Description

Technical Field

[0001] This utility model belongs to the technical field of grease injection equipment, specifically relating to a quantitative grease injection device for the inner cavity of a wheel hub. Background Technology

[0002] Wheel hub bearings play a crucial role in vehicle operation and require proper lubrication to reduce friction and wear. Precise grease injection ensures that the bearings within the wheel hub cavity receive an appropriate amount and uniform amount of grease, forming an effective lubricating film. This reduces direct contact between metal parts, thereby decreasing frictional heat generation, extending bearing life, and ensuring vehicle safety and reliability. Accurately injecting the right amount of high-quality grease during installation, combined with a good sealing structure, eliminates the need for additional grease injection throughout the vehicle's lifespan, reducing maintenance costs and downtime.

[0003] Traditional grease injection machines require frequent manual loading and unloading of wheel hubs during the grease injection process. Loading and unloading require controlling the opening and closing of the equipment, which reduces the grease injection efficiency and makes it inconvenient to grease wheel hubs of different sizes, thus reducing the applicability of the equipment. Utility Model Content

This solves the problem mentioned in the background art that the grease injection machine requires frequent manual loading and unloading of the wheel hub during the grease injection process. The loading and unloading require controlling the opening and closing of the equipment, which reduces the grease injection efficiency of the equipment and makes it inconvenient to perform grease injection work on wheel hubs of different sizes, thus reducing the applicability of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wheel hub inner cavity quantitative grease injection device, comprising a worktable, a rotating disk with a circular top and fixed cylinders fixedly connected to it, clamping plates symmetrically arranged inside the fixed cylinders, fixed blocks symmetrically fixedly connected to the top of the worktable, a movable plate on the top of the worktable, a grease storage tank fixedly connected to the top of the movable plate, a discharge pipe fixedly connected to the bottom of the grease storage tank, a plurality of discharge ports circularly arranged at the lower end of the discharge pipe, a rotating shaft rotatably connected inside the movable plate, an electric push rod fixedly connected to one side of the lower end of the rotating shaft, and an applicator plate fixedly connected to the output end of the electric push rod.

[0012] Compared with the prior art, this utility model provides a quantitative grease injection device for the inner cavity of a wheel hub, which has the following beneficial effects:

[0013] 1. This utility model features a rotating disk with multiple fixed cylinders mounted on its top. The wheel hub is placed inside the fixed cylinders, and the clamping plate moves within the fixed cylinders due to the force generated by the springs. This allows for the clamping and fixing of wheel hubs of different sizes. The structure is simple and stable, facilitating the installation and removal of wheel hubs.

[0014] 2. This utility model features an electric push rod and a spreading plate that extend into the grease-injected wheel hub under the push of a cylinder. The electric push rod then moves the spreading plate to contact the inner side of the wheel hub. Next, a second motor drives the rotating shaft to rotate, causing the spreading plate to rotate inside the wheel hub. This process evenly squeezes and spreads the injected grease into the inner cavity of the wheel hub, improving the grease injection effect and ensuring the service life of the wheel hub.

[0025] In this utility model, preferably, the bottom of the rotating disk 2 is fixedly connected to the output end of the first motor 3, and the first motor 3 is fixedly connected to the bottom of the worktable 1.

[0026] In this utility model, preferably, a sliding rod 6 is fixedly connected to one side of the clamping plate 5, and the sliding rod 6 and the fixed cylinder 4 are slidably connected. A spring 7 is fixedly connected between one side of the clamping plate 5 and the inner side of the fixed cylinder 4. A buffer pad 8 is fixedly connected to the top of the fixed cylinder 4. The wheel hub is placed inside the fixed cylinder 4, and the clamping plate 5 is pushed to move inside the fixed cylinder 4 by the force generated by the spring 7, so as to clamp and fix wheel hubs of different sizes. The structure is simple and stable, and it is convenient for the installation and disassembly of the wheel hub.

[0027] In this utility model, preferably, a signal transmitter 9 is fixedly connected to one side of the fixed cylinder 4, and a signal receiver 11 is fixedly connected to one side of the fixed block 10. The signal transmitter 9 and the signal receiver 11 send and receive signals to ensure the accuracy of the position of the fixed cylinder 4 during grease injection and improve the precision of grease injection.

[0028] In this utility model, preferably, a cylinder 13 is fixedly connected to the bottom of the movable plate 12, and the output end of the cylinder 13 is fixedly connected to the top of the fixed block 10.

[0029] In this utility model, preferably, a quantitative control valve 16 is provided on the outside of the discharge pipe 15, and a pressure plate 17 is fixedly connected to the lower end of the outside of the discharge pipe 15, and a sealing gasket 18 is fixedly connected to the bottom of the pressure plate 17.

[0030] In this invention, preferably, the top end of the rotating shaft 20 is connected to the output end of the second motor 21. The electric push rod 22 pushes the coating plate 23 to move and contact the inner side of the hub. Then, the second motor 21 drives the rotating shaft 20 to rotate, so that the coating plate 23 rotates inside the hub, and evenly squeezes and applies the grease injected into the hub cavity, thereby improving the grease injection effect of the equipment and ensuring the service life of the hub.

[0031] The working principle and usage process of this utility model are as follows: First, the wheel hub is placed inside the fixed cylinder 4. The force generated by the spring 7 pushes the clamping plate 5 to move inside the fixed cylinder 4, thus clamping and fixing wheel hubs of different sizes. The structure is simple and stable, facilitating the installation and removal of the wheel hub. Then, the first motor 3 drives the rotating disk 2 to rotate. During this process, the signal transmitter 9 emits a signal. When the signal receiver 11 receives the signal, it indicates that the fixed cylinder 4 is positioned directly below the discharge pipe 15. The signal is transmitted to the control mechanism, which controls the first motor 3 to shut off, stopping the rotating disk 2 and ensuring the accuracy of the fixed cylinder 4 position during grease injection, thus improving the precision of grease injection. Then, the cylinder 13 pulls the moving plate 12 downwards. At this time, the bottom of the discharge pipe 15 extends into the wheel hub. By controlling the quantitative control valve 16, quantitative delivery of lubricating grease is achieved. During the grease injection process, pressure... The sealing gasket 18 at the bottom of plate 17 contacts the buffer pad 8 to form a sealed environment, preventing grease leakage and contamination of the external environment during grease injection. Similarly, the cyclic rotation of the rotating disk 2 enables continuous grease injection of the wheel hub. When the greased wheel hub is placed directly below the rotating shaft 20, the electric push rod 22 and the spreading plate 23 are pushed into the inside of the greased wheel hub by the cylinder 13. Then, the electric push rod 22 pushes the spreading plate 23 to move and contact the inside of the wheel hub. Next, the second motor 21 drives the rotating shaft 20 to rotate, causing the spreading plate 23 to rotate inside the wheel hub, evenly squeezing and spreading the injected grease into the inner cavity of the wheel hub, improving the grease injection effect of the equipment, ensuring the service life of the wheel hub, and the overall structure can meet the grease injection needs of wheel hubs of different sizes, increasing the applicability of the equipment, and enabling the loading and unloading of wheel hubs without affecting the grease injection process, thereby improving the grease injection efficiency of the equipment.
