Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aerospace mechanical parts manufacturing, specifically an auxiliary positioning device. Background Technology
[0002] Aviation machinery mainly refers to various mechanical equipment used in the manufacture, maintenance, repair and modification of aircraft (including airplanes, helicopters, etc.), as well as the mechanical systems of the aircraft itself. It is the key to ensuring the normal operation and flight safety of aircraft. During production, various parts need to be processed and then assembled. In the production process of aviation machinery parts, auxiliary positioning devices play a vital role in fixing aviation machinery parts to facilitate subsequent welding and other processes.
[0003] Existing auxiliary positioning devices typically place the part on a support platform and then fix it with clamps or similar means. They can also move and rotate the part. For example, a positioning fixture for aerospace mechanical processing with authorization announcement number CN221211438U uses a similar method. However, it is not convenient to flip the parts, especially when processing large aerospace mechanical parts, such as mechanical shells. Due to the large size and weight of large parts, they generally require external hoisting facilities, which is quite troublesome. Therefore, we provide an auxiliary positioning device to solve the above problems. Utility Model Content
[0004] 1) Technical problems to be solved
[0005] This utility model proposes an auxiliary positioning device, which solves the problem that existing methods for positioning large aerospace mechanical parts generally require external hoisting facilities due to the large size and weight of the parts.
[0006] (ii) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning device, comprising a base plate and two clamping mechanisms on the base plate, a support rod fixedly connected to the upper surface of the base plate, a support plate slidably connected to the outer surface of the support rod, and a top plate fixedly connected to the upper end of the support rod; a hydraulic push rod fixedly installed on the upper surface of the base plate, the telescopic end of the hydraulic push rod being fixedly connected to the support plate; a power mechanism is provided above the top plate, a steel wire rope is provided at the lower part of the power mechanism, and a fixing mechanism is provided at the lower end of the steel wire rope.
[0008] Furthermore, the inner wall of the support plate is rotatably connected to a roller, and the inner wall of the base plate is also provided with a groove.
[0009] Furthermore, a baffle is fixedly connected to one side of the base plate, and the upper end of the baffle is fixedly connected to the top plate.
[0010] Furthermore, the fixing mechanism includes a rotating plate, the upper end of which is rotatably connected to the wire rope, and the lower end of which is detachably connected to a fixing component.
[0011] Furthermore, the power mechanism includes an electric motor, which is fixedly mounted on the upper surface of the top plate. A threaded rod is fixedly connected to the output end of the electric motor, and a sliding plate is threadedly connected to the outer surface of the threaded rod.
[0012] Furthermore, a connecting shaft is fixedly connected to the lower surface of the sliding plate, the lower surface of the connecting shaft is fixedly connected to the connecting plate, the outer surface of the connecting shaft is slidably connected to the top plate, and the lower surface of the connecting plate is fixedly connected to the wire rope.
[0013] Furthermore, a limiting block is fixedly connected to the upper surface of the top plate, and the inner wall of the limiting block is rotatably connected to the threaded rod.
[0014] (iii) Beneficial effects:
[0015] Compared with existing technologies, this auxiliary positioning device has the following advantages:
[0016] I. This auxiliary positioning device, through the use of components such as steel wire ropes and support plates, fixes one side of the part with a fixing mechanism. Controlling the downward movement of the support plate causes the part, under the influence of gravity, to move downwards on the side away from the fixing mechanism, thus rotating the part 90 degrees. Then, the power mechanism drives the upper end of the steel wire rope to move horizontally to one side, thereby moving the fixing mechanism to one side. At this point, the upper surface of the support plate contacts the lower part of the part. Simultaneously, the upward movement of the support plate causes the upper part of the part to move to one side under the action of the power mechanism and the fixing mechanism, thus rotating the part another 90 degrees. This achieves the effect of facilitating the rotation of parts, thereby solving the problem that existing methods for handling large aerospace mechanical parts, due to their large size and weight, generally require external hoisting facilities, which is quite cumbersome.
