[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.
[0025] Example 1: This example provides a splicing fixture for centrifugal fan impeller blades, such as... Figure 1 As shown, this invention solves the problem of debris easily generated during impeller assembly, which tends to fall onto the worktable. As the operator continues to assemble the blades, the debris accumulates, potentially affecting the operator's normal work. The invention includes a worktable 1 with a clamping mechanism 2 on its top surface and a movable groove 3 on its top surface. A negative pressure adsorption mechanism 4 is rotatably mounted within the movable groove 3 to adsorb and fix the impeller. A one-way adjustment mechanism 5 is located at the bottom of the negative pressure adsorption mechanism 4 to control the impeller's rotation. A first purging mechanism 6 and a second purging mechanism 7 are also located on the top surface of the worktable 1. The air inlets of both the first purging mechanism 6 and the second purging mechanism 7 are connected to the inner wall of the movable groove 3. When the one-way adjustment mechanism 5 operates, it pushes the airflow in the movable groove 3 into the first purging mechanism 6 or the second purging mechanism 7.
[0026] First, the impeller body is placed on the operating table 1. Then, the impeller is clamped and fixed by the clamping mechanism 2, and simultaneously fixed by the negative pressure adsorption mechanism 4 to reduce the possibility of impeller rotation during blade splicing. After one blade is spliced, the impeller is controlled to rotate in one direction by the unidirectional adjustment mechanism 5, and the angle of impeller rotation is kept consistent each time, so as to rotate the impeller to the next splicing position. Then, the blade is spliced. This process is repeated to assemble the impeller blades.
[0027] When the one-way adjustment mechanism 5 operates, it alternately pushes the airflow in the movable slot 3 into the first blowing mechanism 6 or the second blowing mechanism 7, thereby causing the first blowing mechanism 6 or the second blowing mechanism 7 to alternately spray airflow to clean the debris remaining on the surface of the operating table 1, so as to reduce the possibility of debris affecting the operator's work, and at the same time reduce the amount of work required for the operator to clean the operating table 1.
[0028] Combination Figure 1 , Figure 2In this embodiment of the utility model, the clamping mechanism 2 includes two brackets 21, a double-threaded rod 22, and a motor 23. The two brackets 21 are fixedly mounted on the top surface of the operating table 1. The two ends of the double-threaded rod 22 are rotatably inserted into the two brackets 21. The motor 23 is fixedly mounted on the side wall of the bracket 21. The rotating shaft of the motor 23 is inserted into the bracket 21 and fixedly connected to one end of the double-threaded rod 22. Two connecting plates 24 are symmetrically threaded on the double-threaded rod 22. An arc-shaped clamping plate 25 is fixedly mounted on the end of the connecting plate 24 away from the double-threaded rod 22. The two brackets 21 facilitate the installation of the double-threaded rod 22. The motor 23 facilitates the rotation of the double-threaded rod 22. The two external threads with opposite directions on the double-threaded rod 22 cause the two connecting plates 24 to move in opposite directions. Then, the connecting plates 24 drive the arc-shaped clamping plate 25 to move, thereby realizing the clamping and release of the impeller.
[0029] Combination Figure 3 In an embodiment of this utility model, the one-way adjustment mechanism 5 includes a one-way bearing 51, a guide cylinder 52, an electric push rod 53, and a guide rod 54. The one-way bearing 51 is fixedly installed at the bottom of the negative pressure adsorption mechanism 4. The guide cylinder 52 is fixedly inserted into the one-way bearing 51. The electric push rod 53 is fixedly installed on the inner bottom wall of the movable groove 3. The guide rod 54 is fixedly installed at the extended end of the electric push rod 53. The upper end of the guide rod 54 is movably inserted into the guide cylinder 52 and slides in cooperation with the inner wall of the guide cylinder 52.
[0030] When the electric push rod 53 pulls the guide rod 54 down, the guide rod 54 slides along the inner wall of the guide cylinder 52, thereby causing the guide cylinder 52 to drive the one-way bearing 51 to rotate. At this time, the one-way bearing 51 is in a locked state, thereby driving the negative pressure adsorption mechanism 4 and the impeller to rotate through the one-way bearing 51, so as to move the unspliced part of the impeller to the splicing position for splicing.
