Description
Technical Field
[0001] This utility model relates to the field of aerospace manufacturing technology, and in particular to a clamping device for processing aerospace fasteners. Background Technology
[0002] Aviation fasteners, also known as aviation fixtures, are key components used to connect and secure parts in aviation assembly. They not only bear the weight of the aircraft structure but also ensure the stability and safety of the aircraft in complex flight environments. During the processing of aviation fasteners, they need to be clamped and secured.
[0003] Existing clamping devices for aerospace fasteners use cylinders or motors to drive lead screws to clamp and fix the fasteners. However, because aerospace fasteners have high precision requirements, existing clamping devices cannot adjust the clamping force during clamping, which can easily cause deformation of the fasteners and is quite inconvenient.
[0004] Therefore, an aviation fastener processing clamping device has been developed to facilitate the adjustment of clamping force on aviation fasteners, prevent deformation of the fasteners during clamping, and improve the processing quality of the fasteners. Utility Model Content

[0006] The technical solution of this utility model is as follows: a clamping device for processing aviation fasteners, comprising a base plate, a fixing block, a motor, a lead screw, a baffle, an alarm, a moving plate, a clamping assembly, and a cleaning assembly. The fixing block is connected to the upper right side of the base plate, the motor is connected to the right side of the fixing block, the baffle is connected to the upper middle part of the fixing block, the lead screw is rotatably connected between the baffle and the fixing block, the lead screw is connected to the output shaft of the motor, the moving plate is threadedly connected to the lead screw, the alarm is connected to the upper side of the fixing block, the moving plate is provided with a clamping assembly capable of clamping the fastener, and the clamping assembly is provided with a cleaning assembly capable of cleaning.
[0007] In one embodiment, a telescopic sleeve is also included, with the telescopic sleeve connecting the movable plate and the baffle, and the telescopic sleeve also connecting the movable plate and the fixed block.
[0008] In one embodiment, the clamping assembly includes guide posts, springs, adjusting rods, probes, and pins. Two guide posts are slidably connected to the upper part of the movable plate, and springs are connected between each guide post and the movable plate.

[0009] In one embodiment, the adjusting rod has multiple adjusting slots.
[0010] In one embodiment, the cleaning assembly includes a fixed plate, a gasket, a connecting rod, a brush column, and a limiting block. The fixed plate is connected to the upper left side of the base plate, the upper right side of the fixed plate is connected to the gasket, and the left side of the guide column is also connected to the gasket. The connecting rod is rotatably connected to the front upper side of the fixed plate, and the brush column is rotatably connected to the rear right side of the connecting rod.

[0011] In one embodiment, a rocker arm is also included, which is rotatably connected to the front right side of the connecting rod and is connected to the brush post.

Detailed Implementation
[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0021] A clamping device for machining aerospace fasteners, such as Figure 1 and Figure 2 As shown, the assembly includes a base plate 1, a fixing block 2, a motor 3, a lead screw 4, a baffle 5, a telescopic sleeve 6, an alarm 7, a movable plate 8, a clamping assembly, and a cleaning assembly. The base plate 1 is connected to the upper right side of the fixing block 2, the motor 3 is connected to the right side of the fixing block 2, the baffle 5 is connected to the upper middle part of the fixing block 2, the lead screw 4 is rotatably connected between the baffle 5 and the fixing block 2, the lead screw 4 is connected to the output shaft of the motor 3, the movable plate 8 is threadedly connected to the lead screw 4, the alarm 7 is connected to the upper side of the fixing block 2, the movable plate 8 is connected to the baffle 5, the movable plate 8 is also connected to the fixing block 2, the movable plate is provided with a clamping assembly, and the clamping assembly is provided with a cleaning assembly.
[0022] like Figure 3 As shown, the clamping assembly includes guide posts 9, springs 10, adjusting rods 11, probes 12, and pins 13. Two guide posts 9 are slidably connected to the upper part of the moving plate 8, and springs 10 are connected between each guide post 9 and the moving plate 8. An adjusting rod 11 is also slidably connected to the upper part of the moving plate 8. The adjusting rod 11 is located above the guide posts 9. Two probes 12 are connected to the left side of the adjusting rod 11. A pin 13 is snapped into the upper side of the moving plate 8. The pin 13 is snapped into the adjusting rod 11. The adjusting rod 11 has multiple adjustment slots to facilitate the adjustment of the position of the adjusting rod 11.
[0023] like Figure 4 and Figure 5 As shown, the cleaning assembly includes a fixed plate 14, a gasket 15, a connecting rod 16, a brush column 17, a rocker arm 18, and a limiting block 19. The fixed plate 14 is connected to the upper left side of the base plate 1. The gasket 15 is located on the upper right side of the fixed plate 14. A gasket 15 is also connected between the left sides of the guide column 9. The connecting rod 16 is rotatably connected to the upper front side of the fixed plate 14. The brush column 17 is rotatably connected to the right rear side of the connecting rod 16. The limiting block 19 is connected to the upper part of the fixed plate 14. The limiting block 19 is in contact with the connecting rod 16. The rocker arm 18 is rotatably connected to the right front side of the connecting rod 16. The rocker arm 18 is connected to the brush column 17.
[0024] When using this utility model, first place the base plate 1 in the processing area of the aviation fixture, then rotate the connecting rod 16 on the fixing plate 14 to rotate the brush column 17 out of the space between the pads 15. Then place the aviation fixture to be processed between the pads 15. Then start the motor 3 to make the lead screw 4 rotate between the baffle 5 and the fixing block 2. The telescopic sleeve 6 can shield the lead screw 4 to prevent the processing debris from affecting the normal use of the lead screw 4. Under the action of the thread, the moving plate 8 slides to the left, thereby driving the guide column 9 on the moving plate 8 to move to the left, so that the pads 15 come into contact with each other, pushing the guide column 9 to slide on the moving plate 8. The spring 10 is compressed and contracts, pressing the pads 15 to clamp the aviation fixture. During the sliding of the guide column 9, the pads 15 on the guide column 9 will come into contact with the probe 12. The probe 12 is pressed and monitored. When the pressure reaches the required clamping force, the motor 3 stops and the alarm 7 issues a warning signal. This allows for easy adjustment of the clamping force of the aircraft fastener, preventing deformation of the fastener and improving the processing quality of the fastener. By pulling out the pin 13, the position of the adjusting rod 11 can be adjusted, thereby adjusting the position of the probe 12 to meet the clamping requirements of different sized aircraft fasteners. After adjustment, the pin 13 can be reinserted to fix the adjusting rod 11. After the fastener is processed, the connecting rod 16 can be rotated back between the pads 15. The connecting rod 16 is limited by the limit block 19. Then, the rocker arm 18 is rotated to make the brush column 17 rotate, so that the brush column 17 cleans the pads 15 and prevents the processing debris from causing deformation of the fastener.
