Description

Technical Field

[0001] The utility model relates to the technical field of cargo hold wall panel bending, in particular to a rear cargo hold wall panel bending device. Background Art

[0002] The interior of an aircraft is a complex, carefully designed three-dimensional structure. Bulkhead panels need to be bent to fit the contours of the aircraft fuselage to make full use of the limited internal space. The space shape is curved. By bending the bulkhead panels, they can be tightly installed in these areas to avoid gaps or wasted space. It is like placing a liner in an irregularly shaped container. Only by bending the liner into a shape similar to the inner wall of the container can the space be better filled.

[0003] The cargo hold wall panels are made of aluminum alloy and composite materials. When bending the cargo hold wall panels made of aluminum alloy, the current common method is to place the product on a clamping device, then clamp one end of the product with a rotatable clamping device, and control the rotation of the clamping device to bend the product. Although this operation can bend the product, it is found during operation that the clamping device will tightly clamp the product when in use. When the clamping force is large, it is easy to damage the product, affecting the quality of the product and making the product unusable. Therefore, a rear cargo hold wall panel bending device is proposed to solve the above problem. Utility Model Content

[0031] In a preferred embodiment, the screw rod 321 is threadedly connected to the nut, and the moving block 33 is stably connected to the outside of the nut, and the interior of the mounting seat 32 is set to be hollow. The connecting block 4 is slidably installed inside the mounting seat 32, and the connecting block 4 is fixedly connected to the moving block 33. By installing the moving block 33 on the outside of the screw rod 321, the moving block 33 is fixedly connected to the nut. When the screw rod 321 rotates, the nut will drive the moving block 33 to move, thereby driving the push plate 331 to move, thereby pushing and bending the product.

[0032] In a preferred embodiment, a vertical plate 5 is installed on the upper surface of the base 1, and a cylinder 6 is fixedly installed on the outer side of the vertical plate 5, and a clamping plate 7 is fixedly installed on the telescopic end of the cylinder 6. To ensure stable processing of the product, a vertical plate 5 is installed on the base 1, and a cylinder 6 is installed on the outer side of the vertical plate 5, and a clamping plate 7 is installed on the telescopic end of the cylinder 6. The product can be clamped and released by moving the clamping plate 7, which facilitates stable processing of the product.

[0033] In a preferred embodiment, a partition 8 is fixedly installed on the top of the vertical plate 5 to prevent the product from jumping up. A sliding groove 9 is provided at the bottom of the partition 8, and a slider 10 is provided inside the sliding groove 9. One side of the slider 10 is fixedly connected to the clamping plate 7. When the product is squeezed, if the pressure is too high, the product may easily move upward and cause danger. Therefore, during processing, the product needs to be limited. Therefore, a partition 8 is provided on the top of the vertical plate 5 to limit the product and effectively prevent the product from moving upward and detaching from the side position of the vertical plate 5.

[0034] During actual use, the degree of bending of the product will be adjusted according to the processing requirements, so an arc plate 11 is fixedly installed on the outer side of the base 1, and the upper surface of the arc plate 11 is flush with the upper surface of the base 1. An anti-over-processing mechanism 12 is also installed on the arc plate 11. The anti-over-processing mechanism 12 includes a limit plate 121, an adjustment plate 122 and a pressure sensor 123. The limit plate 121 is fixedly installed on the upper surface of the base 1, and a hollow cylinder 13 is stably installed on one side of the limit plate 121, and a connecting rod 14 is slidably connected inside the hollow cylinder 13, and the connecting rod 14 is connected to the hollow cylinder 13 through an axle pin. An adjusting plate 122 is fixedly installed on one end of the connecting rod 14, and a pressure sensor 123 is inlaid on the outer side of the adjusting plate 122. The position of the pressure sensor 123 corresponds to the position of the push plate 331. The pressure sensor 123 is electrically connected to the PLC controller 15, and the PLC controller 15 is electrically connected to the control motor 31.

