[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides a positioning fixture for processing lightweight unmanned aerial vehicle (UAV) wings, comprising:

[0027] The support mechanism 100 includes a support base 101, a support column 102 fixedly connected to the top of the support base 101, a worktable 103 welded to the top of the support column 102, and a triangular support block 104 fixedly connected to the top side of the worktable 103.

[0028] The positioning mechanism 200 includes a positioning component 201 welded to the top of the workbench 103, an adjustment component 202 fixedly connected to the inner surface of the triangular support block 104, and a clamping component 203 disposed at the bottom of the adjustment component 202.

[0029] Specifically, the bearing mechanism 100 is stably connected to the worktable 103 through the bearing seat 101, the support column 102, and the triangular support block 104 to enhance the overall rigidity, which can stably bear the working load; in the positioning mechanism 200, the positioning component 201 realizes basic positioning, the adjustment component 202 relies on the structural support of the triangular support block 104 to flexibly adjust the clamping position, and the bottom clamping component 203 can accurately fix the workpiece.

[0030] Furthermore, the positioning component 201 includes a bottom shell 201a, a fixing slot 201b fixedly connected to the bottom of the inner cavity of the bottom shell 201a, and a first double-ended motor 201c disposed in the inner cavity of the fixing slot 201b; the positioning component 201 also includes a first lead screw 201d adapted to be installed at the output end of the first double-ended motor 201c, a fixing arm 201e sleeved on the surface of the first lead screw 201d, and a silicone pad 201f fixedly connected to the inner surface of the fixing arm 201e.

[0031] Preferably, the bottom shell 201a and the fixed groove block 201b form a stable base, and the first double-ended motor 201c drives the first lead screw 201d to achieve precise power transmission, enabling the fixed arm 201e to move and adjust its position flexibly; while the silicone pad 201f on the inner surface of the fixed arm 201e not only enhances the friction with the workpiece and prevents displacement, but also avoids damage caused by hard contact, thereby ensuring accurate and stable workpiece positioning and effectively improving the reliability and safety of the operation.

[0032] It should be noted that the adjustment assembly 202 includes an adjustment post 202a disposed on the inner surface of the triangular support block 104, a limiting groove 202b formed on the surface of the adjustment post 202a, and a drive motor 202c fixedly connected to the top of the adjustment post 202a; the adjustment assembly 202 also includes a drive shaft 202d adapted to be installed at the output end of the drive motor 202c, an adjustment plate 202e sleeved on the surface of the drive shaft 202d, a fixing plate 202f fixedly connected to the top of the adjustment plate 202e, an adjustment shaft 202g welded to the inner surface of the fixing plate 202f, and an adjustment shaft 202g sleeved on the adjustment shaft 202c. The 2g surface has an adjustment block 202h; the clamping assembly 203 includes a connecting block 203a disposed at the bottom of the adjustment block 202h, a clamping box 203b fixedly connected to the bottom of the connecting block 203a, a second double-ended motor 203c fixedly connected to the inner cavity of the clamping box 203b, and a second lead screw 203d adapted to be installed at the output end of the second double-ended motor 203c; the clamping assembly 203 also includes a sleeve 203e sleeved on the surface of the second lead screw 203d, a limiting rod 203f snapped into the end of the sleeve 203e, and a clamping claw 203g welded to the surface of the limiting rod 203f.

[0033] The adjusting column 202a and the limiting groove 202b provide stable support and guidance. The drive motor 202c drives the adjusting plate 202e to adjust its position up and down through the drive shaft 202d. In the clamping assembly 203, the second double-end motor 203c drives the second lead screw 203d, so that the sleeve 203e slides smoothly along the limiting rod 203f, and accurately controls the opening and closing of the clamping claw 203g, which can adapt to the fixing requirements of workpieces of different specifications. The various structures are closely connected, allowing the equipment to flexibly cope with complex working conditions and ensure efficient and stable operation.

[0034] During use and operation, the support base 101, support column 102, and worktable 103 of the bearing mechanism 100 provide a stable foundation, and the triangular support block 104 enhances the overall rigidity. In the positioning assembly 201, the first double-ended motor 201c drives the first lead screw 201d to rotate, causing the fixed arm 201e to move up and down along the lead screw. The silicone pad 201f adheres to the wing surface to complete the basic positioning. The adjusting column 202a and the limiting groove 202b provide stable support and guidance. The drive motor 202c drives the adjusting plate 202e to achieve up and down adjustment through the drive shaft 202d. The second double-ended motor 203c of the clamping assembly 203 drives the second lead screw 203d. The sleeve 203e slides along the lead screw with the assistance of the limiting rod 203f, causing the clamping claw 203g to open and close, thereby achieving precise clamping and fixing of the wing to meet different processing requirements.

[0035] In summary, the triangular support block 104 in the bearing mechanism 100 reinforces the worktable 103, providing a stable processing plane; the first double-ended motor 201c of the positioning component 201 works with the first lead screw 201d to drive the fixed arm 201e to move along the track, and the silicone pad 201f achieves wing positioning; the drive motor 202c in the adjustment component 202 rotates the drive shaft 202d, controlling the adjustment block 202h to change the clamping height; the second double-ended motor 203c of the clamping component 203 drives the second lead screw 203d, driving the housing 203e and the limit rod 203f, so that the clamping claw 203g can be adjusted in spacing to adapt to wings of different sizes; the overall structure is simple and lightweight, solving the problems of limited adjustment and bulky equipment in traditional tooling.
