In order to achieve the purpose, the rapid marking device for assembling the centrifugal fan blade comprises a central column, a thrust disc, a top device, a soft belt, a plurality of main connecting rods, a plurality of auxiliary connecting rods, a plurality of blades and a plurality of auxiliary supports;
the thrust disc is sleeved on the central column, and one main connecting rod corresponds to one blade, one auxiliary support and one auxiliary connecting rod; the upper end of each main connecting rod is movably connected with the thrust disc, the lower end of each main connecting rod is movably connected with one end of the corresponding blade, one end of each auxiliary support is movably connected with the other end of the corresponding blade, the other end of each auxiliary support is movably connected with the corresponding main connecting rod, the top device is fixed at the lower end of the central column, one end of each auxiliary connecting rod is movably connected with the middle part of the corresponding main connecting rod, and the other end of each auxiliary connecting rod is movably connected with the top device.
The device also comprises a soft belt, and the soft belt is hung on each blade.
The blades are connected with the soft belt through hooks.
The hook is an S-shaped metal hook.
All the main connecting rods are evenly distributed along the circumferential direction.
All the blades are uniformly distributed along the circumferential direction.
All the auxiliary connecting rods are uniformly distributed along the circumferential direction.
The auxiliary supports are uniformly distributed along the circumferential direction.
The invention has the following beneficial effects:
when the rapid marking device for assembling the centrifugal fan blades is operated, all the blades move outwards only by pressing the thrust disc downwards, and when the thrust disc moves to the maximum stroke, marking can be carried out on the positions of the blades at the moment, so that the rapid marking device is simple and convenient to operate and has strong practicability. It should be noted that the invention cancels the procedures of marking and finding the base point of the blade position, reduces the measuring workload, improves the working efficiency, avoids the problems of rework and the like caused by angle reading errors or marking operation errors, and can save labor and working hours while ensuring the marking accuracy.
