Description

Technical Field

[0001] This disclosure belongs to the field of flip tooling technology, and specifically relates to a flip tooling for satellite antennas. Background Technology

[0002] A flipping fixture is a special tool or device used to assist in flipping, rotating or positioning workpieces. By using a flipping fixture, operators can quickly adjust the posture of the workpiece, improve work efficiency and ensure work safety.

[0003] Currently, the flipping fixtures for satellite antennas in the industry are simple and generally do not have speed reducers. This can lead to situations such as acceleration, swinging, falling off, collision, and damage to the antenna products during the flipping process, and workers cannot get off the equipment. Although some flipping fixtures are equipped with speed reducers, there are still problems such as unreasonable selection of reduction ratio, unstable or even failed self-locking function of the speed reducer, which can lead to situations such as falling off, collision, and damage to the antenna products. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a flipping fixture for satellite antennas.

[0005] The satellite antenna flipping fixture disclosed herein includes:

[0006] support;

[0007] A flipping mechanism is rotatably mounted on the bracket and configured to fix the satellite antenna.

[0008] A locking mechanism is disposed on the bracket and configured to prevent the flipping mechanism from flipping relative to the bracket under its own elastic force, and to overcome the elastic force under the action of a first external force so that the flipping mechanism drives the satellite antenna to flip relative to the bracket under the action of a second external force.

[0009] In one embodiment of this disclosure, the flipping mechanism includes:

[0010] Two grippers are rotatably disposed opposite each other on both sides of the bracket and configured to clamp the satellite antenna;

[0011] A handwheel is rotatably mounted on the bracket and drivenly connected to the gripper on one side. The handwheel is configured to control the rotation of the gripper under the action of a second external force.

[0012] In one embodiment of this disclosure, the handwheel is connected to the gripper on one side via a speed reduction mechanism.

[0013] In one embodiment of this disclosure, the reduction mechanism is a worm gear reducer, comprising:

[0014] The housing is fixedly mounted on the bracket;

[0015] A worm gear, which is rotatably disposed within the housing and fixedly connected to the handwheel;

[0016] A worm gear is rotatably disposed within the housing and meshes with the worm. The worm gear is fixedly connected to the gripper on one side via an output shaft.

[0017] In one embodiment of this disclosure, the locking mechanism includes:

[0018] The positioning disk is fixedly connected to the gripper on the other side, and the edge of the positioning disk is provided with a plurality of positioning grooves at intervals along the circumferential direction, and the positioning grooves extend radially.

[0019] A housing, which is fixedly mounted on the bracket;

[0020] A slide rod is movably disposed within the housing, with its end extending out of the housing. A return spring is pre-pressed between the slide rod and the housing.

[0021] The handle has an end remote from the handheld end that is hinged to the housing via a first hinge point, and the slide bar has an end remote from the positioning plate that is hinged to the handle via a second hinge point, the second hinge point being located between the first hinge point and the handheld end;

[0022] The handle is configured to pull the slide bar under the action of a first external force, overcoming the elastic force of the return spring, and move relative to the positioning plate to disengage from the positioning slot.

[0023] In one embodiment of this disclosure, a roller is rotatably provided at the end of the slide bar, and the roller is inserted into the positioning groove of the positioning disk under the elastic force of the return spring.

[0024] In one embodiment of this disclosure, a plurality of the positioning grooves are evenly distributed along the circumferential direction of the positioning disk.

[0025] In one embodiment of this disclosure, a shock absorber is fixedly disposed in each of the positioning slots.

[0026] In one embodiment of this disclosure, the flipping mechanism further includes:

[0027] Flip rack;

[0028] A sliding plate, which is slidably mounted on the tilting frame in a manner that extends along the rotation axis of the gripper under the action of an external force;

[0029] A locking assembly is disposed on the sliding plate and configured to secure the satellite antenna on the sliding plate.

[0030] In one embodiment of this disclosure, the flipping frame is configured to slide relative to the two grippers along a sliding direction perpendicular to the sliding plate.

[0048] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0049] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0050] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0051] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0052] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0053] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0054] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0055] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0056] Currently, the flipping fixtures for satellite antennas in the industry are simple and generally do not have speed reducers. This can lead to situations such as acceleration, swinging, falling off, collision, and damage to the antenna products during the flipping process, and workers cannot get off the equipment. Although some flipping fixtures are equipped with speed reducers, there are still problems such as unreasonable selection of reduction ratio, unstable or even failed self-locking function of the speed reducer, which can lead to situations such as falling off, collision, and damage to the antenna products.

