Description
Technical Field
[0001] This utility model belongs to the field of fixture technology, specifically relating to a rotor core turning and lifting fixture. Background Technology
[0002] In the field of rotor core turning, with the increasing demands for product precision and quality in industrial production, traditional machining methods face many pressing problems. During rotor core turning, the intense friction between the turning tool and the rotor core generates a large amount of heat. Excessive temperature has several negative impacts on the machining process. On the one hand, it significantly shortens the service life of the turning tools, and frequent tool replacements not only increase production costs but also reduce production efficiency. On the other hand, high temperatures may cause localized thermal deformation of the rotor core, severely affecting its machining accuracy and failing to meet the production requirements of high-precision products.
[0003] Traditional cooling methods, such as coolant spraying, while effective in lowering temperatures, have significant drawbacks. The continuous use of coolant requires substantial water resources and involves a series of processes including storage, recycling, and treatment, consuming considerable external resources and increasing production costs and environmental burden. Furthermore, the spraying range and effectiveness are limited, making it difficult to comprehensively and precisely cool the machining area. In addition, impurities such as metal shavings generated during turning are a significant problem. If these impurities are not cleaned promptly, they can easily mix into the machined parts, affecting product performance and quality, and potentially leading to product failure. Traditional cleaning methods often require manual operation or additional cleaning equipment, which is not only inefficient but also fails to guarantee thorough cleaning. Utility Model Content

[0013] Compared with the prior art, this utility model provides a rotor core turning and lifting fixture, which has the following advantages:
[0014] This invention adds a novel wind-assisted device to the left side of the chuck body. After the chuck body clamps the rotor core to be machined using multiple metal jaws, it rotates at high speed to allow the turning tool to machine the rotor core. During rotation, the metal fixing ring of the wind-assisted device drives multiple rectangular fan blades fixed at equal intervals on its outer wall to rotate. When these high-speed rotating rectangular fan blades pass through a wind shroud fixed to the top of the power unit, the shroud collects the airflow generated by the rotation of the rectangular fan blades. This airflow is then collected by a collection shroud and ejected outwards through a universal joint. The universal joint, through a blower head, directs the airflow towards the machining position, achieving both cooling and cleaning. During the machining of the rotor core, the turning tool and the rotor core... Core friction generates a large amount of heat. Excessive temperature not only affects the service life of turning tools but may also adversely affect the machining accuracy of the rotor core. The airflow generated by the wind-assisted device can quickly remove heat, reduce the temperature of the machining area, extend tool life, and ensure machining accuracy. At the same time, turning processes produce impurities such as iron filings. If these impurities are not cleaned in time, they may mix into the machined parts, affecting product quality. The airflow from the wind-assisted device can effectively blow away iron filings and other impurities, keeping the machining area clean and improving product quality. Moreover, the wind-assisted device has a simple structure, using the rotation of the chuck to drive the fan blades to generate airflow. No additional power unit is required, reducing equipment costs and energy consumption, and it has good practicality and economy. Attached Figure Description

[0021] 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.
