Description

Technical Field

[0001] This utility model belongs to the technical field of motor shaft processing equipment, and in particular relates to a cleaning device for motor shaft production. Background Technology

[0002] During the production process of motor shafts, after multiple processing steps such as cutting, grinding, and heat treatment, impurities such as metal shavings, cutting fluid residue, and oil stains inevitably adhere to their surface. If these impurities are not thoroughly removed, they will not only affect the fitting accuracy between the motor shaft and components such as bearings and rotors during subsequent assembly, leading to problems such as abnormal noise and vibration during motor operation, but may also accelerate corrosion on the surface of the motor shaft, shortening the overall service life of the motor.

[0003] Chinese patent application CN217550547U discloses a motor shaft cleaning device, including a water tank storing cleaning fluid, parallel sliding rails fixed to the bottom of the water tank, and a slider base. An inverted U-shaped bracket is fixedly installed on the end side wall of the slider base. This invention has a simple structure. After the motor shaft is placed on the bracket, the movement of the slider base allows the roller brush to be paired with the shaft hole of the motor shaft. The motor drives the roller brush to rotate, simultaneously cleaning the entire inner wall of all motor shafts in the water tank, saving cleaning time and greatly improving cleaning efficiency.

[0004] The aforementioned device cleans by rotating a roller brush in the cleaning solution, but it cannot achieve dynamic cleaning of the motor shaft during movement. This may result in some areas not being cleaned properly. Furthermore, there is no dedicated drying mechanism in the post-cleaning process, leaving cleaning solution residue on the surface of the motor shaft. If not dried in time, this residue can easily re-adhere to impurities and may also cause short-term corrosion on the surface of the motor shaft, affecting subsequent processing or assembly progress.

[0005] To address these issues, we provide a cleaning device for motor shaft manufacturing. Utility Model Content

[0006] The purpose of this utility model is to provide a cleaning device for motor shaft production. By cooperating with a quick positioning mechanism, a cleaning mechanism and a drying mechanism, it solves the problems of existing cleaning devices being unable to achieve dynamic cleaning of motor shafts during movement, potentially resulting in inadequate cleaning of some areas, and the lack of a dedicated drying mechanism.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a cleaning device for motor shaft production, comprising a frame, an inner cavity of which is provided with a conveyor belt, a quick positioning mechanism fixedly connected to the top of the conveyor belt, a cleaning mechanism on one side of the top of the frame, and a drying mechanism on the other side of the top of the frame. The quick positioning mechanism includes a mounting frame, the bottom of which is fixedly connected to the conveyor belt, and a shaft on the top of the mounting frame. Grooves adapted to the shaft are formed on both sides of the top of the mounting frame. A drive motor is fixedly connected to one side of the mounting frame, and a rotating rod is fixedly connected to the output end of the drive motor. Rotating rollers are fixedly connected to both sides of the rotating rod, with the top of the rotating rollers contacting the shaft. After the drive motor starts, it drives the rotating rod to rotate around the shaft. The shaft rotates along its axis, with the rotating roller and rotating rod rotating coaxially. The two rotating rollers correspond to the grooves on both sides of the top of the mounting frame. When the rotating rollers rotate, the friction between them and the shaft drives the shaft to rotate around its own axis. The conveyor belt drives the quick positioning mechanism and the shaft to move along the length of the frame, ensuring that the shaft can pass through the cleaning and drying processes in an orderly manner. This avoids the inefficiency and positional deviation caused by manual handling. The grooves on both sides of the mounting frame are adapted to the shaft, effectively limiting the lateral displacement of the shaft. Combined with the contact support between the rotating rollers and the shaft, the shaft maintains a stable posture during the conveying process. The drive motor drives the rotating rollers to rotate through the rotating rod, which in turn drives the shaft to rotate, achieving dynamic positioning of the shaft during the conveying process and ensuring a comprehensive cleaning effect for the shaft.

