Technical Field
[0001] The utility model relates to the technical field of press-fitting, in particular to a wheel hub bearing oil seal press-fitting machine. Background Art
[0002] Oil seal is the customary name for general seals. Simply put, it is a seal for lubricating oil. It is a mechanical component used to seal grease. It isolates the parts that need lubrication in the transmission components from the output components to prevent the lubricating oil from leaking. The seals used for static and dynamic seals are called oil seals. Generally, a hydraulic press is required for installation.
[0003] The existing wheel hub bearing oil seal press machine needs to adjust the position of the workpiece in advance before press installation so that the oil seal can remain level with the workpiece during press installation. The existing method of adjusting the position of the workpiece generally adopts the relative position of the column and the base to ensure the verticality between the two, thereby achieving the horizontality of the oil seal and the workpiece. However, this adjustment method still has errors after the adjustment is completed, and it needs to be readjusted when it is worn, which consumes a lot of man-hours and is time-consuming and labor-intensive. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a wheel hub bearing oil seal press to solve the technical problem that a certain error still exists when adjusting the relative position of the column and the base to ensure the verticality between the two.

It not only improves the accuracy and efficiency of press-fitting, but also enhances the adaptability and reliability of the machine, making the press-fitting and removal process more efficient and smooth.
[0011] Furthermore, a clamping block is slidably connected inside the sliding groove, and a spring is provided between the clamping block and the cylindrical pin.
[0012] By adopting the above technical solution, the sliding connection of the block in the sliding groove provides an effective mechanical locking mechanism, so that the oil seal can be accurately positioned and fixed during the press-fitting process, and the cylindrical pin can be stably fixed to the connecting column, thereby ensuring the accuracy and quality of the assembly. At the same time, the presence of the spring increases the flexibility of this mechanism, allowing the block to automatically reset.
[0013] Furthermore, an unlocking rod is fixedly connected to the top of the table, and an inclined surface is provided on the top of the unlocking rod.
[0014] By adopting the above technical solution, the unlocking rod provides a fast and effective mechanical unlocking mechanism, so that after the pressing process is completed, the operator can easily and quickly release and remove the pressed workpiece.

[0015] Furthermore, the block is provided with an inclined groove, and the inclined groove and the inclined surface are matched.
[0016] By adopting the above technical solution, the design of the inclined groove provides an effective interface for the unlocking process, so that after the press-fitting is completed, the inclined surface of the unlocking rod can smoothly cooperate with the inclined groove to achieve smooth mechanical unlocking.
[0017] Furthermore, a motion groove is provided inside the table, and a pressure rod is slidably connected inside the motion groove.
[0018] By adopting the above technical solution, the motion groove provides a precise guide path for the pressure rod, ensuring that the pressure rod can move smoothly along a determined trajectory during the pressing process and ensuring the reliability of the fixing process. The pressure rod can apply pressure accurately as needed, thereby ensuring that the workpiece is reliably fixed.
[0019] Furthermore, two pressure rods are provided, the two pressure rods are arranged in a mirror image, and a tension spring is fixedly connected between the two pressure rods.
[0020] By adopting the above technical solution, the double pressure rod design enables the machine to apply uniform and symmetrical pressure on both sides of the workpiece at the same time, ensuring that the workpiece can be stably and correctly fixed. The addition of the tension spring maintains the synchronization and consistency between the two pressure rods, ensuring that they can work together during operation.

The design of the column 4 and the lifting platform 5 enables the pressing tool to move accurately in the vertical direction, which helps to achieve precise alignment during the pressing process. The presence of the positioning mechanism 6 and the sliding table 601 further enhances this precise alignment capability. They ensure the correct position and stability of the workpiece during the pressing process.
