Description

Technical Field

[0001] This utility model belongs to the field of engine pump hub technology, specifically relating to an engine pump hub with lubrication function. Background Technology

[0002] The engine pump hub is a key component of pump equipment, used to mount the impeller and transmit power. It is typically made of cast iron or aluminum alloy and must possess sufficient strength and wear resistance. The hub connects to the pump shaft via a key or interference fit. The surface finish affects operational stability. Commonly used in automotive cooling systems and industrial fluid transport, it plays a crucial supporting role in the overall performance of the pump.

[0003] Currently, engine pump hubs have the following problems: when lubricating oil is sprayed onto the workpiece surface, it cannot be evenly coated, and the friction in the unlubricated areas increases, leading to abnormal wear at the connection between the hub and the shaft or impeller, and shortening the life of the components. Therefore, we propose an engine pump hub with lubrication function. Utility Model Content

[0004] The purpose of this invention is to provide an engine pump hub with a lubrication function, which can solve the problem in the related technology that when the engine pump hub is sprayed with lubricating oil, the workpiece surface cannot be uniformly sprayed, the friction of the unlubricated area increases, resulting in abnormal wear at the connection between the hub and the shaft or impeller, and shortening the service life of the component.

[0005] The specific technical solution adopted by this utility model is as follows: An engine pump hub with lubrication function includes a worktable, an even spraying device provided on the inner wall of the worktable, the even spraying device including a rotating component, a liquid storage tank fixedly connected to the top of the worktable, a water pipe fixedly connected to the top of the liquid storage tank, a pressing component fixedly connected to the side of the liquid storage tank, a fixed cylinder rotatably connected to the top of the worktable, a nozzle fixedly connected to the inner wall of the fixed cylinder, and the end of the water pipe away from the liquid storage tank fixedly connected to the top of the fixed cylinder.

[0006] The rotating assembly includes a turntable, the outer wall of which is rotatably connected to the inner wall of the worktable. The turntable is driven by a motor, and the top of the motor is fixedly connected to the bottom of the turntable. The workpiece body is placed on the top of the turntable. When the motor is started, the output shaft of the motor rotates, causing the turntable to rotate. The rotation of the turntable causes the workpiece body to rotate. At the same time, the pressing component is activated, which controls the lubricating oil in the reservoir to be sprayed out through the nozzle.

[0007] The pressing component is used to control the lubricating fluid in the reservoir to be sprayed out through the nozzle, and a one-way inlet is fixedly connected to the side of the reservoir.

[0008] A gap is provided between the workpiece body and the nozzle, and six sets of nozzles are arranged in a circumferential array on the inner wall of the fixed cylinder.

[0009] A coating device is provided on the circumferential surface of the fixed cylinder. The coating device includes a threaded rod that passes through and is threaded onto the circumferential surface of the fixed cylinder. A nut is fixedly connected to one end of the threaded rod, and a coating plate is rotatably connected to the end of the threaded rod away from the nut. A circular groove is provided on the top of the workbench, and a guide tube is fixedly connected to the bottom of the circular groove. A recycling bin is fixedly connected to the bottom of the workbench, and the end of the guide tube away from the workbench is fixedly connected to the side of the recycling bin. Before spraying begins, the operator twists the nut, which rotates the threaded rod, causing it to rotate. The rotation of the threaded rod causes the coating plate to move. After the coating plate contacts the workpiece, the uniform spraying device is activated.

[0010] The threaded rod and the nozzle are staggered, and the workpiece body is located on the movement trajectory of the coating plate.

[0011] The outer diameter of the annular groove is equal to the inner diameter of the fixed cylinder, and a gap is provided between the workpiece body and the fixed cylinder.

[0012] The technical effects achieved by this utility model are as follows: This invention utilizes a uniform spraying device to coordinate the motor, turntable, workpiece body, liquid storage tank, water pipe, pressing component, fixing cylinder, and spray nozzle. When the motor is started, its output shaft rotates, causing the turntable to rotate, which in turn rotates the workpiece body. Simultaneously, the pressing component is activated, controlling the lubricating oil in the liquid storage tank to be sprayed out through the spray nozzle. Because the workpiece body rotates, the lubricating oil can be sprayed more evenly onto its surface, preventing uneven spraying and increased friction in insufficiently lubricated areas, which can lead to abnormal wear at the hub-shaft or impeller connection and shorten component lifespan.

