Description

Technical Field

[0001] This utility model relates to the field of parts processing mechanisms, and more specifically, to a processing mechanism for aerospace fasteners. Background Technology

[0002] Aerospace fasteners are mechanical parts used to connect various components of aerospace vehicles, including bolts, nuts, rivets, and pins. These fasteners play a crucial role in the aerospace field, ensuring the integrity and safety of the aircraft structure. The cutting mechanism in aerospace fastener machining operations performs corresponding processing procedures based on the shape, size, and machining requirements of the aerospace fasteners.

[0003] During the operation of the cutting mechanism in the aerospace fastener processing mechanism, a large amount of spatter is generated. If it is difficult to accurately intercept these metal splashes, it will cause the disadvantage of difficulty in collecting recyclable materials. The splashed metal may also damage other equipment and tools in the vicinity. Therefore, it is necessary to design an aerospace fastener processing mechanism with spatter interception effect to solve the above problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a processing mechanism for aerospace fasteners. In this solution, an arc-shaped protective mesh cover can be set outside the splash path of metal objects over a large area. When metal splashes are generated, the electromagnetic inner liner mesh of the arc-shaped protective mesh cover is energized to generate magnetic force, which tightly adheres the splashed metal fragments to the inner side of the arc-shaped protective mesh cover, effectively blocking the splashed metal objects to the maximum extent and effectively ensuring the service life of the equipment.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A processing mechanism for aerospace fasteners includes a cutting mechanism. A clamping seat is fixedly connected to the vertical surface of the cutting mechanism. A clamping inner hole is provided at the center of the front end of the clamping seat. The output end of the clamping inner hole clamps the fastener body. A cutting tool is fitted on the outer side of the fastener body. An annular guide rail is fixedly connected to one end of the clamping seat near the fastener body. An arc-shaped protective mesh cover is fixedly connected to the output end of the annular guide rail. The arc-shaped protective mesh cover is located on the outer side of the fastener body. An electromagnetic inner liner mesh is fixedly connected to the inner side of the arc-shaped protective mesh cover. An opening is provided on the left side of the arc-shaped protective mesh cover. An extension crossbar is fixedly connected to the upper end of the clamping seat. The extension crossbar extends directly above the arc-shaped protective mesh cover. A vibrator is fixedly connected to the lower end of the extension crossbar on the side away from the clamping seat. A rebound ball head is fixedly connected to the output end of the vibrator.

[0009] Furthermore, the rebound ball head contacts the outer wall of the arc-shaped protective netting, and a reinforcing middle ring is fixedly connected to the middle of the outer end of the arc-shaped protective netting.

[0010] Furthermore, the reinforcing ring is located directly below the spring-loaded ball head, and a chip storage groove is provided on the side of the horizontal surface of the cutting mechanism.

[0011] Furthermore, the chip storage groove corresponds to the opening, and a perforated screen is detachably connected to the middle of the lower inner wall of the chip storage groove.

[0012] Furthermore, an electric push rod is connected to the end of the cutting tool away from the clamping seat, and the electric push rod is connected to an external device terminal.

[0013] Furthermore, a blade is installed at one end of the cutting tool near the fastener body, and a controller is built into the device terminal.

[0014] Furthermore, the controller is electrically connected to the electromagnetic inner liner mesh, the annular guide rail, and the vibrator via wires.

[0015] 3. Beneficial Effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) In this scheme, the arc-shaped protective net can be set outside the splash path of metal objects on a large area. When metal splashes are generated, the electromagnetic inner layer mesh surface in the arc-shaped protective net is energized to generate magnetic force, which tightly adheres the splashed metal debris to the inner side of the arc-shaped protective net, effectively blocking the splashed metal objects to the maximum extent. At the same time, after the cutting operation is completed, the arc-shaped protective net can limit the metal splashes within its range and make the arc-shaped protective net rotate through the ring guide rail. At this time, the electromagnetic inner layer mesh surface is de-energized. After the de-energization, the metal objects inside can slide down the arc-shaped inner wall of the electromagnetic inner layer mesh surface into the chip storage groove, which is convenient for collecting and cleaning the overall debris and recycling and utilization.

[0018] (2) When the debris slides out of the arc-shaped protective net mask, the extended crossbar can be used to drive the vibrator to make the rebound ball head contact the reinforced middle ring, so that the smaller debris attached to the electromagnetic inner layer mesh is shaken out, making the subsequent protective effect of the arc-shaped protective net mask better.