[0022] This utility model provides, for example Figure 1-5The rotor core turning and lifting fixture shown includes a power housing 2 and a lifting housing 1 connected to the bottom of the power housing 2. A chuck body 3 is provided at the center of the right end of the power housing 2. Multiple jaw adjustment slots 4 are equidistantly arranged on the outer side of the center of the right end of the chuck body 3. The multiple jaw adjustment slots 4 are all arranged with their openings facing right inside the right end of the chuck body 3. Each of the multiple jaw adjustment slots 4 is provided with a jaw movable block 5. Each of the multiple jaw movable blocks 5 is provided with a metal jaw 6 at its right end, and the multiple metal jaws 6 are all located at the right end of the chuck body 3. The front end of the chuck 3 has an adjustment hole with an adjustment bolt inside. Rotating the adjustment bolt clockwise or counterclockwise via gear transmission drives multiple jaw moving blocks 5 to move back and forth synchronously in the jaw adjustment slots 4. Before machining the rotor core, the rotor core must first be fixed to the fixture. This fixture achieves this function through the jaw structure on the chuck body 3. Multiple jaw adjustment slots 4 are equidistantly arranged on the outer side of the center of the right end of the chuck body 3. Each jaw adjustment slot 4 contains a jaw moving block 5, and the right end of the jaw moving block 5 is connected to a metal jaw 6. An adjusting bolt is installed in the adjusting hole inside the front end of the chuck body 3. When the adjusting bolt rotates clockwise or counterclockwise, it drives multiple jaw moving blocks 5 to move back and forth synchronously in the jaw adjusting groove 4 through gear transmission. In this way, the operator can flexibly adjust the position of multiple metal jaws 6 according to the size of the rotor core, so that they evenly clamp the rotor core, ensuring that the rotor core remains stable during turning and avoiding the impact on machining accuracy due to loosening. The power unit 2 has a power motor fixed inside by the frame. The motor shaft of the power motor faces to the right, and The right end of the motor shaft is fixedly connected to the chuck body 3. The power motor can drive the chuck body 3 to rotate through the motor shaft. A junction box 9 is provided on the outer wall of the right end of the power housing 2. After the power motor is connected to the power source, the motor shaft starts to rotate, which in turn drives the chuck body 3 to rotate synchronously. The rotation of the chuck body 3 provides the necessary circular motion for turning, so that the turning tool can perform cutting operations on the rotor core. The junction box 9 provided on the outer wall of the right end of the power housing 2 facilitates connection to an external power source to provide power support for the power motor and ensure the normal operation of the entire fixture system.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a lifting hydraulic cylinder 14 is vertically fixed inside the center of the lifting housing 1. A hydraulic shaft 12 is installed within the lifting hydraulic cylinder 14. A hydraulic connector 8 is installed on the outer wall of the bottom left end of the lifting housing 1, and the hydraulic connector 8 is connected to the lifting hydraulic cylinder 14. Lifting guide sleeves 11 are installed on both the front and rear sides of the lifting hydraulic cylinder 14, and the lifting guide sleeves 11 are vertically fixed inside the lifting housing 1. Lifting guide columns 13 are inserted into each of the two lifting guide sleeves 11, and the lifting guide columns 13 can move up and down inside the lifting guide sleeves 11. A fixed top plate 10 is connected to the top of the hydraulic shaft 12 and the two lifting guide columns 13. The fixed top plate 10 is fixedly connected to the bottom of the power housing 2 by multiple embedded screws. The lifting hydraulic cylinder 14 can drive the fixed top plate 10 to move up and down through the hydraulic shaft 12, and the fixed top plate 10, in turn, drives the power housing 2 to move up and down. The lifting housing 1 plays a role in adjusting the height in the entire clamping system. The lifting mechanism plays a crucial role. A lifting hydraulic cylinder 14 is vertically fixed inside the center of the lifting housing 1. A hydraulic shaft 12 is installed within the lifting hydraulic cylinder 14. A hydraulic connector 8 on the outer wall of the left bottom of the lifting housing 1 connects to an external hydraulic system. By controlling the inflow and outflow of hydraulic oil, the extension and retraction of the hydraulic shaft 12 are achieved. Lifting guide sleeves 11 are installed on both the front and rear sides of the lifting hydraulic cylinder 14. Lifting guide columns 13 are inserted into the lifting guide sleeves 11 and can move up and down inside the lifting guide sleeves 11. A fixed top plate 10 is connected to the top of the hydraulic shaft 12 and the two lifting guide columns 13. The fixed top plate 10 is fixedly connected to the bottom of the power housing 2 via embedded screws. When the hydraulic shaft 12 extends or retracts, it drives the fixed top plate 10 to move up and down, thereby achieving the up and down movement of the power housing 2. This height adjustment function allows the fixture to adapt to different turning equipment and working scenarios, improving the fixture's versatility and applicability.
