Description

Technical Field

[0001] This utility model belongs to the field of transfer devices, specifically relating to a device for the turnover and storage of ring-shaped aerospace parts. Background Technology

[0002] Ring-shaped aerospace components are important parts in the aerospace manufacturing field. They generally need to be transferred from the storage area to the assembly area. During the transfer process, it is necessary to ensure the stability of the components to prevent them from falling. Furthermore, during assembly, they also need to be able to be placed on other components.

[0003] In existing technologies, ring-shaped aerospace components are generally transferred by means of transport, that is, by using a robotic arm to support the ring-shaped aerospace components. Although this transfer method can increase the stability during the transfer process to a certain extent, the supporting part will become an obstacle when the ring-shaped component is put on other assemblies. Therefore, other devices are needed to lift the ring-shaped component, which is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to provide a device that can stably transfer and place disc-shaped aerospace components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a transfer device for a ring-shaped aerospace component, including a ring-shaped central reference plate. Several booms are connected to the central reference plate, and each boom has a positioning seat connected to its free end. The ring-shaped aerospace component is clamped by the positioning seats. The positioning seats include clamps with horizontal through holes. Clamps pass through the horizontal through holes and have elastic telescopic structures. The inner ends of the clamps contact the circumferential surface of the ring-shaped aerospace component. An auxiliary plate is provided on the clamp and is hinged to the clamp. When the auxiliary plate is in a horizontal state, it supports the ring-shaped aerospace component. During the process of the auxiliary plate flipping from a horizontal state to a vertical state, it applies a thrust to the outer ends of the clamps.

[0006] Furthermore, the clamp is provided with vertical baffles located on both sides of the horizontal through-hole, and a support arm is axially connected between the two vertical baffles, with the lower end of the support arm fixedly connected to the auxiliary plate.

[0007] Furthermore, the auxiliary plate includes a straight support portion and a top clamp portion. The top clamp portion is connected to the end of the straight support portion, the support arm is fixedly connected to the straight support portion, and the top clamp portion is in contact with the outer end of the clamp arm.

[0008] Furthermore, the top clamp is an arc-shaped curved plate, and the outer end of the clamp arm abuts against the inner arc-shaped side of the arc-shaped curved plate.

[0009] Furthermore, a radially extending channel is provided on the central reference plate, extending from the circumference of the central reference plate to the center, and the boom is connected to the channel.

[0010] Furthermore, the boom includes a horizontal insertion boom and a vertical boom. The horizontal insertion boom is inserted through a channel, and the vertical boom is vertically connected to the horizontal insertion boom. When the horizontal insertion boom moves horizontally within the channel, it drives the vertical boom to move radially along the central reference plate.

[0011] Furthermore, a control panel is installed on the central reference plate. When the control panel rotates, it drives the boom to move along the radial direction of the central reference plate.

[0012] Furthermore, the control panel is circular, with several arc-shaped openings on it. The number of arc-shaped openings is the same as the number of booms. Slide rods are installed on the booms and connected to the arc-shaped openings.

[0013] Furthermore, the distance from one end of the arc-shaped opening to the center of the control panel is greater than the distance from the other end to the center of the control panel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: when transferring the ring-shaped aviation parts, the parts are clamped by the clamping arms, and at this time the auxiliary plate supports the parts to ensure that the parts will not fall off during the transfer process;

[0015] When it needs to be assembled with other components, the auxiliary plate is flipped from a horizontal to a vertical position. At this time, the auxiliary plate will not affect the assembly of the components. In the process of flipping the auxiliary plate from a horizontal to a vertical position, the auxiliary plate can apply a pushing force to the clamping arm, increase the clamping force of the clamping arm on the component, and prevent the component from falling off accidentally.

It should be understood that the preferred embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model.

In the embodiments, the components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0025] See Figures 1 to 6 As shown, a transfer device for a ring-shaped aerospace component includes a ring-shaped central reference plate 1. Several booms are connected to the central reference plate 1, and a main support arm 2 is positioned between adjacent booms. The main support arm 2 extends radially along the central reference plate 1, and its outer end can be fixed to a movable lifting mechanism, such as the forklift arm of a forklift. The forklift arm can drive the central reference plate 1 to move vertically. Each boom's free end is connected to a positioning seat 3. The ring-shaped aerospace component is clamped by several positioning seats 3, allowing for transfer. The positioning seat 3 includes a clamping base 4 with a horizontal through-hole through which a clamping arm 5 passes. The clamping arm 5 clamps the ring-shaped aerospace component. During clamping, the inner end of the clamping arm 5 contacts the circumferential surface of the ring-shaped aerospace component, thus moving and placing the component.

[0026] During the movement of the ring-shaped aerospace component, the clamping arm 5 has an elastic telescopic structure. For example, the clamping arm 5 consists of two parts: a main arm 6 and an auxiliary arm 7. The main arm 6 is located in a horizontal through-hole. A blind channel 8 starting from the end is provided on the main arm 6. One end of the auxiliary arm 7 is inserted into the blind channel, and a pad 9 is fixed to the other end of the auxiliary arm 7. A spring 10 that generates a restoring force after compression is provided in the blind channel 8. At this time, the auxiliary arm 7 can move horizontally in the blind channel. When the auxiliary arm 7 moves towards the main arm 6, the compression and restoring spring 10 can be compressed. At this time, the end of the auxiliary arm 7 that is connected to the pad is the inner end of the clamping arm, and the end of the main arm 6 that is away from the auxiliary arm 7 is the outer end of the clamping arm.

