Description

Technical Field

[0001] The utility model relates to the technical field of high-speed rotor cleaning, in particular to an automatic cleaning equipment for high-speed rotors of new energy electric drives. Background Technique

[0002] The permanent magnet synchronous motor (PMSM) has occupied a dominant position in the field of new energy vehicles with its high power density, high efficiency and excellent dynamic response performance. Its core advantage lies in that the rotor permanent magnet adopts rare earth neodymium iron boron material, which not only improves the torque output of the motor, but also reduces the energy consumption. In addition, the application of carbon fiber rotors further improves the high temperature resistance and high-speed stability of the motor, providing strong support for the performance improvement of new energy vehicles.

[0003] In the prior art, during the production process of the rotor, there will be certain losses after production and testing. At this time, certain impurities will be adsorbed on the rotor due to the magnetism of the rotor. Therefore, it is necessary to clean the rotor. Generally, during cleaning, it is mainly cleaned by air flow to remove the impurities and dust on the rotor, so as to achieve the cleaning effect. However, the high-speed rotor of the new energy electric drive generally has a certain magnetism itself. In the case of direct blowing, it is easy to cause the dust and impurities to be adsorbed on the rotor again. At the same time, the rotor needs to be flipped during blowing, which affects the cleaning efficiency of the rotor. Content of the Utility Model

[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Referring to Figures 1-3 , the automatic cleaning equipment for the high-speed rotor of the new energy electric drive disclosed by the present utility model includes a base frame 1 and an upper support frame 2. The upper support frame 2 is fixedly installed on the top of the base frame 1. A fixed frame 3 is fixedly installed on the top of the upper support frame 2. A cleaning chamber 4 is fixedly connected to the top of the fixed frame 3. A closing door 6 is connected to one side of the upper support frame 2 away from the cleaning chamber 4 through a moving member 5. A rotor positioning member 7 is arranged on the side of the closing door 6 close to the cleaning chamber 4. A cleaning member 8 is arranged in the cleaning chamber 4;

[0026] The cleaning member 8 includes a first hydraulic cylinder 9, a mounting frame 10, an annular air knife 11, a collection head 12, and a pipeline hole 13. The first hydraulic cylinder 9 is fixedly installed on the top side of the cleaning chamber 4. The output end of the first hydraulic cylinder 9 extends into the cleaning chamber 4. The mounting frame 10 is fixedly installed on the output end of the first hydraulic cylinder 9. The annular air knife 11 is fixedly installed on the top side of the mounting frame 10. The collection head 12 is fixedly installed on the bottom side of the mounting frame. The pipeline hole 13 is opened at the bottom of the side of the cleaning chamber 4 away from the closing door 6. Two negative pressure holes 14 are opened at the top of the side of the cleaning chamber 4 away from the closing door 6.

[0027] In this embodiment, one negative pressure pump and an air pump for driving the air knife are respectively installed in the two negative pressure holes 14 provided, which are used for extracting the air in the cleaning chamber 4 and blowing the air knife. The pipeline hole 13 is used for fixedly installing a pipeline, and the pipeline is a corrugated telescopic pipe. The two ends of the corrugated telescopic pipe are respectively connected to the pipeline hole 13 and the output end of the collection head 12, and a dust suction pump is connected at the pipeline hole 13. This is a common means in the prior art for dust suction and extracting the air in a container. When in use, the high-speed rotor is positioned at the closing door 6 through the rotor positioning member 7. Subsequently, the moving member 5 drives the closing door 6 to approach the cleaning chamber 4. Then, the closing door 6 closes and seals the cleaning chamber 4, making the closed chamber in a closed and sealed state. At the same time, the high-speed rotor also enters the cleaning chamber 4. During this period, the first hydraulic cylinder 9 drives the mounting frame 10 upward, so that the high-speed rotor is under the annular air knife 11. Then, the negative pressure pump is started to extract the air in the cleaning chamber 4. Finally, the dust suction pump and the first hydraulic cylinder 9 are started for reciprocating motion;