[0024] like Figure 1 and Figure 5As shown, a wind-powered auxiliary device 7 is provided on the outer left side of the chuck body 3. The wind-powered auxiliary device 7 includes a rectangular fan blade 15, a fan blade fixing ring 16, a wind shroud 17, and a gas collection shroud 18. The fan blade fixing ring 16 is sleeved and fixed to the outer circular side of the left side of the chuck body 3. Multiple rectangular fan blades 15 are welded at equal intervals to the outer circular wall of the fan blade fixing ring 16. A wind shroud 17 is provided above the top of the fan blade fixing ring 16. The wind shroud 17 is fixed to the outer top of the power unit housing 2 by screws. The bottom of the wind shroud 17 is open. The opening is located directly above the top of the blade fixing ring 16. The top of the wind turbine cover 17 is connected to an air collecting hood 18, which communicates with the interior of the wind turbine cover 17. When the chuck body 3 rotates clockwise and counterclockwise, it synchronously drives the blade fixing ring 16 to rotate. When the blade fixing ring 16 drives the multiple rectangular blades 15 on the outer wall to rotate, all the rectangular blades 15 pass through the inner area at the bottom of the wind turbine cover 17. The wind turbine cover 17 has openings at both the front and rear ends at the bottom for the rectangular blades 15 to pass through. The chuck body 3, which rotates without contacting the wind turbine shroud 17, rotates at high speed during rotor core turning without contacting the wind turbine shroud 17. The fan blade fixing ring 16 is sleeved on the outer circular side of the left end of the chuck body 3. This connection method allows the fan blade fixing ring 16 to rotate synchronously when the chuck body 3 rotates clockwise and counterclockwise. Multiple rectangular fan blades 15 are welded equidistantly to the outer circular wall of the fan blade fixing ring 16. When the fan blade fixing ring 16 rotates, the multiple rectangular fan blades 15 rotate accordingly. According to the principles of fluid mechanics, the rotating rectangular fan blades 15 will push the surrounding air to flow, generating airflow. The function of the air collecting shroud 18 is to further gather the airflow collected by the wind turbine shroud 17. The cross-sectional area of the top end of the air collecting shroud 18 is smaller than that of the bottom end. This variable cross-section design utilizes the characteristics of fluid flow in a pipe. When the airflow flows from a larger cross-section to a smaller cross-section, the airflow speed increases and the pressure decreases, thereby accelerating and pressurizing the airflow, enabling the airflow to be transmitted to the required location more effectively.
[0025] like Figure 1 and Figure 5As shown, the wind-assisted device 7 also includes an air outlet 19, a universal tube 20, and a blower head 21. An air outlet 19 is located at the center of the top of the air collection hood 18. The top of the air outlet 19 is connected to the universal tube 20, and one end of the universal tube 20's air outlet is connected to the blower head 21. The cross-sectional area of the top of the air collection hood 18 is smaller than that of the bottom. When the chuck body 3 rotates, it synchronously drives the fan blade fixing ring 16 to rotate. The fan blade fixing ring 16 then drives multiple rectangular fan blades 15 on the outer wall to rotate. During rotation, the multiple rectangular fan blades 15 all pass through the inner area of the bottom of the wind hood 17. The front and rear ends of the bottom of the wind hood 17 have openings for the rectangular fan blades 15 to pass through. The rectangular fan blades 15 do not contact the wind hood 17 during rotation. The wind hood 17 is fixed to the top of the power housing 2. When the high-speed rotating rectangular fan blades 15 pass through the wind hood 17, the wind hood 17 collects... The airflow generated by the rotation of the rectangular fan blade 15 is collected by the air collection hood 18 and discharged through the air outlet 19 at the center of the top of the air collection hood 18. The top of the air outlet 19 is connected to the universal tube 20, and one end of the universal tube 20 is connected to the blower head 21. The cross-sectional area of the top of the air collection hood 18 is smaller than that of the bottom, which helps to enhance the pressure and speed of the airflow. Finally, the airflow acts on the turning position through the blower head 21, which plays a role in cooling and cleaning. During the turning process, the friction between the turning tool and the rotor core generates a lot of heat. Excessive temperature will affect the service life and machining accuracy of the turning tool. The airflow generated by the wind-assisted device 7 can quickly remove the heat and reduce the temperature of the machining area. At the same time, the iron filings and other impurities generated during the turning process will also be effectively blown away by the airflow, keeping the machining area clean and improving product quality.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