[0017] Second, this auxiliary positioning device, by setting up components such as rollers and baffles, allows the rollers to rotate freely when the lower end of the part slides against the support plate, effectively reducing the friction between the two, preventing the part from getting stuck, and ensuring a smooth flipping process. The baffle on one side of the base plate blocks the part, preventing it from detaching from the upper part of the support plate when it is lifted and flipped, ensuring operational safety. After the part is flipped into place, the two clamping mechanisms on the base plate are activated. The clamping mechanisms push the clamping plates to squeeze and fix the part from both ends, effectively preventing the part from sliding during subsequent processing and ensuring processing accuracy.

Detailed Implementation
[0024] 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.
[0025] The hydraulic push rod 5 and the electric motor 601 in this utility model are common power devices in the prior art, and this application will not elaborate on their models or internal structures.
[0026] like Figure 1-4As shown, this utility model provides a technical solution: an auxiliary positioning device, including a base plate 1 and two clamping mechanisms 10 on the base plate 1. A support rod 2 is fixedly connected to the upper surface of the base plate 1, and a support plate 3 is slidably connected to the outer surface of the support rod 2. A top plate 4 is fixedly connected to the upper end of the support rod 2. A hydraulic push rod 5 is fixedly installed on the upper surface of the base plate 1, and the telescopic end of the hydraulic push rod 5 is fixedly connected to the support plate 3. A power mechanism 6 is provided above the top plate 4, and a wire rope 7 is provided below the power mechanism 6. A fixing mechanism 8 is provided at the lower end of the wire rope 7. There are four support rods 2, which are used to fix the base plate 1 and the top plate 4 together. The hydraulic push rod 5 can drive the support plate 3 to move up or down. The support rods 2 restrict the support plate 3 to prevent the support plate 3 from shifting when moving up and down. When the part is placed on the support plate 3, one side of the part is fixed by the fixing mechanism 8. The support plate 3 is controlled to move downward, so that the part moves downward away from the fixing mechanism 8 under the action of gravity, thereby flipping the part 90 degrees. Then, the power mechanism 6 can drive the upper end of the wire rope 7 to move horizontally to one side, thereby driving the fixing mechanism 8 to move to one side. At this time, the upper surface of the support plate 3 contacts the lower part of the part. At the same time, the upward movement of the support plate 3 causes the upper part of the part to move to one side under the action of the power mechanism 6 and the fixing mechanism 8, thereby flipping the part another 90 degrees, achieving the effect of facilitating the flipping of the part. The clamping mechanism 10 consists of an electric push rod and a clamping plate, which can squeeze and fix the part at both ends to prevent the part from sliding. This is the same as the existing technology, so it will not be described in detail.
[0027] The inner wall of the support plate 3 is rotatably connected to a roller 9, and the inner wall of the base plate 1 is also provided with a groove 12. The roller 9 can rotate. When the lower end of the part slides with the support plate 3, the friction between the two can be reduced to prevent jamming. The groove 12 is used to facilitate the fixing mechanism 8 and the part to fix the fixing mechanism 8.
[0028] A baffle 11 is fixedly connected to one side of the base plate 1. The upper end of the baffle 11 is fixedly connected to the top plate 4. The baffle 11 can block the parts to prevent them from detaching from the upper part of the support plate 3 when the parts are lifted.
[0029] The fixing mechanism 8 includes a rotating plate 801. The upper end of the rotating plate 801 is rotatably connected to the wire rope 7. The lower end of the rotating plate 801 is detachably connected to a fixing member 802. The fixing member 802 is fixed to the rotating plate 801 by bolts. The fixing member 802 can be replaced according to the specific shape of the part. For example, the structure shown in the figure where the clamp and bolts fix the part can also be a hook or a screw that matches the pre-drilled hole on the part. It is mainly used to fix it to one side of the part. The rotating plate 801 can rotate at the bottom of the wire rope 7 to adapt to the change of angle between the part and the wire rope 7.
