Description

Technical Field

[0001] The present invention belongs to the technical field of impeller processing, and particularly relates to a blade positioning mechanism and an impeller processing device having the blade positioning mechanism. Background Art

[0002] The impeller is a key component in many mechanical devices and is widely used in fields such as fans, pumps, and compressors. In the manufacturing process of the impeller, welding the blades to the bottom plate is an important step. Traditional impeller welding processing technologies usually adopt manual or semi-automatic methods, which specifically include steps such as the handling of the bottom plate, the conveying, positioning, and welding of the blades. The following are the disadvantages:

[0003] 1. The current impeller welding processing still highly relies on manual operations. Specifically, the bottom plate needs to be manually carried, the blades need to be manually conveyed one by one, the welding position depends on manual positioning, and the operator needs to be involved throughout the welding process. This traditional operation mode has multiple drawbacks: on the one hand, heavy object handling and repetitive labor are likely to cause physical fatigue of the operator and significantly increase the risk of work-related accidents; on the other hand, the inefficiency of manual operations leads to a slow production rhythm and it is difficult to meet the requirements of modern industry for production efficiency.

[0004] 2. The blades need to be individually carried to the bottom plate for positioning and welding. During the sub-assembly process, displacement errors are likely to occur. Such positioning defects directly result in unstable welding quality. In severe cases, it may even cause imbalance of the blade dynamic balance, greatly affecting the aerodynamic performance and service life of the impeller. Summary of the Invention

[0010] Further, both the first clamping member and the second clamping member include clamping blocks. At the top of the clamping blocks, there are magnetic attraction blocks, and symmetrically arranged inflatable clamping fingers are provided inside the clamping blocks.

[0011] Further, a limiting block is provided on the back of the clamping block, elastic members are provided on both sides of the limiting block, and a rotating groove for accommodating the limiting block and the elastic members is provided in the first clamping seat or the second clamping seat.

[0012] An impeller processing device includes a base, on which a handling mechanism, a processing table for installing a bottom plate and blades, and a feeding mechanism for conveying the blades are assembled. The above-mentioned blade positioning mechanism is installed on the handling mechanism; the handling mechanism includes a conveying frame, on which a first cross beam is assembled through a transverse movement module, on the first cross beam, a mounting plate is assembled through a lifting module, and a rotating component is assembled on the mounting plate, and the mounting bracket is connected to the rotating component.

[0013] Further, a second cross beam is assembled on the conveying frame through a transverse movement module, and a handling seat is assembled on the second cross beam through a lifting module.

The plurality of limiting plates cooperate with the bearing plate to form a feeding cavity for stacking the bottom plates; through holes are provided at the bottom of the bearing plate, and a jacking device is assembled on the base corresponding to the through holes.

[0015] Compared with the prior art, the present application has the following beneficial technical effects:

[0019] 4. The impeller processing device provided by the present application can form an automated processing through the cooperation between the blade positioning mechanism, the handling mechanism, the feeding mechanism and the loading rack, solving the problem of low efficiency of traditional manual processing.

[0038] Reference Figures 1 to 3 , an impeller processing device, including a base 100, on which a handling mechanism 200, a welding mechanism (not shown in the drawings), a processing table 110 for installing the bottom plate and the blades, a feeding mechanism 120 for conveying the blades, and a loading rack 400 for stacking the bottom plates are assembled. The handling mechanism 200 includes a conveying frame 210, on which a first cross beam 240 and a second cross beam 250 are respectively assembled through a transverse movement module 220. On the first cross beam 240, a mounting plate 241 is assembled through a lifting module 230, and a rotating assembly 242 is assembled on the mounting plate 241. The rotating assembly 242 is connected to a blade positioning mechanism 300. On the second cross beam 250, a handling seat 251 is assembled through a lifting module 230, and a plurality of suction heads 252 for adsorbing the bottom plate are assembled at the bottom of the handling seat 251.

[0039] The working principle of the impeller processing device is as follows: First, the handling seat 251 transports the bottom plate from the loading rack 400 to the processing table 110. Then, after the blade positioning mechanism 300 clamps the blade from the feeding belt and adjusts the blade to the required angle, it is placed on the bottom plate located on the processing table 110. The welding mechanism welds the blade and the bottom plate to form an impeller. Through the cooperation among the blade positioning mechanism 300, the handling mechanism 200, the feeding mechanism 120, and the loading rack 400, the impeller processing device can realize the full-process automation of material handling, positioning, and welding.

[0040] Among them, the loading rack 400 includes a bearing plate 410, and a plurality of limiting plates 420 are connected to the side of the bearing plate 410. The plurality of limiting plates 420 cooperate with the bearing plate 410 to form a feeding cavity for stacking the bottom plates. The design of the limiting plates 420 enables the bottom plates to be neatly stacked. Through holes are provided at the bottom of the bearing plate 410, and a jack 430 is assembled on the base 100 corresponding to the through holes. The jack 430 can jack up the bottom plate, facilitating subsequent handling and processing, and can increase the loading capacity of the loading rack 400 without increasing the length of the first lifting module 230.

