[0002] In a broad sense, any device used to quickly, conveniently and safely install workpieces in any process in the process can be called a fixture, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing workpieces on machine tools, in order to make the surface of the workpiece meet the technical requirements such as size, geometry and relative position accuracy with other surfaces specified in the drawings, the workpiece must be installed (positioned) and clamped (clamped) before processing. The fixture is usually composed of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), an indexing device (to enable the workpiece to complete the processing of several stations in one installation, there are two types of rotary indexing devices and linear motion indexing devices), connecting elements and a clamping body (fixture base), etc. The fan blades need to be polished in the wake or before welding to deal with the burrs. The fan blades are not easy to fix during grinding, which is not convenient for grinding.

[0046] The rotating disk 8 installed between the connecting parts 6 is connected to the lower fixed block 10 through the upper fixed block 9. The movable clamping plate 11 installed between the two sets of rotating disks 8 can assist in clamping the fan blades to be repaired and polished. At the same time, the hollow groove 12 opened on the lower fixed block 10 can be passed through by the anti-collision clamping block 17 installed at the top of the lifting rod 16. The anti-collision clamping block 17 passing through the hollow groove 12 can abut and clamp the bottom of the fan blade to ensure the stability of the fan blade.

[0047] The lifting mechanism 3 includes a support frame 13, on which a lifting beam 14 is horizontally installed. A lifting chain hook 15 is provided on the lifting beam 14, and the lifting chain hook 15 is connected to the connecting part 6.
