Description

Technical Field

[0001] This utility model belongs to the technical field of inertial testing equipment, specifically a coupling for a three-dimensional inertial testing turntable. Background Technology

[0002] When conducting three-dimensional inertial testing in fields such as aerospace, automotive, and electronics, a three-dimensional turntable is typically used. The three-dimensional turntable can be used to simulate the angular motion or angular position changes of objects (mainly aircraft, missiles, ships, vehicles, and other carriers) in space, thereby achieving the effect of inertial detection.

[0003] For example, utility model CN219170836U discloses a combined three-dimensional turntable, including a rotating base and an assembly device. A support base is positioned above the rotating base, and a second rotating base is positioned on one side of the support base. The second support is rotatably connected to the inner wall of the first support. The output end of the second rotating base is fixedly connected to the support. A third rotating base is positioned on the surface of the second support. The assembly device is positioned on the surface of the rotating base. The assembly device includes two cross blocks, both of which are fixedly connected to the surface of the first rotating base. By providing the assembly device, the equipment can be quickly assembled, effectively reducing the need to use tools to tighten multiple bolts during assembly, thus minimizing operational hassles and time-consuming processes. This also reduces slow assembly speeds and inefficiencies, thereby improving the overall usability of the equipment.

[0004] Existing technologies have solved the problem of slow equipment assembly speed, but existing shaft structures require rotation angles to align with the central platform when being assembled, and cannot automatically guide alignment, resulting in a longer installation time. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a dedicated coupling for a three-dimensional inertial testing turntable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special coupling for a three-dimensional inertial testing turntable, comprising a molded frame, wherein guide locking components are spliced ​​on the inner sides of both ends of the molded frame;

[0007] The guide locking assembly includes a platform, and splicing seats are assembled on both sides of the platform. Two sets of guide arc plates are installed on the inner side of the splicing seats away from the platform. A coupling is spliced ​​on the side of the splicing seats away from the platform. A movable block is movably arranged on the inner side of the coupling near the splicing seat. Four sets of drive rods are rotatably arranged on the side of the movable block away from the splicing seat. A push rod is rotatably arranged on the outer side of the end of the drive rod. A locking arc plate is rotatably arranged on the outer side of the push rod away from the drive rod. The locking arc plate is movably embedded in the inner side of the splicing seat.

[0008] Preferably, a top rod is fixedly installed on the side of the movable block away from the drive rod, and the top rod is movably disposed on the inner side of the coupling near the splicing seat. A strong spring is installed on the side of the movable block away from the top rod, and the strong spring is movably disposed in the middle of the four sets of drive rods.

[0009] Preferably, the drive rod is provided with limit plates on both sides of the end away from the push rod, and the limit plates are fixedly provided on the side of the movable block away from the top rod. The push rod is provided with three sets of combination plates on the outer side of the end away from the drive rod, and the combination plates are fixedly installed on the side of the locking arc plate near the push rod.

[0010] Preferably, four sets of arc-shaped slots are provided on the side of the splicing seat near the coupling, the locking arc plate is spliced ​​on the inner side of the arc-shaped slots, and a limit groove is provided between the two sets of the guide arc plates.

[0011] Preferably, a drive groove is provided on the inner side of the coupling away from the splicing seat, and several sets of flexible discs are embedded in the middle of the coupling by bolts. A limit sleeve is installed on the end of the coupling away from the drive groove. The movable block and the top rod are movably arranged inside the limit sleeve. Sliding rods are fixedly installed on both sides of the limit sleeve, and the sliding rods are movably located inside the limit groove.

