Description

Technical Field

[0001] This utility model relates to the field of impeller processing technology, specifically a fixing device for processing three-dimensional flow impellers. Background Technology

[0002] An impeller refers to both the wheel disk with moving blades, which is a component of the rotor of an impulse steam turbine, and the general term for the wheel disk and the rotating blades mounted on it. Three-dimensional flow design technology divides the three-dimensional space inside the impeller infinitely according to the "three-dimensional flow theory". By analyzing each working point in the impeller flow channel, a complete and realistic mathematical model of the fluid flow inside the impeller is established, and mesh generation and flow field calculation are performed. During the machining of three-dimensional flow impellers, the impeller needs to be fixed to ensure machining accuracy.

[0003] Most current fixing devices for three-dimensional flow impeller machining can only directly fix the impeller, making it inconvenient to adjust the fixing height or the fixing angle of the impeller, thus reducing the efficiency of impeller machining. Therefore, we propose a fixing device for three-dimensional flow impeller machining to solve the above problems. Utility Model Content

[0019] 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.

[0020] Example: Figures 1-5 As shown, this utility model provides a technical solution for a fixing device for machining a three-dimensional impeller, including a base plate 1. A forward and reverse motor 3 is fixedly connected to the upper surface of the base plate 1. A threaded rod 4 is fixedly connected to the output end of the forward and reverse motor 3. A fixing frame 5 is provided on the outer surface of the threaded rod 4. A threaded hole 6 is opened on the upper surface of the fixing frame 5. The inner wall of the threaded hole 6 is threadedly connected to the outer surface of the threaded rod 4. A fixing mechanism 2 is provided on the front side of the fixing frame 5. The fixing mechanism 2 includes two hydraulic rods 201 installed on the front side of the fixing frame 5. A coupling 202 is installed on the output end of each of the two hydraulic rods 201. Each of the two devices 202 has a fixed base 203 fixedly connected to one end of each device that is close to the other. Each of the two fixed bases 203 has a geared motor 204 fixedly connected to one side of each device that is close to the other. Each of the two geared motors 204 has a positioning frame 205 installed at its output end. Through the cooperation of the forward and reverse motors 3, the threaded rod 4 and the threaded hole 6, the fixed frame 5 can be moved up and down to facilitate the adjustment of the height of the impeller. The impeller can be clamped and fixed by the cooperation of the hydraulic rod 201 and the positioning frame 205. The geared motor 204 can drive the positioning frame 205 to rotate to facilitate the adjustment of the angle of the impeller.

[0021] The fixed frame 5 moves up and down through the cooperation of the forward and reverse motor 3, the threaded rod 4, and the threaded hole 6. The impeller height can be quickly adjusted according to the processing equipment or process requirements to adapt to the processing requirements of impellers of different specifications, thus improving the versatility of the device. The hydraulic rod 201 and the positioning frame 205 provide a stable and controllable clamping force to ensure that the impeller does not shift during processing. At the same time, the geared motor 204 drives the positioning frame 205 to rotate, which can adjust the impeller angle without reclamping. This meets the multi-directional processing requirements of the complex curved surface of the three-dimensional flow impeller, reduces the number of clamping operations, reduces positioning errors, and improves processing efficiency and quality.

[0022] A symmetrical fixing plate 9 is fixedly connected to the upper surface of the base plate 1. A sliding groove 10 is provided on the front of each of the two fixing plates 9. A slider 11 is slidably connected inside each of the two sliding grooves 10. The front of each slider 11 is fixedly connected to the back of the fixing frame 5. A controller 7 is installed on the back of the base plate 1. A display screen 8 is provided on the back of the controller 7. The controller 7 and the display screen 8 work together to facilitate the operation of the device. The sliding grooves 10 and the sliders 11 work together to make the movement of the fixing frame 5 more stable.

