[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "higher," "lower," "top," and "bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. "Inner" and "outer" refer to the inner and outer contours of the corresponding component. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0027] For ease of understanding, please refer to the appendix below. Figures 1 to 2 The specific structure and working principle of the oil seal pressure head tooling disclosed herein will be described in detail with reference to the embodiments.

[0028] This disclosure relates to an oil seal press head fixture, which ensures that the movement path of the oil seal does not deviate during the press-fitting process, thus guaranteeing the installation effect of the oil seal. See also Figure 1 and Figure 2 The oil seal press head fixture disclosed herein includes an abutment part 1 and a force-bearing part 2. The abutment part 1 is provided with an abutment surface 11, which contacts the oil seal during press-fitting to drive the oil seal to move and complete the installation. A guide groove 12 is also provided on the abutment surface 11. The oil seal is annular, and the mating shaft of the oil seal can pass through the central hole of the oil seal and be inserted into the guide groove 12. The extension direction of the mating shaft and the guide groove 12 is the same as the installation direction of the oil seal. Therefore, after the mating shaft is inserted into the guide groove 12, it can guide the movement direction of the oil seal press head fixture and the oil seal to ensure that the oil seal can be installed smoothly without deviation, which could lead to reinstallation or damage to the oil seal. The force-receiving part 2 is connected to the abutting part 1 via the gripping rod 3. When in use, the operator can hold the gripping rod 3 and apply force to the force-receiving part 2 manually or mechanically. The force-receiving part 2 and the gripping rod 3 can then transmit the force to the abutting part 1, so that the oil seal can be moved by the abutting surface 11 that contacts the oil seal to complete the installation.

[0029] The oil seal pressure head fixture disclosed herein has a guide groove 12 on the contact surface 11, which allows the mating shaft of the oil seal to be inserted into the guide groove 12 during oil seal installation. This guides the movement direction of the fixture and the oil seal, preventing the oil seal from shifting during installation, thereby improving installation efficiency and ensuring installation stability.

[0030] In one embodiment of this disclosure, see Figure 1 and Figure 2 The oil seal pressure head fixture of this disclosure is I-shaped, with the abutment part 1 and the force-receiving part 2 arranged parallel to each other. The holding rod 3 is perpendicular to the abutment part 1 and the force-receiving part 2 and is fixedly connected to their opposing surfaces. This arrangement facilitates the operator's grip and installation with the oil seal. The opening of the guide groove 12 is provided on the abutment surface 11 so that the mating shaft can be inserted into the guide groove 12 through the abutment surface 11. The mating shaft is mostly straight. In this embodiment, the guide groove 12 also extends vertically away from the abutment surface 11 to better adapt to the mating shaft. Of course, in other embodiments, the oil seal pressure head fixture and the guide groove 12 can also be other shapes, depending on the actual situation. This disclosure does not limit this.

[0031] In one embodiment of this disclosure, see Figure 1 and Figure 2 A limiting surface 13 is also provided on the abutting part 1. The abutting surface 11 protrudes from the limiting surface 13 to facilitate cooperation with the oil seal. If the abutting surface 11 does not protrude from the limiting surface 13, the oil seal may be difficult to install properly in the portion between the abutting surface 11 and the limiting surface 13. By providing the limiting surface 13, the pressing depth of the oil seal can be limited, preventing damage caused by excessive pressing depth or insufficient pressing depth that fails to achieve a sealing effect.

[0032] In one embodiment of this disclosure, see Figure 1 and Figure 2 The abutment portion 1 is cylindrical to facilitate its adaptation to the annular oil seal. One side of the abutment portion 1 is connected to the gripping rod 3, while the outer periphery of the other side is provided with an annular stepped groove 14. The groove surface of the stepped groove 14 forms a limiting surface 13, and the end face of the abutment portion 1 with the stepped groove 14 forms an abutment surface 11 to ensure that the abutment surface 11 protrudes from the limiting surface 13. In this embodiment, the diameter of the abutment surface 11 is larger than the diameter of the oil seal to ensure that when the oil seal abuts against the abutment surface 11, the edge of the oil seal will not pass through the abutment surface 11 and contact the limiting surface 13.

[0033] Specifically, during use, the oil seal is first placed in the installation position. Then, the operator aligns the abutment surface 11 with the end face of the oil seal. Force is then applied manually or mechanically to the force-bearing part 2, causing the abutment part 1 to move the oil seal via the abutment surface 11 for installation. As the oil seal continues to move, the limiting surface 13 contacts the end face of the mating part to which the oil seal needs to be installed, at which point the oil seal installation is complete. In some other embodiments, the oil seal pressure head fixture of this disclosure provides space for the oil seal's rebound by controlling the distance between the limiting surface 13 and the abutment surface 11, thus enabling better installation. Specifically, the distance between the limiting surface 13 and the abutment surface 11 allows the oil seal to have a deeper installation distance than the suitable installation position after installation, thereby preventing the oil seal from springing out of the suitable installation position due to its own elasticity after installation.

[0034] In one embodiment of this disclosure, see Figure 1 and Figure 2 A connecting post 15 protruding from the contact surface 11 is provided on the contact surface 11. The diameter of the connecting post 15 is adapted to the inner ring of the oil seal, so that when the contact surface 11 abuts against the oil seal, the connecting post 15 can be inserted into the inner ring of the oil seal, further ensuring the stability of the oil seal during movement and preventing the oil seal from shifting during movement. In some other embodiments of this disclosure, an annular anti-slip pad 151 is also provided on the outer wall of the connecting post 15. The annular anti-slip pad 151 can ensure the stability of the connection after the connecting post 15 is installed into the oil seal, so that the oil seal can be fitted onto the connecting post 15 before installation to facilitate subsequent installation.

[0035] In one embodiment of this disclosure, see Figure 1 and Figure 2 The force-receiving part 2 is cylindrical, with one side connected to the holding rod 3 and the other side provided with a pressing surface 21. The pressing surface 21 facilitates the application of force to the force-receiving part 2 by the operator, thereby moving the oil seal to complete the installation. In some other embodiments, a flexible pad 211 is also provided on the pressing surface 21. This flexible pad 211 provides some protection to the force-receiving part 2 when the operator applies force, thus increasing the service life of the oil seal pressure head tooling of this disclosure. Of course, in other embodiments, the force-receiving part 2 can also have other structures, depending on the actual situation; this disclosure does not impose any limitations on this.

[0036] In one embodiment of this disclosure, see Figure 1 and Figure 2 Figure 1 Figure 2 The grip rod 3 is a round rod, which is convenient for staff to grip. The outer wall of the grip rod 3 is also provided with anti-slip texture 31, which makes it difficult for staff to slip off the grip rod 3 when they grip it tightly.

[0037] When using the oil seal pressure head fixture disclosed herein, the oil seal to be installed can first be fitted onto the connecting post 15 on the contact surface 11, so that the annular anti-slip pad 151 on the connecting post 15 can contact the inner wall of the oil seal. Then, the oil seal is placed in the installation position, and the operator applies force to the pressing plane 21 of the force-bearing part 2, so that the contact surface 11 can drive the oil seal to move for installation. As the oil seal moves, it continues until the limiting surface 13 on the contact part 1 contacts the end face of the oil seal mating part, thus completing the installation of the oil seal.

[0038] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0040] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