[0012] Preferably, the bottom of the frame is provided with an installation groove, and the outer side of the upper end of the frame is provided with a bearing groove, and the outer side of the upper end of the frame is provided with a stepped combination groove, which is located outside the bearing groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the combination of a guide locking component and a combined motor, facilitates the quick alignment of the coupling with the installation position via a guide arc plate structure and a sliding rod, thereby shortening installation time. Simultaneously, a pressing mechanism drives the internal locking structure for rapid locking, increasing post-assembly stability. The splicing seat provides the splicing position for the coupling, while the inner guide arc plate restricts the sliding rod. Continuous pressing after the sliding rod contacts the guide arc plate causes it to slide along the arc structure, adjusting the coupling angle for alignment. Furthermore, the coupling and the limiting sleeve restrict the internal structure. Pressing the top rod into the limiting sleeve causes the movable block to extend the various drive rods and push rods, which in turn causes the locking arc plate to move along the opened arc slot. Locking is achieved by embedding it into the splicing seat, effectively improving post-assembly stability. Simultaneously, installation can be performed directly without angle adjustment, and automatic calibration reduces worker workload. Attached Figure Description

[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] like Figures 1 to 7 As shown, this utility model provides a special coupling for a three-dimensional inertial test turntable, including a frame 100, and guide locking components 001 are spliced ​​on the inner sides of both ends of the frame 100.

[0030] The guide locking assembly 001 includes a platform 300, and splicing seats 301 are assembled on both sides of the platform 300. Two sets of guide arc plates 303 are installed on the inner side of the splicing seats 301 away from the platform 300. A coupling 400 is spliced ​​on the side of the splicing seats 301 away from the platform 300. A movable block 501 is movably arranged on the inner side of the end of the coupling 400 near the splicing seat 301. Four sets of drive rods 505 are rotatably arranged on the side of the movable block 501 away from the splicing seat 301. A push rod 506 is rotatably arranged on the outer side of the end of the drive rod 505. A locking arc plate 500 is rotatably arranged on the outer side of the push rod 506 away from the end of the drive rod 505. The locking arc plate 500 is movably embedded in the inner side of the splicing seat 301.

[0031] A top rod 502 is fixedly installed on the side of the movable block 501 away from the drive rod 505. The top rod 502 is movably located on the inner side of the coupling 400 near the splicing seat 301. A strong spring 503 is installed on the side of the movable block 501 away from the top rod 502, and the strong spring 503 is movably located in the middle of the four sets of drive rods 505.

[0032] The above solution is adopted: the platform 300 serves as the main detection structure. It can be spliced ​​to the side of the platform 300 using the splicing seat 301. After splicing, it provides an installation position for the outer coupling 400. The guide arc plate 303 provides constraint and guidance for the sliding rod 404. The coupling 400 can transmit kinetic energy. Furthermore, during the assembly process of the coupling 400 and the platform 300, the coupling 400 shaft structure, which requires adjustment of the gap between parts in a free state, solves the problems of transmission accuracy and shaft stability in the multi-degree-of-freedom motion of the three-dimensional turntable. Through the coordinated design of the stepped shafts of the couplings 400 at both ends, high torsional stiffness is ensured while achieving… The shaft connection under three-dimensional motion is self-matching and self-compensating to eliminate errors. By using the drive rod 505 and push rod 506, the locking arc plate 500 can be moved outward along the inner arc area. After being outward, it will be embedded in the inner side of the arc slot 302. When the coupling 400 and the splicing seat 301 are installed, the compression will push the top rod 502 and the movable block 501 to slide along the inner side of the limit sleeve 403, thereby achieving the effect of driving the locking arc plate 500 to adjust. The strong spring 503 can push the movable block 501 to reset when the flange on the outside of the coupling 400 and the combined motor 200 are disassembled, thereby separating the coupling 400 from the splicing seat 301.

[0033] like Figures 4-6 As shown, limit plates 504 are rotatably provided on both sides of the end of the drive rod 505 away from the push rod 506, and the limit plates 504 are fixedly provided on the side of the movable block 501 away from the top rod 502. Three sets of combination plates 507 are rotatably provided on the outer side of the end of the push rod 506 away from the drive rod 505, and the combination plates 507 are fixedly installed on the side of the locking arc plate 500 near the push rod 506.

