[0028] As shown in Figures 1-7 In one embodiment, an impeller welding device for an environment-friendly and energy-saving fan is provided, which comprises a workbench 1, a positioning seat 101 is installed at the upper end of the workbench 1, a shaft sleeve 102 is stored in the positioning seat 101, a positioning assembly 2 is installed at the upper end of the workbench 1, the positioning assembly 2 comprises a guide frame 201, a sliding seat 202, an inclined frame 203, a supporting rod 204, a telescopic cylinder 205 and a positioning rod 206, a plurality of guide frames 201 are equidistantly installed on the upper end of the workbench 1, a plurality of sliding seats 202 are all slidingly connected to the circumferential surface of the guide frame 201, the inclined frame 203 is installed at the upper end of the sliding seat 202, the supporting rod 204 is installed on the surface of the inclined frame 203, the telescopic cylinder 205 is installed at both ends of the inclined frame 203, the positioning rod 206 is slidingly connected in the telescopic cylinder 205, the spring 207 is installed between the positioning rod 206 and the telescopic cylinder 205, and the blade 208 is clamped between the positioning rod 206 and the supporting rod 204.

[0029] In actual application, the blades 208 to be welded on the shaft sleeve 102 are placed in the inclined frame 203, one side of the blade 208 is supported by the supporting rod 204 in the inclined frame 203, the other side of the blade 208 is extruded by the positioning rod 206 through the action of the spring 207, and the blade 208 is fixed in position in cooperation with the supporting rod 204, and the position of the blade 208 is corrected at the same time. Then, the sliding seat 202 can be controlled to move inward by the action of the guide frame 201, so as to drive the blade 208 to be attached to the shaft sleeve 102. Then, the welding equipment outside can be used to weld the connection between the blade 208 and the shaft sleeve 102. After the welding of one side of the connection between the blade 208 and the shaft sleeve 102 is completed, the sliding seat 202 is controlled to slide and reset on the guide frame 201, so that the blade 208 is separated from the inclined frame 203. At this time, the blade 208 and the shaft sleeve 102 are already in a connected state, so the shaft sleeve 102 can be taken out of the positioning seat 101. Then, the shaft sleeve 102 and the blade 208 can be turned over, the other side of the shaft sleeve 102 is placed into the positioning seat 101, and the welding equipment outside can be used to weld the other side of the connection between the blade 208 and the shaft sleeve 102, so as to realize the welding effect of the blade 208. Not only can multiple blades 208 be positioned and spliced at the same time, but also the splicing angle position of the blade 208 is relatively accurate through the action of the positioning assembly 2, so as to improve the efficiency and quality of impeller welding.

[0030] As Figure 6 And 7 As shown in the figure, in one embodiment, the inclined frame 203 is surface-mounted with a pair of support seats 209, and the vane 208 is located between the support seats 209, which are used to support and limit the upper and lower ends of the vane 208.

[0031] In actual application, when the vane 208 is placed in the inclined frame 203, the upper and lower sides of the vane 208 are limited in position by the support seats 209. Then the spring 207 pushes the positioning rod 206, which pushes one side of the vane 208, so that the vane 208 is attached to the support rod 204 and the support seats 209 on the upper and lower sides, thereby achieving the effect of correcting the position of the vane 208. When the vane 208 is attached to the shaft sleeve 102, the vane 208 can be spliced with the shaft sleeve 102, and then multiple vanes 208 can be welded with the shaft sleeve 102 in sequence, thereby improving the efficiency and quality of vane 208 welding.

A rotating shaft 302 is rotatably connected in the push rod 301, and a rotating block 303 is mounted on the circumferential surface of the rotating shaft 302. A clockwork spring 304 is connected between the rotating shaft 302 and the push rod 301, and the rotating block 303 is used to push the vane 208 to attach to the shaft sleeve 102.

[0033] In actual application, when the vane 208 is placed in the inclined frame 203, the rotating block 303 will block the entrance of the inclined frame 203, and the vane 208 will push the rotating block 303 to rotate in the push rod 301. When the vane 208 is placed in the inclined frame 203, the vane 208 is separated from the rotating block 303. Through the action of the clockwork spring 304, the rotating block 303 can be rotated and reset. Since the rotating block 303 can only rotate to one side, when the push rod 301 moves inward, the rotating block 303 will attach to one side of the vane 208 and push the vane 208 to move inward until one end of the vane 208 is attached to the shaft sleeve 102, thereby achieving the effect of controlling the splicing of the vane 208 and the shaft sleeve 102.

[0034] As Figure 2 And 3 As shown in the figure, in one embodiment, a rotating disc 305 is rotatably connected to the lower end of the workbench 1, a plurality of inclined grooves 306 are formed on the circumferential surface of the rotating disc 305, and a connecting shaft 307 is mounted on the lower end of each push rod 301. The connecting shaft 307 is located in the inclined groove 306 and is slidingly connected with the inclined groove 306.

