Description

Technical Field

[0001] The present invention relates to the technical field of impeller welding, and more particularly to an impeller welding device for an environmentally friendly and energy-saving fan. Background Art

[0002] The impeller refers to the wheel disc equipped with moving blades, and is the general term for the wheel disc and the rotating blades installed on it. Impellers can be classified according to their shape and opening and closing conditions. As a key component of the fan, the rationality of the impeller's structural setting directly affects the overall performance of the fan. During operation, the impeller rotates, driving the gas flow, thereby realizing the discharge of the gas.

[0003] The shortcomings of the existing technology: When welding the shaft sleeve and blades in the impeller, the initial splicing of the blades usually relies on manual fixation for spot welding positioning, and lacks the function of blade splicing positioning. Manual welding can easily lead to deviations in the blade angle and position, thereby affecting the subsequent welding quality of the impeller. For this reason, we propose an impeller welding device for environmentally friendly and energy-saving fans. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an impeller welding device for an environmentally friendly and energy-saving fan to solve the problems existing in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: an impeller welding device for an environmentally friendly and energy-saving fan, comprising a workbench, a positioning seat being installed at the upper end of the workbench, a shaft sleeve being stored in the positioning seat, a positioning assembly being installed at the upper end of the workbench, the positioning assembly comprising a guide frame, a slide, a tilting frame, a support rod, a telescopic cylinder and a positioning rod, a plurality of the guide frames being equidistantly installed at the upper end of the workbench, a plurality of the slides being slidably connected to the circumferential surface of the guide frames, the tilting frames being installed at the upper end of the slide, the support rod being installed on the surface of the tilting frame, the telescopic cylinder being installed at both ends of the tilting frame, the positioning rod being slidably connected in the telescopic cylinder, a spring being installed between the positioning rod and the telescopic cylinder, and a blade being clamped between the positioning rod and the support rod; Preferably, a pair of support seats are installed on the surface of the tilting frame, the blade is located between the support seats, and the support seats are used to support and limit the upper and lower ends of the blade.

[0006] Preferably, a plurality of slide grooves are provided on the upper end surface of the workbench, push rods are slidably connected in the slide grooves, a rotating shaft is rotatably connected in the push rods, a rotating block is installed on the circumferential surface of the rotating shaft, a spring is connected between the rotating shaft and the push rods, and the rotating block is used to push the blades to fit with the sleeves.

[0007] Preferably, the lower end of the workbench is rotatably connected to a rotating disk, a plurality of inclined grooves are provided on the circumferential surface of the rotating disk, and a connecting shaft is installed at the lower end of each push rod, and the connecting shaft is located in the inclined groove and is slidably connected to the inclined groove.

[0008] Preferably, a driving motor is installed at the lower end of the workbench, a driving shaft is installed at the output end of the driving motor, and the circumferential surface of the driving shaft is fixedly connected to the rotating disk.

[0009] Preferably, a pull rod is installed on the surface of the push rod, a sliding sleeve is installed on the circumferential surface of the sliding seat, the pull rod and the sliding sleeve are slidably connected, and a plurality of limit blocks are installed on the circumferential surface of the pull rod.

[0010] Preferably, a connecting rod is installed on the surface of the positioning rod, and the connecting rod is slidably connected to the telescopic cylinder. A connecting frame is installed on the end of the connecting rod away from the positioning rod, and a mounting frame is installed on the upper end of the workbench. A driving block is installed on the surface of the mounting frame, and the driving block is slidably connected to the connecting frame.

[0011] Preferably, a plurality of mounting grooves are provided on the upper end surface of the positioning seat, and suction cups are installed in each of the mounting grooves.

[0012] The technical effects and advantages of the present invention are as follows: The present invention places the blades in the tilting frame, and at this time limits the upper and lower positions of the blades through the action of the support seat. The support rod in the tilting frame supports one side of the blade, and the positioning rod squeezes the other side of the blade through the action of the spring, so that the position of the blade can be fixed and the position of the blade can be corrected at the same time. Then, the slide can be controlled to move inward through the action of the guide frame, thereby driving the blade to fit with the shaft sleeve. Then, the connection between the blade and the shaft sleeve can be welded by external welding equipment, thereby achieving the effect of blade welding. Not only can multiple blades be positioned and spliced ​​at the same time, but the blade splicing angle position can be made more accurate through the action of the positioning component, thereby improving the efficiency and quality of impeller welding.

