[0002] An oil seal press-fitting fixture is a special tool used to precisely press oil seals onto mechanical parts. Through precise positioning and guiding functions, it ensures that the oil seal is not damaged during the press-fitting process, while guaranteeing its sealing performance.
[0003] Many oil seal press-fit fixtures need to be mounted on a tooling base to achieve accurate positioning and support. For example, Chinese patent CN211516595U discloses a box-type oil seal press-fit fixture, in which the positioning base is used to fix the oil seal seat to ensure the concentricity of the oil seal and the oil seal seat.
[0004] In the prior art, the press-fit fixture is installed on the tooling base. However, the press-fit fixture cannot be stored on the working base. The inability to store it will result in the equipment occupying too much space, and the exposed parts are easily damaged by collisions or contaminated with dust and oil, which will affect the positioning accuracy in the long term. At the same time, it will increase safety hazards and increase equipment maintenance costs. Therefore, a retractable housing oil seal press-fit fixture is proposed to solve the above problems.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1-3 This utility model provides an embodiment of a retractable housing oil seal press-fitting fixture, comprising a press-fitting fixture body 1. The press-fitting fixture typically uses positioning pins, clamps, or supports to precisely position the workpiece. Pressure is applied to the fixture by a cylinder, causing the pressed part to enter the target position according to predetermined assembly requirements. A base 2 is provided at the bottom of the press-fitting fixture body 1, and a housing shell 3 is fixedly connected to the top of the base 2. Rollers 4 are rotatably connected to the outer wall of the press-fitting fixture body 1. Four sets of rollers 4 are arranged in a rectangular array on the outer wall of the press-fitting fixture body 1. The bottom of the rollers 4 is in contact with the top of the base 2. A connecting rod 5 is hinged to the outer wall of the press-fitting fixture body 1. A connecting shaft 6 is rotatably connected to the inner wall of the connecting rod 5. A connecting rod 7 is rotatably connected to the outer wall of the connecting shaft 6. A support shaft 8 is rotatably connected to the inner wall of the connecting rod 7. The outer wall of the support shaft 8 is rotatably connected to the inner wall of the bracket.
[0032] Reference Figures 2-4A driven gear 9 is fixedly connected to the outer wall of the support shaft 8. Two sets of connecting rod 5, connecting rod 7, driven gear 9 and driving gear 12 are respectively arranged and symmetrically arranged with the central axis of the press fixture body 1 as the axis of symmetry. A motor 10 is fixedly connected to the top of the base 2 through a bracket. A rotating shaft 11 is fixedly connected to the output end of the motor 10. A driving gear 12 is fixedly connected to the outer wall of the rotating shaft 11. The driven gear 9 meshes with the driving gear 12. The motor 10 slowly drives the rotating shaft 11 to rotate. Through the meshing of the driving gear 12 and the driven gear 9, the connecting rod 7 and the connecting rod 5 drive the press fixture body 1 to be stored from the outside of the storage shell 3 into the inside of the storage shell 3.
[0033] Reference Figure 2 A limiting hole 13 is provided at the center of the roller 4. The limiting hole 13 is cylindrically recessed. A mounting plate 14 is fixedly connected to the top of the base 2. A T-shaped rod 15 is slidably connected to the inner wall of the mounting plate 14. The T-shaped rod 15 passes through the mounting plate 14. The outer wall of the T-shaped rod 15 is adapted to the inner wall of the limiting hole 13. A spring 16 is fixedly connected to the side wall of the mounting plate 14. The limiting hole 13 is cylindrically recessed. The limiting hole 13, the mounting plate 14, the T-shaped rod 15 and the spring 16 form a limiting assembly. There are two sets of limiting assemblies, which are distributed in a mirror image. When the pressing fixture body 1 is moved from the storage shell 3 to the base 2, the roller 4 can squeeze the spring 16 to retract when it rolls. When the two sets of rollers 4 on both sides move to the edge of the base 2, the T-shaped rod 15 can be inserted into the limiting hole 13 to position the roller 4.
[0034] Working principle: During the storage process, after the motor 10 on the top of the base 2 starts, it slowly drives the output shaft 11 to rotate. Since the driving gear 12 fixed on the outer wall of the shaft 11 meshes with the driven gear 9 on the outer wall of the support shaft 8, the support shaft 8 rotates. The rotation of the support shaft 8 drives the connected connecting rod 7 to move. The connecting rod 7 is linked to the connecting rod 5 through the connecting shaft 6. The connecting rod 5 is hinged to the pressing fixture body 1. Under the transmission action of this series of connecting rods, the pressing fixture body 1 slides on the top of the base 2 with the help of the four sets of rectangular array rollers 4 on the outer wall, and is gradually pulled from the outside of the storage shell 3 to the inside of the storage shell 3 to complete the storage action. When it is necessary to press the fixture... When the clamp body 1 is removed from the storage shell 3 for use, the motor 10 rotates in reverse. Through the reverse transmission of two sets of gears and two sets of connecting rods, the clamp body 1 moves outward. During this process, the roller 4 rolls and squeezes the T-bar 15 on the mounting plate 14, causing the spring 16 to contract and temporarily release the T-bar 15 from the restriction of the roller 4. When the clamp body 1 is completely moved to the edge of the base 2 and the rollers 4 on both sides reach a specific position, the spring 16 returns to its original shape and pushes the T-bar 15 into the limiting hole 13 in the center of the roller 4. The limiting component is used to position the roller 4, thereby ensuring that the clamp body 1 is stably in the working position for subsequent oil seal clamping operations.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
