Description

Technical Field

[0001] This utility model relates to the field of precision positioning fixture technology, and in particular to a precision positioning fixture for satellite antenna assembly. Background Technology

[0002] Precision positioning fixtures play a crucial role in the assembly of satellite antennas, but traditional satellite antenna assembly positioning fixtures have many drawbacks.

[0003] On the one hand, most positioning fixtures have extremely limited angle adjustment functions, and can only achieve simple fixed angle adjustment. This makes it difficult to meet the needs of satellite antennas for precise multi-angle positioning in different assembly stages. As a result, antenna components are difficult to align precisely during assembly, which increases the difficulty of assembly, makes assembly errors more likely, and seriously affects the performance of satellite antennas.

[0004] On the other hand, existing clamps often use rigid clamping methods when holding satellite antennas, which cannot adaptively adjust according to the shape and contour of the antenna. For some irregularly shaped or fragile satellite antennas, rigid clamping can easily cause scratches, deformation and other damage to the antenna surface, which not only reduces product quality but also increases production costs. At the same time, some positioning clamps require operators to frequently manually adjust multiple components during operation, which is cumbersome and complicated. This not only consumes a lot of time and manpower but also poses certain safety risks to operators during operation, such as being pinched by moving parts, increasing safety hazards. In addition, traditional positioning clamps lack versatility when dealing with satellite antennas of different sizes and specifications, requiring frequent clamp replacements or large-scale modifications to the clamps, further reducing production efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that some satellite antennas with irregular shapes or fragile materials are easily damaged by rigid clamping, such as scratches and deformation on the antenna surface. Therefore, a precision positioning fixture for satellite antenna assembly is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a precision positioning fixture for satellite antenna assembly, comprising: a fixture mounting base, a first sleeve fixedly connected to the top of the fixture mounting base, a rotating ring fixedly connected to the top of the first sleeve, and an angle adjustment mechanism provided on the top of the rotating ring; the angle adjustment mechanism includes a semi-circular slide rail, the outer wall of the semi-circular slide rail being provided with a semi-circular slide rail, an angle measuring scale being provided on the outer surface of the semi-circular slide rail, a mounting platform fixedly connected to the top of the semi-circular slide rail, and a semi-circular gear ring fixedly connected to the outer wall of the mounting platform. A set of sliding brackets is movably arranged inside the semi-circular slide rail, a mounting shell is fixedly connected to the top of each sliding bracket, a worm gear meshes with the outer wall of the semi-circular gear ring, two fixed rings are rotatably connected to the outer wall of the worm gear, and an adjustment knob is fixedly connected to one end of the worm gear.

[0007] Preferably, a first motor is fixedly connected to the top of the mounting housing, a support ring is fixedly connected to the output end of the first motor, a fixed ring is rotatably connected to the outer wall of the support ring, a sliding seat is fixedly connected to the top of the mounting housing, and two movable plates are threadedly connected to the outer wall of the support ring.

[0008] Preferably, a flexible clamping mechanism is provided on the top of both movable plates; the flexible clamping mechanism includes a fixed plate, and a second sleeve is fixedly connected to the outer surface of the fixed plate.

[0009] Preferably, a spring is fixedly installed inside the second sleeve, one end of the spring is fixedly connected to a clamping post, and a limit plate is slidably connected to the outer wall of the clamping post.

[0010] Preferably, the bottom of the semicircular slide rail and the top of the rotating ring are rotatably connected, and the bottom of the semicircular slide rail is fixedly connected to the output end of the second motor.

[0011] Preferably, the second motor is disposed inside the first sleeve, and the outer surfaces of the two fixing rings are fixedly connected to the bottom of the mounting housing.

[0012] Preferably, the bottom of the fixed plate and the top of the movable plate are fixedly connected, and the bottoms of both movable plates are slidably connected to the outer wall of the sliding seat.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the second motor drives the semi-circular slide rail to rotate around the rotating ring. With the help of the angle measuring ruler, the overall angle of the satellite antenna can be quickly and coarsely adjusted. Then, by using the meshing of the worm gear and the semi-circular gear ring, the angle can be finely adjusted by rotating the adjustment knob. This greatly improves the accuracy and flexibility of angle adjustment, meets the stringent requirements for multi-angle precision positioning during satellite antenna assembly, effectively reduces assembly errors, improves product performance, and at the same time reduces the frequency of manual adjustment by operators, thus reducing safety risks.

