 is sleeved outside the sliding column 51, and the sliding column 51 and the connecting sleeve 54 are clearance-matched. Among them, the elastic member 52 is a compression spring, which is sleeved outside the sliding column 51, and the lower end of the compression spring abuts on the pressure plate 50, and the upper end of the compression spring abuts on the lower end surface of the connecting sleeve 54. The lower end of the sliding column 51 is fixedly connected to the pressure plate 50 by a set screw, and the upper end of the sliding column 51 is fixedly connected to the limit block 53 by a set screw.

[0059] The six-component sensor 6 of the present invention is slidably disposed on the frame 1 in a set posture. Specifically, in this embodiment, the six-component sensor 6 is Figure 6 , Figure 7 and Fig. 9 As shown in , the automated centering device further includes a slide 40 fixedly arranged on the connecting frame 4, a mounting block 42 slidably arranged on the slide 40, and a linear driver 41 arranged on the slide 40. The six-component sensor 6 is fixedly arranged on the mounting block 42, and the linear driver 41 is connected to the mounting block 42 and is used to drive the mounting block 42 to move. Through the above arrangement, the stability of the sliding of the six-component sensor 6 can be ensured, and it can ensure that it can maintain the set posture.

[0060] The automated centering equipment in the present invention also includes a controller, which is electrically connected to the first rotary drive mechanism 11, the lifting drive mechanism 10 and the second rotary drive mechanism 30 and is used to control the operation of the first rotary drive mechanism 11, the lifting drive mechanism 10 and the second rotary drive mechanism 30. The controller is electrically connected to the six-component sensor 6 and is used to receive pressure data collected by the six-component sensor 6.

[0061] Combination Figure 4 and Figure 6 As shown in the figure, the force-bearing structure 60 in the present invention is in an annular shape, and the outer ring surface of the annular force-bearing structure 60 is gap-matched with the inner ring wall of the docking hole 70 of the intermediate conductor 7. Designing the force-bearing structure 60 in an annular shape can better realize the correction calibration and "detection verification" functions. In other optional implementations, the force-bearing structure 60 can also be designed as a truncated cone, a rectangular structure, etc., as long as its edge portion can be effectively matched with the inner wall of the docking hole 70 of the intermediate conductor 7 along the circumferential direction.

[0062] More preferably, an elastic ring is provided between the outer ring surface of the force-bearing structure 60 and the inner ring wall of the docking hole 70 of the intermediate conductor 7. The elastic ring may be a rubber ring, and the elastic ring may be provided on the inner ring wall of the docking hole 70 of the intermediate conductor 7, or the elastic ring may be provided on the outer ring surface of the force-bearing structure 60. Specifically, a mounting groove may be provided on the inner ring wall of the docking hole 70 or on the outer ring surface of the force-bearing structure 60, and the elastic ring may be fixed in the mounting groove. The deformation effect of the elastic ring may be utilized to improve the plug-in matching accuracy between the force-bearing structure 60 and the docking hole 70 of the intermediate conductor 7, so as to better realize the aforementioned deviation correction calibration and detection verification functions.

[0063] like Figure 2 As shown in FIG. 1 , in the initial state, the second mounting seat 3 and the first mounting seat 2 have a sufficient spacing value, so that the elastic pressure mechanism 5 and the insulating basin positioned on the first mounting seat 2 have a sufficient spacing, so that the three intermediate conductors 7 can be placed between the first mounting seat 2 and the elastic pressure mechanism 5. Figure 3 and Figure 4 As shown in the figure, the robot holds the intermediate conductor, places the intermediate conductor 7 between the first mounting seat 2 and the elastic pressure mechanism 5 and aligns it with the insulating basin, and then drives the second mounting seat 3 to descend through the lifting drive mechanism 10, driving the connecting frame 4 and the elastic pressure mechanism 5 arranged on the connecting frame 4 to descend, until the elastic pressure mechanism 5 contacts the top of the three intermediate conductors 7 and elastically presses the intermediate conductor 7. After that, the robot is used to pre-tighten the intermediate conductor 7 and the insulating basin. During the pre-tightening operation, the pre-tightening operation can be performed on some of the intermediate conductors 7 first, and then the first mounting seat 2 and the connecting frame 4 are synchronously driven to rotate by the first rotation drive mechanism 11 and the second rotation drive mechanism 30, thereby driving the insulating basin, the intermediate conductor 7, the elastic pressure mechanism 5 elastically pressurizing the intermediate conductor 7, and the six-component sensor 6 to complete the rotation synchronously. Then the remaining intermediate conductors 7 are pre-tightened.

[0064] Combination Figure 5 , Figure 6 and Figure 7As shown in , the six-component sensor 6 is installed on the connecting frame 4, and the six-component sensor 6 is driven to slide by driving the connecting frame 4, so that the force-bearing structure 60 on the six-component sensor 6 is plugged into the docking hole 70 of the intermediate conductor 7. In the plug-in process, since the six-component sensor 6 has the aforementioned set posture, if the intermediate conductor 7 is slightly offset relative to the expected position during the aforementioned pre-tightening operation, the above-mentioned plug-in operation can be used to utilize the force-bearing structure 60 in the six-component sensor 6 with the set posture to interact with the inner wall of the docking hole 70, so as to drive the intermediate conductor 7 to slightly deviate and return to the expected position. Afterwards, an automated assembly mechanism is used to fully tighten some of the intermediate conductors 7 (one or two). Combined with Figure 8 As shown in the figure, the first mounting seat 2 and the connecting frame 4 are synchronously driven to rotate by the first rotation drive mechanism 11 and the second rotation drive mechanism 30, thereby driving the insulating basin, the intermediate conductor 7, the elastic pressure mechanism 5 elastically pressing the intermediate conductor 7, and the six-component sensor 6 inserted into the docking hole 70 of the intermediate conductor 7 to synchronously rotate. Then, the remaining intermediate conductors 7 that have not been fully tightened are fully tightened.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