[0057] To address this, the present disclosure provides a satellite antenna flipping fixture, including a bracket, a flipping mechanism, and a locking mechanism. The flipping mechanism is rotatably mounted on the bracket and configured to fix the satellite antenna. The locking mechanism is mounted on the bracket and configured to prevent the flipping mechanism from flipping relative to the bracket under its own elastic force, and under the action of a first external force, overcome the elastic force to allow the flipping mechanism to drive the satellite antenna to flip relative to the bracket under the action of a second external force.

[0058] In detail, when using the flipping fixture of this disclosure, the satellite antenna is first fixed to the flipping mechanism. Without external force, the satellite antenna is locked by the elastic force of the locking mechanism, preventing the flipping mechanism from shaking or becoming unstable due to gravity or other factors. At this point, technicians can perform operations on the satellite antenna. Then, technicians can apply a first external force to the locking mechanism, switching it from the locked position to the released position. Next, technicians can apply a second external force to the flipping mechanism, causing it to flip the satellite antenna relative to the support under the second external force. Once the preset position is reached, technicians can stop applying the first and second external forces, and the locking mechanism, under its own elastic force, will lock the flipping mechanism and satellite antenna again. Clearly, the flipping fixture of this disclosure is convenient and simple to operate.

[0059] Thus, the flipping fixture disclosed herein adopts a compact and stable structural design, is simple and convenient to operate, and has a fast-responding locking mechanism. Technicians can efficiently and promptly lock the flipping mechanism and satellite antenna. Furthermore, when technicians leave the equipment, the flipping fixture can maintain a stable posture, effectively preventing the satellite antenna from accidentally falling off, colliding, or being damaged, thus ensuring the safety and integrity of the satellite antenna.

[0060] For ease of understanding, please refer to the following: Figures 1 to 10 The present disclosure will describe in detail the specific structure and working principle of the satellite antenna flipping fixture provided in this embodiment.

[0061] In one embodiment, the satellite antenna flipping fixture of this disclosure includes a bracket 1, a flipping mechanism 2, and a locking mechanism 3. The flipping mechanism 2 is rotatably mounted on the bracket 1 and configured to fix the satellite antenna. The locking mechanism 3 is mounted on the bracket 1 and configured to prevent the flipping mechanism 2 from flipping relative to the bracket 1 under its own elastic force, and to overcome the elastic force under a first external force, causing the flipping mechanism 2 to drive the satellite antenna to flip relative to the bracket 1 under a second external force.

[0062] Combination Figure 1 The flipping mechanism 2 of this disclosed flipping fixture is mounted on a support 1. The satellite antenna to be flipped is fixed to the flipping mechanism 2. Simultaneously, a locking mechanism 3 is also mounted on the support 1 and, under its own elastic force, locks the flipping mechanism 2, thereby preventing the flipping mechanism 2 and the satellite antenna from flipping relative to the support 1. Alternatively, a technician can apply a first external force to the locking mechanism 3 to overcome the elastic force and switch from a locked position to a released position. Then, the technician can apply a second external force to the flipping mechanism 2, causing it to flip the satellite antenna. When the satellite antenna flips to a preset position, the external force is stopped, and the locking mechanism 3 will lock the flipping mechanism 2 again. In this way, the locking mechanism 3 of this disclosure can efficiently and promptly lock the flipping mechanism 2 securely.

[0063] Further, see Figure 2 The support 1 of this disclosure has two supporting ribs 13 connected to its bottom, one in the middle and the other at the edge, to increase the stability of the support 1. Optionally, the supporting rib 13 at the bottom of the support 1 can be a single rib supporting the middle or multiple ribs supporting the bottom. Furthermore, the multiple supporting ribs 13 can be evenly distributed to further increase the stability of the support 1. In addition, the support 1 of this disclosure has two supporting columns 14 on each side, constructed in a triangular shape, to improve the stability of the support 1. Furthermore, the supporting columns 14 on both sides can also be two or more parallel, which is not limited in this disclosure.

[0064] In addition, triangular stabilizers can be installed at the connection points of bracket 1 to improve the stability and rigidity of the structure. This can prevent localized stress concentration and extend the service life of bracket 1.

