Abstract
Description
Technical Field
[0001] This utility model relates to the field of impeller processing technology, and in particular to a fan impeller processing table with automatic blade positioning function. Background Technology
[0002] The impeller is the core component of a fan. It is usually composed of multiple blades, a disc, a hub, and some auxiliary components (such as reinforcing ribs and wear-resistant coatings). Multiple blades are installed on the hub at specific angles and spacings and connected to the disc. During operation, a power source such as a motor drives the impeller to rotate at high speed. The blades generate airflow through rotation, converting mechanical energy into the kinetic energy of the air, giving the gas velocity and pressure energy, and realizing the intake, compression, and exhaust of the gas.
[0003] A search revealed that the document with publication number "CN222702224U" states that "this utility model relates to the field of wind turbine impellers and discloses a detachable wind turbine impeller, including a disc. A connecting block connected to an external motor drive shaft is fixedly installed in the middle of one side of the disc. Blades are provided between the connecting block and the disc. A protective plate is attached to the side of the blades located in front of the connecting block in the direction of rotation." In use, this utility model attaches the protective plate to the side of the blades located in front of the connecting block in the direction of rotation, and tightens it with the first bolt in sequence to fix the protective plate to the blades. Thus, when the blades rotate, impurity particles in the gas will collide with the protective plate, preventing damage to the blades and solving the problem of short blade life in existing wind turbine impellers.
[0004] However, in the processing of wind turbine impellers, the positioning accuracy of the blades is crucial to ensuring the overall quality and performance of the impeller. In traditional impeller processing methods, the impeller disk is usually fixed by a simple mechanical slot, which can easily cause the impeller disk to rotate during processing, affecting the accuracy and efficiency of blade processing. As for the positioning of the impeller blades, workers generally need to manually adjust and position them during welding, which is cumbersome and the positioning accuracy is difficult to guarantee.
[0005] Therefore, we provide a wind turbine impeller processing table with automatic blade positioning function to solve the above problems. Utility Model Content
[0006] To overcome the above deficiencies, this utility model provides a fan impeller processing table with automatic blade positioning function.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A wind turbine impeller processing table with automatic blade positioning function includes a processing table plate. An automatic blade positioning component is installed on the upper side of the processing table plate. The automatic blade positioning component includes a limiting groove on the upper side of the processing table plate, an impeller groove in the middle of the limiting groove, a magnetic suction plate on the surface of the impeller groove, an impeller disk installed inside the impeller groove, a fixing bracket connected to the inner side of the limiting groove, a scale on the upper surface of the fixing bracket, a top plate above the fixing bracket, stepper motors installed inside the top plate, shaft clips connected to the lower side of the stepper motors, blade clamps installed inside the shaft clips, impeller blades installed inside the blade clamps, laser emitters connected to the front and rear ends of the upper side of the impeller blades, and laser angle probes on both the front and rear sides of the stepper motors.
[0009] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:
[0016] The blade clips and shaft clips are in one-to-one correspondence, and the shaft clips and blade clips are fixed together by screws.
[0017] As a further description of the above technical solution:
[0018] The impeller blades and the blade clamps are connected by a slot. The inner surface of the blade clamps is covered with a rubber sheet. The blade clamps and the impeller blades are adjusted at an angle by a stepper motor through a shaft clamp.
[0019] As a further description of the above technical solution:
[0020] The laser angle probe is electrically connected to the laser emitter, and the laser angle probe is electrically connected to the stepper motor. The laser angle probe and the stepper motor together form an automatic positioning and adjustment structure.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. This utility model uses an automatic positioning component for blade processing. When needed, the impeller disk is first embedded into the impeller groove, and the groove fits tightly to ensure that the impeller disk is stable and does not move, which further improves the accuracy and efficiency of blade processing. The magnetic suction plate will firmly attract the impeller disk inserted into the impeller groove to ensure processing accuracy and avoid rotation during processing, thereby improving the stability and accuracy of blade positioning.