[0013] This invention utilizes a coating device that coordinates a threaded rod, nut, coating plate, annular groove, guide tube, and recycling bin. Before spraying begins, the operator twists the nut, causing the threaded rod to rotate. This rotation then moves the coating plate, which in turn moves it. Once the coating plate contacts the workpiece, the uniform spraying device is activated. The coating plate evenly coats the workpiece surface with lubricating oil. Excess lubricating oil flows into the annular groove and then through the guide tube into the recycling bin, preventing excess oil from accumulating and causing a fire. Centralized collection and storage ensures standardized management and reduces safety hazards. Attached Figure Description

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figures 1-5 As shown, an engine pump hub with lubrication function includes a workbench 1. The inner wall of the workbench 1 is provided with a uniform spraying device 2, which includes a rotating component. A liquid storage tank 24 is fixedly connected to the top of the workbench 1. A water pipe 25 is fixedly connected to the top of the liquid storage tank 24. A pressing component 26 is fixedly connected to the side of the liquid storage tank 24. A fixed cylinder 27 is rotatably connected to the top of the workbench 1. A nozzle 28 is fixedly connected to the inner wall of the fixed cylinder 27. The end of the water pipe 25 away from the liquid storage tank 24 is fixedly connected to the top of the fixed cylinder 27.

[0018] The rotating assembly includes a turntable 22, the outer wall of which is rotatably connected to the inner wall of the worktable 1. The turntable 22 is driven by a motor 21, and the top of the motor 21 is fixedly connected to the bottom of the turntable 22. The workpiece body 23 is placed on the top of the turntable 22.

[0019] The pressing element 26 is used to control the lubricating fluid in the reservoir 24 to be sprayed out through the nozzle 28. A one-way inlet is fixedly connected to the side of the reservoir 24 for replenishing the lubricating oil.

[0020] A gap is provided between the workpiece body 23 and the nozzle 28 to avoid motion interference and damage to the workpiece body 23. The nozzle 28 is provided in six sets and is arranged in a circumferential array on the inner wall of the fixed cylinder 27 to ensure uniform spraying of lubricating oil. According to the above structure, the motor 21 is started, and the output shaft of the motor 21 rotates, which drives the turntable 22 to rotate. The rotation of the turntable 22 drives the workpiece body 23 to rotate. At the same time, the pressing component 26 is activated, and the pressing component 26 controls the lubricating oil in the liquid storage tank 24 to be sprayed out through the nozzle 28. As the workpiece body 23 rotates, the lubricating oil can be sprayed more evenly on the surface of the workpiece body 23, avoiding uneven spraying on the surface of the workpiece body 23, which would increase friction in areas that are not fully lubricated, leading to abnormal wear at the connection between the hub and the shaft or impeller, and shortening the life of the component.

[0021] like Figures 1-5 As shown, a coating device 3 is provided on the circumferential surface of the fixed cylinder 27. The coating device 3 includes a threaded rod 31, which passes through and is threadedly connected to the circumferential surface of the fixed cylinder 27. A nut 32 is fixedly connected to one end of the threaded rod 31, and a coating plate 33 is rotatably connected to the other end of the threaded rod 31 away from the nut 32. A circular groove 34 is provided on the top of the workbench 1, and a conduit 35 is fixedly connected to the bottom of the circular groove 34. A recycling box 36 is fixedly connected to the bottom of the workbench 1, and the other end of the conduit 35 away from the workbench 1 is fixedly connected to the side of the recycling box 36.

[0022] The threaded rod 31 and the nozzle 28 are staggered to avoid motion interference and damage to parts. The workpiece body 23 is located on the motion trajectory of the coating plate 33.

[0023] The outer diameter of the annular groove 34 is equal to the inner diameter of the fixed cylinder 27, and a gap is provided between the workpiece body 23 and the fixed cylinder 27 to avoid motion interference; According to the above structure, before spraying begins, the worker twists the nut 32. The rotation of the nut 32 causes the threaded rod 31 to rotate, which in turn moves the coating plate 33. After the coating plate 33 contacts the workpiece body 23, the uniform spraying device 2 is activated. The coating plate 33 can evenly coat the lubricating oil on the surface of the workpiece body 23. Excess lubricating oil will flow into the annular groove 34 and then flow into the recycling bin 36 through the conduit 35. This prevents excess lubricating oil from accumulating and causing a fire. Centralized collection and storage can standardize management and reduce safety hazards.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
