Aerospace tooling fixtures are used in the aerospace field to manufacture high-precision parts, such as turbine blades and bearings. Their application can significantly improve production efficiency and product quality.
[0003] Currently available aerospace tooling fixtures are unable to quickly and securely clamp and fix aerospace components, resulting in reduced processing efficiency for these components. Utility Model Content
[0004] The purpose of this invention is to provide a vacuum chuck fixture for aerospace components, which can improve processing efficiency while ensuring and meeting the quality requirements of aerospace components.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] The first aspect of this utility model is to provide a vacuum chuck tooling fixture for aerospace component products, including a vacuum generating assembly, a fixture body and a gas pipeline assembly.
[0007] The main body of the clamp is a modular structure welded from integrated modular steel structure, including a bottom support frame and a flat suction cup horizontally fixed to the top of the support frame. The upper surface of the flat suction cup has an adsorption area, and a sealing strip is provided at its edge. The adsorption area has high-density and crisscrossing suction grooves, and the bottom of the suction grooves has multiple suction holes that penetrate the flat suction cup. The multiple suction holes are distributed in a "W" shaped curve on one side of the upper surface of the flat suction cup.
[0008] The gas pipeline assembly is used to connect the suction port and the vacuum generating assembly, including a gas port concentrator and distributor and a suction line. The gas port concentrator is installed between the bottom support frame and the flat suction cup, and has multiple interconnected main suction ports and branch suction ports.
[0009] The fixture body and the gas pipeline assembly are configured as one or more groups, with the fixture bodies arranged side by side in sequence in multiple groups, and the gas channel collectors and distributors connected in series in sequence.
[0010] Furthermore, the vacuum generating assembly includes a vacuum pump and a vacuum tube, one end of which is connected to the vacuum pump, and the other end is provided with a first connector that matches the main suction port.
[0011] Furthermore, the vacuum generating assembly also includes a gas storage tank connected to the vacuum pump.
[0012] The gas storage tank can effectively alleviate the fatigue stress generated by the vacuum pump during long-term operation, and at the same time achieve the optimized operation of the system through energy storage input and output.
[0013] Furthermore, the vacuum pump is equipped with a vacuum pump flow controller.
[0014] The vacuum pump is equipped with a vacuum pump flow controller, which can stabilize and extend the service life of the pump by precisely controlling the flow and pressure while ensuring the normal operation of the vacuum pump, thereby enabling the vacuum pump and the gas storage tank to work normally within the effective range.
[0015] Furthermore, the main intake port includes a first main intake port located at the front end of the air passage hole collector and a second main intake port located at the rear end of the air passage hole collector and distributor, and the branch intake ports are located on the left and right sides of the air passage hole collector and distributor.

[0017] Furthermore, the fixture body and the gas pipeline assembly are configured in multiple groups. The first main intake port of the first gas channel collector and distributor is connected to the vacuum tube. The second main intake port of the last gas channel collector and distributor is detachably sealed with a plug. The intake pipeline includes a main intake pipeline and branch intake pipelines. The main intake pipeline is used to connect the second main intake port of the previous gas channel collector and distributor to the first main intake port of the next gas channel collector and distributor. The branch intake pipelines are located at the branch intake ports. The other end of each branch intake pipeline is provided with a second connector that matches the intake through hole and is connected to the intake through hole through the second connector.
[0018] Furthermore, the air intake groove has a U-shaped bottom.
[0019] The bottom of the air intake groove is U-shaped, which provides strong sealing performance and reduces the risk of workpiece processing.
[0020] Furthermore, an air valve is installed on the main intake line.
[0021] Furthermore, a pressure gauge is provided on the gas channel manifold.
[0022] Compared with the prior art, the present invention has at least the following beneficial effects:
[0023] The vacuum chuck fixture for aerospace components provided by this utility model is suitable for machining critical parts. By clamping and positioning the workpiece, the precision requirements of the product are guaranteed, and the workpiece is undamaged during processing. This vacuum chuck fixture meets the equipment's suction force requirements for product processing, and the fixture and workpiece can be quickly, accurately, and reliably attached. The flat chuck has multiple suction holes arranged in a "W" curve, which not only evenly distributes suction force, making the workpiece more stable during processing and reducing loosening due to insufficient local suction force, but also better fits irregularly shaped or uneven workpieces, ensuring effective vacuum suction at different positions. Furthermore, multiple suction holes can simultaneously suction multiple workpieces, or achieve more efficient clamping on a single workpiece, reducing clamping time and further improving production efficiency.