[0030] The power mechanism 6 includes an electric motor 601, which is fixedly installed on the upper surface of the top plate 4. The output end of the electric motor 601 is fixedly connected to a threaded rod 602, and a sliding plate 603 is threadedly connected to the outer surface of the threaded rod 602. The electric motor 601 is a forward and reverse motor, which can drive the threaded rod 602 to rotate, thereby driving the sliding plate 603 to move horizontally.
[0031] A connecting shaft 604 is fixedly connected to the lower surface of the sliding plate 603. The lower surface of the connecting shaft 604 is fixedly connected to the connecting plate 605. The outer surface of the connecting shaft 604 is slidably connected to the top plate 4. The lower surface of the connecting plate 605 is fixedly connected to the wire rope 7. Two grooves are provided on the top plate 4 to allow the connecting shaft 604 to slide inside. When the sliding plate 603 slides horizontally, it can drive the connecting plate 605 to slide horizontally, so as to drive the upper end of the wire rope 7 to slide horizontally.
[0032] A limiting block 606 is fixedly connected to the upper surface of the top plate 4. The inner wall of the limiting block 606 is rotatably connected to the threaded rod 602. The limiting block 606 is used to increase the firmness of the threaded rod 602 and support the end of the threaded rod 602.
[0033] Working principle: When in use, the aerospace mechanical parts are placed on the upper surface of the support plate 3. At this time, the parts can be fixed by the clamping mechanisms 10 at both ends according to the shape of the parts, so as to facilitate the positioning of the parts. When it is necessary to flip, the parts are released from the fixation, and the appropriate fixing parts 802 are installed on the lower end of the rotating plate 801. Then, the fixing parts 802 are used to firmly fix one side of the parts. The rotating plate 801 is rotatably connected to the wire rope 7. This design allows the fixing mechanism 8 to flexibly adjust the angle when fixing the parts to adapt to different shapes of the parts.
[0034] When the hydraulic push rod 5 is activated, its telescopic end drives the support plate 3 to move downward along the support rod 2. Since the support rod 2 restricts the movement direction of the support plate 3, it prevents deviation. As the support plate 3 moves downward, the part naturally droops on the side away from the fixed mechanism 8 under the action of gravity, thereby achieving a downward flip of 90 degrees. During this process, the roller 9 on the inner wall of the support plate 3 plays a key role. When the lower end of the part slides with the support plate 3, the roller 9 can rotate freely, effectively reducing the friction between the two, preventing the part from jamming, and ensuring a smooth flipping process.
[0035] When the power mechanism 6 starts working, the motor 601 on the upper surface of the top plate 4 drives the threaded rod 602 to rotate. The sliding plate 603, which is threaded to the outer surface of the threaded rod 602, moves horizontally under the action of threaded transmission. The sliding plate 603 drives the upper end of the wire rope 7 to move horizontally to one side through the connecting shaft 604 and the connecting plate 605, thereby pulling the upper part of the fixing mechanism 8 and the connected parts to move to one side. At the same time, the hydraulic push rod 5 controls the support plate 3 to move upward. The upper surface of the support plate 3 contacts the lower part of the part and provides support force. Under the synergistic action of the power mechanism 6 and the support plate 3, the part completes the second 90-degree flip, and finally achieves the 180-degree flip of the part.
[0036] During the part flipping process, the baffle 11 on one side of the base plate 1 blocks the part to prevent it from falling off the upper part of the support plate 3 when it is lifted and flipped, thus ensuring operational safety. After the part is flipped into place, the two clamping mechanisms 10 on the base plate 1 are activated. The clamping mechanisms 10 push the clamping plates to squeeze and fix the part from both ends, effectively preventing the part from sliding during subsequent processing and ensuring processing accuracy.

[0038] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model.