[0015] 2. In this utility model, the unique flexible clamping mechanism utilizes the elasticity of the spring to allow the clamping column to automatically adjust the clamping force according to the shape of the satellite antenna, achieving flexible and stable clamping of the antenna. This avoids damage to the antenna caused by rigid clamping, improves product quality, and the first motor drives the support ring to rotate. In conjunction with the threaded connection between the support ring and the moving plate, the position and orientation of the moving plate and the flexible clamping mechanism can be flexibly adjusted to adapt to the clamping requirements of satellite antennas of different sizes and shapes. This enhances the versatility of the clamp, reduces safety hazards caused by operators frequently changing or modifying clamps, and improves production efficiency. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Please refer to... Figures 1-6 As shown, this utility model provides a precision positioning fixture for satellite antenna assembly, including: a fixture mounting base 1, a first sleeve 2 fixedly connected to the top of the fixture mounting base 1, a rotating ring 3 fixedly connected to the top of the first sleeve 2, and an angle adjustment mechanism 4 provided on the top of the rotating ring 3; the angle adjustment mechanism 4 includes a semi-circular slide rail 401, a semi-circular slide rail 401 is provided on the outer wall of the semi-circular slide rail 401, an angle measuring scale 402 is provided on the outer surface of the semi-circular slide rail 401, an installation platform 403 is fixedly connected to the top of the semi-circular slide rail 401, and a semi-circular toothed ring 404 is fixedly connected to the outer wall of the installation platform 403. The semicircular slide rail 401 has a set of sliding brackets 405 inside. The top of each sliding bracket 405 is fixedly connected to the mounting housing 406. The outer wall of the semicircular gear ring 404 is engaged with a worm gear 407. The outer wall of the worm gear 407 is rotatably connected to two fixed rings 408. One end of the worm gear 407 is fixedly connected to an adjustment knob 409. The bottom of the semicircular slide rail 401 is rotatably connected to the top of the rotating ring 3. The bottom of the semicircular slide rail 401 is fixedly connected to the output end of the second motor 7.

[0026] The overall effect of Embodiment 1 is that, by setting the angle adjustment mechanism 4, the crucial multi-angle positioning function in the satellite antenna assembly process is realized. The rotational connection between the semi-circular slide rail 401 and the rotating ring 3, combined with the drive of the second motor 7 at the bottom, allows the semi-circular slide rail 401 to rotate flexibly, providing basic support for antenna angle adjustment. The angle measuring scale 402 on the semi-circular slide rail 401 acts like a precise navigator, allowing operators to intuitively and accurately control the antenna angle adjustment range based on the scale, greatly improving the accuracy and operability of angle adjustment. The semi-circular gear ring 404 and the worm gear 4 on the mounting platform 403... The meshing design of the 07 is ingenious. When the adjustment knob 409 is turned, the worm gear 407 rotates accordingly, which in turn drives the semi-circular gear ring 404 to rotate, causing the mounting platform 403 and related components to make fine-tuning adjustments to the angle. This fine-tuning mechanism, together with the overall rotation of the semi-circular slide rail 401, allows the satellite antenna to achieve extremely high precision in multi-angle positioning, meeting the stringent requirements of satellite antenna assembly for precise positioning. At the same time, the two fixed rings 408 provide stable support and rotation limit for the worm gear 407, ensuring the stability and reliability of the entire angle adjustment process, and laying a solid foundation for the subsequent precise assembly of the satellite antenna.