[0013] The present invention controls the rotation of the rotating disk, which drives the connecting shaft to move its position through the inclined groove, and the connecting shaft drives the push rod to slide in the slide groove. When the push rod moves inward, the push rod will drive the pull rod to move inward, thereby achieving the effect of driving the tilting frame and the blade to move inward synchronously. When the push rod moves outward, the push rod simultaneously drives the pull rod to move outward, and the pull rod can pull the sliding sleeve to move outward through the limit block installed on the circumferential surface, and the sliding sleeve drives the sliding seat to move outward, and the sliding seat drives the tilting frame to move outward, so that the blade is separated from the tilting frame. Since the blade is welded to the shaft sleeve through external welding equipment at this time, the tilting frame is separated from the blade. After the blade is separated from the limit of the tilting frame, the shaft sleeve can be directly taken out from the positioning seat. After the flip welding is completed, the welded blade can be directly taken out and cut. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The impeller welding device for an environmentally friendly and energy-saving fan involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] like Figure 1-7As shown, in one embodiment, an impeller welding device for an environmentally friendly and energy-saving fan is proposed, including a workbench 1, a positioning seat 101 is installed on the upper end of the workbench 1, a shaft sleeve 102 is stored in the positioning seat 101, a positioning assembly 2 is installed on the upper end of the workbench 1, the positioning assembly 2 includes a guide frame 201, a slide 202, a tilting frame 203, a support 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 slides 202 are all slidably connected to the circumferential surface of the guide frame 201, the tilting frames 203 are all installed on the upper end of the slide 202, the support rod 204 is installed on the surface of the tilting frame 203, the telescopic cylinder 205 is installed at both ends of the tilting frame 203, the positioning rod 206 is slidably connected in the telescopic cylinder 205, a spring 207 is installed between the positioning rod 206 and the telescopic cylinder 205, and a blade 208 is clamped between the positioning rod 206 and the support rod 204.

[0018] When the embodiment of the present invention is actually used, the blades 208 that need to be welded on the sleeve 102 are placed in the tilting frame 203, and the support rod 204 in the tilting frame 203 supports one side of the blade 208. The positioning rod 206 squeezes the other side of the blade 208 through the action of the spring 207, and cooperates with the support rod 204 to fix the position of the blade 208 and correct the position of the blade 208 at the same time. Then, the slide 202 can be controlled to move inward through the action of the guide frame 201, thereby driving the blade 208 to fit with the sleeve 102. Then, the connection between the blade 208 and the sleeve 102 can be welded by external welding equipment, and at the same time, the connection between the blade 208 and the sleeve 102 can be corrected. After one side is welded, the control slide 202 slides and resets on the guide frame 201, so that the blade 208 is separated from the tilting frame 203. At this time, the blade 208 and the shaft sleeve 102 are already in a connected state, and the shaft sleeve 102 can be taken out from the positioning seat 101. Then the shaft sleeve 102 and the blade 208 can be turned over, and the other side of the shaft sleeve 102 can be placed into the positioning seat 101, so that the external welding equipment can weld the other side connection of the blade 208 and the shaft sleeve 102, thereby achieving the effect of welding the blade 208. Not only can multiple blades 208 be positioned and spliced ​​at the same time, but the splicing angle position of the blade 208 is more accurate through the action of the positioning component 2, thereby improving the efficiency and quality of impeller welding.

[0019] like Figure 6 and 7 As shown, in one embodiment, a pair of support seats 209 are installed on the surface of the tilt frame 203, and the blade 208 is located between the support seats 209. The support seats 209 are used to support and limit the upper and lower ends of the blade 208.

[0020] In actual application of the embodiment of the present invention, when the blade 208 is placed in the tilting frame 203, the upper and lower positions of the blade 208 are limited by the support seat 209, and then the spring 207 pushes the positioning rod 206, and the positioning rod 206 pushes one side of the blade 208, so that the blade 208 fits with 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 blade 208. When the blade 208 fits with the shaft sleeve 102, the blade 208 can be spliced ​​with the shaft sleeve 102, and subsequently multiple blades 208 can be welded together with the shaft sleeve 102 in sequence, thereby improving the efficiency and quality of the blade 208 welding.

[0021] like Figure 4 and 5 As shown, in one embodiment, a plurality of slide grooves 3 are provided on the upper end surface of the workbench 1, and push rods 301 are slidably connected in the slide grooves 3, a rotating shaft 302 is rotatably connected in the push rod 301, a rotating block 303 is installed on the circumferential surface of the rotating shaft 302, a clockwork 304 is connected between the rotating shaft 302 and the push rod 301, and the rotating block 303 is used to push the blade 208 to fit with the sleeve 102.

[0022] When the embodiment of the present invention is actually used, when the blade 208 is placed in the tilting frame 203, the rotating block 303 will block the entrance of the tilting frame 203, and the blade 208 will push the rotating block 303 to rotate in the push rod 301. When the blade 208 is placed in the tilting frame 203, the blade 208 is out of contact with the rotating block 303, and the rotating block 303 can be driven to rotate and reset through the action of the spring 304. Since the rotating block 303 can only rotate to one side, when the push rod 301 moves inward, the rotating block 303 will fit with one side of the blade 208, pushing the blade 208 to move inward until one end of the blade 208 fits with the shaft sleeve 102, thereby achieving the effect of controlling the splicing of the blade 208 and the shaft sleeve 102.

[0023] like Figure 2 and 3 As shown, in one embodiment, the lower end of the workbench 1 is rotatably connected to a rotating disk 305, and a plurality of inclined grooves 306 are opened on the circumferential surface of the rotating disk 305. The lower end of the push rod 301 is installed with a connecting shaft 307, which is located in the inclined groove 306 and is slidably connected to the inclined groove 306.

