Description

Technical Field

[0001] The utility model relates to the technical field of hole punching for aircraft parts, and more specifically to a hole punching machine for processing aircraft parts. Background Art

[0002] In the prior art, punching machines for processing aircraft parts have the following shortcomings: First, punching machines are generally designed as single-station working modes. Although this simplifies the structure of the machine, it significantly reduces production efficiency when processing large quantities or diversified aircraft parts. The limitation of a single station means that only one component can be processed at a time, which will cause an obvious production capacity bottleneck, extend the production cycle, and increase production costs.

[0003] Secondly, in order to maintain the performance of the drill bit and prevent overheating during operation, traditional drilling machines usually need to use coolant to remove waste chips and cool the drill bit. However, the connection between the nozzle and the pipeline is relatively complicated, which not only increases the difficulty of maintenance, but also reduces the operational flexibility of the machine. Especially when the nozzle needs to be replaced quickly to adapt to different processing requirements, the complex connection mechanism may cause longer downtime and affect production efficiency.

[0004] In addition, the existing punching machines are equipped with a rotating disk for short-term buffering of coolant, which can collect and reuse the coolant during the punching process. However, when the equipment stops working and needs to drain the coolant, it is generally necessary to disassemble the rotating disk and rely on an external pipeline to drain the liquid, which is a cumbersome operation. Moreover, when the external pipeline is not connected, the sealing of the rotating disk cannot usually be effectively guaranteed, which may cause coolant leakage or pollute the working environment, and have an adverse effect on the maintenance and operational safety of the equipment.

[0033] In this embodiment, when the device is needed to perform drilling processing on aircraft parts, the parts to be processed are fixed one by one to the fixed assembly 4 arranged inside the rotating disk 2, and then the motor 19 is turned on. After the motor 19 is decelerated by the reducer 20, it drives the rotating shaft 3 to rotate, thereby driving the parts fixed on the rotating disk 2 to rotate. When the corresponding fixed assembly 4 moves below the corresponding punching assembly 5, the motor 19 is turned off, and then the punching assembly 5 is turned on to perform drilling processing on the parts fixed on the fixed assembly 4, and at the same time, the external input is turned on.

When the waste liquid is discharged, the output pipe is removed, and then the sealing plate 27 will lose the reset of the push rod, and then the push spring 28 will drive the sealing plate 27 to reset, and make the sealing block 32 engage in the sealing groove 33 again, so that the sealing tube 24 is sealed again, thereby ensuring the sealing performance of the rotating disk 2.

[0037] In summary, when the equipment is used: when the equipment needs to be used to perform drilling processing on aircraft parts, the parts to be processed are fixed one by one to the fixed assembly 4 set on the inner side of the rotating disk 2, and then the motor 19 is turned on.

Due to the unique chamfer design inside the clamping groove 17, when one end of the clamping frame 15 is completely engaged in the clamping groove 17, it will drive the clamping tube 9 to press the gasket 16, and then the multiple gaskets 22 arranged on the outside of the clamping tube 9 will engage in the corresponding clamping groove 23, thereby ensuring a high degree of sealing at the connection while realizing rapid replacement of the nozzle 7.
