Support rod 1 end portion fixedly installed with screw rod 2, support rod 1 is arranged coaxially with screw rod 2, the outside of screw rod 2 is threadedly sleeved with linkage handle 3, staff holds linkage handle 3 with one hand, and rotates support rod 1 with the other hand and drives screw rod 2 to rotate, and screw rod 2 can be relative between linkage handle 3 and moves while rotating, can adjust the position of linkage handle 3 on screw rod 2.

[0021] The inside of linkage handle 3 both ends is slidably provided with movable block 5, and the both ends of linkage handle 3 are threadedly penetrated with adjusting rod 6, the length direction of adjusting rod 6 is perpendicular to the length direction of screw rod 2, and the end portion of adjusting rod 6 extending to the inside of linkage handle 3 is rotatably connected with one side of movable block 5, and staff can drive movable block 5 to move in linkage handle 3 by rotating adjusting rod 6. The inside of one end of movable block 5 is threadedly connected with pressing rod 7, and screw rod 2 and pressing rod 7 are arranged parallel to each other in the length direction, and movable block 5 can drive pressing rod 7 to move, and the distance between the both sides of pressing rod 7 can be adjusted by rotating the corresponding adjusting rod 6. The end portion of pressing rod 7 extends to the outside of linkage handle 3, and the end portion of pressing rod 7 extending to the outside of linkage handle 3 is fixedly installed with first pressing block 8, and pressing rod 7 presses oil seal through first pressing block 8. The end portion of screw rod 2 away from support rod 1 is fixedly installed with second pressing block 9, and screw rod 2 presses oil seal through second pressing block 9.

[0022] In the process of installing oil seal, if the diameter of oil seal is not much different from the diameter of screw rod 2, linkage handle 3 can be adjusted to the position close to support rod 1, first pressing block 8 is closer to support 1, and second pressing block 9 is protruded alone, that is, the state shown in the drawings, at this time, the inverted triangle shape is formed between the two first pressing blocks 8 and the second pressing block 9, and then the second pressing block 9 is abutted against the surface of oil seal, one hand of staff fixes the position of linkage handle 3, and the other hand holds impact handle 13 and hits the end portion of screw rod 2 downwards, so that the impact force can be transmitted to second pressing block 9 through screw rod 2, and oil seal can be pressed into workpiece inside by second pressing block 9. Figure 1 If the diameter of oil seal is obviously larger than the diameter of screw rod 2, the distance between first pressing block 8 can be adjusted according to the specific diameter of oil seal, first pressing block 8 is away from support rod 1 through screw rod 2, the inverted triangle shape is formed between the two first pressing blocks 8 and the second pressing block 9, the distance between the two first pressing blocks 8 is adjusted by rotating adjusting rod 6, and the two first pressing blocks 8 are just pressed on the two sides of oil seal, and then staff hits screw rod 2 by impact handle 13, and screw rod 2 transmits the impact force to pressing rod 7 and first pressing block 8 through linkage handle 3, and the two sides of oil seal can be pressed by first pressing block 8, and then the position of first pressing block 8 contacting oil seal is adjusted, and oil seal is pressed into workpiece inside.

[0023] The indicating needle 10 is fixedly installed at the end of the movable block 5 away from the end of the pressing rod 7, and the movable block 5 can drive the indicating needle 10 to move, and the indicating needle 10 extends to the outside of the linkage handle 3, and the linkage handle 3 is uniformly marked with scales, so that the position of the indicating needle 10 can be indicated, and the positions of the movable block 5 and the pressing rod 7 can be roughly understood. When adjusting the distance between the pressing rods 7, the distance between the pressing rods 7 and the screw rod 2 on both sides can be roughly the same, so that the distance between the pressing rods 7 and the screw rod 2 on both sides is not too large, and the impact handle 3 is not tilted when hitting.

[0024] Working principle: during the use of the oil seal pressing device, if the diameter of the oil seal is similar to the diameter of the screw rod 2, the second pressing block 9 is farther away from the support rod 1 than the first pressing block 8, the worker holds the second pressing block 9 against the surface of the oil seal to be pressed, holds the adjusting handle 3 with one hand and holds the impact handle 13 to hit the screw rod 2 with the other hand, and the screw rod 2 can drive the second pressing block 9 to press the oil seal. If the diameter of the oil seal is obviously larger than the diameter of the screw rod 2, the second pressing block 9 is closer to the support rod 1 than the first pressing block 8, the worker rotates the adjusting rod 6 to drive the movable block 5 to move, and the movable block 5 drives the pressing rod 7 to move, and the distance between the two pressing rods 7 is adjusted according to the diameter of the oil seal, so that the two first pressing blocks 8 are just pressed against the surfaces of the oil seal on both sides. When the worker uses the impact handle 13 to drive the first pressing block 8 to press the oil seal, the oil seal is pressed into the workpiece, and part of the oil seal is not pressed into the workpiece, then the worker adjusts the position of the two first pressing blocks 8 abutting against the oil seal, and continues to use the impact handle 13 to impact and press, so that the oil seal is completely pressed into the workpiece. The oil seal pressing device can press different diameter oil seals into the workpiece, and is convenient to adjust and press.

[0025] Embodiment 2: in embodiment 1, the device can only press different diameter oil seals into the workpiece, but cannot take out the oil seal from the workpiece, and needs to use a dismounting tool to take out the oil seal, which is not convenient to use. Therefore, this embodiment is proposed. Refer to Figure 4, as another preferred embodiment of the utility model, on the basis of example 1, still include pull rod 11, pull rod 11 end extends to the inside of linkage handle 3 and is connected with the internal thread of movable block 5, pull rod 11 has a hook, after installing two pull rods 11 inside movable block 5, the hook tip direction of two pull rod 11 end approaches each other, when removing oil seal, the distance between two pull rod 11 is adjusted through adjusting rod 6, so that two pull rod 11 can be inserted into the outside of oil seal, then two pull rod 11 are driven to approach each other through adjusting rod 6, oil seal is clamped through two pull rod 11, finally, staff holds linkage handle 3 with one hand, and the other hand uses impact handle 13 to hit the end of support rod 1 away from screw rod 2, so that pull rod 11 can be pulled out of oil seal by impact force.

[0026] Example 3: in example 2, when pulling out oil seal by pull rod 11, it is more suitable for the oil seal with thinner thickness, if the thickness of oil seal is thicker, pull rod 11 cannot hook oil seal, and pull rod 11 is easy to separate from the two sides of oil seal, therefore, this embodiment is proposed. Refer to Figure 5 , as another preferred embodiment of the utility model, on the basis of example 2, still include hook rod 12, hook rod 12 end extends to the inside of linkage handle 3 and is connected with the internal thread of movable block 5, the spacing between two hook rod 12 can be adjusted by rotating adjusting rod 6, hook rod 12, pull rod 11 and pressure bar 7 can be conveniently disassembled, and corresponding tools are selected according to the need to work. Hook rod 12 is hooked into the inside of oil seal, and staff can make oil seal be hooked out by using impact handle 12, and the oil seal with inconsistent thickness can be hooked out and removed.

[0027] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and all should be covered in the protection scope of the utility model.
