Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The following will be combined Figure 1-Figure 5 The blade two-side positioning device of the embodiment of the utility model is described in detail. Example

[0023] The blade two-side positioning device provided in the embodiment of the utility model refers to Figure 1 and Figure 5 As shown, it includes a base plate 1, a vertical plate 2 is welded on the base plate 1, a rotating cylinder 3 is fixedly installed on the upper part of the vertical plate 2, a mounting plate 4 is fixedly installed on the rotating shaft of the rotating cylinder 3, a connecting plate 5 is fixedly installed on the mounting plate 4, a transverse plate 6 is welded on the connecting plate 5, a blade front positioning component 7 is arranged on the upper surface of the transverse plate 6, and a blade back positioning component 8 is arranged on the lower surface of the transverse plate 6. When processing aviation blades, this structure can position and fix the blades through the blade front positioning component 7, thereby facilitating the processing of the front side of the blades. When the processing of the front side of the blades is completed, the rotating cylinder 3 is started to drive the mounting plate 4 to rotate 180 degrees, and the mounting plate 4 will drive the transverse plate 6 on the connecting plate 5 to rotate 180 degrees, thereby turning the blade back side positioning component 8 to the top, and then the blade back side positioning component 8 is used to position and process the back side of the blade.

[0024] It should be noted that the above-mentioned rotary cylinder 3 is of high precision and can rotate 180 degrees.

[0025] refer to Figure 1 , Figure 2 and Figure 3As shown, the blade front positioning assembly 7 includes four brackets 9, and a positioning block 10 is provided on the top of the bracket 9. The positioning block 10 is provided with a positioning groove 11 that matches the arc surface of the back side of the blade, and each positioning block 10 is installed with a suction cup 12 at the contact surface with the back side of the blade. This structure uses the positioning block 10 on the bracket 9 to support the blade facing up, and uses the positioning groove 11 to make the positioning block 10 fit the back side of the blade, so as to ensure stable support. When the blade facing up is placed, the personnel starts the vacuum generator to make the suction cup 12 generate vacuum, so as to suck the back side of the blade, so as to stably fix the blade on the blade front positioning assembly 7, so as to ensure the stability of the processing of the front side of the blade. When unloading after the later processing is completed, the personnel only needs to start the vacuum generator to make the suction cup 12 blow back, and then stop the vacuum state, and then the personnel can easily remove the blade.

[0026] refer to Figure 1 , Figure 2 river Figure 4 As shown, the blade back side positioning assembly 8 includes four brackets 13, and the top of the brackets 13 is provided with positioning blocks 14, and the positioning blocks 14 are provided with positioning grooves 15 that match the arc surface of the front side of the blade. Each positioning block 14 is installed with a suction cup 16 at the contact surface between the front side of the blade and the positioning block 14. This structure uses the positioning blocks 14 on the brackets 13 to support the blades with the back side facing upward, and uses the positioning grooves 15 to make the positioning blocks 13 fit the front side of the blade, thereby ensuring stable support. When the blades with the front side facing upward are placed, the personnel starts the vacuum generator to make the suction cups 16 generate vacuum, thereby sucking the front side of the blade, so that the blades are stably fixed on the blade back side positioning assembly 8, thereby ensuring the stability of the processing of the back side of the blade. When unloading after the later processing is completed, the personnel only needs to start the vacuum generator to make the suction cups 16 blow back, and then stop the vacuum state. At this time, the personnel can easily remove the blades.

[0027] refer to Figure 1 and Figure 5 As shown, positioning bars 17 are fixedly mounted on the upper and lower surfaces of the transverse plate 6. When placing blades, personnel can use the positioning bars 17 to position and release the blades to the left and right, so that the placement personnel can quickly and accurately place the blades in place.

[0028] refer to Figure 2 river Figure 5 As shown, a locking cylinder 18 is fixedly connected to the lower part of the vertical plate 2, and a locking pin 19 is fixedly installed at the end of the piston rod of the locking cylinder 18. Locking holes 20 are provided on the upper and lower sides of the mounting plate 4, and the locking pin 19 is adapted to be plugged into the locking hole 20. This structure utilizes the locking cylinder 18 to drive the locking pin 19 to be inserted into the locking hole 20, so that the position of the horizontal plate 6 can be fixed during blade processing, thereby avoiding displacement caused by processing vibration and ensuring the processing accuracy of the blade.

[0029] refer to Figure 3 As shown, a suction cup embedding groove 21 is provided at the contact surface between the positioning block 10 and the reverse side of the blade, and the suction cup 12 is embedded in the suction cup embedding groove 21. This structure utilizes the suction cup embedding groove 21 to prevent the suction cup 12 from protruding from the contact surface between the positioning block 10 and the blade.

[0030] refer to Figure 4 As shown, a suction cup embedding groove 22 is provided at the contact surface between the positioning block 14 and the front face of the blade, and the suction cup 16 is embedded in the suction cup embedding groove 22. This structure utilizes the suction cup embedding groove 22 to prevent the suction cup 16 from protruding from the contact surface between the positioning block 14 and the blade.

[0031] refer to Figure 1 As shown, reinforcing ribs 23 are provided at the connection between the connecting plate 5 and the transverse plate 6. This structure utilizes the reinforcing ribs 23 to improve the connection strength between the connecting plate 5 and the transverse plate 6 and the bearing capacity of the connection.

[0032] The implementation principle of the blade two-side positioning device of the embodiment of the present application is as follows: when in use, the blade facing up is placed on the positioning block 10 on the bracket 9 for support and support. During the placement, the positioning lever 17 can position the front and rear positions of the blade. When the blade facing up is placed on the positioning block 10, the positioning groove 11 can make the positioning block 10 fit the back side of the blade to ensure stable support and position the left and right positions of the blade at the same time. When the blade facing up is placed, the personnel starts the vacuum generator to make the suction cup 12 generate vacuum, thereby sucking the back side of the blade, so that the blade is stably fixed on the blade front positioning component 7, thereby ensuring the stable processing of the front side of the blade, and the later processing is completed. During the rear unloading, the personnel only need to start the vacuum generator to make the suction cup 12 back-blown, and then stop the vacuum state. At this time, the personnel can easily remove the blade, and then start the locking cylinder 18 to retract, so that the locking pin 19 disengages from the locking hole 20, and then start the rotating cylinder 3 to drive the mounting plate 4 to rotate 180 degrees. The mounting plate 4 will drive the cross plate 6 on the connecting plate 5 to rotate 180 degrees, thereby turning the blade reverse positioning component 8 to the top, and then start the locking cylinder 18 in the reverse direction to drive the locking pin 19 to insert into the locking hole 20, and then the personnel can place the blade with the reverse side facing up on the positioning block 2 14 of the reverse positioning component 8 similar to the front positioning component 7 for processing, thereby realizing the positioning processing of both sides of the blade.