[0034] Four sets of arc-shaped slots 302 are provided on the side of the splicing base 301 near the coupling 400. The locking arc plate 500 is spliced ​​and set inside the arc-shaped slot 302. A limit groove 304 is provided between the two sets of guide arc plates 303.

[0035] A drive groove 401 is provided on the inner side of the coupling 400 away from the splicing seat 301, and several sets of flexible discs 402 are embedded in the middle of the coupling 400 by bolts. A limit sleeve 403 is installed on the end of the coupling 400 away from the drive groove 401. The movable block 501 and the push rod 502 are movably arranged inside the limit sleeve 403. Sliding rods 404 are fixedly installed on both sides of the limit sleeve 403, and the sliding rods 404 are movably located inside the limit groove 304.

[0036] Using the above scheme: the limiting plate 504 can restrict the drive rod 505, and the drive rod 505 can control the extension of the push rod 506. During the extension process, it can assist the combination plate 507 in pushing the locking arc plate 500 to extend, thereby achieving a fast locking effect. The arc slot 302 can restrict the locking arc plate 500. It should be noted that the arc surface of the arc slot 302 is larger than the locking arc plate 500. After the locking arc plate 500 is inserted into the inner side of the arc slot 302, there is a gap in the arc area to avoid interference during adjustment. The limiting groove 304 can restrict the calibrated sliding rod 404 to maintain its positioning. The drive groove 401 can provide a splicing position for the drive shaft of the combination motor 200. The combination can then transmit kinetic energy. The flexible disc 402 and the bolt can achieve the effect of self-matching error self-compensation and elimination of shaft connection under three-dimensional motion. The sliding rod 404 can contact the guide arc plate 303 to adjust the angle of the coupling 400.

[0037] like Figure 1 and Figure 2 As shown, the bottom of the frame 100 is provided with a mounting groove 101, and the outer side of the upper end of the frame 100 is provided with a bearing groove 102. The outer side of the upper end of the frame 100 is provided with a stepped combination groove 103, which is located outside the bearing groove 102.

[0038] A combined bearing 201 is spliced ​​on the inner side of the bearing groove 102, a first flange 202 is spliced ​​on the inner side of the stepped combined groove 103, and a second flange 203 is spliced ​​on the inner side of the stepped combined groove 103. The second flange 203 is located outside the first flange 202. The first flange 202 and the second flange 203 are fixed to the frame 100 by positioning bolts 204. A combined motor 200 is bolted to the outer side of the second flange 203.

[0039] The above solution is adopted: the bearing groove 102 can provide an installation position for the inner combined bearing 201, and the splicing shaft can assist the coupling 400 in rotational adjustment. The stepped combined groove 103 can provide an installation position for the first flange 202 and the second flange 203. After splicing, the stability of the structure can be guaranteed. After locking with the positioning bolt 204, the stability of the splicing can be effectively maintained. Then, the combined motor 200 is spliced ​​using the bolt structure. After splicing, it can be powered to drive the coupling 400 at the output end to rotate and adjust.

[0040] The working principle and usage process of this utility model are as follows: First, insert the coupling 400 into the inner side of the bearing groove 102 from the inner side of the frame 100. Then, splice the combined bearing 201 onto the inner side of the bearing groove 102 and fix it using the first flange 202 and the second flange 203. After fixing, place the platform 300 in the middle of the frame 100. Then, splice the combined motor 200 onto the outer side of the second flange 203. During the assembly process, the output shaft of the combined motor 200 drives the inner side of the groove 401 and pushes the coupling 400 into place. Inside the splicing base 301, during continuous insertion, the sliding rod 404 will slide along the guide arc plate 303. After sliding to the inside of the limiting groove 304, continued pressing will push the top rod 502 into the inside of the limiting sleeve 403. After entering the interior, the movable block 501 will push the drive rod 505 and the push rod 506 outward. During the outward extension, the locking arc plate 500 will flip along the inner arc structure and insert into the inner side of the arc slot 302 for locking. After the splicing is completed, the combined motor 200 and the outer side of the second flange 203 are fixed by bolt structure.