[0042] As an embodiment of the present application, with reference to Figures 4 to 10 , the blade positioning mechanism 300 includes a mounting frame 310, a first housing 320, and a plurality of sets of clamping modules. The mounting frame 310 and the first housing 320 are coaxially assembled, and the mounting frame 310 and the first housing 320 are assembled and connected through a first bearing 321. The plurality of sets of clamping modules are annularly distributed along the center of the mounting frame 310. A first driving cylinder 322 is assembled on the mounting frame 310, and the first housing 320 is driven by the first driving cylinder 322 to rotate relative to the mounting frame 310. Each set of clamping modules includes an inner clamping component 340 and an outer clamping component 350. The inner clamping component 340 is assembled and connected to the mounting frame 310, and the outer clamping component 350 is assembled and connected to the first housing 320. The blade positioning mechanism 300 drives the first housing 320 to rotate relative to the mounting frame 310 through the first driving cylinder 322, so that the blade clamped by the clamping component rotates with the inner clamping component 340 fixed to the mounting frame 310 as the rotation center, realizing the rapid adjustment of the angles of all blades, avoiding the inefficient operation of adjusting one by one, and significantly improving the multi-blade synchronous positioning efficiency.

[0043] Example 2

[0044] As an embodiment of the present application, on the basis of Embodiment 1, the blade positioning mechanism 300 further includes a second housing 330 coaxially assembled with the first housing 320. The first housing 320 and the second housing 330 are assembled and connected through a second bearing 331. A second driving cylinder 332 is assembled on the mounting frame 310. The second housing 330 is driven by the second driving cylinder 332 to rotate relative to the first housing 320. The inner clamping assembly 340 includes a first clamping seat 341. The top of the first clamping seat 341 is provided with a first hinge 342, the back is provided with a second hinge 343, and the front is provided with a first clamping member 344 for clamping the blade; a rotating ring seat 311 is assembled on the mounting frame 310. The first hinge 342 is connected to the mounting frame 310, and the second hinge 343 is connected to the rotating ring seat 311. The outer clamping assembly 350 includes a second clamping seat 351. The top of the second clamping seat 351 is provided with a third hinge 352, the back is provided with a fourth hinge 353, and the front is provided with a second clamping member 354 for clamping the blade; the third hinge 352 is connected to the first housing 320, and the fourth hinge 353 is assembled and connected to the second housing 330. The impeller positioning mechanism drives the second housing 330 to rotate relative to the first housing 320 through the second driving cylinder 332, so that the blade is inclined relative to the bottom plate, realizing the rapid adjustment of the inclination angle between the blade and the bottom plate, avoiding the inefficient operation of adjusting one by one, and significantly improving the multi-blade synchronous positioning efficiency. In addition, in this embodiment, the angle adjustment of the blade rotating around the inner clamping assembly 340 as the rotation center can also be performed as in Embodiment 1, by simultaneously rotating the first housing 320 and the second housing 330 by the same angle.

[0045] Further, to cooperate with the blade adjustment, a sliding rod 355 is provided on the third hinge 352. The first housing 320 has a first sliding groove 323 designed in a radial straight line shape, and the mounting frame 310 has an arc-shaped second sliding groove 312. The sliding rod 355 passes through the first sliding groove 323 and the second sliding groove 312. The fourth hinge 353 is connected with a linear actuator 356, and the linear actuator 356 is assembled on the second housing 330. When the blade is adjusted at an angle with the inner clamping assembly 340 as the rotation center, the first housing 320 rotates, driving the sliding rod 355 to slide along the second sliding groove 312. At the same time, the sliding rod 355 slides along the first sliding groove 323, so that the upper part of the outer clamping assembly 350 moves towards the axis direction of the mounting frame 310. At the same time, the linear actuator 356 drives the lower part of the outer clamping assembly 350 to move towards the axis direction of the mounting frame 310 to ensure that the whole outer clamping assembly 350 approaches the axis direction of the mounting frame 310 in a vertical posture.

[0046] To cooperate with the blade adjustment, the inner clamping assembly 340 is also designed as follows: a guide rod 345 is provided on the second hinge member 343, a guide sleeve 313 for cooperating with the guide rod 345 and a reset member 314 for assisting the reset of the guide rod 345 are provided on the rotating ring base 311. When adjusting the inclination angle between the blade and the bottom plate, the second housing 330 rotates, the outer clamping assembly 350 drives the lower part of the blade to incline, during which the linear actuator 356 performs corresponding extending and retracting actions, and the blade drives the guide rod 345 of the second hinge member 343 to perform corresponding extending and retracting.

[0047] In addition, to ensure the smooth movement of the outer clamping assembly 350 and the inner clamping assembly 340, the hinge structures including the first to fourth hinge members 353 are all designed with ball head hinges.

The elastic limiting structure formed by the limiting block 363 and the elastic members 364 can increase the friction force between the blade and the inflatable fingers 362 through the torque provided by the elastic members 364 during the blade adjustment process, further improving the clamping stability.