[0027] Example 2: Please refer to... Figures 1-6 As shown, a first motor 5 is fixedly connected to the top of the mounting housing 406. A support ring 52 is fixedly connected to the output end of the first motor 5. A fixed ring 53 is rotatably connected to the outer wall of the support ring 52. A sliding seat 51 is fixedly connected to the top of the mounting housing 406. Two movable plates 54 are threadedly connected to the outer wall of the support ring 52. A flexible clamping mechanism 6 is provided on the top of each of the two movable plates 54. The flexible clamping mechanism 6 includes a fixed plate 601. A second sleeve 602 is fixedly connected to the outer surface of the fixed plate 601. A spring 603 is fixedly installed inside the second sleeve 602. A clamping post 604 is fixedly connected to one end of the spring 603. A limit plate 605 is slidably connected to the outer wall of the clamping post 604. A second motor 7 is located inside the first sleeve 2. The outer surfaces of the two fixed rings 408 are fixedly connected to the bottom of the mounting housing 406. The bottom of the fixed plate 601 is fixedly connected to the top of the movable plates 54. The bottoms of the two movable plates 54 are slidably connected to the outer wall of the sliding seat 51.

[0028] The overall effect of Embodiment 2 is that it further optimizes the clamping and positioning function of the satellite antenna. The first motor 5 drives the support ring 52 to rotate, enabling the fixed ring 53 and the connected movable plate 54 to rotate in the circumferential direction, providing flexibility for clamping the satellite antenna in different positions. The threaded connection design between the support ring 52 and the movable plate 54 allows the operator to precisely adjust the position of the movable plate 54 on the support ring 52 by controlling the forward and reverse rotation of the first motor 5, thereby adapting to the clamping requirements of satellite antennas of different sizes. The design of the flexible clamping mechanism 6 is also a major highlight. The spring 603 in the second sleeve 602 on the fixed plate 601 provides the clamping column with The flexible clamping capability of spring 603 allows for automatic adjustment of the clamping force according to the antenna's shape when clamping the satellite antenna. This ensures the antenna is securely clamped while preventing damage due to excessive clamping force. The limiting plate 605 limits the sliding of the clamping post 604, ensuring the stability and accuracy of the clamping process. The sliding connection between the two moving plates 54 and the sliding seat 51 further enhances the flexibility and stability of the entire clamping mechanism when adjusting its position. In summary, through these ingenious designs, Embodiment 2 achieves precise and flexible clamping of the satellite antenna, greatly improving the positioning accuracy and safety during the satellite antenna assembly process and effectively ensuring assembly quality.

[0029] Working Principle: When using the precision positioning fixture for satellite antenna assembly, first fix the fixture mounting base 1 on a suitable workbench. If it is necessary to adjust the overall angle of the satellite antenna, start the second motor 7. The output end of the second motor 7 drives the semi-circular slide rail 401 to rotate around the rotating ring 3. At this time, the operator can observe the angle measuring scale 402 on the semi-circular slide rail 401. When the approximate required angle is reached, stop the second motor 7. If more precise angle adjustments are needed, rotate the adjustment knob 409. The adjustment knob 409 drives the worm gear 407 to rotate, and the worm gear 407 drives the semi-circular gear ring 404 to rotate, thereby causing the mounting platform 403 and its connected components to change angles, achieving precise angle positioning. After completing the angle positioning, The satellite antenna is placed between the flexible clamping mechanisms 6. The first motor 5 is started, which drives the support ring 52 to rotate, causing the moving plate 54 and the flexible clamping mechanism 6 to rotate to the appropriate position. Then, by rotating the first motor 5 in both directions, the position of the moving plate 54 is adjusted using the threaded connection between the support ring 52 and the moving plate 54, so that the flexible clamping mechanism 6 is close to the satellite antenna. At this time, the clamping column 604, under the action of the spring 603, fits against the surface of the satellite antenna and automatically adjusts the clamping force according to the shape of the antenna, firmly clamping the satellite antenna. Throughout the assembly process, all components of the fixture work together to ensure that the satellite antenna is always in a precise positioning state, facilitating the operator's assembly work until the satellite antenna assembly task is completed.

[0030] The wiring diagrams of the first motor 5 and the second motor 7 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring arrangement of the first motor 5 and the second motor 7 will not be explained in detail.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