[0009] The present invention is further configured such that the cleaning mechanism includes a housing, the bottom of which is fixedly connected to a frame, a connecting frame is fixedly connected to the bottom of the housing, an electric push rod is fixedly connected to the top of the connecting frame, and a cleaning roller is fixedly connected to the bottom of the electric push rod. The electric push rod adjusts the height of the cleaning roller and controls the contact pressure between the cleaning roller and the surface of the shaft according to the diameter of the shaft or the surface cleaning requirements. When the shaft diameter is large or the surface impurities are stubborn, the height of the cleaning roller is lowered by the electric push rod to increase the contact pressure and enhance the cleaning effect. When the shaft diameter is small or the surface needs to avoid excessive friction, the height of the cleaning roller is raised to reduce the contact pressure and prevent damage to the shaft surface.

[0010] The present invention is further configured such that the drying mechanism includes a fixed plate, one side of which is fixedly connected to the frame, and a spray pipe is fixedly connected to one side of the fixed plate. A heating box is fixedly connected to one side of the top of the frame, and a fan is fixedly connected to the top of the heating box. When the shaft moves with the conveyor belt to below the spray pipe, the spray pipe can spray clean water onto the surface of the shaft to quickly wash away the loose metal debris attached to the surface of the shaft. The heating box and the fan work together with the spray pipe to complete the drying process after cleaning.

[0011] The present invention is further configured such that connecting blocks are fixedly connected to both sides of the frame, and a wastewater collection tank is fixedly connected to the bottom of the connecting blocks. The wastewater collection tanks fixed to both sides of the frame through the connecting blocks realize the centralized collection and management of wastewater during the cleaning process.

[0012] The present invention is further configured such that the conveyor belt is a plate-type conveyor plate, and the number of mounting frames corresponds to the number of the conveyor belt. Compared with the traditional belt conveyor, the plate-type conveyor plate has a stronger load-bearing capacity and stability, avoids the shaft position shift caused by the deformation of the conveyor belt during the transmission process, and ensures that the shaft is smoothly transported along the preset path. Each mounting frame holds one shaft, realizing the synchronous transport and continuous processing of multiple shafts.

[0013] The present invention is further provided that the surface of the rotating roller is covered with an anti-slip sleeve, and the surface of the anti-slip sleeve is provided with protrusions. The anti-slip sleeve and the protrusions on the surface of the rotating roller increase the friction between the rotating roller and the shaft, effectively solving the slippage problem that may occur when the rotating roller drives the shaft to rotate.

[0014] The present invention is further configured such that a connector is connected to one side of the spray pipe, and one side of the connector is connected to an external water supply device. When there are many impurities on the surface of the shaft that are difficult to be completely removed by the cleaning roller alone, the external water supply device is connected through the connector so that the spray pipe sprays clean water onto the surface of the shaft, thereby improving the overall cleaning effect.

[0015] The present invention is further configured such that a movable groove is provided at the bottom of the groove, and the rotating roller is disposed in the inner cavity of the movable groove. The movable groove provides a reasonable installation space for the rotating roller, allowing the rotating roller to be embedded in the inner cavity of the movable groove and to contact the shaft body, thus avoiding the rotating roller from being installed too high, causing the shaft body to be unstable, or being too low, preventing it from effectively contacting the shaft body.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model uses a drive motor to drive a rotating rod to rotate. The rotating roller on the surface of the rotating rod drives the shaft to rotate at a constant speed around its own axis by friction. This makes the shaft no longer have a fixed orientation during the cleaning process. As it rotates, it continuously contacts the cleaning components, ensuring that the cleaning components can cover all surfaces of the shaft, thus completely solving the problem of partial omissions in traditional fixed shaft cleaning.

