Description

Technical Field

[0001] This utility model relates to the field of drone fairing processing technology, specifically a drone air inlet fairing molding mold. Background Technology

[0002] A drone is an aircraft that can fly without human control. It has a wide range of applications, such as military, scientific research, and rescue. The shape design of a drone has a significant impact on its flight performance. Among them, the fairing is a shell used to reduce air resistance and protect internal equipment.

[0003] In the existing technology, the air intake fairing of drones needs to be shaped by a molding die during the production process. The current molding die usually places the workpiece between the upper and lower molds and then clamps and shapes the workpiece inside the mold. However, the current molding die usually lacks a positioning device, which makes it difficult to determine the position of the workpiece, resulting in an increase in the defect rate of the fairing.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-4 As shown, the present invention provides a UAV air inlet fairing shaping mold, including a U-shaped plate 1, and an auxiliary shaping mechanism 2 is provided on the inner side of the U-shaped plate 1;

[0025] The auxiliary shaping mechanism 2 includes an upper mounting plate 9 and a lower mounting plate 8. The upper mold 10 inside the upper mounting plate 9 and the lower mold 11 inside the lower mounting plate 8 fit together to press and shape the internal fairing. An adjusting screw 17 is rotatably connected to the rear end of the top wall of the upper mounting plate 9. A threaded plate 18 is threadedly connected to the upper part of the adjusting screw 17. During the rotation of the adjusting screw 17, the threaded plate 18 can move up and down. The threaded plate 18 is fixedly connected to the middle of the rear wall of the mounting frame 15. During the up and down movement of the threaded plate 18, the mounting frame 15 and its bottom components will move up and down. A bidirectional screw 19 is rotatably connected to the inner center of the frame 15. Threaded blocks 20 are threaded to both the left and right sides of the outer periphery of the bidirectional screw 19. Clamping parts 21 are fixedly connected to the bottom of each threaded block 20. During the rotation of the bidirectional screw 19, the two sets of clamping parts 21 move closer to each other to clamp the left and right sides of the fairing processing part. Then, the clamping parts 21 are moved upwards and clamped on the upper and lower sides by the cooperation of the upper mounting plate 9 and the clamping parts 21, thereby determining the position of the processing part. A knob 16 is rotatably connected to the left wall of the mounting frame 15, and the knob 16 is fixedly connected to the bidirectional screw 19.

[0026] The clamping member 21 is slidably connected to the left and right sides of the inner side of the connecting groove 14. The connecting groove 14 is located inside the rear side of the upper mounting plate 9, and the connecting groove 14 provides space for the clamping member 21 to move left and right and up and down.

[0027] The upper mounting plate 9 has an upper mold 10 on the front side of the middle section, and the lower mounting plate 8 has a lower mold 11 on the front side of the middle section. After the upper mold 10 and the lower mold 11 are attached, the cavity in the middle is the fairing shaping area.

[0028] Among them, the top plate 3 is fixedly connected to the top left and right sides of the U-shaped plate 1, and the cylinder 4 is fixedly connected to the middle of the top wall of the top plate 3. The operation of the cylinder 4 can drive the connecting rod 5 to move up and down.

[0029] Among them, the output end of the cylinder 4 is fixedly connected to the connecting rod 5, and the lower pressure plate 6 is fixedly connected through the lower part of the outer periphery of the connecting rod 5. The bottom end of the connecting rod 5 is provided with a positioning block 7, which can be inserted into the inside of the positioning tube 13 to determine the position of the upper mold 10 and the lower mold 11.

[0030] The top wall of the U-shaped plate 1 is fixedly connected to the left and right sides of the middle section, and the positioning tubes 13 are all fitted with the positioning block 7 with a clearance. The two sets of positioning tubes 13 can determine the position of the lower mounting plate 8.

[0031] Among them, the upper mounting plate 9 and the lower mounting plate 8 are provided with through holes 12 on the left and right sides of the middle part, and the through holes 12 are slidably connected to the connecting rod 5 and the positioning tube 13.

[0032] Working principle: When the fairing needs to be shaped, the through hole 12 inside the lower mounting plate 8 is engaged with the outside of the positioning tube 13 and the connecting rod 5 passes through the through hole 12 inside the upper mounting plate 9. With the cooperation of the positioning block 7 and the positioning tube 13, the positions of the upper mold 10 and the lower mold 11 are determined. Then, the workpiece is attached to the bottom wall of the upper mounting plate 9. Then, the knob 16 is turned. During the rotation of the knob 16, the bidirectional screw 19 is rotated. The rotation of the bidirectional screw 19 causes the clamping parts 21 on both sides to move closer to each other and clamp and fix the left and right sides of the rear end of the workpiece. Then, the adjusting screw 17 is turned to move the threaded plate 18 upward, which drives the workpiece to move upward, so that the workpiece is attached to the upper mold 10 and the position of the workpiece is determined. Finally, the cylinder 4 is started to perform the shaping operation on the workpiece.
