TECHNICAL FIELD
[0001] The utility model relates to panel processing equipment technical field, especially an aviation aluminum alloy tail wing rib plate grooving tool. BACKGROUND
[0002] The rib plate is the transverse force skeleton of the wing, which is consistent with the shape of the aircraft airfoil, and is mainly used for supporting the skin of the aircraft wing and maintaining the profile shape of the wing. It is a chordal component that maintains the wing surface shape and transmits local aerodynamic load in the wing surface structure. With the continuous development of aviation technology, the design and manufacturing of aircraft wing rib plates are also constantly innovating. The existing wing ribs are mainly made of forged aluminum alloy, which has the advantages of light weight, high load capacity, high rigidity, etc. In order to further reduce the weight of the rib plate, grooves can be opened on it. The existing grooving method is mostly flat, that is, the wing plate is directly placed flat on the workbench for grooving. This method requires a large pressure on the wing plate, which can easily cause the wing plate to deform under pressure. Because the wing plate is subject to the profile shape of the wing, it is mostly irregular in shape, so it is not easy to design the fixture when clamping. Therefore, it needs to be improved. SUMMARY

[0005] Preferably, the output end of the drive motor is connected with the drill bit through a shaft coupling and a speed reducer in sequence.
[0006] Preferably, a shock absorber is arranged at the connection between the supporting plate and the rack.
[0007] Preferably, the edge of the groove seat is provided with a sliding seat, the inner side of the groove is provided with a sliding rail, and the sliding seat is movably clamped on the sliding rail.

[0015] As Figures 1 to 3As shown in the figure, the aviation aluminum alloy tail wing rib slotting tooling includes a rack 1, a driving motor 2, a drill bit 3, a screw rod assembly 4, a platform 5 and a workpiece clamping piece 6, the driving motor 2 is installed on a supporting plate 11 of the rack 1, the output end of the driving motor 2 is connected with the drill bit 3, drives the drill bit 3 to rotate to groove the surface of the workpiece, the platform 5 is movably installed on the screw rod assembly 4, the direction in which the screw rod assembly 4 drives the platform 5 to displace is perpendicular to the axial direction of the drill bit 3, the workpiece clamping piece 6 includes a groove seat 61 and a plurality of supporting air cylinders 62, the side of the platform 5 away from the driving motor 2 is provided with a groove 51, the edge of the groove seat 61 is connected with the inner side of the groove 51, the plurality of supporting air cylinders 62 are installed side by side on the side of the groove seat 61 away from the platform 5, and the output end of the supporting air cylinder 62 is movably inserted into a machining groove 611 in the groove seat 61. Specifically, in the embodiment, the output end of the driving motor 2 is connected with the drill bit 3, drives the drill bit 3 to rotate, and the surface of the workpiece (not shown in the figure) can be drilled and grooved. During the operation, the workpiece is vertically placed in the groove seat 61, during the machining, the drill bit 3 penetrates through the hollow part of the groove seat 61 and contacts the surface of the workpiece to drill the workpiece. When grooving is needed, the platform 5 is driven to displace by the screw rod assembly 4, and then the workpiece clamping piece 6 is driven to displace, so that the workpiece is displaced, and then the drill bit 3 processes a horizontal groove on the surface of the workpiece. During the machining process, the drill bit 3 inevitably applies a lateral force to the workpiece. In order to provide lateral support for the workpiece, the supporting air cylinder 62 is installed on the groove seat 61, and the supporting air cylinder 62 provides a lateral support for the workpiece, so that the workpiece always maintains a vertical posture and does not tilt. The workpiece is carried by the workpiece clamping piece 6, and the drill bit 3 performs machining operation on the side surface of the workpiece, so that the workpiece does not need to be placed horizontally for machining, and a complex clamping tooling does not need to be designed for the workpiece with an irregular shape, thereby effectively reducing the tooling cost.
[0016] As shown in the figure, Figure 1 , 3 the output end of the driving motor 2 is connected with the drill bit 3 in sequence through a shaft coupling 21 and a speed reducer 22, the shaft coupling 21 can reduce vibration and buffering, and has the function of overload protection, and the speed reducer 22 increases the output torque through speed reduction, and the torque output ratio is calculated according to the motor output multiplied by the speed reduction ratio.
[0017] As shown in the figure, Figure 3 the connecting part of the supporting plate 11 and the rack 1 is provided with a shock absorber 12, thereby reducing the influence of the driving motor 2 on the rack 1 during operation.
[0018] As shown in the figure, Figures 1 to 2As shown, the edge of the groove seat 61 is provided with a sliding seat 612, the inner side of the slot 51 is provided with a sliding rail 511, and the sliding seat 612 is movably clamped on the sliding rail 511. Specifically, the sliding seat 612 cooperates with the sliding rail 511, so that the groove seat 61 can displace in the slot 51, thereby adjusting the distance between the workpiece belt machining surface and the drill bit 3, and a guide rail clamp is arranged in the sliding seat 612, when the groove seat 61 is displaced to a specified position, the guide rail clamp can lock the sliding rail 511, so as to avoid that the groove seat 61 directly retreats under force during machining.
[0019] The above-mentioned embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
