DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] In this embodiment, if Figure 1-Figure 5 As shown, a rotor fan blade welding device includes a base plate 101, and connecting columns 102 are symmetrically arranged on both sides of the base plate 101. The connecting columns 102 play the role of supporting the adjustment mechanism 300 to ensure the normal use of the device, and also include a fixing mechanism 200 and an adjustment mechanism 300. The fixing mechanism 200 is arranged on one side of the connecting column 102 and is used to fix the rotating shaft of the rotor. The adjustment mechanism 300 is arranged between the connecting columns 102 and is used to dock the fan blade with the rotor. Before the rotor fan blade welding device starts to be used, the rotor is first fixed by the fixing mechanism 200, and then the fan blade is fixed by the docking assembly, and the second motor 304 is started so that the fan blade can contact the rotor, so that the device enters a ready-to-use state;

[0027] Among them Figure 2 and Figure 3 As shown, the fixing mechanism 200 includes a first motor 201 arranged inside the connecting column 102. When the first wind blade is welded, the first motor 201 is started to drive the first gear 202 to rotate, and then drive the second gear 203 to rotate, thereby driving the rotor to rotate, which is convenient for the welding operation of the second wind blade. The output end of the first motor 201 extends to the outside of the connecting column 102 and is fixedly connected with the first gear 202. The upper part of the first gear 202 is meshed and connected with the second gear 203. The second gear 203 is rotatably connected to the connecting column 102. An electric push rod 204 is fixedly arranged on one side of the second gear 203. The electric push rod 204 can drive the rotor to move, which is convenient for cooperating with the adjustment mechanism 300. A mounting block 205 is connected to the output end of the electric push rod 204. A groove is opened on the surface of the mounting block 205. The groove is used to place the rotor shaft. A fastening bolt is arranged on one side of the mounting block 205. The rotor shaft is placed in the groove, and then the fastening bolt is tightened to limit the rotor.

[0028] Among them Figure 2-Figure 5 As shown, the adjustment mechanism 300 includes a horizontal plate 301, a slide groove 302 is provided on the lower surface of the horizontal plate 301, and a screw rod 303 is rotatably connected inside the slide groove 302. One end of the screw rod 303 extends to the outside of the horizontal plate 301 and is connected to a second motor 304. The second motor 304 is started to drive the screw rod 303 to rotate, thereby causing the slider 305 to move along the direction of the slide groove 302, thereby causing the wind blade to correspond to the position of the rotor, so as to adapt to wind blades of different sizes. The outer side of the screw rod 303 is threadedly connected to the slider 305, and the lower end of the slider 305 is fixedly installed with a lifting push rod 306, which can drive the wind blade to move, so as to cooperate with the fixing mechanism 200. The output end of the lifting push rod 306 is fixedly installed with a rotating assembly, and the lower end of the rotating assembly is connected with a docking assembly. Through the docking assembly and the rotating assembly, the wind blade and the rotor are attached together, so as to facilitate welding work.

[0029] Among them Figure 4 As shown, the rotating assembly includes a fixed seat 307, a chamber is arranged inside the fixed seat 307, and a movable ball 308 is arranged inside the chamber. The movable ball 308 enables the direction of the wind blade to be freely changed. The lower end of the movable ball 308 is connected to the docking assembly. A fixing bolt is arranged on one side of the fixed seat 307. After the wind blade is fitted with the rotor, the fixing bolt is tightened to fix the position of the wind blade, thereby increasing the overall practicality of the device.

[0030] Among them Figure 4 and Figure 5 As shown, the docking assembly includes symmetrically arranged connecting blocks, the internal threads of the connecting blocks are connected to a rotating rod 309, and a clamping plate 310 is fixedly arranged on the outer side of the rotating rod 309. The size of the clamping plate 310 is smaller than the distance between the two connecting blocks, so that when the rotating rod 309 rotates, the connecting block cannot affect the rotation of the clamping plate 310. Limiting blocks are arranged at both ends of the rotating rod 309 to ensure the normal use of the device;

[0031] Among them Figure 1 As shown, a welding gun 103 is fixedly provided at the upper end of the bottom plate 101. When the wind blades and the rotor are fixed in position, the user uses the welding gun 103 to weld the connection between the wind blades and the rotor;

[0032] Example 2

[0033] The difference from Example 1 is that Figure 6 As shown, the lower end of the bottom plate 101 is symmetrically provided with support columns 104, which play the role of supporting the rotor blade welding device, making it easy to move and increasing the overall use effect of the device;

[0034] Among them Figure 6 As shown, an anti-skid pad is provided at the lower end of the clamping plate 310. The anti-skid pad is made of elastic rubber material, which increases the contact area between the clamping plate 310 and the wind blade, improves the friction effect, and further enhances the fixing ability.

[0035] When in use, place the rotor shaft into the groove, fix the rotor by tightening bolts, place the wind blade between the two clamping plates 310, rotate the rotating rod 309, and make the lower ends of the two clamping plates 310 approach each other, so as to fix the wind blade, start the second motor 304, move the slider 305 and the wind blade to the top of the rotor, rotate the movable ball 308 through the cooperation of the lifting push rod 306, so that the lower end of the wind blade can fit with the rotor, and then tighten the fixing screw brush. The user holds the welding gun 103 to weld the wind blade. After welding the first wind blade, start the first motor 201 to drive the first gear 202 to rotate, and then drive the second gear 203 and the rotor to rotate, and start the welding operation of the next wind blade, which is more practical.

[0036] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
