[0006] A kind of robot positioning and grabbing mechanism about fan blade, including lower pressure positioning plate, lower pressure positioning plate is fixed on mechanical hand, lower pressure positioning plate end is provided with positioning hole, positioning hole is matched with the flange of fan blade connecting port, lower pressure positioning plate bottom is fixedly installed with jaw cylinder, jaw cylinder output end is installed with jaw, jaw is driven by jaw cylinder and clamped and loosened, jaw is corresponding to the part of fan blade connecting plate.

[0007] As preferred, the lower pressure positioning plate is fixedly installed on the mechanical hand by fixed joint with bolt.

[0008] As preferred, the jaw clamping side is provided with clamping groove, and the clamping groove is matched with the fan blade connecting plate part.

[0009] As preferred, a plurality of parallelly distributed installation positioning waist round holes are arranged on the lower pressure positioning plate, for fixedly installing the jaw cylinder by bolt.

[0010] As preferred, the mechanical hand is a three-axis walking mechanical hand.

[0011] The utility model has the advantages that the utility model discloses a kind of robot positioning and grabbing mechanism about fan blade, is specially used for the robot positioning and grabbing of cross-flow fan blade, fan blade is grabbed and the position precision of taking and placing, avoid slip, ensure product quality. DRAWING DESCRIPTION

[0012] Figure 1 It is a kind of structural schematic diagram of prior whole cross-flow fan blade.

[0013] Figure 2 This is a schematic diagram of the structure of this utility model;

[0014] In the diagram: 1. Cylinder, 2. Connecting plate, 3. Flange, 4. Fan blade, 5. Gripper, 6. Gripper cylinder, 7. Pressing positioning plate, 8. Fixed joint, 9. Robotic arm, 10. Mounting positioning oval hole, 11. Grip groove, 12. Positioning hole. Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0016] Example: Figure 2 As shown, a robot positioning and gripping mechanism for a fan blade includes a pressing positioning plate 7, which is fixed on a robotic arm 9. The pressing positioning plate has a positioning hole 12 at its end, which engages with the flange of the fan blade connection port. A gripper cylinder 6 is fixedly installed at the bottom of the pressing positioning plate, and a gripper 5 is installed at the output end of the gripper cylinder. The gripper is driven by the gripper cylinder to clamp and release, and the gripper correspondingly grips the fan blade connection plate portion.

[0017] The downward positioning plate is fixedly mounted on the robotic arm with bolts via the fixing joint 8. The gripper clamping side is provided with a clamping groove 11, which mates with the fan blade connecting plate.

[0018] The lower positioning plate has multiple parallel mounting and positioning oblong holes 10 for fixing the gripper cylinder with bolts. The robot is a three-axis walking robot.

[0019] When this utility model is used, the positioning hole of the pressing positioning plate is first matched with the flange of the fan blade connection port by a three-axis walking robot. Then, the gripper cylinder is started to drive the gripper to clamp. The gripper clamps the fan blade connection plate part through the clamping groove, so that the fan blade is grasped and placed in a precise position, avoiding slippage and ensuring product quality.

[0020] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
