[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3 , an integrated fixture for machining impeller parts, comprising:

[0021] A fixed platform 1, the top of which is rotatably connected to a support rod 2, the top of which is fixedly connected to a mounting plate 3, the top of which is fixedly connected to a plurality of fixing rods 4, the top of each fixing rod 4 being fixedly connected to a fixing suction cup 5, which is used to adsorb and clamp the impeller blades;

[0022] The separation structure includes a fixing frame 6 fixedly sleeved on the outside of each fixing rod 4, and a pulling rod 7 is installed on each fixing frame 6. The pulling rod 7 is provided with a spiral groove. The fixing frame 6 is slidably connected to the corresponding pulling rod 7 through the spiral groove. The top of each pulling rod 7 is respectively connected to the corresponding fixed suction cup 5. When the pulling rod 7 moves, the pulling rod 7 pulls one end of the fixed suction cup 5 connected thereto, thereby allowing air to enter the inner side of the fixed suction cup 5, so that the fixed suction cup 5 is separated from the impeller blades;

[0023] The top of the fixed platform 1 is fixedly connected to the motor 10, the output end of the motor 10 is fixedly connected to the rotating rod 11, the end of the rotating rod 11 away from the motor 10 is fixedly connected to the fixed gear 12, and the support rod 2 is fixedly provided with a connecting gear 13 corresponding to the fixed gear 12, and the fixed gear 12 and the connecting gear 13 are meshed. A fixed shell 14 is installed on the outside of the motor 10, and the fixed shell 14 includes the connecting gear 13, the fixed gear 12, the motor 10 and other structures on the inside. The fixed shell 14 protects the motor 10 and other structures to prevent them from being damaged, and the fixed shell 14 is penetrated by the support rod 2. After the motor 10 is started, its output end drives the rotating rod 11 to rotate, thereby moving the fixed gear 12 fixedly connected to the rotating rod 11, and rotating the connecting gear 13 engaged with the fixed gear 12, so that the support rod 2 and the mounting plate 3 and other structures rotate, and the impeller blades are adjusted to facilitate the processing; the motor 10 adopts a servo motor, and a controller corresponding to the motor 10 is provided on the fixed table 1. The controller and the motor 10 are matching existing technologies. The motor 10 can be controlled by the controller. At the same time, the motor 10 using the servo motor can run for a period of time after starting and then automatically shut down;

[0024] Each pulling rod 7 passes through the corresponding fixing frame 6 and extends to the bottom of the fixing frame 6. One end of each pulling rod 7 located below the fixing frame 6 is fixedly connected to a fixing block 8. The top of each fixing block 8 is fixedly connected to a fixing spring 9. Each fixing spring 9 is respectively sleeved on the outside of the corresponding pulling rod 7, and one end of each fixing spring 9 away from the pulling rod 7 is fixedly connected to the bottom end of the corresponding fixing frame 6. The fixing block 8 is rotated to move the pulling rod 7 and stretch the fixing spring 9. After loosening the fixing block 8, the elastic force of the fixing spring 9 causes the pulling rod 7 to return to its original position, allowing the fixed suction cup 5 to be adsorbed again; the side walls of each fixing block 8 are provided with grooves to facilitate the adjustment of the fixing block 8;

[0025] The top end of each pull rod 7 is fixedly connected to a fixed pad, and each pull rod 7 is fixedly connected to the fixed suction cup 5 through the fixed pad, so as to avoid damage to the fixed suction cup 5 when the pull rod 7 is pulled.

[0026] When the device is in use, the impeller blades are first set on the fixed suction cup 5, and the fixed suction cup 5 is used to adsorb and clamp it, and then the impeller is processed. During the processing, the motor 10 is started. After the motor 10 is started, its output end drives the rotating rod 11 to rotate, so that the fixed gear 12 fixedly connected to the rotating rod 11 moves accordingly, and the connecting gear 13 engaged with the fixed gear 12 rotates together, so that the support rod 2 and the mounting plate 3 and other structures rotate, and the impeller blades are adjusted to facilitate the processing. After the processing is completed, the fixed block 8 is rotated to move the pulling rod 7 and stretch the fixing spring 9. When the pulling rod 7 moves, it pulls one end of the fixed suction cup 5 connected to it, so that air enters the inner side of the fixed suction cup 5, so that the fixed suction cup 5 is separated from the impeller blades, so that the impeller blades can be easily removed. At the same time, after loosening the fixed block 8, the elastic force of the fixing spring 9 causes the pulling rod 7 to return to its original position, so that the fixed suction cup 5 can be adsorbed again.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