[0035] In actual application, the embodiment of the present application controls the rotation of the rotating disc 305, so that the rotating disc 305 drives the chute 306 to change the position, the chute 306 drives the connecting shaft 307 to move the position, and the connecting shaft 307 drives the push rod 301 to slide in the sliding groove 3, so as to achieve the effect of moving the blade 208 inward, so that the blade 208 is tightly attached to the shaft sleeve 102, and the splicing of the blade 208 and the shaft sleeve 102 is completed.

[0036] As shown in the drawings, Figure 2 In one embodiment, the lower end of the workbench 1 is provided with a driving motor 308, the output end of the driving motor 308 is provided with a driving shaft 309, and the circumferential surface of the driving shaft 309 is fixedly connected with the rotating disc 305.

[0037] In actual application, the embodiment of the present application controls the rotation of the rotating disc 305, so that the rotating disc 305 drives the chute 306 to change the position, the chute 306 drives the connecting shaft 307 to move the position, and the connecting shaft 307 drives the push rod 301 to slide in the sliding groove 3, so as to achieve the effect of moving the blade 208 inward, so that the blade 208 is tightly attached to the shaft sleeve 102, and the splicing of the blade 208 and the shaft sleeve 102 is completed.

[0038] As shown in the drawings, Figure 4 In one embodiment, the surface of the push rod 301 is provided with a pull rod 4, the circumferential surface of the sliding seat 202 is provided with a sliding sleeve 401, the pull rod 4 is slidably connected with the sliding sleeve 401, and the circumferential surface of the pull rod 4 is provided with a plurality of limiting blocks 402.

[0039] In actual application, when the push rod 301 moves inward, the push rod 301 drives the pull rod 4 to move inward, the pull rod 4 drives the sliding sleeve 401 to move inward through one of the limiting blocks 402 arranged on the circumferential surface, the sliding sleeve 401 drives the sliding seat 202 to move inward, and the effect of driving the inclined frame 203 and the blade 208 to move inward synchronously is achieved. When the push rod 301 moves outward, the push rod 301 drives the pull rod 4 to move outward, the pull rod 4 drives the sliding sleeve 401 to move outward through another limiting block 402 arranged on the circumferential surface, the sliding sleeve 401 drives the sliding seat 202 to move outward, the sliding seat 202 drives the inclined frame 203 to move outward, and the blade 208 is separated from the inclined frame 203. Since the blade 208 is welded to the shaft sleeve 102 by the welding equipment at this time, the inclined frame 203 is separated from the blade 208, and the blade 208 is separated from the limiting of the inclined frame 203, so that the shaft sleeve 102 can be directly taken out of the positioning seat 101. After the welding is completed, the welded blade 208 can be directly taken out of the workbench 1.

[0040] As shown in the drawings, Figure 7 and 9As shown, in one embodiment, the positioning rod 206 is surface-mounted with a connecting rod 5, the connecting rod 5 is slidingly connected with the telescopic cylinder 205, one end of the connecting rod 5 away from the positioning rod 206 is mounted with a connecting frame 501, the upper end of the workbench 1 is mounted with a mounting frame 502, the surface of the mounting frame 502 is mounted with a driving block 503, the driving block 503 is slidingly connected with the connecting frame 501.

[0041] In actual application, when the tilt frame 203 moves to the periphery, the connecting frame 501 will be in contact with the driving block 503, then the driving block 503 will push the connecting frame 501 to move, the connecting frame 501 drives the connecting shaft 307 to move, the connecting rod 5 drives the positioning rod 206 to move, so that the positioning rod 206 is retracted into the telescopic cylinder 205, the distance between the positioning rod 206 and the supporting rod 204 is increased, and the subsequent blade 208 is facilitated to be placed into the tilt frame 203, when the blade 208 is placed into the tilt frame 203, the tilt frame 203 and the blade 208 are controlled to move to the inside, at this time, the connecting frame 501 will gradually be separated from the driving block 503, the supporting effect of the connecting frame 501 is removed, then under the action of the spring 207, the positioning rod 206 can be reset, and the blade 208 is pressed by the supporting rod 204, so that the position correction effect of the blade 208 is achieved.

[0042] As shown in Figure 8 and 10 As shown, in one embodiment, the upper end surface of the positioning seat 101 is provided with a plurality of mounting grooves 6, and the mounting grooves 6 are all mounted with suction cups 601.

[0043] In actual application, when the shaft sleeve 102 and the blade 208 are welded on one side, the tilt frame 203 is reset by moving to the periphery, at this time, the shaft sleeve 102 can be taken out from the positioning seat 101, and then the shaft sleeve 102 is placed into the positioning seat 101 after being turned over, then the suction cups 601 are controlled to operate, the shaft sleeve 102 is adsorbed on the surface of the suction cups 601, so that the shaft sleeve 102 is fixed in the positioning seat 101, and the position of the shaft sleeve 102 is prevented from moving, thereby affecting the welding of the other side of the connecting part of the shaft sleeve 102 and the blade 208.
