Description

Technical Field

[0001] This utility model relates to the field of sealing structure technology, specifically a high-sealing automotive transmission oil seal sealing structure. Background Technology

[0002] Before leaving the factory, automotive transmissions must undergo rigorous airtightness testing. The oil seal sealing process involves inserting two precision-machined round rods into the transmission oil seal, ensuring a tight seal between the oil seal and the rods.

[0003] Utility model patent CN219062389U discloses a method for sealing an automotive transmission oil seal. The method includes an adjusting box, a transmission rod rotatably connected to the back of the inner wall of the adjusting box, a drive gear connected to the surface of the transmission rod, and a drive rack slidably connected to the top and bottom of the inner wall of the adjusting box. The drive rack meshes with the drive gear, and one end of the drive rack passes through the adjusting box and extends to the outside of the adjusting box. This method allows for adjustment of the sealing component's position using a drive gear, drive rack, threaded cylinder, and adjusting screw. This allows the sealing component to adapt to different transmission models and sizes, and its position can be adjusted to fit different oil seal locations on different transmissions. Fine-tuning of the sealing component can be achieved using a fine-tuning screw, mounting plate, and knob, ensuring a better fit and sealing of the oil seal.

[0004] In the aforementioned prior art, during the use of the sealing device, the plug of the oil seal is inconvenient to disassemble, and because oil seals vary in size and model, insufficient contact between the plug and the oil seal when they do not match will affect the sealing effect. Therefore, improvements are needed. Utility Model Content

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The adjusting mechanism 8 includes a slanted groove 81. A slanted groove 81 is formed inside the connecting sleeve 10. A slanted block 82 is slidably connected inside the slanted groove 81. Multiple slanted grooves 81 are evenly distributed inside the connecting sleeve 10. By designing multiple slanted grooves 81, the slanted block 82 can be inserted into the slanted grooves 81 at different positions. A sliding seat 83 is slidably sleeved on the outside of the slanted block 82, and the sliding seat 83 is slidably connected to the connecting sleeve 10. A fixing rod 84 is slidably sleeved inside the slanted block 82, and the fixing rod 84 is fixedly connected to the sliding seat 83. A first spring 85 is provided on the outer side of the fixed rod 84. One end of the first spring 85 is fixedly connected to the inclined block 82, and the other end of the first spring 85 is fixedly connected to the slide block 83. By designing the first spring 85, the force of the first spring 85 can be applied to the inclined block 82. A connecting block 86 is fixedly connected to the outer side of the inclined block 82. The connecting block 86 is slidably connected to the slide block 83. The slide block 83 is fixedly connected to the connecting rod 7. A handle 87 is fixedly connected to the outer side of the connecting sleeve 10. By designing the adjustment mechanism 8, the height of the plug 13 can be easily adjusted.

[0025] Please see Figure 1 , Figure 2 , Figure 5The connecting mechanism 9 includes an annular groove 91. The connecting column 12 has an annular groove 91 inside. Two symmetrically distributed balls 92 are movably sleeved inside the annular groove 91. The balls 92 are movably connected to the mounting base 11. A slider 93 is movably sleeved on the outside of the balls 92. The slider 93 is slidably connected to the mounting base 11. A limit block 94 is fixedly connected to the outside of the slider 93.

One end of the second spring 95 is fixedly connected to the mounting base 11, and the other end of the second spring 95 is fixedly connected to the limit block 94. By designing the second spring 95, the force of the second spring 95 can act on the limit block 94. By designing the connecting mechanism 9, it is convenient to disassemble the plug 13.

[0026] The specific implementation process of this utility model is as follows: When it is necessary to seal the oil seal, start the dual-axis motor 2. The output end of the dual-axis motor 2 drives the screw 3 to rotate, so that the screw sleeve 4 makes threaded movement. Both screw sleeves 4 slide horizontally inside the fixed seat 1. At the same time, the screw sleeve 4 will drive the guide block 5 to slide along the fixed seat 1. The screw sleeve 4 drives the connecting rod 7 and the connecting sleeve 10 to move horizontally. The connecting sleeve 10 can drive the mounting seat 11 and the plug 13 to move horizontally. The oil seal can be sealed by inserting the plug 13.

[0027] When the plug 13 needs to be disassembled, simply pull the plug 13 outwards. The plug 13 will cause the connecting post 12 to move horizontally. The connecting post 12 will slide along the ball 92. The arc surface of the annular groove 91 inside the connecting post 12 will squeeze and push the ball 92 to move. The ball 92 will drive the slider 93 to move. The slider 93 will drive the limit block 94 to move. The limit block 94 will squeeze the second spring 95, which can separate the annular groove 91 from the ball 92. Then the connecting post 12 can be pulled out from the mounting base 11 to remove the plug 13, which is convenient for replacing the plug 13. It has a higher fit and better sealing performance when sealing oil seals of different sizes and models.

[0028] When the height of the plug 13 needs to be adjusted, push and pull the handle 87 vertically. The handle 87 moves the connecting sleeve 10. The inclined groove 81 inside the connecting sleeve 10 will slide relative to the inclined block 82. The inclined block 82 will be squeezed and pushed into the slide seat 83. The inclined block 82 can slide along the fixed rod 84 to squeeze the first spring 85, which can separate the inclined block 82 from the inclined groove 81. As the connecting sleeve 10 moves, the elastic action of the first spring 85 will give the inclined block 82 an outward push force, which can insert the inclined block 82 into the inclined groove 81 at another position. This can realize the insertion and cooperation of the inclined block 82 with the inclined groove 81 at different positions, which is convenient for adjusting and fixing the relative position of the slide seat 83 and the connecting sleeve 10, and facilitates the adjustment of the height of the connecting sleeve 10 and the plug 13.
