Description

Technical Field

[0001] This utility model belongs to the field of sealing component screening technology, specifically relating to a screening and feeding device for aerospace sealing components. Background Technology

[0002] Aerospace seals are critical components in the core parts of spacecraft used to prevent leakage of internal critical media (such as fuel and coolant) and to block the intrusion of external extreme environments (such as vacuum, radiation, and high and low temperatures). They need to maintain sealing performance for a long time under harsh conditions such as extreme temperature, strong corrosion, and high vibration. Their reliability is directly related to the success or failure of aerospace missions. Common types include static O-rings and dynamic lip seals, which are mostly made of materials such as fluororubber and metal alloys that are resistant to extreme environments.

[0003] In the production of aerospace sealing components, the quality of the seals is directly related to the operational safety and reliability of spacecraft. Since the production of aerospace sealing components is mostly a batch operation, the produced seals are often piled up together and must be screened and separated.

[0004] However, the traditional manual screening method is not only inefficient and difficult to meet the stringent production cycle requirements of the aerospace industry, but also the randomness and fatigue of manual operation make it impossible to work for a long time, which further reduces the production efficiency of seals.

This adjustment assembly, by rotating the bolt and utilizing the engagement of the threaded hole, allows the bolt to move up and down, easily driving the bearing and barrier bar to rise and fall. This precisely changes the gap between the outlet and the barrier bar, enabling the device to quickly adapt to the screening requirements of seals of different sizes. Operators do not need to replace equipment parts; simple adjustments are all that is required to complete the screening of seals of different specifications, greatly improving the versatility and flexibility of the equipment.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figure 1-4This utility model provides a screening and feeding device for aerospace sealing components, including a support housing 1. A rotary motor 2 is fixedly installed inside the support housing 1. The transmission end of the rotary motor 2 passes through the top of the support housing 1 and is fixedly installed on a support platform 3. A screening assembly is provided at the upper part of the front end of the support housing 1. The screening assembly includes an installation bar 301, a support column 302, a barrier bar 303, a collecting ring 304, an outlet 305, a barrier block 306, and a discharge bar 307. The installation bar 301 is fixedly installed at the upper part of the front end of the support housing 1. The support column 302 is fixedly installed at the lower end of the installation bar 301. The barrier bar 303 is fixedly connected to the side surface of the support column 302. The collecting ring 304 is fixedly connected to the left side of the barrier bar 303. The outlet 305 is opened at the lower end of the barrier bar 303 away from the support column 302. The barrier block 306 is movably installed on the upper surface of the outlet 305. The discharge bar 307 is fixedly connected to the right side of the barrier bar 303 and located behind the outlet 305. The support housing 1 is used to house and fix the rotary motor 2, providing a stable support structure for the entire device. The rotary motor 2 drives the support platform 3 to rotate clockwise, which in turn moves the seals 7 placed on it, realizing the automatic feeding of the seals 7. In the screening assembly, the mounting strip 301 and the support column 302 constitute the installation base of the screening assembly, ensuring the stable installation of components such as the barrier bar 303. The barrier bar 303, together with the barrier block 306 and the outlet 305, can separate and screen the accumulated seals 7. Individual seals 7 can be discharged from the outlet 305, and then discharged to the next step by the discharge bar 307 through the rotation of the support platform 3.

[0019] Specifically, such as Figure 1 and Figure 4 As shown, an adjustment assembly 4 is provided on the top of the barrier bar 303. The adjustment assembly 4 includes an auxiliary groove 401, a helical spring 402, a threaded hole 403, a bolt 404, and a bearing 405. The auxiliary groove 401 is opened on the top of the barrier bar 303, the threaded hole 403 is opened on the lower surface of the auxiliary groove 401, the helical spring 402 is fixedly connected to the outside of the threaded hole 403 and located on the lower surface of the auxiliary groove 401, the bolt 404 is threadedly connected to the inside of the threaded hole 403, and the bearing 405 is fixedly sleeved on the side surface of the lower end of the bolt 404. The auxiliary groove 401 provides space for the installation of the helical spring 402. The threaded hole 403 cooperates with the bolt 404. By rotating the bolt 404, the height of the blocking block 306 can be adjusted, thereby changing the gap between the outlet 305 and the blocking rod 303. The helical spring 402 can increase the friction between the threaded hole 403 and the bolt 404, thereby improving the stability of the blocking block 306 and ensuring the stability of the screening size. The bearing 405 reduces the friction between the bolt 404 and the blocking block 306, making the adjustment operation easier and more convenient.

[0020] Specifically, such as Figure 2 and Figure 3As shown, a guide block 5 is fixedly connected to the left side of the barrier bar 303 and inside the collecting ring 304. A collecting block 6 is fixedly connected to the end of the collecting ring 304 away from the barrier bar 303. Several sealing elements 7 are placed on the top of the support platform 3. The guide block 5 is located inside the collecting ring 304, and its smooth inclined surface design can guide the unscreened sealing elements 7 to slide smoothly into the collecting ring 304. The cross-section of the collecting block 6 is triangular, which can effectively collect the sealing elements 7 near the outside of the support platform 3 and prevent them from slipping. The support platform 3 is used to support the sealing elements 7 and, driven by the rotary motor 2, moves the sealing elements 7 to the screening component for screening.

[0021] A heat dissipation groove 8 is provided on the right side of the support housing 1. Strip grids 9 are fixedly connected in a linear array inside the heat dissipation groove 8. The strip grids 9 can prevent foreign objects from entering the support housing 1 and protect internal components such as the rotating motor 2. They can also ensure that the heat generated by the rotating motor 2 is effectively dissipated through the heat dissipation groove 8, avoiding performance degradation or damage to the motor due to overheating, ensuring that the device can operate stably for a long time and extending the service life of the device.

[0022] Specifically, such as Figure 4 As shown, the upper end of the helical spring 402 is rotatably connected to the bolt 404, and the outer ring side surface of the bearing 405 is fixedly connected to the blocking block 306.

[0023] The side of the guide block 5 away from the barrier bar 303 is inclined and has a smooth surface, and the cross-section of the collection block 6 is triangular.

[0024] Working principle and usage process of this utility model: The staff first places several sealing components 7 on top of the support platform 3 and starts the rotary motor 2. Then the rotary motor 2 drives the support platform 3 to rotate clockwise, causing the sealing components 7 to move towards the screening component at the front end of the support housing 1. When the sealing components 7 rotate with the support platform 3 to the left of the barrier bar 303, the stacked sealing components 7 are blocked by the barrier bar 303. At this time, the gap formed by the outlet 305 and the barrier block 306 only allows a single sealing component 7 to pass through. The stacked sealing components 7 will be intercepted and separated by the barrier block 306. After screening, the single sealing component 7 will continue to rotate with the support platform 3 and be guided by the discharge bar 307 to be discharged to the next process.

[0025] If the operator needs to adjust the size of the outlet 305 opening, the bolt 404 of the adjusting component 4 can be rotated, and the bolt 404 can be moved up and down by the engagement of the threaded hole 403. This will drive the bearing 405 and the barrier block 306 to rise and fall, thereby changing the gap between the outlet 305 and the barrier bar 303, thus improving the adaptability to seals 7 of different heights.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
