Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to a cleaning device for a bell housing of a drive shaft assembly. Background Art

[0002] The drive shaft assembly is an important component in the automobile transmission system, mainly used to transmit power. It is usually installed between the differential or the final reduction gear and the wheel hub. It is mainly composed of a drive shaft, a fixed ball cage universal joint and a telescopic ball cage universal joint. The fixed ball cage universal joint is composed of a bell-shaped shell, a cage (ball cage) and steel balls. The bell-shaped shell is also called an alien wheel. When processing the bell-shaped shell, cutting fluid and lubricating oil are used to reduce the cutting temperature and lubricate, and help remove chips. These liquids will leave yellow residual liquid during use, which gradually solidifies into stubborn oil stains. Therefore, the bell-shaped shell needs to be cleaned after milling to remove the oil stains on its surface to facilitate subsequent processing processes such as painting and fine grinding.

[0003] The current bell-shaped shell cleaning equipment is mainly composed of a transmission mechanism, a spray mechanism and a drying mechanism. After the bell-shaped shell is processed, it will be transported to the cleaning equipment and then cleaned during the transmission process. For example, the related technology (CN202129233U) discloses an alien wheel intermediate cleaning device, including a frame and an electrical box, a transmission shaft, a transmission motor and a water tank installed in the frame base. It also includes a spray system for cleaning the blank and a drying system for drying the blank. The spray system includes a water pump, water inlet and outlet pipes, and several water spray heads. The drying system includes a fan and at least one wind head. The blank installed on the workbench is first cleaned by the spray system under the drive of the transmission shaft, and then dried and removed by the drying system.

[0004] However, the flushing method is not comprehensive enough and is prone to cleaning blind spots. Most of the time, it can only clean some residual metal chips and unsolidified oil stains. The cleaning effect on some stubborn stains is not ideal, especially the raceway area inside the bell housing, which is often difficult to reach with water. Therefore, it is necessary to propose a bell housing cleaning device for a drive shaft assembly. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a driving shaft assembly bell housing cleaning device.

[0006] The present invention is implemented by the following technical scheme: a cylinder shell is provided with a feed port, a discharge port and a partition, and a transfer mechanism for transferring the bell-shaped shell and a cleaning mechanism for cleaning the bell-shaped shell are arranged in the cylinder shell; the transfer mechanism includes a shaft cylinder which is rotatable and can discharge wastewater in the cylinder shell, and a plurality of cleaning cylinders for placing the bell-shaped shell are rotatably mounted on the shaft cylinder; the cleaning mechanism includes a rotatable water injection pipe, one end of the water injection pipe extends to the outside of the cylinder shell and is rotatably connected to the cylinder shell, and a cover shell which can cover the cleaning cylinder and drive the cleaning cylinder to flip together is fixedly mounted on two branches of the water injection pipe, and a flippable second magnet, nickel sand for assisting in cleaning the bell-shaped shell, and a partition which can be raised and lowered and reset to separate the second magnet and the nickel sand are arranged in the cover shell.

[0007] As a further improvement of the above scheme, the top inner wall of the cylinder shell is provided with a material guide funnel opposite to the feed port, the bottom end of the material guide funnel is opposite to the corresponding cleaning cylinder, and the bottom of the partition is provided with a material guide groove opposite to the discharge port, so that the bell-shaped shell falling into the feed port can smoothly enter the cleaning cylinder through the material guide funnel, and can be discharged from the discharge port through the material guide groove after cleaning is completed.

[0008] As a further improvement of the above solution, an air duct is provided on one side of the cylinder shell, so that the cleaning device can be connected to an external hot air device to dry the bell-shaped shell transferred to this position after cleaning.

[0009] As a further improvement of the above solution, a first motor and a second motor are arranged in the cylinder shell, the first motor is transmission-connected to the shaft cylinder, and the second motor is transmission-connected to the water injection pipe.

[0010] As a further improvement of the above scheme, the cleaning cylinder consists of two parts: a cylinder body and a connecting pipe. A water outlet is arranged between the cleaning cylinder and the connecting pipe. A filter is arranged on the water outlet, so that the cleaning waste water can be introduced into the shaft cylinder for discharge. At the same time, the filter can also prevent the loss of nickel sand.

[0011] As a further improvement of the above solution, a first magnet with a repulsive surface facing the filter is further provided in the connecting pipe of the cleaning cylinder, so that the repulsive force of the first magnet can prevent nickel sand from approaching the water outlet and the filter.

[0012] As a further improvement of the above scheme, a partition structure is arranged in the shaft cylinder, and the partition structure is composed of a circular plate and a cross baffle arranged at the bottom of the circular plate, so that the cleaning waste water can not only be discharged into the shaft cylinder smoothly, but also will not mistakenly enter other cleaning cylinders and cause leakage.

[0013] As a further improvement of the above scheme, a sleeve is arranged on the partition, the shaft cylinder passes through the sleeve and is rotatably connected with the sleeve, a semi-toothed ring is arranged on the side of the top of the sleeve close to the discharge port, and the connecting pipes of multiple cleaning cylinders are all provided with a circular toothed ring that can be transmitted with the semi-toothed ring, so that the cleaning cylinder can be flipped over once in the process of passing through the discharge port area and returning to the feed port position, so as to pour out the cleaned bell-shaped shell.

[0014] As a further improvement of the above scheme, sliding rods are provided on both sides of the cover shell, and springs and connecting frames are sleeved on the two sliding rods. The two connecting frames extend into the cover shell and are fixedly connected to the partition, so that the partition will be subjected to downward force when the second magnet flips, and can automatically reset after the partition flip is completed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: A cleaning mechanism that allows nickel sand to cooperate with water is formed by a water injection pipe, a cover shell, a second magnet, and nickel sand arranged in the cover shell. It not only has the decontamination effect of traditional water washing equipment, but also can remove some stubborn attachments that are difficult to remove by grinding. It can not only clean the bell shell, but also grind the processed bell shell. At the same time, the entire water flow can form a rotating vortex in the cleaning cylinder. Combined with its flippable characteristics, it can further improve the cleaning effect of the bell shell, making the cleaning of the bell shell more comprehensive. By arranging a partition that can be raised and lowered and reset in the housing, the partition can not only be closely attached to the second magnet, but also keep a smaller distance between the nickel sand and the second magnet, so as to ensure that the nickel sand can be better stored in the housing without being lost under the magnetic attraction of the second magnet, and at the same time, the partition will not restrict the flipping of the second magnet (switching between the magnetic surface and the repulsive surface), and when the second magnet is converted to the repulsive surface, its repulsive force will also make the nickel sand more fully contact with the bell housing; By arranging a filter screen and a first magnet at the connecting pipe of the cleaning cylinder, the cleaning wastewater can be discharged smoothly without causing the nickel sand mixed in the wastewater to be lost. In addition, the repelling surface of the first magnet can prevent the nickel sand from approaching the filter screen, thereby avoiding clogging of the filter screen and affecting the discharge of wastewater.