[0065] See Figure 1 and Figure 3 In one embodiment of this disclosure, the flipping mechanism 2 includes two grippers 21 and a handwheel 22. The two grippers 21 are rotatably disposed opposite each other on both sides of the bracket 1 and are configured to clamp the satellite antenna. The handwheel 22 is rotatably disposed on the bracket 1 and is connected to the gripper 21 on one side. The handwheel 22 is configured to control the gripper 21 to rotate under the action of a second external force.

[0066] In detail, mounting plates are provided on both sides of bracket 1, such as... Figure 1 As shown in the embodiment, a first mounting plate 11 is fixedly disposed on the left side of the flipping fixture, and a second mounting plate 12 is fixedly disposed on the right side. The fixed ends of the first mounting plate 11 and the second mounting plate 12 are fixed to the bracket 1 by bolts. Optionally, they can also be fixed by snap-fit, welding or other methods. This disclosure does not impose any restrictions on these methods.

[0067] Furthermore, both the first mounting plate 11 and the second mounting plate 12 have a mating hole at the end away from the fixed end. Two bearings with seats are fixed through the mating hole. Each bearing with a seat has a rotating shaft 211. A gripper 21 is fixed on the rotating shaft 211. In this way, after the gripper 21 of the flipping fixture of this disclosure clamps the satellite antenna, it can drive the satellite antenna to flip relative to the bracket 1.

[0068] Furthermore, the handwheel 22 of the flipping mechanism 2 of this disclosure is mounted on the first mounting plate 11 on the left side of the bracket 1 and is connected to the rotating shaft 211 on the same side, which passes through the bearing seat. This drives the left gripper 21 to rotate and supports the rotating shaft 211 through the bearing seat, reducing friction. Since both grippers 21 clamp the satellite antenna together, and the right gripper 21 is also rotatably mounted on the second mounting plate 12, the left gripper 21 drives the right gripper 21 to rotate through the clamped satellite antenna. Thus, under the action of a second external force, the handwheel 22 can flip the satellite antenna relative to the bracket 1.

[0069] At the same time, combined Figure 6 and Figure 8 The two grippers 21 of the flipping fixture disclosed herein are also provided with fasteners 27. After the grippers 21 clamp the satellite antenna, the fasteners 27 are adjusted to further clamp the item. By setting adjustable fasteners, the flipping fixture disclosed herein can adapt to satellite antennas of different shapes.

[0070] In one embodiment of this disclosure, the handwheel 22 is connected to the gripper 21 on one side via a reduction mechanism 23.

[0071] In detail, the rotational motion of the handwheel 22 is transmitted to the gripper 21 via the reduction mechanism 23. This transmission method ensures that the operator can easily and precisely control the gripper 21 even under high load conditions. The reduction mechanism 23 consists of a series of gears or other mechanical components, and its main function is to reduce the rotational speed of the handwheel 22 and increase the output torque. This not only makes operation less strenuous but also provides higher control precision. Common reduction mechanisms 23 include worm gears, planetary gears, etc. Thus, under the action of a second external force, the handwheel 22 is connected to the gripper 21 on one side via the reduction mechanism 23, enabling the gripper 21 to rotate smoothly and precisely when the handwheel 22 is rotated.

[0072] Those skilled in the art can select a suitable deceleration mechanism 23 according to the actual situation, and no limitation is made in this disclosure.

[0073] See Figure 1 and Figure 3 In one embodiment of this disclosure, the reduction mechanism 23 is a worm gear reducer, including a housing 231, a worm 232, and a worm wheel 233. The housing 231 is fixedly mounted on the bracket 1; the worm 232 is rotatably mounted within the housing 231 and fixedly connected to a handwheel 22; the worm wheel 233 is rotatably mounted within the housing 231 and meshes with the worm 232, and the worm wheel 233 is fixedly connected to a gripper 21 on one side via an output shaft.

[0074] In detail, the housing 231 of the reduction mechanism 23 of this disclosure is fixed to the first mounting plate 11 on one side of the handwheel 22 by a reduction mechanism mounting seat, and a worm gear 233 and a worm 232 meshing with each other are provided inside the housing 231. Combined with... Figure 4 and Figure 5 The handwheel 22 of this disclosure is connected to the worm gear 232 via a coupling, enabling the worm gear 232 to be driven smoothly and precisely when the handwheel 22 is rotated. A coupling is a mechanical component used to connect two rotating shafts to transmit torque and rotational motion. It not only effectively transmits power but also compensates for minor misalignment between the two shafts, reducing vibration and noise.