[0024] When the embodiment of the present invention is actually used, the rotating disk 305 is controlled to rotate, and the rotating disk 305 will drive the inclined groove 306 to change its position, and the inclined groove 306 drives the connecting shaft 307 to move its position, and the connecting shaft 307 drives the push rod 301 to slide in the slide groove 3, thereby achieving the effect of pushing the blade 208 to move inward, so that the blade 208 and the shaft sleeve 102 are tightly fitted together, completing the splicing of the blade 208 and the shaft sleeve 102.

[0025] like Figure 2 As shown, in one embodiment, a driving motor 308 is installed at the lower end of the workbench 1 , a driving shaft 309 is installed at the output end of the driving motor 308 , and a circumferential surface of the driving shaft 309 is fixedly connected to the rotating disk 305 .

[0026] In actual application, the embodiment of the present invention controls the operation of the drive motor 308, the drive motor 308 drives the drive shaft 309 to rotate, and the drive shaft 309 drives the rotating disk 305 to rotate. When the drive motor 308 rotates forward, the push rod 301 can be controlled to move inward, and when the drive motor 308 rotates reversely, the push rod 301 can be controlled to move outward.

[0027] like Figure 4 As shown, in one embodiment, a pull rod 4 is installed on the surface of the push rod 301, a sliding sleeve 401 is installed on the circumferential surface of the sliding seat 202, the pull rod 4 is slidably connected to the sliding sleeve 401, and a plurality of limit blocks 402 are installed on the circumferential surface of the pull rod 4.

[0028] When the embodiment of the present invention is actually used, when the push rod 301 moves inward, the push rod 301 will drive the pull rod 4 to move inward, and the pull rod 4 can push the sliding sleeve 401 to move inward through one of the limit blocks 402 installed on the circumferential surface, and the sliding sleeve 401 will drive the slide seat 202 to move inward, thereby achieving the effect of driving the tilting frame 203 and the blade 208 to move inward synchronously. When the push rod 301 moves outward, the push rod 301 also drives the pull rod 4 to move outward, and the pull rod 4 can pass through another limit block 402 installed on the circumferential surface. Pull the sleeve 401 to move outward, the sleeve 401 drives the slide 202 to move outward, and the slide 202 drives the tilting frame 203 to move outward, so that the blade 208 is separated from the tilting frame 203. Since the blade 208 is welded to the shaft sleeve 102 by external welding equipment at this time, the tilting frame 203 is separated from the blade 208. After the blade 208 is separated from the limit of the tilting frame 203, the shaft sleeve 102 can be directly taken out from the positioning seat 101. After the flip welding is completed, the welded blade 208 can be directly taken out for cutting.

[0029] like Figure 7 and 9 As shown, in one embodiment, a connecting rod 5 is installed on the surface of the positioning rod 206, and the connecting rod 5 is slidably connected to the telescopic cylinder 205. A connecting frame 501 is installed on the end of the connecting rod 5 away from the positioning rod 206, and a mounting frame 502 is installed on the upper end of the workbench 1. A driving block 503 is installed on the surface of the mounting frame 502, and the driving block 503 is slidably connected to the connecting frame 501.

[0030] When the embodiment of the present invention is actually used, when the tilting frame 203 moves to the surroundings, the connecting frame 501 will contact the driving block 503, and then the driving block 503 will push the connecting frame 501 to move, and the connecting frame 501 drives the connecting shaft 307 to move, and the connecting rod 5 drives the positioning rod 206 to move, so that the positioning rod 206 retracts partly into the telescopic cylinder 205, increasing the distance between the positioning rod 206 and the support rod 204, which is convenient for the subsequent placement of the blade 208 into the tilting frame 203. After the blade 208 is placed in the tilting frame 203, the tilting frame 203 and the blade 208 are controlled to move inward. At this time, the connecting frame 501 will gradually disengage from the driving block 503, releasing the supporting effect on the connecting frame 501, and then through the action of the spring 207, the positioning rod 206 can be driven to reset, and the support rod 204 cooperates to squeeze the blade 208, thereby completing the effect of correcting the position of the blade 208.

[0031] like Figure 8 and 10 As shown, in one embodiment, a plurality of mounting grooves 6 are formed on the upper end surface of the positioning seat 101 , and suction cups 601 are installed in each of the mounting grooves 6 .

[0032] In actual application of the embodiment of the present invention, after the welding of one side of the sleeve 102 and the blade 208 is completed, as the tilting frame 203 moves to the four sides and resets, the sleeve 102 can be taken out of the positioning seat 101, flipped over, and put back into the positioning seat 101, and then the suction cup 601 is controlled to operate, and the suction cup 601 adsorbs the surface of the sleeve 102 to fix the sleeve 102 in the positioning seat 101, so as to prevent the position of the sleeve 102 from moving and affecting the subsequent welding of the other side of the connection between the sleeve 102 and the blade 208.