[0023] With the cooperation of the slide groove 10 and the slider 11, when the fixed frame 5 moves up and down with the threaded rod 4, the slider 11 slides along the slide groove 10, forming a guiding constraint to prevent the fixed frame 5 from shifting laterally or shaking, ensuring the movement trajectory of the positioning frame 205, improving the stability of the device operation, and the sliding cooperation between the slider and the slide groove can reduce frictional resistance, making the lifting process of the fixed frame 5 smoother, while reducing mechanical wear and extending the service life of the equipment. With the cooperation of the controller 7 and the display screen 8, the operator can intuitively set parameters such as the speed of the forward and reverse motors 3, the extension and retraction of the hydraulic rod 201, and the rotation angle of the reduction motor 204 on the display screen 8, and monitor the operating status of the device in real time, realizing precise control and intelligent operation of the device, reducing the difficulty of operation and improving production efficiency.

[0024] Four support legs 12 are fixedly connected to the bottom surface of the base plate 1. Each support leg 12 is fixedly connected to an anti-slip seat 13 at its bottom end. A fixing cover 14 is fixedly connected to the bottom surface of the base plate 1. A storage battery 15 is installed inside the fixing cover 14. A collection groove 16 is opened on the upper surface of the base plate 1. The inner wall of the collection groove 16 is sprayed with a smooth coating. Through the cooperation of the support legs 12 and the anti-slip seat 13, the device can be stably placed to prevent the device from sliding. The storage battery 15 can provide power to the device. The collection groove 16 can collect the debris during impeller processing.

[0025] With the cooperation of the support legs 12 and the anti-slip seat 13, the four support legs are evenly distributed on the bottom surface of the base plate 1, increasing the contact area between the device and the ground. The anti-slip seat 13 is made of anti-slip material (such as rubber) to increase friction and effectively prevent the device from sliding due to vibration or external force during processing, ensuring the stability of the equipment during operation and providing reliable basic support for impeller processing. Using the battery 15, the device can be powered independently without an external power source, which is especially suitable for outdoor operations or scenarios where power access is inconvenient, improving the flexibility and portability of the device. At the same time, the collection tank 16, which is located on the upper surface of the base plate 1, has a smooth coating (such as Teflon coating) on ​​its inner wall, which reduces the adhesion of debris and facilitates the collection of metal debris or coolant generated during impeller processing. The smooth surface also prevents debris accumulation, avoiding affecting the operation of the device or polluting the working environment, while simplifying the later cleaning process and improving maintenance efficiency.

[0026] The working principle of this utility model is as follows:

[0027] In use, first connect the device to the corresponding power supply, then fully charge the battery 15. Then, with the cooperation of the support leg 12 and the anti-slip seat 13, place the device stably in a suitable position. Then, with the cooperation of the controller 7 and the display screen 8, the device can be easily controlled by the operator. Next, with the cooperation of the forward and reverse motor 3, the threaded rod 4 and the threaded hole 6, the fixed frame 5 can be moved up and down to adjust the height of the impeller. With the cooperation of the hydraulic rod 201 and the positioning frame 205, the impeller can be clamped and fixed. The geared motor 204 can drive the positioning frame 205 to rotate to adjust the angle of the impeller. When the controller 7 issues a clamping command, the hydraulic pump supplies oil to the hydraulic cylinder, pushing the piston to extend the output end of the hydraulic rod 201. The coupling 202 adopts a cross slider structure to avoid stress concentration caused by installation errors. When the fixed seat 203 drives the positioning frame 205 to contact the impeller, the pressure sensor installed inside the hydraulic rod 201 monitors the oil pressure in real time. When the pressure reaches the preset value, the hydraulic system automatically enters the pressure holding state. At this time, the clamping force of the positioning frame 205 on the impeller is stable. This constant force clamping method can effectively prevent the aluminum alloy impeller from undergoing plastic deformation due to excessive force, while ensuring that the steel impeller does not shift during high-speed cutting. The display screen 8 will display a low battery alarm and automatically switch to the external power supply mode. The collection tank 16 can collect metal chips, which will automatically slide to the bottom of the tank under gravity. During the processing, the mixture of coolant and chips will be discharged into the external recycling box through the guide channel on the edge of the collection tank 16. After a single processing is completed, the chip cleaning can be completed within 3 minutes by simply opening the quick-release baffle at the bottom of the collection tank 16. Compared with the traditional drawer-type collection structure, the cleaning efficiency is greatly improved.