[0027] Meanwhile, an auxiliary plate 11 is provided on the clamp 4. The auxiliary plate 11 is hinged to the clamp 4. The auxiliary plate 11 can be reversed after being controlled. When the auxiliary plate 11 is in a horizontal state, the auxiliary plate 11 is located below the ring-shaped aviation component. At this time, the auxiliary plate 11 supports the ring-shaped aviation component. During the process of the auxiliary plate 11 flipping from the horizontal state to the vertical state, the auxiliary plate 11 applies a thrust to the outer end of the clamping arm 5, causing the main arm 6 to move towards the ring-shaped aviation component, increasing the clamping force on the ring-shaped aviation component.

[0028] When clamping a ring-shaped aerospace component, it is necessary to control the movement of the clamping seat 4 toward the ring-shaped aerospace component. This process is achieved by controlling the movement of the boom. Specifically, a radially extending channel 12 is provided on the central reference plate 1. The channel 12 extends from the circumference of the central reference plate 1 toward the center. The boom is connected to the channel 12 and includes a horizontal insertion arm 13 and a vertical arm 14. The horizontal insertion arm 13 is inserted into the channel 12, and the vertical arm 14 is vertically connected to the horizontal insertion arm 13. When the horizontal insertion arm 13 moves within the channel 12, it drives the vertical arm 14 to move along the radial direction of the central reference plate 1. At this time, the clamping seat 4 also moves along the radial direction of the central reference plate 1. A limit groove 15 is provided on the inner wall of the horizontal through-hole, and a limit protrusion 16 is provided on the main boom 6. The limit protrusion 16 is located at the limit Before clamping the disc-shaped aerospace component, the limiting protrusion 16 is located at the end of the limiting groove 15 away from the auxiliary arm 7. When the auxiliary plate 11 flips to the vertical position, the auxiliary plate 11 contacts the outer end of the clamping arm 5 and applies a pushing force. At this time, the main arm 6 on the clamping arm 5 will move towards the disc-shaped aerospace component, causing the spring 10 to be further compressed. This increases the clamping force on the disc-shaped aerospace component, and the auxiliary plate 11 no longer supports the disc-shaped aerospace component. When the disc-shaped aerospace component is assembled with other accessories, the bottom surface of the disc-shaped aerospace component can directly contact other accessories. Then, by controlling the clamping seat to move towards the disc-shaped aerospace component through the boom, the disc-shaped aerospace component can be no longer clamped.

[0029] The clamping seat 4 is provided with vertical baffles 17 located on both sides of the horizontal through hole. A support arm 18 is axially connected between the two vertical baffles 17. The lower end of the support arm 18 is fixedly connected to the auxiliary plate 11. The auxiliary plate 11 includes a straight support part 19 and a top clamping part 20. The top clamping part 20 is an arc-shaped curved plate. The inner arc-shaped side of the arc-shaped curved plate abuts against the outer end of the clamping arm 5. The top clamping part 20 is connected to the end of the straight support part 19. The support arm 18 is fixedly connected to the straight support part 19. When the straight support part 19 of the auxiliary plate 11 is in a horizontal state, the inner arc edge of the top clamping part 20 contacts the outer end of the clamping arm 5. When the auxiliary plate 11 is flipped to the vertical state of the support part, the top clamping part 20 approaches the clamping seat 4 and applies a pushing force to the clamping arm 5.

[0030] When the auxiliary plate 11 is flipped, a push rod 21 can be set on the bottom surface of the clamp 4. This push rod 21 can be an electric push rod or a pneumatic push rod. The push rod 21 and the bottom surface of the clamp 4 form an angle with a fixed angle value. A flat sleeve 22 is shafted at the output end of the push rod 21. The flat sleeve 22 is sleeved on the straight support part 19 of the auxiliary plate 11. When the push rod 21 is extended or shortened, the auxiliary plate 11 can be flipped.

[0031] See Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, when the clamp 4 is moved by controlling the boom, a control panel 23 needs to be installed on the central reference plate 1. At this time, an annular groove 24 is installed on the central reference plate 1, and the annular groove 24 is coaxially arranged with the central reference plate 1. A sliding groove 25 is installed on the bottom surface of the annular groove 24, and the sliding groove 25 is connected to the insertion channel 12. The sliding groove 25 also extends along the radial direction of the central reference plate 1, but the two are not located on the same straight line. At this time, the horizontal height of the sliding groove 25 is greater than the horizontal height of the insertion channel. A sliding rod 26 is installed on the flat insertion arm 13. After the sliding rod 26 passes through the sliding groove 25, its upper end is exposed in the annular groove 24. The control panel 23 is installed in the annular groove. Inside 24, the control panel 23 is circular, and several arc-shaped openings 27 are provided on the control panel 23. The number of arc-shaped openings 27 is the same as the number of booms. The upper end of the slide rod 26 is located inside the arc-shaped opening 27. Alternatively, an anti-detachment cap can be installed on the upper end of the slide rod 26. The anti-detachment cap is located inside the arc-shaped opening and has an anti-detachment groove. In this case, the anti-detachment cap and the arc-shaped opening are connected. The distance from one end of the arc-shaped opening 27 to the center of the control panel is a cm, and the distance from the other end to the center of the control panel is b cm. Here, a > b. In this way, when the control panel 23 rotates, it can drive the boom to move along the radial direction of the central reference plate 1, thereby driving the clamp 4 to move.

[0032] When the control disk 23 is rotated, it can be controlled by a drive motor. For example, the control disk 23 has teeth on its circumference. The teeth are located above the annular groove 24. Then, a drive motor is installed on the main support arm 2. The gear disk on the output shaft of the drive motor is connected to the control disk by a chain 28. When the drive motor works, it can drive the control disk 23 to rotate, thereby adjusting the position of the clamp 4.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