[0018] 2. This utility model adjusts the contact pressure between the cleaning roller and the shaft surface through an electric push rod. It can not only quickly remove metal debris from the shaft surface, but also, compared with the traditional cleaning method that relies on the unidirectional movement of the cleaning components while the shaft is fixed, the rotation of the shaft expands the effective range of the cleaning roller from a local linear area to the entire circumference. This avoids over-cleaning of the shaft or insufficient cleaning of the shaft leaving impurities. When the shaft rotates, the spray nozzle can evenly spray the cleaning water onto the shaft surface. The drying mechanism can quickly remove the residual moisture after cleaning and prevent secondary pollution caused by local dampness due to the stationary shaft. Attached Figure Description

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5This utility model is a cleaning device for motor shaft production, including a frame 1, a conveyor belt 2 is provided in the inner cavity of the frame 1, a quick positioning mechanism 3 is fixedly connected to the top of the conveyor belt 2, a cleaning mechanism 4 is provided on one side of the top of the frame 1, and a drying mechanism 5 is provided on the other side of the top of the frame 1. The quick positioning mechanism 3 includes a mounting frame 31, the bottom of the mounting frame 31 is fixedly connected to the conveyor belt 2, a shaft body 32 is provided on the top of the mounting frame 31, and grooves 33 adapted to the shaft body 32 are provided on both sides of the top of the mounting frame 31. A drive motor 34 is fixedly connected to one side of the mounting frame 31, a rotating rod 35 is fixedly connected to the output end of the drive motor 34, and rotating rollers 36 are fixedly connected to both sides of the surface of the rotating rod 35. The top of the rotating rollers 36 is in contact with the shaft body 32.

[0028] Specifically: After the drive motor 34 starts, it drives the rotating rod 35 to rotate around its own axis. The rotating roller 36 rotates coaxially with the rotating rod 35, and the two rotating rollers 36 correspond to the grooves 33 on both sides of the top of the mounting frame 31. When the rotating roller 36 rotates, it drives the shaft 32 to rotate around its own axis by means of the friction between the roller and the shaft 32. The conveyor belt 2 drives the quick positioning mechanism 3 and the shaft 32 to move along the length of the frame 1, ensuring that the shaft 32 can pass through the cleaning and drying process in an orderly manner, avoiding the inefficiency and positional deviation caused by manual handling. The grooves 33 on both sides of the mounting frame 31 are adapted to the shaft 32, which can effectively limit the lateral displacement of the shaft 32. With the contact support between the rotating roller 36 and the shaft 32, the shaft 32 always maintains a stable posture during the conveying process. The drive motor 34 drives the rotating roller 36 to rotate through the rotating rod 35, thereby driving the shaft 32 to rotate, realizing the dynamic positioning of the shaft 32 during the conveying process, and ensuring the all-round cleaning effect of the shaft 32.

[0029] The cleaning mechanism 4 includes a housing 41, the bottom of which is fixedly connected to the frame 1. A connecting frame 42 is fixedly connected to the bottom of the housing 41, and an electric push rod 43 is fixedly connected to the top of the connecting frame 42. A cleaning roller 44 is fixedly connected to the bottom of the electric push rod 43. The drying mechanism 5 includes a fixing plate 51, one side of which is fixedly connected to the frame 1. A spray pipe 52 is fixedly connected to one side of the fixing plate 51. A heating box 53 is fixedly connected to one side of the top of the frame 1. A fan 54 is fixedly connected to the top of the heating box 53. Connecting blocks 6 are fixedly connected to both sides of the frame 1. A wastewater collection box 7 is fixedly connected to the bottom of the connecting blocks 6. The conveyor belt 2 is a plate conveyor plate. The number of mounting frames 31 corresponds to the number of conveyor belts 2. An anti-slip sleeve is fitted on the surface of the rotating roller 36. The surface of the anti-slip sleeve is provided with protrusions. A connector 8 is connected to one side of the spray pipe 52. One side of the connector 8 is connected to an external water supply device. A movable groove 9 is opened at the bottom of the groove 33. The rotating roller 36 is located in the inner cavity of the movable groove 9.

