Description

Technical Field

[0001] The invention belongs to the technical field of impeller welding processing, and in particular relates to a processing device for impeller production. Background Art

[0002] Impellers are key components in many fluid machinery and are widely used in fans, pumps, compressors and other equipment. In the production process of impellers, welding the blades to the base plate is an important step. The traditional impeller welding method usually adopts step-by-step welding, that is, only one blade is welded at a time, and then the other blades are welded in sequence. This traditional welding method has the following disadvantages:

[0003] 1. Low production efficiency: Only one blade can be welded at a time, which requires multiple clamping and positioning. The utilization rate of the equipment is low, resulting in a long production process and low production efficiency.

[0004] 2. Poor welding accuracy: Multiple clamping and positioning can easily introduce errors, especially in the case of manual adjustment, it is difficult to ensure the precise position of each blade, thus affecting the overall quality and consistency of the impeller. Summary of the invention

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions.

[0006] A processing device for producing impellers, used for welding blades to a base plate to form an impeller, comprising an assembly seat, on which a clamping assembly for clamping blades and a welding assembly for welding the base plate and blades are mounted. The number of the clamping assemblies is equal to the number of blades on the finished impeller. The clamping assembly comprises an assembly frame connected to the assembly seat, and the bottom of the assembly frame is equipped with clamping air claws. The assembly seat is equipped with a first motor, the first motor is connected to an assembly plate, and a planetary transmission structure is mounted on the assembly plate. The planetary transmission structure comprises a second motor, a sun gear, a ring gear and a plurality of planetary gears, the sun gear is driven by the second motor, and the planetary gears are connected to the assembly frame in a one-to-one correspondence.

[0007] As an optimal technical solution for a processing device for impeller production, the welding assembly includes a slide rail that is adapted to the cross-sectional curve of the blade, the slide rail is fixed on an assembly frame, a slide seat is mounted on the slide rail, welding heads are mounted on both sides of the slide seat, and the clamping air claw is located between the two groups of welding heads.

[0008] As a preferred technical solution for a processing device for impeller production, the welding head is a laser welding head.

[0009] As an optimal technical solution for a processing device for producing impellers, a first connecting plate is provided at the bottom of the slide seat, the welding head is mounted on a second connecting plate, the first connecting plate and the second connecting plate are hinged, and a motor is mounted close to the hinge.

[0010] As a preferred technical solution for a processing device for producing impellers, the clamping claw comprises a clamping cylinder, the clamping cylinder is equipped with clamping fingers, and one side of the clamping finger used for clamping is equipped with an anti-slip gasket.

[0011] Compared with the prior art, the present application has the following beneficial effects: the processing device for impeller production can weld all blades at one time by setting multiple sets of clamping assemblies, which significantly improves production efficiency. At the same time, assembling the welding assembly and the clamping assembly on the same set of assembly frames is conducive to ensuring the accuracy during the welding process. In addition, the welding assembly rotates synchronously through the planetary transmission structure, ensuring the precise positioning of each blade during welding, further improving the overall quality and consistency of the impeller. This design not only simplifies the operation process, but also reduces the errors caused by multiple clamping, making the entire welding process more stable and reliable.

[0032] The processing device 500 of the present application has the dual functions of handling and welding. Specifically, the number of the clamping assemblies 520 is equal to the number of blades 150 on the finished impeller. The clamping assembly 520 includes an assembly frame 521 connected to the assembly seat 510, and the bottom of the assembly frame 521 is equipped with a clamping claw 600. By providing the clamping assemblies 520 equal to the number of blades 150, the impeller can weld all the blades 150 at one time, and the welding efficiency is high.

[0033] To ensure welding accuracy, the assembly seat 510 is equipped with a first motor 511, the first motor 511 is connected to an assembly plate 512, and the assembly plate 512 is equipped with a planetary transmission structure, which includes a second motor 540, a sun gear 541, a gear ring 542 and a plurality of planetary gears 543, the sun gear 541 is driven by the second motor 540, and the planetary gears 543 are connected to the assembly frame 521 in a one-to-one correspondence. This design can realize the synchronous rotation of multiple groups of assembly frames 521, ensure that all blades 150 maintain a consistent motion trajectory during the welding process, and improve the stability and consistency of welding.

[0034] The welding assembly 530 includes a slide rail 531 adapted to the cross-sectional curve of the blade 150, the slide rail 531 is fixed on the assembly frame 521, a slide seat 532 is mounted on the slide rail 531, and welding heads 533 are mounted on both sides of the slide seat 532.

Then the second motor 540 drives the planetary transmission structure so that all the blades 150 rotate to a specific processing angle. The welding assembly 530 welds the blade 150 and the base plate 140. After welding is completed, the processing device 500 transports the impeller to the blanking channel 120 to complete the blanking.