[0075] Combination Figure 6 The worm gear 233 is centrally connected to an output shaft, which is fixedly connected to a rotating shaft 211 on the left side that passes through a bearing with a seat, thereby controlling the gripper 21 on the left side. Furthermore, since the reduction mechanism 23 and its mounting base are fixed to the handwheel 22 side on the first mounting plate 11, the bearing with a seat on the first mounting plate 11 is fixed to the side near the gripper 21, and an interference fit is provided with the mating hole of the first mounting plate 11.

[0076] Optionally, see Figure 1In one embodiment, a dead stop 212 is fixedly provided on the left side of the rotating shaft 211 near the end of the gripper 21. Correspondingly, a pair of inverted "L"-shaped stop members 15 are fixed on the left side of the bracket 1, and the two stop members 15 are symmetrically arranged along the rotation axis of the gripper 21, so as to cooperate with the dead stop 212 at the end of the rotating shaft 211. In this way, the maximum rotation angle of the flipping mechanism 2 of this disclosure is further limited, the stability of the flipping fixture is increased, and the satellite antenna damage caused by excessive rotation is avoided.

[0077] See Figure 1 and Figure 7 In one embodiment of this disclosure, the locking mechanism 3 includes a positioning disk 31, a housing 32, a slide bar 33, and a handle 35. The positioning disk 31 is fixedly connected to the gripper 21 on the other side, and a plurality of positioning grooves 311 are sequentially spaced along the circumferential direction on the edge of the positioning disk 31, with the positioning grooves 311 extending radially. The housing 32 is fixedly mounted on the bracket 1. The slide bar 33 is movably mounted inside the housing 32, and the end of the slide bar 33 extends out of the housing 32. A return spring 34 is pre-pressed between the slide bar 33 and the housing 32. The end of the handle 35 away from the hand-held end is hinged to the housing 32 through a first hinge point, and the end of the slide bar 33 away from the positioning disk 31 is hinged to the handle 35 through a second hinge point, the second hinge point being located between the first hinge point and the hand-held end. The handle 35 is configured to pull the slide bar 33 under the action of a first external force to overcome the elastic force of the return spring 34 and move relative to the positioning disk 31 to disengage from the positioning groove 311.

[0078] In detail, the positioning plate 31 of the locking mechanism 3 of this disclosure is located on the opposite side from the handwheel 22, thereby avoiding mutual interference between the locking mechanism 3 and the flipping mechanism 2. Figure 8 The positioning disk 31 of the locking mechanism 3 disclosed herein is fixedly connected to the rotating shaft 211 on the right side, thereby rotating coaxially with the gripper 21 fixed at the other end of the rotating shaft 211. At the same time, the edge of the positioning disk 31 is provided with a positioning groove 311 extending radially. The number of positioning grooves 311 can be determined by those skilled in the art according to the actual situation.

[0079] In addition, the base of the right-side mounted bearing is close to the jaw 21 and fixed on the second mounting plate 12. Its bearing portion extends from the jaw 21 in a direction away from the jaw 21 and passes through the mating hole on the second mounting plate 12. The bearing portion is axially limited by the base of the mounted bearing, so that the bearing portion is located on the right side of the mounting plate, thereby increasing the stability of the jaw 21 rotation and increasing the accommodating space between the two jaws 21.

[0080] Furthermore, the second mounting plate 12 on the right side is fixedly provided with a housing 32 at the end away from the gripper 21. The housing 32 has space for the slide rod 33 to move inside, and both ends are provided with openings so that the end of the slide rod 33 can extend out of the housing 32. In this way, one end of the slide rod 33 can extend out of the housing 32 under the action of elastic force and be inserted into the positioning groove 311 of the positioning disk 31, thereby locking the flipping mechanism 2. Alternatively, the other end of the slide rod 33 can be pulled away from the positioning disk 31 under the action of a first external force, thereby releasing the locking state of the flipping mechanism 2 of this disclosure.

