Due to the irregular shape of the fan blades, the clamping and processing is very difficult. The positioning tooling in the prior art has a poor clamping and positioning effect on the fan blades and cannot adapt to irregular fan blades. Both methods cannot guarantee the position of the center hole and the rest of the blade, which easily leads to deviations in the position of the processed center hole, low efficiency in machining the center hole and high scrap rate.

[0036] The utility model is further described in conjunction with the following embodiments.

[0037] Example 1.

[0038] like Figure 1-2 As shown, a fan blade processing and positioning tool comprises a working platform 1, a movable slide rail 2 is installed at the bottom of the working platform 1, four groups of movable slide grooves 3 are opened on the top of the working platform, two groups of blade positioning mechanisms 4 are movably installed in the movable slide grooves 3, and a blade mounting base 5 and an auxiliary support 6 are installed between the two groups of blade positioning mechanisms 4.

[0039] The movable slide rail 2 installed at the bottom of the work platform 1 can facilitate the movement of the entire workbench when clamping and positioning the fan blades to be processed. The two sets of blade positioning mechanisms 4 installed in the movable slide groove 3 opened on the work platform 1 can play a major role in clamping and fixing the fan blades. At the same time, the blade positioning mechanism 4 that is easy to adjust can increase the stability of clamping and positioning. The blade mounting base 5 and the auxiliary support are used to support the bottom end of the fan blades, thereby ensuring the positioning stability of the fan blades from multiple directions.

[0040] The blade positioning mechanism 4 includes two sets of sliding rods 7, a pushing block 8 is installed at the bottom of the sliding rod 7, and a moving plate 9 is installed at the top of the two sets of sliding rods. A clamping groove 10 is arranged on the moving plate 9, and a protruding block 11 is arranged at the top of the clamping groove 10. An arc extension groove 12 is arranged at one end of the clamping groove 10 close to the blade mounting base 5.

[0041] By operating the pushing block 8, the movable plate 9 is moved laterally in the movable slide groove 3. The clamping groove 10 on the movable plate 9 can clamp the fan blades stably. The arc extension groove 12 installed on the clamping groove 10 can be installed in coordination with the curvature of the fan blades to prevent damage to the fan blades due to clamping, and at the same time prevent the generation of gaps that affect the stability of the clamping.

[0042] Two groups of anti-collision pads 13 are arranged at the bottom of the blade mounting base 5 , and rigid springs 14 are installed on the anti-collision pads 13 .

[0043] Two groups of blind holes 15 are provided on the working platform 1 . The outer ends of the blind holes 15 are provided with limiting grooves 16 . The limiting grooves 16 fit with the anti-collision gaskets 13 . The interiors of the blind holes 15 are fixedly connected with rigid springs 14 .

[0044] The rigid spring 14 arranged in the blind hole 15 can be pressed down by the blade mounting base 5, and the rigid spring 14 can be compressed during the pressing process. At the same time, the limit groove 16 opened on the working platform 1 can fit with the anti-collision electric bar to prevent collision and fix the force point of the rigid spring 14 to prevent displacement during the extension and retraction process, thereby playing a buffering role for the blade mounting base 5.

[0045] A rubber block 17 is installed on the top of the auxiliary support 6, and a circular anti-collision groove 18 is opened on the rubber block 17. The auxiliary support 6 is installed parallel to the blade mounting base 5. The circular anti-collision groove 18 opened on the rubber block 17 can play a buffering role to prevent collision when the fan blades are loaded, and at the same time prevent damage to the fan blades when clamping and positioning.

[0046] The flexible interlayer 19 is evenly arranged inside the clamping groove 10, and the inner end of the clamping groove 10 is arc-shaped. The flexible interlayer 19 installed inside the clamping groove 10 can prevent the edge of the fan blade from being clamped and damaged, thereby maintaining stability and increasing safety.

[0047] During the production process, the fan blades to be processed are stably positioned and clamped by a positioning mechanism and a blade mounting base 5 installed on the working platform 1. At the same time, the two sets of blade positioning mechanisms 4 can be moved and clamped by a pushing block 8 installed at the bottom of the working platform 1. The rigid spring 14 installed between the blade mounting base 5 and the working platform 1 can assist in clamping and supporting the fan blades to be processed, and cooperate with the clamping grooves 10 set at both ends to improve the stability of fan blade processing.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