[0019] (3) At the same time, a small hole screen can be set in the chip storage groove. The small hole screen can immediately classify and screen the splashed debris according to its size, making the collection effect more flexible. Attached Figure Description

[0029] Please see Figure 1-3 A processing mechanism for aerospace fasteners includes a cutting mechanism 1. A clamping seat 2 is fixedly connected to the vertical surface of the cutting mechanism 1. A clamping inner hole 16 is provided in the middle of the front end of the clamping seat 2. The output end of the clamping inner hole 16 clamps the fastener body 13. A cutting tool 12 is provided on the outer side of the fastener body 13. An annular guide rail 3 is fixedly connected to one end of the clamping seat 2 near the fastener body 13. An arc-shaped protective mesh cover 4 is fixedly connected to the output end of the annular guide rail 3. The arc-shaped protective mesh cover 4 is located on the outer side of the fastener body 13. An electromagnetic inner liner mesh 5 is fixedly connected to the inner side of the arc-shaped protective mesh cover 4. An opening 6 is provided on the left side of the arc-shaped protective mesh cover 4. An extension crossbar 9 is fixedly connected to the upper end of the clamping seat 2. The extension crossbar 9 extends to the top of the arc-shaped protective mesh cover 4. A vibrator 10 is fixedly connected to the lower end of the extension crossbar 9 away from the clamping seat 2. A rebound ball head 11 is fixedly connected to the output end of the vibrator 10.

[0030] Please see Figure 1-4The rebound ball head 11 is in contact with the outer wall of the arc-shaped protective net cover 4. A reinforcing middle ring 15 is fixedly connected to the middle of the outer end of the arc-shaped protective net cover 4. The reinforcing middle ring 15 is located directly below the rebound ball head 11. A chip storage groove 7 is provided on the upper side of the horizontal surface of the cutting mechanism 1. The chip storage groove 7 corresponds to the opening 6. A small hole screen 14 is detachably connected to the middle of the lower inner wall of the chip storage groove 7. An electric push rod 17 is connected to the end of the cutting tool 12 away from the clamping seat 2. An equipment terminal is connected to the electric push rod 17. A blade 18 is installed at the end of the cutting tool 12 near the fastener body 13. The equipment terminal has a built-in controller. The controller is electrically connected to the electromagnetic inner layer mesh 5, the annular guide rail 3, and the vibrator 10 through wires.

[0031] Please see Figure 1-4 In this solution, the fastener body 13 is correctly installed in the clamping inner hole 16 of the clamping seat 2. The cutting tool 12 is used to further cut the clamping inner hole 16 with the corresponding cutting depth and feed rate to achieve the final dimensional accuracy and surface quality requirements of the fastener body 13. During the processing, an arc-shaped protective mesh cover 4 can be set on the outside of the fastener body 13. The arc-shaped protective mesh cover 4 can be set on a large area outside the splash path of metal. The opening 6 on its left side can accommodate the displacement of the cutting tool 12. When metal splashes are generated, the electromagnetic inner mesh layer 5 in the arc-shaped protective mesh cover 4 is energized to generate magnetic force, which tightly adheres the splashed metal fragments to the inner side of the arc-shaped protective mesh cover 4, effectively blocking the splashed metal to the maximum extent and extending the service life of the equipment. At the same time, after the cutting operation is completed, the arc-shaped protective mesh cover 4 can trap the metal splashes. The object is confined within its range, and the arc-shaped protective mesh cover 4 is rotated via the annular guide rail 3. After rotation, the opening 6 is in a downward position, directly facing the opening of the chip storage groove 7. At this time, the electromagnetic inner liner mesh 5 is de-energized. After de-energization, the metal objects inside can slide down the arc-shaped inner wall of the electromagnetic inner liner mesh 5 into the chip storage groove 7, facilitating the collection and cleaning of the overall debris for recycling and utilization. At the same time, when the debris slides out of the arc-shaped protective mesh cover 4, the extension crossbar 9 can be used to drive the vibrator 10 to make the rebound ball head 11 contact the reinforcing middle ring 15, shaking out the smaller debris adhering to the electromagnetic inner liner mesh 5, thus improving the subsequent protective effect of the arc-shaped protective mesh cover 4. Meanwhile, a small-hole screen 14 can be set in the chip storage groove 7. The small-hole screen 14 can immediately classify and screen the splashed debris by size, making the collection effect more flexible.