[0028] Therefore, during operation, the first hydraulic cylinder 9 drives the mounting frame 10 to move up and down, and at the same time drives the annular air knife 11 and the collection head 12 to move up and down, so that the high-speed rotor is located inside the annular air knife 11. The annular air knife 11 will quickly clean the high-speed rotor by means of wind force, and the provided dust suction pump will suck away the impurities and dust cleaned out, achieving the effect of cleaning the high-speed rotor. At the same time, the air direction of the air knife is downward, so that when the dust suction pump sucks air, it can suck away the dust and impurities blown away by the air knife through the pipeline and the collection head 12, avoiding the secondary adsorption of impurities and dust on the magnetic high-speed rotor and improving the cleaning effect.

[0029] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, the rotor positioning member 7 includes a support seat 15. The top side of the support seat 15 is fixedly connected with a bottom plate 16. The top end of the bottom plate 16 is fixedly connected with a hollow column 17. Symmetrically connected to the outer peripheral side top of the hollow column 17 with the axis of the hollow column 17 as a reference are positioning keys 18.

[0030] In this embodiment, the provided support seat 15 is used to install the bottom plate 16 and the hollow column 17. The hollow column 17 is for the shaft on the rotor to be inserted, and the key groove opened on the shaft of the high-speed rotor will enable the positioning keys 18 to be inserted, achieving the effect of positioning the rotor.

[0031] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, the moving member 5 includes a slide rail frame 19. The slide rail frame 19 is fixedly installed on the top side edge of the upper support frame 2. A slide frame 20 is slidably connected between the two inner side walls of the slide rail frame 19. A roller 21 is rotatably connected to the side of the slide frame 20. The outer peripheral side of the roller 21 is in contact with the top side of the slide rail frame 19. The top end of the slide frame 20 is fixedly connected with the closing door 6.

[0032] In this embodiment, the provided slide rail frame 19 is used for installing the slide frame 20, enabling the slide frame 20 to slide on the slide rail frame 19. In addition, the provided roller 21 can further provide support, facilitating the slide frame 20 to drive the closing door 6 to close the cleaning chamber 4, preventing dust from being blown out to the outside and affecting the surrounding environment.

[0033] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, the bottom side of the fixed frame 3 is fixedly connected with a second hydraulic cylinder 22. The bottom side of the closing door 6 is fixedly connected with a docking block 23. The output end of the second hydraulic cylinder 22 is fixedly connected with the docking block 23.

[0034] In this embodiment, the second hydraulic cylinder 22 is arranged to drive the docking block 23 to move towards the cleaning bin 4, and the docking block 23 is fixedly connected to the arranged closing door 6. Therefore, the second hydraulic cylinder 22 will drive the hydraulic door to move towards the cleaning bin 4, so that the closing door 6 can move stably to close the cleaning bin 4.

[0035] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, a guide plate 24 is fixedly connected to the inner side wall of the cleaning bin 4. A guide rail 25 is fixedly connected to the side of the guide plate 24 close to the installation frame 10, and the installation frame 10 is slidably connected to the guide rail 25.

[0036] In this embodiment, the arranged guide plate 24 is used to install the corresponding guide rail 25. The guide rail 25 is slidably connected to the arranged installation frame 10, so that when the first hydraulic cylinder 9 drives the installation frame 10 and the annular air knife 11 to move, the stability of the installation frame 10 and the annular air knife 11 is improved, thereby avoiding the shaking of the annular air knife 11 when moving up and down, resulting in unstable air flow due to the shaking, and further affecting the cleaning of the high-speed rotor.

[0037] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, the number of the rollers 21 is four, and there is a gap between two adjacent rollers 21.

[0038] In this embodiment, the number of the arranged rollers 21 is four, and there is a gap between two adjacent rollers 21. The four rollers 21 cooperate with the sliding frame 20 to support the closing door 6, so that the closing door 6 is prevented from tilting or shaking when moving, thereby improving the stability of the closing door 6 when moving.

[0039] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
