Description

Technical Field

[0001] This utility model belongs to the field of oil-cooled motor rotor technology, specifically a cleaning device for oil-cooled motor rotors used in new energy vehicles. Background Technology

[0002] The oil-cooled motor rotor cleaning device for new energy vehicles is a specialized device designed to clean the oil-cooled motor rotor in new energy vehicles. Through specific cleaning processes and mechanisms, the device efficiently and thoroughly cleans the oil-cooled motor rotor to remove surface oil, metal shavings, dust and other impurities, ensuring that the rotor meets high cleanliness requirements before assembly.

[0003] For example, utility model publication CN219541063U discloses a motor rotor shaft cleaning device, including a housing. A turntable is rotatably connected inside the housing. Multiple arc-shaped grooves are evenly distributed on the turntable. Two limiting rollers and two driving rollers are symmetrically rotatably connected to the lower part of the housing. Each of the two driving rollers is equipped with a sprocket and connected by a chain. A cleaning cloth is installed on the two limiting rollers and the two driving rollers. The position of the rotor shaft is restricted by the turntable and the inner wall of the housing, and the rotor shaft is moved. When the rotor shaft moves to the lower part, the oil stains on the surface of the rotor shaft can be cleaned by the taut and moving cleaning cloth and the water mixed with the cleaning agent. This device only requires manual placement of the rotor shaft, eliminating the manual cleaning process, reducing labor intensity, and improving work efficiency.

[0004] Although the device eliminates the need for manual cleaning by simply placing the rotor shaft, thus reducing workload and increasing efficiency, the turntable only has an arc-shaped groove. While this design can accommodate the rotor shaft, it provides limited constraint. As the rotor shaft rotates with the turntable, especially under the influence of external forces such as the friction of the cleaning agent and cleaning cloth, the rotor shaft is prone to wobbling or axial displacement within the groove. Lacking precise clamping and positioning functions, the rotor position can easily shift during the cleaning process, thereby affecting the cleaning effect. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an oil-cooled motor rotor cleaning device for new energy vehicles, which solves the problem that the device lacks precise clamping and positioning functions, and that the rotor position is easily misaligned during the cleaning process, thus affecting the cleaning effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for an oil-cooled motor rotor of a new energy vehicle, comprising a cleaning tank, wherein an electric slide rail is provided inside the cleaning tank, a bracket is mounted on the electric slide rail via an electric slider, and a limit mechanism is provided on the top of the bracket;

[0007] The limiting mechanism includes a clamping block fixedly connected to the top surface of the bracket. Limiting blocks are symmetrically distributed on both sides of the clamping block. A first rack is fixedly connected to one end of the limiting block. The first rack is meshed with a gear. The gear is meshed with a second rack. A buffer is also provided on one side of the limiting block.

[0008] Preferably, a cleaning mechanism is provided at one end of the cleaning tank, a base is fixedly connected to the bottom surface of the cleaning tank, and the electric sliders are symmetrically distributed on both sides inside the cleaning tank.

[0009] Preferably, the cleaning mechanism includes a liquid storage tank, a connecting pipe, a fixed pipe, and a nozzle. One end of the liquid storage tank is connected to the connecting pipe via a liquid pump. One end of the connecting pipe is connected to one end of the fixed pipe. The nozzle is connected to the bottom surface of the fixed pipe.

[0010] Preferably, the liquid storage tank is fixedly connected to the surface of one end of the cleaning tank by a fixing plate, and the top surface of the cleaning tank is provided with a placement groove, which is adapted to the nozzle, and the nozzle is located inside the cleaning tank.

[0011] Preferably, the bracket includes a crossbar fixedly connected to the top surface of the electric slide rail, and inclined plates are fixedly connected to both sides of the top surface of the crossbar, with a vertical plate fixedly connected to one end of the inclined plate.

[0012] Preferably, the bottom surface of the clamping block is fixedly connected to the middle end of the top surface of the crossbar, and a telescopic spring is fixedly connected to one side of the limiting block. One end of the telescopic spring is connected to the inner wall of the clamping block. The buffer includes a telescopic rod fixedly connected to the surface of one side of the limiting block. One end of the telescopic rod is slidably connected to a sliding frame. A return spring is fixedly connected inside the sliding frame. One end of the return spring is connected to the end of the telescopic rod near the sliding frame.

[0013] Preferably, one end of the sliding frame is connected to one side of the vertical plate, and a cylinder is fixedly installed on the other side of the vertical plate, with the output end of the cylinder connected to the second rack.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes an electric slide rail and a limiting mechanism. The output end of the cylinder pushes the second rack, which meshes with a gear. As the gear rotates, the first rack, meshing with the gear, moves in the opposite direction, causing the limiting block to move towards the center of the clamping block. The telescopic spring is stretched, allowing the object to be cleaned to be placed inside the clamping block and fixed in place. The electric slider moves on the electric slide rail, moving the bracket and the object to be cleaned fixed thereon to a suitable cleaning position. The pump is then activated, drawing the cleaning fluid from the storage tank into the connecting pipe, then into the fixed pipe, and finally out of the nozzle to clean the object. The cylinder-driven limiting mechanism accurately fixes the object to be cleaned within the clamping block. This precise fixing method ensures that the object will not shift during cleaning, guaranteeing the accuracy and comprehensiveness of the cleaning. Especially for irregularly shaped objects or objects requiring high precision in cleaning position, this stable fixing prevents incomplete cleaning or damage caused by the impact of the cleaning fluid.

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a cleaning device for an oil-cooled motor rotor of a new energy vehicle, including a cleaning tank 1, an electric slide rail 2 is provided inside the cleaning tank 1, a bracket 3 is mounted on the electric slide rail 2 via an electric slider, and a limit mechanism 4 is provided on the top of the bracket 3.

