[0023] Working principle and advantages of the present invention: When the cutting device for the aircraft seat rail beam is used, the working process is as follows: like Figure 1 and Figure 2As shown, the workpiece to be cut is passed through the movable clamping frame 28, the fixed clamping frame 27 and the inner side of the fixed frame 10 from left to right in sequence. After adjusting the end position of the workpiece, the cylinder 5 and the motor 8 are started, so that the cylinder 5 pushes the lifting rod 6 to descend, thereby causing the lifting rod 6 to drive the suspension rod 7, the connecting rod 14 and the two pressure rods 11 to move downward, and the connecting rod 14 drives the slide plate 13 to move downward, and the slide plate 13 drives the slide plate 2 17 to move downward through the spring 15, so that the slide plate 2 17 transports the air in the slide cylinder 12 to the slide cylinder 2 19 through the air pipe 21, and then the slide plate 3 20 drives the rack 22 to move left and drives the toothed disc 24 to rotate clockwise, so that the toothed disc 24 drives the movable clamping frame 28 to move rightward to the fixed clamping frame 27 through the rocker 25 and the pin rod 18, as shown in FIG. Figure 4 and Figure 5As shown, under the action of spring four 51, the two clamping plates 48 always drive the rubber pads 49 to fit with the workpiece, and the rubber pads 49 play a role in increasing friction and protecting the surface of the workpiece from wear. When the movable clamping frame 28 moves, the connecting rod four 50 applies a thrust to the rubber pads 49, so that the combined force direction of the friction force of the rubber pads 49 on the workpiece and the pressure of the rubber pads 49 on the workpiece is directed to the workpiece, so that the rubber pads 49 can drive the workpiece to move together, and at the same time, the friction force of the rubber pads 49 on the workpiece in the fixed clamping frame 27 is perpendicular to the workpiece. The elastic force of the spring four 51 is overcome, so that the workpiece can be moved in the fixed clamping frame 27. When the slide plate two 17 is in contact with the convex ring 16, the swing rod 25 is in a vertical state and stops swinging, so as to convey the workpiece of the set length. At this time, the lower end of the pressure rod 11 is in contact with the corresponding cross plate 29, and the pressure rod 11 drives the guide cylinder one 30 and the slide rod two 41 to move downward while the lifting rod 6 continues to move downward, thereby driving the slide rod one 32 and the pressure plate 33 downward through the spring two 31, and the slide rod two 41 drives the guide cylinder two 42 downward through the spring three 43. When the guide cylinder 2 42 moves downward, its internal partition compresses the spring 5 52, and the spring 5 52 obtains a restoring force. When the guide cylinder 2 42 moves downward, the pin rod 2 46 moves downward through the connecting rod 3 45, so that the pin rod 2 46 drives the connecting rod 2 39 to rotate, and then the connecting rod 2 39 pushes the clamping plate 1 34 to approach the workpiece through the slider 36. When the pressure plate 33 contacts the upper surface of the workpiece and the clamping plate 1 34 contacts the side of the workpiece, the cutting disc 9 is about to cut the workpiece. As the lifting rod 6 continues to move downward, the cutting disc 9 cuts the workpiece. , and during the cutting process, the pressure rod 11 continues to apply downward pressure to the cross plate 29, so that the pressure plate 33 and the two clamping plates 1 34 can clamp the workpiece more tightly, and the spring 2 31, the spring 3 43 and the spring 5 52 can eliminate the vibration transmission generated by the motor 8, maintain the stability of the workpiece during cutting, and improve the cutting accuracy. The two sets of clamping mechanisms clamp the workpiece and the cut part respectively, thus avoiding the problem of uneven cutting surface caused by the instability of the part to be cut at the end of the cutting, and no manual operation is required to clamp the workpiece, saving time and effort.

[0024] As described above, after the cutting is completed, the cylinder 5 is started to drive the lifting rod 6 to move upward, so that the lifting rod 6 simultaneously drives the suspension rod 7, the connecting rod 14 and the two pressure rods 11 to move upward, and the pressure rod 11 moves upward and resets, so that the cross plate 29 is not subjected to downward pressure, and is driven upward and reset by the slide bar 2 41 under the restoring force of the spring 5 52 and the spring 3 43, thereby making the cross plate 29 drive the guide cylinder 1 30 to move upward and reset, and at the same time, the slide bar 1 32 and the pressure plate 33 at its lower end are driven upward and reset through the spring 2 31, and the guide cylinder 2 42 moves upward and reset under the restoring force of the spring 5 52, so that The guide cylinder 2 42 drives the connecting rod 3 45 and the pin 2 46 thereon to move upward, and then the pin 2 46 drives the connecting rod 2 39 to rotate in the opposite direction, so that the connecting rod 2 39 drives the clamping plate 1 34 to loosen the workpiece through the slider 36 and the slide rail 35, and releases the clamping fixation of the workpiece. After the connecting rod 14 moves upward, it drives the slide plate 13 to move upward and reset, so that the slide plate 13 synchronizes with the spring 15 to drive the slide plate 2 17 to move upward and reset. In the process of resetting the slide plate 2 17, the air in the slide cylinder 2 19 is sucked into the slide cylinder 12 through the air pipe 21, so that the slide plate 3 20 drives the rack 22 to Figure 1 , Figure 2 The gear plate 24 drives the swing rod 25 to rotate counterclockwise, so that the swing rod 25 drives the clamping frame 28 through the pin 18. Figure 1 , Figure 2 The movable clamping frame 28 moves leftward, thereby driving the rubber pad 49 inside it to move leftward relative to the workpiece. Therefore, the friction force of the rubber pad 49 on the workpiece in the movable clamping frame 28 overcomes the elastic force of the spring four 51 in the direction perpendicular to the workpiece, thereby enabling the rubber pad 49 to move leftward relative to the workpiece. In the fixed clamping frame 27, the workpiece has a tendency to move leftward relative to the rubber pad 49 inside the fixed clamping frame 27. Therefore, the thrust of the connecting rod four 50 in the fixed clamping frame 27 and the friction force of the rubber pad 49 on the workpiece are directed to the workpiece, so that the workpiece cannot move leftward, avoiding the workpiece being driven to move leftward while the movable clamping frame 28 moves leftward, thereby ensuring that the feeding length is accurate and stable, realizing automatic feeding, and greatly improving work efficiency.