[0081] At the same time, combined Figure 9 The handle 35 of the locking mechanism 3 disclosed herein is used to pull the slide bar 33 to move. The end of the handle 35 away from the hand-held end is connected to the bracket 1. Furthermore, it can be hinged to the second mounting plate 12 through the first hinge point. The end of the slide bar 33 away from the positioning plate 31 is hinged to the handle 35 through the second hinge point. The second hinge point on the handle 35 is located between the first hinge point and the hand-held end, so that the first external force acts on the handle 35, thereby driving the slide bar 33 away from the positioning groove 311, so that the flipping mechanism 2 is released from locking.

[0082] Furthermore, a return spring 34 is pre-pressed between the slide rod 33 and the housing 32. In this way, the slide rod 33 can be locked into the positioning groove 311 under the elastic force of the return spring 34 to lock the flipping mechanism 2. Then, when the handle 35 is pulled by the first external force to overcome the elastic force of the return spring 34, the end of the slide rod 33 is disengaged from the positioning groove 311 of the positioning plate 31, and the lock is released. If the handle 35 is released, the slide rod 33 can be locked into the positioning groove 311 again under the action of the return spring 34.

[0083] See Figure 9 and Figure 10 In one embodiment of this disclosure, a roller 331 is rotatably provided at the end of the slide bar 33. Under the elastic force of the return spring 34, the roller 331 is inserted into the positioning groove 311 of the positioning disk 31.

[0084] In detail, in its natural state, under the elastic force of the return spring 34, the roller 331 is pushed towards the positioning plate 31 and accurately inserted into the positioning groove 311 on the positioning plate 31. When the handle 35 is pulled, causing the slide bar 33 to overcome the elastic force of the return spring 34 and move, the roller 331 at the end of the slide bar 33 disengages from the current positioning groove 311, allowing the slide bar 33 to continue moving to the next positioning groove 311. In this way, the free rotation characteristic of the slide bar 33 of this disclosure, through the roller 331, reduces the frictional resistance when entering and exiting the positioning groove 311, improving the smoothness and reliability of operation.

[0085] See Figure 7In one embodiment of this disclosure, a plurality of positioning grooves 311 are evenly distributed along the circumferential direction of the positioning disk 31.

[0086] The positioning grooves 311 are evenly distributed along the circumference of the positioning disk 31, ensuring that the slide rod 33 can achieve precise positioning at multiple angles within its range of motion. One end of the slide rod 33 is rotatably equipped with a roller 331. Under the elastic force of the return spring 34, the roller 331 can accurately insert into any one of the positioning grooves 311 on the positioning disk 31. This ensures that the slide rod 33 can be precisely locked in each preset position while reducing friction during movement.

[0087] In one embodiment of this disclosure, a shock absorber 312 is fixedly disposed in each positioning groove 311.

[0088] In detail, the positioning groove 311 of the positioning disc 31 of this disclosure is fitted with a shock absorber 312 in accordance with the shape of the groove and is fixed by bolts. The shock absorber 312 is fixedly disposed in each positioning groove 311, located below and / or around the contact surface of the roller 331, to absorb the impact force generated when the roller 331 is inserted and to reduce vibration during operation. The shock absorber 312 can absorb impact and vibration, reduce hard contact between the roller 331 and the positioning groove 311, thereby extending the service life of the locking mechanism 3. The shock absorber 312 is usually made of elastic material, such as rubber, polyurethane or spring steel, and has good cushioning performance.

[0089] In one embodiment of this disclosure, the flipping mechanism 2 further includes a flipping frame 24, a sliding plate 25, and a locking assembly 26, wherein the sliding plate 25 is slidably disposed on the flipping frame 24 in a manner extending along the rotation axis of the gripper 21 under the action of an external force; the locking assembly 26 is disposed on the sliding plate 25 and is configured to fix the satellite antenna on the sliding plate 25.

[0090] In detail, the flipping frame 24 of the flipping mechanism 2 of this disclosure is a rectangular frame, and the sliding plate 25 on the flipping frame 24 fixes the satellite antenna by the locking assembly 26. The locking assembly 26 includes a fixed base and a locking member. The fixed base is fixedly mounted on the sliding plate 25, and the locking member is rotatably mounted on the fixed base. A tension spring is pre-pressed between the locking member and the fixed base.

