Description

Technical Field

[0001] This utility model relates to the field of machining stiffening rib processing technology, specifically a cutting machine for machining aircraft stiffening ribs that can cut at fixed distances. Background Technology

[0002] Stiffening ribs are strip-shaped reinforcements installed at supports or locations with concentrated loads to ensure the local stability of a beam and to transfer concentrated forces, thereby improving the beam's stability and torsional resistance. Stiffening ribs are suitable for being installed in pairs on both sides of the web, but can also be installed on one side only.

[0003] According to a published application for a plasma cutting machine capable of fixed-distance cutting (publication number: CN221560101U), the aforementioned application includes an adjustable distance structure. When the second drive motor is started, its rotation drives the gear to rotate via a connecting shaft. The gear rotates and moves back and forth along the rack plate. As the gear moves, it drives the limit frame to move simultaneously via the connecting shaft. This allows adjustment of the position of the limit frame above the base, changing the distance between the cutting head and the limit frame. This enables the device to perform fixed-distance cutting, improving the working efficiency of the plasma cutting machine capable of fixed-distance cutting during use.

[0004] However, in actual use, the above-mentioned equipment requires manual adjustment of the material clamping when cutting at a fixed distance. When it is necessary to cut the material at a fixed distance, the material clamping needs to be adjusted manually repeatedly to ensure that the material can be cut, which wastes a lot of time and manpower. In view of this, we propose a cutting machine for processing aircraft stiffening ribs that can cut at a fixed distance. Utility Model Content

[0008] A hinge plate is hinged to the outer wall of a rotating plate. A slider is hinged to the end of the hinge plate away from the rotating plate. A compression spring is fixedly connected to the outer wall of the slider. A sliding rod is slidably connected through the outer wall of the slider.

[0009] Preferably, the base is provided with a clamping assembly, which includes a push plate. The push plate is fixedly connected to the outer wall of the housing. A limit block is fixedly connected to the outer wall of the push plate. A clamping plate is slidably connected through the inner wall of the base. A return spring is fixedly connected to the outer wall of the clamping plate, so that when the cutting blade descends, it can push the push plate to extend the clamping plate from the base and clamp the material.

[0010] Preferably, a friction pad is provided at one end of the clamping plate near the outer wall of the base, and an inclined surface is provided on the lower outer wall of the push plate. The push plate contacts the clamping plate, and the friction pad can make the clamping plate contact the material more firmly, preventing the material from loosening. When the push plate moves downward, it can make the clamping plate move through the inclined surface on the push plate.

[0011] Preferably, the outer wall of the housing is provided with a sliding groove, the sliding rod is fixedly connected to the inner wall of the sliding groove, the compression spring is sleeved on the outer wall of the sliding rod, and the end of the slider away from the compression spring is fixedly connected to the inner wall of the sliding groove, so that when the roller presses the material and the cutting blade descends, the rotating plate rotates to move the material on the roller, while the slider moves on the sliding rod and presses the compression spring, and the compression spring applies pressure to the roller.

[0012] Preferably, the length of the rotating plate is greater than the length of the cutting blade, and both ends of the cutting blade are provided with clamping components, so that the rotating plate can directly clamp the material when the cutting blade descends to cut the material.

[0013] Preferably, the end of the return spring away from the clamping plate is fixedly connected to the inner wall of the base, and the thickness of the push plate is greater than the distance between the clamping plate and the outer wall of the base, so that when the push plate descends, it can push the side of the clamping plate with the friction pad into the base. Both ends of the material are provided with clamping components, so that the clamping plate can calibrate the position of the material when clamping the material.

[0014] Preferably, a movable groove is provided on the outer wall of the base, and the push plate passes through the movable groove and is fixedly connected to the sleeve, so that when the cutting blade moves down, the sleeve can drive the push plate to calibrate and clamp the material.

[0015] Compared with the prior art, this utility model provides a cutting machine for machining aircraft stiffening ribs that can cut at fixed distances, which has the following beneficial effects:

[0016] 1. This aircraft stiffening rib processing cutting machine with fixed-distance cutting capability uses a baffle to move, allowing the cutting blade to cut at a specified distance. When the cutting blade descends, the rotating plate rotates, causing the rollers to move on the material. The rollers apply pressure to the material, allowing it to be better held in place. When the cutting blade descends to cut the material, the rollers can directly clamp the material. When the cutting blade rises, the rollers move away from the material, allowing it to move. This eliminates the need for repeated tightening and loosening of the material, saving time and manpower.

[0017] 2. The cutting machine for processing stiffening ribs of this aircraft can cut at a fixed distance. When the casing moves, the push plate moves down and pushes out the side of the clamping plate with friction pads to clamp the material. Both ends of the material are equipped with clamping components, so that the clamping plate can calibrate the position of the material when clamping it, making the cutting of the material more accurate.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a cutting machine for processing aircraft stiffening ribs with fixed-distance cutting, including a base 1, a conveyor wheel 2 rotatably connected to the inner wall of the base 1, a hydraulic rod 3 fixedly connected to the upper outer wall of the base 1, the output end of the hydraulic rod 3 passing through the outer wall of the base 1 and fixedly connected to a cutting blade 4, an electric push rod 5 fixedly connected to the end of the base 1 away from the conveyor wheel 2, a baffle 6 fixedly connected to the output end of the electric push rod 5, an ejector rod 7 fixedly connected to the outer wall of the base 1, an inclined plate 8 fixedly connected to the end of the base 1 away from the ejector rod 7, and a pressing assembly 9 provided inside the base 1, the pressing assembly 9 including a housing 91, a rotating plate 92, a roller 93, a friction sleeve 94, a hinge plate 95, a slider 96, a compression spring 97, and a sliding rod 98.