[0031] When the electric push rod 53 pushes the guide rod 54 upward, it is inserted into the guide cylinder 52, thereby causing the guide cylinder 52 to drive the one-way bearing 51 to rotate in the opposite direction. At this time, the one-way bearing 51 is in the unlocked state, thereby causing the inner ring of the one-way bearing 51 to rotate, while its outer ring, negative pressure adsorption mechanism 4 and impeller remain stationary.
[0032] Combination Figure 3 In an embodiment of this utility model, a spiral groove 55 is provided on the inner wall of the guide cylinder 52, and a semi-circular block 56 is fixedly provided on the outer wall of one end of the guide rod 54 inserted into the guide cylinder 52. The semi-circular block 56 slides in cooperation with the inner wall of the spiral groove 55. When the guide rod 54 moves, the semi-circular block 56 slides along the inner wall of the spiral groove 55, thereby controlling the rotation of the guide cylinder 52 and driving the one-way bearing 51 to rotate.
[0033] Example 2: Reference Figure 2The inner side of the arc-shaped clamp 25 is provided with several ball bearings 26. The bottom surface of the arc-shaped clamp 25 slides in cooperation with the top surface of the operating table 1. By providing ball bearings 26 on the inner side of the arc-shaped clamp 25, the impeller can still rotate when it is clamped, which makes it easier for the operator to rotate the impeller and to assemble the blades from all directions.
[0034] The connecting plate 24 is L-shaped, and a limiting block 27 is fixedly installed on the bottom surface of the connecting plate 24. A limiting groove 11 corresponding to the limiting block 27 is opened on the top surface of the operating table 1. The limiting block 27 is located in the limiting groove 11 and slides in cooperation with the inner wall of the limiting groove 11. A material discharge chute 12 is opened on the rear side of the operating table 1. The limiting block 27 cooperates with the limiting groove 11 to facilitate the limiting of the connecting plate 24, so that when the double threaded rod 22 rotates, the connecting plate 24 can drive the arc-shaped clamping plate 25 to move, and at the same time increase the stability of the connecting plate 24 and the arc-shaped clamping plate 25 when they move. The material discharge chute 12 facilitates the discharge of debris on the operating table 1.
[0035] Example 3: Reference Figure 4 A piston disc 57 is fixedly installed on the outer wall of the guide rod 54. The piston disc 57 is movably installed in the movable groove 3. The movable groove 3 is divided into an upper chamber 31 and a lower chamber 32 by the piston disc 57. When the guide rod 54 moves, it drives the piston disc 57 to move synchronously. When the guide rod 54 drives the piston disc 57 to move downward, it pushes the airflow in the lower chamber 32 into the first purging mechanism 6. When the guide rod 54 drives the piston disc 57 to move upward, it pushes the airflow in the upper chamber 31 into the second purging mechanism 7.
[0036] Both the first purging mechanism 6 and the second purging mechanism 7 include a jet nozzle 71 and an air guide pipe 72. The jet nozzle 71 is bent towards the center of the operating table 1. One end of the air guide pipe 72 of the first purging mechanism 6 is fixedly connected to the jet nozzle 71, and the other end is connected to the lower chamber 32. One end of the air guide pipe 72 of the second purging mechanism 7 is fixedly connected to the jet nozzle 71, and the other end is connected to the upper chamber 31. The first purging mechanism 6 delivers the airflow in the lower chamber 32 to the jet nozzle 71 through the air guide pipe 72, and then sprays airflow through the jet nozzle 71 to clean the surface of the operating table 1. The second purging mechanism 7 delivers the airflow in the upper chamber 31 to the jet nozzle 71 through the air guide pipe 72, and then sprays airflow through the jet nozzle 71 to clean the surface of the operating table 1. The first purging mechanism 6 and the second purging mechanism 7 operate alternately.
[0037] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