[0030] Specifically: The electric push rod 43 adjusts the height of the cleaning roller 44, controlling the contact pressure between the cleaning roller 44 and the surface of the shaft 32 according to the diameter of the shaft 32 or the surface cleaning requirements. When the diameter of the shaft 32 is large or the surface impurities are stubborn, the electric push rod 43 lowers the height of the cleaning roller 44 to increase the contact pressure and enhance the cleaning effect. When the diameter of the shaft 32 is small or the surface needs to avoid excessive friction, the height of the cleaning roller 44 is raised to reduce the contact pressure and prevent damage to the surface of the shaft 32. When the shaft 32 moves with the conveyor belt 2 to below the spray nozzle 52, the spray nozzle 52 sprays clean water onto the surface of the shaft 32, quickly washing away loose metal debris attached to the surface of the shaft 32. The heating box 53 and the fan 54 work with the spray nozzle 52 to complete the drying process after cleaning. Wastewater collection boxes 7, fixed on both sides of the frame 1 by connecting blocks 6, realize the centralized collection and management of wastewater during the cleaning process. Compared with the traditional belt conveyor 2, the plate conveyor has stronger... The load-bearing capacity and stability prevent the shaft 32 from shifting due to deformation of the conveyor belt 2 during transmission, ensuring that the shaft 32 is smoothly conveyed along the preset path. Each mounting frame 31 holds one shaft 32, realizing synchronous conveying and continuous processing of multiple shafts 32. The anti-slip sleeve and surface protrusions on the surface of the rotating roller 36 increase the friction between the rotating roller 36 and the shaft 32, effectively solving the slippage problem that may occur when the rotating roller 36 drives the shaft 32 to rotate. When there are many impurities on the surface of the shaft 32, which are difficult to be completely removed by the cleaning roller 44 alone, the external water supply equipment is connected through the connector 8, so that the spray pipe 52 sprays clean water onto the surface of the shaft 32, improving the overall cleaning effect. The movable groove 9 provides a reasonable installation space for the rotating roller 36, allowing the rotating roller 36 to be embedded in the inner cavity of the movable groove 9 and contact the shaft 32, avoiding the instability of the shaft 32 due to the rotating roller 36 being installed too high, or the inability to effectively contact the shaft 32 due to the position being too low.

[0031] The working principle of this utility model is as follows: The shaft 32 to be cleaned is placed on the top of the mounting frame 31. The grooves 33 on both sides of the mounting frame 31 are adapted to the shaft 32 to initially limit the lateral movement of the shaft 32 and prevent the shaft 32 from shifting left and right before conveying. The drive motor 34 is started, and the drive motor 34 drives the rotating rod 35 to rotate around its own axis. The rotating rod 35 synchronously drives the rotating rollers 36 on both sides to rotate. When the shaft 32 moves with the conveyor belt 2 to the bottom of the spray pipe 52, the external water supply equipment delivers clean water to the spray pipe 52 through the connector 8. The spray pipe 52 sprays clean water onto the surface of the rotating shaft 32. The rotation of the shaft 32 allows the clean water to evenly cover its circumference.

[0032] After completing the water-assisted cleaning, the shaft 32 continues to move along the conveyor belt 2 to the bottom of the cleaning mechanism 4. Depending on the diameter of the shaft 32 or the condition of the surface impurities, if the diameter of the shaft 32 is large or the impurities are stubborn, the electric push rod 43 extends, driving the bottom cleaning roller 44 to descend, increasing the contact pressure between the cleaning roller 44 and the surface of the shaft 32. If the diameter of the shaft 32 is small or the surface needs to be protected, the electric push rod 43 shortens, driving the cleaning roller 44 to rise, reducing the contact pressure. At this time, the shaft 32 is still rotating. The dynamic friction between the cleaning roller 44 and the shaft 32 can thoroughly remove the residual oil and fine impurities on the surface of the shaft 32, achieving all-round deep cleaning.

[0033] Once the cleaned shaft 32 has moved along the conveyor belt 2 to the bottom of the heating box 53, the heating box 53 and the fan 54 are started. The heating box 53 steadily generates heat, and the fan 54 runs to convert the heat in the heating box 53 into hot air, which is then blown evenly onto the surface of the shaft 32, which is still rotating. The rotation of the shaft 32 allows the hot air to cover all its surfaces, quickly removing any residual moisture.

[0034] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