[0024] In one embodiment of this utility model, the housing 91 is fixedly connected to the output end of the hydraulic rod 3, and a rotating plate 92 is rotatably connected to the outer wall of the housing 91. A roller 93 is sleeved on the end of the rotating plate 92 away from the housing 91, and a friction sleeve 94 is fixedly connected to the outer wall of the roller 93.

[0025] In one embodiment of the present invention, a hinge plate 95 is hinged to the outer wall of a rotating plate 92, and a slider 96 is hinged to the end of the hinge plate 95 away from the rotating plate 92. A compression spring 97 is fixedly connected to the outer wall of the slider 96, and a slide rod 98 is slidably connected through the outer wall of the slider 96.

[0026] In addition, a clamping assembly 10 is provided inside the base 1. The clamping assembly 10 includes a push plate 101, which is fixedly connected to the outer wall of the housing 91. A limit block 102 is fixedly connected to the outer wall of the push plate 101. A clamping plate 103 is slidably connected through the inner wall of the base 1. A return spring 104 is fixedly connected to the outer wall of the clamping plate 103, so that when the cutting blade 4 descends, it can push the push plate 101 to make the clamping plate 103 extend out of the base 1 to clamp the material and prevent the material from being misaligned during cutting.

[0027] In an embodiment of this utility model, a friction pad is provided at one end of the clamping plate 103 near the outer wall of the base 1, and an inclined surface is provided on the lower outer wall of the push plate 101. The push plate 101 contacts the clamping plate 103. The friction pad enables the clamping plate 103 to contact the material more firmly, preventing the material from loosening. When the push plate 101 moves downward, it enables the clamping plate 103 to move through the inclined surface on the push plate 101, so that the clamping plate 103 can be pushed out to clamp the material.

[0028] In an embodiment of this utility model, a groove is provided on the outer wall of the housing 91, the slide rod 98 is fixedly connected to the inner wall of the groove, the compression spring 97 is sleeved on the outer wall of the slide rod 98, and one end of the slider 96 away from the compression spring 97 is fixedly connected to the inner wall of the groove. When the roller 93 presses down on the material and the cutting blade 4 descends, the rotating plate 92 rotates, causing the roller 93 to move on the material. At the same time, the slider 96 moves on the slide rod 98 and presses down on the compression spring 97. The compression spring 97 applies pressure to the roller 93, so that the roller 93 applies pressure to the material, so that the material can be better pressed down.

[0029] In the embodiments of this utility model, the length of the rotating plate 92 is greater than the length of the cutting blade 4, and both ends of the cutting blade 4 are provided with clamping components 9. When the cutting blade 4 descends to cut the material, the roller 93 can directly clamp the material. When the cutting blade 4 rises, the roller 93 moves away from the material, allowing the material to move.

[0030] In this embodiment of the utility model, the end of the return spring 104 away from the clamping plate 103 is fixedly connected to the inner wall of the base 1. The thickness of the push plate 101 is greater than the distance between the clamping plate 103 and the outer wall of the base 1, so that when the push plate 101 descends, it can push the side of the clamping plate 103 with the friction pad out of the base 1. Both ends of the material are provided with clamping components 10, so that when the clamping plate 103 clamps the material, it can calibrate the position of the material, making the cutting of the material more accurate.

[0031] In an embodiment of this utility model, a movable groove is provided on the outer wall of the base 1, and the push plate 101 passes through the movable groove and is fixedly connected to the housing 91, so that when the cutting blade 4 moves down, the housing 91 can drive the push plate 101 to make the clamping plate 103 calibrate and clamp the material, so that the material cutting effect is better.

[0032] In this invention, during use, the electric actuator 5 pushes the baffle 6 to a designated position, allowing the cutting blade 4 to cut at a specified distance. Then, the material is placed on the base 1, and the material is pushed by the conveyor wheel 2 until one end of the material contacts the baffle 6. At this time, the cutting blade 4 is pushed by the hydraulic rod 3 to cut the material. The cut material is then pushed out by the push rod 7 and slides down the inclined plate 8. As the cutting blade 4 descends, the rotating plate 92 rotates, causing the roller 93 to move on the material, while the slider 96 moves on the slide rod 98 and presses down the compression spring 97. 7. Apply pressure to roller 93 so that roller 93 can press the material better. When the cutting blade 4 descends to cut the material, the rotating plate 92 can directly clamp the material. When the cutting blade 4 rises, roller 93 moves away from the material so that the material can move. When the housing 91 moves, push plate 101 moves down so that the side of clamping plate 103 with friction pad is pushed out. Both ends of the material are provided with clamping components 10 so that the clamping plate 103 can calibrate the position of the material when clamping it, so that the cutting of the material is more accurate.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