[0023] 2. This utility model uses an automatic positioning component for blade processing. The operator inserts the blade clamp containing the impeller blades into the shaft clip and fixes it with a pin. This allows the operator to fix the impeller blades to the blade clamps in advance. During welding, the blade clamps are directly connected to the shaft clips, improving work efficiency. At this time, two sets of laser angle probes receive the light signals emitted by the individual laser emitters on the impeller blades, thereby achieving the function of automatically positioning the rotation angle of the impeller blades, and automatically adjusting it in conjunction with a stepper motor.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a wind turbine impeller processing table with automatic blade positioning function, including a processing table 1, an automatic blade positioning component 2 installed on the upper side of the processing table 1, the automatic blade positioning component 2 including a limiting groove 201 set on the upper side of the processing table 1, an impeller groove 202 set in the middle of the limiting groove 201, a magnetic suction plate 203 set on the surface of the impeller groove 202, an impeller disk 204 installed on the inner side of the impeller groove 202, and a fixing bracket 20 connected to the inner slot of the limiting groove 201. 5. A scale 206 is provided on the upper surface of the fixed card holder 205. A top plate 207 is provided above the fixed card holder 205. A stepper motor 208 is installed on the inner side of the top plate 207. A shaft clip 209 is connected to the lower side of the stepper motor 208. A blade clip 210 is installed on the inner side of the shaft clip 209. An impeller blade 211 is installed on the inner side of the blade clip 210. A laser emitter 212 is connected to the front and rear ends of the upper side of the impeller blade 211. A laser angle probe 213 is provided on both the front and rear sides of the stepper motor 208.
[0033] Furthermore, the magnetic suction plate 203 is bonded to the impeller groove 202, and the magnetic suction plate 203 is magnetically attracted to the impeller disk 204. When needed, the magnetic suction plate 203 will firmly attract the impeller disk 204 that is stuck in the impeller groove 202, ensuring processing accuracy and avoiding rotation during processing, thereby improving the stability and accuracy of blade positioning.
[0034] Furthermore, the impeller disk 204 and the impeller groove 202 are connected by a slot. The impeller disk 204 and the impeller groove 202 have the same diameter. When needed, the impeller disk 204 is embedded into the impeller groove 202. The slot fits tightly, ensuring that the impeller disk 204 is stable and does not move, which further improves the precision and efficiency of blade processing.
[0035] Furthermore, the scale 206 and the fixed bracket 205 are evenly distributed, and the scale 206 and the fixed bracket 205 are at the same center. When needed, the staff can observe the scale 206 to help determine the angle position of the impeller blade 211 and ensure the accuracy of the blade installation.
[0036] Furthermore, the blade clips 210 and the shaft clips 209 are in one-to-one correspondence, and the shaft clips 209 and the blade clips 210 are fixed together by screws. When needed, the operator inserts the blade clips 210 containing the impeller blades 211 into the shaft clips 209 and fixes them with pins. This allows the operator to fix the impeller blades 211 and the blade clips 210 in advance, and then directly connect the blade clips 210 and the shaft clips 209 during welding, thus improving work efficiency.
[0037] Furthermore, the impeller blade 211 and the blade clamp 210 are connected by a slot. The inner surface of the blade clamp 210 is covered with a rubber sheet. The blade clamp 210 and the impeller blade 211 are adjusted in angle by the shaft clamp 209 and the stepper motor 208. When needed, the impeller blade 211 can be fixed by the rubber sheet of the blade clamp 210 to increase friction and prevent the impeller blade 211 from falling out of the blade clamp 210. The impeller blade 211 is rotated and adjusted by the stepper motor 208 driving the shaft clamp 209, ensuring precise adjustment of the blade angle and reducing human error.
[0038] Furthermore, the laser angle probe 213 is electrically connected to the laser emitter 212, and the laser angle probe 213 is electrically connected to the stepper motor 208. The laser angle probe 213 and the stepper motor 208 together form an automatic positioning and adjustment structure. When needed, the two sets of laser angle probes 213 respectively receive the light signals emitted by the individual laser emitters 212 on the impeller blades 211, thereby achieving the function of automatically positioning the rotation angle of the impeller blades 211, and automatically adjusting in conjunction with the stepper motor 208.
[0039] Working principle: When needed, the operator places the processing table 1 in the required position, then installs the impeller blades 211 into the blade clamps 210, and aligns the blade clamps 210 with the shaft clips 209, locking them with pins. After preparation, the impeller disk 204 is placed into the impeller groove 202, and the impeller disk 204 is magnetically attracted and fixed using the magnetic suction plate 203. After preparation, the fixing bracket 205 is inserted into the limiting groove 201, at which point the top plate 207 will be in an inverted state. After preparation, the laser emitter 212 emits a light signal, and the laser angle probe 213 receives the data. According to the computer preset, it controls the stepper motor 208 to drive the impeller blades 211 to rotate and adjust through the shaft clips 209, so that each set of impeller blades 211 reaches the preset angle, ensuring processing accuracy. Finally, the operator performs single-point welding for fixation, and then disassembles and performs complete welding. This completes the use of a fan impeller processing table with automatic blade positioning function.