[0091] When fixing the satellite antenna, the operator applies external force to overcome the elastic force of the tension spring, causing the locking component to rotate relative to the fixed base to a preset angle. Then, the base of the satellite antenna is placed on the opened angle, and the external force is stopped. The locking component is reset under the action of the tension spring, and the satellite antenna is locked onto the sliding plate 25. Finally, bolts are used on the locking assembly 26 to completely fix the satellite antenna relative to the sliding plate 25.

[0092] The flipping frame 24 is clamped on both sides by grippers 21. Additionally, sliding grooves are provided in the middle of the frame on both sides extending along the rotation axis of the grippers 21, allowing the edge of the sliding plate 25 of the flipping mechanism 2 to engage with the sliding grooves. Furthermore, a locking element is provided on the sliding plate 25. When the operator adjusts the sliding plate 25 to a preset position, the locking element can be adjusted to limit the displacement of the sliding plate 25, ensuring that the sliding plate 25 stably fixes the satellite antenna. This allows for dynamic adjustment of the center of gravity of the flipping fixture, ensuring good balance during the flipping process, reducing unnecessary vibration or tilting, and significantly improving the stability and safety of the system. Furthermore, it can accommodate various specifications of satellite antennas, improving the versatility of the flipping fixture. It allows the satellite antenna to move along the rotation axis, facilitating quick and accurate loading and unloading operations, and preventing collisions or friction with other components during the flipping process.

[0093] In one embodiment of this disclosure, the flipping frame 24 is configured to slide relative to the two grippers 21 in a sliding direction perpendicular to the sliding plate 25.

[0094] In detail, the flipping frame 24 of this disclosure has a groove on the clamping surface that contacts the gripper 21, and the groove extends along a direction perpendicular to the rotation axis of the gripper 21. Correspondingly, it is combined with... Figure 6 and Figure 8 Each of the two grippers 21 has symmetrical fasteners 27. Therefore, when the distance between the opposite fasteners 27 on both sides of the two grippers 21 is increased, the flipping frame 24 can slide relative to the two grippers 21 in a sliding direction perpendicular to the sliding plate 25. When the distance between the fasteners 27 on both sides of the two grippers 21 is decreased, the displacement of the flipping frame 24 in a sliding direction perpendicular to the sliding plate 25 is limited, thus fixing the flipping frame 24 relative to the two grippers 21. This facilitates quick and accurate loading and unloading of satellite antennas and prevents collisions and damage. At the same time, it adapts to satellite antennas of different sizes and shapes and optimizes the system's center of gravity distribution.

[0095] The working principle of the satellite antenna flipping fixture disclosed herein will be further explained by taking a satellite antenna flipping application scenario as an example.

[0096] First, the technicians place the antenna transport plate of the satellite antenna on the sliding plate 25 and fix it with the locking assembly 26. The antenna transport plate is a device or support structure specially designed for the safe transport of the antenna. Then, the satellite antenna is fixed to the antenna transport plate. In order to adapt to the shape of the satellite antenna, the technicians continue to adjust the position of the sliding plate 25 along the rotation axis of the gripper 21 and then lock the sliding plate 25. The position of the flipping frame 24 is adjusted along the direction perpendicular to the rotation axis of the gripper 21 and locked, thereby ensuring that there is no risk of position interference and collision during the flipping process.

[0097] Then, the technician pulls the handle 35, causing the roller 331 at the end of the slide bar 33 to separate from the positioning groove 311, releasing the locking mechanism 3, and turning the handwheel 22 to drive the satellite antenna to flip. When the satellite antenna is flipped to the designated position, the handwheel 22 is stopped, and the worm gear reduction mechanism 23 of the flipping mechanism 2 can self-lock. At the same time, the handle 35 is stopped, and the slide bar 33 is locked into the positioning groove 311 under the action of the return spring 34, further realizing the locking of the flipping mechanism 2. In this way, the double locking of the flipping fixture is achieved.

[0098] Thus, the flipping fixture disclosed herein adopts a compact and stable structural design, is simple and convenient to operate, and has a fast-responding locking mechanism 3. Technicians can efficiently and promptly lock the flipping mechanism 2 and the satellite antenna. When technicians leave the equipment, the flipping fixture can maintain a stable posture, effectively preventing the satellite antenna from accidentally falling off, colliding, or being damaged, and ensuring the safety and integrity of the satellite antenna.
