[0001] This utility model relates to the field of cutting device technology, and in particular to a precise skin cutting device. Background Technology

[0002] Aircraft skin is a shell covering the outside of the aircraft's frame structure. It is usually made of metal (such as aluminum alloy) or composite materials. It not only forms the aerodynamic shape of the aircraft, reducing air resistance during flight, but also withstands aerodynamic and pressure loads during flight. During the production of the skin, a cutting machine is used to cut the skin to the required size.

This device includes a cutting platform with a cutting mechanism and a fixing mechanism at its top. The fixing mechanism comprises a first fixing block, a second fixing block, and a third fixing block. Each of the first, second, and third fixing blocks has a fixing groove on its outer surface. An adjustment mechanism is located inside each fixing groove, comprising a clamping block, an adjusting rod, and a spring. The clamping block is positioned inside the fixing groove. The bottom end of the adjusting rod penetrates the outer surface of the fixing mechanism and is movably inserted into the fixing groove. The bottom end of the adjusting rod is fixedly connected to the top end of the clamping block, and the bottom end of the spring is fixedly connected to the top end of the clamping block. The top end of the spring is fixedly connected to the top end of the fixing groove, and the spring is sleeved on the outer surface of the adjusting rod. This aluminum alloy skin cutting device facilitates the fixing of aluminum alloy skins of different thicknesses and makes the skin cutting process easier.

[0004] The above-mentioned and existing technologies have the following drawbacks: During the cutting process of the skin, the operator needs to push the skin to move. Since the skin is heavy, it is more strenuous for the operator to operate, which increases the operator's workload and reduces the practicality of the cutting machine.

[0005] Therefore, a precise skin cutting device is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of heavy skin, which makes operation more strenuous for workers, increases their workload, and reduces the practicality of the cutting machine. Therefore, this invention proposes a precise skin cutting device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a skin precision cutting device, comprising...

[0024] Preferably, the upper surface of the fixing block is threaded with bolts, and the bolts pass through the fixing block and abut against the upper surface of the connecting plate.

[0025] The effect achieved by the above components is that when the bolt is pressed against the surface of the connecting plate, the bolt will restrict the position of the connecting plate, thereby restricting the position of the limiting plate.

[0037] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0039] like Figures 1-4 As shown, this utility model provides a precision skin cutting device, including a cutting table 1, a bracket 2 fixedly mounted on the upper surface of the cutting table 1, a lead screw 3 rotatably connected inside the bracket 2, a servo motor 4 fixedly mounted on the side wall of the bracket 2, the output end of the servo motor 4 fixedly connected to the lead screw 3, a movable frame 5 threadedly connected to the outer circumferential surface of the lead screw 3, the movable frame 5 slidably connected to the bracket 2, a first electric push rod 6 fixedly mounted on the surface of the movable frame 5, a mounting bracket 26 slidably connected to the movable frame 5 fixedly mounted on the output end of the first electric push rod 6, and a drive motor 7 fixedly mounted on the surface of the mounting bracket 26, the output end of the drive motor 7 being fixedly mounted on the side wall of the bracket 2. A cutting disc 8 is fixedly mounted on the cutting table 1. Several L-shaped plates 9 are fixedly mounted on the lower surface of the cutting table 1. A round rod 10 slides through the L-shaped plate 9. A rectangular frame 11 is fixedly mounted on the upper end of the round rod 10. Several fixing plates 12 are fixedly mounted on the upper surface of the rectangular frame 11. The fixing plates 12 pass through the cutting table 1. A roller 13 is rotatably connected inside the fixing plates 12. A spring 14 is sleeved on the arc surface of the round rod 10. The two ends of the spring 14 are fixedly connected to the L-shaped plate 9 and the cutting table 1, respectively. A second electric push rod 15 is fixedly mounted on the lower surface of the cutting table 1. A pressure plate 16 is fixedly mounted on the output end of the second electric push rod 1 through the cutting table 1.

[0040] The surface of the cutting table 1 is provided with a clearance hole 17. A guide frame 18 is fixedly installed on the lower surface of the cutting table 1. The guide frame 18 is connected to the clearance hole 17. Some of the debris generated during cutting will fall into the guide frame 18 through the clearance hole 17. After that, the debris will fall out of the guide frame 18. The guide frame 18 achieves the function of reducing the scattering range of debris and facilitating the collection of debris.

[0041] A damping plate 19 is fixedly mounted on the side wall of the L-shaped plate 9. The damping plate 19 is slidably connected to the rectangular frame 11. The damping plate 19 can prevent the spring 14 from reciprocating after the skin is placed on the roller 13.

[0042] A fixing block 20 is fixedly mounted on the upper surface of the cutting table 1. A connecting plate 21 slides through the fixing block 20. A limiting plate 22 is fixedly mounted on the surface of the connecting plate 21. During the movement of the skin along the outer circumference of the roller 13, the limiting plate 22 restricts the movement path of the skin to prevent the skin from shifting during the movement.

[0043] The upper surface of the fixing block 20 is threaded with a bolt 23. The bolt 23 passes through the fixing block 20 and abuts against the upper surface of the connecting plate 21. When the bolt 23 abuts against the surface of the connecting plate 21, the bolt 23 will restrict the position of the connecting plate 21, thereby restricting the position of the limiting plate 22.

[0044] The upper surface of the connecting plate 21 is provided with a scale groove 24, which facilitates the adjustment of the positions of the two limit plates 22.

[0045] A rectangular plate 25 that slides through the cutting table 1 is fixedly mounted on the lower surface of the pressure plate 16. When the pressure plate 16 moves, it will cause the rectangular plate 25 to slide along the cutting table 1. The rectangular plate 25 will restrict the movement path of the pressure plate 16.

[0046] The overall working principle is as follows: When cutting the skin, the skin is placed on the roller 13. At this time, the spring 14 is in a compressed state. The spring 14 will support the rectangular frame 11 with its own elasticity, thereby preventing the skin from contacting the cutting table 1 during movement. Therefore, the operator can easily move the skin. The damping plate 19 can prevent the spring 14 from bouncing back and forth after the skin is placed on the roller 13. During the movement of the skin along the outer circumference of the roller 13, the limiting plate 22 will restrict the movement path of the skin to prevent the skin from shifting during movement, thus facilitating the movement of the skin. When the bolt 23 abuts against the surface of the connecting plate 21, the bolt 23 will restrict the position of the connecting plate 21, thereby restricting the position of the limiting plate 22. The scale groove 24 facilitates the adjustment of the positions of the two limiting plates 22. When the skin moves to the appropriate position, the output end of the second electric push rod 15 is controlled to retract, and the pressure plate 16... The pressure plate 16 moves downwards, causing the rectangular plate 25 to slide along the cutting table 1. The rectangular plate 25 restricts the movement path of the pressure plate 16. After the pressure plate 16 contacts the skin, it squeezes the skin, which in turn squeezes the roller 13. The roller 13 then moves the fixed plate 12 until the skin contacts the cutting table 1. At this point, the pressure plate 16 restricts the position of the skin. Then, the servo motor 4 drives the lead screw 3 to rotate, which in turn drives the moving frame 5 to move. The moving frame 5 then drives the first electric push rod 6 to move, which in turn drives the mounting frame 26 to move. The mounting frame 26 then drives the drive motor 7 to move. The drive motor 7 is then turned on, causing the cutting blade 8 to rotate. When the cutting blade 8 contacts the skin, it cuts the skin. Some of the debris produced during cutting falls into the guide frame 18 through the clearance hole 17. The debris then falls out of the guide frame 18, which reduces the area where the debris falls and facilitates its collection.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