[0035] In actual use, the degree of bending of the product is controlled according to production needs, so as to adjust the length of the connecting rod 14 extending out of the hollow cylinder 13, control the connecting rod 14 to be retracted or extended inside the hollow cylinder 13, and stably connect the connecting rod 14 to the hollow cylinder 13 through the axle pin, so as to adjust the position of the adjusting plate 122, and control the position of the adjusting plate 122 to control the degree of bending of the product, and set the adjusting plate 122 on the outside of the product. When the product is pushed and bent, the adjusting plate 122 will be squeezed, and a pressure sensor 123 is installed on the adjusting plate 122. When the adjusting plate 122 is squeezed, the pressure sensor 123 will be squeezed. When the pressure sensor 123 detects the presence of pressure, it will control the control motor 31 to stop working through the PLC controller 15, thereby stopping further processing of the product.

[0036] Specifically, the working process or working principle of a rear cargo hold wall panel bending device is as follows: the cargo hold wall panels are made of aluminum alloy materials and composite materials, etc. When bending the cargo hold wall panels made of aluminum alloy materials, the current common method is to place the product on a clamping device, and then clamp one end of the product with a rotatable clamping device, and control the rotation of the clamping device to achieve bending of the product. Although this operation can bend the product, it is found during operation that the clamping device will tightly clamp the product when in use. When the clamping force is large, it is easy to damage the product, affecting the quality of the product and causing the product to be unusable. Therefore, this device is designed to solve this problem.

[0037] This device pushes the product to make it concave, thereby bending the product, effectively replacing the method of clamping and bending the product, avoiding damage to the product, and ensuring the quality of the product. The specific operation is to connect the external power supply, place the product on the base 1, and place the product on one side of the vertical plate 5 so that the outer side of the product is in close contact with the side of the vertical plate 5, and then open the cylinder 6. The telescopic end of the cylinder 6 will drive the clamping plate 7 to move, and the upper end of the product will be clamped by the clamping plate 7, so that the product is stably installed on the side of the vertical plate 5.

[0038] Then turn on the control motor 31, drive the transmission rod 311 to rotate through the control motor 31, and drive the driving gear 312 to rotate, so that the driving gear 312 is engaged with the transmission gear 313 to control the rotation of the screw rod 321. When the screw rod 321 rotates, the moving block 33 will be driven to move. Since the moving block 33 is fixedly connected to the linkage block 4, and the linkage block 4 moves inside the mounting seat 32, the moving block 33 will be controlled to move stably along a straight line, and the push plate 331 will be driven to move. The push plate 331 moves forward and squeezes and pushes the outer surface of the product.

[0039] In the process of pushing the product, the two ends of the product will move. The device installs an elastic block on the inner side of the clamping plate 7 so that the two ends of the clamping plate 7 can have a certain amount of movable space. Under the continuous push of the pushing plate 331, the product can bend.

[0040] In actual processing, the bending degree of the product will be controlled according to production needs, so as to adjust the length of the connecting rod 14 extending out of the hollow cylinder 13, control the connecting rod 14 to retract or extend inside the hollow cylinder 13, and stably connect the connecting rod 14 to the hollow cylinder 13 through the axle pin, so as to adjust the position of the adjusting plate 122, control the position of the adjusting plate 122 to control the bending degree of the product, and set the adjusting plate 122 on the outside of the product. When the product is pushed and bent, the adjusting plate 122 will be squeezed, and a pressure sensor 123 is installed on the adjusting plate 122. When the adjusting plate 122 is squeezed, the pressure sensor 123 will be squeezed. When the pressure sensor 123 detects the presence of pressure, the PLC controller 15 will control the control motor 31 to stop working, and control the motor 31 to reverse, and restore the push plate 331 to its initial position, so that the product can be extracted from one side to complete the operation.

[0041] It should be noted that the control motor 31, pressure sensor 123 and PLC controller 15 are devices or equipment existing in the prior art, or are devices or equipment that can be implemented in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