[0024] The limiting mechanism 4 includes a clamping block 41 fixedly connected to the top surface of the bracket 3. Limiting blocks 42 are symmetrically distributed on both sides of the clamping block 41. A first rack 43 is fixedly connected to one end of the limiting block 42. The first rack 43 is meshed with a gear 44. The gear 44 is meshed with a second rack 45. A buffer 46 is also provided on one side of the limiting block 42.

[0025] The above solution provides a closed working space for the entire cleaning process, preventing cleaning fluid from splashing. It also houses components such as the electric slide rail 2, the support 3, and the cleaning mechanism 5. The electric slide rail 2 provides a moving track for the electric slider, which drives the support 3 and the objects on it to move within the cleaning tank 1, enabling the objects to be cleaned at different positions.

[0026] like Figures 1 to 5 As shown, a cleaning mechanism 5 is provided at one end of the cleaning tank 1. A base is fixedly connected to the bottom surface of the cleaning tank 1. Electric sliders are symmetrically distributed on both sides inside the cleaning tank 1. The cleaning mechanism 5 includes a liquid storage tank 51, a connecting pipe 52, a fixing pipe 53, and a nozzle 54. One end of the liquid storage tank 51 is connected to the connecting pipe 52 through a liquid pump. One end of the connecting pipe 52 is connected to one end of the fixing pipe 53. The nozzle 54 is connected to the bottom surface of the fixing pipe 53. The liquid storage tank 51 is fixedly connected to the surface of one end of the cleaning tank 1 through a fixing plate. A placement groove is provided on the top surface of the cleaning tank 1. The placement groove is adapted to the nozzle 54, and the nozzle 54 is located inside the cleaning tank 1.

[0027] The above scheme is adopted: the clamping block 41 is located at the top of the bracket 3 and is the basic component for placing the object to be cleaned. It works with the limiting block 42 to fix the object. Under the action of the telescopic spring 421 and the gear 44 rack mechanism, the limiting block 42 can move towards or away from the center of the clamping block 41, thereby clamping or releasing the object to be cleaned. The first rack 43, the gear 44, and the second rack 45 constitute a transmission mechanism. The second rack 45 is driven by a cylinder to realize the synchronous movement of the limiting block 42, thereby completing the clamping and releasing operation of the object. The telescopic spring 421 provides the limiting block 42 with elastic force towards the center of the clamping block 41 to assist in clamping the object and is stretched when releasing. When the limiting block 42 moves, especially during the clamping process, it plays a buffering role to prevent damage to the object or the equipment itself due to excessive impact force.

[0028] like Figures 1 to 5 As shown, the bracket 3 includes a crossbar fixedly connected to the top surface of the electric slide rail 2. Inclined plates 31 are fixedly connected to both sides of the top surface of the crossbar. A vertical plate 32 is fixedly connected to one end of the inclined plate 31. The bottom surface of the clamping block 41 is fixedly connected to the middle end of the top surface of the crossbar. A telescopic spring 421 is also fixedly connected to one side of the limiting block 42. One end of the telescopic spring 421 is connected to the inner wall of the clamping block 41. The buffer 46 includes a telescopic rod 461 fixedly connected to the surface of one side of the limiting block 42. A sliding frame 462 is slidably connected to one end of the telescopic rod 461. A return spring 463 is fixedly connected inside the sliding frame 462. One end of the return spring 463 is connected to the end of the telescopic rod 461 near the sliding frame 462. One end of the sliding frame 462 is connected to one side of the vertical plate 32. A cylinder is fixedly installed on the other side of the vertical plate 32. The output end of the cylinder is connected to the second rack 45.

[0029] The above scheme is adopted: the storage tank 51 stores the cleaning fluid and provides the source of cleaning fluid for the cleaning process. The connecting pipe 52 connects the storage tank 51 and the fixed pipe 53. Under the action of the pump, the cleaning fluid flows from the storage tank 51 into the fixed pipe 53. Finally, the cleaning fluid is evenly sprayed onto the object to be cleaned through the nozzle 54. The pump provides power for the flow of the cleaning fluid, ensuring that the cleaning fluid can smoothly reach the nozzle 54 from the storage tank 51.

[0030] The working principle and usage process of this utility model: The equipment is installed in a suitable working area. The cleaning tank 1 is kept stable by the base on the bottom surface. The liquid storage tank 51 is fixed to one end surface of the cleaning tank 1 by the fixing plate and is filled with cleaning liquid. The electric sliders are symmetrically distributed on both sides inside the cleaning tank 1. The electric slide rail 2 is in the initial state. The nozzle 54 is located in the placement slot inside the cleaning tank 1.

[0031] When the cylinder is activated, the output end of the cylinder pushes the second rack 45. Since the second rack 45 meshes with the gear 44, the gear 44 rotates, and the first rack 43 meshing with the gear 44 moves in the opposite direction, causing the limiting block 42 to move towards the center of the clamping block 41. The telescopic spring 421 is stretched. At this time, the object to be cleaned is placed inside the clamping block 41, and the object to be cleaned is limited and fixed.

[0032] The electric slider moves on the electric slide rail 2, which moves the bracket 3 and the object to be cleaned fixed on it to a suitable cleaning position. The crossbar, inclined plate 31 and vertical plate 32 in the bracket 3 together form a stable support structure to ensure the stability of the object during the movement. The liquid pump is started, and the cleaning liquid in the liquid storage tank 51 is pumped to the connecting pipe 52 through the liquid pump, then flows into the fixed pipe 53, and finally sprays out from the nozzle 54 to clean the object to be cleaned.
